sl@0	1	Recent user-visible changes to Tcl:
sl@0	2
sl@0	3	RCS: @(#) $Id: changes,v 1.79.2.50 2007/05/16 22:13:07 das Exp $
sl@0	4
sl@0	5	1. No more [command1] [command2] construct for grouping multiple
sl@0	6	commands on a single command line.
sl@0	7
sl@0	8	2. Semi-colon now available for grouping commands on a line.
sl@0	9
sl@0	10	3. For a command to span multiple lines, must now use backslash-return
sl@0	11	at the end of each line but the last.
sl@0	12
sl@0	13	4. "Var" command has been changed to "set".
sl@0	14
sl@0	15	5. Double-quotes now available as an argument grouping character.
sl@0	16
sl@0	17	6. "Return" may be used at top-level.
sl@0	18
sl@0	19	7. More backslash sequences available now. In particular, backslash-newline
sl@0	20	may be used to join lines in command files.
sl@0	21
sl@0	22	8. New or modified built-in commands: case, return, for, glob, info,
sl@0	23	print, return, set, source, string, uplevel.
sl@0	24
sl@0	25	9. After an error, the variable "errorInfo" is filled with a stack
sl@0	26	trace showing what was being executed when the error occurred.
sl@0	27
sl@0	28	10. Command abbreviations are accepted when parsing commands, but
sl@0	29	are not recommended except for purely-interactive commands.
sl@0	30
sl@0	31	11. $, set, and expr all complain now if a non-existent variable is
sl@0	32	referenced.
sl@0	33
sl@0	34	12. History facilities exist now. See Tcl.man and Tcl_RecordAndEval.man.
sl@0	35
sl@0	36	13. Changed to distinguish between empty variables and those that don't
sl@0	37	exist at all. Interfaces to Tcl_GetVar and Tcl_ParseVar have changed
sl@0	38	(NULL return value is now possible). * POTENTIAL INCOMPATIBILITY *
sl@0	39
sl@0	40	14. Changed meaning of "level" argument to "uplevel" command (1 now means
sl@0	41	"go up one level", not "go to level 1"; "#1" means "go to level 1").
sl@0	42	* POTENTIAL INCOMPATIBILITY *
sl@0	43
sl@0	44	15. 3/19/90 Added "info exists" option to see if variable exists.
sl@0	45
sl@0	46	16. 3/19/90 Added "noAbbrev" variable to prohibit command abbreviations.
sl@0	47
sl@0	48	17. 3/19/90 Added extra errorInfo option to "error" command.
sl@0	49
sl@0	50	18. 3/21/90 Double-quotes now only affect space: command, variable,
sl@0	51	and backslash substitutions still occur inside double-quotes.
sl@0	52	* POTENTIAL INCOMPATIBILITY *
sl@0	53
sl@0	54	19. 3/21/90 Added support for \r.
sl@0	55
sl@0	56	20. 3/21/90 List, concat, eval, and glob commands all expect at least
sl@0	57	one argument now. * POTENTIAL INCOMPATIBILITY *
sl@0	58
sl@0	59	21. 3/22/90 Added "?:" operators to expressions.
sl@0	60
sl@0	61	22. 3/25/90 Fixed bug in Tcl_Result that caused memory to get trashed.
sl@0	62
sl@0	63	------------------- Released version 3.1 ---------------------
sl@0	64
sl@0	65	23. 3/29/90 Fixed bug that caused "file a.b/c ext" to return ".b/c".
sl@0	66
sl@0	67	24. 3/29/90 Semi-colon is not treated specially when enclosed in
sl@0	68	double-quotes.
sl@0	69
sl@0	70	------------------- Released version 3.2 ---------------------
sl@0	71
sl@0	72	25. 4/16/90 Rewrote "exec" not to use select or signals anymore.
sl@0	73	Should be more Sys-V compatible, and no slower in the normal case.
sl@0	74
sl@0	75	26. 4/18/90 Rewrote "glob" to eliminate GNU code (there's no GNU code
sl@0	76	left in Tcl, now), and added Tcl_TildeSubst procedure. Added automatic
sl@0	77	tilde-substitution in many commands, including "glob".
sl@0	78
sl@0	79	------------------- Released version 3.3 ---------------------
sl@0	80
sl@0	81	27. 7/11/90 Added "Tcl_AppendResult" procedure.
sl@0	82
sl@0	83	28. 7/20/90 "History" with no options now defaults to "history info"
sl@0	84	rather than to "history redo". Although this is a backward incompatibility,
sl@0	85	it should only be used interactively and thus shouldn't present any
sl@0	86	compatibility problems with scripts.
sl@0	87
sl@0	88	29. 7/20/90 Added "Tcl_GetInteger", "Tcl_GetDouble", and "Tcl_GetBoolean"
sl@0	89	procedures.
sl@0	90
sl@0	91	30. 7/22/90 Removed "Tcl_WatchInterp" procedure: doesn't seem to be
sl@0	92	necessary, since the same effect can be achieved with the deletion
sl@0	93	callbacks on individual commands. * POTENTIAL INCOMPATIBILITY *
sl@0	94
sl@0	95	31. 7/23/90 Added variable tracing: Tcl_TraceVar, Tcl_UnTraceVar,
sl@0	96	and Tcl_VarTraceInfo procedures, "trace" command.
sl@0	97
sl@0	98	32. 8/9/90 Mailed out list of all bug fixes since 3.3 release.
sl@0	99
sl@0	100	33. 8/29/90 Fixed bugs in Tcl_Merge relating to backslashes and
sl@0	101	semi-colons. Mailed out patch.
sl@0	102
sl@0	103	34. 9/3/90 Fixed bug in tclBasic.c: quotes weren't quoting ]'s.
sl@0	104	Mailed out patch.
sl@0	105
sl@0	106	35. 9/19/90 Rewrote exec to always use files both for input and
sl@0	107	output to the process. The old pipe-based version didn't work if
sl@0	108	the exec'ed process forked a child and then exited: Tcl waited
sl@0	109	around for stdout to get closed, which didn't happen until the
sl@0	110	grandchild exited.
sl@0	111
sl@0	112	36. 11/5/90 ERR_IN_PROGRESS flag wasn't being cleared soon enough
sl@0	113	in Tcl_Eval, allowing error messages from different commands to
sl@0	114	pile up in $errorInfo. Fixed by re-arranging code in Tcl_Eval that
sl@0	115	re-initializes result and ERR_IN_PROGRESS flag. Didn't mail out
sl@0	116	patch: changes too complicated to describe.
sl@0	117
sl@0	118	37. 12/19/90 Added Tcl_VarEval procedure as a convenience for
sl@0	119	assembling and executing Tcl commands.
sl@0	120
sl@0	121	38. 1/29/91 Fixed core leak in Tcl_AddErrorInfo. Also changed procedure
sl@0	122	and Tcl_Eval so that first call to Tcl_AddErrorInfo need not come from
sl@0	123	Tcl_Eval.
sl@0	124
sl@0	125	----------------- Released version 5.0 with Tk ------------------
sl@0	126
sl@0	127	39. 4/3/91 Removed change bars from manual entries, leaving only those
sl@0	128	that came after version 3.3 was released.
sl@0	129
sl@0	130	40. 5/17/91 Changed tests to conform to Mary Ann May-Pumphrey's approach.
sl@0	131
sl@0	132	41. 5/23/91 Massive revision to Tcl parser to simplify the implementation
sl@0	133	of string and floating-point support in expressions. Newlines inside
sl@0	134	[] are now treated as command separators rather than word separators
sl@0	135	(this makes newline treatment consistent throughout Tcl).
sl@0	136	* POTENTIAL INCOMPATIBILITY *
sl@0	137
sl@0	138	42. 5/23/91 Massive rewrite of expression code to support floating-point
sl@0	139	values and simple string comparisons. The C interfaces to expression
sl@0	140	routines have changed (Tcl_Expr is replaced by Tcl_ExprLong, Tcl_ExprDouble,
sl@0	141	etc.), but all old Tcl expression strings should be accepted by the new
sl@0	142	expression code.
sl@0	143	* POTENTIAL INCOMPATIBILITY *
sl@0	144
sl@0	145	43. 5/23/91 Modified tclHistory.c to check for negative "keep" value.
sl@0	146
sl@0	147	44. 5/23/91 Modified Tcl_Backslash to handle backslash-newline. It now
sl@0	148	returns 0 to indicate that a backslash sequence should be replaced by
sl@0	149	no character at all.
sl@0	150	* POTENTIAL INCOMPATIBILITY *
sl@0	151
sl@0	152	45. 5/29/91 Modified to use ANSI C function prototypes. Must set
sl@0	153	"USE_ANSI" switch when compiling to get prototypes.
sl@0	154
sl@0	155	46. 5/29/91 Completed test suite by providing tests for all of the
sl@0	156	built-in Tcl commands.
sl@0	157
sl@0	158	47. 5/29/91 Changed Tcl_Concat to eliminate leading and trailing
sl@0	159	white-space in each of the things it concatenates and to ignore
sl@0	160	elements that are empty or have only white space in them. This
sl@0	161	produces cleaner output from the "concat" command.
sl@0	162	* POTENTIAL INCOMPATIBILITY *
sl@0	163
sl@0	164	48. 5/31/91 Changed "set" command and Tcl_SetVar procedure to return
sl@0	165	new value of variable.
sl@0	166
sl@0	167	49. 6/1/91 Added "while" and "cd" commands.
sl@0	168
sl@0	169	50. 6/1/91 Changed "exec" to delete the last character of program
sl@0	170	output if it is a newline. In most cases this makes it easier to
sl@0	171	process program-generated output.
sl@0	172	* POTENTIAL INCOMPATIBILITY *
sl@0	173
sl@0	174	51. 6/1/91 Made sure that pointers are never used after freeing them.
sl@0	175
sl@0	176	52. 6/1/91 Fixed bug in TclWordEnd where it wasn't dealing with
sl@0	177	[] inside quotes correctly.
sl@0	178
sl@0	179	53. 6/8/91 Fixed exec.test to accept return values of either 1 or
sl@0	180	255 from "false" command.
sl@0	181
sl@0	182	54. 7/6/91 Massive overhaul of variable management. Associative
sl@0	183	arrays now available, along with "unset" command (and Tcl_UnsetVar
sl@0	184	procedure). Variable traces have been completely reworked:
sl@0	185	interfaces different both from Tcl and C, and multiple traces may
sl@0	186	exist on same variable. Can no longer redefine existing local
sl@0	187	variable to be global. Calling sequences have changed slightly
sl@0	188	for Tcl_GetVar and Tcl_SetVar ("global" is now "flags"). Tcl_SetVar
sl@0	189	can fail and return a NULL result. New forms of variable-manipulation
sl@0	190	procedures: Tcl_GetVar2, Tcl_SetVar2, etc. Syntax of variable
sl@0	191	$-notation changed to support array indexing.
sl@0	192	* POTENTIAL INCOMPATIBILITY *
sl@0	193
sl@0	194	55. 7/6/91 Added new list-manipulation procedures: Tcl_ScanElement,
sl@0	195	Tcl_ConvertElement, Tcl_AppendElement.
sl@0	196
sl@0	197	56. 7/12/91 Created new procedure Tcl_EvalFile, which does most of the
sl@0	198	work of the "source" command.
sl@0	199
sl@0	200	57. 7/20/91 Major reworking of "exec" command to allow pipelines,
sl@0	201	more redirection, background. Added new procedures Tcl_Fork,
sl@0	202	Tcl_WaitPids, Tcl_DetachPids, and Tcl_CreatePipeline. The old
sl@0	203	"< input" notation has been replaced by "<< input" ("<" is for
sl@0	204	redirection from a file). Also handles error returns and abnormal
sl@0	205	terminations (e.g. signals) differently.
sl@0	206	* POTENTIAL INCOMPATIBILITY *
sl@0	207
sl@0	208	58. 7/21/91 Added "append" and "lappend" commands.
sl@0	209
sl@0	210	59. 7/22/91 Reworked error messages and manual entries to use
sl@0	211	?x? as the notation for an optional argument x, instead of [x]. The
sl@0	212	bracket notation was often confused with the use of brackets for
sl@0	213	command substitution. Also modified error messages to be more
sl@0	214	consistent.
sl@0	215
sl@0	216	60. 7/23/91 Tcl_DeleteCommand now returns an indication of whether
sl@0	217	or not the command actually existed, and the "rename" command uses
sl@0	218	this information to return an error if an attempt is made to delete
sl@0	219	a non-existent command.
sl@0	220	* POTENTIAL INCOMPATIBILITY *
sl@0	221
sl@0	222	61. 7/25/91 Added new "errorCode" mechanism, along with procedures
sl@0	223	Tcl_SetErrorCode, Tcl_UnixError, and Tcl_ResetResult. Renamed
sl@0	224	Tcl_Return to Tcl_SetResult, but left a #define for Tcl_Return to
sl@0	225	avoid compatibility problems.
sl@0	226
sl@0	227	62. 7/26/91 Extended "case" command with alternate syntax where all
sl@0	228	patterns and commands are together in a single list argument: makes
sl@0	229	it easier to write multi-line case statements.
sl@0	230
sl@0	231	63. 7/27/91 Changed "print" command to perform tilde-substitution on
sl@0	232	the file name.
sl@0	233
sl@0	234	64. 7/27/91 Added "tolower", "toupper", "trim", "trimleft", and "trimright"
sl@0	235	options to "string" command.
sl@0	236
sl@0	237	65. 7/29/91 Added "atime", "mtime", "size", and "stat" options to "file"
sl@0	238	command.
sl@0	239
sl@0	240	66. 8/1/91 Added "split" and "join" commands.
sl@0	241
sl@0	242	67. 8/11/91 Added commands for file I/O, including "open", "close",
sl@0	243	"read", "gets", "puts", "flush", "eof", "seek", and "tell".
sl@0	244
sl@0	245	68. 8/14/91 Switched to use a hash table for command lookups. Command
sl@0	246	abbreviations no longer have direct support in the Tcl interpreter, but
sl@0	247	it should be possible to simulate them with the auto-load features
sl@0	248	described below. The "noAbbrev" variable is no longer used by Tcl.
sl@0	249	* POTENTIAL INCOMPATIBILITY *
sl@0	250
sl@0	251	68.5 8/15/91 Added support for "unknown" command, which can be used to
sl@0	252	complete abbreviations, auto-load library files, auto-exec shell
sl@0	253	commands, etc.
sl@0	254
sl@0	255	69. 8/15/91 Added -nocomplain switch to "glob" command.
sl@0	256
sl@0	257	70. 8/20/91 Added "info library" option and TCL_LIBRARY #define. Also
sl@0	258	added "info script" option.
sl@0	259
sl@0	260	71. 8/20/91 Changed "file" command to take "option" argument as first
sl@0	261	argument (before file name), for consistency with other Tcl commands.
sl@0	262	* POTENTIAL INCOMPATIBILITY *
sl@0	263
sl@0	264	72. 8/20/91 Changed format of information in $errorInfo variable:
sl@0	265	comments such as
sl@0	266	("while" body line 1)
sl@0	267	are now on separate lines from commands being executed.
sl@0	268	* POTENTIAL INCOMPATIBILITY *
sl@0	269
sl@0	270	73. 8/20/91 Changed Tcl_AppendResult so that it (eventually) frees
sl@0	271	large buffers that it allocates.
sl@0	272
sl@0	273	74. 8/21/91 Added "linsert", "lreplace", "lsearch", and "lsort"
sl@0	274	commands.
sl@0	275
sl@0	276	75. 8/28/91 Added "incr" and "exit" commands.
sl@0	277
sl@0	278	76. 8/30/91 Added "regexp" and "regsub" commands.
sl@0	279
sl@0	280	77. 9/4/91 Changed "dynamic" field in interpreters to "freeProc" (procedure
sl@0	281	address). This allows for alternative storage managers.
sl@0	282	* POTENTIAL INCOMPATIBILITY *
sl@0	283
sl@0	284	78. 9/6/91 Added "index", "length", and "range" options to "string"
sl@0	285	command. Added "lindex", "llength", and "lrange" commands.
sl@0	286
sl@0	287	79. 9/8/91 Removed "index", "length", "print" and "range" commands.
sl@0	288	"Print" is redundant with "puts", but less general, and the other
sl@0	289	commands are replaced with the new commands described in change 78
sl@0	290	above.
sl@0	291	* POTENTIAL INCOMPATIBILITY *
sl@0	292
sl@0	293	80. 9/8/91 Changed history revision to occur even when history command
sl@0	294	is nested; needed in order to allow "history" to be invoked from
sl@0	295	"unknown" procedure.
sl@0	296
sl@0	297	81. 9/13/91 Changed "panic" not to use vfprintf (it's uglier and less
sl@0	298	general now, but makes it easier to run Tcl on systems that don't
sl@0	299	have vfprintf). Also changed "strerror" not to redeclare sys_errlist.
sl@0	300
sl@0	301	82. 9/19/91 Lots of changes to improve portability to different UNIX
sl@0	302	systems, including addition of "config" script to adapt Tcl to the
sl@0	303	configuration of the system it's being compiled on.
sl@0	304
sl@0	305	83. 9/22/91 Added "pwd" command.
sl@0	306
sl@0	307	84. 9/22/91 Renamed manual pages so that their filenames are no more
sl@0	308	than 14 characters in length, moved to "doc" subdirectory.
sl@0	309
sl@0	310	85. 9/24/91 Redid manual entries so they contain the supplemental
sl@0	311	macros that they need; can just print with "troff -man" or "man"
sl@0	312	now.
sl@0	313
sl@0	314	86. 9/26/91 Created initial version of script library, including
sl@0	315	a version of "unknown" that does auto-loading, auto-execution, and
sl@0	316	abbreviation expansion. This library is used by tclTest
sl@0	317	automatically. See the "library" manual entry for details.
sl@0	318
sl@0	319	----------------- Released version 6.0, 9/26/91 ------------------
sl@0	320
sl@0	321	87. 9/30/91 Made "string tolower" and "string toupper" check case
sl@0	322	before converting: on some systems, "tolower" and "toupper" assume
sl@0	323	that character already has particular case.
sl@0	324
sl@0	325	88. 9/30/91 Fixed bug in Tcl_SetResult: wasn't always setting freeProc
sl@0	326	correctly when called with NULL value. This tended to cause memory
sl@0	327	allocation errors later.
sl@0	328
sl@0	329	89. 10/3/91 Added "upvar" command.
sl@0	330
sl@0	331	90. 10/4/91 Changed "format" so that internally it converts %D to %ld,
sl@0	332	%U to %lu, %O to %lo, and %F to %f. This eliminates some compatibility
sl@0	333	problems on some machines without affecting behavior.
sl@0	334
sl@0	335	91. 10/10/91 Fixed bug in "regsub" that caused core dumps with the -all
sl@0	336	option when the last match wasn't at the end of the string.
sl@0	337
sl@0	338	92. 10/17/91 Fixed problems with backslash sequences: \r support was
sl@0	339	incomplete and \f and \v weren't supported at all.
sl@0	340
sl@0	341	93. 10/24/91 Added Tcl_InitHistory procedure.
sl@0	342
sl@0	343	94. 10/24/91 Changed "regexp" to store "-1 -1" in subMatchVars that
sl@0	344	don't match, rather than returning an error.
sl@0	345
sl@0	346	95. 10/27/91 Modified "regexp" to return actual strings in matchVar
sl@0	347	and subMatchVars instead of indices. Added "-indices" switch to cause
sl@0	348	indices to be returned.
sl@0	349	* POTENTIAL INCOMPATIBILITY *
sl@0	350
sl@0	351	96. 10/27/91 Fixed bug in "scan" where it used hardwired constants for
sl@0	352	sizes of floats and doubles instead of using "sizeof".
sl@0	353
sl@0	354	97. 10/31/91 Fixed bug in tclParse.c where parse-related error messages
sl@0	355	weren't being storage-managed correctly, causing spurious free's.
sl@0	356
sl@0	357	98. 10/31/91 Form feed and vertical tab characters are now considered
sl@0	358	to be space characters by the parser.
sl@0	359
sl@0	360	99. 10/31/91 Added TCL_LEAVE_ERR_MSG flag to procedures like Tcl_SetVar.
sl@0	361
sl@0	362	100. 11/7/91 Fixed bug in "case" where "in" argument couldn't be omitted
sl@0	363	if all case branches were embedded in a single list.
sl@0	364
sl@0	365	101. 11/7/91 Switched to use "pid_t" and "uid_t" and other official
sl@0	366	POSIC types and function prototypes.
sl@0	367
sl@0	368	----------------- Released version 6.1, 11/7/91 ------------------
sl@0	369
sl@0	370	102. 12/2/91 Modified Tcl_ScanElement and Tcl_ConvertElement in several
sl@0	371	ways. First, allowed caller to request that only backslashes be used
sl@0	372	(no braces). Second, made Tcl_ConvertElement more aggressive in using
sl@0	373	backslashes for braces and quotes.
sl@0	374
sl@0	375	103. 12/5/91 Added "type", "lstat", and "readlink" options to "file"
sl@0	376	command, plus added new "type" element to output of "stat" and "lstat"
sl@0	377	options.
sl@0	378
sl@0	379	104. 12/10/91 Manual entries had first lines that caused "man" program
sl@0	380	to try weird preprocessor. Added blank comment lines to fix problem.
sl@0	381
sl@0	382	105. 12/16/91 Fixed a few bugs in auto_mkindex proc: wasn't handling
sl@0	383	errors properly, and hadn't been upgraded for new "regexp" syntax.
sl@0	384
sl@0	385	106. 1/2/92 Fixed bug in "file" command where it didn't properly handle
sl@0	386	a file names containing tildes where the indicated user doesn't exist.
sl@0	387
sl@0	388	107. 1/2/92 Fixed lots of cases in tclUnixStr.c where two different
sl@0	389	errno symbols (e.g. EWOULDBLOCK and EAGAIN) have the same number; Tcl
sl@0	390	will only use one of them.
sl@0	391
sl@0	392	108. 1/2/92 Lots of changes to configuration script to handle many more
sl@0	393	systems more gracefully. E.g. should now detect the bogus strtoul that
sl@0	394	comes with AIX and substitute Tcl's own version instead.
sl@0	395
sl@0	396	----------------- Released version 6.2, 1/10/92 ------------------
sl@0	397
sl@0	398	109. 1/20/92 Config didn't have code to actually use "uid_t" variable
sl@0	399	to set TCL_UIT_T #define.
sl@0	400
sl@0	401	110. 2/10/92 Tcl_Eval didn't properly reset "numLevels" variable when
sl@0	402	too-deep recursion occurred.
sl@0	403
sl@0	404	111. 2/29/92 Added "on" and "off" to keywords accepted by Tcl_GetBoolean.
sl@0	405
sl@0	406	112. 3/19/92 Config wasn't installing default version of strtod.c for
sl@0	407	systems that don't have one in libc.a.
sl@0	408
sl@0	409	113. 3/23/92 Fixed bug in tclExpr.c where numbers with leading "."s,
sl@0	410	like 0.75, couldn't be properly substituted into expressions with
sl@0	411	variable or command substitution.
sl@0	412
sl@0	413	114. 3/25/92 Fixed bug in tclUnixAZ.c where "gets" command wasn't
sl@0	414	checking to make sure that it was able to write the variable OK.
sl@0	415
sl@0	416	115. 4/16/92 Fixed bug in tclUnixAZ.c where "read" command didn't
sl@0	417	compute file size right for device files.
sl@0	418
sl@0	419	116. 4/23/92 Fixed but in tclCmdMZ.c where "trace vinfo" was overwriting
sl@0	420	the trace command.
sl@0	421
sl@0	422	----------------- Released version 6.3, 5/1/92 ------------------
sl@0	423
sl@0	424	117. 5/1/92 Added Tcl_GlobalEval.
sl@0	425
sl@0	426	118. 6/1/92 Changed auto-load facility to source files at global level.
sl@0	427
sl@0	428	119. 6/8/92 Tcl_ParseVar wasn't always setting termPtr after errors, which
sl@0	429	sometimes caused core dumps.
sl@0	430
sl@0	431	120. 6/21/92 Fixed bug in initialization of regexp pattern cache. This
sl@0	432	bug caused segmentation violations in regexp commands under some conditions.
sl@0	433
sl@0	434	121. 6/22/92 Changed implementation of "glob" command to eliminate
sl@0	435	trailing slashes on directory names: they confuse some systems. There
sl@0	436	shouldn't be any user-visible changes in functionality except for names
sl@0	437	in error messages not having trailing slashes.
sl@0	438
sl@0	439	122. 7/2/92 Fixed bug that caused 'string match ** ""' to return 0.
sl@0	440
sl@0	441	123. 7/2/92 Fixed bug in Tcl_CreateCmdBuf where it wasn't initializing
sl@0	442	the buffer to an empty string.
sl@0	443
sl@0	444	124. 7/6/92 Fixed bug in "case" command where it used NULL pattern string
sl@0	445	after errors in the "default" clause.
sl@0	446
sl@0	447	125. 7/25/92 Speeded up auto_load procedure: don't reread all the index
sl@0	448	files unless the path has changed.
sl@0	449
sl@0	450	126. 8/3/92 Changed tclUnix.h to define MAXPATHLEN from PATH_MAX, not
sl@0	451	_POSIX_PATH_MAX.
sl@0	452
sl@0	453	----------------- Released version 6.4, 8/7/92 ------------------
sl@0	454
sl@0	455	127. 8/10/92 Changed tclBasic.c so that comment lines can be continued by
sl@0	456	putting a backslash before the newline.
sl@0	457
sl@0	458	128. 8/21/92 Modified "unknown" to allow the source-ing of a file for
sl@0	459	an auto-load to trigger other nested auto-loads, as long as there isn't
sl@0	460	any recursion on the same command name.
sl@0	461
sl@0	462	129. 8/25/92 Modified "format" command to allow " " and "+" flags, and
sl@0	463	allow flags in any order.
sl@0	464
sl@0	465	130. 9/14/92 Modified Tcl_ParseVar so that it doesn't actually attempt
sl@0	466	to look up the variable if "noEval" mode is in effect in the interpreter
sl@0	467	(it just parses the name). This avoids the errors that used to occur
sl@0	468	in statements like "expr {[info exists foo] && $foo}".
sl@0	469
sl@0	470	131. 9/14/92 Fixed bug in "uplevel" command where it didn't output the
sl@0	471	correct error message if a level was specified but no command.
sl@0	472
sl@0	473	132. 9/14/92 Renamed manual entries to have extensions like .3 and .n,
sl@0	474	and added "install" target to Makefile.
sl@0	475
sl@0	476	133. 9/18/92 Modified "unknown" command to emulate !!, !<num>, and
sl@0	477	^<old>^<new> csh history substitutions.
sl@0	478
sl@0	479	134. 9/21/92 Made the config script cleverer about figuring out which
sl@0	480	switches to pass to "nm".
sl@0	481
sl@0	482	135. 9/23/92 Fixed tclVar.c to be sure to copy flags when growing variables.
sl@0	483	Used to forget about traces in progress and make extra recursive calls
sl@0	484	on trace procs.
sl@0	485
sl@0	486	136. 9/28/92 Fixed bug in auto_reset where it was unsetting variables
sl@0	487	that might not exist.
sl@0	488
sl@0	489	137. 10/7/92 Changed "parray" library procedure to print any array
sl@0	490	accessible to caller, local or global.
sl@0	491
sl@0	492	138. 10/15/92 Fixed bug where propagation of new environment variable
sl@0	493	values among interpreters took N! time if there exist N interpreters.
sl@0	494
sl@0	495	139. 10/16/92 Changed auto_reset procedure so that it also deletes any
sl@0	496	existing procedures that are in the auto_load index (the assumption is
sl@0	497	that they should be re-loaded to get the latest versions).
sl@0	498
sl@0	499	140. 10/21/92 Fixed bug that caused lists to be incorrectly generated
sl@0	500	for elements that contained backslash-newline sequences.
sl@0	501
sl@0	502	141. 12/9/92 Added support for TCL_LIBRARY environment variable: use
sl@0	503	it as library location if it's present.
sl@0	504
sl@0	505	142. 12/9/92 Added "info complete" command, Tcl_CommandComplete procedure.
sl@0	506
sl@0	507	143. 12/16/92 Changed the Makefile to check to make sure "config" has been
sl@0	508	run (can't run config directly from the Makefile because it modifies the
sl@0	509	Makefile; thus make has to be run again after running config).
sl@0	510
sl@0	511	----------------- Released version 6.5, 12/17/92 ------------------
sl@0	512
sl@0	513	144. 12/21/92 Changed config to look in several places for libc file.
sl@0	514
sl@0	515	145. 12/23/92 Added "elseif" support to if. Also, "then", "else", and
sl@0	516	"elseif" may no longer be abbreviated.
sl@0	517	* POTENTIAL INCOMPATIBILITY *
sl@0	518
sl@0	519	146. 12/28/92 Changed "puts" and "read" to support initial "-nonewline"
sl@0	520	switch instead of additional "nonewline" argument. The old form is
sl@0	521	still supported, but it is discouraged and is no longer documented.
sl@0	522	Also changed "puts" to make the file argument default to stdout: e.g.
sl@0	523	"puts foo" will print foo on standard output.
sl@0	524
sl@0	525	147. 1/6/93 Fixed bug whereby backslash-newline wasn't working when
sl@0	526	typed interactively, or in "info complete".
sl@0	527
sl@0	528	148. 1/22/93 Fixed bugs in "lreplace" and "linsert" where close
sl@0	529	quotes were being lost from last element before replacement or
sl@0	530	insertion.
sl@0	531
sl@0	532	149. 1/29/93 Fixed bug in Tcl_AssembleCmd where it wasn't requiring
sl@0	533	a newline at the end of a line before considering a command to be
sl@0	534	complete. The bug caused some very long lines in script files to
sl@0	535	be processed as multiple separate commands.
sl@0	536
sl@0	537	150. 1/29/93 Various changes in Makefile to add more configuration
sl@0	538	options, simplify installation, fix bugs (e.g. don't use -f switch
sl@0	539	for cp), etc.
sl@0	540
sl@0	541	151. 1/29/93 Changed "name1" and "name2" identifiers to "part1" and
sl@0	542	"part2" to avoid name conflicts with stupid C++ implementations that
sl@0	543	use "name1" and "name2" in a reserved way.
sl@0	544
sl@0	545	152. 2/1/93 Added "putenv" procedure to replace the standard system
sl@0	546	version so that it will work correctly with Tcl's environment handling.
sl@0	547
sl@0	548	----------------- Released version 6.6, 2/5/93 ------------------
sl@0	549
sl@0	550	153. 2/10/93 Fixed bugs in config script: missing "endif" in libc loop,
sl@0	551	and tried to use strncasecmp.c instead of strcasecmp.c.
sl@0	552
sl@0	553	154. 2/10/93 Makefile improvements: added RANLIB variable for easier
sl@0	554	Sys-V configuration, added SHELL variable for SGI systems.
sl@0	555
sl@0	556	----------------- Released version 6.7, 2/11/93 ------------------
sl@0	557
sl@0	558	153. 2/6/93 Changes in backslash processing:
sl@0	559	- \Cx, \Mx, \CMx, \e sequences no longer special
sl@0	560	- \<newline> also eats up any space after the newline, replacing
sl@0	561	the whole sequence with a single space character
sl@0	562	- Hex sequences like \x24 are now supported, along with ANSI C's \a.
sl@0	563	- "format" no longer does backslash processing on its format string
sl@0	564	- there is no longer any special meaning to a 0 return value from
sl@0	565	Tcl_Backslash
sl@0	566	- unknown backslash sequences, like (e.g. \*), are replaced with
sl@0	567	the following character (e.g. *), instead of just treating the
sl@0	568	backslash as an ordinary character.
sl@0	569	* POTENTIAL INCOMPATIBILITY *
sl@0	570
sl@0	571	154. 2/6/93 Updated all copyright notices. The meaning hasn't changed
sl@0	572	at all but the wording does a better job of protecting U.C. from
sl@0	573	liability (according to U.C. lawyers, anyway).
sl@0	574
sl@0	575	155. 2/6/93 Changed "regsub" so that it overwrites the result variable
sl@0	576	in all cases, even if there is no match.
sl@0	577	* POTENTIAL INCOMPATIBILITY *
sl@0	578
sl@0	579	156. 2/8/93 Added support for XPG3 %n$ conversion specifiers to "format"
sl@0	580	command.
sl@0	581
sl@0	582	157. 2/17/93 Fixed bug in Tcl_Eval where errors due to infinite
sl@0	583	recursion could result in core dumps.
sl@0	584
sl@0	585	158. 2/17/93 Improved the auto-load mechanism to deal gracefully (i.e.
sl@0	586	return an error) with a situation where a library file that supposedly
sl@0	587	defines a procedure doesn't actually define it.
sl@0	588
sl@0	589	159. 2/17/93 Renamed Tcl_UnixError procedure to Tcl_PosixError, and
sl@0	590	changed errorCode variable usage to use POSIX as keyword instead of
sl@0	591	UNIX.
sl@0	592	* POTENTIAL INCOMPATIBILITY *
sl@0	593
sl@0	594	160. 2/19/93 Changes to exec and process control:
sl@0	595	- Added support for >>, >&, >>&, \|&, <@, >@, and >&@ forms of redirection.
sl@0	596	- When exec puts processes into background, it returns a list of
sl@0	597	their pids as result.
sl@0	598	- Added support for <file, >file, etc. (i.e. no space between
sl@0	599	">" and file name.
sl@0	600	- Added -keepnewline option.
sl@0	601	- Deleted Tcl_Fork and Tcl_WaitPids procedures (just use fork and
sl@0	602	waitpid instead).
sl@0	603	- Added waitpid compatibility procedure for systems that don't have
sl@0	604	it.
sl@0	605	- Added Tcl_ReapDetachedProcs procedure.
sl@0	606	- Changed "exec" to return an error if there is stderr output, even
sl@0	607	if the command returns a 0 exit status (it's always been documented
sl@0	608	this way, but the implementation wasn't correct).
sl@0	609	- If a process returns a non-zero exit status but doesn't generate
sl@0	610	any diagnostic output, then Tcl generates an error message for it.
sl@0	611	* POTENTIAL INCOMPATIBILITY *
sl@0	612
sl@0	613	161. 2/25/93 Fixed two memory-management problems having to do with
sl@0	614	managing the old result during variable trace callbacks.
sl@0	615
sl@0	616	162. 3/1/93 Added dynamic string library: Tcl_DStringInit, Tcl_DStringAppend,
sl@0	617	Tcl_DStringFree, Tcl_DStringResult, etc.
sl@0	618
sl@0	619	163. 3/1/93 Modified glob command to only return the names of files that
sl@0	620	exist, and to only return names ending in "/" if the file is a directory.
sl@0	621	* POTENTIAL INCOMPATIBILITY *
sl@0	622
sl@0	623	164. 3/19/93 Modified not to use system calls like "read" directly,
sl@0	624	but instead to use special Tcl procedures that retry automatically
sl@0	625	if interrupted by signals.
sl@0	626
sl@0	627	165. 4/3/93 Eliminated "noSep" argument to Tcl_AppendElement, plus
sl@0	628	TCL_NO_SPACE flag for Tcl_SetVar and Tcl_SetVar2.
sl@0	629	* POTENTIAL INCOMPATIBILITY *
sl@0	630
sl@0	631	166. 4/3/93 Eliminated "flags" and "termPtr" arguments to Tcl_Eval.
sl@0	632	* POTENTIAL INCOMPATIBILITY *
sl@0	633
sl@0	634	167. 4/3/93 Changes to expressions:
sl@0	635	- The "expr" command now accepts multiple arguments, which are
sl@0	636	concatenated together with space separators.
sl@0	637	- Integers aren't automatically promoted to floating-point if they
sl@0	638	overflow the word size: errors are generated instead.
sl@0	639	- Tcl can now handle "NaN" and other special values if the underlying
sl@0	640	library procedures handle them.
sl@0	641	- When printing floating-point numbers, Tcl ensures that there is a "."
sl@0	642	or "e" in the number, so it can't be treated as an integer accidentally.
sl@0	643	The procedure Tcl_PrintDouble is available to provide this function
sl@0	644	in other contexts. Also, the variable "tcl_precision" can be used
sl@0	645	to set the precision for printing (must be a decimal number giving
sl@0	646	digits of precision).
sl@0	647	- Expressions now support transcendental and other functions, e.g. sin,
sl@0	648	acos, hypot, ceil, and round. Can add new math functions with
sl@0	649	Tcl_CreateMathFunc().
sl@0	650	- Boolean expressions can now have any of the string values accepted
sl@0	651	by Tcl_GetBoolean, such as "yes" or "no".
sl@0	652	* POTENTIAL INCOMPATIBILITY *
sl@0	653
sl@0	654	168. 4/5/93 Changed Tcl_UnsetVar and Tcl_UnsetVar2 to return TCL_OK
sl@0	655	or TCL_ERROR instead of 0 or -1.
sl@0	656	* POTENTIAL INCOMPATIBILITY *
sl@0	657
sl@0	658	169. 4/5/93 Eliminated Tcl_CmdBuf structure and associated procedures;
sl@0	659	can use Tcl_DStrings instead.
sl@0	660	* POTENTIAL INCOMPATIBILITY *
sl@0	661
sl@0	662	170. 4/8/93 Changed interface to Tcl_TildeSubst to use a dynamic
sl@0	663	string for buffer space. This makes the procedure re-entrant and
sl@0	664	thread-safe, whereas it wasn't before.
sl@0	665	* POTENTIAL INCOMPATIBILITY *
sl@0	666
sl@0	667	171. 4/14/93 Eliminated tclHash.h, and moved everything from it to
sl@0	668	tcl.h
sl@0	669	* POTENTIAL INCOMPATIBILITY *
sl@0	670
sl@0	671	172. 4/15/93 Eliminated Tcl_InitHistory, made "history" command always
sl@0	672	be part of interpreter.
sl@0	673	* POTENTIAL INCOMPATIBILITY *
sl@0	674
sl@0	675	173. 4/16/93 Modified "file" command so that "readable" option always
sl@0	676	exists, even on machines that don't support symbolic links (always returns
sl@0	677	same error as if the file wasn't a symbolic link).
sl@0	678
sl@0	679	174. 4/26/93 Fixed bugs in "regsub" where ^ patterns didn't get handled
sl@0	680	right (pretended not to match when it really did, and looped infinitely
sl@0	681	if -all was specified).
sl@0	682
sl@0	683	175. 4/29/93 Various improvements in the handling of variables:
sl@0	684	- Can create variables and array elements during a read trace.
sl@0	685	- Can delete variables during traces (note: unset traces will be
sl@0	686	invoked when this happens).
sl@0	687	- Can upvar to array elements.
sl@0	688	- Can retarget an upvar to another variable by re-issuing the
sl@0	689	upvar command with a different "other" variable.
sl@0	690
sl@0	691	176. 5/3/93 Added Tcl_GetCommandInfo, which returns info about a Tcl
sl@0	692	command such as whether it exists and its ClientData. Also added
sl@0	693	Tcl_SetCommandInfo, which allows any of this information to be modified
sl@0	694	and also allows a command's delete procedure to have a different
sl@0	695	ClientData value than its command procedure.
sl@0	696
sl@0	697	177. 5/5/93 Added Tcl_RegExpMatch procedure.
sl@0	698
sl@0	699	178. 5/6/93 Fixed bug in "scan" where it didn't properly handle
sl@0	700	%% conversion specifiers. Also changed "scan" to use Tcl_PrintDouble
sl@0	701	for printing real values.
sl@0	702
sl@0	703	179. 5/7/93 Added "-exact", "-glob", and "-regexp" options to "lsearch"
sl@0	704	command to allow different kinds of pattern matching.
sl@0	705
sl@0	706	180. 5/7/93 Added many new switches to "lsort" to control the sorting
sl@0	707	process: "-ascii", "-integer", "-real", "-command", "-increasing",
sl@0	708	and "-decreasing".
sl@0	709
sl@0	710	181. 5/10/93 Changes to file I/O:
sl@0	711	- Modified "open" command to support a list of POSIX access flags
sl@0	712	like {WRONLY CREAT TRUNC} in addition to current fopen-style
sl@0	713	access modes. Also added "permissions" argument to set permissions
sl@0	714	of newly-created files.
sl@0	715	- Fixed Scott Bolte's bug (can close stdin etc. in application and
sl@0	716	then re-open them with Tcl commands).
sl@0	717	- Exported access to Tcl's file table with new procedures Tcl_EnterFile
sl@0	718	and Tcl_GetOpenFile.
sl@0	719
sl@0	720	182. 5/15/93 Added new "pid" command, which can be used to retrieve
sl@0	721	either the current process id or a list of the process ids in a
sl@0	722	pipeline opened with "open \|..."
sl@0	723
sl@0	724	183. 6/3/93 Changed to use GNU autoconfig for configuration instead of
sl@0	725	the home-brew "config" script. Also made many other configuration-related
sl@0	726	changes, such as using <unistd.h> instead of explicitly declaring system
sl@0	727	calls in tclUnix.h.
sl@0	728
sl@0	729	184. 6/4/93 Fixed bug where core-dumps could occur if a procedure
sl@0	730	redefined itself (the memory for the procedure's body could get
sl@0	731	reallocated in the middle of evaluating the body); implemented
sl@0	732	simple reference count mechanism.
sl@0	733
sl@0	734	185. 6/5/93 Changed tclIndex file format in two ways: (a) it's now
sl@0	735	eval-ed instead of parsed, which makes it 3-4x faster; (b) the entries
sl@0	736	in auto_index are now commands to evaluate, which allows commands to
sl@0	737	be loaded in different ways such as dynamic-loading of C code. The
sl@0	738	old tclIndex file format is still supported.
sl@0	739
sl@0	740	186. 6/7/93 Eliminated tclTest program, added new "tclsh" program
sl@0	741	that is more like wish (allows script files to be invoked automatically
sl@0	742	using "#!/usr/local/bin/tclsh", makes arguments available to script,
sl@0	743	etc.). Added support for Tcl_AppInit plus default version; this
sl@0	744	allows new Tcl applications to be created without modifying the
sl@0	745	main program for tclsh.
sl@0	746
sl@0	747	187. 6/7/93 Fixed bug in TclWordEnd that kept backslash-newline from
sl@0	748	working correctly in some cases during interactive input.
sl@0	749
sl@0	750	188. 6/9/93 Added Tcl_LinkVar and related procedures, which automatically
sl@0	751	keep a Tcl variable in sync with a C variable.
sl@0	752
sl@0	753	189. 6/16/93 Increased maximum nesting depth from 100 to 1000.
sl@0	754
sl@0	755	190. 6/16/93 Modified "trace var" command so that error messages from
sl@0	756	within traces are returned properly as the result of the variable
sl@0	757	access, instead of the generic "access disallowed by trace command"
sl@0	758	message.
sl@0	759
sl@0	760	191. 6/16/93 Added Tcl_CallWhenDeleted to provide callbacks when an
sl@0	761	interpreter is deleted (same functionality as Tcl_WatchInterp, which
sl@0	762	used to exist in versions before 6.0).
sl@0	763
sl@0	764	193. 6/16/93 Added "-code" argument to "return" command; it's there
sl@0	765	primarily for completeness, so that procedures implementing control
sl@0	766	constructs can reflect exceptional conditions back to their callers.
sl@0	767
sl@0	768	194. 6/16/93 Split up Tcl.n to make separate manual entries for each
sl@0	769	Tcl command. Tcl.n now contains a summary of the language syntax.
sl@0	770
sl@0	771	195. 6/17/93 Added new "switch" command to replace "case": allows
sl@0	772	alternate forms of pattern matching (exact, glob, regexp), replaces
sl@0	773	pattern lists with single patterns (but you can use "-" bodies to
sl@0	774	share one body among several patterns), eliminates "in" noise word.
sl@0	775	"Case" command is now obsolete.
sl@0	776
sl@0	777	196. 6/17/93 Changed the "exec", "glob", "regexp", and "regsub" commands
sl@0	778	to include a "--" switch. All initial arguments starting with "-" are now
sl@0	779	treated as switches unless a "--" switch is present to end the list.
sl@0	780	* POTENTIAL INCOMPATIBILITY *
sl@0	781
sl@0	782	197. 6/17/93 Changed auto-exec so that the subprocess gets stdin, stdout,
sl@0	783	and stderr from the parent. This allows truly interactive sub-processes
sl@0	784	(e.g. vi) to be auto-exec'ed from a tcl shell command line.
sl@0	785
sl@0	786	198. 6/18/93 Added patchlevel.h, for use in coordinating future patch
sl@0	787	releases, and also added "info patchlevel" command to make the patch
sl@0	788	level available to Tcl scripts.
sl@0	789
sl@0	790	199. 6/19/93 Modified "glob" command so that a leading "//" in a name
sl@0	791	gets left as is (this is needed for systems like Apollos where "//" is
sl@0	792	the super-root; Tcl used to collapse the two slashes into a single
sl@0	793	slash).
sl@0	794
sl@0	795	200. 7/7/93 Added Tcl_SetRecursionLimit procedure so that the maximum
sl@0	796	allowable nesting depth can be controlled for an interpreter from C.
sl@0	797
sl@0	798	----------------- Released version 7.0 Beta 1, 7/9/93 ------------------
sl@0	799
sl@0	800	201. 7/12/93 Modified Tcl_GetInt and tclExpr.c so that full-precision
sl@0	801	unsigned integers can be specified without overflow errors.
sl@0	802
sl@0	803	202. 7/12/93 Configuration changes: eliminate leading blank line in
sl@0	804	configure script; provide separate targets in Makefile for installing
sl@0	805	binary and non-binary information; check for size_t and a few other
sl@0	806	potentially missing typedefs; don't put tclAppInit.o into libtcl.a;
sl@0	807	better checks for matherr support.
sl@0	808
sl@0	809	203. 7/14/93 Changed tclExpr.c to check the termination pointer before
sl@0	810	errno after strtod calls, to avoid problems with some versions of
sl@0	811	strtod that set errno in unexpected ways.
sl@0	812
sl@0	813	204. 7/16/93 Changed "scan" command to be more ANSI-conformant:
sl@0	814	eliminated %F, %D, etc., added code to ignore "l", "h", and "L"
sl@0	815	modifiers but always convert %e, %f, and %g with implicit "l";
sl@0	816	also added support for %u and %i. Also changed "format" command
sl@0	817	to eliminate %D, %U, %O, and add %i.
sl@0	818	* POTENTIAL INCOMPATIBILITY *
sl@0	819
sl@0	820	205. 7/17/93 Changed "uplevel" and "upvar" so that they can be used
sl@0	821	from global level to global level: this used to generate an error.
sl@0	822
sl@0	823	206. 7/19/93 Renamed "setenv", "putenv", and "unsetenv" procedures
sl@0	824	to avoid conflicts with system procedures with the same names. If
sl@0	825	you want Tcl's procedures to override the system procedures, do it
sl@0	826	in the Makefile (instructions are in the Makefile).
sl@0	827	* POTENTIAL INCOMPATIBILITY *
sl@0	828
sl@0	829	----------------- Released version 7.0 Beta 2, 7/21/93 ------------------
sl@0	830
sl@0	831	207. 7/21/93 Fixed bug in tclVar.c where freed memory was accidentally
sl@0	832	used if a procedure returned an element of a local array.
sl@0	833
sl@0	834	208. 7/22/93 Fixed bug in "unknown" where it didn't properly handle
sl@0	835	errors occurring in the "auto_load" procedure, leaving its state
sl@0	836	inconsistent.
sl@0	837
sl@0	838	209. 7/23/93 Changed exec's ">2" redirection operator to "2>" for
sl@0	839	consistency with sh. This is incompatible with earlier beta releases
sl@0	840	of 7.0 but not with pre-7.0 releases, which didn't support either
sl@0	841	operator.
sl@0	842
sl@0	843	210. 7/28/93 Changed backslash-newline handling so that the resulting
sl@0	844	space character is treated as a word separator unless the backslash
sl@0	845	sequence is in quotes or braces. This is incompatible with 7.0b1
sl@0	846	and 7.0b2 but is more compatible with pre-7.0 versions that the b1
sl@0	847	and b2 releases were.
sl@0	848
sl@0	849	211. 7/28/93 Eliminated Tcl_LinkedVarWritable, added TCL_LINK_READ_ONLY to
sl@0	850	Tcl_LinkVar to accomplish same purpose. This change is incompatible
sl@0	851	with earlier beta releases, but not with releases before Tcl 7.0.
sl@0	852
sl@0	853	212. 7/29/93 Renamed regexp C functions so they won't clash with POSIX
sl@0	854	regexp functions that use the same name.
sl@0	855
sl@0	856	213. 8/3/93 Added "-errorinfo" and "-errorcode" options to "return"
sl@0	857	command: these allow for much better handling of the errorInfo
sl@0	858	and errorCode variables in some cases.
sl@0	859
sl@0	860	214. 8/12/93 Changed "expr" so that % always returns a remainder with
sl@0	861	the same sign as the divisor and absolute value smaller than the
sl@0	862	divisor.
sl@0	863
sl@0	864	215. 8/14/93 Turned off auto-exec in "unknown" unless the command
sl@0	865	was typed interactively. This means you must use "exec" when
sl@0	866	invoking subprocesses, unless it's a command that's typed interactively.
sl@0	867	* POTENTIAL INCOMPATIBILITY *
sl@0	868
sl@0	869	216. 8/14/93 Added support for tcl_prompt1 and tcl_prompt2 variables
sl@0	870	to tclMain.c: makes prompts user-settable.
sl@0	871
sl@0	872	217. 8/14/93 Added asynchronous handlers (Tcl_AsyncCreate etc.) so
sl@0	873	that signals can be taken cleanly by Tcl applications.
sl@0	874
sl@0	875	218. 8/16/93 Moved information about open files from the interpreter
sl@0	876	structure to global variables so that a file can be opened in one
sl@0	877	interpreter and read or written in another.
sl@0	878
sl@0	879	219. 8/16/93 Removed ENV_FLAGS from Makefile, so that there's no
sl@0	880	official support for overriding setenv, unsetenv, and putenv.
sl@0	881
sl@0	882	220. 8/20/93 Various configuration improvements: coerce chars
sl@0	883	to unsigned chars before using macros like isspace; source ~/.tclshrc
sl@0	884	file during initialization if it exists and program is running
sl@0	885	interactively; allow there to be directories in auto_path that don't
sl@0	886	exist or don't have tclIndex files (ignore them); added Tcl_Init
sl@0	887	procedure and changed Tcl_AppInit to call it.
sl@0	888
sl@0	889	221. 8/21/93 Fixed bug in expr where "+", "-", and " " were all
sl@0	890	getting treated as integers with value 0.
sl@0	891
sl@0	892	222. 8/26/93 Added "tcl_interactive" variable to tclsh.
sl@0	893
sl@0	894	223. 8/27/93 Added procedure Tcl_FilePermissions to return whether a
sl@0	895	given file can be read or written or both. Modified Tcl_EnterFile
sl@0	896	to take a permissions mask rather than separate read and write arguments.
sl@0	897
sl@0	898	224. 8/28/93 Fixed performance bug in "glob" command (unnecessary call
sl@0	899	to "access" for each file caused a 5-10x slow-down for big directories).
sl@0	900
sl@0	901	----------------- Released version 7.0 Beta 3, 8/28/93 ------------------
sl@0	902
sl@0	903	225. 9/9/93 Renamed regexp.h to tclRegexp.h to avoid conflicts with system
sl@0	904	include file by same name.
sl@0	905
sl@0	906	226. 9/9/93 Added Tcl_DontCallWhenDeleted.
sl@0	907
sl@0	908	227. 9/16/93 Changed not to call exit C procedure directly; instead
sl@0	909	always invoke "exit" Tcl command so that application can redefine the
sl@0	910	command to do additional cleanup.
sl@0	911
sl@0	912	228. 9/17/93 Changed auto-exec to handle names that contain slashes
sl@0	913	(i.e. don't use PATH for them).
sl@0	914
sl@0	915	229. 9/23/93 Fixed bug in "read" and "gets" commands where they didn't
sl@0	916	clear EOF conditions.
sl@0	917
sl@0	918	----------------- Released version 7.0, 9/29/93 ------------------
sl@0	919
sl@0	920	230. 10/7/93 "Scan" command wasn't properly aligning things in memory,
sl@0	921	so segmentation faults could arise under some circumstances.
sl@0	922
sl@0	923	231. 10/7/93 Fixed bug in Tcl_ConvertElement where it forgot to
sl@0	924	backslash leading curly brace when creating lists.
sl@0	925
sl@0	926	232. 10/7/93 Eliminated dependency of tclMain.c on tclInt.h and
sl@0	927	tclUnix.h, so that people can copy the file out of the Tcl source
sl@0	928	directory to make modified private versions.
sl@0	929
sl@0	930	233. 10/8/93 Fixed bug in auto-loader that reversed the priority order
sl@0	931	of entries in auto_path for new-style index files. Now things are
sl@0	932	back to the way they were before 3.0: first in auto_path is always
sl@0	933	highest priority.
sl@0	934
sl@0	935	234. 10/13/93 Fixed bug where Tcl_CommandComplete didn't recognize
sl@0	936	comments and treat them as such. Thus if you typed the line
sl@0	937	# {
sl@0	938	interactively, Tcl would think that the command wasn't complete and
sl@0	939	wait for more input before evaluating the script.
sl@0	940
sl@0	941	235. 10/14/93 Fixed bug where "regsub" didn't set the output variable
sl@0	942	if the input string was empty.
sl@0	943
sl@0	944	236. 10/23/93 Fixed bug where Tcl_CreatePipeline didn't close off enough
sl@0	945	file descriptors in child processes, causing children not to exit
sl@0	946	properly in some cases.
sl@0	947
sl@0	948	237. 10/28/93 Changed "list" and "concat" commands not to generate
sl@0	949	errors if given zero arguments, but instead to just return an empty
sl@0	950	string.
sl@0	951
sl@0	952	----------------- Released version 7.1, 11/4/93 ------------------
sl@0	953
sl@0	954	Note: there is no 7.2 release. It was flawed and was thus withdrawn
sl@0	955	shortly after it was released.
sl@0	956
sl@0	957	238. 11/10/93 TclMain.c didn't compile on some systems because of
sl@0	958	R_OK in call to "access". Changed to eliminate call to "access".
sl@0	959
sl@0	960	----------------- Released version 7.3, 11/26/93 ------------------
sl@0	961
sl@0	962	239. 11/6/93 Modified "lindex", "linsert", "lrange", and "lreplace"
sl@0	963	so that "end" can be specified as an index.
sl@0	964
sl@0	965	240. 11/6/93 Modified "append" and "lappend" to allow only two
sl@0	966	words total (i.e., nothing to append) without generating an error.
sl@0	967
sl@0	968	241. 12/2/93 Changed to use EAGAIN as the errno for non-blocking
sl@0	969	I/O instead of EWOULDBLOCK: this should fix problem where non-blocking
sl@0	970	I/O didn't work correctly on System-V systems.
sl@0	971
sl@0	972	242. 12/22/93 Fixed bug in expressions where cancelled evaluation
sl@0	973	wasn't always working correctly (e.g. "set one 1; eval {1 \|\| 1/$one}"
sl@0	974	failed with a divide by zero error).
sl@0	975
sl@0	976	243. 1/6/94 Changed TCL_VOLATILE definition from -1 to the address of
sl@0	977	a dummy procedure Tcl_Volatile, since -1 causes portability problems on
sl@0	978	some machines (e.g., Crays).
sl@0	979
sl@0	980	244. 2/4/94 Added support for unary plus.
sl@0	981
sl@0	982	245. 2/17/94 Changed Tcl_RecordAndEval and "history" command to
sl@0	983	call Tcl_GlobalEval instead of Tcl_Eval. Otherwise, invocation of
sl@0	984	these facilities in nested procedures can cause unwanted results.
sl@0	985
sl@0	986	246. 2/17/94 Fixed bug in tclExpr.c where an expression such as
sl@0	987	"expr {"12398712938788234-1298379" != ""}" triggers an integer
sl@0	988	overflow error for the number in quotes, even though it isn't really
sl@0	989	a proper integer anyway.
sl@0	990
sl@0	991	247. 2/19/94 Added new procedure Tcl_DStringGetResult to move result
sl@0	992	from interpreter to a dynamic string.
sl@0	993
sl@0	994	248. 2/19/94 Fixed bug in Tcl_DStringResult that caused it to overwrite
sl@0	995	the contents of a static result in some situations. This can cause
sl@0	996	bizarre errors such as variables suddenly having empty values.
sl@0	997
sl@0	998	249. 2/21/94 Fixed bug in Tcl_AppendElement, Tcl_DStringAppendElement,
sl@0	999	and the "lappend" command that caused improper omission of a separator
sl@0	1000	space in some cases. For example, the script
sl@0	1001	set x "abc{"; lappend x "def"
sl@0	1002	used to return the result "abc{def" instead of "abc{ def".
sl@0	1003
sl@0	1004	250. 3/3/94 Tcl_ConvertElement was outputting empty elements as \0 if
sl@0	1005	TCL_DONT_USE_BRACES was set. This depends on old pre-7.0 meaning of
sl@0	1006	\0, which is no longer in effect, so it didn't really work. Changed
sl@0	1007	to output empty elements as {} always.
sl@0	1008
sl@0	1009	251. 3/3/94 Renamed Tcl_DStringTrunc to Tcl_DStringSetLength and extended
sl@0	1010	it so that it can be used to lengthen a string as well as shorten it.
sl@0	1011	Tcl_DStringTrunc is defined as a macro for backward compatibility, but
sl@0	1012	it is deprecated.
sl@0	1013
sl@0	1014	252. 3/3/94 Added Tcl_AllowExceptions procedure.
sl@0	1015
sl@0	1016	253. 3/13/94 Fixed bug in Tcl_FormatCmd that could cause "format"
sl@0	1017	to mis-behave on 64-bit Big-Endian machines.
sl@0	1018
sl@0	1019	254. 3/13/94 Changed to use vfork instead of fork on systems where
sl@0	1020	vfork exists.
sl@0	1021
sl@0	1022	255. 3/23/94 Fixed bug in expressions where ?: didn't associate
sl@0	1023	right-to-left as they should.
sl@0	1024
sl@0	1025	256. 4/3/94 Fixed "exec" to flush any files used in >@ or >&@
sl@0	1026	redirection in exec, so that data buffered for them is written
sl@0	1027	before any new data added by the subprocess.
sl@0	1028
sl@0	1029	257. 4/3/94 Added "subst" command.
sl@0	1030
sl@0	1031	258. 5/20/94 The tclsh main program is now called Tcl_Main; tclAppInit.c
sl@0	1032	has a "main" procedure that calls Tcl_Main. This makes it easier to use
sl@0	1033	Tcl with C++ programs, which need their own main programs, and it also
sl@0	1034	allows an application to prefilter the argument list before calling
sl@0	1035	Tcl_Main.
sl@0	1036	* POTENTIAL INCOMPATIBILITY *
sl@0	1037
sl@0	1038	259. 6/6/94 Fixed bug in procedure returns where the errorInfo variable
sl@0	1039	could get truncated if an unset trace was invoked as part of returning
sl@0	1040	from the procedure.
sl@0	1041
sl@0	1042	260. 6/13/94 Added "wordstart" and "wordend" options to "string" command.
sl@0	1043
sl@0	1044	261. 6/27/94 Fixed bug in expressions where they didn't properly cancel
sl@0	1045	the evaluation of math functions in &&, \|\|, and ?:.
sl@0	1046
sl@0	1047	262. 7/11/94 Incorrect boolean values, like "ogle", weren't being
sl@0	1048	handled properly.
sl@0	1049
sl@0	1050	263. 7/15/94 Added Tcl_RegExpCompile, Tcl_RegExpExec, and Tcl_RegExpRange,
sl@0	1051	which provide lower-level access to regular expression pattern matching.
sl@0	1052
sl@0	1053	264. 7/22/94 Fixed bug in "glob" command where "glob -nocomplain ~bad_user"
sl@0	1054	would complain about a missing user. Now it doesn't complain anymore.
sl@0	1055
sl@0	1056	265. 8/4/94 Fixed bug with linked variables where they didn't behave
sl@0	1057	correctly when accessed via upvars.
sl@0	1058
sl@0	1059	266. 8/17/94 Fixed bug in Tcl_EvalFile where it didn't clear interp->result.
sl@0	1060
sl@0	1061	267. 8/31/94 Modified "open" command so that errors in exec-ing
sl@0	1062	subprocesses are returned by the open immediately, rather than
sl@0	1063	being delayed until the "close" is executed.
sl@0	1064
sl@0	1065	268. 9/9/94 Modified "expr" command to generate errors for integer
sl@0	1066	overflow (includes addition, subtraction, negation, multiplication,
sl@0	1067	division).
sl@0	1068
sl@0	1069	269. 9/23/94 Modified "regsub" to return a count of the number of
sl@0	1070	matches and replacements, rather than 0/1.
sl@0	1071
sl@0	1072	279. 10/4/94 Added new features to "array" command:
sl@0	1073	- added "get" and "set" commands for easy conversion between arrays
sl@0	1074	and lists.
sl@0	1075	- added "exists" command to see if a variable is an array, changed
sl@0	1076	"names" and "size" commands to treat a non-existent array (or scalar
sl@0	1077	variable) just like an empty one.
sl@0	1078	- added pattern option to "names" command.
sl@0	1079
sl@0	1080	280. 10/6/94 Modified Tcl_SetVar2 so that read traces on variables get
sl@0	1081	called during append operations.
sl@0	1082
sl@0	1083	281. 10/20/94 Fixed bug in "read" command where reading from stdin
sl@0	1084	required two control-D's to stop the reading.
sl@0	1085
sl@0	1086	282. 11/3/94 Changed "expr" command to use longs for division just like
sl@0	1087	all other expr operators; it previously used ints for division.
sl@0	1088
sl@0	1089	283. 11/4/94 Fixed bugs in "unknown" procedure: it wasn't properly
sl@0	1090	handling exception returns from commands that were executed after
sl@0	1091	being auto-loaded.
sl@0	1092
sl@0	1093	----------------- Released version 7.4b1, 12/23/94 ------------------
sl@0	1094
sl@0	1095	284. 12/26/94 Fixed "install" target in Makefile (couldn't always
sl@0	1096	find install program).
sl@0	1097
sl@0	1098	285. 12/26/94 Added strcncasecmp procedure to compat directory.
sl@0	1099
sl@0	1100	286. 1/3/95 Fixed all procedure calls to explicitly cast arguments:
sl@0	1101	implicit conversions from prototypes (especially integer->double)
sl@0	1102	don't work when compiling under non-ANSI compilers. Tcl is now clean
sl@0	1103	under gcc -Wconversion.
sl@0	1104
sl@0	1105	287. 1/4/95 Fixed problem in Tcl_ArrayCmd where same name was used for
sl@0	1106	both a label and a variable; caused problems on several older compilers,
sl@0	1107	making array command misbehave and causing many errors in Tcl test suite.
sl@0	1108
sl@0	1109	----------------- Released version 7.4b2, 1/12/95 ------------------
sl@0	1110
sl@0	1111	288. 2/9/95 Modified Tcl_CreateCommand to return a token, and added
sl@0	1112	Tcl_GetCommandName procedure. Together, these procedures make it possible
sl@0	1113	to track renames of a command.
sl@0	1114
sl@0	1115	289. 2/13/95 Fixed bug in expr where "089" was interpreted as a
sl@0	1116	floating-point number rather than a bogus octal number.
sl@0	1117	* POTENTIAL INCOMPATIBILITY *
sl@0	1118
sl@0	1119	290. 2/14/95 Added code to Tcl_GetInt and Tcl_GetDouble to check for
sl@0	1120	overflows when reading in numbers.
sl@0	1121
sl@0	1122	291. 2/18/95 Changed "array set" to stop after first error, rather than
sl@0	1123	continuing after error.
sl@0	1124
sl@0	1125	292. 2/20/95 Upgraded to use autoconf version 2.2.
sl@0	1126
sl@0	1127	293. 2/20/95 Fixed core dump that could occur in "scan" command if a
sl@0	1128	close bracket was omitted.
sl@0	1129
sl@0	1130	294. 2/27/95 Changed Makefile to always use install-sh for installations:
sl@0	1131	there's just too much variation among "install" system programs, which
sl@0	1132	makes installation flakey.
sl@0	1133
sl@0	1134	----------------- Released version 7.4b3, 3/24/95 ------------------
sl@0	1135
sl@0	1136	3/25/95 (bug fix) Changed "install" to "./install" in Makefile so that
sl@0	1137	"make install" will work even when "." isn't in the search path.
sl@0	1138
sl@0	1139	3/29/95 (bug fix) Fixed bug where the auto-loading mechanism wasn't
sl@0	1140	protecting the values of the errorCode and errorInfo variables.
sl@0	1141
sl@0	1142	3/29/95 (new feature) Added optional pattern argument to "parray" procedure.
sl@0	1143
sl@0	1144	3/29/95 (bug fix) Made the full functionality of
sl@0	1145	"return -code ... -errorcode ..."
sl@0	1146	work not just inside procedures, but also in sourced files and at
sl@0	1147	top level.
sl@0	1148
sl@0	1149	4/6/95 (new feature) Added "pattern" option to "array names" command.
sl@0	1150
sl@0	1151	4/18/95 (bug fix) Fixed bug in parser where it didn't allow backslash-newline
sl@0	1152	immediately after an argument in braces or quotes.
sl@0	1153
sl@0	1154	4/19/95 (new feature) Added tcl_library variable, which application can
sl@0	1155	set to override default library directory.
sl@0	1156
sl@0	1157	4/30/95 (bug fix) During trace callbacks for array elements, the variable
sl@0	1158	name used in the original reference would be temporarily modified to
sl@0	1159	separate the array name and element name; if the trace callback used
sl@0	1160	the same name string, it would get the wrong name (the array name without
sl@0	1161	element). Fixed to restore the variable name before making trace
sl@0	1162	callbacks.
sl@0	1163
sl@0	1164	4/30/95 (new feature) Added -nobackslashes, -nocommands, and -novariables
sl@0	1165	switches to "subst" command.
sl@0	1166
sl@0	1167	5/4/95 (new feature) Added TCL_EVAL_GLOBAL flag to Tcl_RecordAndEval.
sl@0	1168
sl@0	1169	5/5/95 (bug fix) Format command would overrun memory when printing
sl@0	1170	integers with very large precision, as in "format %.1000d 0".
sl@0	1171
sl@0	1172	5/5/95 (portability improvement) Changed to use BSDgettimeofday on
sl@0	1173	IRIX machines, to avoid compilation problems with the gettimeofday
sl@0	1174	declaration.
sl@0	1175
sl@0	1176	5/6/95 (bug fix) Changed manual entries to use the standard .TH
sl@0	1177	macro instead of a custom .HS macro; the .HS macro confuses index
sl@0	1178	generators like makewhatis.
sl@0	1179
sl@0	1180	5/9/95 (bug fix) Modified configure script to check for Solaris bug
sl@0	1181	that makes vfork unreliable (core dumps result if vforked child
sl@0	1182	changes a signal handler); will use fork instead of vfork if the
sl@0	1183	bug is present.
sl@0	1184
sl@0	1185	6/5/95 (bug fix) Modified "lsort" command to disallow recursive calls
sl@0	1186	to lsort from a comparison function. This is needed because qsort
sl@0	1187	is not reentrant.
sl@0	1188
sl@0	1189	6/5/95 (bug fix) Undid change 243 above: changed TCL_VOLATILE and
sl@0	1190	TCL_DYNAMIC back to integer constants rather than procedure addresses.
sl@0	1191	This was needed because procedure addresses can have multiple values
sl@0	1192	under some dynamic loading systems (e.g. SunOS 4.1 and Windows).
sl@0	1193
sl@0	1194	6/8/95 (feature change) Modified interface to Tcl_Main to pass in the
sl@0	1195	address of the application-specific initialization procedure.
sl@0	1196	Tcl_AppInit is no longer hardwired into Tcl_Main. This is needed
sl@0	1197	in order to make Tcl a shared library.
sl@0	1198
sl@0	1199	6/8/95 (feature change) Modified Makefile so that the installed versions
sl@0	1200	of tclsh and libtcl.a have version number in them (e.g. tclsh7.4 and
sl@0	1201	libtcl7.4.a) and the library directory name also has an embedded version
sl@0	1202	number (e.g., /usr/local/lib/tcl7.4). This should make it easier for
sl@0	1203	Tcl 7.4 to coexist with earlier versions.
sl@0	1204
sl@0	1205	----------------- Released version 7.4b4, 6/16/95 ------------------
sl@0	1206
sl@0	1207	6/19/95 (bug fix) Fixed bugs in tclCkalloc.c that caused core dumps
sl@0	1208	if TCL_MEM_DEBUG was enabled on word-addressed machines such as Crays.
sl@0	1209
sl@0	1210	6/21/95 (feature removal) Removed overflow checks for integer arithmetic:
sl@0	1211	they just cause too much trouble (e.g. for random number generators).
sl@0	1212
sl@0	1213	6/28/95 (new features) Added tcl_patchLevel and tcl_version variables,
sl@0	1214	for consistency with Tk.
sl@0	1215
sl@0	1216	6/29/95 (bug fix) Fixed problem in Tcl_Eval where it didn't record
sl@0	1217	the right termination character if a script ended with a comment. This
sl@0	1218	caused erroneous output for the following command, among others:
sl@0	1219	puts "[
sl@0	1220	expr 1+1
sl@0	1221	# duh!
sl@0	1222	]"
sl@0	1223
sl@0	1224	6/29/95 (message change) Changed the error message for ECHILD slightly
sl@0	1225	to provide a hint about why the problem is occurring.
sl@0	1226
sl@0	1227	----------------- Released version 7.4, 7/1/95 ------------------
sl@0	1228
sl@0	1229	7/18/95 (bug fix) Changed "lreplace" so that nothing is deleted if
sl@0	1230	the last index is less than the first index or if the last index
sl@0	1231	is < 0.
sl@0	1232
sl@0	1233	7/18/95 (bug fix) Fixed bugs with backslashes in comments:
sl@0	1234	Tcl_CommandComplete (and "info complete") didn't properly handle
sl@0	1235	strings ending in backslash-newline, and neither Tcl_CommandComplete
sl@0	1236	nor the Tcl parser handled other backslash sequences right, such
sl@0	1237	as two backslashes before a newline.
sl@0	1238
sl@0	1239	7/19/95 (bug fix) Modified Tcl_DeleteCommand to delete the hash table
sl@0	1240	entry for the command before invoking its callback. This is needed in
sl@0	1241	order to deal with reentrancy.
sl@0	1242
sl@0	1243	7/22/95 (bug fix) "exec" wasn't reaping processes correctly after
sl@0	1244	certain errors (e.g. if the name of the executable was bogus, as
sl@0	1245	in "exec foobar").
sl@0	1246
sl@0	1247	7/27/95 (bug fix) Makefile.in wasn't using the LIBS variable provided
sl@0	1248	by the "configure" script. This caused problems on some SCO systems.
sl@0	1249
sl@0	1250	7/27/95 (bug fix) The version of strtod in fixstrtod.c didn't properly
sl@0	1251	handle the case where endPtr == NULL.
sl@0	1252
sl@0	1253	----------------- Released patch 7.4p1, 7/29/95 -----------------------
sl@0	1254
sl@0	1255	8/4/95 (bug fix) C-level trace callbacks for variables were sometimes
sl@0	1256	receiving the PART1_NOT_PARSED flag, which could cause errors in
sl@0	1257	subsequent Tcl library calls using the flags. (JO)
sl@0	1258
sl@0	1259	8/4/95 (bug fix) Calls to toupper and tolower weren't using the
sl@0	1260	UCHAR macros, which caused trouble in non-U.S. locales. (JO)
sl@0	1261
sl@0	1262	8/10/95 (new feature) Added the "load" command for dynamic loading of
sl@0	1263	binary packages, and the Tcl_PackageInitProc prototype for package
sl@0	1264	initialization procedures. (JO)
sl@0	1265
sl@0	1266	8/23/95 (new features) Added "info sharedlibextension" and
sl@0	1267	"info nameofexecutable" commands, plus Tcl_FindExtension procedure. (JO)
sl@0	1268
sl@0	1269	8/25/95 (bug fix) If the target of an "upvar" was non-existent but
sl@0	1270	had traces set, the traces were silently lost. Change to generate
sl@0	1271	an error instead. (JO)
sl@0	1272
sl@0	1273	8/25/95 (bug fix) Undid change from 7/19, so that commands can stay
sl@0	1274	around while their deletion callbacks execute. Added lots of code to
sl@0	1275	handle all of the reentrancy problems that this opens up. (JO)
sl@0	1276
sl@0	1277	8/25/95 (bug fix) Fixed core dump that could occur in TclDeleteVars
sl@0	1278	if there was an upvar from one entry in the table to the next entry
sl@0	1279	in the same table. (JO)
sl@0	1280
sl@0	1281	8/28/95 (bug fix) Exec wasn't handling bad user names properly, as
sl@0	1282	in "exec ~bogus_user/foo". (JO)
sl@0	1283
sl@0	1284	8/29/95 (bug fixes) Changed backslash-newline handling to correct two
sl@0	1285	problems:
sl@0	1286	- Only spaces and tabs following the backslash-newline are now
sl@0	1287	absorbed as part of the backslash-newline. Newlinew are no
sl@0	1288	longer absorbed (add another backslash if you want to absorb
sl@0	1289	another newline).
sl@0	1290	- TclWordEnd returns the character just before the backslash in
sl@0	1291	the sequence as the end of the sequence; it used to not consider
sl@0	1292	the backslash-newline as a word separator. (JO)
sl@0	1293
sl@0	1294	8/31/95 (new feature) Changed man page installation (with "mkLinks"
sl@0	1295	script) to create additional links for manual pages corresponding to
sl@0	1296	each of the procedure and command names described in the pages. (JO)
sl@0	1297
sl@0	1298	9/10/95 Reorganized Tcl sources for Windows and Mac ports. All sources
sl@0	1299	are now in subdirectories: "generic" contains sources that work on all
sl@0	1300	platforms, "windows", "mac", and "unix" directories contain platform-
sl@0	1301	specific sources. Some UNIX sources are also used on other platforms. (SS)
sl@0	1302
sl@0	1303	9/10/95 (feature change) Eliminated exported global variables (they
sl@0	1304	don't work with Windows DLLs). Replaced tcl_AsyncReady and
sl@0	1305	tcl_FileCloseProc with procedures Tcl_AsyncReady() and
sl@0	1306	Tcl_SetFileCloseProc(). Replaced C variable tcl_RcFileName with
sl@0	1307	a Tcl variable tcl_rcFileName. (SS)
sl@0	1308	* POTENTIAL INCOMPATIBILITY *
sl@0	1309
sl@0	1310	9/11/95 (new feature) Added procedure Tcl_SetPanicProc to override
sl@0	1311	the default implementation of "panic". (SS)
sl@0	1312
sl@0	1313	9/11/95 (new feature) Added "interp" command to allow creation of
sl@0	1314	new interpreters and execution of untrusted scripts. Added many new
sl@0	1315	procedures, such as Tcl_CreateSlave, Tcl_CreateAlias,and Tcl_MakeSafe,
sl@0	1316	to provide C-level access to the interpreter facility. This mechanism
sl@0	1317	now provides almost all of the generic functions of Borenstein's and
sl@0	1318	Rose's Safe-Tcl (but not any Tk or email-related stuff). (JL)
sl@0	1319
sl@0	1320	9/11/95 (feature change) Changed file management so that files are
sl@0	1321	no longer shared between interpreters: a file cannot normally be
sl@0	1322	referenced in one interpreter if it was opened in another. This
sl@0	1323	feature is needed to support safe interpreters. Added Tcl_ShareHandle()
sl@0	1324	procedure for allowing files to be shared, and added "interp" argument
sl@0	1325	to Tcl_FilePermissions procedure. (JL)
sl@0	1326	* POTENTIAL INCOMPATIBILITY *
sl@0	1327
sl@0	1328	9/11/95 (new feature) Added "AssocData" mechanism, whereby extensions
sl@0	1329	can associate their own data with an interpreter and get called back
sl@0	1330	when the interpreter is deleted. This is visible at C level via the
sl@0	1331	procedures Tcl_SetAssocData and Tcl_GetAssocData. (JL)
sl@0	1332
sl@0	1333	9/11/95 (new feature) Added Tcl_ErrnoMsg to translate an errno value
sl@0	1334	into a human-readable string. This is now used instead of calling
sl@0	1335	strerror because strerror mesages vary dramatically from platform
sl@0	1336	to platform, which messes up Tcl tests. Tcl_ErrnoMsg uses the standard
sl@0	1337	POSIX messages for all the common signals, and calls strerror for
sl@0	1338	signals it doesn't understand.
sl@0	1339
sl@0	1340	----------------- Released patch 7.4p2, 9/15/95 -----------------------
sl@0	1341
sl@0	1342	----------------- Released 7.5a1, 9/15/95 -----------------------
sl@0	1343
sl@0	1344	9/22/95 (bug fix) Changed auto_mkindex to create tclIndex files that
sl@0	1345	handle directories whose paths might contain spaces. (RJ)
sl@0	1346
sl@0	1347	9/27/95 (bug fix) The "format" command didn't check for huge or negative
sl@0	1348	width specifiers, which could cause core dumps. (JO)
sl@0	1349
sl@0	1350	9/27/95 (bug fix) Core dumps could occur if an interactive command typed
sl@0	1351	to tclsh returned a very long result for tclsh to print out. The bug is
sl@0	1352	actually in printf (in Solaris 2.3 and 2.4, at least); switched to use
sl@0	1353	puts instead. (JO)
sl@0	1354
sl@0	1355	9/28/95 (bug fix) Changed makefile.bc to eliminate a false dependency
sl@0	1356	for tcl1675.dll on the Borland run time library. (SS)
sl@0	1357
sl@0	1358	9/28/95 (bug fix) Fixed tcl75.dll so it looks for tcl1675.dll instead
sl@0	1359	of tcl16.dll. (SS)
sl@0	1360
sl@0	1361	9/28/95 (bug fix) Tcl was not correctly detecting the difference
sl@0	1362	between Win32s and Windows '95. (SS)
sl@0	1363
sl@0	1364	9/28/95 (bug fix) "exec" was not passing environment changes to child
sl@0	1365	processes under Windows. (SS)
sl@0	1366
sl@0	1367	9/28/95 (bug fix) Changed Tcl to ensure that open files are not passed
sl@0	1368	to child processes under Windows. (SS)
sl@0	1369
sl@0	1370	9/28/95 (bug fix) Fixed Windows '95 and NT versions of exec so it can
sl@0	1371	handle both console and windows apps. (SS)
sl@0	1372
sl@0	1373	9/28/95 (bug fix) Fixed Windows version of exec so it no longer leaves
sl@0	1374	temp files lying around. Also changed it so the temp files are
sl@0	1375	created in the appropriate system dependent temp directory. (SS)
sl@0	1376
sl@0	1377	9/28/95 (bug fix) Eliminated source dependency on the Win32s Universal
sl@0	1378	Thunk header file, since it is not bundled with VC++. (SS)
sl@0	1379
sl@0	1380	9/28/95 (bug fix) Under Windows, Tcl now constructs the HOME
sl@0	1381	environment variable from HOMEPATH and HOMEDRIVE when HOME is not
sl@0	1382	already set. (SS)
sl@0	1383
sl@0	1384	9/28/95 (bug fix) Added support for "info nameofexecutable" and "info
sl@0	1385	sharedlibextension" to the Windows version. (SS)
sl@0	1386
sl@0	1387	9/28/95 (bug fix) Changed tclsh to correctly parse command line
sl@0	1388	arguments so that backslashes are preserved under Windows. (SS)
sl@0	1389
sl@0	1390	9/29/95 (bug fix) Tcl 7.5a1 treated either return or newline as end
sl@0	1391	of line in "gets", which caused lines ending in CRLF to be treated as
sl@0	1392	two separate lines. Changed to allow only character as end-of-line:
sl@0	1393	carriage return on Macs, newline elsewhere. (JO)
sl@0	1394
sl@0	1395	9/29/95 (new feature) Changed to install "configInfo" file in same
sl@0	1396	directory as library scripts. It didn't used to get installed. (JO)
sl@0	1397
sl@0	1398	9/29/95 (bug fix) Tcl was not converting Win32 errors into POSIX
sl@0	1399	errors under some circumstances. (SS)
sl@0	1400
sl@0	1401	10/2/95 (bug fix) Safe interpreters no longer get initialized with
sl@0	1402	a call to Tcl_Init(). (JL)
sl@0	1403
sl@0	1404	10/1/95 (new feature) Added "tcl_platform" global variable to provide
sl@0	1405	environment information such as the instruction set and operating
sl@0	1406	system. (JO)
sl@0	1407
sl@0	1408	10/1/95 (bug fix) "exec" command wasn't always generating the
sl@0	1409	"child process exited abnormally" message when it should have. (JO)
sl@0	1410
sl@0	1411	10/2/95 (bug fix) Changed "mkLinks.tcl" so that the scripts it generates
sl@0	1412	won't create links that overwrite original manual entries (there was
sl@0	1413	a problem where pack-old.n was overwriting pack.n). (JO)
sl@0	1414
sl@0	1415	10/2/95 (feature change) Changed to use -ldl for dynamic loading under
sl@0	1416	Linux if it is available, but fall back to -ldld if it isn't. (JO)
sl@0	1417
sl@0	1418	10/2/95 (bug fix) File sharing was causing refcounts to reach 0
sl@0	1419	prematurely for stdin, stdout and stderr, under some circumstances. (JL)
sl@0	1420
sl@0	1421	10/2/95 (platform support) Added support for Visual C++ compiler on
sl@0	1422	Windows, Windows '95 and Windows NT, code donated by Gordon Chaffee. (JL)
sl@0	1423
sl@0	1424	10/3/95 (bug fix) Tcl now frees any libraries that it loads before it
sl@0	1425	exits. (SS)
sl@0	1426
sl@0	1427	10/03/95 (bug fix) Fixed bug in Macintosh ls command where the -l
sl@0	1428	and -C options would fail in anything but the HOME directory. (RJ)
sl@0	1429
sl@0	1430	----------------- Released 7.5a2, 10/6/95 -----------------------
sl@0	1431
sl@0	1432	10/10/95 (bug fix) "file dirnam /." was returning ":" on UNIX instead
sl@0	1433	of "/". (JO)
sl@0	1434
sl@0	1435	10/13/95 (bug fix) Eliminated dependency on MKS toolkit for generating
sl@0	1436	the tcl.def file from Borland object files. (SS)
sl@0	1437
sl@0	1438	10/17/95 (new features) Moved the event loop from Tcl to Tk, made major
sl@0	1439	revisions along the way:
sl@0	1440	- New Tcl commands: after, update, vwait (replaces "tkwait variable").
sl@0	1441	- "tkerror" is now replaced with "bgerror".
sl@0	1442	- The following procedures are similar to their old Tk counterparts:
sl@0	1443	Tcl_DoOneEvent, Tcl_Sleep, Tcl_DoWhenIdle, Tcl_CancelIdleCall,
sl@0	1444	Tcl_CreateFileHandler, Tcl_DeleteFileHandler, Tcl_CreateTimerHandler,
sl@0	1445	Tcl_DeleteTimerHandler, Tcl_BackgroundError.
sl@0	1446	- Revised notifier, add new concept of "event source" with the following
sl@0	1447	procedures: Tcl_CreateEventSource, Tcl_DeleteEventSource,
sl@0	1448	Tcl_WatchFile, Tcl_SetMaxBlockTime, Tcl_FileReady, Tcl_QueueEvent,
sl@0	1449	Tcl_WaitForEvent. (JO)
sl@0	1450
sl@0	1451	10/31/95 (new features) Implemented cross platform file name support to make
sl@0	1452	it easier to write cross platform scripts. Tcl now understands 4 file naming
sl@0	1453	conventions: Windows (both DOS and UNC), Mac, Unix, and Network. The network
sl@0	1454	convention is a new naming mechanism that can be used to paths in a platform
sl@0	1455	independent fashion. See the "file" command manual page for more details.
sl@0	1456	The primary interfaces changes are:
sl@0	1457	- All Tcl commands that expect a file name now accept both network and
sl@0	1458	native form.
sl@0	1459	- Two new "file" subcommands, "nativename" and "networkname", provide a
sl@0	1460	way to convert between network and native form.
sl@0	1461	- Renamed Tcl_TildeSubst to Tcl_TranslateFileName, and changed it so that
sl@0	1462	it always returns a filename in native form. Tcl_TildeSubst is defined
sl@0	1463	as a macro for backward compatibility, but it is deprecated. (SS)
sl@0	1464
sl@0	1465	11/5/95 (new feature) Made "tkerror" and "bgerror" synonyms, so that
sl@0	1466	either name can be used to manipulate the command (provides temporary
sl@0	1467	backward compatibility for existing scripts that use tkerror). (JO)
sl@0	1468
sl@0	1469	11/5/95 (new feature) Added exit handlers and new C procedures
sl@0	1470	Tcl_CreateExitHandler, Tcl_DeleteExitHandler, and Tcl_Exit. (JO)
sl@0	1471
sl@0	1472	11/6/95 (new feature) Added pid command for Macintosh version of
sl@0	1473	Tcl (it didn't previously exist on the Mac). (RJ)
sl@0	1474
sl@0	1475	11/7/95 (new feature) New generic IO facility and support for IO to
sl@0	1476	files, pipes and sockets based on a common buffering scheme. Support
sl@0	1477	for asynchronous (non-blocking) IO and for event driver IO. Support
sl@0	1478	for automatic (background) asynchronous flushing and asynchronous
sl@0	1479	closing of channels. (JL)
sl@0	1480
sl@0	1481	11/7/95 (new feature) Added new commands "fconfigure" and "fblocked"
sl@0	1482	to support new I/O features such as nonblocking I/O. Added "socket"
sl@0	1483	command for creating TCP client and server sockets. (JL).
sl@0	1484
sl@0	1485	11/7/95 (new feature) Complete set of C APIs to the new generic IO
sl@0	1486	facility:
sl@0	1487	- Opening channels: Tcl_OpenFileChannel, Tcl_OpenCommandChannel,
sl@0	1488	Tcl_OpenTcpClient, Tcl_OpenTcpServer.
sl@0	1489	- I/O procedures on channels, which roughly mirror the ANSI C stdio
sl@0	1490	library: Tcl_Read, Tcl_Gets, Tcl_Write, Tcl_Flush, Tcl_Seek,
sl@0	1491	Tcl_Tell, Tcl_Close, Tcl_Eof, Tcl_InputBlocked, Tcl_GetChannelOption,
sl@0	1492	Tcl_SetChannelOption.
sl@0	1493	- Extension mechanism for creating new kinds of channels:
sl@0	1494	Tcl_CreateChannel, Tcl_GetChannelInstanceData, Tcl_GetChannelType,
sl@0	1495	Tcl_GetChannelName, Tcl_GetChannelFile, Tcl_RegisterChannel,
sl@0	1496	Tcl_UnregisterChannel, Tcl_GetChannel.
sl@0	1497	- Event-driven I/O on channels: Tcl_CreateChannelHandler,
sl@0	1498	Tcl_DeleteChannelHandler. (JL)
sl@0	1499
sl@0	1500	11/7/95 (new feature) Channel driver interface specification to allow
sl@0	1501	new types of channels to be added easily to Tcl. Currently being used
sl@0	1502	in three drivers - for files, pipes and TCP-based sockets. (JL).
sl@0	1503
sl@0	1504	11/7/95 (new feature) interp delete now takes any number of path
sl@0	1505	names of interpreters to delete, including zero. (JL).
sl@0	1506
sl@0	1507	11/8/95 (new feature) implemented 'info hostname' and Tcl_GetHostName
sl@0	1508	command to get host name of machine on which the Tcl process is running. (JL)
sl@0	1509
sl@0	1510	11/9/95 (new feature) Implemented file APIs for access to low level files
sl@0	1511	on each system. The APIs are: Tcl_CloseFile, Tcl_OpenFile, Tcl_ReadFile,
sl@0	1512	Tcl_WriteFile and Tcl_SeekFile. Also implemented Tcl_WaitPid which waits
sl@0	1513	in a system dependent manner for a child process. (JL)
sl@0	1514
sl@0	1515	11/9/95 (new feature) Added Tcl_UpdateLinkedVar procedure to force a
sl@0	1516	Tcl variable to be updated after its C variable changes. (JO)
sl@0	1517
sl@0	1518	11/9/95 (bug fix) The glob command has been totally reimplemented so
sl@0	1519	that it can support different file name conventions. It now handles
sl@0	1520	Windows file names (both UNC and drive-relative) properly. It also
sl@0	1521	supports nested braces correctly now. (SS)
sl@0	1522
sl@0	1523	11/13/95 (bug fix) Fixed Makefile.in so that configure can be run
sl@0	1524	from a clean directory separate from the Tcl source tree, and compilations
sl@0	1525	can be performed there. (JO)
sl@0	1526
sl@0	1527	11/14/95 (bug fix) Fixed file sharing between interpreters and file
sl@0	1528	transferring between interpreters to correctly manage the refcount so that
sl@0	1529	files are closed when the last reference to them is discarded. (JL)
sl@0	1530
sl@0	1531	11/14/95 (bug fix) Fixed gettimeofday implementation for the
sl@0	1532	Macintosh. This fixes several timing related bugs. (RJ)
sl@0	1533
sl@0	1534	11/17/95 (new feature) Added missing support for info nameofexecutable
sl@0	1535	on the Macintosh. (RJ)
sl@0	1536
sl@0	1537	11/17/95 (bug fix) The Tcl variables argc argv and argv0 now return
sl@0	1538	something reasonable on the Mac. (RJ)
sl@0	1539
sl@0	1540	11/22/95 (new feature) Implemented "auto-detect" mode for end of line
sl@0	1541	translations. On input, standalone "\r" mean MAC mode, standalone "\n"
sl@0	1542	mean Unix mode and "\r\n" means Windows mode. On output, the mode is
sl@0	1543	modified to whatever the platform specific mode for that platform is. (JL)
sl@0	1544
sl@0	1545	11/24/95 (feature change) Replaced "configInfo" file with tclConfig.sh,
sl@0	1546	which is more complete and uses slightly different names. Also
sl@0	1547	arranged for tclConfig.sh to be installed in the platform-specific
sl@0	1548	library directory instead of Tcl's script library directory. (JO)
sl@0	1549	* POTENTIAL INCOMPATIBILITY with Tcl 7.5a2, but not with Tcl 7.4 *
sl@0	1550
sl@0	1551	----------------- Released patch 7.4p3, 11/28/95 -----------------------
sl@0	1552
sl@0	1553	12/5/95 (new feature) Added Tcl_File facility to support platform-
sl@0	1554	independent file handles. Changed all interfaces that used Unix-
sl@0	1555	style integer fd's to use Tcl_File's instead. (SS)
sl@0	1556	* POTENTIAL INCOMPATIBILITY *
sl@0	1557
sl@0	1558	12/5/95 (new feature) Added a new "clock" command to Tcl. The command
sl@0	1559	allows you to get the current "clicks" or seconds & allows you to
sl@0	1560	format or scan human readable time/date strings. (RJ)
sl@0	1561
sl@0	1562	12/18/95 (new feature) Moved Tk_Preserve, Tk_Release, and Tk_EventuallyFree
sl@0	1563	to Tcl, renamed to Tcl_Preserve, Tcl_Release, and Tcl_EventuallyFree. (JO)
sl@0	1564
sl@0	1565	12/18/95 (new feature) Added new "package" command and associated
sl@0	1566	procedures Tcl_PkgRequire and Tcl_PkgProvide. Also wrote
sl@0	1567	pkg_mkIndex library procedure to create index files from binaries
sl@0	1568	and scripts. (JO)
sl@0	1569
sl@0	1570	12/20/95 (new feature) Added Tcl_WaitForFile procedure. (JO)
sl@0	1571
sl@0	1572	12/21/95 (new features) Made package name argument to "load" optional
sl@0	1573	(Tcl will now attempt to guess the package name if necessary). Also
sl@0	1574	added Tcl_StaticPackage and support in "load" for statically linked
sl@0	1575	packages. (JO)
sl@0	1576
sl@0	1577	12/22/95 (new feature) Upgraded the foreach command to accept multiple
sl@0	1578	loop variables and multiple value lists. This lets you iterate over
sl@0	1579	multiple lists in parallel, and/or assign multiple loop variables from
sl@0	1580	one value list during each iteration. The only potential compatibility
sl@0	1581	problem is with scripts that used loop variables with a name that could be
sl@0	1582	construed to be a list of variable names (i.e. contained spaces). (BW)
sl@0	1583
sl@0	1584	1/5/96 (new feature) Changed tclsh so it builds as a console mode
sl@0	1585	application under Windows. Now tclsh can be used from the command
sl@0	1586	line with pipes or interactively. Note that this only works under
sl@0	1587	Windows 95 or NT. (SS)
sl@0	1588
sl@0	1589	1/17/96 (new feature) Modified Makefile and configure script to allow
sl@0	1590	Tcl to be compiled as a shared library: use the --enable-shared option
sl@0	1591	when configuing. (JO)
sl@0	1592
sl@0	1593	1/17/96 (removed obsolete features) Removed the procedures Tcl_EnterFile
sl@0	1594	and Tcl_GetOpenFile: these no longer make sense with the new I/O system. (JL)
sl@0	1595	* POTENTIAL INCOMPATIBILITY *
sl@0	1596
sl@0	1597	1/19/96 (bug fixes) Prevented formation of circular aliases, through the
sl@0	1598	Tcl 'interp alias' command and through the 'rename' command, as well as
sl@0	1599	through the C API Tcl_CreateAlias. (JL)
sl@0	1600
sl@0	1601	1/19/96 (bug fixes) Fixed several bugs in direct deletion of interpreters
sl@0	1602	with Tcl_DeleteInterp when the interpreter is a slave; fixes based on a
sl@0	1603	patch received from Viktor Dukhovni of ESM. (JL)
sl@0	1604
sl@0	1605	1/19/96 (new feature) Implemented on-close handlers for channels; added
sl@0	1606	the C APIs Tcl_CreateCloseHandler and Tcl_DeleteCloseHandler. (JL)
sl@0	1607
sl@0	1608	1/19/96 (new feature) Implemented portable error reporting mechanism; added
sl@0	1609	the C APIs Tcl_SetErrno and Tcl_GetErrno. (JL)
sl@0	1610
sl@0	1611	1/24/96 (bug fix) Unknown command processing properly invokes external
sl@0	1612	commands under Windows NT and Windows '95 now. (SS)
sl@0	1613
sl@0	1614	1/23/96 (bug fix) Eliminated extremely long startup times under Windows '95.
sl@0	1615	The problem was a result of the option database initialization code that
sl@0	1616	concatenated $HOME with /.Xdefaults, resulting in a // in the middle of the
sl@0	1617	file name. Under Windows '95, this is incorrectly interpreted as a UNC
sl@0	1618	path. They delays came from the network timeouts needed to determine that
sl@0	1619	the file name was invalid. Tcl_TranslateFileName now suppresses duplicate
sl@0	1620	slashes that aren't at the beginning of the file name. (SS)
sl@0	1621
sl@0	1622	1/25/96 (bug fix) Changed exec and open to create children so they are
sl@0	1623	attached to the application's console if it exists. (SS)
sl@0	1624
sl@0	1625	1/31/96 (bug fix) Fixed command line parsing to handle embedded
sl@0	1626	spaces under Windows. (SS)
sl@0	1627
sl@0	1628	----------------- Released 7.5b1, 2/1/96 -----------------------
sl@0	1629
sl@0	1630	2/7/96 (bug fix) Fixed off by one error in argument parsing code under
sl@0	1631	Windows. (SS)
sl@0	1632
sl@0	1633	2/7/96 (bug fix) Fixed bugs in VC++ makefile that improperly
sl@0	1634	initialized the tcl75.dll. Fixed bugs in Borland makefile that caused
sl@0	1635	build failures under Windows NT. (SS)
sl@0	1636
sl@0	1637	2/9/96 (bug fix) Fixed deadlock problem in AUTO end of line translation
sl@0	1638	mode which would cause a socket server with several concurrent clients
sl@0	1639	writing in CRLF mode to hang. (JL)
sl@0	1640
sl@0	1641	2/9/96 (API change) Replaced -linemode option to fconfigure with a
sl@0	1642	new -buffering option, added "none" setting to enable immediate write. (JL)
sl@0	1643	* INCOMPATIBILITY with b1 *
sl@0	1644
sl@0	1645	2/9/96 (new feature) Added C API Tcl_InputBuffered which returns the count
sl@0	1646	of bytes currently buffered in the input buffer of a channel, and o for
sl@0	1647	output only channels. (JL)
sl@0	1648
sl@0	1649	2/9/96 (new feature) Implemented asynchronous connect for sockets. (JL)
sl@0	1650
sl@0	1651	2/9/96 (new feature) Added C API Tcl_SetDefaultTranslation to set (per
sl@0	1652	channel) the default end of line translation mode. This is the mode that
sl@0	1653	will be installed if an output operation is done on the channel while it is
sl@0	1654	still in AUTO mode. (JL)
sl@0	1655
sl@0	1656	2/9/96 (bug fix) Changed Tcl_OpenCommandChannel interface to properly
sl@0	1657	handle all of the combinations of stdio inheritance in background
sl@0	1658	pipelines. See the Tcl_OpenFileChannel(3) man page for more
sl@0	1659	info. This change fixes the bug where exec of a background pipeline
sl@0	1660	was not getting passed the stdio handles properly. (SS)
sl@0	1661
sl@0	1662	2/9/96 (bug fix) Removed the new Tcl_CreatePipeline interface, and
sl@0	1663	restored the old version for Unix platforms only. All new code should
sl@0	1664	use Tcl_CreateCommandChannel instead. (SS)
sl@0	1665
sl@0	1666	2/9/96 (bug fix) Changed Makefile.in to use -L and -ltcl7.5 for Tcl
sl@0	1667	library so that shared libraries are more likely to be found correctly
sl@0	1668	on more platforms. (JO)
sl@0	1669
sl@0	1670	2/13/96 (new feature) Added C API Tcl_SetNotifierData and
sl@0	1671	Tcl_GetNotifierData to allow notifier and channel driver writers to
sl@0	1672	associate data with a Tcl_File. The result of this change is that
sl@0	1673	Tcl_GetFileInfo now always returns an OS file handle, and Tcl_GetFile
sl@0	1674	can be used to construct a Tcl_File for an externally constructed OS
sl@0	1675	handle. (SS)
sl@0	1676
sl@0	1677	2/13/96 (bug fix) Changed Windows socket implementation so it doesn't
sl@0	1678	set SO_REUSEADDR on server sockets. Now attempts to create a server
sl@0	1679	socket on a port that is already in use will be properly identified
sl@0	1680	and an error will be generated. (SS)
sl@0	1681
sl@0	1682	2/13/96 (bug fix) Fixed problems with DLL initialization under Visual
sl@0	1683	C++ that left the C run time library uninitialized. (SS)
sl@0	1684
sl@0	1685	2/13/96 (bug fix) Fixed Windows socket initialization so it loads
sl@0	1686	winsock the first time it is used, rather than at the time tcl75.dll
sl@0	1687	is loaded. This should fix the bug where the modem immediately starts
sl@0	1688	trying to connect to a service provider when wish or tclsh are
sl@0	1689	started. (SS)
sl@0	1690
sl@0	1691	2/13/96 (new feature) Added C APIs Tcl_MakeFileChannel and
sl@0	1692	Tcl_MakeTcpClientChannel to wrap up existing fds and sockets into
sl@0	1693	channels. Provided implementations on Unix and Windows. (JL)
sl@0	1694
sl@0	1695	2/13/96 (bug fix) Fixed bug with seek leaving EOF and BLOCKING set. (JL)
sl@0	1696
sl@0	1697	2/14/96 (bug fix) Fixed reentrancy problem in fileevent handling
sl@0	1698	and made it more robust in the face of errors. (JL)
sl@0	1699
sl@0	1700	2/14/96 (feature change) Made generic IO level emulate blocking mode if the
sl@0	1701	channel driver is unable to provide it, e.g. if the low level device is
sl@0	1702	always nonblocking. Thus, now blocking behavior is an advisory setting for
sl@0	1703	channel drivers and can be ignored safely if the channel driver is unable
sl@0	1704	to provide it. (JL)
sl@0	1705
sl@0	1706	2/15/96 (new feature) Added "binary" end of line translation mode, which is
sl@0	1707	a synonym of "lf" mode. (JL)
sl@0	1708
sl@0	1709	2/15/96 (bug fix) Fixed reentrancy problem in fileevent handling vs
sl@0	1710	deletion of channel event handlers. (JL)
sl@0	1711
sl@0	1712	2/15/96 (bug fix) Fixed bug in event handling which would cause a
sl@0	1713	nonblocking channel to not see further readable events after the first
sl@0	1714	readable event that had insufficient input. (JL)
sl@0	1715
sl@0	1716	2/17/96 (bug fix) "info complete" didn't properly handle comments
sl@0	1717	in nested commands. (JO)
sl@0	1718
sl@0	1719	2/21/96 (bug fix) "exec" under Windows NT/95 did not properly handle
sl@0	1720	very long command lines (>200 chars). (SS)
sl@0	1721
sl@0	1722	2/21/96 (bug fix) Sockets could get into an infinite loop if a read
sl@0	1723	event arrived after all of the available data had been read. (SS)
sl@0	1724
sl@0	1725	2/22/96 (bug fix) Added cast of st_size elements to (long) before
sl@0	1726	sprintf-ing in "file size" command. This is needed to handle systems
sl@0	1727	like NetBSD with 64-bit file offsets. (JO)
sl@0	1728
sl@0	1729	----------------- Released 7.5b2, 2/23/96 -----------------------
sl@0	1730
sl@0	1731	2/23/96 (bug fix) TCL_VARARGS macro in tcl.h wasn't defined properly
sl@0	1732	when compiling with C++. (JO)
sl@0	1733
sl@0	1734	2/24/96 (bug fix) Removed dependencies on Makefile in the UNIX Makefile:
sl@0	1735	this caused problems on some platforms (like Linux?). (JO)
sl@0	1736
sl@0	1737	2/24/96 (bug fix) Fixed configuration bug that made Tcl not compile
sl@0	1738	correctly on Linux machines with neither -ldl or -ldld. (JO)
sl@0	1739
sl@0	1740	2/24/96 (new feature) Added a block of comments and definitions to
sl@0	1741	Makefile.in to make it easier to have Tcl's TclSetEnv etc. replace
sl@0	1742	the library procedures setenv etc, so that calls to setenv etc. in
sl@0	1743	the application automatically update the Tcl "env" variable. (JO)
sl@0	1744
sl@0	1745	2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
sl@0	1746	to C API Tcl_Close and simplified closing of command channels. (JL)
sl@0	1747	* INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *
sl@0	1748
sl@0	1749	2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
sl@0	1750	to C type definition Tcl_DriverCloseProc; modified all channel drivers to
sl@0	1751	implement close procedures that accept the additional argument. (JL)
sl@0	1752	* INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *
sl@0	1753
sl@0	1754	2/28/96 (bug fix) Fixed memory leak that could occur if an upvar
sl@0	1755	referred to an element of an array in the same stack frame as the
sl@0	1756	upvar. (JO)
sl@0	1757
sl@0	1758	2/29/96 (feature change) Modified both Tcl_DoOneEvent and Tcl_WaitForEvent
sl@0	1759	so that they return immediately in cases where they would otherwise
sl@0	1760	block forever (e.g. if there are no event handlers of any sort). (JO)
sl@0	1761
sl@0	1762	2/29/96 (new feature) Added C APIs Tcl_GetChannelBufferSize and
sl@0	1763	Tcl_SetChannelBufferSize to set and retrieve the size, in bytes, for
sl@0	1764	buffers allocated to store input or output in a channel. (JL)
sl@0	1765
sl@0	1766	2/29/96 (new feature) Added option -buffersize to Tcl fconfigure command
sl@0	1767	to allow Tcl scripts to query and set the size of channel buffers. (JL)
sl@0	1768
sl@0	1769	2/29/96 (feature removed) Removed channel driver function to specify
sl@0	1770	the buffer size to use when allocating a buffer. Removed the C typedef
sl@0	1771	for Tcl_DriverBufferSizeProc. Channels are now created with a default
sl@0	1772	buffer size of 4K. (JL)
sl@0	1773	* INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *
sl@0	1774
sl@0	1775	2/29/96 (feature change) The channel driver function for setting blocking
sl@0	1776	mode on the device may now be NULL. If the generic code detects that the
sl@0	1777	function is NULL, operations that set the blocking mode on the channel
sl@0	1778	simply succeed. (JL)
sl@0	1779
sl@0	1780	3/2/96 (bug fix) Fixed core dump that could occur if a syntax error
sl@0	1781	(such as missing close paren) occurred in an array reference with a
sl@0	1782	very long array name. (JO)
sl@0	1783
sl@0	1784	3/4/96 (bug fix) Removed code in the "auto_load" procedure that deletes
sl@0	1785	all existing auto-load information whenever the "auto_path" variable
sl@0	1786	is changed. Instead, new information adds to what was already there.
sl@0	1787	Otherwise, changing the "auto_path" variable causes all package-
sl@0	1788	related information to be lost. If you really want to get rid of
sl@0	1789	existing auto-load information, use auto_reset before setting auto_path. (JO)
sl@0	1790
sl@0	1791	3/5/96 (new feature) Added version suffix to shared library names so that
sl@0	1792	Tcl will compile under NetBSD and FreeBSD (I hope). (JO)
sl@0	1793
sl@0	1794	3/6/96 (bug fix) Cleaned up error messages in new I/O system to correspond
sl@0	1795	more closely to old I/O system. (JO)
sl@0	1796
sl@0	1797	3/6/96 (new feature) Added -myaddr and -myport options to the socket
sl@0	1798	command, removed -tcp and -- options. This lets clients and servers
sl@0	1799	choose a particular interface. Also changed the default server address
sl@0	1800	from the hostname to INADDR_ANY. The server accept callback now gets
sl@0	1801	passed the client's port as well as IP address. The C interfaces for
sl@0	1802	Tcl_OpenTcpClient and Tcl_OpenTcpServer have changed to support the
sl@0	1803	above changes. (BW)
sl@0	1804	* POTENTIAL INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *
sl@0	1805
sl@0	1806	3/6/96 (changed feature) The library function auto_mkindex will now
sl@0	1807	default to using the pattern "*.tcl" if no pattern is given. (RJ)
sl@0	1808
sl@0	1809	3/6/96 (bug fix) The socket channel code for the Macintosh has been
sl@0	1810	rewritten to use native MacTcp. (RJ)
sl@0	1811
sl@0	1812	3/7/96 (new feature) Added Tcl_SetStdChannel and Tcl_GetStdChannel
sl@0	1813	interfaces to allow applications to explicitly set and get the global
sl@0	1814	standard channels. (SS)
sl@0	1815
sl@0	1816	3/7/96 (bug fix) Tcl did close not the file descriptors associated
sl@0	1817	with "stdout", etc. when the corresponding channels were closed. (SS)
sl@0	1818
sl@0	1819	3/7/96 (bug fix) Reworked shared library and dynamic loading stuff to
sl@0	1820	try to get it working under AIX. Added new @SHLIB_LD_LIBS@ autoconf
sl@0	1821	symbol as part of this. AIX probably doesn't work yet, but it should
sl@0	1822	be a lot closer. (JO)
sl@0	1823
sl@0	1824	3/7/96 (feature change) Added Tcl_ChannelProc typedef and changed the
sl@0	1825	signature of Tcl_CreateChannelHandler and Tcl_DeleteChannelHandler to take
sl@0	1826	Tcl_ChannelProc arguments instead of Tcl_FileProc arguments. This change
sl@0	1827	should not affect any code outside Tcl because the signatures of
sl@0	1828	Tcl_ChannelProc and Tcl_FileProc are compatible. (JL)
sl@0	1829
sl@0	1830	3/7/96 (API change) Modified signature of Tcl_GetChannelOption to return
sl@0	1831	an int instead of char , and to take a Tcl_DString argument. Modified
sl@0	1832	the implementation so that the option name can be NULL, to mean that the
sl@0	1833	call should retrieve a list of alternating option names and values. (JL)
sl@0	1834	* INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *
sl@0	1835
sl@0	1836	3/7/96 (API change) Added Tcl_DriverSetOptionProc, Tcl_DriverGetOptionProc
sl@0	1837	typedefs, added two slots setOptionProc and getOptionProc to the channel
sl@0	1838	type structure. These may be NULL to indicate that the channel type does
sl@0	1839	not support any options. (JL)
sl@0	1840	* INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *
sl@0	1841
sl@0	1842	3/7/96 (feature change) stdin, stdout and stderr can now be put into
sl@0	1843	nonblocking mode. (JL)
sl@0	1844
sl@0	1845	3/8/96 (feature change) Eliminated dependence on the registry for
sl@0	1846	finding the Tcl library files. (SS)
sl@0	1847
sl@0	1848	----------------- Released 7.5b3, 3/8/96 -----------------------
sl@0	1849
sl@0	1850	3/12/96 (feature improvement) Modified startup script to look in several
sl@0	1851	different places for the Tcl library directory. This should allow Tcl
sl@0	1852	to find the libraries under all but the weirdest conditions, even without
sl@0	1853	the TCL_LIBRARY environment variable being set. (JO)
sl@0	1854
sl@0	1855	3/13/96 (bug fix) Eliminated use of the "linger" option from the Windows
sl@0	1856	socket implementation. (JL)
sl@0	1857
sl@0	1858	3/13/96 (new feature) Added -peername and -sockname options for fconfigure
sl@0	1859	for socket channels. Code contributed by John Haxby of HP. (JL)
sl@0	1860
sl@0	1861	3/13/96 (bug fix) Fixed panic and core dump that would occur if the accept
sl@0	1862	callback script on a server socket encountered an error. (JL)
sl@0	1863
sl@0	1864	3/13/96 (feature change) Added -async option to the Tcl socket command.
sl@0	1865	If the command is creating a client socket and the flag is present, the
sl@0	1866	client is connected asynchronously. If the option is absent (the default),
sl@0	1867	the client socket is connected synchronously, and the command returns only
sl@0	1868	when the connection has been completed or failed. This change was suggested
sl@0	1869	by Mark Diekhans. (JL)
sl@0	1870
sl@0	1871	3/13/96 (feature change) Modified the signature of Tcl_OpenTcpClient to
sl@0	1872	take an additional int argument, async. If nonzero, the client is connected
sl@0	1873	to the server asynchronously. If the value is zero, the connection is made
sl@0	1874	synchronously, and the call to Tcl_OpenTcpClient returns only when the
sl@0	1875	connection fails or succeeds. This change was suggested by Mark Diekhans. (JL)
sl@0	1876	* INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *
sl@0	1877
sl@0	1878	3/14/96 (bug fix) "tclsh bogus_file_name" didn't print an error message. (JO)
sl@0	1879
sl@0	1880	3/14/96 (bug fix) Added new procedures to tclCkalloc.c so that libraries
sl@0	1881	and applications can be compiled with TCL_MEM_DEBUG even if Tcl isn't
sl@0	1882	(however, the converse is still not true). Patches provided by Jan
sl@0	1883	Nijtmans. (JO)
sl@0	1884
sl@0	1885	3/15/96 (bug fix) Marked standard IO handles of a process as close-on-exec
sl@0	1886	to fix bug in Ultrix where exec was not sharing standard IO handles with
sl@0	1887	subprocesses. Fix suggested by Mark Diekhans. (JL)
sl@0	1888
sl@0	1889	3/15/96 (bug fix) Fixed asynchronous close mechanism so that it closes the
sl@0	1890	channel instead of leaking system resources. The manifestation was that Tcl
sl@0	1891	would eventually run out of file descriptors if it was handling a large
sl@0	1892	number of nonblocking sockets or pipes with high congestion. (JL)
sl@0	1893
sl@0	1894	3/15/96 (bug fix) Fixed tests so that they no longer leak file descriptors.
sl@0	1895	The manifestation was that Tcl would eventually run out of file descriptors
sl@0	1896	if the tests were rerun many times (> a hundred times on Solaris). (JL)
sl@0	1897
sl@0	1898	3/15/96 (bug fix) Fixed channel creation code so that it never creates
sl@0	1899	unnamed channels. This would cause a panic and core dump when the channel
sl@0	1900	was closed. (JL)
sl@0	1901
sl@0	1902	3/16/96 (bug fixes) Made lots of changes in configuration stuff to get
sl@0	1903	Tcl working under AIX (finally). Tcl should now support the "load"
sl@0	1904	command under AIX and should work either with or without shared
sl@0	1905	libraries for Tcl and Tk. (JO)
sl@0	1906
sl@0	1907	3/21/96 (configuration improvement) Changed configure script so it
sl@0	1908	doesn't use version numbers (as in -ltcl7.5 and libtcl7.5.so) under
sl@0	1909	SunOS 4.1, where they don't work anyway. (JO)
sl@0	1910
sl@0	1911	3/22/96 (new feature) Added C API Tcl_InterpDeleted that allows extension
sl@0	1912	writers to discover when an interpreter is being deleted. (JL)
sl@0	1913
sl@0	1914	3/22/96 (bug fix) The standard IO channels are now added to each
sl@0	1915	trusted interpreter as soon as the interpreter is created. This ensures
sl@0	1916	against the bug where a child would do IO before the master had done any,
sl@0	1917	and then the child is destroyed - the standard IO channels would be then
sl@0	1918	closed and the master would be unable to do any IO. (JL)
sl@0	1919
sl@0	1920	3/22/96 (bug fix) Made Tcl more robust against interpreter deletion, by
sl@0	1921	using Tcl_Preserve, Tcl_Release and Tcl_EventuallyFree to split the process
sl@0	1922	of interpreter deletion into two distinct phases. Also went through all of
sl@0	1923	Tcl and added calls to Tcl_Preserve and Tcl_Delete where needed. (JL)
sl@0	1924
sl@0	1925	3/22/96 (bug fix) Fixed several places where C code was reading and writing
sl@0	1926	into freed memory, especially during interpreter deletion. (JL)
sl@0	1927
sl@0	1928	3/22/96 (bug fix) Fixed very deep bug in Tcl_Release that caused memory to
sl@0	1929	be freed twice if the release callback did Tcl_Preserve and Tcl_Release on
sl@0	1930	the same memory as the chunk currently being freed. (JL)
sl@0	1931
sl@0	1932	3/22/96 (bug fix) Removed several memory leaks that would cause memory
sl@0	1933	buildup on half-K chunks in the generic IO level. (JL)
sl@0	1934
sl@0	1935	3/22/96 (bug fix) Fixed several core dumps which occurred when new
sl@0	1936	AssocData was being created during the cleanups in interpreter deletion.
sl@0	1937	The solution implemented now is to loop repeatedly over the AssocData until
sl@0	1938	none is left to clean up. (JL)
sl@0	1939
sl@0	1940	3/22/96 (bug fix) Fixed a bug in event handling which caused an infinite
sl@0	1941	loop if there were no files being watched and no timer. Fix suggested by
sl@0	1942	Jan Nijtmans. (JL)
sl@0	1943
sl@0	1944	3/22/96 (bug fix) Fixed Tcl_CreateCommand, Tcl_DeleteCommand to be more
sl@0	1945	robust if the interpreter is being deleted. Also fixed several order
sl@0	1946	dependency bugs in Tcl_DeleteCommand which kicked in when an interpreter
sl@0	1947	was being deleted. (JL)
sl@0	1948
sl@0	1949	3/26/96 (bug fix) Upon a "short read", the generic code no longer calls
sl@0	1950	the driver for more input. Doing this caused blocking on some platforms
sl@0	1951	even on nonblocking channels. Bug and fix courtesy Mark Roseman. (JL)
sl@0	1952
sl@0	1953	3/26/96 (new feature) Added 'package Tcltest' which is present only in
sl@0	1954	test versions of Tcl; this allows the testing commands to be loaded into
sl@0	1955	new interpreters besides the main one. (JL)
sl@0	1956
sl@0	1957	3/26/96 (restored feature) Recreated the Tcl_GetOpenFile C API. You can
sl@0	1958	now get a FILE * from a registered channel; Unix only. (JL)
sl@0	1959
sl@0	1960	3/27/96 (bug fix) The regular expression code did not support more
sl@0	1961	than 9 subexpressions. It now supports up to 20. (SS)
sl@0	1962
sl@0	1963	4/1/96 (bug fixes) The CHANNEL_BLOCKED bit was being left on on a short
sl@0	1964	read, so that fileevents wouldn't fire correctly. Bug reported by Mark
sl@0	1965	Roseman.(JL, RJ)
sl@0	1966
sl@0	1967	4/1/96 (bug fix) Moved Tcl_Release to match Tcl_Preserve exactly, in
sl@0	1968	tclInterp.c; previously interpreters were being freed only conditionally
sl@0	1969	and sometimes not at all. (JL)
sl@0	1970
sl@0	1971	4/1/96 (bug fix) Fixed error reporting in slave interpreters when the
sl@0	1972	error message was being generated directly by C code. Fix suggested by
sl@0	1973	Viktor Dukhovni of ESM. (JL)
sl@0	1974
sl@0	1975	4/2/96 (bug fixes) Fixed a series of bugs in Windows sockets that caused
sl@0	1976	events to variously get lost, to get sent multiple times, or to be ignored
sl@0	1977	by the driver. The manifestation was blocking if the channel is blocking,
sl@0	1978	and either getting EAGAIN or infinite loops if the channel is nonblocking.
sl@0	1979	This series of bugs was found by Ian Wallis of Cisco. Now all tests (also
sl@0	1980	those that were previously commented out) in socket.test pass. (JL, SS)
sl@0	1981
sl@0	1982	4/2/96 (feature change/bug fix) Eliminated network name support in
sl@0	1983	favor of better native name support. Added "file split", "file join",
sl@0	1984	and "file pathtype" commands. See the "file" man page for more
sl@0	1985	details. (SS)
sl@0	1986	* INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *
sl@0	1987
sl@0	1988	4/2/96 (bug fix) Changed implementation of auto_mkindex so tclIndex
sl@0	1989	files will properly handle path names in a cross platform context. (SS)
sl@0	1990
sl@0	1991	4/5/96 (bug fix) Fixed Tcl_ReadCmd to use the channel buffer size as the
sl@0	1992	chunk size it reads, instead of a fixed 4K size. Thus, on large reads, the
sl@0	1993	user can set the channel buffer size to a large size and the read will
sl@0	1994	occur orders of magnitude faster. For example, on a 2MB file, reading in 4K
sl@0	1995	chunks took 34 seconds, while reading in 1MB chunks took 1.5 seconds (on a
sl@0	1996	SS-20). Problem identified and fix suggested by John Haxby of HP. (JL)
sl@0	1997
sl@0	1998	4/5/96 (bug fix) Fixed socket creation code to invoke gethostbyname only if
sl@0	1999	inet_addr failed (very unlikely). Before this change the order was reversed
sl@0	2000	and this made things much slower than they needed to be (gethostbyname
sl@0	2001	generally requires an RPC, which is slow). Problem identified and fix
sl@0	2002	suggested by John Loverso of OSF. (JL)
sl@0	2003
sl@0	2004	4/9/96 (feature change) Modified "auto" translation mode so that it
sl@0	2005	recognizes any of "\n", "\r" and "\r\n" in input as end of line, so
sl@0	2006	that a file can have mixed end-of-line sequences. It now outputs
sl@0	2007	the platform specific end of line sequence on each platform for files and
sl@0	2008	pipes, and for sockets it produces crlf in output on all platforms. (JL)
sl@0	2009	* INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *
sl@0	2010
sl@0	2011	4/11/96 (new feature) Added -eofchar option to Tcl_SetChannelOption to allow
sl@0	2012	setting of an end of file character for input and output. If an input eof
sl@0	2013	char is set, it is recognized as EOF and further input from the channel is
sl@0	2014	not presented to the caller. If an output eof char is set, on output, that
sl@0	2015	byte is appended to the channel when it is closed. On Unix and Macintosh,
sl@0	2016	all channels start with no eof char set for input or output. On Windows,
sl@0	2017	files and pipes start with input and output eof chars set to Crlt-Z (ascii
sl@0	2018	26), and sockets start with no input or output eof char. (JL)
sl@0	2019	* INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *
sl@0	2020
sl@0	2021	4/17/96 (bug fix) Fixed series of bugs with handling of crlf sequence split
sl@0	2022	across buffer boundaries in input, in AUTO mode. (JL, BW)
sl@0	2023
sl@0	2024	4/17/96 (test suite improvement) Fixed test suite so that tests that
sl@0	2025	depend on the availability of Unix commands such as echo, cat and others
sl@0	2026	are not run if these commands are not present. (JL)
sl@0	2027
sl@0	2028	4/17/96 (test suite improvement) The socket test now automatically starts,
sl@0	2029	on platformst that support exec, a separate process for remote testsing. (JL)
sl@0	2030
sl@0	2031	----------------- Released 7.5, 4/21/96 -----------------------
sl@0	2032
sl@0	2033	5/1/96 (bug fix) "file tail ~" did not correctly return the tail
sl@0	2034	portion of the user's home directory. (SS)
sl@0	2035
sl@0	2036	5/1/96 (bug fix) Fixed bug in TclGetEnv where it didn't lookup environment
sl@0	2037	variables correctly: could confuse "H" and "HOME", for example. (JO)
sl@0	2038
sl@0	2039	5/1/96 (bug fix) Changed to install tclConfig.sh under "make install-binaries",
sl@0	2040	not "make install-libraries". (JO)
sl@0	2041
sl@0	2042	5/2/96 (bug fix) Changed pkg_mkIndex not to attempt to "load" a file unless
sl@0	2043	it has the standard shared library extension. On SunOS, attempts to load
sl@0	2044	Tcl scripts cause the whole application to be aborted (there's no way to
sl@0	2045	get the error back into Tcl). (JO)
sl@0	2046
sl@0	2047	5/7/96 (bug fix) Moved initScript in tclUnixInit.c to writable memory to
sl@0	2048	avoid potential core dumps. (JO)
sl@0	2049
sl@0	2050	5/7/96 (bug fix) Auto_reset procedure was removing procedure from init.tcl,
sl@0	2051	such as pkg_mkIndex. (JO)
sl@0	2052
sl@0	2053	5/7/96 (bug fix) Fixed cast on socket address resolution code that
sl@0	2054	would cause a failure to connect on Dec Alphas. (JL)
sl@0	2055
sl@0	2056	5/7/96 (bug fix) Added "time", "subst" and "fileevent" commands to set of
sl@0	2057	commands available in a safe interpreter. (JL)
sl@0	2058
sl@0	2059	5/13/96 (bug fix) Preventing OS level handles for stdin, stdout and stderr
sl@0	2060	from being implicitly closed when the last reference to the standard
sl@0	2061	channel containing that handle is discarded when an interpreter is deleted.
sl@0	2062	Explicitly closing standard channels by using "close" still works. (JL)
sl@0	2063
sl@0	2064	5/21/96 (bug fix) Do not create channels for stdin, stdout and stderr on
sl@0	2065	Unix if the devices are closed. This prevents a duplicate channel name
sl@0	2066	panic later on when the fd is used to open a channel and the channel is
sl@0	2067	registered in an interpreter. (JL)
sl@0	2068
sl@0	2069	5/23/96 (bug fix) Fixed bug that prevented the use of standard channels in
sl@0	2070	interpreters created after the last interpreter was destroyed. In the sequence
sl@0	2071
sl@0	2072	interp = Tcl_CreateInterp();
sl@0	2073	Tcl_DeleteInterp(interp);
sl@0	2074	interp = Tcl_CreateInterp();
sl@0	2075
sl@0	2076	channels for stdio would not be available in the second interpreter. (JL)
sl@0	2077
sl@0	2078	5/23/96 (bug fix) Fixed bug that allowed Tcl_MakeFileChannel to create new
sl@0	2079	channels with Tcl_Files in them that are already used by another channel.
sl@0	2080	This would cause core dumps when the Tcl_Files were being freed twice. (JL)
sl@0	2081
sl@0	2082	5/23/96 (bug fix) Fixed a logical timing bug that caused a standard channel
sl@0	2083	to be removed from the standard channel table too early when the channel
sl@0	2084	was being closed. If the channel was being flushed asynchronously, it could
sl@0	2085	get recreated before being actually destroyed, and the recreated channel
sl@0	2086	would contain the same Tcl_File as the one being closed, leading to
sl@0	2087	dangling pointers and core dumps. (JL)
sl@0	2088
sl@0	2089	5/27/96 (bug fix) Fixed a bug in Tcl_GetChannelOption which caused it to
sl@0	2090	always return a list of one element, a list of the settings, for
sl@0	2091	-translation and -eofchar options. Now correctly returns the value
sl@0	2092	described by the documentation (Mark Diekhans found this, thanks!). (JL)
sl@0	2093
sl@0	2094	5/30/96 (bug fix) Fixed a couple of syntax errors in io.test. (JL)
sl@0	2095
sl@0	2096	5/30/96 (bug fix) If a fileevent scripts gets an error, delete it before
sl@0	2097	causing a background error. This is to allow the error handler to reinstall
sl@0	2098	the fileevent and to prevent infinite loops if the event loop is reentered
sl@0	2099	in the error handler. (JL)
sl@0	2100
sl@0	2101	5/31/96 (bug fix) Channels now will get properly flushed on exit. (JL)
sl@0	2102
sl@0	2103	6/5/96 (bug fix) Changed Tcl_Ckalloc, Tcl_Ckfree, and Tcl_Ckrealloc to
sl@0	2104	Tcl_Alloc, Tcl_Free, and Tcl_Realloc. Added documentation for these
sl@0	2105	routines now that they are officially supported. Extension writers
sl@0	2106	should use these routines instead of free() and malloc(). (SS)
sl@0	2107
sl@0	2108	6/10/96 (bug fix) Changes the Tcl close command so that it no longer
sl@0	2109	waits on nonblocking pipes for the piped processes to exit; instead it
sl@0	2110	reaps them in the background. (JL)
sl@0	2111
sl@0	2112	6/11/96 (bug fix) Increased the length of the listen queue for server
sl@0	2113	sockets on Unix from 5 to 100. Some OSes will disregard this and reset it
sl@0	2114	to 5, but we should try to get as long a queue as we can, for performance
sl@0	2115	reasons. (JL)
sl@0	2116
sl@0	2117	6/11/96 (bug fix) Fixed windows sockets bug that caused a cascade of events
sl@0	2118	if the fileevent script read less than was available. Now reading less than
sl@0	2119	is available does not cause a flood of Tcl events. (JL, SS)
sl@0	2120
sl@0	2121	6/11/96 (bug fix) Fixed bug in background flushing on closed channels that
sl@0	2122	would prevent the last buffer from getting flushed. (JL)
sl@0	2123
sl@0	2124	6/13/96 (bug fix) Fixed bug in Windows sockets that caused a core dump if
sl@0	2125	a DLL linked with tcl.dll and referred to e.g. ntohs() without opening a
sl@0	2126	Tcl socket. The problem was that the indirection table was not being
sl@0	2127	initialized. (JL)
sl@0	2128
sl@0	2129	6/13/96 (bug fix) Fixed OS level resource leak that would occur when a
sl@0	2130	Tcl channel was still registered in some interpreter when the process
sl@0	2131	exits. Previously the channel was not being closed and the OS level handles
sl@0	2132	were not being released; the output was being flushed but the device was
sl@0	2133	not being closed. Now the device is properly closed. This was only a
sl@0	2134	problem on Win3.1 and MacOS. (JL, SS)
sl@0	2135
sl@0	2136	6/28/96 (bug fix) Fixed bug where transient errors were leaving an error
sl@0	2137	code around, so that it would erroneously get reported later. This bug was
sl@0	2138	exercised intermittently by closing a channel to a file on a very loaded
sl@0	2139	NFS server, or to a socket whose other end blocked. (JL, BW)
sl@0	2140
sl@0	2141	7/3/96 (bug fix) Fileevents declared in an interpreter are now deleted
sl@0	2142	when the channel is closed in that interpreter. Before this fix, the
sl@0	2143	fileevent would hang around until the channel is completely closed, and
sl@0	2144	would cause errors if events happened before the channel was closed. This
sl@0	2145	could happen in two cases: first if the channel is shared between several
sl@0	2146	interpreters, and second if an async flush is in progress that prevents the
sl@0	2147	channel from being closed until the flush finishes. (JL)
sl@0	2148
sl@0	2149	7/10/96 (bug fix) Fixed bugs in both "lrange" and "lreplace" commands
sl@0	2150	where too much white space was being removed. For example, the command
sl@0	2151	lreplace {\}\ hello} end end
sl@0	2152	was returning "\}\", losing the significant space in the first list
sl@0	2153	element and corrupting the list. (JO)
sl@0	2154
sl@0	2155	7/20/96 (bug fix) The procedure pkg_mkIndex didn't work properly for
sl@0	2156	extensions that depend on Tk, because it didn't load Tk into the child
sl@0	2157	interpreter before loading the extension. Now it loads Tk if Tk is
sl@0	2158	present in the parent. (JO)
sl@0	2159
sl@0	2160	7/23/96 (bug fix) Added compat version of strftime to fix crashes
sl@0	2161	resulting from bad implementations under Windows. (SS)
sl@0	2162
sl@0	2163	7/23/96 (bug fix) Standard implementations of gmtime() and localtime()
sl@0	2164	under Windows did not handle dates before 1970, so they were replaced
sl@0	2165	with a revised implementation. (SS)
sl@0	2166
sl@0	2167	7/23/96 (bug fix) Tcl would crash on exit under Borland 5.0 because
sl@0	2168	the global environ pointer was left pointing to freed memory. (SS)
sl@0	2169
sl@0	2170	7/29/96 (bug fix) Fixed memory leak in Tcl_LoadCmd that could occur if
sl@0	2171	a package's AppInit procedure called Tcl_StaticPackage to register
sl@0	2172	static packages. (JO)
sl@0	2173
sl@0	2174	8/1/96 (bug fix) Fixed a series of bugs in Windows sockets so that async
sl@0	2175	writebehind in the presence of read event handlers now works, and so that
sl@0	2176	async writebehind also works on sockets for which a read event handler was
sl@0	2177	declared and whose channels were then closed before the async write
sl@0	2178	finished. The bug was reported by John Loverso and Steven Wahl,
sl@0	2179	independently, test case supplied by John Loverso. (JL)
sl@0	2180
sl@0	2181	----------------- Released patch 7.5p1, 8/2/96 -----------------------
sl@0	2182
sl@0	2183	5/8/96 (new feature) Added Tcl_GetChannelMode C API for retrieving whether
sl@0	2184	a channel is open for reading and writing. (JL)
sl@0	2185
sl@0	2186	5/8/96 (API changes) Revised C APIs for channel drivers:
sl@0	2187	- Removed all Tcl_Files from channel driver interface; you can now have
sl@0	2188	channels that are not based on Tcl_Files.
sl@0	2189	- Added channelReadyProc and watchChannelProc procedures to interface;
sl@0	2190	these are used to implement event notification for channels.
sl@0	2191	- Added getFileProc to channel driver, to allow the generic IO code
sl@0	2192	to retrieve a Tcl_File from a channel (presumably if the channel
sl@0	2193	uses Tcl_Files they will be stored inside its instanceData). (JL)
sl@0	2194	* INCOMPATIBILITY with Tcl 7.5 *
sl@0	2195
sl@0	2196	5/8/96 (API change) The Tcl_CreateChannel C API was modified to not take
sl@0	2197	Tcl_File arguments, and instead to take a mask specifying whether the
sl@0	2198	channel is readable and/or writable. (JL)
sl@0	2199	* INCOMPATIBILITY with Tcl 7.5 *
sl@0	2200
sl@0	2201	6/3/96 (bug fix) Made Tcl_SetVar2 robust against the case where the value
sl@0	2202	of the variable is a NULL pointer instead of "". (JL)
sl@0	2203
sl@0	2204	6/17/96 (bug fix) Fixed "reading uninitialized memory" error reported by
sl@0	2205	Purify, in Tcl_Preserve/Tcl_Release. (JL)
sl@0	2206
sl@0	2207	8/9/96 (bug fix) Fixed bug in init.tcl that caused incorrect error message
sl@0	2208	if the act of autoloading a procedure caused the procedure to be invoked
sl@0	2209	again. (JO)
sl@0	2210
sl@0	2211	8/9/96 (bug fix) Configure script produced bad library names and extensions
sl@0	2212	under SunOS and a few other platforms if the --disable-load switch was used.
sl@0	2213	(JO)
sl@0	2214
sl@0	2215	8/9/96 (bug fix) Tcl_UpdateLinkedVar generated an error if the variable
sl@0	2216	being updated was read-only. (JO)
sl@0	2217
sl@0	2218	8/14/96 (bug fix) The macintosh now supports synchronous socket
sl@0	2219	connections. Other minor bugs were also fixed. (RJ)
sl@0	2220
sl@0	2221	8/15/96 (configuration improvement) Changed the file patchlevel.h
sl@0	2222	to be tclPatch.h. This avoids conflict with the Tk file and is now
sl@0	2223	in 8.3 format on the Windows platform. (RJ)
sl@0	2224
sl@0	2225	8/20/96 (bug fix) Fixed core dump in interp alias command for interpreters
sl@0	2226	created with Tcl_CreateInterp (as opposed to with Tcl_CreateSlave). (JL)
sl@0	2227
sl@0	2228	8/20/96 (bug fix) No longer masking ECONNRESET on Windows sockets so
sl@0	2229	that the higher level of the IO mechanism sees the error instead of
sl@0	2230	entering an infinite loop. (JL)
sl@0	2231
sl@0	2232	8/20/96 (bug fix) Destroying the last interpreter no longer closes the
sl@0	2233	standard channels. (JL)
sl@0	2234
sl@0	2235	8/20/96 (bug fix) Closing one of the stdin, stdout or stderr channels and
sl@0	2236	then opening a new channel now correctly assigns the new channel as the
sl@0	2237	standard channel that was closed. (JL)
sl@0	2238
sl@0	2239	8/20/96 (bug fix) Added code to unix/tclUnixChan.c for using ioctl with
sl@0	2240	FIONBIO instead of fcntl with O_NONBLOCK, for those versions of Unix where
sl@0	2241	either O_NONBLOCK is not supported or implemented incorrectly. (JL)
sl@0	2242
sl@0	2243	8/21/96 (bug fix) Fixed "file extension" so it correctly returns the
sl@0	2244	extension on files like "foo..c" as "..c" instead of ".c". (SS)
sl@0	2245
sl@0	2246	8/22/96 (bug fix) If environ[] contains static strings, Tcl would core
sl@0	2247	dump in TclSetupEnv because it was trying to write NULLs into the actual
sl@0	2248	data in environ[]. Now we instead copy as appropriate. (JL)
sl@0	2249
sl@0	2250	8/22/96 (added impl) Added missing implementation of Tcl_MakeTcpClientChannel
sl@0	2251	for Windows platform. Code contributed by Mark Diekhans. (JL)
sl@0	2252
sl@0	2253	8/22/96 (new feature) Added a new memory allocator for the Macintosh
sl@0	2254	version of Tcl. It's quite a bit faster than MetroWerk's version. (RJ)
sl@0	2255
sl@0	2256	8/26/96 (documentation update) Removed old change bars (for all changes
sl@0	2257	in Tcl 7.5 and earlier releases) from manual entries. (JO)
sl@0	2258
sl@0	2259	8/27/96 (enhancement) The exec and open commands behave better and work in
sl@0	2260	more situations under Windows NT and Windows 95. Documentation describes
sl@0	2261	what is still lacking. (CS)
sl@0	2262
sl@0	2263	8/27/96 (enhancement) The Windows makefiles will now compile even if the
sl@0	2264	compiler is not in the path and/or the compiler's environment variables
sl@0	2265	have not been set up. (CS)
sl@0	2266
sl@0	2267	8/27/96 (configuration improvement) The Windows resource files are
sl@0	2268	automatically updated when the version/patch level changes. The header file
sl@0	2269	now has a comment that reminds the user which other files must be manually
sl@0	2270	updated when the version/patch level changes. (CS)
sl@0	2271
sl@0	2272	8/28/96 (new feature) Added file manipulation features (copy, rename, delete,
sl@0	2273	mkdir) that are supported on all platforms. They are implemented as
sl@0	2274	subcommands to the "file" command. See the documentation for the "file"
sl@0	2275	command for more information. (JH)
sl@0	2276
sl@0	2277	----------------- Released 7.6b1, 8/30/96 -----------------------
sl@0	2278
sl@0	2279	9/3/96 (bug fix) Simplified code so that standard channels are created
sl@0	2280	lazily, they are added to an interpreter lazily, and they are never added
sl@0	2281	to a safe interpreter. (JL)
sl@0	2282
sl@0	2283	9/3/96 (bug fix) Closing a channel after closing a standard channel, e.g.
sl@0	2284	stdout, would cause the implicit recreation of that standard channel. (JL)
sl@0	2285
sl@0	2286	9/3/96 (new feature) Now calling Tcl_RegisterChannel with a NULL
sl@0	2287	interpreter increments the refcount so that code outside any interpreter
sl@0	2288	can use channels that are also registered in interpreters, without worrying
sl@0	2289	that the channel may turn into a dangling pointer at any time. Calling
sl@0	2290	Tcl_UnregisterChannel with a NULL interpreter only decrements the recount
sl@0	2291	so that code outside any interpreter can safely declare it is no longer
sl@0	2292	interested in a channel. (JL)
sl@0	2293
sl@0	2294	9/4/96 (new features) Two changes to dynamic loading:
sl@0	2295	- If the file name is empty in the "load" command and there is no
sl@0	2296	statically loaded version of the package, a dynamically loaded
sl@0	2297	version will be used if there is one.
sl@0	2298	- Tcl_StaticPackage ignores redundant calls for the same package. (JO)
sl@0	2299
sl@0	2300	9/6/96 (bug fix) Platform specific procedures for manipulating files are
sl@0	2301	no longer macros and have been prefixed with "Tclp", such as TclpRenameFile.
sl@0	2302	Unix file code now handles symbolic links and other special files correctly.
sl@0	2303	The semantics of file copy and file rename has been changed so that if
sl@0	2304	a target directory exists, the source files will NOT be merged with the
sl@0	2305	existing files. (JH)
sl@0	2306
sl@0	2307	9/6/96 (bug fix) If standard channel is NULL, because Tcl cannot connect
sl@0	2308	to the standard channel, do not increment the refcount. The channel can
sl@0	2309	be NULL if there is for example no standard input. (JL)
sl@0	2310
sl@0	2311	9/6/96 (portability improvement) Changed parsing of backslash sequences
sl@0	2312	like \n to translate directly to absolute values like 0xa instead of
sl@0	2313	letting the compiler do the translation. This guarantees that the
sl@0	2314	translation is done the same everywhere. (JO)
sl@0	2315
sl@0	2316	9/9/96 (bug fix) If channel is opened and not associated with any
sl@0	2317	interpreter, but Tcl decides to use it as one of the standard channels, it
sl@0	2318	became impossible to close the channel with Tcl_Close -- instead you had
sl@0	2319	to call Tcl_UnregisterChannel. Fixed now so that it's safe to call
sl@0	2320	Tcl_Close even when Tcl is using the channel as one of the standard ones. (JL)
sl@0	2321
sl@0	2322	9/11/96 (feature change) The Tcl library is now placed in the Tcl
sl@0	2323	shared libraries resource. You no longer need to place the Tcl files
sl@0	2324	in your applications explicitly. (RJ)
sl@0	2325
sl@0	2326	9/11/96 (feature change) Extensions no longer automatically have the
sl@0	2327	resource fork of the extension opened for it. Instead you need to
sl@0	2328	use the tclMacLibrary.c file in your extension. (RJ)
sl@0	2329	* POTENTIAL INCOMPATIBILITY *
sl@0	2330
sl@0	2331	9/12/96 (bug fix) The extension loading mechanism on the Macintosh now
sl@0	2332	looks at the 'cfrg' resource to determine where to load the code
sl@0	2333	fragment from. This means FAT fragments should now work. (RJ)
sl@0	2334
sl@0	2335	9/18/96 (enhancement) The exec and open commands behave better and work in
sl@0	2336	more situations under Windows 3.X. Documentation describes what is still
sl@0	2337	lacking. (CS)
sl@0	2338
sl@0	2339	9/19/96 (bug fix) Fixed a panic which would occur if you delete a
sl@0	2340	non-existent alias before any aliases are created. Now instead correctly
sl@0	2341	returns an error that the alias is not found. (JL)
sl@0	2342
sl@0	2343	9/19/96 (bug fix) Slave interpreters could rename aliases and they would
sl@0	2344	not get deleted when the alias was being redefined. This led to dangling
sl@0	2345	pointers etc. (JL)
sl@0	2346
sl@0	2347	9/19/96 (bug fix) Fixed a panic where a hash table entry was being deleted
sl@0	2348	twice during alias management operations. (JL)
sl@0	2349
sl@0	2350	9/19/96 (bug fix) Fixed bug in event loop that could cause the input focus
sl@0	2351	in Tk to get confused during menu traversal, among other problems. The
sl@0	2352	problem was related to handling of the "marker" when its event was
sl@0	2353	deleted. (JO)
sl@0	2354
sl@0	2355	9/26/96 (bug fix) Windows was losing EOF on a socket if the FD_CLOSE event
sl@0	2356	happened to precede any left over FD_READ events. Now correctly remembers
sl@0	2357	seeing FD_CLOSE, so that trailing FD_READ events are not discarded if they
sl@0	2358	do not contain any data. This allows Tcl to correctly get a zero read and
sl@0	2359	notice EOF. (JL)
sl@0	2360
sl@0	2361	9/26/96 (bug fix) Was not resetting READABLE state properly on sockets
sl@0	2362	under Windows if the driver discarded an FD_READ event because no data was
sl@0	2363	present. Now correctly resets the state. (JL)
sl@0	2364
sl@0	2365	9/30/96 (bug fix) Made EOF sticky on Windows sockets, so that fileevent
sl@0	2366	readable will fire repeatedly until the socket is closed. Previously the
sl@0	2367	fileevent fired only once. This could lead to never-closed connections if
sl@0	2368	the Tcl script in the fileevent wasn't closing the socket immediately. (JL)
sl@0	2369
sl@0	2370	10/2/96 (new feature) Improved the package loader:
sl@0	2371	- Added new variable tcl_pkgPath, which holds the default
sl@0	2372	directories under which packages are normally installed (each
sl@0	2373	package goes in a separate subdirectory of a directory in
sl@0	2374	$tcl_pkgPath). These directories are included in auto_path by
sl@0	2375	default.
sl@0	2376	- Changed the package auto-loader to look for pkgIndex.tcl files
sl@0	2377	not only in the auto_path directories but also in their immediate
sl@0	2378	children. This should make it easier to install and uninstall
sl@0	2379	packages (don't have to change auto_path or merge pkgIndex.tcl
sl@0	2380	files). (JO)
sl@0	2381
sl@0	2382	10/3/96 (bug fix) Changed tclsh to look for tclshrc.tcl instead of
sl@0	2383	tclsh.rc on startup under Windows. This is more consistent with wish and
sl@0	2384	uses the right extension. (SS)
sl@0	2385	* POTENTIAL INCOMPATIBILITY *
sl@0	2386
sl@0	2387	10/8/96 (bug fix) Convertclock does not parse 24-hour times of the
sl@0	2388	form "hhmm" correctly when hour = 00. In the parse code, hour must be
sl@0	2389	>= 100 for minutes to be non-zero. Thanks to Lint LaCour for this
sl@0	2390	bug fix. (RJ)
sl@0	2391
sl@0	2392	10/11/96 (bug fix) Under Windows, the pid command returned the process
sl@0	2393	handle instead of the process id. (SS)
sl@0	2394
sl@0	2395	----------------- Released 7.6, 10/16/96 -----------------------
sl@0	2396
sl@0	2397	10/29/96 (bug fix) Under Windows, sockets would consume 100% CPU time after
sl@0	2398	the first accept(), due to a typo. (JL)
sl@0	2399
sl@0	2400	10/29/96 (bug fix) Incorrect refcount management caused standard channels
sl@0	2401	not to get deleted at process exit or DLL unload time, causing a memory
sl@0	2402	leak of upwards of 20K each time. (JL)
sl@0	2403
sl@0	2404	11/7/96 (bug fix) Auto-exec didn't work on file names that contained
sl@0	2405	spaces. (JO)
sl@0	2406
sl@0	2407	11/8/96 (bug fix) Fixed core dump that would occur if more than one call
sl@0	2408	to Tcl_DeleteChannelHandler was made to delete a given channel handler. (JL)
sl@0	2409
sl@0	2410	11/8/96 (bug fix) Fixed test for return value in Tcl_Seek and Tcl_SeekCmd
sl@0	2411	to only treat -1 as error, instead of all negative numbers. (JL)
sl@0	2412
sl@0	2413	11/12/96 (bug fix) Do not blocking waiting for processes at the end of a
sl@0	2414	pipe during exit cleanup. (JL)
sl@0	2415
sl@0	2416	11/12/96 (bug fix) If we are in exit cleanup, do not close the system level
sl@0	2417	file descriptors 0, 1 and 2. Previously they were being closed which is
sl@0	2418	incorrect, in the embedded case. This led to weird behavior for programs
sl@0	2419	that want to interpose on I/O through the standard file descriptors (e.g.
sl@0	2420	Netscape Navigator). (JL)
sl@0	2421
sl@0	2422	11/15/96 (bug fix) Fixed core dump on Windows sockets due to dependency on
sl@0	2423	deletion order at exit. Now all socket functions check to see if sockets
sl@0	2424	are (still) initialized, before calling through function pointers. Before,
sl@0	2425	they would call and might end up calling unloaded object code. (JL)
sl@0	2426
sl@0	2427	11/15/96 (bug fix) Fixed core dump in Windows socket initialization routine
sl@0	2428	if sockets were not installed on the system. Before, it was not properly
sl@0	2429	checking the result of attempting to load the socket DLL, so it would call
sl@0	2430	through uninitialized function pointers. (JL)
sl@0	2431
sl@0	2432	11/15/96 (bug fix) Fixed memory leak in Windows sockets which left socket
sl@0	2433	DLL handle open and could hold the socket DLL in memory uneccessarily,
sl@0	2434	until a reboot. (JL)
sl@0	2435
sl@0	2436	12/4/96 (bug fix) Fixed bug in Macintosh socket code that could result
sl@0	2437	in lost data if a client was closed too soon after sending data. (RJ)
sl@0	2438
sl@0	2439	12/17/96 (bug fix) Fixed deadlock bug in Windows sockets due to losing an
sl@0	2440	event. This was happening because of an interaction between buffering and
sl@0	2441	nonblocking mode on sockets. Now switched to sockets being blocking by
sl@0	2442	default, so we are also no longer emulating blocking through a private
sl@0	2443	event loop. (JL)
sl@0	2444
sl@0	2445	1/21/97 (performance bug fix) Client TCP connections were slow to create
sl@0	2446	because getservbyname was always called on the port. Now this is only
sl@0	2447	done if Tcl_GetInt fails. (BW)
sl@0	2448
sl@0	2449	1/21/97 (configuration fix) Made it possible to override TCL_PACKAGE_PATH
sl@0	2450	during make. Previously it was only set during autoconf process.
sl@0	2451
sl@0	2452	1/29/97 (bug fix) Fixed some problems with the clock command that
sl@0	2453	impacted how dates were scaned after the year 2000. (RJ)
sl@0	2454
sl@0	2455	----------------- Released 7.6p2, 1/31/97 -----------------------
sl@0	2456
sl@0	2457	2/5/97 (bug fix) Fixed a bug where in CR-LF translation mode, \r bytes
sl@0	2458	in the input stream were not being handled correctly. (JL)
sl@0	2459
sl@0	2460	2/24/97 (bug fix) Fix bug with exec under Win32s not being able to create
sl@0	2461	stderr file which caused all execs to fail. Fixed temp file leak under
sl@0	2462	Win32s. Fixed optional parameter bug with SearchPath that only happened
sl@0	2463	under Win32s 1.25. (CCS)
sl@0	2464
sl@0	2465	----------------------------------------------------------
sl@0	2466	Changes for Tcl 7.6 go above this line.
sl@0	2467	Changes for Tcl 7.7 go below this line.
sl@0	2468	----------------------------------------------------------
sl@0	2469
sl@0	2470	5/8/96 (new feature) Added Tcl_Ungets C API for putting a sequence of bytes
sl@0	2471	into a channel's input buffer. This can be used for "push" model channels
sl@0	2472	where the input is obtained via callbacks instead of by request of the
sl@0	2473	generic IO code. No Tcl procedure yet. (JL)
sl@0	2474
sl@0	2475	11/15/96 (new feature) Implemented hidden commands. New C APIs:
sl@0	2476	Tcl_HideCommand -- hides an existing exposed command.
sl@0	2477	Tcl_ExposeCommand -- exposes an existing hidden command.
sl@0	2478	New tcl APIs:
sl@0	2479	interp invokehidden -- invokes a hidden command in a slave.
sl@0	2480	interp hide -- hides an existing exposed command.
sl@0	2481	interp expose -- exposes an existing hidden command.
sl@0	2482	interp hidden -- returns a list of hidden commands.
sl@0	2483	The implementation of Safe Tcl now uses the new hidden commands facility
sl@0	2484	to implement the safe base, instead of deleting the commands from a safe
sl@0	2485	interpreter. (JL)
sl@0	2486
sl@0	2487	11/15/96 (new feature) Implemented the safe base, a mechanism for
sl@0	2488	installing and requesting security policies, purely in Tcl code. Overloads
sl@0	2489	the package command to also allow an interpreter to "require" a policy. The
sl@0	2490	following new library commands are provided:
sl@0	2491	tcl_safeCreateInterp -- creates a slave an initializes the
sl@0	2492	policy mechanism.
sl@0	2493	tcl_safeInitInterp -- initializes an existing slave with the
sl@0	2494	policy mechanism.
sl@0	2495	tcl_safeDeleteInterp -- deletes a slave and deinitializes the
sl@0	2496	policy mechanism.
sl@0	2497	Added a new file to the library, safeinit.tcl, to hold implementation. (JL)
sl@0	2498	On 7/9/97, removed the policy loading mechanism from the Safe Base. Left
sl@0	2499	only the Safe Base aliases dealing with auto-loading and source. (JL)
sl@0	2500
sl@0	2501	12/6/96 (new feature) Implemented Tcl_Finalize, an API that should be
sl@0	2502	called by a process when it is done using Tcl. This API runs all the exit
sl@0	2503	handlers to allow them to clean up resources etc. (JL)
sl@0	2504
sl@0	2505	12/17/96 (new feature) Add an http Tcl script package to the Tcl library.
sl@0	2506	This package implements the client side of HTTP/1.0; the GET, HEAD,
sl@0	2507	and POST requests. (BW)
sl@0	2508
sl@0	2509	1/21/97 (new feature) Added a "marktrusted" subcommand to the "interp" and
sl@0	2510	to the interpreter object command. It removes the "safe" mark on an
sl@0	2511	interpreter and disables hard-wired checks for safety in the C sources. (JL)
sl@0	2512
sl@0	2513	1/21/97 (removed feature) Removed "vwait" from set of commands available in
sl@0	2514	a safe interpreter. (JL)
sl@0	2515
sl@0	2516	2/11/97 (new feature, bug fix) http package. Added -accept to http_config
sl@0	2517	so you can set the Accept header. Added -handler option to http_get so
sl@0	2518	you can supply your own data handler. Also fixed POST operation to
sl@0	2519	set the correct MIME type on the request. (BW)
sl@0	2520
sl@0	2521	----------------------------------------------------------
sl@0	2522	Changes for Tcl 7.7 go above this line.
sl@0	2523	Changes for Tcl 8.0 go below this line.
sl@0	2524	----------------------------------------------------------
sl@0	2525
sl@0	2526	9/17/96 (bug fix) Using "upvar" it was possible to turn an array element
sl@0	2527	into an array itself. Changed to disallow this; it was quirky and didn't
sl@0	2528	really work correctly anyway. (JO)
sl@0	2529
sl@0	2530	10/21/96 (new feature) The core of the Tcl interpreter has been replaced
sl@0	2531	with an on-the-fly compiler that translates Tcl scripts to bytecoded
sl@0	2532	instructions; a new interpreter then executes the bytecodes. The compiler
sl@0	2533	introduces only a few minor changes at the level of Tcl scripts. The biggest
sl@0	2534	changes are to expressions and lists.
sl@0	2535	- A second level of substitutions is no longer done for expressions.
sl@0	2536	This substantially improves their execution time. This means that
sl@0	2537	the expression "$x*4" produces a different result than in the past
sl@0	2538	if x is "$y+2". Fortunately, not much code depends on the old
sl@0	2539	two-level semantics. Some expressions that do, such as
sl@0	2540	"expr [join $list +]" can be recoded to work in Tcl8.0 by adding
sl@0	2541	an eval: e.g., "eval expr [join $list +]".
sl@0	2542	- Lists are now completely parsed on the first list operation to
sl@0	2543	create a faster internal representation. In the past, if you had a
sl@0	2544	misformed list but the erroneous part was after the point you
sl@0	2545	inserted or extracted an element, then you never saw an error.
sl@0	2546	In Tcl8.0 an error will be reported. This should only effect
sl@0	2547	incorrect programs that took advantage of behavior of the old
sl@0	2548	implementation that was not documented in the man pages.
sl@0	2549	Other changes to Tcl scripts are discussed in the web page at
sl@0	2550	http://www.scriptics.com/doc/compiler.html. (BL)
sl@0	2551	* POTENTIAL INCOMPATIBILITY *
sl@0	2552
sl@0	2553	10/21/96 (new feature) In earlier versions of Tcl, strings were used as a
sl@0	2554	universal representation; in Tcl 8.0 strings are replaced with Tcl_Obj
sl@0	2555	structures ("objects") that can hold both a string value and an internal
sl@0	2556	form such as a binary integer or compiled bytecodes. The new objects make it
sl@0	2557	possible to store information in efficient internal forms and avoid the
sl@0	2558	constant translations to and from strings that occurred with the old
sl@0	2559	interpreter. There are new many new C APIs for managing objects. Some of the
sl@0	2560	new library procedures for objects (such as Tcl_EvalObj) resemble existing
sl@0	2561	string-based procedures (such as Tcl_Eval) but take advantage of the
sl@0	2562	internal form stored in Tcl objects for greater speed. Other new procedures
sl@0	2563	manage objects and allow extension writers to define new kinds of objects.
sl@0	2564	See the manual entries doc/Obj.3 (BL)
sl@0	2565
sl@0	2566	10/24/96 (bug fix) Fixed memory leak on exit caused by some IO related
sl@0	2567	data structures not being deallocated on exit because their refcount was
sl@0	2568	artificially boosted. (JL)
sl@0	2569
sl@0	2570	10/24/96 (bug fix) Fixed core dump in Tcl_Close if called with NULL
sl@0	2571	Tcl_Channel. (JL)
sl@0	2572
sl@0	2573	11/19/96 (new feature) Added library procedures for finding word
sl@0	2574	breaks in strings in a platform specific manner. See the library.n
sl@0	2575	manual entry for more information. (SS)
sl@0	2576
sl@0	2577	11/22/96 (feature improvements) Added support for different levels of
sl@0	2578	tracing during bytecode compilation and execution. This should help in
sl@0	2579	tracking down suspected problems with the compiler or with converting
sl@0	2580	existing code to use Tcl8.0. Two global Tcl variables, traceCompile
sl@0	2581	and traceExec, can be set to generate tracing information in stdout:
sl@0	2582	- traceCompile: 0 no tracing (default)
sl@0	2583	1 trace compilations of top level commands and procs
sl@0	2584	2 trace and display instructions for all compilations
sl@0	2585	- traceExec: 0 no tracing
sl@0	2586	1 trace only calls to Tcl procs
sl@0	2587	2 trace invocations of all commands including procs
sl@0	2588	3 detailed trace showing the result of each instruction
sl@0	2589	traceExec >= 2 provides a one line summary of each called command and
sl@0	2590	its arguments. Commands that have been "compiled away" such as set are
sl@0	2591	not shown. (BL)
sl@0	2592
sl@0	2593	11/30/96 (bug fix) The command "info nameofexecutable" could sometimes
sl@0	2594	return the name of a directory. (JO)
sl@0	2595
sl@0	2596	11/30/96 (feature improvements) Changed the code in library/init.tcl
sl@0	2597	that reads in pkgIndex.tcl so that (a) it reads the files from child
sl@0	2598	directories before those in the parent, so that the parent gets
sl@0	2599	precedence, and (b) it doesn't quit if there is an error in a
sl@0	2600	pkgIndex.tcl file; instead, it prints an error message on standard
sl@0	2601	error and continues. (JO)
sl@0	2602
sl@0	2603	10/5/96 (feature improvements) Partial implementation of binary string
sl@0	2604	support: the ability for Tcl string values to contain embedded null bytes.
sl@0	2605	Changed the Tcl object-based APIs to take a byte pointer and length pair
sl@0	2606	instead of a null-terminated C string. Modified several object type managers
sl@0	2607	to support binary strings but not, for example, the list type manager.
sl@0	2608	Existing string-based C APIs are unchanged and will truncate binary
sl@0	2609	strings. Compiled scripts containing nulls are also truncated. (BL)
sl@0	2610
sl@0	2611	12/12/96 (feature change) Removed the commands "cp", "mkdir", "mv",
sl@0	2612	"rm", and "rmdir" from the Macintosh version of Tcl. They were never
sl@0	2613	officially supported and their functionality is now available via
sl@0	2614	the file command. (RJ)
sl@0	2615
sl@0	2616	----------------- Released 8.0a1, 12/20/96 -----------------------
sl@0	2617
sl@0	2618	1/7/97 (bug fix) Under Windows, "file stat c:" was returning error instead
sl@0	2619	of stat for current dir on c: drive.
sl@0	2620
sl@0	2621	1/10/97 (new feature) Added Tcl_GetIndexFromObj procedure for quick
sl@0	2622	lookups of keyword arguments. (JO)
sl@0	2623
sl@0	2624	1/12/97 (new feature) Serial IO channel drivers for Windows and Unix,
sl@0	2625	available by using Tcl open command to open pseudo-files like "com1:" or
sl@0	2626	"/dev/ttya". New option to Tcl fconfigure command for serial files:
sl@0	2627	"-mode baud,parity,data,stop" to specify baud rate, parity, data bits, and
sl@0	2628	stop bits. Serial IO is not yet available on Mac.
sl@0	2629
sl@0	2630	1/16/97 (feature change) Restored the Tcl7.x "two level substitution
sl@0	2631	semantics" for expressions. Expressions not enclosed in braces are
sl@0	2632	implemented, in general, by calling the expr command procedure
sl@0	2633	(Tcl_ExprObjCmd) at runtime after the Tcl interpreter has already done a
sl@0	2634	first round of substitutions. This is slow (about Tcl7.x speed) because new
sl@0	2635	code for the expression is generally compiled each time. However, if the
sl@0	2636	expression has only variable substitutions (and not command substitutions),
sl@0	2637	"optimistic" fast code is generated inline. This inline code will fail if a
sl@0	2638	second round of substitutions is needed (i.e., if the value of a substituted
sl@0	2639	variable itself requires more substitutions). The optimistic code will
sl@0	2640	catch the error and back off to call the slower but guaranteed correct
sl@0	2641	expr command procedure. (BL)
sl@0	2642
sl@0	2643	1/16/97 (feature improvements) Added Tcl_ExprLongObj and Tcl_ExprDoubleObj
sl@0	2644	to round out expression-related procedures. (BL)
sl@0	2645
sl@0	2646	1/16/97 (feature change) Under Windows, at startup the environment variables
sl@0	2647	"path", "comspec", and "windir" in any capitalization are converted
sl@0	2648	automatically to upper case. The PATH variable could be spelled as path,
sl@0	2649	Path, PaTh, etc. and it makes programming rather annoying. All other
sl@0	2650	environment variables are left alone. (CS)
sl@0	2651
sl@0	2652	1/20/97 (new features) Rewrote the "lsort" command:
sl@0	2653	- The new version is based on reentrant merge sort code provided
sl@0	2654	by Richard Hipp, so it eliminates the reentrancy and stability
sl@0	2655	problems with the old qsort-based implementation.
sl@0	2656	- The new version supports a -dictionary option for sorting, and
sl@0	2657	it also supports a -index option for sorting lists using one
sl@0	2658	element for comparison.
sl@0	2659	- The new version is an object command, so it works well with the
sl@0	2660	Tcl compiler, especially in conjunction with the new -index
sl@0	2661	option. When the -index option is used, this version of lsort
sl@0	2662	is more than 100 times faster than the Tcl 7.6 lsort, which had
sl@0	2663	to use the -command option to get the same effect. (JO)
sl@0	2664
sl@0	2665	1/20/97 (feature improvements) Added the improved debugging support for Tcl
sl@0	2666	objects prototyped by Karl Lehenbauer <karl@hammer1.ops.NeoSoft.com>.
sl@0	2667	If TCL_MEM_DEBUG is defined, the object creation calls use Tcl_DbCkalloc
sl@0	2668	directly in order to record the caller's source file name and line
sl@0	2669	number. (BL)
sl@0	2670
sl@0	2671	1/21/97 (removed feature) Desupported the tcl_precision variable: if
sl@0	2672	set, it is ignored. Tcl now uses the full 17 digits of precision when
sl@0	2673	converting real numbers to strings (with the new object system real
sl@0	2674	numbers are rarely converted to strings so there is no efficiency
sl@0	2675	disadvantage to printing all 17 digits; the new scheme improves
sl@0	2676	accuracy and simplifies several APIs). (JO)
sl@0	2677	* POTENTIAL INCOMPATIBILITY *
sl@0	2678
sl@0	2679	1/21/97 (feature change) Removed the "interp" argument for the
sl@0	2680	procedures Tcl_GetStringFromObj, Tcl_StringObjAppend, and
sl@0	2681	Tcl_StringObjAppendObj. Also removed the "interp" argument for
sl@0	2682	the updateStringProc procedure in Tcl_ObjType structures. With
sl@0	2683	the tcl_precision changes above, these are no longer needed. (JO)
sl@0	2684	* POTENTIAL INCOMPATIBILITY with Tcl 8.0a1, but not with Tcl 7.6 *
sl@0	2685
sl@0	2686	1/22/97 (bug fix) Fixed http.tcl so that http_reset does not result in
sl@0	2687	an extra call to the command callback. In addition, if the transaction
sl@0	2688	gets a premature eof, the state(status) is "eof", not "ok". (BW)
sl@0	2689
sl@0	2690	----------------- Released 8.0a2, 1/24/97 -----------------------
sl@0	2691
sl@0	2692	1/29/97 (feature change) Changed how two digit years are parsed in the
sl@0	2693	clock command. The old interface just added 1900 which will seem
sl@0	2694	broken by the year 2000. The new scheme follows the POSIX standard
sl@0	2695	and treats dates 70-99 as 1970-1999 and dates 00-38 as 2000-2038. All
sl@0	2696	other two digit dates are undefined. (RJ)
sl@0	2697	* POTENTIAL INCOMPATIBILITY *
sl@0	2698
sl@0	2699	2/4/97 (bug fix) Fixed bug in clock code that dealt with relative
sl@0	2700	dates. Using the relative month code you could get an invalid date
sl@0	2701	because it jumped into a non-existant day. (For example, Jan 31
sl@0	2702	to Feb 31.) The code now will return the last valid day of the
sl@0	2703	month in these situations. Thanks to Hume Smith for sending in
sl@0	2704	this bug fix. (RJ)
sl@0	2705
sl@0	2706	2/10/97 (feature change) Eliminated Tcl_StringObjAppend and
sl@0	2707	Tcl_StringObjAppendObj procedures, replaced them with Tcl_AppendToObj
sl@0	2708	and Tcl_AppendStringsToObj procedures. Added new procedure
sl@0	2709	Tcl_SetObjLength. (JO)
sl@0	2710	* POTENTIAL INCOMPATIBILITY with Tcl 8.0a2, but not with Tcl 7.6 *
sl@0	2711
sl@0	2712	2/10/97 (new feature) Added Tcl_WrongNumArgs procedure for generating
sl@0	2713	error messages about incorrect number of arguments. (JO)
sl@0	2714
sl@0	2715	2/11/97 (new feature, bug fix) http package. Added -accept to http_config
sl@0	2716	so you can set the Accept header. Added -handler option to http_get so
sl@0	2717	you can supply your own data handler. Also fixed POST operation to
sl@0	2718	set the correct MIME type on the request. (BW)
sl@0	2719
sl@0	2720	2/22/97 (bug fix) Fixed bug that caused $tcl_platform(osVersion) to be
sl@0	2721	computed incorrectly under AIX. (JO)
sl@0	2722
sl@0	2723	2/25/97 (new feature, feature change) Added support for both int and long
sl@0	2724	integer objects. Added Tcl_NewLongObj/Tcl_GetLongFromObj/Tcl_SetLongFromObj
sl@0	2725	procedures and renamed the Tcl_Obj internalRep intValue member to
sl@0	2726	longValue. Tcl_GetIntFromObj now checks for integer values too large to
sl@0	2727	represent as non-long integers. Changed Tcl_GetAllObjTypes to
sl@0	2728	Tcl_AppendAllObjTypes. (BL)
sl@0	2729
sl@0	2730	3/5/97 (new feature) Added new Tcl_SetListObj procedure to round out
sl@0	2731	collection of procedures that set the type and value of existing Tcl
sl@0	2732	objects. (BL)
sl@0	2733
sl@0	2734	3/6/97 (new feature) Added -global flag for interp invokehidden. (JL)
sl@0	2735
sl@0	2736	3/6/97 (new feature, feature change) Added isNativeObjectProc field to the
sl@0	2737	Tcl_CmdInfo structure to indicate (when 1) if the command has an
sl@0	2738	object-based command procedure. Removed the nameLength arg from
sl@0	2739	Tcl_CreateObjCommand since command names can't contain null characters. (BL)
sl@0	2740
sl@0	2741	3/6/97 (bug fix) Fixed bug in "unknown" procedure that caused auto-
sl@0	2742	loading to fail on commands whose names begin with digits. (JO)
sl@0	2743
sl@0	2744	3/7/97 (bug fix) Auto-loading now works in Safe Base. Safe interpreters
sl@0	2745	only accept the Version 2 and onwards tclIndex files. (JL)
sl@0	2746
sl@0	2747	3/13/97 (bug fix) Fixed core dump due to interaction between aliases and
sl@0	2748	hidden commands. Bug found by Lindsay Marshall. (JL)
sl@0	2749
sl@0	2750	3/14/97 (bug fix) Fixed mac bugs relating to time. The -gmt option
sl@0	2751	now adjusts the time in the correct direction. (Thanks to Ed Hume for
sl@0	2752	reporting a fix to this problem.) Also fixed file "mtime" etc. to
sl@0	2753	return times from GMT rather than local time zone. (RJ)
sl@0	2754
sl@0	2755	3/18/97 (feature change) Declaration of objv in Tcl_ObjCmdProc function
sl@0	2756	changed from "Tcl_Obj objv[]" to "Tcl_Obj CONST objv[]". All Tcl object
sl@0	2757	commands changed to use new declaration of objv. Naive translation of
sl@0	2758	string-based command procs to object-based command procs could very easily
sl@0	2759	have yielded code where the contents of the objv array were changed. This
sl@0	2760	is not a problem with string-based command procs, but doing something as
sl@0	2761	simple as objv[2] = objv[3] would corrupt the runtime stack and cause Tcl to
sl@0	2762	crash. Introduced CONST in declaration of objv so that attempted assignment
sl@0	2763	of new pointer values to elements of the objv array will be caught by the
sl@0	2764	compiler. (CCS)
sl@0	2765	* POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 *
sl@0	2766
sl@0	2767	3/19/97 (bug fix) Fixed panic due to object sharing. The root cause was
sl@0	2768	that old code was using Tcl_ResetResult instead of Tcl_ResetObjResult. (JL)
sl@0	2769
sl@0	2770	3/20/97 (new feature) Added a new subcommand for the file
sl@0	2771	command. file attributes filename can give a list of platform-specific
sl@0	2772	options (such as file/creator type on the Mac, permissions on Unix) or
sl@0	2773	set the values of them. Added a new subcommand for the file
sl@0	2774	command. file nativename name gives back the platform-specific form
sl@0	2775	for the file. This is useful when the filename is needed to pass to
sl@0	2776	the OS, such as exec under Windows 95 or AppleScript on the Mac. For
sl@0	2777	more info, see file.n. (SRP)
sl@0	2778
sl@0	2779	3/24/97 (removed feature) Removed the tcl_safePolicyPath procedure. Now
sl@0	2780	the policy path is computed from the auto_path by appending the directory
sl@0	2781	'policies' to each element. Also fixed several bugs in automatic tracking
sl@0	2782	of auto_path by computed policy path. (JL)
sl@0	2783	* POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 *
sl@0	2784
sl@0	2785	4/8/97 (new feature) If the variable whose name is passed to lappend doesn't
sl@0	2786	already exist, and there are no value arguments, lappend now creates the
sl@0	2787	variable with an empty value instead of returning an error. Change suggested
sl@0	2788	by Tom Tromey. (BL)
sl@0	2789
sl@0	2790	4/9/97 (feature change) Changed the name of the TCL_PART1_NOT_PARSED flag to
sl@0	2791	TCL_PARSE_PART1. (BL)
sl@0	2792	* POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 *
sl@0	2793
sl@0	2794	4/10/97 (bug fixes) Fixed various compilation-related bugs:
sl@0	2795	- "UpdateStringOfCmdName should never be invoked" panic.
sl@0	2796	- Bad code generated for expressions not in {}'s inside catch commands.
sl@0	2797	- Segmentation fault in some command procedures when two argument
sl@0	2798	object pointers refer to the same object.
sl@0	2799	- Second level of substitutions were never done for expressions not
sl@0	2800	in {}'s that consist of a single variable reference: e.g.,
sl@0	2801	"set x 27; set bool {$x}; if $bool {puts foo}" would fail with error.
sl@0	2802	- Bad code generated when code storage was grown while compiling some
sl@0	2803	expressions: ones with compilation errors or consisting of only a
sl@0	2804	variable reference.
sl@0	2805	- Bugs involving multiple interpreters: wasn't checking that a
sl@0	2806	procedure's code was compiled for the same interpreter as the one
sl@0	2807	executing it, and didn't invalidate code on hidden-exposed command
sl@0	2808	transitions.
sl@0	2809	- "Bad stack top" panic when executing scripts that require a huge
sl@0	2810	amount of stack space.
sl@0	2811	- Incorrect sharing of code for procedure bodies, and procedure code
sl@0	2812	deallocated before last execution of the procedure finished.
sl@0	2813	- Fixed compilation of expression words in quotes. For example,
sl@0	2814	if "0 < 3" {puts foo}.
sl@0	2815	- Fixed performance bug in array set command with large assignments.
sl@0	2816	- Tcl_SetObjLength segmentation fault setting length of empty object.
sl@0	2817	- If Tcl_SetObjectResult was passed the same object as the interpreter's
sl@0	2818	result object, it freed the object instead of doing nothing. Bug fix
sl@0	2819	by Michael J. McLennan.
sl@0	2820	- Tcl_ListObjAppendList inserted elements from the wrong list. Bug fix
sl@0	2821	by Michael J. McLennan.
sl@0	2822	- Segmentation fault if empty variable list was specified in a foreach
sl@0	2823	command. Bug fix by Jan Nijtmans.
sl@0	2824	- NULL command name was always passed to Tcl_CreateTrace callback
sl@0	2825	procedure.
sl@0	2826	- Wrong string representation generated for the value LONG_MIN.
sl@0	2827	For example, expr 1<<31 printed incorrectly on a 32 bit machine.
sl@0	2828	- "set {a($x)} 1" stored value in wrong variable.
sl@0	2829	- Tcl_GetBooleanFromObj was not checking for garbage after a numeric
sl@0	2830	value.
sl@0	2831	- Garbled "bad operand type" error message when evaluating expressions
sl@0	2832	not surrounded by {}'s. (BL)
sl@0	2833
sl@0	2834	4/16/97 (new feature) The expr command now has the "rand()" and
sl@0	2835	"srand()" functions for getting random numbers in expr. (RJ)
sl@0	2836
sl@0	2837	4/23/97 (bug fix) Fixed core dump in bgerror when the error handler command
sl@0	2838	deletes the current interpreter. Found by Juergen Schoenwald. (JL)
sl@0	2839
sl@0	2840	4/23/97 (feature change) The notifier interfaces have been redesigned
sl@0	2841	to make embedding in applications with external event loops possible.
sl@0	2842	A number of interfaces in the notifier and the channel drivers have
sl@0	2843	changed. Refer to the Notifier.3 and CrtChannel.3 manual entries for
sl@0	2844	more details. (SS)
sl@0	2845	* POTENTIAL INCOMPATIBILITY *
sl@0	2846
sl@0	2847	4/23/97 (removed feature) The Tcl_File interfaces have been removed.
sl@0	2848	The Tcl_CreateFileHandler/Tcl_DeleteFileHandler interfaces now take
sl@0	2849	Unix fd's and are only supported on the Unix platform.
sl@0	2850	Tcl_GetChannelFile has been replaced with Tcl_GetChannelHandle.
sl@0	2851	Tcl_MakeFileChannel now takes a platform specific file handle. (SS)
sl@0	2852	* POTENTIAL INCOMPATIBILITY *
sl@0	2853
sl@0	2854	4/23/97 (removed feature) The modal timeout interface has been

sl@0	2856	* POTENTIAL INCOMPATIBILITY *
sl@0	2857
sl@0	2858	4/23/97 (feature change) Channel drivers are now required to correctly

sl@0	2860	* POTENTIAL INCOMPATIBILITY *
sl@0	2861
sl@0	2862	4/23/97 (new feature) Added the "binary" command for manipulating
sl@0	2863	binary strings. Also, changed the "puts", "gets", and "read" commands
sl@0	2864	to preserve embedded nulls. (SS)
sl@0	2865
sl@0	2866	4/23/97 (new feature) Added tcl_platform(byteOrder) element to the
sl@0	2867	tcl_platform array to identify the native byte order for the current
sl@0	2868	host. (SS)
sl@0	2869
sl@0	2870	4/23/97 (bug fix) Fixed bug in date parsing around year boundaries. (SS)
sl@0	2871
sl@0	2872	4/24/97 (bug fix) In the process of copying a file owned by another user,
sl@0	2873	Tcl was changing the owner of the copy back to the owner of the original
sl@0	2874	file, therefore causing further file operations to fail because the current
sl@0	2875	user didn't own the copy anymore. The owner of the copy is now left as the
sl@0	2876	current user. (CCS)
sl@0	2877
sl@0	2878	4/24/97 (feature change) Under Windows, don't automatically uppercase the
sl@0	2879	environment variable "windir" -- it's supposed to be lower case. (CCS)
sl@0	2880
sl@0	2881	4/29/97 (new feature) Added namespace support based on a namespace
sl@0	2882	implementation by Michael J. McLennan of Lucent Technologies. A namespace
sl@0	2883	encapsulates a collection of commands and variables to ensure that they
sl@0	2884	won't interfere the commands and variables of other namespaces. The global
sl@0	2885	namespace holds all global variables and commands. Additional namespaces are
sl@0	2886	created with the new namespace command. The new variable command lets you
sl@0	2887	create Tcl variables inside a namespace. The names of Tcl variables and
sl@0	2888	commands may now be qualified by the name of the namespace containing them.
sl@0	2889	The key namespace-related commands are summarized below:
sl@0	2890	- namespace ?eval? name arg ?arg...?
sl@0	2891	Used to define the commands and variables in a namespace.
sl@0	2892	Optionally creates the namespace.
sl@0	2893	- namespace export ?-clear? ?pattern pattern...?
sl@0	2894	Specifies which commands are exported from a namespace. These
sl@0	2895	are the ones that can be imported into another namespace.
sl@0	2896	- namespace import ?-force? ?pattern pattern...?
sl@0	2897	Makes the specified commands accessible in the current namespace.
sl@0	2898	- namespace current
sl@0	2899	Returns the name of the current namespace.
sl@0	2900	- variable name ?value? ?name ?value?...?
sl@0	2901	Creates one or more namespace variables. (BTL)
sl@0	2902
sl@0	2903	5/1/97 (bug fix) Under Windows, file times were reported in GMT. Should be
sl@0	2904	reported in local time. (CCS)
sl@0	2905
sl@0	2906	5/2/97 (feature change) Changed the name of the two Tcl variables used for
sl@0	2907	tracing bytecode compilation and execution to tcl_traceCompile and
sl@0	2908	tcl_traceExec respectively. These variables are now documented in the
sl@0	2909	tclvars man page. (BL)
sl@0	2910
sl@0	2911	5/5/97 (new feature) Support "end" as the index for "lsort -index". (BW)
sl@0	2912
sl@0	2913	5/5/97 (bug fixes) Cleaned up the way the http package resets connections (BW)
sl@0	2914
sl@0	2915	5/8/97 (feature change) Newly created Tcl objects now have a reference count
sl@0	2916	of zero instead of one. This simplifies C code that stores newly created
sl@0	2917	objects in Tcl variables or in data structures such as list objects. That C
sl@0	2918	code must increment the new object's reference count since the variable or
sl@0	2919	data structure will contain a long-term reference to the object. Formerly,
sl@0	2920	when new objects started out with reference count one, it was necessary to
sl@0	2921	decrement the new object's reference count after the store to make sure it
sl@0	2922	was left with the correct value; this is no longer necessary. (BL)
sl@0	2923
sl@0	2924	5/9/97 (new feature) Added the Tcl_GetsObj interface that takes an
sl@0	2925	object reference instead of a dynamic string (as in Tcl_Gets). (SS)
sl@0	2926
sl@0	2927	5/12/97 (new feature) Added Tcl_CreateAliasObj and Tcl_GetAliasObj C APIs
sl@0	2928	to allow an alias command to be created with a vector of Tcl_Obj structures
sl@0	2929	and to get the vector back later. (JL)
sl@0	2930
sl@0	2931	5/12/97 (feature change) Changed Tcl_ExposeCommand and Tcl_HideCommand to
sl@0	2932	leave an object result instead of a string result. (JL)
sl@0	2933
sl@0	2934	5/14/97 (feature change) Improved the handling of the interpreter result.
sl@0	2935	This is still either an object or a string, but the two values are now kept
sl@0	2936	consistent unless some C code reads or writes interp->result directly. See
sl@0	2937	the SetResult man page for details. Removed the Tcl_ResetObjResult
sl@0	2938	procedure. (BL)
sl@0	2939	* POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 *
sl@0	2940
sl@0	2941	5/16/97 (new feature) Added "fcopy" command to move data between
sl@0	2942	channels. Refer to the manual page for more information. Removed the
sl@0	2943	"unsupported0" command since it is obsolete now. (SS)
sl@0	2944
sl@0	2945	5/16/97 (new feature) Added Tcl_GetStringResult procedure to allow programs
sl@0	2946	to get an interpreter's result as a string. If the result was previously set
sl@0	2947	to an object, this procedure will convert the object to a string. Use of
sl@0	2948	Tcl_GetStringResult is intended to replace direct access to interp->result,
sl@0	2949	which is not safe. (BL)
sl@0	2950
sl@0	2951	5/20/97 (new features) Fixed "fcopy" to return the number of bytes
sl@0	2952	transferred in the blocking case. Updated the http package to use
sl@0	2953	fcopy instead of unsupported0. Added -timeout and -handler options to
sl@0	2954	http_get. http_get is now blocking by default. It is only non-blocking
sl@0	2955	if you supply a -command argument. (BW)
sl@0	2956
sl@0	2957	5/22/97 (bug fix) Fixed several bugs in the "lsort" command having to do
sl@0	2958	with the -dictionary option and the presence of numbers embedded in the
sl@0	2959	strings. (JO)
sl@0	2960
sl@0	2961	----------------- Released 8.0b1, 5/27/97 -----------------------
sl@0	2962
sl@0	2963	6/2/97 (bug fix) Fixed bug in startup code that caused a problem in
sl@0	2964	finding the library files when they are installed in a directory
sl@0	2965	containing a space in the name. (SS)
sl@0	2966
sl@0	2967	6/2/97 (bug fix) Fixed bug in Unix notifier where the select mask was
sl@0	2968	not being cleared under some circumstances. (SS)
sl@0	2969
sl@0	2970	6/4/97 (bug fix) Fixed bug that prevented creation of Tk widgets in
sl@0	2971	namespaces. Tcl_CreateObjCommand and Tcl_CreateCommand now always create
sl@0	2972	commands in the global namespace unless the command names are qualified. Tcl
sl@0	2973	procedures continue to be created in the current namespace by default. (BL)
sl@0	2974
sl@0	2975	6/6/97 (new features) Added new namespace API procedures
sl@0	2976	Tcl_AppendExportList and Tcl_Export to allow C code to get and set a
sl@0	2977	namespace's export list. (BL)
sl@0	2978
sl@0	2979	6/11/97 (new feature) Added Tcl_ConcatObj. This object-based routine
sl@0	2980	parallels the string-based routine Tcl_Concat. (SRP)
sl@0	2981
sl@0	2982	6/11/97 (new feature) Added Tcl_SetObjErrorCode. This object-based
sl@0	2983	routines parallels the string-based routine Tcl_SetErrorCode. (SRP)
sl@0	2984
sl@0	2985	6/12/97 (bug fix) Fix the "unknown" procedure so that wish under Windows
sl@0	2986	will exec an external program, instead of always complaining "console1 not
sl@0	2987	opened for writing". (CCS)
sl@0	2988
sl@0	2989	6/12/97 (bug fix) Fixed core dump experienced by the following simple
sl@0	2990	script:
sl@0	2991	interp create x
sl@0	2992	x alias exec exec
sl@0	2993	interp delete x
sl@0	2994	This panic was caused by not installing the new CmdDeleteProc when exec
sl@0	2995	got redefined by the alias creation step. Reported by Lindsay Marshal (JL)
sl@0	2996
sl@0	2997	6/13/97 (new features) Tcl objects newly created by Tcl_NewObj now have a
sl@0	2998	string representation that points to a shared heap string of length 1. (They
sl@0	2999	used to have NULL bytes and typePtr fields. This was treated as a special
sl@0	3000	case to indicate an empty string, but made type manager implementations
sl@0	3001	complex and error prone.) The new procedure Tcl_InvalidateStringRep is used
sl@0	3002	to mark an object's string representation invalid and to free any storage
sl@0	3003	associated with the old string representation. (BL)
sl@0	3004	* POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 *
sl@0	3005
sl@0	3006	6/16/97 (bug fix) Tcl_ScanCountedElement could leave braces unmatched
sl@0	3007	if the string ended with a backslash. (JO)
sl@0	3008
sl@0	3009	6/17/97 (bug fix) Fixed channel event bug where readable events would be
sl@0	3010	lost during recursive events loops if the input buffers contained
sl@0	3011	data. (SS)
sl@0	3012
sl@0	3013	6/17/97 (bug fix) Fixed bug in Windows socket code that didn't
sl@0	3014	reenable read events in the case where an external entity is also
sl@0	3015	reading from the socket. (SS)
sl@0	3016
sl@0	3017	6/18/97 (bug fix) Changed initial setting of the notifier service mode
sl@0	3018	to TCL_SERVICE_NONE to avoid unexpected event handling during
sl@0	3019	initialization. (SS)
sl@0	3020
sl@0	3021	6/19/97 (bug fix/feature change) The command callback to fcopy is now
sl@0	3022	called in case of errors during the background copy. This adds a second,
sl@0	3023	optional argument to the callback that is the error string. The callback
sl@0	3024	in case of errors is required for proper cleanup by the user of fcopy. (BW)
sl@0	3025	* POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 *
sl@0	3026
sl@0	3027	6/19/97 (bug fix) Fixed a panic due to the following four line script:
sl@0	3028	interp create x
sl@0	3029	x alias foo bar
sl@0	3030	x eval rename foo blotz
sl@0	3031	x alias foo {}
sl@0	3032	The problem was that the interp code was not using the actual current name
sl@0	3033	of the command to be deleted as a result of un-aliasing foo. (JL)
sl@0	3034
sl@0	3035	6/19/97 (feature change) Pass interp down to the ChannelOption and
sl@0	3036	driver specific calls so system errors can be differentiated from syntax
sl@0	3037	ones. Changed Tcl_DriverGetOptionProc type. Affects Tcl_GetChannelOption,
sl@0	3038	TcpGetOptionProc, TtyGetOptionProc, etc. (DL)
sl@0	3039	* POTENTIAL INCOMPATIBILITY *
sl@0	3040
sl@0	3041	6/19/97 (new feature) Added Tcl_BadChannelOption for use by by driver
sl@0	3042	specific option procedures (Set and Get) to return a complete and
sl@0	3043	meaningful error message. (DL)
sl@0	3044
sl@0	3045	6/19/97 (bug fixes) If a system call error occurs while doing an
sl@0	3046	fconfigure on tcp or tty/com channel: return the appropriate error
sl@0	3047	message (instead of the syntax error one or none). (Fixed for Unix and
sl@0	3048	most of the Win and Mac drivers). (DL)
sl@0	3049
sl@0	3050	6/20/97 (feature change) Eval is no longer assumed as the subcommand name
sl@0	3051	in namespace commands: you must now write "namespace eval nsName {...}".
sl@0	3052	Abbreviations of namespace subcommand names are now allowed. (BL)
sl@0	3053	* POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 *
sl@0	3054
sl@0	3055	6/20/97 (feature change) Changed the errorInfo traceback message for
sl@0	3056	compilation errors from "invoked from within" to "while compiling". (BL)
sl@0	3057
sl@0	3058	6/20/97 (bug fixes) Fixed various compilation-related bugs:
sl@0	3059	- "UpdateStringOfCmdName should never be called" and
sl@0	3060	"UpdateStringOfByteCode should never be called" panics.
sl@0	3061	- Segfault in TclObjInterpProc getting procedure name after evaluation
sl@0	3062	stack is reallocated (grown).
sl@0	3063	- Could not use ":" at end of variable and command names.
sl@0	3064	- Bad code generated for while and for commands with test expressions
sl@0	3065	enclosed in quotes: e.g., "set i 0; while "$i > 5" {}".
sl@0	3066	- Command trace procedures would crash if they did a Tcl_EvalObj that
sl@0	3067	reallocated the evaluation stack.
sl@0	3068	- Break and continue commands did not reset the interpreter result.
sl@0	3069	- The Tcl_ExprXXX routines, both string- or object-based, always
sl@0	3070	modified the interpreter result even if there was no error.
sl@0	3071	- The argument parsing procedure used by several compile procedures
sl@0	3072	always treated "]" as end of a command: e.g., "set a ]" would fail.
sl@0	3073	- Changed errorInfo traceback message for compilation errors from
sl@0	3074	"invoked from within" to "while compiling".
sl@0	3075	- Problem initializing Tcl object managers during interpreter creation.
sl@0	3076	- Added check and error message if formal parameter to a procedure is
sl@0	3077	an array element. (BL)
sl@0	3078
sl@0	3079	6/23/97 (new feature) Added "registry" package to allow manipulation
sl@0	3080	of the Windows system registry. See manual entry for details. (SS)
sl@0	3081
sl@0	3082	6/24/97 (feature change) Converted http to a package and added the
sl@0	3083	http1.0 subdirectory of the Tcl script library. This means you have
sl@0	3084	to do a "package require http" to use this, as advertised in the man page. (BW)
sl@0	3085	* POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 *
sl@0	3086
sl@0	3087	6/24/97 (bug fix) Ensure that Tcl_Set/GetVar C APIs, when called without
sl@0	3088	TCL_LEAVE_ERR_MSG, don't touch the interp result. (DL)
sl@0	3089
sl@0	3090	6/26/97 (feature change) Changed name of Tcl_ExprStringObj to
sl@0	3091	Tcl_ExprObj. (BL)
sl@0	3092	* POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 *
sl@0	3093
sl@0	3094	----------------- Released 8.0b2, 6/30/97 -----------------------
sl@0	3095
sl@0	3096	7/1/97 (new feature) TCL_BUILD_SHARED flag set in tclConfig.sh
sl@0	3097	when Tcl has been built with --enable-shared. A new tclLibObjs
sl@0	3098	make target, echoing the list of the .o's needed to build a tcl
sl@0	3099	library, is now provided. (DL)
sl@0	3100
sl@0	3101	7/1/97 (feature change) compat/getcwd.c removed and changed the
sl@0	3102	only place where getcwd is used so a new USEGETWD flag selects
sl@0	3103	the use of the replacement "getwd". Adding this flag is recommended
sl@0	3104	for SunOS 4 (because getcwd on SunOS 4 uses a pipe to pwd(1)!). (DL)
sl@0	3105
sl@0	3106	7/7/97 (feature change) The split command now supports binary data (i.e.,
sl@0	3107	null characters in strings). (BL)
sl@0	3108
sl@0	3109	7/7/97 (bug fix) string first returned the wrong result if the first
sl@0	3110	argument string was empty. (BL)
sl@0	3111
sl@0	3112	7/8/97 (bug fix) Fixed core dump in fcopy that could occur when a command
sl@0	3113	callback was supplied and an error or eof condition caused no background
sl@0	3114	activity. A refcount bug triggered a panic in Tcl_ListObjAppendElement. (BW)
sl@0	3115
sl@0	3116	7/8/97 (bug fix) Relaxed the pattern matching on http_get so you do not
sl@0	3117	need a trailing path component. You can now get away with just
sl@0	3118	http_get www.scriptics.com (BW)
sl@0	3119
sl@0	3120	7/9/97 (bug fix) Creating anonymous interpreters no longer smashes existing
sl@0	3121	commands with names similar to the generated name. Previously creating an
sl@0	3122	anonymous interpreter could smash an existing command, now it skips until
sl@0	3123	it finds a command name that isn't being used. (JL)
sl@0	3124
sl@0	3125	7/9/97 (feature change) Removed the policy management mechanism from the
sl@0	3126	Safe Base; left the aliases to source and load modules, and to do a limited
sl@0	3127	form of the "file" command. See entry of 11/15/96. (JL)
sl@0	3128
sl@0	3129	7/9/97 (bug fixes) Fixed various compilation-related bugs:
sl@0	3130	- Line numbers in errorInfo now are the same as those in Tcl7.6 unless
sl@0	3131	there are compilation errors. Compilation error messages now include the
sl@0	3132	entire command in error.
sl@0	3133	- Trailing ::s after namespace names weren't being ignored.
sl@0	3134	- Could not refer to an namespace variable with an empty name using a
sl@0	3135	name of the form "n::". (BL)
sl@0	3136
sl@0	3137	7/9/97 (bug fix) Fixed bug in Tcl_Export that prevented you from exporting
sl@0	3138	from other than the current namespace. (BL)
sl@0	3139
sl@0	3140	7/9/97 (bug fix) env.test was removing env var needed for proper finding
sl@0	3141	of libraries in child process. (DL)
sl@0	3142
sl@0	3143	7/10/97 (bug fixes/new feature) Cleanup in Tcl_MakeSafe. Less information
sl@0	3144	is leaked to safe interps. Error message fixes for interp sub commands.
sl@0	3145	Likewise changes in safealias.tcl; tcl_safeCreateInterp can now be called
sl@0	3146	without argument to generate the slave name (like in interp create). (DL)
sl@0	3147
sl@0	3148	7/10/97 (bug fixes) Bytecode compiler now generates more detailed
sl@0	3149	command location information: subcommands as well as commands now have
sl@0	3150	location information. This means command trace procedures now get the
sl@0	3151	correct source string for each command in their command parameter. (BL)
sl@0	3152
sl@0	3153	7/22/97 (bug fixes) Performance improvement in Safe interpreters
sl@0	3154	handling. Added new mask value to (tclInt.h) Interp.flags record. (DL)
sl@0	3155
sl@0	3156	7/22/97 (bug fix) Fixed panic in 'interp target {} foo'. This bug
sl@0	3157	was present since Tcl 7.6. (JL)
sl@0	3158
sl@0	3159	7/22/97 (bug fix) Fixed bug in compilation of procedures in namespaces: the
sl@0	3160	procedure's namespace must be used to look up compile procedures, not the
sl@0	3161	current namespace. (BL)
sl@0	3162
sl@0	3163	7/22/97 (bug fix) Use of the -channel option of http_get was not setting
sl@0	3164	the end of line translations mode on the channel, so copying binary data
sl@0	3165	with the -channel option was corrupting the result on non-unix platforms. (BW)
sl@0	3166
sl@0	3167	7/22/97 (bug fixes) file commands and ~user (seg fault and other
sl@0	3168	improper returns). (DL)
sl@0	3169
sl@0	3170	7/23/97 (feature change) Reenabled "vwait" in Safe Base. (JL)
sl@0	3171
sl@0	3172	7/23/97 (bug fixes) Fixed two bugs involving read traces on array variables
sl@0	3173	in procedures: trace procedures were sometimes not called, and reading
sl@0	3174	nonexistant array elements didn't create undefined element variables that
sl@0	3175	could later be defined by trace procedures. (BL)
sl@0	3176
sl@0	3177	7/24/97 (bug fix) Windows memory allocation performance was
sl@0	3178	superlinear in some cases. Made the Mac allocator generic and changed
sl@0	3179	both the Mac and Windows platforms to use the new allocator instead of
sl@0	3180	malloc and free. (SS)
sl@0	3181
sl@0	3182	7/24/97 - 8/12/97 (bug fixes/change of features) Completely revamped safe
sl@0	3183	sourcing/loading (see safe.n) to hide pathnames, use virtual
sl@0	3184	paths tokens instead, improved security in several respects and made it
sl@0	3185	more tunable. Multi level interp loading can work too now. Package auto
sl@0	3186	loading now works in safe interps as long as the package directory is in
sl@0	3187	the auto_path (no deep crawling allowed in safe interps). (DL)
sl@0	3188	* POTENTIAL INCOMPATIBILITY with previous alpha and beta releases *
sl@0	3189
sl@0	3190	7/24/97 (bug fixes) Made Tcl_SetVar* and Tcl_NewString* treat a NULL value
sl@0	3191	as an empty string. (This fixes hairy crash case where you would crash
sl@0	3192	because load command for other interps assumed presence of
sl@0	3193	errorInfo...). (DL)
sl@0	3194
sl@0	3195	7/28/97 (bug fix) Fixed pkg_mkIndex to understand namespaces. It will
sl@0	3196	use the export list of a namespace and create auto_index entries for
sl@0	3197	all export commands. Those names are in their fully qualified form in the
sl@0	3198	auto_index. Therefore, I tweaked unknown to try both $cmd and ::$cmd.
sl@0	3199	Also fixed pkg_mkIndex so you can have "package require" commands inside
sl@0	3200	your packages. These commands are ignored, which is mostly ok except
sl@0	3201	when you must load another package before loading yours because of
sl@0	3202	linking dependencies. (BW)
sl@0	3203
sl@0	3204	7/28/97 (bug fix) A variable created by the variable command now persists
sl@0	3205	until the namespace is destroyed or the variable is unset. This is true even
sl@0	3206	if the variable has not been initialized; these variables used to be
sl@0	3207	destroyed if an error occurred when accessing them. In addition, the "info
sl@0	3208	vars" command lists uninitialized namespace variables, while the "info
sl@0	3209	exists" command returns 0 for them. (BL)
sl@0	3210
sl@0	3211	7/29/97 (feature change) Changed the http package to use the ::http
sl@0	3212	namespace. http_get renamed to http::geturl, http_config renamed to
sl@0	3213	http::config, http_formatQuery renamed to http::formatQuery.
sl@0	3214	It now provides the 2.0 version of the package.
sl@0	3215	The 1.0 version is still available with the old names.
sl@0	3216	* POTENTIAL INCOMPATIBILITY with Tcl 8.0b2 but not with Tcl 7.6 *
sl@0	3217
sl@0	3218	7/29/97 (bug fix, new feature) Tcl_Main now uses Tcl objects internally to
sl@0	3219	preserve NULLs in commands and command output. Added new API procedure
sl@0	3220	Tcl_RecordAndEvalObj that resembles Tcl_RecordAndEval but takes an object
sl@0	3221	containing a command. (BL)
sl@0	3222
sl@0	3223	7/30/97 (bug fix) Tcl freed strings in the environ array even if it
sl@0	3224	did not allocate them. (SS)
sl@0	3225
sl@0	3226	7/30/97 (bug fix) If a procedure is renamed into a different namespace, it
sl@0	3227	now executes in the context of that namespace. (BL)
sl@0	3228
sl@0	3229	7/30/97 (bug fix) Prevent renaming of commands into and from namespaces as
sl@0	3230	part of hiding them. (JL)
sl@0	3231
sl@0	3232	7/31/97 (feature change) Moved the history command from C to tcl.
sl@0	3233	This uses the ::history namespace. The "words" and "substitute" options
sl@0	3234	are no longer supported. In addition, the "keep" option without a value
sl@0	3235	returns the current keep limit. There is a new "clear" option.
sl@0	3236	The unknown command now supports !! again. (BW)
sl@0	3237	* POTENTIAL INCOMPATIBILTY *
sl@0	3238
sl@0	3239	7/30/97 (bug fix) Made sure that a slave can not fool the master into
sl@0	3240	hiding the wrong command. Made sure we don't crash in hiding + namespaces
sl@0	3241	issues. (DL)
sl@0	3242
sl@0	3243	8/4/97 (bug fix) Concat, eval, uplevel, and similar commands were
sl@0	3244	incorrectly trimming trailing space characters from their arguments
sl@0	3245	even when the space characters were preceded by a backslash. (JO)
sl@0	3246
sl@0	3247	8/4/97 (bug fix) Removed the hard link between bgerror and tkerror.
sl@0	3248	Only bgerror is supported in tcl core. Tk will still look for a
sl@0	3249	tkerror but using regular tcl code for that feature. (DL)
sl@0	3250	* POTENTIAL INCOMPATIBILTY with code relying on the hard link *
sl@0	3251
sl@0	3252	8/6/97 (bug fix) Reduced size required for compiled bytecodes by using a
sl@0	3253	more compact encoding for the command pc-to-source map. (BL)
sl@0	3254
sl@0	3255	8/6/97 (new feature) Added support for additional compilation and execution
sl@0	3256	statistics when Tcl is compiled with the TCL_COMPILE_STATS flag. (BL)
sl@0	3257
sl@0	3258	8/7/97 (bug fix) Expressions not in {}s that have a comparison operator as
sl@0	3259	the topmost operator must be compiled out-of-line (call the expr cmd at
sl@0	3260	runtime) to properly support expr's two-level substitution semantics. An
sl@0	3261	example is "set a 2; set b {$a}; puts [expr $b == 2]". (BL)
sl@0	3262
sl@0	3263	8/11/97 (bug fix) The catch command would sometimes crash if a variable name
sl@0	3264	was given and the bytecode evaluation stack was grown when executing the
sl@0	3265	argument script. (BL)
sl@0	3266
sl@0	3267	8/12/97 (feature change) Reinstated the variable tcl_precision to control
sl@0	3268	the number of digits used when floating-point values are converted to
sl@0	3269	strings, with default of 12 digits. However, had to make tcl_precision
sl@0	3270	shared among all interpreters (except that safe interpreters can't
sl@0	3271	modify it). This makes the Tcl 8.0 behavior almost identical to 7.6
sl@0	3272	except that the default precision is 12 instead of 6. (JO)
sl@0	3273	* POTENTIAL INCOMPATIBILITY *
sl@0	3274
sl@0	3275	----------------- Released 8.0, 8/18/97 -----------------------
sl@0	3276
sl@0	3277	8/19/97 (bug fix) Minimal fix for glob -nocomplain bugs:
sl@0	3278	"glob -nocomplain unreadableDir/*" was generating an anonymous
sl@0	3279	error. More in depth fixes will come with 8.1. (DL).
sl@0	3280
sl@0	3281	8/20/97 (bug fix) Removed check for FLT_MIN in binary command so
sl@0	3282	underflow conditions are handled by the compiler automatic
sl@0	3283	conversions. (SS)
sl@0	3284
sl@0	3285	8/20/97 (bug fixes) Fixed several compilation-related bugs:
sl@0	3286	- Array cmd wasn't detecting arrays that, while compiled, do not yet
sl@0	3287	exist (e.g., are marked undefined since they haven't been assigned
sl@0	3288	to yet).
sl@0	3289	- The GetToken procedure in tclCompExpr.c wasn't recognizing properly
sl@0	3290	whether an integer token was invalid. For example, "0x$" is not
sl@0	3291	a valid integer.
sl@0	3292	- Performance bug in TclExecuteByteCode: the size of its stack frame
sl@0	3293	was reduced by over 20% by moving errorInfo code elsewhere.
sl@0	3294	- Uninitialized memory read error in tclCompile.c. (BL)
sl@0	3295
sl@0	3296	8/21/97 (bug fix) safe::interpConfigure now behave like Tk widget's
sl@0	3297	configure : it changes only the options you provide and you can get
sl@0	3298	the current value of any single option. New ?-nested boolean? and
sl@0	3299	?-statics boolean? for all safe::interp* commands but we still
sl@0	3300	accept (upward compatibility) the previously defined non valued
sl@0	3301	flags ?-noStatics? and ?-nestedLoadOk?. Improved the documentation. (DL).
sl@0	3302
sl@0	3303	8/22/97 (bug fix) Updated PrintDbl.3 to reflect the fact that the
sl@0	3304	tcl_precision variable is still used and that it is now shared by all
sl@0	3305	interpreters. (BL)
sl@0	3306
sl@0	3307	8/25/97 (bug fix) Fixed array access bug in IllegalExprOperandType
sl@0	3308	procedure in tclExecute.c: it was not properly supporting the \|\| and &&
sl@0	3309	operators. (BL)
sl@0	3310
sl@0	3311	8/27/97 (bug fix) In cases where a channel handler was created with an
sl@0	3312	empty event mask while data was still buffered in the channel, the
sl@0	3313	channel code would get stuck spinning on a timer that would starve
sl@0	3314	idle handlers. This mostly happened in Tk when reading from stdin. (SS)
sl@0	3315
sl@0	3316	9/4/97 (bug fix) Slave interps now inherit the maximum recursion limit
sl@0	3317	of their parent instead of starting back at the default. {nb: this still
sl@0	3318	does not prevent stack overflow by multi-interps recursion or aliasing} (DL)
sl@0	3319
sl@0	3320	9/11/97 (bug fix) An uninitialized variable in Tcl_WaitPid caused
sl@0	3321	pipes to fail to report eof properly under Windows. (SS)
sl@0	3322
sl@0	3323	9/12/97 (bug fix) "exec" was misidentifying some DOS executables as not
sl@0	3324	executable. (CCS)
sl@0	3325
sl@0	3326	9/14/97 (bug fix) Was using the wrong structure in sizeof operation in
sl@0	3327	tclUnixChan.c. (JL)
sl@0	3328
sl@0	3329	9/15/97 (bug fix) Fixed notifier to break out of do-one-event loop if
sl@0	3330	Tcl_WaitForEvent returns 1, so that callers of Tcl_DoOneEvent will get
sl@0	3331	a chance to check whether the event just handled is significant. This
sl@0	3332	affected mainly recursive calls to Tcl_VWaitCmd; these did not get a
sl@0	3333	chance to notice that the variable they were waiting for has been set
sl@0	3334	and thus they didn't terminate the vwait. (JL, DL, SS)
sl@0	3335
sl@0	3336	9/15/97 (bug fix) Alignment problems in "binary format" would cause a
sl@0	3337	crash on some platforms when formatting floating point numbers. (SS)
sl@0	3338
sl@0	3339	9/15/97 (bug fix) Fixed bug in Macintosh socket code. Now passes all
sl@0	3340	tests in socket.test that are not platform specific. (Thanks to Mark
sl@0	3341	Roseman for the pointer on the fix.) (RJ)
sl@0	3342
sl@0	3343	9/18/97 (bug fix) Fixed bug -dictionary option of lsort that could
sl@0	3344	cause the compare function to run off the end of an array if the
sl@0	3345	number only contained 0's. (Thanks to Greg Couch for the report.) (RJ)
sl@0	3346
sl@0	3347	9/18/97 (bug fix) TclFinalizeEnvironment was not cleaning up
sl@0	3348	properly. (DL, JI)
sl@0	3349
sl@0	3350	9/18/97 (bug fix) Fixed long-standing bug where an "array get" command
sl@0	3351	did not trigger traces on the array or its elements. (BL)
sl@0	3352
sl@0	3353	9/18/97 (bug fixes) Fixed compilation-related bugs:
sl@0	3354	- Fixed errorInfo traceback information for toplevel coomands that
sl@0	3355	contain nested commands.
sl@0	3356	- In the expr command, && and \|\| now accept boolean operands as well
sl@0	3357	as numeric ones. (BL)
sl@0	3358
sl@0	3359	9/22/97 (bug fix) Fixed bug that prevented translation modes from being
sl@0	3360	set independently for input and output on sockets if input was "auto". (JL)
sl@0	3361
sl@0	3362	9/24/97 (bug fix) Tcl_EvalFile(3) and thus source(n) now works fine on
sl@0	3363	files containing NUL chars. (DL)
sl@0	3364
sl@0	3365	9/26/97 (bug fix) Fixed use of uninitialized memory in the environ array
sl@0	3366	that later could cause random core dumps. Applies to all platforms. (JL)
sl@0	3367
sl@0	3368	9/26/97 (bug fix) Fixed use of uninitialized memory in socket address data
sl@0	3369	structure under some circumstances. This could cause random core dumps.
sl@0	3370	This applies only to Unix. (JL)
sl@0	3371
sl@0	3372	9/26/97 (bug fix) Opening files on PC-NFS volumes would cause a hang
sl@0	3373	until the system timed after the file was closed. (SS)
sl@0	3374
sl@0	3375	10/6/97 (bug fix) The join(n) command, though objectified, was loosing
sl@0	3376	NULs in the joinString and in list elements after the 2nd one.
sl@0	3377	Now you can "join $list \0" for instance. (DL)
sl@0	3378
sl@0	3379	10/9/97 (bug fix) Under windows, if env(TMP) or env(TEMP) referred to a
sl@0	3380	non-existent directory, exec would fail when trying to create its temporary
sl@0	3381	files. (CCS)
sl@0	3382
sl@0	3383	10/9/97 (bug fix) Under mac and windows, "info hostname" would crash if
sl@0	3384	sockets were installed but the hostname could not be determined anyhow.
sl@0	3385	Tcl_GetHostName() was returning NULL when it should have been returning
sl@0	3386	an empty string. (CCS)
sl@0	3387
sl@0	3388	10/10/97 (bug fix) "file attribute /" returned error on windows. (CCS)
sl@0	3389
sl@0	3390	10/10/97 (bug fix) Fixed the auto_load procedure to handle procedures
sl@0	3391	defined in namespaces better. Also fixed pgk_mkIndex so it sees procedures
sl@0	3392	defined in nested namespaces. Index entries are still only made for
sl@0	3393	exported procedures. (BW)
sl@0	3394
sl@0	3395	10/13/97 (bug fix) On unix, for files with unknown group or owner
sl@0	3396	attributes, querying the "file attributes" would return an error rather than
sl@0	3397	returning the group's or owner's id number, although tha command accepts
sl@0	3398	numbers when setting the file's group or owner. (CCS)
sl@0	3399
sl@0	3400	10/22/97 (bug fix) "fcopy" did not eval the callback script at the
sl@0	3401	global scope. (SS)
sl@0	3402
sl@0	3403	10/22/97 (bug fix) Fixed the signature of the CopyDone callback used in
sl@0	3404	the http package(s) so they can handle error cases properly. (BW)
sl@0	3405
sl@0	3406	10/28/97 (bug fixes) Fixed a problem where lappend would free the Tcl object
sl@0	3407	in a variable if a Tcl_ObjSetVar2 failed because of an error calling a trace
sl@0	3408	on the variable. (BL)
sl@0	3409
sl@0	3410	10/28/97 (bug fix) Changed binary scan to properly handle sign
sl@0	3411	extension of integers on 64-bit or larger machines. (SS)
sl@0	3412
sl@0	3413	11/3/97 (bug fixes) Fixed several bugs:
sl@0	3414	- expressions such as "expr ($x)" must be compiled out-of-line
sl@0	3415	(call the expr command procedure at runtime) to ensure the correct
sl@0	3416	behavior when "$x" is an expression such as "5+10".
sl@0	3417	- "array set a {}" now creates a new array var with an empty array
sl@0	3418	value if the var didn't already exist.
sl@0	3419	- "lreplace $foo end end" no longer returns an error (just an empty
sl@0	3420	list) if foo is empty.
sl@0	3421	- upvar will no longer create a variable in a namespace that refers
sl@0	3422	to a variable in a procedure.
sl@0	3423	- deleting a command trace within a command trace callback would
sl@0	3424	make the code that calls traces to reference freed memory.
sl@0	3425	- significantly sped up "string first" and "string last" (fix from
sl@0	3426	darrel@gemstone.com).
sl@0	3427	- seg fault in Tcl_NewStringObj() when a NULL is passed as the byte
sl@0	3428	pointer argument and Tcl is compiled with -DTCL_MEM_DEBUG.
sl@0	3429	- documentation and error msg fixes. (BL)
sl@0	3430
sl@0	3431	11/3/97 (bug fix) Fixed a number of I/O bugs related to word sizes on
sl@0	3432	64-bit machines. (SS)
sl@0	3433
sl@0	3434	11/6/97 (bug fix) The exit code of the first process created by Tcl
sl@0	3435	on Windows was not properly reported due to an initialization
sl@0	3436	problem. (SS)
sl@0	3437
sl@0	3438	----------------- Released 8.0p1, 11/7/97 -----------------------
sl@0	3439
sl@0	3440	11/19/97 (bug fix) Fixed bug in linsert where it sometimes accidently
sl@0	3441	cleared out a shared argument list object. (BL).
sl@0	3442
sl@0	3443	11/19/97 (bug fix) Autoloading in namespaces was not working properly.
sl@0	3444	auto_mkindex is still not really namespace aware but most common
sl@0	3445	cases should now be handled properly (see init.test). (BW, DL)
sl@0	3446
sl@0	3447	11/20/97 (enhancement) Made the changes required by the new Apple
sl@0	3448	Universal Headers V.3.0, so that Tcl will compile with CW Pro 2.
sl@0	3449
sl@0	3450	11/24/97 (bug fix) Fixed tests in clock test suite that needed the
sl@0	3451	-gmt flag set. Thanks to Jan Nijtmans for reporting the problem. (RJ)
sl@0	3452
sl@0	3453	----------------- Released 8.0p2, 11/25/97 -----------------------
sl@0	3454
sl@0	3455	12/3/97 (bug fix/optimization) Removed uneeded and potentially dangerous
sl@0	3456	instances of double evaluations if "if" and "expr" statements from
sl@0	3457	the library files. It is recommended that unless you need a double
sl@0	3458	evaluation you always use "expr {...}" instead of "expr ..." and
sl@0	3459	"if {...} ..." instead of "if ... ...". It will also be faster
sl@0	3460	thanks to the byte compiler. (DL)
sl@0	3461
sl@0	3462	---- Shipped as part of the plugin2.0b5 as 8.0p2Plugin1, Dec 8th 97 ----
sl@0	3463
sl@0	3464	12/8/97 (bug fix) Need to protect the newly accepted channel in an
sl@0	3465	accept callback on a socket, otherwise the callback may close it and
sl@0	3466	cause an error, which would cause the C code to attempt to close the
sl@0	3467	now deleted channel. Bumping the refcount assures that the channel sticks
sl@0	3468	around to be really closed in this case. (JL)
sl@0	3469
sl@0	3470	12/8/97 (bug fix) Need to protect the channel in a fileevent so that it
sl@0	3471	is not deleted before the fileevent handler returns. (CS, JL)
sl@0	3472
sl@0	3473	12/18/97 (bug fix) In the opt argument parsing package: if the description
sl@0	3474	had only flags, the "too many arguments" case was not detected. The default
sl@0	3475	value was not used for the special "args" ending argument. (DL)
sl@0	3476
sl@0	3477	1/15/98 (improvement) Moved common part of initScript in common file.
sl@0	3478	Moved windows specific initialization to init.tcl so you can initialize
sl@0	3479	Tcl in windows without having to call Tcl_Init which is now only
sl@0	3480	searching for init.tcl {back ported from 8.1}. (DL)
sl@0	3481
sl@0	3482	---- Shipped as part of the plugin as 8.0p2Plugin2, Jan 15th 98 ----
sl@0	3483
sl@0	3484	5/27/98 (bug fix) Windows socket driver did not notice new data arriving
sl@0	3485	on nonblocking sockets until the event loop was entered. (SS)
sl@0	3486
sl@0	3487	5/27/98 (bug fix) Windows socket driver used FIONREAD, which is not
sl@0	3488	supported correctly by WinSock. (SS)
sl@0	3489
sl@0	3490	6/9/98 (bug fix) Generic channel code failed to report readable file
sl@0	3491	events on buffered data that was left behind by a gets or read that
sl@0	3492	did not consume all available data. (SS)
sl@0	3493
sl@0	3494	6/18/98 (bug fix) Compilation of loop expressions was too aggressive
sl@0	3495	and incorrectly inlined non-literal expressions. (SS)
sl@0	3496
sl@0	3497	6/18/98 (bug fix) "info var" and "info locals" incorrectly reported
sl@0	3498	the existence of compiler temporary variables. (SS)
sl@0	3499
sl@0	3500	6/18/98 (bug fix) Dictionary sorting used signed character
sl@0	3501	comparisons. (SS)
sl@0	3502
sl@0	3503	6/18/98 (bug fix) Compile procs corrupted the exception stack in some
sl@0	3504	cases. (SS)
sl@0	3505
sl@0	3506	6/18/98 (bug fix) Array set had erratic behavior when initializing a
sl@0	3507	variable from an empty value list. (SS)
sl@0	3508
sl@0	3509	6/18/98 (bug fix) The Windows registry package had a bad bounds check
sl@0	3510	that could lead to a crash. (SS)
sl@0	3511
sl@0	3512	6/18/98 (bug fix) The foreach compile proc did not correctly handle
sl@0	3513	non-local variable references. (SS)
sl@0	3514
sl@0	3515	6/25/98 (new features) Added name resolution hooks to support [incr Tcl].
sl@0	3516	There are new internal Tcl_Resolver APIs to add, query and remove the hooks.
sl@0	3517	With this changes it should be possible to dynamically load [incr Tcl]
sl@0	3518	as an extension. (MM)
sl@0	3519
sl@0	3520	7/1/97 (bug fix) The commands "info args, body, default, procs" did
sl@0	3521	not correctly handle imported procedures. (RJ)
sl@0	3522
sl@0	3523	7/6/98 (improvement) pkg_mkIndex now implements the "package require"
sl@0	3524	command. This makes it possible to create index files for packages
sl@0	3525	that require another package and then execute code from that package in
sl@0	3526	their file. Previously, this would throw an error because the required
sl@0	3527	package had not been loaded. The -nopkgrequied flag is provided to
sl@0	3528	revert back to the old functionality. (EMS)
sl@0	3529
sl@0	3530	7/6/98 (improvement) back-ported the -direct flag from 8.1 into
sl@0	3531	pkg_mkIndex. This results in pkgIndex.tcl files that contain direct
sl@0	3532	source or load commands instead of tclPkgSetup commands. (EMS)
sl@0	3533
sl@0	3534	7/6/98 (improvement) made changes to the AuxData items structures to support
sl@0	3535	storage of compiled scripts on disk. Also some related minor changes in
sl@0	3536	the compilation and execution engine. (EMS)
sl@0	3537
sl@0	3538	6/4/98 (enhancement) Added new internal routines to support inserting
sl@0	3539	and deleting from the stat, access, and open-file-channel mechanisms.
sl@0	3540	TclAccessInsertProc, TclStatInsertProc, & TclOpenFileChannelInsertProc
sl@0	3541	insert pointers to such routines; TclAccessDeleteProc, TclStatDeleteProc,
sl@0	3542	& TclOpenFileChannelDeleteProc delete pointers to such routines. See
sl@0	3543	the file generic/tclIOUtils.c for more details. (SKS)
sl@0	3544
sl@0	3545	7/1/98 (enhancement) Added a new internal C variable
sl@0	3546	tclPreInitScript. This is a pointer to a string that may hold an
sl@0	3547	initialization script; If this pointer is non-NULL it is evaluated in
sl@0	3548	Tcl_Init() prior to the built-in initialization script defined in the
sl@0	3549	file generic/tclInitScript.h. (SKS)
sl@0	3550
sl@0	3551	7/6/98 (bug fix) Removed dead code in PlatformInitExitHandler so that
sl@0	3552	the TCL_LIBRARY value can be safely patched in binaries. (BW)
sl@0	3553
sl@0	3554	7/24/98 (enhancement) Incorporated a new version of auto_mkindex that
sl@0	3555	can support the [incr Tcl] class structures. This version will index
sl@0	3556	all procedures in a source file, not just those where "proc" starts
sl@0	3557	at the beginning of the line. If you want the old behavior, use the
sl@0	3558	auto_mkindex_old procedure. (MM)
sl@0	3559
sl@0	3560	7/24/98 (feature change) Changed the Windows registry key to be
sl@0	3561	HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, and to store the path
sl@0	3562	in the default value instead of "Root". Also, this key can be
sl@0	3563	specified at compile time in case Tcl is being used in a different
sl@0	3564	context where it needs an alternate library path from the standard Tcl
sl@0	3565	installation. (SS)
sl@0	3566
sl@0	3567	7/24/98 (feature change) Changed the search order for init.tcl. The
sl@0	3568	tcl_library variable can now be set before calling Tcl_Init to avoid
sl@0	3569	doing any searches. If it isn't set, then Tcl checks
sl@0	3570	env(TCL_LIBRARY), the static value set at compile time, an install
sl@0	3571	directory relative to the executable, a source directory relative to
sl@0	3572	the executable, and a tcl directory relative to the source heirarchy
sl@0	3573	containing the executable. See the comment at the top of
sl@0	3574	generic/tclInitScript.h for more details. (SS)
sl@0	3575
sl@0	3576	7/27/98 (config change) Changed the use of the DBGX flag in configure.in
sl@0	3577	and the makefile to be TCL_DBGX. Users of tclConfig.sh may need to pass
sl@0	3578	this through their configure files with AC_SUBST. (BW)
sl@0	3579
sl@0	3580	729/98 (bug fix) Changed [info body] to return a copy of the body of a
sl@0	3581	compiled procedure instead of the body itself, to avoid invalidation
sl@0	3582	of the internal rep and loss of the byte-codes. (EMS)
sl@0	3583
sl@0	3584	8/5/98 (bug fix) The platform init code could walk off the end of a
sl@0	3585	buffer when reading the PkgPath registry value on Windows. (SS)
sl@0	3586
sl@0	3587	8/5/98 (Windows makefile change) Introduced a set of macros to deal with
sl@0	3588	exporting symbols when compiling DLLS on Windows. See win/README for
sl@0	3589	details. (EMS)
sl@0	3590
sl@0	3591	8/5/98 (addendum) Added a second Windows registry key under
sl@0	3592	HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, named "pkgPath".
sl@0	3593	This is a multi-string value used to initialize the tcl_pkgPath
sl@0	3594	variable. This is required if extension DLLs are in architecture specific
sl@0	3595	subdirectories. (SS)
sl@0	3596
sl@0	3597	8/6/98 (new feature) Added tcl_findLibrary to init.tcl for use by
sl@0	3598	extensions, including Tk. This searches in a canonical way for
sl@0	3599	an extensions library directory and initialization file. (BW)
sl@0	3600
sl@0	3601	8/10/98 (bug fix) Imported commands used to get lost if the target
sl@0	3602	of the import was redefined. Tcl_CreateCommand and Tcl_CreateObjCommand
sl@0	3603	were updated to restore import links. (Note that if you rename a command,
sl@0	3604	the import links move to the new name, and if you delete a command then
sl@0	3605	the import links get lost. These semantics have not changed.) (MC)
sl@0	3606
sl@0	3607	-------- Released 8.0.3 to the Tcl Consortium CD-ROM project, 8/10/98 ------
sl@0	3608
sl@0	3609	9/3/98 (bug fix) Tcl_Realloc was failing under Windows because the
sl@0	3610	GlobalReAlloc API was not correctly re-allocating blocks that were
sl@0	3611	32k+. The fix was to use newer Win32 APIs (HeapAlloc, HeapFree, and
sl@0	3612	HeapReAlloc.) (BS)
sl@0	3613
sl@0	3614	10/5/98 (bug fix) Fixed bug in pkg_mkIndex that caused some files that do
sl@0	3615	a "package require" of packages in the Tcl libraries to give a warning like
sl@0	3616	warning: "xx.tcl" provides more than one package ({xx 2.0} {yy 0.3})
sl@0	3617	and generate a broken pkgIndex.tcl file. (EMS)
sl@0	3618
sl@0	3619	10/5/98 (bug fix) Pkg_mkIndex was not doing a case-insensitive comparison
sl@0	3620	of extensions to determine whether to load or source a file. Thus, under
sl@0	3621	Windows, MYDLLNAME.DLL was sourced, and mydllname.dll loaded. (EMS)
sl@0	3622
sl@0	3623	10/5/98 (new feature) Created a new Tcl_Obj type, "procbody". This object's
sl@0	3624	internal representation holds a pointer to a Proc structure. Extended
sl@0	3625	TclCreateProc to take both strings and "procbody". (EMS)
sl@0	3626
sl@0	3627	10/13/98 (bug fix) The "info complete" command can now handle strings
sl@0	3628	with NULLs embedded. Thanks to colin@field.medicine.adelaide.edu.au
sl@0	3629	for providing this fix. (RJ)
sl@0	3630
sl@0	3631	10/13/98 (bug fix) The "lsort -dictionary" command did not properly
sl@0	3632	handle some numbers starting with 0. Thanks to Richard Hipp
sl@0	3633	<drh@acm.org> for submitting the fix to Scriptics. (RJ)
sl@0	3634
sl@0	3635	10/13/98 (bug fix) The function Tcl_SetListObj was creating an invalid
sl@0	3636	Tcl_Obj if the list had zero elements (despite what the comments said
sl@0	3637	it would do). Thanks to Sebastian Wangnick for reporting the
sl@0	3638	problem. (RJ)
sl@0	3639
sl@0	3640	10/20/98 (new feature) Added tcl_platform(debug) element to the
sl@0	3641	tcl_platform array on Windows platform. The existence of the debug
sl@0	3642	element of the tcl_platform array indicates that the particular Tcl
sl@0	3643	shell has been compiled with debug information. Using
sl@0	3644	"info exists tcl_platform(debug)" a Tcl script can direct the
sl@0	3645	interpreter to load debug versions of DLLs with the load
sl@0	3646	command. (SKS)
sl@0	3647
sl@0	3648	10/20/98 (feature change) The Makefile and configure scripts have been
sl@0	3649	changed for IRIX to build n32 binaries instead of the old 32 abi
sl@0	3650	format. If you have extensions built with the o32 abi's you will need
sl@0	3651	to update them to n32 for them to work with Tcl. (RJ)
sl@0	3652	* POTENTIAL INCOMPATIBILITY *
sl@0	3653
sl@0	3654	10/23/98 (bug fix) tcl_findLibrary had a stray ] in one of the
sl@0	3655	pathnames it searched for the initialization script. tclInitScript.h
sl@0	3656	was incorrectly adding the parent of tcl_library to tcl_pkgPath. This
sl@0	3657	logic was moved into init.tcl, and the initialization of auto_path was
sl@0	3658	documented. Thanks to Donald Porter and Tom Silva for related
sl@0	3659	patches. (BW)
sl@0	3660
sl@0	3661	10/29/98 (bug fix) Fixed Tcl_NotifyChannel to use Tcl_Preserve instead
sl@0	3662	of Tcl_RegisterChannel so that 1) unregistered channels do not get
sl@0	3663	closed after their first fileevent, and 2) errors that occur during
sl@0	3664	close in a fileevent script are actually reflected by the close
sl@0	3665	command. (BW)
sl@0	3666
sl@0	3667	10/30/98 (bug fix) Overhaul of pkg_mkIndex to deal with transitive
sl@0	3668	package requires and packages split among scripts and binary files.
sl@0	3669	Also fixed ommision of global for errorInfo in tcl_findLibrary. (BW)
sl@0	3670
sl@0	3671	11/08/98 (bug fix) Fixed the resource command to always detect
sl@0	3672	the case where a file is opened a second time with the same
sl@0	3673	permissions. IM claims that this will always cause the same
sl@0	3674	FileRef to be returned, but in MacOS 8.1+, this is no longer the case,
sl@0	3675	so we have to test for this explicitly. (JI)
sl@0	3676
sl@0	3677	11/10/98 (feature change) When compiling with Metrowerk's MSL, use the
sl@0	3678	exit function from MSL rather than ExitToShell. This allows MSL to
sl@0	3679	clean up its temporary files. Thanks to Vince Darley for this
sl@0	3680	improvement. (JI)
sl@0	3681
sl@0	3682	----------------- Released 8.0.4, 11/19/98 -------------------------
sl@0	3683
sl@0	3684	11/20/98 (bug fix) Handle possible NULL return in TclGetStdFiles. (RJ)
sl@0	3685
sl@0	3686	11/20/98 (bug fix) The dltests would not build on SGI. They reported
sl@0	3687	that you could not mix n32 with 032 binaries. The configure script
sl@0	3688	has been modified to get the EXTRA_CFLAGS from the tcl configure
sl@0	3689	script. [Bug id: 840] (RJ)
sl@0	3690
sl@0	3691	12/3/98 (bug fix) Windows NT creates sockets so they are inheritable
sl@0	3692	by default. Fixed socket code so it turns off this bit right after
sl@0	3693	creation so sockets aren't kept open by exec'ed processes. [Bug: 892]
sl@0	3694	Thanks to Kevin Kenny for this fix. (SS)
sl@0	3695
sl@0	3696	1/11/98 (bug fix) On HP, "info sharedlibextension" was returning
sl@0	3697	empty string on static apps. It now always returns ".sl". (RJ)
sl@0	3698
sl@0	3699	1/28/99 (configure change) Now support -pipe option on gcc. (RJ)
sl@0	3700
sl@0	3701	2/2/99 (bug fix) Fixed initialization problem on Windows where no
sl@0	3702	searching for init.tcl would be performed if the registry keys were
sl@0	3703	missing. (stanton)
sl@0	3704
sl@0	3705	2/2/99 (bug fix) Added support for HKEY_PERFORMANCE_DATA and
sl@0	3706	HKEY_DYN_DATA keys in the "registry" command. (stanton)
sl@0	3707
sl@0	3708	2/2/99 (bug fix) ENOTSUP and EOPNOTSUPP clashed on some Linux
sl@0	3709	variants. (stanton)
sl@0	3710
sl@0	3711	2/2/99 (enhancement) The "open" command has been changed to use the
sl@0	3712	object interfaces. (stanton)
sl@0	3713
sl@0	3714	2/2/99 (bug fix) In some cases Tcl would crash due to an overflow of
sl@0	3715	the exception stack resulting from a missing byte code in some
sl@0	3716	expressions. (stanton)
sl@0	3717
sl@0	3718	2/2/99 (bug fix) Changed configure so Linux and IRIX shared libraries
sl@0	3719	are linked with the system libraries. (stanton)
sl@0	3720
sl@0	3721	2/2/99 (bug fix) Added support for BSDI 4.x (BSD/OS-4*) to the
sl@0	3722	configure script. (stanton)
sl@0	3723
sl@0	3724	2/2/99 (bug fix) Fixed bug where upvar could resurrect a namespace
sl@0	3725	variable after the namespace had been deleted. (stanton)
sl@0	3726
sl@0	3727	2/2/99 (bug fix) In some cases when creating variables, the
sl@0	3728	interpreter result was being modified even if the TCL_LEAVE_ERR_MSG
sl@0	3729	flag was set. (stanton)
sl@0	3730
sl@0	3731	2/2/99 (bug fix & new feature) Changed the socket drivers to properly
sl@0	3732	handle failures during an async socket connection. Added a new
sl@0	3733	fconfigure option "-error" to retrieve the failure message. See the
sl@0	3734	socket.n manual entry for details. (stanton)
sl@0	3735
sl@0	3736	2/2/99 (bug fix) Deleting a renamed interp alias could result in a
sl@0	3737	panic. (stanton)
sl@0	3738
sl@0	3739	2/2/99 (feature change/bug fix) Changed the behavior of "file
sl@0	3740	extension" so that it splits at the last period. Now the extension of
sl@0	3741	a file like "foo..o" is ".o" instead of "..o" as in previous versions.

sl@0	3743
sl@0	3744	----------------- Released 8.0.5, 3/9/99 -------------------------
sl@0	3745
sl@0	3746	======== Changes for 8.0 go above this line ========
sl@0	3747	======== Changes for 8.1 go below this line ========
sl@0	3748
sl@0	3749	6/18/97 (new feature) Tcl now supports international character sets:
sl@0	3750	- All C APIs now accept UTF-8 strings instead of iso8859-1 strings,
sl@0	3751	wherever you see "char *", unless explicitly noted otherwise.
sl@0	3752	- All Tcl strings represented in UTF-8, which is a convenient
sl@0	3753	multi-byte encoding of Unicode. Variable names, procedure names,
sl@0	3754	and all other values in Tcl may include arbitrary Unicode characters.
sl@0	3755	For example, the Tcl command "string length" returns how many
sl@0	3756	Unicode characters are in the argument string.
sl@0	3757	- For Java compatibility, embedded null bytes in C strings are
sl@0	3758	represented as \xC080 in UTF-8 strings, but the null byte at the end
sl@0	3759	of a UTF-8 string remains \0. Thus Tcl strings once again do not
sl@0	3760	contain null bytes, except for termination bytes.
sl@0	3761	- For Java compatibility, "\uXXXX" is used in Tcl to enter a Unicode
sl@0	3762	character. "\u0000" through "\uffff" are acceptable Unicode
sl@0	3763	characters.
sl@0	3764	- "\xXX" is used to enter a small Unicode character (between 0 and 255)
sl@0	3765	in Tcl.
sl@0	3766	- Tcl automatically translates between UTF-8 and the normal encoding for
sl@0	3767	the platform during interactions with the system.
sl@0	3768	- The fconfigure command now supports a -encoding option for specifying
sl@0	3769	the encoding of an open file or socket. Tcl will automatically
sl@0	3770	translate between the specified encoding and UTF-8 during I/O.
sl@0	3771	See the directory library/encoding to find out what encodings are
sl@0	3772	supported (eventually there will be an "encoding" command that
sl@0	3773	makes this information more accessible).
sl@0	3774	- There are several new C APIs that support UTF-8 and various encodings.
sl@0	3775	See Utf.3 for procedures that translate between Unicode and UTF-8
sl@0	3776	and manipulate UTF-8 strings. See Encoding.3 for procedures that
sl@0	3777	create new encodings and translate between encodings. See
sl@0	3778	ToUpper.3 for procedures that perform case conversions on UTF-8
sl@0	3779	strings.
sl@0	3780
sl@0	3781	9/18/97 (enhancement) Literal objects are now shared by the ByteCode
sl@0	3782	structures created when compiled different scripts. This saves up to 45%
sl@0	3783	of the total memory needed for all literals. (BL)
sl@0	3784
sl@0	3785	9/24/97 (bug fixes) Fixed Tcl_ParseCommand parsing of backslash-newline
sl@0	3786	sequences at start of command words. Suppressed Tcl_EvalDirect error logging
sl@0	3787	if non-TCL_OK result wasn't an error. (BL)
sl@0	3788
sl@0	3789	10/17/97 (feature enhancement) "~username" now refers to the users' home
sl@0	3790	directory on Windows (previously always returned failure). (CCS)
sl@0	3791
sl@0	3792	10/20/97 (implementation change) The Tcl parser has been completely rewritten
sl@0	3793	to make it more modular. It can now be used to parse a script without actually
sl@0	3794	executing it. The APIs for the new parser are not correctly exported, but
sl@0	3795	they will eventually be exported and augmented with Tcl commands so that
sl@0	3796	Tcl scripts can parse other Tcl scripts. (JO)
sl@0	3797
sl@0	3798	10/21/97 (API change) Added "flags" argument to Tcl_EvalObj, removed
sl@0	3799	Tcl_GlobalEvalObj procedure. Added new procedures Tcl_Eval2 and
sl@0	3800	Tcl_EvalObjv. (JO)
sl@0	3801	* POTENTIAL INCOMPATIBILITY *
sl@0	3802
sl@0	3803	10/22/97 (API change) Renamed Tcl_ObjSetVar2 and Tcl_ObjGetVar2 to
sl@0	3804	Tcl_SetObjVar2 and Tcl_GetObjVar2 (for consistency with other C APIs)
sl@0	3805	and changed the name arguments to be strings instead of objects. (JO)
sl@0	3806	* POTENTIAL INCOMPATIBILITY *
sl@0	3807
sl@0	3808	10/27/97 (enhancement) Bytecode compiler rewritten to use the new Tcl
sl@0	3809	parser. (BL)
sl@0	3810
sl@0	3811	11/3/97 (New routines) Added Tcl_AppendObjToObj, which appends the
sl@0	3812	string rep of one Tcl_Obj to another. Added Tcl_GetIndexFromObjStruct,
sl@0	3813	which is similar to Tcl_GetIndexFromObj, except that you can give an
sl@0	3814	offset between strings. This allows Tcl_GetIndexFromObjStruct to be
sl@0	3815	called with a table of records which have strings in them. (SRP)
sl@0	3816
sl@0	3817	12/4/97 (enhancement) New Tcl expression parser added. Added new procedure
sl@0	3818	Tcl_ParseExpr and new token types TCL_TOKEN_SUB_EXPR and
sl@0	3819	TCL_TOKEN_OPERATOR. Expression compiler is reimplemented to use this
sl@0	3820	parser. (BL)
sl@0	3821
sl@0	3822	12/9/97 (bug fix) Tcl_EvalObj() increments/decrements the refcount of the
sl@0	3823	script object to prevent the object from deleting itself while in the
sl@0	3824	middle of being evaluated. (CCS)
sl@0	3825
sl@0	3826	12/9/97 (bug fix) Memory leak in Tcl_GetsObjCmd(). (CCS)
sl@0	3827
sl@0	3828	12/11/97 (bug fix) Environment array leaked memory when compiled with
sl@0	3829	Visual C++. (SS)
sl@0	3830
sl@0	3831	12/11/97 (bug fix) File events and non-blocking I/O did not work on
sl@0	3832	pipes under Windows. Changed to use threads to achieve non-blocking
sl@0	3833	behavior. (SS)
sl@0	3834
sl@0	3835	12/18/97 (bug fixes) Fixed segfault in "namespace import"; importing a
sl@0	3836	procedure that causes a cycle now returns an error. Modified "info procs",
sl@0	3837	"info args", "info body", and "info default" to return information about
sl@0	3838	imported procedures as well as procedures defined in a namespace. (BL)
sl@0	3839
sl@0	3840	12/19/97 (enhancement) Added new Tcl_GetString() procedure that can be used
sl@0	3841	in place of Tcl_GetStringFromObj() if the string representation's length
sl@0	3842	isn't needed. (BL)
sl@0	3843
sl@0	3844	12/18/97 (bug fix) In the opt argument parsing package: if the description
sl@0	3845	had only flags, the "too many arguments" case was not detected. The default
sl@0	3846	value was not used for the special "args" ending argument. (DL)
sl@0	3847
sl@0	3848	1/7/98 (clean up) Moved everything not absolutly necessary out of init.tcl
sl@0	3849	procs now in auto.tcl and package.tcl can be autoloaded if needed. (DL)
sl@0	3850
sl@0	3851	1/7/98 (enhancement) tcltest made at install time will search for it's
sl@0	3852	init.tcl where it is, even when using virtual path compilation. (DL)
sl@0	3853
sl@0	3854	1/8/98 (os bug workaround) when needed, using a replacement for memcmp so
sl@0	3855	string compare "char with high bit set" "char w/o high bit set" returns
sl@0	3856	the expected value on all platforms. (DL)
sl@0	3857
sl@0	3858	1/8/98 (unix portability/configure) building from .../unix/targetName/
sl@0	3859	subdirectories and simply using "../configure" should now work fine. (DL)
sl@0	3860
sl@0	3861	1/14/98 (enhancement) Added new regular expression package that
sl@0	3862	supports AREs, EREs, and BREs. The new package includes new escape
sl@0	3863	characters, meta-syntax, and character classes inside brackets.
sl@0	3864	Regexps involving backslashes may behave differently. (MH)
sl@0	3865	* POTENTIAL INCOMPATIBILITY *
sl@0	3866
sl@0	3867	1/16/98 (os workaround) Under windows, "file volume" was causing chatter
sl@0	3868	and/or several seconds of hanging when querying empty floppy drives.
sl@0	3869	Changed implementation to call an empirically-derived function that doesn't
sl@0	3870	cause this. (CCS)
sl@0	3871
sl@0	3872	1/16/98 (enhancement) Converted regular expressions to a Tcl_Obj type so
sl@0	3873	their compiled form gets cached automatically. Reduced NSUBEXP from 100
sl@0	3874	to 20. (BW)
sl@0	3875
sl@0	3876	1/16/98 (documentation) Change unclear documentation and comments for
sl@0	3877	functions like Tcl_TranslateFileName() and Tcl_ExternalToUtfDString(). Now
sl@0	3878	it explicitly says they take an uninitialized or free DString. A DString
sl@0	3879	that is "empty" or "not holding anything" could have been interpreted as one
sl@0	3880	currently with a zero length, but with a large dynamically allocated buffer.
sl@0	3881	(CCS)
sl@0	3882
sl@0	3883	----------------- Released 8.1a1, 1/22/98 -----------------------
sl@0	3884
sl@0	3885	1/28/98 (new feature) Added a "-direct" optional flag to pkg_mkIndex
sl@0	3886	to generate direct loading package indexes (such those you need
sl@0	3887	if you use namespaces and plan on using namespace import just after
sl@0	3888	package require). pkg_mkIndex still has limitations regarding
sl@0	3889	package dependencies but errors are now ignored and with -direct, correct
sl@0	3890	package indexes can be generated even if there are dependencies as long
sl@0	3891	as the "package provide" are done early enough in the files. (DL)
sl@0	3892
sl@0	3893	1/28/98 (enhancement) Performance tuning of regexp and regsub. (CCS)
sl@0	3894
sl@0	3895	1/28/98 (bug fix) regexp and regsub with "-indices" returned the byte-offsets
sl@0	3896	of the characters in the UTF-8 representation, not the character offsets
sl@0	3897	themselves. (CCS)
sl@0	3898
sl@0	3899	1/28/98 (bug fix) "clock format 0 -format %Z -gmt 1" would return the local
sl@0	3900	timezone string instead of "GMT" on Solaris and Windows.
sl@0	3901
sl@0	3902	1/28/98 (bug fix) Restore tty settings when closing serial device on Unix.
sl@0	3903	This is good behavior when closing real serial devices, essential when
sl@0	3904	closing the pseudo-device /dev/tty because the user's terminal settings
sl@0	3905	would be left useless, in raw mode, when tcl quit. (CCS)
sl@0	3906
sl@0	3907	1/28/98 (bug fix) Tcl_OpenCommandChannel() was modifying the contents of the
sl@0	3908	argv array passed to it, causing problems for any caller that wanted to
sl@0	3909	continue to use the argv array after calling Tcl_OpenCommandChannel(). (CCS)
sl@0	3910
sl@0	3911	2/1/98 (bug fix) More bugs with %Z in format string argument to strftime():
sl@0	3912	1. Borland always returned empty string.
sl@0	3913	2. MSVC always returned the timezone string for the current time, not the
sl@0	3914	timezone string for the specified time.
sl@0	3915	3. With MSVC, "clock format 0 -format %Z -gmt 1" would return "GMT" the first
sl@0	3916	time it was called, but would return the current timezone string on all
sl@0	3917	subsequent calls. (CCS)
sl@0	3918
sl@0	3919	2/1/98 (bug fix) "file stat" was broken on Windows.
sl@0	3920	1. "file stat" of a root directory (local or network) or a relative path that
sl@0	3921	resolved to a root directory (c:. when in pwd was c:/) was returning error.
sl@0	3922	2. "file stat" on a regular file (S_IFREG), the st_mode was sign extended to
sl@0	3923	a negative int if the platform-dependant type "mode_t" was declared as a
sl@0	3924	short instead of an unsigned short.
sl@0	3925	3. "file stat" of a network directory, the st_dev was incorrectly reported
sl@0	3926	as the id of the last accessed local drive rather than the id of the
sl@0	3927	network drive. (CCS)
sl@0	3928
sl@0	3929	2/1/98 (bug fix) "file attributes" of a relative path that resolved to a
sl@0	3930	root directory was returning error. (CCS)
sl@0	3931
sl@0	3932	2/1/98 (bug fix) Change error message when "file attribute" could not
sl@0	3933	determine the attributes for a file. Previously it would return different
sl@0	3934	error messages on Unix vs. Windows vs. Mac. (CCS)
sl@0	3935
sl@0	3936	2/4/98 (bug fixes) Fixed several instances of bugs where the parser/compiler
sl@0	3937	would reach outside the range of allocated memory. Improved the array
sl@0	3938	lookup algorithm in set compilation. (DL)
sl@0	3939
sl@0	3940	2/5/98 (change) The TCL_PARSE_PART1 flag for Set/Get(Obj)Var2 C APIs is now
sl@0	3941	deprecated and ignored. The part1 is always parsed when the part2 argument
sl@0	3942	is NULL. This is to avoid a pattern of errors for extension writers converting
sl@0	3943	from string based Tcl_SetVar() to new Tcl_SetObjVar2() and who could easily
sl@0	3944	forget to provide the flag and thus get code working for normal variables
sl@0	3945	but not for array elements. The performance hit is minimal. A side effect
sl@0	3946	of that change is that is is no longer possible to create scalar variables
sl@0	3947	that can't be accessed by tcl scripts because of their invalid name
sl@0	3948	(ending with parenthesis). Likewise it is also parsed and checked to
sl@0	3949	ensure that you don't create array elements of array whose name is a valid
sl@0	3950	array element because they would not be accessible from scripts anyway.
sl@0	3951	Note: There is still duplicate array elements parsing code. (DL)
sl@0	3952	* POTENTIAL INCOMPATIBILITY *
sl@0	3953
sl@0	3954	2/11/98 (bug fix) Sharing objects between interps, such as by "interp
sl@0	3955	eval" or "send" could cause a crash later when dereferencing an interp
sl@0	3956	that had been deleted, given code such as:
sl@0	3957	set a {set x y}
sl@0	3958	interp create foo
sl@0	3959	interp eval foo $a
sl@0	3960	interp delete foo
sl@0	3961	unset a
sl@0	3962	Interp "foo" was gone, but "a" had a internal rep consisting of bytecodes
sl@0	3963	containing a dangling pointer to "foo". Unsetting "a" would attempt to
sl@0	3964	return resources back to "foo", causing a crash as random memory was
sl@0	3965	accessed. The lesson is that that if an object's internal rep depends on
sl@0	3966	an interp (or any other data structure) it must preserve that data in
sl@0	3967	some fashion. (CCS)
sl@0	3968
sl@0	3969	2/11/98 (enhancement) The "interp" command was returning inconsistent error
sl@0	3970	messages when the specified slave interp could not be found. (CCS)
sl@0	3971
sl@0	3972	2/11/98 (bug fix) Result codes like TCL_BREAK and TCL_CONTINUE were not
sl@0	3973	propagating through the master/slave interp boundaries, such as "interp
sl@0	3974	eval" and "interp alias". TCL_OK, TCL_ERROR, and non-standard codes like
sl@0	3975	teh integer 57 work. There is still a question as to whether TCL_RETURN
sl@0	3976	can/should propagate. (CCS)
sl@0	3977
sl@0	3978	2/11/98 (bug fix) TclCompileScript() was derefering memory 1 byte before
sl@0	3979	start of the string to compile, looking for ']'. (CCS,DL)
sl@0	3980
sl@0	3981	2/11/98 (bug fix) Tcl_Eval2() was derefering memory 1 byte before start
sl@0	3982	of the string to eval, looking for ']'. (CCS,DL)
sl@0	3983
sl@0	3984	2/11/98 (bug fix) Compiling "set a(b" was running off end of string. (CCS,DL)
sl@0	3985
sl@0	3986	2/11/98 (bug fix) Windows initialization code was dereferencing
sl@0	3987	uninitialized memory if TCL_LIBRARY environment didn't exist. (CCS)
sl@0	3988
sl@0	3989	2/11/98 (bug fix) Windows "registry" command was dereferencing
sl@0	3990	uninitialized memory when constructing the $errorCode for a failed
sl@0	3991	registry call. (CCS)
sl@0	3992
sl@0	3993	2/11/98 (enhancement) Eliminate the TCL_USE_TIMEZONE_VAR definition from
sl@0	3994	configure.in, because it was the same information as the already existing
sl@0	3995	HAVE_TM_ZONE definition. The lack of HAVE_TM_ZONE is used to work around a
sl@0	3996	Solaris and Windows bug where "clock format [clock sec] -format %Z -gmt 1"
sl@0	3997	produces the local timezone string instead of "GMT". (CCS)
sl@0	3998
sl@0	3999	2/11/98 (bug fix) Memleaks and dereferencing of uninitialized memory in
sl@0	4000	regexp if an error occurred while compiling a regular expression. (CCS).
sl@0	4001
sl@0	4002	2/18/98 (new feature) Added mutexes and thread local storage in order
sl@0	4003	to make Tcl thread safe. For testing purposes, there is a testthread
sl@0	4004	command that creates a new thread and an interpreter inside it. See
sl@0	4005	thread.test for examples, but this script-level interface is not fixed.
sl@0	4006	Each thread has its own notifier instance to manage its own events,
sl@0	4007	and threads can post messages to each other's message queue.
sl@0	4008	This uses pthreads on UNIX, and native thread support on other platforms.
sl@0	4009	You enable this by configuring with --enable-threads. Note that at
sl@0	4010	this time Tk is still not thread safe. Special thanks to
sl@0	4011	Richard Hipp: his earlier implementation inspired this work. (BW, SS, JI)
sl@0	4012
sl@0	4013	2/18/98 (hidden feature change) The way the env() array is shared among
sl@0	4014	interpreters changed. Updates to env used to trigger write traces in
sl@0	4015	other interpreters. This undocumented feature is no longer implemented.
sl@0	4016	Instead, variable tracing is used to keep the C-level environ array in sync
sl@0	4017	with the Tcl-level env array. This required adding TCL_TRACE_ARRAY support
sl@0	4018	to Tcl_TraceVar2 so that array names works properly. (BW)
sl@0	4019	* POTENTIAL INCOMPATIBILITY *
sl@0	4020
sl@0	4021	2/18/98 (enhancement) Conditional compilation for unix systems (e.g.,
sl@0	4022	IRIX, SCO) that use f_bsize instead of st_blksize to determine disk block
sl@0	4023	size. (CCS)
sl@0	4024
sl@0	4025	2/23/98 (bug fix) Fixed the emulation of polling selects in the threaded
sl@0	4026	version of the Unix notifier. The bug was showing up on a multiprocessor
sl@0	4027	as starvation of the notifier thread. (BW)
sl@0	4028
sl@0	4029	----------------- Released 8.1a2, Feb 23 1998 -----------------------
sl@0	4030
sl@0	4031	9/22/98 (bug fix) Changed the value of TCL_TRACE_ARRAY so it no longer
sl@0	4032	conflicts with the deprecated TCL_PARSE_PART1 flag. This should
sl@0	4033	improve portability of C code. (stanton)
sl@0	4034
sl@0	4035	10/6/98 (bug fix) The compile procedure for "if" incorrectly attempted
sl@0	4036	to match against the literal string "if", resulting in a stack
sl@0	4037	overflow when "::if" was compiled. It also would incorrectly accept
sl@0	4038	"if" instead of "elsif" in later clauses. (stanton)
sl@0	4039
sl@0	4040	10/15/98 (new feature) Added a "totitle" subcommand to the "string"
sl@0	4041	command to convert strings to capitalize the first character of a string
sl@0	4042	and lowercase all of the other characters. (stanton)
sl@0	4043
sl@0	4044	10/15/98 (bug fix) Changed regexp and string commands to properly
sl@0	4045	handle case folding according to the Unicode character
sl@0	4046	tables. (stanton)
sl@0	4047
sl@0	4048	10/21/98 (new feature) Added an "encoding" command to facilitate
sl@0	4049	translations of strings between different character encodings. See
sl@0	4050	the encoding.n manual entry for more details. (stanton)
sl@0	4051
sl@0	4052	11/3/98 (bug fix) The regular expression character classification
sl@0	4053	syntax now includes Unicode characters in the supported
sl@0	4054	classes. (stanton)
sl@0	4055
sl@0	4056	11/6/98 (bug fix) Variable traces were causing crashes when upvar
sl@0	4057	variables went out of scope. [Bug: 796] (stanton)
sl@0	4058
sl@0	4059	11/9/98 (bug fix) "format" now correctly handles multibyte characters
sl@0	4060	in %s format strings. (stanton)
sl@0	4061
sl@0	4062	11/10/98 (new feature) "regexp" now accepts three new switches
sl@0	4063	("-line", "-lineanchor", and "-linestop") that control how regular
sl@0	4064	expressions treat line breaks. See the regexp manual entry for more
sl@0	4065	details. (stanton)
sl@0	4066
sl@0	4067	11/17/98 (bug fix) "scan" now correctly handles Unicode
sl@0	4068	characters. (stanton)
sl@0	4069
sl@0	4070	11/17/98 (new feature) "scan" now supports XPG3 position specifiers
sl@0	4071	and the "%n" conversion character. See the "scan" manual entry for
sl@0	4072	more details. (stanton)
sl@0	4073
sl@0	4074	11/17/98 (bug fix) The Tcl memory allocator now returns 8-byte aligned
sl@0	4075	chunks of memory which improves performance on Windows and avoids
sl@0	4076	crashes on other platforms. [Bug: 834] (stanton)
sl@0	4077
sl@0	4078	11/23/98 (bug fix) Applied various regular expression performance bug
sl@0	4079	fixes supplied by Henry Spencer. (stanton)
sl@0	4080
sl@0	4081	11/30/98 (bug fix) Fixed various thread related race conditions. [Bug:
sl@0	4082	880 & 607] (stanton)
sl@0	4083
sl@0	4084	11/30/98 (bug fix) Fixed a number of memory overflow and leak
sl@0	4085	bugs. [Bug: 584] (stanton)
sl@0	4086
sl@0	4087	12/1/98 (new feaure) Added support for Korean encodings. (stanton)
sl@0	4088
sl@0	4089	12/1/98 (feature change) Changed the Tcl_EvalObjv interface to remove
sl@0	4090	the string and length arguments.
sl@0	4091	* POTENTIAL INCOMPATIBILITY with previous alpha releases *
sl@0	4092
sl@0	4093	12/2/98 (bug fix) Fixed various bugs related to line feed
sl@0	4094	translation. [Bug: 887] (stanton)
sl@0	4095
sl@0	4096	12/4/98 (new feature) Added a message catalog facility to help with
sl@0	4097	localizing Tcl scripts. Thanks to Mark Harrison for contributing the
sl@0	4098	initial implementation of the "msgcat" package. (stanton)
sl@0	4099
sl@0	4100	12/7/98 (bug fix) The memory allocator was failing to update the
sl@0	4101	block list for large memory blocks that were reallocated into a
sl@0	4102	different address. [Bug: 933] (stanton)
sl@0	4103
sl@0	4104	----------------- Released 8.1b1, Dec 10 1998 -----------------------
sl@0	4105
sl@0	4106	12/22/98 (performance improvement) Improved the -command option of the
sl@0	4107	lsort command to better use the object system for improved
sl@0	4108	performance (about 5x speed up). Thanks to Syd Polk for suppling the
sl@0	4109	patch. [RFE: 726] (rjohnson)
sl@0	4110
sl@0	4111	2/10/99 (bug fix) Restored the Tcl_ObjSetVar2/Tcl_ObjGetVar2
sl@0	4112	interfaces from 8.0 and renamed the Tcl_GetObjVar2/Tcl_SetObjVar2
sl@0	4113	interfaces to Tcl_GetVar2Ex and Tcl_SetVar2Ex. This should provide
sl@0	4114	better compatibility with 8.0. (stanton)
sl@0	4115	* POTENTIAL INCOMPATIBILITY with previous alpha/beta releases *
sl@0	4116
sl@0	4117	2/10/99 (bug fix) Made the eval interfaces compatible with 8.0 by
sl@0	4118	renaming Tcl_EvalObj to Tcl_EvalObjEx, renaming Tcl_Eval2 to
sl@0	4119	Tcl_EvalEx and restoring Tcl_EvalObj and Tcl_GlobalEvalObj interfaces
sl@0	4120	so they match Tcl 8.0. (stanton)
sl@0	4121	* POTENTIAL INCOMPATIBILITY with previous alpha/beta releases *
sl@0	4122
sl@0	4123	2/25/99 (bug fix/new feature) On Windows, the channel drivers for
sl@0	4124	consoles and serial ports now completely support file events. (redman)
sl@0	4125
sl@0	4126	3/5/99 (bug fix) Integrated patches to fix various configure problems
sl@0	4127	that affected HP-UX-11, 64-bit IRIX, Linux, and Solaris. (stanton)
sl@0	4128
sl@0	4129	3/9/99 (bug fix) Integrated various AIX related patches to improve
sl@0	4130	support for shared libraries. (stanton)
sl@0	4131
sl@0	4132	3/9/99 (new feature) Added tcl_platform(user) to provide a portable
sl@0	4133	way to get the name of the current user. (welch)
sl@0	4134
sl@0	4135	3/9/99 (new feature) Integrated the stub library mechanism contributed
sl@0	4136	by Jan Nijtmans, Paul Duffin, and Jean-Claude Wippler. This feature
sl@0	4137	should make it possible to write extensions that support multiple
sl@0	4138	versions of Tcl simultaneously. It also makes it possible to
sl@0	4139	dynamically load extensions into statically linked interpreters. This
sl@0	4140	patch includes the following changes:
sl@0	4141	- Added a Tcl_InitStubs() interface
sl@0	4142	- Added Tcl_PkgProvideEx, Tcl_PkgRequireEx, Tcl_PkgPresentEx,
sl@0	4143	and Tcl_PkgPresent.
sl@0	4144	- Added va_list versions of all VARARGS functions so they can be
sl@0	4145	invoked from wrapper functions.
sl@0	4146	See the manual for more information. (stanton)
sl@0	4147
sl@0	4148
sl@0	4149	3/10/99 (feature change) Replaced Tcl_AlertNotifier with
sl@0	4150	Tcl_ThreadAlert since the Tcl_AlertNotifier function relied on passing
sl@0	4151	internal data structures. (stanton)
sl@0	4152	* POTENTIAL INCOMPATIBILITY with previous alpha/beta releases *
sl@0	4153
sl@0	4154	3/10/99 (new feature) Added a Tcl_GetVersion API to make it easier to
sl@0	4155	check the Tcl version and patch level from C. (redman)
sl@0	4156
sl@0	4157	3/14/99 (feature change) Tried to unify the TclpInitLibrary path
sl@0	4158	routines to look in similar places from Windows to UNIX. The new
sl@0	4159	library search path is: TCL_LIBRARY, TCL_LIBRARY/../tcl8.1, relative
sl@0	4160	to DLL (Windows Only) relative to installed executable, relative to
sl@0	4161	develop executable, and relative to compiled-in in location (UNIX
sl@0	4162	Only.) This fix included:
sl@0	4163	- Defining a TclpFindExecutable
sl@0	4164	- Moving Tcl_FindExecutable to a common area in tclEncoding.c
sl@0	4165	- Modifying the TclpInitLibraryPath routines.
sl@0	4166	(surles)
sl@0	4167
sl@0	4168	3/14/99 (feature change) Added hooks for TclPro Wrapper to initialize
sl@0	4169	the location of the encoding files and libraries. This fix included:
sl@0	4170	- Adding the TclSetPerInitScript routine.
sl@0	4171	- Modifying the Tcl_Init routines to evaluate the non-NULL
sl@0	4172	pre-init script.
sl@0	4173	- Adding the Tcl_SetdefaultEncodingDir and Tcl_GetDefaultEncodingDir
sl@0	4174	routines.
sl@0	4175	- Modifying the TclpInitLibrary routines to append the default
sl@0	4176	encoding dir.
sl@0	4177	(surles)
sl@0	4178
sl@0	4179	3/14/99 (feature change) Test suite now uses "test" namespace to
sl@0	4180	define the test procedure and other auxiliary procedures as well as
sl@0	4181	global variables.
sl@0	4182	- Global array testConfige is now called ::test::testConfig.
sl@0	4183	- Global variable VERBOSE is now called ::test::verbose, and
sl@0	4184	::test::verbose no longer works with numerical values. We've
sl@0	4185	switched to a bitwise character string. You can set
sl@0	4186	::test::verbose by using the -verbose option on the Tcl command
sl@0	4187	line.
sl@0	4188	- Global variable TESTS is now called ::test::matchingTests, and
sl@0	4189	can be set on the Tcl command line via the -match option.
sl@0	4190	- There is now a ::test::skipTests variable (works similarly to
sl@0	4191	::test::matchTests) that can be set on the Tcl command line via
sl@0	4192	the -match option.
sl@0	4193	- The test suite can now be run in any working directory. When
sl@0	4194	you run "make test", the working directory is nolonger switched
sl@0	4195	to ../tests.

sl@0	4197	* POTENTIAL INCOMPATIBILITY *
sl@0	4198
sl@0	4199	--------------- Released 8.1b2, March 16, 1999 ----------------------
sl@0	4200
sl@0	4201	3/18/99 (bug fix) Fixed missing/incorrect characters in shift-jis table
sl@0	4202	(stanton)
sl@0	4203
sl@0	4204	3/18/99 (feature change) The glob command ignores the
sl@0	4205	FS_CASE_IS_PRESERVED bit on file systesm and always returns
sl@0	4206	exactly what it gets from the system. (stanton)
sl@0	4207	* POTENTIAL INCOMPATIBILITY *
sl@0	4208
sl@0	4209	3/19/99 (new feature) Added support for --enable-64bit. For now,
sl@0	4210	this is only supported on Solaris 7 64bit (SunOS 5.7) using the Sun
sl@0	4211	compiler. (redman)
sl@0	4212
sl@0	4213	3/23/99 (bug fix) Fixed fileevents and gets on Windows consoles and
sl@0	4214	serial devices so that non-blocking channels do not block on partial
sl@0	4215	input lines. (redman)
sl@0	4216
sl@0	4217	3/23/99 (bug fix) Added a new Tcl_ServiceModeHook interface.
sl@0	4218	This is used on Windows to avoid the various problems that people
sl@0	4219	have been seeing where the system hangs when tclsh is running
sl@0	4220	outside of the event loop. As part of this, renamed
sl@0	4221	TcapAlertNotifier back to Tcl_AlertNotifier since it is public.
sl@0	4222	(stanton)
sl@0	4223
sl@0	4224	3/23/99 (feature change) Test suite now uses "tcltest" namespace to
sl@0	4225	define the test procedure and other auxiliary procedures as well as
sl@0	4226	global variables. The previously chosen "test" namespace was thought
sl@0	4227	to be too generic and likely to create conflits.
sl@0	4228	(hirschl)
sl@0	4229	* POTENTIAL INCOMPATIBILITY *
sl@0	4230
sl@0	4231	3/24/99 (bug fix) Make sockets thread safe on Windows.
sl@0	4232	(redman)
sl@0	4233
sl@0	4234	3/24/99 (bug fix) Fix cases where expr would incorrect return
sl@0	4235	a floating point value instead of an integer. (stanton)
sl@0	4236
sl@0	4237	3/25/99 (bug fix) Added ASCII to big5 and gb2312 encodings.
sl@0	4238	(stanton)
sl@0	4239
sl@0	4240	3/25/99 (feature change) Changed so aliases are invoked at current
sl@0	4241	scope in the target interpreter instead of at the global scope. This
sl@0	4242	was an incompatibility introduced in 8.1 that is being removed.
sl@0	4243	(stanton)
sl@0	4244	* POTENTIAL INCOMPATIBILITY with previous beta releases *
sl@0	4245
sl@0	4246	3/26/99 (feature change) --enable-shared is now the default and build
sl@0	4247	Tcl as a shared library; specify --disable-shared to build a static Tcl
sl@0	4248	library and shell.
sl@0	4249	* POTENTIAL INCOMPATIBILITY *
sl@0	4250
sl@0	4251	3/29/99 (bug fix) Removed the stub functions and changed the stub
sl@0	4252	macros to just use the name without params. Pass &tclStubs into the
sl@0	4253	interp (don't use tclStubsPtr because of collisions with the stubs on
sl@0	4254	Solaris). (redman)
sl@0	4255
sl@0	4256	3/30/99 (bug fix) Loadable modules are now unloaded at the last
sl@0	4257	possible moment during Tcl_Finalize to fix various exit-time crashes.
sl@0	4258	(welch)
sl@0	4259
sl@0	4260	3/30/99 (bug fix) Tcl no longer calls setlocale(). It looks at
sl@0	4261	env(LANG) and env(LC_TYPE) instead. (stanton)
sl@0	4262
sl@0	4263	4/1/99 (bug fix) Fixed the Ultrix multiple symbol definition problem.
sl@0	4264	Now, even Tcl includes a copy of the Tcl stub library. (redman)
sl@0	4265
sl@0	4266	4/1/99 (bug fix) Internationalized the registry package.
sl@0	4267
sl@0	4268	4/1/99 (bug fix) Changed the implemenation of Tcl_ConditionWait and
sl@0	4269	Tcl_ConditionNotify on Windows. The new algorithm eliminates a race
sl@0	4270	condition and was suggested by Jim Davidson. (welch)
sl@0	4271
sl@0	4272	4/2/99 (new apis) Made various Unicode utility functions public.
sl@0	4273	Tcl_UtfToUniCharDString, Tcl_UniCharToUtfDString, Tcl_UniCharLen,
sl@0	4274	Tcl_UniCharNcmp, Tcl_UniCharIsAlnum, Tcl_UniCharIsAlpha,
sl@0	4275	Tcl_UniCharIsDigit, Tcl_UniCharIsLower, Tcl_UniCharIsSpace,
sl@0	4276	Tcl_UniCharIsUpper, Tcl_UniCharIsWordChar, Tcl_WinUtfToTChar,
sl@0	4277	Tcl_WinTCharToUtf (stanton)
sl@0	4278
sl@0	4279	4/2/99 (feature change) Add new DDE package and removed the Tk
sl@0	4280	send command from the Windows version. Changed DDE-based send
sl@0	4281	code into "dde eval" command. The DDE package can be loaded
sl@0	4282	into tclsh, not just wish. Windows only. (redman)
sl@0	4283
sl@0	4284	4/5/99 (bug fix) Changed safe-tcl so that the encoding command
sl@0	4285	is an alias that masks out the "encoding system" subcommand.
sl@0	4286	(redman)
sl@0	4287
sl@0	4288	4/5/99 (bug fix) Configure patches to improve support for
sl@0	4289	OS/390 and BSD/OS 4.*. (stanton)
sl@0	4290
sl@0	4291	4/5/99 (bug fix) Fixed crash in the clock command that occurred
sl@0	4292	with negative time values in timezones east of GMT. (stanton)
sl@0	4293
sl@0	4294	4/6/99 (bug fix) Moved the "array set" C level code into a common
sl@0	4295	routine (TclArraySet). The TclSetupEnv routine now uses this API to
sl@0	4296	create an env array w/ no elements. This fixes the bug caused when
sl@0	4297	every environ varaible is removed, and the Tcl env variable is
sl@0	4298	synched. If no environ vars existed, the Tcl env var would never be
sl@0	4299	created. (surles)
sl@0	4300
sl@0	4301	4/6/99 (bug fix) Made the Env module I18N compliant. (surles)
sl@0	4302
sl@0	4303	4/6/99 (bug fix) Changed the FindVariable routine to TclpFindVariable,
sl@0	4304	that now does a case insensitive string comparison on Windows, and not
sl@0	4305	on UNIX. (surles)
sl@0	4306
sl@0	4307	--------------- Released 8.1b3, April 6, 1999 ----------------------
sl@0	4308
sl@0	4309	4/9/99 (bug fix) Fixed notifier deadlock situation when the pipe used
sl@0	4310	to talk back notifier thread is filled with data. Found as a result of the
sl@0	4311	focus.test for Tk hanging. (redman)
sl@0	4312
sl@0	4313	4/13/99 (bug fix) Fixed bug where socket -async combined with
sl@0	4314	fileevent for writing did not work under Windows NT. (redman)
sl@0	4315
sl@0	4316	4/13/99 (encoding fix) Restored the double byte definition of GB2312
sl@0	4317	and added the EUC-CN encoding. EUC-CN is a variant of GB2312 that
sl@0	4318	shifts the characters into bytes with the high bit set and includes
sl@0	4319	ASCII as a subset. (stanton)
sl@0	4320
sl@0	4321	4/27/99 (bug fix) Added 'extern "C" {}' block around the stub table
sl@0	4322	pointer declaration so the stub library can be used from C++. (stanton)
sl@0	4323
sl@0	4324	--------------- Released 8.1 final, April 29, 1999 ----------------------
sl@0	4325
sl@0	4326	4/22/99 (bug fix) Changed Windows NT socket implementation to avoid
sl@0	4327	creating a communication window. This avoids the problem where the
sl@0	4328	system hangs waiting for tclsh to respond to a system-wide synchronous
sl@0	4329	broadcast (e.g. if you change system colors). (redman)
sl@0	4330
sl@0	4331	4/22/99 (bug fix) Added call to TclWinInit from TclpInitPlatform when
sl@0	4332	building a static library since DllMain will not be invoked. This
sl@0	4333	could break old code that explicitly called TclWinInit, but should be
sl@0	4334	simpler in the long run. (stanton)
sl@0	4335	* POTENTIAL INCOMPATIBILITY *
sl@0	4336
sl@0	4337	4/23/99 (bug fix) Added support for the koi8-r Cyrillic
sl@0	4338	encoding. [Bug: 1771] (stanton)
sl@0	4339
sl@0	4340	4/28/99 (bug fix) Changed internal Tcl_Obj usage to avoid freeing the
sl@0	4341	internal representation after the string representation has been
sl@0	4342	freed. This makes it easier to debug extensions. (stanton)
sl@0	4343
sl@0	4344	4/30/99 (bug fix) Fixed a memory leak in CommandComplete. (stanton)
sl@0	4345
sl@0	4346	5/3/99 (bug fix) Fixed a bug where the Tcl_ObjType was not being set
sl@0	4347	in a duplicated Tcl_Obj. [Bug: 1975, 2047] (stanton)
sl@0	4348
sl@0	4349	5/3/99 (bug fix) Changed Tcl_ParseCommand to avoid modifying eval'ed
sl@0	4350	strings that are already null terminated. [Bug: 1793] (stanton)
sl@0	4351
sl@0	4352	5/3/99 (new feature) Applied Jeff Hobbs's string patch which includes
sl@0	4353	the following changes:
sl@0	4354	- added new subcommands: equal, repeat, map, is, replace
sl@0	4355	- added -length option to "string compare\|equal"
sl@0	4356	- added -nocase option to "string compare\|equal\|match"
sl@0	4357	- string and list indices can be an integer or end?-integer?.
sl@0	4358	- added optional first and last index args to string toupper, et al.
sl@0	4359	See the string.n manual entry for more details about the new string
sl@0	4360	features. [Bug: 1845] (stanton)
sl@0	4361
sl@0	4362	5/6/99 (new feature) Added Tcl_UtfNcmp and Tcl_UtfNcasecmp to make Utf
sl@0	4363	string comparision easier. (stanton)
sl@0	4364
sl@0	4365	5/7/99 (bug fix) Improved OS/390 support. [Bug: 1976, 1997] (stanton)
sl@0	4366
sl@0	4367	5/12/99 (bug fix) Changed Windows initialization code to avoid using
sl@0	4368	GetUserName system call in favor of the env(USERNAME) variable. This
sl@0	4369	provides a significant startup speed improvement. (stanton)
sl@0	4370
sl@0	4371	5/12/99 (bug fix) Replaced the per-interpreter regexp cache with a
sl@0	4372	per-thread cache. Changed the Regexp object to take advantage of this
sl@0	4373	extra cache. Added a reference count to the TclRegexp type so regexps
sl@0	4374	can be shared by multiple objects. Removed the per-interp regexp cache
sl@0	4375	from the interpreter. Now regexps can be used with no need for an
sl@0	4376	interpreter. This set of changes should provide significant speed
sl@0	4377	improvements for many Tcl scripts. [Bug: 1063] (stanton)
sl@0	4378
sl@0	4379	5/14/99 (bug fix) Durining initialization on Unix, Tcl now extracts the
sl@0	4380	encoding subfield from the LANG/LC_ALL environment variables in cases
sl@0	4381	where the locale is not found in the built-in locale table. It also
sl@0	4382	attempts to initialize the locale subsystem so X11 is happy. [Bug: 1989]
sl@0	4383	(stanton)
sl@0	4384
sl@0	4385	5/14/99 (bug fix) Applied the patch to fix 100-year and 400-year
sl@0	4386	boundaries in leap year code, from Isaac Hollander. [Bug: 2066] (redman)

sl@0	4388	5/14/99 (bug fix) Fixed a crash caused by a failure to reset the result
sl@0	4389	before evaluating the test expression in an uncompiled for
sl@0	4390	statement. (stanton)
sl@0	4391
sl@0	4392	5/18/99 (bug fix) Modified initialization code on Windows to avoid
sl@0	4393	inherenting closed or invalid channels. If the standard input is
sl@0	4394	anything other than a console, file, serial port, or pipe, then we fall
sl@0	4395	back to the standard Tk window console. (stanton)
sl@0	4396
sl@0	4397	5/19/99 (bug fix) Added an extern "C" block around the entire tcl.h
sl@0	4398	header file to avoid C++ linkage issues. (redman)
sl@0	4399
sl@0	4400	5/19/99 (new feature) Applied Jeff Hobb's patch to add
sl@0	4401	Tcl_StringCaseMatch to support case insensitive glob style matching and
sl@0	4402	Tcl_UniCharIs* character classification functions. (stanton)
sl@0	4403
sl@0	4404	5/20/99 (bug fix) Added the directory containing the executuble and the
sl@0	4405	../lib directory relative to that to the auto_path variable. (redman)

sl@0	4425	reported wrong result on null strings. [Bug: 2138] (stanton)
sl@0	4426
sl@0	4427	6/4/99 (new feature) Windows build now uses Cygwin tools plus GNU
sl@0	4428	make and autoconf to build static/dynamic and debug/nodebug. (stanton)
sl@0	4429
sl@0	4430	6/7/99 (new feature) Optimized string index, length, range, and
sl@0	4431	append commands. Added a new Unicode object type. (hershey)
sl@0	4432
sl@0	4433	6/8/99 (bug fix) Rolled back Windows socket driver to 8.1.0
sl@0	4434	version. (stanton)
sl@0	4435
sl@0	4436	6/9/99 (new feature) Added Tcl_RegExpMatchObj and Tcl_RegExpGetInfo
sl@0	4437	to public Tcl API, these functions are needed by Expect. Changed
sl@0	4438	tools/genStubs.tcl to always write output in LF mode. (stanton)
sl@0	4439
sl@0	4440	6/14/99 (new feature) Merged string and Unicode object types. Added
sl@0	4441	new public Tcl API functions: Tcl_NewUnicodeObj, Tcl_SetUnicodeObj,
sl@0	4442	Tcl_GetUnicode, Tcl_GetUniChar, Tcl_GetCharLength, Tcl_GetRange,
sl@0	4443	Tcl_AppendUnicodeToObj. (hershey)

sl@0	4446	tcl.m4 and aclocal.m4 macro libraries for configure. (wart)
sl@0	4447
sl@0	4448	6/17/99 (new feature) Added new regexp interfaces: -expanded, -line,
sl@0	4449	-linestop, and -lineanchor switches. Renamed Tcl_RegExpMatchObj to
sl@0	4450	Tcl_RegExpExecObj and added new Tcl_RegExpMatchObj that is equivalent
sl@0	4451	to Tcl_RegExpMatch. Added public macros for regexp flags. Added
sl@0	4452	REG_BOSONLY flag to allow Expect to iterate through a string and only
sl@0	4453	find matches that start at the current position within the
sl@0	4454	string. (stanton)
sl@0	4455
sl@0	4456	6/21/99 (bug fix) Fixed memory leak in TclpThreadCreate where thread

sl@0	4477	6/29/99 (new feature) Added options to tcltest package: -preservecore,
sl@0	4478	-limitconstraints, -help, -file, -notfile, and flags. (jenn)
sl@0	4479
sl@0	4480	7/3/99 (new feature) Changed parsing of variable names to allow empty
sl@0	4481	array names. Now "$(foo)" is a variable reference. Previously you
sl@0	4482	had to use something line $::(foo), which is slower. This change was
sl@0	4483	requested by Jean-Luc Fontaine for his STOOOP package. (welch)
sl@0	4484
sl@0	4485	7/3/99 (new feature) Added Tcl_SetNotifier (public API) and
sl@0	4486	associated hook points in the notifiers to be able to replace the
sl@0	4487	notifier calls at runtime. The Xt notifier and test program use this
sl@0	4488	hook. (welch)
sl@0	4489
sl@0	4490	7/3/99 (new feature) Added a new variant of the "Trf core patch" from
sl@0	4491	Andreas Kupries that adds new C APIs Tcl_StackChannel,
sl@0	4492	Tcl_UnstackChannel, and Tcl_GetStackedChannel. This allows the Trf
sl@0	4493	extension to work without applying patches to the Tcl core. (welch)
sl@0	4494
sl@0	4495	7/6/99 (new feature) Added -timeout option to http.tcl to handle
sl@0	4496	timeouts that occur during connection attempts to hosts that are
sl@0	4497	down. (welch)
sl@0	4498
sl@0	4499	7/6/99 (bug fix) Applied new implementation of the Windows serial
sl@0	4500	port driver from Rolf Schroedter that fixes reading only one byte from
sl@0	4501	the port at a time. Uses polling every 10ms to implement
sl@0	4502	fileevents. [Bug: 1980 2217] (redman)
sl@0	4503
sl@0	4504	7/8/99 (bug fix) Applied fix for bug in DFA state caching under
sl@0	4505	lookahead conditions (regular expressions). [Bug: 2318] (stanton)
sl@0	4506
sl@0	4507	7/8/99 (bug fix) Fixed bug in string range bounds checking
sl@0	4508	code. (stanton)

sl@0	4517	also fixed a bug that caused TCL_LIBRARY to be ignored. (hershey)
sl@0	4518
sl@0	4519	7/21/99 (bug fix) Implemented modified socket driver for Windows that
sl@0	4520	uses a thread to manage the socket event window. Code works the same
sl@0	4521	on all supported versions of Windows and was based on original 8.1.0
sl@0	4522	code. [Bug: 2178 2256 2259 2329 2323 2355] (redman)
sl@0	4523
sl@0	4524	7/21/99 (new feature) Applied patch from Rolf Schroedter to add
sl@0	4525	-pollinterval option to fconfigure for Windows serial ports. Allows
sl@0	4526	the maxblocktime to be modified to control how often serial ports are
sl@0	4527	checked for fileevents. Also added documentation for \\.\comX
sl@0	4528	notation for opening serial ports on Windows. (redman)
sl@0	4529
sl@0	4530	7/21/99 (bug fix) Changed APIs in stub tables to use "unsigned long"
sl@0	4531	instead of the platform-specific "size_t", primarily after SunOS 4
sl@0	4532	users could no longer compile. (redman)
sl@0	4533
sl@0	4534	7/22/99 (bug fix) Fixed crashing during "array set a(b) {}".
sl@0	4535	[Bug: 2427] (redman)

sl@0	4538	permissions prior to running. [Bug: 2413] (redman)
sl@0	4539
sl@0	4540	7/22/99 (bug fix) Applied patch from Ulrich Ring to remove ANSI-style
sl@0	4541	prototypes in the code. [Bug: 2391] (redman)
sl@0	4542
sl@0	4543	7/22/99 (bug fix) Added #if blocks around #includes of sys/*.h header
sl@0	4544	files, to allow an extension author on Windows to use the MetroWerks
sl@0	4545	compiler. [Bug: 2385] (redman)
sl@0	4546
sl@0	4547	7/22/99 (bug fix) Fixed running the safe.test test suite, one change
sl@0	4548	to the Windows Makefile.in to fix paths and another in safe.test to
sl@0	4549	check for the tcl_platform(threaded) variable properly. (redman)

sl@0	4555	mutexes from the primary thread while waiting for the helper thread to
sl@0	4556	terminate. Fixes dual-CPU WinNT hangs, only one rare sporadic hang
sl@0	4557	that still exists with dual-CPU WinNT. Also fixed test cases so that
sl@0	4558	they would not depend as much on timing for dual-CPU WinNT. (redman)
sl@0	4559
sl@0	4560	7/27/99 (bug fix) Some test suite cleanup. (jenn)
sl@0	4561

sl@0	4578	wish. The command line was being primed with tclpip82.dll, but it was
sl@0	4579	ignored later.
sl@0	4580
sl@0	4581	7/30/99 (bug fix) Added functions to stub table, patch provided by Jan
sl@0	4582	Nijtmans. [Bug: 2445] (hobbs)
sl@0	4583
sl@0	4584	8/1/99 (bug fix) Changed Windows socket driver to terminate threads
sl@0	4585	by sending a message to the window rather than calling
sl@0	4586	TerminateThread(), which seems to leak about 4k from the helper
sl@0	4587	thread's stack space. (redman)
sl@0	4588
sl@0	4589	--------------- Released 8.2b2, August 5, 1999 ----------------------
sl@0	4590
sl@0	4591	8/4/99 (bug fix) Applied patches supplied by Henry Spencer to greatly
sl@0	4592	enhance performance of certain classes of regular expressions.
sl@0	4593	[Bug: 2440 2447] (stanton)
sl@0	4594

sl@0	4596	Windows. [Bug: 2455] (hobbs)
sl@0	4597
sl@0	4598	8/5/99 (bug fix) Fixed reference to bytes that might not be null
sl@0	4599	terminated in tclLiteral.c. [Bug: 2496] (hobbs)

sl@0	4602
sl@0	4603	8/9/99 (bug fix) Fixed test suite to handle larger integers
sl@0	4604	(64bit). Patch from Don Porter. (hobbs)
sl@0	4605
sl@0	4606	8/9/99 (documentation fix) Clarified Tcl_DecrRefCount docs
sl@0	4607	[Bug: 1952]. Clarified array pattern docs [Bug: 1330]. Fixed clock docs
sl@0	4608	[Bug: 693]. Fixed formatting errors [Bug: 2188 2189]. Fixed doc error

sl@0	4610
sl@0	4611	8/9/99 (bug fix) Fixed path handling in auto_execok [Bug: 1276] (hobbs)
sl@0	4612
sl@0	4613	8/9/99 (internal api change) Removed the TclpMutexLock and TclpMutexUnlock
sl@0	4614	APIs and added a new exported api, Tcl_GetAllocMutex. These APIs are all for
sl@0	4615	the mutex used in the simple memory allocators. By making this change
sl@0	4616	we are able to substitute different implementations of the thread-related
sl@0	4617	APIs without having to recompile the Tcl core. (welch)
sl@0	4618
sl@0	4619	8/9/99 (new C API) Tcl_GetChannelNames returns a list of open channel
sl@0	4620	names in the interpreter result. Still no Tcl-level version of this,
sl@0	4621	but server-like applications can use this to clean up files without
sl@0	4622	deleting interpreters. (welch)
sl@0	4623
sl@0	4624	8/9/99 (bug fix) Traces were not firing on "info exists", which used to
sl@0	4625	happen in Tcl 7.6 and earlier. An "info exists" now fires a read trace,
sl@0	4626	if defined. This makes it possible to fully implement variables that
sl@0	4627	are defined via traces. (welch)
sl@0	4628
sl@0	4629	8/10/99 (bug fix) Fixed Brent's changes so that they work on
sl@0	4630	Windows. (redman)
