sl@0: Recent user-visible changes to Tcl: sl@0: sl@0: RCS: @(#) $Id: changes,v 1.79.2.50 2007/05/16 22:13:07 das Exp $ sl@0: sl@0: 1. No more [command1] [command2] construct for grouping multiple sl@0: commands on a single command line. sl@0: sl@0: 2. Semi-colon now available for grouping commands on a line. sl@0: sl@0: 3. For a command to span multiple lines, must now use backslash-return sl@0: at the end of each line but the last. sl@0: sl@0: 4. "Var" command has been changed to "set". sl@0: sl@0: 5. Double-quotes now available as an argument grouping character. sl@0: sl@0: 6. "Return" may be used at top-level. sl@0: sl@0: 7. More backslash sequences available now. In particular, backslash-newline sl@0: may be used to join lines in command files. sl@0: sl@0: 8. New or modified built-in commands: case, return, for, glob, info, sl@0: print, return, set, source, string, uplevel. sl@0: sl@0: 9. After an error, the variable "errorInfo" is filled with a stack sl@0: trace showing what was being executed when the error occurred. sl@0: sl@0: 10. Command abbreviations are accepted when parsing commands, but sl@0: are not recommended except for purely-interactive commands. sl@0: sl@0: 11. $, set, and expr all complain now if a non-existent variable is sl@0: referenced. sl@0: sl@0: 12. History facilities exist now. See Tcl.man and Tcl_RecordAndEval.man. sl@0: sl@0: 13. Changed to distinguish between empty variables and those that don't sl@0: exist at all. Interfaces to Tcl_GetVar and Tcl_ParseVar have changed sl@0: (NULL return value is now possible). *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 14. Changed meaning of "level" argument to "uplevel" command (1 now means sl@0: "go up one level", not "go to level 1"; "#1" means "go to level 1"). sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 15. 3/19/90 Added "info exists" option to see if variable exists. sl@0: sl@0: 16. 3/19/90 Added "noAbbrev" variable to prohibit command abbreviations. sl@0: sl@0: 17. 3/19/90 Added extra errorInfo option to "error" command. sl@0: sl@0: 18. 3/21/90 Double-quotes now only affect space: command, variable, sl@0: and backslash substitutions still occur inside double-quotes. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 19. 3/21/90 Added support for \r. sl@0: sl@0: 20. 3/21/90 List, concat, eval, and glob commands all expect at least sl@0: one argument now. *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 21. 3/22/90 Added "?:" operators to expressions. sl@0: sl@0: 22. 3/25/90 Fixed bug in Tcl_Result that caused memory to get trashed. sl@0: sl@0: ------------------- Released version 3.1 --------------------- sl@0: sl@0: 23. 3/29/90 Fixed bug that caused "file a.b/c ext" to return ".b/c". sl@0: sl@0: 24. 3/29/90 Semi-colon is not treated specially when enclosed in sl@0: double-quotes. sl@0: sl@0: ------------------- Released version 3.2 --------------------- sl@0: sl@0: 25. 4/16/90 Rewrote "exec" not to use select or signals anymore. sl@0: Should be more Sys-V compatible, and no slower in the normal case. sl@0: sl@0: 26. 4/18/90 Rewrote "glob" to eliminate GNU code (there's no GNU code sl@0: left in Tcl, now), and added Tcl_TildeSubst procedure. Added automatic sl@0: tilde-substitution in many commands, including "glob". sl@0: sl@0: ------------------- Released version 3.3 --------------------- sl@0: sl@0: 27. 7/11/90 Added "Tcl_AppendResult" procedure. sl@0: sl@0: 28. 7/20/90 "History" with no options now defaults to "history info" sl@0: rather than to "history redo". Although this is a backward incompatibility, sl@0: it should only be used interactively and thus shouldn't present any sl@0: compatibility problems with scripts. sl@0: sl@0: 29. 7/20/90 Added "Tcl_GetInteger", "Tcl_GetDouble", and "Tcl_GetBoolean" sl@0: procedures. sl@0: sl@0: 30. 7/22/90 Removed "Tcl_WatchInterp" procedure: doesn't seem to be sl@0: necessary, since the same effect can be achieved with the deletion sl@0: callbacks on individual commands. *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 31. 7/23/90 Added variable tracing: Tcl_TraceVar, Tcl_UnTraceVar, sl@0: and Tcl_VarTraceInfo procedures, "trace" command. sl@0: sl@0: 32. 8/9/90 Mailed out list of all bug fixes since 3.3 release. sl@0: sl@0: 33. 8/29/90 Fixed bugs in Tcl_Merge relating to backslashes and sl@0: semi-colons. Mailed out patch. sl@0: sl@0: 34. 9/3/90 Fixed bug in tclBasic.c: quotes weren't quoting ]'s. sl@0: Mailed out patch. sl@0: sl@0: 35. 9/19/90 Rewrote exec to always use files both for input and sl@0: output to the process. The old pipe-based version didn't work if sl@0: the exec'ed process forked a child and then exited: Tcl waited sl@0: around for stdout to get closed, which didn't happen until the sl@0: grandchild exited. sl@0: sl@0: 36. 11/5/90 ERR_IN_PROGRESS flag wasn't being cleared soon enough sl@0: in Tcl_Eval, allowing error messages from different commands to sl@0: pile up in $errorInfo. Fixed by re-arranging code in Tcl_Eval that sl@0: re-initializes result and ERR_IN_PROGRESS flag. Didn't mail out sl@0: patch: changes too complicated to describe. sl@0: sl@0: 37. 12/19/90 Added Tcl_VarEval procedure as a convenience for sl@0: assembling and executing Tcl commands. sl@0: sl@0: 38. 1/29/91 Fixed core leak in Tcl_AddErrorInfo. Also changed procedure sl@0: and Tcl_Eval so that first call to Tcl_AddErrorInfo need not come from sl@0: Tcl_Eval. sl@0: sl@0: ----------------- Released version 5.0 with Tk ------------------ sl@0: sl@0: 39. 4/3/91 Removed change bars from manual entries, leaving only those sl@0: that came after version 3.3 was released. sl@0: sl@0: 40. 5/17/91 Changed tests to conform to Mary Ann May-Pumphrey's approach. sl@0: sl@0: 41. 5/23/91 Massive revision to Tcl parser to simplify the implementation sl@0: of string and floating-point support in expressions. Newlines inside sl@0: [] are now treated as command separators rather than word separators sl@0: (this makes newline treatment consistent throughout Tcl). sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 42. 5/23/91 Massive rewrite of expression code to support floating-point sl@0: values and simple string comparisons. The C interfaces to expression sl@0: routines have changed (Tcl_Expr is replaced by Tcl_ExprLong, Tcl_ExprDouble, sl@0: etc.), but all old Tcl expression strings should be accepted by the new sl@0: expression code. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 43. 5/23/91 Modified tclHistory.c to check for negative "keep" value. sl@0: sl@0: 44. 5/23/91 Modified Tcl_Backslash to handle backslash-newline. It now sl@0: returns 0 to indicate that a backslash sequence should be replaced by sl@0: no character at all. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 45. 5/29/91 Modified to use ANSI C function prototypes. Must set sl@0: "USE_ANSI" switch when compiling to get prototypes. sl@0: sl@0: 46. 5/29/91 Completed test suite by providing tests for all of the sl@0: built-in Tcl commands. sl@0: sl@0: 47. 5/29/91 Changed Tcl_Concat to eliminate leading and trailing sl@0: white-space in each of the things it concatenates and to ignore sl@0: elements that are empty or have only white space in them. This sl@0: produces cleaner output from the "concat" command. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 48. 5/31/91 Changed "set" command and Tcl_SetVar procedure to return sl@0: new value of variable. sl@0: sl@0: 49. 6/1/91 Added "while" and "cd" commands. sl@0: sl@0: 50. 6/1/91 Changed "exec" to delete the last character of program sl@0: output if it is a newline. In most cases this makes it easier to sl@0: process program-generated output. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 51. 6/1/91 Made sure that pointers are never used after freeing them. sl@0: sl@0: 52. 6/1/91 Fixed bug in TclWordEnd where it wasn't dealing with sl@0: [] inside quotes correctly. sl@0: sl@0: 53. 6/8/91 Fixed exec.test to accept return values of either 1 or sl@0: 255 from "false" command. sl@0: sl@0: 54. 7/6/91 Massive overhaul of variable management. Associative sl@0: arrays now available, along with "unset" command (and Tcl_UnsetVar sl@0: procedure). Variable traces have been completely reworked: sl@0: interfaces different both from Tcl and C, and multiple traces may sl@0: exist on same variable. Can no longer redefine existing local sl@0: variable to be global. Calling sequences have changed slightly sl@0: for Tcl_GetVar and Tcl_SetVar ("global" is now "flags"). Tcl_SetVar sl@0: can fail and return a NULL result. New forms of variable-manipulation sl@0: procedures: Tcl_GetVar2, Tcl_SetVar2, etc. Syntax of variable sl@0: $-notation changed to support array indexing. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 55. 7/6/91 Added new list-manipulation procedures: Tcl_ScanElement, sl@0: Tcl_ConvertElement, Tcl_AppendElement. sl@0: sl@0: 56. 7/12/91 Created new procedure Tcl_EvalFile, which does most of the sl@0: work of the "source" command. sl@0: sl@0: 57. 7/20/91 Major reworking of "exec" command to allow pipelines, sl@0: more redirection, background. Added new procedures Tcl_Fork, sl@0: Tcl_WaitPids, Tcl_DetachPids, and Tcl_CreatePipeline. The old sl@0: "< input" notation has been replaced by "<< input" ("<" is for sl@0: redirection from a file). Also handles error returns and abnormal sl@0: terminations (e.g. signals) differently. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 58. 7/21/91 Added "append" and "lappend" commands. sl@0: sl@0: 59. 7/22/91 Reworked error messages and manual entries to use sl@0: ?x? as the notation for an optional argument x, instead of [x]. The sl@0: bracket notation was often confused with the use of brackets for sl@0: command substitution. Also modified error messages to be more sl@0: consistent. sl@0: sl@0: 60. 7/23/91 Tcl_DeleteCommand now returns an indication of whether sl@0: or not the command actually existed, and the "rename" command uses sl@0: this information to return an error if an attempt is made to delete sl@0: a non-existent command. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 61. 7/25/91 Added new "errorCode" mechanism, along with procedures sl@0: Tcl_SetErrorCode, Tcl_UnixError, and Tcl_ResetResult. Renamed sl@0: Tcl_Return to Tcl_SetResult, but left a #define for Tcl_Return to sl@0: avoid compatibility problems. sl@0: sl@0: 62. 7/26/91 Extended "case" command with alternate syntax where all sl@0: patterns and commands are together in a single list argument: makes sl@0: it easier to write multi-line case statements. sl@0: sl@0: 63. 7/27/91 Changed "print" command to perform tilde-substitution on sl@0: the file name. sl@0: sl@0: 64. 7/27/91 Added "tolower", "toupper", "trim", "trimleft", and "trimright" sl@0: options to "string" command. sl@0: sl@0: 65. 7/29/91 Added "atime", "mtime", "size", and "stat" options to "file" sl@0: command. sl@0: sl@0: 66. 8/1/91 Added "split" and "join" commands. sl@0: sl@0: 67. 8/11/91 Added commands for file I/O, including "open", "close", sl@0: "read", "gets", "puts", "flush", "eof", "seek", and "tell". sl@0: sl@0: 68. 8/14/91 Switched to use a hash table for command lookups. Command sl@0: abbreviations no longer have direct support in the Tcl interpreter, but sl@0: it should be possible to simulate them with the auto-load features sl@0: described below. The "noAbbrev" variable is no longer used by Tcl. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 68.5 8/15/91 Added support for "unknown" command, which can be used to sl@0: complete abbreviations, auto-load library files, auto-exec shell sl@0: commands, etc. sl@0: sl@0: 69. 8/15/91 Added -nocomplain switch to "glob" command. sl@0: sl@0: 70. 8/20/91 Added "info library" option and TCL_LIBRARY #define. Also sl@0: added "info script" option. sl@0: sl@0: 71. 8/20/91 Changed "file" command to take "option" argument as first sl@0: argument (before file name), for consistency with other Tcl commands. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 72. 8/20/91 Changed format of information in $errorInfo variable: sl@0: comments such as sl@0: ("while" body line 1) sl@0: are now on separate lines from commands being executed. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 73. 8/20/91 Changed Tcl_AppendResult so that it (eventually) frees sl@0: large buffers that it allocates. sl@0: sl@0: 74. 8/21/91 Added "linsert", "lreplace", "lsearch", and "lsort" sl@0: commands. sl@0: sl@0: 75. 8/28/91 Added "incr" and "exit" commands. sl@0: sl@0: 76. 8/30/91 Added "regexp" and "regsub" commands. sl@0: sl@0: 77. 9/4/91 Changed "dynamic" field in interpreters to "freeProc" (procedure sl@0: address). This allows for alternative storage managers. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 78. 9/6/91 Added "index", "length", and "range" options to "string" sl@0: command. Added "lindex", "llength", and "lrange" commands. sl@0: sl@0: 79. 9/8/91 Removed "index", "length", "print" and "range" commands. sl@0: "Print" is redundant with "puts", but less general, and the other sl@0: commands are replaced with the new commands described in change 78 sl@0: above. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 80. 9/8/91 Changed history revision to occur even when history command sl@0: is nested; needed in order to allow "history" to be invoked from sl@0: "unknown" procedure. sl@0: sl@0: 81. 9/13/91 Changed "panic" not to use vfprintf (it's uglier and less sl@0: general now, but makes it easier to run Tcl on systems that don't sl@0: have vfprintf). Also changed "strerror" not to redeclare sys_errlist. sl@0: sl@0: 82. 9/19/91 Lots of changes to improve portability to different UNIX sl@0: systems, including addition of "config" script to adapt Tcl to the sl@0: configuration of the system it's being compiled on. sl@0: sl@0: 83. 9/22/91 Added "pwd" command. sl@0: sl@0: 84. 9/22/91 Renamed manual pages so that their filenames are no more sl@0: than 14 characters in length, moved to "doc" subdirectory. sl@0: sl@0: 85. 9/24/91 Redid manual entries so they contain the supplemental sl@0: macros that they need; can just print with "troff -man" or "man" sl@0: now. sl@0: sl@0: 86. 9/26/91 Created initial version of script library, including sl@0: a version of "unknown" that does auto-loading, auto-execution, and sl@0: abbreviation expansion. This library is used by tclTest sl@0: automatically. See the "library" manual entry for details. sl@0: sl@0: ----------------- Released version 6.0, 9/26/91 ------------------ sl@0: sl@0: 87. 9/30/91 Made "string tolower" and "string toupper" check case sl@0: before converting: on some systems, "tolower" and "toupper" assume sl@0: that character already has particular case. sl@0: sl@0: 88. 9/30/91 Fixed bug in Tcl_SetResult: wasn't always setting freeProc sl@0: correctly when called with NULL value. This tended to cause memory sl@0: allocation errors later. sl@0: sl@0: 89. 10/3/91 Added "upvar" command. sl@0: sl@0: 90. 10/4/91 Changed "format" so that internally it converts %D to %ld, sl@0: %U to %lu, %O to %lo, and %F to %f. This eliminates some compatibility sl@0: problems on some machines without affecting behavior. sl@0: sl@0: 91. 10/10/91 Fixed bug in "regsub" that caused core dumps with the -all sl@0: option when the last match wasn't at the end of the string. sl@0: sl@0: 92. 10/17/91 Fixed problems with backslash sequences: \r support was sl@0: incomplete and \f and \v weren't supported at all. sl@0: sl@0: 93. 10/24/91 Added Tcl_InitHistory procedure. sl@0: sl@0: 94. 10/24/91 Changed "regexp" to store "-1 -1" in subMatchVars that sl@0: don't match, rather than returning an error. sl@0: sl@0: 95. 10/27/91 Modified "regexp" to return actual strings in matchVar sl@0: and subMatchVars instead of indices. Added "-indices" switch to cause sl@0: indices to be returned. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 96. 10/27/91 Fixed bug in "scan" where it used hardwired constants for sl@0: sizes of floats and doubles instead of using "sizeof". sl@0: sl@0: 97. 10/31/91 Fixed bug in tclParse.c where parse-related error messages sl@0: weren't being storage-managed correctly, causing spurious free's. sl@0: sl@0: 98. 10/31/91 Form feed and vertical tab characters are now considered sl@0: to be space characters by the parser. sl@0: sl@0: 99. 10/31/91 Added TCL_LEAVE_ERR_MSG flag to procedures like Tcl_SetVar. sl@0: sl@0: 100. 11/7/91 Fixed bug in "case" where "in" argument couldn't be omitted sl@0: if all case branches were embedded in a single list. sl@0: sl@0: 101. 11/7/91 Switched to use "pid_t" and "uid_t" and other official sl@0: POSIC types and function prototypes. sl@0: sl@0: ----------------- Released version 6.1, 11/7/91 ------------------ sl@0: sl@0: 102. 12/2/91 Modified Tcl_ScanElement and Tcl_ConvertElement in several sl@0: ways. First, allowed caller to request that only backslashes be used sl@0: (no braces). Second, made Tcl_ConvertElement more aggressive in using sl@0: backslashes for braces and quotes. sl@0: sl@0: 103. 12/5/91 Added "type", "lstat", and "readlink" options to "file" sl@0: command, plus added new "type" element to output of "stat" and "lstat" sl@0: options. sl@0: sl@0: 104. 12/10/91 Manual entries had first lines that caused "man" program sl@0: to try weird preprocessor. Added blank comment lines to fix problem. sl@0: sl@0: 105. 12/16/91 Fixed a few bugs in auto_mkindex proc: wasn't handling sl@0: errors properly, and hadn't been upgraded for new "regexp" syntax. sl@0: sl@0: 106. 1/2/92 Fixed bug in "file" command where it didn't properly handle sl@0: a file names containing tildes where the indicated user doesn't exist. sl@0: sl@0: 107. 1/2/92 Fixed lots of cases in tclUnixStr.c where two different sl@0: errno symbols (e.g. EWOULDBLOCK and EAGAIN) have the same number; Tcl sl@0: will only use one of them. sl@0: sl@0: 108. 1/2/92 Lots of changes to configuration script to handle many more sl@0: systems more gracefully. E.g. should now detect the bogus strtoul that sl@0: comes with AIX and substitute Tcl's own version instead. sl@0: sl@0: ----------------- Released version 6.2, 1/10/92 ------------------ sl@0: sl@0: 109. 1/20/92 Config didn't have code to actually use "uid_t" variable sl@0: to set TCL_UIT_T #define. sl@0: sl@0: 110. 2/10/92 Tcl_Eval didn't properly reset "numLevels" variable when sl@0: too-deep recursion occurred. sl@0: sl@0: 111. 2/29/92 Added "on" and "off" to keywords accepted by Tcl_GetBoolean. sl@0: sl@0: 112. 3/19/92 Config wasn't installing default version of strtod.c for sl@0: systems that don't have one in libc.a. sl@0: sl@0: 113. 3/23/92 Fixed bug in tclExpr.c where numbers with leading "."s, sl@0: like 0.75, couldn't be properly substituted into expressions with sl@0: variable or command substitution. sl@0: sl@0: 114. 3/25/92 Fixed bug in tclUnixAZ.c where "gets" command wasn't sl@0: checking to make sure that it was able to write the variable OK. sl@0: sl@0: 115. 4/16/92 Fixed bug in tclUnixAZ.c where "read" command didn't sl@0: compute file size right for device files. sl@0: sl@0: 116. 4/23/92 Fixed but in tclCmdMZ.c where "trace vinfo" was overwriting sl@0: the trace command. sl@0: sl@0: ----------------- Released version 6.3, 5/1/92 ------------------ sl@0: sl@0: 117. 5/1/92 Added Tcl_GlobalEval. sl@0: sl@0: 118. 6/1/92 Changed auto-load facility to source files at global level. sl@0: sl@0: 119. 6/8/92 Tcl_ParseVar wasn't always setting termPtr after errors, which sl@0: sometimes caused core dumps. sl@0: sl@0: 120. 6/21/92 Fixed bug in initialization of regexp pattern cache. This sl@0: bug caused segmentation violations in regexp commands under some conditions. sl@0: sl@0: 121. 6/22/92 Changed implementation of "glob" command to eliminate sl@0: trailing slashes on directory names: they confuse some systems. There sl@0: shouldn't be any user-visible changes in functionality except for names sl@0: in error messages not having trailing slashes. sl@0: sl@0: 122. 7/2/92 Fixed bug that caused 'string match ** ""' to return 0. sl@0: sl@0: 123. 7/2/92 Fixed bug in Tcl_CreateCmdBuf where it wasn't initializing sl@0: the buffer to an empty string. sl@0: sl@0: 124. 7/6/92 Fixed bug in "case" command where it used NULL pattern string sl@0: after errors in the "default" clause. sl@0: sl@0: 125. 7/25/92 Speeded up auto_load procedure: don't reread all the index sl@0: files unless the path has changed. sl@0: sl@0: 126. 8/3/92 Changed tclUnix.h to define MAXPATHLEN from PATH_MAX, not sl@0: _POSIX_PATH_MAX. sl@0: sl@0: ----------------- Released version 6.4, 8/7/92 ------------------ sl@0: sl@0: 127. 8/10/92 Changed tclBasic.c so that comment lines can be continued by sl@0: putting a backslash before the newline. sl@0: sl@0: 128. 8/21/92 Modified "unknown" to allow the source-ing of a file for sl@0: an auto-load to trigger other nested auto-loads, as long as there isn't sl@0: any recursion on the same command name. sl@0: sl@0: 129. 8/25/92 Modified "format" command to allow " " and "+" flags, and sl@0: allow flags in any order. sl@0: sl@0: 130. 9/14/92 Modified Tcl_ParseVar so that it doesn't actually attempt sl@0: to look up the variable if "noEval" mode is in effect in the interpreter sl@0: (it just parses the name). This avoids the errors that used to occur sl@0: in statements like "expr {[info exists foo] && $foo}". sl@0: sl@0: 131. 9/14/92 Fixed bug in "uplevel" command where it didn't output the sl@0: correct error message if a level was specified but no command. sl@0: sl@0: 132. 9/14/92 Renamed manual entries to have extensions like .3 and .n, sl@0: and added "install" target to Makefile. sl@0: sl@0: 133. 9/18/92 Modified "unknown" command to emulate !!, !, and sl@0: ^^ csh history substitutions. sl@0: sl@0: 134. 9/21/92 Made the config script cleverer about figuring out which sl@0: switches to pass to "nm". sl@0: sl@0: 135. 9/23/92 Fixed tclVar.c to be sure to copy flags when growing variables. sl@0: Used to forget about traces in progress and make extra recursive calls sl@0: on trace procs. sl@0: sl@0: 136. 9/28/92 Fixed bug in auto_reset where it was unsetting variables sl@0: that might not exist. sl@0: sl@0: 137. 10/7/92 Changed "parray" library procedure to print any array sl@0: accessible to caller, local or global. sl@0: sl@0: 138. 10/15/92 Fixed bug where propagation of new environment variable sl@0: values among interpreters took N! time if there exist N interpreters. sl@0: sl@0: 139. 10/16/92 Changed auto_reset procedure so that it also deletes any sl@0: existing procedures that are in the auto_load index (the assumption is sl@0: that they should be re-loaded to get the latest versions). sl@0: sl@0: 140. 10/21/92 Fixed bug that caused lists to be incorrectly generated sl@0: for elements that contained backslash-newline sequences. sl@0: sl@0: 141. 12/9/92 Added support for TCL_LIBRARY environment variable: use sl@0: it as library location if it's present. sl@0: sl@0: 142. 12/9/92 Added "info complete" command, Tcl_CommandComplete procedure. sl@0: sl@0: 143. 12/16/92 Changed the Makefile to check to make sure "config" has been sl@0: run (can't run config directly from the Makefile because it modifies the sl@0: Makefile; thus make has to be run again after running config). sl@0: sl@0: ----------------- Released version 6.5, 12/17/92 ------------------ sl@0: sl@0: 144. 12/21/92 Changed config to look in several places for libc file. sl@0: sl@0: 145. 12/23/92 Added "elseif" support to if. Also, "then", "else", and sl@0: "elseif" may no longer be abbreviated. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 146. 12/28/92 Changed "puts" and "read" to support initial "-nonewline" sl@0: switch instead of additional "nonewline" argument. The old form is sl@0: still supported, but it is discouraged and is no longer documented. sl@0: Also changed "puts" to make the file argument default to stdout: e.g. sl@0: "puts foo" will print foo on standard output. sl@0: sl@0: 147. 1/6/93 Fixed bug whereby backslash-newline wasn't working when sl@0: typed interactively, or in "info complete". sl@0: sl@0: 148. 1/22/93 Fixed bugs in "lreplace" and "linsert" where close sl@0: quotes were being lost from last element before replacement or sl@0: insertion. sl@0: sl@0: 149. 1/29/93 Fixed bug in Tcl_AssembleCmd where it wasn't requiring sl@0: a newline at the end of a line before considering a command to be sl@0: complete. The bug caused some very long lines in script files to sl@0: be processed as multiple separate commands. sl@0: sl@0: 150. 1/29/93 Various changes in Makefile to add more configuration sl@0: options, simplify installation, fix bugs (e.g. don't use -f switch sl@0: for cp), etc. sl@0: sl@0: 151. 1/29/93 Changed "name1" and "name2" identifiers to "part1" and sl@0: "part2" to avoid name conflicts with stupid C++ implementations that sl@0: use "name1" and "name2" in a reserved way. sl@0: sl@0: 152. 2/1/93 Added "putenv" procedure to replace the standard system sl@0: version so that it will work correctly with Tcl's environment handling. sl@0: sl@0: ----------------- Released version 6.6, 2/5/93 ------------------ sl@0: sl@0: 153. 2/10/93 Fixed bugs in config script: missing "endif" in libc loop, sl@0: and tried to use strncasecmp.c instead of strcasecmp.c. sl@0: sl@0: 154. 2/10/93 Makefile improvements: added RANLIB variable for easier sl@0: Sys-V configuration, added SHELL variable for SGI systems. sl@0: sl@0: ----------------- Released version 6.7, 2/11/93 ------------------ sl@0: sl@0: 153. 2/6/93 Changes in backslash processing: sl@0: - \Cx, \Mx, \CMx, \e sequences no longer special sl@0: - \ also eats up any space after the newline, replacing sl@0: the whole sequence with a single space character sl@0: - Hex sequences like \x24 are now supported, along with ANSI C's \a. sl@0: - "format" no longer does backslash processing on its format string sl@0: - there is no longer any special meaning to a 0 return value from sl@0: Tcl_Backslash sl@0: - unknown backslash sequences, like (e.g. \*), are replaced with sl@0: the following character (e.g. *), instead of just treating the sl@0: backslash as an ordinary character. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 154. 2/6/93 Updated all copyright notices. The meaning hasn't changed sl@0: at all but the wording does a better job of protecting U.C. from sl@0: liability (according to U.C. lawyers, anyway). sl@0: sl@0: 155. 2/6/93 Changed "regsub" so that it overwrites the result variable sl@0: in all cases, even if there is no match. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 156. 2/8/93 Added support for XPG3 %n$ conversion specifiers to "format" sl@0: command. sl@0: sl@0: 157. 2/17/93 Fixed bug in Tcl_Eval where errors due to infinite sl@0: recursion could result in core dumps. sl@0: sl@0: 158. 2/17/93 Improved the auto-load mechanism to deal gracefully (i.e. sl@0: return an error) with a situation where a library file that supposedly sl@0: defines a procedure doesn't actually define it. sl@0: sl@0: 159. 2/17/93 Renamed Tcl_UnixError procedure to Tcl_PosixError, and sl@0: changed errorCode variable usage to use POSIX as keyword instead of sl@0: UNIX. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 160. 2/19/93 Changes to exec and process control: sl@0: - Added support for >>, >&, >>&, |&, <@, >@, and >&@ forms of redirection. sl@0: - When exec puts processes into background, it returns a list of sl@0: their pids as result. sl@0: - Added support for file, etc. (i.e. no space between sl@0: ">" and file name. sl@0: - Added -keepnewline option. sl@0: - Deleted Tcl_Fork and Tcl_WaitPids procedures (just use fork and sl@0: waitpid instead). sl@0: - Added waitpid compatibility procedure for systems that don't have sl@0: it. sl@0: - Added Tcl_ReapDetachedProcs procedure. sl@0: - Changed "exec" to return an error if there is stderr output, even sl@0: if the command returns a 0 exit status (it's always been documented sl@0: this way, but the implementation wasn't correct). sl@0: - If a process returns a non-zero exit status but doesn't generate sl@0: any diagnostic output, then Tcl generates an error message for it. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 161. 2/25/93 Fixed two memory-management problems having to do with sl@0: managing the old result during variable trace callbacks. sl@0: sl@0: 162. 3/1/93 Added dynamic string library: Tcl_DStringInit, Tcl_DStringAppend, sl@0: Tcl_DStringFree, Tcl_DStringResult, etc. sl@0: sl@0: 163. 3/1/93 Modified glob command to only return the names of files that sl@0: exist, and to only return names ending in "/" if the file is a directory. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 164. 3/19/93 Modified not to use system calls like "read" directly, sl@0: but instead to use special Tcl procedures that retry automatically sl@0: if interrupted by signals. sl@0: sl@0: 165. 4/3/93 Eliminated "noSep" argument to Tcl_AppendElement, plus sl@0: TCL_NO_SPACE flag for Tcl_SetVar and Tcl_SetVar2. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 166. 4/3/93 Eliminated "flags" and "termPtr" arguments to Tcl_Eval. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 167. 4/3/93 Changes to expressions: sl@0: - The "expr" command now accepts multiple arguments, which are sl@0: concatenated together with space separators. sl@0: - Integers aren't automatically promoted to floating-point if they sl@0: overflow the word size: errors are generated instead. sl@0: - Tcl can now handle "NaN" and other special values if the underlying sl@0: library procedures handle them. sl@0: - When printing floating-point numbers, Tcl ensures that there is a "." sl@0: or "e" in the number, so it can't be treated as an integer accidentally. sl@0: The procedure Tcl_PrintDouble is available to provide this function sl@0: in other contexts. Also, the variable "tcl_precision" can be used sl@0: to set the precision for printing (must be a decimal number giving sl@0: digits of precision). sl@0: - Expressions now support transcendental and other functions, e.g. sin, sl@0: acos, hypot, ceil, and round. Can add new math functions with sl@0: Tcl_CreateMathFunc(). sl@0: - Boolean expressions can now have any of the string values accepted sl@0: by Tcl_GetBoolean, such as "yes" or "no". sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 168. 4/5/93 Changed Tcl_UnsetVar and Tcl_UnsetVar2 to return TCL_OK sl@0: or TCL_ERROR instead of 0 or -1. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 169. 4/5/93 Eliminated Tcl_CmdBuf structure and associated procedures; sl@0: can use Tcl_DStrings instead. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 170. 4/8/93 Changed interface to Tcl_TildeSubst to use a dynamic sl@0: string for buffer space. This makes the procedure re-entrant and sl@0: thread-safe, whereas it wasn't before. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 171. 4/14/93 Eliminated tclHash.h, and moved everything from it to sl@0: tcl.h sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 172. 4/15/93 Eliminated Tcl_InitHistory, made "history" command always sl@0: be part of interpreter. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 173. 4/16/93 Modified "file" command so that "readable" option always sl@0: exists, even on machines that don't support symbolic links (always returns sl@0: same error as if the file wasn't a symbolic link). sl@0: sl@0: 174. 4/26/93 Fixed bugs in "regsub" where ^ patterns didn't get handled sl@0: right (pretended not to match when it really did, and looped infinitely sl@0: if -all was specified). sl@0: sl@0: 175. 4/29/93 Various improvements in the handling of variables: sl@0: - Can create variables and array elements during a read trace. sl@0: - Can delete variables during traces (note: unset traces will be sl@0: invoked when this happens). sl@0: - Can upvar to array elements. sl@0: - Can retarget an upvar to another variable by re-issuing the sl@0: upvar command with a different "other" variable. sl@0: sl@0: 176. 5/3/93 Added Tcl_GetCommandInfo, which returns info about a Tcl sl@0: command such as whether it exists and its ClientData. Also added sl@0: Tcl_SetCommandInfo, which allows any of this information to be modified sl@0: and also allows a command's delete procedure to have a different sl@0: ClientData value than its command procedure. sl@0: sl@0: 177. 5/5/93 Added Tcl_RegExpMatch procedure. sl@0: sl@0: 178. 5/6/93 Fixed bug in "scan" where it didn't properly handle sl@0: %% conversion specifiers. Also changed "scan" to use Tcl_PrintDouble sl@0: for printing real values. sl@0: sl@0: 179. 5/7/93 Added "-exact", "-glob", and "-regexp" options to "lsearch" sl@0: command to allow different kinds of pattern matching. sl@0: sl@0: 180. 5/7/93 Added many new switches to "lsort" to control the sorting sl@0: process: "-ascii", "-integer", "-real", "-command", "-increasing", sl@0: and "-decreasing". sl@0: sl@0: 181. 5/10/93 Changes to file I/O: sl@0: - Modified "open" command to support a list of POSIX access flags sl@0: like {WRONLY CREAT TRUNC} in addition to current fopen-style sl@0: access modes. Also added "permissions" argument to set permissions sl@0: of newly-created files. sl@0: - Fixed Scott Bolte's bug (can close stdin etc. in application and sl@0: then re-open them with Tcl commands). sl@0: - Exported access to Tcl's file table with new procedures Tcl_EnterFile sl@0: and Tcl_GetOpenFile. sl@0: sl@0: 182. 5/15/93 Added new "pid" command, which can be used to retrieve sl@0: either the current process id or a list of the process ids in a sl@0: pipeline opened with "open |..." sl@0: sl@0: 183. 6/3/93 Changed to use GNU autoconfig for configuration instead of sl@0: the home-brew "config" script. Also made many other configuration-related sl@0: changes, such as using instead of explicitly declaring system sl@0: calls in tclUnix.h. sl@0: sl@0: 184. 6/4/93 Fixed bug where core-dumps could occur if a procedure sl@0: redefined itself (the memory for the procedure's body could get sl@0: reallocated in the middle of evaluating the body); implemented sl@0: simple reference count mechanism. sl@0: sl@0: 185. 6/5/93 Changed tclIndex file format in two ways: (a) it's now sl@0: eval-ed instead of parsed, which makes it 3-4x faster; (b) the entries sl@0: in auto_index are now commands to evaluate, which allows commands to sl@0: be loaded in different ways such as dynamic-loading of C code. The sl@0: old tclIndex file format is still supported. sl@0: sl@0: 186. 6/7/93 Eliminated tclTest program, added new "tclsh" program sl@0: that is more like wish (allows script files to be invoked automatically sl@0: using "#!/usr/local/bin/tclsh", makes arguments available to script, sl@0: etc.). Added support for Tcl_AppInit plus default version; this sl@0: allows new Tcl applications to be created without modifying the sl@0: main program for tclsh. sl@0: sl@0: 187. 6/7/93 Fixed bug in TclWordEnd that kept backslash-newline from sl@0: working correctly in some cases during interactive input. sl@0: sl@0: 188. 6/9/93 Added Tcl_LinkVar and related procedures, which automatically sl@0: keep a Tcl variable in sync with a C variable. sl@0: sl@0: 189. 6/16/93 Increased maximum nesting depth from 100 to 1000. sl@0: sl@0: 190. 6/16/93 Modified "trace var" command so that error messages from sl@0: within traces are returned properly as the result of the variable sl@0: access, instead of the generic "access disallowed by trace command" sl@0: message. sl@0: sl@0: 191. 6/16/93 Added Tcl_CallWhenDeleted to provide callbacks when an sl@0: interpreter is deleted (same functionality as Tcl_WatchInterp, which sl@0: used to exist in versions before 6.0). sl@0: sl@0: 193. 6/16/93 Added "-code" argument to "return" command; it's there sl@0: primarily for completeness, so that procedures implementing control sl@0: constructs can reflect exceptional conditions back to their callers. sl@0: sl@0: 194. 6/16/93 Split up Tcl.n to make separate manual entries for each sl@0: Tcl command. Tcl.n now contains a summary of the language syntax. sl@0: sl@0: 195. 6/17/93 Added new "switch" command to replace "case": allows sl@0: alternate forms of pattern matching (exact, glob, regexp), replaces sl@0: pattern lists with single patterns (but you can use "-" bodies to sl@0: share one body among several patterns), eliminates "in" noise word. sl@0: "Case" command is now obsolete. sl@0: sl@0: 196. 6/17/93 Changed the "exec", "glob", "regexp", and "regsub" commands sl@0: to include a "--" switch. All initial arguments starting with "-" are now sl@0: treated as switches unless a "--" switch is present to end the list. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 197. 6/17/93 Changed auto-exec so that the subprocess gets stdin, stdout, sl@0: and stderr from the parent. This allows truly interactive sub-processes sl@0: (e.g. vi) to be auto-exec'ed from a tcl shell command line. sl@0: sl@0: 198. 6/18/93 Added patchlevel.h, for use in coordinating future patch sl@0: releases, and also added "info patchlevel" command to make the patch sl@0: level available to Tcl scripts. sl@0: sl@0: 199. 6/19/93 Modified "glob" command so that a leading "//" in a name sl@0: gets left as is (this is needed for systems like Apollos where "//" is sl@0: the super-root; Tcl used to collapse the two slashes into a single sl@0: slash). sl@0: sl@0: 200. 7/7/93 Added Tcl_SetRecursionLimit procedure so that the maximum sl@0: allowable nesting depth can be controlled for an interpreter from C. sl@0: sl@0: ----------------- Released version 7.0 Beta 1, 7/9/93 ------------------ sl@0: sl@0: 201. 7/12/93 Modified Tcl_GetInt and tclExpr.c so that full-precision sl@0: unsigned integers can be specified without overflow errors. sl@0: sl@0: 202. 7/12/93 Configuration changes: eliminate leading blank line in sl@0: configure script; provide separate targets in Makefile for installing sl@0: binary and non-binary information; check for size_t and a few other sl@0: potentially missing typedefs; don't put tclAppInit.o into libtcl.a; sl@0: better checks for matherr support. sl@0: sl@0: 203. 7/14/93 Changed tclExpr.c to check the termination pointer before sl@0: errno after strtod calls, to avoid problems with some versions of sl@0: strtod that set errno in unexpected ways. sl@0: sl@0: 204. 7/16/93 Changed "scan" command to be more ANSI-conformant: sl@0: eliminated %F, %D, etc., added code to ignore "l", "h", and "L" sl@0: modifiers but always convert %e, %f, and %g with implicit "l"; sl@0: also added support for %u and %i. Also changed "format" command sl@0: to eliminate %D, %U, %O, and add %i. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 205. 7/17/93 Changed "uplevel" and "upvar" so that they can be used sl@0: from global level to global level: this used to generate an error. sl@0: sl@0: 206. 7/19/93 Renamed "setenv", "putenv", and "unsetenv" procedures sl@0: to avoid conflicts with system procedures with the same names. If sl@0: you want Tcl's procedures to override the system procedures, do it sl@0: in the Makefile (instructions are in the Makefile). sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: ----------------- Released version 7.0 Beta 2, 7/21/93 ------------------ sl@0: sl@0: 207. 7/21/93 Fixed bug in tclVar.c where freed memory was accidentally sl@0: used if a procedure returned an element of a local array. sl@0: sl@0: 208. 7/22/93 Fixed bug in "unknown" where it didn't properly handle sl@0: errors occurring in the "auto_load" procedure, leaving its state sl@0: inconsistent. sl@0: sl@0: 209. 7/23/93 Changed exec's ">2" redirection operator to "2>" for sl@0: consistency with sh. This is incompatible with earlier beta releases sl@0: of 7.0 but not with pre-7.0 releases, which didn't support either sl@0: operator. sl@0: sl@0: 210. 7/28/93 Changed backslash-newline handling so that the resulting sl@0: space character *is* treated as a word separator unless the backslash sl@0: sequence is in quotes or braces. This is incompatible with 7.0b1 sl@0: and 7.0b2 but is more compatible with pre-7.0 versions that the b1 sl@0: and b2 releases were. sl@0: sl@0: 211. 7/28/93 Eliminated Tcl_LinkedVarWritable, added TCL_LINK_READ_ONLY to sl@0: Tcl_LinkVar to accomplish same purpose. This change is incompatible sl@0: with earlier beta releases, but not with releases before Tcl 7.0. sl@0: sl@0: 212. 7/29/93 Renamed regexp C functions so they won't clash with POSIX sl@0: regexp functions that use the same name. sl@0: sl@0: 213. 8/3/93 Added "-errorinfo" and "-errorcode" options to "return" sl@0: command: these allow for much better handling of the errorInfo sl@0: and errorCode variables in some cases. sl@0: sl@0: 214. 8/12/93 Changed "expr" so that % always returns a remainder with sl@0: the same sign as the divisor and absolute value smaller than the sl@0: divisor. sl@0: sl@0: 215. 8/14/93 Turned off auto-exec in "unknown" unless the command sl@0: was typed interactively. This means you must use "exec" when sl@0: invoking subprocesses, unless it's a command that's typed interactively. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 216. 8/14/93 Added support for tcl_prompt1 and tcl_prompt2 variables sl@0: to tclMain.c: makes prompts user-settable. sl@0: sl@0: 217. 8/14/93 Added asynchronous handlers (Tcl_AsyncCreate etc.) so sl@0: that signals can be taken cleanly by Tcl applications. sl@0: sl@0: 218. 8/16/93 Moved information about open files from the interpreter sl@0: structure to global variables so that a file can be opened in one sl@0: interpreter and read or written in another. sl@0: sl@0: 219. 8/16/93 Removed ENV_FLAGS from Makefile, so that there's no sl@0: official support for overriding setenv, unsetenv, and putenv. sl@0: sl@0: 220. 8/20/93 Various configuration improvements: coerce chars sl@0: to unsigned chars before using macros like isspace; source ~/.tclshrc sl@0: file during initialization if it exists and program is running sl@0: interactively; allow there to be directories in auto_path that don't sl@0: exist or don't have tclIndex files (ignore them); added Tcl_Init sl@0: procedure and changed Tcl_AppInit to call it. sl@0: sl@0: 221. 8/21/93 Fixed bug in expr where "+", "-", and " " were all sl@0: getting treated as integers with value 0. sl@0: sl@0: 222. 8/26/93 Added "tcl_interactive" variable to tclsh. sl@0: sl@0: 223. 8/27/93 Added procedure Tcl_FilePermissions to return whether a sl@0: given file can be read or written or both. Modified Tcl_EnterFile sl@0: to take a permissions mask rather than separate read and write arguments. sl@0: sl@0: 224. 8/28/93 Fixed performance bug in "glob" command (unnecessary call sl@0: to "access" for each file caused a 5-10x slow-down for big directories). sl@0: sl@0: ----------------- Released version 7.0 Beta 3, 8/28/93 ------------------ sl@0: sl@0: 225. 9/9/93 Renamed regexp.h to tclRegexp.h to avoid conflicts with system sl@0: include file by same name. sl@0: sl@0: 226. 9/9/93 Added Tcl_DontCallWhenDeleted. sl@0: sl@0: 227. 9/16/93 Changed not to call exit C procedure directly; instead sl@0: always invoke "exit" Tcl command so that application can redefine the sl@0: command to do additional cleanup. sl@0: sl@0: 228. 9/17/93 Changed auto-exec to handle names that contain slashes sl@0: (i.e. don't use PATH for them). sl@0: sl@0: 229. 9/23/93 Fixed bug in "read" and "gets" commands where they didn't sl@0: clear EOF conditions. sl@0: sl@0: ----------------- Released version 7.0, 9/29/93 ------------------ sl@0: sl@0: 230. 10/7/93 "Scan" command wasn't properly aligning things in memory, sl@0: so segmentation faults could arise under some circumstances. sl@0: sl@0: 231. 10/7/93 Fixed bug in Tcl_ConvertElement where it forgot to sl@0: backslash leading curly brace when creating lists. sl@0: sl@0: 232. 10/7/93 Eliminated dependency of tclMain.c on tclInt.h and sl@0: tclUnix.h, so that people can copy the file out of the Tcl source sl@0: directory to make modified private versions. sl@0: sl@0: 233. 10/8/93 Fixed bug in auto-loader that reversed the priority order sl@0: of entries in auto_path for new-style index files. Now things are sl@0: back to the way they were before 3.0: first in auto_path is always sl@0: highest priority. sl@0: sl@0: 234. 10/13/93 Fixed bug where Tcl_CommandComplete didn't recognize sl@0: comments and treat them as such. Thus if you typed the line sl@0: # { sl@0: interactively, Tcl would think that the command wasn't complete and sl@0: wait for more input before evaluating the script. sl@0: sl@0: 235. 10/14/93 Fixed bug where "regsub" didn't set the output variable sl@0: if the input string was empty. sl@0: sl@0: 236. 10/23/93 Fixed bug where Tcl_CreatePipeline didn't close off enough sl@0: file descriptors in child processes, causing children not to exit sl@0: properly in some cases. sl@0: sl@0: 237. 10/28/93 Changed "list" and "concat" commands not to generate sl@0: errors if given zero arguments, but instead to just return an empty sl@0: string. sl@0: sl@0: ----------------- Released version 7.1, 11/4/93 ------------------ sl@0: sl@0: Note: there is no 7.2 release. It was flawed and was thus withdrawn sl@0: shortly after it was released. sl@0: sl@0: 238. 11/10/93 TclMain.c didn't compile on some systems because of sl@0: R_OK in call to "access". Changed to eliminate call to "access". sl@0: sl@0: ----------------- Released version 7.3, 11/26/93 ------------------ sl@0: sl@0: 239. 11/6/93 Modified "lindex", "linsert", "lrange", and "lreplace" sl@0: so that "end" can be specified as an index. sl@0: sl@0: 240. 11/6/93 Modified "append" and "lappend" to allow only two sl@0: words total (i.e., nothing to append) without generating an error. sl@0: sl@0: 241. 12/2/93 Changed to use EAGAIN as the errno for non-blocking sl@0: I/O instead of EWOULDBLOCK: this should fix problem where non-blocking sl@0: I/O didn't work correctly on System-V systems. sl@0: sl@0: 242. 12/22/93 Fixed bug in expressions where cancelled evaluation sl@0: wasn't always working correctly (e.g. "set one 1; eval {1 || 1/$one}" sl@0: failed with a divide by zero error). sl@0: sl@0: 243. 1/6/94 Changed TCL_VOLATILE definition from -1 to the address of sl@0: a dummy procedure Tcl_Volatile, since -1 causes portability problems on sl@0: some machines (e.g., Crays). sl@0: sl@0: 244. 2/4/94 Added support for unary plus. sl@0: sl@0: 245. 2/17/94 Changed Tcl_RecordAndEval and "history" command to sl@0: call Tcl_GlobalEval instead of Tcl_Eval. Otherwise, invocation of sl@0: these facilities in nested procedures can cause unwanted results. sl@0: sl@0: 246. 2/17/94 Fixed bug in tclExpr.c where an expression such as sl@0: "expr {"12398712938788234-1298379" != ""}" triggers an integer sl@0: overflow error for the number in quotes, even though it isn't really sl@0: a proper integer anyway. sl@0: sl@0: 247. 2/19/94 Added new procedure Tcl_DStringGetResult to move result sl@0: from interpreter to a dynamic string. sl@0: sl@0: 248. 2/19/94 Fixed bug in Tcl_DStringResult that caused it to overwrite sl@0: the contents of a static result in some situations. This can cause sl@0: bizarre errors such as variables suddenly having empty values. sl@0: sl@0: 249. 2/21/94 Fixed bug in Tcl_AppendElement, Tcl_DStringAppendElement, sl@0: and the "lappend" command that caused improper omission of a separator sl@0: space in some cases. For example, the script sl@0: set x "abc{"; lappend x "def" sl@0: used to return the result "abc{def" instead of "abc{ def". sl@0: sl@0: 250. 3/3/94 Tcl_ConvertElement was outputting empty elements as \0 if sl@0: TCL_DONT_USE_BRACES was set. This depends on old pre-7.0 meaning of sl@0: \0, which is no longer in effect, so it didn't really work. Changed sl@0: to output empty elements as {} always. sl@0: sl@0: 251. 3/3/94 Renamed Tcl_DStringTrunc to Tcl_DStringSetLength and extended sl@0: it so that it can be used to lengthen a string as well as shorten it. sl@0: Tcl_DStringTrunc is defined as a macro for backward compatibility, but sl@0: it is deprecated. sl@0: sl@0: 252. 3/3/94 Added Tcl_AllowExceptions procedure. sl@0: sl@0: 253. 3/13/94 Fixed bug in Tcl_FormatCmd that could cause "format" sl@0: to mis-behave on 64-bit Big-Endian machines. sl@0: sl@0: 254. 3/13/94 Changed to use vfork instead of fork on systems where sl@0: vfork exists. sl@0: sl@0: 255. 3/23/94 Fixed bug in expressions where ?: didn't associate sl@0: right-to-left as they should. sl@0: sl@0: 256. 4/3/94 Fixed "exec" to flush any files used in >@ or >&@ sl@0: redirection in exec, so that data buffered for them is written sl@0: before any new data added by the subprocess. sl@0: sl@0: 257. 4/3/94 Added "subst" command. sl@0: sl@0: 258. 5/20/94 The tclsh main program is now called Tcl_Main; tclAppInit.c sl@0: has a "main" procedure that calls Tcl_Main. This makes it easier to use sl@0: Tcl with C++ programs, which need their own main programs, and it also sl@0: allows an application to prefilter the argument list before calling sl@0: Tcl_Main. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 259. 6/6/94 Fixed bug in procedure returns where the errorInfo variable sl@0: could get truncated if an unset trace was invoked as part of returning sl@0: from the procedure. sl@0: sl@0: 260. 6/13/94 Added "wordstart" and "wordend" options to "string" command. sl@0: sl@0: 261. 6/27/94 Fixed bug in expressions where they didn't properly cancel sl@0: the evaluation of math functions in &&, ||, and ?:. sl@0: sl@0: 262. 7/11/94 Incorrect boolean values, like "ogle", weren't being sl@0: handled properly. sl@0: sl@0: 263. 7/15/94 Added Tcl_RegExpCompile, Tcl_RegExpExec, and Tcl_RegExpRange, sl@0: which provide lower-level access to regular expression pattern matching. sl@0: sl@0: 264. 7/22/94 Fixed bug in "glob" command where "glob -nocomplain ~bad_user" sl@0: would complain about a missing user. Now it doesn't complain anymore. sl@0: sl@0: 265. 8/4/94 Fixed bug with linked variables where they didn't behave sl@0: correctly when accessed via upvars. sl@0: sl@0: 266. 8/17/94 Fixed bug in Tcl_EvalFile where it didn't clear interp->result. sl@0: sl@0: 267. 8/31/94 Modified "open" command so that errors in exec-ing sl@0: subprocesses are returned by the open immediately, rather than sl@0: being delayed until the "close" is executed. sl@0: sl@0: 268. 9/9/94 Modified "expr" command to generate errors for integer sl@0: overflow (includes addition, subtraction, negation, multiplication, sl@0: division). sl@0: sl@0: 269. 9/23/94 Modified "regsub" to return a count of the number of sl@0: matches and replacements, rather than 0/1. sl@0: sl@0: 279. 10/4/94 Added new features to "array" command: sl@0: - added "get" and "set" commands for easy conversion between arrays sl@0: and lists. sl@0: - added "exists" command to see if a variable is an array, changed sl@0: "names" and "size" commands to treat a non-existent array (or scalar sl@0: variable) just like an empty one. sl@0: - added pattern option to "names" command. sl@0: sl@0: 280. 10/6/94 Modified Tcl_SetVar2 so that read traces on variables get sl@0: called during append operations. sl@0: sl@0: 281. 10/20/94 Fixed bug in "read" command where reading from stdin sl@0: required two control-D's to stop the reading. sl@0: sl@0: 282. 11/3/94 Changed "expr" command to use longs for division just like sl@0: all other expr operators; it previously used ints for division. sl@0: sl@0: 283. 11/4/94 Fixed bugs in "unknown" procedure: it wasn't properly sl@0: handling exception returns from commands that were executed after sl@0: being auto-loaded. sl@0: sl@0: ----------------- Released version 7.4b1, 12/23/94 ------------------ sl@0: sl@0: 284. 12/26/94 Fixed "install" target in Makefile (couldn't always sl@0: find install program). sl@0: sl@0: 285. 12/26/94 Added strcncasecmp procedure to compat directory. sl@0: sl@0: 286. 1/3/95 Fixed all procedure calls to explicitly cast arguments: sl@0: implicit conversions from prototypes (especially integer->double) sl@0: don't work when compiling under non-ANSI compilers. Tcl is now clean sl@0: under gcc -Wconversion. sl@0: sl@0: 287. 1/4/95 Fixed problem in Tcl_ArrayCmd where same name was used for sl@0: both a label and a variable; caused problems on several older compilers, sl@0: making array command misbehave and causing many errors in Tcl test suite. sl@0: sl@0: ----------------- Released version 7.4b2, 1/12/95 ------------------ sl@0: sl@0: 288. 2/9/95 Modified Tcl_CreateCommand to return a token, and added sl@0: Tcl_GetCommandName procedure. Together, these procedures make it possible sl@0: to track renames of a command. sl@0: sl@0: 289. 2/13/95 Fixed bug in expr where "089" was interpreted as a sl@0: floating-point number rather than a bogus octal number. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 290. 2/14/95 Added code to Tcl_GetInt and Tcl_GetDouble to check for sl@0: overflows when reading in numbers. sl@0: sl@0: 291. 2/18/95 Changed "array set" to stop after first error, rather than sl@0: continuing after error. sl@0: sl@0: 292. 2/20/95 Upgraded to use autoconf version 2.2. sl@0: sl@0: 293. 2/20/95 Fixed core dump that could occur in "scan" command if a sl@0: close bracket was omitted. sl@0: sl@0: 294. 2/27/95 Changed Makefile to always use install-sh for installations: sl@0: there's just too much variation among "install" system programs, which sl@0: makes installation flakey. sl@0: sl@0: ----------------- Released version 7.4b3, 3/24/95 ------------------ sl@0: sl@0: 3/25/95 (bug fix) Changed "install" to "./install" in Makefile so that sl@0: "make install" will work even when "." isn't in the search path. sl@0: sl@0: 3/29/95 (bug fix) Fixed bug where the auto-loading mechanism wasn't sl@0: protecting the values of the errorCode and errorInfo variables. sl@0: sl@0: 3/29/95 (new feature) Added optional pattern argument to "parray" procedure. sl@0: sl@0: 3/29/95 (bug fix) Made the full functionality of sl@0: "return -code ... -errorcode ..." sl@0: work not just inside procedures, but also in sourced files and at sl@0: top level. sl@0: sl@0: 4/6/95 (new feature) Added "pattern" option to "array names" command. sl@0: sl@0: 4/18/95 (bug fix) Fixed bug in parser where it didn't allow backslash-newline sl@0: immediately after an argument in braces or quotes. sl@0: sl@0: 4/19/95 (new feature) Added tcl_library variable, which application can sl@0: set to override default library directory. sl@0: sl@0: 4/30/95 (bug fix) During trace callbacks for array elements, the variable sl@0: name used in the original reference would be temporarily modified to sl@0: separate the array name and element name; if the trace callback used sl@0: the same name string, it would get the wrong name (the array name without sl@0: element). Fixed to restore the variable name before making trace sl@0: callbacks. sl@0: sl@0: 4/30/95 (new feature) Added -nobackslashes, -nocommands, and -novariables sl@0: switches to "subst" command. sl@0: sl@0: 5/4/95 (new feature) Added TCL_EVAL_GLOBAL flag to Tcl_RecordAndEval. sl@0: sl@0: 5/5/95 (bug fix) Format command would overrun memory when printing sl@0: integers with very large precision, as in "format %.1000d 0". sl@0: sl@0: 5/5/95 (portability improvement) Changed to use BSDgettimeofday on sl@0: IRIX machines, to avoid compilation problems with the gettimeofday sl@0: declaration. sl@0: sl@0: 5/6/95 (bug fix) Changed manual entries to use the standard .TH sl@0: macro instead of a custom .HS macro; the .HS macro confuses index sl@0: generators like makewhatis. sl@0: sl@0: 5/9/95 (bug fix) Modified configure script to check for Solaris bug sl@0: that makes vfork unreliable (core dumps result if vforked child sl@0: changes a signal handler); will use fork instead of vfork if the sl@0: bug is present. sl@0: sl@0: 6/5/95 (bug fix) Modified "lsort" command to disallow recursive calls sl@0: to lsort from a comparison function. This is needed because qsort sl@0: is not reentrant. sl@0: sl@0: 6/5/95 (bug fix) Undid change 243 above: changed TCL_VOLATILE and sl@0: TCL_DYNAMIC back to integer constants rather than procedure addresses. sl@0: This was needed because procedure addresses can have multiple values sl@0: under some dynamic loading systems (e.g. SunOS 4.1 and Windows). sl@0: sl@0: 6/8/95 (feature change) Modified interface to Tcl_Main to pass in the sl@0: address of the application-specific initialization procedure. sl@0: Tcl_AppInit is no longer hardwired into Tcl_Main. This is needed sl@0: in order to make Tcl a shared library. sl@0: sl@0: 6/8/95 (feature change) Modified Makefile so that the installed versions sl@0: of tclsh and libtcl.a have version number in them (e.g. tclsh7.4 and sl@0: libtcl7.4.a) and the library directory name also has an embedded version sl@0: number (e.g., /usr/local/lib/tcl7.4). This should make it easier for sl@0: Tcl 7.4 to coexist with earlier versions. sl@0: sl@0: ----------------- Released version 7.4b4, 6/16/95 ------------------ sl@0: sl@0: 6/19/95 (bug fix) Fixed bugs in tclCkalloc.c that caused core dumps sl@0: if TCL_MEM_DEBUG was enabled on word-addressed machines such as Crays. sl@0: sl@0: 6/21/95 (feature removal) Removed overflow checks for integer arithmetic: sl@0: they just cause too much trouble (e.g. for random number generators). sl@0: sl@0: 6/28/95 (new features) Added tcl_patchLevel and tcl_version variables, sl@0: for consistency with Tk. sl@0: sl@0: 6/29/95 (bug fix) Fixed problem in Tcl_Eval where it didn't record sl@0: the right termination character if a script ended with a comment. This sl@0: caused erroneous output for the following command, among others: sl@0: puts "[ sl@0: expr 1+1 sl@0: # duh! sl@0: ]" sl@0: sl@0: 6/29/95 (message change) Changed the error message for ECHILD slightly sl@0: to provide a hint about why the problem is occurring. sl@0: sl@0: ----------------- Released version 7.4, 7/1/95 ------------------ sl@0: sl@0: 7/18/95 (bug fix) Changed "lreplace" so that nothing is deleted if sl@0: the last index is less than the first index or if the last index sl@0: is < 0. sl@0: sl@0: 7/18/95 (bug fix) Fixed bugs with backslashes in comments: sl@0: Tcl_CommandComplete (and "info complete") didn't properly handle sl@0: strings ending in backslash-newline, and neither Tcl_CommandComplete sl@0: nor the Tcl parser handled other backslash sequences right, such sl@0: as two backslashes before a newline. sl@0: sl@0: 7/19/95 (bug fix) Modified Tcl_DeleteCommand to delete the hash table sl@0: entry for the command before invoking its callback. This is needed in sl@0: order to deal with reentrancy. sl@0: sl@0: 7/22/95 (bug fix) "exec" wasn't reaping processes correctly after sl@0: certain errors (e.g. if the name of the executable was bogus, as sl@0: in "exec foobar"). sl@0: sl@0: 7/27/95 (bug fix) Makefile.in wasn't using the LIBS variable provided sl@0: by the "configure" script. This caused problems on some SCO systems. sl@0: sl@0: 7/27/95 (bug fix) The version of strtod in fixstrtod.c didn't properly sl@0: handle the case where endPtr == NULL. sl@0: sl@0: ----------------- Released patch 7.4p1, 7/29/95 ----------------------- sl@0: sl@0: 8/4/95 (bug fix) C-level trace callbacks for variables were sometimes sl@0: receiving the PART1_NOT_PARSED flag, which could cause errors in sl@0: subsequent Tcl library calls using the flags. (JO) sl@0: sl@0: 8/4/95 (bug fix) Calls to toupper and tolower weren't using the sl@0: UCHAR macros, which caused trouble in non-U.S. locales. (JO) sl@0: sl@0: 8/10/95 (new feature) Added the "load" command for dynamic loading of sl@0: binary packages, and the Tcl_PackageInitProc prototype for package sl@0: initialization procedures. (JO) sl@0: sl@0: 8/23/95 (new features) Added "info sharedlibextension" and sl@0: "info nameofexecutable" commands, plus Tcl_FindExtension procedure. (JO) sl@0: sl@0: 8/25/95 (bug fix) If the target of an "upvar" was non-existent but sl@0: had traces set, the traces were silently lost. Change to generate sl@0: an error instead. (JO) sl@0: sl@0: 8/25/95 (bug fix) Undid change from 7/19, so that commands can stay sl@0: around while their deletion callbacks execute. Added lots of code to sl@0: handle all of the reentrancy problems that this opens up. (JO) sl@0: sl@0: 8/25/95 (bug fix) Fixed core dump that could occur in TclDeleteVars sl@0: if there was an upvar from one entry in the table to the next entry sl@0: in the same table. (JO) sl@0: sl@0: 8/28/95 (bug fix) Exec wasn't handling bad user names properly, as sl@0: in "exec ~bogus_user/foo". (JO) sl@0: sl@0: 8/29/95 (bug fixes) Changed backslash-newline handling to correct two sl@0: problems: sl@0: - Only spaces and tabs following the backslash-newline are now sl@0: absorbed as part of the backslash-newline. Newlinew are no sl@0: longer absorbed (add another backslash if you want to absorb sl@0: another newline). sl@0: - TclWordEnd returns the character just before the backslash in sl@0: the sequence as the end of the sequence; it used to not consider sl@0: the backslash-newline as a word separator. (JO) sl@0: sl@0: 8/31/95 (new feature) Changed man page installation (with "mkLinks" sl@0: script) to create additional links for manual pages corresponding to sl@0: each of the procedure and command names described in the pages. (JO) sl@0: sl@0: 9/10/95 Reorganized Tcl sources for Windows and Mac ports. All sources sl@0: are now in subdirectories: "generic" contains sources that work on all sl@0: platforms, "windows", "mac", and "unix" directories contain platform- sl@0: specific sources. Some UNIX sources are also used on other platforms. (SS) sl@0: sl@0: 9/10/95 (feature change) Eliminated exported global variables (they sl@0: don't work with Windows DLLs). Replaced tcl_AsyncReady and sl@0: tcl_FileCloseProc with procedures Tcl_AsyncReady() and sl@0: Tcl_SetFileCloseProc(). Replaced C variable tcl_RcFileName with sl@0: a Tcl variable tcl_rcFileName. (SS) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 9/11/95 (new feature) Added procedure Tcl_SetPanicProc to override sl@0: the default implementation of "panic". (SS) sl@0: sl@0: 9/11/95 (new feature) Added "interp" command to allow creation of sl@0: new interpreters and execution of untrusted scripts. Added many new sl@0: procedures, such as Tcl_CreateSlave, Tcl_CreateAlias,and Tcl_MakeSafe, sl@0: to provide C-level access to the interpreter facility. This mechanism sl@0: now provides almost all of the generic functions of Borenstein's and sl@0: Rose's Safe-Tcl (but not any Tk or email-related stuff). (JL) sl@0: sl@0: 9/11/95 (feature change) Changed file management so that files are sl@0: no longer shared between interpreters: a file cannot normally be sl@0: referenced in one interpreter if it was opened in another. This sl@0: feature is needed to support safe interpreters. Added Tcl_ShareHandle() sl@0: procedure for allowing files to be shared, and added "interp" argument sl@0: to Tcl_FilePermissions procedure. (JL) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 9/11/95 (new feature) Added "AssocData" mechanism, whereby extensions sl@0: can associate their own data with an interpreter and get called back sl@0: when the interpreter is deleted. This is visible at C level via the sl@0: procedures Tcl_SetAssocData and Tcl_GetAssocData. (JL) sl@0: sl@0: 9/11/95 (new feature) Added Tcl_ErrnoMsg to translate an errno value sl@0: into a human-readable string. This is now used instead of calling sl@0: strerror because strerror mesages vary dramatically from platform sl@0: to platform, which messes up Tcl tests. Tcl_ErrnoMsg uses the standard sl@0: POSIX messages for all the common signals, and calls strerror for sl@0: signals it doesn't understand. sl@0: sl@0: ----------------- Released patch 7.4p2, 9/15/95 ----------------------- sl@0: sl@0: ----------------- Released 7.5a1, 9/15/95 ----------------------- sl@0: sl@0: 9/22/95 (bug fix) Changed auto_mkindex to create tclIndex files that sl@0: handle directories whose paths might contain spaces. (RJ) sl@0: sl@0: 9/27/95 (bug fix) The "format" command didn't check for huge or negative sl@0: width specifiers, which could cause core dumps. (JO) sl@0: sl@0: 9/27/95 (bug fix) Core dumps could occur if an interactive command typed sl@0: to tclsh returned a very long result for tclsh to print out. The bug is sl@0: actually in printf (in Solaris 2.3 and 2.4, at least); switched to use sl@0: puts instead. (JO) sl@0: sl@0: 9/28/95 (bug fix) Changed makefile.bc to eliminate a false dependency sl@0: for tcl1675.dll on the Borland run time library. (SS) sl@0: sl@0: 9/28/95 (bug fix) Fixed tcl75.dll so it looks for tcl1675.dll instead sl@0: of tcl16.dll. (SS) sl@0: sl@0: 9/28/95 (bug fix) Tcl was not correctly detecting the difference sl@0: between Win32s and Windows '95. (SS) sl@0: sl@0: 9/28/95 (bug fix) "exec" was not passing environment changes to child sl@0: processes under Windows. (SS) sl@0: sl@0: 9/28/95 (bug fix) Changed Tcl to ensure that open files are not passed sl@0: to child processes under Windows. (SS) sl@0: sl@0: 9/28/95 (bug fix) Fixed Windows '95 and NT versions of exec so it can sl@0: handle both console and windows apps. (SS) sl@0: sl@0: 9/28/95 (bug fix) Fixed Windows version of exec so it no longer leaves sl@0: temp files lying around. Also changed it so the temp files are sl@0: created in the appropriate system dependent temp directory. (SS) sl@0: sl@0: 9/28/95 (bug fix) Eliminated source dependency on the Win32s Universal sl@0: Thunk header file, since it is not bundled with VC++. (SS) sl@0: sl@0: 9/28/95 (bug fix) Under Windows, Tcl now constructs the HOME sl@0: environment variable from HOMEPATH and HOMEDRIVE when HOME is not sl@0: already set. (SS) sl@0: sl@0: 9/28/95 (bug fix) Added support for "info nameofexecutable" and "info sl@0: sharedlibextension" to the Windows version. (SS) sl@0: sl@0: 9/28/95 (bug fix) Changed tclsh to correctly parse command line sl@0: arguments so that backslashes are preserved under Windows. (SS) sl@0: sl@0: 9/29/95 (bug fix) Tcl 7.5a1 treated either return or newline as end sl@0: of line in "gets", which caused lines ending in CRLF to be treated as sl@0: two separate lines. Changed to allow only character as end-of-line: sl@0: carriage return on Macs, newline elsewhere. (JO) sl@0: sl@0: 9/29/95 (new feature) Changed to install "configInfo" file in same sl@0: directory as library scripts. It didn't used to get installed. (JO) sl@0: sl@0: 9/29/95 (bug fix) Tcl was not converting Win32 errors into POSIX sl@0: errors under some circumstances. (SS) sl@0: sl@0: 10/2/95 (bug fix) Safe interpreters no longer get initialized with sl@0: a call to Tcl_Init(). (JL) sl@0: sl@0: 10/1/95 (new feature) Added "tcl_platform" global variable to provide sl@0: environment information such as the instruction set and operating sl@0: system. (JO) sl@0: sl@0: 10/1/95 (bug fix) "exec" command wasn't always generating the sl@0: "child process exited abnormally" message when it should have. (JO) sl@0: sl@0: 10/2/95 (bug fix) Changed "mkLinks.tcl" so that the scripts it generates sl@0: won't create links that overwrite original manual entries (there was sl@0: a problem where pack-old.n was overwriting pack.n). (JO) sl@0: sl@0: 10/2/95 (feature change) Changed to use -ldl for dynamic loading under sl@0: Linux if it is available, but fall back to -ldld if it isn't. (JO) sl@0: sl@0: 10/2/95 (bug fix) File sharing was causing refcounts to reach 0 sl@0: prematurely for stdin, stdout and stderr, under some circumstances. (JL) sl@0: sl@0: 10/2/95 (platform support) Added support for Visual C++ compiler on sl@0: Windows, Windows '95 and Windows NT, code donated by Gordon Chaffee. (JL) sl@0: sl@0: 10/3/95 (bug fix) Tcl now frees any libraries that it loads before it sl@0: exits. (SS) sl@0: sl@0: 10/03/95 (bug fix) Fixed bug in Macintosh ls command where the -l sl@0: and -C options would fail in anything but the HOME directory. (RJ) sl@0: sl@0: ----------------- Released 7.5a2, 10/6/95 ----------------------- sl@0: sl@0: 10/10/95 (bug fix) "file dirnam /." was returning ":" on UNIX instead sl@0: of "/". (JO) sl@0: sl@0: 10/13/95 (bug fix) Eliminated dependency on MKS toolkit for generating sl@0: the tcl.def file from Borland object files. (SS) sl@0: sl@0: 10/17/95 (new features) Moved the event loop from Tcl to Tk, made major sl@0: revisions along the way: sl@0: - New Tcl commands: after, update, vwait (replaces "tkwait variable"). sl@0: - "tkerror" is now replaced with "bgerror". sl@0: - The following procedures are similar to their old Tk counterparts: sl@0: Tcl_DoOneEvent, Tcl_Sleep, Tcl_DoWhenIdle, Tcl_CancelIdleCall, sl@0: Tcl_CreateFileHandler, Tcl_DeleteFileHandler, Tcl_CreateTimerHandler, sl@0: Tcl_DeleteTimerHandler, Tcl_BackgroundError. sl@0: - Revised notifier, add new concept of "event source" with the following sl@0: procedures: Tcl_CreateEventSource, Tcl_DeleteEventSource, sl@0: Tcl_WatchFile, Tcl_SetMaxBlockTime, Tcl_FileReady, Tcl_QueueEvent, sl@0: Tcl_WaitForEvent. (JO) sl@0: sl@0: 10/31/95 (new features) Implemented cross platform file name support to make sl@0: it easier to write cross platform scripts. Tcl now understands 4 file naming sl@0: conventions: Windows (both DOS and UNC), Mac, Unix, and Network. The network sl@0: convention is a new naming mechanism that can be used to paths in a platform sl@0: independent fashion. See the "file" command manual page for more details. sl@0: The primary interfaces changes are: sl@0: - All Tcl commands that expect a file name now accept both network and sl@0: native form. sl@0: - Two new "file" subcommands, "nativename" and "networkname", provide a sl@0: way to convert between network and native form. sl@0: - Renamed Tcl_TildeSubst to Tcl_TranslateFileName, and changed it so that sl@0: it always returns a filename in native form. Tcl_TildeSubst is defined sl@0: as a macro for backward compatibility, but it is deprecated. (SS) sl@0: sl@0: 11/5/95 (new feature) Made "tkerror" and "bgerror" synonyms, so that sl@0: either name can be used to manipulate the command (provides temporary sl@0: backward compatibility for existing scripts that use tkerror). (JO) sl@0: sl@0: 11/5/95 (new feature) Added exit handlers and new C procedures sl@0: Tcl_CreateExitHandler, Tcl_DeleteExitHandler, and Tcl_Exit. (JO) sl@0: sl@0: 11/6/95 (new feature) Added pid command for Macintosh version of sl@0: Tcl (it didn't previously exist on the Mac). (RJ) sl@0: sl@0: 11/7/95 (new feature) New generic IO facility and support for IO to sl@0: files, pipes and sockets based on a common buffering scheme. Support sl@0: for asynchronous (non-blocking) IO and for event driver IO. Support sl@0: for automatic (background) asynchronous flushing and asynchronous sl@0: closing of channels. (JL) sl@0: sl@0: 11/7/95 (new feature) Added new commands "fconfigure" and "fblocked" sl@0: to support new I/O features such as nonblocking I/O. Added "socket" sl@0: command for creating TCP client and server sockets. (JL). sl@0: sl@0: 11/7/95 (new feature) Complete set of C APIs to the new generic IO sl@0: facility: sl@0: - Opening channels: Tcl_OpenFileChannel, Tcl_OpenCommandChannel, sl@0: Tcl_OpenTcpClient, Tcl_OpenTcpServer. sl@0: - I/O procedures on channels, which roughly mirror the ANSI C stdio sl@0: library: Tcl_Read, Tcl_Gets, Tcl_Write, Tcl_Flush, Tcl_Seek, sl@0: Tcl_Tell, Tcl_Close, Tcl_Eof, Tcl_InputBlocked, Tcl_GetChannelOption, sl@0: Tcl_SetChannelOption. sl@0: - Extension mechanism for creating new kinds of channels: sl@0: Tcl_CreateChannel, Tcl_GetChannelInstanceData, Tcl_GetChannelType, sl@0: Tcl_GetChannelName, Tcl_GetChannelFile, Tcl_RegisterChannel, sl@0: Tcl_UnregisterChannel, Tcl_GetChannel. sl@0: - Event-driven I/O on channels: Tcl_CreateChannelHandler, sl@0: Tcl_DeleteChannelHandler. (JL) sl@0: sl@0: 11/7/95 (new feature) Channel driver interface specification to allow sl@0: new types of channels to be added easily to Tcl. Currently being used sl@0: in three drivers - for files, pipes and TCP-based sockets. (JL). sl@0: sl@0: 11/7/95 (new feature) interp delete now takes any number of path sl@0: names of interpreters to delete, including zero. (JL). sl@0: sl@0: 11/8/95 (new feature) implemented 'info hostname' and Tcl_GetHostName sl@0: command to get host name of machine on which the Tcl process is running. (JL) sl@0: sl@0: 11/9/95 (new feature) Implemented file APIs for access to low level files sl@0: on each system. The APIs are: Tcl_CloseFile, Tcl_OpenFile, Tcl_ReadFile, sl@0: Tcl_WriteFile and Tcl_SeekFile. Also implemented Tcl_WaitPid which waits sl@0: in a system dependent manner for a child process. (JL) sl@0: sl@0: 11/9/95 (new feature) Added Tcl_UpdateLinkedVar procedure to force a sl@0: Tcl variable to be updated after its C variable changes. (JO) sl@0: sl@0: 11/9/95 (bug fix) The glob command has been totally reimplemented so sl@0: that it can support different file name conventions. It now handles sl@0: Windows file names (both UNC and drive-relative) properly. It also sl@0: supports nested braces correctly now. (SS) sl@0: sl@0: 11/13/95 (bug fix) Fixed Makefile.in so that configure can be run sl@0: from a clean directory separate from the Tcl source tree, and compilations sl@0: can be performed there. (JO) sl@0: sl@0: 11/14/95 (bug fix) Fixed file sharing between interpreters and file sl@0: transferring between interpreters to correctly manage the refcount so that sl@0: files are closed when the last reference to them is discarded. (JL) sl@0: sl@0: 11/14/95 (bug fix) Fixed gettimeofday implementation for the sl@0: Macintosh. This fixes several timing related bugs. (RJ) sl@0: sl@0: 11/17/95 (new feature) Added missing support for info nameofexecutable sl@0: on the Macintosh. (RJ) sl@0: sl@0: 11/17/95 (bug fix) The Tcl variables argc argv and argv0 now return sl@0: something reasonable on the Mac. (RJ) sl@0: sl@0: 11/22/95 (new feature) Implemented "auto-detect" mode for end of line sl@0: translations. On input, standalone "\r" mean MAC mode, standalone "\n" sl@0: mean Unix mode and "\r\n" means Windows mode. On output, the mode is sl@0: modified to whatever the platform specific mode for that platform is. (JL) sl@0: sl@0: 11/24/95 (feature change) Replaced "configInfo" file with tclConfig.sh, sl@0: which is more complete and uses slightly different names. Also sl@0: arranged for tclConfig.sh to be installed in the platform-specific sl@0: library directory instead of Tcl's script library directory. (JO) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 7.5a2, but not with Tcl 7.4 *** sl@0: sl@0: ----------------- Released patch 7.4p3, 11/28/95 ----------------------- sl@0: sl@0: 12/5/95 (new feature) Added Tcl_File facility to support platform- sl@0: independent file handles. Changed all interfaces that used Unix- sl@0: style integer fd's to use Tcl_File's instead. (SS) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 12/5/95 (new feature) Added a new "clock" command to Tcl. The command sl@0: allows you to get the current "clicks" or seconds & allows you to sl@0: format or scan human readable time/date strings. (RJ) sl@0: sl@0: 12/18/95 (new feature) Moved Tk_Preserve, Tk_Release, and Tk_EventuallyFree sl@0: to Tcl, renamed to Tcl_Preserve, Tcl_Release, and Tcl_EventuallyFree. (JO) sl@0: sl@0: 12/18/95 (new feature) Added new "package" command and associated sl@0: procedures Tcl_PkgRequire and Tcl_PkgProvide. Also wrote sl@0: pkg_mkIndex library procedure to create index files from binaries sl@0: and scripts. (JO) sl@0: sl@0: 12/20/95 (new feature) Added Tcl_WaitForFile procedure. (JO) sl@0: sl@0: 12/21/95 (new features) Made package name argument to "load" optional sl@0: (Tcl will now attempt to guess the package name if necessary). Also sl@0: added Tcl_StaticPackage and support in "load" for statically linked sl@0: packages. (JO) sl@0: sl@0: 12/22/95 (new feature) Upgraded the foreach command to accept multiple sl@0: loop variables and multiple value lists. This lets you iterate over sl@0: multiple lists in parallel, and/or assign multiple loop variables from sl@0: one value list during each iteration. The only potential compatibility sl@0: problem is with scripts that used loop variables with a name that could be sl@0: construed to be a list of variable names (i.e. contained spaces). (BW) sl@0: sl@0: 1/5/96 (new feature) Changed tclsh so it builds as a console mode sl@0: application under Windows. Now tclsh can be used from the command sl@0: line with pipes or interactively. Note that this only works under sl@0: Windows 95 or NT. (SS) sl@0: sl@0: 1/17/96 (new feature) Modified Makefile and configure script to allow sl@0: Tcl to be compiled as a shared library: use the --enable-shared option sl@0: when configuing. (JO) sl@0: sl@0: 1/17/96 (removed obsolete features) Removed the procedures Tcl_EnterFile sl@0: and Tcl_GetOpenFile: these no longer make sense with the new I/O system. (JL) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 1/19/96 (bug fixes) Prevented formation of circular aliases, through the sl@0: Tcl 'interp alias' command and through the 'rename' command, as well as sl@0: through the C API Tcl_CreateAlias. (JL) sl@0: sl@0: 1/19/96 (bug fixes) Fixed several bugs in direct deletion of interpreters sl@0: with Tcl_DeleteInterp when the interpreter is a slave; fixes based on a sl@0: patch received from Viktor Dukhovni of ESM. (JL) sl@0: sl@0: 1/19/96 (new feature) Implemented on-close handlers for channels; added sl@0: the C APIs Tcl_CreateCloseHandler and Tcl_DeleteCloseHandler. (JL) sl@0: sl@0: 1/19/96 (new feature) Implemented portable error reporting mechanism; added sl@0: the C APIs Tcl_SetErrno and Tcl_GetErrno. (JL) sl@0: sl@0: 1/24/96 (bug fix) Unknown command processing properly invokes external sl@0: commands under Windows NT and Windows '95 now. (SS) sl@0: sl@0: 1/23/96 (bug fix) Eliminated extremely long startup times under Windows '95. sl@0: The problem was a result of the option database initialization code that sl@0: concatenated $HOME with /.Xdefaults, resulting in a // in the middle of the sl@0: file name. Under Windows '95, this is incorrectly interpreted as a UNC sl@0: path. They delays came from the network timeouts needed to determine that sl@0: the file name was invalid. Tcl_TranslateFileName now suppresses duplicate sl@0: slashes that aren't at the beginning of the file name. (SS) sl@0: sl@0: 1/25/96 (bug fix) Changed exec and open to create children so they are sl@0: attached to the application's console if it exists. (SS) sl@0: sl@0: 1/31/96 (bug fix) Fixed command line parsing to handle embedded sl@0: spaces under Windows. (SS) sl@0: sl@0: ----------------- Released 7.5b1, 2/1/96 ----------------------- sl@0: sl@0: 2/7/96 (bug fix) Fixed off by one error in argument parsing code under sl@0: Windows. (SS) sl@0: sl@0: 2/7/96 (bug fix) Fixed bugs in VC++ makefile that improperly sl@0: initialized the tcl75.dll. Fixed bugs in Borland makefile that caused sl@0: build failures under Windows NT. (SS) sl@0: sl@0: 2/9/96 (bug fix) Fixed deadlock problem in AUTO end of line translation sl@0: mode which would cause a socket server with several concurrent clients sl@0: writing in CRLF mode to hang. (JL) sl@0: sl@0: 2/9/96 (API change) Replaced -linemode option to fconfigure with a sl@0: new -buffering option, added "none" setting to enable immediate write. (JL) sl@0: *** INCOMPATIBILITY with b1 *** sl@0: sl@0: 2/9/96 (new feature) Added C API Tcl_InputBuffered which returns the count sl@0: of bytes currently buffered in the input buffer of a channel, and o for sl@0: output only channels. (JL) sl@0: sl@0: 2/9/96 (new feature) Implemented asynchronous connect for sockets. (JL) sl@0: sl@0: 2/9/96 (new feature) Added C API Tcl_SetDefaultTranslation to set (per sl@0: channel) the default end of line translation mode. This is the mode that sl@0: will be installed if an output operation is done on the channel while it is sl@0: still in AUTO mode. (JL) sl@0: sl@0: 2/9/96 (bug fix) Changed Tcl_OpenCommandChannel interface to properly sl@0: handle all of the combinations of stdio inheritance in background sl@0: pipelines. See the Tcl_OpenFileChannel(3) man page for more sl@0: info. This change fixes the bug where exec of a background pipeline sl@0: was not getting passed the stdio handles properly. (SS) sl@0: sl@0: 2/9/96 (bug fix) Removed the new Tcl_CreatePipeline interface, and sl@0: restored the old version for Unix platforms only. All new code should sl@0: use Tcl_CreateCommandChannel instead. (SS) sl@0: sl@0: 2/9/96 (bug fix) Changed Makefile.in to use -L and -ltcl7.5 for Tcl sl@0: library so that shared libraries are more likely to be found correctly sl@0: on more platforms. (JO) sl@0: sl@0: 2/13/96 (new feature) Added C API Tcl_SetNotifierData and sl@0: Tcl_GetNotifierData to allow notifier and channel driver writers to sl@0: associate data with a Tcl_File. The result of this change is that sl@0: Tcl_GetFileInfo now always returns an OS file handle, and Tcl_GetFile sl@0: can be used to construct a Tcl_File for an externally constructed OS sl@0: handle. (SS) sl@0: sl@0: 2/13/96 (bug fix) Changed Windows socket implementation so it doesn't sl@0: set SO_REUSEADDR on server sockets. Now attempts to create a server sl@0: socket on a port that is already in use will be properly identified sl@0: and an error will be generated. (SS) sl@0: sl@0: 2/13/96 (bug fix) Fixed problems with DLL initialization under Visual sl@0: C++ that left the C run time library uninitialized. (SS) sl@0: sl@0: 2/13/96 (bug fix) Fixed Windows socket initialization so it loads sl@0: winsock the first time it is used, rather than at the time tcl75.dll sl@0: is loaded. This should fix the bug where the modem immediately starts sl@0: trying to connect to a service provider when wish or tclsh are sl@0: started. (SS) sl@0: sl@0: 2/13/96 (new feature) Added C APIs Tcl_MakeFileChannel and sl@0: Tcl_MakeTcpClientChannel to wrap up existing fds and sockets into sl@0: channels. Provided implementations on Unix and Windows. (JL) sl@0: sl@0: 2/13/96 (bug fix) Fixed bug with seek leaving EOF and BLOCKING set. (JL) sl@0: sl@0: 2/14/96 (bug fix) Fixed reentrancy problem in fileevent handling sl@0: and made it more robust in the face of errors. (JL) sl@0: sl@0: 2/14/96 (feature change) Made generic IO level emulate blocking mode if the sl@0: channel driver is unable to provide it, e.g. if the low level device is sl@0: always nonblocking. Thus, now blocking behavior is an advisory setting for sl@0: channel drivers and can be ignored safely if the channel driver is unable sl@0: to provide it. (JL) sl@0: sl@0: 2/15/96 (new feature) Added "binary" end of line translation mode, which is sl@0: a synonym of "lf" mode. (JL) sl@0: sl@0: 2/15/96 (bug fix) Fixed reentrancy problem in fileevent handling vs sl@0: deletion of channel event handlers. (JL) sl@0: sl@0: 2/15/96 (bug fix) Fixed bug in event handling which would cause a sl@0: nonblocking channel to not see further readable events after the first sl@0: readable event that had insufficient input. (JL) sl@0: sl@0: 2/17/96 (bug fix) "info complete" didn't properly handle comments sl@0: in nested commands. (JO) sl@0: sl@0: 2/21/96 (bug fix) "exec" under Windows NT/95 did not properly handle sl@0: very long command lines (>200 chars). (SS) sl@0: sl@0: 2/21/96 (bug fix) Sockets could get into an infinite loop if a read sl@0: event arrived after all of the available data had been read. (SS) sl@0: sl@0: 2/22/96 (bug fix) Added cast of st_size elements to (long) before sl@0: sprintf-ing in "file size" command. This is needed to handle systems sl@0: like NetBSD with 64-bit file offsets. (JO) sl@0: sl@0: ----------------- Released 7.5b2, 2/23/96 ----------------------- sl@0: sl@0: 2/23/96 (bug fix) TCL_VARARGS macro in tcl.h wasn't defined properly sl@0: when compiling with C++. (JO) sl@0: sl@0: 2/24/96 (bug fix) Removed dependencies on Makefile in the UNIX Makefile: sl@0: this caused problems on some platforms (like Linux?). (JO) sl@0: sl@0: 2/24/96 (bug fix) Fixed configuration bug that made Tcl not compile sl@0: correctly on Linux machines with neither -ldl or -ldld. (JO) sl@0: sl@0: 2/24/96 (new feature) Added a block of comments and definitions to sl@0: Makefile.in to make it easier to have Tcl's TclSetEnv etc. replace sl@0: the library procedures setenv etc, so that calls to setenv etc. in sl@0: the application automatically update the Tcl "env" variable. (JO) sl@0: sl@0: 2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL) sl@0: to C API Tcl_Close and simplified closing of command channels. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *** sl@0: sl@0: 2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL) sl@0: to C type definition Tcl_DriverCloseProc; modified all channel drivers to sl@0: implement close procedures that accept the additional argument. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *** sl@0: sl@0: 2/28/96 (bug fix) Fixed memory leak that could occur if an upvar sl@0: referred to an element of an array in the same stack frame as the sl@0: upvar. (JO) sl@0: sl@0: 2/29/96 (feature change) Modified both Tcl_DoOneEvent and Tcl_WaitForEvent sl@0: so that they return immediately in cases where they would otherwise sl@0: block forever (e.g. if there are no event handlers of any sort). (JO) sl@0: sl@0: 2/29/96 (new feature) Added C APIs Tcl_GetChannelBufferSize and sl@0: Tcl_SetChannelBufferSize to set and retrieve the size, in bytes, for sl@0: buffers allocated to store input or output in a channel. (JL) sl@0: sl@0: 2/29/96 (new feature) Added option -buffersize to Tcl fconfigure command sl@0: to allow Tcl scripts to query and set the size of channel buffers. (JL) sl@0: sl@0: 2/29/96 (feature removed) Removed channel driver function to specify sl@0: the buffer size to use when allocating a buffer. Removed the C typedef sl@0: for Tcl_DriverBufferSizeProc. Channels are now created with a default sl@0: buffer size of 4K. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *** sl@0: sl@0: 2/29/96 (feature change) The channel driver function for setting blocking sl@0: mode on the device may now be NULL. If the generic code detects that the sl@0: function is NULL, operations that set the blocking mode on the channel sl@0: simply succeed. (JL) sl@0: sl@0: 3/2/96 (bug fix) Fixed core dump that could occur if a syntax error sl@0: (such as missing close paren) occurred in an array reference with a sl@0: very long array name. (JO) sl@0: sl@0: 3/4/96 (bug fix) Removed code in the "auto_load" procedure that deletes sl@0: all existing auto-load information whenever the "auto_path" variable sl@0: is changed. Instead, new information adds to what was already there. sl@0: Otherwise, changing the "auto_path" variable causes all package- sl@0: related information to be lost. If you really want to get rid of sl@0: existing auto-load information, use auto_reset before setting auto_path. (JO) sl@0: sl@0: 3/5/96 (new feature) Added version suffix to shared library names so that sl@0: Tcl will compile under NetBSD and FreeBSD (I hope). (JO) sl@0: sl@0: 3/6/96 (bug fix) Cleaned up error messages in new I/O system to correspond sl@0: more closely to old I/O system. (JO) sl@0: sl@0: 3/6/96 (new feature) Added -myaddr and -myport options to the socket sl@0: command, removed -tcp and -- options. This lets clients and servers sl@0: choose a particular interface. Also changed the default server address sl@0: from the hostname to INADDR_ANY. The server accept callback now gets sl@0: passed the client's port as well as IP address. The C interfaces for sl@0: Tcl_OpenTcpClient and Tcl_OpenTcpServer have changed to support the sl@0: above changes. (BW) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *** sl@0: sl@0: 3/6/96 (changed feature) The library function auto_mkindex will now sl@0: default to using the pattern "*.tcl" if no pattern is given. (RJ) sl@0: sl@0: 3/6/96 (bug fix) The socket channel code for the Macintosh has been sl@0: rewritten to use native MacTcp. (RJ) sl@0: sl@0: 3/7/96 (new feature) Added Tcl_SetStdChannel and Tcl_GetStdChannel sl@0: interfaces to allow applications to explicitly set and get the global sl@0: standard channels. (SS) sl@0: sl@0: 3/7/96 (bug fix) Tcl did close not the file descriptors associated sl@0: with "stdout", etc. when the corresponding channels were closed. (SS) sl@0: sl@0: 3/7/96 (bug fix) Reworked shared library and dynamic loading stuff to sl@0: try to get it working under AIX. Added new @SHLIB_LD_LIBS@ autoconf sl@0: symbol as part of this. AIX probably doesn't work yet, but it should sl@0: be a lot closer. (JO) sl@0: sl@0: 3/7/96 (feature change) Added Tcl_ChannelProc typedef and changed the sl@0: signature of Tcl_CreateChannelHandler and Tcl_DeleteChannelHandler to take sl@0: Tcl_ChannelProc arguments instead of Tcl_FileProc arguments. This change sl@0: should not affect any code outside Tcl because the signatures of sl@0: Tcl_ChannelProc and Tcl_FileProc are compatible. (JL) sl@0: sl@0: 3/7/96 (API change) Modified signature of Tcl_GetChannelOption to return sl@0: an int instead of char *, and to take a Tcl_DString * argument. Modified sl@0: the implementation so that the option name can be NULL, to mean that the sl@0: call should retrieve a list of alternating option names and values. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *** sl@0: sl@0: 3/7/96 (API change) Added Tcl_DriverSetOptionProc, Tcl_DriverGetOptionProc sl@0: typedefs, added two slots setOptionProc and getOptionProc to the channel sl@0: type structure. These may be NULL to indicate that the channel type does sl@0: not support any options. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 *** sl@0: sl@0: 3/7/96 (feature change) stdin, stdout and stderr can now be put into sl@0: nonblocking mode. (JL) sl@0: sl@0: 3/8/96 (feature change) Eliminated dependence on the registry for sl@0: finding the Tcl library files. (SS) sl@0: sl@0: ----------------- Released 7.5b3, 3/8/96 ----------------------- sl@0: sl@0: 3/12/96 (feature improvement) Modified startup script to look in several sl@0: different places for the Tcl library directory. This should allow Tcl sl@0: to find the libraries under all but the weirdest conditions, even without sl@0: the TCL_LIBRARY environment variable being set. (JO) sl@0: sl@0: 3/13/96 (bug fix) Eliminated use of the "linger" option from the Windows sl@0: socket implementation. (JL) sl@0: sl@0: 3/13/96 (new feature) Added -peername and -sockname options for fconfigure sl@0: for socket channels. Code contributed by John Haxby of HP. (JL) sl@0: sl@0: 3/13/96 (bug fix) Fixed panic and core dump that would occur if the accept sl@0: callback script on a server socket encountered an error. (JL) sl@0: sl@0: 3/13/96 (feature change) Added -async option to the Tcl socket command. sl@0: If the command is creating a client socket and the flag is present, the sl@0: client is connected asynchronously. If the option is absent (the default), sl@0: the client socket is connected synchronously, and the command returns only sl@0: when the connection has been completed or failed. This change was suggested sl@0: by Mark Diekhans. (JL) sl@0: sl@0: 3/13/96 (feature change) Modified the signature of Tcl_OpenTcpClient to sl@0: take an additional int argument, async. If nonzero, the client is connected sl@0: to the server asynchronously. If the value is zero, the connection is made sl@0: synchronously, and the call to Tcl_OpenTcpClient returns only when the sl@0: connection fails or succeeds. This change was suggested by Mark Diekhans. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *** sl@0: sl@0: 3/14/96 (bug fix) "tclsh bogus_file_name" didn't print an error message. (JO) sl@0: sl@0: 3/14/96 (bug fix) Added new procedures to tclCkalloc.c so that libraries sl@0: and applications can be compiled with TCL_MEM_DEBUG even if Tcl isn't sl@0: (however, the converse is still not true). Patches provided by Jan sl@0: Nijtmans. (JO) sl@0: sl@0: 3/15/96 (bug fix) Marked standard IO handles of a process as close-on-exec sl@0: to fix bug in Ultrix where exec was not sharing standard IO handles with sl@0: subprocesses. Fix suggested by Mark Diekhans. (JL) sl@0: sl@0: 3/15/96 (bug fix) Fixed asynchronous close mechanism so that it closes the sl@0: channel instead of leaking system resources. The manifestation was that Tcl sl@0: would eventually run out of file descriptors if it was handling a large sl@0: number of nonblocking sockets or pipes with high congestion. (JL) sl@0: sl@0: 3/15/96 (bug fix) Fixed tests so that they no longer leak file descriptors. sl@0: The manifestation was that Tcl would eventually run out of file descriptors sl@0: if the tests were rerun many times (> a hundred times on Solaris). (JL) sl@0: sl@0: 3/15/96 (bug fix) Fixed channel creation code so that it never creates sl@0: unnamed channels. This would cause a panic and core dump when the channel sl@0: was closed. (JL) sl@0: sl@0: 3/16/96 (bug fixes) Made lots of changes in configuration stuff to get sl@0: Tcl working under AIX (finally). Tcl should now support the "load" sl@0: command under AIX and should work either with or without shared sl@0: libraries for Tcl and Tk. (JO) sl@0: sl@0: 3/21/96 (configuration improvement) Changed configure script so it sl@0: doesn't use version numbers (as in -ltcl7.5 and libtcl7.5.so) under sl@0: SunOS 4.1, where they don't work anyway. (JO) sl@0: sl@0: 3/22/96 (new feature) Added C API Tcl_InterpDeleted that allows extension sl@0: writers to discover when an interpreter is being deleted. (JL) sl@0: sl@0: 3/22/96 (bug fix) The standard IO channels are now added to each sl@0: trusted interpreter as soon as the interpreter is created. This ensures sl@0: against the bug where a child would do IO before the master had done any, sl@0: and then the child is destroyed - the standard IO channels would be then sl@0: closed and the master would be unable to do any IO. (JL) sl@0: sl@0: 3/22/96 (bug fix) Made Tcl more robust against interpreter deletion, by sl@0: using Tcl_Preserve, Tcl_Release and Tcl_EventuallyFree to split the process sl@0: of interpreter deletion into two distinct phases. Also went through all of sl@0: Tcl and added calls to Tcl_Preserve and Tcl_Delete where needed. (JL) sl@0: sl@0: 3/22/96 (bug fix) Fixed several places where C code was reading and writing sl@0: into freed memory, especially during interpreter deletion. (JL) sl@0: sl@0: 3/22/96 (bug fix) Fixed very deep bug in Tcl_Release that caused memory to sl@0: be freed twice if the release callback did Tcl_Preserve and Tcl_Release on sl@0: the same memory as the chunk currently being freed. (JL) sl@0: sl@0: 3/22/96 (bug fix) Removed several memory leaks that would cause memory sl@0: buildup on half-K chunks in the generic IO level. (JL) sl@0: sl@0: 3/22/96 (bug fix) Fixed several core dumps which occurred when new sl@0: AssocData was being created during the cleanups in interpreter deletion. sl@0: The solution implemented now is to loop repeatedly over the AssocData until sl@0: none is left to clean up. (JL) sl@0: sl@0: 3/22/96 (bug fix) Fixed a bug in event handling which caused an infinite sl@0: loop if there were no files being watched and no timer. Fix suggested by sl@0: Jan Nijtmans. (JL) sl@0: sl@0: 3/22/96 (bug fix) Fixed Tcl_CreateCommand, Tcl_DeleteCommand to be more sl@0: robust if the interpreter is being deleted. Also fixed several order sl@0: dependency bugs in Tcl_DeleteCommand which kicked in when an interpreter sl@0: was being deleted. (JL) sl@0: sl@0: 3/26/96 (bug fix) Upon a "short read", the generic code no longer calls sl@0: the driver for more input. Doing this caused blocking on some platforms sl@0: even on nonblocking channels. Bug and fix courtesy Mark Roseman. (JL) sl@0: sl@0: 3/26/96 (new feature) Added 'package Tcltest' which is present only in sl@0: test versions of Tcl; this allows the testing commands to be loaded into sl@0: new interpreters besides the main one. (JL) sl@0: sl@0: 3/26/96 (restored feature) Recreated the Tcl_GetOpenFile C API. You can sl@0: now get a FILE * from a registered channel; Unix only. (JL) sl@0: sl@0: 3/27/96 (bug fix) The regular expression code did not support more sl@0: than 9 subexpressions. It now supports up to 20. (SS) sl@0: sl@0: 4/1/96 (bug fixes) The CHANNEL_BLOCKED bit was being left on on a short sl@0: read, so that fileevents wouldn't fire correctly. Bug reported by Mark sl@0: Roseman.(JL, RJ) sl@0: sl@0: 4/1/96 (bug fix) Moved Tcl_Release to match Tcl_Preserve exactly, in sl@0: tclInterp.c; previously interpreters were being freed only conditionally sl@0: and sometimes not at all. (JL) sl@0: sl@0: 4/1/96 (bug fix) Fixed error reporting in slave interpreters when the sl@0: error message was being generated directly by C code. Fix suggested by sl@0: Viktor Dukhovni of ESM. (JL) sl@0: sl@0: 4/2/96 (bug fixes) Fixed a series of bugs in Windows sockets that caused sl@0: events to variously get lost, to get sent multiple times, or to be ignored sl@0: by the driver. The manifestation was blocking if the channel is blocking, sl@0: and either getting EAGAIN or infinite loops if the channel is nonblocking. sl@0: This series of bugs was found by Ian Wallis of Cisco. Now all tests (also sl@0: those that were previously commented out) in socket.test pass. (JL, SS) sl@0: sl@0: 4/2/96 (feature change/bug fix) Eliminated network name support in sl@0: favor of better native name support. Added "file split", "file join", sl@0: and "file pathtype" commands. See the "file" man page for more sl@0: details. (SS) sl@0: *** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *** sl@0: sl@0: 4/2/96 (bug fix) Changed implementation of auto_mkindex so tclIndex sl@0: files will properly handle path names in a cross platform context. (SS) sl@0: sl@0: 4/5/96 (bug fix) Fixed Tcl_ReadCmd to use the channel buffer size as the sl@0: chunk size it reads, instead of a fixed 4K size. Thus, on large reads, the sl@0: user can set the channel buffer size to a large size and the read will sl@0: occur orders of magnitude faster. For example, on a 2MB file, reading in 4K sl@0: chunks took 34 seconds, while reading in 1MB chunks took 1.5 seconds (on a sl@0: SS-20). Problem identified and fix suggested by John Haxby of HP. (JL) sl@0: sl@0: 4/5/96 (bug fix) Fixed socket creation code to invoke gethostbyname only if sl@0: inet_addr failed (very unlikely). Before this change the order was reversed sl@0: and this made things much slower than they needed to be (gethostbyname sl@0: generally requires an RPC, which is slow). Problem identified and fix sl@0: suggested by John Loverso of OSF. (JL) sl@0: sl@0: 4/9/96 (feature change) Modified "auto" translation mode so that it sl@0: recognizes any of "\n", "\r" and "\r\n" in input as end of line, so sl@0: that a file can have mixed end-of-line sequences. It now outputs sl@0: the platform specific end of line sequence on each platform for files and sl@0: pipes, and for sockets it produces crlf in output on all platforms. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *** sl@0: sl@0: 4/11/96 (new feature) Added -eofchar option to Tcl_SetChannelOption to allow sl@0: setting of an end of file character for input and output. If an input eof sl@0: char is set, it is recognized as EOF and further input from the channel is sl@0: not presented to the caller. If an output eof char is set, on output, that sl@0: byte is appended to the channel when it is closed. On Unix and Macintosh, sl@0: all channels start with no eof char set for input or output. On Windows, sl@0: files and pipes start with input and output eof chars set to Crlt-Z (ascii sl@0: 26), and sockets start with no input or output eof char. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 *** sl@0: sl@0: 4/17/96 (bug fix) Fixed series of bugs with handling of crlf sequence split sl@0: across buffer boundaries in input, in AUTO mode. (JL, BW) sl@0: sl@0: 4/17/96 (test suite improvement) Fixed test suite so that tests that sl@0: depend on the availability of Unix commands such as echo, cat and others sl@0: are not run if these commands are not present. (JL) sl@0: sl@0: 4/17/96 (test suite improvement) The socket test now automatically starts, sl@0: on platformst that support exec, a separate process for remote testsing. (JL) sl@0: sl@0: ----------------- Released 7.5, 4/21/96 ----------------------- sl@0: sl@0: 5/1/96 (bug fix) "file tail ~" did not correctly return the tail sl@0: portion of the user's home directory. (SS) sl@0: sl@0: 5/1/96 (bug fix) Fixed bug in TclGetEnv where it didn't lookup environment sl@0: variables correctly: could confuse "H" and "HOME", for example. (JO) sl@0: sl@0: 5/1/96 (bug fix) Changed to install tclConfig.sh under "make install-binaries", sl@0: not "make install-libraries". (JO) sl@0: sl@0: 5/2/96 (bug fix) Changed pkg_mkIndex not to attempt to "load" a file unless sl@0: it has the standard shared library extension. On SunOS, attempts to load sl@0: Tcl scripts cause the whole application to be aborted (there's no way to sl@0: get the error back into Tcl). (JO) sl@0: sl@0: 5/7/96 (bug fix) Moved initScript in tclUnixInit.c to writable memory to sl@0: avoid potential core dumps. (JO) sl@0: sl@0: 5/7/96 (bug fix) Auto_reset procedure was removing procedure from init.tcl, sl@0: such as pkg_mkIndex. (JO) sl@0: sl@0: 5/7/96 (bug fix) Fixed cast on socket address resolution code that sl@0: would cause a failure to connect on Dec Alphas. (JL) sl@0: sl@0: 5/7/96 (bug fix) Added "time", "subst" and "fileevent" commands to set of sl@0: commands available in a safe interpreter. (JL) sl@0: sl@0: 5/13/96 (bug fix) Preventing OS level handles for stdin, stdout and stderr sl@0: from being implicitly closed when the last reference to the standard sl@0: channel containing that handle is discarded when an interpreter is deleted. sl@0: Explicitly closing standard channels by using "close" still works. (JL) sl@0: sl@0: 5/21/96 (bug fix) Do not create channels for stdin, stdout and stderr on sl@0: Unix if the devices are closed. This prevents a duplicate channel name sl@0: panic later on when the fd is used to open a channel and the channel is sl@0: registered in an interpreter. (JL) sl@0: sl@0: 5/23/96 (bug fix) Fixed bug that prevented the use of standard channels in sl@0: interpreters created after the last interpreter was destroyed. In the sequence sl@0: sl@0: interp = Tcl_CreateInterp(); sl@0: Tcl_DeleteInterp(interp); sl@0: interp = Tcl_CreateInterp(); sl@0: sl@0: channels for stdio would not be available in the second interpreter. (JL) sl@0: sl@0: 5/23/96 (bug fix) Fixed bug that allowed Tcl_MakeFileChannel to create new sl@0: channels with Tcl_Files in them that are already used by another channel. sl@0: This would cause core dumps when the Tcl_Files were being freed twice. (JL) sl@0: sl@0: 5/23/96 (bug fix) Fixed a logical timing bug that caused a standard channel sl@0: to be removed from the standard channel table too early when the channel sl@0: was being closed. If the channel was being flushed asynchronously, it could sl@0: get recreated before being actually destroyed, and the recreated channel sl@0: would contain the same Tcl_File as the one being closed, leading to sl@0: dangling pointers and core dumps. (JL) sl@0: sl@0: 5/27/96 (bug fix) Fixed a bug in Tcl_GetChannelOption which caused it to sl@0: always return a list of one element, a list of the settings, for sl@0: -translation and -eofchar options. Now correctly returns the value sl@0: described by the documentation (Mark Diekhans found this, thanks!). (JL) sl@0: sl@0: 5/30/96 (bug fix) Fixed a couple of syntax errors in io.test. (JL) sl@0: sl@0: 5/30/96 (bug fix) If a fileevent scripts gets an error, delete it before sl@0: causing a background error. This is to allow the error handler to reinstall sl@0: the fileevent and to prevent infinite loops if the event loop is reentered sl@0: in the error handler. (JL) sl@0: sl@0: 5/31/96 (bug fix) Channels now will get properly flushed on exit. (JL) sl@0: sl@0: 6/5/96 (bug fix) Changed Tcl_Ckalloc, Tcl_Ckfree, and Tcl_Ckrealloc to sl@0: Tcl_Alloc, Tcl_Free, and Tcl_Realloc. Added documentation for these sl@0: routines now that they are officially supported. Extension writers sl@0: should use these routines instead of free() and malloc(). (SS) sl@0: sl@0: 6/10/96 (bug fix) Changes the Tcl close command so that it no longer sl@0: waits on nonblocking pipes for the piped processes to exit; instead it sl@0: reaps them in the background. (JL) sl@0: sl@0: 6/11/96 (bug fix) Increased the length of the listen queue for server sl@0: sockets on Unix from 5 to 100. Some OSes will disregard this and reset it sl@0: to 5, but we should try to get as long a queue as we can, for performance sl@0: reasons. (JL) sl@0: sl@0: 6/11/96 (bug fix) Fixed windows sockets bug that caused a cascade of events sl@0: if the fileevent script read less than was available. Now reading less than sl@0: is available does not cause a flood of Tcl events. (JL, SS) sl@0: sl@0: 6/11/96 (bug fix) Fixed bug in background flushing on closed channels that sl@0: would prevent the last buffer from getting flushed. (JL) sl@0: sl@0: 6/13/96 (bug fix) Fixed bug in Windows sockets that caused a core dump if sl@0: a DLL linked with tcl.dll and referred to e.g. ntohs() without opening a sl@0: Tcl socket. The problem was that the indirection table was not being sl@0: initialized. (JL) sl@0: sl@0: 6/13/96 (bug fix) Fixed OS level resource leak that would occur when a sl@0: Tcl channel was still registered in some interpreter when the process sl@0: exits. Previously the channel was not being closed and the OS level handles sl@0: were not being released; the output was being flushed but the device was sl@0: not being closed. Now the device is properly closed. This was only a sl@0: problem on Win3.1 and MacOS. (JL, SS) sl@0: sl@0: 6/28/96 (bug fix) Fixed bug where transient errors were leaving an error sl@0: code around, so that it would erroneously get reported later. This bug was sl@0: exercised intermittently by closing a channel to a file on a very loaded sl@0: NFS server, or to a socket whose other end blocked. (JL, BW) sl@0: sl@0: 7/3/96 (bug fix) Fileevents declared in an interpreter are now deleted sl@0: when the channel is closed in that interpreter. Before this fix, the sl@0: fileevent would hang around until the channel is completely closed, and sl@0: would cause errors if events happened before the channel was closed. This sl@0: could happen in two cases: first if the channel is shared between several sl@0: interpreters, and second if an async flush is in progress that prevents the sl@0: channel from being closed until the flush finishes. (JL) sl@0: sl@0: 7/10/96 (bug fix) Fixed bugs in both "lrange" and "lreplace" commands sl@0: where too much white space was being removed. For example, the command sl@0: lreplace {\}\ hello} end end sl@0: was returning "\}\", losing the significant space in the first list sl@0: element and corrupting the list. (JO) sl@0: sl@0: 7/20/96 (bug fix) The procedure pkg_mkIndex didn't work properly for sl@0: extensions that depend on Tk, because it didn't load Tk into the child sl@0: interpreter before loading the extension. Now it loads Tk if Tk is sl@0: present in the parent. (JO) sl@0: sl@0: 7/23/96 (bug fix) Added compat version of strftime to fix crashes sl@0: resulting from bad implementations under Windows. (SS) sl@0: sl@0: 7/23/96 (bug fix) Standard implementations of gmtime() and localtime() sl@0: under Windows did not handle dates before 1970, so they were replaced sl@0: with a revised implementation. (SS) sl@0: sl@0: 7/23/96 (bug fix) Tcl would crash on exit under Borland 5.0 because sl@0: the global environ pointer was left pointing to freed memory. (SS) sl@0: sl@0: 7/29/96 (bug fix) Fixed memory leak in Tcl_LoadCmd that could occur if sl@0: a package's AppInit procedure called Tcl_StaticPackage to register sl@0: static packages. (JO) sl@0: sl@0: 8/1/96 (bug fix) Fixed a series of bugs in Windows sockets so that async sl@0: writebehind in the presence of read event handlers now works, and so that sl@0: async writebehind also works on sockets for which a read event handler was sl@0: declared and whose channels were then closed before the async write sl@0: finished. The bug was reported by John Loverso and Steven Wahl, sl@0: independently, test case supplied by John Loverso. (JL) sl@0: sl@0: ----------------- Released patch 7.5p1, 8/2/96 ----------------------- sl@0: sl@0: 5/8/96 (new feature) Added Tcl_GetChannelMode C API for retrieving whether sl@0: a channel is open for reading and writing. (JL) sl@0: sl@0: 5/8/96 (API changes) Revised C APIs for channel drivers: sl@0: - Removed all Tcl_Files from channel driver interface; you can now have sl@0: channels that are not based on Tcl_Files. sl@0: - Added channelReadyProc and watchChannelProc procedures to interface; sl@0: these are used to implement event notification for channels. sl@0: - Added getFileProc to channel driver, to allow the generic IO code sl@0: to retrieve a Tcl_File from a channel (presumably if the channel sl@0: uses Tcl_Files they will be stored inside its instanceData). (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5 *** sl@0: sl@0: 5/8/96 (API change) The Tcl_CreateChannel C API was modified to not take sl@0: Tcl_File arguments, and instead to take a mask specifying whether the sl@0: channel is readable and/or writable. (JL) sl@0: *** INCOMPATIBILITY with Tcl 7.5 *** sl@0: sl@0: 6/3/96 (bug fix) Made Tcl_SetVar2 robust against the case where the value sl@0: of the variable is a NULL pointer instead of "". (JL) sl@0: sl@0: 6/17/96 (bug fix) Fixed "reading uninitialized memory" error reported by sl@0: Purify, in Tcl_Preserve/Tcl_Release. (JL) sl@0: sl@0: 8/9/96 (bug fix) Fixed bug in init.tcl that caused incorrect error message sl@0: if the act of autoloading a procedure caused the procedure to be invoked sl@0: again. (JO) sl@0: sl@0: 8/9/96 (bug fix) Configure script produced bad library names and extensions sl@0: under SunOS and a few other platforms if the --disable-load switch was used. sl@0: (JO) sl@0: sl@0: 8/9/96 (bug fix) Tcl_UpdateLinkedVar generated an error if the variable sl@0: being updated was read-only. (JO) sl@0: sl@0: 8/14/96 (bug fix) The macintosh now supports synchronous socket sl@0: connections. Other minor bugs were also fixed. (RJ) sl@0: sl@0: 8/15/96 (configuration improvement) Changed the file patchlevel.h sl@0: to be tclPatch.h. This avoids conflict with the Tk file and is now sl@0: in 8.3 format on the Windows platform. (RJ) sl@0: sl@0: 8/20/96 (bug fix) Fixed core dump in interp alias command for interpreters sl@0: created with Tcl_CreateInterp (as opposed to with Tcl_CreateSlave). (JL) sl@0: sl@0: 8/20/96 (bug fix) No longer masking ECONNRESET on Windows sockets so sl@0: that the higher level of the IO mechanism sees the error instead of sl@0: entering an infinite loop. (JL) sl@0: sl@0: 8/20/96 (bug fix) Destroying the last interpreter no longer closes the sl@0: standard channels. (JL) sl@0: sl@0: 8/20/96 (bug fix) Closing one of the stdin, stdout or stderr channels and sl@0: then opening a new channel now correctly assigns the new channel as the sl@0: standard channel that was closed. (JL) sl@0: sl@0: 8/20/96 (bug fix) Added code to unix/tclUnixChan.c for using ioctl with sl@0: FIONBIO instead of fcntl with O_NONBLOCK, for those versions of Unix where sl@0: either O_NONBLOCK is not supported or implemented incorrectly. (JL) sl@0: sl@0: 8/21/96 (bug fix) Fixed "file extension" so it correctly returns the sl@0: extension on files like "foo..c" as "..c" instead of ".c". (SS) sl@0: sl@0: 8/22/96 (bug fix) If environ[] contains static strings, Tcl would core sl@0: dump in TclSetupEnv because it was trying to write NULLs into the actual sl@0: data in environ[]. Now we instead copy as appropriate. (JL) sl@0: sl@0: 8/22/96 (added impl) Added missing implementation of Tcl_MakeTcpClientChannel sl@0: for Windows platform. Code contributed by Mark Diekhans. (JL) sl@0: sl@0: 8/22/96 (new feature) Added a new memory allocator for the Macintosh sl@0: version of Tcl. It's quite a bit faster than MetroWerk's version. (RJ) sl@0: sl@0: 8/26/96 (documentation update) Removed old change bars (for all changes sl@0: in Tcl 7.5 and earlier releases) from manual entries. (JO) sl@0: sl@0: 8/27/96 (enhancement) The exec and open commands behave better and work in sl@0: more situations under Windows NT and Windows 95. Documentation describes sl@0: what is still lacking. (CS) sl@0: sl@0: 8/27/96 (enhancement) The Windows makefiles will now compile even if the sl@0: compiler is not in the path and/or the compiler's environment variables sl@0: have not been set up. (CS) sl@0: sl@0: 8/27/96 (configuration improvement) The Windows resource files are sl@0: automatically updated when the version/patch level changes. The header file sl@0: now has a comment that reminds the user which other files must be manually sl@0: updated when the version/patch level changes. (CS) sl@0: sl@0: 8/28/96 (new feature) Added file manipulation features (copy, rename, delete, sl@0: mkdir) that are supported on all platforms. They are implemented as sl@0: subcommands to the "file" command. See the documentation for the "file" sl@0: command for more information. (JH) sl@0: sl@0: ----------------- Released 7.6b1, 8/30/96 ----------------------- sl@0: sl@0: 9/3/96 (bug fix) Simplified code so that standard channels are created sl@0: lazily, they are added to an interpreter lazily, and they are never added sl@0: to a safe interpreter. (JL) sl@0: sl@0: 9/3/96 (bug fix) Closing a channel after closing a standard channel, e.g. sl@0: stdout, would cause the implicit recreation of that standard channel. (JL) sl@0: sl@0: 9/3/96 (new feature) Now calling Tcl_RegisterChannel with a NULL sl@0: interpreter increments the refcount so that code outside any interpreter sl@0: can use channels that are also registered in interpreters, without worrying sl@0: that the channel may turn into a dangling pointer at any time. Calling sl@0: Tcl_UnregisterChannel with a NULL interpreter only decrements the recount sl@0: so that code outside any interpreter can safely declare it is no longer sl@0: interested in a channel. (JL) sl@0: sl@0: 9/4/96 (new features) Two changes to dynamic loading: sl@0: - If the file name is empty in the "load" command and there is no sl@0: statically loaded version of the package, a dynamically loaded sl@0: version will be used if there is one. sl@0: - Tcl_StaticPackage ignores redundant calls for the same package. (JO) sl@0: sl@0: 9/6/96 (bug fix) Platform specific procedures for manipulating files are sl@0: no longer macros and have been prefixed with "Tclp", such as TclpRenameFile. sl@0: Unix file code now handles symbolic links and other special files correctly. sl@0: The semantics of file copy and file rename has been changed so that if sl@0: a target directory exists, the source files will NOT be merged with the sl@0: existing files. (JH) sl@0: sl@0: 9/6/96 (bug fix) If standard channel is NULL, because Tcl cannot connect sl@0: to the standard channel, do not increment the refcount. The channel can sl@0: be NULL if there is for example no standard input. (JL) sl@0: sl@0: 9/6/96 (portability improvement) Changed parsing of backslash sequences sl@0: like \n to translate directly to absolute values like 0xa instead of sl@0: letting the compiler do the translation. This guarantees that the sl@0: translation is done the same everywhere. (JO) sl@0: sl@0: 9/9/96 (bug fix) If channel is opened and not associated with any sl@0: interpreter, but Tcl decides to use it as one of the standard channels, it sl@0: became impossible to close the channel with Tcl_Close -- instead you had sl@0: to call Tcl_UnregisterChannel. Fixed now so that it's safe to call sl@0: Tcl_Close even when Tcl is using the channel as one of the standard ones. (JL) sl@0: sl@0: 9/11/96 (feature change) The Tcl library is now placed in the Tcl sl@0: shared libraries resource. You no longer need to place the Tcl files sl@0: in your applications explicitly. (RJ) sl@0: sl@0: 9/11/96 (feature change) Extensions no longer automatically have the sl@0: resource fork of the extension opened for it. Instead you need to sl@0: use the tclMacLibrary.c file in your extension. (RJ) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 9/12/96 (bug fix) The extension loading mechanism on the Macintosh now sl@0: looks at the 'cfrg' resource to determine where to load the code sl@0: fragment from. This means FAT fragments should now work. (RJ) sl@0: sl@0: 9/18/96 (enhancement) The exec and open commands behave better and work in sl@0: more situations under Windows 3.X. Documentation describes what is still sl@0: lacking. (CS) sl@0: sl@0: 9/19/96 (bug fix) Fixed a panic which would occur if you delete a sl@0: non-existent alias before any aliases are created. Now instead correctly sl@0: returns an error that the alias is not found. (JL) sl@0: sl@0: 9/19/96 (bug fix) Slave interpreters could rename aliases and they would sl@0: not get deleted when the alias was being redefined. This led to dangling sl@0: pointers etc. (JL) sl@0: sl@0: 9/19/96 (bug fix) Fixed a panic where a hash table entry was being deleted sl@0: twice during alias management operations. (JL) sl@0: sl@0: 9/19/96 (bug fix) Fixed bug in event loop that could cause the input focus sl@0: in Tk to get confused during menu traversal, among other problems. The sl@0: problem was related to handling of the "marker" when its event was sl@0: deleted. (JO) sl@0: sl@0: 9/26/96 (bug fix) Windows was losing EOF on a socket if the FD_CLOSE event sl@0: happened to precede any left over FD_READ events. Now correctly remembers sl@0: seeing FD_CLOSE, so that trailing FD_READ events are not discarded if they sl@0: do not contain any data. This allows Tcl to correctly get a zero read and sl@0: notice EOF. (JL) sl@0: sl@0: 9/26/96 (bug fix) Was not resetting READABLE state properly on sockets sl@0: under Windows if the driver discarded an FD_READ event because no data was sl@0: present. Now correctly resets the state. (JL) sl@0: sl@0: 9/30/96 (bug fix) Made EOF sticky on Windows sockets, so that fileevent sl@0: readable will fire repeatedly until the socket is closed. Previously the sl@0: fileevent fired only once. This could lead to never-closed connections if sl@0: the Tcl script in the fileevent wasn't closing the socket immediately. (JL) sl@0: sl@0: 10/2/96 (new feature) Improved the package loader: sl@0: - Added new variable tcl_pkgPath, which holds the default sl@0: directories under which packages are normally installed (each sl@0: package goes in a separate subdirectory of a directory in sl@0: $tcl_pkgPath). These directories are included in auto_path by sl@0: default. sl@0: - Changed the package auto-loader to look for pkgIndex.tcl files sl@0: not only in the auto_path directories but also in their immediate sl@0: children. This should make it easier to install and uninstall sl@0: packages (don't have to change auto_path or merge pkgIndex.tcl sl@0: files). (JO) sl@0: sl@0: 10/3/96 (bug fix) Changed tclsh to look for tclshrc.tcl instead of sl@0: tclsh.rc on startup under Windows. This is more consistent with wish and sl@0: uses the right extension. (SS) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 10/8/96 (bug fix) Convertclock does not parse 24-hour times of the sl@0: form "hhmm" correctly when hour = 00. In the parse code, hour must be sl@0: >= 100 for minutes to be non-zero. Thanks to Lint LaCour for this sl@0: bug fix. (RJ) sl@0: sl@0: 10/11/96 (bug fix) Under Windows, the pid command returned the process sl@0: handle instead of the process id. (SS) sl@0: sl@0: ----------------- Released 7.6, 10/16/96 ----------------------- sl@0: sl@0: 10/29/96 (bug fix) Under Windows, sockets would consume 100% CPU time after sl@0: the first accept(), due to a typo. (JL) sl@0: sl@0: 10/29/96 (bug fix) Incorrect refcount management caused standard channels sl@0: not to get deleted at process exit or DLL unload time, causing a memory sl@0: leak of upwards of 20K each time. (JL) sl@0: sl@0: 11/7/96 (bug fix) Auto-exec didn't work on file names that contained sl@0: spaces. (JO) sl@0: sl@0: 11/8/96 (bug fix) Fixed core dump that would occur if more than one call sl@0: to Tcl_DeleteChannelHandler was made to delete a given channel handler. (JL) sl@0: sl@0: 11/8/96 (bug fix) Fixed test for return value in Tcl_Seek and Tcl_SeekCmd sl@0: to only treat -1 as error, instead of all negative numbers. (JL) sl@0: sl@0: 11/12/96 (bug fix) Do not blocking waiting for processes at the end of a sl@0: pipe during exit cleanup. (JL) sl@0: sl@0: 11/12/96 (bug fix) If we are in exit cleanup, do not close the system level sl@0: file descriptors 0, 1 and 2. Previously they were being closed which is sl@0: incorrect, in the embedded case. This led to weird behavior for programs sl@0: that want to interpose on I/O through the standard file descriptors (e.g. sl@0: Netscape Navigator). (JL) sl@0: sl@0: 11/15/96 (bug fix) Fixed core dump on Windows sockets due to dependency on sl@0: deletion order at exit. Now all socket functions check to see if sockets sl@0: are (still) initialized, before calling through function pointers. Before, sl@0: they would call and might end up calling unloaded object code. (JL) sl@0: sl@0: 11/15/96 (bug fix) Fixed core dump in Windows socket initialization routine sl@0: if sockets were not installed on the system. Before, it was not properly sl@0: checking the result of attempting to load the socket DLL, so it would call sl@0: through uninitialized function pointers. (JL) sl@0: sl@0: 11/15/96 (bug fix) Fixed memory leak in Windows sockets which left socket sl@0: DLL handle open and could hold the socket DLL in memory uneccessarily, sl@0: until a reboot. (JL) sl@0: sl@0: 12/4/96 (bug fix) Fixed bug in Macintosh socket code that could result sl@0: in lost data if a client was closed too soon after sending data. (RJ) sl@0: sl@0: 12/17/96 (bug fix) Fixed deadlock bug in Windows sockets due to losing an sl@0: event. This was happening because of an interaction between buffering and sl@0: nonblocking mode on sockets. Now switched to sockets being blocking by sl@0: default, so we are also no longer emulating blocking through a private sl@0: event loop. (JL) sl@0: sl@0: 1/21/97 (performance bug fix) Client TCP connections were slow to create sl@0: because getservbyname was always called on the port. Now this is only sl@0: done if Tcl_GetInt fails. (BW) sl@0: sl@0: 1/21/97 (configuration fix) Made it possible to override TCL_PACKAGE_PATH sl@0: during make. Previously it was only set during autoconf process. sl@0: sl@0: 1/29/97 (bug fix) Fixed some problems with the clock command that sl@0: impacted how dates were scaned after the year 2000. (RJ) sl@0: sl@0: ----------------- Released 7.6p2, 1/31/97 ----------------------- sl@0: sl@0: 2/5/97 (bug fix) Fixed a bug where in CR-LF translation mode, \r bytes sl@0: in the input stream were not being handled correctly. (JL) sl@0: sl@0: 2/24/97 (bug fix) Fix bug with exec under Win32s not being able to create sl@0: stderr file which caused all execs to fail. Fixed temp file leak under sl@0: Win32s. Fixed optional parameter bug with SearchPath that only happened sl@0: under Win32s 1.25. (CCS) sl@0: sl@0: ---------------------------------------------------------- sl@0: Changes for Tcl 7.6 go above this line. sl@0: Changes for Tcl 7.7 go below this line. sl@0: ---------------------------------------------------------- sl@0: sl@0: 5/8/96 (new feature) Added Tcl_Ungets C API for putting a sequence of bytes sl@0: into a channel's input buffer. This can be used for "push" model channels sl@0: where the input is obtained via callbacks instead of by request of the sl@0: generic IO code. No Tcl procedure yet. (JL) sl@0: sl@0: 11/15/96 (new feature) Implemented hidden commands. New C APIs: sl@0: Tcl_HideCommand -- hides an existing exposed command. sl@0: Tcl_ExposeCommand -- exposes an existing hidden command. sl@0: New tcl APIs: sl@0: interp invokehidden -- invokes a hidden command in a slave. sl@0: interp hide -- hides an existing exposed command. sl@0: interp expose -- exposes an existing hidden command. sl@0: interp hidden -- returns a list of hidden commands. sl@0: The implementation of Safe Tcl now uses the new hidden commands facility sl@0: to implement the safe base, instead of deleting the commands from a safe sl@0: interpreter. (JL) sl@0: sl@0: 11/15/96 (new feature) Implemented the safe base, a mechanism for sl@0: installing and requesting security policies, purely in Tcl code. Overloads sl@0: the package command to also allow an interpreter to "require" a policy. The sl@0: following new library commands are provided: sl@0: tcl_safeCreateInterp -- creates a slave an initializes the sl@0: policy mechanism. sl@0: tcl_safeInitInterp -- initializes an existing slave with the sl@0: policy mechanism. sl@0: tcl_safeDeleteInterp -- deletes a slave and deinitializes the sl@0: policy mechanism. sl@0: Added a new file to the library, safeinit.tcl, to hold implementation. (JL) sl@0: On 7/9/97, removed the policy loading mechanism from the Safe Base. Left sl@0: only the Safe Base aliases dealing with auto-loading and source. (JL) sl@0: sl@0: 12/6/96 (new feature) Implemented Tcl_Finalize, an API that should be sl@0: called by a process when it is done using Tcl. This API runs all the exit sl@0: handlers to allow them to clean up resources etc. (JL) sl@0: sl@0: 12/17/96 (new feature) Add an http Tcl script package to the Tcl library. sl@0: This package implements the client side of HTTP/1.0; the GET, HEAD, sl@0: and POST requests. (BW) sl@0: sl@0: 1/21/97 (new feature) Added a "marktrusted" subcommand to the "interp" and sl@0: to the interpreter object command. It removes the "safe" mark on an sl@0: interpreter and disables hard-wired checks for safety in the C sources. (JL) sl@0: sl@0: 1/21/97 (removed feature) Removed "vwait" from set of commands available in sl@0: a safe interpreter. (JL) sl@0: sl@0: 2/11/97 (new feature, bug fix) http package. Added -accept to http_config sl@0: so you can set the Accept header. Added -handler option to http_get so sl@0: you can supply your own data handler. Also fixed POST operation to sl@0: set the correct MIME type on the request. (BW) sl@0: sl@0: ---------------------------------------------------------- sl@0: Changes for Tcl 7.7 go above this line. sl@0: Changes for Tcl 8.0 go below this line. sl@0: ---------------------------------------------------------- sl@0: sl@0: 9/17/96 (bug fix) Using "upvar" it was possible to turn an array element sl@0: into an array itself. Changed to disallow this; it was quirky and didn't sl@0: really work correctly anyway. (JO) sl@0: sl@0: 10/21/96 (new feature) The core of the Tcl interpreter has been replaced sl@0: with an on-the-fly compiler that translates Tcl scripts to bytecoded sl@0: instructions; a new interpreter then executes the bytecodes. The compiler sl@0: introduces only a few minor changes at the level of Tcl scripts. The biggest sl@0: changes are to expressions and lists. sl@0: - A second level of substitutions is no longer done for expressions. sl@0: This substantially improves their execution time. This means that sl@0: the expression "$x*4" produces a different result than in the past sl@0: if x is "$y+2". Fortunately, not much code depends on the old sl@0: two-level semantics. Some expressions that do, such as sl@0: "expr [join $list +]" can be recoded to work in Tcl8.0 by adding sl@0: an eval: e.g., "eval expr [join $list +]". sl@0: - Lists are now completely parsed on the first list operation to sl@0: create a faster internal representation. In the past, if you had a sl@0: misformed list but the erroneous part was after the point you sl@0: inserted or extracted an element, then you never saw an error. sl@0: In Tcl8.0 an error will be reported. This should only effect sl@0: incorrect programs that took advantage of behavior of the old sl@0: implementation that was not documented in the man pages. sl@0: Other changes to Tcl scripts are discussed in the web page at sl@0: http://www.scriptics.com/doc/compiler.html. (BL) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 10/21/96 (new feature) In earlier versions of Tcl, strings were used as a sl@0: universal representation; in Tcl 8.0 strings are replaced with Tcl_Obj sl@0: structures ("objects") that can hold both a string value and an internal sl@0: form such as a binary integer or compiled bytecodes. The new objects make it sl@0: possible to store information in efficient internal forms and avoid the sl@0: constant translations to and from strings that occurred with the old sl@0: interpreter. There are new many new C APIs for managing objects. Some of the sl@0: new library procedures for objects (such as Tcl_EvalObj) resemble existing sl@0: string-based procedures (such as Tcl_Eval) but take advantage of the sl@0: internal form stored in Tcl objects for greater speed. Other new procedures sl@0: manage objects and allow extension writers to define new kinds of objects. sl@0: See the manual entries doc/*Obj*.3 (BL) sl@0: sl@0: 10/24/96 (bug fix) Fixed memory leak on exit caused by some IO related sl@0: data structures not being deallocated on exit because their refcount was sl@0: artificially boosted. (JL) sl@0: sl@0: 10/24/96 (bug fix) Fixed core dump in Tcl_Close if called with NULL sl@0: Tcl_Channel. (JL) sl@0: sl@0: 11/19/96 (new feature) Added library procedures for finding word sl@0: breaks in strings in a platform specific manner. See the library.n sl@0: manual entry for more information. (SS) sl@0: sl@0: 11/22/96 (feature improvements) Added support for different levels of sl@0: tracing during bytecode compilation and execution. This should help in sl@0: tracking down suspected problems with the compiler or with converting sl@0: existing code to use Tcl8.0. Two global Tcl variables, traceCompile sl@0: and traceExec, can be set to generate tracing information in stdout: sl@0: - traceCompile: 0 no tracing (default) sl@0: 1 trace compilations of top level commands and procs sl@0: 2 trace and display instructions for all compilations sl@0: - traceExec: 0 no tracing sl@0: 1 trace only calls to Tcl procs sl@0: 2 trace invocations of all commands including procs sl@0: 3 detailed trace showing the result of each instruction sl@0: traceExec >= 2 provides a one line summary of each called command and sl@0: its arguments. Commands that have been "compiled away" such as set are sl@0: not shown. (BL) sl@0: sl@0: 11/30/96 (bug fix) The command "info nameofexecutable" could sometimes sl@0: return the name of a directory. (JO) sl@0: sl@0: 11/30/96 (feature improvements) Changed the code in library/init.tcl sl@0: that reads in pkgIndex.tcl so that (a) it reads the files from child sl@0: directories before those in the parent, so that the parent gets sl@0: precedence, and (b) it doesn't quit if there is an error in a sl@0: pkgIndex.tcl file; instead, it prints an error message on standard sl@0: error and continues. (JO) sl@0: sl@0: 10/5/96 (feature improvements) Partial implementation of binary string sl@0: support: the ability for Tcl string values to contain embedded null bytes. sl@0: Changed the Tcl object-based APIs to take a byte pointer and length pair sl@0: instead of a null-terminated C string. Modified several object type managers sl@0: to support binary strings but not, for example, the list type manager. sl@0: Existing string-based C APIs are unchanged and will truncate binary sl@0: strings. Compiled scripts containing nulls are also truncated. (BL) sl@0: sl@0: 12/12/96 (feature change) Removed the commands "cp", "mkdir", "mv", sl@0: "rm", and "rmdir" from the Macintosh version of Tcl. They were never sl@0: officially supported and their functionality is now available via sl@0: the file command. (RJ) sl@0: sl@0: ----------------- Released 8.0a1, 12/20/96 ----------------------- sl@0: sl@0: 1/7/97 (bug fix) Under Windows, "file stat c:" was returning error instead sl@0: of stat for current dir on c: drive. sl@0: sl@0: 1/10/97 (new feature) Added Tcl_GetIndexFromObj procedure for quick sl@0: lookups of keyword arguments. (JO) sl@0: sl@0: 1/12/97 (new feature) Serial IO channel drivers for Windows and Unix, sl@0: available by using Tcl open command to open pseudo-files like "com1:" or sl@0: "/dev/ttya". New option to Tcl fconfigure command for serial files: sl@0: "-mode baud,parity,data,stop" to specify baud rate, parity, data bits, and sl@0: stop bits. Serial IO is not yet available on Mac. sl@0: sl@0: 1/16/97 (feature change) Restored the Tcl7.x "two level substitution sl@0: semantics" for expressions. Expressions not enclosed in braces are sl@0: implemented, in general, by calling the expr command procedure sl@0: (Tcl_ExprObjCmd) at runtime after the Tcl interpreter has already done a sl@0: first round of substitutions. This is slow (about Tcl7.x speed) because new sl@0: code for the expression is generally compiled each time. However, if the sl@0: expression has only variable substitutions (and not command substitutions), sl@0: "optimistic" fast code is generated inline. This inline code will fail if a sl@0: second round of substitutions is needed (i.e., if the value of a substituted sl@0: variable itself requires more substitutions). The optimistic code will sl@0: catch the error and back off to call the slower but guaranteed correct sl@0: expr command procedure. (BL) sl@0: sl@0: 1/16/97 (feature improvements) Added Tcl_ExprLongObj and Tcl_ExprDoubleObj sl@0: to round out expression-related procedures. (BL) sl@0: sl@0: 1/16/97 (feature change) Under Windows, at startup the environment variables sl@0: "path", "comspec", and "windir" in any capitalization are converted sl@0: automatically to upper case. The PATH variable could be spelled as path, sl@0: Path, PaTh, etc. and it makes programming rather annoying. All other sl@0: environment variables are left alone. (CS) sl@0: sl@0: 1/20/97 (new features) Rewrote the "lsort" command: sl@0: - The new version is based on reentrant merge sort code provided sl@0: by Richard Hipp, so it eliminates the reentrancy and stability sl@0: problems with the old qsort-based implementation. sl@0: - The new version supports a -dictionary option for sorting, and sl@0: it also supports a -index option for sorting lists using one sl@0: element for comparison. sl@0: - The new version is an object command, so it works well with the sl@0: Tcl compiler, especially in conjunction with the new -index sl@0: option. When the -index option is used, this version of lsort sl@0: is more than 100 times faster than the Tcl 7.6 lsort, which had sl@0: to use the -command option to get the same effect. (JO) sl@0: sl@0: 1/20/97 (feature improvements) Added the improved debugging support for Tcl sl@0: objects prototyped by Karl Lehenbauer . sl@0: If TCL_MEM_DEBUG is defined, the object creation calls use Tcl_DbCkalloc sl@0: directly in order to record the caller's source file name and line sl@0: number. (BL) sl@0: sl@0: 1/21/97 (removed feature) Desupported the tcl_precision variable: if sl@0: set, it is ignored. Tcl now uses the full 17 digits of precision when sl@0: converting real numbers to strings (with the new object system real sl@0: numbers are rarely converted to strings so there is no efficiency sl@0: disadvantage to printing all 17 digits; the new scheme improves sl@0: accuracy and simplifies several APIs). (JO) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 1/21/97 (feature change) Removed the "interp" argument for the sl@0: procedures Tcl_GetStringFromObj, Tcl_StringObjAppend, and sl@0: Tcl_StringObjAppendObj. Also removed the "interp" argument for sl@0: the updateStringProc procedure in Tcl_ObjType structures. With sl@0: the tcl_precision changes above, these are no longer needed. (JO) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0a1, but not with Tcl 7.6 *** sl@0: sl@0: 1/22/97 (bug fix) Fixed http.tcl so that http_reset does not result in sl@0: an extra call to the command callback. In addition, if the transaction sl@0: gets a premature eof, the state(status) is "eof", not "ok". (BW) sl@0: sl@0: ----------------- Released 8.0a2, 1/24/97 ----------------------- sl@0: sl@0: 1/29/97 (feature change) Changed how two digit years are parsed in the sl@0: clock command. The old interface just added 1900 which will seem sl@0: broken by the year 2000. The new scheme follows the POSIX standard sl@0: and treats dates 70-99 as 1970-1999 and dates 00-38 as 2000-2038. All sl@0: other two digit dates are undefined. (RJ) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 2/4/97 (bug fix) Fixed bug in clock code that dealt with relative sl@0: dates. Using the relative month code you could get an invalid date sl@0: because it jumped into a non-existant day. (For example, Jan 31 sl@0: to Feb 31.) The code now will return the last valid day of the sl@0: month in these situations. Thanks to Hume Smith for sending in sl@0: this bug fix. (RJ) sl@0: sl@0: 2/10/97 (feature change) Eliminated Tcl_StringObjAppend and sl@0: Tcl_StringObjAppendObj procedures, replaced them with Tcl_AppendToObj sl@0: and Tcl_AppendStringsToObj procedures. Added new procedure sl@0: Tcl_SetObjLength. (JO) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2, but not with Tcl 7.6 *** sl@0: sl@0: 2/10/97 (new feature) Added Tcl_WrongNumArgs procedure for generating sl@0: error messages about incorrect number of arguments. (JO) sl@0: sl@0: 2/11/97 (new feature, bug fix) http package. Added -accept to http_config sl@0: so you can set the Accept header. Added -handler option to http_get so sl@0: you can supply your own data handler. Also fixed POST operation to sl@0: set the correct MIME type on the request. (BW) sl@0: sl@0: 2/22/97 (bug fix) Fixed bug that caused $tcl_platform(osVersion) to be sl@0: computed incorrectly under AIX. (JO) sl@0: sl@0: 2/25/97 (new feature, feature change) Added support for both int and long sl@0: integer objects. Added Tcl_NewLongObj/Tcl_GetLongFromObj/Tcl_SetLongFromObj sl@0: procedures and renamed the Tcl_Obj internalRep intValue member to sl@0: longValue. Tcl_GetIntFromObj now checks for integer values too large to sl@0: represent as non-long integers. Changed Tcl_GetAllObjTypes to sl@0: Tcl_AppendAllObjTypes. (BL) sl@0: sl@0: 3/5/97 (new feature) Added new Tcl_SetListObj procedure to round out sl@0: collection of procedures that set the type and value of existing Tcl sl@0: objects. (BL) sl@0: sl@0: 3/6/97 (new feature) Added -global flag for interp invokehidden. (JL) sl@0: sl@0: 3/6/97 (new feature, feature change) Added isNativeObjectProc field to the sl@0: Tcl_CmdInfo structure to indicate (when 1) if the command has an sl@0: object-based command procedure. Removed the nameLength arg from sl@0: Tcl_CreateObjCommand since command names can't contain null characters. (BL) sl@0: sl@0: 3/6/97 (bug fix) Fixed bug in "unknown" procedure that caused auto- sl@0: loading to fail on commands whose names begin with digits. (JO) sl@0: sl@0: 3/7/97 (bug fix) Auto-loading now works in Safe Base. Safe interpreters sl@0: only accept the Version 2 and onwards tclIndex files. (JL) sl@0: sl@0: 3/13/97 (bug fix) Fixed core dump due to interaction between aliases and sl@0: hidden commands. Bug found by Lindsay Marshall. (JL) sl@0: sl@0: 3/14/97 (bug fix) Fixed mac bugs relating to time. The -gmt option sl@0: now adjusts the time in the correct direction. (Thanks to Ed Hume for sl@0: reporting a fix to this problem.) Also fixed file "mtime" etc. to sl@0: return times from GMT rather than local time zone. (RJ) sl@0: sl@0: 3/18/97 (feature change) Declaration of objv in Tcl_ObjCmdProc function sl@0: changed from "Tcl_Obj *objv[]" to "Tcl_Obj *CONST objv[]". All Tcl object sl@0: commands changed to use new declaration of objv. Naive translation of sl@0: string-based command procs to object-based command procs could very easily sl@0: have yielded code where the contents of the objv array were changed. This sl@0: is not a problem with string-based command procs, but doing something as sl@0: simple as objv[2] = objv[3] would corrupt the runtime stack and cause Tcl to sl@0: crash. Introduced CONST in declaration of objv so that attempted assignment sl@0: of new pointer values to elements of the objv array will be caught by the sl@0: compiler. (CCS) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 *** sl@0: sl@0: 3/19/97 (bug fix) Fixed panic due to object sharing. The root cause was sl@0: that old code was using Tcl_ResetResult instead of Tcl_ResetObjResult. (JL) sl@0: sl@0: 3/20/97 (new feature) Added a new subcommand for the file sl@0: command. file attributes filename can give a list of platform-specific sl@0: options (such as file/creator type on the Mac, permissions on Unix) or sl@0: set the values of them. Added a new subcommand for the file sl@0: command. file nativename name gives back the platform-specific form sl@0: for the file. This is useful when the filename is needed to pass to sl@0: the OS, such as exec under Windows 95 or AppleScript on the Mac. For sl@0: more info, see file.n. (SRP) sl@0: sl@0: 3/24/97 (removed feature) Removed the tcl_safePolicyPath procedure. Now sl@0: the policy path is computed from the auto_path by appending the directory sl@0: 'policies' to each element. Also fixed several bugs in automatic tracking sl@0: of auto_path by computed policy path. (JL) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 *** sl@0: sl@0: 4/8/97 (new feature) If the variable whose name is passed to lappend doesn't sl@0: already exist, and there are no value arguments, lappend now creates the sl@0: variable with an empty value instead of returning an error. Change suggested sl@0: by Tom Tromey. (BL) sl@0: sl@0: 4/9/97 (feature change) Changed the name of the TCL_PART1_NOT_PARSED flag to sl@0: TCL_PARSE_PART1. (BL) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 *** sl@0: sl@0: 4/10/97 (bug fixes) Fixed various compilation-related bugs: sl@0: - "UpdateStringOfCmdName should never be invoked" panic. sl@0: - Bad code generated for expressions not in {}'s inside catch commands. sl@0: - Segmentation fault in some command procedures when two argument sl@0: object pointers refer to the same object. sl@0: - Second level of substitutions were never done for expressions not sl@0: in {}'s that consist of a single variable reference: e.g., sl@0: "set x 27; set bool {$x}; if $bool {puts foo}" would fail with error. sl@0: - Bad code generated when code storage was grown while compiling some sl@0: expressions: ones with compilation errors or consisting of only a sl@0: variable reference. sl@0: - Bugs involving multiple interpreters: wasn't checking that a sl@0: procedure's code was compiled for the same interpreter as the one sl@0: executing it, and didn't invalidate code on hidden-exposed command sl@0: transitions. sl@0: - "Bad stack top" panic when executing scripts that require a huge sl@0: amount of stack space. sl@0: - Incorrect sharing of code for procedure bodies, and procedure code sl@0: deallocated before last execution of the procedure finished. sl@0: - Fixed compilation of expression words in quotes. For example, sl@0: if "0 < 3" {puts foo}. sl@0: - Fixed performance bug in array set command with large assignments. sl@0: - Tcl_SetObjLength segmentation fault setting length of empty object. sl@0: - If Tcl_SetObjectResult was passed the same object as the interpreter's sl@0: result object, it freed the object instead of doing nothing. Bug fix sl@0: by Michael J. McLennan. sl@0: - Tcl_ListObjAppendList inserted elements from the wrong list. Bug fix sl@0: by Michael J. McLennan. sl@0: - Segmentation fault if empty variable list was specified in a foreach sl@0: command. Bug fix by Jan Nijtmans. sl@0: - NULL command name was always passed to Tcl_CreateTrace callback sl@0: procedure. sl@0: - Wrong string representation generated for the value LONG_MIN. sl@0: For example, expr 1<<31 printed incorrectly on a 32 bit machine. sl@0: - "set {a($x)} 1" stored value in wrong variable. sl@0: - Tcl_GetBooleanFromObj was not checking for garbage after a numeric sl@0: value. sl@0: - Garbled "bad operand type" error message when evaluating expressions sl@0: not surrounded by {}'s. (BL) sl@0: sl@0: 4/16/97 (new feature) The expr command now has the "rand()" and sl@0: "srand()" functions for getting random numbers in expr. (RJ) sl@0: sl@0: 4/23/97 (bug fix) Fixed core dump in bgerror when the error handler command sl@0: deletes the current interpreter. Found by Juergen Schoenwald. (JL) sl@0: sl@0: 4/23/97 (feature change) The notifier interfaces have been redesigned sl@0: to make embedding in applications with external event loops possible. sl@0: A number of interfaces in the notifier and the channel drivers have sl@0: changed. Refer to the Notifier.3 and CrtChannel.3 manual entries for sl@0: more details. (SS) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 4/23/97 (removed feature) The Tcl_File interfaces have been removed. sl@0: The Tcl_CreateFileHandler/Tcl_DeleteFileHandler interfaces now take sl@0: Unix fd's and are only supported on the Unix platform. sl@0: Tcl_GetChannelFile has been replaced with Tcl_GetChannelHandle. sl@0: Tcl_MakeFileChannel now takes a platform specific file handle. (SS) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 4/23/97 (removed feature) The modal timeout interface has been sl@0: removed (Tcl_CreateModalTimeout/Tcl_DeleteModalTimeout) (SS) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 4/23/97 (feature change) Channel drivers are now required to correctly sl@0: implement blocking behavior when they are in blocking mode. (SS) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 4/23/97 (new feature) Added the "binary" command for manipulating sl@0: binary strings. Also, changed the "puts", "gets", and "read" commands sl@0: to preserve embedded nulls. (SS) sl@0: sl@0: 4/23/97 (new feature) Added tcl_platform(byteOrder) element to the sl@0: tcl_platform array to identify the native byte order for the current sl@0: host. (SS) sl@0: sl@0: 4/23/97 (bug fix) Fixed bug in date parsing around year boundaries. (SS) sl@0: sl@0: 4/24/97 (bug fix) In the process of copying a file owned by another user, sl@0: Tcl was changing the owner of the copy back to the owner of the original sl@0: file, therefore causing further file operations to fail because the current sl@0: user didn't own the copy anymore. The owner of the copy is now left as the sl@0: current user. (CCS) sl@0: sl@0: 4/24/97 (feature change) Under Windows, don't automatically uppercase the sl@0: environment variable "windir" -- it's supposed to be lower case. (CCS) sl@0: sl@0: 4/29/97 (new feature) Added namespace support based on a namespace sl@0: implementation by Michael J. McLennan of Lucent Technologies. A namespace sl@0: encapsulates a collection of commands and variables to ensure that they sl@0: won't interfere the commands and variables of other namespaces. The global sl@0: namespace holds all global variables and commands. Additional namespaces are sl@0: created with the new namespace command. The new variable command lets you sl@0: create Tcl variables inside a namespace. The names of Tcl variables and sl@0: commands may now be qualified by the name of the namespace containing them. sl@0: The key namespace-related commands are summarized below: sl@0: - namespace ?eval? name arg ?arg...? sl@0: Used to define the commands and variables in a namespace. sl@0: Optionally creates the namespace. sl@0: - namespace export ?-clear? ?pattern pattern...? sl@0: Specifies which commands are exported from a namespace. These sl@0: are the ones that can be imported into another namespace. sl@0: - namespace import ?-force? ?pattern pattern...? sl@0: Makes the specified commands accessible in the current namespace. sl@0: - namespace current sl@0: Returns the name of the current namespace. sl@0: - variable name ?value? ?name ?value?...? sl@0: Creates one or more namespace variables. (BTL) sl@0: sl@0: 5/1/97 (bug fix) Under Windows, file times were reported in GMT. Should be sl@0: reported in local time. (CCS) sl@0: sl@0: 5/2/97 (feature change) Changed the name of the two Tcl variables used for sl@0: tracing bytecode compilation and execution to tcl_traceCompile and sl@0: tcl_traceExec respectively. These variables are now documented in the sl@0: tclvars man page. (BL) sl@0: sl@0: 5/5/97 (new feature) Support "end" as the index for "lsort -index". (BW) sl@0: sl@0: 5/5/97 (bug fixes) Cleaned up the way the http package resets connections (BW) sl@0: sl@0: 5/8/97 (feature change) Newly created Tcl objects now have a reference count sl@0: of zero instead of one. This simplifies C code that stores newly created sl@0: objects in Tcl variables or in data structures such as list objects. That C sl@0: code must increment the new object's reference count since the variable or sl@0: data structure will contain a long-term reference to the object. Formerly, sl@0: when new objects started out with reference count one, it was necessary to sl@0: decrement the new object's reference count after the store to make sure it sl@0: was left with the correct value; this is no longer necessary. (BL) sl@0: sl@0: 5/9/97 (new feature) Added the Tcl_GetsObj interface that takes an sl@0: object reference instead of a dynamic string (as in Tcl_Gets). (SS) sl@0: sl@0: 5/12/97 (new feature) Added Tcl_CreateAliasObj and Tcl_GetAliasObj C APIs sl@0: to allow an alias command to be created with a vector of Tcl_Obj structures sl@0: and to get the vector back later. (JL) sl@0: sl@0: 5/12/97 (feature change) Changed Tcl_ExposeCommand and Tcl_HideCommand to sl@0: leave an object result instead of a string result. (JL) sl@0: sl@0: 5/14/97 (feature change) Improved the handling of the interpreter result. sl@0: This is still either an object or a string, but the two values are now kept sl@0: consistent unless some C code reads or writes interp->result directly. See sl@0: the SetResult man page for details. Removed the Tcl_ResetObjResult sl@0: procedure. (BL) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 *** sl@0: sl@0: 5/16/97 (new feature) Added "fcopy" command to move data between sl@0: channels. Refer to the manual page for more information. Removed the sl@0: "unsupported0" command since it is obsolete now. (SS) sl@0: sl@0: 5/16/97 (new feature) Added Tcl_GetStringResult procedure to allow programs sl@0: to get an interpreter's result as a string. If the result was previously set sl@0: to an object, this procedure will convert the object to a string. Use of sl@0: Tcl_GetStringResult is intended to replace direct access to interp->result, sl@0: which is not safe. (BL) sl@0: sl@0: 5/20/97 (new features) Fixed "fcopy" to return the number of bytes sl@0: transferred in the blocking case. Updated the http package to use sl@0: fcopy instead of unsupported0. Added -timeout and -handler options to sl@0: http_get. http_get is now blocking by default. It is only non-blocking sl@0: if you supply a -command argument. (BW) sl@0: sl@0: 5/22/97 (bug fix) Fixed several bugs in the "lsort" command having to do sl@0: with the -dictionary option and the presence of numbers embedded in the sl@0: strings. (JO) sl@0: sl@0: ----------------- Released 8.0b1, 5/27/97 ----------------------- sl@0: sl@0: 6/2/97 (bug fix) Fixed bug in startup code that caused a problem in sl@0: finding the library files when they are installed in a directory sl@0: containing a space in the name. (SS) sl@0: sl@0: 6/2/97 (bug fix) Fixed bug in Unix notifier where the select mask was sl@0: not being cleared under some circumstances. (SS) sl@0: sl@0: 6/4/97 (bug fix) Fixed bug that prevented creation of Tk widgets in sl@0: namespaces. Tcl_CreateObjCommand and Tcl_CreateCommand now always create sl@0: commands in the global namespace unless the command names are qualified. Tcl sl@0: procedures continue to be created in the current namespace by default. (BL) sl@0: sl@0: 6/6/97 (new features) Added new namespace API procedures sl@0: Tcl_AppendExportList and Tcl_Export to allow C code to get and set a sl@0: namespace's export list. (BL) sl@0: sl@0: 6/11/97 (new feature) Added Tcl_ConcatObj. This object-based routine sl@0: parallels the string-based routine Tcl_Concat. (SRP) sl@0: sl@0: 6/11/97 (new feature) Added Tcl_SetObjErrorCode. This object-based sl@0: routines parallels the string-based routine Tcl_SetErrorCode. (SRP) sl@0: sl@0: 6/12/97 (bug fix) Fix the "unknown" procedure so that wish under Windows sl@0: will exec an external program, instead of always complaining "console1 not sl@0: opened for writing". (CCS) sl@0: sl@0: 6/12/97 (bug fix) Fixed core dump experienced by the following simple sl@0: script: sl@0: interp create x sl@0: x alias exec exec sl@0: interp delete x sl@0: This panic was caused by not installing the new CmdDeleteProc when exec sl@0: got redefined by the alias creation step. Reported by Lindsay Marshal (JL) sl@0: sl@0: 6/13/97 (new features) Tcl objects newly created by Tcl_NewObj now have a sl@0: string representation that points to a shared heap string of length 1. (They sl@0: used to have NULL bytes and typePtr fields. This was treated as a special sl@0: case to indicate an empty string, but made type manager implementations sl@0: complex and error prone.) The new procedure Tcl_InvalidateStringRep is used sl@0: to mark an object's string representation invalid and to free any storage sl@0: associated with the old string representation. (BL) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 *** sl@0: sl@0: 6/16/97 (bug fix) Tcl_ScanCountedElement could leave braces unmatched sl@0: if the string ended with a backslash. (JO) sl@0: sl@0: 6/17/97 (bug fix) Fixed channel event bug where readable events would be sl@0: lost during recursive events loops if the input buffers contained sl@0: data. (SS) sl@0: sl@0: 6/17/97 (bug fix) Fixed bug in Windows socket code that didn't sl@0: reenable read events in the case where an external entity is also sl@0: reading from the socket. (SS) sl@0: sl@0: 6/18/97 (bug fix) Changed initial setting of the notifier service mode sl@0: to TCL_SERVICE_NONE to avoid unexpected event handling during sl@0: initialization. (SS) sl@0: sl@0: 6/19/97 (bug fix/feature change) The command callback to fcopy is now sl@0: called in case of errors during the background copy. This adds a second, sl@0: optional argument to the callback that is the error string. The callback sl@0: in case of errors is required for proper cleanup by the user of fcopy. (BW) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 *** sl@0: sl@0: 6/19/97 (bug fix) Fixed a panic due to the following four line script: sl@0: interp create x sl@0: x alias foo bar sl@0: x eval rename foo blotz sl@0: x alias foo {} sl@0: The problem was that the interp code was not using the actual current name sl@0: of the command to be deleted as a result of un-aliasing foo. (JL) sl@0: sl@0: 6/19/97 (feature change) Pass interp down to the ChannelOption and sl@0: driver specific calls so system errors can be differentiated from syntax sl@0: ones. Changed Tcl_DriverGetOptionProc type. Affects Tcl_GetChannelOption, sl@0: TcpGetOptionProc, TtyGetOptionProc, etc. (DL) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 6/19/97 (new feature) Added Tcl_BadChannelOption for use by by driver sl@0: specific option procedures (Set and Get) to return a complete and sl@0: meaningful error message. (DL) sl@0: sl@0: 6/19/97 (bug fixes) If a system call error occurs while doing an sl@0: fconfigure on tcp or tty/com channel: return the appropriate error sl@0: message (instead of the syntax error one or none). (Fixed for Unix and sl@0: most of the Win and Mac drivers). (DL) sl@0: sl@0: 6/20/97 (feature change) Eval is no longer assumed as the subcommand name sl@0: in namespace commands: you must now write "namespace eval nsName {...}". sl@0: Abbreviations of namespace subcommand names are now allowed. (BL) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 *** sl@0: sl@0: 6/20/97 (feature change) Changed the errorInfo traceback message for sl@0: compilation errors from "invoked from within" to "while compiling". (BL) sl@0: sl@0: 6/20/97 (bug fixes) Fixed various compilation-related bugs: sl@0: - "UpdateStringOfCmdName should never be called" and sl@0: "UpdateStringOfByteCode should never be called" panics. sl@0: - Segfault in TclObjInterpProc getting procedure name after evaluation sl@0: stack is reallocated (grown). sl@0: - Could not use ":" at end of variable and command names. sl@0: - Bad code generated for while and for commands with test expressions sl@0: enclosed in quotes: e.g., "set i 0; while "$i > 5" {}". sl@0: - Command trace procedures would crash if they did a Tcl_EvalObj that sl@0: reallocated the evaluation stack. sl@0: - Break and continue commands did not reset the interpreter result. sl@0: - The Tcl_ExprXXX routines, both string- or object-based, always sl@0: modified the interpreter result even if there was no error. sl@0: - The argument parsing procedure used by several compile procedures sl@0: always treated "]" as end of a command: e.g., "set a ]" would fail. sl@0: - Changed errorInfo traceback message for compilation errors from sl@0: "invoked from within" to "while compiling". sl@0: - Problem initializing Tcl object managers during interpreter creation. sl@0: - Added check and error message if formal parameter to a procedure is sl@0: an array element. (BL) sl@0: sl@0: 6/23/97 (new feature) Added "registry" package to allow manipulation sl@0: of the Windows system registry. See manual entry for details. (SS) sl@0: sl@0: 6/24/97 (feature change) Converted http to a package and added the sl@0: http1.0 subdirectory of the Tcl script library. This means you have sl@0: to do a "package require http" to use this, as advertised in the man page. (BW) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 *** sl@0: sl@0: 6/24/97 (bug fix) Ensure that Tcl_Set/GetVar C APIs, when called without sl@0: TCL_LEAVE_ERR_MSG, don't touch the interp result. (DL) sl@0: sl@0: 6/26/97 (feature change) Changed name of Tcl_ExprStringObj to sl@0: Tcl_ExprObj. (BL) sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 *** sl@0: sl@0: ----------------- Released 8.0b2, 6/30/97 ----------------------- sl@0: sl@0: 7/1/97 (new feature) TCL_BUILD_SHARED flag set in tclConfig.sh sl@0: when Tcl has been built with --enable-shared. A new tclLibObjs sl@0: make target, echoing the list of the .o's needed to build a tcl sl@0: library, is now provided. (DL) sl@0: sl@0: 7/1/97 (feature change) compat/getcwd.c removed and changed the sl@0: only place where getcwd is used so a new USEGETWD flag selects sl@0: the use of the replacement "getwd". Adding this flag is recommended sl@0: for SunOS 4 (because getcwd on SunOS 4 uses a pipe to pwd(1)!). (DL) sl@0: sl@0: 7/7/97 (feature change) The split command now supports binary data (i.e., sl@0: null characters in strings). (BL) sl@0: sl@0: 7/7/97 (bug fix) string first returned the wrong result if the first sl@0: argument string was empty. (BL) sl@0: sl@0: 7/8/97 (bug fix) Fixed core dump in fcopy that could occur when a command sl@0: callback was supplied and an error or eof condition caused no background sl@0: activity. A refcount bug triggered a panic in Tcl_ListObjAppendElement. (BW) sl@0: sl@0: 7/8/97 (bug fix) Relaxed the pattern matching on http_get so you do not sl@0: need a trailing path component. You can now get away with just sl@0: http_get www.scriptics.com (BW) sl@0: sl@0: 7/9/97 (bug fix) Creating anonymous interpreters no longer smashes existing sl@0: commands with names similar to the generated name. Previously creating an sl@0: anonymous interpreter could smash an existing command, now it skips until sl@0: it finds a command name that isn't being used. (JL) sl@0: sl@0: 7/9/97 (feature change) Removed the policy management mechanism from the sl@0: Safe Base; left the aliases to source and load modules, and to do a limited sl@0: form of the "file" command. See entry of 11/15/96. (JL) sl@0: sl@0: 7/9/97 (bug fixes) Fixed various compilation-related bugs: sl@0: - Line numbers in errorInfo now are the same as those in Tcl7.6 unless sl@0: there are compilation errors. Compilation error messages now include the sl@0: entire command in error. sl@0: - Trailing ::s after namespace names weren't being ignored. sl@0: - Could not refer to an namespace variable with an empty name using a sl@0: name of the form "n::". (BL) sl@0: sl@0: 7/9/97 (bug fix) Fixed bug in Tcl_Export that prevented you from exporting sl@0: from other than the current namespace. (BL) sl@0: sl@0: 7/9/97 (bug fix) env.test was removing env var needed for proper finding sl@0: of libraries in child process. (DL) sl@0: sl@0: 7/10/97 (bug fixes/new feature) Cleanup in Tcl_MakeSafe. Less information sl@0: is leaked to safe interps. Error message fixes for interp sub commands. sl@0: Likewise changes in safealias.tcl; tcl_safeCreateInterp can now be called sl@0: without argument to generate the slave name (like in interp create). (DL) sl@0: sl@0: 7/10/97 (bug fixes) Bytecode compiler now generates more detailed sl@0: command location information: subcommands as well as commands now have sl@0: location information. This means command trace procedures now get the sl@0: correct source string for each command in their command parameter. (BL) sl@0: sl@0: 7/22/97 (bug fixes) Performance improvement in Safe interpreters sl@0: handling. Added new mask value to (tclInt.h) Interp.flags record. (DL) sl@0: sl@0: 7/22/97 (bug fix) Fixed panic in 'interp target {} foo'. This bug sl@0: was present since Tcl 7.6. (JL) sl@0: sl@0: 7/22/97 (bug fix) Fixed bug in compilation of procedures in namespaces: the sl@0: procedure's namespace must be used to look up compile procedures, not the sl@0: current namespace. (BL) sl@0: sl@0: 7/22/97 (bug fix) Use of the -channel option of http_get was not setting sl@0: the end of line translations mode on the channel, so copying binary data sl@0: with the -channel option was corrupting the result on non-unix platforms. (BW) sl@0: sl@0: 7/22/97 (bug fixes) file commands and ~user (seg fault and other sl@0: improper returns). (DL) sl@0: sl@0: 7/23/97 (feature change) Reenabled "vwait" in Safe Base. (JL) sl@0: sl@0: 7/23/97 (bug fixes) Fixed two bugs involving read traces on array variables sl@0: in procedures: trace procedures were sometimes not called, and reading sl@0: nonexistant array elements didn't create undefined element variables that sl@0: could later be defined by trace procedures. (BL) sl@0: sl@0: 7/24/97 (bug fix) Windows memory allocation performance was sl@0: superlinear in some cases. Made the Mac allocator generic and changed sl@0: both the Mac and Windows platforms to use the new allocator instead of sl@0: malloc and free. (SS) sl@0: sl@0: 7/24/97 - 8/12/97 (bug fixes/change of features) Completely revamped safe sl@0: sourcing/loading (see safe.n) to hide pathnames, use virtual sl@0: paths tokens instead, improved security in several respects and made it sl@0: more tunable. Multi level interp loading can work too now. Package auto sl@0: loading now works in safe interps as long as the package directory is in sl@0: the auto_path (no deep crawling allowed in safe interps). (DL) sl@0: *** POTENTIAL INCOMPATIBILITY with previous alpha and beta releases *** sl@0: sl@0: 7/24/97 (bug fixes) Made Tcl_SetVar* and Tcl_NewString* treat a NULL value sl@0: as an empty string. (This fixes hairy crash case where you would crash sl@0: because load command for other interps assumed presence of sl@0: errorInfo...). (DL) sl@0: sl@0: 7/28/97 (bug fix) Fixed pkg_mkIndex to understand namespaces. It will sl@0: use the export list of a namespace and create auto_index entries for sl@0: all export commands. Those names are in their fully qualified form in the sl@0: auto_index. Therefore, I tweaked unknown to try both $cmd and ::$cmd. sl@0: Also fixed pkg_mkIndex so you can have "package require" commands inside sl@0: your packages. These commands are ignored, which is mostly ok except sl@0: when you must load another package before loading yours because of sl@0: linking dependencies. (BW) sl@0: sl@0: 7/28/97 (bug fix) A variable created by the variable command now persists sl@0: until the namespace is destroyed or the variable is unset. This is true even sl@0: if the variable has not been initialized; these variables used to be sl@0: destroyed if an error occurred when accessing them. In addition, the "info sl@0: vars" command lists uninitialized namespace variables, while the "info sl@0: exists" command returns 0 for them. (BL) sl@0: sl@0: 7/29/97 (feature change) Changed the http package to use the ::http sl@0: namespace. http_get renamed to http::geturl, http_config renamed to sl@0: http::config, http_formatQuery renamed to http::formatQuery. sl@0: It now provides the 2.0 version of the package. sl@0: The 1.0 version is still available with the old names. sl@0: *** POTENTIAL INCOMPATIBILITY with Tcl 8.0b2 but not with Tcl 7.6 *** sl@0: sl@0: 7/29/97 (bug fix, new feature) Tcl_Main now uses Tcl objects internally to sl@0: preserve NULLs in commands and command output. Added new API procedure sl@0: Tcl_RecordAndEvalObj that resembles Tcl_RecordAndEval but takes an object sl@0: containing a command. (BL) sl@0: sl@0: 7/30/97 (bug fix) Tcl freed strings in the environ array even if it sl@0: did not allocate them. (SS) sl@0: sl@0: 7/30/97 (bug fix) If a procedure is renamed into a different namespace, it sl@0: now executes in the context of that namespace. (BL) sl@0: sl@0: 7/30/97 (bug fix) Prevent renaming of commands into and from namespaces as sl@0: part of hiding them. (JL) sl@0: sl@0: 7/31/97 (feature change) Moved the history command from C to tcl. sl@0: This uses the ::history namespace. The "words" and "substitute" options sl@0: are no longer supported. In addition, the "keep" option without a value sl@0: returns the current keep limit. There is a new "clear" option. sl@0: The unknown command now supports !! again. (BW) sl@0: *** POTENTIAL INCOMPATIBILTY *** sl@0: sl@0: 7/30/97 (bug fix) Made sure that a slave can not fool the master into sl@0: hiding the wrong command. Made sure we don't crash in hiding + namespaces sl@0: issues. (DL) sl@0: sl@0: 8/4/97 (bug fix) Concat, eval, uplevel, and similar commands were sl@0: incorrectly trimming trailing space characters from their arguments sl@0: even when the space characters were preceded by a backslash. (JO) sl@0: sl@0: 8/4/97 (bug fix) Removed the hard link between bgerror and tkerror. sl@0: Only bgerror is supported in tcl core. Tk will still look for a sl@0: tkerror but using regular tcl code for that feature. (DL) sl@0: *** POTENTIAL INCOMPATIBILTY with code relying on the hard link *** sl@0: sl@0: 8/6/97 (bug fix) Reduced size required for compiled bytecodes by using a sl@0: more compact encoding for the command pc-to-source map. (BL) sl@0: sl@0: 8/6/97 (new feature) Added support for additional compilation and execution sl@0: statistics when Tcl is compiled with the TCL_COMPILE_STATS flag. (BL) sl@0: sl@0: 8/7/97 (bug fix) Expressions not in {}s that have a comparison operator as sl@0: the topmost operator must be compiled out-of-line (call the expr cmd at sl@0: runtime) to properly support expr's two-level substitution semantics. An sl@0: example is "set a 2; set b {$a}; puts [expr $b == 2]". (BL) sl@0: sl@0: 8/11/97 (bug fix) The catch command would sometimes crash if a variable name sl@0: was given and the bytecode evaluation stack was grown when executing the sl@0: argument script. (BL) sl@0: sl@0: 8/12/97 (feature change) Reinstated the variable tcl_precision to control sl@0: the number of digits used when floating-point values are converted to sl@0: strings, with default of 12 digits. However, had to make tcl_precision sl@0: shared among all interpreters (except that safe interpreters can't sl@0: modify it). This makes the Tcl 8.0 behavior almost identical to 7.6 sl@0: except that the default precision is 12 instead of 6. (JO) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: ----------------- Released 8.0, 8/18/97 ----------------------- sl@0: sl@0: 8/19/97 (bug fix) Minimal fix for glob -nocomplain bugs: sl@0: "glob -nocomplain unreadableDir/*" was generating an anonymous sl@0: error. More in depth fixes will come with 8.1. (DL). sl@0: sl@0: 8/20/97 (bug fix) Removed check for FLT_MIN in binary command so sl@0: underflow conditions are handled by the compiler automatic sl@0: conversions. (SS) sl@0: sl@0: 8/20/97 (bug fixes) Fixed several compilation-related bugs: sl@0: - Array cmd wasn't detecting arrays that, while compiled, do not yet sl@0: exist (e.g., are marked undefined since they haven't been assigned sl@0: to yet). sl@0: - The GetToken procedure in tclCompExpr.c wasn't recognizing properly sl@0: whether an integer token was invalid. For example, "0x$" is not sl@0: a valid integer. sl@0: - Performance bug in TclExecuteByteCode: the size of its stack frame sl@0: was reduced by over 20% by moving errorInfo code elsewhere. sl@0: - Uninitialized memory read error in tclCompile.c. (BL) sl@0: sl@0: 8/21/97 (bug fix) safe::interpConfigure now behave like Tk widget's sl@0: configure : it changes only the options you provide and you can get sl@0: the current value of any single option. New ?-nested boolean? and sl@0: ?-statics boolean? for all safe::interp* commands but we still sl@0: accept (upward compatibility) the previously defined non valued sl@0: flags ?-noStatics? and ?-nestedLoadOk?. Improved the documentation. (DL). sl@0: sl@0: 8/22/97 (bug fix) Updated PrintDbl.3 to reflect the fact that the sl@0: tcl_precision variable is still used and that it is now shared by all sl@0: interpreters. (BL) sl@0: sl@0: 8/25/97 (bug fix) Fixed array access bug in IllegalExprOperandType sl@0: procedure in tclExecute.c: it was not properly supporting the || and && sl@0: operators. (BL) sl@0: sl@0: 8/27/97 (bug fix) In cases where a channel handler was created with an sl@0: empty event mask while data was still buffered in the channel, the sl@0: channel code would get stuck spinning on a timer that would starve sl@0: idle handlers. This mostly happened in Tk when reading from stdin. (SS) sl@0: sl@0: 9/4/97 (bug fix) Slave interps now inherit the maximum recursion limit sl@0: of their parent instead of starting back at the default. {nb: this still sl@0: does not prevent stack overflow by multi-interps recursion or aliasing} (DL) sl@0: sl@0: 9/11/97 (bug fix) An uninitialized variable in Tcl_WaitPid caused sl@0: pipes to fail to report eof properly under Windows. (SS) sl@0: sl@0: 9/12/97 (bug fix) "exec" was misidentifying some DOS executables as not sl@0: executable. (CCS) sl@0: sl@0: 9/14/97 (bug fix) Was using the wrong structure in sizeof operation in sl@0: tclUnixChan.c. (JL) sl@0: sl@0: 9/15/97 (bug fix) Fixed notifier to break out of do-one-event loop if sl@0: Tcl_WaitForEvent returns 1, so that callers of Tcl_DoOneEvent will get sl@0: a chance to check whether the event just handled is significant. This sl@0: affected mainly recursive calls to Tcl_VWaitCmd; these did not get a sl@0: chance to notice that the variable they were waiting for has been set sl@0: and thus they didn't terminate the vwait. (JL, DL, SS) sl@0: sl@0: 9/15/97 (bug fix) Alignment problems in "binary format" would cause a sl@0: crash on some platforms when formatting floating point numbers. (SS) sl@0: sl@0: 9/15/97 (bug fix) Fixed bug in Macintosh socket code. Now passes all sl@0: tests in socket.test that are not platform specific. (Thanks to Mark sl@0: Roseman for the pointer on the fix.) (RJ) sl@0: sl@0: 9/18/97 (bug fix) Fixed bug -dictionary option of lsort that could sl@0: cause the compare function to run off the end of an array if the sl@0: number only contained 0's. (Thanks to Greg Couch for the report.) (RJ) sl@0: sl@0: 9/18/97 (bug fix) TclFinalizeEnvironment was not cleaning up sl@0: properly. (DL, JI) sl@0: sl@0: 9/18/97 (bug fix) Fixed long-standing bug where an "array get" command sl@0: did not trigger traces on the array or its elements. (BL) sl@0: sl@0: 9/18/97 (bug fixes) Fixed compilation-related bugs: sl@0: - Fixed errorInfo traceback information for toplevel coomands that sl@0: contain nested commands. sl@0: - In the expr command, && and || now accept boolean operands as well sl@0: as numeric ones. (BL) sl@0: sl@0: 9/22/97 (bug fix) Fixed bug that prevented translation modes from being sl@0: set independently for input and output on sockets if input was "auto". (JL) sl@0: sl@0: 9/24/97 (bug fix) Tcl_EvalFile(3) and thus source(n) now works fine on sl@0: files containing NUL chars. (DL) sl@0: sl@0: 9/26/97 (bug fix) Fixed use of uninitialized memory in the environ array sl@0: that later could cause random core dumps. Applies to all platforms. (JL) sl@0: sl@0: 9/26/97 (bug fix) Fixed use of uninitialized memory in socket address data sl@0: structure under some circumstances. This could cause random core dumps. sl@0: This applies only to Unix. (JL) sl@0: sl@0: 9/26/97 (bug fix) Opening files on PC-NFS volumes would cause a hang sl@0: until the system timed after the file was closed. (SS) sl@0: sl@0: 10/6/97 (bug fix) The join(n) command, though objectified, was loosing sl@0: NULs in the joinString and in list elements after the 2nd one. sl@0: Now you can "join $list \0" for instance. (DL) sl@0: sl@0: 10/9/97 (bug fix) Under windows, if env(TMP) or env(TEMP) referred to a sl@0: non-existent directory, exec would fail when trying to create its temporary sl@0: files. (CCS) sl@0: sl@0: 10/9/97 (bug fix) Under mac and windows, "info hostname" would crash if sl@0: sockets were installed but the hostname could not be determined anyhow. sl@0: Tcl_GetHostName() was returning NULL when it should have been returning sl@0: an empty string. (CCS) sl@0: sl@0: 10/10/97 (bug fix) "file attribute /" returned error on windows. (CCS) sl@0: sl@0: 10/10/97 (bug fix) Fixed the auto_load procedure to handle procedures sl@0: defined in namespaces better. Also fixed pgk_mkIndex so it sees procedures sl@0: defined in nested namespaces. Index entries are still only made for sl@0: exported procedures. (BW) sl@0: sl@0: 10/13/97 (bug fix) On unix, for files with unknown group or owner sl@0: attributes, querying the "file attributes" would return an error rather than sl@0: returning the group's or owner's id number, although tha command accepts sl@0: numbers when setting the file's group or owner. (CCS) sl@0: sl@0: 10/22/97 (bug fix) "fcopy" did not eval the callback script at the sl@0: global scope. (SS) sl@0: sl@0: 10/22/97 (bug fix) Fixed the signature of the CopyDone callback used in sl@0: the http package(s) so they can handle error cases properly. (BW) sl@0: sl@0: 10/28/97 (bug fixes) Fixed a problem where lappend would free the Tcl object sl@0: in a variable if a Tcl_ObjSetVar2 failed because of an error calling a trace sl@0: on the variable. (BL) sl@0: sl@0: 10/28/97 (bug fix) Changed binary scan to properly handle sign sl@0: extension of integers on 64-bit or larger machines. (SS) sl@0: sl@0: 11/3/97 (bug fixes) Fixed several bugs: sl@0: - expressions such as "expr ($x)" must be compiled out-of-line sl@0: (call the expr command procedure at runtime) to ensure the correct sl@0: behavior when "$x" is an expression such as "5+10". sl@0: - "array set a {}" now creates a new array var with an empty array sl@0: value if the var didn't already exist. sl@0: - "lreplace $foo end end" no longer returns an error (just an empty sl@0: list) if foo is empty. sl@0: - upvar will no longer create a variable in a namespace that refers sl@0: to a variable in a procedure. sl@0: - deleting a command trace within a command trace callback would sl@0: make the code that calls traces to reference freed memory. sl@0: - significantly sped up "string first" and "string last" (fix from sl@0: darrel@gemstone.com). sl@0: - seg fault in Tcl_NewStringObj() when a NULL is passed as the byte sl@0: pointer argument and Tcl is compiled with -DTCL_MEM_DEBUG. sl@0: - documentation and error msg fixes. (BL) sl@0: sl@0: 11/3/97 (bug fix) Fixed a number of I/O bugs related to word sizes on sl@0: 64-bit machines. (SS) sl@0: sl@0: 11/6/97 (bug fix) The exit code of the first process created by Tcl sl@0: on Windows was not properly reported due to an initialization sl@0: problem. (SS) sl@0: sl@0: ----------------- Released 8.0p1, 11/7/97 ----------------------- sl@0: sl@0: 11/19/97 (bug fix) Fixed bug in linsert where it sometimes accidently sl@0: cleared out a shared argument list object. (BL). sl@0: sl@0: 11/19/97 (bug fix) Autoloading in namespaces was not working properly. sl@0: auto_mkindex is still not really namespace aware but most common sl@0: cases should now be handled properly (see init.test). (BW, DL) sl@0: sl@0: 11/20/97 (enhancement) Made the changes required by the new Apple sl@0: Universal Headers V.3.0, so that Tcl will compile with CW Pro 2. sl@0: sl@0: 11/24/97 (bug fix) Fixed tests in clock test suite that needed the sl@0: -gmt flag set. Thanks to Jan Nijtmans for reporting the problem. (RJ) sl@0: sl@0: ----------------- Released 8.0p2, 11/25/97 ----------------------- sl@0: sl@0: 12/3/97 (bug fix/optimization) Removed uneeded and potentially dangerous sl@0: instances of double evaluations if "if" and "expr" statements from sl@0: the library files. It is recommended that unless you need a double sl@0: evaluation you always use "expr {...}" instead of "expr ..." and sl@0: "if {...} ..." instead of "if ... ...". It will also be faster sl@0: thanks to the byte compiler. (DL) sl@0: sl@0: ---- Shipped as part of the plugin2.0b5 as 8.0p2Plugin1, Dec 8th 97 ---- sl@0: sl@0: 12/8/97 (bug fix) Need to protect the newly accepted channel in an sl@0: accept callback on a socket, otherwise the callback may close it and sl@0: cause an error, which would cause the C code to attempt to close the sl@0: now deleted channel. Bumping the refcount assures that the channel sticks sl@0: around to be really closed in this case. (JL) sl@0: sl@0: 12/8/97 (bug fix) Need to protect the channel in a fileevent so that it sl@0: is not deleted before the fileevent handler returns. (CS, JL) sl@0: sl@0: 12/18/97 (bug fix) In the opt argument parsing package: if the description sl@0: had only flags, the "too many arguments" case was not detected. The default sl@0: value was not used for the special "args" ending argument. (DL) sl@0: sl@0: 1/15/98 (improvement) Moved common part of initScript in common file. sl@0: Moved windows specific initialization to init.tcl so you can initialize sl@0: Tcl in windows without having to call Tcl_Init which is now only sl@0: searching for init.tcl {back ported from 8.1}. (DL) sl@0: sl@0: ---- Shipped as part of the plugin as 8.0p2Plugin2, Jan 15th 98 ---- sl@0: sl@0: 5/27/98 (bug fix) Windows socket driver did not notice new data arriving sl@0: on nonblocking sockets until the event loop was entered. (SS) sl@0: sl@0: 5/27/98 (bug fix) Windows socket driver used FIONREAD, which is not sl@0: supported correctly by WinSock. (SS) sl@0: sl@0: 6/9/98 (bug fix) Generic channel code failed to report readable file sl@0: events on buffered data that was left behind by a gets or read that sl@0: did not consume all available data. (SS) sl@0: sl@0: 6/18/98 (bug fix) Compilation of loop expressions was too aggressive sl@0: and incorrectly inlined non-literal expressions. (SS) sl@0: sl@0: 6/18/98 (bug fix) "info var" and "info locals" incorrectly reported sl@0: the existence of compiler temporary variables. (SS) sl@0: sl@0: 6/18/98 (bug fix) Dictionary sorting used signed character sl@0: comparisons. (SS) sl@0: sl@0: 6/18/98 (bug fix) Compile procs corrupted the exception stack in some sl@0: cases. (SS) sl@0: sl@0: 6/18/98 (bug fix) Array set had erratic behavior when initializing a sl@0: variable from an empty value list. (SS) sl@0: sl@0: 6/18/98 (bug fix) The Windows registry package had a bad bounds check sl@0: that could lead to a crash. (SS) sl@0: sl@0: 6/18/98 (bug fix) The foreach compile proc did not correctly handle sl@0: non-local variable references. (SS) sl@0: sl@0: 6/25/98 (new features) Added name resolution hooks to support [incr Tcl]. sl@0: There are new internal Tcl_*Resolver* APIs to add, query and remove the hooks. sl@0: With this changes it should be possible to dynamically load [incr Tcl] sl@0: as an extension. (MM) sl@0: sl@0: 7/1/97 (bug fix) The commands "info args, body, default, procs" did sl@0: not correctly handle imported procedures. (RJ) sl@0: sl@0: 7/6/98 (improvement) pkg_mkIndex now implements the "package require" sl@0: command. This makes it possible to create index files for packages sl@0: that require another package and then execute code from that package in sl@0: their file. Previously, this would throw an error because the required sl@0: package had not been loaded. The -nopkgrequied flag is provided to sl@0: revert back to the old functionality. (EMS) sl@0: sl@0: 7/6/98 (improvement) back-ported the -direct flag from 8.1 into sl@0: pkg_mkIndex. This results in pkgIndex.tcl files that contain direct sl@0: source or load commands instead of tclPkgSetup commands. (EMS) sl@0: sl@0: 7/6/98 (improvement) made changes to the AuxData items structures to support sl@0: storage of compiled scripts on disk. Also some related minor changes in sl@0: the compilation and execution engine. (EMS) sl@0: sl@0: 6/4/98 (enhancement) Added new internal routines to support inserting sl@0: and deleting from the stat, access, and open-file-channel mechanisms. sl@0: TclAccessInsertProc, TclStatInsertProc, & TclOpenFileChannelInsertProc sl@0: insert pointers to such routines; TclAccessDeleteProc, TclStatDeleteProc, sl@0: & TclOpenFileChannelDeleteProc delete pointers to such routines. See sl@0: the file generic/tclIOUtils.c for more details. (SKS) sl@0: sl@0: 7/1/98 (enhancement) Added a new internal C variable sl@0: tclPreInitScript. This is a pointer to a string that may hold an sl@0: initialization script; If this pointer is non-NULL it is evaluated in sl@0: Tcl_Init() prior to the built-in initialization script defined in the sl@0: file generic/tclInitScript.h. (SKS) sl@0: sl@0: 7/6/98 (bug fix) Removed dead code in PlatformInitExitHandler so that sl@0: the TCL_LIBRARY value can be safely patched in binaries. (BW) sl@0: sl@0: 7/24/98 (enhancement) Incorporated a new version of auto_mkindex that sl@0: can support the [incr Tcl] class structures. This version will index sl@0: all procedures in a source file, not just those where "proc" starts sl@0: at the beginning of the line. If you want the old behavior, use the sl@0: auto_mkindex_old procedure. (MM) sl@0: sl@0: 7/24/98 (feature change) Changed the Windows registry key to be sl@0: HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, and to store the path sl@0: in the default value instead of "Root". Also, this key can be sl@0: specified at compile time in case Tcl is being used in a different sl@0: context where it needs an alternate library path from the standard Tcl sl@0: installation. (SS) sl@0: sl@0: 7/24/98 (feature change) Changed the search order for init.tcl. The sl@0: tcl_library variable can now be set before calling Tcl_Init to avoid sl@0: doing any searches. If it isn't set, then Tcl checks sl@0: env(TCL_LIBRARY), the static value set at compile time, an install sl@0: directory relative to the executable, a source directory relative to sl@0: the executable, and a tcl directory relative to the source heirarchy sl@0: containing the executable. See the comment at the top of sl@0: generic/tclInitScript.h for more details. (SS) sl@0: sl@0: 7/27/98 (config change) Changed the use of the DBGX flag in configure.in sl@0: and the makefile to be TCL_DBGX. Users of tclConfig.sh may need to pass sl@0: this through their configure files with AC_SUBST. (BW) sl@0: sl@0: 729/98 (bug fix) Changed [info body] to return a copy of the body of a sl@0: compiled procedure instead of the body itself, to avoid invalidation sl@0: of the internal rep and loss of the byte-codes. (EMS) sl@0: sl@0: 8/5/98 (bug fix) The platform init code could walk off the end of a sl@0: buffer when reading the PkgPath registry value on Windows. (SS) sl@0: sl@0: 8/5/98 (Windows makefile change) Introduced a set of macros to deal with sl@0: exporting symbols when compiling DLLS on Windows. See win/README for sl@0: details. (EMS) sl@0: sl@0: 8/5/98 (addendum) Added a second Windows registry key under sl@0: HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, named "pkgPath". sl@0: This is a multi-string value used to initialize the tcl_pkgPath sl@0: variable. This is required if extension DLLs are in architecture specific sl@0: subdirectories. (SS) sl@0: sl@0: 8/6/98 (new feature) Added tcl_findLibrary to init.tcl for use by sl@0: extensions, including Tk. This searches in a canonical way for sl@0: an extensions library directory and initialization file. (BW) sl@0: sl@0: 8/10/98 (bug fix) Imported commands used to get lost if the target sl@0: of the import was redefined. Tcl_CreateCommand and Tcl_CreateObjCommand sl@0: were updated to restore import links. (Note that if you rename a command, sl@0: the import links move to the new name, and if you delete a command then sl@0: the import links get lost. These semantics have not changed.) (MC) sl@0: sl@0: -------- Released 8.0.3 to the Tcl Consortium CD-ROM project, 8/10/98 ------ sl@0: sl@0: 9/3/98 (bug fix) Tcl_Realloc was failing under Windows because the sl@0: GlobalReAlloc API was not correctly re-allocating blocks that were sl@0: 32k+. The fix was to use newer Win32 APIs (HeapAlloc, HeapFree, and sl@0: HeapReAlloc.) (BS) sl@0: sl@0: 10/5/98 (bug fix) Fixed bug in pkg_mkIndex that caused some files that do sl@0: a "package require" of packages in the Tcl libraries to give a warning like sl@0: warning: "xx.tcl" provides more than one package ({xx 2.0} {yy 0.3}) sl@0: and generate a broken pkgIndex.tcl file. (EMS) sl@0: sl@0: 10/5/98 (bug fix) Pkg_mkIndex was not doing a case-insensitive comparison sl@0: of extensions to determine whether to load or source a file. Thus, under sl@0: Windows, MYDLLNAME.DLL was sourced, and mydllname.dll loaded. (EMS) sl@0: sl@0: 10/5/98 (new feature) Created a new Tcl_Obj type, "procbody". This object's sl@0: internal representation holds a pointer to a Proc structure. Extended sl@0: TclCreateProc to take both strings and "procbody". (EMS) sl@0: sl@0: 10/13/98 (bug fix) The "info complete" command can now handle strings sl@0: with NULLs embedded. Thanks to colin@field.medicine.adelaide.edu.au sl@0: for providing this fix. (RJ) sl@0: sl@0: 10/13/98 (bug fix) The "lsort -dictionary" command did not properly sl@0: handle some numbers starting with 0. Thanks to Richard Hipp sl@0: for submitting the fix to Scriptics. (RJ) sl@0: sl@0: 10/13/98 (bug fix) The function Tcl_SetListObj was creating an invalid sl@0: Tcl_Obj if the list had zero elements (despite what the comments said sl@0: it would do). Thanks to Sebastian Wangnick for reporting the sl@0: problem. (RJ) sl@0: sl@0: 10/20/98 (new feature) Added tcl_platform(debug) element to the sl@0: tcl_platform array on Windows platform. The existence of the debug sl@0: element of the tcl_platform array indicates that the particular Tcl sl@0: shell has been compiled with debug information. Using sl@0: "info exists tcl_platform(debug)" a Tcl script can direct the sl@0: interpreter to load debug versions of DLLs with the load sl@0: command. (SKS) sl@0: sl@0: 10/20/98 (feature change) The Makefile and configure scripts have been sl@0: changed for IRIX to build n32 binaries instead of the old 32 abi sl@0: format. If you have extensions built with the o32 abi's you will need sl@0: to update them to n32 for them to work with Tcl. (RJ) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 10/23/98 (bug fix) tcl_findLibrary had a stray ] in one of the sl@0: pathnames it searched for the initialization script. tclInitScript.h sl@0: was incorrectly adding the parent of tcl_library to tcl_pkgPath. This sl@0: logic was moved into init.tcl, and the initialization of auto_path was sl@0: documented. Thanks to Donald Porter and Tom Silva for related sl@0: patches. (BW) sl@0: sl@0: 10/29/98 (bug fix) Fixed Tcl_NotifyChannel to use Tcl_Preserve instead sl@0: of Tcl_RegisterChannel so that 1) unregistered channels do not get sl@0: closed after their first fileevent, and 2) errors that occur during sl@0: close in a fileevent script are actually reflected by the close sl@0: command. (BW) sl@0: sl@0: 10/30/98 (bug fix) Overhaul of pkg_mkIndex to deal with transitive sl@0: package requires and packages split among scripts and binary files. sl@0: Also fixed ommision of global for errorInfo in tcl_findLibrary. (BW) sl@0: sl@0: 11/08/98 (bug fix) Fixed the resource command to always detect sl@0: the case where a file is opened a second time with the same sl@0: permissions. IM claims that this will always cause the same sl@0: FileRef to be returned, but in MacOS 8.1+, this is no longer the case, sl@0: so we have to test for this explicitly. (JI) sl@0: sl@0: 11/10/98 (feature change) When compiling with Metrowerk's MSL, use the sl@0: exit function from MSL rather than ExitToShell. This allows MSL to sl@0: clean up its temporary files. Thanks to Vince Darley for this sl@0: improvement. (JI) sl@0: sl@0: ----------------- Released 8.0.4, 11/19/98 ------------------------- sl@0: sl@0: 11/20/98 (bug fix) Handle possible NULL return in TclGetStdFiles. (RJ) sl@0: sl@0: 11/20/98 (bug fix) The dltests would not build on SGI. They reported sl@0: that you could not mix n32 with 032 binaries. The configure script sl@0: has been modified to get the EXTRA_CFLAGS from the tcl configure sl@0: script. [Bug id: 840] (RJ) sl@0: sl@0: 12/3/98 (bug fix) Windows NT creates sockets so they are inheritable sl@0: by default. Fixed socket code so it turns off this bit right after sl@0: creation so sockets aren't kept open by exec'ed processes. [Bug: 892] sl@0: Thanks to Kevin Kenny for this fix. (SS) sl@0: sl@0: 1/11/98 (bug fix) On HP, "info sharedlibextension" was returning sl@0: empty string on static apps. It now always returns ".sl". (RJ) sl@0: sl@0: 1/28/99 (configure change) Now support -pipe option on gcc. (RJ) sl@0: sl@0: 2/2/99 (bug fix) Fixed initialization problem on Windows where no sl@0: searching for init.tcl would be performed if the registry keys were sl@0: missing. (stanton) sl@0: sl@0: 2/2/99 (bug fix) Added support for HKEY_PERFORMANCE_DATA and sl@0: HKEY_DYN_DATA keys in the "registry" command. (stanton) sl@0: sl@0: 2/2/99 (bug fix) ENOTSUP and EOPNOTSUPP clashed on some Linux sl@0: variants. (stanton) sl@0: sl@0: 2/2/99 (enhancement) The "open" command has been changed to use the sl@0: object interfaces. (stanton) sl@0: sl@0: 2/2/99 (bug fix) In some cases Tcl would crash due to an overflow of sl@0: the exception stack resulting from a missing byte code in some sl@0: expressions. (stanton) sl@0: sl@0: 2/2/99 (bug fix) Changed configure so Linux and IRIX shared libraries sl@0: are linked with the system libraries. (stanton) sl@0: sl@0: 2/2/99 (bug fix) Added support for BSDI 4.x (BSD/OS-4*) to the sl@0: configure script. (stanton) sl@0: sl@0: 2/2/99 (bug fix) Fixed bug where upvar could resurrect a namespace sl@0: variable after the namespace had been deleted. (stanton) sl@0: sl@0: 2/2/99 (bug fix) In some cases when creating variables, the sl@0: interpreter result was being modified even if the TCL_LEAVE_ERR_MSG sl@0: flag was set. (stanton) sl@0: sl@0: 2/2/99 (bug fix & new feature) Changed the socket drivers to properly sl@0: handle failures during an async socket connection. Added a new sl@0: fconfigure option "-error" to retrieve the failure message. See the sl@0: socket.n manual entry for details. (stanton) sl@0: sl@0: 2/2/99 (bug fix) Deleting a renamed interp alias could result in a sl@0: panic. (stanton) sl@0: sl@0: 2/2/99 (feature change/bug fix) Changed the behavior of "file sl@0: extension" so that it splits at the last period. Now the extension of sl@0: a file like "foo..o" is ".o" instead of "..o" as in previous versions. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: ----------------- Released 8.0.5, 3/9/99 ------------------------- sl@0: sl@0: ======== Changes for 8.0 go above this line ======== sl@0: ======== Changes for 8.1 go below this line ======== sl@0: sl@0: 6/18/97 (new feature) Tcl now supports international character sets: sl@0: - All C APIs now accept UTF-8 strings instead of iso8859-1 strings, sl@0: wherever you see "char *", unless explicitly noted otherwise. sl@0: - All Tcl strings represented in UTF-8, which is a convenient sl@0: multi-byte encoding of Unicode. Variable names, procedure names, sl@0: and all other values in Tcl may include arbitrary Unicode characters. sl@0: For example, the Tcl command "string length" returns how many sl@0: Unicode characters are in the argument string. sl@0: - For Java compatibility, embedded null bytes in C strings are sl@0: represented as \xC080 in UTF-8 strings, but the null byte at the end sl@0: of a UTF-8 string remains \0. Thus Tcl strings once again do not sl@0: contain null bytes, except for termination bytes. sl@0: - For Java compatibility, "\uXXXX" is used in Tcl to enter a Unicode sl@0: character. "\u0000" through "\uffff" are acceptable Unicode sl@0: characters. sl@0: - "\xXX" is used to enter a small Unicode character (between 0 and 255) sl@0: in Tcl. sl@0: - Tcl automatically translates between UTF-8 and the normal encoding for sl@0: the platform during interactions with the system. sl@0: - The fconfigure command now supports a -encoding option for specifying sl@0: the encoding of an open file or socket. Tcl will automatically sl@0: translate between the specified encoding and UTF-8 during I/O. sl@0: See the directory library/encoding to find out what encodings are sl@0: supported (eventually there will be an "encoding" command that sl@0: makes this information more accessible). sl@0: - There are several new C APIs that support UTF-8 and various encodings. sl@0: See Utf.3 for procedures that translate between Unicode and UTF-8 sl@0: and manipulate UTF-8 strings. See Encoding.3 for procedures that sl@0: create new encodings and translate between encodings. See sl@0: ToUpper.3 for procedures that perform case conversions on UTF-8 sl@0: strings. sl@0: sl@0: 9/18/97 (enhancement) Literal objects are now shared by the ByteCode sl@0: structures created when compiled different scripts. This saves up to 45% sl@0: of the total memory needed for all literals. (BL) sl@0: sl@0: 9/24/97 (bug fixes) Fixed Tcl_ParseCommand parsing of backslash-newline sl@0: sequences at start of command words. Suppressed Tcl_EvalDirect error logging sl@0: if non-TCL_OK result wasn't an error. (BL) sl@0: sl@0: 10/17/97 (feature enhancement) "~username" now refers to the users' home sl@0: directory on Windows (previously always returned failure). (CCS) sl@0: sl@0: 10/20/97 (implementation change) The Tcl parser has been completely rewritten sl@0: to make it more modular. It can now be used to parse a script without actually sl@0: executing it. The APIs for the new parser are not correctly exported, but sl@0: they will eventually be exported and augmented with Tcl commands so that sl@0: Tcl scripts can parse other Tcl scripts. (JO) sl@0: sl@0: 10/21/97 (API change) Added "flags" argument to Tcl_EvalObj, removed sl@0: Tcl_GlobalEvalObj procedure. Added new procedures Tcl_Eval2 and sl@0: Tcl_EvalObjv. (JO) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 10/22/97 (API change) Renamed Tcl_ObjSetVar2 and Tcl_ObjGetVar2 to sl@0: Tcl_SetObjVar2 and Tcl_GetObjVar2 (for consistency with other C APIs) sl@0: and changed the name arguments to be strings instead of objects. (JO) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 10/27/97 (enhancement) Bytecode compiler rewritten to use the new Tcl sl@0: parser. (BL) sl@0: sl@0: 11/3/97 (New routines) Added Tcl_AppendObjToObj, which appends the sl@0: string rep of one Tcl_Obj to another. Added Tcl_GetIndexFromObjStruct, sl@0: which is similar to Tcl_GetIndexFromObj, except that you can give an sl@0: offset between strings. This allows Tcl_GetIndexFromObjStruct to be sl@0: called with a table of records which have strings in them. (SRP) sl@0: sl@0: 12/4/97 (enhancement) New Tcl expression parser added. Added new procedure sl@0: Tcl_ParseExpr and new token types TCL_TOKEN_SUB_EXPR and sl@0: TCL_TOKEN_OPERATOR. Expression compiler is reimplemented to use this sl@0: parser. (BL) sl@0: sl@0: 12/9/97 (bug fix) Tcl_EvalObj() increments/decrements the refcount of the sl@0: script object to prevent the object from deleting itself while in the sl@0: middle of being evaluated. (CCS) sl@0: sl@0: 12/9/97 (bug fix) Memory leak in Tcl_GetsObjCmd(). (CCS) sl@0: sl@0: 12/11/97 (bug fix) Environment array leaked memory when compiled with sl@0: Visual C++. (SS) sl@0: sl@0: 12/11/97 (bug fix) File events and non-blocking I/O did not work on sl@0: pipes under Windows. Changed to use threads to achieve non-blocking sl@0: behavior. (SS) sl@0: sl@0: 12/18/97 (bug fixes) Fixed segfault in "namespace import"; importing a sl@0: procedure that causes a cycle now returns an error. Modified "info procs", sl@0: "info args", "info body", and "info default" to return information about sl@0: imported procedures as well as procedures defined in a namespace. (BL) sl@0: sl@0: 12/19/97 (enhancement) Added new Tcl_GetString() procedure that can be used sl@0: in place of Tcl_GetStringFromObj() if the string representation's length sl@0: isn't needed. (BL) sl@0: sl@0: 12/18/97 (bug fix) In the opt argument parsing package: if the description sl@0: had only flags, the "too many arguments" case was not detected. The default sl@0: value was not used for the special "args" ending argument. (DL) sl@0: sl@0: 1/7/98 (clean up) Moved everything not absolutly necessary out of init.tcl sl@0: procs now in auto.tcl and package.tcl can be autoloaded if needed. (DL) sl@0: sl@0: 1/7/98 (enhancement) tcltest made at install time will search for it's sl@0: init.tcl where it is, even when using virtual path compilation. (DL) sl@0: sl@0: 1/8/98 (os bug workaround) when needed, using a replacement for memcmp so sl@0: string compare "char with high bit set" "char w/o high bit set" returns sl@0: the expected value on all platforms. (DL) sl@0: sl@0: 1/8/98 (unix portability/configure) building from .../unix/targetName/ sl@0: subdirectories and simply using "../configure" should now work fine. (DL) sl@0: sl@0: 1/14/98 (enhancement) Added new regular expression package that sl@0: supports AREs, EREs, and BREs. The new package includes new escape sl@0: characters, meta-syntax, and character classes inside brackets. sl@0: Regexps involving backslashes may behave differently. (MH) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 1/16/98 (os workaround) Under windows, "file volume" was causing chatter sl@0: and/or several seconds of hanging when querying empty floppy drives. sl@0: Changed implementation to call an empirically-derived function that doesn't sl@0: cause this. (CCS) sl@0: sl@0: 1/16/98 (enhancement) Converted regular expressions to a Tcl_Obj type so sl@0: their compiled form gets cached automatically. Reduced NSUBEXP from 100 sl@0: to 20. (BW) sl@0: sl@0: 1/16/98 (documentation) Change unclear documentation and comments for sl@0: functions like Tcl_TranslateFileName() and Tcl_ExternalToUtfDString(). Now sl@0: it explicitly says they take an uninitialized or free DString. A DString sl@0: that is "empty" or "not holding anything" could have been interpreted as one sl@0: currently with a zero length, but with a large dynamically allocated buffer. sl@0: (CCS) sl@0: sl@0: ----------------- Released 8.1a1, 1/22/98 ----------------------- sl@0: sl@0: 1/28/98 (new feature) Added a "-direct" optional flag to pkg_mkIndex sl@0: to generate direct loading package indexes (such those you need sl@0: if you use namespaces and plan on using namespace import just after sl@0: package require). pkg_mkIndex still has limitations regarding sl@0: package dependencies but errors are now ignored and with -direct, correct sl@0: package indexes can be generated even if there are dependencies as long sl@0: as the "package provide" are done early enough in the files. (DL) sl@0: sl@0: 1/28/98 (enhancement) Performance tuning of regexp and regsub. (CCS) sl@0: sl@0: 1/28/98 (bug fix) regexp and regsub with "-indices" returned the byte-offsets sl@0: of the characters in the UTF-8 representation, not the character offsets sl@0: themselves. (CCS) sl@0: sl@0: 1/28/98 (bug fix) "clock format 0 -format %Z -gmt 1" would return the local sl@0: timezone string instead of "GMT" on Solaris and Windows. sl@0: sl@0: 1/28/98 (bug fix) Restore tty settings when closing serial device on Unix. sl@0: This is good behavior when closing real serial devices, essential when sl@0: closing the pseudo-device /dev/tty because the user's terminal settings sl@0: would be left useless, in raw mode, when tcl quit. (CCS) sl@0: sl@0: 1/28/98 (bug fix) Tcl_OpenCommandChannel() was modifying the contents of the sl@0: argv array passed to it, causing problems for any caller that wanted to sl@0: continue to use the argv array after calling Tcl_OpenCommandChannel(). (CCS) sl@0: sl@0: 2/1/98 (bug fix) More bugs with %Z in format string argument to strftime(): sl@0: 1. Borland always returned empty string. sl@0: 2. MSVC always returned the timezone string for the current time, not the sl@0: timezone string for the specified time. sl@0: 3. With MSVC, "clock format 0 -format %Z -gmt 1" would return "GMT" the first sl@0: time it was called, but would return the current timezone string on all sl@0: subsequent calls. (CCS) sl@0: sl@0: 2/1/98 (bug fix) "file stat" was broken on Windows. sl@0: 1. "file stat" of a root directory (local or network) or a relative path that sl@0: resolved to a root directory (c:. when in pwd was c:/) was returning error. sl@0: 2. "file stat" on a regular file (S_IFREG), the st_mode was sign extended to sl@0: a negative int if the platform-dependant type "mode_t" was declared as a sl@0: short instead of an unsigned short. sl@0: 3. "file stat" of a network directory, the st_dev was incorrectly reported sl@0: as the id of the last accessed local drive rather than the id of the sl@0: network drive. (CCS) sl@0: sl@0: 2/1/98 (bug fix) "file attributes" of a relative path that resolved to a sl@0: root directory was returning error. (CCS) sl@0: sl@0: 2/1/98 (bug fix) Change error message when "file attribute" could not sl@0: determine the attributes for a file. Previously it would return different sl@0: error messages on Unix vs. Windows vs. Mac. (CCS) sl@0: sl@0: 2/4/98 (bug fixes) Fixed several instances of bugs where the parser/compiler sl@0: would reach outside the range of allocated memory. Improved the array sl@0: lookup algorithm in set compilation. (DL) sl@0: sl@0: 2/5/98 (change) The TCL_PARSE_PART1 flag for Set/Get(Obj)Var2 C APIs is now sl@0: deprecated and ignored. The part1 is always parsed when the part2 argument sl@0: is NULL. This is to avoid a pattern of errors for extension writers converting sl@0: from string based Tcl_SetVar() to new Tcl_SetObjVar2() and who could easily sl@0: forget to provide the flag and thus get code working for normal variables sl@0: but not for array elements. The performance hit is minimal. A side effect sl@0: of that change is that is is no longer possible to create scalar variables sl@0: that can't be accessed by tcl scripts because of their invalid name sl@0: (ending with parenthesis). Likewise it is also parsed and checked to sl@0: ensure that you don't create array elements of array whose name is a valid sl@0: array element because they would not be accessible from scripts anyway. sl@0: Note: There is still duplicate array elements parsing code. (DL) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 2/11/98 (bug fix) Sharing objects between interps, such as by "interp sl@0: eval" or "send" could cause a crash later when dereferencing an interp sl@0: that had been deleted, given code such as: sl@0: set a {set x y} sl@0: interp create foo sl@0: interp eval foo $a sl@0: interp delete foo sl@0: unset a sl@0: Interp "foo" was gone, but "a" had a internal rep consisting of bytecodes sl@0: containing a dangling pointer to "foo". Unsetting "a" would attempt to sl@0: return resources back to "foo", causing a crash as random memory was sl@0: accessed. The lesson is that that if an object's internal rep depends on sl@0: an interp (or any other data structure) it must preserve that data in sl@0: some fashion. (CCS) sl@0: sl@0: 2/11/98 (enhancement) The "interp" command was returning inconsistent error sl@0: messages when the specified slave interp could not be found. (CCS) sl@0: sl@0: 2/11/98 (bug fix) Result codes like TCL_BREAK and TCL_CONTINUE were not sl@0: propagating through the master/slave interp boundaries, such as "interp sl@0: eval" and "interp alias". TCL_OK, TCL_ERROR, and non-standard codes like sl@0: teh integer 57 work. There is still a question as to whether TCL_RETURN sl@0: can/should propagate. (CCS) sl@0: sl@0: 2/11/98 (bug fix) TclCompileScript() was derefering memory 1 byte before sl@0: start of the string to compile, looking for ']'. (CCS,DL) sl@0: sl@0: 2/11/98 (bug fix) Tcl_Eval2() was derefering memory 1 byte before start sl@0: of the string to eval, looking for ']'. (CCS,DL) sl@0: sl@0: 2/11/98 (bug fix) Compiling "set a(b" was running off end of string. (CCS,DL) sl@0: sl@0: 2/11/98 (bug fix) Windows initialization code was dereferencing sl@0: uninitialized memory if TCL_LIBRARY environment didn't exist. (CCS) sl@0: sl@0: 2/11/98 (bug fix) Windows "registry" command was dereferencing sl@0: uninitialized memory when constructing the $errorCode for a failed sl@0: registry call. (CCS) sl@0: sl@0: 2/11/98 (enhancement) Eliminate the TCL_USE_TIMEZONE_VAR definition from sl@0: configure.in, because it was the same information as the already existing sl@0: HAVE_TM_ZONE definition. The lack of HAVE_TM_ZONE is used to work around a sl@0: Solaris and Windows bug where "clock format [clock sec] -format %Z -gmt 1" sl@0: produces the local timezone string instead of "GMT". (CCS) sl@0: sl@0: 2/11/98 (bug fix) Memleaks and dereferencing of uninitialized memory in sl@0: regexp if an error occurred while compiling a regular expression. (CCS). sl@0: sl@0: 2/18/98 (new feature) Added mutexes and thread local storage in order sl@0: to make Tcl thread safe. For testing purposes, there is a testthread sl@0: command that creates a new thread and an interpreter inside it. See sl@0: thread.test for examples, but this script-level interface is not fixed. sl@0: Each thread has its own notifier instance to manage its own events, sl@0: and threads can post messages to each other's message queue. sl@0: This uses pthreads on UNIX, and native thread support on other platforms. sl@0: You enable this by configuring with --enable-threads. Note that at sl@0: this time *Tk* is still not thread safe. Special thanks to sl@0: Richard Hipp: his earlier implementation inspired this work. (BW, SS, JI) sl@0: sl@0: 2/18/98 (hidden feature change) The way the env() array is shared among sl@0: interpreters changed. Updates to env used to trigger write traces in sl@0: other interpreters. This undocumented feature is no longer implemented. sl@0: Instead, variable tracing is used to keep the C-level environ array in sync sl@0: with the Tcl-level env array. This required adding TCL_TRACE_ARRAY support sl@0: to Tcl_TraceVar2 so that array names works properly. (BW) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 2/18/98 (enhancement) Conditional compilation for unix systems (e.g., sl@0: IRIX, SCO) that use f_bsize instead of st_blksize to determine disk block sl@0: size. (CCS) sl@0: sl@0: 2/23/98 (bug fix) Fixed the emulation of polling selects in the threaded sl@0: version of the Unix notifier. The bug was showing up on a multiprocessor sl@0: as starvation of the notifier thread. (BW) sl@0: sl@0: ----------------- Released 8.1a2, Feb 23 1998 ----------------------- sl@0: sl@0: 9/22/98 (bug fix) Changed the value of TCL_TRACE_ARRAY so it no longer sl@0: conflicts with the deprecated TCL_PARSE_PART1 flag. This should sl@0: improve portability of C code. (stanton) sl@0: sl@0: 10/6/98 (bug fix) The compile procedure for "if" incorrectly attempted sl@0: to match against the literal string "if", resulting in a stack sl@0: overflow when "::if" was compiled. It also would incorrectly accept sl@0: "if" instead of "elsif" in later clauses. (stanton) sl@0: sl@0: 10/15/98 (new feature) Added a "totitle" subcommand to the "string" sl@0: command to convert strings to capitalize the first character of a string sl@0: and lowercase all of the other characters. (stanton) sl@0: sl@0: 10/15/98 (bug fix) Changed regexp and string commands to properly sl@0: handle case folding according to the Unicode character sl@0: tables. (stanton) sl@0: sl@0: 10/21/98 (new feature) Added an "encoding" command to facilitate sl@0: translations of strings between different character encodings. See sl@0: the encoding.n manual entry for more details. (stanton) sl@0: sl@0: 11/3/98 (bug fix) The regular expression character classification sl@0: syntax now includes Unicode characters in the supported sl@0: classes. (stanton) sl@0: sl@0: 11/6/98 (bug fix) Variable traces were causing crashes when upvar sl@0: variables went out of scope. [Bug: 796] (stanton) sl@0: sl@0: 11/9/98 (bug fix) "format" now correctly handles multibyte characters sl@0: in %s format strings. (stanton) sl@0: sl@0: 11/10/98 (new feature) "regexp" now accepts three new switches sl@0: ("-line", "-lineanchor", and "-linestop") that control how regular sl@0: expressions treat line breaks. See the regexp manual entry for more sl@0: details. (stanton) sl@0: sl@0: 11/17/98 (bug fix) "scan" now correctly handles Unicode sl@0: characters. (stanton) sl@0: sl@0: 11/17/98 (new feature) "scan" now supports XPG3 position specifiers sl@0: and the "%n" conversion character. See the "scan" manual entry for sl@0: more details. (stanton) sl@0: sl@0: 11/17/98 (bug fix) The Tcl memory allocator now returns 8-byte aligned sl@0: chunks of memory which improves performance on Windows and avoids sl@0: crashes on other platforms. [Bug: 834] (stanton) sl@0: sl@0: 11/23/98 (bug fix) Applied various regular expression performance bug sl@0: fixes supplied by Henry Spencer. (stanton) sl@0: sl@0: 11/30/98 (bug fix) Fixed various thread related race conditions. [Bug: sl@0: 880 & 607] (stanton) sl@0: sl@0: 11/30/98 (bug fix) Fixed a number of memory overflow and leak sl@0: bugs. [Bug: 584] (stanton) sl@0: sl@0: 12/1/98 (new feaure) Added support for Korean encodings. (stanton) sl@0: sl@0: 12/1/98 (feature change) Changed the Tcl_EvalObjv interface to remove sl@0: the string and length arguments. sl@0: *** POTENTIAL INCOMPATIBILITY with previous alpha releases *** sl@0: sl@0: 12/2/98 (bug fix) Fixed various bugs related to line feed sl@0: translation. [Bug: 887] (stanton) sl@0: sl@0: 12/4/98 (new feature) Added a message catalog facility to help with sl@0: localizing Tcl scripts. Thanks to Mark Harrison for contributing the sl@0: initial implementation of the "msgcat" package. (stanton) sl@0: sl@0: 12/7/98 (bug fix) The memory allocator was failing to update the sl@0: block list for large memory blocks that were reallocated into a sl@0: different address. [Bug: 933] (stanton) sl@0: sl@0: ----------------- Released 8.1b1, Dec 10 1998 ----------------------- sl@0: sl@0: 12/22/98 (performance improvement) Improved the -command option of the sl@0: lsort command to better use the object system for improved sl@0: performance (about 5x speed up). Thanks to Syd Polk for suppling the sl@0: patch. [RFE: 726] (rjohnson) sl@0: sl@0: 2/10/99 (bug fix) Restored the Tcl_ObjSetVar2/Tcl_ObjGetVar2 sl@0: interfaces from 8.0 and renamed the Tcl_GetObjVar2/Tcl_SetObjVar2 sl@0: interfaces to Tcl_GetVar2Ex and Tcl_SetVar2Ex. This should provide sl@0: better compatibility with 8.0. (stanton) sl@0: *** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases *** sl@0: sl@0: 2/10/99 (bug fix) Made the eval interfaces compatible with 8.0 by sl@0: renaming Tcl_EvalObj to Tcl_EvalObjEx, renaming Tcl_Eval2 to sl@0: Tcl_EvalEx and restoring Tcl_EvalObj and Tcl_GlobalEvalObj interfaces sl@0: so they match Tcl 8.0. (stanton) sl@0: *** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases *** sl@0: sl@0: 2/25/99 (bug fix/new feature) On Windows, the channel drivers for sl@0: consoles and serial ports now completely support file events. (redman) sl@0: sl@0: 3/5/99 (bug fix) Integrated patches to fix various configure problems sl@0: that affected HP-UX-11, 64-bit IRIX, Linux, and Solaris. (stanton) sl@0: sl@0: 3/9/99 (bug fix) Integrated various AIX related patches to improve sl@0: support for shared libraries. (stanton) sl@0: sl@0: 3/9/99 (new feature) Added tcl_platform(user) to provide a portable sl@0: way to get the name of the current user. (welch) sl@0: sl@0: 3/9/99 (new feature) Integrated the stub library mechanism contributed sl@0: by Jan Nijtmans, Paul Duffin, and Jean-Claude Wippler. This feature sl@0: should make it possible to write extensions that support multiple sl@0: versions of Tcl simultaneously. It also makes it possible to sl@0: dynamically load extensions into statically linked interpreters. This sl@0: patch includes the following changes: sl@0: - Added a Tcl_InitStubs() interface sl@0: - Added Tcl_PkgProvideEx, Tcl_PkgRequireEx, Tcl_PkgPresentEx, sl@0: and Tcl_PkgPresent. sl@0: - Added va_list versions of all VARARGS functions so they can be sl@0: invoked from wrapper functions. sl@0: See the manual for more information. (stanton) sl@0: sl@0: sl@0: 3/10/99 (feature change) Replaced Tcl_AlertNotifier with sl@0: Tcl_ThreadAlert since the Tcl_AlertNotifier function relied on passing sl@0: internal data structures. (stanton) sl@0: *** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases *** sl@0: sl@0: 3/10/99 (new feature) Added a Tcl_GetVersion API to make it easier to sl@0: check the Tcl version and patch level from C. (redman) sl@0: sl@0: 3/14/99 (feature change) Tried to unify the TclpInitLibrary path sl@0: routines to look in similar places from Windows to UNIX. The new sl@0: library search path is: TCL_LIBRARY, TCL_LIBRARY/../tcl8.1, relative sl@0: to DLL (Windows Only) relative to installed executable, relative to sl@0: develop executable, and relative to compiled-in in location (UNIX sl@0: Only.) This fix included: sl@0: - Defining a TclpFindExecutable sl@0: - Moving Tcl_FindExecutable to a common area in tclEncoding.c sl@0: - Modifying the TclpInitLibraryPath routines. sl@0: (surles) sl@0: sl@0: 3/14/99 (feature change) Added hooks for TclPro Wrapper to initialize sl@0: the location of the encoding files and libraries. This fix included: sl@0: - Adding the TclSetPerInitScript routine. sl@0: - Modifying the Tcl_Init routines to evaluate the non-NULL sl@0: pre-init script. sl@0: - Adding the Tcl_SetdefaultEncodingDir and Tcl_GetDefaultEncodingDir sl@0: routines. sl@0: - Modifying the TclpInitLibrary routines to append the default sl@0: encoding dir. sl@0: (surles) sl@0: sl@0: 3/14/99 (feature change) Test suite now uses "test" namespace to sl@0: define the test procedure and other auxiliary procedures as well as sl@0: global variables. sl@0: - Global array testConfige is now called ::test::testConfig. sl@0: - Global variable VERBOSE is now called ::test::verbose, and sl@0: ::test::verbose no longer works with numerical values. We've sl@0: switched to a bitwise character string. You can set sl@0: ::test::verbose by using the -verbose option on the Tcl command sl@0: line. sl@0: - Global variable TESTS is now called ::test::matchingTests, and sl@0: can be set on the Tcl command line via the -match option. sl@0: - There is now a ::test::skipTests variable (works similarly to sl@0: ::test::matchTests) that can be set on the Tcl command line via sl@0: the -match option. sl@0: - The test suite can now be run in any working directory. When sl@0: you run "make test", the working directory is nolonger switched sl@0: to ../tests. sl@0: (hirschl) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: --------------- Released 8.1b2, March 16, 1999 ---------------------- sl@0: sl@0: 3/18/99 (bug fix) Fixed missing/incorrect characters in shift-jis table sl@0: (stanton) sl@0: sl@0: 3/18/99 (feature change) The glob command ignores the sl@0: FS_CASE_IS_PRESERVED bit on file systesm and always returns sl@0: exactly what it gets from the system. (stanton) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 3/19/99 (new feature) Added support for --enable-64bit. For now, sl@0: this is only supported on Solaris 7 64bit (SunOS 5.7) using the Sun sl@0: compiler. (redman) sl@0: sl@0: 3/23/99 (bug fix) Fixed fileevents and gets on Windows consoles and sl@0: serial devices so that non-blocking channels do not block on partial sl@0: input lines. (redman) sl@0: sl@0: 3/23/99 (bug fix) Added a new Tcl_ServiceModeHook interface. sl@0: This is used on Windows to avoid the various problems that people sl@0: have been seeing where the system hangs when tclsh is running sl@0: outside of the event loop. As part of this, renamed sl@0: TcapAlertNotifier back to Tcl_AlertNotifier since it is public. sl@0: (stanton) sl@0: sl@0: 3/23/99 (feature change) Test suite now uses "tcltest" namespace to sl@0: define the test procedure and other auxiliary procedures as well as sl@0: global variables. The previously chosen "test" namespace was thought sl@0: to be too generic and likely to create conflits. sl@0: (hirschl) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 3/24/99 (bug fix) Make sockets thread safe on Windows. sl@0: (redman) sl@0: sl@0: 3/24/99 (bug fix) Fix cases where expr would incorrect return sl@0: a floating point value instead of an integer. (stanton) sl@0: sl@0: 3/25/99 (bug fix) Added ASCII to big5 and gb2312 encodings. sl@0: (stanton) sl@0: sl@0: 3/25/99 (feature change) Changed so aliases are invoked at current sl@0: scope in the target interpreter instead of at the global scope. This sl@0: was an incompatibility introduced in 8.1 that is being removed. sl@0: (stanton) sl@0: *** POTENTIAL INCOMPATIBILITY with previous beta releases *** sl@0: sl@0: 3/26/99 (feature change) --enable-shared is now the default and build sl@0: Tcl as a shared library; specify --disable-shared to build a static Tcl sl@0: library and shell. sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 3/29/99 (bug fix) Removed the stub functions and changed the stub sl@0: macros to just use the name without params. Pass &tclStubs into the sl@0: interp (don't use tclStubsPtr because of collisions with the stubs on sl@0: Solaris). (redman) sl@0: sl@0: 3/30/99 (bug fix) Loadable modules are now unloaded at the last sl@0: possible moment during Tcl_Finalize to fix various exit-time crashes. sl@0: (welch) sl@0: sl@0: 3/30/99 (bug fix) Tcl no longer calls setlocale(). It looks at sl@0: env(LANG) and env(LC_TYPE) instead. (stanton) sl@0: sl@0: 4/1/99 (bug fix) Fixed the Ultrix multiple symbol definition problem. sl@0: Now, even Tcl includes a copy of the Tcl stub library. (redman) sl@0: sl@0: 4/1/99 (bug fix) Internationalized the registry package. sl@0: sl@0: 4/1/99 (bug fix) Changed the implemenation of Tcl_ConditionWait and sl@0: Tcl_ConditionNotify on Windows. The new algorithm eliminates a race sl@0: condition and was suggested by Jim Davidson. (welch) sl@0: sl@0: 4/2/99 (new apis) Made various Unicode utility functions public. sl@0: Tcl_UtfToUniCharDString, Tcl_UniCharToUtfDString, Tcl_UniCharLen, sl@0: Tcl_UniCharNcmp, Tcl_UniCharIsAlnum, Tcl_UniCharIsAlpha, sl@0: Tcl_UniCharIsDigit, Tcl_UniCharIsLower, Tcl_UniCharIsSpace, sl@0: Tcl_UniCharIsUpper, Tcl_UniCharIsWordChar, Tcl_WinUtfToTChar, sl@0: Tcl_WinTCharToUtf (stanton) sl@0: sl@0: 4/2/99 (feature change) Add new DDE package and removed the Tk sl@0: send command from the Windows version. Changed DDE-based send sl@0: code into "dde eval" command. The DDE package can be loaded sl@0: into tclsh, not just wish. Windows only. (redman) sl@0: sl@0: 4/5/99 (bug fix) Changed safe-tcl so that the encoding command sl@0: is an alias that masks out the "encoding system" subcommand. sl@0: (redman) sl@0: sl@0: 4/5/99 (bug fix) Configure patches to improve support for sl@0: OS/390 and BSD/OS 4.*. (stanton) sl@0: sl@0: 4/5/99 (bug fix) Fixed crash in the clock command that occurred sl@0: with negative time values in timezones east of GMT. (stanton) sl@0: sl@0: 4/6/99 (bug fix) Moved the "array set" C level code into a common sl@0: routine (TclArraySet). The TclSetupEnv routine now uses this API to sl@0: create an env array w/ no elements. This fixes the bug caused when sl@0: every environ varaible is removed, and the Tcl env variable is sl@0: synched. If no environ vars existed, the Tcl env var would never be sl@0: created. (surles) sl@0: sl@0: 4/6/99 (bug fix) Made the Env module I18N compliant. (surles) sl@0: sl@0: 4/6/99 (bug fix) Changed the FindVariable routine to TclpFindVariable, sl@0: that now does a case insensitive string comparison on Windows, and not sl@0: on UNIX. (surles) sl@0: sl@0: --------------- Released 8.1b3, April 6, 1999 ---------------------- sl@0: sl@0: 4/9/99 (bug fix) Fixed notifier deadlock situation when the pipe used sl@0: to talk back notifier thread is filled with data. Found as a result of the sl@0: focus.test for Tk hanging. (redman) sl@0: sl@0: 4/13/99 (bug fix) Fixed bug where socket -async combined with sl@0: fileevent for writing did not work under Windows NT. (redman) sl@0: sl@0: 4/13/99 (encoding fix) Restored the double byte definition of GB2312 sl@0: and added the EUC-CN encoding. EUC-CN is a variant of GB2312 that sl@0: shifts the characters into bytes with the high bit set and includes sl@0: ASCII as a subset. (stanton) sl@0: sl@0: 4/27/99 (bug fix) Added 'extern "C" {}' block around the stub table sl@0: pointer declaration so the stub library can be used from C++. (stanton) sl@0: sl@0: --------------- Released 8.1 final, April 29, 1999 ---------------------- sl@0: sl@0: 4/22/99 (bug fix) Changed Windows NT socket implementation to avoid sl@0: creating a communication window. This avoids the problem where the sl@0: system hangs waiting for tclsh to respond to a system-wide synchronous sl@0: broadcast (e.g. if you change system colors). (redman) sl@0: sl@0: 4/22/99 (bug fix) Added call to TclWinInit from TclpInitPlatform when sl@0: building a static library since DllMain will not be invoked. This sl@0: could break old code that explicitly called TclWinInit, but should be sl@0: simpler in the long run. (stanton) sl@0: *** POTENTIAL INCOMPATIBILITY *** sl@0: sl@0: 4/23/99 (bug fix) Added support for the koi8-r Cyrillic sl@0: encoding. [Bug: 1771] (stanton) sl@0: sl@0: 4/28/99 (bug fix) Changed internal Tcl_Obj usage to avoid freeing the sl@0: internal representation after the string representation has been sl@0: freed. This makes it easier to debug extensions. (stanton) sl@0: sl@0: 4/30/99 (bug fix) Fixed a memory leak in CommandComplete. (stanton) sl@0: sl@0: 5/3/99 (bug fix) Fixed a bug where the Tcl_ObjType was not being set sl@0: in a duplicated Tcl_Obj. [Bug: 1975, 2047] (stanton) sl@0: sl@0: 5/3/99 (bug fix) Changed Tcl_ParseCommand to avoid modifying eval'ed sl@0: strings that are already null terminated. [Bug: 1793] (stanton) sl@0: sl@0: 5/3/99 (new feature) Applied Jeff Hobbs's string patch which includes sl@0: the following changes: sl@0: - added new subcommands: equal, repeat, map, is, replace sl@0: - added -length option to "string compare|equal" sl@0: - added -nocase option to "string compare|equal|match" sl@0: - string and list indices can be an integer or end?-integer?. sl@0: - added optional first and last index args to string toupper, et al. sl@0: See the string.n manual entry for more details about the new string sl@0: features. [Bug: 1845] (stanton) sl@0: sl@0: 5/6/99 (new feature) Added Tcl_UtfNcmp and Tcl_UtfNcasecmp to make Utf sl@0: string comparision easier. (stanton) sl@0: sl@0: 5/7/99 (bug fix) Improved OS/390 support. [Bug: 1976, 1997] (stanton) sl@0: sl@0: 5/12/99 (bug fix) Changed Windows initialization code to avoid using sl@0: GetUserName system call in favor of the env(USERNAME) variable. This sl@0: provides a significant startup speed improvement. (stanton) sl@0: sl@0: 5/12/99 (bug fix) Replaced the per-interpreter regexp cache with a sl@0: per-thread cache. Changed the Regexp object to take advantage of this sl@0: extra cache. Added a reference count to the TclRegexp type so regexps sl@0: can be shared by multiple objects. Removed the per-interp regexp cache sl@0: from the interpreter. Now regexps can be used with no need for an sl@0: interpreter. This set of changes should provide significant speed sl@0: improvements for many Tcl scripts. [Bug: 1063] (stanton) sl@0: sl@0: 5/14/99 (bug fix) Durining initialization on Unix, Tcl now extracts the sl@0: encoding subfield from the LANG/LC_ALL environment variables in cases sl@0: where the locale is not found in the built-in locale table. It also sl@0: attempts to initialize the locale subsystem so X11 is happy. [Bug: 1989] sl@0: (stanton) sl@0: sl@0: 5/14/99 (bug fix) Applied the patch to fix 100-year and 400-year sl@0: boundaries in leap year code, from Isaac Hollander.

(stanton) sl@0: sl@0: 5/18/99 (bug fix) Modified initialization code on Windows to avoid sl@0: inherenting closed or invalid channels. If the standard input is sl@0: anything other than a console, file, serial port, or pipe, then we fall sl@0: back to the standard Tk window console. (stanton) sl@0: sl@0: 5/19/99 (bug fix) Added an extern "C" block around the entire tcl.h sl@0: header file to avoid C++ linkage issues. (redman) sl@0: sl@0: 5/19/99 (new feature) Applied Jeff Hobb's patch to add sl@0: Tcl_StringCaseMatch to support case insensitive glob style matching and sl@0: Tcl_UniCharIs* character classification functions. (stanton) sl@0: sl@0: 5/20/99 (bug fix) Added the directory containing the executuble and the sl@0: ../lib directory relative to that to the auto_path variable.

(stanton) sl@0: sl@0: 6/9/99 (new feature) Added Tcl_RegExpMatchObj and Tcl_RegExpGetInfo sl@0: to public Tcl API, these functions are needed by Expect. Changed sl@0: tools/genStubs.tcl to always write output in LF mode. (stanton) sl@0: sl@0: 6/14/99 (new feature) Merged string and Unicode object types. Added sl@0: new public Tcl API functions: Tcl_NewUnicodeObj, Tcl_SetUnicodeObj, sl@0: Tcl_GetUnicode, Tcl_GetUniChar, Tcl_GetCharLength, Tcl_GetRange, sl@0: Tcl_AppendUnicodeToObj. (hershey) sl@0: sl@0: 6/16/99 (new feature) Changed to conform to TEA specification, added sl@0: tcl.m4 and aclocal.m4 macro libraries for configure. (wart) sl@0: sl@0: 6/17/99 (new feature) Added new regexp interfaces: -expanded, -line, sl@0: -linestop, and -lineanchor switches. Renamed Tcl_RegExpMatchObj to sl@0: Tcl_RegExpExecObj and added new Tcl_RegExpMatchObj that is equivalent sl@0: to Tcl_RegExpMatch. Added public macros for regexp flags. Added sl@0: REG_BOSONLY flag to allow Expect to iterate through a string and only sl@0: find matches that start at the current position within the sl@0: string. (stanton) sl@0: sl@0: 6/21/99 (bug fix) Fixed memory leak in TclpThreadCreate where thread sl@0: attributes were not being released. [Bug: 2254] (stanton) sl@0: sl@0: 6/23/99 (new feature) Updated Unicode character tables to reflect sl@0: Unicode 2.1 data. (stanton) sl@0: sl@0: 6/25/99 (new feature) Fixed bugs in non-greedy quantifiers for regular sl@0: expression code. (stanton) sl@0: sl@0: 6/25/99 (new feature) Added initial implementation of new Tcl test sl@0: harness package. Modified test files to use new tcltest package. sl@0: (jenn) sl@0: sl@0: 6/26/99 (new feature) Applied patch from Peter Hardie to add poke sl@0: command to dde and changed the dde package version number to sl@0: 1.1. (redman) sl@0: sl@0: 6/28/99 (bug fix) Applied patch from Peter Hardie to fix problem in sl@0: Tcl_GetIndexFromObj() when the key being passed is the empty string. sl@0: [Bug: 1738] (redman) sl@0: sl@0: 6/29/99 (new feature) Added options to tcltest package: -preservecore, sl@0: -limitconstraints, -help, -file, -notfile, and flags. (jenn) sl@0: sl@0: 7/3/99 (new feature) Changed parsing of variable names to allow empty sl@0: array names. Now "$(foo)" is a variable reference. Previously you sl@0: had to use something line $::(foo), which is slower. This change was sl@0: requested by Jean-Luc Fontaine for his STOOOP package. (welch) sl@0: sl@0: 7/3/99 (new feature) Added Tcl_SetNotifier (public API) and sl@0: associated hook points in the notifiers to be able to replace the sl@0: notifier calls at runtime. The Xt notifier and test program use this sl@0: hook. (welch) sl@0: sl@0: 7/3/99 (new feature) Added a new variant of the "Trf core patch" from sl@0: Andreas Kupries that adds new C APIs Tcl_StackChannel, sl@0: Tcl_UnstackChannel, and Tcl_GetStackedChannel. This allows the Trf sl@0: extension to work without applying patches to the Tcl core. (welch) sl@0: sl@0: 7/6/99 (new feature) Added -timeout option to http.tcl to handle sl@0: timeouts that occur during connection attempts to hosts that are sl@0: down. (welch) sl@0: sl@0: 7/6/99 (bug fix) Applied new implementation of the Windows serial sl@0: port driver from Rolf Schroedter that fixes reading only one byte from sl@0: the port at a time.

These APIs are all for sl@0: the mutex used in the simple memory allocators. By making this change sl@0: we are able to substitute different implementations of the thread-related sl@0: APIs without having to recompile the Tcl core. (welch) sl@0: sl@0: 8/9/99 (new C API) Tcl_GetChannelNames returns a list of open channel sl@0: names in the interpreter result. Still no Tcl-level version of this, sl@0: but server-like applications can use this to clean up files without sl@0: deleting interpreters. (welch) sl@0: sl@0: 8/9/99 (bug fix) Traces were not firing on "info exists", which used to sl@0: happen in Tcl 7.6 and earlier. An "info exists" now fires a read trace, sl@0: if defined. This makes it possible to fully implement variables that sl@0: are defined via traces. (welch) sl@0: sl@0: 8/10/99 (bug fix) Fixed Brent's changes so that they work on sl@0: Windows. (redman) sl@0: sl@0: --------------- Released 8.2b3, August 11, 1999 ---------------------- sl@0: sl@0: 8/12/99 (Mac) Rearrange projects in tclMacProjects.sea.hqx so that the sl@0: build directory is separate from the sources.
