1.4 +Recent user-visible changes to Tcl:
1.5 +
1.6 +RCS: @(#) $Id: changes,v 1.79.2.50 2007/05/16 22:13:07 das Exp $
1.7 +
1.8 +1. No more [command1] [command2] construct for grouping multiple
1.9 +commands on a single command line.
1.10 +
1.11 +2. Semi-colon now available for grouping commands on a line.
1.12 +
1.13 +3. For a command to span multiple lines, must now use backslash-return
1.14 +at the end of each line but the last.
1.15 +
1.16 +4. "Var" command has been changed to "set".
1.17 +
1.18 +5. Double-quotes now available as an argument grouping character.
1.19 +
1.20 +6. "Return" may be used at top-level.
1.21 +
1.22 +7. More backslash sequences available now. In particular, backslash-newline
1.23 +may be used to join lines in command files.
1.24 +
1.25 +8. New or modified built-in commands: case, return, for, glob, info,
1.26 +print, return, set, source, string, uplevel.
1.27 +
1.28 +9. After an error, the variable "errorInfo" is filled with a stack
1.29 +trace showing what was being executed when the error occurred.
1.30 +
1.31 +10. Command abbreviations are accepted when parsing commands, but
1.32 +are not recommended except for purely-interactive commands.
1.33 +
1.34 +11. $, set, and expr all complain now if a non-existent variable is
1.35 +referenced.
1.36 +
1.37 +12. History facilities exist now. See Tcl.man and Tcl_RecordAndEval.man.
1.38 +
1.39 +13. Changed to distinguish between empty variables and those that don't
1.40 +exist at all. Interfaces to Tcl_GetVar and Tcl_ParseVar have changed
1.41 +(NULL return value is now possible). *** POTENTIAL INCOMPATIBILITY ***
1.42 +
1.43 +14. Changed meaning of "level" argument to "uplevel" command (1 now means
1.44 +"go up one level", not "go to level 1"; "#1" means "go to level 1").
1.45 +*** POTENTIAL INCOMPATIBILITY ***
1.46 +
1.47 +15. 3/19/90 Added "info exists" option to see if variable exists.
1.48 +
1.49 +16. 3/19/90 Added "noAbbrev" variable to prohibit command abbreviations.
1.50 +
1.51 +17. 3/19/90 Added extra errorInfo option to "error" command.
1.52 +
1.53 +18. 3/21/90 Double-quotes now only affect space: command, variable,
1.54 +and backslash substitutions still occur inside double-quotes.
1.55 +*** POTENTIAL INCOMPATIBILITY ***
1.56 +
1.57 +19. 3/21/90 Added support for \r.
1.58 +
1.59 +20. 3/21/90 List, concat, eval, and glob commands all expect at least
1.60 +one argument now. *** POTENTIAL INCOMPATIBILITY ***
1.61 +
1.62 +21. 3/22/90 Added "?:" operators to expressions.
1.63 +
1.64 +22. 3/25/90 Fixed bug in Tcl_Result that caused memory to get trashed.
1.65 +
1.66 +------------------- Released version 3.1 ---------------------
1.67 +
1.68 +23. 3/29/90 Fixed bug that caused "file a.b/c ext" to return ".b/c".
1.69 +
1.70 +24. 3/29/90 Semi-colon is not treated specially when enclosed in
1.71 +double-quotes.
1.72 +
1.73 +------------------- Released version 3.2 ---------------------
1.74 +
1.75 +25. 4/16/90 Rewrote "exec" not to use select or signals anymore.
1.76 +Should be more Sys-V compatible, and no slower in the normal case.
1.77 +
1.78 +26. 4/18/90 Rewrote "glob" to eliminate GNU code (there's no GNU code
1.79 +left in Tcl, now), and added Tcl_TildeSubst procedure. Added automatic
1.80 +tilde-substitution in many commands, including "glob".
1.81 +
1.82 +------------------- Released version 3.3 ---------------------
1.83 +
1.84 +27. 7/11/90 Added "Tcl_AppendResult" procedure.
1.85 +
1.86 +28. 7/20/90 "History" with no options now defaults to "history info"
1.87 +rather than to "history redo". Although this is a backward incompatibility,
1.88 +it should only be used interactively and thus shouldn't present any
1.89 +compatibility problems with scripts.
1.90 +
1.91 +29. 7/20/90 Added "Tcl_GetInteger", "Tcl_GetDouble", and "Tcl_GetBoolean"
1.92 +procedures.
1.93 +
1.94 +30. 7/22/90 Removed "Tcl_WatchInterp" procedure: doesn't seem to be
1.95 +necessary, since the same effect can be achieved with the deletion
1.96 +callbacks on individual commands. *** POTENTIAL INCOMPATIBILITY ***
1.97 +
1.98 +31. 7/23/90 Added variable tracing: Tcl_TraceVar, Tcl_UnTraceVar,
1.99 +and Tcl_VarTraceInfo procedures, "trace" command.
1.100 +
1.101 +32. 8/9/90 Mailed out list of all bug fixes since 3.3 release.
1.102 +
1.103 +33. 8/29/90 Fixed bugs in Tcl_Merge relating to backslashes and
1.104 +semi-colons. Mailed out patch.
1.105 +
1.106 +34. 9/3/90 Fixed bug in tclBasic.c: quotes weren't quoting ]'s.
1.107 +Mailed out patch.
1.108 +
1.109 +35. 9/19/90 Rewrote exec to always use files both for input and
1.110 +output to the process. The old pipe-based version didn't work if
1.111 +the exec'ed process forked a child and then exited: Tcl waited
1.112 +around for stdout to get closed, which didn't happen until the
1.113 +grandchild exited.
1.114 +
1.115 +36. 11/5/90 ERR_IN_PROGRESS flag wasn't being cleared soon enough
1.116 +in Tcl_Eval, allowing error messages from different commands to
1.117 +pile up in $errorInfo. Fixed by re-arranging code in Tcl_Eval that
1.118 +re-initializes result and ERR_IN_PROGRESS flag. Didn't mail out
1.119 +patch: changes too complicated to describe.
1.120 +
1.121 +37. 12/19/90 Added Tcl_VarEval procedure as a convenience for
1.122 +assembling and executing Tcl commands.
1.123 +
1.124 +38. 1/29/91 Fixed core leak in Tcl_AddErrorInfo. Also changed procedure
1.125 +and Tcl_Eval so that first call to Tcl_AddErrorInfo need not come from
1.126 +Tcl_Eval.
1.127 +
1.128 +----------------- Released version 5.0 with Tk ------------------
1.129 +
1.130 +39. 4/3/91 Removed change bars from manual entries, leaving only those
1.131 +that came after version 3.3 was released.
1.132 +
1.133 +40. 5/17/91 Changed tests to conform to Mary Ann May-Pumphrey's approach.
1.134 +
1.135 +41. 5/23/91 Massive revision to Tcl parser to simplify the implementation
1.136 +of string and floating-point support in expressions. Newlines inside
1.137 +[] are now treated as command separators rather than word separators
1.138 +(this makes newline treatment consistent throughout Tcl).
1.139 +*** POTENTIAL INCOMPATIBILITY ***
1.140 +
1.141 +42. 5/23/91 Massive rewrite of expression code to support floating-point
1.142 +values and simple string comparisons. The C interfaces to expression
1.143 +routines have changed (Tcl_Expr is replaced by Tcl_ExprLong, Tcl_ExprDouble,
1.144 +etc.), but all old Tcl expression strings should be accepted by the new
1.145 +expression code.
1.146 +*** POTENTIAL INCOMPATIBILITY ***
1.147 +
1.148 +43. 5/23/91 Modified tclHistory.c to check for negative "keep" value.
1.149 +
1.150 +44. 5/23/91 Modified Tcl_Backslash to handle backslash-newline. It now
1.151 +returns 0 to indicate that a backslash sequence should be replaced by
1.152 +no character at all.
1.153 +*** POTENTIAL INCOMPATIBILITY ***
1.154 +
1.155 +45. 5/29/91 Modified to use ANSI C function prototypes. Must set
1.156 +"USE_ANSI" switch when compiling to get prototypes.
1.157 +
1.158 +46. 5/29/91 Completed test suite by providing tests for all of the
1.159 +built-in Tcl commands.
1.160 +
1.161 +47. 5/29/91 Changed Tcl_Concat to eliminate leading and trailing
1.162 +white-space in each of the things it concatenates and to ignore
1.163 +elements that are empty or have only white space in them. This
1.164 +produces cleaner output from the "concat" command.
1.165 +*** POTENTIAL INCOMPATIBILITY ***
1.166 +
1.167 +48. 5/31/91 Changed "set" command and Tcl_SetVar procedure to return
1.168 +new value of variable.
1.169 +
1.170 +49. 6/1/91 Added "while" and "cd" commands.
1.171 +
1.172 +50. 6/1/91 Changed "exec" to delete the last character of program
1.173 +output if it is a newline. In most cases this makes it easier to
1.174 +process program-generated output.
1.175 +*** POTENTIAL INCOMPATIBILITY ***
1.176 +
1.177 +51. 6/1/91 Made sure that pointers are never used after freeing them.
1.178 +
1.179 +52. 6/1/91 Fixed bug in TclWordEnd where it wasn't dealing with
1.180 +[] inside quotes correctly.
1.181 +
1.182 +53. 6/8/91 Fixed exec.test to accept return values of either 1 or
1.183 +255 from "false" command.
1.184 +
1.185 +54. 7/6/91 Massive overhaul of variable management. Associative
1.186 +arrays now available, along with "unset" command (and Tcl_UnsetVar
1.187 +procedure). Variable traces have been completely reworked:
1.188 +interfaces different both from Tcl and C, and multiple traces may
1.189 +exist on same variable. Can no longer redefine existing local
1.190 +variable to be global. Calling sequences have changed slightly
1.191 +for Tcl_GetVar and Tcl_SetVar ("global" is now "flags"). Tcl_SetVar
1.192 +can fail and return a NULL result. New forms of variable-manipulation
1.193 +procedures: Tcl_GetVar2, Tcl_SetVar2, etc. Syntax of variable
1.194 +$-notation changed to support array indexing.
1.195 +*** POTENTIAL INCOMPATIBILITY ***
1.196 +
1.197 +55. 7/6/91 Added new list-manipulation procedures: Tcl_ScanElement,
1.198 +Tcl_ConvertElement, Tcl_AppendElement.
1.199 +
1.200 +56. 7/12/91 Created new procedure Tcl_EvalFile, which does most of the
1.201 +work of the "source" command.
1.202 +
1.203 +57. 7/20/91 Major reworking of "exec" command to allow pipelines,
1.204 +more redirection, background. Added new procedures Tcl_Fork,
1.205 +Tcl_WaitPids, Tcl_DetachPids, and Tcl_CreatePipeline. The old
1.206 +"< input" notation has been replaced by "<< input" ("<" is for
1.207 +redirection from a file). Also handles error returns and abnormal
1.208 +terminations (e.g. signals) differently.
1.209 +*** POTENTIAL INCOMPATIBILITY ***
1.210 +
1.211 +58. 7/21/91 Added "append" and "lappend" commands.
1.212 +
1.213 +59. 7/22/91 Reworked error messages and manual entries to use
1.214 +?x? as the notation for an optional argument x, instead of [x]. The
1.215 +bracket notation was often confused with the use of brackets for
1.216 +command substitution. Also modified error messages to be more
1.217 +consistent.
1.218 +
1.219 +60. 7/23/91 Tcl_DeleteCommand now returns an indication of whether
1.220 +or not the command actually existed, and the "rename" command uses
1.221 +this information to return an error if an attempt is made to delete
1.222 +a non-existent command.
1.223 +*** POTENTIAL INCOMPATIBILITY ***
1.224 +
1.225 +61. 7/25/91 Added new "errorCode" mechanism, along with procedures
1.226 +Tcl_SetErrorCode, Tcl_UnixError, and Tcl_ResetResult. Renamed
1.227 +Tcl_Return to Tcl_SetResult, but left a #define for Tcl_Return to
1.228 +avoid compatibility problems.
1.229 +
1.230 +62. 7/26/91 Extended "case" command with alternate syntax where all
1.231 +patterns and commands are together in a single list argument: makes
1.232 +it easier to write multi-line case statements.
1.233 +
1.234 +63. 7/27/91 Changed "print" command to perform tilde-substitution on
1.235 +the file name.
1.236 +
1.237 +64. 7/27/91 Added "tolower", "toupper", "trim", "trimleft", and "trimright"
1.238 +options to "string" command.
1.239 +
1.240 +65. 7/29/91 Added "atime", "mtime", "size", and "stat" options to "file"
1.241 +command.
1.242 +
1.243 +66. 8/1/91 Added "split" and "join" commands.
1.244 +
1.245 +67. 8/11/91 Added commands for file I/O, including "open", "close",
1.246 +"read", "gets", "puts", "flush", "eof", "seek", and "tell".
1.247 +
1.248 +68. 8/14/91 Switched to use a hash table for command lookups. Command
1.249 +abbreviations no longer have direct support in the Tcl interpreter, but
1.250 +it should be possible to simulate them with the auto-load features
1.251 +described below. The "noAbbrev" variable is no longer used by Tcl.
1.252 +*** POTENTIAL INCOMPATIBILITY ***
1.253 +
1.254 +68.5 8/15/91 Added support for "unknown" command, which can be used to
1.255 +complete abbreviations, auto-load library files, auto-exec shell
1.256 +commands, etc.
1.257 +
1.258 +69. 8/15/91 Added -nocomplain switch to "glob" command.
1.259 +
1.260 +70. 8/20/91 Added "info library" option and TCL_LIBRARY #define. Also
1.261 +added "info script" option.
1.262 +
1.263 +71. 8/20/91 Changed "file" command to take "option" argument as first
1.264 +argument (before file name), for consistency with other Tcl commands.
1.265 +*** POTENTIAL INCOMPATIBILITY ***
1.266 +
1.267 +72. 8/20/91 Changed format of information in $errorInfo variable:
1.268 +comments such as
1.269 + ("while" body line 1)
1.270 +are now on separate lines from commands being executed.
1.271 +*** POTENTIAL INCOMPATIBILITY ***
1.272 +
1.273 +73. 8/20/91 Changed Tcl_AppendResult so that it (eventually) frees
1.274 +large buffers that it allocates.
1.275 +
1.276 +74. 8/21/91 Added "linsert", "lreplace", "lsearch", and "lsort"
1.277 +commands.
1.278 +
1.279 +75. 8/28/91 Added "incr" and "exit" commands.
1.280 +
1.281 +76. 8/30/91 Added "regexp" and "regsub" commands.
1.282 +
1.283 +77. 9/4/91 Changed "dynamic" field in interpreters to "freeProc" (procedure
1.284 +address). This allows for alternative storage managers.
1.285 +*** POTENTIAL INCOMPATIBILITY ***
1.286 +
1.287 +78. 9/6/91 Added "index", "length", and "range" options to "string"
1.288 +command. Added "lindex", "llength", and "lrange" commands.
1.289 +
1.290 +79. 9/8/91 Removed "index", "length", "print" and "range" commands.
1.291 +"Print" is redundant with "puts", but less general, and the other
1.292 +commands are replaced with the new commands described in change 78
1.293 +above.
1.294 +*** POTENTIAL INCOMPATIBILITY ***
1.295 +
1.296 +80. 9/8/91 Changed history revision to occur even when history command
1.297 +is nested; needed in order to allow "history" to be invoked from
1.298 +"unknown" procedure.
1.299 +
1.300 +81. 9/13/91 Changed "panic" not to use vfprintf (it's uglier and less
1.301 +general now, but makes it easier to run Tcl on systems that don't
1.302 +have vfprintf). Also changed "strerror" not to redeclare sys_errlist.
1.303 +
1.304 +82. 9/19/91 Lots of changes to improve portability to different UNIX
1.305 +systems, including addition of "config" script to adapt Tcl to the
1.306 +configuration of the system it's being compiled on.
1.307 +
1.308 +83. 9/22/91 Added "pwd" command.
1.309 +
1.310 +84. 9/22/91 Renamed manual pages so that their filenames are no more
1.311 +than 14 characters in length, moved to "doc" subdirectory.
1.312 +
1.313 +85. 9/24/91 Redid manual entries so they contain the supplemental
1.314 +macros that they need; can just print with "troff -man" or "man"
1.315 +now.
1.316 +
1.317 +86. 9/26/91 Created initial version of script library, including
1.318 +a version of "unknown" that does auto-loading, auto-execution, and
1.319 +abbreviation expansion. This library is used by tclTest
1.320 +automatically. See the "library" manual entry for details.
1.321 +
1.322 +----------------- Released version 6.0, 9/26/91 ------------------
1.323 +
1.324 +87. 9/30/91 Made "string tolower" and "string toupper" check case
1.325 +before converting: on some systems, "tolower" and "toupper" assume
1.326 +that character already has particular case.
1.327 +
1.328 +88. 9/30/91 Fixed bug in Tcl_SetResult: wasn't always setting freeProc
1.329 +correctly when called with NULL value. This tended to cause memory
1.330 +allocation errors later.
1.331 +
1.332 +89. 10/3/91 Added "upvar" command.
1.333 +
1.334 +90. 10/4/91 Changed "format" so that internally it converts %D to %ld,
1.335 +%U to %lu, %O to %lo, and %F to %f. This eliminates some compatibility
1.336 +problems on some machines without affecting behavior.
1.337 +
1.338 +91. 10/10/91 Fixed bug in "regsub" that caused core dumps with the -all
1.339 +option when the last match wasn't at the end of the string.
1.340 +
1.341 +92. 10/17/91 Fixed problems with backslash sequences: \r support was
1.342 +incomplete and \f and \v weren't supported at all.
1.343 +
1.344 +93. 10/24/91 Added Tcl_InitHistory procedure.
1.345 +
1.346 +94. 10/24/91 Changed "regexp" to store "-1 -1" in subMatchVars that
1.347 +don't match, rather than returning an error.
1.348 +
1.349 +95. 10/27/91 Modified "regexp" to return actual strings in matchVar
1.350 +and subMatchVars instead of indices. Added "-indices" switch to cause
1.351 +indices to be returned.
1.352 +*** POTENTIAL INCOMPATIBILITY ***
1.353 +
1.354 +96. 10/27/91 Fixed bug in "scan" where it used hardwired constants for
1.355 +sizes of floats and doubles instead of using "sizeof".
1.356 +
1.357 +97. 10/31/91 Fixed bug in tclParse.c where parse-related error messages
1.358 +weren't being storage-managed correctly, causing spurious free's.
1.359 +
1.360 +98. 10/31/91 Form feed and vertical tab characters are now considered
1.361 +to be space characters by the parser.
1.362 +
1.363 +99. 10/31/91 Added TCL_LEAVE_ERR_MSG flag to procedures like Tcl_SetVar.
1.364 +
1.365 +100. 11/7/91 Fixed bug in "case" where "in" argument couldn't be omitted
1.366 +if all case branches were embedded in a single list.
1.367 +
1.368 +101. 11/7/91 Switched to use "pid_t" and "uid_t" and other official
1.369 +POSIC types and function prototypes.
1.370 +
1.371 +----------------- Released version 6.1, 11/7/91 ------------------
1.372 +
1.373 +102. 12/2/91 Modified Tcl_ScanElement and Tcl_ConvertElement in several
1.374 +ways. First, allowed caller to request that only backslashes be used
1.375 +(no braces). Second, made Tcl_ConvertElement more aggressive in using
1.376 +backslashes for braces and quotes.
1.377 +
1.378 +103. 12/5/91 Added "type", "lstat", and "readlink" options to "file"
1.379 +command, plus added new "type" element to output of "stat" and "lstat"
1.380 +options.
1.381 +
1.382 +104. 12/10/91 Manual entries had first lines that caused "man" program
1.383 +to try weird preprocessor. Added blank comment lines to fix problem.
1.384 +
1.385 +105. 12/16/91 Fixed a few bugs in auto_mkindex proc: wasn't handling
1.386 +errors properly, and hadn't been upgraded for new "regexp" syntax.
1.387 +
1.388 +106. 1/2/92 Fixed bug in "file" command where it didn't properly handle
1.389 +a file names containing tildes where the indicated user doesn't exist.
1.390 +
1.391 +107. 1/2/92 Fixed lots of cases in tclUnixStr.c where two different
1.392 +errno symbols (e.g. EWOULDBLOCK and EAGAIN) have the same number; Tcl
1.393 +will only use one of them.
1.394 +
1.395 +108. 1/2/92 Lots of changes to configuration script to handle many more
1.396 +systems more gracefully. E.g. should now detect the bogus strtoul that
1.397 +comes with AIX and substitute Tcl's own version instead.
1.398 +
1.399 +----------------- Released version 6.2, 1/10/92 ------------------
1.400 +
1.401 +109. 1/20/92 Config didn't have code to actually use "uid_t" variable
1.402 +to set TCL_UIT_T #define.
1.403 +
1.404 +110. 2/10/92 Tcl_Eval didn't properly reset "numLevels" variable when
1.405 +too-deep recursion occurred.
1.406 +
1.407 +111. 2/29/92 Added "on" and "off" to keywords accepted by Tcl_GetBoolean.
1.408 +
1.409 +112. 3/19/92 Config wasn't installing default version of strtod.c for
1.410 +systems that don't have one in libc.a.
1.411 +
1.412 +113. 3/23/92 Fixed bug in tclExpr.c where numbers with leading "."s,
1.413 +like 0.75, couldn't be properly substituted into expressions with
1.414 +variable or command substitution.
1.415 +
1.416 +114. 3/25/92 Fixed bug in tclUnixAZ.c where "gets" command wasn't
1.417 +checking to make sure that it was able to write the variable OK.
1.418 +
1.419 +115. 4/16/92 Fixed bug in tclUnixAZ.c where "read" command didn't
1.420 +compute file size right for device files.
1.421 +
1.422 +116. 4/23/92 Fixed but in tclCmdMZ.c where "trace vinfo" was overwriting
1.423 +the trace command.
1.424 +
1.425 +----------------- Released version 6.3, 5/1/92 ------------------
1.426 +
1.427 +117. 5/1/92 Added Tcl_GlobalEval.
1.428 +
1.429 +118. 6/1/92 Changed auto-load facility to source files at global level.
1.430 +
1.431 +119. 6/8/92 Tcl_ParseVar wasn't always setting termPtr after errors, which
1.432 +sometimes caused core dumps.
1.433 +
1.434 +120. 6/21/92 Fixed bug in initialization of regexp pattern cache. This
1.435 +bug caused segmentation violations in regexp commands under some conditions.
1.436 +
1.437 +121. 6/22/92 Changed implementation of "glob" command to eliminate
1.438 +trailing slashes on directory names: they confuse some systems. There
1.439 +shouldn't be any user-visible changes in functionality except for names
1.440 +in error messages not having trailing slashes.
1.441 +
1.442 +122. 7/2/92 Fixed bug that caused 'string match ** ""' to return 0.
1.443 +
1.444 +123. 7/2/92 Fixed bug in Tcl_CreateCmdBuf where it wasn't initializing
1.445 +the buffer to an empty string.
1.446 +
1.447 +124. 7/6/92 Fixed bug in "case" command where it used NULL pattern string
1.448 +after errors in the "default" clause.
1.449 +
1.450 +125. 7/25/92 Speeded up auto_load procedure: don't reread all the index
1.451 +files unless the path has changed.
1.452 +
1.453 +126. 8/3/92 Changed tclUnix.h to define MAXPATHLEN from PATH_MAX, not
1.454 +_POSIX_PATH_MAX.
1.455 +
1.456 +----------------- Released version 6.4, 8/7/92 ------------------
1.457 +
1.458 +127. 8/10/92 Changed tclBasic.c so that comment lines can be continued by
1.459 +putting a backslash before the newline.
1.460 +
1.461 +128. 8/21/92 Modified "unknown" to allow the source-ing of a file for
1.462 +an auto-load to trigger other nested auto-loads, as long as there isn't
1.463 +any recursion on the same command name.
1.464 +
1.465 +129. 8/25/92 Modified "format" command to allow " " and "+" flags, and
1.466 +allow flags in any order.
1.467 +
1.468 +130. 9/14/92 Modified Tcl_ParseVar so that it doesn't actually attempt
1.469 +to look up the variable if "noEval" mode is in effect in the interpreter
1.470 +(it just parses the name). This avoids the errors that used to occur
1.471 +in statements like "expr {[info exists foo] && $foo}".
1.472 +
1.473 +131. 9/14/92 Fixed bug in "uplevel" command where it didn't output the
1.474 +correct error message if a level was specified but no command.
1.475 +
1.476 +132. 9/14/92 Renamed manual entries to have extensions like .3 and .n,
1.477 +and added "install" target to Makefile.
1.478 +
1.479 +133. 9/18/92 Modified "unknown" command to emulate !!, !<num>, and
1.480 +^<old>^<new> csh history substitutions.
1.481 +
1.482 +134. 9/21/92 Made the config script cleverer about figuring out which
1.483 +switches to pass to "nm".
1.484 +
1.485 +135. 9/23/92 Fixed tclVar.c to be sure to copy flags when growing variables.
1.486 +Used to forget about traces in progress and make extra recursive calls
1.487 +on trace procs.
1.488 +
1.489 +136. 9/28/92 Fixed bug in auto_reset where it was unsetting variables
1.490 +that might not exist.
1.491 +
1.492 +137. 10/7/92 Changed "parray" library procedure to print any array
1.493 +accessible to caller, local or global.
1.494 +
1.495 +138. 10/15/92 Fixed bug where propagation of new environment variable
1.496 +values among interpreters took N! time if there exist N interpreters.
1.497 +
1.498 +139. 10/16/92 Changed auto_reset procedure so that it also deletes any
1.499 +existing procedures that are in the auto_load index (the assumption is
1.500 +that they should be re-loaded to get the latest versions).
1.501 +
1.502 +140. 10/21/92 Fixed bug that caused lists to be incorrectly generated
1.503 +for elements that contained backslash-newline sequences.
1.504 +
1.505 +141. 12/9/92 Added support for TCL_LIBRARY environment variable: use
1.506 +it as library location if it's present.
1.507 +
1.508 +142. 12/9/92 Added "info complete" command, Tcl_CommandComplete procedure.
1.509 +
1.510 +143. 12/16/92 Changed the Makefile to check to make sure "config" has been
1.511 +run (can't run config directly from the Makefile because it modifies the
1.512 +Makefile; thus make has to be run again after running config).
1.513 +
1.514 +----------------- Released version 6.5, 12/17/92 ------------------
1.515 +
1.516 +144. 12/21/92 Changed config to look in several places for libc file.
1.517 +
1.518 +145. 12/23/92 Added "elseif" support to if. Also, "then", "else", and
1.519 +"elseif" may no longer be abbreviated.
1.520 +*** POTENTIAL INCOMPATIBILITY ***
1.521 +
1.522 +146. 12/28/92 Changed "puts" and "read" to support initial "-nonewline"
1.523 +switch instead of additional "nonewline" argument. The old form is
1.524 +still supported, but it is discouraged and is no longer documented.
1.525 +Also changed "puts" to make the file argument default to stdout: e.g.
1.526 +"puts foo" will print foo on standard output.
1.527 +
1.528 +147. 1/6/93 Fixed bug whereby backslash-newline wasn't working when
1.529 +typed interactively, or in "info complete".
1.530 +
1.531 +148. 1/22/93 Fixed bugs in "lreplace" and "linsert" where close
1.532 +quotes were being lost from last element before replacement or
1.533 +insertion.
1.534 +
1.535 +149. 1/29/93 Fixed bug in Tcl_AssembleCmd where it wasn't requiring
1.536 +a newline at the end of a line before considering a command to be
1.537 +complete. The bug caused some very long lines in script files to
1.538 +be processed as multiple separate commands.
1.539 +
1.540 +150. 1/29/93 Various changes in Makefile to add more configuration
1.541 +options, simplify installation, fix bugs (e.g. don't use -f switch
1.542 +for cp), etc.
1.543 +
1.544 +151. 1/29/93 Changed "name1" and "name2" identifiers to "part1" and
1.545 +"part2" to avoid name conflicts with stupid C++ implementations that
1.546 +use "name1" and "name2" in a reserved way.
1.547 +
1.548 +152. 2/1/93 Added "putenv" procedure to replace the standard system
1.549 +version so that it will work correctly with Tcl's environment handling.
1.550 +
1.551 +----------------- Released version 6.6, 2/5/93 ------------------
1.552 +
1.553 +153. 2/10/93 Fixed bugs in config script: missing "endif" in libc loop,
1.554 +and tried to use strncasecmp.c instead of strcasecmp.c.
1.555 +
1.556 +154. 2/10/93 Makefile improvements: added RANLIB variable for easier
1.557 +Sys-V configuration, added SHELL variable for SGI systems.
1.558 +
1.559 +----------------- Released version 6.7, 2/11/93 ------------------
1.560 +
1.561 +153. 2/6/93 Changes in backslash processing:
1.562 + - \Cx, \Mx, \CMx, \e sequences no longer special
1.563 + - \<newline> also eats up any space after the newline, replacing
1.564 + the whole sequence with a single space character
1.565 + - Hex sequences like \x24 are now supported, along with ANSI C's \a.
1.566 + - "format" no longer does backslash processing on its format string
1.567 + - there is no longer any special meaning to a 0 return value from
1.568 + Tcl_Backslash
1.569 + - unknown backslash sequences, like (e.g. \*), are replaced with
1.570 + the following character (e.g. *), instead of just treating the
1.571 + backslash as an ordinary character.
1.572 +*** POTENTIAL INCOMPATIBILITY ***
1.573 +
1.574 +154. 2/6/93 Updated all copyright notices. The meaning hasn't changed
1.575 +at all but the wording does a better job of protecting U.C. from
1.576 +liability (according to U.C. lawyers, anyway).
1.577 +
1.578 +155. 2/6/93 Changed "regsub" so that it overwrites the result variable
1.579 +in all cases, even if there is no match.
1.580 +*** POTENTIAL INCOMPATIBILITY ***
1.581 +
1.582 +156. 2/8/93 Added support for XPG3 %n$ conversion specifiers to "format"
1.583 +command.
1.584 +
1.585 +157. 2/17/93 Fixed bug in Tcl_Eval where errors due to infinite
1.586 +recursion could result in core dumps.
1.587 +
1.588 +158. 2/17/93 Improved the auto-load mechanism to deal gracefully (i.e.
1.589 +return an error) with a situation where a library file that supposedly
1.590 +defines a procedure doesn't actually define it.
1.591 +
1.592 +159. 2/17/93 Renamed Tcl_UnixError procedure to Tcl_PosixError, and
1.593 +changed errorCode variable usage to use POSIX as keyword instead of
1.594 +UNIX.
1.595 +*** POTENTIAL INCOMPATIBILITY ***
1.596 +
1.597 +160. 2/19/93 Changes to exec and process control:
1.598 + - Added support for >>, >&, >>&, |&, <@, >@, and >&@ forms of redirection.
1.599 + - When exec puts processes into background, it returns a list of
1.600 + their pids as result.
1.601 + - Added support for <file, >file, etc. (i.e. no space between
1.602 + ">" and file name.
1.603 + - Added -keepnewline option.
1.604 + - Deleted Tcl_Fork and Tcl_WaitPids procedures (just use fork and
1.605 + waitpid instead).
1.606 + - Added waitpid compatibility procedure for systems that don't have
1.607 + it.
1.608 + - Added Tcl_ReapDetachedProcs procedure.
1.609 + - Changed "exec" to return an error if there is stderr output, even
1.610 + if the command returns a 0 exit status (it's always been documented
1.611 + this way, but the implementation wasn't correct).
1.612 + - If a process returns a non-zero exit status but doesn't generate
1.613 + any diagnostic output, then Tcl generates an error message for it.
1.614 +*** POTENTIAL INCOMPATIBILITY ***
1.615 +
1.616 +161. 2/25/93 Fixed two memory-management problems having to do with
1.617 +managing the old result during variable trace callbacks.
1.618 +
1.619 +162. 3/1/93 Added dynamic string library: Tcl_DStringInit, Tcl_DStringAppend,
1.620 +Tcl_DStringFree, Tcl_DStringResult, etc.
1.621 +
1.622 +163. 3/1/93 Modified glob command to only return the names of files that
1.623 +exist, and to only return names ending in "/" if the file is a directory.
1.624 +*** POTENTIAL INCOMPATIBILITY ***
1.625 +
1.626 +164. 3/19/93 Modified not to use system calls like "read" directly,
1.627 +but instead to use special Tcl procedures that retry automatically
1.628 +if interrupted by signals.
1.629 +
1.630 +165. 4/3/93 Eliminated "noSep" argument to Tcl_AppendElement, plus
1.631 +TCL_NO_SPACE flag for Tcl_SetVar and Tcl_SetVar2.
1.632 +*** POTENTIAL INCOMPATIBILITY ***
1.633 +
1.634 +166. 4/3/93 Eliminated "flags" and "termPtr" arguments to Tcl_Eval.
1.635 +*** POTENTIAL INCOMPATIBILITY ***
1.636 +
1.637 +167. 4/3/93 Changes to expressions:
1.638 + - The "expr" command now accepts multiple arguments, which are
1.639 + concatenated together with space separators.
1.640 + - Integers aren't automatically promoted to floating-point if they
1.641 + overflow the word size: errors are generated instead.
1.642 + - Tcl can now handle "NaN" and other special values if the underlying
1.643 + library procedures handle them.
1.644 + - When printing floating-point numbers, Tcl ensures that there is a "."
1.645 + or "e" in the number, so it can't be treated as an integer accidentally.
1.646 + The procedure Tcl_PrintDouble is available to provide this function
1.647 + in other contexts. Also, the variable "tcl_precision" can be used
1.648 + to set the precision for printing (must be a decimal number giving
1.649 + digits of precision).
1.650 + - Expressions now support transcendental and other functions, e.g. sin,
1.651 + acos, hypot, ceil, and round. Can add new math functions with
1.652 + Tcl_CreateMathFunc().
1.653 + - Boolean expressions can now have any of the string values accepted
1.654 + by Tcl_GetBoolean, such as "yes" or "no".
1.655 +*** POTENTIAL INCOMPATIBILITY ***
1.656 +
1.657 +168. 4/5/93 Changed Tcl_UnsetVar and Tcl_UnsetVar2 to return TCL_OK
1.658 +or TCL_ERROR instead of 0 or -1.
1.659 +*** POTENTIAL INCOMPATIBILITY ***
1.660 +
1.661 +169. 4/5/93 Eliminated Tcl_CmdBuf structure and associated procedures;
1.662 +can use Tcl_DStrings instead.
1.663 +*** POTENTIAL INCOMPATIBILITY ***
1.664 +
1.665 +170. 4/8/93 Changed interface to Tcl_TildeSubst to use a dynamic
1.666 +string for buffer space. This makes the procedure re-entrant and
1.667 +thread-safe, whereas it wasn't before.
1.668 +*** POTENTIAL INCOMPATIBILITY ***
1.669 +
1.670 +171. 4/14/93 Eliminated tclHash.h, and moved everything from it to
1.671 +tcl.h
1.672 +*** POTENTIAL INCOMPATIBILITY ***
1.673 +
1.674 +172. 4/15/93 Eliminated Tcl_InitHistory, made "history" command always
1.675 +be part of interpreter.
1.676 +*** POTENTIAL INCOMPATIBILITY ***
1.677 +
1.678 +173. 4/16/93 Modified "file" command so that "readable" option always
1.679 +exists, even on machines that don't support symbolic links (always returns
1.680 +same error as if the file wasn't a symbolic link).
1.681 +
1.682 +174. 4/26/93 Fixed bugs in "regsub" where ^ patterns didn't get handled
1.683 +right (pretended not to match when it really did, and looped infinitely
1.684 +if -all was specified).
1.685 +
1.686 +175. 4/29/93 Various improvements in the handling of variables:
1.687 + - Can create variables and array elements during a read trace.
1.688 + - Can delete variables during traces (note: unset traces will be
1.689 + invoked when this happens).
1.690 + - Can upvar to array elements.
1.691 + - Can retarget an upvar to another variable by re-issuing the
1.692 + upvar command with a different "other" variable.
1.693 +
1.694 +176. 5/3/93 Added Tcl_GetCommandInfo, which returns info about a Tcl
1.695 +command such as whether it exists and its ClientData. Also added
1.696 +Tcl_SetCommandInfo, which allows any of this information to be modified
1.697 +and also allows a command's delete procedure to have a different
1.698 +ClientData value than its command procedure.
1.699 +
1.700 +177. 5/5/93 Added Tcl_RegExpMatch procedure.
1.701 +
1.702 +178. 5/6/93 Fixed bug in "scan" where it didn't properly handle
1.703 +%% conversion specifiers. Also changed "scan" to use Tcl_PrintDouble
1.704 +for printing real values.
1.705 +
1.706 +179. 5/7/93 Added "-exact", "-glob", and "-regexp" options to "lsearch"
1.707 +command to allow different kinds of pattern matching.
1.708 +
1.709 +180. 5/7/93 Added many new switches to "lsort" to control the sorting
1.710 +process: "-ascii", "-integer", "-real", "-command", "-increasing",
1.711 +and "-decreasing".
1.712 +
1.713 +181. 5/10/93 Changes to file I/O:
1.714 + - Modified "open" command to support a list of POSIX access flags
1.715 + like {WRONLY CREAT TRUNC} in addition to current fopen-style
1.716 + access modes. Also added "permissions" argument to set permissions
1.717 + of newly-created files.
1.718 + - Fixed Scott Bolte's bug (can close stdin etc. in application and
1.719 + then re-open them with Tcl commands).
1.720 + - Exported access to Tcl's file table with new procedures Tcl_EnterFile
1.721 + and Tcl_GetOpenFile.
1.722 +
1.723 +182. 5/15/93 Added new "pid" command, which can be used to retrieve
1.724 +either the current process id or a list of the process ids in a
1.725 +pipeline opened with "open |..."
1.726 +
1.727 +183. 6/3/93 Changed to use GNU autoconfig for configuration instead of
1.728 +the home-brew "config" script. Also made many other configuration-related
1.729 +changes, such as using <unistd.h> instead of explicitly declaring system
1.730 +calls in tclUnix.h.
1.731 +
1.732 +184. 6/4/93 Fixed bug where core-dumps could occur if a procedure
1.733 +redefined itself (the memory for the procedure's body could get
1.734 +reallocated in the middle of evaluating the body); implemented
1.735 +simple reference count mechanism.
1.736 +
1.737 +185. 6/5/93 Changed tclIndex file format in two ways: (a) it's now
1.738 +eval-ed instead of parsed, which makes it 3-4x faster; (b) the entries
1.739 +in auto_index are now commands to evaluate, which allows commands to
1.740 +be loaded in different ways such as dynamic-loading of C code. The
1.741 +old tclIndex file format is still supported.
1.742 +
1.743 +186. 6/7/93 Eliminated tclTest program, added new "tclsh" program
1.744 +that is more like wish (allows script files to be invoked automatically
1.745 +using "#!/usr/local/bin/tclsh", makes arguments available to script,
1.746 +etc.). Added support for Tcl_AppInit plus default version; this
1.747 +allows new Tcl applications to be created without modifying the
1.748 +main program for tclsh.
1.749 +
1.750 +187. 6/7/93 Fixed bug in TclWordEnd that kept backslash-newline from
1.751 +working correctly in some cases during interactive input.
1.752 +
1.753 +188. 6/9/93 Added Tcl_LinkVar and related procedures, which automatically
1.754 +keep a Tcl variable in sync with a C variable.
1.755 +
1.756 +189. 6/16/93 Increased maximum nesting depth from 100 to 1000.
1.757 +
1.758 +190. 6/16/93 Modified "trace var" command so that error messages from
1.759 +within traces are returned properly as the result of the variable
1.760 +access, instead of the generic "access disallowed by trace command"
1.761 +message.
1.762 +
1.763 +191. 6/16/93 Added Tcl_CallWhenDeleted to provide callbacks when an
1.764 +interpreter is deleted (same functionality as Tcl_WatchInterp, which
1.765 +used to exist in versions before 6.0).
1.766 +
1.767 +193. 6/16/93 Added "-code" argument to "return" command; it's there
1.768 +primarily for completeness, so that procedures implementing control
1.769 +constructs can reflect exceptional conditions back to their callers.
1.770 +
1.771 +194. 6/16/93 Split up Tcl.n to make separate manual entries for each
1.772 +Tcl command. Tcl.n now contains a summary of the language syntax.
1.773 +
1.774 +195. 6/17/93 Added new "switch" command to replace "case": allows
1.775 +alternate forms of pattern matching (exact, glob, regexp), replaces
1.776 +pattern lists with single patterns (but you can use "-" bodies to
1.777 +share one body among several patterns), eliminates "in" noise word.
1.778 +"Case" command is now obsolete.
1.779 +
1.780 +196. 6/17/93 Changed the "exec", "glob", "regexp", and "regsub" commands
1.781 +to include a "--" switch. All initial arguments starting with "-" are now
1.782 +treated as switches unless a "--" switch is present to end the list.
1.783 +*** POTENTIAL INCOMPATIBILITY ***
1.784 +
1.785 +197. 6/17/93 Changed auto-exec so that the subprocess gets stdin, stdout,
1.786 +and stderr from the parent. This allows truly interactive sub-processes
1.787 +(e.g. vi) to be auto-exec'ed from a tcl shell command line.
1.788 +
1.789 +198. 6/18/93 Added patchlevel.h, for use in coordinating future patch
1.790 +releases, and also added "info patchlevel" command to make the patch
1.791 +level available to Tcl scripts.
1.792 +
1.793 +199. 6/19/93 Modified "glob" command so that a leading "//" in a name
1.794 +gets left as is (this is needed for systems like Apollos where "//" is
1.795 +the super-root; Tcl used to collapse the two slashes into a single
1.796 +slash).
1.797 +
1.798 +200. 7/7/93 Added Tcl_SetRecursionLimit procedure so that the maximum
1.799 +allowable nesting depth can be controlled for an interpreter from C.
1.800 +
1.801 +----------------- Released version 7.0 Beta 1, 7/9/93 ------------------
1.802 +
1.803 +201. 7/12/93 Modified Tcl_GetInt and tclExpr.c so that full-precision
1.804 +unsigned integers can be specified without overflow errors.
1.805 +
1.806 +202. 7/12/93 Configuration changes: eliminate leading blank line in
1.807 +configure script; provide separate targets in Makefile for installing
1.808 +binary and non-binary information; check for size_t and a few other
1.809 +potentially missing typedefs; don't put tclAppInit.o into libtcl.a;
1.810 +better checks for matherr support.
1.811 +
1.812 +203. 7/14/93 Changed tclExpr.c to check the termination pointer before
1.813 +errno after strtod calls, to avoid problems with some versions of
1.814 +strtod that set errno in unexpected ways.
1.815 +
1.816 +204. 7/16/93 Changed "scan" command to be more ANSI-conformant:
1.817 +eliminated %F, %D, etc., added code to ignore "l", "h", and "L"
1.818 +modifiers but always convert %e, %f, and %g with implicit "l";
1.819 +also added support for %u and %i. Also changed "format" command
1.820 +to eliminate %D, %U, %O, and add %i.
1.821 +*** POTENTIAL INCOMPATIBILITY ***
1.822 +
1.823 +205. 7/17/93 Changed "uplevel" and "upvar" so that they can be used
1.824 +from global level to global level: this used to generate an error.
1.825 +
1.826 +206. 7/19/93 Renamed "setenv", "putenv", and "unsetenv" procedures
1.827 +to avoid conflicts with system procedures with the same names. If
1.828 +you want Tcl's procedures to override the system procedures, do it
1.829 +in the Makefile (instructions are in the Makefile).
1.830 +*** POTENTIAL INCOMPATIBILITY ***
1.831 +
1.832 +----------------- Released version 7.0 Beta 2, 7/21/93 ------------------
1.833 +
1.834 +207. 7/21/93 Fixed bug in tclVar.c where freed memory was accidentally
1.835 +used if a procedure returned an element of a local array.
1.836 +
1.837 +208. 7/22/93 Fixed bug in "unknown" where it didn't properly handle
1.838 +errors occurring in the "auto_load" procedure, leaving its state
1.839 +inconsistent.
1.840 +
1.841 +209. 7/23/93 Changed exec's ">2" redirection operator to "2>" for
1.842 +consistency with sh. This is incompatible with earlier beta releases
1.843 +of 7.0 but not with pre-7.0 releases, which didn't support either
1.844 +operator.
1.845 +
1.846 +210. 7/28/93 Changed backslash-newline handling so that the resulting
1.847 +space character *is* treated as a word separator unless the backslash
1.848 +sequence is in quotes or braces. This is incompatible with 7.0b1
1.849 +and 7.0b2 but is more compatible with pre-7.0 versions that the b1
1.850 +and b2 releases were.
1.851 +
1.852 +211. 7/28/93 Eliminated Tcl_LinkedVarWritable, added TCL_LINK_READ_ONLY to
1.853 +Tcl_LinkVar to accomplish same purpose. This change is incompatible
1.854 +with earlier beta releases, but not with releases before Tcl 7.0.
1.855 +
1.856 +212. 7/29/93 Renamed regexp C functions so they won't clash with POSIX
1.857 +regexp functions that use the same name.
1.858 +
1.859 +213. 8/3/93 Added "-errorinfo" and "-errorcode" options to "return"
1.860 +command: these allow for much better handling of the errorInfo
1.861 +and errorCode variables in some cases.
1.862 +
1.863 +214. 8/12/93 Changed "expr" so that % always returns a remainder with
1.864 +the same sign as the divisor and absolute value smaller than the
1.865 +divisor.
1.866 +
1.867 +215. 8/14/93 Turned off auto-exec in "unknown" unless the command
1.868 +was typed interactively. This means you must use "exec" when
1.869 +invoking subprocesses, unless it's a command that's typed interactively.
1.870 +*** POTENTIAL INCOMPATIBILITY ***
1.871 +
1.872 +216. 8/14/93 Added support for tcl_prompt1 and tcl_prompt2 variables
1.873 +to tclMain.c: makes prompts user-settable.
1.874 +
1.875 +217. 8/14/93 Added asynchronous handlers (Tcl_AsyncCreate etc.) so
1.876 +that signals can be taken cleanly by Tcl applications.
1.877 +
1.878 +218. 8/16/93 Moved information about open files from the interpreter
1.879 +structure to global variables so that a file can be opened in one
1.880 +interpreter and read or written in another.
1.881 +
1.882 +219. 8/16/93 Removed ENV_FLAGS from Makefile, so that there's no
1.883 +official support for overriding setenv, unsetenv, and putenv.
1.884 +
1.885 +220. 8/20/93 Various configuration improvements: coerce chars
1.886 +to unsigned chars before using macros like isspace; source ~/.tclshrc
1.887 +file during initialization if it exists and program is running
1.888 +interactively; allow there to be directories in auto_path that don't
1.889 +exist or don't have tclIndex files (ignore them); added Tcl_Init
1.890 +procedure and changed Tcl_AppInit to call it.
1.891 +
1.892 +221. 8/21/93 Fixed bug in expr where "+", "-", and " " were all
1.893 +getting treated as integers with value 0.
1.894 +
1.895 +222. 8/26/93 Added "tcl_interactive" variable to tclsh.
1.896 +
1.897 +223. 8/27/93 Added procedure Tcl_FilePermissions to return whether a
1.898 +given file can be read or written or both. Modified Tcl_EnterFile
1.899 +to take a permissions mask rather than separate read and write arguments.
1.900 +
1.901 +224. 8/28/93 Fixed performance bug in "glob" command (unnecessary call
1.902 +to "access" for each file caused a 5-10x slow-down for big directories).
1.903 +
1.904 +----------------- Released version 7.0 Beta 3, 8/28/93 ------------------
1.905 +
1.906 +225. 9/9/93 Renamed regexp.h to tclRegexp.h to avoid conflicts with system
1.907 +include file by same name.
1.908 +
1.909 +226. 9/9/93 Added Tcl_DontCallWhenDeleted.
1.910 +
1.911 +227. 9/16/93 Changed not to call exit C procedure directly; instead
1.912 +always invoke "exit" Tcl command so that application can redefine the
1.913 +command to do additional cleanup.
1.914 +
1.915 +228. 9/17/93 Changed auto-exec to handle names that contain slashes
1.916 +(i.e. don't use PATH for them).
1.917 +
1.918 +229. 9/23/93 Fixed bug in "read" and "gets" commands where they didn't
1.919 +clear EOF conditions.
1.920 +
1.921 +----------------- Released version 7.0, 9/29/93 ------------------
1.922 +
1.923 +230. 10/7/93 "Scan" command wasn't properly aligning things in memory,
1.924 +so segmentation faults could arise under some circumstances.
1.925 +
1.926 +231. 10/7/93 Fixed bug in Tcl_ConvertElement where it forgot to
1.927 +backslash leading curly brace when creating lists.
1.928 +
1.929 +232. 10/7/93 Eliminated dependency of tclMain.c on tclInt.h and
1.930 +tclUnix.h, so that people can copy the file out of the Tcl source
1.931 +directory to make modified private versions.
1.932 +
1.933 +233. 10/8/93 Fixed bug in auto-loader that reversed the priority order
1.934 +of entries in auto_path for new-style index files. Now things are
1.935 +back to the way they were before 3.0: first in auto_path is always
1.936 +highest priority.
1.937 +
1.938 +234. 10/13/93 Fixed bug where Tcl_CommandComplete didn't recognize
1.939 +comments and treat them as such. Thus if you typed the line
1.940 + # {
1.941 +interactively, Tcl would think that the command wasn't complete and
1.942 +wait for more input before evaluating the script.
1.943 +
1.944 +235. 10/14/93 Fixed bug where "regsub" didn't set the output variable
1.945 +if the input string was empty.
1.946 +
1.947 +236. 10/23/93 Fixed bug where Tcl_CreatePipeline didn't close off enough
1.948 +file descriptors in child processes, causing children not to exit
1.949 +properly in some cases.
1.950 +
1.951 +237. 10/28/93 Changed "list" and "concat" commands not to generate
1.952 +errors if given zero arguments, but instead to just return an empty
1.953 +string.
1.954 +
1.955 +----------------- Released version 7.1, 11/4/93 ------------------
1.956 +
1.957 +Note: there is no 7.2 release. It was flawed and was thus withdrawn
1.958 +shortly after it was released.
1.959 +
1.960 +238. 11/10/93 TclMain.c didn't compile on some systems because of
1.961 +R_OK in call to "access". Changed to eliminate call to "access".
1.962 +
1.963 +----------------- Released version 7.3, 11/26/93 ------------------
1.964 +
1.965 +239. 11/6/93 Modified "lindex", "linsert", "lrange", and "lreplace"
1.966 +so that "end" can be specified as an index.
1.967 +
1.968 +240. 11/6/93 Modified "append" and "lappend" to allow only two
1.969 +words total (i.e., nothing to append) without generating an error.
1.970 +
1.971 +241. 12/2/93 Changed to use EAGAIN as the errno for non-blocking
1.972 +I/O instead of EWOULDBLOCK: this should fix problem where non-blocking
1.973 +I/O didn't work correctly on System-V systems.
1.974 +
1.975 +242. 12/22/93 Fixed bug in expressions where cancelled evaluation
1.976 +wasn't always working correctly (e.g. "set one 1; eval {1 || 1/$one}"
1.977 +failed with a divide by zero error).
1.978 +
1.979 +243. 1/6/94 Changed TCL_VOLATILE definition from -1 to the address of
1.980 +a dummy procedure Tcl_Volatile, since -1 causes portability problems on
1.981 +some machines (e.g., Crays).
1.982 +
1.983 +244. 2/4/94 Added support for unary plus.
1.984 +
1.985 +245. 2/17/94 Changed Tcl_RecordAndEval and "history" command to
1.986 +call Tcl_GlobalEval instead of Tcl_Eval. Otherwise, invocation of
1.987 +these facilities in nested procedures can cause unwanted results.
1.988 +
1.989 +246. 2/17/94 Fixed bug in tclExpr.c where an expression such as
1.990 +"expr {"12398712938788234-1298379" != ""}" triggers an integer
1.991 +overflow error for the number in quotes, even though it isn't really
1.992 +a proper integer anyway.
1.993 +
1.994 +247. 2/19/94 Added new procedure Tcl_DStringGetResult to move result
1.995 +from interpreter to a dynamic string.
1.996 +
1.997 +248. 2/19/94 Fixed bug in Tcl_DStringResult that caused it to overwrite
1.998 +the contents of a static result in some situations. This can cause
1.999 +bizarre errors such as variables suddenly having empty values.
1.1000 +
1.1001 +249. 2/21/94 Fixed bug in Tcl_AppendElement, Tcl_DStringAppendElement,
1.1002 +and the "lappend" command that caused improper omission of a separator
1.1003 +space in some cases. For example, the script
1.1004 + set x "abc{"; lappend x "def"
1.1005 +used to return the result "abc{def" instead of "abc{ def".
1.1006 +
1.1007 +250. 3/3/94 Tcl_ConvertElement was outputting empty elements as \0 if
1.1008 +TCL_DONT_USE_BRACES was set. This depends on old pre-7.0 meaning of
1.1009 +\0, which is no longer in effect, so it didn't really work. Changed
1.1010 +to output empty elements as {} always.
1.1011 +
1.1012 +251. 3/3/94 Renamed Tcl_DStringTrunc to Tcl_DStringSetLength and extended
1.1013 +it so that it can be used to lengthen a string as well as shorten it.
1.1014 +Tcl_DStringTrunc is defined as a macro for backward compatibility, but
1.1015 +it is deprecated.
1.1016 +
1.1017 +252. 3/3/94 Added Tcl_AllowExceptions procedure.
1.1018 +
1.1019 +253. 3/13/94 Fixed bug in Tcl_FormatCmd that could cause "format"
1.1020 +to mis-behave on 64-bit Big-Endian machines.
1.1021 +
1.1022 +254. 3/13/94 Changed to use vfork instead of fork on systems where
1.1023 +vfork exists.
1.1024 +
1.1025 +255. 3/23/94 Fixed bug in expressions where ?: didn't associate
1.1026 +right-to-left as they should.
1.1027 +
1.1028 +256. 4/3/94 Fixed "exec" to flush any files used in >@ or >&@
1.1029 +redirection in exec, so that data buffered for them is written
1.1030 +before any new data added by the subprocess.
1.1031 +
1.1032 +257. 4/3/94 Added "subst" command.
1.1033 +
1.1034 +258. 5/20/94 The tclsh main program is now called Tcl_Main; tclAppInit.c
1.1035 +has a "main" procedure that calls Tcl_Main. This makes it easier to use
1.1036 +Tcl with C++ programs, which need their own main programs, and it also
1.1037 +allows an application to prefilter the argument list before calling
1.1038 +Tcl_Main.
1.1039 +*** POTENTIAL INCOMPATIBILITY ***
1.1040 +
1.1041 +259. 6/6/94 Fixed bug in procedure returns where the errorInfo variable
1.1042 +could get truncated if an unset trace was invoked as part of returning
1.1043 +from the procedure.
1.1044 +
1.1045 +260. 6/13/94 Added "wordstart" and "wordend" options to "string" command.
1.1046 +
1.1047 +261. 6/27/94 Fixed bug in expressions where they didn't properly cancel
1.1048 +the evaluation of math functions in &&, ||, and ?:.
1.1049 +
1.1050 +262. 7/11/94 Incorrect boolean values, like "ogle", weren't being
1.1051 +handled properly.
1.1052 +
1.1053 +263. 7/15/94 Added Tcl_RegExpCompile, Tcl_RegExpExec, and Tcl_RegExpRange,
1.1054 +which provide lower-level access to regular expression pattern matching.
1.1055 +
1.1056 +264. 7/22/94 Fixed bug in "glob" command where "glob -nocomplain ~bad_user"
1.1057 +would complain about a missing user. Now it doesn't complain anymore.
1.1058 +
1.1059 +265. 8/4/94 Fixed bug with linked variables where they didn't behave
1.1060 +correctly when accessed via upvars.
1.1061 +
1.1062 +266. 8/17/94 Fixed bug in Tcl_EvalFile where it didn't clear interp->result.
1.1063 +
1.1064 +267. 8/31/94 Modified "open" command so that errors in exec-ing
1.1065 +subprocesses are returned by the open immediately, rather than
1.1066 +being delayed until the "close" is executed.
1.1067 +
1.1068 +268. 9/9/94 Modified "expr" command to generate errors for integer
1.1069 +overflow (includes addition, subtraction, negation, multiplication,
1.1070 +division).
1.1071 +
1.1072 +269. 9/23/94 Modified "regsub" to return a count of the number of
1.1073 +matches and replacements, rather than 0/1.
1.1074 +
1.1075 +279. 10/4/94 Added new features to "array" command:
1.1076 + - added "get" and "set" commands for easy conversion between arrays
1.1077 + and lists.
1.1078 + - added "exists" command to see if a variable is an array, changed
1.1079 + "names" and "size" commands to treat a non-existent array (or scalar
1.1080 + variable) just like an empty one.
1.1081 + - added pattern option to "names" command.
1.1082 +
1.1083 +280. 10/6/94 Modified Tcl_SetVar2 so that read traces on variables get
1.1084 +called during append operations.
1.1085 +
1.1086 +281. 10/20/94 Fixed bug in "read" command where reading from stdin
1.1087 +required two control-D's to stop the reading.
1.1088 +
1.1089 +282. 11/3/94 Changed "expr" command to use longs for division just like
1.1090 +all other expr operators; it previously used ints for division.
1.1091 +
1.1092 +283. 11/4/94 Fixed bugs in "unknown" procedure: it wasn't properly
1.1093 +handling exception returns from commands that were executed after
1.1094 +being auto-loaded.
1.1095 +
1.1096 +----------------- Released version 7.4b1, 12/23/94 ------------------
1.1097 +
1.1098 +284. 12/26/94 Fixed "install" target in Makefile (couldn't always
1.1099 +find install program).
1.1100 +
1.1101 +285. 12/26/94 Added strcncasecmp procedure to compat directory.
1.1102 +
1.1103 +286. 1/3/95 Fixed all procedure calls to explicitly cast arguments:
1.1104 +implicit conversions from prototypes (especially integer->double)
1.1105 +don't work when compiling under non-ANSI compilers. Tcl is now clean
1.1106 +under gcc -Wconversion.
1.1107 +
1.1108 +287. 1/4/95 Fixed problem in Tcl_ArrayCmd where same name was used for
1.1109 +both a label and a variable; caused problems on several older compilers,
1.1110 +making array command misbehave and causing many errors in Tcl test suite.
1.1111 +
1.1112 +----------------- Released version 7.4b2, 1/12/95 ------------------
1.1113 +
1.1114 +288. 2/9/95 Modified Tcl_CreateCommand to return a token, and added
1.1115 +Tcl_GetCommandName procedure. Together, these procedures make it possible
1.1116 +to track renames of a command.
1.1117 +
1.1118 +289. 2/13/95 Fixed bug in expr where "089" was interpreted as a
1.1119 +floating-point number rather than a bogus octal number.
1.1120 +*** POTENTIAL INCOMPATIBILITY ***
1.1121 +
1.1122 +290. 2/14/95 Added code to Tcl_GetInt and Tcl_GetDouble to check for
1.1123 +overflows when reading in numbers.
1.1124 +
1.1125 +291. 2/18/95 Changed "array set" to stop after first error, rather than
1.1126 +continuing after error.
1.1127 +
1.1128 +292. 2/20/95 Upgraded to use autoconf version 2.2.
1.1129 +
1.1130 +293. 2/20/95 Fixed core dump that could occur in "scan" command if a
1.1131 +close bracket was omitted.
1.1132 +
1.1133 +294. 2/27/95 Changed Makefile to always use install-sh for installations:
1.1134 +there's just too much variation among "install" system programs, which
1.1135 +makes installation flakey.
1.1136 +
1.1137 +----------------- Released version 7.4b3, 3/24/95 ------------------
1.1138 +
1.1139 +3/25/95 (bug fix) Changed "install" to "./install" in Makefile so that
1.1140 +"make install" will work even when "." isn't in the search path.
1.1141 +
1.1142 +3/29/95 (bug fix) Fixed bug where the auto-loading mechanism wasn't
1.1143 +protecting the values of the errorCode and errorInfo variables.
1.1144 +
1.1145 +3/29/95 (new feature) Added optional pattern argument to "parray" procedure.
1.1146 +
1.1147 +3/29/95 (bug fix) Made the full functionality of
1.1148 + "return -code ... -errorcode ..."
1.1149 +work not just inside procedures, but also in sourced files and at
1.1150 +top level.
1.1151 +
1.1152 +4/6/95 (new feature) Added "pattern" option to "array names" command.
1.1153 +
1.1154 +4/18/95 (bug fix) Fixed bug in parser where it didn't allow backslash-newline
1.1155 +immediately after an argument in braces or quotes.
1.1156 +
1.1157 +4/19/95 (new feature) Added tcl_library variable, which application can
1.1158 +set to override default library directory.
1.1159 +
1.1160 +4/30/95 (bug fix) During trace callbacks for array elements, the variable
1.1161 +name used in the original reference would be temporarily modified to
1.1162 +separate the array name and element name; if the trace callback used
1.1163 +the same name string, it would get the wrong name (the array name without
1.1164 +element). Fixed to restore the variable name before making trace
1.1165 +callbacks.
1.1166 +
1.1167 +4/30/95 (new feature) Added -nobackslashes, -nocommands, and -novariables
1.1168 +switches to "subst" command.
1.1169 +
1.1170 +5/4/95 (new feature) Added TCL_EVAL_GLOBAL flag to Tcl_RecordAndEval.
1.1171 +
1.1172 +5/5/95 (bug fix) Format command would overrun memory when printing
1.1173 +integers with very large precision, as in "format %.1000d 0".
1.1174 +
1.1175 +5/5/95 (portability improvement) Changed to use BSDgettimeofday on
1.1176 +IRIX machines, to avoid compilation problems with the gettimeofday
1.1177 +declaration.
1.1178 +
1.1179 +5/6/95 (bug fix) Changed manual entries to use the standard .TH
1.1180 +macro instead of a custom .HS macro; the .HS macro confuses index
1.1181 +generators like makewhatis.
1.1182 +
1.1183 +5/9/95 (bug fix) Modified configure script to check for Solaris bug
1.1184 +that makes vfork unreliable (core dumps result if vforked child
1.1185 +changes a signal handler); will use fork instead of vfork if the
1.1186 +bug is present.
1.1187 +
1.1188 +6/5/95 (bug fix) Modified "lsort" command to disallow recursive calls
1.1189 +to lsort from a comparison function. This is needed because qsort
1.1190 +is not reentrant.
1.1191 +
1.1192 +6/5/95 (bug fix) Undid change 243 above: changed TCL_VOLATILE and
1.1193 +TCL_DYNAMIC back to integer constants rather than procedure addresses.
1.1194 +This was needed because procedure addresses can have multiple values
1.1195 +under some dynamic loading systems (e.g. SunOS 4.1 and Windows).
1.1196 +
1.1197 +6/8/95 (feature change) Modified interface to Tcl_Main to pass in the
1.1198 +address of the application-specific initialization procedure.
1.1199 +Tcl_AppInit is no longer hardwired into Tcl_Main. This is needed
1.1200 +in order to make Tcl a shared library.
1.1201 +
1.1202 +6/8/95 (feature change) Modified Makefile so that the installed versions
1.1203 +of tclsh and libtcl.a have version number in them (e.g. tclsh7.4 and
1.1204 +libtcl7.4.a) and the library directory name also has an embedded version
1.1205 +number (e.g., /usr/local/lib/tcl7.4). This should make it easier for
1.1206 +Tcl 7.4 to coexist with earlier versions.
1.1207 +
1.1208 +----------------- Released version 7.4b4, 6/16/95 ------------------
1.1209 +
1.1210 +6/19/95 (bug fix) Fixed bugs in tclCkalloc.c that caused core dumps
1.1211 +if TCL_MEM_DEBUG was enabled on word-addressed machines such as Crays.
1.1212 +
1.1213 +6/21/95 (feature removal) Removed overflow checks for integer arithmetic:
1.1214 +they just cause too much trouble (e.g. for random number generators).
1.1215 +
1.1216 +6/28/95 (new features) Added tcl_patchLevel and tcl_version variables,
1.1217 +for consistency with Tk.
1.1218 +
1.1219 +6/29/95 (bug fix) Fixed problem in Tcl_Eval where it didn't record
1.1220 +the right termination character if a script ended with a comment. This
1.1221 +caused erroneous output for the following command, among others:
1.1222 +puts "[
1.1223 +expr 1+1
1.1224 +# duh!
1.1225 +]"
1.1226 +
1.1227 +6/29/95 (message change) Changed the error message for ECHILD slightly
1.1228 +to provide a hint about why the problem is occurring.
1.1229 +
1.1230 +----------------- Released version 7.4, 7/1/95 ------------------
1.1231 +
1.1232 +7/18/95 (bug fix) Changed "lreplace" so that nothing is deleted if
1.1233 +the last index is less than the first index or if the last index
1.1234 +is < 0.
1.1235 +
1.1236 +7/18/95 (bug fix) Fixed bugs with backslashes in comments:
1.1237 +Tcl_CommandComplete (and "info complete") didn't properly handle
1.1238 +strings ending in backslash-newline, and neither Tcl_CommandComplete
1.1239 +nor the Tcl parser handled other backslash sequences right, such
1.1240 +as two backslashes before a newline.
1.1241 +
1.1242 +7/19/95 (bug fix) Modified Tcl_DeleteCommand to delete the hash table
1.1243 +entry for the command before invoking its callback. This is needed in
1.1244 +order to deal with reentrancy.
1.1245 +
1.1246 +7/22/95 (bug fix) "exec" wasn't reaping processes correctly after
1.1247 +certain errors (e.g. if the name of the executable was bogus, as
1.1248 +in "exec foobar").
1.1249 +
1.1250 +7/27/95 (bug fix) Makefile.in wasn't using the LIBS variable provided
1.1251 +by the "configure" script. This caused problems on some SCO systems.
1.1252 +
1.1253 +7/27/95 (bug fix) The version of strtod in fixstrtod.c didn't properly
1.1254 +handle the case where endPtr == NULL.
1.1255 +
1.1256 +----------------- Released patch 7.4p1, 7/29/95 -----------------------
1.1257 +
1.1258 +8/4/95 (bug fix) C-level trace callbacks for variables were sometimes
1.1259 +receiving the PART1_NOT_PARSED flag, which could cause errors in
1.1260 +subsequent Tcl library calls using the flags. (JO)
1.1261 +
1.1262 +8/4/95 (bug fix) Calls to toupper and tolower weren't using the
1.1263 +UCHAR macros, which caused trouble in non-U.S. locales. (JO)
1.1264 +
1.1265 +8/10/95 (new feature) Added the "load" command for dynamic loading of
1.1266 +binary packages, and the Tcl_PackageInitProc prototype for package
1.1267 +initialization procedures. (JO)
1.1268 +
1.1269 +8/23/95 (new features) Added "info sharedlibextension" and
1.1270 +"info nameofexecutable" commands, plus Tcl_FindExtension procedure. (JO)
1.1271 +
1.1272 +8/25/95 (bug fix) If the target of an "upvar" was non-existent but
1.1273 +had traces set, the traces were silently lost. Change to generate
1.1274 +an error instead. (JO)
1.1275 +
1.1276 +8/25/95 (bug fix) Undid change from 7/19, so that commands can stay
1.1277 +around while their deletion callbacks execute. Added lots of code to
1.1278 +handle all of the reentrancy problems that this opens up. (JO)
1.1279 +
1.1280 +8/25/95 (bug fix) Fixed core dump that could occur in TclDeleteVars
1.1281 +if there was an upvar from one entry in the table to the next entry
1.1282 +in the same table. (JO)
1.1283 +
1.1284 +8/28/95 (bug fix) Exec wasn't handling bad user names properly, as
1.1285 +in "exec ~bogus_user/foo". (JO)
1.1286 +
1.1287 +8/29/95 (bug fixes) Changed backslash-newline handling to correct two
1.1288 +problems:
1.1289 + - Only spaces and tabs following the backslash-newline are now
1.1290 + absorbed as part of the backslash-newline. Newlinew are no
1.1291 + longer absorbed (add another backslash if you want to absorb
1.1292 + another newline).
1.1293 + - TclWordEnd returns the character just before the backslash in
1.1294 + the sequence as the end of the sequence; it used to not consider
1.1295 + the backslash-newline as a word separator. (JO)
1.1296 +
1.1297 +8/31/95 (new feature) Changed man page installation (with "mkLinks"
1.1298 +script) to create additional links for manual pages corresponding to
1.1299 +each of the procedure and command names described in the pages. (JO)
1.1300 +
1.1301 +9/10/95 Reorganized Tcl sources for Windows and Mac ports. All sources
1.1302 +are now in subdirectories: "generic" contains sources that work on all
1.1303 +platforms, "windows", "mac", and "unix" directories contain platform-
1.1304 +specific sources. Some UNIX sources are also used on other platforms. (SS)
1.1305 +
1.1306 +9/10/95 (feature change) Eliminated exported global variables (they
1.1307 +don't work with Windows DLLs). Replaced tcl_AsyncReady and
1.1308 +tcl_FileCloseProc with procedures Tcl_AsyncReady() and
1.1309 +Tcl_SetFileCloseProc(). Replaced C variable tcl_RcFileName with
1.1310 +a Tcl variable tcl_rcFileName. (SS)
1.1311 +*** POTENTIAL INCOMPATIBILITY ***
1.1312 +
1.1313 +9/11/95 (new feature) Added procedure Tcl_SetPanicProc to override
1.1314 +the default implementation of "panic". (SS)
1.1315 +
1.1316 +9/11/95 (new feature) Added "interp" command to allow creation of
1.1317 +new interpreters and execution of untrusted scripts. Added many new
1.1318 +procedures, such as Tcl_CreateSlave, Tcl_CreateAlias,and Tcl_MakeSafe,
1.1319 +to provide C-level access to the interpreter facility. This mechanism
1.1320 +now provides almost all of the generic functions of Borenstein's and
1.1321 +Rose's Safe-Tcl (but not any Tk or email-related stuff). (JL)
1.1322 +
1.1323 +9/11/95 (feature change) Changed file management so that files are
1.1324 +no longer shared between interpreters: a file cannot normally be
1.1325 +referenced in one interpreter if it was opened in another. This
1.1326 +feature is needed to support safe interpreters. Added Tcl_ShareHandle()
1.1327 +procedure for allowing files to be shared, and added "interp" argument
1.1328 +to Tcl_FilePermissions procedure. (JL)
1.1329 +*** POTENTIAL INCOMPATIBILITY ***
1.1330 +
1.1331 +9/11/95 (new feature) Added "AssocData" mechanism, whereby extensions
1.1332 +can associate their own data with an interpreter and get called back
1.1333 +when the interpreter is deleted. This is visible at C level via the
1.1334 +procedures Tcl_SetAssocData and Tcl_GetAssocData. (JL)
1.1335 +
1.1336 +9/11/95 (new feature) Added Tcl_ErrnoMsg to translate an errno value
1.1337 +into a human-readable string. This is now used instead of calling
1.1338 +strerror because strerror mesages vary dramatically from platform
1.1339 +to platform, which messes up Tcl tests. Tcl_ErrnoMsg uses the standard
1.1340 +POSIX messages for all the common signals, and calls strerror for
1.1341 +signals it doesn't understand.
1.1342 +
1.1343 +----------------- Released patch 7.4p2, 9/15/95 -----------------------
1.1344 +
1.1345 +----------------- Released 7.5a1, 9/15/95 -----------------------
1.1346 +
1.1347 +9/22/95 (bug fix) Changed auto_mkindex to create tclIndex files that
1.1348 +handle directories whose paths might contain spaces. (RJ)
1.1349 +
1.1350 +9/27/95 (bug fix) The "format" command didn't check for huge or negative
1.1351 +width specifiers, which could cause core dumps. (JO)
1.1352 +
1.1353 +9/27/95 (bug fix) Core dumps could occur if an interactive command typed
1.1354 +to tclsh returned a very long result for tclsh to print out. The bug is
1.1355 +actually in printf (in Solaris 2.3 and 2.4, at least); switched to use
1.1356 +puts instead. (JO)
1.1357 +
1.1358 +9/28/95 (bug fix) Changed makefile.bc to eliminate a false dependency
1.1359 +for tcl1675.dll on the Borland run time library. (SS)
1.1360 +
1.1361 +9/28/95 (bug fix) Fixed tcl75.dll so it looks for tcl1675.dll instead
1.1362 +of tcl16.dll. (SS)
1.1363 +
1.1364 +9/28/95 (bug fix) Tcl was not correctly detecting the difference
1.1365 +between Win32s and Windows '95. (SS)
1.1366 +
1.1367 +9/28/95 (bug fix) "exec" was not passing environment changes to child
1.1368 +processes under Windows. (SS)
1.1369 +
1.1370 +9/28/95 (bug fix) Changed Tcl to ensure that open files are not passed
1.1371 +to child processes under Windows. (SS)
1.1372 +
1.1373 +9/28/95 (bug fix) Fixed Windows '95 and NT versions of exec so it can
1.1374 +handle both console and windows apps. (SS)
1.1375 +
1.1376 +9/28/95 (bug fix) Fixed Windows version of exec so it no longer leaves
1.1377 +temp files lying around. Also changed it so the temp files are
1.1378 +created in the appropriate system dependent temp directory. (SS)
1.1379 +
1.1380 +9/28/95 (bug fix) Eliminated source dependency on the Win32s Universal
1.1381 +Thunk header file, since it is not bundled with VC++. (SS)
1.1382 +
1.1383 +9/28/95 (bug fix) Under Windows, Tcl now constructs the HOME
1.1384 +environment variable from HOMEPATH and HOMEDRIVE when HOME is not
1.1385 +already set. (SS)
1.1386 +
1.1387 +9/28/95 (bug fix) Added support for "info nameofexecutable" and "info
1.1388 +sharedlibextension" to the Windows version. (SS)
1.1389 +
1.1390 +9/28/95 (bug fix) Changed tclsh to correctly parse command line
1.1391 +arguments so that backslashes are preserved under Windows. (SS)
1.1392 +
1.1393 +9/29/95 (bug fix) Tcl 7.5a1 treated either return or newline as end
1.1394 +of line in "gets", which caused lines ending in CRLF to be treated as
1.1395 +two separate lines. Changed to allow only character as end-of-line:
1.1396 +carriage return on Macs, newline elsewhere. (JO)
1.1397 +
1.1398 +9/29/95 (new feature) Changed to install "configInfo" file in same
1.1399 +directory as library scripts. It didn't used to get installed. (JO)
1.1400 +
1.1401 +9/29/95 (bug fix) Tcl was not converting Win32 errors into POSIX
1.1402 +errors under some circumstances. (SS)
1.1403 +
1.1404 +10/2/95 (bug fix) Safe interpreters no longer get initialized with
1.1405 +a call to Tcl_Init(). (JL)
1.1406 +
1.1407 +10/1/95 (new feature) Added "tcl_platform" global variable to provide
1.1408 +environment information such as the instruction set and operating
1.1409 +system. (JO)
1.1410 +
1.1411 +10/1/95 (bug fix) "exec" command wasn't always generating the
1.1412 +"child process exited abnormally" message when it should have. (JO)
1.1413 +
1.1414 +10/2/95 (bug fix) Changed "mkLinks.tcl" so that the scripts it generates
1.1415 +won't create links that overwrite original manual entries (there was
1.1416 +a problem where pack-old.n was overwriting pack.n). (JO)
1.1417 +
1.1418 +10/2/95 (feature change) Changed to use -ldl for dynamic loading under
1.1419 +Linux if it is available, but fall back to -ldld if it isn't. (JO)
1.1420 +
1.1421 +10/2/95 (bug fix) File sharing was causing refcounts to reach 0
1.1422 +prematurely for stdin, stdout and stderr, under some circumstances. (JL)
1.1423 +
1.1424 +10/2/95 (platform support) Added support for Visual C++ compiler on
1.1425 +Windows, Windows '95 and Windows NT, code donated by Gordon Chaffee. (JL)
1.1426 +
1.1427 +10/3/95 (bug fix) Tcl now frees any libraries that it loads before it
1.1428 +exits. (SS)
1.1429 +
1.1430 +10/03/95 (bug fix) Fixed bug in Macintosh ls command where the -l
1.1431 +and -C options would fail in anything but the HOME directory. (RJ)
1.1432 +
1.1433 +----------------- Released 7.5a2, 10/6/95 -----------------------
1.1434 +
1.1435 +10/10/95 (bug fix) "file dirnam /." was returning ":" on UNIX instead
1.1436 +of "/". (JO)
1.1437 +
1.1438 +10/13/95 (bug fix) Eliminated dependency on MKS toolkit for generating
1.1439 +the tcl.def file from Borland object files. (SS)
1.1440 +
1.1441 +10/17/95 (new features) Moved the event loop from Tcl to Tk, made major
1.1442 +revisions along the way:
1.1443 + - New Tcl commands: after, update, vwait (replaces "tkwait variable").
1.1444 + - "tkerror" is now replaced with "bgerror".
1.1445 + - The following procedures are similar to their old Tk counterparts:
1.1446 + Tcl_DoOneEvent, Tcl_Sleep, Tcl_DoWhenIdle, Tcl_CancelIdleCall,
1.1447 + Tcl_CreateFileHandler, Tcl_DeleteFileHandler, Tcl_CreateTimerHandler,
1.1448 + Tcl_DeleteTimerHandler, Tcl_BackgroundError.
1.1449 + - Revised notifier, add new concept of "event source" with the following
1.1450 + procedures: Tcl_CreateEventSource, Tcl_DeleteEventSource,
1.1451 + Tcl_WatchFile, Tcl_SetMaxBlockTime, Tcl_FileReady, Tcl_QueueEvent,
1.1452 + Tcl_WaitForEvent. (JO)
1.1453 +
1.1454 +10/31/95 (new features) Implemented cross platform file name support to make
1.1455 +it easier to write cross platform scripts. Tcl now understands 4 file naming
1.1456 +conventions: Windows (both DOS and UNC), Mac, Unix, and Network. The network
1.1457 +convention is a new naming mechanism that can be used to paths in a platform
1.1458 +independent fashion. See the "file" command manual page for more details.
1.1459 +The primary interfaces changes are:
1.1460 + - All Tcl commands that expect a file name now accept both network and
1.1461 + native form.
1.1462 + - Two new "file" subcommands, "nativename" and "networkname", provide a
1.1463 + way to convert between network and native form.
1.1464 + - Renamed Tcl_TildeSubst to Tcl_TranslateFileName, and changed it so that
1.1465 + it always returns a filename in native form. Tcl_TildeSubst is defined
1.1466 + as a macro for backward compatibility, but it is deprecated. (SS)
1.1467 +
1.1468 +11/5/95 (new feature) Made "tkerror" and "bgerror" synonyms, so that
1.1469 +either name can be used to manipulate the command (provides temporary
1.1470 +backward compatibility for existing scripts that use tkerror). (JO)
1.1471 +
1.1472 +11/5/95 (new feature) Added exit handlers and new C procedures
1.1473 +Tcl_CreateExitHandler, Tcl_DeleteExitHandler, and Tcl_Exit. (JO)
1.1474 +
1.1475 +11/6/95 (new feature) Added pid command for Macintosh version of
1.1476 +Tcl (it didn't previously exist on the Mac). (RJ)
1.1477 +
1.1478 +11/7/95 (new feature) New generic IO facility and support for IO to
1.1479 +files, pipes and sockets based on a common buffering scheme. Support
1.1480 +for asynchronous (non-blocking) IO and for event driver IO. Support
1.1481 +for automatic (background) asynchronous flushing and asynchronous
1.1482 +closing of channels. (JL)
1.1483 +
1.1484 +11/7/95 (new feature) Added new commands "fconfigure" and "fblocked"
1.1485 +to support new I/O features such as nonblocking I/O. Added "socket"
1.1486 +command for creating TCP client and server sockets. (JL).
1.1487 +
1.1488 +11/7/95 (new feature) Complete set of C APIs to the new generic IO
1.1489 +facility:
1.1490 + - Opening channels: Tcl_OpenFileChannel, Tcl_OpenCommandChannel,
1.1491 + Tcl_OpenTcpClient, Tcl_OpenTcpServer.
1.1492 + - I/O procedures on channels, which roughly mirror the ANSI C stdio
1.1493 + library: Tcl_Read, Tcl_Gets, Tcl_Write, Tcl_Flush, Tcl_Seek,
1.1494 + Tcl_Tell, Tcl_Close, Tcl_Eof, Tcl_InputBlocked, Tcl_GetChannelOption,
1.1495 + Tcl_SetChannelOption.
1.1496 + - Extension mechanism for creating new kinds of channels:
1.1497 + Tcl_CreateChannel, Tcl_GetChannelInstanceData, Tcl_GetChannelType,
1.1498 + Tcl_GetChannelName, Tcl_GetChannelFile, Tcl_RegisterChannel,
1.1499 + Tcl_UnregisterChannel, Tcl_GetChannel.
1.1500 + - Event-driven I/O on channels: Tcl_CreateChannelHandler,
1.1501 + Tcl_DeleteChannelHandler. (JL)
1.1502 +
1.1503 +11/7/95 (new feature) Channel driver interface specification to allow
1.1504 +new types of channels to be added easily to Tcl. Currently being used
1.1505 +in three drivers - for files, pipes and TCP-based sockets. (JL).
1.1506 +
1.1507 +11/7/95 (new feature) interp delete now takes any number of path
1.1508 +names of interpreters to delete, including zero. (JL).
1.1509 +
1.1510 +11/8/95 (new feature) implemented 'info hostname' and Tcl_GetHostName
1.1511 +command to get host name of machine on which the Tcl process is running. (JL)
1.1512 +
1.1513 +11/9/95 (new feature) Implemented file APIs for access to low level files
1.1514 +on each system. The APIs are: Tcl_CloseFile, Tcl_OpenFile, Tcl_ReadFile,
1.1515 +Tcl_WriteFile and Tcl_SeekFile. Also implemented Tcl_WaitPid which waits
1.1516 +in a system dependent manner for a child process. (JL)
1.1517 +
1.1518 +11/9/95 (new feature) Added Tcl_UpdateLinkedVar procedure to force a
1.1519 +Tcl variable to be updated after its C variable changes. (JO)
1.1520 +
1.1521 +11/9/95 (bug fix) The glob command has been totally reimplemented so
1.1522 +that it can support different file name conventions. It now handles
1.1523 +Windows file names (both UNC and drive-relative) properly. It also
1.1524 +supports nested braces correctly now. (SS)
1.1525 +
1.1526 +11/13/95 (bug fix) Fixed Makefile.in so that configure can be run
1.1527 +from a clean directory separate from the Tcl source tree, and compilations
1.1528 +can be performed there. (JO)
1.1529 +
1.1530 +11/14/95 (bug fix) Fixed file sharing between interpreters and file
1.1531 +transferring between interpreters to correctly manage the refcount so that
1.1532 +files are closed when the last reference to them is discarded. (JL)
1.1533 +
1.1534 +11/14/95 (bug fix) Fixed gettimeofday implementation for the
1.1535 +Macintosh. This fixes several timing related bugs. (RJ)
1.1536 +
1.1537 +11/17/95 (new feature) Added missing support for info nameofexecutable
1.1538 +on the Macintosh. (RJ)
1.1539 +
1.1540 +11/17/95 (bug fix) The Tcl variables argc argv and argv0 now return
1.1541 +something reasonable on the Mac. (RJ)
1.1542 +
1.1543 +11/22/95 (new feature) Implemented "auto-detect" mode for end of line
1.1544 +translations. On input, standalone "\r" mean MAC mode, standalone "\n"
1.1545 +mean Unix mode and "\r\n" means Windows mode. On output, the mode is
1.1546 +modified to whatever the platform specific mode for that platform is. (JL)
1.1547 +
1.1548 +11/24/95 (feature change) Replaced "configInfo" file with tclConfig.sh,
1.1549 +which is more complete and uses slightly different names. Also
1.1550 +arranged for tclConfig.sh to be installed in the platform-specific
1.1551 +library directory instead of Tcl's script library directory. (JO)
1.1552 +*** POTENTIAL INCOMPATIBILITY with Tcl 7.5a2, but not with Tcl 7.4 ***
1.1553 +
1.1554 +----------------- Released patch 7.4p3, 11/28/95 -----------------------
1.1555 +
1.1556 +12/5/95 (new feature) Added Tcl_File facility to support platform-
1.1557 +independent file handles. Changed all interfaces that used Unix-
1.1558 +style integer fd's to use Tcl_File's instead. (SS)
1.1559 +*** POTENTIAL INCOMPATIBILITY ***
1.1560 +
1.1561 +12/5/95 (new feature) Added a new "clock" command to Tcl. The command
1.1562 +allows you to get the current "clicks" or seconds & allows you to
1.1563 +format or scan human readable time/date strings. (RJ)
1.1564 +
1.1565 +12/18/95 (new feature) Moved Tk_Preserve, Tk_Release, and Tk_EventuallyFree
1.1566 +to Tcl, renamed to Tcl_Preserve, Tcl_Release, and Tcl_EventuallyFree. (JO)
1.1567 +
1.1568 +12/18/95 (new feature) Added new "package" command and associated
1.1569 +procedures Tcl_PkgRequire and Tcl_PkgProvide. Also wrote
1.1570 +pkg_mkIndex library procedure to create index files from binaries
1.1571 +and scripts. (JO)
1.1572 +
1.1573 +12/20/95 (new feature) Added Tcl_WaitForFile procedure. (JO)
1.1574 +
1.1575 +12/21/95 (new features) Made package name argument to "load" optional
1.1576 +(Tcl will now attempt to guess the package name if necessary). Also
1.1577 +added Tcl_StaticPackage and support in "load" for statically linked
1.1578 +packages. (JO)
1.1579 +
1.1580 +12/22/95 (new feature) Upgraded the foreach command to accept multiple
1.1581 +loop variables and multiple value lists. This lets you iterate over
1.1582 +multiple lists in parallel, and/or assign multiple loop variables from
1.1583 +one value list during each iteration. The only potential compatibility
1.1584 +problem is with scripts that used loop variables with a name that could be
1.1585 +construed to be a list of variable names (i.e. contained spaces). (BW)
1.1586 +
1.1587 +1/5/96 (new feature) Changed tclsh so it builds as a console mode
1.1588 +application under Windows. Now tclsh can be used from the command
1.1589 +line with pipes or interactively. Note that this only works under
1.1590 +Windows 95 or NT. (SS)
1.1591 +
1.1592 +1/17/96 (new feature) Modified Makefile and configure script to allow
1.1593 +Tcl to be compiled as a shared library: use the --enable-shared option
1.1594 +when configuing. (JO)
1.1595 +
1.1596 +1/17/96 (removed obsolete features) Removed the procedures Tcl_EnterFile
1.1597 +and Tcl_GetOpenFile: these no longer make sense with the new I/O system. (JL)
1.1598 +*** POTENTIAL INCOMPATIBILITY ***
1.1599 +
1.1600 +1/19/96 (bug fixes) Prevented formation of circular aliases, through the
1.1601 +Tcl 'interp alias' command and through the 'rename' command, as well as
1.1602 +through the C API Tcl_CreateAlias. (JL)
1.1603 +
1.1604 +1/19/96 (bug fixes) Fixed several bugs in direct deletion of interpreters
1.1605 +with Tcl_DeleteInterp when the interpreter is a slave; fixes based on a
1.1606 +patch received from Viktor Dukhovni of ESM. (JL)
1.1607 +
1.1608 +1/19/96 (new feature) Implemented on-close handlers for channels; added
1.1609 +the C APIs Tcl_CreateCloseHandler and Tcl_DeleteCloseHandler. (JL)
1.1610 +
1.1611 +1/19/96 (new feature) Implemented portable error reporting mechanism; added
1.1612 +the C APIs Tcl_SetErrno and Tcl_GetErrno. (JL)
1.1613 +
1.1614 +1/24/96 (bug fix) Unknown command processing properly invokes external
1.1615 +commands under Windows NT and Windows '95 now. (SS)
1.1616 +
1.1617 +1/23/96 (bug fix) Eliminated extremely long startup times under Windows '95.
1.1618 +The problem was a result of the option database initialization code that
1.1619 +concatenated $HOME with /.Xdefaults, resulting in a // in the middle of the
1.1620 +file name. Under Windows '95, this is incorrectly interpreted as a UNC
1.1621 +path. They delays came from the network timeouts needed to determine that
1.1622 +the file name was invalid. Tcl_TranslateFileName now suppresses duplicate
1.1623 +slashes that aren't at the beginning of the file name. (SS)
1.1624 +
1.1625 +1/25/96 (bug fix) Changed exec and open to create children so they are
1.1626 +attached to the application's console if it exists. (SS)
1.1627 +
1.1628 +1/31/96 (bug fix) Fixed command line parsing to handle embedded
1.1629 +spaces under Windows. (SS)
1.1630 +
1.1631 +----------------- Released 7.5b1, 2/1/96 -----------------------
1.1632 +
1.1633 +2/7/96 (bug fix) Fixed off by one error in argument parsing code under
1.1634 +Windows. (SS)
1.1635 +
1.1636 +2/7/96 (bug fix) Fixed bugs in VC++ makefile that improperly
1.1637 +initialized the tcl75.dll. Fixed bugs in Borland makefile that caused
1.1638 +build failures under Windows NT. (SS)
1.1639 +
1.1640 +2/9/96 (bug fix) Fixed deadlock problem in AUTO end of line translation
1.1641 +mode which would cause a socket server with several concurrent clients
1.1642 +writing in CRLF mode to hang. (JL)
1.1643 +
1.1644 +2/9/96 (API change) Replaced -linemode option to fconfigure with a
1.1645 +new -buffering option, added "none" setting to enable immediate write. (JL)
1.1646 +*** INCOMPATIBILITY with b1 ***
1.1647 +
1.1648 +2/9/96 (new feature) Added C API Tcl_InputBuffered which returns the count
1.1649 +of bytes currently buffered in the input buffer of a channel, and o for
1.1650 +output only channels. (JL)
1.1651 +
1.1652 +2/9/96 (new feature) Implemented asynchronous connect for sockets. (JL)
1.1653 +
1.1654 +2/9/96 (new feature) Added C API Tcl_SetDefaultTranslation to set (per
1.1655 +channel) the default end of line translation mode. This is the mode that
1.1656 +will be installed if an output operation is done on the channel while it is
1.1657 +still in AUTO mode. (JL)
1.1658 +
1.1659 +2/9/96 (bug fix) Changed Tcl_OpenCommandChannel interface to properly
1.1660 +handle all of the combinations of stdio inheritance in background
1.1661 +pipelines. See the Tcl_OpenFileChannel(3) man page for more
1.1662 +info. This change fixes the bug where exec of a background pipeline
1.1663 +was not getting passed the stdio handles properly. (SS)
1.1664 +
1.1665 +2/9/96 (bug fix) Removed the new Tcl_CreatePipeline interface, and
1.1666 +restored the old version for Unix platforms only. All new code should
1.1667 +use Tcl_CreateCommandChannel instead. (SS)
1.1668 +
1.1669 +2/9/96 (bug fix) Changed Makefile.in to use -L and -ltcl7.5 for Tcl
1.1670 +library so that shared libraries are more likely to be found correctly
1.1671 +on more platforms. (JO)
1.1672 +
1.1673 +2/13/96 (new feature) Added C API Tcl_SetNotifierData and
1.1674 +Tcl_GetNotifierData to allow notifier and channel driver writers to
1.1675 +associate data with a Tcl_File. The result of this change is that
1.1676 +Tcl_GetFileInfo now always returns an OS file handle, and Tcl_GetFile
1.1677 +can be used to construct a Tcl_File for an externally constructed OS
1.1678 +handle. (SS)
1.1679 +
1.1680 +2/13/96 (bug fix) Changed Windows socket implementation so it doesn't
1.1681 +set SO_REUSEADDR on server sockets. Now attempts to create a server
1.1682 +socket on a port that is already in use will be properly identified
1.1683 +and an error will be generated. (SS)
1.1684 +
1.1685 +2/13/96 (bug fix) Fixed problems with DLL initialization under Visual
1.1686 +C++ that left the C run time library uninitialized. (SS)
1.1687 +
1.1688 +2/13/96 (bug fix) Fixed Windows socket initialization so it loads
1.1689 +winsock the first time it is used, rather than at the time tcl75.dll
1.1690 +is loaded. This should fix the bug where the modem immediately starts
1.1691 +trying to connect to a service provider when wish or tclsh are
1.1692 +started. (SS)
1.1693 +
1.1694 +2/13/96 (new feature) Added C APIs Tcl_MakeFileChannel and
1.1695 +Tcl_MakeTcpClientChannel to wrap up existing fds and sockets into
1.1696 +channels. Provided implementations on Unix and Windows. (JL)
1.1697 +
1.1698 +2/13/96 (bug fix) Fixed bug with seek leaving EOF and BLOCKING set. (JL)
1.1699 +
1.1700 +2/14/96 (bug fix) Fixed reentrancy problem in fileevent handling
1.1701 +and made it more robust in the face of errors. (JL)
1.1702 +
1.1703 +2/14/96 (feature change) Made generic IO level emulate blocking mode if the
1.1704 +channel driver is unable to provide it, e.g. if the low level device is
1.1705 +always nonblocking. Thus, now blocking behavior is an advisory setting for
1.1706 +channel drivers and can be ignored safely if the channel driver is unable
1.1707 +to provide it. (JL)
1.1708 +
1.1709 +2/15/96 (new feature) Added "binary" end of line translation mode, which is
1.1710 +a synonym of "lf" mode. (JL)
1.1711 +
1.1712 +2/15/96 (bug fix) Fixed reentrancy problem in fileevent handling vs
1.1713 +deletion of channel event handlers. (JL)
1.1714 +
1.1715 +2/15/96 (bug fix) Fixed bug in event handling which would cause a
1.1716 +nonblocking channel to not see further readable events after the first
1.1717 +readable event that had insufficient input. (JL)
1.1718 +
1.1719 +2/17/96 (bug fix) "info complete" didn't properly handle comments
1.1720 +in nested commands. (JO)
1.1721 +
1.1722 +2/21/96 (bug fix) "exec" under Windows NT/95 did not properly handle
1.1723 +very long command lines (>200 chars). (SS)
1.1724 +
1.1725 +2/21/96 (bug fix) Sockets could get into an infinite loop if a read
1.1726 +event arrived after all of the available data had been read. (SS)
1.1727 +
1.1728 +2/22/96 (bug fix) Added cast of st_size elements to (long) before
1.1729 +sprintf-ing in "file size" command. This is needed to handle systems
1.1730 +like NetBSD with 64-bit file offsets. (JO)
1.1731 +
1.1732 +----------------- Released 7.5b2, 2/23/96 -----------------------
1.1733 +
1.1734 +2/23/96 (bug fix) TCL_VARARGS macro in tcl.h wasn't defined properly
1.1735 +when compiling with C++. (JO)
1.1736 +
1.1737 +2/24/96 (bug fix) Removed dependencies on Makefile in the UNIX Makefile:
1.1738 +this caused problems on some platforms (like Linux?). (JO)
1.1739 +
1.1740 +2/24/96 (bug fix) Fixed configuration bug that made Tcl not compile
1.1741 +correctly on Linux machines with neither -ldl or -ldld. (JO)
1.1742 +
1.1743 +2/24/96 (new feature) Added a block of comments and definitions to
1.1744 +Makefile.in to make it easier to have Tcl's TclSetEnv etc. replace
1.1745 +the library procedures setenv etc, so that calls to setenv etc. in
1.1746 +the application automatically update the Tcl "env" variable. (JO)
1.1747 +
1.1748 +2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
1.1749 +to C API Tcl_Close and simplified closing of command channels. (JL)
1.1750 +*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
1.1751 +
1.1752 +2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
1.1753 +to C type definition Tcl_DriverCloseProc; modified all channel drivers to
1.1754 +implement close procedures that accept the additional argument. (JL)
1.1755 +*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
1.1756 +
1.1757 +2/28/96 (bug fix) Fixed memory leak that could occur if an upvar
1.1758 +referred to an element of an array in the same stack frame as the
1.1759 +upvar. (JO)
1.1760 +
1.1761 +2/29/96 (feature change) Modified both Tcl_DoOneEvent and Tcl_WaitForEvent
1.1762 +so that they return immediately in cases where they would otherwise
1.1763 +block forever (e.g. if there are no event handlers of any sort). (JO)
1.1764 +
1.1765 +2/29/96 (new feature) Added C APIs Tcl_GetChannelBufferSize and
1.1766 +Tcl_SetChannelBufferSize to set and retrieve the size, in bytes, for
1.1767 +buffers allocated to store input or output in a channel. (JL)
1.1768 +
1.1769 +2/29/96 (new feature) Added option -buffersize to Tcl fconfigure command
1.1770 +to allow Tcl scripts to query and set the size of channel buffers. (JL)
1.1771 +
1.1772 +2/29/96 (feature removed) Removed channel driver function to specify
1.1773 +the buffer size to use when allocating a buffer. Removed the C typedef
1.1774 +for Tcl_DriverBufferSizeProc. Channels are now created with a default
1.1775 +buffer size of 4K. (JL)
1.1776 +*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
1.1777 +
1.1778 +2/29/96 (feature change) The channel driver function for setting blocking
1.1779 +mode on the device may now be NULL. If the generic code detects that the
1.1780 +function is NULL, operations that set the blocking mode on the channel
1.1781 +simply succeed. (JL)
1.1782 +
1.1783 +3/2/96 (bug fix) Fixed core dump that could occur if a syntax error
1.1784 +(such as missing close paren) occurred in an array reference with a
1.1785 +very long array name. (JO)
1.1786 +
1.1787 +3/4/96 (bug fix) Removed code in the "auto_load" procedure that deletes
1.1788 +all existing auto-load information whenever the "auto_path" variable
1.1789 +is changed. Instead, new information adds to what was already there.
1.1790 +Otherwise, changing the "auto_path" variable causes all package-
1.1791 +related information to be lost. If you really want to get rid of
1.1792 +existing auto-load information, use auto_reset before setting auto_path. (JO)
1.1793 +
1.1794 +3/5/96 (new feature) Added version suffix to shared library names so that
1.1795 +Tcl will compile under NetBSD and FreeBSD (I hope). (JO)
1.1796 +
1.1797 +3/6/96 (bug fix) Cleaned up error messages in new I/O system to correspond
1.1798 +more closely to old I/O system. (JO)
1.1799 +
1.1800 +3/6/96 (new feature) Added -myaddr and -myport options to the socket
1.1801 +command, removed -tcp and -- options. This lets clients and servers
1.1802 +choose a particular interface. Also changed the default server address
1.1803 +from the hostname to INADDR_ANY. The server accept callback now gets
1.1804 +passed the client's port as well as IP address. The C interfaces for
1.1805 +Tcl_OpenTcpClient and Tcl_OpenTcpServer have changed to support the
1.1806 +above changes. (BW)
1.1807 +*** POTENTIAL INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
1.1808 +
1.1809 +3/6/96 (changed feature) The library function auto_mkindex will now
1.1810 +default to using the pattern "*.tcl" if no pattern is given. (RJ)
1.1811 +
1.1812 +3/6/96 (bug fix) The socket channel code for the Macintosh has been
1.1813 +rewritten to use native MacTcp. (RJ)
1.1814 +
1.1815 +3/7/96 (new feature) Added Tcl_SetStdChannel and Tcl_GetStdChannel
1.1816 +interfaces to allow applications to explicitly set and get the global
1.1817 +standard channels. (SS)
1.1818 +
1.1819 +3/7/96 (bug fix) Tcl did close not the file descriptors associated
1.1820 +with "stdout", etc. when the corresponding channels were closed. (SS)
1.1821 +
1.1822 +3/7/96 (bug fix) Reworked shared library and dynamic loading stuff to
1.1823 +try to get it working under AIX. Added new @SHLIB_LD_LIBS@ autoconf
1.1824 +symbol as part of this. AIX probably doesn't work yet, but it should
1.1825 +be a lot closer. (JO)
1.1826 +
1.1827 +3/7/96 (feature change) Added Tcl_ChannelProc typedef and changed the
1.1828 +signature of Tcl_CreateChannelHandler and Tcl_DeleteChannelHandler to take
1.1829 +Tcl_ChannelProc arguments instead of Tcl_FileProc arguments. This change
1.1830 +should not affect any code outside Tcl because the signatures of
1.1831 +Tcl_ChannelProc and Tcl_FileProc are compatible. (JL)
1.1832 +
1.1833 +3/7/96 (API change) Modified signature of Tcl_GetChannelOption to return
1.1834 +an int instead of char *, and to take a Tcl_DString * argument. Modified
1.1835 +the implementation so that the option name can be NULL, to mean that the
1.1836 +call should retrieve a list of alternating option names and values. (JL)
1.1837 +*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
1.1838 +
1.1839 +3/7/96 (API change) Added Tcl_DriverSetOptionProc, Tcl_DriverGetOptionProc
1.1840 +typedefs, added two slots setOptionProc and getOptionProc to the channel
1.1841 +type structure. These may be NULL to indicate that the channel type does
1.1842 +not support any options. (JL)
1.1843 +*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
1.1844 +
1.1845 +3/7/96 (feature change) stdin, stdout and stderr can now be put into
1.1846 +nonblocking mode. (JL)
1.1847 +
1.1848 +3/8/96 (feature change) Eliminated dependence on the registry for
1.1849 +finding the Tcl library files. (SS)
1.1850 +
1.1851 +----------------- Released 7.5b3, 3/8/96 -----------------------
1.1852 +
1.1853 +3/12/96 (feature improvement) Modified startup script to look in several
1.1854 +different places for the Tcl library directory. This should allow Tcl
1.1855 +to find the libraries under all but the weirdest conditions, even without
1.1856 +the TCL_LIBRARY environment variable being set. (JO)
1.1857 +
1.1858 +3/13/96 (bug fix) Eliminated use of the "linger" option from the Windows
1.1859 +socket implementation. (JL)
1.1860 +
1.1861 +3/13/96 (new feature) Added -peername and -sockname options for fconfigure
1.1862 +for socket channels. Code contributed by John Haxby of HP. (JL)
1.1863 +
1.1864 +3/13/96 (bug fix) Fixed panic and core dump that would occur if the accept
1.1865 +callback script on a server socket encountered an error. (JL)
1.1866 +
1.1867 +3/13/96 (feature change) Added -async option to the Tcl socket command.
1.1868 +If the command is creating a client socket and the flag is present, the
1.1869 +client is connected asynchronously. If the option is absent (the default),
1.1870 +the client socket is connected synchronously, and the command returns only
1.1871 +when the connection has been completed or failed. This change was suggested
1.1872 +by Mark Diekhans. (JL)
1.1873 +
1.1874 +3/13/96 (feature change) Modified the signature of Tcl_OpenTcpClient to
1.1875 +take an additional int argument, async. If nonzero, the client is connected
1.1876 +to the server asynchronously. If the value is zero, the connection is made
1.1877 +synchronously, and the call to Tcl_OpenTcpClient returns only when the
1.1878 +connection fails or succeeds. This change was suggested by Mark Diekhans. (JL)
1.1879 +*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
1.1880 +
1.1881 +3/14/96 (bug fix) "tclsh bogus_file_name" didn't print an error message. (JO)
1.1882 +
1.1883 +3/14/96 (bug fix) Added new procedures to tclCkalloc.c so that libraries
1.1884 +and applications can be compiled with TCL_MEM_DEBUG even if Tcl isn't
1.1885 +(however, the converse is still not true). Patches provided by Jan
1.1886 +Nijtmans. (JO)
1.1887 +
1.1888 +3/15/96 (bug fix) Marked standard IO handles of a process as close-on-exec
1.1889 +to fix bug in Ultrix where exec was not sharing standard IO handles with
1.1890 +subprocesses. Fix suggested by Mark Diekhans. (JL)
1.1891 +
1.1892 +3/15/96 (bug fix) Fixed asynchronous close mechanism so that it closes the
1.1893 +channel instead of leaking system resources. The manifestation was that Tcl
1.1894 +would eventually run out of file descriptors if it was handling a large
1.1895 +number of nonblocking sockets or pipes with high congestion. (JL)
1.1896 +
1.1897 +3/15/96 (bug fix) Fixed tests so that they no longer leak file descriptors.
1.1898 +The manifestation was that Tcl would eventually run out of file descriptors
1.1899 +if the tests were rerun many times (> a hundred times on Solaris). (JL)
1.1900 +
1.1901 +3/15/96 (bug fix) Fixed channel creation code so that it never creates
1.1902 +unnamed channels. This would cause a panic and core dump when the channel
1.1903 +was closed. (JL)
1.1904 +
1.1905 +3/16/96 (bug fixes) Made lots of changes in configuration stuff to get
1.1906 +Tcl working under AIX (finally). Tcl should now support the "load"
1.1907 +command under AIX and should work either with or without shared
1.1908 +libraries for Tcl and Tk. (JO)
1.1909 +
1.1910 +3/21/96 (configuration improvement) Changed configure script so it
1.1911 +doesn't use version numbers (as in -ltcl7.5 and libtcl7.5.so) under
1.1912 +SunOS 4.1, where they don't work anyway. (JO)
1.1913 +
1.1914 +3/22/96 (new feature) Added C API Tcl_InterpDeleted that allows extension
1.1915 +writers to discover when an interpreter is being deleted. (JL)
1.1916 +
1.1917 +3/22/96 (bug fix) The standard IO channels are now added to each
1.1918 +trusted interpreter as soon as the interpreter is created. This ensures
1.1919 +against the bug where a child would do IO before the master had done any,
1.1920 +and then the child is destroyed - the standard IO channels would be then
1.1921 +closed and the master would be unable to do any IO. (JL)
1.1922 +
1.1923 +3/22/96 (bug fix) Made Tcl more robust against interpreter deletion, by
1.1924 +using Tcl_Preserve, Tcl_Release and Tcl_EventuallyFree to split the process
1.1925 +of interpreter deletion into two distinct phases. Also went through all of
1.1926 +Tcl and added calls to Tcl_Preserve and Tcl_Delete where needed. (JL)
1.1927 +
1.1928 +3/22/96 (bug fix) Fixed several places where C code was reading and writing
1.1929 +into freed memory, especially during interpreter deletion. (JL)
1.1930 +
1.1931 +3/22/96 (bug fix) Fixed very deep bug in Tcl_Release that caused memory to
1.1932 +be freed twice if the release callback did Tcl_Preserve and Tcl_Release on
1.1933 +the same memory as the chunk currently being freed. (JL)
1.1934 +
1.1935 +3/22/96 (bug fix) Removed several memory leaks that would cause memory
1.1936 +buildup on half-K chunks in the generic IO level. (JL)
1.1937 +
1.1938 +3/22/96 (bug fix) Fixed several core dumps which occurred when new
1.1939 +AssocData was being created during the cleanups in interpreter deletion.
1.1940 +The solution implemented now is to loop repeatedly over the AssocData until
1.1941 +none is left to clean up. (JL)
1.1942 +
1.1943 +3/22/96 (bug fix) Fixed a bug in event handling which caused an infinite
1.1944 +loop if there were no files being watched and no timer. Fix suggested by
1.1945 +Jan Nijtmans. (JL)
1.1946 +
1.1947 +3/22/96 (bug fix) Fixed Tcl_CreateCommand, Tcl_DeleteCommand to be more
1.1948 +robust if the interpreter is being deleted. Also fixed several order
1.1949 +dependency bugs in Tcl_DeleteCommand which kicked in when an interpreter
1.1950 +was being deleted. (JL)
1.1951 +
1.1952 +3/26/96 (bug fix) Upon a "short read", the generic code no longer calls
1.1953 +the driver for more input. Doing this caused blocking on some platforms
1.1954 +even on nonblocking channels. Bug and fix courtesy Mark Roseman. (JL)
1.1955 +
1.1956 +3/26/96 (new feature) Added 'package Tcltest' which is present only in
1.1957 +test versions of Tcl; this allows the testing commands to be loaded into
1.1958 +new interpreters besides the main one. (JL)
1.1959 +
1.1960 +3/26/96 (restored feature) Recreated the Tcl_GetOpenFile C API. You can
1.1961 +now get a FILE * from a registered channel; Unix only. (JL)
1.1962 +
1.1963 +3/27/96 (bug fix) The regular expression code did not support more
1.1964 +than 9 subexpressions. It now supports up to 20. (SS)
1.1965 +
1.1966 +4/1/96 (bug fixes) The CHANNEL_BLOCKED bit was being left on on a short
1.1967 +read, so that fileevents wouldn't fire correctly. Bug reported by Mark
1.1968 +Roseman.(JL, RJ)
1.1969 +
1.1970 +4/1/96 (bug fix) Moved Tcl_Release to match Tcl_Preserve exactly, in
1.1971 +tclInterp.c; previously interpreters were being freed only conditionally
1.1972 +and sometimes not at all. (JL)
1.1973 +
1.1974 +4/1/96 (bug fix) Fixed error reporting in slave interpreters when the
1.1975 +error message was being generated directly by C code. Fix suggested by
1.1976 +Viktor Dukhovni of ESM. (JL)
1.1977 +
1.1978 +4/2/96 (bug fixes) Fixed a series of bugs in Windows sockets that caused
1.1979 +events to variously get lost, to get sent multiple times, or to be ignored
1.1980 +by the driver. The manifestation was blocking if the channel is blocking,
1.1981 +and either getting EAGAIN or infinite loops if the channel is nonblocking.
1.1982 +This series of bugs was found by Ian Wallis of Cisco. Now all tests (also
1.1983 +those that were previously commented out) in socket.test pass. (JL, SS)
1.1984 +
1.1985 +4/2/96 (feature change/bug fix) Eliminated network name support in
1.1986 +favor of better native name support. Added "file split", "file join",
1.1987 +and "file pathtype" commands. See the "file" man page for more
1.1988 +details. (SS)
1.1989 +*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
1.1990 +
1.1991 +4/2/96 (bug fix) Changed implementation of auto_mkindex so tclIndex
1.1992 +files will properly handle path names in a cross platform context. (SS)
1.1993 +
1.1994 +4/5/96 (bug fix) Fixed Tcl_ReadCmd to use the channel buffer size as the
1.1995 +chunk size it reads, instead of a fixed 4K size. Thus, on large reads, the
1.1996 +user can set the channel buffer size to a large size and the read will
1.1997 +occur orders of magnitude faster. For example, on a 2MB file, reading in 4K
1.1998 +chunks took 34 seconds, while reading in 1MB chunks took 1.5 seconds (on a
1.1999 +SS-20). Problem identified and fix suggested by John Haxby of HP. (JL)
1.2000 +
1.2001 +4/5/96 (bug fix) Fixed socket creation code to invoke gethostbyname only if
1.2002 +inet_addr failed (very unlikely). Before this change the order was reversed
1.2003 +and this made things much slower than they needed to be (gethostbyname
1.2004 +generally requires an RPC, which is slow). Problem identified and fix
1.2005 +suggested by John Loverso of OSF. (JL)
1.2006 +
1.2007 +4/9/96 (feature change) Modified "auto" translation mode so that it
1.2008 +recognizes any of "\n", "\r" and "\r\n" in input as end of line, so
1.2009 +that a file can have mixed end-of-line sequences. It now outputs
1.2010 +the platform specific end of line sequence on each platform for files and
1.2011 +pipes, and for sockets it produces crlf in output on all platforms. (JL)
1.2012 +*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
1.2013 +
1.2014 +4/11/96 (new feature) Added -eofchar option to Tcl_SetChannelOption to allow
1.2015 +setting of an end of file character for input and output. If an input eof
1.2016 +char is set, it is recognized as EOF and further input from the channel is
1.2017 +not presented to the caller. If an output eof char is set, on output, that
1.2018 +byte is appended to the channel when it is closed. On Unix and Macintosh,
1.2019 +all channels start with no eof char set for input or output. On Windows,
1.2020 +files and pipes start with input and output eof chars set to Crlt-Z (ascii
1.2021 +26), and sockets start with no input or output eof char. (JL)
1.2022 +*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
1.2023 +
1.2024 +4/17/96 (bug fix) Fixed series of bugs with handling of crlf sequence split
1.2025 +across buffer boundaries in input, in AUTO mode. (JL, BW)
1.2026 +
1.2027 +4/17/96 (test suite improvement) Fixed test suite so that tests that
1.2028 +depend on the availability of Unix commands such as echo, cat and others
1.2029 +are not run if these commands are not present. (JL)
1.2030 +
1.2031 +4/17/96 (test suite improvement) The socket test now automatically starts,
1.2032 +on platformst that support exec, a separate process for remote testsing. (JL)
1.2033 +
1.2034 +----------------- Released 7.5, 4/21/96 -----------------------
1.2035 +
1.2036 +5/1/96 (bug fix) "file tail ~" did not correctly return the tail
1.2037 +portion of the user's home directory. (SS)
1.2038 +
1.2039 +5/1/96 (bug fix) Fixed bug in TclGetEnv where it didn't lookup environment
1.2040 +variables correctly: could confuse "H" and "HOME", for example. (JO)
1.2041 +
1.2042 +5/1/96 (bug fix) Changed to install tclConfig.sh under "make install-binaries",
1.2043 +not "make install-libraries". (JO)
1.2044 +
1.2045 +5/2/96 (bug fix) Changed pkg_mkIndex not to attempt to "load" a file unless
1.2046 +it has the standard shared library extension. On SunOS, attempts to load
1.2047 +Tcl scripts cause the whole application to be aborted (there's no way to
1.2048 +get the error back into Tcl). (JO)
1.2049 +
1.2050 +5/7/96 (bug fix) Moved initScript in tclUnixInit.c to writable memory to
1.2051 +avoid potential core dumps. (JO)
1.2052 +
1.2053 +5/7/96 (bug fix) Auto_reset procedure was removing procedure from init.tcl,
1.2054 +such as pkg_mkIndex. (JO)
1.2055 +
1.2056 +5/7/96 (bug fix) Fixed cast on socket address resolution code that
1.2057 +would cause a failure to connect on Dec Alphas. (JL)
1.2058 +
1.2059 +5/7/96 (bug fix) Added "time", "subst" and "fileevent" commands to set of
1.2060 +commands available in a safe interpreter. (JL)
1.2061 +
1.2062 +5/13/96 (bug fix) Preventing OS level handles for stdin, stdout and stderr
1.2063 +from being implicitly closed when the last reference to the standard
1.2064 +channel containing that handle is discarded when an interpreter is deleted.
1.2065 +Explicitly closing standard channels by using "close" still works. (JL)
1.2066 +
1.2067 +5/21/96 (bug fix) Do not create channels for stdin, stdout and stderr on
1.2068 +Unix if the devices are closed. This prevents a duplicate channel name
1.2069 +panic later on when the fd is used to open a channel and the channel is
1.2070 +registered in an interpreter. (JL)
1.2071 +
1.2072 +5/23/96 (bug fix) Fixed bug that prevented the use of standard channels in
1.2073 +interpreters created after the last interpreter was destroyed. In the sequence
1.2074 +
1.2075 + interp = Tcl_CreateInterp();
1.2076 + Tcl_DeleteInterp(interp);
1.2077 + interp = Tcl_CreateInterp();
1.2078 +
1.2079 +channels for stdio would not be available in the second interpreter. (JL)
1.2080 +
1.2081 +5/23/96 (bug fix) Fixed bug that allowed Tcl_MakeFileChannel to create new
1.2082 +channels with Tcl_Files in them that are already used by another channel.
1.2083 +This would cause core dumps when the Tcl_Files were being freed twice. (JL)
1.2084 +
1.2085 +5/23/96 (bug fix) Fixed a logical timing bug that caused a standard channel
1.2086 +to be removed from the standard channel table too early when the channel
1.2087 +was being closed. If the channel was being flushed asynchronously, it could
1.2088 +get recreated before being actually destroyed, and the recreated channel
1.2089 +would contain the same Tcl_File as the one being closed, leading to
1.2090 +dangling pointers and core dumps. (JL)
1.2091 +
1.2092 +5/27/96 (bug fix) Fixed a bug in Tcl_GetChannelOption which caused it to
1.2093 +always return a list of one element, a list of the settings, for
1.2094 +-translation and -eofchar options. Now correctly returns the value
1.2095 +described by the documentation (Mark Diekhans found this, thanks!). (JL)
1.2096 +
1.2097 +5/30/96 (bug fix) Fixed a couple of syntax errors in io.test. (JL)
1.2098 +
1.2099 +5/30/96 (bug fix) If a fileevent scripts gets an error, delete it before
1.2100 +causing a background error. This is to allow the error handler to reinstall
1.2101 +the fileevent and to prevent infinite loops if the event loop is reentered
1.2102 +in the error handler. (JL)
1.2103 +
1.2104 +5/31/96 (bug fix) Channels now will get properly flushed on exit. (JL)
1.2105 +
1.2106 +6/5/96 (bug fix) Changed Tcl_Ckalloc, Tcl_Ckfree, and Tcl_Ckrealloc to
1.2107 +Tcl_Alloc, Tcl_Free, and Tcl_Realloc. Added documentation for these
1.2108 +routines now that they are officially supported. Extension writers
1.2109 +should use these routines instead of free() and malloc(). (SS)
1.2110 +
1.2111 +6/10/96 (bug fix) Changes the Tcl close command so that it no longer
1.2112 +waits on nonblocking pipes for the piped processes to exit; instead it
1.2113 +reaps them in the background. (JL)
1.2114 +
1.2115 +6/11/96 (bug fix) Increased the length of the listen queue for server
1.2116 +sockets on Unix from 5 to 100. Some OSes will disregard this and reset it
1.2117 +to 5, but we should try to get as long a queue as we can, for performance
1.2118 +reasons. (JL)
1.2119 +
1.2120 +6/11/96 (bug fix) Fixed windows sockets bug that caused a cascade of events
1.2121 +if the fileevent script read less than was available. Now reading less than
1.2122 +is available does not cause a flood of Tcl events. (JL, SS)
1.2123 +
1.2124 +6/11/96 (bug fix) Fixed bug in background flushing on closed channels that
1.2125 +would prevent the last buffer from getting flushed. (JL)
1.2126 +
1.2127 +6/13/96 (bug fix) Fixed bug in Windows sockets that caused a core dump if
1.2128 +a DLL linked with tcl.dll and referred to e.g. ntohs() without opening a
1.2129 +Tcl socket. The problem was that the indirection table was not being
1.2130 +initialized. (JL)
1.2131 +
1.2132 +6/13/96 (bug fix) Fixed OS level resource leak that would occur when a
1.2133 +Tcl channel was still registered in some interpreter when the process
1.2134 +exits. Previously the channel was not being closed and the OS level handles
1.2135 +were not being released; the output was being flushed but the device was
1.2136 +not being closed. Now the device is properly closed. This was only a
1.2137 +problem on Win3.1 and MacOS. (JL, SS)
1.2138 +
1.2139 +6/28/96 (bug fix) Fixed bug where transient errors were leaving an error
1.2140 +code around, so that it would erroneously get reported later. This bug was
1.2141 +exercised intermittently by closing a channel to a file on a very loaded
1.2142 +NFS server, or to a socket whose other end blocked. (JL, BW)
1.2143 +
1.2144 +7/3/96 (bug fix) Fileevents declared in an interpreter are now deleted
1.2145 +when the channel is closed in that interpreter. Before this fix, the
1.2146 +fileevent would hang around until the channel is completely closed, and
1.2147 +would cause errors if events happened before the channel was closed. This
1.2148 +could happen in two cases: first if the channel is shared between several
1.2149 +interpreters, and second if an async flush is in progress that prevents the
1.2150 +channel from being closed until the flush finishes. (JL)
1.2151 +
1.2152 +7/10/96 (bug fix) Fixed bugs in both "lrange" and "lreplace" commands
1.2153 +where too much white space was being removed. For example, the command
1.2154 + lreplace {\}\ hello} end end
1.2155 +was returning "\}\", losing the significant space in the first list
1.2156 +element and corrupting the list. (JO)
1.2157 +
1.2158 +7/20/96 (bug fix) The procedure pkg_mkIndex didn't work properly for
1.2159 +extensions that depend on Tk, because it didn't load Tk into the child
1.2160 +interpreter before loading the extension. Now it loads Tk if Tk is
1.2161 +present in the parent. (JO)
1.2162 +
1.2163 +7/23/96 (bug fix) Added compat version of strftime to fix crashes
1.2164 +resulting from bad implementations under Windows. (SS)
1.2165 +
1.2166 +7/23/96 (bug fix) Standard implementations of gmtime() and localtime()
1.2167 +under Windows did not handle dates before 1970, so they were replaced
1.2168 +with a revised implementation. (SS)
1.2169 +
1.2170 +7/23/96 (bug fix) Tcl would crash on exit under Borland 5.0 because
1.2171 +the global environ pointer was left pointing to freed memory. (SS)
1.2172 +
1.2173 +7/29/96 (bug fix) Fixed memory leak in Tcl_LoadCmd that could occur if
1.2174 +a package's AppInit procedure called Tcl_StaticPackage to register
1.2175 +static packages. (JO)
1.2176 +
1.2177 +8/1/96 (bug fix) Fixed a series of bugs in Windows sockets so that async
1.2178 +writebehind in the presence of read event handlers now works, and so that
1.2179 +async writebehind also works on sockets for which a read event handler was
1.2180 +declared and whose channels were then closed before the async write
1.2181 +finished. The bug was reported by John Loverso and Steven Wahl,
1.2182 +independently, test case supplied by John Loverso. (JL)
1.2183 +
1.2184 +----------------- Released patch 7.5p1, 8/2/96 -----------------------
1.2185 +
1.2186 +5/8/96 (new feature) Added Tcl_GetChannelMode C API for retrieving whether
1.2187 +a channel is open for reading and writing. (JL)
1.2188 +
1.2189 +5/8/96 (API changes) Revised C APIs for channel drivers:
1.2190 + - Removed all Tcl_Files from channel driver interface; you can now have
1.2191 + channels that are not based on Tcl_Files.
1.2192 + - Added channelReadyProc and watchChannelProc procedures to interface;
1.2193 + these are used to implement event notification for channels.
1.2194 + - Added getFileProc to channel driver, to allow the generic IO code
1.2195 + to retrieve a Tcl_File from a channel (presumably if the channel
1.2196 + uses Tcl_Files they will be stored inside its instanceData). (JL)
1.2197 +*** INCOMPATIBILITY with Tcl 7.5 ***
1.2198 +
1.2199 +5/8/96 (API change) The Tcl_CreateChannel C API was modified to not take
1.2200 +Tcl_File arguments, and instead to take a mask specifying whether the
1.2201 +channel is readable and/or writable. (JL)
1.2202 +*** INCOMPATIBILITY with Tcl 7.5 ***
1.2203 +
1.2204 +6/3/96 (bug fix) Made Tcl_SetVar2 robust against the case where the value
1.2205 +of the variable is a NULL pointer instead of "". (JL)
1.2206 +
1.2207 +6/17/96 (bug fix) Fixed "reading uninitialized memory" error reported by
1.2208 +Purify, in Tcl_Preserve/Tcl_Release. (JL)
1.2209 +
1.2210 +8/9/96 (bug fix) Fixed bug in init.tcl that caused incorrect error message
1.2211 +if the act of autoloading a procedure caused the procedure to be invoked
1.2212 +again. (JO)
1.2213 +
1.2214 +8/9/96 (bug fix) Configure script produced bad library names and extensions
1.2215 +under SunOS and a few other platforms if the --disable-load switch was used.
1.2216 +(JO)
1.2217 +
1.2218 +8/9/96 (bug fix) Tcl_UpdateLinkedVar generated an error if the variable
1.2219 +being updated was read-only. (JO)
1.2220 +
1.2221 +8/14/96 (bug fix) The macintosh now supports synchronous socket
1.2222 +connections. Other minor bugs were also fixed. (RJ)
1.2223 +
1.2224 +8/15/96 (configuration improvement) Changed the file patchlevel.h
1.2225 +to be tclPatch.h. This avoids conflict with the Tk file and is now
1.2226 +in 8.3 format on the Windows platform. (RJ)
1.2227 +
1.2228 +8/20/96 (bug fix) Fixed core dump in interp alias command for interpreters
1.2229 +created with Tcl_CreateInterp (as opposed to with Tcl_CreateSlave). (JL)
1.2230 +
1.2231 +8/20/96 (bug fix) No longer masking ECONNRESET on Windows sockets so
1.2232 +that the higher level of the IO mechanism sees the error instead of
1.2233 +entering an infinite loop. (JL)
1.2234 +
1.2235 +8/20/96 (bug fix) Destroying the last interpreter no longer closes the
1.2236 +standard channels. (JL)
1.2237 +
1.2238 +8/20/96 (bug fix) Closing one of the stdin, stdout or stderr channels and
1.2239 +then opening a new channel now correctly assigns the new channel as the
1.2240 +standard channel that was closed. (JL)
1.2241 +
1.2242 +8/20/96 (bug fix) Added code to unix/tclUnixChan.c for using ioctl with
1.2243 +FIONBIO instead of fcntl with O_NONBLOCK, for those versions of Unix where
1.2244 +either O_NONBLOCK is not supported or implemented incorrectly. (JL)
1.2245 +
1.2246 +8/21/96 (bug fix) Fixed "file extension" so it correctly returns the
1.2247 +extension on files like "foo..c" as "..c" instead of ".c". (SS)
1.2248 +
1.2249 +8/22/96 (bug fix) If environ[] contains static strings, Tcl would core
1.2250 +dump in TclSetupEnv because it was trying to write NULLs into the actual
1.2251 +data in environ[]. Now we instead copy as appropriate. (JL)
1.2252 +
1.2253 +8/22/96 (added impl) Added missing implementation of Tcl_MakeTcpClientChannel
1.2254 +for Windows platform. Code contributed by Mark Diekhans. (JL)
1.2255 +
1.2256 +8/22/96 (new feature) Added a new memory allocator for the Macintosh
1.2257 +version of Tcl. It's quite a bit faster than MetroWerk's version. (RJ)
1.2258 +
1.2259 +8/26/96 (documentation update) Removed old change bars (for all changes
1.2260 +in Tcl 7.5 and earlier releases) from manual entries. (JO)
1.2261 +
1.2262 +8/27/96 (enhancement) The exec and open commands behave better and work in
1.2263 +more situations under Windows NT and Windows 95. Documentation describes
1.2264 +what is still lacking. (CS)
1.2265 +
1.2266 +8/27/96 (enhancement) The Windows makefiles will now compile even if the
1.2267 +compiler is not in the path and/or the compiler's environment variables
1.2268 +have not been set up. (CS)
1.2269 +
1.2270 +8/27/96 (configuration improvement) The Windows resource files are
1.2271 +automatically updated when the version/patch level changes. The header file
1.2272 +now has a comment that reminds the user which other files must be manually
1.2273 +updated when the version/patch level changes. (CS)
1.2274 +
1.2275 +8/28/96 (new feature) Added file manipulation features (copy, rename, delete,
1.2276 +mkdir) that are supported on all platforms. They are implemented as
1.2277 +subcommands to the "file" command. See the documentation for the "file"
1.2278 +command for more information. (JH)
1.2279 +
1.2280 +----------------- Released 7.6b1, 8/30/96 -----------------------
1.2281 +
1.2282 +9/3/96 (bug fix) Simplified code so that standard channels are created
1.2283 +lazily, they are added to an interpreter lazily, and they are never added
1.2284 +to a safe interpreter. (JL)
1.2285 +
1.2286 +9/3/96 (bug fix) Closing a channel after closing a standard channel, e.g.
1.2287 +stdout, would cause the implicit recreation of that standard channel. (JL)
1.2288 +
1.2289 +9/3/96 (new feature) Now calling Tcl_RegisterChannel with a NULL
1.2290 +interpreter increments the refcount so that code outside any interpreter
1.2291 +can use channels that are also registered in interpreters, without worrying
1.2292 +that the channel may turn into a dangling pointer at any time. Calling
1.2293 +Tcl_UnregisterChannel with a NULL interpreter only decrements the recount
1.2294 +so that code outside any interpreter can safely declare it is no longer
1.2295 +interested in a channel. (JL)
1.2296 +
1.2297 +9/4/96 (new features) Two changes to dynamic loading:
1.2298 + - If the file name is empty in the "load" command and there is no
1.2299 + statically loaded version of the package, a dynamically loaded
1.2300 + version will be used if there is one.
1.2301 + - Tcl_StaticPackage ignores redundant calls for the same package. (JO)
1.2302 +
1.2303 +9/6/96 (bug fix) Platform specific procedures for manipulating files are
1.2304 +no longer macros and have been prefixed with "Tclp", such as TclpRenameFile.
1.2305 +Unix file code now handles symbolic links and other special files correctly.
1.2306 +The semantics of file copy and file rename has been changed so that if
1.2307 +a target directory exists, the source files will NOT be merged with the
1.2308 +existing files. (JH)
1.2309 +
1.2310 +9/6/96 (bug fix) If standard channel is NULL, because Tcl cannot connect
1.2311 +to the standard channel, do not increment the refcount. The channel can
1.2312 +be NULL if there is for example no standard input. (JL)
1.2313 +
1.2314 +9/6/96 (portability improvement) Changed parsing of backslash sequences
1.2315 +like \n to translate directly to absolute values like 0xa instead of
1.2316 +letting the compiler do the translation. This guarantees that the
1.2317 +translation is done the same everywhere. (JO)
1.2318 +
1.2319 +9/9/96 (bug fix) If channel is opened and not associated with any
1.2320 +interpreter, but Tcl decides to use it as one of the standard channels, it
1.2321 +became impossible to close the channel with Tcl_Close -- instead you had
1.2322 +to call Tcl_UnregisterChannel. Fixed now so that it's safe to call
1.2323 +Tcl_Close even when Tcl is using the channel as one of the standard ones. (JL)
1.2324 +
1.2325 +9/11/96 (feature change) The Tcl library is now placed in the Tcl
1.2326 +shared libraries resource. You no longer need to place the Tcl files
1.2327 +in your applications explicitly. (RJ)
1.2328 +
1.2329 +9/11/96 (feature change) Extensions no longer automatically have the
1.2330 +resource fork of the extension opened for it. Instead you need to
1.2331 +use the tclMacLibrary.c file in your extension. (RJ)
1.2332 +*** POTENTIAL INCOMPATIBILITY ***
1.2333 +
1.2334 +9/12/96 (bug fix) The extension loading mechanism on the Macintosh now
1.2335 +looks at the 'cfrg' resource to determine where to load the code
1.2336 +fragment from. This means FAT fragments should now work. (RJ)
1.2337 +
1.2338 +9/18/96 (enhancement) The exec and open commands behave better and work in
1.2339 +more situations under Windows 3.X. Documentation describes what is still
1.2340 +lacking. (CS)
1.2341 +
1.2342 +9/19/96 (bug fix) Fixed a panic which would occur if you delete a
1.2343 +non-existent alias before any aliases are created. Now instead correctly
1.2344 +returns an error that the alias is not found. (JL)
1.2345 +
1.2346 +9/19/96 (bug fix) Slave interpreters could rename aliases and they would
1.2347 +not get deleted when the alias was being redefined. This led to dangling
1.2348 +pointers etc. (JL)
1.2349 +
1.2350 +9/19/96 (bug fix) Fixed a panic where a hash table entry was being deleted
1.2351 +twice during alias management operations. (JL)
1.2352 +
1.2353 +9/19/96 (bug fix) Fixed bug in event loop that could cause the input focus
1.2354 +in Tk to get confused during menu traversal, among other problems. The
1.2355 +problem was related to handling of the "marker" when its event was
1.2356 +deleted. (JO)
1.2357 +
1.2358 +9/26/96 (bug fix) Windows was losing EOF on a socket if the FD_CLOSE event
1.2359 +happened to precede any left over FD_READ events. Now correctly remembers
1.2360 +seeing FD_CLOSE, so that trailing FD_READ events are not discarded if they
1.2361 +do not contain any data. This allows Tcl to correctly get a zero read and
1.2362 +notice EOF. (JL)
1.2363 +
1.2364 +9/26/96 (bug fix) Was not resetting READABLE state properly on sockets
1.2365 +under Windows if the driver discarded an FD_READ event because no data was
1.2366 +present. Now correctly resets the state. (JL)
1.2367 +
1.2368 +9/30/96 (bug fix) Made EOF sticky on Windows sockets, so that fileevent
1.2369 +readable will fire repeatedly until the socket is closed. Previously the
1.2370 +fileevent fired only once. This could lead to never-closed connections if
1.2371 +the Tcl script in the fileevent wasn't closing the socket immediately. (JL)
1.2372 +
1.2373 +10/2/96 (new feature) Improved the package loader:
1.2374 + - Added new variable tcl_pkgPath, which holds the default
1.2375 + directories under which packages are normally installed (each
1.2376 + package goes in a separate subdirectory of a directory in
1.2377 + $tcl_pkgPath). These directories are included in auto_path by
1.2378 + default.
1.2379 + - Changed the package auto-loader to look for pkgIndex.tcl files
1.2380 + not only in the auto_path directories but also in their immediate
1.2381 + children. This should make it easier to install and uninstall
1.2382 + packages (don't have to change auto_path or merge pkgIndex.tcl
1.2383 + files). (JO)
1.2384 +
1.2385 +10/3/96 (bug fix) Changed tclsh to look for tclshrc.tcl instead of
1.2386 +tclsh.rc on startup under Windows. This is more consistent with wish and
1.2387 +uses the right extension. (SS)
1.2388 +*** POTENTIAL INCOMPATIBILITY ***
1.2389 +
1.2390 +10/8/96 (bug fix) Convertclock does not parse 24-hour times of the
1.2391 +form "hhmm" correctly when hour = 00. In the parse code, hour must be
1.2392 +>= 100 for minutes to be non-zero. Thanks to Lint LaCour for this
1.2393 +bug fix. (RJ)
1.2394 +
1.2395 +10/11/96 (bug fix) Under Windows, the pid command returned the process
1.2396 +handle instead of the process id. (SS)
1.2397 +
1.2398 +----------------- Released 7.6, 10/16/96 -----------------------
1.2399 +
1.2400 +10/29/96 (bug fix) Under Windows, sockets would consume 100% CPU time after
1.2401 +the first accept(), due to a typo. (JL)
1.2402 +
1.2403 +10/29/96 (bug fix) Incorrect refcount management caused standard channels
1.2404 +not to get deleted at process exit or DLL unload time, causing a memory
1.2405 +leak of upwards of 20K each time. (JL)
1.2406 +
1.2407 +11/7/96 (bug fix) Auto-exec didn't work on file names that contained
1.2408 +spaces. (JO)
1.2409 +
1.2410 +11/8/96 (bug fix) Fixed core dump that would occur if more than one call
1.2411 +to Tcl_DeleteChannelHandler was made to delete a given channel handler. (JL)
1.2412 +
1.2413 +11/8/96 (bug fix) Fixed test for return value in Tcl_Seek and Tcl_SeekCmd
1.2414 +to only treat -1 as error, instead of all negative numbers. (JL)
1.2415 +
1.2416 +11/12/96 (bug fix) Do not blocking waiting for processes at the end of a
1.2417 +pipe during exit cleanup. (JL)
1.2418 +
1.2419 +11/12/96 (bug fix) If we are in exit cleanup, do not close the system level
1.2420 +file descriptors 0, 1 and 2. Previously they were being closed which is
1.2421 +incorrect, in the embedded case. This led to weird behavior for programs
1.2422 +that want to interpose on I/O through the standard file descriptors (e.g.
1.2423 +Netscape Navigator). (JL)
1.2424 +
1.2425 +11/15/96 (bug fix) Fixed core dump on Windows sockets due to dependency on
1.2426 +deletion order at exit. Now all socket functions check to see if sockets
1.2427 +are (still) initialized, before calling through function pointers. Before,
1.2428 +they would call and might end up calling unloaded object code. (JL)
1.2429 +
1.2430 +11/15/96 (bug fix) Fixed core dump in Windows socket initialization routine
1.2431 +if sockets were not installed on the system. Before, it was not properly
1.2432 +checking the result of attempting to load the socket DLL, so it would call
1.2433 +through uninitialized function pointers. (JL)
1.2434 +
1.2435 +11/15/96 (bug fix) Fixed memory leak in Windows sockets which left socket
1.2436 +DLL handle open and could hold the socket DLL in memory uneccessarily,
1.2437 +until a reboot. (JL)
1.2438 +
1.2439 +12/4/96 (bug fix) Fixed bug in Macintosh socket code that could result
1.2440 +in lost data if a client was closed too soon after sending data. (RJ)
1.2441 +
1.2442 +12/17/96 (bug fix) Fixed deadlock bug in Windows sockets due to losing an
1.2443 +event. This was happening because of an interaction between buffering and
1.2444 +nonblocking mode on sockets. Now switched to sockets being blocking by
1.2445 +default, so we are also no longer emulating blocking through a private
1.2446 +event loop. (JL)
1.2447 +
1.2448 +1/21/97 (performance bug fix) Client TCP connections were slow to create
1.2449 +because getservbyname was always called on the port. Now this is only
1.2450 +done if Tcl_GetInt fails. (BW)
1.2451 +
1.2452 +1/21/97 (configuration fix) Made it possible to override TCL_PACKAGE_PATH
1.2453 +during make. Previously it was only set during autoconf process.
1.2454 +
1.2455 +1/29/97 (bug fix) Fixed some problems with the clock command that
1.2456 +impacted how dates were scaned after the year 2000. (RJ)
1.2457 +
1.2458 +----------------- Released 7.6p2, 1/31/97 -----------------------
1.2459 +
1.2460 +2/5/97 (bug fix) Fixed a bug where in CR-LF translation mode, \r bytes
1.2461 +in the input stream were not being handled correctly. (JL)
1.2462 +
1.2463 +2/24/97 (bug fix) Fix bug with exec under Win32s not being able to create
1.2464 +stderr file which caused all execs to fail. Fixed temp file leak under
1.2465 +Win32s. Fixed optional parameter bug with SearchPath that only happened
1.2466 +under Win32s 1.25. (CCS)
1.2467 +
1.2468 +----------------------------------------------------------
1.2469 +Changes for Tcl 7.6 go above this line.
1.2470 +Changes for Tcl 7.7 go below this line.
1.2471 +----------------------------------------------------------
1.2472 +
1.2473 +5/8/96 (new feature) Added Tcl_Ungets C API for putting a sequence of bytes
1.2474 +into a channel's input buffer. This can be used for "push" model channels
1.2475 +where the input is obtained via callbacks instead of by request of the
1.2476 +generic IO code. No Tcl procedure yet. (JL)
1.2477 +
1.2478 +11/15/96 (new feature) Implemented hidden commands. New C APIs:
1.2479 + Tcl_HideCommand -- hides an existing exposed command.
1.2480 + Tcl_ExposeCommand -- exposes an existing hidden command.
1.2481 +New tcl APIs:
1.2482 + interp invokehidden -- invokes a hidden command in a slave.
1.2483 + interp hide -- hides an existing exposed command.
1.2484 + interp expose -- exposes an existing hidden command.
1.2485 + interp hidden -- returns a list of hidden commands.
1.2486 +The implementation of Safe Tcl now uses the new hidden commands facility
1.2487 +to implement the safe base, instead of deleting the commands from a safe
1.2488 +interpreter. (JL)
1.2489 +
1.2490 +11/15/96 (new feature) Implemented the safe base, a mechanism for
1.2491 +installing and requesting security policies, purely in Tcl code. Overloads
1.2492 +the package command to also allow an interpreter to "require" a policy. The
1.2493 +following new library commands are provided:
1.2494 + tcl_safeCreateInterp -- creates a slave an initializes the
1.2495 + policy mechanism.
1.2496 + tcl_safeInitInterp -- initializes an existing slave with the
1.2497 + policy mechanism.
1.2498 + tcl_safeDeleteInterp -- deletes a slave and deinitializes the
1.2499 + policy mechanism.
1.2500 +Added a new file to the library, safeinit.tcl, to hold implementation. (JL)
1.2501 +On 7/9/97, removed the policy loading mechanism from the Safe Base. Left
1.2502 +only the Safe Base aliases dealing with auto-loading and source. (JL)
1.2503 +
1.2504 +12/6/96 (new feature) Implemented Tcl_Finalize, an API that should be
1.2505 +called by a process when it is done using Tcl. This API runs all the exit
1.2506 +handlers to allow them to clean up resources etc. (JL)
1.2507 +
1.2508 +12/17/96 (new feature) Add an http Tcl script package to the Tcl library.
1.2509 +This package implements the client side of HTTP/1.0; the GET, HEAD,
1.2510 +and POST requests. (BW)
1.2511 +
1.2512 +1/21/97 (new feature) Added a "marktrusted" subcommand to the "interp" and
1.2513 +to the interpreter object command. It removes the "safe" mark on an
1.2514 +interpreter and disables hard-wired checks for safety in the C sources. (JL)
1.2515 +
1.2516 +1/21/97 (removed feature) Removed "vwait" from set of commands available in
1.2517 +a safe interpreter. (JL)
1.2518 +
1.2519 +2/11/97 (new feature, bug fix) http package. Added -accept to http_config
1.2520 +so you can set the Accept header. Added -handler option to http_get so
1.2521 +you can supply your own data handler. Also fixed POST operation to
1.2522 +set the correct MIME type on the request. (BW)
1.2523 +
1.2524 +----------------------------------------------------------
1.2525 +Changes for Tcl 7.7 go above this line.
1.2526 +Changes for Tcl 8.0 go below this line.
1.2527 +----------------------------------------------------------
1.2528 +
1.2529 +9/17/96 (bug fix) Using "upvar" it was possible to turn an array element
1.2530 +into an array itself. Changed to disallow this; it was quirky and didn't
1.2531 +really work correctly anyway. (JO)
1.2532 +
1.2533 +10/21/96 (new feature) The core of the Tcl interpreter has been replaced
1.2534 +with an on-the-fly compiler that translates Tcl scripts to bytecoded
1.2535 +instructions; a new interpreter then executes the bytecodes. The compiler
1.2536 +introduces only a few minor changes at the level of Tcl scripts. The biggest
1.2537 +changes are to expressions and lists.
1.2538 + - A second level of substitutions is no longer done for expressions.
1.2539 + This substantially improves their execution time. This means that
1.2540 + the expression "$x*4" produces a different result than in the past
1.2541 + if x is "$y+2". Fortunately, not much code depends on the old
1.2542 + two-level semantics. Some expressions that do, such as
1.2543 + "expr [join $list +]" can be recoded to work in Tcl8.0 by adding
1.2544 + an eval: e.g., "eval expr [join $list +]".
1.2545 + - Lists are now completely parsed on the first list operation to
1.2546 + create a faster internal representation. In the past, if you had a
1.2547 + misformed list but the erroneous part was after the point you
1.2548 + inserted or extracted an element, then you never saw an error.
1.2549 + In Tcl8.0 an error will be reported. This should only effect
1.2550 + incorrect programs that took advantage of behavior of the old
1.2551 + implementation that was not documented in the man pages.
1.2552 +Other changes to Tcl scripts are discussed in the web page at
1.2553 +http://www.scriptics.com/doc/compiler.html. (BL)
1.2554 +*** POTENTIAL INCOMPATIBILITY ***
1.2555 +
1.2556 +10/21/96 (new feature) In earlier versions of Tcl, strings were used as a
1.2557 +universal representation; in Tcl 8.0 strings are replaced with Tcl_Obj
1.2558 +structures ("objects") that can hold both a string value and an internal
1.2559 +form such as a binary integer or compiled bytecodes. The new objects make it
1.2560 +possible to store information in efficient internal forms and avoid the
1.2561 +constant translations to and from strings that occurred with the old
1.2562 +interpreter. There are new many new C APIs for managing objects. Some of the
1.2563 +new library procedures for objects (such as Tcl_EvalObj) resemble existing
1.2564 +string-based procedures (such as Tcl_Eval) but take advantage of the
1.2565 +internal form stored in Tcl objects for greater speed. Other new procedures
1.2566 +manage objects and allow extension writers to define new kinds of objects.
1.2567 +See the manual entries doc/*Obj*.3 (BL)
1.2568 +
1.2569 +10/24/96 (bug fix) Fixed memory leak on exit caused by some IO related
1.2570 +data structures not being deallocated on exit because their refcount was
1.2571 +artificially boosted. (JL)
1.2572 +
1.2573 +10/24/96 (bug fix) Fixed core dump in Tcl_Close if called with NULL
1.2574 +Tcl_Channel. (JL)
1.2575 +
1.2576 +11/19/96 (new feature) Added library procedures for finding word
1.2577 +breaks in strings in a platform specific manner. See the library.n
1.2578 +manual entry for more information. (SS)
1.2579 +
1.2580 +11/22/96 (feature improvements) Added support for different levels of
1.2581 +tracing during bytecode compilation and execution. This should help in
1.2582 +tracking down suspected problems with the compiler or with converting
1.2583 +existing code to use Tcl8.0. Two global Tcl variables, traceCompile
1.2584 +and traceExec, can be set to generate tracing information in stdout:
1.2585 + - traceCompile: 0 no tracing (default)
1.2586 + 1 trace compilations of top level commands and procs
1.2587 + 2 trace and display instructions for all compilations
1.2588 + - traceExec: 0 no tracing
1.2589 + 1 trace only calls to Tcl procs
1.2590 + 2 trace invocations of all commands including procs
1.2591 + 3 detailed trace showing the result of each instruction
1.2592 +traceExec >= 2 provides a one line summary of each called command and
1.2593 +its arguments. Commands that have been "compiled away" such as set are
1.2594 +not shown. (BL)
1.2595 +
1.2596 +11/30/96 (bug fix) The command "info nameofexecutable" could sometimes
1.2597 +return the name of a directory. (JO)
1.2598 +
1.2599 +11/30/96 (feature improvements) Changed the code in library/init.tcl
1.2600 +that reads in pkgIndex.tcl so that (a) it reads the files from child
1.2601 +directories before those in the parent, so that the parent gets
1.2602 +precedence, and (b) it doesn't quit if there is an error in a
1.2603 +pkgIndex.tcl file; instead, it prints an error message on standard
1.2604 +error and continues. (JO)
1.2605 +
1.2606 +10/5/96 (feature improvements) Partial implementation of binary string
1.2607 +support: the ability for Tcl string values to contain embedded null bytes.
1.2608 +Changed the Tcl object-based APIs to take a byte pointer and length pair
1.2609 +instead of a null-terminated C string. Modified several object type managers
1.2610 +to support binary strings but not, for example, the list type manager.
1.2611 +Existing string-based C APIs are unchanged and will truncate binary
1.2612 +strings. Compiled scripts containing nulls are also truncated. (BL)
1.2613 +
1.2614 +12/12/96 (feature change) Removed the commands "cp", "mkdir", "mv",
1.2615 +"rm", and "rmdir" from the Macintosh version of Tcl. They were never
1.2616 +officially supported and their functionality is now available via
1.2617 +the file command. (RJ)
1.2618 +
1.2619 +----------------- Released 8.0a1, 12/20/96 -----------------------
1.2620 +
1.2621 +1/7/97 (bug fix) Under Windows, "file stat c:" was returning error instead
1.2622 +of stat for current dir on c: drive.
1.2623 +
1.2624 +1/10/97 (new feature) Added Tcl_GetIndexFromObj procedure for quick
1.2625 +lookups of keyword arguments. (JO)
1.2626 +
1.2627 +1/12/97 (new feature) Serial IO channel drivers for Windows and Unix,
1.2628 +available by using Tcl open command to open pseudo-files like "com1:" or
1.2629 +"/dev/ttya". New option to Tcl fconfigure command for serial files:
1.2630 +"-mode baud,parity,data,stop" to specify baud rate, parity, data bits, and
1.2631 +stop bits. Serial IO is not yet available on Mac.
1.2632 +
1.2633 +1/16/97 (feature change) Restored the Tcl7.x "two level substitution
1.2634 +semantics" for expressions. Expressions not enclosed in braces are
1.2635 +implemented, in general, by calling the expr command procedure
1.2636 +(Tcl_ExprObjCmd) at runtime after the Tcl interpreter has already done a
1.2637 +first round of substitutions. This is slow (about Tcl7.x speed) because new
1.2638 +code for the expression is generally compiled each time. However, if the
1.2639 +expression has only variable substitutions (and not command substitutions),
1.2640 +"optimistic" fast code is generated inline. This inline code will fail if a
1.2641 +second round of substitutions is needed (i.e., if the value of a substituted
1.2642 +variable itself requires more substitutions). The optimistic code will
1.2643 +catch the error and back off to call the slower but guaranteed correct
1.2644 +expr command procedure. (BL)
1.2645 +
1.2646 +1/16/97 (feature improvements) Added Tcl_ExprLongObj and Tcl_ExprDoubleObj
1.2647 +to round out expression-related procedures. (BL)
1.2648 +
1.2649 +1/16/97 (feature change) Under Windows, at startup the environment variables
1.2650 +"path", "comspec", and "windir" in any capitalization are converted
1.2651 +automatically to upper case. The PATH variable could be spelled as path,
1.2652 +Path, PaTh, etc. and it makes programming rather annoying. All other
1.2653 +environment variables are left alone. (CS)
1.2654 +
1.2655 +1/20/97 (new features) Rewrote the "lsort" command:
1.2656 + - The new version is based on reentrant merge sort code provided
1.2657 + by Richard Hipp, so it eliminates the reentrancy and stability
1.2658 + problems with the old qsort-based implementation.
1.2659 + - The new version supports a -dictionary option for sorting, and
1.2660 + it also supports a -index option for sorting lists using one
1.2661 + element for comparison.
1.2662 + - The new version is an object command, so it works well with the
1.2663 + Tcl compiler, especially in conjunction with the new -index
1.2664 + option. When the -index option is used, this version of lsort
1.2665 + is more than 100 times faster than the Tcl 7.6 lsort, which had
1.2666 + to use the -command option to get the same effect. (JO)
1.2667 +
1.2668 +1/20/97 (feature improvements) Added the improved debugging support for Tcl
1.2669 +objects prototyped by Karl Lehenbauer <karl@hammer1.ops.NeoSoft.com>.
1.2670 +If TCL_MEM_DEBUG is defined, the object creation calls use Tcl_DbCkalloc
1.2671 +directly in order to record the caller's source file name and line
1.2672 +number. (BL)
1.2673 +
1.2674 +1/21/97 (removed feature) Desupported the tcl_precision variable: if
1.2675 +set, it is ignored. Tcl now uses the full 17 digits of precision when
1.2676 +converting real numbers to strings (with the new object system real
1.2677 +numbers are rarely converted to strings so there is no efficiency
1.2678 +disadvantage to printing all 17 digits; the new scheme improves
1.2679 +accuracy and simplifies several APIs). (JO)
1.2680 +*** POTENTIAL INCOMPATIBILITY ***
1.2681 +
1.2682 +1/21/97 (feature change) Removed the "interp" argument for the
1.2683 +procedures Tcl_GetStringFromObj, Tcl_StringObjAppend, and
1.2684 +Tcl_StringObjAppendObj. Also removed the "interp" argument for
1.2685 +the updateStringProc procedure in Tcl_ObjType structures. With
1.2686 +the tcl_precision changes above, these are no longer needed. (JO)
1.2687 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a1, but not with Tcl 7.6 ***
1.2688 +
1.2689 +1/22/97 (bug fix) Fixed http.tcl so that http_reset does not result in
1.2690 +an extra call to the command callback. In addition, if the transaction
1.2691 +gets a premature eof, the state(status) is "eof", not "ok". (BW)
1.2692 +
1.2693 +----------------- Released 8.0a2, 1/24/97 -----------------------
1.2694 +
1.2695 +1/29/97 (feature change) Changed how two digit years are parsed in the
1.2696 +clock command. The old interface just added 1900 which will seem
1.2697 +broken by the year 2000. The new scheme follows the POSIX standard
1.2698 +and treats dates 70-99 as 1970-1999 and dates 00-38 as 2000-2038. All
1.2699 +other two digit dates are undefined. (RJ)
1.2700 +*** POTENTIAL INCOMPATIBILITY ***
1.2701 +
1.2702 +2/4/97 (bug fix) Fixed bug in clock code that dealt with relative
1.2703 +dates. Using the relative month code you could get an invalid date
1.2704 +because it jumped into a non-existant day. (For example, Jan 31
1.2705 +to Feb 31.) The code now will return the last valid day of the
1.2706 +month in these situations. Thanks to Hume Smith for sending in
1.2707 +this bug fix. (RJ)
1.2708 +
1.2709 +2/10/97 (feature change) Eliminated Tcl_StringObjAppend and
1.2710 +Tcl_StringObjAppendObj procedures, replaced them with Tcl_AppendToObj
1.2711 +and Tcl_AppendStringsToObj procedures. Added new procedure
1.2712 +Tcl_SetObjLength. (JO)
1.2713 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2, but not with Tcl 7.6 ***
1.2714 +
1.2715 +2/10/97 (new feature) Added Tcl_WrongNumArgs procedure for generating
1.2716 +error messages about incorrect number of arguments. (JO)
1.2717 +
1.2718 +2/11/97 (new feature, bug fix) http package. Added -accept to http_config
1.2719 +so you can set the Accept header. Added -handler option to http_get so
1.2720 +you can supply your own data handler. Also fixed POST operation to
1.2721 +set the correct MIME type on the request. (BW)
1.2722 +
1.2723 +2/22/97 (bug fix) Fixed bug that caused $tcl_platform(osVersion) to be
1.2724 +computed incorrectly under AIX. (JO)
1.2725 +
1.2726 +2/25/97 (new feature, feature change) Added support for both int and long
1.2727 +integer objects. Added Tcl_NewLongObj/Tcl_GetLongFromObj/Tcl_SetLongFromObj
1.2728 +procedures and renamed the Tcl_Obj internalRep intValue member to
1.2729 +longValue. Tcl_GetIntFromObj now checks for integer values too large to
1.2730 +represent as non-long integers. Changed Tcl_GetAllObjTypes to
1.2731 +Tcl_AppendAllObjTypes. (BL)
1.2732 +
1.2733 +3/5/97 (new feature) Added new Tcl_SetListObj procedure to round out
1.2734 +collection of procedures that set the type and value of existing Tcl
1.2735 +objects. (BL)
1.2736 +
1.2737 +3/6/97 (new feature) Added -global flag for interp invokehidden. (JL)
1.2738 +
1.2739 +3/6/97 (new feature, feature change) Added isNativeObjectProc field to the
1.2740 +Tcl_CmdInfo structure to indicate (when 1) if the command has an
1.2741 +object-based command procedure. Removed the nameLength arg from
1.2742 +Tcl_CreateObjCommand since command names can't contain null characters. (BL)
1.2743 +
1.2744 +3/6/97 (bug fix) Fixed bug in "unknown" procedure that caused auto-
1.2745 +loading to fail on commands whose names begin with digits. (JO)
1.2746 +
1.2747 +3/7/97 (bug fix) Auto-loading now works in Safe Base. Safe interpreters
1.2748 +only accept the Version 2 and onwards tclIndex files. (JL)
1.2749 +
1.2750 +3/13/97 (bug fix) Fixed core dump due to interaction between aliases and
1.2751 +hidden commands. Bug found by Lindsay Marshall. (JL)
1.2752 +
1.2753 +3/14/97 (bug fix) Fixed mac bugs relating to time. The -gmt option
1.2754 +now adjusts the time in the correct direction. (Thanks to Ed Hume for
1.2755 +reporting a fix to this problem.) Also fixed file "mtime" etc. to
1.2756 +return times from GMT rather than local time zone. (RJ)
1.2757 +
1.2758 +3/18/97 (feature change) Declaration of objv in Tcl_ObjCmdProc function
1.2759 +changed from "Tcl_Obj *objv[]" to "Tcl_Obj *CONST objv[]". All Tcl object
1.2760 +commands changed to use new declaration of objv. Naive translation of
1.2761 +string-based command procs to object-based command procs could very easily
1.2762 +have yielded code where the contents of the objv array were changed. This
1.2763 +is not a problem with string-based command procs, but doing something as
1.2764 +simple as objv[2] = objv[3] would corrupt the runtime stack and cause Tcl to
1.2765 +crash. Introduced CONST in declaration of objv so that attempted assignment
1.2766 +of new pointer values to elements of the objv array will be caught by the
1.2767 +compiler. (CCS)
1.2768 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 ***
1.2769 +
1.2770 +3/19/97 (bug fix) Fixed panic due to object sharing. The root cause was
1.2771 +that old code was using Tcl_ResetResult instead of Tcl_ResetObjResult. (JL)
1.2772 +
1.2773 +3/20/97 (new feature) Added a new subcommand for the file
1.2774 +command. file attributes filename can give a list of platform-specific
1.2775 +options (such as file/creator type on the Mac, permissions on Unix) or
1.2776 +set the values of them. Added a new subcommand for the file
1.2777 +command. file nativename name gives back the platform-specific form
1.2778 +for the file. This is useful when the filename is needed to pass to
1.2779 +the OS, such as exec under Windows 95 or AppleScript on the Mac. For
1.2780 +more info, see file.n. (SRP)
1.2781 +
1.2782 +3/24/97 (removed feature) Removed the tcl_safePolicyPath procedure. Now
1.2783 +the policy path is computed from the auto_path by appending the directory
1.2784 +'policies' to each element. Also fixed several bugs in automatic tracking
1.2785 +of auto_path by computed policy path. (JL)
1.2786 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 ***
1.2787 +
1.2788 +4/8/97 (new feature) If the variable whose name is passed to lappend doesn't
1.2789 +already exist, and there are no value arguments, lappend now creates the
1.2790 +variable with an empty value instead of returning an error. Change suggested
1.2791 +by Tom Tromey. (BL)
1.2792 +
1.2793 +4/9/97 (feature change) Changed the name of the TCL_PART1_NOT_PARSED flag to
1.2794 +TCL_PARSE_PART1. (BL)
1.2795 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 ***
1.2796 +
1.2797 +4/10/97 (bug fixes) Fixed various compilation-related bugs:
1.2798 + - "UpdateStringOfCmdName should never be invoked" panic.
1.2799 + - Bad code generated for expressions not in {}'s inside catch commands.
1.2800 + - Segmentation fault in some command procedures when two argument
1.2801 + object pointers refer to the same object.
1.2802 + - Second level of substitutions were never done for expressions not
1.2803 + in {}'s that consist of a single variable reference: e.g.,
1.2804 + "set x 27; set bool {$x}; if $bool {puts foo}" would fail with error.
1.2805 + - Bad code generated when code storage was grown while compiling some
1.2806 + expressions: ones with compilation errors or consisting of only a
1.2807 + variable reference.
1.2808 + - Bugs involving multiple interpreters: wasn't checking that a
1.2809 + procedure's code was compiled for the same interpreter as the one
1.2810 + executing it, and didn't invalidate code on hidden-exposed command
1.2811 + transitions.
1.2812 + - "Bad stack top" panic when executing scripts that require a huge
1.2813 + amount of stack space.
1.2814 + - Incorrect sharing of code for procedure bodies, and procedure code
1.2815 + deallocated before last execution of the procedure finished.
1.2816 + - Fixed compilation of expression words in quotes. For example,
1.2817 + if "0 < 3" {puts foo}.
1.2818 + - Fixed performance bug in array set command with large assignments.
1.2819 + - Tcl_SetObjLength segmentation fault setting length of empty object.
1.2820 + - If Tcl_SetObjectResult was passed the same object as the interpreter's
1.2821 + result object, it freed the object instead of doing nothing. Bug fix
1.2822 + by Michael J. McLennan.
1.2823 + - Tcl_ListObjAppendList inserted elements from the wrong list. Bug fix
1.2824 + by Michael J. McLennan.
1.2825 + - Segmentation fault if empty variable list was specified in a foreach
1.2826 + command. Bug fix by Jan Nijtmans.
1.2827 + - NULL command name was always passed to Tcl_CreateTrace callback
1.2828 + procedure.
1.2829 + - Wrong string representation generated for the value LONG_MIN.
1.2830 + For example, expr 1<<31 printed incorrectly on a 32 bit machine.
1.2831 + - "set {a($x)} 1" stored value in wrong variable.
1.2832 + - Tcl_GetBooleanFromObj was not checking for garbage after a numeric
1.2833 + value.
1.2834 + - Garbled "bad operand type" error message when evaluating expressions
1.2835 + not surrounded by {}'s. (BL)
1.2836 +
1.2837 +4/16/97 (new feature) The expr command now has the "rand()" and
1.2838 +"srand()" functions for getting random numbers in expr. (RJ)
1.2839 +
1.2840 +4/23/97 (bug fix) Fixed core dump in bgerror when the error handler command
1.2841 +deletes the current interpreter. Found by Juergen Schoenwald. (JL)
1.2842 +
1.2843 +4/23/97 (feature change) The notifier interfaces have been redesigned
1.2844 +to make embedding in applications with external event loops possible.
1.2845 +A number of interfaces in the notifier and the channel drivers have
1.2846 +changed. Refer to the Notifier.3 and CrtChannel.3 manual entries for

1.2848 +*** POTENTIAL INCOMPATIBILITY ***
1.2849 +
1.2850 +4/23/97 (removed feature) The Tcl_File interfaces have been removed.
1.2851 +The Tcl_CreateFileHandler/Tcl_DeleteFileHandler interfaces now take
1.2852 +Unix fd's and are only supported on the Unix platform.
1.2853 +Tcl_GetChannelFile has been replaced with Tcl_GetChannelHandle.
1.2854 +Tcl_MakeFileChannel now takes a platform specific file handle. (SS)
1.2855 +*** POTENTIAL INCOMPATIBILITY ***
1.2856 +
1.2857 +4/23/97 (removed feature) The modal timeout interface has been

1.2859 +*** POTENTIAL INCOMPATIBILITY ***
1.2860 +
1.2861 +4/23/97 (feature change) Channel drivers are now required to correctly

1.2863 +*** POTENTIAL INCOMPATIBILITY ***
1.2864 +
1.2865 +4/23/97 (new feature) Added the "binary" command for manipulating
1.2866 +binary strings. Also, changed the "puts", "gets", and "read" commands
1.2867 +to preserve embedded nulls. (SS)
1.2868 +
1.2869 +4/23/97 (new feature) Added tcl_platform(byteOrder) element to the

1.2871 +host. (SS)
1.2872 +
1.2873 +4/23/97 (bug fix) Fixed bug in date parsing around year boundaries. (SS)
1.2874 +
1.2875 +4/24/97 (bug fix) In the process of copying a file owned by another user,
1.2876 +Tcl was changing the owner of the copy back to the owner of the original
1.2877 +file, therefore causing further file operations to fail because the current
1.2878 +user didn't own the copy anymore. The owner of the copy is now left as the
1.2879 +current user. (CCS)
1.2880 +
1.2881 +4/24/97 (feature change) Under Windows, don't automatically uppercase the
1.2882 +environment variable "windir" -- it's supposed to be lower case. (CCS)
1.2883 +
1.2884 +4/29/97 (new feature) Added namespace support based on a namespace
1.2885 +implementation by Michael J. McLennan of Lucent Technologies. A namespace
1.2886 +encapsulates a collection of commands and variables to ensure that they
1.2887 +won't interfere the commands and variables of other namespaces. The global
1.2888 +namespace holds all global variables and commands. Additional namespaces are
1.2889 +created with the new namespace command. The new variable command lets you
1.2890 +create Tcl variables inside a namespace. The names of Tcl variables and
1.2891 +commands may now be qualified by the name of the namespace containing them.
1.2892 +The key namespace-related commands are summarized below:
1.2893 + - namespace ?eval? name arg ?arg...?
1.2894 + Used to define the commands and variables in a namespace.
1.2895 + Optionally creates the namespace.
1.2896 + - namespace export ?-clear? ?pattern pattern...?
1.2897 + Specifies which commands are exported from a namespace. These
1.2898 + are the ones that can be imported into another namespace.
1.2899 + - namespace import ?-force? ?pattern pattern...?
1.2900 + Makes the specified commands accessible in the current namespace.
1.2901 + - namespace current
1.2902 + Returns the name of the current namespace.
1.2903 + - variable name ?value? ?name ?value?...?
1.2904 + Creates one or more namespace variables. (BTL)
1.2905 +
1.2906 +5/1/97 (bug fix) Under Windows, file times were reported in GMT. Should be
1.2907 +reported in local time. (CCS)
1.2908 +
1.2909 +5/2/97 (feature change) Changed the name of the two Tcl variables used for
1.2910 +tracing bytecode compilation and execution to tcl_traceCompile and
1.2911 +tcl_traceExec respectively. These variables are now documented in the
1.2912 +tclvars man page. (BL)
1.2913 +
1.2914 +5/5/97 (new feature) Support "end" as the index for "lsort -index". (BW)
1.2915 +
1.2916 +5/5/97 (bug fixes) Cleaned up the way the http package resets connections (BW)
1.2917 +
1.2918 +5/8/97 (feature change) Newly created Tcl objects now have a reference count
1.2919 +of zero instead of one. This simplifies C code that stores newly created
1.2920 +objects in Tcl variables or in data structures such as list objects. That C
1.2921 +code must increment the new object's reference count since the variable or
1.2922 +data structure will contain a long-term reference to the object. Formerly,
1.2923 +when new objects started out with reference count one, it was necessary to
1.2924 +decrement the new object's reference count after the store to make sure it
1.2925 +was left with the correct value; this is no longer necessary. (BL)
1.2926 +
1.2927 +5/9/97 (new feature) Added the Tcl_GetsObj interface that takes an
1.2928 +object reference instead of a dynamic string (as in Tcl_Gets). (SS)
1.2929 +
1.2930 +5/12/97 (new feature) Added Tcl_CreateAliasObj and Tcl_GetAliasObj C APIs
1.2931 +to allow an alias command to be created with a vector of Tcl_Obj structures
1.2932 +and to get the vector back later. (JL)
1.2933 +
1.2934 +5/12/97 (feature change) Changed Tcl_ExposeCommand and Tcl_HideCommand to
1.2935 +leave an object result instead of a string result. (JL)
1.2936 +
1.2937 +5/14/97 (feature change) Improved the handling of the interpreter result.
1.2938 +This is still either an object or a string, but the two values are now kept
1.2939 +consistent unless some C code reads or writes interp->result directly. See
1.2940 +the SetResult man page for details. Removed the Tcl_ResetObjResult
1.2941 +procedure. (BL)
1.2942 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 ***
1.2943 +
1.2944 +5/16/97 (new feature) Added "fcopy" command to move data between
1.2945 +channels. Refer to the manual page for more information. Removed the
1.2946 +"unsupported0" command since it is obsolete now. (SS)
1.2947 +
1.2948 +5/16/97 (new feature) Added Tcl_GetStringResult procedure to allow programs
1.2949 +to get an interpreter's result as a string. If the result was previously set
1.2950 +to an object, this procedure will convert the object to a string. Use of
1.2951 +Tcl_GetStringResult is intended to replace direct access to interp->result,
1.2952 +which is not safe. (BL)
1.2953 +
1.2954 +5/20/97 (new features) Fixed "fcopy" to return the number of bytes
1.2955 +transferred in the blocking case. Updated the http package to use
1.2956 +fcopy instead of unsupported0. Added -timeout and -handler options to
1.2957 +http_get. http_get is now blocking by default. It is only non-blocking
1.2958 +if you supply a -command argument. (BW)
1.2959 +
1.2960 +5/22/97 (bug fix) Fixed several bugs in the "lsort" command having to do
1.2961 +with the -dictionary option and the presence of numbers embedded in the
1.2962 +strings. (JO)
1.2963 +
1.2964 +----------------- Released 8.0b1, 5/27/97 -----------------------
1.2965 +
1.2966 +6/2/97 (bug fix) Fixed bug in startup code that caused a problem in
1.2967 +finding the library files when they are installed in a directory
1.2968 +containing a space in the name. (SS)
1.2969 +
1.2970 +6/2/97 (bug fix) Fixed bug in Unix notifier where the select mask was
1.2971 +not being cleared under some circumstances. (SS)
1.2972 +
1.2973 +6/4/97 (bug fix) Fixed bug that prevented creation of Tk widgets in
1.2974 +namespaces. Tcl_CreateObjCommand and Tcl_CreateCommand now always create
1.2975 +commands in the global namespace unless the command names are qualified. Tcl
1.2976 +procedures continue to be created in the current namespace by default. (BL)
1.2977 +
1.2978 +6/6/97 (new features) Added new namespace API procedures
1.2979 +Tcl_AppendExportList and Tcl_Export to allow C code to get and set a
1.2980 +namespace's export list. (BL)
1.2981 +
1.2982 +6/11/97 (new feature) Added Tcl_ConcatObj. This object-based routine
1.2983 +parallels the string-based routine Tcl_Concat. (SRP)
1.2984 +
1.2985 +6/11/97 (new feature) Added Tcl_SetObjErrorCode. This object-based
1.2986 +routines parallels the string-based routine Tcl_SetErrorCode. (SRP)
1.2987 +
1.2988 +6/12/97 (bug fix) Fix the "unknown" procedure so that wish under Windows
1.2989 +will exec an external program, instead of always complaining "console1 not
1.2990 +opened for writing". (CCS)
1.2991 +
1.2992 +6/12/97 (bug fix) Fixed core dump experienced by the following simple
1.2993 +script:
1.2994 + interp create x
1.2995 + x alias exec exec
1.2996 + interp delete x
1.2997 +This panic was caused by not installing the new CmdDeleteProc when exec
1.2998 +got redefined by the alias creation step. Reported by Lindsay Marshal (JL)
1.2999 +
1.3000 +6/13/97 (new features) Tcl objects newly created by Tcl_NewObj now have a
1.3001 +string representation that points to a shared heap string of length 1. (They
1.3002 +used to have NULL bytes and typePtr fields. This was treated as a special
1.3003 +case to indicate an empty string, but made type manager implementations
1.3004 +complex and error prone.) The new procedure Tcl_InvalidateStringRep is used
1.3005 +to mark an object's string representation invalid and to free any storage
1.3006 +associated with the old string representation. (BL)
1.3007 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 ***
1.3008 +
1.3009 +6/16/97 (bug fix) Tcl_ScanCountedElement could leave braces unmatched
1.3010 +if the string ended with a backslash. (JO)
1.3011 +
1.3012 +6/17/97 (bug fix) Fixed channel event bug where readable events would be
1.3013 +lost during recursive events loops if the input buffers contained
1.3014 +data. (SS)
1.3015 +
1.3016 +6/17/97 (bug fix) Fixed bug in Windows socket code that didn't
1.3017 +reenable read events in the case where an external entity is also
1.3018 +reading from the socket. (SS)
1.3019 +
1.3020 +6/18/97 (bug fix) Changed initial setting of the notifier service mode
1.3021 +to TCL_SERVICE_NONE to avoid unexpected event handling during
1.3022 +initialization. (SS)
1.3023 +
1.3024 +6/19/97 (bug fix/feature change) The command callback to fcopy is now
1.3025 +called in case of errors during the background copy. This adds a second,
1.3026 +optional argument to the callback that is the error string. The callback
1.3027 +in case of errors is required for proper cleanup by the user of fcopy. (BW)
1.3028 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
1.3029 +
1.3030 +6/19/97 (bug fix) Fixed a panic due to the following four line script:
1.3031 + interp create x
1.3032 + x alias foo bar
1.3033 + x eval rename foo blotz
1.3034 + x alias foo {}
1.3035 +The problem was that the interp code was not using the actual current name
1.3036 +of the command to be deleted as a result of un-aliasing foo. (JL)
1.3037 +
1.3038 +6/19/97 (feature change) Pass interp down to the ChannelOption and
1.3039 +driver specific calls so system errors can be differentiated from syntax
1.3040 +ones. Changed Tcl_DriverGetOptionProc type. Affects Tcl_GetChannelOption,
1.3041 +TcpGetOptionProc, TtyGetOptionProc, etc. (DL)
1.3042 +*** POTENTIAL INCOMPATIBILITY ***
1.3043 +
1.3044 +6/19/97 (new feature) Added Tcl_BadChannelOption for use by by driver
1.3045 +specific option procedures (Set and Get) to return a complete and
1.3046 +meaningful error message. (DL)
1.3047 +
1.3048 +6/19/97 (bug fixes) If a system call error occurs while doing an
1.3049 +fconfigure on tcp or tty/com channel: return the appropriate error
1.3050 +message (instead of the syntax error one or none). (Fixed for Unix and
1.3051 +most of the Win and Mac drivers). (DL)
1.3052 +
1.3053 +6/20/97 (feature change) Eval is no longer assumed as the subcommand name
1.3054 +in namespace commands: you must now write "namespace eval nsName {...}".
1.3055 +Abbreviations of namespace subcommand names are now allowed. (BL)
1.3056 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 ***
1.3057 +
1.3058 +6/20/97 (feature change) Changed the errorInfo traceback message for
1.3059 +compilation errors from "invoked from within" to "while compiling". (BL)
1.3060 +
1.3061 +6/20/97 (bug fixes) Fixed various compilation-related bugs:
1.3062 + - "UpdateStringOfCmdName should never be called" and
1.3063 + "UpdateStringOfByteCode should never be called" panics.
1.3064 + - Segfault in TclObjInterpProc getting procedure name after evaluation
1.3065 + stack is reallocated (grown).
1.3066 + - Could not use ":" at end of variable and command names.
1.3067 + - Bad code generated for while and for commands with test expressions
1.3068 + enclosed in quotes: e.g., "set i 0; while "$i > 5" {}".
1.3069 + - Command trace procedures would crash if they did a Tcl_EvalObj that
1.3070 + reallocated the evaluation stack.
1.3071 + - Break and continue commands did not reset the interpreter result.
1.3072 + - The Tcl_ExprXXX routines, both string- or object-based, always
1.3073 + modified the interpreter result even if there was no error.
1.3074 + - The argument parsing procedure used by several compile procedures
1.3075 + always treated "]" as end of a command: e.g., "set a ]" would fail.
1.3076 + - Changed errorInfo traceback message for compilation errors from
1.3077 + "invoked from within" to "while compiling".
1.3078 + - Problem initializing Tcl object managers during interpreter creation.
1.3079 + - Added check and error message if formal parameter to a procedure is
1.3080 + an array element. (BL)
1.3081 +
1.3082 +6/23/97 (new feature) Added "registry" package to allow manipulation
1.3083 +of the Windows system registry. See manual entry for details. (SS)
1.3084 +
1.3085 +6/24/97 (feature change) Converted http to a package and added the
1.3086 +http1.0 subdirectory of the Tcl script library. This means you have
1.3087 +to do a "package require http" to use this, as advertised in the man page. (BW)
1.3088 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
1.3089 +
1.3090 +6/24/97 (bug fix) Ensure that Tcl_Set/GetVar C APIs, when called without
1.3091 +TCL_LEAVE_ERR_MSG, don't touch the interp result. (DL)
1.3092 +
1.3093 +6/26/97 (feature change) Changed name of Tcl_ExprStringObj to
1.3094 +Tcl_ExprObj. (BL)
1.3095 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
1.3096 +
1.3097 +----------------- Released 8.0b2, 6/30/97 -----------------------
1.3098 +
1.3099 +7/1/97 (new feature) TCL_BUILD_SHARED flag set in tclConfig.sh
1.3100 +when Tcl has been built with --enable-shared. A new tclLibObjs
1.3101 +make target, echoing the list of the .o's needed to build a tcl
1.3102 +library, is now provided. (DL)
1.3103 +
1.3104 +7/1/97 (feature change) compat/getcwd.c removed and changed the
1.3105 +only place where getcwd is used so a new USEGETWD flag selects
1.3106 +the use of the replacement "getwd". Adding this flag is recommended
1.3107 +for SunOS 4 (because getcwd on SunOS 4 uses a pipe to pwd(1)!). (DL)
1.3108 +
1.3109 +7/7/97 (feature change) The split command now supports binary data (i.e.,
1.3110 +null characters in strings). (BL)
1.3111 +
1.3112 +7/7/97 (bug fix) string first returned the wrong result if the first
1.3113 +argument string was empty. (BL)
1.3114 +
1.3115 +7/8/97 (bug fix) Fixed core dump in fcopy that could occur when a command
1.3116 +callback was supplied and an error or eof condition caused no background
1.3117 +activity. A refcount bug triggered a panic in Tcl_ListObjAppendElement. (BW)
1.3118 +
1.3119 +7/8/97 (bug fix) Relaxed the pattern matching on http_get so you do not
1.3120 +need a trailing path component. You can now get away with just
1.3121 +http_get www.scriptics.com (BW)
1.3122 +
1.3123 +7/9/97 (bug fix) Creating anonymous interpreters no longer smashes existing
1.3124 +commands with names similar to the generated name. Previously creating an
1.3125 +anonymous interpreter could smash an existing command, now it skips until
1.3126 +it finds a command name that isn't being used. (JL)
1.3127 +
1.3128 +7/9/97 (feature change) Removed the policy management mechanism from the
1.3129 +Safe Base; left the aliases to source and load modules, and to do a limited
1.3130 +form of the "file" command. See entry of 11/15/96. (JL)
1.3131 +
1.3132 +7/9/97 (bug fixes) Fixed various compilation-related bugs:
1.3133 + - Line numbers in errorInfo now are the same as those in Tcl7.6 unless
1.3134 +there are compilation errors. Compilation error messages now include the
1.3135 +entire command in error.
1.3136 + - Trailing ::s after namespace names weren't being ignored.
1.3137 + - Could not refer to an namespace variable with an empty name using a
1.3138 +name of the form "n::". (BL)
1.3139 +
1.3140 +7/9/97 (bug fix) Fixed bug in Tcl_Export that prevented you from exporting
1.3141 +from other than the current namespace. (BL)
1.3142 +
1.3143 +7/9/97 (bug fix) env.test was removing env var needed for proper finding
1.3144 +of libraries in child process. (DL)
1.3145 +
1.3146 +7/10/97 (bug fixes/new feature) Cleanup in Tcl_MakeSafe. Less information
1.3147 +is leaked to safe interps. Error message fixes for interp sub commands.
1.3148 +Likewise changes in safealias.tcl; tcl_safeCreateInterp can now be called
1.3149 +without argument to generate the slave name (like in interp create). (DL)
1.3150 +
1.3151 +7/10/97 (bug fixes) Bytecode compiler now generates more detailed
1.3152 +command location information: subcommands as well as commands now have
1.3153 +location information. This means command trace procedures now get the
1.3154 +correct source string for each command in their command parameter. (BL)
1.3155 +
1.3156 +7/22/97 (bug fixes) Performance improvement in Safe interpreters
1.3157 +handling. Added new mask value to (tclInt.h) Interp.flags record. (DL)
1.3158 +
1.3159 +7/22/97 (bug fix) Fixed panic in 'interp target {} foo'. This bug
1.3160 +was present since Tcl 7.6. (JL)
1.3161 +
1.3162 +7/22/97 (bug fix) Fixed bug in compilation of procedures in namespaces: the
1.3163 +procedure's namespace must be used to look up compile procedures, not the
1.3164 +current namespace. (BL)
1.3165 +
1.3166 +7/22/97 (bug fix) Use of the -channel option of http_get was not setting
1.3167 +the end of line translations mode on the channel, so copying binary data
1.3168 +with the -channel option was corrupting the result on non-unix platforms. (BW)
1.3169 +
1.3170 +7/22/97 (bug fixes) file commands and ~user (seg fault and other
1.3171 +improper returns). (DL)
1.3172 +
1.3173 +7/23/97 (feature change) Reenabled "vwait" in Safe Base. (JL)
1.3174 +
1.3175 +7/23/97 (bug fixes) Fixed two bugs involving read traces on array variables
1.3176 +in procedures: trace procedures were sometimes not called, and reading
1.3177 +nonexistant array elements didn't create undefined element variables that
1.3178 +could later be defined by trace procedures. (BL)
1.3179 +
1.3180 +7/24/97 (bug fix) Windows memory allocation performance was
1.3181 +superlinear in some cases. Made the Mac allocator generic and changed
1.3182 +both the Mac and Windows platforms to use the new allocator instead of
1.3183 +malloc and free. (SS)
1.3184 +
1.3185 +7/24/97 - 8/12/97 (bug fixes/change of features) Completely revamped safe
1.3186 +sourcing/loading (see safe.n) to hide pathnames, use virtual
1.3187 +paths tokens instead, improved security in several respects and made it
1.3188 +more tunable. Multi level interp loading can work too now. Package auto
1.3189 +loading now works in safe interps as long as the package directory is in
1.3190 +the auto_path (no deep crawling allowed in safe interps). (DL)
1.3191 +*** POTENTIAL INCOMPATIBILITY with previous alpha and beta releases ***
1.3192 +
1.3193 +7/24/97 (bug fixes) Made Tcl_SetVar* and Tcl_NewString* treat a NULL value
1.3194 +as an empty string. (This fixes hairy crash case where you would crash
1.3195 +because load command for other interps assumed presence of
1.3196 +errorInfo...). (DL)
1.3197 +
1.3198 +7/28/97 (bug fix) Fixed pkg_mkIndex to understand namespaces. It will
1.3199 +use the export list of a namespace and create auto_index entries for
1.3200 +all export commands. Those names are in their fully qualified form in the
1.3201 +auto_index. Therefore, I tweaked unknown to try both $cmd and ::$cmd.
1.3202 +Also fixed pkg_mkIndex so you can have "package require" commands inside
1.3203 +your packages. These commands are ignored, which is mostly ok except
1.3204 +when you must load another package before loading yours because of
1.3205 +linking dependencies. (BW)
1.3206 +
1.3207 +7/28/97 (bug fix) A variable created by the variable command now persists
1.3208 +until the namespace is destroyed or the variable is unset. This is true even
1.3209 +if the variable has not been initialized; these variables used to be
1.3210 +destroyed if an error occurred when accessing them. In addition, the "info
1.3211 +vars" command lists uninitialized namespace variables, while the "info
1.3212 +exists" command returns 0 for them. (BL)
1.3213 +
1.3214 +7/29/97 (feature change) Changed the http package to use the ::http
1.3215 +namespace. http_get renamed to http::geturl, http_config renamed to
1.3216 +http::config, http_formatQuery renamed to http::formatQuery.
1.3217 +It now provides the 2.0 version of the package.
1.3218 +The 1.0 version is still available with the old names.
1.3219 +*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b2 but not with Tcl 7.6 ***
1.3220 +
1.3221 +7/29/97 (bug fix, new feature) Tcl_Main now uses Tcl objects internally to
1.3222 +preserve NULLs in commands and command output. Added new API procedure
1.3223 +Tcl_RecordAndEvalObj that resembles Tcl_RecordAndEval but takes an object
1.3224 +containing a command. (BL)
1.3225 +
1.3226 +7/30/97 (bug fix) Tcl freed strings in the environ array even if it
1.3227 +did not allocate them. (SS)
1.3228 +
1.3229 +7/30/97 (bug fix) If a procedure is renamed into a different namespace, it
1.3230 +now executes in the context of that namespace. (BL)
1.3231 +
1.3232 +7/30/97 (bug fix) Prevent renaming of commands into and from namespaces as
1.3233 +part of hiding them. (JL)
1.3234 +
1.3235 +7/31/97 (feature change) Moved the history command from C to tcl.
1.3236 +This uses the ::history namespace. The "words" and "substitute" options
1.3237 +are no longer supported. In addition, the "keep" option without a value
1.3238 +returns the current keep limit. There is a new "clear" option.
1.3239 +The unknown command now supports !! again. (BW)
1.3240 +*** POTENTIAL INCOMPATIBILTY ***
1.3241 +
1.3242 +7/30/97 (bug fix) Made sure that a slave can not fool the master into
1.3243 +hiding the wrong command. Made sure we don't crash in hiding + namespaces
1.3244 +issues. (DL)
1.3245 +
1.3246 +8/4/97 (bug fix) Concat, eval, uplevel, and similar commands were
1.3247 +incorrectly trimming trailing space characters from their arguments
1.3248 +even when the space characters were preceded by a backslash. (JO)
1.3249 +
1.3250 +8/4/97 (bug fix) Removed the hard link between bgerror and tkerror.
1.3251 +Only bgerror is supported in tcl core. Tk will still look for a
1.3252 +tkerror but using regular tcl code for that feature. (DL)
1.3253 +*** POTENTIAL INCOMPATIBILTY with code relying on the hard link ***
1.3254 +
1.3255 +8/6/97 (bug fix) Reduced size required for compiled bytecodes by using a
1.3256 +more compact encoding for the command pc-to-source map. (BL)
1.3257 +
1.3258 +8/6/97 (new feature) Added support for additional compilation and execution
1.3259 +statistics when Tcl is compiled with the TCL_COMPILE_STATS flag. (BL)
1.3260 +
1.3261 +8/7/97 (bug fix) Expressions not in {}s that have a comparison operator as
1.3262 +the topmost operator must be compiled out-of-line (call the expr cmd at
1.3263 +runtime) to properly support expr's two-level substitution semantics. An
1.3264 +example is "set a 2; set b {$a}; puts [expr $b == 2]". (BL)
1.3265 +
1.3266 +8/11/97 (bug fix) The catch command would sometimes crash if a variable name
1.3267 +was given and the bytecode evaluation stack was grown when executing the
1.3268 +argument script. (BL)
1.3269 +
1.3270 +8/12/97 (feature change) Reinstated the variable tcl_precision to control
1.3271 +the number of digits used when floating-point values are converted to
1.3272 +strings, with default of 12 digits. However, had to make tcl_precision
1.3273 +shared among all interpreters (except that safe interpreters can't
1.3274 +modify it). This makes the Tcl 8.0 behavior almost identical to 7.6
1.3275 +except that the default precision is 12 instead of 6. (JO)
1.3276 +*** POTENTIAL INCOMPATIBILITY ***
1.3277 +
1.3278 +----------------- Released 8.0, 8/18/97 -----------------------
1.3279 +
1.3280 +8/19/97 (bug fix) Minimal fix for glob -nocomplain bugs:
1.3281 +"glob -nocomplain unreadableDir/*" was generating an anonymous
1.3282 +error. More in depth fixes will come with 8.1. (DL).
1.3283 +
1.3284 +8/20/97 (bug fix) Removed check for FLT_MIN in binary command so
1.3285 +underflow conditions are handled by the compiler automatic
1.3286 +conversions. (SS)
1.3287 +
1.3288 +8/20/97 (bug fixes) Fixed several compilation-related bugs:
1.3289 + - Array cmd wasn't detecting arrays that, while compiled, do not yet
1.3290 + exist (e.g., are marked undefined since they haven't been assigned
1.3291 + to yet).
1.3292 + - The GetToken procedure in tclCompExpr.c wasn't recognizing properly
1.3293 + whether an integer token was invalid. For example, "0x$" is not
1.3294 + a valid integer.
1.3295 + - Performance bug in TclExecuteByteCode: the size of its stack frame
1.3296 + was reduced by over 20% by moving errorInfo code elsewhere.
1.3297 + - Uninitialized memory read error in tclCompile.c. (BL)
1.3298 +
1.3299 +8/21/97 (bug fix) safe::interpConfigure now behave like Tk widget's
1.3300 +configure : it changes only the options you provide and you can get
1.3301 +the current value of any single option. New ?-nested boolean? and
1.3302 +?-statics boolean? for all safe::interp* commands but we still
1.3303 +accept (upward compatibility) the previously defined non valued
1.3304 +flags ?-noStatics? and ?-nestedLoadOk?. Improved the documentation. (DL).
1.3305 +
1.3306 +8/22/97 (bug fix) Updated PrintDbl.3 to reflect the fact that the
1.3307 +tcl_precision variable is still used and that it is now shared by all
1.3308 +interpreters. (BL)
1.3309 +
1.3310 +8/25/97 (bug fix) Fixed array access bug in IllegalExprOperandType
1.3311 +procedure in tclExecute.c: it was not properly supporting the || and &&
1.3312 +operators. (BL)
1.3313 +
1.3314 +8/27/97 (bug fix) In cases where a channel handler was created with an
1.3315 +empty event mask while data was still buffered in the channel, the
1.3316 +channel code would get stuck spinning on a timer that would starve
1.3317 +idle handlers. This mostly happened in Tk when reading from stdin. (SS)
1.3318 +
1.3319 +9/4/97 (bug fix) Slave interps now inherit the maximum recursion limit
1.3320 +of their parent instead of starting back at the default. {nb: this still
1.3321 +does not prevent stack overflow by multi-interps recursion or aliasing} (DL)
1.3322 +
1.3323 +9/11/97 (bug fix) An uninitialized variable in Tcl_WaitPid caused
1.3324 +pipes to fail to report eof properly under Windows. (SS)
1.3325 +
1.3326 +9/12/97 (bug fix) "exec" was misidentifying some DOS executables as not
1.3327 +executable. (CCS)
1.3328 +
1.3329 +9/14/97 (bug fix) Was using the wrong structure in sizeof operation in
1.3330 +tclUnixChan.c. (JL)
1.3331 +
1.3332 +9/15/97 (bug fix) Fixed notifier to break out of do-one-event loop if
1.3333 +Tcl_WaitForEvent returns 1, so that callers of Tcl_DoOneEvent will get
1.3334 +a chance to check whether the event just handled is significant. This
1.3335 +affected mainly recursive calls to Tcl_VWaitCmd; these did not get a
1.3336 +chance to notice that the variable they were waiting for has been set
1.3337 +and thus they didn't terminate the vwait. (JL, DL, SS)
1.3338 +
1.3339 +9/15/97 (bug fix) Alignment problems in "binary format" would cause a
1.3340 +crash on some platforms when formatting floating point numbers. (SS)
1.3341 +
1.3342 +9/15/97 (bug fix) Fixed bug in Macintosh socket code. Now passes all
1.3343 +tests in socket.test that are not platform specific. (Thanks to Mark
1.3344 +Roseman for the pointer on the fix.) (RJ)
1.3345 +
1.3346 +9/18/97 (bug fix) Fixed bug -dictionary option of lsort that could
1.3347 +cause the compare function to run off the end of an array if the
1.3348 +number only contained 0's. (Thanks to Greg Couch for the report.) (RJ)
1.3349 +
1.3350 +9/18/97 (bug fix) TclFinalizeEnvironment was not cleaning up
1.3351 +properly. (DL, JI)
1.3352 +
1.3353 +9/18/97 (bug fix) Fixed long-standing bug where an "array get" command
1.3354 +did not trigger traces on the array or its elements. (BL)
1.3355 +
1.3356 +9/18/97 (bug fixes) Fixed compilation-related bugs:
1.3357 + - Fixed errorInfo traceback information for toplevel coomands that
1.3358 + contain nested commands.
1.3359 + - In the expr command, && and || now accept boolean operands as well
1.3360 + as numeric ones. (BL)
1.3361 +
1.3362 +9/22/97 (bug fix) Fixed bug that prevented translation modes from being
1.3363 +set independently for input and output on sockets if input was "auto". (JL)
1.3364 +
1.3365 +9/24/97 (bug fix) Tcl_EvalFile(3) and thus source(n) now works fine on
1.3366 +files containing NUL chars. (DL)
1.3367 +
1.3368 +9/26/97 (bug fix) Fixed use of uninitialized memory in the environ array
1.3369 +that later could cause random core dumps. Applies to all platforms. (JL)
1.3370 +
1.3371 +9/26/97 (bug fix) Fixed use of uninitialized memory in socket address data
1.3372 +structure under some circumstances. This could cause random core dumps.
1.3373 +This applies only to Unix. (JL)
1.3374 +
1.3375 +9/26/97 (bug fix) Opening files on PC-NFS volumes would cause a hang
1.3376 +until the system timed after the file was closed. (SS)
1.3377 +
1.3378 +10/6/97 (bug fix) The join(n) command, though objectified, was loosing
1.3379 +NULs in the joinString and in list elements after the 2nd one.
1.3380 +Now you can "join $list \0" for instance. (DL)
1.3381 +
1.3382 +10/9/97 (bug fix) Under windows, if env(TMP) or env(TEMP) referred to a
1.3383 +non-existent directory, exec would fail when trying to create its temporary
1.3384 +files. (CCS)
1.3385 +
1.3386 +10/9/97 (bug fix) Under mac and windows, "info hostname" would crash if
1.3387 +sockets were installed but the hostname could not be determined anyhow.
1.3388 +Tcl_GetHostName() was returning NULL when it should have been returning
1.3389 +an empty string. (CCS)
1.3390 +
1.3391 +10/10/97 (bug fix) "file attribute /" returned error on windows. (CCS)
1.3392 +
1.3393 +10/10/97 (bug fix) Fixed the auto_load procedure to handle procedures
1.3394 +defined in namespaces better. Also fixed pgk_mkIndex so it sees procedures
1.3395 +defined in nested namespaces. Index entries are still only made for
1.3396 +exported procedures. (BW)
1.3397 +
1.3398 +10/13/97 (bug fix) On unix, for files with unknown group or owner
1.3399 +attributes, querying the "file attributes" would return an error rather than
1.3400 +returning the group's or owner's id number, although tha command accepts
1.3401 +numbers when setting the file's group or owner. (CCS)
1.3402 +
1.3403 +10/22/97 (bug fix) "fcopy" did not eval the callback script at the
1.3404 +global scope. (SS)
1.3405 +
1.3406 +10/22/97 (bug fix) Fixed the signature of the CopyDone callback used in
1.3407 +the http package(s) so they can handle error cases properly. (BW)
1.3408 +
1.3409 +10/28/97 (bug fixes) Fixed a problem where lappend would free the Tcl object
1.3410 +in a variable if a Tcl_ObjSetVar2 failed because of an error calling a trace
1.3411 +on the variable. (BL)
1.3412 +
1.3413 +10/28/97 (bug fix) Changed binary scan to properly handle sign
1.3414 +extension of integers on 64-bit or larger machines. (SS)
1.3415 +
1.3416 +11/3/97 (bug fixes) Fixed several bugs:
1.3417 + - expressions such as "expr ($x)" must be compiled out-of-line
1.3418 + (call the expr command procedure at runtime) to ensure the correct
1.3419 + behavior when "$x" is an expression such as "5+10".
1.3420 + - "array set a {}" now creates a new array var with an empty array
1.3421 + value if the var didn't already exist.
1.3422 + - "lreplace $foo end end" no longer returns an error (just an empty
1.3423 + list) if foo is empty.
1.3424 + - upvar will no longer create a variable in a namespace that refers
1.3425 + to a variable in a procedure.
1.3426 + - deleting a command trace within a command trace callback would
1.3427 + make the code that calls traces to reference freed memory.
1.3428 + - significantly sped up "string first" and "string last" (fix from
1.3429 + darrel@gemstone.com).
1.3430 + - seg fault in Tcl_NewStringObj() when a NULL is passed as the byte
1.3431 + pointer argument and Tcl is compiled with -DTCL_MEM_DEBUG.
1.3432 + - documentation and error msg fixes. (BL)
1.3433 +
1.3434 +11/3/97 (bug fix) Fixed a number of I/O bugs related to word sizes on
1.3435 +64-bit machines. (SS)
1.3436 +
1.3437 +11/6/97 (bug fix) The exit code of the first process created by Tcl
1.3438 +on Windows was not properly reported due to an initialization
1.3439 +problem. (SS)
1.3440 +
1.3441 +----------------- Released 8.0p1, 11/7/97 -----------------------
1.3442 +
1.3443 +11/19/97 (bug fix) Fixed bug in linsert where it sometimes accidently
1.3444 +cleared out a shared argument list object. (BL).
1.3445 +
1.3446 +11/19/97 (bug fix) Autoloading in namespaces was not working properly.
1.3447 +auto_mkindex is still not really namespace aware but most common
1.3448 +cases should now be handled properly (see init.test). (BW, DL)
1.3449 +
1.3450 +11/20/97 (enhancement) Made the changes required by the new Apple
1.3451 +Universal Headers V.3.0, so that Tcl will compile with CW Pro 2.
1.3452 +
1.3453 +11/24/97 (bug fix) Fixed tests in clock test suite that needed the
1.3454 +-gmt flag set. Thanks to Jan Nijtmans for reporting the problem. (RJ)
1.3455 +
1.3456 +----------------- Released 8.0p2, 11/25/97 -----------------------
1.3457 +
1.3458 +12/3/97 (bug fix/optimization) Removed uneeded and potentially dangerous
1.3459 +instances of double evaluations if "if" and "expr" statements from
1.3460 +the library files. It is recommended that unless you need a double
1.3461 +evaluation you always use "expr {...}" instead of "expr ..." and
1.3462 +"if {...} ..." instead of "if ... ...". It will also be faster
1.3463 +thanks to the byte compiler. (DL)
1.3464 +
1.3465 +---- Shipped as part of the plugin2.0b5 as 8.0p2Plugin1, Dec 8th 97 ----
1.3466 +
1.3467 +12/8/97 (bug fix) Need to protect the newly accepted channel in an
1.3468 +accept callback on a socket, otherwise the callback may close it and
1.3469 +cause an error, which would cause the C code to attempt to close the
1.3470 +now deleted channel. Bumping the refcount assures that the channel sticks
1.3471 +around to be really closed in this case. (JL)
1.3472 +
1.3473 +12/8/97 (bug fix) Need to protect the channel in a fileevent so that it
1.3474 +is not deleted before the fileevent handler returns. (CS, JL)
1.3475 +
1.3476 +12/18/97 (bug fix) In the opt argument parsing package: if the description
1.3477 +had only flags, the "too many arguments" case was not detected. The default
1.3478 +value was not used for the special "args" ending argument. (DL)
1.3479 +
1.3480 +1/15/98 (improvement) Moved common part of initScript in common file.
1.3481 +Moved windows specific initialization to init.tcl so you can initialize
1.3482 +Tcl in windows without having to call Tcl_Init which is now only
1.3483 +searching for init.tcl {back ported from 8.1}. (DL)
1.3484 +
1.3485 +---- Shipped as part of the plugin as 8.0p2Plugin2, Jan 15th 98 ----
1.3486 +
1.3487 +5/27/98 (bug fix) Windows socket driver did not notice new data arriving
1.3488 +on nonblocking sockets until the event loop was entered. (SS)
1.3489 +
1.3490 +5/27/98 (bug fix) Windows socket driver used FIONREAD, which is not
1.3491 +supported correctly by WinSock. (SS)
1.3492 +
1.3493 +6/9/98 (bug fix) Generic channel code failed to report readable file
1.3494 +events on buffered data that was left behind by a gets or read that
1.3495 +did not consume all available data. (SS)
1.3496 +
1.3497 +6/18/98 (bug fix) Compilation of loop expressions was too aggressive
1.3498 +and incorrectly inlined non-literal expressions. (SS)
1.3499 +
1.3500 +6/18/98 (bug fix) "info var" and "info locals" incorrectly reported
1.3501 +the existence of compiler temporary variables. (SS)
1.3502 +
1.3503 +6/18/98 (bug fix) Dictionary sorting used signed character
1.3504 +comparisons. (SS)
1.3505 +
1.3506 +6/18/98 (bug fix) Compile procs corrupted the exception stack in some
1.3507 +cases. (SS)
1.3508 +
1.3509 +6/18/98 (bug fix) Array set had erratic behavior when initializing a
1.3510 +variable from an empty value list. (SS)
1.3511 +
1.3512 +6/18/98 (bug fix) The Windows registry package had a bad bounds check
1.3513 +that could lead to a crash. (SS)
1.3514 +
1.3515 +6/18/98 (bug fix) The foreach compile proc did not correctly handle
1.3516 +non-local variable references. (SS)
1.3517 +
1.3518 +6/25/98 (new features) Added name resolution hooks to support [incr Tcl].
1.3519 +There are new internal Tcl_*Resolver* APIs to add, query and remove the hooks.
1.3520 +With this changes it should be possible to dynamically load [incr Tcl]
1.3521 +as an extension. (MM)
1.3522 +
1.3523 +7/1/97 (bug fix) The commands "info args, body, default, procs" did
1.3524 +not correctly handle imported procedures. (RJ)
1.3525 +
1.3526 +7/6/98 (improvement) pkg_mkIndex now implements the "package require"
1.3527 +command. This makes it possible to create index files for packages
1.3528 +that require another package and then execute code from that package in
1.3529 +their file. Previously, this would throw an error because the required
1.3530 +package had not been loaded. The -nopkgrequied flag is provided to
1.3531 +revert back to the old functionality. (EMS)
1.3532 +
1.3533 +7/6/98 (improvement) back-ported the -direct flag from 8.1 into
1.3534 +pkg_mkIndex. This results in pkgIndex.tcl files that contain direct
1.3535 +source or load commands instead of tclPkgSetup commands. (EMS)
1.3536 +
1.3537 +7/6/98 (improvement) made changes to the AuxData items structures to support
1.3538 +storage of compiled scripts on disk. Also some related minor changes in
1.3539 +the compilation and execution engine. (EMS)
1.3540 +
1.3541 +6/4/98 (enhancement) Added new internal routines to support inserting
1.3542 +and deleting from the stat, access, and open-file-channel mechanisms.
1.3543 +TclAccessInsertProc, TclStatInsertProc, & TclOpenFileChannelInsertProc
1.3544 +insert pointers to such routines; TclAccessDeleteProc, TclStatDeleteProc,
1.3545 +& TclOpenFileChannelDeleteProc delete pointers to such routines. See
1.3546 +the file generic/tclIOUtils.c for more details. (SKS)
1.3547 +
1.3548 +7/1/98 (enhancement) Added a new internal C variable
1.3549 +tclPreInitScript. This is a pointer to a string that may hold an
1.3550 +initialization script; If this pointer is non-NULL it is evaluated in
1.3551 +Tcl_Init() prior to the built-in initialization script defined in the
1.3552 +file generic/tclInitScript.h. (SKS)
1.3553 +
1.3554 +7/6/98 (bug fix) Removed dead code in PlatformInitExitHandler so that
1.3555 +the TCL_LIBRARY value can be safely patched in binaries. (BW)
1.3556 +
1.3557 +7/24/98 (enhancement) Incorporated a new version of auto_mkindex that
1.3558 +can support the [incr Tcl] class structures. This version will index
1.3559 +all procedures in a source file, not just those where "proc" starts
1.3560 +at the beginning of the line. If you want the old behavior, use the
1.3561 +auto_mkindex_old procedure. (MM)
1.3562 +
1.3563 +7/24/98 (feature change) Changed the Windows registry key to be
1.3564 +HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, and to store the path
1.3565 +in the default value instead of "Root". Also, this key can be
1.3566 +specified at compile time in case Tcl is being used in a different
1.3567 +context where it needs an alternate library path from the standard Tcl
1.3568 +installation. (SS)
1.3569 +
1.3570 +7/24/98 (feature change) Changed the search order for init.tcl. The
1.3571 +tcl_library variable can now be set before calling Tcl_Init to avoid
1.3572 +doing any searches. If it isn't set, then Tcl checks
1.3573 +env(TCL_LIBRARY), the static value set at compile time, an install
1.3574 +directory relative to the executable, a source directory relative to
1.3575 +the executable, and a tcl directory relative to the source heirarchy
1.3576 +containing the executable. See the comment at the top of
1.3577 +generic/tclInitScript.h for more details. (SS)
1.3578 +
1.3579 +7/27/98 (config change) Changed the use of the DBGX flag in configure.in
1.3580 +and the makefile to be TCL_DBGX. Users of tclConfig.sh may need to pass
1.3581 +this through their configure files with AC_SUBST. (BW)
1.3582 +
1.3583 +729/98 (bug fix) Changed [info body] to return a copy of the body of a
1.3584 +compiled procedure instead of the body itself, to avoid invalidation
1.3585 +of the internal rep and loss of the byte-codes. (EMS)
1.3586 +
1.3587 +8/5/98 (bug fix) The platform init code could walk off the end of a
1.3588 +buffer when reading the PkgPath registry value on Windows. (SS)
1.3589 +
1.3590 +8/5/98 (Windows makefile change) Introduced a set of macros to deal with
1.3591 +exporting symbols when compiling DLLS on Windows. See win/README for
1.3592 +details. (EMS)
1.3593 +
1.3594 +8/5/98 (addendum) Added a second Windows registry key under
1.3595 +HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, named "pkgPath".
1.3596 +This is a multi-string value used to initialize the tcl_pkgPath
1.3597 +variable. This is required if extension DLLs are in architecture specific
1.3598 +subdirectories. (SS)
1.3599 +
1.3600 +8/6/98 (new feature) Added tcl_findLibrary to init.tcl for use by
1.3601 +extensions, including Tk. This searches in a canonical way for
1.3602 +an extensions library directory and initialization file. (BW)
1.3603 +
1.3604 +8/10/98 (bug fix) Imported commands used to get lost if the target
1.3605 +of the import was redefined. Tcl_CreateCommand and Tcl_CreateObjCommand
1.3606 +were updated to restore import links. (Note that if you rename a command,
1.3607 +the import links move to the new name, and if you delete a command then
1.3608 +the import links get lost. These semantics have not changed.) (MC)
1.3609 +
1.3610 +-------- Released 8.0.3 to the Tcl Consortium CD-ROM project, 8/10/98 ------
1.3611 +
1.3612 +9/3/98 (bug fix) Tcl_Realloc was failing under Windows because the
1.3613 +GlobalReAlloc API was not correctly re-allocating blocks that were
1.3614 +32k+. The fix was to use newer Win32 APIs (HeapAlloc, HeapFree, and
1.3615 +HeapReAlloc.) (BS)
1.3616 +
1.3617 +10/5/98 (bug fix) Fixed bug in pkg_mkIndex that caused some files that do
1.3618 +a "package require" of packages in the Tcl libraries to give a warning like
1.3619 + warning: "xx.tcl" provides more than one package ({xx 2.0} {yy 0.3})
1.3620 +and generate a broken pkgIndex.tcl file. (EMS)
1.3621 +
1.3622 +10/5/98 (bug fix) Pkg_mkIndex was not doing a case-insensitive comparison
1.3623 +of extensions to determine whether to load or source a file. Thus, under
1.3624 +Windows, MYDLLNAME.DLL was sourced, and mydllname.dll loaded. (EMS)
1.3625 +
1.3626 +10/5/98 (new feature) Created a new Tcl_Obj type, "procbody". This object's
1.3627 +internal representation holds a pointer to a Proc structure. Extended
1.3628 +TclCreateProc to take both strings and "procbody". (EMS)
1.3629 +
1.3630 +10/13/98 (bug fix) The "info complete" command can now handle strings
1.3631 +with NULLs embedded. Thanks to colin@field.medicine.adelaide.edu.au
1.3632 +for providing this fix. (RJ)
1.3633 +
1.3634 +10/13/98 (bug fix) The "lsort -dictionary" command did not properly
1.3635 +handle some numbers starting with 0. Thanks to Richard Hipp
1.3636 +<drh@acm.org> for submitting the fix to Scriptics. (RJ)
1.3637 +
1.3638 +10/13/98 (bug fix) The function Tcl_SetListObj was creating an invalid
1.3639 +Tcl_Obj if the list had zero elements (despite what the comments said
1.3640 +it would do). Thanks to Sebastian Wangnick for reporting the
1.3641 +problem. (RJ)
1.3642 +
1.3643 +10/20/98 (new feature) Added tcl_platform(debug) element to the
1.3644 +tcl_platform array on Windows platform. The existence of the debug
1.3645 +element of the tcl_platform array indicates that the particular Tcl
1.3646 +shell has been compiled with debug information. Using
1.3647 +"info exists tcl_platform(debug)" a Tcl script can direct the
1.3648 +interpreter to load debug versions of DLLs with the load
1.3649 +command. (SKS)
1.3650 +
1.3651 +10/20/98 (feature change) The Makefile and configure scripts have been
1.3652 +changed for IRIX to build n32 binaries instead of the old 32 abi
1.3653 +format. If you have extensions built with the o32 abi's you will need
1.3654 +to update them to n32 for them to work with Tcl. (RJ)
1.3655 +*** POTENTIAL INCOMPATIBILITY ***
1.3656 +
1.3657 +10/23/98 (bug fix) tcl_findLibrary had a stray ] in one of the
1.3658 +pathnames it searched for the initialization script. tclInitScript.h
1.3659 +was incorrectly adding the parent of tcl_library to tcl_pkgPath. This
1.3660 +logic was moved into init.tcl, and the initialization of auto_path was
1.3661 +documented. Thanks to Donald Porter and Tom Silva for related
1.3662 +patches. (BW)
1.3663 +
1.3664 +10/29/98 (bug fix) Fixed Tcl_NotifyChannel to use Tcl_Preserve instead
1.3665 +of Tcl_RegisterChannel so that 1) unregistered channels do not get
1.3666 +closed after their first fileevent, and 2) errors that occur during
1.3667 +close in a fileevent script are actually reflected by the close
1.3668 +command. (BW)
1.3669 +
1.3670 +10/30/98 (bug fix) Overhaul of pkg_mkIndex to deal with transitive
1.3671 +package requires and packages split among scripts and binary files.
1.3672 +Also fixed ommision of global for errorInfo in tcl_findLibrary. (BW)
1.3673 +
1.3674 +11/08/98 (bug fix) Fixed the resource command to always detect
1.3675 +the case where a file is opened a second time with the same
1.3676 +permissions. IM claims that this will always cause the same
1.3677 +FileRef to be returned, but in MacOS 8.1+, this is no longer the case,
1.3678 +so we have to test for this explicitly. (JI)
1.3679 +
1.3680 +11/10/98 (feature change) When compiling with Metrowerk's MSL, use the
1.3681 +exit function from MSL rather than ExitToShell. This allows MSL to
1.3682 +clean up its temporary files. Thanks to Vince Darley for this
1.3683 +improvement. (JI)
1.3684 +
1.3685 +----------------- Released 8.0.4, 11/19/98 -------------------------
1.3686 +
1.3687 +11/20/98 (bug fix) Handle possible NULL return in TclGetStdFiles. (RJ)
1.3688 +
1.3689 +11/20/98 (bug fix) The dltests would not build on SGI. They reported
1.3690 +that you could not mix n32 with 032 binaries. The configure script
1.3691 +has been modified to get the EXTRA_CFLAGS from the tcl configure
1.3692 +script. [Bug id: 840] (RJ)
1.3693 +
1.3694 +12/3/98 (bug fix) Windows NT creates sockets so they are inheritable
1.3695 +by default. Fixed socket code so it turns off this bit right after
1.3696 +creation so sockets aren't kept open by exec'ed processes. [Bug: 892]
1.3697 +Thanks to Kevin Kenny for this fix. (SS)
1.3698 +
1.3699 +1/11/98 (bug fix) On HP, "info sharedlibextension" was returning
1.3700 +empty string on static apps. It now always returns ".sl". (RJ)
1.3701 +
1.3702 +1/28/99 (configure change) Now support -pipe option on gcc. (RJ)
1.3703 +
1.3704 +2/2/99 (bug fix) Fixed initialization problem on Windows where no
1.3705 +searching for init.tcl would be performed if the registry keys were
1.3706 +missing. (stanton)
1.3707 +
1.3708 +2/2/99 (bug fix) Added support for HKEY_PERFORMANCE_DATA and
1.3709 +HKEY_DYN_DATA keys in the "registry" command. (stanton)
1.3710 +
1.3711 +2/2/99 (bug fix) ENOTSUP and EOPNOTSUPP clashed on some Linux
1.3712 +variants. (stanton)
1.3713 +
1.3714 +2/2/99 (enhancement) The "open" command has been changed to use the
1.3715 +object interfaces. (stanton)
1.3716 +
1.3717 +2/2/99 (bug fix) In some cases Tcl would crash due to an overflow of
1.3718 +the exception stack resulting from a missing byte code in some
1.3719 +expressions. (stanton)
1.3720 +
1.3721 +2/2/99 (bug fix) Changed configure so Linux and IRIX shared libraries
1.3722 +are linked with the system libraries. (stanton)
1.3723 +
1.3724 +2/2/99 (bug fix) Added support for BSDI 4.x (BSD/OS-4*) to the
1.3725 +configure script. (stanton)
1.3726 +
1.3727 +2/2/99 (bug fix) Fixed bug where upvar could resurrect a namespace
1.3728 +variable after the namespace had been deleted. (stanton)
1.3729 +
1.3730 +2/2/99 (bug fix) In some cases when creating variables, the
1.3731 +interpreter result was being modified even if the TCL_LEAVE_ERR_MSG
1.3732 +flag was set. (stanton)
1.3733 +
1.3734 +2/2/99 (bug fix & new feature) Changed the socket drivers to properly
1.3735 +handle failures during an async socket connection. Added a new
1.3736 +fconfigure option "-error" to retrieve the failure message. See the
1.3737 +socket.n manual entry for details. (stanton)
1.3738 +
1.3739 +2/2/99 (bug fix) Deleting a renamed interp alias could result in a
1.3740 +panic. (stanton)
1.3741 +
1.3742 +2/2/99 (feature change/bug fix) Changed the behavior of "file
1.3743 +extension" so that it splits at the last period. Now the extension of
1.3744 +a file like "foo..o" is ".o" instead of "..o" as in previous versions.

1.3752 +6/18/97 (new feature) Tcl now supports international character sets:
1.3753 + - All C APIs now accept UTF-8 strings instead of iso8859-1 strings,
1.3754 + wherever you see "char *", unless explicitly noted otherwise.
1.3755 + - All Tcl strings represented in UTF-8, which is a convenient
1.3756 + multi-byte encoding of Unicode. Variable names, procedure names,
1.3757 + and all other values in Tcl may include arbitrary Unicode characters.
1.3758 + For example, the Tcl command "string length" returns how many
1.3759 + Unicode characters are in the argument string.
1.3760 + - For Java compatibility, embedded null bytes in C strings are
1.3761 + represented as \xC080 in UTF-8 strings, but the null byte at the end
1.3762 + of a UTF-8 string remains \0. Thus Tcl strings once again do not
1.3763 + contain null bytes, except for termination bytes.
1.3764 + - For Java compatibility, "\uXXXX" is used in Tcl to enter a Unicode
1.3765 + character. "\u0000" through "\uffff" are acceptable Unicode
1.3766 + characters.
1.3767 + - "\xXX" is used to enter a small Unicode character (between 0 and 255)
1.3768 + in Tcl.
1.3769 + - Tcl automatically translates between UTF-8 and the normal encoding for
1.3770 + the platform during interactions with the system.
1.3771 + - The fconfigure command now supports a -encoding option for specifying
1.3772 + the encoding of an open file or socket. Tcl will automatically
1.3773 + translate between the specified encoding and UTF-8 during I/O.
1.3774 + See the directory library/encoding to find out what encodings are
1.3775 + supported (eventually there will be an "encoding" command that
1.3776 + makes this information more accessible).
1.3777 + - There are several new C APIs that support UTF-8 and various encodings.
1.3778 + See Utf.3 for procedures that translate between Unicode and UTF-8
1.3779 + and manipulate UTF-8 strings. See Encoding.3 for procedures that
1.3780 + create new encodings and translate between encodings. See
1.3781 + ToUpper.3 for procedures that perform case conversions on UTF-8
1.3782 + strings.
1.3783 +
1.3784 +9/18/97 (enhancement) Literal objects are now shared by the ByteCode
1.3785 +structures created when compiled different scripts. This saves up to 45%
1.3786 +of the total memory needed for all literals. (BL)
1.3787 +
1.3788 +9/24/97 (bug fixes) Fixed Tcl_ParseCommand parsing of backslash-newline
1.3789 +sequences at start of command words. Suppressed Tcl_EvalDirect error logging
1.3790 +if non-TCL_OK result wasn't an error. (BL)
1.3791 +
1.3792 +10/17/97 (feature enhancement) "~username" now refers to the users' home
1.3793 +directory on Windows (previously always returned failure). (CCS)
1.3794 +
1.3795 +10/20/97 (implementation change) The Tcl parser has been completely rewritten
1.3796 +to make it more modular. It can now be used to parse a script without actually
1.3797 +executing it. The APIs for the new parser are not correctly exported, but
1.3798 +they will eventually be exported and augmented with Tcl commands so that
1.3799 +Tcl scripts can parse other Tcl scripts. (JO)
1.3800 +
1.3801 +10/21/97 (API change) Added "flags" argument to Tcl_EvalObj, removed
1.3802 +Tcl_GlobalEvalObj procedure. Added new procedures Tcl_Eval2 and
1.3803 +Tcl_EvalObjv. (JO)
1.3804 +*** POTENTIAL INCOMPATIBILITY ***
1.3805 +
1.3806 +10/22/97 (API change) Renamed Tcl_ObjSetVar2 and Tcl_ObjGetVar2 to
1.3807 +Tcl_SetObjVar2 and Tcl_GetObjVar2 (for consistency with other C APIs)
1.3808 +and changed the name arguments to be strings instead of objects. (JO)
1.3809 +*** POTENTIAL INCOMPATIBILITY ***
1.3810 +
1.3811 +10/27/97 (enhancement) Bytecode compiler rewritten to use the new Tcl
1.3812 +parser. (BL)
1.3813 +
1.3814 +11/3/97 (New routines) Added Tcl_AppendObjToObj, which appends the
1.3815 +string rep of one Tcl_Obj to another. Added Tcl_GetIndexFromObjStruct,
1.3816 +which is similar to Tcl_GetIndexFromObj, except that you can give an
1.3817 +offset between strings. This allows Tcl_GetIndexFromObjStruct to be
1.3818 +called with a table of records which have strings in them. (SRP)
1.3819 +
1.3820 +12/4/97 (enhancement) New Tcl expression parser added. Added new procedure
1.3821 +Tcl_ParseExpr and new token types TCL_TOKEN_SUB_EXPR and
1.3822 +TCL_TOKEN_OPERATOR. Expression compiler is reimplemented to use this
1.3823 +parser. (BL)
1.3824 +
1.3825 +12/9/97 (bug fix) Tcl_EvalObj() increments/decrements the refcount of the
1.3826 +script object to prevent the object from deleting itself while in the
1.3827 +middle of being evaluated. (CCS)
1.3828 +
1.3829 +12/9/97 (bug fix) Memory leak in Tcl_GetsObjCmd(). (CCS)
1.3830 +
1.3831 +12/11/97 (bug fix) Environment array leaked memory when compiled with
1.3832 +Visual C++. (SS)
1.3833 +
1.3834 +12/11/97 (bug fix) File events and non-blocking I/O did not work on
1.3835 +pipes under Windows. Changed to use threads to achieve non-blocking
1.3836 +behavior. (SS)
1.3837 +
1.3838 +12/18/97 (bug fixes) Fixed segfault in "namespace import"; importing a
1.3839 +procedure that causes a cycle now returns an error. Modified "info procs",
1.3840 +"info args", "info body", and "info default" to return information about
1.3841 +imported procedures as well as procedures defined in a namespace. (BL)
1.3842 +
1.3843 +12/19/97 (enhancement) Added new Tcl_GetString() procedure that can be used
1.3844 +in place of Tcl_GetStringFromObj() if the string representation's length
1.3845 +isn't needed. (BL)
1.3846 +
1.3847 +12/18/97 (bug fix) In the opt argument parsing package: if the description
1.3848 +had only flags, the "too many arguments" case was not detected. The default
1.3849 +value was not used for the special "args" ending argument. (DL)
1.3850 +
1.3851 +1/7/98 (clean up) Moved everything not absolutly necessary out of init.tcl
1.3852 +procs now in auto.tcl and package.tcl can be autoloaded if needed. (DL)
1.3853 +
1.3854 +1/7/98 (enhancement) tcltest made at install time will search for it's
1.3855 +init.tcl where it is, even when using virtual path compilation. (DL)
1.3856 +
1.3857 +1/8/98 (os bug workaround) when needed, using a replacement for memcmp so
1.3858 +string compare "char with high bit set" "char w/o high bit set" returns
1.3859 +the expected value on all platforms. (DL)
1.3860 +
1.3861 +1/8/98 (unix portability/configure) building from .../unix/targetName/
1.3862 +subdirectories and simply using "../configure" should now work fine. (DL)
1.3863 +
1.3864 +1/14/98 (enhancement) Added new regular expression package that
1.3865 +supports AREs, EREs, and BREs. The new package includes new escape
1.3866 +characters, meta-syntax, and character classes inside brackets.
1.3867 +Regexps involving backslashes may behave differently. (MH)
1.3868 +*** POTENTIAL INCOMPATIBILITY ***
1.3869 +
1.3870 +1/16/98 (os workaround) Under windows, "file volume" was causing chatter
1.3871 +and/or several seconds of hanging when querying empty floppy drives.
1.3872 +Changed implementation to call an empirically-derived function that doesn't
1.3873 +cause this. (CCS)
1.3874 +
1.3875 +1/16/98 (enhancement) Converted regular expressions to a Tcl_Obj type so
1.3876 +their compiled form gets cached automatically. Reduced NSUBEXP from 100
1.3877 +to 20. (BW)
1.3878 +
1.3879 +1/16/98 (documentation) Change unclear documentation and comments for
1.3880 +functions like Tcl_TranslateFileName() and Tcl_ExternalToUtfDString(). Now
1.3881 +it explicitly says they take an uninitialized or free DString. A DString
1.3882 +that is "empty" or "not holding anything" could have been interpreted as one
1.3883 +currently with a zero length, but with a large dynamically allocated buffer.
1.3884 +(CCS)
1.3885 +
1.3886 +----------------- Released 8.1a1, 1/22/98 -----------------------
1.3887 +
1.3888 +1/28/98 (new feature) Added a "-direct" optional flag to pkg_mkIndex
1.3889 +to generate direct loading package indexes (such those you need
1.3890 +if you use namespaces and plan on using namespace import just after
1.3891 +package require). pkg_mkIndex still has limitations regarding
1.3892 +package dependencies but errors are now ignored and with -direct, correct
1.3893 +package indexes can be generated even if there are dependencies as long
1.3894 +as the "package provide" are done early enough in the files. (DL)
1.3895 +
1.3896 +1/28/98 (enhancement) Performance tuning of regexp and regsub. (CCS)
1.3897 +
1.3898 +1/28/98 (bug fix) regexp and regsub with "-indices" returned the byte-offsets
1.3899 +of the characters in the UTF-8 representation, not the character offsets
1.3900 +themselves. (CCS)
1.3901 +
1.3902 +1/28/98 (bug fix) "clock format 0 -format %Z -gmt 1" would return the local
1.3903 +timezone string instead of "GMT" on Solaris and Windows.
1.3904 +
1.3905 +1/28/98 (bug fix) Restore tty settings when closing serial device on Unix.
1.3906 +This is good behavior when closing real serial devices, essential when
1.3907 +closing the pseudo-device /dev/tty because the user's terminal settings
1.3908 +would be left useless, in raw mode, when tcl quit. (CCS)
1.3909 +
1.3910 +1/28/98 (bug fix) Tcl_OpenCommandChannel() was modifying the contents of the
1.3911 +argv array passed to it, causing problems for any caller that wanted to
1.3912 +continue to use the argv array after calling Tcl_OpenCommandChannel(). (CCS)
1.3913 +
1.3914 +2/1/98 (bug fix) More bugs with %Z in format string argument to strftime():
1.3915 +1. Borland always returned empty string.
1.3916 +2. MSVC always returned the timezone string for the current time, not the
1.3917 + timezone string for the specified time.
1.3918 +3. With MSVC, "clock format 0 -format %Z -gmt 1" would return "GMT" the first
1.3919 + time it was called, but would return the current timezone string on all
1.3920 + subsequent calls. (CCS)
1.3921 +
1.3922 +2/1/98 (bug fix) "file stat" was broken on Windows.
1.3923 +1. "file stat" of a root directory (local or network) or a relative path that
1.3924 + resolved to a root directory (c:. when in pwd was c:/) was returning error.
1.3925 +2. "file stat" on a regular file (S_IFREG), the st_mode was sign extended to
1.3926 + a negative int if the platform-dependant type "mode_t" was declared as a
1.3927 + short instead of an unsigned short.
1.3928 +3. "file stat" of a network directory, the st_dev was incorrectly reported
1.3929 + as the id of the last accessed local drive rather than the id of the
1.3930 + network drive. (CCS)
1.3931 +
1.3932 +2/1/98 (bug fix) "file attributes" of a relative path that resolved to a
1.3933 +root directory was returning error. (CCS)
1.3934 +
1.3935 +2/1/98 (bug fix) Change error message when "file attribute" could not
1.3936 +determine the attributes for a file. Previously it would return different
1.3937 +error messages on Unix vs. Windows vs. Mac. (CCS)
1.3938 +
1.3939 +2/4/98 (bug fixes) Fixed several instances of bugs where the parser/compiler
1.3940 +would reach outside the range of allocated memory. Improved the array
1.3941 +lookup algorithm in set compilation. (DL)
1.3942 +
1.3943 +2/5/98 (change) The TCL_PARSE_PART1 flag for Set/Get(Obj)Var2 C APIs is now
1.3944 +deprecated and ignored. The part1 is always parsed when the part2 argument
1.3945 +is NULL. This is to avoid a pattern of errors for extension writers converting
1.3946 +from string based Tcl_SetVar() to new Tcl_SetObjVar2() and who could easily
1.3947 +forget to provide the flag and thus get code working for normal variables
1.3948 +but not for array elements. The performance hit is minimal. A side effect
1.3949 +of that change is that is is no longer possible to create scalar variables
1.3950 +that can't be accessed by tcl scripts because of their invalid name
1.3951 +(ending with parenthesis). Likewise it is also parsed and checked to
1.3952 +ensure that you don't create array elements of array whose name is a valid
1.3953 +array element because they would not be accessible from scripts anyway.
1.3954 +Note: There is still duplicate array elements parsing code. (DL)
1.3955 +*** POTENTIAL INCOMPATIBILITY ***
1.3956 +
1.3957 +2/11/98 (bug fix) Sharing objects between interps, such as by "interp
1.3958 +eval" or "send" could cause a crash later when dereferencing an interp
1.3959 +that had been deleted, given code such as:
1.3960 + set a {set x y}
1.3961 + interp create foo
1.3962 + interp eval foo $a
1.3963 + interp delete foo
1.3964 + unset a
1.3965 +Interp "foo" was gone, but "a" had a internal rep consisting of bytecodes
1.3966 +containing a dangling pointer to "foo". Unsetting "a" would attempt to
1.3967 +return resources back to "foo", causing a crash as random memory was
1.3968 +accessed. The lesson is that that if an object's internal rep depends on
1.3969 +an interp (or any other data structure) it must preserve that data in
1.3970 +some fashion. (CCS)
1.3971 +
1.3972 +2/11/98 (enhancement) The "interp" command was returning inconsistent error
1.3973 +messages when the specified slave interp could not be found. (CCS)
1.3974 +
1.3975 +2/11/98 (bug fix) Result codes like TCL_BREAK and TCL_CONTINUE were not
1.3976 +propagating through the master/slave interp boundaries, such as "interp
1.3977 +eval" and "interp alias". TCL_OK, TCL_ERROR, and non-standard codes like
1.3978 +teh integer 57 work. There is still a question as to whether TCL_RETURN
1.3979 +can/should propagate. (CCS)
1.3980 +
1.3981 +2/11/98 (bug fix) TclCompileScript() was derefering memory 1 byte before
1.3982 +start of the string to compile, looking for ']'. (CCS,DL)
1.3983 +
1.3984 +2/11/98 (bug fix) Tcl_Eval2() was derefering memory 1 byte before start
1.3985 +of the string to eval, looking for ']'. (CCS,DL)
1.3986 +
1.3987 +2/11/98 (bug fix) Compiling "set a(b" was running off end of string. (CCS,DL)
1.3988 +
1.3989 +2/11/98 (bug fix) Windows initialization code was dereferencing
1.3990 +uninitialized memory if TCL_LIBRARY environment didn't exist. (CCS)
1.3991 +
1.3992 +2/11/98 (bug fix) Windows "registry" command was dereferencing
1.3993 +uninitialized memory when constructing the $errorCode for a failed
1.3994 +registry call. (CCS)
1.3995 +
1.3996 +2/11/98 (enhancement) Eliminate the TCL_USE_TIMEZONE_VAR definition from
1.3997 +configure.in, because it was the same information as the already existing
1.3998 +HAVE_TM_ZONE definition. The lack of HAVE_TM_ZONE is used to work around a
1.3999 +Solaris and Windows bug where "clock format [clock sec] -format %Z -gmt 1"
1.4000 +produces the local timezone string instead of "GMT". (CCS)
1.4001 +
1.4002 +2/11/98 (bug fix) Memleaks and dereferencing of uninitialized memory in
1.4003 +regexp if an error occurred while compiling a regular expression. (CCS).
1.4004 +
1.4005 +2/18/98 (new feature) Added mutexes and thread local storage in order
1.4006 +to make Tcl thread safe. For testing purposes, there is a testthread
1.4007 +command that creates a new thread and an interpreter inside it. See
1.4008 +thread.test for examples, but this script-level interface is not fixed.
1.4009 +Each thread has its own notifier instance to manage its own events,
1.4010 +and threads can post messages to each other's message queue.
1.4011 +This uses pthreads on UNIX, and native thread support on other platforms.
1.4012 +You enable this by configuring with --enable-threads. Note that at
1.4013 +this time *Tk* is still not thread safe. Special thanks to
1.4014 +Richard Hipp: his earlier implementation inspired this work. (BW, SS, JI)
1.4015 +
1.4016 +2/18/98 (hidden feature change) The way the env() array is shared among
1.4017 +interpreters changed. Updates to env used to trigger write traces in
1.4018 +other interpreters. This undocumented feature is no longer implemented.
1.4019 +Instead, variable tracing is used to keep the C-level environ array in sync
1.4020 +with the Tcl-level env array. This required adding TCL_TRACE_ARRAY support
1.4021 +to Tcl_TraceVar2 so that array names works properly. (BW)
1.4022 +*** POTENTIAL INCOMPATIBILITY ***
1.4023 +
1.4024 +2/18/98 (enhancement) Conditional compilation for unix systems (e.g.,
1.4025 +IRIX, SCO) that use f_bsize instead of st_blksize to determine disk block
1.4026 +size. (CCS)
1.4027 +
1.4028 +2/23/98 (bug fix) Fixed the emulation of polling selects in the threaded
1.4029 +version of the Unix notifier. The bug was showing up on a multiprocessor
1.4030 +as starvation of the notifier thread. (BW)
1.4031 +
1.4032 +----------------- Released 8.1a2, Feb 23 1998 -----------------------
1.4033 +
1.4034 +9/22/98 (bug fix) Changed the value of TCL_TRACE_ARRAY so it no longer
1.4035 +conflicts with the deprecated TCL_PARSE_PART1 flag. This should
1.4036 +improve portability of C code. (stanton)
1.4037 +
1.4038 +10/6/98 (bug fix) The compile procedure for "if" incorrectly attempted
1.4039 +to match against the literal string "if", resulting in a stack
1.4040 +overflow when "::if" was compiled. It also would incorrectly accept
1.4041 +"if" instead of "elsif" in later clauses. (stanton)
1.4042 +
1.4043 +10/15/98 (new feature) Added a "totitle" subcommand to the "string"
1.4044 +command to convert strings to capitalize the first character of a string
1.4045 +and lowercase all of the other characters. (stanton)
1.4046 +
1.4047 +10/15/98 (bug fix) Changed regexp and string commands to properly
1.4048 +handle case folding according to the Unicode character
1.4049 +tables. (stanton)
1.4050 +
1.4051 +10/21/98 (new feature) Added an "encoding" command to facilitate
1.4052 +translations of strings between different character encodings. See
1.4053 +the encoding.n manual entry for more details. (stanton)
1.4054 +
1.4055 +11/3/98 (bug fix) The regular expression character classification
1.4056 +syntax now includes Unicode characters in the supported
1.4057 +classes. (stanton)
1.4058 +
1.4059 +11/6/98 (bug fix) Variable traces were causing crashes when upvar
1.4060 +variables went out of scope. [Bug: 796] (stanton)
1.4061 +
1.4062 +11/9/98 (bug fix) "format" now correctly handles multibyte characters
1.4063 +in %s format strings. (stanton)
1.4064 +
1.4065 +11/10/98 (new feature) "regexp" now accepts three new switches
1.4066 +("-line", "-lineanchor", and "-linestop") that control how regular
1.4067 +expressions treat line breaks. See the regexp manual entry for more
1.4068 +details. (stanton)
1.4069 +
1.4070 +11/17/98 (bug fix) "scan" now correctly handles Unicode
1.4071 +characters. (stanton)
1.4072 +
1.4073 +11/17/98 (new feature) "scan" now supports XPG3 position specifiers
1.4074 +and the "%n" conversion character. See the "scan" manual entry for
1.4075 +more details. (stanton)
1.4076 +
1.4077 +11/17/98 (bug fix) The Tcl memory allocator now returns 8-byte aligned
1.4078 +chunks of memory which improves performance on Windows and avoids
1.4079 +crashes on other platforms. [Bug: 834] (stanton)
1.4080 +
1.4081 +11/23/98 (bug fix) Applied various regular expression performance bug
1.4082 +fixes supplied by Henry Spencer. (stanton)
1.4083 +
1.4084 +11/30/98 (bug fix) Fixed various thread related race conditions. [Bug:
1.4085 +880 & 607] (stanton)
1.4086 +
1.4087 +11/30/98 (bug fix) Fixed a number of memory overflow and leak
1.4088 +bugs. [Bug: 584] (stanton)
1.4089 +
1.4090 +12/1/98 (new feaure) Added support for Korean encodings. (stanton)
1.4091 +
1.4092 +12/1/98 (feature change) Changed the Tcl_EvalObjv interface to remove
1.4093 +the string and length arguments.
1.4094 +*** POTENTIAL INCOMPATIBILITY with previous alpha releases ***
1.4095 +
1.4096 +12/2/98 (bug fix) Fixed various bugs related to line feed
1.4097 +translation. [Bug: 887] (stanton)
1.4098 +
1.4099 +12/4/98 (new feature) Added a message catalog facility to help with
1.4100 +localizing Tcl scripts. Thanks to Mark Harrison for contributing the
1.4101 +initial implementation of the "msgcat" package. (stanton)
1.4102 +
1.4103 +12/7/98 (bug fix) The memory allocator was failing to update the
1.4104 +block list for large memory blocks that were reallocated into a
1.4105 +different address. [Bug: 933] (stanton)
1.4106 +
1.4107 +----------------- Released 8.1b1, Dec 10 1998 -----------------------
1.4108 +
1.4109 +12/22/98 (performance improvement) Improved the -command option of the
1.4110 +lsort command to better use the object system for improved
1.4111 +performance (about 5x speed up). Thanks to Syd Polk for suppling the
1.4112 +patch. [RFE: 726] (rjohnson)
1.4113 +
1.4114 +2/10/99 (bug fix) Restored the Tcl_ObjSetVar2/Tcl_ObjGetVar2
1.4115 +interfaces from 8.0 and renamed the Tcl_GetObjVar2/Tcl_SetObjVar2
1.4116 +interfaces to Tcl_GetVar2Ex and Tcl_SetVar2Ex. This should provide
1.4117 +better compatibility with 8.0. (stanton)
1.4118 +*** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases ***
1.4119 +
1.4120 +2/10/99 (bug fix) Made the eval interfaces compatible with 8.0 by
1.4121 +renaming Tcl_EvalObj to Tcl_EvalObjEx, renaming Tcl_Eval2 to
1.4122 +Tcl_EvalEx and restoring Tcl_EvalObj and Tcl_GlobalEvalObj interfaces
1.4123 +so they match Tcl 8.0. (stanton)
1.4124 +*** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases ***
1.4125 +
1.4126 +2/25/99 (bug fix/new feature) On Windows, the channel drivers for
1.4127 +consoles and serial ports now completely support file events. (redman)
1.4128 +
1.4129 +3/5/99 (bug fix) Integrated patches to fix various configure problems
1.4130 +that affected HP-UX-11, 64-bit IRIX, Linux, and Solaris. (stanton)
1.4131 +
1.4132 +3/9/99 (bug fix) Integrated various AIX related patches to improve
1.4133 +support for shared libraries. (stanton)
1.4134 +
1.4135 +3/9/99 (new feature) Added tcl_platform(user) to provide a portable
1.4136 +way to get the name of the current user. (welch)
1.4137 +
1.4138 +3/9/99 (new feature) Integrated the stub library mechanism contributed
1.4139 +by Jan Nijtmans, Paul Duffin, and Jean-Claude Wippler. This feature
1.4140 +should make it possible to write extensions that support multiple
1.4141 +versions of Tcl simultaneously. It also makes it possible to
1.4142 +dynamically load extensions into statically linked interpreters. This
1.4143 +patch includes the following changes:
1.4144 + - Added a Tcl_InitStubs() interface
1.4145 + - Added Tcl_PkgProvideEx, Tcl_PkgRequireEx, Tcl_PkgPresentEx,
1.4146 + and Tcl_PkgPresent.
1.4147 + - Added va_list versions of all VARARGS functions so they can be
1.4148 + invoked from wrapper functions.
1.4149 +See the manual for more information. (stanton)
1.4150 +
1.4151 +
1.4152 +3/10/99 (feature change) Replaced Tcl_AlertNotifier with
1.4153 +Tcl_ThreadAlert since the Tcl_AlertNotifier function relied on passing
1.4154 +internal data structures. (stanton)
1.4155 +*** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases ***
1.4156 +
1.4157 +3/10/99 (new feature) Added a Tcl_GetVersion API to make it easier to
1.4158 +check the Tcl version and patch level from C. (redman)
1.4159 +
1.4160 +3/14/99 (feature change) Tried to unify the TclpInitLibrary path
1.4161 +routines to look in similar places from Windows to UNIX. The new
1.4162 +library search path is: TCL_LIBRARY, TCL_LIBRARY/../tcl8.1, relative
1.4163 +to DLL (Windows Only) relative to installed executable, relative to
1.4164 +develop executable, and relative to compiled-in in location (UNIX
1.4165 +Only.) This fix included:
1.4166 + - Defining a TclpFindExecutable
1.4167 + - Moving Tcl_FindExecutable to a common area in tclEncoding.c
1.4168 + - Modifying the TclpInitLibraryPath routines.
1.4169 +(surles)
1.4170 +
1.4171 +3/14/99 (feature change) Added hooks for TclPro Wrapper to initialize
1.4172 +the location of the encoding files and libraries. This fix included:
1.4173 + - Adding the TclSetPerInitScript routine.
1.4174 + - Modifying the Tcl_Init routines to evaluate the non-NULL
1.4175 + pre-init script.
1.4176 + - Adding the Tcl_SetdefaultEncodingDir and Tcl_GetDefaultEncodingDir
1.4177 + routines.
1.4178 + - Modifying the TclpInitLibrary routines to append the default
1.4179 + encoding dir.
1.4180 +(surles)
1.4181 +
1.4182 +3/14/99 (feature change) Test suite now uses "test" namespace to
1.4183 +define the test procedure and other auxiliary procedures as well as
1.4184 +global variables.
1.4185 + - Global array testConfige is now called ::test::testConfig.
1.4186 + - Global variable VERBOSE is now called ::test::verbose, and
1.4187 + ::test::verbose no longer works with numerical values. We've
1.4188 + switched to a bitwise character string. You can set
1.4189 + ::test::verbose by using the -verbose option on the Tcl command
1.4190 + line.
1.4191 + - Global variable TESTS is now called ::test::matchingTests, and
1.4192 + can be set on the Tcl command line via the -match option.
1.4193 + - There is now a ::test::skipTests variable (works similarly to
1.4194 + ::test::matchTests) that can be set on the Tcl command line via
1.4195 + the -match option.
1.4196 + - The test suite can now be run in any working directory. When
1.4197 + you run "make test", the working directory is nolonger switched
1.4198 + to ../tests.

1.4202 +--------------- Released 8.1b2, March 16, 1999 ----------------------
1.4203 +
1.4204 +3/18/99 (bug fix) Fixed missing/incorrect characters in shift-jis table
1.4205 +(stanton)
1.4206 +
1.4207 +3/18/99 (feature change) The glob command ignores the
1.4208 +FS_CASE_IS_PRESERVED bit on file systesm and always returns
1.4209 +exactly what it gets from the system. (stanton)
1.4210 +*** POTENTIAL INCOMPATIBILITY ***
1.4211 +
1.4212 +3/19/99 (new feature) Added support for --enable-64bit. For now,
1.4213 +this is only supported on Solaris 7 64bit (SunOS 5.7) using the Sun
1.4214 +compiler. (redman)
1.4215 +
1.4216 +3/23/99 (bug fix) Fixed fileevents and gets on Windows consoles and
1.4217 +serial devices so that non-blocking channels do not block on partial
1.4218 +input lines. (redman)
1.4219 +
1.4220 +3/23/99 (bug fix) Added a new Tcl_ServiceModeHook interface.
1.4221 +This is used on Windows to avoid the various problems that people
1.4222 +have been seeing where the system hangs when tclsh is running
1.4223 +outside of the event loop. As part of this, renamed
1.4224 +TcapAlertNotifier back to Tcl_AlertNotifier since it is public.
1.4225 +(stanton)
1.4226 +
1.4227 +3/23/99 (feature change) Test suite now uses "tcltest" namespace to
1.4228 +define the test procedure and other auxiliary procedures as well as
1.4229 +global variables. The previously chosen "test" namespace was thought
1.4230 +to be too generic and likely to create conflits.

1.4237 +3/24/99 (bug fix) Fix cases where expr would incorrect return
1.4238 +a floating point value instead of an integer. (stanton)
1.4239 +
1.4240 +3/25/99 (bug fix) Added ASCII to big5 and gb2312 encodings.
1.4241 +(stanton)
1.4242 +
1.4243 +3/25/99 (feature change) Changed so aliases are invoked at current
1.4244 +scope in the target interpreter instead of at the global scope. This
1.4245 +was an incompatibility introduced in 8.1 that is being removed.
1.4246 +(stanton)
1.4247 +*** POTENTIAL INCOMPATIBILITY with previous beta releases ***
1.4248 +
1.4249 +3/26/99 (feature change) --enable-shared is now the default and build

1.4251 +library and shell.
1.4252 +*** POTENTIAL INCOMPATIBILITY ***
1.4253 +
1.4254 +3/29/99 (bug fix) Removed the stub functions and changed the stub
1.4255 +macros to just use the name without params. Pass &tclStubs into the
1.4256 +interp (don't use tclStubsPtr because of collisions with the stubs on
1.4257 +Solaris). (redman)
1.4258 +
1.4259 +3/30/99 (bug fix) Loadable modules are now unloaded at the last
1.4260 +possible moment during Tcl_Finalize to fix various exit-time crashes.
1.4261 +(welch)
1.4262 +
1.4263 +3/30/99 (bug fix) Tcl no longer calls setlocale(). It looks at
1.4264 +env(LANG) and env(LC_TYPE) instead. (stanton)
1.4265 +
1.4266 +4/1/99 (bug fix) Fixed the Ultrix multiple symbol definition problem.
1.4267 +Now, even Tcl includes a copy of the Tcl stub library. (redman)
1.4268 +
1.4269 +4/1/99 (bug fix) Internationalized the registry package.
1.4270 +
1.4271 +4/1/99 (bug fix) Changed the implemenation of Tcl_ConditionWait and
1.4272 +Tcl_ConditionNotify on Windows. The new algorithm eliminates a race
1.4273 +condition and was suggested by Jim Davidson. (welch)
1.4274 +
1.4275 +4/2/99 (new apis) Made various Unicode utility functions public.
1.4276 +Tcl_UtfToUniCharDString, Tcl_UniCharToUtfDString, Tcl_UniCharLen,
1.4277 +Tcl_UniCharNcmp, Tcl_UniCharIsAlnum, Tcl_UniCharIsAlpha,

1.4279 +Tcl_UniCharIsUpper, Tcl_UniCharIsWordChar, Tcl_WinUtfToTChar,
1.4280 +Tcl_WinTCharToUtf (stanton)
1.4281 +
1.4282 +4/2/99 (feature change) Add new DDE package and removed the Tk
1.4283 +send command from the Windows version. Changed DDE-based send
1.4284 +code into "dde eval" command. The DDE package can be loaded
1.4285 +into tclsh, not just wish. Windows only. (redman)
1.4286 +
1.4287 +4/5/99 (bug fix) Changed safe-tcl so that the encoding command
1.4288 +is an alias that masks out the "encoding system" subcommand.
1.4289 +(redman)
1.4290 +
1.4291 +4/5/99 (bug fix) Configure patches to improve support for
1.4292 +OS/390 and BSD/OS 4.*. (stanton)
1.4293 +
1.4294 +4/5/99 (bug fix) Fixed crash in the clock command that occurred
1.4295 +with negative time values in timezones east of GMT. (stanton)
1.4296 +
1.4297 +4/6/99 (bug fix) Moved the "array set" C level code into a common
1.4298 +routine (TclArraySet). The TclSetupEnv routine now uses this API to
1.4299 +create an env array w/ no elements. This fixes the bug caused when
1.4300 +every environ varaible is removed, and the Tcl env variable is
1.4301 +synched. If no environ vars existed, the Tcl env var would never be
1.4302 +created. (surles)

1.4314 +focus.test for Tk hanging. (redman)
1.4315 +
1.4316 +4/13/99 (bug fix) Fixed bug where socket -async combined with
1.4317 +fileevent for writing did not work under Windows NT. (redman)
1.4318 +
1.4319 +4/13/99 (encoding fix) Restored the double byte definition of GB2312
1.4320 +and added the EUC-CN encoding. EUC-CN is a variant of GB2312 that
1.4321 +shifts the characters into bytes with the high bit set and includes
1.4322 +ASCII as a subset. (stanton)
1.4323 +
1.4324 +4/27/99 (bug fix) Added 'extern "C" {}' block around the stub table
1.4325 +pointer declaration so the stub library can be used from C++. (stanton)
1.4326 +
1.4327 +--------------- Released 8.1 final, April 29, 1999 ----------------------
1.4328 +
1.4329 +4/22/99 (bug fix) Changed Windows NT socket implementation to avoid
1.4330 +creating a communication window. This avoids the problem where the
1.4331 +system hangs waiting for tclsh to respond to a system-wide synchronous
1.4332 +broadcast (e.g. if you change system colors). (redman)
1.4333 +
1.4334 +4/22/99 (bug fix) Added call to TclWinInit from TclpInitPlatform when
1.4335 +building a static library since DllMain will not be invoked. This
1.4336 +could break old code that explicitly called TclWinInit, but should be
1.4337 +simpler in the long run. (stanton)

1.4342 +
1.4343 +4/28/99 (bug fix) Changed internal Tcl_Obj usage to avoid freeing the

1.4345 +freed. This makes it easier to debug extensions. (stanton)
1.4346 +
1.4347 +4/30/99 (bug fix) Fixed a memory leak in CommandComplete. (stanton)
1.4348 +
1.4349 +5/3/99 (bug fix) Fixed a bug where the Tcl_ObjType was not being set
1.4350 +in a duplicated Tcl_Obj. [Bug: 1975, 2047] (stanton)
1.4351 +
1.4352 +5/3/99 (bug fix) Changed Tcl_ParseCommand to avoid modifying eval'ed
1.4353 +strings that are already null terminated. [Bug: 1793] (stanton)
1.4354 +
1.4355 +5/3/99 (new feature) Applied Jeff Hobbs's string patch which includes
1.4356 +the following changes:
1.4357 + - added new subcommands: equal, repeat, map, is, replace
1.4358 + - added -length option to "string compare|equal"
1.4359 + - added -nocase option to "string compare|equal|match"
1.4360 + - string and list indices can be an integer or end?-integer?.
1.4361 + - added optional first and last index args to string toupper, et al.
1.4362 +See the string.n manual entry for more details about the new string
1.4363 +features. [Bug: 1845] (stanton)

1.4372 +provides a significant startup speed improvement. (stanton)
1.4373 +
1.4374 +5/12/99 (bug fix) Replaced the per-interpreter regexp cache with a
1.4375 +per-thread cache. Changed the Regexp object to take advantage of this
1.4376 +extra cache. Added a reference count to the TclRegexp type so regexps
1.4377 +can be shared by multiple objects. Removed the per-interp regexp cache
1.4378 +from the interpreter. Now regexps can be used with no need for an
1.4379 +interpreter. This set of changes should provide significant speed
1.4380 +improvements for many Tcl scripts. [Bug: 1063] (stanton)
1.4381 +
1.4382 +5/14/99 (bug fix) Durining initialization on Unix, Tcl now extracts the
1.4383 +encoding subfield from the LANG/LC_ALL environment variables in cases
1.4384 +where the locale is not found in the built-in locale table. It also
1.4385 +attempts to initialize the locale subsystem so X11 is happy. [Bug: 1989]

1.4393 +statement. (stanton)
1.4394 +
1.4395 +5/18/99 (bug fix) Modified initialization code on Windows to avoid
1.4396 +inherenting closed or invalid channels. If the standard input is

1.4398 +back to the standard Tk window console. (stanton)
1.4399 +
1.4400 +5/19/99 (bug fix) Added an extern "C" block around the entire tcl.h

1.4486 +requested by Jean-Luc Fontaine for his STOOOP package. (welch)
1.4487 +
1.4488 +7/3/99 (new feature) Added Tcl_SetNotifier (public API) and

1.4492 +
1.4493 +7/3/99 (new feature) Added a new variant of the "Trf core patch" from
1.4494 +Andreas Kupries that adds new C APIs Tcl_StackChannel,

1.4531 +notation for opening serial ports on Windows. (redman)
1.4532 +
1.4533 +7/21/99 (bug fix) Changed APIs in stub tables to use "unsigned long"

1.4585 +Nijtmans. [Bug: 2445] (hobbs)
1.4586 +
1.4587 +8/1/99 (bug fix) Changed Windows socket driver to terminate threads
1.4588 +by sending a message to the window rather than calling
1.4589 +TerminateThread(), which seems to leak about 4k from the helper
1.4590 +thread's stack space. (redman)
1.4591 +

1.4615 +
1.4616 +8/9/99 (internal api change) Removed the TclpMutexLock and TclpMutexUnlock
1.4617 +APIs and added a new exported api, Tcl_GetAllocMutex. These APIs are all for
1.4618 +the mutex used in the simple memory allocators. By making this change
1.4619 +we are able to substitute different implementations of the thread-related
1.4620 +APIs without having to recompile the Tcl core. (welch)
1.4621 +
1.4622 +8/9/99 (new C API) Tcl_GetChannelNames returns a list of open channel
1.4623 +names in the interpreter result. Still no Tcl-level version of this,
1.4624 +but server-like applications can use this to clean up files without
1.4625 +deleting interpreters. (welch)
1.4626 +
1.4627 +8/9/99 (bug fix) Traces were not firing on "info exists", which used to
1.4628 +happen in Tcl 7.6 and earlier. An "info exists" now fires a read trace,
1.4629 +if defined. This makes it possible to fully implement variables that
1.4630 +are defined via traces. (welch)
