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