Recent user-visible changes to Tcl: RCS: @(#) $Id: changes,v 1.136.2.16 2009/04/15 13:42:43 dgp Exp $ 1. No more [command1] [command2] construct for grouping multiple commands on a single command line. 2. Semi-colon now available for grouping commands on a line. 3. For a command to span multiple lines, must now use backslash-return at the end of each line but the last. 4. "Var" command has been changed to "set". 5. Double-quotes now available as an argument grouping character. 6. "Return" may be used at top-level. 7. More backslash sequences available now. In particular, backslash-newline may be used to join lines in command files. 8. New or modified built-in commands: case, return, for, glob, info, print, return, set, source, string, uplevel. 9. After an error, the variable "errorInfo" is filled with a stack trace showing what was being executed when the error occurred. 10. Command abbreviations are accepted when parsing commands, but are not recommended except for purely-interactive commands. 11. $, set, and expr all complain now if a non-existent variable is referenced. 12. History facilities exist now. See Tcl.man and Tcl_RecordAndEval.man. 13. Changed to distinguish between empty variables and those that don't exist at all. Interfaces to Tcl_GetVar and Tcl_ParseVar have changed (NULL return value is now possible). *** POTENTIAL INCOMPATIBILITY *** 14. Changed meaning of "level" argument to "uplevel" command (1 now means "go up one level", not "go to level 1"; "#1" means "go to level 1"). *** POTENTIAL INCOMPATIBILITY *** 15. 3/19/90 Added "info exists" option to see if variable exists. 16. 3/19/90 Added "noAbbrev" variable to prohibit command abbreviations. 17. 3/19/90 Added extra errorInfo option to "error" command. 18. 3/21/90 Double-quotes now only affect space: command, variable, and backslash substitutions still occur inside double-quotes. *** POTENTIAL INCOMPATIBILITY *** 19. 3/21/90 Added support for \r. 20. 3/21/90 List, concat, eval, and glob commands all expect at least one argument now. *** POTENTIAL INCOMPATIBILITY *** 21. 3/22/90 Added "?:" operators to expressions. 22. 3/25/90 Fixed bug in Tcl_Result that caused memory to get trashed. ------------------- Released version 3.1 --------------------- 23. 3/29/90 Fixed bug that caused "file a.b/c ext" to return ".b/c". 24. 3/29/90 Semi-colon is not treated specially when enclosed in double-quotes. ------------------- Released version 3.2 --------------------- 25. 4/16/90 Rewrote "exec" not to use select or signals anymore. Should be more Sys-V compatible, and no slower in the normal case. 26. 4/18/90 Rewrote "glob" to eliminate GNU code (there's no GNU code left in Tcl, now), and added Tcl_TildeSubst procedure. Added automatic tilde-substitution in many commands, including "glob". ------------------- Released version 3.3 --------------------- 27. 7/11/90 Added "Tcl_AppendResult" procedure. 28. 7/20/90 "History" with no options now defaults to "history info" rather than to "history redo". Although this is a backward incompatibility, it should only be used interactively and thus shouldn't present any compatibility problems with scripts. 29. 7/20/90 Added "Tcl_GetInteger", "Tcl_GetDouble", and "Tcl_GetBoolean" procedures. 30. 7/22/90 Removed "Tcl_WatchInterp" procedure: doesn't seem to be necessary, since the same effect can be achieved with the deletion callbacks on individual commands. *** POTENTIAL INCOMPATIBILITY *** 31. 7/23/90 Added variable tracing: Tcl_TraceVar, Tcl_UnTraceVar, and Tcl_VarTraceInfo procedures, "trace" command. 32. 8/9/90 Mailed out list of all bug fixes since 3.3 release. 33. 8/29/90 Fixed bugs in Tcl_Merge relating to backslashes and semi-colons. Mailed out patch. 34. 9/3/90 Fixed bug in tclBasic.c: quotes weren't quoting ]'s. Mailed out patch. 35. 9/19/90 Rewrote exec to always use files both for input and output to the process. The old pipe-based version didn't work if the exec'ed process forked a child and then exited: Tcl waited around for stdout to get closed, which didn't happen until the grandchild exited. 36. 11/5/90 ERR_IN_PROGRESS flag wasn't being cleared soon enough in Tcl_Eval, allowing error messages from different commands to pile up in $errorInfo. Fixed by re-arranging code in Tcl_Eval that re-initializes result and ERR_IN_PROGRESS flag. Didn't mail out patch: changes too complicated to describe. 37. 12/19/90 Added Tcl_VarEval procedure as a convenience for assembling and executing Tcl commands. 38. 1/29/91 Fixed core leak in Tcl_AddErrorInfo. Also changed procedure and Tcl_Eval so that first call to Tcl_AddErrorInfo need not come from Tcl_Eval. ----------------- Released version 5.0 with Tk ------------------ 39. 4/3/91 Removed change bars from manual entries, leaving only those that came after version 3.3 was released. 40. 5/17/91 Changed tests to conform to Mary Ann May-Pumphrey's approach. 41. 5/23/91 Massive revision to Tcl parser to simplify the implementation of string and floating-point support in expressions. Newlines inside [] are now treated as command separators rather than word separators (this makes newline treatment consistent throughout Tcl). *** POTENTIAL INCOMPATIBILITY *** 42. 5/23/91 Massive rewrite of expression code to support floating-point values and simple string comparisons. The C interfaces to expression routines have changed (Tcl_Expr is replaced by Tcl_ExprLong, Tcl_ExprDouble, etc.), but all old Tcl expression strings should be accepted by the new expression code. *** POTENTIAL INCOMPATIBILITY *** 43. 5/23/91 Modified tclHistory.c to check for negative "keep" value. 44. 5/23/91 Modified Tcl_Backslash to handle backslash-newline. It now returns 0 to indicate that a backslash sequence should be replaced by no character at all. *** POTENTIAL INCOMPATIBILITY *** 45. 5/29/91 Modified to use ANSI C function prototypes. Must set "USE_ANSI" switch when compiling to get prototypes. 46. 5/29/91 Completed test suite by providing tests for all of the built-in Tcl commands. 47. 5/29/91 Changed Tcl_Concat to eliminate leading and trailing white-space in each of the things it concatenates and to ignore elements that are empty or have only white space in them. This produces cleaner output from the "concat" command. *** POTENTIAL INCOMPATIBILITY *** 48. 5/31/91 Changed "set" command and Tcl_SetVar procedure to return new value of variable. 49. 6/1/91 Added "while" and "cd" commands. 50. 6/1/91 Changed "exec" to delete the last character of program output if it is a newline. In most cases this makes it easier to process program-generated output. *** POTENTIAL INCOMPATIBILITY *** 51. 6/1/91 Made sure that pointers are never used after freeing them. 52. 6/1/91 Fixed bug in TclWordEnd where it wasn't dealing with [] inside quotes correctly. 53. 6/8/91 Fixed exec.test to accept return values of either 1 or 255 from "false" command. 54. 7/6/91 Massive overhaul of variable management. Associative arrays now available, along with "unset" command (and Tcl_UnsetVar procedure). Variable traces have been completely reworked: interfaces different both from Tcl and C, and multiple traces may exist on same variable. Can no longer redefine existing local variable to be global. Calling sequences have changed slightly for Tcl_GetVar and Tcl_SetVar ("global" is now "flags"). Tcl_SetVar can fail and return a NULL result. New forms of variable-manipulation procedures: Tcl_GetVar2, Tcl_SetVar2, etc. Syntax of variable $-notation changed to support array indexing. *** POTENTIAL INCOMPATIBILITY *** 55. 7/6/91 Added new list-manipulation procedures: Tcl_ScanElement, Tcl_ConvertElement, Tcl_AppendElement. 56. 7/12/91 Created new procedure Tcl_EvalFile, which does most of the work of the "source" command. 57. 7/20/91 Major reworking of "exec" command to allow pipelines, more redirection, background. Added new procedures Tcl_Fork, Tcl_WaitPids, Tcl_DetachPids, and Tcl_CreatePipeline. The old "< input" notation has been replaced by "<< input" ("<" is for redirection from a file). Also handles error returns and abnormal terminations (e.g. signals) differently. *** POTENTIAL INCOMPATIBILITY *** 58. 7/21/91 Added "append" and "lappend" commands. 59. 7/22/91 Reworked error messages and manual entries to use ?x? as the notation for an optional argument x, instead of [x]. The bracket notation was often confused with the use of brackets for command substitution. Also modified error messages to be more consistent. 60. 7/23/91 Tcl_DeleteCommand now returns an indication of whether or not the command actually existed, and the "rename" command uses this information to return an error if an attempt is made to delete a non-existent command. *** POTENTIAL INCOMPATIBILITY *** 61. 7/25/91 Added new "errorCode" mechanism, along with procedures Tcl_SetErrorCode, Tcl_UnixError, and Tcl_ResetResult. Renamed Tcl_Return to Tcl_SetResult, but left a #define for Tcl_Return to avoid compatibility problems. 62. 7/26/91 Extended "case" command with alternate syntax where all patterns and commands are together in a single list argument: makes it easier to write multi-line case statements. 63. 7/27/91 Changed "print" command to perform tilde-substitution on the file name. 64. 7/27/91 Added "tolower", "toupper", "trim", "trimleft", and "trimright" options to "string" command. 65. 7/29/91 Added "atime", "mtime", "size", and "stat" options to "file" command. 66. 8/1/91 Added "split" and "join" commands. 67. 8/11/91 Added commands for file I/O, including "open", "close", "read", "gets", "puts", "flush", "eof", "seek", and "tell". 68. 8/14/91 Switched to use a hash table for command lookups. Command abbreviations no longer have direct support in the Tcl interpreter, but it should be possible to simulate them with the auto-load features described below. The "noAbbrev" variable is no longer used by Tcl. *** POTENTIAL INCOMPATIBILITY *** 68.5 8/15/91 Added support for "unknown" command, which can be used to complete abbreviations, auto-load library files, auto-exec shell commands, etc. 69. 8/15/91 Added -nocomplain switch to "glob" command. 70. 8/20/91 Added "info library" option and TCL_LIBRARY #define. Also added "info script" option. 71. 8/20/91 Changed "file" command to take "option" argument as first argument (before file name), for consistency with other Tcl commands. *** POTENTIAL INCOMPATIBILITY *** 72. 8/20/91 Changed format of information in $errorInfo variable: comments such as ("while" body line 1) are now on separate lines from commands being executed. *** POTENTIAL INCOMPATIBILITY *** 73. 8/20/91 Changed Tcl_AppendResult so that it (eventually) frees large buffers that it allocates. 74. 8/21/91 Added "linsert", "lreplace", "lsearch", and "lsort" commands. 75. 8/28/91 Added "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 !!, !<num>, and ^<old>^<new> 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 - \<newline> 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, >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 <unistd.h> 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 an 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 <karl@hammer1.ops.NeoSoft.com>. 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 un-aliasing 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 <drh@acm.org> 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 pre-init 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. This makes it easier to debug extensions. (stanton) 4/30/99 (bug fix) Fixed a memory leak in CommandComplete. (stanton) 5/3/99 (bug fix) Fixed a bug where the Tcl_ObjType was not being set in a duplicated Tcl_Obj. [Bug: 1975, 2047] (stanton) 5/3/99 (bug fix) Changed Tcl_ParseCommand to avoid modifying eval'ed strings that are already null terminated. [Bug: 1793] (stanton) 5/3/99 (new feature) Applied Jeff Hobbs's string patch which includes the following changes: - added new subcommands: equal, repeat, map, is, replace - added -length option to "string compare|equal" - added -nocase option to "string compare|equal|match" - string and list indices can be an integer or end?-integer?. - added optional first and last index args to string toupper, et al. See the string.n manual entry for more details about the new string features. [Bug: 1845] (stanton) 5/6/99 (new feature) Added Tcl_UtfNcmp and Tcl_UtfNcasecmp to make Utf string comparision easier. (stanton) 5/7/99 (bug fix) Improved OS/390 support. [Bug: 1976, 1997] (stanton) 5/12/99 (bug fix) Changed Windows initialization code to avoid using GetUserName system call in favor of the env(USERNAME) variable. This provides a significant startup speed improvement. (stanton) 5/12/99 (bug fix) Replaced the per-interpreter regexp cache with a per-thread cache. Changed the Regexp object to take advantage of this extra cache. Added a reference count to the TclRegexp type so regexps can be shared by multiple objects. Removed the per-interp regexp cache from the interpreter. Now regexps can be used with no need for an interpreter. This set of changes should provide significant speed improvements for many Tcl scripts. [Bug: 1063] (stanton) 5/14/99 (bug fix) Durining initialization on Unix, Tcl now extracts the encoding subfield from the LANG/LC_ALL environment variables in cases where the locale is not found in the built-in locale table. It also attempts to initialize the locale subsystem so X11 is happy. [Bug: 1989] (stanton) 5/14/99 (bug fix) Applied the patch to fix 100-year and 400-year boundaries in leap year code, from Isaac Hollander. [Bug: 2066] (redman) 5/14/99 (bug fix) Fixed a crash caused by a failure to reset the result before evaluating the test expression in an uncompiled for statement. (stanton) 5/18/99 (bug fix) Modified initialization code on Windows to avoid inherenting closed or invalid channels. If the standard input is anything other than a console, file, serial port, or pipe, then we fall back to the standard Tk window console. (stanton) 5/19/99 (bug fix) Added an extern "C" block around the entire tcl.h header file to avoid C++ linkage issues. (redman) 5/19/99 (new feature) Applied Jeff Hobb's patch to add Tcl_StringCaseMatch to support case insensitive glob style matching and Tcl_UniCharIs* character classification functions. (stanton) 5/20/99 (bug fix) Added the directory containing the executuble and the ../lib directory relative to that to the auto_path variable. (redman) --------------- Released 8.1.1, May 25, 1999 ---------------------- 5/21/99 (bug fix) Fixed launching command.com on Win95/98, no longer hangs. [Bug: 2105] (redman) 5/28/99 (bug fix) Fixed bug where dde calls were being passed an invalid dde handle. [Bug: 2124] (stanton) 6/1/99 (bug fix) Small configure.in patches. [Bug: 2121] (stanton) 6/1/99 (bug fix) Applied latest regular expression patches to fix an infinite loop bug and add support for testing whether a string could match with additional input. [Bug: 2117] (stanton) 6/2/99 (bug fix) Fixed incorrect computation of relative ordering in Utf case-insensitive comparison. [Bug: 2135] (stanton) 6/3/99 (bug fix) Fxied bug where string equal/compare -nocase reported wrong result on null strings. [Bug: 2138] (stanton) 6/4/99 (new feature) Windows build now uses Cygwin tools plus GNU make and autoconf to build static/dynamic and debug/nodebug.

Still no Tcl-level version of this, but server-like applications can use this to clean up files without deleting interpreters. (welch) 8/9/99 (bug fix) Traces were not firing on "info exists", which used to happen in Tcl 7.6 and earlier. An "info exists" now fires a read trace, if defined. This makes it possible to fully implement variables that are defined via traces. (welch) 8/10/99 (bug fix) Fixed Brent's changes so that they work on Windows.
