Changes that aren't backward compatible -are marked specially. +Recent user-visible changes to Tcl: RCS: @(#) $Id$ -3/16/91 (bug fix) Modified tkWindow.c to remove Tk's Tcl commands from -the interpreter when the main window is deleted (otherwise there will -be dangling pointers to the non-existent window). +1. No more [command1] [command2] construct for grouping multiple +commands on a single command line. -3/16/91 (bug fix) Modified tkColor.c not to free black or white colors: -some X servers get upset at this. +2. Semi-colon now available for grouping commands on a line. -3/18/91 (bug fix) Modified tkShare.c to fix bug causing "DeleteGroup -couldn't find group on shareList" panic. +3. For a command to span multiple lines, must now use backslash-return +at the end of each line but the last. -3/18/91 (bug fix) Several changes to tkListbox.c and tkScrollbar.c to -handle listboxes (and scrollbars) with zero total entries in them. +4. "Var" command has been changed to "set". -3/22/91 (bug fix) Fixed a few ='s in tkListbox.c that should be ==. +5. Double-quotes now available as an argument grouping character. -3/22/91 (bug fix) Fixed error in main.c that caused BadWindow errors -in some cases where wish scripts invoke "destroy .". +6. "Return" may be used at top-level. -3/23/91 (new feature) Added Tk_CancelIdleCall to remove Tk_DoWhenIdle -handler. +7. More backslash sequences available now. In particular, backslash-newline +may be used to join lines in command files. -3/23/91 (bug fix and new feature) Added -name option to main.c, made -it more clever about choosing name (was always using the name "wish" -on most Unix systems). +8. New or modified built-in commands: case, return, for, glob, info, +print, return, set, source, string, uplevel. -3/23/91 (new feature) Added TK_CONFIG_STRING option to Tk_ConfigureWidget, -used it to malloc strings for various widget options that used to be -Tk_Uid's (e.g. button text, message strings, etc.). Eliminates core -leaks when values change in continuous non-repeating fashion. +9. After an error, the variable "errorInfo" is filled with a stack +trace showing what was being executed when the error occurred. -3/29/91 (new feature) Added Tk_Preserve, Tk_Release, and -Tk_EventuallyFree procedures to help manage widget records and avoid -premature memory free-ing. +10. Command abbreviations are accepted when parsing commands, but +are not recommended except for purely-interactive commands. -4/4/91 (bug fix) Fixed problem in tkWm.c where top-level window geometry -wasn't tracking correctly when wm-induced size change also changed window -position (e.g. menus wouldn't be displayed at the right places). +11. $, set, and expr all complain now if a non-existent variable is +referenced. -4/5/91 (new feature) Added "invoke" option to widget command for buttons, -check buttons, and radio buttons. +12. History facilities exist now. See Tcl.man and Tcl_RecordAndEval.man. -4/5/91 (new feature) Added "unpack" option to "pack" command. +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 *** -4/5/91 (bug fix) Changed tkPack.c to use new Tk_Preserve code and be -more careful about window deletions that occur while repacking is in -progress. +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 *** -4/6/91 (bug fix) Major overhaul of deletion code in all widgets to use -Tk_Preserve and Tk_Release. Should fix many problems. +15. 3/19/90 Added "info exists" option to see if variable exists. -4/6/91 (bug fix) Changed "winfo children" to generate correct lists -when child names have embedded spaces. +16. 3/19/90 Added "noAbbrev" variable to prohibit command abbreviations. -4/6/91 (new feature) Added "screenheight" and "screenwidth" options to -"winfo". +17. 3/19/90 Added extra errorInfo option to "error" command. -4/18/91 (bug fix) Binding mechanism didn't correctly handle very long -%-substitutions in commands (e.g. long path names) and caused memory -to be overwritten. Modified tkBind.c to fix. +18. 3/21/90 Double-quotes now only affect space: command, variable, +and backslash substitutions still occur inside double-quotes. +*** POTENTIAL INCOMPATIBILITY *** ----------------------- Release 1.1, 4/18/91 ------------------------- +19. 3/21/90 Added support for \r. -4/19/91 (bug fix) Inconsistent ICCCM handling of coordinates of reparented -windows causes windows to gradually walk south when moved or resized. -Fixed tkWm.c to patch around the problem. +20. 3/21/90 List, concat, eval, and glob commands all expect at least +one argument now. *** POTENTIAL INCOMPATIBILITY *** ----------------------- Release 1.2, 4/24/91 ------------------------- +21. 3/22/90 Added "?:" operators to expressions. -4/26/91 (new feature) Added -geometry and -display switches to wish. -Also wrote wish manual entry. +22. 3/25/90 Fixed bug in Tcl_Result that caused memory to get trashed. -5/3/91 (bug fix) Fixed bug in tkListbox.c that caused garbage to appear -at right edge of window when strings were to large to fit in window. +------------------- Released version 3.1 --------------------- -5/3/91 (bug fix) Fixed bug in tkListbox.c where topIndex wasn't getting -updated when elements were deleted: tended to cause errors in -communication with scrollbars. +23. 3/29/90 Fixed bug that caused "file a.b/c ext" to return ".b/c". -5/16/91 (bug fix) Fixed bug in tk3d.c, which caused core dumps when -consecutive points in a polygon were the same (happened with some -configurations of radio buttons, for example). +24. 3/29/90 Semi-colon is not treated specially when enclosed in +double-quotes. -5/16/91 (bug fix) Fixed main.c to allow stdin to be redirected. +------------------- Released version 3.2 --------------------- -6/1/91 (bug fix) Make sure that pointers are never used after being -freed. +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. -6/15/91 (bug fix) Fixed bug in tkBind.c that caused current binding -values to not always be printed correctly. +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". -6/15/91 (bug fix) Make sure that interpreters are always unregistered -when their main windows are deleted, and make wish delete the main -window before exiting. +------------------- Released version 3.3 --------------------- -8/21/91 (misfeature correction) Automatically set source of window -position to "user" in "wm geometry" command, unless it has been -explicitly set to "program". +27. 7/11/90 Added "Tcl_AppendResult" procedure. -9/5/91 (bug fix) Modified option code to accept '#' as a comment -character in .Xdefaults files, in addition to '!'. +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. -9/10/91 (misfeature correction) Changed binding mechanism so that -numeric %-sequences are output in decimal instead of hex. +29. 7/20/90 Added "Tcl_GetInteger", "Tcl_GetDouble", and "Tcl_GetBoolean" +procedures. -9/19/91 (bug fix) Fixed bug in Tk_DoOneEvent(1) where it wasn't -checking files and X connections properly so it missed events. +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 *** -10/6/91 (new feature) Reorganized tkBind.c to provide generic "binding -table" structure, which can be used to create bindings on items in -canvases as well as windows. +31. 7/23/90 Added variable tracing: Tcl_TraceVar, Tcl_UnTraceVar, +and Tcl_VarTraceInfo procedures, "trace" command. -10/6/91 (new feature) Upgraded buttons and menus to use new tracing -code in Tcl 6.0. Allows radio buttons and check buttons to both set -and clear themselves when associated variable changes. +32. 8/9/90 Mailed out list of all bug fixes since 3.3 release. -10/17/91 (bug fix) Fixed 2 bugs in listboxes: accidentally advanced the -selection when new entries were inserted in the listbox after the location -of the selected item(s), and goofed up on redisplay if selected item -was deleted and then selection was immediately lost. +33. 8/29/90 Fixed bugs in Tcl_Merge relating to backslashes and +semi-colons. Mailed out patch. -10/27/91 (bug fix) "pack unpack" wasn't telling Tk that it no longer -manages window; this led to core dumps in some situations. +34. 9/3/90 Fixed bug in tclBasic.c: quotes weren't quoting ]'s. +Mailed out patch. -10/31/91 (reorganization) Renamed manual entries so that they are no -more than 14 characters in length. +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. -10/31/91 (reorganization) Changed tk.h and tkInt.h so that tkInt.h -doesn't needed to be included by tk.h. +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. -11/3/91 (portability improvement) Eliminated use of "class" as a variable -name, since it's a reserved word in C++. +37. 12/19/90 Added Tcl_VarEval procedure as a convenience for +assembling and executing Tcl commands. -11/7/91 (reorganization) Many changes to upgrade for Tcl 6.1 including -use of Tcl hash tables instead of separate "Hash_" module. The "lib" -subdirectory is no longer needed in Tk. +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. ----------------------- Release 1.3, 11/7/91 ------------------------- +----------------- Released version 5.0 with Tk ------------------ -11/24/91 (bug fix) Fixed bug causing occasional errors if existing bindings -are modified (FindSequence in tkBind.c forget to set *maskPtr). +39. 4/3/91 Removed change bars from manual entries, leaving only those +that came after version 3.3 was released. -11/24/91 (bug fix) Used wrong hash table in Tk_GetColorByValue. Could -cause new entries to get created unnecessarily. +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 *** -12/2/91 (bug fix) Changed "bind" code to put backslashes in front of -special characters (e.g. [ or \) that appear in %-replacements, so that -they can be parsed cleanly. +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 *** -12/10/91 (bug fix) Manual entries had first lines that caused "man" program -to try weird preprocessor. Added blank comment lines to fix problem. +43. 5/23/91 Modified tclHistory.c to check for negative "keep" value. -1/2/92 (documentation cleanup) Changed manual entries for Tk_GetBitmap -and the like to make it more clear that the argument must be a Tk_Uid -and not a string. +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 *** -1/2/92 (bug fix) Fixed problem where scrollbars that were very short or -very narrow (too small to hold both arrows) could cause negative values -in calls to XClearArea, which crashed some servers. +45. 5/29/91 Modified to use ANSI C function prototypes. Must set +"USE_ANSI" switch when compiling to get prototypes. -1/2/92 (bug fix) Fixed bug in TkMeasureChars occurring when maxChars -is 0. Occasionally affected things like message window geometry. +46. 5/29/91 Completed test suite by providing tests for all of the +built-in Tcl commands. -1/3/92 (new feature) Added procedures Tk_GetJustify, Tk_GetAnchor, -Tk_GetCapStyle, and Tk_GetJoinStyle, plus support for these things -in Tk_ConfigureWidget. +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. ----------------------- Release 1.4, 1/10/92 ------------------------- +49. 6/1/91 Added "while" and "cd" commands. -1/12/92 (bug fix) TkMenubutton.c wasn't cleaning up mbPtr->varName -properly during menubutton cleanup if an error occurred during -menubutton creation. +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 *** -1/19/92 (bug fix) Fixed off-by-one bug in tkListbox.c that caused -scrollbars to display a slider that was too large. +51. 6/1/91 Made sure that pointers are never used after freeing them. -2/10/92 (bug fix) Tk_CreateFileHandler didn't correctly handle case -where new mask was specified for existing handler. +52. 6/1/91 Fixed bug in TclWordEnd where it wasn't dealing with +[] inside quotes correctly. -2/13/92 (bug fix) Tk_DeleteAllBindings wasn't correctly removing -bindings from the pattern table: only did the removal for the -first pattern in a pattern list. +53. 6/8/91 Fixed exec.test to accept return values of either 1 or +255 from "false" command. -2/15/92 (new feature) Added procedures Tk_DefineBitmap and -Tk_SizeOfBitmap. Tk_GetBitmapFromData is now considered obsolete -and probably shouldn't be used anymore. Tk_GetBitmapFromData -is now implemented by calling Tk_DefineBitmap and Tk_GetBitmap. +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 *** -2/15/92 (new feature) Added "curselection" and "select clear" options -to widget command for listboxes. +55. 7/6/91 Added new list-manipulation procedures: Tcl_ScanElement, +Tcl_ConvertElement, Tcl_AppendElement. -2/15/92 (new feature) Added Tk_3DBorderColor procedure. +56. 7/12/91 Created new procedure Tcl_EvalFile, which does most of the +work of the "source" command. -2/17/92 (relaxed limitations) Changed scrollbars so they no longer limit -the slider position to lie within the object's range: can scroll off the -end of an object, if the object permits it. Changed listboxes and -entries to explicitly prevent viewing off the ends. Also relaxed -listbox index checks so that out-of-range indices are automatically -adjust to fit within the listbox range. +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 *** -2/19/92 (bug fix) tkWindow.c tended to leave half-created windows around -if a new window's name was found to be in use already. Fixed to clean -them up. +58. 7/21/91 Added "append" and "lappend" commands. -2/22/92 (new feature) Added -anchor, -bitmap, -height, -textvariable, --width options to labels, buttons, check buttons, menu buttons, and radio -buttons. This means that (a) size can be controlled better, (b) bitmaps -can be displayed in any buttons, (c) the position of the text within the -button can be controlled, and (d) a button can be made to display the value -of a variable, continuously updating itself. Also changed -selector option -so that if it's specified as an empty string then no selector is drawn -for the button. +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. -2/22/92 (new feature) Changed menus to support bitmaps in menu entries: -added new -bitmap option for entries. +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 *** -2/26/92 (bug fix) "after" command, when invoked with just one argument, -called Tk_Sleep rather than registering a timer handler and looping on -Tk_DoOneEvent. As a result, it caused the application to become non- -responsive to X events during the sleep. Changed to use a Tk_DoOneEvent -loop so that it is responsive. +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. -2/26/92 (bug fix) Tk's main program didn't map the main window until -after the startup script returned. Changed to map the window as a -do-when-idle handler, so that scripts can cause the window to be -mapped immediately with a call to "update" or "after". +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. -2/28/92 (bug fix) "wm withdraw" wasn't working if invoked before window -was originally mapped: window got mapped anyway. Fixed so that the -window doesn't get mapped as long as it's withdrawn. +63. 7/27/91 Changed "print" command to perform tilde-substitution on +the file name. -2/29/92 (new feature) Can use "focus none" to clear input focus. +64. 7/27/91 Added "tolower", "toupper", "trim", "trimleft", and "trimright" +options to "string" command. -2/29/92 (bug fix) Fixed tkEvent.c to generate SubstructureNotify events -properly. These weren't being generated previously. +65. 7/29/91 Added "atime", "mtime", "size", and "stat" options to "file" +command. -2/29/92 (bug fix) Fixed entries so that newline characters can be properly -displayed (as `\x0a'). Had to change interface to TkDisplayChars in order -to do this (added flags argument). +66. 8/1/91 Added "split" and "join" commands. -2/29/92 (bug fix) Change Tk not to update size and position of top-level -windows directly during calls like Tk_ResizeWindow. Instead, wait until -actual event is received. This makes updates happen at same time as -callbacks. +67. 8/11/91 Added commands for file I/O, including "open", "close", +"read", "gets", "puts", "flush", "eof", "seek", and "tell". -3/6/92 (bug fix) TkMenubutton.c was dumping core when a menubutton was -pressed at a time when there was no associated menu for the button. - -3/6/92 (new feature) Added Tk script library directory with official -Tk initialization file "tk.tcl". Other procedures used by Tk are in -other files. Tk procedures and variables all have names starting -with "tk_". Also added Wish startup script "wish.tcl", which sources -both the Tk and Tcl startup scripts. This means that things like -auto-loading and abbreviation expansion are now available in wish. -Added new variables tk_library, tk_priv, and tk_version. - -3/6/92 (new feature) It's now possible to set bindings for whole -classes by using the class name in the bind command. For example, -"bind Button <Enter> {puts stdout Hi!}" will cause a message to be -printed whenever any mouse button is entered. Can also use "all" -to set bindings for all widgets. Widget-specific bindings override -class bindings which override "all" bindings. - -3/6/92 (reorganization) Changed buttons (all flavors) and listboxes to -eliminate all hard-wired behavior. Instead, default behavior is set -by class bindings in tk.tcl. Also set up class bindings for menus, -menubuttons, and entries, which previously had no default behavior at -all. Scrollbars and scales still have hard-wired behavior that can't -be overridden. - -3/7/92 (look-and-feel change) Changed listboxes and entries and menus -to use button 2 for scanning instead of button 3. This is more consistent -with the official Motif use of button 2 for dragging. - -3/10/92 (new features) Added more options to "winfo" command: screencells, -screendepth, screenmmheight, screenmmwidth, and screenvisual. - -3/13/92 (bug fix) Event sharing mechanism (tkShare.c) wasn't checking -to see whether window was mapped before sharing events with it. - -3/16/92 (bug fix) Tk_SetInternalBorderWidth was passing wrong window to -geometry-management procedures, causing core-dumps when menu buttons -had their border widths changed. - -3/16/92 (bug fix) Menus were setting their geometry directory rather -than using Tk_GeometryRequest mechanism. - -3/17/92 (new feature) Added -cursor option to all widgets to set the -active cursor for the widget. Also added TK_CONFIG_ACTIVE_CURSOR -configure type. - -3/18/92 (new feature) Implemented generalized screen coordinates to -allow resolution-independent specification in many cases (but pixel- -based coordinates are still OK). Added Tk_GetScreenMM(), -Tk_GetPixels(), new configure types TK_CONFIG_SCREEN_MM and -TK_CONFIG_PIXELS. Changed widgets to use this new configure types -wherever possible (a few of the more complex cases still haven't -been taken care of yet). Added "pixels" and "fpixels" options to -"winfo" command. - -3/18/92 (new feature) First cut at canvas widgets is done and part of -the official Tk now. Canvases display text and structured graphics, -and allow you to bind commands to events related to the text and -graphics. - -3/21/92 (new feature) Added new "place" command. It implements a -new geometry manager that provides fixed placement, rubber-sheet -placement, and combinations of the two. Eliminated the commands -"move", "resize", and "map" that were provided by main.c but never -officially supported; the placer provides all of this functionality. - -3/23/92 (bug fix) Fixed bug in tkWm.c where top-level windows were -occasionally not being given the right size. The problem occurred -when a string of resizes happened all in a row (such as deleting all -the windows in an application and then recreating them). - -3/23/92 (new feature) Added Tk_CoordsToWindow procedure and -"winfo containing" command. These may be used to locate the window -containing a given point. - -3/28/92 (new feature) Added "-exportselection" option to listboxes, -so that listbox selection need not necessarily be the X selection. - -4/12/92 (bug fix) Changed menu buttons to store name of menubutton -in the associated variable, rather than the name of the menu. This -is necessary in order to allow several menu buttons to share the -same menu. +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 *** -4/12/92 (bug fix) Fixed core dump that occurred in tkError.c when -removing the first error record from the error list. +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. -4/15/92 (bug fix) Fixed bug in tkBind.c that prevented <KeyPress-1> -event specifications from being processed correctly: the "1" was -treated as a button name rather than a keysym. +69. 8/15/91 Added -nocomplain switch to "glob" command. -4/18/92 (new feature) Added Tk_DefineCursor and Tk_UndefineCursor -procedures. +70. 8/20/91 Added "info library" option and TCL_LIBRARY #define. Also +added "info script" option. -4/18/92 (new feature) Major revision to listboxes. Can now scroll and -scan in both x and y, plus -exportselection option allows selection not -to be exported. The "view" widget command has been replaced by "xview" -and "yview", and the "scan" widget command has a new syntax. +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 *** -4/18/92 (new feature) Added -exportselection option to entries, so you -can select whether you want the entry selection to be the X selection -or not. - -4/24/92 (new features) Added TK_CONFIG_CUSTOM type to Tk_ConfigureWidget, -plus added new flags TK_CONFIG_NULL_OK, TK_CONFIG_DONT_SET_DEFAULT, -and TK_CONFIG_OPTION_SPECIFIED. Several other new types, such as -TK_CONFIG_CAP_STYLE, were also added as part of implementing canvases. - -4/29/92 (bug fix) Changed "-selector" default for menus to have separate -values for mono and color. - -4/30/92 (bug fix) Fixed bug in tkListbox.c where it occasionally generated -bogus scroll commands (last index less than first). +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 *** -4/30/92 (reorganization) Moved demos directory to "library/demos". +73. 8/20/91 Changed Tcl_AppendResult so that it (eventually) frees +large buffers that it allocates. ----------------------- Release 2.0, 5/1/92 ------------------------- +74. 8/21/91 Added "linsert", "lreplace", "lsearch", and "lsort" +commands. -5/2/92 (bug fix) Fixed problem in tkListbox.c where it was doing too many -redisplays after repeated insertions. Also reduced number of invocations -of scrollbar commands. +75. 8/28/91 Added "incr" and "exit" commands. -5/7/92 (portability improvement) Changed main.c not to use TK_EXCEPTION -flag; it isn't needed and it causes problems on some systems. +76. 8/30/91 Added "regexp" and "regsub" commands. -5/9/92 (bug fix) Plugged core leaks in tkListbox.c and tkBind.c +77. 9/4/91 Changed "dynamic" field in interpreters to "freeProc" (procedure +address). This allows for alternative storage managers. +*** POTENTIAL INCOMPATIBILITY *** -5/9/92 (bug fix) TkBind.c was accidentally deleting bindings during -attempts to print non-existent bindings. +78. 9/6/91 Added "index", "length", and "range" options to "string" +command. Added "lindex", "llength", and "lrange" commands. -5/11/92 (bug fix) Maximum name length for applications (name used in -"send" commands) was too short (only 20); increased to 1000. Also -fixed bug related to over-long names that caused core dumps. +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 *** -5/13/92 (bug fix) tkShare.c was using a dangling pointer if a share -group was deleted as a side-effect of a shared event. +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. -5/13/92 (bug fix) Various initialization and core leak problems in -tkGC.c, tkSend.c, tkMenu.c, tkEvent.c, tkCanvas.c, tkCanvPoly.c, -tkCanvLine.c, tkListbox.c, tkEntry.c. +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. -5/13/92 (bug fix) Empty entries could be scanned off the left edge, -displaying a garbage character. +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. -5/13/92 (bug fix) Fixed a few problems with window manager interactions, -such as tendency for windows to spontaneously shrink in size. By no -means are all of the problems fixed, though. +83. 9/22/91 Added "pwd" command. -5/13/92 (performance optimization) Changed Tk_GeometryRequest not to -invoke geometry manager unless requested size has changed. +84. 9/22/91 Renamed manual pages so that their filenames are no more +than 14 characters in length, moved to "doc" subdirectory. ----------------------- Release 2.1, 5/14/92 ------------------------- +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. -5/1/92 (new features) Added flags like TK_IDLE_EVENTS to Tk_DoWhenIdle, -plus added "idletasks" option to "update" command. Tk_DoWhenIdle arguments -look different now, but the change should be upward-compatible. +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. -5/17/92 (new feature/bug fix) Added support for VisibilityNotify events -to the "bind" command. For some reason they weren't supported previously. +----------------- Released version 6.0, 9/26/91 ------------------ -5/17/92 (new feature) Added "tkwait" command. +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. -5/17/92 (new feature) Added "grab" command. +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. -5/17/92 (new feature) Added "-width" option to messages. Also changed -messages to use the computed (i.e. desired) line length when displaying, -not the actual width of the window. +89. 10/3/91 Added "upvar" command. -5/17/92 (bug fixes) Did some more fiddling with tkWm.c in the hopes -of improving window manager interactions. Now there won't be more than -one configure request outstanding to the wm at a time. +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. -5/17/92 (bug fix) Arrowheads on canvas lines weren't being translated -or scaled correctly. +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. -5/20/92 (bug fix) Page-mode scrolling didn't work correctly for canvases -(wrong windowUnits was passed to scrollbars). +92. 10/17/91 Fixed problems with backslash sequences: \r support was +incomplete and \f and \v weren't supported at all. -5/20/92 (bug fix) Changed scrollbars not to lose highlight when pointer -leaves window with button down. Also changed redisplay to double-buffer -for smoother redraws. +93. 10/24/91 Added Tcl_InitHistory procedure. -5/21/92 (new feature) Added "gray50" and "gray25" as predefined bitmaps. +94. 10/24/91 Changed "regexp" to store "-1 -1" in subMatchVars that +don't match, rather than returning an error. -5/22/92 (new feature) Buttons can now be disabled using the "-state" and -"-disabledforeground configuration options. The "activate" and "deactivate" -widget commands for buttons are now obsolete and will go away soon. -Please change Tcl scripts not to use them. +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 *** -5/23/92 (new feature) Entries can now be disabled using the "-state" -config option. Also improved class bindings for entries to keep the -cursor visible in the window when operations occur. Also made slight -improvements in the way redisplay is done. +96. 10/27/91 Fixed bug in "scan" where it used hardwired constants for +sizes of floats and doubles instead of using "sizeof". -5/23/92 (new feature) Added "-textvariable" option to entries so that -the text in an entry can be tied to the value of a global variable in -a fashion similar to buttons. +97. 10/31/91 Fixed bug in tclParse.c where parse-related error messages +weren't being storage-managed correctly, causing spurious free's. -5/27/92 (new feature) Added "-textvariable" and "-anchor" options to -messages. +98. 10/31/91 Form feed and vertical tab characters are now considered +to be space characters by the parser. -5/28/92 (new feature) Added "-padx" and "-pady" and "-underline" options -to menubuttons. +99. 10/31/91 Added TCL_LEAVE_ERR_MSG flag to procedures like Tcl_SetVar. -5/28/92 (feature change) Changed "-width" and "-height" options on -all flavors of buttons and menubuttons so that they are orthogonal -to "-padx" and "-pady". It used to be that -width overrode -padx -(no padding). Now they accumulate. +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. -5/29/92 (new feature) Added "-disabledforeground" option to menus and -all flavors of buttons (can specify color for disabled things rather -than just using stipple to gray out). +101. 11/7/91 Switched to use "pid_t" and "uid_t" and other official +POSIC types and function prototypes. -5/29/92 (new features) Added many new options to menu entries: --activebackground, -background, -font, -state, -underline. The -"disable" and "enable" widget commands for menus are now obsolete -and will go away soon. Please change Tcl scripts not to use them. +----------------- Released version 6.1, 11/7/91 ------------------ -5/29/92 (new features) Added "atom" and "atomname" options to "winfo" -command. +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. -5/29/92 (new feature) Wrote tk_listboxSingleSelect procedure, which -can be used to change listbox behavior so that only a single item is -selected at once. +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. -6/1/92 (new feature) Added new modifier names "Meta" and "Alt" for -"bind" command. +104. 12/10/91 Manual entries had first lines that caused "man" program +to try weird preprocessor. Added blank comment lines to fix problem. -6/3/92 (new feature) Added "winfo toplevel" command. +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. -6/3/92 (new feature) Made several changes for greater Motif compliance, -including: - - menu retention if you click and release in the menu button, - - keyboard traversal of menus (see traversal.man) - - no widget flashing if you set $tk_strictMotif to 1 +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. -6/15/92 (bug fix) Fixed problem in tkBind.c where command string for a -binding could get reallocated while the command was being executed (e.g. -bindings that delete or change themselves). +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. -6/15/92 (bug fix) Don't allow "tabWidth" field to become zero in tkFont.c: -can cause core dumps for fonts that don't enough information to compute -tab widths. +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. -6/19/92 (bug fix) Fixed bug in binding mechanism that caused structure- -related events to be reported both to the correct window and its parent. +----------------- Released version 6.2, 1/10/92 ------------------ -7/14/92 (bug fix) Changed tkColor.c not to free colors for visual types -StaticGray or StaticColor. +109. 1/20/92 Config didn't have code to actually use "uid_t" variable +to set TCL_UIT_T #define. -7/15/92 (new feature) Text widgets now exist. They display any number of -lines of text with a variety of display formats, and include hypertext -facilities. See the manual page for details. +110. 2/10/92 Tcl_Eval didn't properly reset "numLevels" variable when +too-deep recursion occurred. -7/20/92 (bug fix) If a top-level window was put in the iconic state to -begin with, it could be deiconified with "wm deiconify .foo" until it had -first been deiconified by hand from the window manager. Tk was getting -confused and thought the window was mapped when it wasn't. +111. 2/29/92 Added "on" and "off" to keywords accepted by Tcl_GetBoolean. -7/29/92 (bug fix) Don't permit rectangles or ovals to have zero-sized -dimensions. Round up to at least one pixel. +112. 3/19/92 Config wasn't installing default version of strtod.c for +systems that don't have one in libc.a. -7/29/92 (new features) Major upgrade to canvases: - - new item types: arc, window, bitmap - - added Bezier spline support for lines and polygons - - rectangles and ovals now center their outlines on the shape, - rather than drawing them entirely inside the shape - - new "coords" and "bbox" widget commands - - new "-tags" option for all item types. - - new "-confine" option to prevent scrolling off edge of canvas. +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. -8/6/92 (new feature) Added "-width" and "-height" options to frames. -The "-geometry" option is now obsolete and should be removed from Tcl -scripts: it may go away in the future. +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. -8/7/92 (bug fix) Error messages in Tk_ParseArgv were sometimes including -the option name where they should have included its value. +115. 4/16/92 Fixed bug in tclUnixAZ.c where "read" command didn't +compute file size right for device files. ----------------------- Release 2.2, 8/7/92 ------------------------- +116. 4/23/92 Fixed but in tclCmdMZ.c where "trace vinfo" was overwriting +the trace command. -8/7/92 (bug fix) Changed tkCanvas.c to be more conservative in the area -it passes to XCopyArea. +----------------- Released version 6.3, 5/1/92 ------------------ -8/8/92 (bug fix) Fixed bug in tkTextDisp.c that sometimes caused core -dumps when text views changed (e.g. typing return on last line of screen). +117. 5/1/92 Added Tcl_GlobalEval. -8/8/92 (bug fix) Fixed bug in menu.tcl that caused errors when using -keyboard to traverse over separator menu entries. +118. 6/1/92 Changed auto-load facility to source files at global level. -8/10/92 (bug fix) Changed to use OPEN_MAX instead of MAX_FD to compute -maximum # of open files. +119. 6/8/92 Tcl_ParseVar wasn't always setting termPtr after errors, which +sometimes caused core dumps. -8/10/92 (bug fix) Canvases weren't updating scrollbars on window size -changes. They also weren't recentering canvases on window size changes. +120. 6/21/92 Fixed bug in initialization of regexp pattern cache. This +bug caused segmentation violations in regexp commands under some conditions. -8/10/92 (bug fix) There were still a few places where commands were being -invoked at local level instead of global level (e.g. commands associated -with buttons and menu entries). +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. -8/10/92 (bug fix) TkBind.c used to ignore explicit shift modifiers for -all keys (i.e. <Shift-Tab> was treated the same as <Tab>). Modified to -allow explicit request for shift modifier, like <Shift-Tab>. +122. 7/2/92 Fixed bug that caused 'string match ** ""' to return 0. -8/13/92 (feature change) Changed default fonts to request "Adobe" fonts -explicitly. +123. 7/2/92 Fixed bug in Tcl_CreateCmdBuf where it wasn't initializing +the buffer to an empty string. -8/16/92 (bug fixes) Modified tkCanvArc.c and tkTrig.c to increase slightly -the bounding boxes for arcs, in order to make sure that proper redisplay -occurs when arcs are moved (little turds were getting left behind). +124. 7/6/92 Fixed bug in "case" command where it used NULL pattern string +after errors in the "default" clause. -8/16/92 (bug fix) Modified tkCanvas.c not to redraw at all if the redisplay -area is off the screen. Also, only do a background clear for the portion -of the redraw area that is on-screen. Also, reduced size of off-screen -pixmaps used for redisplaying, which speeds up redisplay in some cases. +125. 7/25/92 Speeded up auto_load procedure: don't reread all the index +files unless the path has changed. -8/19/92 (bug fix) Canvases that were taller than wide were not being -redisplayed properly. +126. 8/3/92 Changed tclUnix.h to define MAXPATHLEN from PATH_MAX, not +_POSIX_PATH_MAX. -8/20/92 (new feature) Added Tk_CreateGenericHandler procedure for trapping -all X events (useful for tracing, watching non-Tk windows, etc.). +----------------- Released version 6.4, 8/7/92 ------------------ -8/21/92 (bug fix) Widgets weren't always being notified when they got -the focus back again (the problem had to do with grabs and menus in -particular). +127. 8/10/92 Changed tclBasic.c so that comment lines can be continued by +putting a backslash before the newline. -8/21/92 (new feature) Added "-state" option to scale widgets. +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. -8/22/92 (new feature) Changed tkBitmap.c to allow tilde-substitution -to occur in bitmap file names. +129. 8/25/92 Modified "format" command to allow " " and "+" flags, and +allow flags in any order. ----------------------- Release 2.3, 8/24/92 ------------------------- +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}". -8/27/92 (bug fix) Changes to -activebackground and -activeforeground options -for menubuttons were being lost. +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. -8/27/92 (bug fix) Entries were selecting last character when a B1-drag -occurred past the right edge of the text. +132. 9/14/92 Renamed manual entries to have extensions like .3 and .n, +and added "install" target to Makefile. -8/28/92 (bug fix) Fixed bug in canvases where a grab during a button -press caused the canvas state to lock up so that it didn't select a -new current item. +133. 9/18/92 Modified "unknown" command to emulate !!, !<num>, and +^<old>^<new> csh history substitutions. -9/7/92 (bug fix) Changed tkMenu.c to accept numerical menu indices that -are out of range; now it just rounds them off to the nearest existing -entry. +134. 9/21/92 Made the config script cleverer about figuring out which +switches to pass to "nm". -9/7/92 (bug fix) Fixed bug in tkTextDisp.c that caused core dumps when -invoking "yview -pickplace" widget command on texts that are too small -to hold any lines at all. +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. -9/11/92 (bug fix) Fixed bug in tkTextDisp.c that caused core dumps -when adding tags to non-existent lines. +136. 9/28/92 Fixed bug in auto_reset where it was unsetting variables +that might not exist. -9/11/92 (bug fix) Line items in canvases didn't permit an empty fill -color (i.e. couldn't make them transparent). +137. 10/7/92 Changed "parray" library procedure to print any array +accessible to caller, local or global. -9/14/92 (reorganization) Changed manual entries to use .1, .3, and .n -extensions. Added "install" target to Makefile to suggest how Tk should -be installed. +138. 10/15/92 Fixed bug where propagation of new environment variable +values among interpreters took N! time if there exist N interpreters. -9/16/92 (bug fix) Changed tkSend.c to always specify the root window of -screen 0 rather than using DefaultRootWindow. DefaultRootWindow doesn't -always go to screen 0 on displays with multiple screens, which can result -in send's not being possible between the screens. +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). -9/18/92 (new feature) Added three new options to "wm" command: "protocol", -"client", and "command". These provide support for window manager protocols -such as WM_DELETE_WINDOW and WM_TAKE_FOCUS, plus support for the -WM_CLIENT_MACHINE and WM_COMMAND properties. +140. 10/21/92 Fixed bug that caused lists to be incorrectly generated +for elements that contained backslash-newline sequences. -9/30/92 (new feature) Implemented color model support, including -"tk colormodel" command and Tk_GetColorModel and Tk_SetColorModel -procedures. These allow you to force mono operation even on a color -display. Also changed color allocation not to give errors when colors -run out, but just to switch to a mono color model. +141. 12/9/92 Added support for TCL_LIBRARY environment variable: use +it as library location if it's present. -10/1/92 (bug fixes) Fixed two bugs in tkTextBTree.c that caused core dumps -during text deletion. +142. 12/9/92 Added "info complete" command, Tcl_CommandComplete procedure. -10/5/92 (bug work-around) Changed tkColor.c to ignore errors when freeing -colors. This is needed to work around improper reference count management -for colormap entries under X11/NeWS. +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). -10/7/92 (new feature) Added support for different visual types, including -procedures Tk_SetWindowVisual and Tk_SetWindowColormap, plus macros -Tk_Visual, Tk_Depth, and Tk_Colormap. The code for this was contributed -by Paul Mackerras. +----------------- Released version 6.5, 12/17/92 ------------------ -10/7/92 (new feature) Added Tk_IsTopLevel macro. - -10/12/92 (bug fix) Fixed bug in tk.tcl that caused torn-off menus with -cascaded children not to track mouse motion correctly (the cascade -switched in response to mouse motions within the cascaded child). - -10/12/92 (new feature) Major changes to focus handling: -(a) Tk watches FocusIn and FocusOut events for focus changes, not Enter - and Leave, so it will work better with explicit-focus-model window - managers (e.g. mwm in default mode). -(b) Tk generates FocusIn and FocusOut events for the focus window now. - The old procedural interface (via Tk_CreateFocusHandler) is obsolete - and is no longer used inside Tk. It is still supported for - compatibility, but won't be for long. You should change your code - to use FocusIn and FocusOut events instead. -(c) The model for FocusIn and FocusOut events is different than the - one described in Xlib documentation. See the "focus" manual entry - for details. -(d) If there is no input focus then keyboard events are discarded. They - used to be directed to the mouse pointer window, although this wasn't - documented. The focus now defaults to the root window. -*** POTENTIAL INCOMPATIBILITY *** +144. 12/21/92 Changed config to look in several places for libc file. -10/15/92 (bug fix) Fixed text items in canvases where they didn't -display the insertion cursor if the item had no characters in it. - -10/26/92 (bug fix) Fixed bug in tkSelect.c that occasionally caused -BadWindow X protocol errors when retrieving the selection. Tk wasn't -making sure that a window existed before using it to retrieve the -selection. - -10/30/92 (feature change) Changed canvases so that if the scroll region -is smaller than the window and -confine is on, the scroll region isn't -forced to be centered in the window; it can be anywhere that meets the -confinement restrictions. - -11/2/92 (new feature) Added "winfo exists" command. - -11/5/92 (new feature) Changed DoWhenIdle handlers so that if a new -when-idle handler is created as a side-effect of another when-idle -handler, the new handler isn't invoked until Tk has first checked -for other events to process. - -11/6/92 (bug fixes, new features) Major overhaul of window manager -interface: -(a) Tk should now work with virtual-root window managers; -(b) windows will now place more accurately on the screen and stay where - they're supposed to; -(c) size changes handled more reliably; -(d) code now works robustly in the face of withdrawals followed - immediately by deiconifications. -(e) Added new procedure Tk_GetVRootInfo and new options to "winfo" command: - vrootx, vrooty, vrootwidth, vrootheight. -(f) Added "overrideredirect" option to "wm". -(g) Fixed bug where change in width-only via "wm geom" didn't always work - (min and max window sizes weren't being set properly for the wm). - -11/6/92 (bug fixes) Modified menus so that they work correctly with -virtual root window managers. Also fixed bug where menus didn't move -along with their associated windows, so that the menu popped up at -the old location of the window rather than its new location. - -11/9/92 (new constraint) Made it illegal to give windows names that -start with upper-case letters, since such names will goof up the -option database by appearing to be classes rather than names. +145. 12/23/92 Added "elseif" support to if. Also, "then", "else", and +"elseif" may no longer be abbreviated. *** POTENTIAL INCOMPATIBILITY *** -11/10/92 (new feature) Added Postscript output to canvases. +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. -11/13/92 (bug fix) Changed default for maximum size passed to window -manager from 1000000 (which causes some wm's to make windows too large -when "maximized") to the size of the display. +147. 1/6/93 Fixed bug whereby backslash-newline wasn't working when +typed interactively, or in "info complete". -11/14/92 (feature change) Major overhaul of menubuttons and pull-down -menus. Removed event-sharing code, including Tk_ShareEvents and -Tk_UnshareEvents. The -variable option for menubuttons has been -removed,and the "post" and "unpost" widget commands for menubuttons -no longer exist. The "post" widget command for menus no longer -allows a group option. The procedure tk_menus has been replaced -with a new procedure, tk_menuBar, which has a slightly different -interface. -*** POTENTIAL INCOMPATIBILITY *** - -11/20/92 (new features, feature changes) Major overhaul of grab -mechanism to produce more correct event streams. Also changed Tcl -commands to require explicit window for grab releases (makes it -possible for grabs to work on multiple displays simultaneously). -The old "grab none" command no longer exists, but new options -have been added: "current", "release", "set", and "status". -*** POTENTIAL INCOMPATIBILITY *** +148. 1/22/93 Fixed bugs in "lreplace" and "linsert" where close +quotes were being lost from last element before replacement or +insertion. -11/20/92 (new feature) Use TK_LIBRARY environment variable to set library -directory location, if it is defined. Otherwise fall back on usual -compiled-in value. +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. -11/25/92 (bug fix) "wm grid" command was using wrong window. +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. -11/29/92 (bug fix) Fixed core dump that occurred when trying to use -placer on top-level windows: return error instead. +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. -11/29/92 (bug fix) Selection retrieval wasn't making sure that the window -on whose behalf selection is being retrieved actually exists. +152. 2/1/93 Added "putenv" procedure to replace the standard system +version so that it will work correctly with Tcl's environment handling. -12/3/92 (new feature) Added support for Mode_switch key to support the -full ISO character set. Also added event handlers for MappingNotify -events so that Tk updates itself in response to keycode and modifier -changes. +----------------- Released version 6.6, 2/5/93 ------------------ -12/6/92 (bug fix) Ignore recursive attempts to destroy window. +153. 2/10/93 Fixed bugs in config script: missing "endif" in libc loop, +and tried to use strncasecmp.c instead of strcasecmp.c. -12/9/92 (new demos) Added "tcolor" and "rmt" demos. +154. 2/10/93 Makefile improvements: added RANLIB variable for easier +Sys-V configuration, added SHELL variable for SGI systems. -12/10/92 (new features) Added "yposition" widget command for menus, -changed "delete" widget command to take an optional second index, -and changed -command option for cascade entries so that it is -invoked when the entry is activated rather than when it is invoked. -*** POTENTIAL INCOMPATIBILITY *** +----------------- Released version 6.7, 2/11/93 ------------------ -12/12/92 (implementation change) Changed the procedures Tk_FreeBitmap, -Tk_NameOfBitmap, Tk_SizeOfBitmap, Tk_FreeCursor, Tk_NameOfCursor, and -Tk_FreeGC to require an addition Display argument. This is needed for -Tk to function correctly when an application has windows on multiple -displays. +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 *** -12/12/92 (new feature) Started creating a test suite. Right now it -only has a few tests. - -12/12/92 (new feature) Modified the packer so that a window can be -packed in descendants of its parent (used to be restricted to the -parent alone). This makes it possible to hide extra windows used -for geometry management. Also, can use generalized screen distances -in the "pack" command. - -12/16/92 (feature change) Boolean options such as -exportselection now -print as 0/1 rather than true/false (both the default and current values -print this way). This makes it easier to use these values in expressions. -*** 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). -12/16/92 (name change) The classes "RadioButton" and "CheckButton" have -been renamed "Radiobutton" and "Checkbutton" for consistency. From now -on widget class names will have exactly one capital letter. +155. 2/6/93 Changed "regsub" so that it overwrites the result variable +in all cases, even if there is no match. *** POTENTIAL INCOMPATIBILITY *** -12/16/92 (new feature) Added -setgrid option to listboxes. +156. 2/8/93 Added support for XPG3 %n$ conversion specifiers to "format" +command. -12/16/92 (new feature) The "destroy" command, and the "delete" widget -command for canvases, now accept any number of arguments, including -zero. +157. 2/17/93 Fixed bug in Tcl_Eval where errors due to infinite +recursion could result in core dumps. -12/16/92 (new feature) Changed internal TkBindError procedure to -Tk_BackgroundError and exported it to Tk clients. +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. -12/16/92 (option name change) Changed the place command's "dependents" -option to "slaves" for better consistency with documentation. +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 *** -12/16/92 (name changes) Renamed the "cursor*" options in entries and -canvases to "insert*". Also renamed the "cursor" index to "insert" and -the "cursor" widget command to "icursor". This was done to avoid -confusion between the mouse cursor and the insertion cursor. +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 *** ----------------------- Release 3.0, 12/17/92 ------------------------- - -12/17/92 (bug fix) Fixed dangling-pointer bug in canvases that occurred -if a <LeaveNotify> binding deleted the current item. - -12/18/92 (bug fix) Core dump occurred if "wm" invoked with no arguments. -Also, tkWm.c wasn't properly setting WM_CLASS property on application -startup. - -12/18/92 (incorrect documentation) Updated manual entries for Tk_FreeGC, -Tk_FreeCursor, and Tk_FreeBitmap to reflect new interface that requires -"display" argument. - -12/18/92 (missing documentation) Added documentation for the canvas -"postscript" command, which was missing in the 3.0 release. - -12/21/92 (bug fixes) There were lots of problems with the new installation -targets in the Makefiles, such as using "cp -f" and not installing -prolog.ps. Made several other miscellaneous improvements to Makefile. +161. 2/25/93 Fixed two memory-management problems having to do with +managing the old result during variable trace callbacks. -12/21/92 (bug fix) Arrowheads on canvas line items weren't moving properly -after coordinate changes made with the "coords" widget command. +162. 3/1/93 Added dynamic string library: Tcl_DStringInit, Tcl_DStringAppend, +Tcl_DStringFree, Tcl_DStringResult, etc. -12/21/92 (bug fix) If top-level window was initially withdrawn, couldn't -ever deiconify it again. - -12/21/92 (bug fix) Double-button event sequences didn't always trigger -properly when grabs were in effect. - -12/22/92 (bug fix) The packer didn't display any top or bottom windows -after a left or right expanded window, and vice versa. Also made the -distribution of space among expanded windows more even. - -12/28/92 (new features) Several improvements to selection: -(a) Added procedures Tk_ClearSelection and Tk_DeleteSelHandler. -(b) Added "clear" and "own" options to "selection" command, extended - "handle" option to delete handlers. -(c) Error returns from "selection handle" scripts are now turned into - selection retrieval errors ("no such selection") rather than an - empty selection. -(d) Tk responds automatically for targets APPLICATION (name of application, - so you can "send" to it) and WINDOW_NAME (name of window within - application. -(e) Added test file "select.test" to test suite. - -12/28/92 (bug fix) Fixed problem with flashing menus that occurred -because menu.tcl was willing to unpost and then immediately repost -the same menu. - -1/6/93 (bug fix) Test for UnmapNotify events in tkPack.c used = instead -of ==. - -1/21/93 (bug fix) Changed many widgets to eliminate use of -DefaultVisualofScreen, DefaultColormap, etc. and use the visuals -and colormaps for the actual windows instead. Also changed to -inherit colormaps and windows from parent by default. - -1/21/93 (new features) Added new winfo options "cells", "depth", and -"visual". - -1/23/93 (bug fix) Fixed problem with text display that could result -in negative XCopyArea heights being sent to X server. This causes some -servers (e.g. some versions of OpenWindows) to crash. - -1/25/93 (new feature) Added -postcommand option to menus, so that menus -can be reconfigured before each posting. - -1/29/93 (feature change) Changed %X and %Y in bindings so that they -refer to the virtual root rather than the true root. Although -potentially incompatible, this change should almost always "do the -right thing". +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 *** -1/31/93 (bug fix) Changed "send" code to grab server while updating -the registry property (before this fix, two programs could allocate -the same interpreter name if they started up simultaneously). In -order to make this fix I had to change the code for reclaiming -names of dead interpreters in a way that sometimes allows dead -interpreters to persist in the registry. - -2/1/93 (feature change) Changed entries to allow leftmost "visible" -character to be the end of the text (i.e. no characters actually visible). -This is needed so that the cursor can be displayed even if the last -actual character is too wide to fit in the window. - -2/3/93 (bug fix) Fixed two bugs in tkFocus.c: (a) FocusIn events -were getting lost in some cases because the focus window hadn't been -created yet (e.g. new top-level window pops up underneath the mouse); -(b) Tk was accidentally triggering FocusOut events when the mouse -moved from a top-level window to one of its children. - -2/4/93 (new feature) Added "visibility" option to "tkwait" command to make -it easier to wait for a new window to appear on the screen. +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. ----------------------- Release 3.1, 2/5/93 ------------------------- - -2/10/93 (installation improvements) Makefile improvements: added RANLIB -variable for easier Sys-V installation, changed to use INCLUDE_DIR -properly, and added SHELL variable for SGI systems. - ----------------------- Release 3.2, 2/11/93 ------------------------- - -2/11/93 (new feature) Added "wm state" command, and improved wm so that -the right thing will happen if you invoke "wm iconify" when a window is -withdrawn. - -2/14/93 (bug fix) When -colormap option was used in generating Postscript -for canvases, Tk didn't add an extra space after the color command. - -2/14/93 (new feature) Changed "extern" declarations in tk.h to "EXTERN", -which will use the definition of EXTERN from tcl.h and work correctly -in C++ programs. - -2/18/93 (bug fix) Item-specific bindings weren't getting deleted from -canvas items when the items were deleted. As a result, they could -suddenly re-appear for new items if the new items were allocated a -record at the same addresses as the old ones. - -2/18/93 (feature reversal) Changed "after" back again, so that it sleeps -*without* responding to events when it is invoked with just one argument; -can always use tkwait plus after with additional arguments to achieve -the effect of responding to events. +165. 4/3/93 Eliminated "noSep" argument to Tcl_AppendElement, plus +TCL_NO_SPACE flag for Tcl_SetVar and Tcl_SetVar2. *** POTENTIAL INCOMPATIBILITY *** -2/20/93 (bug fix) Fixed bug in tkWindow.c where colormaps weren't being -set correctly for new top-level windows on different screens than their -parents (the bug results in X protocol errors: "invalid Colormap -parameter"). - -2/22/93 (bug fix) Changed "#!/usr/local/wish" in demo scripts to -"#!/usr/local/bin/wish" to reflect new location of binary. - -2/22/93 (new feature) Added new reliefs "groove" and "ridge". - -2/25/93 (new feature) Added new built-in bitmaps: "error", "hourglass", -"info", "question", "questhead", and "warning". Also added new demo in -"widget" to display all of these (under the Miscellaneous menu). - -2/25/93 (improved implementation) Changed DrawText procedure in -prolog for outputting Postscript from canvases to use stringwidth -instead of charpath+pathbbox: avoids limitcheck problems with long -strings, and also properly includes space characters in calculation. - -2/25/93 (bug fix) Fixed several bugs in library/menu.tcl that caused -menu traversal to mis-behave when menu had no entries. - -2/26/93 (new feature) Added "wm frame" command. +166. 4/3/93 Eliminated "flags" and "termPtr" arguments to Tcl_Eval. +*** POTENTIAL INCOMPATIBILITY *** -3/6/93 (bug fix) Mwm in click-to-focus mode was goofing up grabs so that -pull-down menus were sometimes unresponsive. Modified tk.tcl to ignore -the spurious B1-Enter events generated by mwm, plus modified tkGrab.c to -release simulated button grabs correctly. +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 *** -3/8/93 (bug fix) Tk had wrong interpretation of "lbearing" font metric, -which caused text to be displayed at the wrong horizontal position in -several places (labels/buttons, listboxes, canvas text, scales). This -change will cause slight changes in the way certain widgets are -displayed. - -3/12/93 (bug fix) Fixed core dumps that occurred in tkEntry.c because of -zero values in entryPtr->avgWidth. +168. 4/5/93 Changed Tcl_UnsetVar and Tcl_UnsetVar2 to return TCL_OK +or TCL_ERROR instead of 0 or -1. +*** POTENTIAL INCOMPATIBILITY *** -3/12/93 (bug fix) Tk_CoordsToWindow was using root coordinates always. -Changed to use virtual-root coordinates when a virtual-root window -manager is being used. Before this fix, "winfo containing" didn't -return the correct window under virtual-root window managers. - -3/18/93 (bug fix) Modified tkWm.c so that Tk doesn't fight with window -manager over position of window; it just takes what the window manager -gives it. - -3/21/93 (new feature) Changed menus to display cascade entries with -standard Motif arrows at right side.a +169. 4/5/93 Eliminated Tcl_CmdBuf structure and associated procedures; +can use Tcl_DStrings instead. +*** POTENTIAL INCOMPATIBILITY *** -3/22/93 (bug fix) Fixed bug in tkPack.c that was causing memory to -get trashed with the integer value 1. +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 *** -3/22/93 (bug fix) Canvas text didn't print correctly if it contained -an open paren (or other special character) immediately followed by -an octal digit. - -3/22/93 (bug fix) Text widgets didn't redisplay properly in cases -where two or more groups of lines both got taller at the same time -(e.g. from tag changes), causing two separate bit copies where the -first bit copy's target area overlapped the source area for -the second bit copy. - -4/1/93 (bug fix) Changed canvases to use ISO Latin-1 font encoding -if that's supported by the Postscript interpreter. Also added workaround -for bug in NeWSprint related to stipple fills. - -4/1/93 (bug fixes) Made various changes to focusing and grabs to -eliminate extraneous focus events and generally improve behavior. - -4/2/93 (bug fix) Modified tkWm.c not to wait indefinitely for the window -manager to map or reconfigure a window: this led to deadlock in some -situations, such as creating a new top-level window with a grab held. - -4/19/93 (bug fix) Fixed another bug in tkWm.c that caused windows to walk -across the screen in some situations. Also fixed problem where rapid -posting and unposting of cascaded submenus (or menus?) could cause Tk -to become confused about whether or not a window is mapped (added -TkWmUnmapWindow procedure to make top-level unmaps synchronous). - -4/24/93 (feature change) Changed the "after" command to allow times -less than or equal to 0, and to use 0 whenever they occur. - -4/26/93 (new feature) Implemented security check for "send" as proposed -by Bennett Todd: incoming sends are now rejected unless (a) xhost-style -access control is enabled and (b) the list of authorized hosts is -empty. In other words, you have to use xauth to use send. This feature -can be disabled by setting the TK_NO_SECURITY flag at compile-time. - -5/15/93 (improvement) Switched to use Tcl_PrintDouble whenever returning -real values as Tcl results. This potentially allows higher precision. -Switched to use %.15g whenever printing reals in Postscript files. -However, the change Tcl_PrintDouble causes incompatibilities. For -now, it's disabled with a macro in tclInt.h that redefines Tcl_PrintDouble. -Tk 4.0 will delete the macro, and you can also delete it now if you -want the better (but incompatible) behavior. - -5/19/93 (bug fix) Fixed divide-by-zero problem that could occur in -closeness calculations for canvas oval items. - -5/30/93 (bug fix) PROP and CONFIG were accidentally #defined to the same -value in tkBind.c, which could cause incorrect %-substitutions in event -bindings in a few exotic cases. - -6/4/93 (improvement) Changed to use GNU autoconfig for configuration. -Makefile format changed, and Tcl is no longer automatically included -in Tk releases. - -6/7/93 (bug fix) Fixed off-by-one error in rounding negative coordinates -during redisplay of canvases. - -6/9/93 (feature improvement) Modified default bindings for entries to -keep one character visible to the left of the cursor during backspaces. - -6/18/93 (feature improvement) Added patchlevel.h, for use in coordinating -future patch releases, and also added tk_patchLevel variable to make the -patch level available in scripts. +171. 4/14/93 Eliminated tclHash.h, and moved everything from it to +tcl.h +*** POTENTIAL INCOMPATIBILITY *** -6/26/93 (bug fix) Fixed numeric problems in scales that occurred with -very large scale values. +172. 4/15/93 Eliminated Tcl_InitHistory, made "history" command always +be part of interpreter. +*** POTENTIAL INCOMPATIBILITY *** -6/26/93 (bug fix) Polygon items in canvases could cause core dumps if -the "coords" widget command was used to add one new coordinate. +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 *** -6/26/93 (bug fix) Changed canvases to handle large stipple patterns -gracefully (stipples used to jump around during redisplay and lose -coherency). +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. -7/1/93 (syntax change, new feature) Implemented the new packer syntax -as described in the book. For now the old syntax will continue to be -supported too. Converting over is straightforward except (a) use -"-anchor" instead of "frame", and (b) padding is different (separate -internal and external padding, plus pad amounts are *on each side* -instead of total). Also added "pack propagate" command for keeping -the packer from setting the master's requested size. +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. -7/1/93 Changed copyright notices. The effect is the same as with the -old notices, but the new notices more clearly disclaim liability. +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). -7/7/93 (new feature) Added support for window stacking order. Windows -will now stack in the order created (most recent on top), plus "raise" -and "lower" commands may be used to restack (Tk_RestackWindow procedure -is available from C level). +200. 7/7/93 Added Tcl_SetRecursionLimit procedure so that the maximum +allowable nesting depth can be controlled for an interpreter from C. -7/7/93 (reorganization) Moved main.c to tkMain.c, reorganized it to -call Tcl_AppInit just like tclsh does, and added argv0 variable to contain -application name, and added default Tcl_AppInit procedure for wish. -Also added tkTest.c to hold C code for testing. +----------------- Released version 7.0 Beta 1, 7/9/93 ------------------ -7/7/93 (new feature) Added new Tk-specific "exit" command, which cleans -up properly before exiting. It replaces the Tcl "exit" command, and -can be used in place of "destroy .". +201. 7/12/93 Modified Tcl_GetInt and tclExpr.c so that full-precision +unsigned integers can be specified without overflow errors. -7/9/93 (new features) Added tk_dialog library procedure that creates -dialogs with a bitmap, message, and any number of buttons. Also changed -default tkerror procedure to use tk_dialog plus offer the user a chance -to see a Tcl stack trace. +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. --------------------- Release 3.3 Beta 1, 7/9/93 ------------------------- +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. -7/12/93 (configuration changes) Eliminated leading blank line in -configure script; provided separate targets in Makefile for installing -binary and non-binary information; fixed -lnsl and -lsocket handling -in configure; added autoconf support for fd_set type; check for various -typedefs like mode_t and size_t, and provide substitutes if they -don't exist; don't include tkAppInit.o in libtk.a; try to locate the -X includes and library in all of the standard places for various systems. +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 *** -7/14/93 (new feature) Modified tkMain.c so that it stores the value -of the -display command-line option into the DISPLAY environment -variable, if it is specified. +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. -7/15/93 (feature removal) Removed auto-initialization feature from -Tk_ConfigureWidget, so that you must once again initialize all fields -of a widget record before calling Tk_ConfigureWidget. This restores -the behavior back to what it was in Tk 3.2. +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 *** -7/16/93 (bug fix) Modified tkBind.c to ignore the Caps Lock modifier -unless it is explicitly requested in a binding. Without this fix, -buttons and menus and other things didn't work if the Caps Lock key -was active. +----------------- Released version 7.0 Beta 2, 7/21/93 ------------------ --------------------- Release 3.3 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. -7/21/93 (new feature) Change "make install" so that it will modify the -#! lines on demo scripts to reflect the place where the wish binary -is installed. +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. -7/23/93 (new feature) Added Tk_MainWindow procedure that returns the -main window associated with a Tcl interpreter. This is intended for -use by Tcl_AppInit and other initialization procedures. +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. -7/24/93 (configuration improvements) Changed configure script not to -omplain about "fd_set" missing if it's defined in <sys/select.h>. +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. -7/28/93 (bug fix) "Bad Match - parameter mismatch" errors were -sometimes occurring when several top-level windows got created -at the same time, due to wrong choice of sibling when stacking -windows. +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. -8/14/93 (new feature) Added support for tcl_prompt1 and tcl_prompt2 -to wish main program: makes prompts user-settable. +212. 7/29/93 Renamed regexp C functions so they won't clash with POSIX +regexp functions that use the same name. -8/19/93 (bug fix) Bindings to event sequences like "aD" never matched -because the Shift key has to be pressed before D. Modified Tk to -ignore extraneous keypresses if they are for modifier keys. +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. -8/26/93 (configuration changes) Added Tk_Init, modified Tcl_AppInit -procedures to use it and Tcl_Init. Added support for .wishrc file. +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. -8/28/93 (new feature) The main window is now a legitimate toplevel -widget. +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 *** --------------------- Release 3.3 Beta 3, 8/30/93 ------------------------- +216. 8/14/93 Added support for tcl_prompt1 and tcl_prompt2 variables +to tclMain.c: makes prompts user-settable. -9/2/93 (bug fix) The packer wasn't always relaying out a master after -changes to some of the configuration options of its slaves. +217. 8/14/93 Added asynchronous handlers (Tcl_AsyncCreate etc.) so +that signals can be taken cleanly by Tcl applications. -9/2/93 (bug fix) The binding mechanism made it impossible for patterns -like <Double-ButtonRelease-1> to ever match. +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. -9/2/93 (bug fix) Fixed core dump that occurred for bitmap canvas items -if Postscript is generated but no -bitmap option has been specified. +219. 8/16/93 Removed ENV_FLAGS from Makefile, so that there's no +official support for overriding setenv, unsetenv, and putenv. -9/4/93 (enhancement) Slight improvements to menu traversal: set menu -traversal bindings for menubar window in tk_menuBar, plus trigger -traversal on <Any-Alt-Keypress> instead of <Alt-Keypress>. +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. -9/9/93 (bug fix) Changed tkBind.c so that the Num_Lock key doesn't -prevent events from triggering bindings. +221. 8/21/93 Fixed bug in expr where "+", "-", and " " were all +getting treated as integers with value 0. -9/9/93 (bug fix) Changed tkOption.c to always fetch RESOURCE_MANAGER -property from root window of screen 0, rather than using default -screen. +222. 8/26/93 Added "tcl_interactive" variable to tclsh. -9/9/93 (bug fix) Entry widgets weren't allocating quite enough width -for themselves. Fixed this and changed the size computation to match -what's done for buttons and texts. +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. -9/16/93 (bug fix) Changed tkMain.c not to call exit C procedure directly; -instead always invoke "exit" Tcl command so that application can redefine -the command to do additional cleanup. +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). --------------------- Release 3.3, 9/29/93 ------------------------- +----------------- Released version 7.0 Beta 3, 8/28/93 ------------------ -9/30/93 (bug fix) Packer wasn't unmapping slaves when master got deleted. +225. 9/9/93 Renamed regexp.h to tclRegexp.h to avoid conflicts with system +include file by same name. -9/30/93 (bug fix) Binding event sequences such as <Right> were being -misprinted as ASCII characters such as "S". +226. 9/9/93 Added Tcl_DontCallWhenDeleted. -10/6/93 (bug fix) Canvases weren't unmapping window items when the canvas -got unmapped, which caused problems for window items whose windows weren't -descendants of the canvas (they got left on the screen). +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. -10/7/93 (feature change) NULL proc arguments to Tk_CreateFileHandler used -to have a special undocumented meaning (fd was display); eliminated this -special interpretation. +228. 9/17/93 Changed auto-exec to handle names that contain slashes +(i.e. don't use PATH for them). -10/7/93 (configuration change) Eliminated dependency of tkMain.c on -tkInt.h and tkConfig.h, so that it's easier for people to copy the file -out of the source directory to make modified versions. +229. 9/23/93 Fixed bug in "read" and "gets" commands where they didn't +clear EOF conditions. -10/8/93 (bug fix) 3.0 introduced a bug where the class of the application -wasn't being set properly, so options based on the application class -weren't triggering. Fixed by adding new argument to Tk_CreateMainWindow. +----------------- Released version 7.0, 9/29/93 ------------------ -10/11/93 (bug fix) Fixed bug in tkTextBTree.c where some deletions would -cause core dumps due to halfwayLinePtr not getting set correctly. +230. 10/7/93 "Scan" command wasn't properly aligning things in memory, +so segmentation faults could arise under some circumstances. -10/18/93 (bug fix) Fixed a couple of bugs that made it hard to actually -display N characters in an entry with "-width N" (tended to scroll the -entry so that only N-1 characters were visible at once). +231. 10/7/93 Fixed bug in Tcl_ConvertElement where it forgot to +backslash leading curly brace when creating lists. -10/22/93 (bug fix) During configuration, XINCLUDE_DIR and XLIBRARY_DIR -weren't overriding xmkmf like they were supposed to. +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. -10/23/93 (new feature) Allow negative scale factors in canvas "scale" -widget command. +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. -10/23/93 (bug fix) Grabs weren't being cleaned up right if the grab -window was deleted, causing core-dumps in some cases. +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. -10/23/93 (bug fix) tk_TextSelectTo wasn't checking to be sure that -the "anchor" mark exists. +235. 10/14/93 Fixed bug where "regsub" didn't set the output variable +if the input string was empty. -10/27/93 (bug fix) Fixed core dump that could occur in a text widget if -the scroll command modifies the text. +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. -11/1/93 (bug fix) Change texts so that the -yscrollcommand option is -invoked at display time, not when the window is re-layed out. This -eliminated various core dumps that could occur if -yscrollcommand modified -the text. +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. --------------------- Release 3.4, 11/04/93 ------------------------- +----------------- Released version 7.1, 11/4/93 ------------------ -Note: there is no 3.5 release. It was flawed and was thus withdrawn +Note: there is no 7.2 release. It was flawed and was thus withdrawn shortly after it was released. -11/12/93 (bug fix) TkMain.c didn't compile on some systems because of +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". --------------------- Release 3.6, 11/26/93 ------------------------- - -11/10/93 (bug fix) Packer and placer didn't always reposition a window -correctly if it was managed inside a neice or lower descendant (using -"-in" option) and the neice's parent moved. - -11/24/93 (bug fix) Fixed time problem in selection (retrievals could -fail if retriever hasn't received any X events since selection was -made, so that time of retrieval appears to be older than time of -selection). Selection code is now much less picky about times, both -on retrieving and supplying sides. +----------------- Released version 7.3, 11/26/93 ------------------ -12/2/93 (new feature) Changed arrow-head drawing code for canvas -lines to draw a 0-width outline in addition to filling the area: -this produces much nicer, more symmetrical displays. +239. 11/6/93 Modified "lindex", "linsert", "lrange", and "lreplace" +so that "end" can be specified as an index. -12/2/93 (bug fix) When colors ran out, Tk was invoking "tkerror" -when its state was internally inconsistent, which could cause -core dumps in some situations (e.g. if tkerror used the same color -that caused colors to run out). Changed notification to occur -as a when-idle handler. +240. 11/6/93 Modified "append" and "lappend" to allow only two +words total (i.e., nothing to append) without generating an error. -12/3/93 (bug fix) During a global grab, Tk wasn't including PointerMotion -in the list of grabbed events, so pointer motion couldn't be tracked -outside the grabbing application. - -12/3/93 (bug fix) Canvases didn't handle smoothed lines correctly -when they only contained two points. - -12/3/93 (bug fix) Fixed bug in tkWindow.c where certain kinds of -errors during window creation could cause Destroy events to be generated -for a window that was never completely initialized. - -12/13/93 (bug fix) Fixed bug in tkTextDisp.c that resulted in core -dumps at line 1467 under exmh. The exact situation is that a text -widget was being redisplayed at a time when it had a -yscrollcommand -option but hadn't yet been mapped onto the screen. - -12/17/93 (bug fix) Fixed bug in tkWindow.c whereby new top-level windows -with non-default visuals still inherited border pixmap from parent (root), -which could cause visual clash and X error. - -12/17/93 (bug fix) Fixed bug in tkTextDisp.c that caused round-off -error in the information passed to scroll commands. - -12/18/93 (bug fix) Fixed bug in tkPack.c that caused core dumps in -some situations if a master with siblings packed "-in" it was deleted. - -12/18/93 (bug fix) Added "compat" directory to distribution, since it's -referenced by tkConfig.h on some systems. - -12/18/93 (performance improvement) Improved performance of appending to -a listbox, so that inserting N items doesn't take N**2 time. - -12/20/93 (bug fix) Fixed bug in canvas ovals that caused the fill color -for the oval to stick out past the outline. - -1/2/94 (fixed Xlib bug) Added code to reuse X resource identifiers so -that they won't run out in long running applications. There are three -new library procedures: Tk_FreeXId, Tk_GetPixmap, and Tk_FreePixmap. -Modified all Tk code to use these procedures, so wish applications should -now be able to run forever without running out of identifiers. - -1/10/94 (bug fix) tkCursor wasn't freeing pixmaps used to create -cursors, which caused memory leaks in programs that changed cursors -frequently. - -1/21/94 (bug fix) Fixed bug in scales that caused them to loop -infinitely drawing tick-marks when -from and -to were the same. - -2/2/94 (bug fix) Fixed problem where messages that contained tabs -didn't always compute the correct size, so that text spilled off -the right edge. The fix adds an extra "tabOrigin" parameter to -the internal procedures TkMeasureChars, TkDisplayChars, and -TkUnderlineChars. - -2/4/94 (bug fix) Fixed off-by-one problem in tkBind.c that caused -it to read past the initialized part of dispPtr->modKeyCodes. - -2/7/94 (bug fix) Text widgets didn't handle grabs correctly, such -that the "current" character got stuck if a grab occurred while a -mouse button was down. It would get unstuck until after the -next button press and release. - -2/19/94 (bug fix) Fixed prolog.ps (prolog for Postscript printing from -canvases) so that it correctly prints all of the characters in the -ISO Latin-1 character set. - -2/19/94 (bug fix) Modified tkBind.c to save and restore the interpreter's -result across the execution of binding scripts. Otherwise if an event -triggers in the middle of some other script (e.g. a destroy event during -window creation, because there was an error in the creation command), -the intepreter's result gets lost. - -2/19/94 (bug fix) Fixed bug in dealing with results of sent command -that could cause them to get lost in some situations. - -2/21/94 (bug fix) Don't let user close a dialog window created by -tk_dialog, since this would cause tk_dialog to hang: force the user -to select one of the dialog's buttons. - -2/21/94 (bug fix) Fixed bug in canvas polygons whereby they didn't -correctly handle changes in the number of points (via "coords" -widget command). - -2/23/94 (bug fix) Large bitmaps in canvases didn't print correctly -because they overflowed the 64-KB limit on strings in Postscript. -Changed canvas printing to split up large bitmaps into mutliple -smaller ones for printing. - -2/25/94 (bug fix) The "." window was being set up with -width -and -height options, which interfered with geometry management (any -configuration change on "." causes the window to change size to -200x200, then change back again). - -2/26/94 (bug fix) Fixed several bugs that occurred when a Destroy -event handler for a window deleted the window's parent. - -3/3/94 (new features) Changes to binding mechanism: - - The modifiers for "Alt", "Meta", and "M" are now computed by - examining the modifier map, rather than being hardwired to - M2, M1, and M1. - - When processing events, one script is invoked for each object - in the list passed to Tk_BindEvent, rather than stopping as - soon as a script is invoked for some object. The "break" and - "continue" commands can be used within a script to abort all - scripts for the event or the current one. - *** POTENTIAL INCOMPATIBILITY *** - - Added "bindtags" command so that new binding groups can be - defined for widgets and the evaluation order can be changed. - - When matching events to bindings, extra modifiers are now ignored, - as if "Any" were specified for every event. The "Any" modifier - is still recognized, but it is ignored and is deprecated. - *** POTENTIAL INCOMPATIBILITY *** - - In % sequences that print window identifiers (e.g. %a and %S), print - in hexadecimal rather than decimal, for consistence with "winfo id". - *** POTENTIAL INCOMPATIBILITY *** - - The "bind" command no longer supports the event types CirculateRequest, - ConfigureRequest, MapRequest, or ResizeRequest. These event types - are somewhat dangerous, and they never worked anyway. - -3/13/94 (bug fix) Fixed numerous problems with the "wm iconwindow" command. -It appears that this command never really worked at all, but it should -work OK now. - -3/14/94 (feature changes) Removed several obsolete features: - - Eliminated "enable" and "disable" widget commands for menus. - *** POTENTIAL INCOMPATIBILITY *** - - Eliminated "activate" and "deactivate" widget commands for buttons, - checkbuttons, radiobuttons, and menubuttons. - *** POTENTIAL INCOMPATIBILITY *** - - Removed -geometry option for frames and toplevels: it causes - problems when .Xdefaults files contain entries like - "*geometry: +0+0". Must use -width and -height instead. - *** POTENTIAL INCOMPATIBILITY *** - - Desupported "tkVersion" variable: use "tk_version" instead. - *** POTENTIAL INCOMPATIBILITY *** - -3/16/94 (feature changes) Changes to listboxes: - - Eliminated -geometry option (it causes problems when .Xdefaults - files contain entries like "*geometry: +0+0"). Added -width - and -height options to use instead. - *** POTENTIAL INCOMPATIBILITY *** - -3/21/94 (bug fix) Fixed bug in tkOption.c where the option cache wasn't -properly cleaned up after window deletion; this could cause the wrong -value from the option database to be used under some conditions. - -3/25/94 (new features) Changes to geometry management: - - Added Tk_MaintainGeometry and Tk_UnmaintainGeometry procedures - to solve problems with -in windows. Modified the packer, the - placer, and canvases to use them. - - Changed 2nd argument to Tk_ManageGeometry from Tk_GeometryProc * - to a pointer to a structure with additional information about - the geometry manager, such as name and procedure to call when - slaves are stolen. - *** POTENTIAL INCOMPATIBILITY *** - -3/28/94 (new feature) Overhauled event management: - - Added "cancel" option to the "after" command so that you can - cancel previously-scheduled commands. - - Separated X-specific stuff from generic event management. The - file tkEvent.c can now be used stand-alone without the rest of Tk. - See the manual entry for Tk_EventInit for information on which - procedures are available this way. - - Added Tk_CreateFileHandler2 procedure, which provides a lower-level - and more powerful form of file event handler. - - Fixed bug in Tk_DoOneEvent where an infinite loop could occur if - the TK_FILE_EVENT and TK_DONT_WAIT flags were set simultaneously - (there were bugs with several other combinations too; all should - be fixed now). - -3/28/94 (new feature) Added "fileevent" command, which allows event- -driven I/O in the style of Mark Diekhans' "addinput" command. - -4/11/94 (new feature) Better support for colormaps and visuals: - - Added new -colormap and -visual options to toplevels and frames. - - Added "winfo visualsavailable" command. - - Added "wm colormapwindows" command, plus support for WM_COLORMAP_WINDOWS - to Tk_SetWindowColormap. - - Added new library procedures Tk_GetVisual, Tk_GetColormap, - and Tk_FreeColormap. - -4/11/94 (bug fix) Fixed core dump that used to occur when specifying -an iconwindow ("wm iconwindow") for a toplevel on a different screen -than the main window. - -4/23/94 (new feature) Added support for images, including the following: - - New "image" command for creating images. - - Built-in image type: bitmap. - - New "image" item type in canvases. - - Labels, buttons, checkbuttons, radiobuttons, menubuttons, and - menu entries now support a -image option for displaying images. - - Tk_CreateImageType and Tk_ImageChanged procedures, for defining - new types of images in C. - - Tk_GetImage, Tk_FreeImage, Tk_RedrawImage, and Tk_SizeOfImage - procedures, for using images in widgets. - -5/1/94 (new features) Added new procedures Tk_3DVerticalBevel and -Tk_3DHorizontalBevel. - -5/11/94 (new features) Major overhaul of text widgets: - - Implemented embedded windows and "window" widget command. - - Added new configuration options for tags: -justify, -lmargin1, - -lmargin2, -rmargin, -offset, -spacing1, -spacing2, and -spacing3. - See the "Display styles" widget demo for examples. - - Added new configuration options for texts: -spacing1, -spacing2, - and -spacing3. - - Added "tagList" option to "insert" widget command to control - tags on new text. Made tagged regions so they aren't sticky on - either side: new characters get a tag only if the old chars. on - both sides had it. - *** POTENTIAL INCOMPATIBILITY *** - - Added gravity for marks, and "mark gravity" widget command. - - Added horizontal scrolling, "xview" widget command, -xscrollcommand - option. Changed "scan" widget commands to support horizontal - scrolling. - *** POTENTIAL INCOMPATIBILITY *** - - Added "search" widget command for searching (either exact matches - or regular expressions). - - New widget commands: bbox, dlineinfo, and see. - - Changed implementation of bindings so that Enter and Leave - events are not generated unless the tag has just become present - (or just ceased to be present) on the current character. Also - changed bindings to process separately for each tag, rather than - having high-priority tags override low-priority ones. - - The "end" index now refers to the character after the last newline - rather than the newline itself. You can now tag the final newline - and set a mark after the final newline. - - Deletions of the "sel" tag and the "insert" and "current" marks - are now ignored silently, rather than generating errors. This means - you can do things like "eval .t tag delete [.t tag names]". - -5/19/94 (bug fix) Canvases didn't generate proper Postscript for stippled -text. - -5/20/94 (new feature) Added "bell" command to ring the display's bell. - -5/20/94 (new feature) Incorporated "square" demonstration widget into -tktest application. - -5/20/94 (new features) Changed wish application (tkMain.c): - - wish no longer processes the -help option. - *** POTENTIAL INCOMPATIBILITY *** - - The wish main program is now called Tk_Main; tkAppInit.c has a - "main" procedure that calls Tk_Main. This makes it easier to use - Tk with C++ programs, which need their own main programs, and it - also allows an application to prefilter the argument list before - calling Tk_Main. - *** POTENTIAL INCOMPATIBILITY *** - - The application's class is now the same as its name (except the - first letter is capitalized), instead of "Tk". - *** POTENTIAL INCOMPATIBILITY *** - - The -file keyword is no longer required: the script file name can - be provided as the first argument without being preceded by "-file", - as in tclsh. For backward compatibility the "-file" keyword is - ignored if it is the first argument, but it is deprecated. - -5/26/94 (feature removed) Removed support for "fill" justify mode from -Tk_GetJustify and from the TK_CONFIG_JUSTIFY configuration option. None -of the built-in widgets ever supported this mode anyway. -*** POTENTIAL INCOMPATIBILITY *** +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. -5/27/94 (feature change) Changed Tk to use Tk_PrintDouble everywhere -that it converts reals to strings. This means that floating-point -values will be generated in some cases where integer-like values were -generated before. -*** POTENTIAL INCOMPATIBILITY *** +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). -6/1/94 (feature change) Renamed "pack newinfo" command to "pack info". -The old "pack info" command is no longer available. -*** POTENTIAL INCOMPATIBILITY *** +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). -6/20/94 (feature changes) Overhaul of entry widgets: - - Added "-justify" option. - - Added "-show" option to make entries easier to use for passwords. - - Added "cget" widget command. - - Added "selection range" and "selection present" widget commands. - - Added "anchor" symbolic index. - - Changed "-scrollcommand" option to "-xscrollcommand", "view" - widget command to "xview", for compatibility with other widgets. - *** POTENTIAL INCOMPATIBILITY *** - - Changed sel.last to refer to character just *after* last one - selected, again for compatibility with other widgets. - *** POTENTIAL INCOMPATIBILITY *** - - For "delete" widget command, second index now refers to character - just *after* last one to delete. - *** POTENTIAL INCOMPATIBILITY *** - - Overhauled bindings to be more Motif-compatible and to include - common Emacs bindings for editing. - - Changed -width option: if specified as 0, widget sizes to fit - its current text. - -6/11/94 (new features) Improved Motif compatibility: - - Added "-highlightwidth" and "-highlightcolor" options to all widgets. - -6/27/94 (bug fix) Postscript generation for text items in canvases was -not justifying the text properly when a -width was specified that was -longer than the longest line. - -6/27/94 (bug fix) "winfo exists" used to report a window as existing -if it was in the process of being destroyed (i.e., a destroy handler -is in the middle of execution). Changed to report it as non-existent -under these conditions. -*** POTENTIAL INCOMPATIBILITY *** +244. 2/4/94 Added support for unary plus. -7/11/94 (bug fix) Selections claimed via "selection own" weren't always -being cleared properly when the selection was claimed away. Also fixed -bug where Tk wasn't properly claiming the selection, if there haven't -been any recent X events at the time of the claim. - -7/13/94 (feature changes) Overhaul of scrollbar widgets: - - New widget commands: "activate", "cget", "fraction", and "identify". - - New options: -activebackground, -activerelief, -highlightcolor, - -jump, -highlightthickness, and -troughcolor. What used to be - -background is now -troughcolor, -foreground is now -background, - and -activeforeground is now -activebackground. - *** POTENTIAL INCOMPATIBILITY *** - - Added new syntax for "set" command, "get" result, and generated - commands. Changed other widgets to use the new syntax. - - Moved the bindings out of C and into Tcl scripts, using the new - options and widget commands. Added support for all Motif - bindings, plus jump scrolling and cancelling of slider drags. - -7/16/94 (bug fix) Canvases assumed that the Leave event for one item -didn't modify or delete the next current item; this could cause core -dumps under some conditions. - -7/23/94 (feature change) Modified Tk_BackgroundError so that tkerror -is invoked as an idle handler. If tkerror generates a break exception -then all other queued reports are aborted. - -8/14/94 (bug fix) "cursorOffTime" and "cursorOnTime" were confused in -canvases, resulting in the same time being used for both. - -8/16/94 (bug fix) "tkwait variable" command didn't detect errors in -variable name, such as trying to wait for an entire array. - -9/2/94 (new features) Overhaul of scale widgets: - - Floating-point values are supported now, following Paul Mackerras' - "fscale" widget. Added "-resolution" and "-digits" options. - - Added "-variable" option to link scale to variable, following - Henning Schulzrinne's implementation. - - Added focus highlight (-highlightthickness and -highlightcolor - options). - - Added new widget commands "cget", "coords", "identify", plus - improved "get"; removed wired-in bindings, added complete set - of Motif bindings via Tcl scripts. - - Changed -sliderforeground option to -background, -background to - -troughColor, -activeforeground to -activebackground. - *** POTENTIAL INCOMPATIBILITY *** - - Moved value label from below horizontal scales to above the scale, - for Motif compliance. - -9/9/94 (bug fix) Fixed bug in tkWm.c that caused long delays in "raise" -command under some conditions (window already at the top of the stack). - -9/10/94 (new features) Overhaul of label/button/checkbutton/radiobutton -widgets: - - Added focus highlight (-highlightthickness and -highlightcolor - options). - - Added new widget command "cget". - - Changed -selector option to -selectcolor, and changed its meaning - too: empty no longer means don't draw the indicator; it means - don't use a special color when selected. - *** POTENTIAL INCOMPATIBILITY *** - - Added -indicatoron (controls whether indicator is displayed) and - -selectimage (gives special image to display when selected) options. - - Modified bindings to be more Motif-like, added binding for space - key. - - Changed padding defaults to give widgets correct Motif appearance - by default. Also, changed to ignore padding options when displaying - an image or bitmap. - *** POTENTIAL INCOMPATIBILITY *** - - Can now display text on multiple lines: newlines cause line breaks, - and word wrapping can be requested with -wraplength option. Also - added -justify and -underline options. - - The -value option for radiobuttons can now have an empty string as - its value; it no longer defaults to the name of the widget. - *** POTENTIAL INCOMPATIBILITY *** - -9/13/94 (new features) Modified both canvases and messages to support --highlightthickness and -highlightcolor options plus "cget" widget -command. +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. -9/19/94 (new features) Added Tk_UnsetGrid procedure, modified widgets -to use it. Also changed Tk_SetGrid so that at most one window per -toplevel can have gridding enabled. - -9/23/94 (new features) Major overhaul of listbox widgets: - - Added focus highlight (-highlightthickness and -highlightcolor - options). - - Added new widget command "cget". - - Revised selection commands to support single selections as well - as multiple disjoint selections; syntax of "selection" widget - command has changed to support this. Added new option -selectmode - for specifying which mode to use. Default is single selection; - tk_listboxSingleSelect procedure no longer exists. Selections - now return as items separated by newlines instead of a list whose - elements are the items. - *** POTENTIAL INCOMPATIBILITY *** - - Extended "get" widget command to allow many items to be retrieved - at once. - - Added "bbox" widget command for finding position of an element on - screen. - - Added "activate" command to mark element with traversal focus. - - Extended index mechanism to support new types of indices: - "active", "anchor", "@x,y". - - Added "see" widget command. - - Revised bindings to include all Motif features except for AddMode. - - If -width or -height option is <= 0, the widget requests a size just - large enough to hold all of its text. - -10/6/94 (new features) Overhaul of menubuttons: - - Added focus highlight (-highlightthickness and -highlightcolor - options). - - Added new widget command "cget". - - Added -indicatoron option to display option menu indicator. - - The -menu option must be a child of the menubutton. - *** POTENTIAL INCOMPATIBILITY *** - -10/6/94 (new features) Overhaul of menu widgets: - - Added new widget commands "cget" and "entrycget". - - Changed the implementation of tear-off menus to be more - Motif-like; added -tearoff option for specifying whether - tearoff entry is displayed. - - Changed interpretation of "@y" index: it now returns the - closest entry, rather than "none" if y is outside the menu's - range. - *** POTENTIAL INCOMPATIBILITY *** - - The -menu option for a cascade entry must now be a child of - the menu. - *** POTENTIAL INCOMPATIBILITY *** - - Added "type" widget command, so that you can query the type of - an entry. - - Added -foreground, -activeforeground, -selectcolor, -indicatoron, - -image, and -selectimage options to menu entries. - - Changed "selector" menu option to "selectColor" for Motif compliance. - *** POTENTIAL INCOMPATIBILITY *** - - Added -relief option for menus, just for consistency with other - widgets (it was implicitly "raised" before). - -10/6/94 (feature change) Completely overhauled the bindings for menus -and menubuttons. They now fit better with other Tk 4.0 facilities, -such as the new binding mechanism, and they provide better Motif -compliance (e.g. keyboard traversal of submenus). Also, the bindings -now support option menus, popup menus, and proper Motif tear-off -menus. - -10/6/94 (obsolete features) The procedures tk_menuBar and -tk_bindForTraversal are no longer needed in Tk 4.0. They still exist -for compability, but they do nothing. - -10/6/94 (new procedures) Added "tk_popup" procedure for posting a -popup menu, and "tk_optionMenu" for creating an option menubutton -and its associated menu. - -10/6/94 (change in name) The variable "tk_priv" has been renamed -to "tkPriv" to reflect that fact that it is private to Tk now. -This shouldn't cause any problems, since no-one except Tk should -have been using it before anyway (right?). - -10/6/94 (bug fix) Fixed bug in texts where sometimes the text would -stop tracking mouse motion (the "current" item wouldn't get updated) -because the text widget missed a ButtonRelease event. - -10/20/94 (new features) Overhauled selection code to support multiple -selections (primary, secondary, etc.) and multiple displays: - - Changed "selection" command to support new options such as - "-displayof" and "-selection". Old command formats are still - supported for compatibility, but they are no longer documented - and are deprecated. - - Changed procedures Tk_GetSelection, Tk_CreateSelHandler, and - Tk_ClearSelection to take additional "selection" argument. - *** POTENTIAL INCOMPATIBILITY *** - - Selection targets APPLICATION and WINDOW_NAME have been replaced - by TK_APPLICATION and TK_WINDOW. - *** POTENTIAL INCOMPATIBILITY *** - -10/20/94 (new features) Added support for clipboard: - - New "clipboard" command. - - C procedures Tk_ClipboardClear and Tk_ClipboardAppend. - - Bindings for "cut", "paste", and "copy" for text and entry widgets, - plus "copy" binding for listboxes. - -10/24/94 (bug fix) Button widgets weren't checking for errors when -setting the values of associated variables. - -11/3/94 (bug fix) Fixed bug whereby Tk would hang if "exit" was invoked -from inside a <Destroy> binding. - -11/15/94 (new features) Overhaul of focus mechanism: - - Added support for multiple displays: separate focus windows are - kept for each display. - - Added support for keyboard traversal. - - Changed focus model so Tk keeps track of a focus window for each - top-level window and automatically sets the focus on Enter to the - top-level. Tk no longer synthesizes FocusIn and FocusOut events, - but just uses the standard X mechanisms. There is no "default" - focus window anymore; the focus reverts to top-levels by default. - *** POTENTIAL INCOMPATIBILITY *** - - Changed focus command: eliminated "focus default" and "focus none", - added "-displayof" and "-lastfor" options. An empty string is now - used to signify "no focus" instead of "none". - *** POTENTIAL INCOMPATIBILITY *** - - Added library procedures tk_focusNext, tk_focusPrev, and - tk_focusFollowsMouse. - - Removed obsolete Tk_CreateFocusHandler: must use FocusIn and - FocusOut events now. - *** POTENTIAL INCOMPATIBILITY *** - -11/23/94 (new features) Overhaul of "send" command: - - Added support for multiple displays: -displayof option to "send". - - Added asynchronous sends: -async option to "send". - - Eliminated fixed timeouts on sends: as long as the target - application appears to exist, the send will wait for it. - - Stale entries get removed from the application registry now, - so "winfo interps" should never return non-existent applications. - - Can change the name of an application with "tk appname" command. - This is also the preferred way of querying the application name - now. - - The errorCode and errorInfo variables are now propagated back to - the sender now, so a full stack trace is available. - - Tk checks display security on each send now, instead of just during - initialization, so changes in the security status are seen immediately - by all applications. - - The above changes required changes to the data formats used for - communication between source and target applications, so Tk 4.0 - applications cannot send to, or be sent from, Tk 3.6 applications. - *** POTENTIAL INCOMPATIBILITY *** - - The procedure Tk_RegisterInterp has been replaced with Tk_SetAppName. - *** POTENTIAL INCOMPATIBILITY *** - -12/6/94 (cleanup) Eliminated "interp" argument to Tk_GetColorByValue, -since it is no longer needed. -*** POTENTIAL INCOMPATIBILITY *** +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. -12/7/94 (feature change) Changed the "wm" command so that top-level -windows are now resizable by default. You can no longer specify -empty arguments to "wm maxsize" and "wm minsize". -*** POTENTIAL INCOMPATIBILITY *** +247. 2/19/94 Added new procedure Tcl_DStringGetResult to move result +from interpreter to a dynamic string. -12/8/94 (new feature) Added new "photo" image type using code provided -by Paul Mackerras: currently supports only PPM "P6" format images. +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. -12/14/94 (new features) Canvas modifications: - - Modified the interfaces between generic canvas code and the item - types so that it's easy for people to write new item types outside - of Tk. - - Added support for transparent bitmap items: just specify an - empty string as the background color. - - Changed the "xview" and "yview" commands for canvases to use the - new scrolling syntax. - - Eliminated -scrollincrement option. - *** POTENTIAL INCOMPATIBILITY *** +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". -12/14/94 (bug fix) Fixed bug where the dimensions of canvas arrowheads -scaled during a "scale" widget command, but the scaling was only -temporary and got lost on the next re-configure of the item. The -correct behavior is for the arrowheads not to scale. +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. --------------------- Release 4.0b1, 12/23/94 ------------------------- +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. -12/26/94 (bug fix) Removed obsolete demos from Makefile (color, dialog, -size), fixed "install" target. +252. 3/3/94 Added Tcl_AllowExceptions procedure. -1/3/95 (bug fix) Fixed all procedure calls to explicitly cast arguments: -implicit conversions from prototypes don't work when compiling under -non-ANSI compilers. Tk is now clean under gcc -Wconversion. +253. 3/13/94 Fixed bug in Tcl_FormatCmd that could cause "format" +to mis-behave on 64-bit Big-Endian machines. -1/4/95 (bug fix) Used "screenX" without ever setting it in DisplayText -in tkCanvText.c: caused tabs in canvas text items to get messed up. +254. 3/13/94 Changed to use vfork instead of fork on systems where +vfork exists. -1/4/95 (bug fix) Canvases forgot to register the built-in types if -Tk_CreateItemType was called before a canvas widget was created. +255. 3/23/94 Fixed bug in expressions where ?: didn't associate +right-to-left as they should. -1/4/95 (bug fixes) Fixed glitches in various text bindings: - - Up used to do nothing if the cursor was at 2.0. - - Right used to make the cursor invisible if it was just before - the final newline of the text. - - Control-t didn't conform to Emacs; made it conform to GNU Emacs. - - Deleted Control-x binding, since it doesn't conform to anything and - is confusing for Emacs users. +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. -1/4/95 (bug fixes) Changed Control-t for entries just as for texts (see -above) an deleted Control-x for entries (see above). +257. 4/3/94 Added "subst" command. -1/4/95 (bug fix) The packer didn't map slaves unless the master was mapped; -this could cause slaves to get "lost" so that they weren't mapped until the -master resized. - -1/5/95 (bug fix) Scrollbars weren't executing the proper code the first time -the mouse entered the widget; this caused problems if tk_strictMotif was -set. - -1/6/95 (bug fix) Fixed label/button/checkbutton/radiobutton/menubutton -widgets to allow arbitrary screen distances when specifying -width and --height for an image or bitmap (the manual pages already documented this -but the code didn't implement it). - -1/6/95 (new feature) Added very primitive support for input methods, -as suggested by Martin Forssen. This should be enough for European -character sets (Compose key) but it isn't near enough for Asian -character sets. +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 *** -1/8/95 (bug fix) Fixed problem in canvas "xview" and "yview" commands -where divide-by-zero errors could sometimes occur. +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. -1/8/95 (bug fix) New event handler didn't properly handle files for -which both TK_READABLE and TK_WRITABLE were specified. +260. 6/13/94 Added "wordstart" and "wordend" options to "string" command. -1/11/95 (bug fix) Fixed bug with text selections: was returning count -too high for data, causing bogus garbage to appear when selection was -copied. +261. 6/27/94 Fixed bug in expressions where they didn't properly cancel +the evaluation of math functions in &&, ||, and ?:. --------------------- Release 4.0b2, 1/12/95 ------------------------- +262. 7/11/94 Incorrect boolean values, like "ogle", weren't being +handled properly. -1/27/95 (feature removal) Removed %D substitution from binding scripts: -wasn't portable, shouldn't be used anyway. -*** POTENTIAL INCOMPATIBILITY *** +263. 7/15/94 Added Tcl_RegExpCompile, Tcl_RegExpExec, and Tcl_RegExpRange, +which provide lower-level access to regular expression pattern matching. -1/27/95 (new features) Added -displayof options to the commands -"winfo atom", "winfo atomname", "winfo containing", "winfo interps", -and "winfo pathname". +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. -1/27/95 (new feature) Added "idle" option to "after" command to run -scripts as idle handlers. +265. 8/4/94 Fixed bug with linked variables where they didn't behave +correctly when accessed via upvars. -1/28/95 (new feature) Modified placer to make -x and -relx additive -if you specify both. Same for -y and -rely, -width and -relwidth, -and -height and -relheight. This makes it easy to make request such -as "make .a 2 pixels larger than .b". -*** POTENTIAL INCOMPATIBILITY *** +266. 8/17/94 Fixed bug in Tcl_EvalFile where it didn't clear interp->result. -1/28/95 (new feature) Improved auto-grab mechanism in canvases (which -prevents current item from changing while a button is down): changed -to report Enter and Leave events for the current item while a button -is down. However, as before, no Enter events are reported for other -items until the button goes up. +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. -1/28/95 (new feature) Bitmap images are now transparent if the -background -is specified as an empty string (-maskdata and -maskfile are ignored in -this case). This is also the default. +268. 9/9/94 Modified "expr" command to generate errors for integer +overflow (includes addition, subtraction, negation, multiplication, +division). -1/28/95 (bug fix) Tk didn't support manufacturer- or site-specific keysyms -such as SunAudioMute. Modified tkBind.c so that it uses XStringToKeysym -in addition to its own hash table, so that all keysyms are now available. +269. 9/23/94 Modified "regsub" to return a count of the number of +matches and replacements, rather than 0/1. -1/30/95 (feature change) Modified "clipboard append" so that it reclaims -the clipboard selection if it had been previously lost, rather than just -generating an error. This handles certain race conditions more cleanly, -and also allows the use of programs like "xclipboard". +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. -1/30/95 (new feature) Added -xscrollincrement and -yscrollincrement -options to canvases. +280. 10/6/94 Modified Tcl_SetVar2 so that read traces on variables get +called during append operations. -1/31/95 (bug fix) Geometry management was broken if a particular geometry -manager claimed a slave away from itself. +281. 10/20/94 Fixed bug in "read" command where reading from stdin +required two control-D's to stop the reading. -1/31/95 (bug fix) Fixed bug in tkVisual.c where a visual with fewer bits -than requested was being selected in preference to one with just the right -number of bits. +282. 11/3/94 Changed "expr" command to use longs for division just like +all other expr operators; it previously used ints for division. -1/31/95 (bug fix) Texts weren't redisplaying the padding region properly -after changes in -padx or -pady. +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. -1/31/95 (new features) More text improvements: - - Extended "insert" widget command for texts to allow multiple - text-tagList pairs in the same command. - - Added -nocase option to "search" widget command. - - Added -overstrike option to tags. - - Added tab stops, via -tabs option for widget and for tags. +----------------- Released version 7.4b1, 12/23/94 ------------------ -2/10/95 (bug fix) Modified all widgets to allow renaming of widget -commands. Deleting a widget command will delete the widget. +284. 12/26/94 Fixed "install" target in Makefile (couldn't always +find install program). -2/11/95 (new feature) Added -highlightbackground option to all widgets. +285. 12/26/94 Added strcncasecmp procedure to compat directory. -2/14/95 (new feature) Added "insert" widget command for menus. +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. -2/15/95 (new feature) Modified text display code (for all widgets) to -display well-known control characters like newline and backspace as -\n or \b instead of \xa. +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. -2/15/95 (bug fix) Modified bitmap and photo image managers to delete -the image command when the image is deleted. Also modified them to -allow renaming of the image command, and to delete the image if the -image command is deleted. +----------------- Released version 7.4b2, 1/12/95 ------------------ -2/15/95 (bug fix) Fixed text widgets to allow horizontal scrolling -even if wrapping was enabled, if a line isn't entirely visible due to -a large character or embedded window. +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. -2/16/95 (feature change) Added "postcascade" widget command to menus, -changed "invoke" and "activate" not to post or unpost submenus. Also -fixed bug in redisplay that tended to leave bits of garbage on menu -when submenu unposted. +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 *** -2/16/95 (feature removal) Removed "snap back" behavior (slider -snaps back to old position if you move the mouse outside the widet -before releasing the button) from scrollbars and scales. +290. 2/14/95 Added code to Tcl_GetInt and Tcl_GetDouble to check for +overflows when reading in numbers. -2/16/95 (bug fix) The last line of a listbox wasn't being displayed if -it was only partially visible. - -2/16/95 (new features) Added support for "-resolution 0" (no rounding -of values) to scale widgets, plus smarter computation of how many digits -to display. - -2/17/95 (bug fix) Fixed bug in text bindings for things like Shift-Left: -didn't properly set the anchor position. - -2/20/95 (bug fix) Changed management of COLORMAP_WINDOWS property to -add the toplevel implicitly to the end of the list if it wasn't already -on the list somewhere. Without this, some window managers implicitly -put it at the front of the list, so that colormaps in internal windows -are never used. - -2/20/95 (bug fix) Changed to use separate command procedures for -button, checkbutton, label, and radiobutton commands. This allows the -class commands to be renamed without breaking their behavior. - -2/20/95 (removed feature) The "bind" command no longer supports -"Keymap" events; they never worked anyway. - -2/20/95 (bug fix) The text "search" widget command looped infinitely -when searching an empty text. - -2/20/95 (bug fix) Canvases weren't redrawing their borders after -configuration changes. - -2/20/95 (upgrade) Changed to use autoconf version 2.2. - -2/21/95 (bug fix) Fixed several bug fixes in menu bindings that occur -when menus have no entries. - -2/21/95 (bug fix) Fixed bug in geometry management that caused windows -packed -in siblings to not always be mapped and unmapped properly -(particularly when the toplevel got unmapped and mapped). - -2/22/95 (bug fix) Fixed resource leak problem in tkTextDisp.c that -caused embedded windows not to be unmapped when off-screen. - -2/23/95 (bug fix) "After cancel" dumped core when the script for an -after event cancelled itself. - -2/24/95 (bug fix) Text and entry widgets weren't properly ignoring -Alt-, Control-, and Meta- keystrokes, so a widget-specific binding -for one of these resulted in the character also being inserted. - -2/24/95 (bug fix) Several widgets accidentally performed unsigned -division on negative numbers, thereby losing the sign bit. This -mostly affected the display of images and bitmaps in buttons, -menubuttons, and messages. - -2/24/95 (feature reversal) Restored old behavior of %A so that it -returns non-printing characters as well as printing ones now. -*** POTENTIAL INCOMPATIBILITY with Tk 4.0b2, but not with Tk 3.6 *** - -2/24/95 (bug fix) Duplicate "leave" events could occur for canvas -items under some conditions, due to recursive calls to PickCurrentItem. -Added code to detect and skip the nested calls. - -2/24/95 (bug fix) Fixed bug where an error could occur during the first -keystroke in an application if its binding invoked "break". - -2/25/95 (new feature) Modified syntax of "search" widget command for -texts. The -nowrap switch and the "variable" final argument are no -longer supported. Instead, there is a -count switch to replace -the final argument; if the final argument is specified, it is now -a stopping index for the search. The features of -nowrap can be -achieved now with the stopping index. -*** POTENTIAL INCOMPATIBILITY with Tk 4.0b2, but not with Tk 3.6 *** - -2/27/95 (bug fix) Fixed problem that appears to prevent keyboard -input for working under IRIX: tkBind.c was ignoring XmbLookupString -calls that returned a status of XLookupBoth. - -2/27/95 (new feature) Added Tk_GetItemTypes procedure to return -information about available canvas item types. - -2/27/95 (feature change) Changed Makefile to always use install-sh -for installations: there's just too much variation among "install" -system programs, which makes installation flakey. - -2/27/95 (bug fix) Fixed bug in tkSend.c that caused core dumps if -the app's main window was destroyed by a destroy handler on a -child. - -3/5/95 (feature change) Change separator character used in "bind +..." -bindings from semi-colon to newline (permits bindings that are -comments, for what that's worth). - -3/7/95 (bug fix/feature change) Overhauled focus code, both in C -and in Tcl: - - Tk won't move the X focus in response to the "focus" command - unless either the application already has the focus or the - -force switch is specified. - - Tk no longer sets the X focus to anything other than top-levels; - it synthesizes events for FocusIn and FocusOut to children. - - A window no longer has to be viewable when focussed to; Tk will - set the X focus later, when the window becomes viewable. - - Added -takefocus option to all widgets. - - Rewrote tk_focusPrev and tk_focusNext to use the -takefocus option. - These procedures no longer set the focus; they just return the - next window in focus order. - *** POTENTIAL INCOMPATIBILITY with Tk 4.0b2, but not with Tk 3.6 *** - - Eliminated tk_focusContinue. - *** POTENTIAL INCOMPATIBILITY with Tk 4.0b2, but not with Tk 3.6 *** - -3/8/95 (new feature, bug fix) Added support for tk_strictMotif variable -in C: Tk_StrictMotif library procedure. Modified buttons, menubuttons, -menus to use it. This fixes the problem with menus not supporting -tk_strictMotif properly in Tk4.0b1 and b2. - -3/16/95 (feature overhaul) Overhauled color management: - - Changed Tk so it never denies a color request because a colormap - filled up. Instead, it allocates the closest available color. - - Eliminated "color model" mechanism. The "tk colormodel" command - is gone, as are the procedures Tk_GetColorModel and Tk_SetColorModel. - *** POTENTIAL INCOMPATIBILITY *** - - Changed 3D border implementation to allocate colors for shadows - lazily, so they're never allocated if they're never used. Also - added new feature whereby stippling is used for borders when - the colormap has run out of entries. Changed arguments to many - of Tk_3D C procedures to take a Tk_Window as argument instead of - a (Display *). This is needed to do lazy color allocation. - *** POTENTIAL INCOMPATIBILITY *** - - Eliminated colormap argument to Tk_GetColor, Tk_GetColorByValue, - and Tk_Get3DBorder. - *** POTENTIAL INCOMPATIBILITY *** - -3/16/95 (feature change) Event bindings created from Tcl will now ignore -Enter, Leave, FocusIn, and FocusOut events with detail NotifyInferior. -This is done in anticipation of mega-widgets, so that the user of a -mega-widget can create Enter/Leave bindings on the mega-widget without -seeing spurious events as the mouse moves among the windows in the -mega-widget. -*** POTENTIAL INCOMPATIBILITY *** +291. 2/18/95 Changed "array set" to stop after first error, rather than +continuing after error. -3/17/95 (feature change) Changed C interfaces throughout Tk to use ints -instead of unsigneds: the unsigneds turn out to cause subtle problems -with arithmetic in some places, and using ints everywhere is just -simpler. -*** POTENTIAL INCOMPATIBILITY *** +292. 2/20/95 Upgraded to use autoconf version 2.2. -3/23/95 (bug fix) Selections longer than 4000 bytes were being -truncated to 4000 bytes. +293. 2/20/95 Fixed core dump that could occur in "scan" command if a +close bracket was omitted. --------------------- Release 4.0b3, 3/24/95 ------------------------- +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. -3/25/95 (bug fix) Modified Tk's selection mechanism to prevent core -dumps in other applications during retrievals of large selections -(this is actually a bug in the other apps, but I've patched Tk to -keep it from getting triggered). - -3/25/95 (bug fix) Fixed bug where X window for "." wasn't being -deleted. - -3/27/95 (bug fix) Fixed many bugs associated with having more than -one application in a single process. - -3/28/95 (bug fix) The "search" widget command for texts didn't -return the correct index and count if there were embedded widgets -on the same line as the returned range but before the end of -the range. - -3/28/95 (bug fix) Changed pasting via button 2 in text and entries -so that it inserts at the pointer location, not the location of -the insertion cursor. - -3/28/95 (bug fix) Fixed several bugs related to <Destroy> bindings -that delete ancestors in the window hierarchy. Also eliminated -extraneous calls to XDestroyWindow, which speeds up window deletion -by about 3x. - -3/28/95 (bug fix) Several widgets (buttons, menubuttons, menus) didn't -properly handle image deletions that occurred while the widget was -being deleted (caused core dumps). - -3/29/95 (bug fix) When retrieving long selections from text widgets, -parts of lines were getting duplicated in the selection information. - -4/1/95 (bug fix) Fixed bug that caused infinite loop in horizontal -scales with 0 range. - -4/1/95 (bug fix) Fixed problem with -command option for scrollbars and --takefocus option that caused commands to be evaluated in the wrong -context. - -4/1/95 (bug fix) Fixed problem with option database that caused it to -sometimes use the wrong option (wasn't flushing the database properly -after a change in a window's class). +3/29/95 (bug fix) Fixed bug where the auto-loading mechanism wasn't +protecting the values of the errorCode and errorInfo variables. -4/1/95 (bug fix) If a line in a text widget just barely fit in the window, -Tk was allocating a second screen line just for the newline character. +3/29/95 (new feature) Added optional pattern argument to "parray" procedure. -4/1/95 (new feature) When backspacing in an entry widget, when you reach -the left edge of the widget, the insertion cursor gets recentered. +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. -4/1/95 (new features) Added "winfo pointerx" and "winfo pointery" commands -to fetch the current pointer position. +4/6/95 (new feature) Added "pattern" option to "array names" command. -4/6/95 (bug fix) If the last line of a text widget was only partially -visible, it was counted as visible for purposes of the scrollbar. Now -it is treated as if it were off-screen for scrolling purposes. +4/18/95 (bug fix) Fixed bug in parser where it didn't allow backslash-newline +immediately after an argument in braces or quotes. -4/6/95 (new feature) Modified "bell" command to reset screen saver as well. +4/19/95 (new feature) Added tcl_library variable, which application can +set to override default library directory. -4/6/95 (feature change) Modified menu scanning (where menus pull down -as you drag across their menubuttons) so it only works among menus -in the same toplevel; it used to work for any menubuttons in the -application. - -4/6/95 (bug fix) Canvas text items weren't allowing real numbers in -"@x,y" notation for specifying indices. - -4/7/95 (bug fix) Menus didn't display correctly when -activeborderwidth -was large. - -4/7/95 (bug fix) Changed "clipboard append" command to support -- option -and to always treat the last argument as data, even if it starts with -"-". - -4/17/95 (new feature) Added -wrap option to text tags. - -4/18/95 (bug fix) Listboxes and texts weren't updating their grid information -when -width or -height changed. - -4/18/95 (bug fix) "Down" didn't work right in text widgets if the last -line was only partially visible in the window. - -4/19/95 (bug fix) Listboxes didn't handle partially visible last lines -right: couldn't scroll it into full visibility, for example. - -4/20/95 (bug fix) If a toplevel was positioned with a command like -"wm geometry . -0-0", the window didn't reposition itself to maintain -that geometry after a size change. - -4/21/95 (feature change) Changed order of binding tags so widget bindings -fire before class bindings. New order is: widget, class, toplevel, all. -*** POTENTIAL INCOMPATIBILITY with Tk 4.0b3, but not with Tk 3.6 *** - -4/23/95 (new feature) Added "winfo colormapfull" command. - -4/23/95 (new feature) Buttons and radiobuttons and checkbuttons now -treat Return the same as Space, unless tk_strictMotif is set. - -4/23/95 (bug fix) Modified menu tear-off procedure to duplicate the -binding tags and bindings of the original in the copy. - -4/25/95 (bug fix and feature change) Modified mechanism for choosing -"best" visual to fix a bug where depth wasn't really getting highest -priority in all situations. - -4/28/95 (bug fix) Failed text searches starting at "end" could result -in an infinite loop in Tk. - -4/30/95 (new feature) Added "wm resizable" command to enable and -disable interactive resizing. - -4/30/95 (new feature) Added "window names" widget command to texts: -returns a list of all embedded windows. - -5/2/95 (feature change) Changed text searches so that forward searches -start at the given index, rather than the character just after the -given index. -*** POTENTIAL INCOMPATIBILITY with Tk 4.0b3, but not with Tk 3.6 *** - -5/4/95 (bug fix) Default bit gravity for windows was wrong (it was -ForgetGravity) causing unnecessary flashing when windows were resized. - -5/4/95 (feature change) Modified Tk_DoOneEvent so that it doesn't -sleep if there's nothing that will wake it up again (e.g. no file -or timer handlers). Returns 0 immediately. +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. -5/5/95 (configuration change) Changed to use BSDgettimeofday instead -of gettimeofday on systems like IRIX where BSDgettimeofday is -available. This avoids compilation problems due to the different -interface to gettimeofday provided by IRIX. +4/30/95 (new feature) Added -nobackslashes, -nocommands, and -novariables +switches to "subst" command. -5/5/95 (feature change) Changed binding mechanism so that all bindings -are created immediately at initialization time, rather than waiting -until the first FocusIn or Enter event for a class. +5/4/95 (new feature) Added TCL_EVAL_GLOBAL flag to Tcl_RecordAndEval. -5/6/95 (feature change) Changed default text for labels, buttons, -checkbuttons, radiobuttons, menubuttons, and messages from " " to -"". +5/5/95 (bug fix) Format command would overrun memory when printing +integers with very large precision, as in "format %.1000d 0". -5/6/95 (bug fix) If the application was destroyed in the middle of -an "update" command, Tk would dump core. +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. -5/6/95 (bug fix) Change "wm iconwindow" command to disable button -presses for the icon window. This is needed so that the window -manager can get those events (X only allows button presses to go -to one client for a given window). +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. -5/9/95 (new feature) When specifying visuals, can now use "best" -with a depth, e.g. "-visual {best 8}" to get the best 8-bit visual. +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. -5/18/95 (bug fix) Fixed bug with -spacing* options for text widget: -screen distances weren't allowed, only integers. +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). -5/20/95 (bug fix) Eliminated memory leaks in tkTextDisp.c and elsewhere. - -5/22/95 (color change) Changed the Tk color palette to a gray scheme. -Also added a library procedure tk_setPalette that makes it easy to -change colors on the fly, and a procedure tk_bisque that restores the -previous light brown scheme. - -5/28/95 (bug fix) Modified canvases so that the -width and -height -options refer to the space inside the borders, not the total widget -space. Also changed "xview" and "yview" commands and scroll-increment -rounding to use the pixel just inside the borders, rather than (0,0). - -5/28/95 (bug fix) Several widgets (e.g. entries, buttons, and menus) -didn't properly handle unsets of variables they were tracing, if the -variables were reference through upvars in procedures. - -6/4/95 (bug fix) The placer wasn't rounding window widths right when -both -relx and -relwidth were specified (or -rely and -relheight) so -that rounding errors accumulated. - -6/4/95 (feature improvement) Change parsing of text indices to handle -weird mark and tag names better (e.g. any string ending with ".first" -will now be parsed as a tag name, even if it contains embedded spaces, -etc.). +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. -6/4/95 (feature change) If a font defines glyphs for control characters, -they are now displayed, instead of translating the character to a -backslash sequence (however, tabs and newlines are still treated -specially; glyphs are not displayed for these characters). +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. -6/4/95 (bug fix) Modify the implementation of "raise" and "lower" for -toplevels so that it now works under olwm and olvwm. It didn't use to -work, and the problem is really in the window manager, but Tk now -patches around it. However, only "total" raises and lowers work: -raising and lowering relative to a sibling still don't work under -olvwm and olwm. +----------------- Released version 7.4b4, 6/16/95 ------------------ -6/4/95 (feature change) Modified tab code in texts so that a tab always -occupies at least as much space as a space character. +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. -6/4/95 (bug fix) The "%t" substitution wasn't being made properly in -Enter and Leave event bindings. +6/21/95 (feature removal) Removed overflow checks for integer arithmetic: +they just cause too much trouble (e.g. for random number generators). -6/7/95 (new feature) Added support for GIF images. Unfortunately it's -a bit fragile: certain kinds of badly formed images can cause core -dumps; I don't know enough about the GIF reader (taken from giftoppm) -to figure this out. +6/28/95 (new features) Added tcl_patchLevel and tcl_version variables, +for consistency with Tk. -6/7/95 (bug fix and feature change) Fixed PPM image reader to be more -flexible about header formats, and added support for PGM images. +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! +]" -6/7/95 (feature change) Added -outlinestipple option to canvas arc -items, changed "-style arc" to use -outline as the color instead of --fill (the old approach was pretty quirky). -*** POTENTIAL INCOMPATIBILITY *** +6/29/95 (message change) Changed the error message for ECHILD slightly +to provide a hint about why the problem is occurring. -6/8/95 (feature change) Modified interface to Tk_Main to pass in the -address of the application-specific initialization procedure. -Tcl_AppInit is no longer hardwired into Tk_Main. This is needed -in order to make Tcl a shared library. +----------------- Released version 7.4, 7/1/95 ------------------ -6/8/95 (feature change) Modified Makefile so that the installed versions -of wish and libtk.a have version number in them (e.g. wish4.0 and -libtk4.0.a) and the library directory name also has an embedded version -number (e.g., /usr/local/lib/tk4.0). This should make it easier for -Tk 4.0 to coexist with earlier versions. +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. -6/9/95 (new feature) Added -outline and -width options to canvas polygon -items. +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. -6/9/95 (feature changed) Renamed -decimate in photo widget to -subsample -(decimate wasn't technically correct). -*** POTENTIAL INCOMPATIBILITY with Tk 4.0b3, but not with Tk 3.6 *** +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. --------------------- Release 4.0b4, 6/16/95 ------------------------- +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"). -6/19/95 (bug fix) Colors weren't being rounded correctly in canvas -Postscript generation: caused "white" to appear slightly gray when -the display of the canvas used only 8 bits per color. +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. -6/20/95 (bug fix) "bbox" widget command for texts didn't return -proper width for tabs. +7/27/95 (bug fix) The version of strtod in fixstrtod.c didn't properly +handle the case where endPtr == NULL. -6/20/95 (bug fix) Scrollbars didn't always work right for texts: -couldn't scroll all the way to the bottom of the text in a single -drag of the slider. +----------------- Released patch 7.4p1, 7/29/95 ----------------------- -6/20/95 (new feature) Added "delta" widget command for scrollbars -(needed for above bug fix). +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) -6/23/95 (bug fix) Listboxes weren't properly redisplaying their -borders when the were configured to a smaller size. +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) -6/23/95 (new feature) Added "winfo server" command. +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) -6/23/95 (bug fix) If a menu was posted, couldn't switch to another -menu with an Alt- key. +8/23/95 (new features) Added "info sharedlibextension" and +"info nameofexecutable" commands, plus Tcl_FindExtension procedure. (JO) -6/24/95 (new feature) Added "winfo pointerxy" command. +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) -6/25/95 (bug fix) Tk_ParseArgv referenced beyond the end of 0-length -option names. +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) -6/25/95 (bug fix) Fixed problem in tkOption.c where "cachedWindow" -could get garbage in it if the main window's class was changed by -calling Tk_SetClass. +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) -6/25/95 (bug fix) Fixed two bugs in menus, one where errors in -variable traces weren't propagated correctly and one where "invoke" -was invoked at the wrong stack level, with the result that variable -traces didn't have access to the right variables. +8/28/95 (bug fix) Exec wasn't handling bad user names properly, as +in "exec ~bogus_user/foo". (JO) -6/27/95 (bug fix) tk3d.c wasn't using all the right information -when deciding whether or not to stipple borders, so it stippled -borders even on 16-bit true-color displays. +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) -6/28/95 (bug fix) Page up and down operations in texts could cause -insertion cursor to drift to the right. Changed tkTextScrollPages -to use upper-left corner of current character, rather than center -of character. +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) -6/28/95 (bug fix) Changed text widget so that you can't put the -insertion cursor after the last newline in the text. +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) -6/28/95 (bug fix) Bitmap images didn't allow ~'s in file names. +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 *** -6/28/95 (bug fix) Fixed problem that could cause core dumps in the -text widget when dealing with embedded windows (there were problems -if the act of redisplaying caused the window layout to change, which -can happen with embedded windows). +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 *** -6/28/95 (bug fix) Texts didn't handle indices with double negatives, -such as ".t mark set insert {insert + -20 chars}". +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) -6/28/95 (bug fix) Fixed problem where focus didn't always revert to -its prior window after a dialog box was dismissed. +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. -6/28/95 (bug fix) Fixed problem with "search" widget command returning -incorrect length on some backwards regexp searches. +----------------- Released patch 7.4p2, 9/15/95 ----------------------- -6/28/95 (bug fix) Successive "wm iconbitmap . {}" commands could cause -a core dump. +----------------- Released 7.5a1, 9/15/95 ----------------------- -6/29/95 (new feature) Added -elementborderwidth option for scrollbars -so the -borderwidth can be set to 0 without flattening the arrows and -slider. +9/22/95 (bug fix) Changed auto_mkindex to create tclIndex files that +handle directories whose paths might contain spaces. (RJ) --------------------- Release 4.0, 7/1/95 ------------------------- +9/27/95 (bug fix) The "format" command didn't check for huge or negative +width specifiers, which could cause core dumps. (JO) -7/18/95 (bug fix) %t in event bindings didn't work properly for some -events (e.g. PropertyNotify). +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) -7/18/95 (bug fix) Changed "exec wish" lines in demo scripts to -"exec wish4.0" to avoid version conflicts. +9/28/95 (bug fix) Changed makefile.bc to eliminate a false dependency +for tcl1675.dll on the Borland run time library. (SS) -7/18/95 (bug fix) Fixed round-off errors in scrolling for texts, -canvases, listboxes, and entries. The error could cause the view -to shift up in a command like "$w yview moveto [lindex [$w yview] 0]". +9/28/95 (bug fix) Fixed tcl75.dll so it looks for tcl1675.dll instead +of tcl16.dll. (SS) -7/19/95 (bug fix) Canvases weren't always redrawing borders correctly -when they became unobscured. There were also some problems with -improper refresh after size changes. +9/28/95 (bug fix) Tcl was not correctly detecting the difference +between Win32s and Windows '95. (SS) -7/19/95 (bug fix) Fixed bug in text index processing that causes -tests textIndex-11.1 and textIndex12.1 to fail on some platforms. +9/28/95 (bug fix) "exec" was not passing environment changes to child +processes under Windows. (SS) -7/19/95 (bug fix) Fixed bug where 2-second delays were ocurring during -"raise" and "lower" commands for toplevel windows under some window -managers (such as fvwm). +9/28/95 (bug fix) Changed Tcl to ensure that open files are not passed +to child processes under Windows. (SS) -7/20/95 (bug fix) Text searches were misbehaving when there were embedded -windows on the starting line of the search. The most common symptom is -that Tk would fail to find a match at the starting position for the -search. +9/28/95 (bug fix) Fixed Windows '95 and NT versions of exec so it can +handle both console and windows apps. (SS) -7/22/95 (bug fix) Fixed core dump that could occur in menus if a checkbutton -entry's -variable option referred to an array (or couldn't be read -by the menu C code for some other reason). +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) -7/22/95 (bug fix) Text widgets didn't update their scrollbars when -changes were made to information that was off-screen. +9/28/95 (bug fix) Eliminated source dependency on the Win32s Universal +Thunk header file, since it is not bundled with VC++. (SS) -7/25/95 (bug fix) Fixed core-dump in tkListbox.c that used to happen -in the command ".l bbox end" if the listbox was empty. +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) -7/25/95 (bug fix) Page-up and page-down bindings for listboxes didn't -move active element to remain on the screen. +9/28/95 (bug fix) Added support for "info nameofexecutable" and "info +sharedlibextension" to the Windows version. (SS) -7/25/95 (bug fix) Patched around H-P compiler problem that results in -core-dumps in tkImgPhoto.c during image handling. +9/28/95 (bug fix) Changed tclsh to correctly parse command line +arguments so that backslashes are preserved under Windows. (SS) -7/25/95 (bug fix) Fixed bug in tkImgPhoto.c that caused core dumps -(during Tk self-tests and other image uses) on AIX and other machines -where "schar" in tkImgPhoto.c was being defined as "short" instead of -"char". +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) -7/26/95 (bug fix) The PPM image reader couldn't handle maximum intensity -values other than 255. +9/29/95 (new feature) Changed to install "configInfo" file in same +directory as library scripts. It didn't used to get installed. (JO) -7/26/95 (bug fix) Canvases didn't redraw their borders when the relief -changed from raised to flat. +9/29/95 (bug fix) Tcl was not converting Win32 errors into POSIX +errors under some circumstances. (SS) -7/27/95 (bug fix) Canvases didn't set the scrolling values correctly -when no scroll region was specified. +10/2/95 (bug fix) Safe interpreters no longer get initialized with +a call to Tcl_Init(). (JL) -7/28/95 (bug fix) Modified menu and tk_dialog scripts to restore any -old grab that might have been in effect before a menu or dialog was -posted. +10/1/95 (new feature) Added "tcl_platform" global variable to provide +environment information such as the instruction set and operating +system. (JO) ------------------ Released patch 4.0p1, 7/29/95 ---------------------- +10/1/95 (bug fix) "exec" command wasn't always generating the +"child process exited abnormally" message when it should have. (JO) -8/4/95 (bug fix) Calls to toupper and tolower weren't using the UCHAR -macro, so they didn't always work in non-U.S. locales. (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) -8/14/95 (new feature) Added -tearoffcommand option for menus. +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) -8/16/95 (bug fix) Canvases didn't generate proper Enter and Leave -events if the Leave handler for an item reconfigured the canvas in -a way that made the old current item the new current item again. (JO) +10/2/95 (bug fix) File sharing was causing refcounts to reach 0 +prematurely for stdin, stdout and stderr, under some circumstances. (JL) -8/21/95 (bug fix/feature change) When -takefocus was a script, Tk -was allowing window viewability to override it. Changed so that -viewability is now ignored when -takefocus is a script. (JO) +10/2/95 (platform support) Added support for Visual C++ compiler on +Windows, Windows '95 and Windows NT, code donated by Gordon Chaffee. (JL) -8/21/95 (bug fixes) Fixed memory leaks in tkSend.c, tkSelect.c, and -tkUnixWm.c (JO). +10/3/95 (bug fix) Tcl now frees any libraries that it loads before it +exits. (SS) -8/21/95 (bug fix) Text widgets didn't handle commands like -".t search -backwards foo end 1.0" properly: never found foo. (JO) +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) -8/23/95 (new feature) Added Makefile and configure.in support for -dynamic loading. (JO) +----------------- Released 7.5a2, 10/6/95 ----------------------- -8/25/95 (bug fix) The "frame" and "toplevel" commands couldn't safely -be renamed, due to a kludgy way that they shared a single command -procedure. Split into separate procedures. (JO) +10/10/95 (bug fix) "file dirnam /." was returning ":" on UNIX instead +of "/". (JO) -8/25/95 (bug fix) Fixed bug in libary/menu.tcl that caused "grab -window not visible" errors for popup menus (and perhaps elsewhere?). (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 *** -8/25/95 (bug fix / new feature) The "gray25" bitmap was really only -12.5% on, not 25%. Added new "gray12" bitmap that is the same as the -old "gray25". "Gray25" is still supported for compatibility, but its -use is deprecated. (JO) +----------------- Released patch 7.4p3, 11/28/95 ----------------------- -8/25/95 (bug fix) Scrollbar bindings didn't properly handle case where -B2 is clicked while B1 is already down. (JO) +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 *** -8/26/95 (bug fix) Menus were ignoring -activebackground if tk_strictMotif -was set, but not -activeforeground. Changed to ignore both. (JO) +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) -8/26/95 (bug fix) Scales and scrollbars didn't properly handle a --repeatdelay value of 0 (they shouldn't auto-repeat in this case). (JO) +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) -8/28/95 (bug fix) Tcl errors were occurring for tkPriv(oldGrab) when -clicking on a disabled option menu. (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) -8/28/95 (bug fix) Changed event-handling code to use FD_SETSIZE instead -of OPEN_MAX, since OPEN_MAX is incorrect on some systems (e.g., IRIX). (JO) +12/20/95 (new feature) Added Tcl_WaitForFile procedure. (JO) -8/28/95 (bug fix) Fixed bug in photo images that caused garbling of -image data in the "put" and "copy" commands if the source data had -only one scan line but had a width less than the width of the target -image. (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) -8/29/95 (bug fix) Tk used to refuse to post menus if they had no -entries. This made it impossible for a menu to fill itself the first -time it is posted. Changed to allow menus with no entries to be -posted. (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) -8/30/95 (bug fix) If there was extra space at the bottom of a menu, -it wasn't being redisplayed properly. +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) -8/30/95 (new feature) Added -transient option to menus. +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) -8/30/95 (new features) Added proper button 2 support to both scrollbars -and scales (it sets the slider position from the mouse position). (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 *** -8/30/95 (bug fix) Fixed potential core dump that could occur in -photo images (ReadPPMFileHeader could overflow buffer under some bad -inputs, such as certain GIF images). (JO) +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) -8/30/95 (bug fix) Errors of the form `syntax error in expression "!"' -could occasionally happen in tkScaleDrag. (JO) +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) -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) +1/19/96 (new feature) Implemented on-close handlers for channels; added +the C APIs Tcl_CreateCloseHandler and Tcl_DeleteCloseHandler. (JL) -9/1/95 (new feature) Added "after info" command. Also added checks -so that one interpreter can't cancel another's "after" events. (JO) +1/19/96 (new feature) Implemented portable error reporting mechanism; added +the C APIs Tcl_SetErrno and Tcl_GetErrno. (JL) -9/8/95 (bug fix) Fixed bug that could cause memory corruption and core -dumps if a "fileevent" handler was deleted while the handler was -active. (JO) +1/24/96 (bug fix) Unknown command processing properly invokes external +commands under Windows NT and Windows '95 now. (SS) -9/11/95 Reorganized Tk 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. (SS) - -9/11/95 (new feature) Added new "notifier" mechanism to allow multiple -implementations of the mechanisms for finding out about events. This -change was necessary to support Mac and PC platforms, but it may also -allow other goodies such as combining Xt and Tk widgets in a single -application. See the new manual entry Notifier.3 for details. (SS) - -9/11/95 (feature change) Changed interface to Tk_RestrictProc so that -(a) it takes a clientData argument instead of display and arg, and -(b) it returns a value that can ask for the event to be discarded as well -as deferred or processed. (SS) -*** POTENTIAL INCOMPATIBILITY *** +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 $HOME with /.Xdefaults, resulting in a // in the middle of the +file name. Under Windows '95, this is incorrectly interpreted as a UNC +path. They delays came from the network timeouts needed to determine that +the file name was invalid. Tcl_TranslateFileName now suppresses duplicate +slashes that aren't at the beginning of the file name. (SS) + +1/25/96 (bug fix) Changed exec and open to create children so they are +attached to the application's console if it exists. (SS) -9/11/95 (new feature) Added TK_WINDOW_EVENTS #define, which is equivalent -to TK_X_EVENTS but is now preferred, since it applies to all platforms. (SS) +1/31/96 (bug fix) Fixed command line parsing to handle embedded +spaces under Windows. (SS) -9/11/95 (feature change) Can't export variables anymore because this doesn't -work under Windows DLLs. Eliminated tk_NumMainWindows variable and replaced -with procedure Tk_GetNumMainWindows. (SS) -*** POTENTIAL INCOMPATIBILITY *** +----------------- Released 7.5b1, 2/1/96 ----------------------- -9/11/95 (new feature) Added procedure Tk_PreserveColormap to increment -the reference count on colormaps. Used in photo widgets. (SS) +2/7/96 (bug fix) Fixed off by one error in argument parsing code under +Windows. (SS) ------------------ Released patch 4.0p2, 9/15/95 ---------------------- +2/7/96 (bug fix) Fixed bugs in VC++ makefile that improperly +initialized the tcl75.dll. Fixed bugs in Borland makefile that caused +build failures under Windows NT. (SS) ------------------ Released 4.1a1, 9/15/95 ---------------------- +2/9/96 (bug fix) Fixed deadlock problem in AUTO end of line translation +mode which would cause a socket server with several concurrent clients +writing in CRLF mode to hang. (JL) -9/22/95 (renamed files) Changed the names of the bitmap images in the -$tk_library/demos/images directory to use the .bmap file extension. (RJ) +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 *** -9/22/95 (bug fix) Fixed bug where text widgets could occasionally -display the insertion cursor both at the end of one line and the -beginning of the next. (JO) +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) -9/25/95 (bug fix) Fixed bug that could cause core dumps when an -application uses multiple screens and a binding destroys the main -window (bind code was using MainInfo structure after it had been -freed). (JO) +2/9/96 (new feature) Implemented asynchronous connect for sockets. (JL) -9/25/95 (bug fix) Text widgets sometimes scrolled backwards on -occasion if you dragged down past the bottom of the scrollbar. (JO) +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) -9/25/95 (bug fix) Fixed bug in menus where a cascaded submenu posted -from a torn-off menu could be left posted if mouse was pulled off the -end of the cascade and released. (JO) +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) -9/25/95 (new feature) Added "--" switch to wish, so that you can -pass arguments like -n through to a script without having wish -interpret them. (JO) +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) -9/25/95 (bug fix) Fixed core dump that could occur for radiobuttons -and selectbuttons if -selectcolor was an empty string. (JO) +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) -9/26/95 (bug fix) Entries didn't used to notice if a trace procedure -on the -textvariable overrode a new value set by the entry. This -could cause the variable to get out of sync with the contents of the -entry. (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) -9/26/95 (new feature) Added -sliderrelief option to scales, changed -default bindings to change the slider's relief to sunken while it's -being dragged with the mouse. (JO) +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) -9/26/95 (bug fix) TkColor.c wasn't computing colormap size correctly; -could result in X Protocol error for QueryColors when colormaps run -out of colors. (JO) +2/13/96 (bug fix) Fixed problems with DLL initialization under Visual +C++ that left the C run time library uninitialized. (SS) -9/26/95 (bug fix) Wish couldn't handle script files with spaces in -their names. (JO) +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) -9/27/95 (cosmetic clean-up) Removed extraneous spaces to make error -messages consistent: ": should be" is now ": should be". (JO) +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) -9/27/95 (feature change) Modified tk_dialog so that it uses the -option database for the -wraplength option on the message. This -allows the option to be overridden by the caller. (JO) +2/13/96 (bug fix) Fixed bug with seek leaving EOF and BLOCKING set. (JL) -9/28/95 (bug fix) Wish incorrectly parsed the command line under -Windows, causing backslashes to be substituted. (SS) +2/14/96 (bug fix) Fixed reentrancy problem in fileevent handling +and made it more robust in the face of errors. (JL) -9/28/95 (bug fix) Wish now sources wishrc.tcl instead of .wishrc. (SS) +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) -9/28/95 (bug fix) Tk_DoOneEvent returned 0 under some circumstances -when it was possible to find more work to do. For example, if a -signal interrupted select(), but no event handlers were triggered, it -would return 0 even though it could still detect events by reentering -select(). (SS) +2/15/96 (new feature) Added "binary" end of line translation mode, which is +a synonym of "lf" mode. (JL) -9/29/95 (bug fix) "winfo interps" caused a crash under Windows. (SS) +2/15/96 (bug fix) Fixed reentrancy problem in fileevent handling vs +deletion of channel event handlers. (JL) -10/1/95 (feature change) Eliminated Tk_NotifyIdle interface in favor of -Tk_IdlePending. (SS) +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) -10/1/95 (bug fix) Turned motion event collapsing into an idle handler -so it will be easier to move the event loop into Tcl. (SS) +2/17/96 (bug fix) "info complete" didn't properly handle comments +in nested commands. (JO) -10/1/95 (bug fix) Fixed several problems with negative coordinates -in canvases. One example: dragging a canvas rectangle with a wide -border and fractional coordinates could leave junk on the screen -if the rectangle was in negative coordinate space. (JO) +2/21/96 (bug fix) "exec" under Windows NT/95 did not properly handle +very long command lines (>200 chars). (SS) -10/2/95 (bug fix) Tk was improperly handling Enter/Leave events -during a button grab. (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) -10/2/95 (new feature) Added support for the Macintosh do script -('dosc') event. Available only on the Macintosh. (RJ) +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) -10/4/95 (new feature) Added support for compiling with VC++. -Resulting binaries work under Win32s through NT. +----------------- Released 7.5b2, 2/23/96 ----------------------- ------------------ Released 4.1a2, 10/6/95 ---------------------- +2/23/96 (bug fix) TCL_VARARGS macro in tcl.h wasn't defined properly +when compiling with C++. (JO) -10/10/95 (new feature) Macintosh Tk now supports the complete set -of X cursors that Unix Tk supports. (RJ) +2/24/96 (bug fix) Removed dependencies on Makefile in the UNIX Makefile: +this caused problems on some platforms (like Linux?). (JO) -10/11/95 (bug fix) Tk now supports all of the X11 cursors under -Windows. (SS) +2/24/96 (bug fix) Fixed configuration bug that made Tcl not compile +correctly on Linux machines with neither -ldl or -ldld. (JO) -10/11/95 (bug fix) The "wm resizable" command was missing from the -Windows version of Tk. (SS) +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) -10/12/95 (bug fix) Macintosh Tk had problems with clipping toplevel -windows that children of any frame other than another toplevel. (RJ) +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 *** -10/13/95 (bug fix) Eliminated dependency on MKS toolkit for generating -the tk.def file from Borland object files. (SS) - -10/16/95 (bug fix) Fixed clipping and update problems relating to -the raising and lowering of overlapping windows on Mac. (RJ) - -10/30/95 (bug fix) When focus-follows-mode (invoked via tk_focusFollowsMouse), -was focussing on windows even in situations where keyboard traversal would -skip the window. Changed to use the tkFocusOK procedure so that the -criteria for focussing are the same in both modes. (JO) - -11/2/95 (bug fix) Changed listbox bindings to ignore double-clicks. -This avoids errors that used to occur if a user defined a binding -for double-click that deleted the listbox. (JO) - -11/3/95 (feature change) Moved most of the Tk event loop to Tcl. Many -Tk_ names have become Tcl names now: - -TK_READABLE => TCL_READABLE -TK_WRITABLE => TCL_WRITABLE -TK_EXCEPTION => TCL_EXCEPTION -TK_DONT_WAIT => TCL_DONT_WAIT -TK_WINDOW_EVENTS => TCL_WINDOW_EVENTS -TK_FILE_EVENTS => TCL_FILE_EVENTS -TK_TIMER_EVENTS => TCL_TIMER_EVENTS -TK_IDLE_EVENTS => TCL_IDLE_EVENTS -TK_ALL_EVENTS => TCL_ALL_EVENTS -Tk_IdleProc => Tcl_IdleProc -Tk_FileProc => Tcl_FileProc -Tk_TimerProc => Tcl_TimerProc -Tk_TimerToken => Tcl_TimerToken -Tk_BackgroundError => Tcl_BackgroundError -Tk_CancelIdleCall => Tcl_CancelIdleCall -Tk_CreateFileHandler => Tcl_CreateFileHandler -Tk_CreateTimerHandler =>Tcl_CreateTimerHandler -Tk_DeleteFileHandler => Tcl_DeleteFileHandler -Tk_DeleteTimerHandler =>Tk_DeleteTimerHandler -Tk_DoOneEvent => Tcl_DoOneEvent -Tk_DoWhenIdle => Tcl_DoWhenIdle -Tk_Sleep => Tcl_Sleep -tkerror => bgerror - -Other than the name changes, the functions are the same. In addition, -there are #defines in tk.h so that the old Tk names will still work. -tkerror and bgerror are specially hacked as synonyms, so it should be -safe to use either one. You should switch to the new Tcl names ASAP, -though, since the old Tk names will eventually be desupported. (JO) - -11/7/95 (features removed) As part of moving the event loop to Tcl, -the following procedures were deleted: - - Tk_EventInit (the presence of the event loop in Tcl should - make this unneccessary). - - Tk_CreatFileHandler2 (you can get the same effect by using event - sources in Tcl, but you have to modify your code to use the new - Tcl APIs). - - All of the stuff in the manual entries Notifer.3 and QueueEvent.3; - this has changed because the notifier got reworked when it was - moved to Tcl. -*** POTENTIAL INCOMPATIBILITY *** +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 *** -11/7/95 (feature change) Changed to use exit handler to cleanup windows -in Tk, so Tk no longer needs to have a private copy of the "exit" command. -(JO) +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) -11/7/95 (bug fix) If wish was invoked with a command-line geometry and -a script file (e.g. "wish foo.tcl -geometry 30x20"), and if one of -the windows created by the script used the -setgrid option, then the -width and height from the command line were lost. (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) -11/8/95 (bug fix) The "see" command didn't work quite right for texts: -if the window was small and you try to "see" a line just offscreen, -Tk centered the line (actually, mis-centered it) when it should have -aligned it at the top or bottom. (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) -11/9/95 (bug fix) The "send" command crashed if you tried to send to -a different display with "-displayof". (JO) +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) -11/9/95 (bug fix) The Symbol font didn't print right in Postscript -output, because of changes made to re-encode fonts to get proper -ISO Latin1 behavior. Changed the code not to re-encode the Symbol -font. (JO) +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 *** -11/13/95 (bug fix) Fixed Makefile.in and configure.in for UNIX so that -configure can be run from a clean directory separate from the Tcl source -tree, and compilations can be performed there. (JO) +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) -11/17/95 (bug fix) If a window was gridded, Tk still computed the -default maximum dimensions in pixel units, which resulted in windows -that could grow much larger than the screen. (JO) +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) -11/17/95 (bug fix) If a menus entries were all disabled, posting -the menu and typing Up or Down caused an infinite loop, locking -up the screen (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) -11/19/95 (bug fix) The focus wasn't being restored properly after a -menu selection in a cascaded menu. (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) -11/19/95 (bug fix) Menubutton's didn't stipple display their images -differently when disabled. Change to have the same behavior as buttons: -the image is stippled over in the background color when the menubutton -is disabled. (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) -11/21/95 (bug fix) Changes in display attributes such as font could -cause core dumps in the text widget under some circumstances involving -line wrapping. (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 *** -11/22/95 (bug fix/new feature) Changed both the placer and the packer -to ensure that slaves are unmapped whenever the master is unmapped. -This saves time that slaves might otherwise spend trying to redisplay -themselves when they're unmapped. (JO) +3/6/96 (changed feature) The library function auto_mkindex will now +default to using the pattern "*.tcl" if no pattern is given. (RJ) -11/22/95 (bug fix) Space and return keys didn't work for menus if -they were posted via Alt-x keystrokes. (JO) +3/6/96 (bug fix) The socket channel code for the Macintosh has been +rewritten to use native MacTcp. (RJ) -11/24/95 (bug fix) tk_dialog procedure had binding for <Return> that -always activated default binding, even if input focus was in some -other binding. Removed this feature, since existing focus support -will already "do the right thing". (JO) +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) -11/24/95 (bug fix) Both canvases and texts could dump core if a binding -(such as ButtonRelease on an internal item) deleted the widget. (JO) +3/7/96 (bug fix) Tcl did close not the file descriptors associated +with "stdout", etc. when the corresponding channels were closed. (SS) -11/24/95 (feature change) Replaced "configInfo" file with tkConfig.sh, -which is more complete and uses slightly different names. Also -arranged for tkConfig.sh to be installed in the platform-specific -library directory. (JO) - -11/24/95 (bug fix) It was possible for a slave to be placed or packed --in itself, with unpleasant consequences. It is now an error for the -slave to be its own master for geometry management. (JO) - -11/25/95 (bug fix) The -command option of scales was sometimes being -invoked spuriously (e.g. when the mouse moved in the scale without a -button down). This was because the scale wasn't rounding properly -when setting the scale value from its associated variable. (JO) - ------------------ Released patch 4.0p3, 11/28/95 ---------------------- - -12/18/95 (feature change) Moved Tk_Preserve, Tk_Release, and -Tk_EventuallyFree to Tcl, renamed to Tcl_Preserve etc. Added #defines -to tk.h so that the old names still work. (JO) - -12/23/95 (bug fix) If a single process had > 1 Tk application, Tk -didn't guarantee that the application names were unique, which could -cause all sorts of confusion with "send". (JO) - -12/23/95 (feature change) Eliminated Tk_CreateMainWindow and moved -all of its functionality to Tk_Init. All that you need to do now -to get Tk in an application is to call Tk_Init. Improved Tk_Init -so that -colormap and -visual command-line arguments are now passed -through to TkCreateFrame. Tk_Main is much simpler now, since a lot -of its functionality has moved to Tk_Init. (JO) -*** POTENTIAL INCOMPATIBILITY *** +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) -12/23/95 (new feature) Added support for Tcl_StaticPackage so -that Tk can now be loaded into slave interpreters with the "load" -command to create new applications. (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) -12/23/95 (new features) Added support for -colormap and -visual command- -line options for wish. (JO) +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 *** -1/4/95 (bug fix) Fixed keyboard code to properly handle alt-key -sequences for international keyboards and menu-accelerators. (SS) +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 *** -1/5/96 (bug fix) Scrollbar code sometimes generated errors on accesses -to tkPriv(relief) during control-clicks. (JO) +3/7/96 (feature change) stdin, stdout and stderr can now be put into +nonblocking mode. (JL) -1/9/96 (new feature) added the "grid" command to provide a table based -geometry manager. (SU) +3/8/96 (feature change) Eliminated dependence on the registry for +finding the Tcl library files. (SS) -1/12/96 (performance optimization) Changed the way tag information is kept -in the text's Btree so the cost of adding and removing tag ranges is no longer -proportional to the number of unique tags in the text. In the old system -the cost of adding N unique tags was O(N-squared). The new implementation is -optimized for tags that only cover a small amount of text, measuring from -their earliest tag range to the end of their last range. In the best case the -cost of adding a tag range is unrelated to the number of unique tags, so the -cost of adding N tags is only O(N). In the worst case, where all tags -cover all the text, the cost is still O(N-squared) to add N such tags. -Deleting tags still has an O(N) cost (so deleting N tags is O(N-squared), -but it is now a factor of 2 faster than the old system. (BW) +----------------- Released 7.5b3, 3/8/96 ----------------------- -1/12/96 (new feature) added the text "dump" operation that returns information -about all elements in a text widget: text, tags, marks, and windows. (BW) +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) -1/12/96 (new feature) added the text "mark next" and "mark previous" operations -to search forward and backwards for the next (previous) mark in the text. (BW) +3/13/96 (bug fix) Eliminated use of the "linger" option from the Windows +socket implementation. (JL) -1/12/96 (new feature) added the text "tag prevrange" operation to search -backwards for the current or previous range of a tag. (BW) +3/13/96 (new feature) Added -peername and -sockname options for fconfigure +for socket channels. Code contributed by John Haxby of HP. (JL) -1/16/96 (new feature) Added support for relative widget placement on -the "grid" command. (SU) +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) -1/17/96 (new feature) Modified the Makefile/configure setup to support -compiling Tk as a shared library. Use the --enable-shared option to -the "configure" script. (JO) +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) ------------------ Released 4.1b1, 1/26/96 ----------------------- +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 *** -2/2/96 (bug fix) Frames were getting a default size of 200x200, whereas -there should be no default. (JO) +3/14/96 (bug fix) "tclsh bogus_file_name" didn't print an error message. (JO) -2/2/96 (bug fix) Argc wasn't getting reset properly after Tk removed -the arguments it understood from those on the command line. (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) -2/6/96 (bug fix) Fixed off by one error in argument parsing code under -Windows. (SS) +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) -2/6/96 (bug fix) "wm transient" now works under Windows. The resulting -toplevel is created with a modal dialog box frame and will not appear -in the taskbar under Windows '95. (SS) +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) -2/9/96 (bug fix) Changed Makefile.in to use -L and -l for Tcl and Tk -libraries so that shared libraries are more likely to be found correctly -on more platforms. (JO) +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) -2/14/96 (feature change) Eliminated tk_CanvasTagsOption variable because -it can't be exported safely across DLL boundaries. Instead, exported -Tk_CanvasTagsParseProc and Tk_CanvasTagsPrintProc procedures for -use by canvas type managers in creating their own custom options. (JO) -*** POTENTIAL INCOMPATIBILITY *** +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) -2/14/96 (bug fix) "winfo pointerxy" when applied to a non-toplevel window -crashed wish. (SS) +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) -2/14/96 (bug fix) "tkwait visibility" would hang under Windows. (SS) +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) -2/14/96 (bug fix) Cursors were not being updated until an enter event. -In cases where the cursor left the toplevel and reentered before Tk -noticed, the cursor would get "stuck" until the next enter event. -Similarly, if the cursor attribute of a window was updated while the -mouse was in the window, the cursor would not change until the next -time the mouse entered the window. (SS) +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) -2/15/96 (bug fix) If a top-level was resizable in one direction -(e.g. "wm resizable . 0 1"), once the user resized it any changes -in the internally requested size (by the widgets) were ignored, -even for the non-resizable dimension. Fixed to handle the two -dimensions totally independently, so the widget's requests are -honored as long as that dimension hasn't been set by the user. (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) -2/17/96 (bug fix) If a text widget had very long lines (e.g. more than -32K pixels), integer overflow could occur, resulting in parts of the -line not being visible. (JO) +8/9/96 (bug fix) Tcl_UpdateLinkedVar generated an error if the variable +being updated was read-only. (JO) -2/20/96 (feature change) Changed the -minsize option of grid to take -screen units instead of pixels. (SU) +8/14/96 (bug fix) The macintosh now supports synchronous socket +connections. Other minor bugs were also fixed. (RJ) -2/20/96 (bug fix) grid row and column weights are compared against -MINWEIGHT (0.001) instead of 0.0 to guard against divide by zero errors -during weight normalization. (SU) +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) -2/20/96 (bug fix) Menu commands were not being invoked sometimes. -There was a race condition that caused events to be processed while a -menu was being unposted. (SS) +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 *** ------------------ Released 4.1b2, 2/23/96 ----------------------- +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 *** -2/23/96 (bug fix) Alt-keys invoked in torn-off and popped up menus -caused menus to be posted in the parent toplevel. (JO) +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) -2/23/96 (bug fix) Canvases weren't always updating their scrollbars -when they should. (JO) +10/11/96 (bug fix) Under Windows, the pid command returned the process +handle instead of the process id. (SS) -2/23/96 (bug fix) Fixed core dump that could occur if a WM_DELETE_PROTOCOL -handler generated an error. (JO) +----------------- Released 7.6, 10/16/96 ----------------------- -2/24/96 (bug fix) Removed dependencies on Makefile in the UNIX Makefile: -this caused problems on some platforms (like Linux?). (JO) +10/29/96 (bug fix) Under Windows, sockets would consume 100% CPU time after +the first accept(), due to a typo. (JL) -2/24/96 (feature change) Changed text and entry widgets so that they -set the insertion cursor before inserting during a button-2 click. -Also made optional bindings check for tk_strictMotif at the time of -the event, rather than at the time the bindings are created. (JO) +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) -2/24/96 (bug fix) Tk tended to crash with an X error when unsetting -an icon window (e.g. "wm iconwindow . {}"). (JO) +11/7/96 (bug fix) Auto-exec didn't work on file names that contained +spaces. (JO) -2/25/96 (bug fix) Wasn't removing windows from the WM_COLORMAP_WINDOWS -property when they were deleted. (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) -3/1/96 (new feature) Added new "bbox" widget command for entries. -Also modified mouse bindings for entries and texts so that the -mouse position rounds to the nearest inter-character gap, rather -than the left edge of the character under the mouse. This provides -more natural selection behavior. (JO) +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) -3/1/96 (bug fix) Fixed core dump that could occur in image code if an -image was deleted while in use in a widet, then re-used in another -widget while "deleted". (JO) +11/12/96 (bug fix) Do not blocking waiting for processes at the end of a +pipe during exit cleanup. (JL) -3/1/96 (bug fix) Calling wish with a single argument caused a crash -under Windows due to an off-by-one error in the argument parsing code. (SS) +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) -3/1/96 (bug fix) Palette management was broken and resulted in -incorrect palette realization and refresh behavior. Also, images were -being drawn incorrectly if they were attached to widgets that had a -private colormap. (SS) +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) -3/2/96 (bug fix) It was possible to press the mouse button over an -option menu, drag to a pulldown menu, and have the pulldown menu -popup in place of the option menu. Fixed this so that option menus -are isolated from each other and from pulldowns. (JO) +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) -3/2/96 (bug fix) Fixed yet another bug that caused long delays when -raising toplevel windows. (JO) +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) -3/2/96 (bug fix) Fixed bug in canvases where zero-sized rectangles -and ovals didn't always redisplay right (could leave trailing -garbage on screen when moved). (JO) +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) -3/2/96 (bug fix) Entry widgets reset their insertion cursor, selection, -and view whenever the text variable changed, plus whenever a "configure" -widget command was invoked and there was a text variable for the -widget. Fixed to preserve this information as much as possible. (JO) +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) -3/5/96 (new feature) Added version suffix to shared library names so that -Tk will compile under NetBSD and FreeBSD (I hope). (JO) +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) -3/6/96 (bug fix) Changed the way certain configure & motion events are -reported. This fixes several bugs in menus & "winfo rootx". (RJ) +1/21/97 (configuration fix) Made it possible to override TCL_PACKAGE_PATH +during make. Previously it was only set during autoconf process. -3/7/96 (bug fix) Fixed tag remove bug that showed up when draging out a -selection. If you had dragged left, then tried to drag back right, the -left edge of the selection wasn't being updated because the tag remove -wasn't doing anything. (BW) +1/29/97 (bug fix) Fixed some problems with the clock command that +impacted how dates were scaned after the year 2000. (RJ) -3/7/96 (bug fix) Fixed the boundary conditions of tag prevrange. The second -index argument wasn't effecting in stopping the search if it fell within -a range. The second index has to come at or before the start of a range -for the range to be found by tag prevrange. (BW) +----------------- Released 7.6p2, 1/31/97 ----------------------- -3/7/96 (bug fix) "puts" to stdout or stderr when running from a script -caused wish41.exe to exit silently. Now the output is silently -discarded without generating an error. (SS) +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) -3/7/96 (bug fix) Fixed bug where wish was treating empty lines in the input -as end of input, if the input came from stdin. This would cause it to -complain about missing closing braces etc. (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) ------------------ Released 4.1b3, 3/8/96 ----------------------- +---------------------------------------------------------- +Changes for Tcl 7.6 go above this line. +Changes for Tcl 7.7 go below this line. +---------------------------------------------------------- -3/9/96 (bug fix) Fixed bug in text.tcl that could cause errors in text -widgets of the form 'can't use non-numeric string as operand of "-"'. (JO) +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) -3/12/96 (feature improvement) Modified startup script to look in several -different places for the Tcl library directory. This should allow tk -to find the libraries under all but the weirdest conditions, even without -the TK_LIBRARY environment variable being set. (JO) +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) -3/14/96 (bug fix) "wish bogus_file_name" didn't print an error message. (JO) +---------------------------------------------------------- +Changes for Tcl 7.7 go above this line. +Changes for Tcl 8.0 go below this line. +---------------------------------------------------------- -3/14/96 (bug fix) Button-2 wasn't claiming the focus during paste -operations. (JO) +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 *** -3/14/96 (bug fix) "tkwait visibility" use to hang forever if its window -was deleted. Now it detects this condition and returns an error. (JO) +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 *** -3/16/96 (bug fix) Changed configuration stuff to get dynamic loading and -shared libraries working under AIX. (JO) +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 *** -3/16/96 (bug fix) Fixed core dumps that could occur when a slave interpreter -was deleted in the middle of executin bindings. (JO) +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) -3/18/96 (new feature) Added support for Activate/Deactivate events. -Currently, these new X events will generated only on the Macintosh. (RJ/CS) +----------------- Released 8.0a2, 1/24/97 ----------------------- -3/21/96 (bug fix) The "tag prevrange" command would fail to return the current -range if it began at 1.0 and the starting point of the search was within -the range. (BW) +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 *** -3/21/96 (configuration improvement) Changed configure script so it -doesn't use version numbers (as in -ltk4.1 and libtk4.1.so) under -SunOS 4.1, where they don't work anyway. (JO) +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 *** -3/22/96 (bug fix) Made Tk more robust against interpreter deletion. Now it -should be safe to delete an interpreter with a Tk application inside it, -without first deleting the Tk application. (JL) +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 *** -3/26/96 (bug fix) Tk now returns results from a "send" to an interpreter -in which the Tk application is destroyed, if the interpreter continues -computing after the Tk application is destroyed. Previously any results -computed after '.' was destroyed in the target interpreter were discarded -by the "send". (JL) +4/23/97 (removed feature) The modal timeout interface has been +removed (Tcl_CreateModalTimeout/Tcl_DeleteModalTimeout) (SS) +*** POTENTIAL INCOMPATIBILITY *** -3/26/96 (new feature) Tk now provides a static Tktest package which is -present only in test versions of Tk; this allows the testing commands to -be loaded into new interpreters besides the main one. (JL) +4/23/97 (feature change) Channel drivers are now required to correctly +implement blocking behavior when they are in blocking mode. (SS) +*** POTENTIAL INCOMPATIBILITY *** -3/28/96 (bug fix) Changed the tk_dialog procedure *not* to make the -dialog a transient for its parent. The old behavior meant that the -dialog did not get posted if the parent was iconified. (JO) +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) -4/5/96 (bug fix) Tk would occasionally crash when destroying toplevels -under Windows. (SS) +----------------- Released 8.0b1, 5/27/97 ----------------------- -4/5/96 (bug fix) Fonts were not being properly deallocated, causing -GDI resources to be consumed and never released under Windows. (SS) +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) -4/11/96 (bug fix) Toplevel windows with no specified geometry were -always appearing in the upper left corner of the screen under -Windows. (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 *** -4/11/96 (bug fix) "wm minsize" did not properly report the minimum -size imposed by the Windows window manager. (SS) +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 *** -4/13/96 (bug fix) Text widgets could dump core in some cases where -text was inserted on the top visible line. (JO) +----------------- Released 8.0b2, 6/30/97 ----------------------- -4/16/96 (bug fix) Changed menu code to ignore errors that occur when -restoring a grab: the old grab window might not be visible anymore. (JO) +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 $b == 2]". (BL) + +8/11/97 (bug fix) The catch command would sometimes crash if a variable name +was given and the bytecode evaluation stack was grown when executing the +argument script. (BL) + +8/12/97 (feature change) Reinstated the variable tcl_precision to control +the number of digits used when floating-point values are converted to +strings, with default of 12 digits. However, had to make tcl_precision +shared among all interpreters (except that safe interpreters can't +modify it). This makes the Tcl 8.0 behavior almost identical to 7.6 +except that the default precision is 12 instead of 6. (JO) +*** POTENTIAL INCOMPATIBILITY *** ------------------ Released 4.1, 4/21/96 ----------------------- +----------------- Released 8.0, 8/18/97 ----------------------- -5/1/96 (bug fix) "option readfile" did not handle files with CRLF -line termination. (SS) +8/19/97 (bug fix) Minimal fix for glob -nocomplain bugs: +"glob -nocomplain unreadableDir/*" was generating an anonymous +error. More in depth fixes will come with 8.1. (DL). + +8/20/97 (bug fix) Removed check for FLT_MIN in binary command so +underflow conditions are handled by the compiler automatic +conversions. (SS) + +8/20/97 (bug fixes) Fixed several compilation-related bugs: + - Array cmd wasn't detecting arrays that, while compiled, do not yet + exist (e.g., are marked undefined since they haven't been assigned + to yet). + - The GetToken procedure in tclCompExpr.c wasn't recognizing properly + whether an integer token was invalid. For example, "0x$" 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). -5/1/96 (bug fix) Changed to install tkConfig.sh under "make install-binaries", -not "make install-libraries". (JO) +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) -5/7/96 (bug fix) Moved initScript in tkUnixInit.c to writable memory to -avoid potential core dumps. (JO) +8/25/97 (bug fix) Fixed array access bug in IllegalExprOperandType +procedure in tclExecute.c: it was not properly supporting the || and && +operators. (BL) -5/7/96 (bug fix) Changed tk_dialog back so that the dialog box is a -transient window again. This is needed to make sure that the dialog -box doesn't get obscured. Also changed it to return -1 if the dialog -window is deleted before the user presses a button. (JO) +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) -5/16/96 (bug fix) Fixed bug that caused core-dumps if a text widget -with -setgrid 1 was deleted by removing its command. (JO) +----------------- Released 8.0p1, 11/7/97 ----------------------- -5/16/96 (bug fix) Fixed bug that caused Tk initialization to use improperly -initialized variables left over from previous invocation of Tk_Init on -another interpreter. (JL) +11/19/97 (bug fix) Fixed bug in linsert where it sometimes accidently +cleared out a shared argument list object. (BL). -5/16/96 (new feature) Implemented application embedding on Windows -platforms (only Tk inside another application, not the other way yet). (JL) +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) -5/16/96 (new feature) Added C API Tk_SafeInit that adds Tk to a safe -interpreter. (JL) +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. -5/16/96 (bug fix) Fixed bug that caused Tk initialization to use improperly -initialized variables left over from previous invocation of Tk_Init on -another interpreter. (JL) +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) -5/16/96 (new feature) Implemented application embedding on Windows -platforms (only Tk inside another application, not the other way yet). (JL) +----------------- Released 8.0p2, 11/25/97 ----------------------- -5/16/96 (new feature) Added C API Tk_SafeInit that adds Tk to a safe -interpreter. (JL) +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) -5/22/96 (bug fix) Listboxes weren't properly ignoring double clicks on -button 1. (JO) +---- Shipped as part of the plugin2.0b5 as 8.0p2Plugin1, Dec 8th 97 ---- -6/12/96 (bug fix) Focus was automatically placed on new toplevels. -This caused the titlebar to flash during menubar traversal. (SS) +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) -6/12/96 (bug fix) Iconification of a window with a specified geometry -by using the minimize button would leave the window in an inconsistent -state. When the window was deiconified using "wm deiconify", the -window would continue to display as an icon with the deiconified -geometry. (SS) +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 *** -6/12/96 (bug fix) Fixed a resource leak where the text widget was not -freeing all of the TkRegions it created. This fix affects all -platforms, but is particularly important for Win32s. (SS) +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) -6/21/96 (configuration change) Added --enable-gcc switch to configure -script to make Tk just like Tcl. Now Tk will not use gcc unless you -request it explicitly. (JO) +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) -7/18/96 (bug fix) Changed "configure" script to add an extra -R switch -(or whatever is appropriate to the platform) if the X library is in a -nonstandard place. This guarantees that the shared library can be -found at runtime without having to set the LD_LIBRARY_PATH variable. (JO) +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) -7/19/96 (bug fix) Fixed bug in tkImgGIF.c that cause core dumps if a -GIF file contained multiple images. (JO) +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) -7/20/96 (bug fix) Deadlock could occur if a recursive series of send -operations involved multiple displays. (JO) +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) -7/23/96 (bug fix) Fixed a resource leak where deallocated XIDs were -taking up memory on Windows and Macintosh platforms. (SS) +----------------- Released 8.0.4, 11/19/98 ------------------------- -7/30/96 (bug fix) A core dump could occur if a <Destroy> handler for -a window tried to create a child in the half-dead window.

(RJ) ------------------ Released patch 4.1p1, 8/2/96 ----------------------- +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) -4/30/96 (new feature) Added support for named virtual events. New "event" -command to define/destroy named virtual events and to programmatically -send both real and virtual events to Tk. (CS) +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) -8/6/96 (bug fix) Entry widgets were invoking scrollbar update functions -too often. (JO) +1/11/98 (bug fix) On HP, "info sharedlibextension" was returning +empty string on static apps. It now always returns ".sl". (RJ) -8/9/96 (bug fix) 7/30 change above for <Destroy> handlers broke many -things by making window available during Destroy handler. Reworked -fix for core dump to simply disallow creating children of half-dead -parents. (JO) +1/28/99 (configure change) Now support -pipe option on gcc. (RJ) -8/12/96 (bug fix) Fixed bug where using the Copy menu item on the -Macintosh would append a NULL character at the end of the text.

(stanton) -8/15/96 (configuration improvement) Changed the file patchlevel.h -to be tkPatch.h. This avoids conflict with the Tcl file and is now -in 8.3 format on the Windows platform. (RJ) +2/2/99 (bug fix) ENOTSUP and EOPNOTSUPP clashed on some Linux +variants. (stanton) -8/19/96 (bug fix) Fixed a bug under Windows where the initial window -position for a toplevel window was reported as +0+0, regardless of the -actual position. (SS) +2/2/99 (enhancement) The "open" command has been changed to use the +object interfaces. (stanton) -8/21/96 (bug fix) If the last character on a line in a text widget was -a space character that didn't completely fit, the text widget would -sometimes add an extra wrap line. (JO) +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) -8/22/96 (feature change) Complete rewrite of the grid geometry manager. -There is a new layout algorithm that produces better (but different) -layouts in many common cases. (SU) +2/2/99 (bug fix) Changed configure so Linux and IRIX shared libraries +are linked with the system libraries. (stanton) -8/22/96 (new feature) There are two new options for the grid geometry -manager, "grid update" which forces an immediate layout calculation, -and a "-pad" option to rowconfigure and columnconfigure that allows for -extra space around widgets. (SU) +2/2/99 (bug fix) Added support for BSDI 4.x (BSD/OS-4*) to the +configure script. (stanton) -8/22/96 (feature change) The order in which the grid geometry manager -reports slaves is now last-managed first. (SU) +2/2/99 (bug fix) Fixed bug where upvar could resurrect a namespace +variable after the namespace had been deleted. (stanton) -8/22/96 (feature change) The column and row weights in the grid -geometry manager are kept internally as integers, instead of floating -point values. Floating point values are still accepted on the command line, -but are truncated to integers. (SU) +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) -8/22/96 (new feature) There are four new commands for opening common -dialog boxes: tk_chooseColor, tk_getOpenFile, tk_getSaveFile and -tk_messageBox. Native dialog boxes are used wherever available. (IL) +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) -8/22/96 (new demos) Added "fsbox", "msgbox" and "clrpick" demos. (IL) +2/2/99 (bug fix) Deleting a renamed interp alias could result in a +panic. (stanton) -8/23/96 (feature change) Invoking the edit menu on the Macintosh now -generates the following virtual events <<Cut>>, <<Copy>>, <<Paste>>, -and <<Clear>> instead of faking key events. (RJ) +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 *** -8/25/96 (bug fix) Fixed a bug that would cause "grid x" to dump core. (SU) - -8/26/96 (new feature) Added the "unsupported1" command to the -Macintosh version of Tk. This command will allow you to set the style -of a new toplevel Window (much like overrideredirect). You can use -this to get access to all of the Native Mac window styles. This is to -hold you over until we get a more general solution added to the -toplevel command. (RJ) - -8/26/96 (new feature) Added support to handle the zoom box on a -Macintosh window. (Currently, you can only get a Tk window with a -zoom box by using the "unsupported1" command. (RJ) - -8/27/96 (documentation change) Removed old change bars (for changes in -Tk 4.1 and earlier releases) from manual entries. (JO) - ------------------ Released 4.2b1, 8/30/96 ----------------------- - -9/5/96 (bug fixes) Fixed several bugs in file dialogs: individual files -could be listed twice, if a long list of files were shown, and the view -scrolled to the right, and then a different file file was shown, the -scrollregion on the canvas wasn't being reset, so the file dialog was -broken from then on, added an update idletasks so that the watch -cursor was shown when the dialog was thinking. For the motif file -dialog, fixed the weights for resizing. On the clrpicker, fixed the -finalColor variable which caused problems when the OK button was -"clicked" before the dialog was mapped (in the test suite). Added Ioi's -last changes from before he left. For message boxes, if a single button -message box is shown (currently only 'ok'), it is set to be the default -even if not specified. (KC) - -9/5/96 (bug fix) Fixed bug on Macintosh where menus would appear in a -seemingly random location. (RJ) - -9/5/96 (bug fix) Text widgets had rounding problems with the "yview" -command that caused them sometimes to round to the line before the -correct one. (JO) - -9/5/96 (bug fix) Changed grab code to retry grabs after errors where -another application already has the grab. This is needed to get -around race conditions with some window managers and will hopefully -solve the grab errors that people see occasionally. (JO) - -9/6/96 (bug fix) Fixed x-y coordinate confusion problem with scaling -of window items in canvases. (JO) - -9/11/96 (bug fix) The open and save file dialogs would change the -current working directory under Windows. (SS) - -9/12/96 (bug fix) The Tk event system was delivering events to dead -windows, if the event handler got reentered during a Destroy event -handler. This could cause core dumps and other problems. (JO) - -9/20/96 (bug fix) In XFillRectangles under Windows, a brush was not -being deallocated. (SS) - -9/20/96 (bug fix) The Mac window manager used to generate a mouseUp -event for a top level that was recently raised to the front/active -window which often caused a tk(priv) error. The up event is no -longer generated with solves several problems. (RJ) - -9/25/96 (bug fix) The font code under Windows was leaking memory -whenever a new font was referenced using the three part font names. (SS) - -9/26/96 (bug fix) The tests for the common dialogs still used the 'testevent' -function. I updated these calls in clrpick.test, msgbox.test, filebox.test -to use the new event gereating mechanism. - -9/18/96 (bug fix) Long-standing bug in bind where <Button-1><Button-1> was -reported as <Double-Button-1>, but <Double-Key-a> was reported as "aa". (CS) - -9/27/96 (bug fix) Bindings didn't work on 64-bit machines due to changes -made for virtual events. (CS) - -9/30/96 (feature change) Binding for new virtual events included both -lower and upper-case, e.g., <<Copy>> was defined as <Control-c> and -<Control-C>. Previously, widgets were directly bound to only lower-case -bindings. The upper-case binding caused incompatibility with some existing -Tcl programs, so the upper case bindings for <<Cut>>, <<Copy>>, and <<Paste>> -were removed. (CS) - -9/30/96 (bug fix) The postscript code in the canvas widget now uses -channels to get and write .ps files which fixed a bug on the Mac where -an output file would have mixed EOL characters. In addition, I added -the ability for the prolog to come from the Tk shared library on the -Mac which makes it possible to have a standalone application. (RJ) - -10/1/96 (feature change) "grid forget" was renamed "grid remove". A new -command "grid forget" was added whose semantics are the same as "pack forget" -(SAU) +----------------- 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 *** -10/1/96 (feature change) grid no longer accepts floating point values for -row or column weights, integers must be used. (SAU) +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 *** -10/1/96 (feature change) "grid {column,row}configure <master> <index>" -returns a list of option value pairs for all of the row or column -constraints. It used to return an error. (SAU) +10/27/97 (enhancement) Bytecode compiler rewritten to use the new Tcl +parser. (BL) -10/1/96 (bug fix) "The way grid handles '^' short-cuts was re-written -to eliminate core dumps. (SAU) +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) -10/3/96 (feature change) A virtual event binding associated with a -given physical event is now considered less specific than a binding for -that same physical event, all other things being equal. (CS). +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) -10/3/96 (bug fix) Under Windows text placed on the clipboard did not -undergo CRLF translation when delivered to other applications.

(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) -10/10/96 (bug fix) Under Windows, 8-bit non-palette displays were not -handled properly. (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) -10/10/96 (bug fix) Under Windows, images of depth other than 8 or 24 -bits were not being rendered properly. (SS) +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) -10/10/96 (bug fix) Under Windows, bitmap subimages were not correctly -displayed. (SS) +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) -10/14/96 (bug fix) Under Window, wm resizable would constrain both -programatic resizes as well as user resizes. (SS) +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) ------------------ Released 4.2, 10/16/96 ----------------------- +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) -10/17/96 (bug fix) XCopyPlane was broken under Windows and would cause -a crash when used with a clipping bitmap. (SS) +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) -10/21/96 (bug fix) Added missing resources needed by tk_getOpenDialog -on the Macintosh to the shared library for Tk. (RJ) +1/8/98 (unix portability/configure) building from .../unix/targetName/ +subdirectories and simply using "../configure" should now work fine. (DL) -10/22/96 (bug fix) Invoking a menu with an Alt key sequence caused an -error due to a misplaced common in library/menu.tcl. (JO) - -10/23/96 (bug fix) Errors in files sourced by the Macintosh -"Source..." menu are now correctly reported via the background -error mechanism. (RJ) +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 *** -10/23/96 (bug fix) Fixed a bug in the Mac subwindow implementation -that caused refreshes to not occur for canvases with embedded -windows. (RJ) +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) -10/24/96 (bug fix) Provided workaround for Apple bug that doesn't -handle zooming correctly for floating windows. (RJ) +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) -10/24/96 (bug fix) Macintosh tearoff menus are now correctly -displayed as Mac floating windows. (RJ) +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) -11/1/96 (bug fix) Restored manual page for procedures like -Tk_CreateWindowFromPath and Tk_DestroyWindow; was accidentally deleted -when Tk_CreateMainWindow procedure was decommissioned. (JO) +----------------- Released 8.1a1, 1/22/98 ----------------------- -11/19/96 (bug fix) Fixed bugs in postscript code that would cause the -prefix to not be included and the output file to have the wrong -permissions. (RJ) +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 *** -12/2/96 (bug fix) Fixed problem with canvas lines where it didn't -compute bounding boxes correctly for zero-width lines: this could -potentially leave garbage on the screen when items were deleted or -moved. (JO) +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). + +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.

(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.

See the manual entry font.n - for details. - - Font requests always succeed now. If the requested font is not - available, Tk finds the closest available font and uses that one. - - Tk now supports named fonts whose precise attributes can be - changed dynamically. If a named font is changed, any widget - using that font updates itself to reflect the change. - - There is a new command "font" for creating named fonts and querying - various information about fonts. - - There are now officially supported C APIs for measuring and - displaying text. If you use these APIs now, your code will - automatically handle international text when internationalization - is added to Tk in a future release. See the manual entries - MeasureChar.3, TextLayout.3, and FontId.3. - - The old C procedures Tk_GetFontStruct, Tk_NameOfFontStruct, and - Tk_FreeFontStruct have been replaced with more portable procedures - Tk_GetFont, Tk_NameOfFont, and Tk_FreeFont. - *** POTENTIAL INCOMPATIBILITY *** -(CS) - -9/24/96 (bug fix) Under Windows, transient windows would be destroyed -if their master was destroyed, even if the transient window was not a -child of the master.

(SRP) - -3/4/97 (bug fix) Prevented core dump at exit if a <Destroy> binding on "." -gets invoked from destroying a nested widget and the binding causes the -interpreter to be deleted. The core dump was being caused by the -interpreter not being Tcl_Preserve'd during the destroy of ".". (JL) - -3/4/97 (bug fix) Under Unix, when embedded Tk is running in a separate -process, correctly handle a race condition: ignore cross-over messages from -the X server for windows that Tk thinks it had already deleted, when the -containing process deletes its container window. Some other race conditions -still remain, e.g. with pixmaps, colormaps and images. (JL) - -3/10/97 (bug fix) Prevented core dump in generic console code due to -following a NULL pointer when the console interpreter was already deleted. -This may happen due to different orders of deletion possible at exit. (JL) - -3/10/97 (bug fix) Fixed bug on Mac and Windows that caused time to be -ignored when considering if a single click was actually a double -click. (RJ) - -3/11/97 (feature change) A major oversight has been that although it was -documented that the Tk programmer was asking for a font in points (1/72 of an -inch), under Unix and Mac Tk was actually asking for a font in pixels, while -only under Windows was it using points. This caused applications to appear -much larger when run under Windows. Now, on all platforms the (purportedly) -correct size in points is used when asking for fonts. However, for -compatibility with existing tk4.2 applications that depend on fonts being of -specified pixel size, XLFDs retain their incorrect behavior of getting a -font in pixels. (CCS) +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.

[Bug: 1771] (stanton) -4/23/97 (feature change) Loosened the rules on parsing font names so that -unix-centric fonts in scripts don't break when run on Windows or Mac. -(1) Previously, an XLFD had to specify font name, weight, slant, and size; -now, a minimal XLFD (such as "*-times-*") will be accepted, and all -unspecified attributes will be given default values. (2) Previously, in the -{name size style ...} format, only the style was optional; now both the size -and the style are optional; this solves the problem of old scripts that -contain specifications of the form "-font fixed" or "-font times". (CCS) - -5/7/97 (new feature) Menus now send a virtual event <<MenuSelect>> -when an item is highlighted in a menu. Applications can use this to -implement context-sensitive help. (SRP) - -5/14/97 (bug fix) Fixed a race condition in the focus code where focus -could be taken away from a window incorrectly.

In Tk4.6, tearoff menus had the -"-tearoff" flag turned off. Now, the "-tearoff" flag is tracked just -as the other options are. Tearoff menus and menubars with the -"-tearoff" option set will not display the tearoff item. This means -that a given menu entry for a menu and a tearoff of that menu will -match now.

[Bug: 2450] (redman) -11/5/97 (bug fix) Embedding on Windows was using freed data (crashing -in safe.test with TCL_MEM_DEBUG). NB: Embedding is still not fully -implemented on Windows ! (It works mostly when Tk is embeded into it's -own Tk frame (safe::loadTk case), but not well with respect to resizing -with a toplevel container or with an external process). (DL) +7/30/99 (bug fix) Fixed launching of 16bit applications on Win9x from +wish. The command line was being primed with tclpip82.dll, but it was +ignored later. ------------------ Released 8.0p1, 11/7/97 ----------------------- +7/30/99 (bug fix) Added functions to stub table, patch provided by Jan +Nijtmans. [Bug: 2445] (hobbs) -11/20/97 (bug fix) Fixed bug on the Mac where the "package require" -command caused menus to stop working. (JI) +8/1/99 (bug fix) Changed Windows socket driver to terminate threads +by sending a message to the window rather than calling +TerminateThread(), which seems to leak about 4k from the helper +thread's stack space.

[Bug: 2496] (hobbs) -12/3/97 (bug fix/optimization) Removed unneeded 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 ... ...".

(JI) +8/9/99 (internal api change) Removed the TclpMutexLock and TclpMutexUnlock +APIs and added a new exported api, Tcl_GetAllocMutex. These APIs are all for +the mutex used in the simple memory allocators. By making this change +we are able to substitute different implementations of the thread-related +APIs without having to recompile the Tcl core. (welch) -Jan/9/98 (improvement) Allow applications to have custom init script -without having to patch the Tk core: Tk_Init will use an existing -"tkInit" proc if one exists in the interp where one tries to install Tk -instead of defining it's own (tkInit is the transient proc defined in -generic/tkInitScript.h that searches and sources tk.tcl and defines -the 'correct' tk_library). (DL) +8/9/99 (new C API) Tcl_GetChannelNames returns a list of open channel +names in the interpreter result. Still no Tcl-level version of this, +but server-like applications can use this to clean up files without +deleting interpreters. (welch) ----- Shipped as part of the plugin2.0 as 8.0p2Plugin2, Jan 15th 98 ---- +8/9/99 (bug fix) Traces were not firing on "info exists", which used to +happen in Tcl 7.6 and earlier.

(SS) +--------------- Released 8.2.0, August 17, 1999 ---------------------- -6/29/98 (compatibility patch) Added reserved fields to several Tk -structures to match additions made by Jan Nijtmans dash patch.

(JI) +9/21/99 (bug fix) fixed static buffer overflow problem. [Bug: 2483] (hobbs) -7/24/98 (feature change) Eliminated the static variable that sets -tk_library and simplified search order for tk.tcl. The tk_library -variable can now be set before calling Tk_Init to avoid doing any -searches. If it isn't set, then Tk checks env(TK_LIBRARY), relative -to tcl_library, an install directory relative to the executable, a -source directory relative to the executable, and a tk directory -relative to the source heirarchy containing the executable. See the -comment at the top of generic/tkInitScript.h for more details. (SS) +9/21/99 (bug fix) fixed end-int linsert interpretation.

You can -bind to the MouseWheel event and use the %D substitution to get the -delta the wheel moved. The "event generate" command has also been -enhanced with the -delta flag so you can generate these events from -Tcl. See the bind and event man pages for more details. The listbox -and text widgets' default bindings have been updated to understand -MouseWheel events. (RJ) +11/30/99 (bug fix) fixed setting of isNonBlocking flag in PipeBlockModeProc +so you can now close a non-blocking channel without waiting. -10/12/98 (performance improvement) Added hash table to canvas widget -that holds numeric ids for items. The hash table makes item lookup -almost constant time which improves certain canvas operations -(exspecially for canvases with large number items). Thanks to Mark -Weissman <weissman@gte.com> and Jan Nijtmans <Jan.Nijtmans@wxs.nl> -for submitting this improvement. (RJ) +11/30/99 (bug work-around) prevented the unloading of DLLs for Unix in +TclFinalizeLoad. This stops the seg fault on exit that some users would +see (ie with oratcl) when using DLLs that do nasty things like register +atexit handlers. -10/15/98 (bug fix) The -fill option to text items in the canvas did -not allow the empty string as an argument (meaning transparent) even -though every other item type did. Thanks to Sebastian Wangnick -<sebastian.wangnick@eurocontrol.be> for supplying this patch. (RJ) +12/07/99 (bug fix) fixes for 'expr + {[incr]}' and 'expr + {[error]}' +cases (different causes). -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 *** +--- Released 8.2.3, December 16, 1999 --- See ChangeLog for details --- -11/10/98 (feature change) The Macintosh menus will use the Appearance -Theme backgrounds, separators and menu shape, if Appearance version -1.0.1 or greater is installed. The version of Appearance that shipped -with MacOS 8.0 so it will not work with a straight 8.0, but it will -with MacOS 8.1 or later.

(stanton) +1999-10-28 (feature enhancement) added support for touch functionality by +extendeding 'file atime' and 'file mtime' to take an optional time argument -2/4/99 (bug fix) Changed so focus window is always set if -force is -specified. This fixes the problem on Windows where Tk does not -activate the window if it already has focus. (stanton) +1999-11-24 (feature enhancement) added 'fconfigure $sock -lasterror' +command to Windows to query the last error received on a serial socket. -2/4/99 (bug fix) Fixed so errors in console eval are reported -properly.

This avoids generating useless -declspec() attributes and makes the Windows makefile simpler. (stanton) +1999-12-10 (bug fix) removed check for vfork - Tcl now uses only fork in +exec. (hobbs) -2/4/99 (bug fix) Changed so keyboard shortcuts will only be found in -the current toplevel.

You do not need - Unicode fonts on your system in order to use tk or see international - characters. For those familiar with the Japanese or Chinese patches, - there is no "-kanjifont" option. Characters from any available fonts - will automatically be used if the widget's originally selected font is - not capable of displaying a given character. - - Textual widgets are international aware. For instance, cursor - positioning commands would now move the cursor forwards/back by 1 - international character, not by 1 byte. - - Input Method Editors (IMEs) work on Mac and Windows. Unix is still in - progress. - -7/7/97 (new feature) The send command now works for Microsoft -Windows.
