Raw Blame History

Recent user-visible changes to Tcl:
1. No more [command1] [command2] construct for grouping multiple
commands on a single command line.
2. Semi-colon now available for grouping commands on a line.
3. For a command to span multiple lines, must now use backslash-return
at the end of each line but the last.
4. "Var" command has been changed to "set".
5. Double-quotes now available as an argument grouping character.
6. "Return" may be used at top-level.
7. More backslash sequences available now. In particular, backslash-newline
may be used to join lines in command files.
8. New or modified built-in commands: case, return, for, glob, info,
print, return, set, source, string, uplevel.
9. After an error, the variable "errorInfo" is filled with a stack
trace showing what was being executed when the error occurred.
10. Command abbreviations are accepted when parsing commands, but
are not recommended except for purely-interactive commands.
11. $, set, and expr all complain now if a non-existent variable is
referenced.
12. History facilities exist now. See Tcl.man and Tcl_RecordAndEval.man.
13. Changed to distinguish between empty variables and those that don't
exist at all. Interfaces to Tcl_GetVar and Tcl_ParseVar have changed
(NULL return value is now possible). *** POTENTIAL INCOMPATIBILITY ***
14. Changed meaning of "level" argument to "uplevel" command (1 now means
"go up one level", not "go to level 1"; "#1" means "go to level 1").
*** POTENTIAL INCOMPATIBILITY ***
15. 3/19/90 Added "info exists" option to see if variable exists.
16. 3/19/90 Added "noAbbrev" variable to prohibit command abbreviations.
17. 3/19/90 Added extra errorInfo option to "error" command.
18. 3/21/90 Double-quotes now only affect space: command, variable,
and backslash substitutions still occur inside double-quotes.
*** POTENTIAL INCOMPATIBILITY ***
19. 3/21/90 Added support for \r.
20. 3/21/90 List, concat, eval, and glob commands all expect at least
one argument now. *** POTENTIAL INCOMPATIBILITY ***
21. 3/22/90 Added "?:" operators to expressions.
22. 3/25/90 Fixed bug in Tcl_Result that caused memory to get trashed.
------------------- Released version 3.1 ---------------------
23. 3/29/90 Fixed bug that caused "file a.b/c ext" to return ".b/c".
24. 3/29/90 Semi-colon is not treated specially when enclosed in
double-quotes.
------------------- Released version 3.2 ---------------------
25. 4/16/90 Rewrote "exec" not to use select or signals anymore.
Should be more Sys-V compatible, and no slower in the normal case.
26. 4/18/90 Rewrote "glob" to eliminate GNU code (there's no GNU code
left in Tcl, now), and added Tcl_TildeSubst procedure. Added automatic
tilde-substitution in many commands, including "glob".
------------------- Released version 3.3 ---------------------
27. 7/11/90 Added "Tcl_AppendResult" procedure.
28. 7/20/90 "History" with no options now defaults to "history info"
rather than to "history redo". Although this is a backward incompatibility,
it should only be used interactively and thus shouldn't present any
compatibility problems with scripts.
29. 7/20/90 Added "Tcl_GetInteger", "Tcl_GetDouble", and "Tcl_GetBoolean"
procedures.
30. 7/22/90 Removed "Tcl_WatchInterp" procedure: doesn't seem to be
necessary, since the same effect can be achieved with the deletion
callbacks on individual commands. *** POTENTIAL INCOMPATIBILITY ***
31. 7/23/90 Added variable tracing: Tcl_TraceVar, Tcl_UnTraceVar,
and Tcl_VarTraceInfo procedures, "trace" command.
32. 8/9/90 Mailed out list of all bug fixes since 3.3 release.
33. 8/29/90 Fixed bugs in Tcl_Merge relating to backslashes and
semi-colons. Mailed out patch.
34. 9/3/90 Fixed bug in tclBasic.c: quotes weren't quoting ]'s.
Mailed out patch.
35. 9/19/90 Rewrote exec to always use files both for input and
output to the process. The old pipe-based version didn't work if
the exec'ed process forked a child and then exited: Tcl waited
around for stdout to get closed, which didn't happen until the
grandchild exited.
36. 11/5/90 ERR_IN_PROGRESS flag wasn't being cleared soon enough
in Tcl_Eval, allowing error messages from different commands to
pile up in $errorInfo. Fixed by re-arranging code in Tcl_Eval that
re-initializes result and ERR_IN_PROGRESS flag. Didn't mail out
patch: changes too complicated to describe.
37. 12/19/90 Added Tcl_VarEval procedure as a convenience for
assembling and executing Tcl commands.
38. 1/29/91 Fixed core leak in Tcl_AddErrorInfo. Also changed procedure
and Tcl_Eval so that first call to Tcl_AddErrorInfo need not come from
Tcl_Eval.
----------------- Released version 5.0 with Tk ------------------
39. 4/3/91 Removed change bars from manual entries, leaving only those
that came after version 3.3 was released.
40. 5/17/91 Changed tests to conform to Mary Ann May-Pumphrey's approach.
41. 5/23/91 Massive revision to Tcl parser to simplify the implementation
of string and floating-point support in expressions. Newlines inside
[] are now treated as command separators rather than word separators
(this makes newline treatment consistent throughout Tcl).
*** POTENTIAL INCOMPATIBILITY ***
42. 5/23/91 Massive rewrite of expression code to support floating-point
values and simple string comparisons. The C interfaces to expression
routines have changed (Tcl_Expr is replaced by Tcl_ExprLong, Tcl_ExprDouble,
etc.), but all old Tcl expression strings should be accepted by the new
expression code.
*** POTENTIAL INCOMPATIBILITY ***
43. 5/23/91 Modified tclHistory.c to check for negative "keep" value.
44. 5/23/91 Modified Tcl_Backslash to handle backslash-newline. It now
returns 0 to indicate that a backslash sequence should be replaced by
no character at all.
*** POTENTIAL INCOMPATIBILITY ***
45. 5/29/91 Modified to use ANSI C function prototypes. Must set
"USE_ANSI" switch when compiling to get prototypes.
46. 5/29/91 Completed test suite by providing tests for all of the
built-in Tcl commands.
47. 5/29/91 Changed Tcl_Concat to eliminate leading and trailing
white-space in each of the things it concatenates and to ignore
elements that are empty or have only white space in them. This
produces cleaner output from the "concat" command.
*** POTENTIAL INCOMPATIBILITY ***
48. 5/31/91 Changed "set" command and Tcl_SetVar procedure to return
new value of variable.
49. 6/1/91 Added "while" and "cd" commands.
50. 6/1/91 Changed "exec" to delete the last character of program
output if it is a newline. In most cases this makes it easier to
process program-generated output.
*** POTENTIAL INCOMPATIBILITY ***
51. 6/1/91 Made sure that pointers are never used after freeing them.
52. 6/1/91 Fixed bug in TclWordEnd where it wasn't dealing with
[] inside quotes correctly.
53. 6/8/91 Fixed exec.test to accept return values of either 1 or
255 from "false" command.
54. 7/6/91 Massive overhaul of variable management. Associative
arrays now available, along with "unset" command (and Tcl_UnsetVar
procedure). Variable traces have been completely reworked:
interfaces different both from Tcl and C, and multiple traces may
exist on same variable. Can no longer redefine existing local
variable to be global. Calling sequences have changed slightly
for Tcl_GetVar and Tcl_SetVar ("global" is now "flags"). Tcl_SetVar
can fail and return a NULL result. New forms of variable-manipulation
procedures: Tcl_GetVar2, Tcl_SetVar2, etc. Syntax of variable
$-notation changed to support array indexing.
*** POTENTIAL INCOMPATIBILITY ***
55. 7/6/91 Added new list-manipulation procedures: Tcl_ScanElement,
Tcl_ConvertElement, Tcl_AppendElement.
56. 7/12/91 Created new procedure Tcl_EvalFile, which does most of the
work of the "source" command.
57. 7/20/91 Major reworking of "exec" command to allow pipelines,
more redirection, background. Added new procedures Tcl_Fork,
Tcl_WaitPids, Tcl_DetachPids, and Tcl_CreatePipeline. The old
"< input" notation has been replaced by "<< input" ("<" is for
redirection from a file). Also handles error returns and abnormal
terminations (e.g. signals) differently.
*** POTENTIAL INCOMPATIBILITY ***
58. 7/21/91 Added "append" and "lappend" commands.
59. 7/22/91 Reworked error messages and manual entries to use
?x? as the notation for an optional argument x, instead of [x]. The
bracket notation was often confused with the use of brackets for
command substitution. Also modified error messages to be more
consistent.
60. 7/23/91 Tcl_DeleteCommand now returns an indication of whether
or not the command actually existed, and the "rename" command uses
this information to return an error if an attempt is made to delete
a non-existent command.
*** POTENTIAL INCOMPATIBILITY ***
61. 7/25/91 Added new "errorCode" mechanism, along with procedures
Tcl_SetErrorCode, Tcl_UnixError, and Tcl_ResetResult. Renamed
Tcl_Return to Tcl_SetResult, but left a #define for Tcl_Return to
avoid compatibility problems.
62. 7/26/91 Extended "case" command with alternate syntax where all
patterns and commands are together in a single list argument: makes
it easier to write multi-line case statements.
63. 7/27/91 Changed "print" command to perform tilde-substitution on
the file name.
64. 7/27/91 Added "tolower", "toupper", "trim", "trimleft", and "trimright"
options to "string" command.
65. 7/29/91 Added "atime", "mtime", "size", and "stat" options to "file"
command.
66. 8/1/91 Added "split" and "join" commands.
67. 8/11/91 Added commands for file I/O, including "open", "close",
"read", "gets", "puts", "flush", "eof", "seek", and "tell".
68. 8/14/91 Switched to use a hash table for command lookups. Command
abbreviations no longer have direct support in the Tcl interpreter, but
it should be possible to simulate them with the auto-load features
described below. The "noAbbrev" variable is no longer used by Tcl.
*** POTENTIAL INCOMPATIBILITY ***
68.5 8/15/91 Added support for "unknown" command, which can be used to
complete abbreviations, auto-load library files, auto-exec shell
commands, etc.
69. 8/15/91 Added -nocomplain switch to "glob" command.
70. 8/20/91 Added "info library" option and TCL_LIBRARY #define. Also
added "info script" option.
71. 8/20/91 Changed "file" command to take "option" argument as first
argument (before file name), for consistency with other Tcl commands.
*** POTENTIAL INCOMPATIBILITY ***
72. 8/20/91 Changed format of information in $errorInfo variable:
comments such as
("while" body line 1)
are now on separate lines from commands being executed.
*** POTENTIAL INCOMPATIBILITY ***
73. 8/20/91 Changed Tcl_AppendResult so that it (eventually) frees
large buffers that it allocates.
74. 8/21/91 Added "linsert", "lreplace", "lsearch", and "lsort"
commands.
75. 8/28/91 Added "incr" and "exit" commands.
76. 8/30/91 Added "regexp" and "regsub" commands.
77. 9/4/91 Changed "dynamic" field in interpreters to "freeProc" (procedure
address). This allows for alternative storage managers.
*** POTENTIAL INCOMPATIBILITY ***
78. 9/6/91 Added "index", "length", and "range" options to "string"
command. Added "lindex", "llength", and "lrange" commands.
79. 9/8/91 Removed "index", "length", "print" and "range" commands.
"Print" is redundant with "puts", but less general, and the other
commands are replaced with the new commands described in change 78
above.
*** POTENTIAL INCOMPATIBILITY ***
80. 9/8/91 Changed history revision to occur even when history command
is nested; needed in order to allow "history" to be invoked from
"unknown" procedure.
81. 9/13/91 Changed "panic" not to use vfprintf (it's uglier and less
general now, but makes it easier to run Tcl on systems that don't
have vfprintf). Also changed "strerror" not to redeclare sys_errlist.
82. 9/19/91 Lots of changes to improve portability to different UNIX
systems, including addition of "config" script to adapt Tcl to the
configuration of the system it's being compiled on.
83. 9/22/91 Added "pwd" command.
84. 9/22/91 Renamed manual pages so that their filenames are no more
than 14 characters in length, moved to "doc" subdirectory.
85. 9/24/91 Redid manual entries so they contain the supplemental
macros that they need; can just print with "troff -man" or "man"
now.
86. 9/26/91 Created initial version of script library, including
a version of "unknown" that does auto-loading, auto-execution, and
abbreviation expansion. This library is used by tclTest
automatically. See the "library" manual entry for details.
----------------- Released version 6.0, 9/26/91 ------------------
87. 9/30/91 Made "string tolower" and "string toupper" check case
before converting: on some systems, "tolower" and "toupper" assume
that character already has particular case.
88. 9/30/91 Fixed bug in Tcl_SetResult: wasn't always setting freeProc
correctly when called with NULL value. This tended to cause memory
allocation errors later.
89. 10/3/91 Added "upvar" command.
90. 10/4/91 Changed "format" so that internally it converts %D to %ld,
%U to %lu, %O to %lo, and %F to %f. This eliminates some compatibility
problems on some machines without affecting behavior.
91. 10/10/91 Fixed bug in "regsub" that caused core dumps with the -all
option when the last match wasn't at the end of the string.
92. 10/17/91 Fixed problems with backslash sequences: \r support was
incomplete and \f and \v weren't supported at all.
93. 10/24/91 Added Tcl_InitHistory procedure.
94. 10/24/91 Changed "regexp" to store "-1 -1" in subMatchVars that
don't match, rather than returning an error.
95. 10/27/91 Modified "regexp" to return actual strings in matchVar
and subMatchVars instead of indices. Added "-indices" switch to cause
indices to be returned.
*** POTENTIAL INCOMPATIBILITY ***
96. 10/27/91 Fixed bug in "scan" where it used hardwired constants for
sizes of floats and doubles instead of using "sizeof".
97. 10/31/91 Fixed bug in tclParse.c where parse-related error messages
weren't being storage-managed correctly, causing spurious free's.
98. 10/31/91 Form feed and vertical tab characters are now considered
to be space characters by the parser.
99. 10/31/91 Added TCL_LEAVE_ERR_MSG flag to procedures like Tcl_SetVar.
100. 11/7/91 Fixed bug in "case" where "in" argument couldn't be omitted
if all case branches were embedded in a single list.
101. 11/7/91 Switched to use "pid_t" and "uid_t" and other official
POSIC types and function prototypes.
----------------- Released version 6.1, 11/7/91 ------------------
102. 12/2/91 Modified Tcl_ScanElement and Tcl_ConvertElement in several
ways. First, allowed caller to request that only backslashes be used
(no braces). Second, made Tcl_ConvertElement more aggressive in using
backslashes for braces and quotes.
103. 12/5/91 Added "type", "lstat", and "readlink" options to "file"
command, plus added new "type" element to output of "stat" and "lstat"
options.
104. 12/10/91 Manual entries had first lines that caused "man" program
to try weird preprocessor. Added blank comment lines to fix problem.
105. 12/16/91 Fixed a few bugs in auto_mkindex proc: wasn't handling
errors properly, and hadn't been upgraded for new "regexp" syntax.
106. 1/2/92 Fixed bug in "file" command where it didn't properly handle
a file names containing tildes where the indicated user doesn't exist.
107. 1/2/92 Fixed lots of cases in tclUnixStr.c where two different
errno symbols (e.g. EWOULDBLOCK and EAGAIN) have the same number; Tcl
will only use one of them.
108. 1/2/92 Lots of changes to configuration script to handle many more
systems more gracefully. E.g. should now detect the bogus strtoul that
comes with AIX and substitute Tcl's own version instead.
----------------- Released version 6.2, 1/10/92 ------------------
109. 1/20/92 Config didn't have code to actually use "uid_t" variable
to set TCL_UIT_T #define.
110. 2/10/92 Tcl_Eval didn't properly reset "numLevels" variable when
too-deep recursion occurred.
111. 2/29/92 Added "on" and "off" to keywords accepted by Tcl_GetBoolean.
112. 3/19/92 Config wasn't installing default version of strtod.c for
systems that don't have one in libc.a.
113. 3/23/92 Fixed bug in tclExpr.c where numbers with leading "."s,
like 0.75, couldn't be properly substituted into expressions with
variable or command substitution.
114. 3/25/92 Fixed bug in tclUnixAZ.c where "gets" command wasn't
checking to make sure that it was able to write the variable OK.
115. 4/16/92 Fixed bug in tclUnixAZ.c where "read" command didn't
compute file size right for device files.
116. 4/23/92 Fixed but in tclCmdMZ.c where "trace vinfo" was overwriting
the trace command.
----------------- Released version 6.3, 5/1/92 ------------------
117. 5/1/92 Added Tcl_GlobalEval.
118. 6/1/92 Changed auto-load facility to source files at global level.
119. 6/8/92 Tcl_ParseVar wasn't always setting termPtr after errors, which
sometimes caused core dumps.
120. 6/21/92 Fixed bug in initialization of regexp pattern cache. This
bug caused segmentation violations in regexp commands under some conditions.
121. 6/22/92 Changed implementation of "glob" command to eliminate
trailing slashes on directory names: they confuse some systems. There
shouldn't be any user-visible changes in functionality except for names
in error messages not having trailing slashes.
122. 7/2/92 Fixed bug that caused 'string match ** ""' to return 0.
123. 7/2/92 Fixed bug in Tcl_CreateCmdBuf where it wasn't initializing
the buffer to an empty string.
124. 7/6/92 Fixed bug in "case" command where it used NULL pattern string
after errors in the "default" clause.
125. 7/25/92 Speeded up auto_load procedure: don't reread all the index
files unless the path has changed.
126. 8/3/92 Changed tclUnix.h to define MAXPATHLEN from PATH_MAX, not
_POSIX_PATH_MAX.
----------------- Released version 6.4, 8/7/92 ------------------
127. 8/10/92 Changed tclBasic.c so that comment lines can be continued by
putting a backslash before the newline.
128. 8/21/92 Modified "unknown" to allow the source-ing of a file for
an auto-load to trigger other nested auto-loads, as long as there isn't
any recursion on the same command name.
129. 8/25/92 Modified "format" command to allow " " and "+" flags, and
allow flags in any order.
130. 9/14/92 Modified Tcl_ParseVar so that it doesn't actually attempt
to look up the variable if "noEval" mode is in effect in the interpreter
(it just parses the name). This avoids the errors that used to occur
in statements like "expr {[info exists foo] && $foo}".
131. 9/14/92 Fixed bug in "uplevel" command where it didn't output the
correct error message if a level was specified but no command.
132. 9/14/92 Renamed manual entries to have extensions like .3 and .n,
and added "install" target to Makefile.
133. 9/18/92 Modified "unknown" command to emulate !!, !<num>, and
^<old>^<new> csh history substitutions.
134. 9/21/92 Made the config script cleverer about figuring out which
switches to pass to "nm".
135. 9/23/92 Fixed tclVar.c to be sure to copy flags when growing variables.
Used to forget about traces in progress and make extra recursive calls
on trace procs.
136. 9/28/92 Fixed bug in auto_reset where it was unsetting variables
that might not exist.
137. 10/7/92 Changed "parray" library procedure to print any array
accessible to caller, local or global.
138. 10/15/92 Fixed bug where propagation of new environment variable
values among interpreters took N! time if there exist N interpreters.
139. 10/16/92 Changed auto_reset procedure so that it also deletes any
existing procedures that are in the auto_load index (the assumption is
that they should be re-loaded to get the latest versions).
140. 10/21/92 Fixed bug that caused lists to be incorrectly generated
for elements that contained backslash-newline sequences.
141. 12/9/92 Added support for TCL_LIBRARY environment variable: use
it as library location if it's present.
142. 12/9/92 Added "info complete" command, Tcl_CommandComplete procedure.
143. 12/16/92 Changed the Makefile to check to make sure "config" has been
run (can't run config directly from the Makefile because it modifies the
Makefile; thus make has to be run again after running config).
----------------- Released version 6.5, 12/17/92 ------------------
144. 12/21/92 Changed config to look in several places for libc file.
145. 12/23/92 Added "elseif" support to if. Also, "then", "else", and
"elseif" may no longer be abbreviated.
*** POTENTIAL INCOMPATIBILITY ***
146. 12/28/92 Changed "puts" and "read" to support initial "-nonewline"
switch instead of additional "nonewline" argument. The old form is
still supported, but it is discouraged and is no longer documented.
Also changed "puts" to make the file argument default to stdout: e.g.
"puts foo" will print foo on standard output.
147. 1/6/93 Fixed bug whereby backslash-newline wasn't working when
typed interactively, or in "info complete".
148. 1/22/93 Fixed bugs in "lreplace" and "linsert" where close
quotes were being lost from last element before replacement or
insertion.
149. 1/29/93 Fixed bug in Tcl_AssembleCmd where it wasn't requiring
a newline at the end of a line before considering a command to be
complete. The bug caused some very long lines in script files to
be processed as multiple separate commands.
150. 1/29/93 Various changes in Makefile to add more configuration
options, simplify installation, fix bugs (e.g. don't use -f switch
for cp), etc.
151. 1/29/93 Changed "name1" and "name2" identifiers to "part1" and
"part2" to avoid name conflicts with stupid C++ implementations that
use "name1" and "name2" in a reserved way.
152. 2/1/93 Added "putenv" procedure to replace the standard system
version so that it will work correctly with Tcl's environment handling.
----------------- Released version 6.6, 2/5/93 ------------------
153. 2/10/93 Fixed bugs in config script: missing "endif" in libc loop,
and tried to use strncasecmp.c instead of strcasecmp.c.
154. 2/10/93 Makefile improvements: added RANLIB variable for easier
Sys-V configuration, added SHELL variable for SGI systems.
----------------- Released version 6.7, 2/11/93 ------------------
153. 2/6/93 Changes in backslash processing:
- \Cx, \Mx, \CMx, \e sequences no longer special
- \<newline> also eats up any space after the newline, replacing
the whole sequence with a single space character
- Hex sequences like \x24 are now supported, along with ANSI C's \a.
- "format" no longer does backslash processing on its format string
- there is no longer any special meaning to a 0 return value from
Tcl_Backslash
- unknown backslash sequences, like (e.g. \*), are replaced with
the following character (e.g. *), instead of just treating the
backslash as an ordinary character.
*** POTENTIAL INCOMPATIBILITY ***
154. 2/6/93 Updated all copyright notices. The meaning hasn't changed
at all but the wording does a better job of protecting U.C. from
liability (according to U.C. lawyers, anyway).
155. 2/6/93 Changed "regsub" so that it overwrites the result variable
in all cases, even if there is no match.
*** POTENTIAL INCOMPATIBILITY ***
156. 2/8/93 Added support for XPG3 %n$ conversion specifiers to "format"
command.
157. 2/17/93 Fixed bug in Tcl_Eval where errors due to infinite
recursion could result in core dumps.
158. 2/17/93 Improved the auto-load mechanism to deal gracefully (i.e.
return an error) with a situation where a library file that supposedly
defines a procedure doesn't actually define it.
159. 2/17/93 Renamed Tcl_UnixError procedure to Tcl_PosixError, and
changed errorCode variable usage to use POSIX as keyword instead of
UNIX.
*** POTENTIAL INCOMPATIBILITY ***
160. 2/19/93 Changes to exec and process control:
- Added support for >>, >&, >>&, |&, <@, >@, and >&@ forms of redirection.
- When exec puts processes into background, it returns a list of
their pids as result.
- Added support for <file, >file, etc. (i.e. no space between
">" and file name.
- Added -keepnewline option.
- Deleted Tcl_Fork and Tcl_WaitPids procedures (just use fork and
waitpid instead).
- Added waitpid compatibility procedure for systems that don't have
it.
- Added Tcl_ReapDetachedProcs procedure.
- Changed "exec" to return an error if there is stderr output, even
if the command returns a 0 exit status (it's always been documented
this way, but the implementation wasn't correct).
- If a process returns a non-zero exit status but doesn't generate
any diagnostic output, then Tcl generates an error message for it.
*** POTENTIAL INCOMPATIBILITY ***
161. 2/25/93 Fixed two memory-management problems having to do with
managing the old result during variable trace callbacks.
162. 3/1/93 Added dynamic string library: Tcl_DStringInit, Tcl_DStringAppend,
Tcl_DStringFree, Tcl_DStringResult, etc.
163. 3/1/93 Modified glob command to only return the names of files that
exist, and to only return names ending in "/" if the file is a directory.
*** POTENTIAL INCOMPATIBILITY ***
164. 3/19/93 Modified not to use system calls like "read" directly,
but instead to use special Tcl procedures that retry automatically
if interrupted by signals.
165. 4/3/93 Eliminated "noSep" argument to Tcl_AppendElement, plus
TCL_NO_SPACE flag for Tcl_SetVar and Tcl_SetVar2.
*** POTENTIAL INCOMPATIBILITY ***
166. 4/3/93 Eliminated "flags" and "termPtr" arguments to Tcl_Eval.
*** POTENTIAL INCOMPATIBILITY ***
167. 4/3/93 Changes to expressions:
- The "expr" command now accepts multiple arguments, which are
concatenated together with space separators.
- Integers aren't automatically promoted to floating-point if they
overflow the word size: errors are generated instead.
- Tcl can now handle "NaN" and other special values if the underlying
library procedures handle them.
- When printing floating-point numbers, Tcl ensures that there is a "."
or "e" in the number, so it can't be treated as an integer accidentally.
The procedure Tcl_PrintDouble is available to provide this function
in other contexts. Also, the variable "tcl_precision" can be used
to set the precision for printing (must be a decimal number giving
digits of precision).
- Expressions now support transcendental and other functions, e.g. sin,
acos, hypot, ceil, and round. Can add new math functions with
Tcl_CreateMathFunc().
- Boolean expressions can now have any of the string values accepted
by Tcl_GetBoolean, such as "yes" or "no".
*** POTENTIAL INCOMPATIBILITY ***
168. 4/5/93 Changed Tcl_UnsetVar and Tcl_UnsetVar2 to return TCL_OK
or TCL_ERROR instead of 0 or -1.
*** POTENTIAL INCOMPATIBILITY ***
169. 4/5/93 Eliminated Tcl_CmdBuf structure and associated procedures;
can use Tcl_DStrings instead.
*** POTENTIAL INCOMPATIBILITY ***
170. 4/8/93 Changed interface to Tcl_TildeSubst to use a dynamic
string for buffer space. This makes the procedure re-entrant and
thread-safe, whereas it wasn't before.
*** POTENTIAL INCOMPATIBILITY ***
171. 4/14/93 Eliminated tclHash.h, and moved everything from it to
tcl.h
*** POTENTIAL INCOMPATIBILITY ***
172. 4/15/93 Eliminated Tcl_InitHistory, made "history" command always
be part of interpreter.
*** POTENTIAL INCOMPATIBILITY ***
173. 4/16/93 Modified "file" command so that "readable" option always
exists, even on machines that don't support symbolic links (always returns
same error as if the file wasn't a symbolic link).
174. 4/26/93 Fixed bugs in "regsub" where ^ patterns didn't get handled
right (pretended not to match when it really did, and looped infinitely
if -all was specified).
175. 4/29/93 Various improvements in the handling of variables:
- Can create variables and array elements during a read trace.
- Can delete variables during traces (note: unset traces will be
invoked when this happens).
- Can upvar to array elements.
- Can retarget an upvar to another variable by re-issuing the
upvar command with a different "other" variable.
176. 5/3/93 Added Tcl_GetCommandInfo, which returns info about a Tcl
command such as whether it exists and its ClientData. Also added
Tcl_SetCommandInfo, which allows any of this information to be modified
and also allows a command's delete procedure to have a different
ClientData value than its command procedure.
177. 5/5/93 Added Tcl_RegExpMatch procedure.
178. 5/6/93 Fixed bug in "scan" where it didn't properly handle
%% conversion specifiers. Also changed "scan" to use Tcl_PrintDouble
for printing real values.
179. 5/7/93 Added "-exact", "-glob", and "-regexp" options to "lsearch"
command to allow different kinds of pattern matching.
180. 5/7/93 Added many new switches to "lsort" to control the sorting
process: "-ascii", "-integer", "-real", "-command", "-increasing",
and "-decreasing".
181. 5/10/93 Changes to file I/O:
- Modified "open" command to support a list of POSIX access flags
like {WRONLY CREAT TRUNC} in addition to current fopen-style
access modes. Also added "permissions" argument to set permissions
of newly-created files.
- Fixed Scott Bolte's bug (can close stdin etc. in application and
then re-open them with Tcl commands).
- Exported access to Tcl's file table with new procedures Tcl_EnterFile
and Tcl_GetOpenFile.
182. 5/15/93 Added new "pid" command, which can be used to retrieve
either the current process id or a list of the process ids in a
pipeline opened with "open |..."
183. 6/3/93 Changed to use GNU autoconfig for configuration instead of
the home-brew "config" script. Also made many other configuration-related
changes, such as using <unistd.h> instead of explicitly declaring system
calls in tclUnix.h.
184. 6/4/93 Fixed bug where core-dumps could occur if a procedure
redefined itself (the memory for the procedure's body could get
reallocated in the middle of evaluating the body); implemented
simple reference count mechanism.
185. 6/5/93 Changed tclIndex file format in two ways: (a) it's now
eval-ed instead of parsed, which makes it 3-4x faster; (b) the entries
in auto_index are now commands to evaluate, which allows commands to
be loaded in different ways such as dynamic-loading of C code. The
old tclIndex file format is still supported.
186. 6/7/93 Eliminated tclTest program, added new "tclsh" program
that is more like wish (allows script files to be invoked automatically
using "#!/usr/local/bin/tclsh", makes arguments available to script,
etc.). Added support for Tcl_AppInit plus default version; this
allows new Tcl applications to be created without modifying the
main program for tclsh.
187. 6/7/93 Fixed bug in TclWordEnd that kept backslash-newline from
working correctly in some cases during interactive input.
188. 6/9/93 Added Tcl_LinkVar and related procedures, which automatically
keep a Tcl variable in sync with a C variable.
189. 6/16/93 Increased maximum nesting depth from 100 to 1000.
190. 6/16/93 Modified "trace var" command so that error messages from
within traces are returned properly as the result of the variable
access, instead of the generic "access disallowed by trace command"
message.
191. 6/16/93 Added Tcl_CallWhenDeleted to provide callbacks when an
interpreter is deleted (same functionality as Tcl_WatchInterp, which
used to exist in versions before 6.0).
193. 6/16/93 Added "-code" argument to "return" command; it's there
primarily for completeness, so that procedures implementing control
constructs can reflect exceptional conditions back to their callers.
194. 6/16/93 Split up Tcl.n to make separate manual entries for each
Tcl command. Tcl.n now contains a summary of the language syntax.
195. 6/17/93 Added new "switch" command to replace "case": allows
alternate forms of pattern matching (exact, glob, regexp), replaces
pattern lists with single patterns (but you can use "-" bodies to
share one body among several patterns), eliminates "in" noise word.
"Case" command is now obsolete.
196. 6/17/93 Changed the "exec", "glob", "regexp", and "regsub" commands
to include a "--" switch. All initial arguments starting with "-" are now
treated as switches unless a "--" switch is present to end the list.
*** POTENTIAL INCOMPATIBILITY ***
197. 6/17/93 Changed auto-exec so that the subprocess gets stdin, stdout,
and stderr from the parent. This allows truly interactive sub-processes
(e.g. vi) to be auto-exec'ed from a tcl shell command line.
198. 6/18/93 Added patchlevel.h, for use in coordinating future patch
releases, and also added "info patchlevel" command to make the patch
level available to Tcl scripts.
199. 6/19/93 Modified "glob" command so that a leading "//" in a name
gets left as is (this is needed for systems like Apollos where "//" is
the super-root; Tcl used to collapse the two slashes into a single
slash).
200. 7/7/93 Added Tcl_SetRecursionLimit procedure so that the maximum
allowable nesting depth can be controlled for an interpreter from C.
----------------- Released version 7.0 Beta 1, 7/9/93 ------------------
201. 7/12/93 Modified Tcl_GetInt and tclExpr.c so that full-precision
unsigned integers can be specified without overflow errors.
202. 7/12/93 Configuration changes: eliminate leading blank line in
configure script; provide separate targets in Makefile for installing
binary and non-binary information; check for size_t and a few other
potentially missing typedefs; don't put tclAppInit.o into libtcl.a;
better checks for matherr support.
203. 7/14/93 Changed tclExpr.c to check the termination pointer before
errno after strtod calls, to avoid problems with some versions of
strtod that set errno in unexpected ways.
204. 7/16/93 Changed "scan" command to be more ANSI-conformant:
eliminated %F, %D, etc., added code to ignore "l", "h", and "L"
modifiers but always convert %e, %f, and %g with implicit "l";
also added support for %u and %i. Also changed "format" command
to eliminate %D, %U, %O, and add %i.
*** POTENTIAL INCOMPATIBILITY ***
205. 7/17/93 Changed "uplevel" and "upvar" so that they can be used
from global level to global level: this used to generate an error.
206. 7/19/93 Renamed "setenv", "putenv", and "unsetenv" procedures
to avoid conflicts with system procedures with the same names. If
you want Tcl's procedures to override the system procedures, do it
in the Makefile (instructions are in the Makefile).
*** POTENTIAL INCOMPATIBILITY ***
----------------- Released version 7.0 Beta 2, 7/21/93 ------------------
207. 7/21/93 Fixed bug in tclVar.c where freed memory was accidentally
used if a procedure returned an element of a local array.
208. 7/22/93 Fixed bug in "unknown" where it didn't properly handle
errors occurring in the "auto_load" procedure, leaving its state
inconsistent.
209. 7/23/93 Changed exec's ">2" redirection operator to "2>" for
consistency with sh. This is incompatible with earlier beta releases
of 7.0 but not with pre-7.0 releases, which didn't support either
operator.
210. 7/28/93 Changed backslash-newline handling so that the resulting
space character *is* treated as a word separator unless the backslash
sequence is in quotes or braces. This is incompatible with 7.0b1
and 7.0b2 but is more compatible with pre-7.0 versions that the b1
and b2 releases were.
211. 7/28/93 Eliminated Tcl_LinkedVarWritable, added TCL_LINK_READ_ONLY to
Tcl_LinkVar to accomplish same purpose. This change is incompatible
with earlier beta releases, but not with releases before Tcl 7.0.
212. 7/29/93 Renamed regexp C functions so they won't clash with POSIX
regexp functions that use the same name.
213. 8/3/93 Added "-errorinfo" and "-errorcode" options to "return"
command: these allow for much better handling of the errorInfo
and errorCode variables in some cases.
214. 8/12/93 Changed "expr" so that % always returns a remainder with
the same sign as the divisor and absolute value smaller than the
divisor.
215. 8/14/93 Turned off auto-exec in "unknown" unless the command
was typed interactively. This means you must use "exec" when
invoking subprocesses, unless it's a command that's typed interactively.
*** POTENTIAL INCOMPATIBILITY ***
216. 8/14/93 Added support for tcl_prompt1 and tcl_prompt2 variables
to tclMain.c: makes prompts user-settable.
217. 8/14/93 Added asynchronous handlers (Tcl_AsyncCreate etc.) so
that signals can be taken cleanly by Tcl applications.
218. 8/16/93 Moved information about open files from the interpreter
structure to global variables so that a file can be opened in one
interpreter and read or written in another.
219. 8/16/93 Removed ENV_FLAGS from Makefile, so that there's no
official support for overriding setenv, unsetenv, and putenv.
220. 8/20/93 Various configuration improvements: coerce chars
to unsigned chars before using macros like isspace; source ~/.tclshrc
file during initialization if it exists and program is running
interactively; allow there to be directories in auto_path that don't
exist or don't have tclIndex files (ignore them); added Tcl_Init
procedure and changed Tcl_AppInit to call it.
221. 8/21/93 Fixed bug in expr where "+", "-", and " " were all
getting treated as integers with value 0.
222. 8/26/93 Added "tcl_interactive" variable to tclsh.
223. 8/27/93 Added procedure Tcl_FilePermissions to return whether a
given file can be read or written or both. Modified Tcl_EnterFile
to take a permissions mask rather than separate read and write arguments.
224. 8/28/93 Fixed performance bug in "glob" command (unnecessary call
to "access" for each file caused a 5-10x slow-down for big directories).
----------------- Released version 7.0 Beta 3, 8/28/93 ------------------
225. 9/9/93 Renamed regexp.h to tclRegexp.h to avoid conflicts with system
include file by same name.
226. 9/9/93 Added Tcl_DontCallWhenDeleted.
227. 9/16/93 Changed not to call exit C procedure directly; instead
always invoke "exit" Tcl command so that application can redefine the
command to do additional cleanup.
228. 9/17/93 Changed auto-exec to handle names that contain slashes
(i.e. don't use PATH for them).
229. 9/23/93 Fixed bug in "read" and "gets" commands where they didn't
clear EOF conditions.
----------------- Released version 7.0, 9/29/93 ------------------
230. 10/7/93 "Scan" command wasn't properly aligning things in memory,
so segmentation faults could arise under some circumstances.
231. 10/7/93 Fixed bug in Tcl_ConvertElement where it forgot to
backslash leading curly brace when creating lists.
232. 10/7/93 Eliminated dependency of tclMain.c on tclInt.h and
tclUnix.h, so that people can copy the file out of the Tcl source
directory to make modified private versions.
233. 10/8/93 Fixed bug in auto-loader that reversed the priority order
of entries in auto_path for new-style index files. Now things are
back to the way they were before 3.0: first in auto_path is always
highest priority.
234. 10/13/93 Fixed bug where Tcl_CommandComplete didn't recognize
comments and treat them as such. Thus if you typed the line
# {
interactively, Tcl would think that the command wasn't complete and
wait for more input before evaluating the script.
235. 10/14/93 Fixed bug where "regsub" didn't set the output variable
if the input string was empty.
236. 10/23/93 Fixed bug where Tcl_CreatePipeline didn't close off enough
file descriptors in child processes, causing children not to exit
properly in some cases.
237. 10/28/93 Changed "list" and "concat" commands not to generate
errors if given zero arguments, but instead to just return an empty
string.
----------------- Released version 7.1, 11/4/93 ------------------
Note: there is no 7.2 release. It was flawed and was thus withdrawn
shortly after it was released.
238. 11/10/93 TclMain.c didn't compile on some systems because of
R_OK in call to "access". Changed to eliminate call to "access".
----------------- Released version 7.3, 11/26/93 ------------------
239. 11/6/93 Modified "lindex", "linsert", "lrange", and "lreplace"
so that "end" can be specified as an index.
240. 11/6/93 Modified "append" and "lappend" to allow only two
words total (i.e., nothing to append) without generating an error.
241. 12/2/93 Changed to use EAGAIN as the errno for non-blocking
I/O instead of EWOULDBLOCK: this should fix problem where non-blocking
I/O didn't work correctly on System-V systems.
242. 12/22/93 Fixed bug in expressions where cancelled evaluation
wasn't always working correctly (e.g. "set one 1; eval {1 || 1/$one}"
failed with a divide by zero error).
243. 1/6/94 Changed TCL_VOLATILE definition from -1 to the address of
a dummy procedure Tcl_Volatile, since -1 causes portability problems on
some machines (e.g., Crays).
244. 2/4/94 Added support for unary plus.
245. 2/17/94 Changed Tcl_RecordAndEval and "history" command to
call Tcl_GlobalEval instead of Tcl_Eval. Otherwise, invocation of
these facilities in nested procedures can cause unwanted results.
246. 2/17/94 Fixed bug in tclExpr.c where an expression such as
"expr {"12398712938788234-1298379" != ""}" triggers an integer
overflow error for the number in quotes, even though it isn't really
a proper integer anyway.
247. 2/19/94 Added new procedure Tcl_DStringGetResult to move result
from interpreter to a dynamic string.
248. 2/19/94 Fixed bug in Tcl_DStringResult that caused it to overwrite
the contents of a static result in some situations. This can cause
bizarre errors such as variables suddenly having empty values.
249. 2/21/94 Fixed bug in Tcl_AppendElement, Tcl_DStringAppendElement,
and the "lappend" command that caused improper omission of a separator
space in some cases. For example, the script
set x "abc{"; lappend x "def"
used to return the result "abc{def" instead of "abc{ def".
250. 3/3/94 Tcl_ConvertElement was outputting empty elements as \0 if
TCL_DONT_USE_BRACES was set. This depends on old pre-7.0 meaning of
\0, which is no longer in effect, so it didn't really work. Changed
to output empty elements as {} always.
251. 3/3/94 Renamed Tcl_DStringTrunc to Tcl_DStringSetLength and extended
it so that it can be used to lengthen a string as well as shorten it.
Tcl_DStringTrunc is defined as a macro for backward compatibility, but
it is deprecated.
252. 3/3/94 Added Tcl_AllowExceptions procedure.
253. 3/13/94 Fixed bug in Tcl_FormatCmd that could cause "format"
to mis-behave on 64-bit Big-Endian machines.
254. 3/13/94 Changed to use vfork instead of fork on systems where
vfork exists.
255. 3/23/94 Fixed bug in expressions where ?: didn't associate
right-to-left as they should.
256. 4/3/94 Fixed "exec" to flush any files used in >@ or >&@
redirection in exec, so that data buffered for them is written
before any new data added by the subprocess.
257. 4/3/94 Added "subst" command.
258. 5/20/94 The tclsh main program is now called Tcl_Main; tclAppInit.c
has a "main" procedure that calls Tcl_Main. This makes it easier to use
Tcl with C++ programs, which need their own main programs, and it also
allows an application to prefilter the argument list before calling
Tcl_Main.
*** POTENTIAL INCOMPATIBILITY ***
259. 6/6/94 Fixed bug in procedure returns where the errorInfo variable
could get truncated if an unset trace was invoked as part of returning
from the procedure.
260. 6/13/94 Added "wordstart" and "wordend" options to "string" command.
261. 6/27/94 Fixed bug in expressions where they didn't properly cancel
the evaluation of math functions in &&, ||, and ?:.
262. 7/11/94 Incorrect boolean values, like "ogle", weren't being
handled properly.
263. 7/15/94 Added Tcl_RegExpCompile, Tcl_RegExpExec, and Tcl_RegExpRange,
which provide lower-level access to regular expression pattern matching.
264. 7/22/94 Fixed bug in "glob" command where "glob -nocomplain ~bad_user"
would complain about a missing user. Now it doesn't complain anymore.
265. 8/4/94 Fixed bug with linked variables where they didn't behave
correctly when accessed via upvars.
266. 8/17/94 Fixed bug in Tcl_EvalFile where it didn't clear interp->result.
267. 8/31/94 Modified "open" command so that errors in exec-ing
subprocesses are returned by the open immediately, rather than
being delayed until the "close" is executed.
268. 9/9/94 Modified "expr" command to generate errors for integer
overflow (includes addition, subtraction, negation, multiplication,
division).
269. 9/23/94 Modified "regsub" to return a count of the number of
matches and replacements, rather than 0/1.
279. 10/4/94 Added new features to "array" command:
- added "get" and "set" commands for easy conversion between arrays
and lists.
- added "exists" command to see if a variable is an array, changed
"names" and "size" commands to treat a non-existent array (or scalar
variable) just like an empty one.
- added pattern option to "names" command.
280. 10/6/94 Modified Tcl_SetVar2 so that read traces on variables get
called during append operations.
281. 10/20/94 Fixed bug in "read" command where reading from stdin
required two control-D's to stop the reading.
282. 11/3/94 Changed "expr" command to use longs for division just like
all other expr operators; it previously used ints for division.
283. 11/4/94 Fixed bugs in "unknown" procedure: it wasn't properly
handling exception returns from commands that were executed after
being auto-loaded.
----------------- Released version 7.4b1, 12/23/94 ------------------
284. 12/26/94 Fixed "install" target in Makefile (couldn't always
find install program).
285. 12/26/94 Added strcncasecmp procedure to compat directory.
286. 1/3/95 Fixed all procedure calls to explicitly cast arguments:
implicit conversions from prototypes (especially integer->double)
don't work when compiling under non-ANSI compilers. Tcl is now clean
under gcc -Wconversion.
287. 1/4/95 Fixed problem in Tcl_ArrayCmd where same name was used for
both a label and a variable; caused problems on several older compilers,
making array command misbehave and causing many errors in Tcl test suite.
----------------- Released version 7.4b2, 1/12/95 ------------------
288. 2/9/95 Modified Tcl_CreateCommand to return a token, and added
Tcl_GetCommandName procedure. Together, these procedures make it possible
to track renames of a command.
289. 2/13/95 Fixed bug in expr where "089" was interpreted as a
floating-point number rather than a bogus octal number.
*** POTENTIAL INCOMPATIBILITY ***
290. 2/14/95 Added code to Tcl_GetInt and Tcl_GetDouble to check for
overflows when reading in numbers.
291. 2/18/95 Changed "array set" to stop after first error, rather than
continuing after error.
292. 2/20/95 Upgraded to use autoconf version 2.2.
293. 2/20/95 Fixed core dump that could occur in "scan" command if a
close bracket was omitted.
294. 2/27/95 Changed Makefile to always use install-sh for installations:
there's just too much variation among "install" system programs, which
makes installation flakey.
----------------- Released version 7.4b3, 3/24/95 ------------------
3/25/95 (bug fix) Changed "install" to "./install" in Makefile so that
"make install" will work even when "." isn't in the search path.
3/29/95 (bug fix) Fixed bug where the auto-loading mechanism wasn't
protecting the values of the errorCode and errorInfo variables.
3/29/95 (new feature) Added optional pattern argument to "parray" procedure.
3/29/95 (bug fix) Made the full functionality of
"return -code ... -errorcode ..."
work not just inside procedures, but also in sourced files and at
top level.
4/6/95 (new feature) Added "pattern" option to "array names" command.
4/18/95 (bug fix) Fixed bug in parser where it didn't allow backslash-newline
immediately after an argument in braces or quotes.
4/19/95 (new feature) Added tcl_library variable, which application can
set to override default library directory.
4/30/95 (bug fix) During trace callbacks for array elements, the variable
name used in the original reference would be temporarily modified to
separate the array name and element name; if the trace callback used
the same name string, it would get the wrong name (the array name without
element). Fixed to restore the variable name before making trace
callbacks.
4/30/95 (new feature) Added -nobackslashes, -nocommands, and -novariables
switches to "subst" command.
5/4/95 (new feature) Added TCL_EVAL_GLOBAL flag to Tcl_RecordAndEval.
5/5/95 (bug fix) Format command would overrun memory when printing
integers with very large precision, as in "format %.1000d 0".
5/5/95 (portability improvement) Changed to use BSDgettimeofday on
IRIX machines, to avoid compilation problems with the gettimeofday
declaration.
5/6/95 (bug fix) Changed manual entries to use the standard .TH
macro instead of a custom .HS macro; the .HS macro confuses index
generators like makewhatis.
5/9/95 (bug fix) Modified configure script to check for Solaris bug
that makes vfork unreliable (core dumps result if vforked child
changes a signal handler); will use fork instead of vfork if the
bug is present.
6/5/95 (bug fix) Modified "lsort" command to disallow recursive calls
to lsort from a comparison function. This is needed because qsort
is not reentrant.
6/5/95 (bug fix) Undid change 243 above: changed TCL_VOLATILE and
TCL_DYNAMIC back to integer constants rather than procedure addresses.
This was needed because procedure addresses can have multiple values
under some dynamic loading systems (e.g. SunOS 4.1 and Windows).
6/8/95 (feature change) Modified interface to Tcl_Main to pass in the
address of the application-specific initialization procedure.
Tcl_AppInit is no longer hardwired into Tcl_Main. This is needed
in order to make Tcl a shared library.
6/8/95 (feature change) Modified Makefile so that the installed versions
of tclsh and libtcl.a have version number in them (e.g. tclsh7.4 and
libtcl7.4.a) and the library directory name also has an embedded version
number (e.g., /usr/local/lib/tcl7.4). This should make it easier for
Tcl 7.4 to coexist with earlier versions.
----------------- Released version 7.4b4, 6/16/95 ------------------
6/19/95 (bug fix) Fixed bugs in tclCkalloc.c that caused core dumps
if TCL_MEM_DEBUG was enabled on word-addressed machines such as Crays.
6/21/95 (feature removal) Removed overflow checks for integer arithmetic:
they just cause too much trouble (e.g. for random number generators).
6/28/95 (new features) Added tcl_patchLevel and tcl_version variables,
for consistency with Tk.
6/29/95 (bug fix) Fixed problem in Tcl_Eval where it didn't record
the right termination character if a script ended with a comment. This
caused erroneous output for the following command, among others:
puts "[
expr 1+1
# duh!
]"
6/29/95 (message change) Changed the error message for ECHILD slightly
to provide a hint about why the problem is occurring.
----------------- Released version 7.4, 7/1/95 ------------------
7/18/95 (bug fix) Changed "lreplace" so that nothing is deleted if
the last index is less than the first index or if the last index
is < 0.
7/18/95 (bug fix) Fixed bugs with backslashes in comments:
Tcl_CommandComplete (and "info complete") didn't properly handle
strings ending in backslash-newline, and neither Tcl_CommandComplete
nor the Tcl parser handled other backslash sequences right, such
as two backslashes before a newline.
7/19/95 (bug fix) Modified Tcl_DeleteCommand to delete the hash table
entry for the command before invoking its callback. This is needed in
order to deal with reentrancy.
7/22/95 (bug fix) "exec" wasn't reaping processes correctly after
certain errors (e.g. if the name of the executable was bogus, as
in "exec foobar").
7/27/95 (bug fix) Makefile.in wasn't using the LIBS variable provided
by the "configure" script. This caused problems on some SCO systems.
7/27/95 (bug fix) The version of strtod in fixstrtod.c didn't properly
handle the case where endPtr == NULL.
----------------- Released patch 7.4p1, 7/29/95 -----------------------
8/4/95 (bug fix) C-level trace callbacks for variables were sometimes
receiving the PART1_NOT_PARSED flag, which could cause errors in
subsequent Tcl library calls using the flags. (JO)
8/4/95 (bug fix) Calls to toupper and tolower weren't using the
UCHAR macros, which caused trouble in non-U.S. locales. (JO)
8/10/95 (new feature) Added the "load" command for dynamic loading of
binary packages, and the Tcl_PackageInitProc prototype for package
initialization procedures. (JO)
8/23/95 (new features) Added "info sharedlibextension" and
"info nameofexecutable" commands, plus Tcl_FindExtension procedure. (JO)
8/25/95 (bug fix) If the target of an "upvar" was non-existent but
had traces set, the traces were silently lost. Change to generate
an error instead. (JO)
8/25/95 (bug fix) Undid change from 7/19, so that commands can stay
around while their deletion callbacks execute. Added lots of code to
handle all of the reentrancy problems that this opens up. (JO)
8/25/95 (bug fix) Fixed core dump that could occur in TclDeleteVars
if there was an upvar from one entry in the table to the next entry
in the same table. (JO)
8/28/95 (bug fix) Exec wasn't handling bad user names properly, as
in "exec ~bogus_user/foo". (JO)
8/29/95 (bug fixes) Changed backslash-newline handling to correct two
problems:
- Only spaces and tabs following the backslash-newline are now
absorbed as part of the backslash-newline. Newlinew are no
longer absorbed (add another backslash if you want to absorb
another newline).
- TclWordEnd returns the character just before the backslash in
the sequence as the end of the sequence; it used to not consider
the backslash-newline as a word separator. (JO)
8/31/95 (new feature) Changed man page installation (with "mkLinks"
script) to create additional links for manual pages corresponding to
each of the procedure and command names described in the pages. (JO)
9/10/95 Reorganized Tcl sources for Windows and Mac ports. All sources
are now in subdirectories: "generic" contains sources that work on all
platforms, "windows", "mac", and "unix" directories contain platform-
specific sources. Some UNIX sources are also used on other platforms. (SS)
9/10/95 (feature change) Eliminated exported global variables (they
don't work with Windows DLLs). Replaced tcl_AsyncReady and
tcl_FileCloseProc with procedures Tcl_AsyncReady() and
Tcl_SetFileCloseProc(). Replaced C variable tcl_RcFileName with
a Tcl variable tcl_rcFileName. (SS)
*** POTENTIAL INCOMPATIBILITY ***
9/11/95 (new feature) Added procedure Tcl_SetPanicProc to override
the default implementation of "panic". (SS)
9/11/95 (new feature) Added "interp" command to allow creation of
new interpreters and execution of untrusted scripts. Added many new
procedures, such as Tcl_CreateSlave, Tcl_CreateAlias,and Tcl_MakeSafe,
to provide C-level access to the interpreter facility. This mechanism
now provides almost all of the generic functions of Borenstein's and
Rose's Safe-Tcl (but not any Tk or email-related stuff). (JL)
9/11/95 (feature change) Changed file management so that files are
no longer shared between interpreters: a file cannot normally be
referenced in one interpreter if it was opened in another. This
feature is needed to support safe interpreters. Added Tcl_ShareHandle()
procedure for allowing files to be shared, and added "interp" argument
to Tcl_FilePermissions procedure. (JL)
*** POTENTIAL INCOMPATIBILITY ***
9/11/95 (new feature) Added "AssocData" mechanism, whereby extensions
can associate their own data with an interpreter and get called back
when the interpreter is deleted. This is visible at C level via the
procedures Tcl_SetAssocData and Tcl_GetAssocData. (JL)
9/11/95 (new feature) Added Tcl_ErrnoMsg to translate an errno value
into a human-readable string. This is now used instead of calling
strerror because strerror mesages vary dramatically from platform
to platform, which messes up Tcl tests. Tcl_ErrnoMsg uses the standard
POSIX messages for all the common signals, and calls strerror for
signals it doesn't understand.
----------------- Released patch 7.4p2, 9/15/95 -----------------------
----------------- Released 7.5a1, 9/15/95 -----------------------
9/22/95 (bug fix) Changed auto_mkindex to create tclIndex files that
handle directories whose paths might contain spaces. (RJ)
9/27/95 (bug fix) The "format" command didn't check for huge or negative
width specifiers, which could cause core dumps. (JO)
9/27/95 (bug fix) Core dumps could occur if an interactive command typed
to tclsh returned a very long result for tclsh to print out. The bug is
actually in printf (in Solaris 2.3 and 2.4, at least); switched to use
puts instead. (JO)
9/28/95 (bug fix) Changed makefile.bc to eliminate a false dependency
for tcl1675.dll on the Borland run time library. (SS)
9/28/95 (bug fix) Fixed tcl75.dll so it looks for tcl1675.dll instead
of tcl16.dll. (SS)
9/28/95 (bug fix) Tcl was not correctly detecting the difference
between Win32s and Windows '95. (SS)
9/28/95 (bug fix) "exec" was not passing environment changes to child
processes under Windows. (SS)
9/28/95 (bug fix) Changed Tcl to ensure that open files are not passed
to child processes under Windows. (SS)
9/28/95 (bug fix) Fixed Windows '95 and NT versions of exec so it can
handle both console and windows apps. (SS)
9/28/95 (bug fix) Fixed Windows version of exec so it no longer leaves
temp files lying around. Also changed it so the temp files are
created in the appropriate system dependent temp directory. (SS)
9/28/95 (bug fix) Eliminated source dependency on the Win32s Universal
Thunk header file, since it is not bundled with VC++. (SS)
9/28/95 (bug fix) Under Windows, Tcl now constructs the HOME
environment variable from HOMEPATH and HOMEDRIVE when HOME is not
already set. (SS)
9/28/95 (bug fix) Added support for "info nameofexecutable" and "info
sharedlibextension" to the Windows version. (SS)
9/28/95 (bug fix) Changed tclsh to correctly parse command line
arguments so that backslashes are preserved under Windows. (SS)
9/29/95 (bug fix) Tcl 7.5a1 treated either return or newline as end
of line in "gets", which caused lines ending in CRLF to be treated as
two separate lines. Changed to allow only character as end-of-line:
carriage return on Macs, newline elsewhere. (JO)
9/29/95 (new feature) Changed to install "configInfo" file in same
directory as library scripts. It didn't used to get installed. (JO)
9/29/95 (bug fix) Tcl was not converting Win32 errors into POSIX
errors under some circumstances. (SS)
10/2/95 (bug fix) Safe interpreters no longer get initialized with
a call to Tcl_Init(). (JL)
10/1/95 (new feature) Added "tcl_platform" global variable to provide
environment information such as the instruction set and operating
system. (JO)
10/1/95 (bug fix) "exec" command wasn't always generating the
"child process exited abnormally" message when it should have. (JO)
10/2/95 (bug fix) Changed "mkLinks.tcl" so that the scripts it generates
won't create links that overwrite original manual entries (there was
a problem where pack-old.n was overwriting pack.n). (JO)
10/2/95 (feature change) Changed to use -ldl for dynamic loading under
Linux if it is available, but fall back to -ldld if it isn't. (JO)
10/2/95 (bug fix) File sharing was causing refcounts to reach 0
prematurely for stdin, stdout and stderr, under some circumstances. (JL)
10/2/95 (platform support) Added support for Visual C++ compiler on
Windows, Windows '95 and Windows NT, code donated by Gordon Chaffee. (JL)
10/3/95 (bug fix) Tcl now frees any libraries that it loads before it
exits. (SS)
10/03/95 (bug fix) Fixed bug in Macintosh ls command where the -l
and -C options would fail in anything but the HOME directory. (RJ)
----------------- Released 7.5a2, 10/6/95 -----------------------
10/10/95 (bug fix) "file dirnam /." was returning ":" on UNIX instead
of "/". (JO)
10/13/95 (bug fix) Eliminated dependency on MKS toolkit for generating
the tcl.def file from Borland object files. (SS)
10/17/95 (new features) Moved the event loop from Tcl to Tk, made major
revisions along the way:
- New Tcl commands: after, update, vwait (replaces "tkwait variable").
- "tkerror" is now replaced with "bgerror".
- The following procedures are similar to their old Tk counterparts:
Tcl_DoOneEvent, Tcl_Sleep, Tcl_DoWhenIdle, Tcl_CancelIdleCall,
Tcl_CreateFileHandler, Tcl_DeleteFileHandler, Tcl_CreateTimerHandler,
Tcl_DeleteTimerHandler, Tcl_BackgroundError.
- Revised notifier, add new concept of "event source" with the following
procedures: Tcl_CreateEventSource, Tcl_DeleteEventSource,
Tcl_WatchFile, Tcl_SetMaxBlockTime, Tcl_FileReady, Tcl_QueueEvent,
Tcl_WaitForEvent. (JO)
10/31/95 (new features) Implemented cross platform file name support to make
it easier to write cross platform scripts. Tcl now understands 4 file naming
conventions: Windows (both DOS and UNC), Mac, Unix, and Network. The network
convention is a new naming mechanism that can be used to paths in a platform
independent fashion. See the "file" command manual page for more details.
The primary interfaces changes are:
- All Tcl commands that expect a file name now accept both network and
native form.
- Two new "file" subcommands, "nativename" and "networkname", provide a
way to convert between network and native form.
- Renamed Tcl_TildeSubst to Tcl_TranslateFileName, and changed it so that
it always returns a filename in native form. Tcl_TildeSubst is defined
as a macro for backward compatibility, but it is deprecated. (SS)
11/5/95 (new feature) Made "tkerror" and "bgerror" synonyms, so that
either name can be used to manipulate the command (provides temporary
backward compatibility for existing scripts that use tkerror). (JO)
11/5/95 (new feature) Added exit handlers and new C procedures
Tcl_CreateExitHandler, Tcl_DeleteExitHandler, and Tcl_Exit. (JO)
11/6/95 (new feature) Added pid command for Macintosh version of
Tcl (it didn't previously exist on the Mac). (RJ)
11/7/95 (new feature) New generic IO facility and support for IO to
files, pipes and sockets based on a common buffering scheme. Support
for asynchronous (non-blocking) IO and for event driver IO. Support
for automatic (background) asynchronous flushing and asynchronous
closing of channels. (JL)
11/7/95 (new feature) Added new commands "fconfigure" and "fblocked"
to support new I/O features such as nonblocking I/O. Added "socket"
command for creating TCP client and server sockets. (JL).
11/7/95 (new feature) Complete set of C APIs to the new generic IO
facility:
- Opening channels: Tcl_OpenFileChannel, Tcl_OpenCommandChannel,
Tcl_OpenTcpClient, Tcl_OpenTcpServer.
- I/O procedures on channels, which roughly mirror the ANSI C stdio
library: Tcl_Read, Tcl_Gets, Tcl_Write, Tcl_Flush, Tcl_Seek,
Tcl_Tell, Tcl_Close, Tcl_Eof, Tcl_InputBlocked, Tcl_GetChannelOption,
Tcl_SetChannelOption.
- Extension mechanism for creating new kinds of channels:
Tcl_CreateChannel, Tcl_GetChannelInstanceData, Tcl_GetChannelType,
Tcl_GetChannelName, Tcl_GetChannelFile, Tcl_RegisterChannel,
Tcl_UnregisterChannel, Tcl_GetChannel.
- Event-driven I/O on channels: Tcl_CreateChannelHandler,
Tcl_DeleteChannelHandler. (JL)
11/7/95 (new feature) Channel driver interface specification to allow
new types of channels to be added easily to Tcl. Currently being used
in three drivers - for files, pipes and TCP-based sockets. (JL).
11/7/95 (new feature) interp delete now takes any number of path
names of interpreters to delete, including zero. (JL).
11/8/95 (new feature) implemented 'info hostname' and Tcl_GetHostName
command to get host name of machine on which the Tcl process is running. (JL)
11/9/95 (new feature) Implemented file APIs for access to low level files
on each system. The APIs are: Tcl_CloseFile, Tcl_OpenFile, Tcl_ReadFile,
Tcl_WriteFile and Tcl_SeekFile. Also implemented Tcl_WaitPid which waits
in a system dependent manner for a child process. (JL)
11/9/95 (new feature) Added Tcl_UpdateLinkedVar procedure to force a
Tcl variable to be updated after its C variable changes. (JO)
11/9/95 (bug fix) The glob command has been totally reimplemented so
that it can support different file name conventions. It now handles
Windows file names (both UNC and drive-relative) properly. It also
supports nested braces correctly now. (SS)
11/13/95 (bug fix) Fixed Makefile.in so that configure can be run
from a clean directory separate from the Tcl source tree, and compilations
can be performed there. (JO)
11/14/95 (bug fix) Fixed file sharing between interpreters and file
transferring between interpreters to correctly manage the refcount so that
files are closed when the last reference to them is discarded. (JL)
11/14/95 (bug fix) Fixed gettimeofday implementation for the
Macintosh. This fixes several timing related bugs. (RJ)
11/17/95 (new feature) Added missing support for info nameofexecutable
on the Macintosh. (RJ)
11/17/95 (bug fix) The Tcl variables argc argv and argv0 now return
something reasonable on the Mac. (RJ)
11/22/95 (new feature) Implemented "auto-detect" mode for end of line
translations. On input, standalone "\r" mean MAC mode, standalone "\n"
mean Unix mode and "\r\n" means Windows mode. On output, the mode is
modified to whatever the platform specific mode for that platform is. (JL)
11/24/95 (feature change) Replaced "configInfo" file with tclConfig.sh,
which is more complete and uses slightly different names. Also
arranged for tclConfig.sh to be installed in the platform-specific
library directory instead of Tcl's script library directory. (JO)
*** POTENTIAL INCOMPATIBILITY with Tcl 7.5a2, but not with Tcl 7.4 ***
----------------- Released patch 7.4p3, 11/28/95 -----------------------
12/5/95 (new feature) Added Tcl_File facility to support platform-
independent file handles. Changed all interfaces that used Unix-
style integer fd's to use Tcl_File's instead. (SS)
*** POTENTIAL INCOMPATIBILITY ***
12/5/95 (new feature) Added a new "clock" command to Tcl. The command
allows you to get the current "clicks" or seconds & allows you to
format or scan human readable time/date strings. (RJ)
12/18/95 (new feature) Moved Tk_Preserve, Tk_Release, and Tk_EventuallyFree
to Tcl, renamed to Tcl_Preserve, Tcl_Release, and Tcl_EventuallyFree. (JO)
12/18/95 (new feature) Added new "package" command and associated
procedures Tcl_PkgRequire and Tcl_PkgProvide. Also wrote
pkg_mkIndex library procedure to create index files from binaries
and scripts. (JO)
12/20/95 (new feature) Added Tcl_WaitForFile procedure. (JO)
12/21/95 (new features) Made package name argument to "load" optional
(Tcl will now attempt to guess the package name if necessary). Also
added Tcl_StaticPackage and support in "load" for statically linked
packages. (JO)
12/22/95 (new feature) Upgraded the foreach command to accept multiple
loop variables and multiple value lists. This lets you iterate over
multiple lists in parallel, and/or assign multiple loop variables from
one value list during each iteration. The only potential compatibility
problem is with scripts that used loop variables with a name that could be
construed to be a list of variable names (i.e. contained spaces). (BW)
1/5/96 (new feature) Changed tclsh so it builds as a console mode
application under Windows. Now tclsh can be used from the command
line with pipes or interactively. Note that this only works under
Windows 95 or NT. (SS)
1/17/96 (new feature) Modified Makefile and configure script to allow
Tcl to be compiled as a shared library: use the --enable-shared option
when configuing. (JO)
1/17/96 (removed obsolete features) Removed the procedures Tcl_EnterFile
and Tcl_GetOpenFile: these no longer make sense with the new I/O system. (JL)
*** POTENTIAL INCOMPATIBILITY ***
1/19/96 (bug fixes) Prevented formation of circular aliases, through the
Tcl 'interp alias' command and through the 'rename' command, as well as
through the C API Tcl_CreateAlias. (JL)
1/19/96 (bug fixes) Fixed several bugs in direct deletion of interpreters
with Tcl_DeleteInterp when the interpreter is a slave; fixes based on a
patch received from Viktor Dukhovni of ESM. (JL)
1/19/96 (new feature) Implemented on-close handlers for channels; added
the C APIs Tcl_CreateCloseHandler and Tcl_DeleteCloseHandler. (JL)
1/19/96 (new feature) Implemented portable error reporting mechanism; added
the C APIs Tcl_SetErrno and Tcl_GetErrno. (JL)
1/24/96 (bug fix) Unknown command processing properly invokes external
commands under Windows NT and Windows '95 now. (SS)
1/23/96 (bug fix) Eliminated extremely long startup times under Windows '95.
The problem was a result of the option database initialization code that
concatenated $HOME with /.Xdefaults, resulting in a // in the middle of the
file name. Under Windows '95, this is incorrectly interpreted as a UNC
path. They delays came from the network timeouts needed to determine that
the file name was invalid. Tcl_TranslateFileName now suppresses duplicate
slashes that aren't at the beginning of the file name. (SS)
1/25/96 (bug fix) Changed exec and open to create children so they are
attached to the application's console if it exists. (SS)
1/31/96 (bug fix) Fixed command line parsing to handle embedded
spaces under Windows. (SS)
----------------- Released 7.5b1, 2/1/96 -----------------------
2/7/96 (bug fix) Fixed off by one error in argument parsing code under
Windows. (SS)
2/7/96 (bug fix) Fixed bugs in VC++ makefile that improperly
initialized the tcl75.dll. Fixed bugs in Borland makefile that caused
build failures under Windows NT. (SS)
2/9/96 (bug fix) Fixed deadlock problem in AUTO end of line translation
mode which would cause a socket server with several concurrent clients
writing in CRLF mode to hang. (JL)
2/9/96 (API change) Replaced -linemode option to fconfigure with a
new -buffering option, added "none" setting to enable immediate write. (JL)
*** INCOMPATIBILITY with b1 ***
2/9/96 (new feature) Added C API Tcl_InputBuffered which returns the count
of bytes currently buffered in the input buffer of a channel, and o for
output only channels. (JL)
2/9/96 (new feature) Implemented asynchronous connect for sockets. (JL)
2/9/96 (new feature) Added C API Tcl_SetDefaultTranslation to set (per
channel) the default end of line translation mode. This is the mode that
will be installed if an output operation is done on the channel while it is
still in AUTO mode. (JL)
2/9/96 (bug fix) Changed Tcl_OpenCommandChannel interface to properly
handle all of the combinations of stdio inheritance in background
pipelines. See the Tcl_OpenFileChannel(3) man page for more
info. This change fixes the bug where exec of a background pipeline
was not getting passed the stdio handles properly. (SS)
2/9/96 (bug fix) Removed the new Tcl_CreatePipeline interface, and
restored the old version for Unix platforms only. All new code should
use Tcl_CreateCommandChannel instead. (SS)
2/9/96 (bug fix) Changed Makefile.in to use -L and -ltcl7.5 for Tcl
library so that shared libraries are more likely to be found correctly
on more platforms. (JO)
2/13/96 (new feature) Added C API Tcl_SetNotifierData and
Tcl_GetNotifierData to allow notifier and channel driver writers to
associate data with a Tcl_File. The result of this change is that
Tcl_GetFileInfo now always returns an OS file handle, and Tcl_GetFile
can be used to construct a Tcl_File for an externally constructed OS
handle. (SS)
2/13/96 (bug fix) Changed Windows socket implementation so it doesn't
set SO_REUSEADDR on server sockets. Now attempts to create a server
socket on a port that is already in use will be properly identified
and an error will be generated. (SS)
2/13/96 (bug fix) Fixed problems with DLL initialization under Visual
C++ that left the C run time library uninitialized. (SS)
2/13/96 (bug fix) Fixed Windows socket initialization so it loads
winsock the first time it is used, rather than at the time tcl75.dll
is loaded. This should fix the bug where the modem immediately starts
trying to connect to a service provider when wish or tclsh are
started. (SS)
2/13/96 (new feature) Added C APIs Tcl_MakeFileChannel and
Tcl_MakeTcpClientChannel to wrap up existing fds and sockets into
channels. Provided implementations on Unix and Windows. (JL)
2/13/96 (bug fix) Fixed bug with seek leaving EOF and BLOCKING set. (JL)
2/14/96 (bug fix) Fixed reentrancy problem in fileevent handling
and made it more robust in the face of errors. (JL)
2/14/96 (feature change) Made generic IO level emulate blocking mode if the
channel driver is unable to provide it, e.g. if the low level device is
always nonblocking. Thus, now blocking behavior is an advisory setting for
channel drivers and can be ignored safely if the channel driver is unable
to provide it. (JL)
2/15/96 (new feature) Added "binary" end of line translation mode, which is
a synonym of "lf" mode. (JL)
2/15/96 (bug fix) Fixed reentrancy problem in fileevent handling vs
deletion of channel event handlers. (JL)
2/15/96 (bug fix) Fixed bug in event handling which would cause a
nonblocking channel to not see further readable events after the first
readable event that had insufficient input. (JL)
2/17/96 (bug fix) "info complete" didn't properly handle comments
in nested commands. (JO)
2/21/96 (bug fix) "exec" under Windows NT/95 did not properly handle
very long command lines (>200 chars). (SS)
2/21/96 (bug fix) Sockets could get into an infinite loop if a read
event arrived after all of the available data had been read. (SS)
2/22/96 (bug fix) Added cast of st_size elements to (long) before
sprintf-ing in "file size" command. This is needed to handle systems
like NetBSD with 64-bit file offsets. (JO)
----------------- Released 7.5b2, 2/23/96 -----------------------
2/23/96 (bug fix) TCL_VARARGS macro in tcl.h wasn't defined properly
when compiling with C++. (JO)
2/24/96 (bug fix) Removed dependencies on Makefile in the UNIX Makefile:
this caused problems on some platforms (like Linux?). (JO)
2/24/96 (bug fix) Fixed configuration bug that made Tcl not compile
correctly on Linux machines with neither -ldl or -ldld. (JO)
2/24/96 (new feature) Added a block of comments and definitions to
Makefile.in to make it easier to have Tcl's TclSetEnv etc. replace
the library procedures setenv etc, so that calls to setenv etc. in
the application automatically update the Tcl "env" variable. (JO)
2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
to C API Tcl_Close and simplified closing of command channels. (JL)
*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
2/27/96 (feature change) Added optional Tcl_Interp * argument (may be NULL)
to C type definition Tcl_DriverCloseProc; modified all channel drivers to
implement close procedures that accept the additional argument. (JL)
*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
2/28/96 (bug fix) Fixed memory leak that could occur if an upvar
referred to an element of an array in the same stack frame as the
upvar. (JO)
2/29/96 (feature change) Modified both Tcl_DoOneEvent and Tcl_WaitForEvent
so that they return immediately in cases where they would otherwise
block forever (e.g. if there are no event handlers of any sort). (JO)
2/29/96 (new feature) Added C APIs Tcl_GetChannelBufferSize and
Tcl_SetChannelBufferSize to set and retrieve the size, in bytes, for
buffers allocated to store input or output in a channel. (JL)
2/29/96 (new feature) Added option -buffersize to Tcl fconfigure command
to allow Tcl scripts to query and set the size of channel buffers. (JL)
2/29/96 (feature removed) Removed channel driver function to specify
the buffer size to use when allocating a buffer. Removed the C typedef
for Tcl_DriverBufferSizeProc. Channels are now created with a default
buffer size of 4K. (JL)
*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
2/29/96 (feature change) The channel driver function for setting blocking
mode on the device may now be NULL. If the generic code detects that the
function is NULL, operations that set the blocking mode on the channel
simply succeed. (JL)
3/2/96 (bug fix) Fixed core dump that could occur if a syntax error
(such as missing close paren) occurred in an array reference with a
very long array name. (JO)
3/4/96 (bug fix) Removed code in the "auto_load" procedure that deletes
all existing auto-load information whenever the "auto_path" variable
is changed. Instead, new information adds to what was already there.
Otherwise, changing the "auto_path" variable causes all package-
related information to be lost. If you really want to get rid of
existing auto-load information, use auto_reset before setting auto_path. (JO)
3/5/96 (new feature) Added version suffix to shared library names so that
Tcl will compile under NetBSD and FreeBSD (I hope). (JO)
3/6/96 (bug fix) Cleaned up error messages in new I/O system to correspond
more closely to old I/O system. (JO)
3/6/96 (new feature) Added -myaddr and -myport options to the socket
command, removed -tcp and -- options. This lets clients and servers
choose a particular interface. Also changed the default server address
from the hostname to INADDR_ANY. The server accept callback now gets
passed the client's port as well as IP address. The C interfaces for
Tcl_OpenTcpClient and Tcl_OpenTcpServer have changed to support the
above changes. (BW)
*** POTENTIAL INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
3/6/96 (changed feature) The library function auto_mkindex will now
default to using the pattern "*.tcl" if no pattern is given. (RJ)
3/6/96 (bug fix) The socket channel code for the Macintosh has been
rewritten to use native MacTcp. (RJ)
3/7/96 (new feature) Added Tcl_SetStdChannel and Tcl_GetStdChannel
interfaces to allow applications to explicitly set and get the global
standard channels. (SS)
3/7/96 (bug fix) Tcl did close not the file descriptors associated
with "stdout", etc. when the corresponding channels were closed. (SS)
3/7/96 (bug fix) Reworked shared library and dynamic loading stuff to
try to get it working under AIX. Added new @SHLIB_LD_LIBS@ autoconf
symbol as part of this. AIX probably doesn't work yet, but it should
be a lot closer. (JO)
3/7/96 (feature change) Added Tcl_ChannelProc typedef and changed the
signature of Tcl_CreateChannelHandler and Tcl_DeleteChannelHandler to take
Tcl_ChannelProc arguments instead of Tcl_FileProc arguments. This change
should not affect any code outside Tcl because the signatures of
Tcl_ChannelProc and Tcl_FileProc are compatible. (JL)
3/7/96 (API change) Modified signature of Tcl_GetChannelOption to return
an int instead of char *, and to take a Tcl_DString * argument. Modified
the implementation so that the option name can be NULL, to mean that the
call should retrieve a list of alternating option names and values. (JL)
*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
3/7/96 (API change) Added Tcl_DriverSetOptionProc, Tcl_DriverGetOptionProc
typedefs, added two slots setOptionProc and getOptionProc to the channel
type structure. These may be NULL to indicate that the channel type does
not support any options. (JL)
*** INCOMPATIBILITY with Tcl 7.5b2, but not with Tcl 7.4 ***
3/7/96 (feature change) stdin, stdout and stderr can now be put into
nonblocking mode. (JL)
3/8/96 (feature change) Eliminated dependence on the registry for
finding the Tcl library files. (SS)
----------------- Released 7.5b3, 3/8/96 -----------------------
3/12/96 (feature improvement) Modified startup script to look in several
different places for the Tcl library directory. This should allow Tcl
to find the libraries under all but the weirdest conditions, even without
the TCL_LIBRARY environment variable being set. (JO)
3/13/96 (bug fix) Eliminated use of the "linger" option from the Windows
socket implementation. (JL)
3/13/96 (new feature) Added -peername and -sockname options for fconfigure
for socket channels. Code contributed by John Haxby of HP. (JL)
3/13/96 (bug fix) Fixed panic and core dump that would occur if the accept
callback script on a server socket encountered an error. (JL)
3/13/96 (feature change) Added -async option to the Tcl socket command.
If the command is creating a client socket and the flag is present, the
client is connected asynchronously. If the option is absent (the default),
the client socket is connected synchronously, and the command returns only
when the connection has been completed or failed. This change was suggested
by Mark Diekhans. (JL)
3/13/96 (feature change) Modified the signature of Tcl_OpenTcpClient to
take an additional int argument, async. If nonzero, the client is connected
to the server asynchronously. If the value is zero, the connection is made
synchronously, and the call to Tcl_OpenTcpClient returns only when the
connection fails or succeeds. This change was suggested by Mark Diekhans. (JL)
*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
3/14/96 (bug fix) "tclsh bogus_file_name" didn't print an error message. (JO)
3/14/96 (bug fix) Added new procedures to tclCkalloc.c so that libraries
and applications can be compiled with TCL_MEM_DEBUG even if Tcl isn't
(however, the converse is still not true). Patches provided by Jan
Nijtmans. (JO)
3/15/96 (bug fix) Marked standard IO handles of a process as close-on-exec
to fix bug in Ultrix where exec was not sharing standard IO handles with
subprocesses. Fix suggested by Mark Diekhans. (JL)
3/15/96 (bug fix) Fixed asynchronous close mechanism so that it closes the
channel instead of leaking system resources. The manifestation was that Tcl
would eventually run out of file descriptors if it was handling a large
number of nonblocking sockets or pipes with high congestion. (JL)
3/15/96 (bug fix) Fixed tests so that they no longer leak file descriptors.
The manifestation was that Tcl would eventually run out of file descriptors
if the tests were rerun many times (> a hundred times on Solaris). (JL)
3/15/96 (bug fix) Fixed channel creation code so that it never creates
unnamed channels. This would cause a panic and core dump when the channel
was closed. (JL)
3/16/96 (bug fixes) Made lots of changes in configuration stuff to get
Tcl working under AIX (finally). Tcl should now support the "load"
command under AIX and should work either with or without shared
libraries for Tcl and Tk. (JO)
3/21/96 (configuration improvement) Changed configure script so it
doesn't use version numbers (as in -ltcl7.5 and libtcl7.5.so) under
SunOS 4.1, where they don't work anyway. (JO)
3/22/96 (new feature) Added C API Tcl_InterpDeleted that allows extension
writers to discover when an interpreter is being deleted. (JL)
3/22/96 (bug fix) The standard IO channels are now added to each
trusted interpreter as soon as the interpreter is created. This ensures
against the bug where a child would do IO before the master had done any,
and then the child is destroyed - the standard IO channels would be then
closed and the master would be unable to do any IO. (JL)
3/22/96 (bug fix) Made Tcl more robust against interpreter deletion, by
using Tcl_Preserve, Tcl_Release and Tcl_EventuallyFree to split the process
of interpreter deletion into two distinct phases. Also went through all of
Tcl and added calls to Tcl_Preserve and Tcl_Delete where needed. (JL)
3/22/96 (bug fix) Fixed several places where C code was reading and writing
into freed memory, especially during interpreter deletion. (JL)
3/22/96 (bug fix) Fixed very deep bug in Tcl_Release that caused memory to
be freed twice if the release callback did Tcl_Preserve and Tcl_Release on
the same memory as the chunk currently being freed. (JL)
3/22/96 (bug fix) Removed several memory leaks that would cause memory
buildup on half-K chunks in the generic IO level. (JL)
3/22/96 (bug fix) Fixed several core dumps which occurred when new
AssocData was being created during the cleanups in interpreter deletion.
The solution implemented now is to loop repeatedly over the AssocData until
none is left to clean up. (JL)
3/22/96 (bug fix) Fixed a bug in event handling which caused an infinite
loop if there were no files being watched and no timer. Fix suggested by
Jan Nijtmans. (JL)
3/22/96 (bug fix) Fixed Tcl_CreateCommand, Tcl_DeleteCommand to be more
robust if the interpreter is being deleted. Also fixed several order
dependency bugs in Tcl_DeleteCommand which kicked in when an interpreter
was being deleted. (JL)
3/26/96 (bug fix) Upon a "short read", the generic code no longer calls
the driver for more input. Doing this caused blocking on some platforms
even on nonblocking channels. Bug and fix courtesy Mark Roseman. (JL)
3/26/96 (new feature) Added 'package Tcltest' which is present only in
test versions of Tcl; this allows the testing commands to be loaded into
new interpreters besides the main one. (JL)
3/26/96 (restored feature) Recreated the Tcl_GetOpenFile C API. You can
now get a FILE * from a registered channel; Unix only. (JL)
3/27/96 (bug fix) The regular expression code did not support more
than 9 subexpressions. It now supports up to 20. (SS)
4/1/96 (bug fixes) The CHANNEL_BLOCKED bit was being left on on a short
read, so that fileevents wouldn't fire correctly. Bug reported by Mark
Roseman.(JL, RJ)
4/1/96 (bug fix) Moved Tcl_Release to match Tcl_Preserve exactly, in
tclInterp.c; previously interpreters were being freed only conditionally
and sometimes not at all. (JL)
4/1/96 (bug fix) Fixed error reporting in slave interpreters when the
error message was being generated directly by C code. Fix suggested by
Viktor Dukhovni of ESM. (JL)
4/2/96 (bug fixes) Fixed a series of bugs in Windows sockets that caused
events to variously get lost, to get sent multiple times, or to be ignored
by the driver. The manifestation was blocking if the channel is blocking,
and either getting EAGAIN or infinite loops if the channel is nonblocking.
This series of bugs was found by Ian Wallis of Cisco. Now all tests (also
those that were previously commented out) in socket.test pass. (JL, SS)
4/2/96 (feature change/bug fix) Eliminated network name support in
favor of better native name support. Added "file split", "file join",
and "file pathtype" commands. See the "file" man page for more
details. (SS)
*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
4/2/96 (bug fix) Changed implementation of auto_mkindex so tclIndex
files will properly handle path names in a cross platform context. (SS)
4/5/96 (bug fix) Fixed Tcl_ReadCmd to use the channel buffer size as the
chunk size it reads, instead of a fixed 4K size. Thus, on large reads, the
user can set the channel buffer size to a large size and the read will
occur orders of magnitude faster. For example, on a 2MB file, reading in 4K
chunks took 34 seconds, while reading in 1MB chunks took 1.5 seconds (on a
SS-20). Problem identified and fix suggested by John Haxby of HP. (JL)
4/5/96 (bug fix) Fixed socket creation code to invoke gethostbyname only if
inet_addr failed (very unlikely). Before this change the order was reversed
and this made things much slower than they needed to be (gethostbyname
generally requires an RPC, which is slow). Problem identified and fix
suggested by John Loverso of OSF. (JL)
4/9/96 (feature change) Modified "auto" translation mode so that it
recognizes any of "\n", "\r" and "\r\n" in input as end of line, so
that a file can have mixed end-of-line sequences. It now outputs
the platform specific end of line sequence on each platform for files and
pipes, and for sockets it produces crlf in output on all platforms. (JL)
*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
4/11/96 (new feature) Added -eofchar option to Tcl_SetChannelOption to allow
setting of an end of file character for input and output. If an input eof
char is set, it is recognized as EOF and further input from the channel is
not presented to the caller. If an output eof char is set, on output, that
byte is appended to the channel when it is closed. On Unix and Macintosh,
all channels start with no eof char set for input or output. On Windows,
files and pipes start with input and output eof chars set to Crlt-Z (ascii
26), and sockets start with no input or output eof char. (JL)
*** INCOMPATIBILITY with Tcl 7.5b3, but not with Tcl 7.4 ***
4/17/96 (bug fix) Fixed series of bugs with handling of crlf sequence split
across buffer boundaries in input, in AUTO mode. (JL, BW)
4/17/96 (test suite improvement) Fixed test suite so that tests that
depend on the availability of Unix commands such as echo, cat and others
are not run if these commands are not present. (JL)
4/17/96 (test suite improvement) The socket test now automatically starts,
on platformst that support exec, a separate process for remote testsing. (JL)
----------------- Released 7.5, 4/21/96 -----------------------
5/1/96 (bug fix) "file tail ~" did not correctly return the tail
portion of the user's home directory. (SS)
5/1/96 (bug fix) Fixed bug in TclGetEnv where it didn't lookup environment
variables correctly: could confuse "H" and "HOME", for example. (JO)
5/1/96 (bug fix) Changed to install tclConfig.sh under "make install-binaries",
not "make install-libraries". (JO)
5/2/96 (bug fix) Changed pkg_mkIndex not to attempt to "load" a file unless
it has the standard shared library extension. On SunOS, attempts to load
Tcl scripts cause the whole application to be aborted (there's no way to
get the error back into Tcl). (JO)
5/7/96 (bug fix) Moved initScript in tclUnixInit.c to writable memory to
avoid potential core dumps. (JO)
5/7/96 (bug fix) Auto_reset procedure was removing procedure from init.tcl,
such as pkg_mkIndex. (JO)
5/7/96 (bug fix) Fixed cast on socket address resolution code that
would cause a failure to connect on Dec Alphas. (JL)
5/7/96 (bug fix) Added "time", "subst" and "fileevent" commands to set of
commands available in a safe interpreter. (JL)
5/13/96 (bug fix) Preventing OS level handles for stdin, stdout and stderr
from being implicitly closed when the last reference to the standard
channel containing that handle is discarded when an interpreter is deleted.
Explicitly closing standard channels by using "close" still works. (JL)
5/21/96 (bug fix) Do not create channels for stdin, stdout and stderr on
Unix if the devices are closed. This prevents a duplicate channel name
panic later on when the fd is used to open a channel and the channel is
registered in an interpreter. (JL)
5/23/96 (bug fix) Fixed bug that prevented the use of standard channels in
interpreters created after the last interpreter was destroyed. In the sequence
interp = Tcl_CreateInterp();
Tcl_DeleteInterp(interp);
interp = Tcl_CreateInterp();
channels for stdio would not be available in the second interpreter. (JL)
5/23/96 (bug fix) Fixed bug that allowed Tcl_MakeFileChannel to create new
channels with Tcl_Files in them that are already used by another channel.
This would cause core dumps when the Tcl_Files were being freed twice. (JL)
5/23/96 (bug fix) Fixed a logical timing bug that caused a standard channel
to be removed from the standard channel table too early when the channel
was being closed. If the channel was being flushed asynchronously, it could
get recreated before being actually destroyed, and the recreated channel
would contain the same Tcl_File as the one being closed, leading to
dangling pointers and core dumps. (JL)
5/27/96 (bug fix) Fixed a bug in Tcl_GetChannelOption which caused it to
always return a list of one element, a list of the settings, for
-translation and -eofchar options. Now correctly returns the value
described by the documentation (Mark Diekhans found this, thanks!). (JL)
5/30/96 (bug fix) Fixed a couple of syntax errors in io.test. (JL)
5/30/96 (bug fix) If a fileevent scripts gets an error, delete it before
causing a background error. This is to allow the error handler to reinstall
the fileevent and to prevent infinite loops if the event loop is reentered
in the error handler. (JL)
5/31/96 (bug fix) Channels now will get properly flushed on exit. (JL)
6/5/96 (bug fix) Changed Tcl_Ckalloc, Tcl_Ckfree, and Tcl_Ckrealloc to
Tcl_Alloc, Tcl_Free, and Tcl_Realloc. Added documentation for these
routines now that they are officially supported. Extension writers
should use these routines instead of free() and malloc(). (SS)
6/10/96 (bug fix) Changes the Tcl close command so that it no longer
waits on nonblocking pipes for the piped processes to exit; instead it
reaps them in the background. (JL)
6/11/96 (bug fix) Increased the length of the listen queue for server
sockets on Unix from 5 to 100. Some OSes will disregard this and reset it
to 5, but we should try to get as long a queue as we can, for performance
reasons. (JL)
6/11/96 (bug fix) Fixed windows sockets bug that caused a cascade of events
if the fileevent script read less than was available. Now reading less than
is available does not cause a flood of Tcl events. (JL, SS)
6/11/96 (bug fix) Fixed bug in background flushing on closed channels that
would prevent the last buffer from getting flushed. (JL)
6/13/96 (bug fix) Fixed bug in Windows sockets that caused a core dump if
a DLL linked with tcl.dll and referred to e.g. ntohs() without opening a
Tcl socket. The problem was that the indirection table was not being
initialized. (JL)
6/13/96 (bug fix) Fixed OS level resource leak that would occur when a
Tcl channel was still registered in some interpreter when the process
exits. Previously the channel was not being closed and the OS level handles
were not being released; the output was being flushed but the device was
not being closed. Now the device is properly closed. This was only a
problem on Win3.1 and MacOS. (JL, SS)
6/28/96 (bug fix) Fixed bug where transient errors were leaving an error
code around, so that it would erroneously get reported later. This bug was
exercised intermittently by closing a channel to a file on a very loaded
NFS server, or to a socket whose other end blocked. (JL, BW)
7/3/96 (bug fix) Fileevents declared in an interpreter are now deleted
when the channel is closed in that interpreter. Before this fix, the
fileevent would hang around until the channel is completely closed, and
would cause errors if events happened before the channel was closed. This
could happen in two cases: first if the channel is shared between several
interpreters, and second if an async flush is in progress that prevents the
channel from being closed until the flush finishes. (JL)
7/10/96 (bug fix) Fixed bugs in both "lrange" and "lreplace" commands
where too much white space was being removed. For example, the command
lreplace {\}\ hello} end end
was returning "\}\", losing the significant space in the first list
element and corrupting the list. (JO)
7/20/96 (bug fix) The procedure pkg_mkIndex didn't work properly for
extensions that depend on Tk, because it didn't load Tk into the child
interpreter before loading the extension. Now it loads Tk if Tk is
present in the parent. (JO)
7/23/96 (bug fix) Added compat version of strftime to fix crashes
resulting from bad implementations under Windows. (SS)
7/23/96 (bug fix) Standard implementations of gmtime() and localtime()
under Windows did not handle dates before 1970, so they were replaced
with a revised implementation. (SS)
7/23/96 (bug fix) Tcl would crash on exit under Borland 5.0 because
the global environ pointer was left pointing to freed memory. (SS)
7/29/96 (bug fix) Fixed memory leak in Tcl_LoadCmd that could occur if
a package's AppInit procedure called Tcl_StaticPackage to register
static packages. (JO)
8/1/96 (bug fix) Fixed a series of bugs in Windows sockets so that async
writebehind in the presence of read event handlers now works, and so that
async writebehind also works on sockets for which a read event handler was
declared and whose channels were then closed before the async write
finished. The bug was reported by John Loverso and Steven Wahl,
independently, test case supplied by John Loverso. (JL)
----------------- Released patch 7.5p1, 8/2/96 -----------------------
5/8/96 (new feature) Added Tcl_GetChannelMode C API for retrieving whether
a channel is open for reading and writing. (JL)
5/8/96 (API changes) Revised C APIs for channel drivers:
- Removed all Tcl_Files from channel driver interface; you can now have
channels that are not based on Tcl_Files.
- Added channelReadyProc and watchChannelProc procedures to interface;
these are used to implement event notification for channels.
- Added getFileProc to channel driver, to allow the generic IO code
to retrieve a Tcl_File from a channel (presumably if the channel
uses Tcl_Files they will be stored inside its instanceData). (JL)
*** INCOMPATIBILITY with Tcl 7.5 ***
5/8/96 (API change) The Tcl_CreateChannel C API was modified to not take
Tcl_File arguments, and instead to take a mask specifying whether the
channel is readable and/or writable. (JL)
*** INCOMPATIBILITY with Tcl 7.5 ***
6/3/96 (bug fix) Made Tcl_SetVar2 robust against the case where the value
of the variable is a NULL pointer instead of "". (JL)
6/17/96 (bug fix) Fixed "reading uninitialized memory" error reported by
Purify, in Tcl_Preserve/Tcl_Release. (JL)
8/9/96 (bug fix) Fixed bug in init.tcl that caused incorrect error message
if the act of autoloading a procedure caused the procedure to be invoked
again. (JO)
8/9/96 (bug fix) Configure script produced bad library names and extensions
under SunOS and a few other platforms if the --disable-load switch was used.
(JO)
8/9/96 (bug fix) Tcl_UpdateLinkedVar generated an error if the variable
being updated was read-only. (JO)
8/14/96 (bug fix) The macintosh now supports synchronous socket
connections. Other minor bugs were also fixed. (RJ)
8/15/96 (configuration improvement) Changed the file patchlevel.h
to be tclPatch.h. This avoids conflict with the Tk file and is now
in 8.3 format on the Windows platform. (RJ)
8/20/96 (bug fix) Fixed core dump in interp alias command for interpreters
created with Tcl_CreateInterp (as opposed to with Tcl_CreateSlave). (JL)
8/20/96 (bug fix) No longer masking ECONNRESET on Windows sockets so
that the higher level of the IO mechanism sees the error instead of
entering an infinite loop. (JL)
8/20/96 (bug fix) Destroying the last interpreter no longer closes the
standard channels. (JL)
8/20/96 (bug fix) Closing one of the stdin, stdout or stderr channels and
then opening a new channel now correctly assigns the new channel as the
standard channel that was closed. (JL)
8/20/96 (bug fix) Added code to unix/tclUnixChan.c for using ioctl with
FIONBIO instead of fcntl with O_NONBLOCK, for those versions of Unix where
either O_NONBLOCK is not supported or implemented incorrectly. (JL)
8/21/96 (bug fix) Fixed "file extension" so it correctly returns the
extension on files like "foo..c" as "..c" instead of ".c". (SS)
8/22/96 (bug fix) If environ[] contains static strings, Tcl would core
dump in TclSetupEnv because it was trying to write NULLs into the actual
data in environ[]. Now we instead copy as appropriate. (JL)
8/22/96 (added impl) Added missing implementation of Tcl_MakeTcpClientChannel
for Windows platform. Code contributed by Mark Diekhans. (JL)
8/22/96 (new feature) Added a new memory allocator for the Macintosh
version of Tcl. It's quite a bit faster than MetroWerk's version. (RJ)
8/26/96 (documentation update) Removed old change bars (for all changes
in Tcl 7.5 and earlier releases) from manual entries. (JO)
8/27/96 (enhancement) The exec and open commands behave better and work in
more situations under Windows NT and Windows 95. Documentation describes
what is still lacking. (CS)
8/27/96 (enhancement) The Windows makefiles will now compile even if the
compiler is not in the path and/or the compiler's environment variables
have not been set up. (CS)
8/27/96 (configuration improvement) The Windows resource files are
automatically updated when the version/patch level changes. The header file
now has a comment that reminds the user which other files must be manually
updated when the version/patch level changes. (CS)
8/28/96 (new feature) Added file manipulation features (copy, rename, delete,
mkdir) that are supported on all platforms. They are implemented as
subcommands to the "file" command. See the documentation for the "file"
command for more information. (JH)
----------------- Released 7.6b1, 8/30/96 -----------------------
9/3/96 (bug fix) Simplified code so that standard channels are created
lazily, they are added to an interpreter lazily, and they are never added
to a safe interpreter. (JL)
9/3/96 (bug fix) Closing a channel after closing a standard channel, e.g.
stdout, would cause the implicit recreation of that standard channel. (JL)
9/3/96 (new feature) Now calling Tcl_RegisterChannel with a NULL
interpreter increments the refcount so that code outside any interpreter
can use channels that are also registered in interpreters, without worrying
that the channel may turn into a dangling pointer at any time. Calling
Tcl_UnregisterChannel with a NULL interpreter only decrements the recount
so that code outside any interpreter can safely declare it is no longer
interested in a channel. (JL)
9/4/96 (new features) Two changes to dynamic loading:
- If the file name is empty in the "load" command and there is no
statically loaded version of the package, a dynamically loaded
version will be used if there is one.
- Tcl_StaticPackage ignores redundant calls for the same package. (JO)
9/6/96 (bug fix) Platform specific procedures for manipulating files are
no longer macros and have been prefixed with "Tclp", such as TclpRenameFile.
Unix file code now handles symbolic links and other special files correctly.
The semantics of file copy and file rename has been changed so that if
a target directory exists, the source files will NOT be merged with the
existing files. (JH)
9/6/96 (bug fix) If standard channel is NULL, because Tcl cannot connect
to the standard channel, do not increment the refcount. The channel can
be NULL if there is for example no standard input. (JL)
9/6/96 (portability improvement) Changed parsing of backslash sequences
like \n to translate directly to absolute values like 0xA instead of
letting the compiler do the translation. This guarantees that the
translation is done the same everywhere. (JO)
9/9/96 (bug fix) If channel is opened and not associated with any
interpreter, but Tcl decides to use it as one of the standard channels, it
became impossible to close the channel with Tcl_Close -- instead you had
to call Tcl_UnregisterChannel. Fixed now so that it's safe to call
Tcl_Close even when Tcl is using the channel as one of the standard ones. (JL)
9/11/96 (feature change) The Tcl library is now placed in the Tcl
shared libraries resource. You no longer need to place the Tcl files
in your applications explicitly. (RJ)
9/11/96 (feature change) Extensions no longer automatically have the
resource fork of the extension opened for it. Instead you need to
use the tclMacLibrary.c file in your extension. (RJ)
*** POTENTIAL INCOMPATIBILITY ***
9/12/96 (bug fix) The extension loading mechanism on the Macintosh now
looks at the 'cfrg' resource to determine where to load the code
fragment from. This means FAT fragments should now work. (RJ)
9/18/96 (enhancement) The exec and open commands behave better and work in
more situations under Windows 3.X. Documentation describes what is still
lacking. (CS)
9/19/96 (bug fix) Fixed a panic which would occur if you delete a
non-existent alias before any aliases are created. Now instead correctly
returns an error that the alias is not found. (JL)
9/19/96 (bug fix) Slave interpreters could rename aliases and they would
not get deleted when the alias was being redefined. This led to dangling
pointers etc. (JL)
9/19/96 (bug fix) Fixed a panic where a hash table entry was being deleted
twice during alias management operations. (JL)
9/19/96 (bug fix) Fixed bug in event loop that could cause the input focus
in Tk to get confused during menu traversal, among other problems. The
problem was related to handling of the "marker" when its event was
deleted. (JO)
9/26/96 (bug fix) Windows was losing EOF on a socket if the FD_CLOSE event
happened to precede any left over FD_READ events. Now correctly remembers
seeing FD_CLOSE, so that trailing FD_READ events are not discarded if they
do not contain any data. This allows Tcl to correctly get a zero read and
notice EOF. (JL)
9/26/96 (bug fix) Was not resetting READABLE state properly on sockets
under Windows if the driver discarded an FD_READ event because no data was
present. Now correctly resets the state. (JL)
9/30/96 (bug fix) Made EOF sticky on Windows sockets, so that fileevent
readable will fire repeatedly until the socket is closed. Previously the
fileevent fired only once. This could lead to never-closed connections if
the Tcl script in the fileevent wasn't closing the socket immediately. (JL)
10/2/96 (new feature) Improved the package loader:
- Added new variable tcl_pkgPath, which holds the default
directories under which packages are normally installed (each
package goes in a separate subdirectory of a directory in
$tcl_pkgPath). These directories are included in auto_path by
default.
- Changed the package auto-loader to look for pkgIndex.tcl files
not only in the auto_path directories but also in their immediate
children. This should make it easier to install and uninstall
packages (don't have to change auto_path or merge pkgIndex.tcl
files). (JO)
10/3/96 (bug fix) Changed tclsh to look for tclshrc.tcl instead of
tclsh.rc on startup under Windows. This is more consistent with wish and
uses the right extension. (SS)
*** POTENTIAL INCOMPATIBILITY ***
10/8/96 (bug fix) Convertclock does not parse 24-hour times of the
form "hhmm" correctly when hour = 00. In the parse code, hour must be
>= 100 for minutes to be non-zero. Thanks to Lint LaCour for this
bug fix. (RJ)
10/11/96 (bug fix) Under Windows, the pid command returned the process
handle instead of the process id. (SS)
----------------- Released 7.6, 10/16/96 -----------------------
10/29/96 (bug fix) Under Windows, sockets would consume 100% CPU time after
the first accept(), due to a typo. (JL)
10/29/96 (bug fix) Incorrect refcount management caused standard channels
not to get deleted at process exit or DLL unload time, causing a memory
leak of upwards of 20K each time. (JL)
11/7/96 (bug fix) Auto-exec didn't work on file names that contained
spaces. (JO)
11/8/96 (bug fix) Fixed core dump that would occur if more than one call
to Tcl_DeleteChannelHandler was made to delete a given channel handler. (JL)
11/8/96 (bug fix) Fixed test for return value in Tcl_Seek and Tcl_SeekCmd
to only treat -1 as error, instead of all negative numbers. (JL)
11/12/96 (bug fix) Do not blocking waiting for processes at the end of a
pipe during exit cleanup. (JL)
11/12/96 (bug fix) If we are in exit cleanup, do not close the system level
file descriptors 0, 1 and 2. Previously they were being closed which is
incorrect, in the embedded case. This led to weird behavior for programs
that want to interpose on I/O through the standard file descriptors (e.g.
Netscape Navigator). (JL)
11/15/96 (bug fix) Fixed core dump on Windows sockets due to dependency on
deletion order at exit. Now all socket functions check to see if sockets
are (still) initialized, before calling through function pointers. Before,
they would call and might end up calling unloaded object code. (JL)
11/15/96 (bug fix) Fixed core dump in Windows socket initialization routine
if sockets were not installed on the system. Before, it was not properly
checking the result of attempting to load the socket DLL, so it would call
through uninitialized function pointers. (JL)
11/15/96 (bug fix) Fixed memory leak in Windows sockets which left socket
DLL handle open and could hold the socket DLL in memory uneccessarily,
until a reboot. (JL)
12/4/96 (bug fix) Fixed bug in Macintosh socket code that could result
in lost data if a client was closed too soon after sending data. (RJ)
12/17/96 (bug fix) Fixed deadlock bug in Windows sockets due to losing an
event. This was happening because of an interaction between buffering and
nonblocking mode on sockets. Now switched to sockets being blocking by
default, so we are also no longer emulating blocking through a private
event loop. (JL)
1/21/97 (performance bug fix) Client TCP connections were slow to create
because getservbyname was always called on the port. Now this is only
done if Tcl_GetInt fails. (BW)
1/21/97 (configuration fix) Made it possible to override TCL_PACKAGE_PATH
during make. Previously it was only set during autoconf process.
1/29/97 (bug fix) Fixed some problems with the clock command that
impacted how dates were scaned after the year 2000. (RJ)
----------------- Released 7.6p2, 1/31/97 -----------------------
2/5/97 (bug fix) Fixed a bug where in CR-LF translation mode, \r bytes
in the input stream were not being handled correctly. (JL)
2/24/97 (bug fix) Fix bug with exec under Win32s not being able to create
stderr file which caused all execs to fail. Fixed temp file leak under
Win32s. Fixed optional parameter bug with SearchPath that only happened
under Win32s 1.25. (CCS)
----------------------------------------------------------
Changes for Tcl 7.6 go above this line.
Changes for Tcl 7.7 go below this line.
----------------------------------------------------------
5/8/96 (new feature) Added Tcl_Ungets C API for putting a sequence of bytes
into a channel's input buffer. This can be used for "push" model channels
where the input is obtained via callbacks instead of by request of the
generic IO code. No Tcl procedure yet. (JL)
11/15/96 (new feature) Implemented hidden commands. New C APIs:
Tcl_HideCommand -- hides an existing exposed command.
Tcl_ExposeCommand -- exposes an existing hidden command.
New tcl APIs:
interp invokehidden -- invokes a hidden command in a slave.
interp hide -- hides an existing exposed command.
interp expose -- exposes an existing hidden command.
interp hidden -- returns a list of hidden commands.
The implementation of Safe Tcl now uses the new hidden commands facility
to implement the safe base, instead of deleting the commands from a safe
interpreter. (JL)
11/15/96 (new feature) Implemented the safe base, a mechanism for
installing and requesting security policies, purely in Tcl code. Overloads
the package command to also allow an interpreter to "require" a policy. The
following new library commands are provided:
tcl_safeCreateInterp -- creates a slave an initializes the
policy mechanism.
tcl_safeInitInterp -- initializes an existing slave with the
policy mechanism.
tcl_safeDeleteInterp -- deletes a slave and deinitializes the
policy mechanism.
Added a new file to the library, safeinit.tcl, to hold implementation. (JL)
On 7/9/97, removed the policy loading mechanism from the Safe Base. Left
only the Safe Base aliases dealing with auto-loading and source. (JL)
12/6/96 (new feature) Implemented Tcl_Finalize, an API that should be
called by a process when it is done using Tcl. This API runs all the exit
handlers to allow them to clean up resources etc. (JL)
12/17/96 (new feature) Add an http Tcl script package to the Tcl library.
This package implements the client side of HTTP/1.0; the GET, HEAD,
and POST requests. (BW)
1/21/97 (new feature) Added a "marktrusted" subcommand to the "interp" and
to the interpreter object command. It removes the "safe" mark on an
interpreter and disables hard-wired checks for safety in the C sources. (JL)
1/21/97 (removed feature) Removed "vwait" from set of commands available in
a safe interpreter. (JL)
2/11/97 (new feature, bug fix) http package. Added -accept to http_config
so you can set the Accept header. Added -handler option to http_get so
you can supply your own data handler. Also fixed POST operation to
set the correct MIME type on the request. (BW)
----------------------------------------------------------
Changes for Tcl 7.7 go above this line.
Changes for Tcl 8.0 go below this line.
----------------------------------------------------------
9/17/96 (bug fix) Using "upvar" it was possible to turn an array element
into an array itself. Changed to disallow this; it was quirky and didn't
really work correctly anyway. (JO)
10/21/96 (new feature) The core of the Tcl interpreter has been replaced
with an on-the-fly compiler that translates Tcl scripts to bytecoded
instructions; a new interpreter then executes the bytecodes. The compiler
introduces only a few minor changes at the level of Tcl scripts. The biggest
changes are to expressions and lists.
- A second level of substitutions is no longer done for expressions.
This substantially improves their execution time. This means that
the expression "$x*4" produces a different result than in the past
if x is "$y+2". Fortunately, not much code depends on the old
two-level semantics. Some expressions that do, such as
"expr [join $list +]" can be recoded to work in Tcl8.0 by adding
an eval: e.g., "eval expr [join $list +]".
- Lists are now completely parsed on the first list operation to
create a faster internal representation. In the past, if you had a
misformed list but the erroneous part was after the point you
inserted or extracted an element, then you never saw an error.
In Tcl8.0 an error will be reported. This should only effect
incorrect programs that took advantage of behavior of the old
implementation that was not documented in the man pages.
Other changes to Tcl scripts are discussed in the web page at
http://www.scriptics.com/doc/compiler.html. (BL)
*** POTENTIAL INCOMPATIBILITY ***
10/21/96 (new feature) In earlier versions of Tcl, strings were used as a
universal representation; in Tcl 8.0 strings are replaced with Tcl_Obj
structures ("objects") that can hold both a string value and an internal
form such as a binary integer or compiled bytecodes. The new objects make it
possible to store information in efficient internal forms and avoid the
constant translations to and from strings that occurred with the old
interpreter. There are new many new C APIs for managing objects. Some of the
new library procedures for objects (such as Tcl_EvalObj) resemble existing
string-based procedures (such as Tcl_Eval) but take advantage of the
internal form stored in Tcl objects for greater speed. Other new procedures
manage objects and allow extension writers to define new kinds of objects.
See the manual entries doc/*Obj*.3 (BL)
10/24/96 (bug fix) Fixed memory leak on exit caused by some IO related
data structures not being deallocated on exit because their refcount was
artificially boosted. (JL)
10/24/96 (bug fix) Fixed core dump in Tcl_Close if called with NULL
Tcl_Channel. (JL)
11/19/96 (new feature) Added library procedures for finding word
breaks in strings in a platform specific manner. See the library.n
manual entry for more information. (SS)
11/22/96 (feature improvements) Added support for different levels of
tracing during bytecode compilation and execution. This should help in
tracking down suspected problems with the compiler or with converting
existing code to use Tcl8.0. Two global Tcl variables, traceCompile
and traceExec, can be set to generate tracing information in stdout:
- traceCompile: 0 no tracing (default)
1 trace compilations of top level commands and procs
2 trace and display instructions for all compilations
- traceExec: 0 no tracing
1 trace only calls to Tcl procs
2 trace invocations of all commands including procs
3 detailed trace showing the result of each instruction
traceExec >= 2 provides a one line summary of each called command and
its arguments. Commands that have been "compiled away" such as set are
not shown. (BL)
11/30/96 (bug fix) The command "info nameofexecutable" could sometimes
return the name of a directory. (JO)
11/30/96 (feature improvements) Changed the code in library/init.tcl
that reads in pkgIndex.tcl so that (a) it reads the files from child
directories before those in the parent, so that the parent gets
precedence, and (b) it doesn't quit if there is an error in a
pkgIndex.tcl file; instead, it prints an error message on standard
error and continues. (JO)
10/5/96 (feature improvements) Partial implementation of binary string
support: the ability for Tcl string values to contain embedded null bytes.
Changed the Tcl object-based APIs to take a byte pointer and length pair
instead of a null-terminated C string. Modified several object type managers
to support binary strings but not, for example, the list type manager.
Existing string-based C APIs are unchanged and will truncate binary
strings. Compiled scripts containing nulls are also truncated. (BL)
12/12/96 (feature change) Removed the commands "cp", "mkdir", "mv",
"rm", and "rmdir" from the Macintosh version of Tcl. They were never
officially supported and their functionality is now available via
the file command. (RJ)
----------------- Released 8.0a1, 12/20/96 -----------------------
1/7/97 (bug fix) Under Windows, "file stat c:" was returning error instead
of stat for current dir on c: drive.
1/10/97 (new feature) Added Tcl_GetIndexFromObj procedure for quick
lookups of keyword arguments. (JO)
1/12/97 (new feature) Serial IO channel drivers for Windows and Unix,
available by using Tcl open command to open pseudo-files like "com1:" or
"/dev/ttya". New option to Tcl fconfigure command for serial files:
"-mode baud,parity,data,stop" to specify baud rate, parity, data bits, and
stop bits. Serial IO is not yet available on Mac.
1/16/97 (feature change) Restored the Tcl7.x "two level substitution
semantics" for expressions. Expressions not enclosed in braces are
implemented, in general, by calling the expr command procedure
(Tcl_ExprObjCmd) at runtime after the Tcl interpreter has already done a
first round of substitutions. This is slow (about Tcl7.x speed) because new
code for the expression is generally compiled each time. However, if the
expression has only variable substitutions (and not command substitutions),
"optimistic" fast code is generated inline. This inline code will fail if a
second round of substitutions is needed (i.e., if the value of a substituted
variable itself requires more substitutions). The optimistic code will
catch the error and back off to call the slower but guaranteed correct
expr command procedure. (BL)
1/16/97 (feature improvements) Added Tcl_ExprLongObj and Tcl_ExprDoubleObj
to round out expression-related procedures. (BL)
1/16/97 (feature change) Under Windows, at startup the environment variables
"path", "comspec", and "windir" in any capitalization are converted
automatically to upper case. The PATH variable could be spelled as path,
Path, PaTh, etc. and it makes programming rather annoying. All other
environment variables are left alone. (CS)
1/20/97 (new features) Rewrote the "lsort" command:
- The new version is based on reentrant merge sort code provided
by Richard Hipp, so it eliminates the reentrancy and stability
problems with the old qsort-based implementation.
- The new version supports a -dictionary option for sorting, and
it also supports a -index option for sorting lists using one
element for comparison.
- The new version is an object command, so it works well with the
Tcl compiler, especially in conjunction with the new -index
option. When the -index option is used, this version of lsort
is more than 100 times faster than the Tcl 7.6 lsort, which had
to use the -command option to get the same effect. (JO)
1/20/97 (feature improvements) Added the improved debugging support for Tcl
objects prototyped by Karl Lehenbauer <karl@hammer1.ops.NeoSoft.com>.
If TCL_MEM_DEBUG is defined, the object creation calls use Tcl_DbCkalloc
directly in order to record the caller's source file name and line
number. (BL)
1/21/97 (removed feature) Desupported the tcl_precision variable: if
set, it is ignored. Tcl now uses the full 17 digits of precision when
converting real numbers to strings (with the new object system real
numbers are rarely converted to strings so there is no efficiency
disadvantage to printing all 17 digits; the new scheme improves
accuracy and simplifies several APIs). (JO)
*** POTENTIAL INCOMPATIBILITY ***
1/21/97 (feature change) Removed the "interp" argument for the
procedures Tcl_GetStringFromObj, Tcl_StringObjAppend, and
Tcl_StringObjAppendObj. Also removed the "interp" argument for
the updateStringProc procedure in Tcl_ObjType structures. With
the tcl_precision changes above, these are no longer needed. (JO)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a1, but not with Tcl 7.6 ***
1/22/97 (bug fix) Fixed http.tcl so that http_reset does not result in
an extra call to the command callback. In addition, if the transaction
gets a premature eof, the state(status) is "eof", not "ok". (BW)
----------------- Released 8.0a2, 1/24/97 -----------------------
1/29/97 (feature change) Changed how two digit years are parsed in the
clock command. The old interface just added 1900 which will seem
broken by the year 2000. The new scheme follows the POSIX standard
and treats dates 70-99 as 1970-1999 and dates 00-38 as 2000-2038. All
other two digit dates are undefined. (RJ)
*** POTENTIAL INCOMPATIBILITY ***
2/4/97 (bug fix) Fixed bug in clock code that dealt with relative
dates. Using the relative month code you could get an invalid date
because it jumped into a non-existant day. (For example, Jan 31
to Feb 31.) The code now will return the last valid day of the
month in these situations. Thanks to Hume Smith for sending in
this bug fix. (RJ)
2/10/97 (feature change) Eliminated Tcl_StringObjAppend and
Tcl_StringObjAppendObj procedures, replaced them with Tcl_AppendToObj
and Tcl_AppendStringsToObj procedures. Added new procedure
Tcl_SetObjLength. (JO)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2, but not with Tcl 7.6 ***
2/10/97 (new feature) Added Tcl_WrongNumArgs procedure for generating
error messages about incorrect number of arguments. (JO)
2/11/97 (new feature, bug fix) http package. Added -accept to http_config
so you can set the Accept header. Added -handler option to http_get so
you can supply your own data handler. Also fixed POST operation to
set the correct MIME type on the request. (BW)
2/22/97 (bug fix) Fixed bug that caused $tcl_platform(osVersion) to be
computed incorrectly under AIX. (JO)
2/25/97 (new feature, feature change) Added support for both int and long
integer objects. Added Tcl_NewLongObj/Tcl_GetLongFromObj/Tcl_SetLongFromObj
procedures and renamed the Tcl_Obj internalRep intValue member to
longValue. Tcl_GetIntFromObj now checks for integer values too large to
represent as non-long integers. Changed Tcl_GetAllObjTypes to
Tcl_AppendAllObjTypes. (BL)
3/5/97 (new feature) Added new Tcl_SetListObj procedure to round out
collection of procedures that set the type and value of existing Tcl
objects. (BL)
3/6/97 (new feature) Added -global flag for interp invokehidden. (JL)
3/6/97 (new feature, feature change) Added isNativeObjectProc field to the
Tcl_CmdInfo structure to indicate (when 1) if the command has an
object-based command procedure. Removed the nameLength arg from
Tcl_CreateObjCommand since command names can't contain null characters. (BL)
3/6/97 (bug fix) Fixed bug in "unknown" procedure that caused auto-
loading to fail on commands whose names begin with digits. (JO)
3/7/97 (bug fix) Auto-loading now works in Safe Base. Safe interpreters
only accept the Version 2 and onwards tclIndex files. (JL)
3/13/97 (bug fix) Fixed core dump due to interaction between aliases and
hidden commands. Bug found by Lindsay Marshall. (JL)
3/14/97 (bug fix) Fixed mac bugs relating to time. The -gmt option
now adjusts the time in the correct direction. (Thanks to Ed Hume for
reporting a fix to this problem.) Also fixed file "mtime" etc. to
return times from GMT rather than local time zone. (RJ)
3/18/97 (feature change) Declaration of objv in Tcl_ObjCmdProc function
changed from "Tcl_Obj *objv[]" to "Tcl_Obj *CONST objv[]". All Tcl object
commands changed to use new declaration of objv. Naive translation of
string-based command procs to object-based command procs could very easily
have yielded code where the contents of the objv array were changed. This
is not a problem with string-based command procs, but doing something as
simple as objv[2] = objv[3] would corrupt the runtime stack and cause Tcl to
crash. Introduced CONST in declaration of objv so that attempted assignment
of new pointer values to elements of the objv array will be caught by the
compiler. (CCS)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 ***
3/19/97 (bug fix) Fixed panic due to object sharing. The root cause was
that old code was using Tcl_ResetResult instead of Tcl_ResetObjResult. (JL)
3/20/97 (new feature) Added a new subcommand for the file
command. file attributes filename can give a list of platform-specific
options (such as file/creator type on the Mac, permissions on Unix) or
set the values of them. Added a new subcommand for the file
command. file nativename name gives back the platform-specific form
for the file. This is useful when the filename is needed to pass to
the OS, such as exec under Windows 95 or AppleScript on the Mac. For
more info, see file.n. (SRP)
3/24/97 (removed feature) Removed the tcl_safePolicyPath procedure. Now
the policy path is computed from the auto_path by appending the directory
'policies' to each element. Also fixed several bugs in automatic tracking
of auto_path by computed policy path. (JL)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 ***
4/8/97 (new feature) If the variable whose name is passed to lappend doesn't
already exist, and there are no value arguments, lappend now creates the
variable with an empty value instead of returning an error. Change suggested
by Tom Tromey. (BL)
4/9/97 (feature change) Changed the name of the TCL_PART1_NOT_PARSED flag to
TCL_PARSE_PART1. (BL)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 but not with Tcl 7.6 ***
4/10/97 (bug fixes) Fixed various compilation-related bugs:
- "UpdateStringOfCmdName should never be invoked" panic.
- Bad code generated for expressions not in {}'s inside catch commands.
- Segmentation fault in some command procedures when two argument
object pointers refer to the same object.
- Second level of substitutions were never done for expressions not
in {}'s that consist of a single variable reference: e.g.,
"set x 27; set bool {$x}; if $bool {puts foo}" would fail with error.
- Bad code generated when code storage was grown while compiling some
expressions: ones with compilation errors or consisting of only a
variable reference.
- Bugs involving multiple interpreters: wasn't checking that a
procedure's code was compiled for the same interpreter as the one
executing it, and didn't invalidate code on hidden-exposed command
transitions.
- "Bad stack top" panic when executing scripts that require a huge
amount of stack space.
- Incorrect sharing of code for procedure bodies, and procedure code
deallocated before last execution of the procedure finished.
- Fixed compilation of expression words in quotes. For example,
if "0 < 3" {puts foo}.
- Fixed performance bug in array set command with large assignments.
- Tcl_SetObjLength segmentation fault setting length of empty object.
- If Tcl_SetObjectResult was passed the same object as the interpreter's
result object, it freed the object instead of doing nothing. Bug fix
by Michael J. McLennan.
- Tcl_ListObjAppendList inserted elements from the wrong list. Bug fix
by Michael J. McLennan.
- Segmentation fault if empty variable list was specified in a foreach
command. Bug fix by Jan Nijtmans.
- NULL command name was always passed to Tcl_CreateTrace callback
procedure.
- Wrong string representation generated for the value LONG_MIN.
For example, expr 1<<31 printed incorrectly on a 32 bit machine.
- "set {a($x)} 1" stored value in wrong variable.
- Tcl_GetBooleanFromObj was not checking for garbage after a numeric
value.
- Garbled "bad operand type" error message when evaluating expressions
not surrounded by {}'s. (BL)
4/16/97 (new feature) The expr command now has the "rand()" and
"srand()" functions for getting random numbers in expr. (RJ)
4/23/97 (bug fix) Fixed core dump in bgerror when the error handler command
deletes the current interpreter. Found by Juergen Schoenwald. (JL)
4/23/97 (feature change) The notifier interfaces have been redesigned
to make embedding in applications with external event loops possible.
A number of interfaces in the notifier and the channel drivers have
changed. Refer to the Notifier.3 and CrtChannel.3 manual entries for
more details. (SS)
*** POTENTIAL INCOMPATIBILITY ***
4/23/97 (removed feature) The Tcl_File interfaces have been removed.
The Tcl_CreateFileHandler/Tcl_DeleteFileHandler interfaces now take
Unix fd's and are only supported on the Unix platform.
Tcl_GetChannelFile has been replaced with Tcl_GetChannelHandle.
Tcl_MakeFileChannel now takes a platform specific file handle. (SS)
*** POTENTIAL INCOMPATIBILITY ***
4/23/97 (removed feature) The modal timeout interface has been
removed (Tcl_CreateModalTimeout/Tcl_DeleteModalTimeout) (SS)
*** POTENTIAL INCOMPATIBILITY ***
4/23/97 (feature change) Channel drivers are now required to correctly
implement blocking behavior when they are in blocking mode. (SS)
*** POTENTIAL INCOMPATIBILITY ***
4/23/97 (new feature) Added the "binary" command for manipulating
binary strings. Also, changed the "puts", "gets", and "read" commands
to preserve embedded nulls. (SS)
4/23/97 (new feature) Added tcl_platform(byteOrder) element to the
tcl_platform array to identify the native byte order for the current
host. (SS)
4/23/97 (bug fix) Fixed bug in date parsing around year boundaries. (SS)
4/24/97 (bug fix) In the process of copying a file owned by another user,
Tcl was changing the owner of the copy back to the owner of the original
file, therefore causing further file operations to fail because the current
user didn't own the copy anymore. The owner of the copy is now left as the
current user. (CCS)
4/24/97 (feature change) Under Windows, don't automatically uppercase the
environment variable "windir" -- it's supposed to be lower case. (CCS)
4/29/97 (new feature) Added namespace support based on a namespace
implementation by Michael J. McLennan of Lucent Technologies. A namespace
encapsulates a collection of commands and variables to ensure that they
won't interfere the commands and variables of other namespaces. The global
namespace holds all global variables and commands. Additional namespaces are
created with the new namespace command. The new variable command lets you
create Tcl variables inside a namespace. The names of Tcl variables and
commands may now be qualified by the name of the namespace containing them.
The key namespace-related commands are summarized below:
- namespace ?eval? name arg ?arg...?
Used to define the commands and variables in a namespace.
Optionally creates the namespace.
- namespace export ?-clear? ?pattern pattern...?
Specifies which commands are exported from a namespace. These
are the ones that can be imported into another namespace.
- namespace import ?-force? ?pattern pattern...?
Makes the specified commands accessible in the current namespace.
- namespace current
Returns the name of the current namespace.
- variable name ?value? ?name ?value?...?
Creates one or more namespace variables. (BTL)
5/1/97 (bug fix) Under Windows, file times were reported in GMT. Should be
reported in local time. (CCS)
5/2/97 (feature change) Changed the name of the two Tcl variables used for
tracing bytecode compilation and execution to tcl_traceCompile and
tcl_traceExec respectively. These variables are now documented in the
tclvars man page. (BL)
5/5/97 (new feature) Support "end" as the index for "lsort -index". (BW)
5/5/97 (bug fixes) Cleaned up the way the http package resets connections (BW)
5/8/97 (feature change) Newly created Tcl objects now have a reference count
of zero instead of one. This simplifies C code that stores newly created
objects in Tcl variables or in data structures such as list objects. That C
code must increment the new object's reference count since the variable or
data structure will contain a long-term reference to the object. Formerly,
when new objects started out with reference count one, it was necessary to
decrement the new object's reference count after the store to make sure it
was left with the correct value; this is no longer necessary. (BL)
5/9/97 (new feature) Added the Tcl_GetsObj interface that takes an
object reference instead of a dynamic string (as in Tcl_Gets). (SS)
5/12/97 (new feature) Added Tcl_CreateAliasObj and Tcl_GetAliasObj C APIs
to allow an alias command to be created with a vector of Tcl_Obj structures
and to get the vector back later. (JL)
5/12/97 (feature change) Changed Tcl_ExposeCommand and Tcl_HideCommand to
leave an object result instead of a string result. (JL)
5/14/97 (feature change) Improved the handling of the interpreter result.
This is still either an object or a string, but the two values are now kept
consistent unless some C code reads or writes interp->result directly. See
the SetResult man page for details. Removed the Tcl_ResetObjResult
procedure. (BL)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0a2 ***
5/16/97 (new feature) Added "fcopy" command to move data between
channels. Refer to the manual page for more information. Removed the
"unsupported0" command since it is obsolete now. (SS)
5/16/97 (new feature) Added Tcl_GetStringResult procedure to allow programs
to get an interpreter's result as a string. If the result was previously set
to an object, this procedure will convert the object to a string. Use of
Tcl_GetStringResult is intended to replace direct access to interp->result,
which is not safe. (BL)
5/20/97 (new features) Fixed "fcopy" to return the number of bytes
transferred in the blocking case. Updated the http package to use
fcopy instead of unsupported0. Added -timeout and -handler options to
http_get. http_get is now blocking by default. It is only non-blocking
if you supply a -command argument. (BW)
5/22/97 (bug fix) Fixed several bugs in the "lsort" command having to do
with the -dictionary option and the presence of numbers embedded in the
strings. (JO)
----------------- Released 8.0b1, 5/27/97 -----------------------
6/2/97 (bug fix) Fixed bug in startup code that caused a problem in
finding the library files when they are installed in a directory
containing a space in the name. (SS)
6/2/97 (bug fix) Fixed bug in Unix notifier where the select mask was
not being cleared under some circumstances. (SS)
6/4/97 (bug fix) Fixed bug that prevented creation of Tk widgets in
namespaces. Tcl_CreateObjCommand and Tcl_CreateCommand now always create
commands in the global namespace unless the command names are qualified. Tcl
procedures continue to be created in the current namespace by default. (BL)
6/6/97 (new features) Added new namespace API procedures
Tcl_AppendExportList and Tcl_Export to allow C code to get and set a
namespace's export list. (BL)
6/11/97 (new feature) Added Tcl_ConcatObj. This object-based routine
parallels the string-based routine Tcl_Concat. (SRP)
6/11/97 (new feature) Added Tcl_SetObjErrorCode. This object-based
routines parallels the string-based routine Tcl_SetErrorCode. (SRP)
6/12/97 (bug fix) Fix the "unknown" procedure so that wish under Windows
will exec an external program, instead of always complaining "console1 not
opened for writing". (CCS)
6/12/97 (bug fix) Fixed core dump experienced by the following simple
script:
interp create x
x alias exec exec
interp delete x
This panic was caused by not installing the new CmdDeleteProc when exec
got redefined by the alias creation step. Reported by Lindsay Marshal (JL)
6/13/97 (new features) Tcl objects newly created by Tcl_NewObj now have a
string representation that points to a shared heap string of length 1. (They
used to have NULL bytes and typePtr fields. This was treated as a special
case to indicate an empty string, but made type manager implementations
complex and error prone.) The new procedure Tcl_InvalidateStringRep is used
to mark an object's string representation invalid and to free any storage
associated with the old string representation. (BL)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 ***
6/16/97 (bug fix) Tcl_ScanCountedElement could leave braces unmatched
if the string ended with a backslash. (JO)
6/17/97 (bug fix) Fixed channel event bug where readable events would be
lost during recursive events loops if the input buffers contained
data. (SS)
6/17/97 (bug fix) Fixed bug in Windows socket code that didn't
reenable read events in the case where an external entity is also
reading from the socket. (SS)
6/18/97 (bug fix) Changed initial setting of the notifier service mode
to TCL_SERVICE_NONE to avoid unexpected event handling during
initialization. (SS)
6/19/97 (bug fix/feature change) The command callback to fcopy is now
called in case of errors during the background copy. This adds a second,
optional argument to the callback that is the error string. The callback
in case of errors is required for proper cleanup by the user of fcopy. (BW)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
6/19/97 (bug fix) Fixed a panic due to the following four line script:
interp create x
x alias foo bar
x eval rename foo blotz
x alias foo {}
The problem was that the interp code was not using the actual current name
of the command to be deleted as a result of un-aliasing foo. (JL)
6/19/97 (feature change) Pass interp down to the ChannelOption and
driver specific calls so system errors can be differentiated from syntax
ones. Changed Tcl_DriverGetOptionProc type. Affects Tcl_GetChannelOption,
TcpGetOptionProc, TtyGetOptionProc, etc. (DL)
*** POTENTIAL INCOMPATIBILITY ***
6/19/97 (new feature) Added Tcl_BadChannelOption for use by by driver
specific option procedures (Set and Get) to return a complete and
meaningful error message. (DL)
6/19/97 (bug fixes) If a system call error occurs while doing an
fconfigure on tcp or tty/com channel: return the appropriate error
message (instead of the syntax error one or none). (Fixed for Unix and
most of the Win and Mac drivers). (DL)
6/20/97 (feature change) Eval is no longer assumed as the subcommand name
in namespace commands: you must now write "namespace eval nsName {...}".
Abbreviations of namespace subcommand names are now allowed. (BL)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl7.6 ***
6/20/97 (feature change) Changed the errorInfo traceback message for
compilation errors from "invoked from within" to "while compiling". (BL)
6/20/97 (bug fixes) Fixed various compilation-related bugs:
- "UpdateStringOfCmdName should never be called" and
"UpdateStringOfByteCode should never be called" panics.
- Segfault in TclObjInterpProc getting procedure name after evaluation
stack is reallocated (grown).
- Could not use ":" at end of variable and command names.
- Bad code generated for while and for commands with test expressions
enclosed in quotes: e.g., "set i 0; while "$i > 5" {}".
- Command trace procedures would crash if they did a Tcl_EvalObj that
reallocated the evaluation stack.
- Break and continue commands did not reset the interpreter result.
- The Tcl_ExprXXX routines, both string- or object-based, always
modified the interpreter result even if there was no error.
- The argument parsing procedure used by several compile procedures
always treated "]" as end of a command: e.g., "set a ]" would fail.
- Changed errorInfo traceback message for compilation errors from
"invoked from within" to "while compiling".
- Problem initializing Tcl object managers during interpreter creation.
- Added check and error message if formal parameter to a procedure is
an array element. (BL)
6/23/97 (new feature) Added "registry" package to allow manipulation
of the Windows system registry. See manual entry for details. (SS)
6/24/97 (feature change) Converted http to a package and added the
http1.0 subdirectory of the Tcl script library. This means you have
to do a "package require http" to use this, as advertised in the man page. (BW)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
6/24/97 (bug fix) Ensure that Tcl_Set/GetVar C APIs, when called without
TCL_LEAVE_ERR_MSG, don't touch the interp result. (DL)
6/26/97 (feature change) Changed name of Tcl_ExprStringObj to
Tcl_ExprObj. (BL)
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b1, but not with Tcl 7.6 ***
----------------- Released 8.0b2, 6/30/97 -----------------------
7/1/97 (new feature) TCL_BUILD_SHARED flag set in tclConfig.sh
when Tcl has been built with --enable-shared. A new tclLibObjs
make target, echoing the list of the .o's needed to build a tcl
library, is now provided. (DL)
7/1/97 (feature change) compat/getcwd.c removed and changed the
only place where getcwd is used so a new USEGETWD flag selects
the use of the replacement "getwd". Adding this flag is recommended
for SunOS 4 (because getcwd on SunOS 4 uses a pipe to pwd(1)!). (DL)
7/7/97 (feature change) The split command now supports binary data (i.e.,
null characters in strings). (BL)
7/7/97 (bug fix) string first returned the wrong result if the first
argument string was empty. (BL)
7/8/97 (bug fix) Fixed core dump in fcopy that could occur when a command
callback was supplied and an error or eof condition caused no background
activity. A refcount bug triggered a panic in Tcl_ListObjAppendElement. (BW)
7/8/97 (bug fix) Relaxed the pattern matching on http_get so you do not
need a trailing path component. You can now get away with just
http_get www.scriptics.com (BW)
7/9/97 (bug fix) Creating anonymous interpreters no longer smashes existing
commands with names similar to the generated name. Previously creating an
anonymous interpreter could smash an existing command, now it skips until
it finds a command name that isn't being used. (JL)
7/9/97 (feature change) Removed the policy management mechanism from the
Safe Base; left the aliases to source and load modules, and to do a limited
form of the "file" command. See entry of 11/15/96. (JL)
7/9/97 (bug fixes) Fixed various compilation-related bugs:
- Line numbers in errorInfo now are the same as those in Tcl7.6 unless
there are compilation errors. Compilation error messages now include the
entire command in error.
- Trailing ::s after namespace names weren't being ignored.
- Could not refer to an namespace variable with an empty name using a
name of the form "n::". (BL)
7/9/97 (bug fix) Fixed bug in Tcl_Export that prevented you from exporting
from other than the current namespace. (BL)
7/9/97 (bug fix) env.test was removing env var needed for proper finding
of libraries in child process. (DL)
7/10/97 (bug fixes/new feature) Cleanup in Tcl_MakeSafe. Less information
is leaked to safe interps. Error message fixes for interp sub commands.
Likewise changes in safealias.tcl; tcl_safeCreateInterp can now be called
without argument to generate the slave name (like in interp create). (DL)
7/10/97 (bug fixes) Bytecode compiler now generates more detailed
command location information: subcommands as well as commands now have
location information. This means command trace procedures now get the
correct source string for each command in their command parameter. (BL)
7/22/97 (bug fixes) Performance improvement in Safe interpreters
handling. Added new mask value to (tclInt.h) Interp.flags record. (DL)
7/22/97 (bug fix) Fixed panic in 'interp target {} foo'. This bug
was present since Tcl 7.6. (JL)
7/22/97 (bug fix) Fixed bug in compilation of procedures in namespaces: the
procedure's namespace must be used to look up compile procedures, not the
current namespace. (BL)
7/22/97 (bug fix) Use of the -channel option of http_get was not setting
the end of line translations mode on the channel, so copying binary data
with the -channel option was corrupting the result on non-unix platforms. (BW)
7/22/97 (bug fixes) file commands and ~user (seg fault and other
improper returns). (DL)
7/23/97 (feature change) Reenabled "vwait" in Safe Base. (JL)
7/23/97 (bug fixes) Fixed two bugs involving read traces on array variables
in procedures: trace procedures were sometimes not called, and reading
nonexistant array elements didn't create undefined element variables that
could later be defined by trace procedures. (BL)
7/24/97 (bug fix) Windows memory allocation performance was
superlinear in some cases. Made the Mac allocator generic and changed
both the Mac and Windows platforms to use the new allocator instead of
malloc and free. (SS)
7/24/97 - 8/12/97 (bug fixes/change of features) Completely revamped safe
sourcing/loading (see safe.n) to hide pathnames, use virtual
paths tokens instead, improved security in several respects and made it
more tunable. Multi level interp loading can work too now. Package auto
loading now works in safe interps as long as the package directory is in
the auto_path (no deep crawling allowed in safe interps). (DL)
*** POTENTIAL INCOMPATIBILITY with previous alpha and beta releases ***
7/24/97 (bug fixes) Made Tcl_SetVar* and Tcl_NewString* treat a NULL value
as an empty string. (This fixes hairy crash case where you would crash
because load command for other interps assumed presence of
errorInfo...). (DL)
7/28/97 (bug fix) Fixed pkg_mkIndex to understand namespaces. It will
use the export list of a namespace and create auto_index entries for
all export commands. Those names are in their fully qualified form in the
auto_index. Therefore, I tweaked unknown to try both $cmd and ::$cmd.
Also fixed pkg_mkIndex so you can have "package require" commands inside
your packages. These commands are ignored, which is mostly ok except
when you must load another package before loading yours because of
linking dependencies. (BW)
7/28/97 (bug fix) A variable created by the variable command now persists
until the namespace is destroyed or the variable is unset. This is true even
if the variable has not been initialized; these variables used to be
destroyed if an error occurred when accessing them. In addition, the "info
vars" command lists uninitialized namespace variables, while the "info
exists" command returns 0 for them. (BL)
7/29/97 (feature change) Changed the http package to use the ::http
namespace. http_get renamed to http::geturl, http_config renamed to
http::config, http_formatQuery renamed to http::formatQuery.
It now provides the 2.0 version of the package.
The 1.0 version is still available with the old names.
*** POTENTIAL INCOMPATIBILITY with Tcl 8.0b2 but not with Tcl 7.6 ***
7/29/97 (bug fix, new feature) Tcl_Main now uses Tcl objects internally to
preserve NULLs in commands and command output. Added new API procedure
Tcl_RecordAndEvalObj that resembles Tcl_RecordAndEval but takes an object
containing a command. (BL)
7/30/97 (bug fix) Tcl freed strings in the environ array even if it
did not allocate them. (SS)
7/30/97 (bug fix) If a procedure is renamed into a different namespace, it
now executes in the context of that namespace. (BL)
7/30/97 (bug fix) Prevent renaming of commands into and from namespaces as
part of hiding them. (JL)
7/31/97 (feature change) Moved the history command from C to tcl.
This uses the ::history namespace. The "words" and "substitute" options
are no longer supported. In addition, the "keep" option without a value
returns the current keep limit. There is a new "clear" option.
The unknown command now supports !! again. (BW)
*** POTENTIAL INCOMPATIBILTY ***
7/30/97 (bug fix) Made sure that a slave can not fool the master into
hiding the wrong command. Made sure we don't crash in hiding + namespaces
issues. (DL)
8/4/97 (bug fix) Concat, eval, uplevel, and similar commands were
incorrectly trimming trailing space characters from their arguments
even when the space characters were preceded by a backslash. (JO)
8/4/97 (bug fix) Removed the hard link between bgerror and tkerror.
Only bgerror is supported in tcl core. Tk will still look for a
tkerror but using regular tcl code for that feature. (DL)
*** POTENTIAL INCOMPATIBILTY with code relying on the hard link ***
8/6/97 (bug fix) Reduced size required for compiled bytecodes by using a
more compact encoding for the command pc-to-source map. (BL)
8/6/97 (new feature) Added support for additional compilation and execution
statistics when Tcl is compiled with the TCL_COMPILE_STATS flag. (BL)
8/7/97 (bug fix) Expressions not in {}s that have a comparison operator as
the topmost operator must be compiled out-of-line (call the expr cmd at
runtime) to properly support expr's two-level substitution semantics. An
example is "set a 2; set b {$a}; puts [expr $b == 2]". (BL)
8/11/97 (bug fix) The catch command would sometimes crash if a variable name
was given and the bytecode evaluation stack was grown when executing the
argument script. (BL)
8/12/97 (feature change) Reinstated the variable tcl_precision to control
the number of digits used when floating-point values are converted to
strings, with default of 12 digits. However, had to make tcl_precision
shared among all interpreters (except that safe interpreters can't
modify it). This makes the Tcl 8.0 behavior almost identical to 7.6
except that the default precision is 12 instead of 6. (JO)
*** POTENTIAL INCOMPATIBILITY ***
----------------- Released 8.0, 8/18/97 -----------------------
8/19/97 (bug fix) Minimal fix for glob -nocomplain bugs:
"glob -nocomplain unreadableDir/*" was generating an anonymous
error. More in depth fixes will come with 8.1. (DL).
8/20/97 (bug fix) Removed check for FLT_MIN in binary command so
underflow conditions are handled by the compiler automatic
conversions. (SS)
8/20/97 (bug fixes) Fixed several compilation-related bugs:
- Array cmd wasn't detecting arrays that, while compiled, do not yet
exist (e.g., are marked undefined since they haven't been assigned
to yet).
- The GetToken procedure in tclCompExpr.c wasn't recognizing properly
whether an integer token was invalid. For example, "0x$" is not
a valid integer.
- Performance bug in TclExecuteByteCode: the size of its stack frame
was reduced by over 20% by moving errorInfo code elsewhere.
- Uninitialized memory read error in tclCompile.c. (BL)
8/21/97 (bug fix) safe::interpConfigure now behave like Tk widget's
configure : it changes only the options you provide and you can get
the current value of any single option. New ?-nested boolean? and
?-statics boolean? for all safe::interp* commands but we still
accept (upward compatibility) the previously defined non valued
flags ?-noStatics? and ?-nestedLoadOk?. Improved the documentation. (DL).
8/22/97 (bug fix) Updated PrintDbl.3 to reflect the fact that the
tcl_precision variable is still used and that it is now shared by all
interpreters. (BL)
8/25/97 (bug fix) Fixed array access bug in IllegalExprOperandType
procedure in tclExecute.c: it was not properly supporting the || and &&
operators. (BL)
8/27/97 (bug fix) In cases where a channel handler was created with an
empty event mask while data was still buffered in the channel, the
channel code would get stuck spinning on a timer that would starve
idle handlers. This mostly happened in Tk when reading from stdin. (SS)
9/4/97 (bug fix) Slave interps now inherit the maximum recursion limit
of their parent instead of starting back at the default. {nb: this still
does not prevent stack overflow by multi-interps recursion or aliasing} (DL)
9/11/97 (bug fix) An uninitialized variable in Tcl_WaitPid caused
pipes to fail to report eof properly under Windows. (SS)
9/12/97 (bug fix) "exec" was misidentifying some DOS executables as not
executable. (CCS)
9/14/97 (bug fix) Was using the wrong structure in sizeof operation in
tclUnixChan.c. (JL)
9/15/97 (bug fix) Fixed notifier to break out of do-one-event loop if
Tcl_WaitForEvent returns 1, so that callers of Tcl_DoOneEvent will get
a chance to check whether the event just handled is significant. This
affected mainly recursive calls to Tcl_VWaitCmd; these did not get a
chance to notice that the variable they were waiting for has been set
and thus they didn't terminate the vwait. (JL, DL, SS)
9/15/97 (bug fix) Alignment problems in "binary format" would cause a
crash on some platforms when formatting floating point numbers. (SS)
9/15/97 (bug fix) Fixed bug in Macintosh socket code. Now passes all
tests in socket.test that are not platform specific. (Thanks to Mark
Roseman for the pointer on the fix.) (RJ)
9/18/97 (bug fix) Fixed bug -dictionary option of lsort that could
cause the compare function to run off the end of an array if the
number only contained 0's. (Thanks to Greg Couch for the report.) (RJ)
9/18/97 (bug fix) TclFinalizeEnvironment was not cleaning up
properly. (DL, JI)
9/18/97 (bug fix) Fixed long-standing bug where an "array get" command
did not trigger traces on the array or its elements. (BL)
9/18/97 (bug fixes) Fixed compilation-related bugs:
- Fixed errorInfo traceback information for toplevel coomands that
contain nested commands.
- In the expr command, && and || now accept boolean operands as well
as numeric ones. (BL)
9/22/97 (bug fix) Fixed bug that prevented translation modes from being
set independently for input and output on sockets if input was "auto". (JL)
9/24/97 (bug fix) Tcl_EvalFile(3) and thus source(n) now works fine on
files containing NUL chars. (DL)
9/26/97 (bug fix) Fixed use of uninitialized memory in the environ array
that later could cause random core dumps. Applies to all platforms. (JL)
9/26/97 (bug fix) Fixed use of uninitialized memory in socket address data
structure under some circumstances. This could cause random core dumps.
This applies only to Unix. (JL)
9/26/97 (bug fix) Opening files on PC-NFS volumes would cause a hang
until the system timed after the file was closed. (SS)
10/6/97 (bug fix) The join(n) command, though objectified, was loosing
NULs in the joinString and in list elements after the 2nd one.
Now you can "join $list \0" for instance. (DL)
10/9/97 (bug fix) Under windows, if env(TMP) or env(TEMP) referred to a
non-existent directory, exec would fail when trying to create its temporary
files. (CCS)
10/9/97 (bug fix) Under mac and windows, "info hostname" would crash if
sockets were installed but the hostname could not be determined anyhow.
Tcl_GetHostName() was returning NULL when it should have been returning
an empty string. (CCS)
10/10/97 (bug fix) "file attribute /" returned error on windows. (CCS)
10/10/97 (bug fix) Fixed the auto_load procedure to handle procedures
defined in namespaces better. Also fixed pgk_mkIndex so it sees procedures
defined in nested namespaces. Index entries are still only made for
exported procedures. (BW)
10/13/97 (bug fix) On unix, for files with unknown group or owner
attributes, querying the "file attributes" would return an error rather than
returning the group's or owner's id number, although tha command accepts
numbers when setting the file's group or owner. (CCS)
10/22/97 (bug fix) "fcopy" did not eval the callback script at the
global scope. (SS)
10/22/97 (bug fix) Fixed the signature of the CopyDone callback used in
the http package(s) so they can handle error cases properly. (BW)
10/28/97 (bug fixes) Fixed a problem where lappend would free the Tcl object
in a variable if a Tcl_ObjSetVar2 failed because of an error calling a trace
on the variable. (BL)
10/28/97 (bug fix) Changed binary scan to properly handle sign
extension of integers on 64-bit or larger machines. (SS)
11/3/97 (bug fixes) Fixed several bugs:
- expressions such as "expr ($x)" must be compiled out-of-line
(call the expr command procedure at runtime) to ensure the correct
behavior when "$x" is an expression such as "5+10".
- "array set a {}" now creates a new array var with an empty array
value if the var didn't already exist.
- "lreplace $foo end end" no longer returns an error (just an empty
list) if foo is empty.
- upvar will no longer create a variable in a namespace that refers
to a variable in a procedure.
- deleting a command trace within a command trace callback would
make the code that calls traces to reference freed memory.
- significantly sped up "string first" and "string last" (fix from
darrel@gemstone.com).
- seg fault in Tcl_NewStringObj() when a NULL is passed as the byte
pointer argument and Tcl is compiled with -DTCL_MEM_DEBUG.
- documentation and error msg fixes. (BL)
11/3/97 (bug fix) Fixed a number of I/O bugs related to word sizes on
64-bit machines. (SS)
11/6/97 (bug fix) The exit code of the first process created by Tcl
on Windows was not properly reported due to an initialization
problem. (SS)
----------------- Released 8.0p1, 11/7/97 -----------------------
11/19/97 (bug fix) Fixed bug in linsert where it sometimes accidently
cleared out a shared argument list object. (BL).
11/19/97 (bug fix) Autoloading in namespaces was not working properly.
auto_mkindex is still not really namespace aware but most common
cases should now be handled properly (see init.test). (BW, DL)
11/20/97 (enhancement) Made the changes required by the new Apple
Universal Headers V.3.0, so that Tcl will compile with CW Pro 2.
11/24/97 (bug fix) Fixed tests in clock test suite that needed the
-gmt flag set. Thanks to Jan Nijtmans for reporting the problem. (RJ)
----------------- Released 8.0p2, 11/25/97 -----------------------
12/3/97 (bug fix/optimization) Removed uneeded and potentially dangerous
instances of double evaluations if "if" and "expr" statements from
the library files. It is recommended that unless you need a double
evaluation you always use "expr {...}" instead of "expr ..." and
"if {...} ..." instead of "if ... ...". It will also be faster
thanks to the byte compiler. (DL)
---- Shipped as part of the plugin2.0b5 as 8.0p2Plugin1, Dec 8th 97 ----
12/8/97 (bug fix) Need to protect the newly accepted channel in an
accept callback on a socket, otherwise the callback may close it and
cause an error, which would cause the C code to attempt to close the
now deleted channel. Bumping the refcount assures that the channel sticks
around to be really closed in this case. (JL)
12/8/97 (bug fix) Need to protect the channel in a fileevent so that it
is not deleted before the fileevent handler returns. (CS, JL)
12/18/97 (bug fix) In the opt argument parsing package: if the description
had only flags, the "too many arguments" case was not detected. The default
value was not used for the special "args" ending argument. (DL)
1/15/98 (improvement) Moved common part of initScript in common file.
Moved windows specific initialization to init.tcl so you can initialize
Tcl in windows without having to call Tcl_Init which is now only
searching for init.tcl {back ported from 8.1}. (DL)
---- Shipped as part of the plugin as 8.0p2Plugin2, Jan 15th 98 ----
5/27/98 (bug fix) Windows socket driver did not notice new data arriving
on nonblocking sockets until the event loop was entered. (SS)
5/27/98 (bug fix) Windows socket driver used FIONREAD, which is not
supported correctly by WinSock. (SS)
6/9/98 (bug fix) Generic channel code failed to report readable file
events on buffered data that was left behind by a gets or read that
did not consume all available data. (SS)
6/18/98 (bug fix) Compilation of loop expressions was too aggressive
and incorrectly inlined non-literal expressions. (SS)
6/18/98 (bug fix) "info var" and "info locals" incorrectly reported
the existence of compiler temporary variables. (SS)
6/18/98 (bug fix) Dictionary sorting used signed character
comparisons. (SS)
6/18/98 (bug fix) Compile procs corrupted the exception stack in some
cases. (SS)
6/18/98 (bug fix) Array set had erratic behavior when initializing a
variable from an empty value list. (SS)
6/18/98 (bug fix) The Windows registry package had a bad bounds check
that could lead to a crash. (SS)
6/18/98 (bug fix) The foreach compile proc did not correctly handle
non-local variable references. (SS)
6/25/98 (new features) Added name resolution hooks to support [incr Tcl].
There are new internal Tcl_*Resolver* APIs to add, query and remove the hooks.
With this changes it should be possible to dynamically load [incr Tcl]
as an extension. (MM)
7/1/97 (bug fix) The commands "info args, body, default, procs" did
not correctly handle imported procedures. (RJ)
7/6/98 (improvement) pkg_mkIndex now implements the "package require"
command. This makes it possible to create index files for packages
that require another package and then execute code from that package in
their file. Previously, this would throw an error because the required
package had not been loaded. The -nopkgrequied flag is provided to
revert back to the old functionality. (EMS)
7/6/98 (improvement) back-ported the -direct flag from 8.1 into
pkg_mkIndex. This results in pkgIndex.tcl files that contain direct
source or load commands instead of tclPkgSetup commands. (EMS)
7/6/98 (improvement) made changes to the AuxData items structures to support
storage of compiled scripts on disk. Also some related minor changes in
the compilation and execution engine. (EMS)
6/4/98 (enhancement) Added new internal routines to support inserting
and deleting from the stat, access, and open-file-channel mechanisms.
TclAccessInsertProc, TclStatInsertProc, & TclOpenFileChannelInsertProc
insert pointers to such routines; TclAccessDeleteProc, TclStatDeleteProc,
& TclOpenFileChannelDeleteProc delete pointers to such routines. See
the file generic/tclIOUtils.c for more details. (SKS)
7/1/98 (enhancement) Added a new internal C variable
tclPreInitScript. This is a pointer to a string that may hold an
initialization script; If this pointer is non-NULL it is evaluated in
Tcl_Init() prior to the built-in initialization script defined in the
file generic/tclInitScript.h. (SKS)
7/6/98 (bug fix) Removed dead code in PlatformInitExitHandler so that
the TCL_LIBRARY value can be safely patched in binaries. (BW)
7/24/98 (enhancement) Incorporated a new version of auto_mkindex that
can support the [incr Tcl] class structures. This version will index
all procedures in a source file, not just those where "proc" starts
at the beginning of the line. If you want the old behavior, use the
auto_mkindex_old procedure. (MM)
7/24/98 (feature change) Changed the Windows registry key to be
HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, and to store the path
in the default value instead of "Root". Also, this key can be
specified at compile time in case Tcl is being used in a different
context where it needs an alternate library path from the standard Tcl
installation. (SS)
7/24/98 (feature change) Changed the search order for init.tcl. The
tcl_library variable can now be set before calling Tcl_Init to avoid
doing any searches. If it isn't set, then Tcl checks
env(TCL_LIBRARY), the static value set at compile time, an install
directory relative to the executable, a source directory relative to
the executable, and a tcl directory relative to the source heirarchy
containing the executable. See the comment at the top of
generic/tclInitScript.h for more details. (SS)
7/27/98 (config change) Changed the use of the DBGX flag in configure.in
and the makefile to be TCL_DBGX. Users of tclConfig.sh may need to pass
this through their configure files with AC_SUBST. (BW)
729/98 (bug fix) Changed [info body] to return a copy of the body of a
compiled procedure instead of the body itself, to avoid invalidation
of the internal rep and loss of the byte-codes. (EMS)
8/5/98 (bug fix) The platform init code could walk off the end of a
buffer when reading the PkgPath registry value on Windows. (SS)
8/5/98 (Windows makefile change) Introduced a set of macros to deal with
exporting symbols when compiling DLLS on Windows. See win/README for
details. (EMS)
8/5/98 (addendum) Added a second Windows registry key under
HKEY_LOCAL_MACHINE\Software\Scriptics\Tcl\8.0, named "pkgPath".
This is a multi-string value used to initialize the tcl_pkgPath
variable. This is required if extension DLLs are in architecture specific
subdirectories. (SS)
8/6/98 (new feature) Added tcl_findLibrary to init.tcl for use by
extensions, including Tk. This searches in a canonical way for
an extensions library directory and initialization file. (BW)
8/10/98 (bug fix) Imported commands used to get lost if the target
of the import was redefined. Tcl_CreateCommand and Tcl_CreateObjCommand
were updated to restore import links. (Note that if you rename a command,
the import links move to the new name, and if you delete a command then
the import links get lost. These semantics have not changed.) (MC)
-------- Released 8.0.3 to the Tcl Consortium CD-ROM project, 8/10/98 ------
9/3/98 (bug fix) Tcl_Realloc was failing under Windows because the
GlobalReAlloc API was not correctly re-allocating blocks that were
32k+. The fix was to use newer Win32 APIs (HeapAlloc, HeapFree, and
HeapReAlloc.) (BS)
10/5/98 (bug fix) Fixed bug in pkg_mkIndex that caused some files that do
a "package require" of packages in the Tcl libraries to give a warning like
warning: "xx.tcl" provides more than one package ({xx 2.0} {yy 0.3})
and generate a broken pkgIndex.tcl file. (EMS)
10/5/98 (bug fix) Pkg_mkIndex was not doing a case-insensitive comparison
of extensions to determine whether to load or source a file. Thus, under
Windows, MYDLLNAME.DLL was sourced, and mydllname.dll loaded. (EMS)
10/5/98 (new feature) Created a new Tcl_Obj type, "procbody". This object's
internal representation holds a pointer to a Proc structure. Extended
TclCreateProc to take both strings and "procbody". (EMS)
10/13/98 (bug fix) The "info complete" command can now handle strings
with NULLs embedded. Thanks to colin@field.medicine.adelaide.edu.au
for providing this fix. (RJ)
10/13/98 (bug fix) The "lsort -dictionary" command did not properly
handle some numbers starting with 0. Thanks to Richard Hipp
<drh@acm.org> for submitting the fix to Scriptics. (RJ)
10/13/98 (bug fix) The function Tcl_SetListObj was creating an invalid
Tcl_Obj if the list had zero elements (despite what the comments said
it would do). Thanks to Sebastian Wangnick for reporting the
problem. (RJ)
10/20/98 (new feature) Added tcl_platform(debug) element to the
tcl_platform array on Windows platform. The existence of the debug
element of the tcl_platform array indicates that the particular Tcl
shell has been compiled with debug information. Using
"info exists tcl_platform(debug)" a Tcl script can direct the
interpreter to load debug versions of DLLs with the load
command. (SKS)
10/20/98 (feature change) The Makefile and configure scripts have been
changed for IRIX to build n32 binaries instead of the old 32 abi
format. If you have extensions built with the o32 abi's you will need
to update them to n32 for them to work with Tcl. (RJ)
*** POTENTIAL INCOMPATIBILITY ***
10/23/98 (bug fix) tcl_findLibrary had a stray ] in one of the
pathnames it searched for the initialization script. tclInitScript.h
was incorrectly adding the parent of tcl_library to tcl_pkgPath. This
logic was moved into init.tcl, and the initialization of auto_path was
documented. Thanks to Donald Porter and Tom Silva for related
patches. (BW)
10/29/98 (bug fix) Fixed Tcl_NotifyChannel to use Tcl_Preserve instead
of Tcl_RegisterChannel so that 1) unregistered channels do not get
closed after their first fileevent, and 2) errors that occur during
close in a fileevent script are actually reflected by the close
command. (BW)
10/30/98 (bug fix) Overhaul of pkg_mkIndex to deal with transitive
package requires and packages split among scripts and binary files.
Also fixed ommision of global for errorInfo in tcl_findLibrary. (BW)
11/08/98 (bug fix) Fixed the resource command to always detect
the case where a file is opened a second time with the same
permissions. IM claims that this will always cause the same
FileRef to be returned, but in MacOS 8.1+, this is no longer the case,
so we have to test for this explicitly. (JI)
11/10/98 (feature change) When compiling with Metrowerk's MSL, use the
exit function from MSL rather than ExitToShell. This allows MSL to
clean up its temporary files. Thanks to Vince Darley for this
improvement. (JI)
----------------- Released 8.0.4, 11/19/98 -------------------------
11/20/98 (bug fix) Handle possible NULL return in TclGetStdFiles. (RJ)
11/20/98 (bug fix) The dltests would not build on SGI. They reported
that you could not mix n32 with 032 binaries. The configure script
has been modified to get the EXTRA_CFLAGS from the tcl configure
script. [Bug id: 840] (RJ)
12/3/98 (bug fix) Windows NT creates sockets so they are inheritable
by default. Fixed socket code so it turns off this bit right after
creation so sockets aren't kept open by exec'ed processes. [Bug: 892]
Thanks to Kevin Kenny for this fix. (SS)
1/11/98 (bug fix) On HP, "info sharedlibextension" was returning
empty string on static apps. It now always returns ".sl". (RJ)
1/28/99 (configure change) Now support -pipe option on gcc. (RJ)
2/2/99 (bug fix) Fixed initialization problem on Windows where no
searching for init.tcl would be performed if the registry keys were
missing. (stanton)
2/2/99 (bug fix) Added support for HKEY_PERFORMANCE_DATA and
HKEY_DYN_DATA keys in the "registry" command. (stanton)
2/2/99 (bug fix) ENOTSUP and EOPNOTSUPP clashed on some Linux
variants. (stanton)
2/2/99 (enhancement) The "open" command has been changed to use the
object interfaces. (stanton)
2/2/99 (bug fix) In some cases Tcl would crash due to an overflow of
the exception stack resulting from a missing byte code in some
expressions. (stanton)
2/2/99 (bug fix) Changed configure so Linux and IRIX shared libraries
are linked with the system libraries. (stanton)
2/2/99 (bug fix) Added support for BSDI 4.x (BSD/OS-4*) to the
configure script. (stanton)
2/2/99 (bug fix) Fixed bug where upvar could resurrect a namespace
variable after the namespace had been deleted. (stanton)
2/2/99 (bug fix) In some cases when creating variables, the
interpreter result was being modified even if the TCL_LEAVE_ERR_MSG
flag was set. (stanton)
2/2/99 (bug fix & new feature) Changed the socket drivers to properly
handle failures during an async socket connection. Added a new
fconfigure option "-error" to retrieve the failure message. See the
socket.n manual entry for details. (stanton)
2/2/99 (bug fix) Deleting a renamed interp alias could result in a
panic. (stanton)
2/2/99 (feature change/bug fix) Changed the behavior of "file
extension" so that it splits at the last period. Now the extension of
a file like "foo..o" is ".o" instead of "..o" as in previous versions.
*** POTENTIAL INCOMPATIBILITY ***
----------------- Released 8.0.5, 3/9/99 -------------------------
======== Changes for 8.0 go above this line ========
======== Changes for 8.1 go below this line ========
6/18/97 (new feature) Tcl now supports international character sets:
- All C APIs now accept UTF-8 strings instead of iso8859-1 strings,
wherever you see "char *", unless explicitly noted otherwise.
- All Tcl strings represented in UTF-8, which is a convenient
multi-byte encoding of Unicode. Variable names, procedure names,
and all other values in Tcl may include arbitrary Unicode characters.
For example, the Tcl command "string length" returns how many
Unicode characters are in the argument string.
- For Java compatibility, embedded null bytes in C strings are
represented as \xC080 in UTF-8 strings, but the null byte at the end
of a UTF-8 string remains \0. Thus Tcl strings once again do not
contain null bytes, except for termination bytes.
- For Java compatibility, "\uXXXX" is used in Tcl to enter a Unicode
character. "\u0000" through "\uffff" are acceptable Unicode
characters.
- "\xXX" is used to enter a small Unicode character (between 0 and 255)
in Tcl.
- Tcl automatically translates between UTF-8 and the normal encoding for
the platform during interactions with the system.
- The fconfigure command now supports a -encoding option for specifying
the encoding of an open file or socket. Tcl will automatically
translate between the specified encoding and UTF-8 during I/O.
See the directory library/encoding to find out what encodings are
supported (eventually there will be an "encoding" command that
makes this information more accessible).
- There are several new C APIs that support UTF-8 and various encodings.
See Utf.3 for procedures that translate between Unicode and UTF-8
and manipulate UTF-8 strings. See Encoding.3 for procedures that
create new encodings and translate between encodings. See
ToUpper.3 for procedures that perform case conversions on UTF-8
strings.
9/18/97 (enhancement) Literal objects are now shared by the ByteCode
structures created when compiled different scripts. This saves up to 45%
of the total memory needed for all literals. (BL)
9/24/97 (bug fixes) Fixed Tcl_ParseCommand parsing of backslash-newline
sequences at start of command words. Suppressed Tcl_EvalDirect error logging
if non-TCL_OK result wasn't an error. (BL)
10/17/97 (feature enhancement) "~username" now refers to the users' home
directory on Windows (previously always returned failure). (CCS)
10/20/97 (implementation change) The Tcl parser has been completely rewritten
to make it more modular. It can now be used to parse a script without actually
executing it. The APIs for the new parser are not correctly exported, but
they will eventually be exported and augmented with Tcl commands so that
Tcl scripts can parse other Tcl scripts. (JO)
10/21/97 (API change) Added "flags" argument to Tcl_EvalObj, removed
Tcl_GlobalEvalObj procedure. Added new procedures Tcl_Eval2 and
Tcl_EvalObjv. (JO)
*** POTENTIAL INCOMPATIBILITY ***
10/22/97 (API change) Renamed Tcl_ObjSetVar2 and Tcl_ObjGetVar2 to
Tcl_SetObjVar2 and Tcl_GetObjVar2 (for consistency with other C APIs)
and changed the name arguments to be strings instead of objects. (JO)
*** POTENTIAL INCOMPATIBILITY ***
10/27/97 (enhancement) Bytecode compiler rewritten to use the new Tcl
parser. (BL)
11/3/97 (New routines) Added Tcl_AppendObjToObj, which appends the
string rep of one Tcl_Obj to another. Added Tcl_GetIndexFromObjStruct,
which is similar to Tcl_GetIndexFromObj, except that you can give an
offset between strings. This allows Tcl_GetIndexFromObjStruct to be
called with a table of records which have strings in them. (SRP)
12/4/97 (enhancement) New Tcl expression parser added. Added new procedure
Tcl_ParseExpr and new token types TCL_TOKEN_SUB_EXPR and
TCL_TOKEN_OPERATOR. Expression compiler is reimplemented to use this
parser. (BL)
12/9/97 (bug fix) Tcl_EvalObj() increments/decrements the refcount of the
script object to prevent the object from deleting itself while in the
middle of being evaluated. (CCS)
12/9/97 (bug fix) Memory leak in Tcl_GetsObjCmd(). (CCS)
12/11/97 (bug fix) Environment array leaked memory when compiled with
Visual C++. (SS)
12/11/97 (bug fix) File events and non-blocking I/O did not work on
pipes under Windows. Changed to use threads to achieve non-blocking
behavior. (SS)
12/18/97 (bug fixes) Fixed segfault in "namespace import"; importing a
procedure that causes a cycle now returns an error. Modified "info procs",
"info args", "info body", and "info default" to return information about
imported procedures as well as procedures defined in a namespace. (BL)
12/19/97 (enhancement) Added new Tcl_GetString() procedure that can be used
in place of Tcl_GetStringFromObj() if the string representation's length
isn't needed. (BL)
12/18/97 (bug fix) In the opt argument parsing package: if the description
had only flags, the "too many arguments" case was not detected. The default
value was not used for the special "args" ending argument. (DL)
1/7/98 (clean up) Moved everything not absolutly necessary out of init.tcl
procs now in auto.tcl and package.tcl can be autoloaded if needed. (DL)
1/7/98 (enhancement) tcltest made at install time will search for it's
init.tcl where it is, even when using virtual path compilation. (DL)
1/8/98 (os bug workaround) when needed, using a replacement for memcmp so
string compare "char with high bit set" "char w/o high bit set" returns
the expected value on all platforms. (DL)
1/8/98 (unix portability/configure) building from .../unix/targetName/
subdirectories and simply using "../configure" should now work fine. (DL)
1/14/98 (enhancement) Added new regular expression package that
supports AREs, EREs, and BREs. The new package includes new escape
characters, meta-syntax, and character classes inside brackets.
Regexps involving backslashes may behave differently. (MH)
*** POTENTIAL INCOMPATIBILITY ***
1/16/98 (os workaround) Under windows, "file volume" was causing chatter
and/or several seconds of hanging when querying empty floppy drives.
Changed implementation to call an empirically-derived function that doesn't
cause this. (CCS)
1/16/98 (enhancement) Converted regular expressions to a Tcl_Obj type so
their compiled form gets cached automatically. Reduced NSUBEXP from 100
to 20. (BW)
1/16/98 (documentation) Change unclear documentation and comments for
functions like Tcl_TranslateFileName() and Tcl_ExternalToUtfDString(). Now
it explicitly says they take an uninitialized or free DString. A DString
that is "empty" or "not holding anything" could have been interpreted as one
currently with a zero length, but with a large dynamically allocated buffer.
(CCS)
----------------- Released 8.1a1, 1/22/98 -----------------------
1/28/98 (new feature) Added a "-direct" optional flag to pkg_mkIndex
to generate direct loading package indexes (such those you need
if you use namespaces and plan on using namespace import just after
package require). pkg_mkIndex still has limitations regarding
package dependencies but errors are now ignored and with -direct, correct
package indexes can be generated even if there are dependencies as long
as the "package provide" are done early enough in the files. (DL)
1/28/98 (enhancement) Performance tuning of regexp and regsub. (CCS)
1/28/98 (bug fix) regexp and regsub with "-indices" returned the byte-offsets
of the characters in the UTF-8 representation, not the character offsets
themselves. (CCS)
1/28/98 (bug fix) "clock format 0 -format %Z -gmt 1" would return the local
timezone string instead of "GMT" on Solaris and Windows.
1/28/98 (bug fix) Restore tty settings when closing serial device on Unix.
This is good behavior when closing real serial devices, essential when
closing the pseudo-device /dev/tty because the user's terminal settings
would be left useless, in raw mode, when tcl quit. (CCS)
1/28/98 (bug fix) Tcl_OpenCommandChannel() was modifying the contents of the
argv array passed to it, causing problems for any caller that wanted to
continue to use the argv array after calling Tcl_OpenCommandChannel(). (CCS)
2/1/98 (bug fix) More bugs with %Z in format string argument to strftime():
1. Borland always returned empty string.
2. MSVC always returned the timezone string for the current time, not the
timezone string for the specified time.
3. With MSVC, "clock format 0 -format %Z -gmt 1" would return "GMT" the first
time it was called, but would return the current timezone string on all
subsequent calls. (CCS)
2/1/98 (bug fix) "file stat" was broken on Windows.
1. "file stat" of a root directory (local or network) or a relative path that
resolved to a root directory (c:. when in pwd was c:/) was returning error.
2. "file stat" on a regular file (S_IFREG), the st_mode was sign extended to
a negative int if the platform-dependant type "mode_t" was declared as a
short instead of an unsigned short.
3. "file stat" of a network directory, the st_dev was incorrectly reported
as the id of the last accessed local drive rather than the id of the
network drive. (CCS)
2/1/98 (bug fix) "file attributes" of a relative path that resolved to a
root directory was returning error. (CCS)
2/1/98 (bug fix) Change error message when "file attribute" could not
determine the attributes for a file. Previously it would return different
error messages on Unix vs. Windows vs. Mac. (CCS)
2/4/98 (bug fixes) Fixed several instances of bugs where the parser/compiler
would reach outside the range of allocated memory. Improved the array
lookup algorithm in set compilation. (DL)
2/5/98 (change) The TCL_PARSE_PART1 flag for Set/Get(Obj)Var2 C APIs is now
deprecated and ignored. The part1 is always parsed when the part2 argument
is NULL. This is to avoid a pattern of errors for extension writers converting
from string based Tcl_SetVar() to new Tcl_SetObjVar2() and who could easily
forget to provide the flag and thus get code working for normal variables
but not for array elements. The performance hit is minimal. A side effect
of that change is that is is no longer possible to create scalar variables
that can't be accessed by tcl scripts because of their invalid name
(ending with parenthesis). Likewise it is also parsed and checked to
ensure that you don't create array elements of array whose name is a valid
array element because they would not be accessible from scripts anyway.
Note: There is still duplicate array elements parsing code. (DL)
*** POTENTIAL INCOMPATIBILITY ***
2/11/98 (bug fix) Sharing objects between interps, such as by "interp
eval" or "send" could cause a crash later when dereferencing an interp
that had been deleted, given code such as:
set a {set x y}
interp create foo
interp eval foo $a
interp delete foo
unset a
Interp "foo" was gone, but "a" had a internal rep consisting of bytecodes
containing a dangling pointer to "foo". Unsetting "a" would attempt to
return resources back to "foo", causing a crash as random memory was
accessed. The lesson is that that if an object's internal rep depends on
an interp (or any other data structure) it must preserve that data in
some fashion. (CCS)
2/11/98 (enhancement) The "interp" command was returning inconsistent error
messages when the specified slave interp could not be found. (CCS)
2/11/98 (bug fix) Result codes like TCL_BREAK and TCL_CONTINUE were not
propagating through the master/slave interp boundaries, such as "interp
eval" and "interp alias". TCL_OK, TCL_ERROR, and non-standard codes like
teh integer 57 work. There is still a question as to whether TCL_RETURN
can/should propagate. (CCS)
2/11/98 (bug fix) TclCompileScript() was derefering memory 1 byte before
start of the string to compile, looking for ']'. (CCS,DL)
2/11/98 (bug fix) Tcl_Eval2() was derefering memory 1 byte before start
of the string to eval, looking for ']'. (CCS,DL)
2/11/98 (bug fix) Compiling "set a(b" was running off end of string. (CCS,DL)
2/11/98 (bug fix) Windows initialization code was dereferencing
uninitialized memory if TCL_LIBRARY environment didn't exist. (CCS)
2/11/98 (bug fix) Windows "registry" command was dereferencing
uninitialized memory when constructing the $errorCode for a failed
registry call. (CCS)
2/11/98 (enhancement) Eliminate the TCL_USE_TIMEZONE_VAR definition from
configure.in, because it was the same information as the already existing
HAVE_TM_ZONE definition. The lack of HAVE_TM_ZONE is used to work around a
Solaris and Windows bug where "clock format [clock sec] -format %Z -gmt 1"
produces the local timezone string instead of "GMT". (CCS)
2/11/98 (bug fix) Memleaks and dereferencing of uninitialized memory in
regexp if an error occurred while compiling a regular expression. (CCS).
2/18/98 (new feature) Added mutexes and thread local storage in order
to make Tcl thread safe. For testing purposes, there is a testthread
command that creates a new thread and an interpreter inside it. See
thread.test for examples, but this script-level interface is not fixed.
Each thread has its own notifier instance to manage its own events,
and threads can post messages to each other's message queue.
This uses pthreads on UNIX, and native thread support on other platforms.
You enable this by configuring with --enable-threads. Note that at
this time *Tk* is still not thread safe. Special thanks to
Richard Hipp: his earlier implementation inspired this work. (BW, SS, JI)
2/18/98 (hidden feature change) The way the env() array is shared among
interpreters changed. Updates to env used to trigger write traces in
other interpreters. This undocumented feature is no longer implemented.
Instead, variable tracing is used to keep the C-level environ array in sync
with the Tcl-level env array. This required adding TCL_TRACE_ARRAY support
to Tcl_TraceVar2 so that array names works properly. (BW)
*** POTENTIAL INCOMPATIBILITY ***
2/18/98 (enhancement) Conditional compilation for unix systems (e.g.,
IRIX, SCO) that use f_bsize instead of st_blksize to determine disk block
size. (CCS)
2/23/98 (bug fix) Fixed the emulation of polling selects in the threaded
version of the Unix notifier. The bug was showing up on a multiprocessor
as starvation of the notifier thread. (BW)
----------------- Released 8.1a2, Feb 23 1998 -----------------------
9/22/98 (bug fix) Changed the value of TCL_TRACE_ARRAY so it no longer
conflicts with the deprecated TCL_PARSE_PART1 flag. This should
improve portability of C code. (stanton)
10/6/98 (bug fix) The compile procedure for "if" incorrectly attempted
to match against the literal string "if", resulting in a stack
overflow when "::if" was compiled. It also would incorrectly accept
"if" instead of "elsif" in later clauses. (stanton)
10/15/98 (new feature) Added a "totitle" subcommand to the "string"
command to convert strings to capitalize the first character of a string
and lowercase all of the other characters. (stanton)
10/15/98 (bug fix) Changed regexp and string commands to properly
handle case folding according to the Unicode character
tables. (stanton)
10/21/98 (new feature) Added an "encoding" command to facilitate
translations of strings between different character encodings. See
the encoding.n manual entry for more details. (stanton)
11/3/98 (bug fix) The regular expression character classification
syntax now includes Unicode characters in the supported
classes. (stanton)
11/6/98 (bug fix) Variable traces were causing crashes when upvar
variables went out of scope. [Bug: 796] (stanton)
11/9/98 (bug fix) "format" now correctly handles multibyte characters
in %s format strings. (stanton)
11/10/98 (new feature) "regexp" now accepts three new switches
("-line", "-lineanchor", and "-linestop") that control how regular
expressions treat line breaks. See the regexp manual entry for more
details. (stanton)
11/17/98 (bug fix) "scan" now correctly handles Unicode
characters. (stanton)
11/17/98 (new feature) "scan" now supports XPG3 position specifiers
and the "%n" conversion character. See the "scan" manual entry for
more details. (stanton)
11/17/98 (bug fix) The Tcl memory allocator now returns 8-byte aligned
chunks of memory which improves performance on Windows and avoids
crashes on other platforms. [Bug: 834] (stanton)
11/23/98 (bug fix) Applied various regular expression performance bug
fixes supplied by Henry Spencer. (stanton)
11/30/98 (bug fix) Fixed various thread related race conditions. [Bug:
880 & 607] (stanton)
11/30/98 (bug fix) Fixed a number of memory overflow and leak
bugs. [Bug: 584] (stanton)
12/1/98 (new feaure) Added support for Korean encodings. (stanton)
12/1/98 (feature change) Changed the Tcl_EvalObjv interface to remove
the string and length arguments.
*** POTENTIAL INCOMPATIBILITY with previous alpha releases ***
12/2/98 (bug fix) Fixed various bugs related to line feed
translation. [Bug: 887] (stanton)
12/4/98 (new feature) Added a message catalog facility to help with
localizing Tcl scripts. Thanks to Mark Harrison for contributing the
initial implementation of the "msgcat" package. (stanton)
12/7/98 (bug fix) The memory allocator was failing to update the
block list for large memory blocks that were reallocated into a
different address. [Bug: 933] (stanton)
----------------- Released 8.1b1, Dec 10 1998 -----------------------
12/22/98 (performance improvement) Improved the -command option of the
lsort command to better use the object system for improved
performance (about 5x speed up). Thanks to Syd Polk for suppling the
patch. [RFE: 726] (rjohnson)
2/10/99 (bug fix) Restored the Tcl_ObjSetVar2/Tcl_ObjGetVar2
interfaces from 8.0 and renamed the Tcl_GetObjVar2/Tcl_SetObjVar2
interfaces to Tcl_GetVar2Ex and Tcl_SetVar2Ex. This should provide
better compatibility with 8.0. (stanton)
*** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases ***
2/10/99 (bug fix) Made the eval interfaces compatible with 8.0 by
renaming Tcl_EvalObj to Tcl_EvalObjEx, renaming Tcl_Eval2 to
Tcl_EvalEx and restoring Tcl_EvalObj and Tcl_GlobalEvalObj interfaces
so they match Tcl 8.0. (stanton)
*** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases ***
2/25/99 (bug fix/new feature) On Windows, the channel drivers for
consoles and serial ports now completely support file events. (redman)
3/5/99 (bug fix) Integrated patches to fix various configure problems
that affected HP-UX-11, 64-bit IRIX, Linux, and Solaris. (stanton)
3/9/99 (bug fix) Integrated various AIX related patches to improve
support for shared libraries. (stanton)
3/9/99 (new feature) Added tcl_platform(user) to provide a portable
way to get the name of the current user. (welch)
3/9/99 (new feature) Integrated the stub library mechanism contributed
by Jan Nijtmans, Paul Duffin, and Jean-Claude Wippler. This feature
should make it possible to write extensions that support multiple
versions of Tcl simultaneously. It also makes it possible to
dynamically load extensions into statically linked interpreters. This
patch includes the following changes:
- Added a Tcl_InitStubs() interface
- Added Tcl_PkgProvideEx, Tcl_PkgRequireEx, Tcl_PkgPresentEx,
and Tcl_PkgPresent.
- Added va_list versions of all VARARGS functions so they can be
invoked from wrapper functions.
See the manual for more information. (stanton)
3/10/99 (feature change) Replaced Tcl_AlertNotifier with
Tcl_ThreadAlert since the Tcl_AlertNotifier function relied on passing
internal data structures. (stanton)
*** POTENTIAL INCOMPATIBILITY with previous alpha/beta releases ***
3/10/99 (new feature) Added a Tcl_GetVersion API to make it easier to
check the Tcl version and patch level from C. (redman)
3/14/99 (feature change) Tried to unify the TclpInitLibrary path
routines to look in similar places from Windows to UNIX. The new
library search path is: TCL_LIBRARY, TCL_LIBRARY/../tcl8.1, relative
to DLL (Windows Only) relative to installed executable, relative to
develop executable, and relative to compiled-in in location (UNIX
Only.) This fix included:
- Defining a TclpFindExecutable
- Moving Tcl_FindExecutable to a common area in tclEncoding.c
- Modifying the TclpInitLibraryPath routines.
(surles)
3/14/99 (feature change) Added hooks for TclPro Wrapper to initialize
the location of the encoding files and libraries. This fix included:
- Adding the TclSetPerInitScript routine.
- Modifying the Tcl_Init routines to evaluate the non-NULL
pre-init script.
- Adding the Tcl_SetdefaultEncodingDir and Tcl_GetDefaultEncodingDir
routines.
- Modifying the TclpInitLibrary routines to append the default
encoding dir.
(surles)
3/14/99 (feature change) Test suite now uses "test" namespace to
define the test procedure and other auxiliary procedures as well as
global variables.
- Global array testConfige is now called ::test::testConfig.
- Global variable VERBOSE is now called ::test::verbose, and
::test::verbose no longer works with numerical values. We've
switched to a bitwise character string. You can set
::test::verbose by using the -verbose option on the Tcl command
line.
- Global variable TESTS is now called ::test::matchingTests, and
can be set on the Tcl command line via the -match option.
- There is now a ::test::skipTests variable (works similarly to
::test::matchTests) that can be set on the Tcl command line via
the -match option.
- The test suite can now be run in any working directory. When
you run "make test", the working directory is nolonger switched
to ../tests.

*** POTENTIAL INCOMPATIBILITY ***
--------------- Released 8.1b2, March 16, 1999 ----------------------
3/18/99 (bug fix) Fixed missing/incorrect characters in shift-jis table
(stanton)
3/18/99 (feature change) The glob command ignores the
FS_CASE_IS_PRESERVED bit on file systesm and always returns
exactly what it gets from the system. (stanton)
*** POTENTIAL INCOMPATIBILITY ***
3/19/99 (new feature) Added support for --enable-64bit. For now,
this is only supported on Solaris 7 64bit (SunOS 5.7) using the Sun
compiler. (redman)
3/23/99 (bug fix) Fixed fileevents and gets on Windows consoles and
serial devices so that non-blocking channels do not block on partial
input lines. (redman)
3/23/99 (bug fix) Added a new Tcl_ServiceModeHook interface.
This is used on Windows to avoid the various problems that people
have been seeing where the system hangs when tclsh is running
outside of the event loop. As part of this, renamed
TclpAlertNotifier back to Tcl_AlertNotifier since it is public.
(stanton)
3/23/99 (feature change) Test suite now uses "tcltest" namespace to
define the test procedure and other auxiliary procedures as well as
global variables. The previously chosen "test" namespace was thought
to be too generic and likely to create conflits.
(hirschl)
*** POTENTIAL INCOMPATIBILITY ***
3/24/99 (bug fix) Make sockets thread safe on Windows.
(redman)
3/24/99 (bug fix) Fix cases where expr would incorrect return
a floating point value instead of an integer. (stanton)
3/25/99 (bug fix) Added ASCII to big5 and gb2312 encodings.
(stanton)
3/25/99 (feature change) Changed so aliases are invoked at current
scope in the target interpreter instead of at the global scope. This
was an incompatibility introduced in 8.1 that is being removed.
(stanton)
*** POTENTIAL INCOMPATIBILITY with previous beta releases ***
3/26/99 (feature change) --enable-shared is now the default and build
Tcl as a shared library; specify --disable-shared to build a static Tcl
library and shell.
*** POTENTIAL INCOMPATIBILITY ***
3/29/99 (bug fix) Removed the stub functions and changed the stub
macros to just use the name without params. Pass &tclStubs into the
interp (don't use tclStubsPtr because of collisions with the stubs on
Solaris). (redman)
3/30/99 (bug fix) Loadable modules are now unloaded at the last
possible moment during Tcl_Finalize to fix various exit-time crashes.
(welch)
3/30/99 (bug fix) Tcl no longer calls setlocale(). It looks at
env(LANG) and env(LC_TYPE) instead. (stanton)
4/1/99 (bug fix) Fixed the Ultrix multiple symbol definition problem.
Now, even Tcl includes a copy of the Tcl stub library. (redman)
4/1/99 (bug fix) Internationalized the registry package.
4/1/99 (bug fix) Changed the implemenation of Tcl_ConditionWait and
Tcl_ConditionNotify on Windows. The new algorithm eliminates a race
condition and was suggested by Jim Davidson. (welch)
4/2/99 (new apis) Made various Unicode utility functions public.
Tcl_UtfToUniCharDString, Tcl_UniCharToUtfDString, Tcl_UniCharLen,
Tcl_UniCharNcmp, Tcl_UniCharIsAlnum, Tcl_UniCharIsAlpha,
Tcl_UniCharIsDigit, Tcl_UniCharIsLower, Tcl_UniCharIsSpace,
Tcl_UniCharIsUpper, Tcl_UniCharIsWordChar, Tcl_WinUtfToTChar,
Tcl_WinTCharToUtf (stanton)
4/2/99 (feature change) Add new DDE package and removed the Tk
send command from the Windows version. Changed DDE-based send
code into "dde eval" command. The DDE package can be loaded
into tclsh, not just wish. Windows only. (redman)
4/5/99 (bug fix) Changed safe-tcl so that the encoding command
is an alias that masks out the "encoding system" subcommand.
(redman)
4/5/99 (bug fix) Configure patches to improve support for
OS/390 and BSD/OS 4.*. (stanton)
4/5/99 (bug fix) Fixed crash in the clock command that occurred
with negative time values in timezones east of GMT. (stanton)
4/6/99 (bug fix) Moved the "array set" C level code into a common
routine (TclArraySet). The TclSetupEnv routine now uses this API to
create an env array w/ no elements. This fixes the bug caused when
every environ varaible is removed, and the Tcl env variable is
synched. If no environ vars existed, the Tcl env var would never be
created. (surles)
4/6/99 (bug fix) Made the Env module I18N compliant. (surles)
4/6/99 (bug fix) Changed the FindVariable routine to TclpFindVariable,
that now does a case insensitive string comparison on Windows, and not
on UNIX. (surles)
--------------- Released 8.1b3, April 6, 1999 ----------------------
4/9/99 (bug fix) Fixed notifier deadlock situation when the pipe used
to talk back notifier thread is filled with data. Found as a result of the
focus.test for Tk hanging. (redman)
4/13/99 (bug fix) Fixed bug where socket -async combined with
fileevent for writing did not work under Windows NT. (redman)
4/13/99 (encoding fix) Restored the double byte definition of GB2312
and added the EUC-CN encoding. EUC-CN is a variant of GB2312 that
shifts the characters into bytes with the high bit set and includes
ASCII as a subset. (stanton)
4/27/99 (bug fix) Added 'extern "C" {}' block around the stub table
pointer declaration so the stub library can be used from C++. (stanton)
--------------- Released 8.1 final, April 29, 1999 ----------------------
4/22/99 (bug fix) Changed Windows NT socket implementation to avoid
creating a communication window. This avoids the problem where the
system hangs waiting for tclsh to respond to a system-wide synchronous
broadcast (e.g. if you change system colors). (redman)
4/22/99 (bug fix) Added call to TclWinInit from TclpInitPlatform when
building a static library since DllMain will not be invoked. This
could break old code that explicitly called TclWinInit, but should be
simpler in the long run. (stanton)
*** POTENTIAL INCOMPATIBILITY ***
4/23/99 (bug fix) Added support for the koi8-r Cyrillic
encoding. [Bug: 1771] (stanton)
4/28/99 (bug fix) Changed internal Tcl_Obj usage to avoid freeing the
internal representation after the string representation has been
freed. This makes it easier to debug extensions. (stanton)
4/30/99 (bug fix) Fixed a memory leak in CommandComplete. (stanton)
5/3/99 (bug fix) Fixed a bug where the Tcl_ObjType was not being set
in a duplicated Tcl_Obj. [Bug: 1975, 2047] (stanton)
5/3/99 (bug fix) Changed Tcl_ParseCommand to avoid modifying eval'ed
strings that are already null terminated. [Bug: 1793] (stanton)
5/3/99 (new feature) Applied Jeff Hobbs's string patch which includes
the following changes:
- added new subcommands: equal, repeat, map, is, replace
- added -length option to "string compare|equal"
- added -nocase option to "string compare|equal|match"
- string and list indices can be an integer or end?-integer?.
- added optional first and last index args to string toupper, et al.
See the string.n manual entry for more details about the new string
features. [Bug: 1845] (stanton)
5/6/99 (new feature) Added Tcl_UtfNcmp and Tcl_UtfNcasecmp to make Utf
string comparision easier. (stanton)
5/7/99 (bug fix) Improved OS/390 support. [Bug: 1976, 1997] (stanton)
5/12/99 (bug fix) Changed Windows initialization code to avoid using
GetUserName system call in favor of the env(USERNAME) variable. This
provides a significant startup speed improvement. (stanton)
5/12/99 (bug fix) Replaced the per-interpreter regexp cache with a
per-thread cache. Changed the Regexp object to take advantage of this
extra cache. Added a reference count to the TclRegexp type so regexps
can be shared by multiple objects. Removed the per-interp regexp cache
from the interpreter. Now regexps can be used with no need for an
interpreter. This set of changes should provide significant speed
improvements for many Tcl scripts. [Bug: 1063] (stanton)
5/14/99 (bug fix) Durining initialization on Unix, Tcl now extracts the
encoding subfield from the LANG/LC_ALL environment variables in cases
where the locale is not found in the built-in locale table. It also
attempts to initialize the locale subsystem so X11 is happy. [Bug: 1989]
(stanton)
5/14/99 (bug fix) Applied the patch to fix 100-year and 400-year
boundaries in leap year code, from Isaac Hollander. [Bug: 2066] (redman)
5/14/99 (bug fix) Fixed a crash caused by a failure to reset the result
before evaluating the test expression in an uncompiled for
statement. (stanton)
5/18/99 (bug fix) Modified initialization code on Windows to avoid
inherenting closed or invalid channels. If the standard input is
anything other than a console, file, serial port, or pipe, then we fall
back to the standard Tk window console. (stanton)
5/19/99 (bug fix) Added an extern "C" block around the entire tcl.h
header file to avoid C++ linkage issues. (redman)
5/19/99 (new feature) Applied Jeff Hobb's patch to add
Tcl_StringCaseMatch to support case insensitive glob style matching and
Tcl_UniCharIs* character classification functions. (stanton)
5/20/99 (bug fix) Added the directory containing the executuble and the
../lib directory relative to that to the auto_path variable. (redman)
--------------- Released 8.1.1, May 25, 1999 ----------------------
5/21/99 (bug fix) Fixed launching command.com on Win95/98, no longer
hangs. [Bug: 2105] (redman)
5/28/99 (bug fix) Fixed bug where dde calls were being passed an
invalid dde handle. [Bug: 2124] (stanton)
6/1/99 (bug fix) Small configure.in patches. [Bug: 2121] (stanton)
6/1/99 (bug fix) Applied latest regular expression patches to fix an
infinite loop bug and add support for testing whether a string could
match with additional input. [Bug: 2117] (stanton)
6/2/99 (bug fix) Fixed incorrect computation of relative ordering in
Utf case-insensitive comparison. [Bug: 2135] (stanton)
6/3/99 (bug fix) Fxied bug where string equal/compare -nocase
reported wrong result on null strings. [Bug: 2138] (stanton)
6/4/99 (new feature) Windows build now uses Cygwin tools plus GNU
make and autoconf to build static/dynamic and debug/nodebug. (stanton)
6/7/99 (new feature) Optimized string index, length, range, and
append commands. Added a new Unicode object type. (hershey)
6/8/99 (bug fix) Rolled back Windows socket driver to 8.1.0
version. (stanton)
6/9/99 (new feature) Added Tcl_RegExpMatchObj and Tcl_RegExpGetInfo
to public Tcl API, these functions are needed by Expect. Changed
tools/genStubs.tcl to always write output in LF mode. (stanton)
6/14/99 (new feature) Merged string and Unicode object types. Added
new public Tcl API functions: Tcl_NewUnicodeObj, Tcl_SetUnicodeObj,
Tcl_GetUnicode, Tcl_GetUniChar, Tcl_GetCharLength, Tcl_GetRange,
Tcl_AppendUnicodeToObj. (hershey)
6/16/99 (new feature) Changed to conform to TEA specification, added
tcl.m4 and aclocal.m4 macro libraries for configure. (wart)
6/17/99 (new feature) Added new regexp interfaces: -expanded, -line,
-linestop, and -lineanchor switches. Renamed Tcl_RegExpMatchObj to
Tcl_RegExpExecObj and added new Tcl_RegExpMatchObj that is equivalent
to Tcl_RegExpMatch. Added public macros for regexp flags. Added
REG_BOSONLY flag to allow Expect to iterate through a string and only
find matches that start at the current position within the
string. (stanton)
6/21/99 (bug fix) Fixed memory leak in TclpThreadCreate where thread
attributes were not being released. [Bug: 2254] (stanton)
6/23/99 (new feature) Updated Unicode character tables to reflect
Unicode 2.1 data. (stanton)
6/25/99 (new feature) Fixed bugs in non-greedy quantifiers for regular
expression code. (stanton)
6/25/99 (new feature) Added initial implementation of new Tcl test
harness package. Modified test files to use new tcltest package.
(jenn)
6/26/99 (new feature) Applied patch from Peter Hardie to add poke
command to dde and changed the dde package version number to
1.1. (redman)
6/28/99 (bug fix) Applied patch from Peter Hardie to fix problem in
Tcl_GetIndexFromObj() when the key being passed is the empty string.
[Bug: 1738] (redman)
6/29/99 (new feature) Added options to tcltest package: -preservecore,
-limitconstraints, -help, -file, -notfile, and flags. (jenn)
7/3/99 (new feature) Changed parsing of variable names to allow empty
array names. Now "$(foo)" is a variable reference. Previously you
had to use something line $::(foo), which is slower. This change was
requested by Jean-Luc Fontaine for his STOOOP package. (welch)
7/3/99 (new feature) Added Tcl_SetNotifier (public API) and
associated hook points in the notifiers to be able to replace the
notifier calls at runtime. The Xt notifier and test program use this
hook. (welch)
7/3/99 (new feature) Added a new variant of the "Trf core patch" from
Andreas Kupries that adds new C APIs Tcl_StackChannel,
Tcl_UnstackChannel, and Tcl_GetStackedChannel. This allows the Trf
extension to work without applying patches to the Tcl core. (welch)
7/6/99 (new feature) Added -timeout option to http.tcl to handle
timeouts that occur during connection attempts to hosts that are
down. (welch)
7/6/99 (bug fix) Applied new implementation of the Windows serial
port driver from Rolf Schroedter that fixes reading only one byte from
the port at a time. Uses polling every 10ms to implement
fileevents. [Bug: 1980 2217] (redman)
7/8/99 (bug fix) Applied fix for bug in DFA state caching under
lookahead conditions (regular expressions). [Bug: 2318] (stanton)
7/8/99 (bug fix) Fixed bug in string range bounds checking
code. (stanton)
--------------- Released 8.2b1, July 14, 1999 ----------------------
7/16/99 (bug fix) Added Tcl_SetNotifier to stub table. [Bug: 2364]
Added check for Alpha/Linux to correct the IEEE floating point flag,
patch from Don Porter. (redman)
7/20/99 (bug fix) Merged 8.0.5 code to handle tcl_library properly,
also fixed a bug that caused TCL_LIBRARY to be ignored. (hershey)
7/21/99 (bug fix) Implemented modified socket driver for Windows that
uses a thread to manage the socket event window. Code works the same
on all supported versions of Windows and was based on original 8.1.0
code. [Bug: 2178 2256 2259 2329 2323 2355] (redman)
7/21/99 (new feature) Applied patch from Rolf Schroedter to add
-pollinterval option to fconfigure for Windows serial ports. Allows
the maxblocktime to be modified to control how often serial ports are
checked for fileevents. Also added documentation for \\.\comX
notation for opening serial ports on Windows. (redman)
7/21/99 (bug fix) Changed APIs in stub tables to use "unsigned long"
instead of the platform-specific "size_t", primarily after SunOS 4
users could no longer compile. (redman)
7/22/99 (bug fix) Fixed crashing during "array set a(b) {}".
[Bug: 2427] (redman)
7/22/99 (bug fix) The install-sh script must be given execute
permissions prior to running. [Bug: 2413] (redman)
7/22/99 (bug fix) Applied patch from Ulrich Ring to remove ANSI-style
prototypes in the code. [Bug: 2391] (redman)
7/22/99 (bug fix) Added #if blocks around #includes of sys/*.h header
files, to allow an extension author on Windows to use the MetroWerks
compiler. [Bug: 2385] (redman)
7/22/99 (bug fix) Fixed running the safe.test test suite, one change
to the Windows Makefile.in to fix paths and another in safe.test to
check for the tcl_platform(threaded) variable properly. (redman)
7/22/99 (bug fix) Fixed hanging in new Win32 socket driver with
threads enabled. (redman)
7/26/99 (bug fix) Fixed terminating of helper threads by holding any
mutexes from the primary thread while waiting for the helper thread to
terminate. Fixes dual-CPU WinNT hangs, only one rare sporadic hang
that still exists with dual-CPU WinNT. Also fixed test cases so that
they would not depend as much on timing for dual-CPU WinNT. (redman)
7/27/99 (bug fix) Some test suite cleanup. (jenn)
7/29/99 (bug fix) Applied patch to fix typo in .SH NAME line in
doc/Encoding.n [Bug: 2451]. Applied patch to avoid linking pack.n to
pack-old.n [Bug: 2469]. Patches from Don Porter. (redman)
7/29/99 (bug fix) Allow tcl to open CON and NUL, even for redirection
of std channels. [Bug: 2393 2392 2209 2458] (redman)
7/30/99 (bug fix) Applied fixed Trf patch from Andreas Kupries.
[Bug: 2386] (hobbs)
7/30/99 (bug fix) Fixed bug in info complete. [Bug: 2383 2466] (hobbs)
7/30/99 (bug fix) Applied patch to fix threading on Irix 6.5, patch
provided by James Dennett. [Bug: 2450] (redman)
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.
7/30/99 (bug fix) Added functions to stub table, patch provided by Jan
Nijtmans. [Bug: 2445] (hobbs)
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. (redman)
--------------- Released 8.2b2, August 5, 1999 ----------------------
8/4/99 (bug fix) Applied patches supplied by Henry Spencer to greatly
enhance performance of certain classes of regular expressions.
[Bug: 2440 2447] (stanton)
8/5/99 (doc change) Made it clear that tcl_pkgPath was not set for
Windows. [Bug: 2455] (hobbs)
8/5/99 (bug fix) Fixed reference to bytes that might not be null
terminated in tclLiteral.c. [Bug: 2496] (hobbs)
8/5/99 (bug fix) Fixed typo in http.tcl. [Bug: 2502] (hobbs)
8/9/99 (bug fix) Fixed test suite to handle larger integers
(64bit). Patch from Don Porter. (hobbs)

8/9/99 (bug fix) Fixed path handling in auto_execok [Bug: 1276] (hobbs)
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)
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)
8/9/99 (bug fix) Traces were not firing on "info exists", which used to
happen in Tcl 7.6 and earlier. An "info exists" now fires a read trace,
if defined. This makes it possible to fully implement variables that
are defined via traces. (welch)
8/10/99 (bug fix) Fixed Brent's changes so that they work on
Windows. (redman)
--------------- Released 8.2b3, August 11, 1999 ----------------------
8/12/99 (Mac) Rearrange projects in tclMacProjects.sea.hqx so that the
build directory is separate from the sources. (Jim Ingham)
8/12/99 (bug fix) Fixed bug in Tcl_EvalEx where the termOffset was not
being updated in cases where the evaluation returned a non TCL_OK
error code. [Bug: 2535] (stanton)
--------------- Released 8.2.0, August 17, 1999 ----------------------
9/21/99 (config fixes) fixed several AIX configuration issues. gcc and
threading may still cause problems on AIX. (hobbs)
9/21/99 (bug fix) fixed expr double-eval problem. [Bug: 732] (hobbs)
9/21/99 (bug fix) fixed static buffer overflow problem. [Bug: 2483] (hobbs)
9/21/99 (bug fix) fixed end-int linsert interpretation. [Bug: 2693] (hobbs)
9/21/99 (bug fix) fixed bug when setting array in non-existent
namespace. [Bug: 2613] (hobbs)
--- Released 8.2.1, October 04, 1999 --- See ChangeLog for details ---
10/30/99 (feature enhancement) new regexp engine from Henry Spencer
was patched in - should greatly reduce stack space usage. (spencer)
10/30/99 (bug fix) fixed Purify reported memory leaks in findexecutable
test command, TclpCreateProcess on Unix, in handling of C environ array,
and in testthread code. No more known (reported) mem leaks for Tcl
built using gcc on Solaris 2.5.1. Also none reported for Tcl on NT
(using Purify 6.0). (hobbs)
10/30/99 (bug fix) fixed improper bytecode handling of
'eval {set array($unknownvar) 5}' (also for incr) (hobbs)
10/30/99 (bug fix) fixed event/io threading problems by making
triggerPipe non-blocking (nick kisserbeth)
10/30/99 (bug fix) fixed Tcl_AppendStringsToObjVA and Tcl_AppendResultVA
to only iterates once over the va_list (avoiding non-portable memcpy).
(joe english, hobbs)
10/30/99 (bug fix) removed savedChar trick in tclCompile.c that appeared
to be causing a segv when the literal table was released.
[Bug: 2459, 2515] (David Whitehouse)
10/30/99 (bug fix) fixed [string index] to return ByteArrayObj
when indexing into one (test case string-5.16) [Bug: 2871] (hobbs)
10/30/99 (bug fix) fixes for mac UTF filename handling (ingham)
--- Released 8.2.2, November 04, 1999 --- See ChangeLog for details ---
11/19/99 (feature enhancement) bug fixes for http package as well as
patch required by TLS (SSL) extension that adds http::(un)register
and -type to http::geturl. Up'd http pkg version to 2.2.
11/19/99 (bug fix) removed extra decr of numLevels in Tcl_EvalObjEx
that could cause seg fault (mjansen@wendt.de)
11/19/99 (bug fixes) numerous minor big fixes, including correcting the
installation of the koi8-r encoding and tcltest1.0 on Windows.
11/30/99 (bug fix) fixes scan where %[..] didn't match anything
11/30/99 (bug fix) fixed setting of isNonBlocking flag in PipeBlockModeProc
so you can now close a non-blocking channel without waiting.
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.
12/07/99 (bug fix) fixes for 'expr + {[incr]}' and 'expr + {[error]}'
cases (different causes).
--- Released 8.2.3, December 16, 1999 --- See ChangeLog for details ---

--- Released 8.4.6, March 1, 2004 --- See ChangeLog for details ---
Changes to 8.5a1 include all changes to the 8.4 line through 8.4.6,
plus the following, which focuses on the high-level feature changes
in this changeset (new minor version) rather than bug fixes:
* refactored IO code to split FS path code into generic/tclPathObj.c
and generic/tclFileSystem.h
* refactored trace code into generic/tclTrace.c
* configure scripts now require autoconf 2.57 for regeneration
* updated runtime library scripts to use newer Tcl code features
(like replacing regsub with string map)
* improve robustness of tcltest test suite across environments
* changed the bytecode evaluation-stack addressing mode, from array-style
to pointer-style; the catch stack and evaluation stack are now
contiguous in memory
* switch command is now byte-compiled
* enhanced checking in 'file' command for Windows NT file permissions
* [TIP #57] new 'lassign' command (adopted from TclX)
* [TIP #75] switch -regexp now provides submatch info
* [TIP #90] extended 'catch' and 'return' to enable creation of procs
that are a true replacement for 'return'
* [TIP #100] new 'unload' command (can unload DLLs loaded via 'load',
requires the extension writer to support it)
* [TIP #111] new 'dict' command. Several commands have been updated
to handle the list form of dicts implicitly at the C level where
only lists were previously accepted
* [TIP #112] 'namespace ensemble' command addition allows for ensembles
that build on the namespace abstraction
* [TIP #118] file attributes -readonly option for unices that support
chflags(), support Mac Classic attribute options on OS X, add
-rsrclength for OS X, enhance file copy on OS X to copy finder
attributes and resource forks transparently
* [TIP #120] enable dde in safe interpreters
* [TIP #130] enable unique dde server names on Windows
* [TIP #135] change dde servername -exact option to -force
=> dde 1.3
* [TIP #121] new Tcl_SetExitProc C API to control application shutdown
* [TIP #123] expr ** exponentiation operator
* [TIP #124] 'clock clicks -milliseconds' now returns a wide integer and a
new 'clock clicks -microseconds' returns a wide integer, representing
the number of microseconds, both since the Posix epoch
* [TIP #127] added 'lsearch -index' option
* [TIP #136] added 'lrepeat' command
* [TIP #137/151] Add -encoding option to 'source' command and main tclsh
executable.
*** POTENTIAL INCOMPATIBILITY ***
For Tcl embedders that build on Tcl_Main() and make use of Tcl_Main's
former ability to pass a leading "-encoding" option to interactive shell
operations, this will now be consumed by Tcl.
* [TIP #138] New TCL_HASH_KEY_SYSTEM_HASH option for Tcl hash tables
* [TIP #139] documented portions of Tcl's namespace C APIs
* [TIP #148] correct [list]-quoting of the '#' character
*** POTENTIAL INCOMPATIBILITY ***
For scripts that assume a particular (buggy) string rep for lists.
* [TIP #156] add "root locale" to msgcat
=> msgcat 1.4
* [TIP #157] leading {expand} syntax on words to cause argument expansion.
This is a safer/cleaner alternative to the use of 'eval'.
