Tcl Source Code

2012-07-16  Jan Nijtmans  <[email protected]>

	* library/reg/pkgIndex.tcl:  Make registry 1.3 package dynamically
	loadable in Tcl 8.4.20.

2012-07-11  Jan Nijtmans  <[email protected]>

	* win/tclWinReg.c: [Bug #3362446]: registry keys command fails
	with 8.5/8.6. Follow Microsofts example better in order to prevent
	problems when using HKEY_PERFORMANCE_DATA.

2012-07-10  Jan Nijtmans  <[email protected]>

	* unix/tclUnixNotfy.c: [Bug 3541646] Don't panic on triggerPipe overrun

2012-07-10  Donal K. Fellows  <[email protected]>

	* win/tclWinSock.c (InitializeHostName): Corrected logic that
	extracted the name of the computer from the gethostname call so that
	it would use the name on success, not failure. Also ensured that the
	buffer size is exactly that recommended by Microsoft.

2012-07-08  Reinhard Max  <[email protected]>

	* library/http/http.tcl: Add fix and test for URLs that contain
	* tests/http.test: 	 literal IPv6 addresses. [Bug 3531209]

2012-07-05  Don Porter  <[email protected]>

	* unix/tclUnixPipe.c:	[Bug 1189293] Make "<<" binary safe.
	* win/tclWinPipe.c:

2012-07-03  Donal K. Fellows  <[email protected]>

	* generic/tclUtil.c (TclDStringAppendObj, TclDStringAppendDString):
	* generic/tclInt.h (TclDStringAppendLiteral, TclDStringClear):
	* generic/tclCompile.h (TclDStringAppendToken): Added wrappers to make
	common cases of appending to Tcl_DStrings simpler to write. Prompted
	by looking at [FRQ 1357401] (these are an _internal_ implementation of
	that FRQ).

2012-06-29  Jan Nijtmans  <[email protected]>

	* library/msgcat/msgcat.tcl:   Add tn, ro_MO and ru_MO to msgcat.

2012-06-29  Harald Oehlmann <[email protected]>

	* library/msgcat/msgcat.tcl:	[Bug 3536888] Locale guessing of msgcat
	* library/msgcat/pkgIndex.tcl:  fails on (some) Windows 7.  Bump to 1.4.5
	* unix/Makefile.in
	* win/Makefile.in

2012-06-29  Donal K. Fellows  <[email protected]>

	* doc/GetIndex.3: Reinforced the description of the requirement for
	the tables of names to index over to be static, following posting to
	tcl-core by Brian Griffin about a bug caused by Tktreectrl not obeying
	this rule correctly. This does not represent a functionality change,
	merely a clearer documentation of a long-standing constraint.

2012-06-26  Jan Nijtmans  <[email protected]>

	* unix/tcl.m4:       Let Cygwin shared build link with
	* unix/configure.in: zlib1.dll, not cygz.dll (two less
	* unix/configure:    dependencies on cygwin-specific dll's)
	* unix/Makefile.in:

2012-06-26  Reinhard Max  <[email protected]>

	* generic/tclIOSock.c: Use EAI_SYSTEM only if it exists.
	* unix/tclUnixSock.c:

2012-06-25  Don Porter  <[email protected]>

	* generic/tclFileSystem.h:	[Bug 3024359] Make sure that the
	* generic/tclIOUtil.c:	per-thread cache of the list of file systems
	* generic/tclPathObj.c:	currently registered is only updated at times
	when no active loops are traversing it.  Also reduce the amount of
	epoch storing and checking to where it can make a difference.

	* tools/uniParse.tcl:    [Bug 3444754]: string tolower \u01c5 is wrong
	* generic/tclUniData.c:
	* tests/utf.test:

2011-11-30  Jan Nijtmans  <[email protected]>

	* library/tcltest/tcltest.tcl: [Bug 967195]: Make tcltest work
	when tclsh is compiled without using the setargv() function on mingw.


2011-11-29  Jan Nijtmans  <[email protected]>

	* win/Makefile.in: don't install tommath_(super)?class.h
	* unix/Makefile.in: don't install directories like 8.2 and 8.3
	* generic/tclTomMath.h: [Bug 2991415]: move include tclInt.h from
	* generic/tclTomMathInt.h: tclTomMath.h to tclTomMathInt.h

--- Released 8.6b3, July 30, 2012 --- See ChangeLog for details ---

.AP Tcl_Obj *objPtr in/out
The string value of this object is used to search through \fItablePtr\fR.
The internal representation is modified to hold the index of the matching
table entry.
.AP "const char *const" *tablePtr in
An array of null-terminated strings.  The end of the array is marked
by a NULL string pointer.
Note that references to the \fItablePtr\fR may be retained in the
internal representation of \fIobjPtr\fR, so this should represent the
address of a statically-allocated array.
.AP "const void" *structTablePtr in
An array of arbitrary type, typically some \fBstruct\fR type.
The first member of the structure must be a null-terminated string.
The size of the structure is given by \fIoffset\fR.
Note that references to the \fIstructTablePtr\fR may be retained in the
internal representation of \fIobjPtr\fR, so this should represent the
address of a statically-allocated array of structures.
.AP int offset in
The offset to add to structTablePtr to get to the next entry.
The end of the array is marked by a NULL string pointer.
.AP "const char" *msg in
Null-terminated string describing what is being looked up, such as
\fBoption\fR.  This string is included in error messages.
.AP int flags in
OR-ed combination of bits providing additional information for
operation.  The only bit that is currently defined is \fBTCL_EXACT\fR.
.AP int *indexPtr out
The index of the string in \fItablePtr\fR that matches the value of
\fIobjPtr\fR is returned here.
.BE
.SH DESCRIPTION
.PP
These procedures provide an efficient way for looking up keywords,
switch names, option names, and similar things where the value of
an object must be one of a predefined set of values.
\fBTcl_GetIndexFromObj\fR compares \fIobjPtr\fR against each of
the strings in \fItablePtr\fR to find a match.  A match occurs if
\fIobjPtr\fR's string value is identical to one of the strings in
\fItablePtr\fR, or if it is a non-empty unique abbreviation
for exactly one of the strings in \fItablePtr\fR and the
\fBTCL_EXACT\fR flag was not specified; in either case
the index of the matching entry is stored at \fI*indexPtr\fR
and \fBTCL_OK\fR is returned.

to extract its parts.  The initial locale is then set by calling
\fB::msgcat::mclocale\fR with the argument 
.PP
.CS
language[_country][_modifier]
.CE
.PP
On Windows and Cygwin, if none of those environment variables is set,
msgcat will attempt to extract locale information from the registry.
From Windows Vista on, the RFC4747 locale name "lang-script-country-options"
is transformed to the locale as "lang_country_script" (Example:
sr-Latn-CS -> sr_cs_latin). For Windows XP, the language id is
transformed analoguously (Example: 0c1a -> sr_yu_cyrillic).
If all these attempts to discover an initial locale from the user's
environment fail, msgcat defaults to an initial locale of

.QW C .
.PP
When a locale is specified by the user, a
.QW "best match"
search is performed during string translation.  For example, if a user
specifies
en_GB_Funky, the locales
