| | | | | | | | | | | | I also find the revised "createPart2" values in *Lookup* calls appealing, but I'm too fearful of breaking things without understanding the implications. This approach just focuses on fixing the things I broke, without trying to "fix" things long "broken" in multiple years of releases.

Also apply filters so that public routines only pass documented flag values down to lower level routines. * generic/tclVar.c (CallVarTraces): The setting of the TCL_INTERP_DESTROYED flag is now done entirely within the CallVarTraces routine, the only place it can be done right.

(SC_ENABLE_LANGINFO, SC_TIME_HANDLER): add/fix caching, fix obsolete autoconf macros. Sync with tk/unix/tcl.m4, sync whitespace with HEAD. * unix/configure.in: fix obsolete autoconf macros, sync gratuitous formatting/ordering differences with tk/unix/configure.in. * unix/Makefile.in: add CFLAGS to tclsh/tcltest link to make executable linking the same as during configure (needed to avoid loosing any linker relevant flags in CFLAGS, in particular flags that can't be in LDFLAGS). Avoid concurrent linking of tclsh and compiling of tclTestInit.o or xtTestInit.o during parallel make. (checkstubs, checkdoc, checkexports): dependency and Darwin fixes * unix/tclLoadDyld.c (TclpDlopen): use NSADDIMAGE_OPTION_WITH_SEARCHING on second NSAddImage only. [Bug 1204237] (TclGuessPackageName): should not be MODULE_SCOPE. (TclpLoadMemory): ppc64 and endian (i386) fixes, add support for loading universal (fat) bundles from memory. * unix/tclUnixPort.h: * unix/tclUnixFCmd.c: add support for new Tiger copyfile() API to enable copying of xattrs & ACLs by [file copy]. * generic/tcl.h: add Darwin specifc configure overrides for TCL_WIDE defines to support fat compiles of ppc and ppc64 at the same time, (replaces Darwin CVS fix by emoy, rdar://3693001). add/correct location of version numbers in macosx files. * generic/tclInt.h: clarify fat compile comment. * unix/tclUnixPort.h: add Darwin specifc configure overrides to support fat compiles, where configure runs only once for multiple architectures (replaces Darwin CVS fix by emoy, rdar://3693001). * macosx/tclMacOSXBundle.c: * macosx/tclMacOSXNotify.c: * unix/tclUnixNotfy.c: * unix/tclUnixPort.h: fix #include order to support compile time override of HAVE_COREFOUNDATION in tclUnixPort.h when building for ppc64 * macosx/Tcl.pbproj/default.pbxuser (new file): * macosx/Tcl.pbproj/jingham.pbxuser: * macosx/Tcl.pbproj/project.pbxproj: sync with HEAD. * macosx/README: clarification/cleanup, sync with HEAD, document universal (fat) builds via CFLAGS (i.e. all of ppc ppc64 i386 at once). * macosx/Makefile: add support for reusing configure cache, build target fixes, remove GENERIC_FLAGS override now handled by tcl.m4. * generic/tclIOUtil.c: * generic/tclRegexp.c: * generic/tclVar.c: declare globals used only in own file as static (sync with HEAD). * generic/rege_dfa.c (getvacant): * generic/regexec.c (cfind): * generic/tclCompExpr.c (CompileSubExpr): * unix/tclUnixChan.c (TclUnixWaitForFile): initialise variables to silence gcc 4 warnings. * generic/regguts.h: only #define NDEBUG if not already #defined. * macosx/tclMacOSXNotify.c: sync whitespace & comments with HEAD * unix/configure: regen.

The consequences of [Bug 736729] should be the same as in tcl8.3 and previous versions. The use of tclNsVarNameType objs is still disabled, pending a decision by the release manager.

Also made the Tcl_Value struct have a wideValue field on all platforms. This is a ***POTENTIAL INCOMPATIBILITY*** for TCL_WIDE_INT_IS_LONG platforms because that struct changes size. This is the same TIP 72 incompatibility that was seen on other platforms at the 8.4.0 release, when this change should have happened as well. [Bug 713562] * generic/tclInt.h: New internal macros TclGetWide() and TclGetLongFromWide() to deal with both forms of the "wideInt" Tcl_ObjType, so that conditional TCL_WIDE_INT_IS_LONG code is confined to the header file. * generic/tclCmdAH.c: Replaced most coding that was conditional * generic/tclCmdIL.c: on TCL_WIDE_INT_IS_LONG with code that * generic/tclExecute.c: works across platforms, sometimes using * generic/tclTest.c: the new macros above to do it. * generic/tclUtil.c: * generic/tclVar.c:
