| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | notifier thread lazily upon first call to Tcl_WaitForEvent() rather than in Tcl_InitNotifier(). Allows calling exeve() in processes where the event loop has not yet been run (Darwin's execve() fails in processes with more than one thread), in particular allows embedders to call fork() followed by execve(), previously the pthread_atfork() child handler's call to Tcl_InitNotifier() would immediately recreate the notifier thread in the child after a fork. * macosx/tclMacOSXFCmd.c (TclMacOSXCopyFileAttributes): add support * macosx/tclMacOSXNotify.c (Tcl_InitNotifier): for weakly * unix/tclUnixInit.c (Tcl_GetEncodingNameFromEnvironment): importing symbols not available on OSX 10.2 or 10.3, enables binaires built on later OSX versions to run on earlier ones. * macosx/Tcl.xcodeproj/project.pbxproj: enable weak-linking; turn on extra warnings. * macosx/README: document how to enable weak-linking; cleanup. * unix/tclUnixPort.h: add support for weak-linking; conditionalize AvailabilityMacros.h inclusion; only disable realpath on 10.2 or earlier when threads are enabled. * unix/tclLoadDyld.c (TclpLoadMemoryGetBuffer): change runtime Darwin * unix/tclUnixInit.c (TclpInitPlatform): release check to use global initialized once. * unix/tclUnixFCmd.c (DoRenameFile, TclpObjNormalizePath): add runtime Darwin release check to determine if realpath is threadsafe. * unix/configure.in: add check on Darwin for compiler support of weak * unix/tcl.m4: import and for AvailabilityMacros.h header; move Darwin specific checks & defines that are only relevant to the tcl build out of tcl.m4; restrict framework option to Darwin; cleanup quoting and help messages. * unix/configure: autoconf-2.59 * unix/tclConfig.h.in: autoheader-2.59 * unix/tclLoadDyld.c (TclpLoadMemory): fix signed-with-unsigned comparison and other warnings from gcc4 -Wextra.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that builds a parse tree instead of operating with deep recursion. This corrects reports of stack-blowing crashes parsing long expressions [Bug 906201] and replaces a fundamentally O(N^2) algorithm with an O(N) one [RFE 903765]. The new parser is better able to generate error messages that clearly report both the nature and context of the syntax error [Bugs 1029267, 1381715]. For now, the code for the old parser is still present and can be activated with a "#define OLD_EXPR_PARSER 1". This is for the sake of a clean implementation patch, and for ease of benchmarking. The new parser is non-recursive, so much lighter in stack consumption, but it does use more heap, so there may be cases where parsing of long expressions that succeeded with the old parser will lead to out of memory panics with the new one. There are still more improvements possible on that point, though significant progress may require changes to the Tcl_Token specifications documented for the public Tcl_Parse*() routines. ***POTENTIAL INCOMPATIBILITY*** for any callers that rely on the exact (usually terrible) error messages generated by the old parser. This includes a large number of tests in the test suite. * generic/tclInt.h: Replaced TclParseWhiteSpace() with * generic/tclParse.c: TclParseAllWhiteSpace() which is what * generic/tclParseExpr.c: all the callers really needed. Breaking whitespace runs at newlines is useful only to the command parsing function, and it can call the file scoped routine ParseWhiteSpace() to do that. * tests/expr-old.test: Removed knownBug constraints that masked * tests/expr.test: failures due to revised error messages. * tests/parseExpr.test:

| | | | | | | | | | | | | * unix/tcl.m4 (Darwin): recreates CoreFoundation state and notifier thread in the child after a fork(). Note that pthread_atfork() is available starting with Tiger only. Because vfork() is used by the core on Darwin, [exec]/[open] are not affected by this fix, only extensions or embedders that call fork() directly (such as TclX). However, this only makes fork() safe from corefoundation tcl with --disable-threads; as on all platforms, forked children may deadlock in threaded tcl due to the potential for stale locked mutexes in the child.
