(2) Additional API's for channels. Required to allow the thread extension to move channels between threads. * generic/tcl.decls (lines 1360f): Added Tcl_JoinThread, Tcl_IsChannelShared, Tcl_IsChannelRegistered, Tcl_CutChannel, Tcl_SpliceChannel, Tcl_IsChannelExisting and Tcl_ClearChannelHandlers (slots 394 to 400). * generic/tclIO.c: Implemented Tcl_IsChannelRegistered, Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel, Tcl_IsChannelExisting and Tcl_ClearChannelHandlers. Tcl_CutChannel uses code from CloseChannel. Replaced this code by a call to Tcl_CutChannel. Replaced several code fragments adding channels to the channel list with calls to Tcl_SpliceChannel. Removed now unused variables from CloseChannel and Tcl_UnstackChannel. Tcl_ClearChannelHandlers uses code from Tcl_Close. Replaced this code by a call to Tcl_ClearChannelHandlers. Removed now unused variables from Tcl_Close. Added the subcommands 'cut', 'forgetch', 'splice' and 'isshared' to the test code (TclTestChannelCmd). * unix/tclUnixThread.c: Implemented Tcl_JoinThread using the pthread-functionality. * win/tclWinThrd.c: Fixed several small typos in comments. Implemented Tcl_JoinThread using a platform independent emulation layer (see generic/tclThreadJoin.c below). Added 'joinLock' to serialize Tcl_CreateThread and TclpExitThread to prevent a race for joinable threads. * mac/tclMacThrd.c: Implemented Tcl_JoinThread using a platform independent emulation layer (see generic/tclThreadJoin.c below). Due to the cooperative nature of threading on this platform the race mentioned above is not present. * generic/tclThreadJoin.c: New file. Contains a platform independent emulation layer helping in the implementation of joinable threads for the win and mac platforms. * generic/tclInt.h: Added declarations for TclJoinThread, TclRememberJoinableThread and TclSignalExitThread. These procedures define the API of the emulation layer for joinable threads (see generic/tclThreadJoin.c above). * win/Makefile.in: * win/makefile.vc: Added generic/tclTheadJoin.o to the rules. * mac/: I don't know to which file generic/tclTheadJoin.o has to be added to so that it compiles. Sorry. * unix/tclUnixChan.c: #ifdef'd the thread-local list of file channels as it prevents us from transfering channels. To restore this we may need an extended interface to drivers in the future. Target: 9.0. Found while testing the new transfer of channels. The information in this list for a channel was left behind and then crashed the system during finalization. * generic/tclThreadTest.c: Added -joinable flag to 'testthread create'. Added subcommand 'testthread join'. * doc/CrtChannel.3: Added documentation for Tcl_IsChannelRegistered, Tcl_IsChannelShared, Tcl_CutChannel, Tcl_SpliceChannel, Tcl_IsChannelExisting and Tcl_ClearChannelHandlers. * doc/Thread.3: Added documentation for Tcl_JoinThread. * tests/thread.test: Added tests for joining of threads.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Overall change: Definition of a public API for the creation of new threads. * generic/tclInt.h (line 1802f): Removed the definition of 'TclpThreadCreate'. (line 793f) Removed the definition of 'Tcl_ThreadCreateProc'. * generic/tcl.h (line 388f): Readded the definition of 'Tcl_ThreadCreateProc'. Added Win32 stuff send in by David Graveraux <davygrvy@bigfoot.com> to that too (__stdcall, ...). Added macros for the default stacksize and allowed flags. * generic/tcl.decls (line 1356f): Added definition of 'Tcl_CreateThread', slot 393 of the stub table. Two new arguments in the public API, for stacksize and flags. * win/tclWinThrd.c: * mac/tclMacThrd.c: Renamed TclpThreadCreate to Tcl_CreateThread, added handling of the stacksize. Flags are currently ignored. * unix/tclUnixThrd.c: See above, but handles joinable flag. Ignores the specified stacksize if the macro HAVE_PTHREAD_ATTR_SETSTACKSIZE is not defined. * generic/tclThreadTest.c (line 363): See below. * unix/tclUnixNotfy.c (line 210): Adapted to the changes above. Uses default stacksize and no flags now. * unic/tcl.m4 (line 382f): Added a check for 'pthread_attr_setstacksize' to detect platforms not implementing this feature of pthreads. If it is implemented, configure will define the macro HAVE_PTHREAD_ATTR_SETSTACKSIZE (See unix/tclUnixThrd.c too). * doc/Thread.3: Added Tcl_CreateThread and its arguments to the list of described functions. Removed stuff about not providing a public C-API for thread-creation.

[Bug: 4199]. * generic/tclInt.h: Removed definitions of TclFinalizeMutex and TclFinalizeCondition. * generic/tcl.decls: Added declarations of Tcl_MutexFinalize and Tcl_ConditionFinalize. * generic/tclThread.c: Renamed TclFinalizeMutex to Tcl_MutexFinalize. Renamed TclFinalizeCondition to Tcl_ConditionFinalize. * generic/tclNotify.c: Changed usage of TclFinalizeMutex to Tcl_MutexFinalize. * unix/tclUnixNotfy.c: * generic/tclThreadTest.c: Changed usages of TclFinalizeCondition to Tcl_ConditionFinalize. * generic/tcl.h: Added empty macros for Tcl_MutexFinalize and Tcl_ConditionFinalize, to be used when the core is compiled without threads. * doc/Thread.3: Added description the new API's.

| | | | | | | | | * generic/tcl.decls: moved Tcl_ProcObjCmd to stubs table [Bug: 3827] and removed 'register' from stub definition of Tcl_AppendUnicodeToObj [Bug: 4038] * generic/tclFileName.c: improved guessing of path separator for the Mac. (Darley)

The optimization was removed, which means that: expr 1 + {[string length abc]} will be not be compiled inline as before, but this should be written: expr {1 + [string length abc]} which will be compiled inline for speed. This prevents expr 1 + {[mindless error]} from seg faulting, and only affects optimizations for degenerate cases [Bug: 3737]

* * generic/tclUnicodeObj.c: Lots of cleanup and simplification.stanton1999-06-101-1/+6
| | | | | | | | | | | | | | | | | | | | | | | Fixed several memory bugs. Added TclAppendUnicodeToObj. * generic/tclInt.h: Added declarations for various Unicode string functions. * generic/tclRegexp.c: * generic/tclCmdMZ.c: Changed to use new Unicode string interfaces for better performance. * generic/tclRegexp.h: * generic/tclRegexp.c: * generic/tcl.h: * generic/tcl.decls: Added Tcl_RegExpMatchObj and Tcl_RegExpGetInfo calls to access lower level regexp API. These features are needed by Expect. This is a preliminary implementation pending final review and cleanup. * generic/tclCmdMZ.c: * tests/string.test: Fixed bug where string map failed on null strings.

Objects with other internal reps are converted to have the new unicode internal rep. * unix/Makefile.in: * win/Makefile.in: * win/Makefile.vc: * tests/unicode.test: * generic/tclInt.h: * generic/tclObj.c: * generic/tclUnicodeObj.c: added a new object type to store the unicode representation of a string. * generic/tclTestObj.c: added the objtype option to the testobj command. This option returns the name of the type of internal rep an object has.

| | | | | | | | | | | | * generic/tclInt.h: * generic/tclBasic.c: * generic/tclRegexp.h: * generic/tclRegexp.c: 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. [Bug: 1063]
* * generic/tclInt.h:stanton1999-04-221-3/+10
| | | | | | | | | | | * generic/tclInt.decls: * generic/tclCompile.c: Added TclSetByteCodeFromAny that takes a hook procedure to invoke after compilation but before the byte codes are emitted. This makes it possible to do postprocessing on the compiled byte codes before the ByteCode is generated. * generic/tclLiteral.c: Added TclHideLiteral and TclAddLiteralObj to make it possible to create local unshared literal objects.

| | | | | | | | * generic/tclNamesp.c (TclGetNamespaceForQualName): Restored signature so that TclGetNamespaceForQualName returns an int, even though it is always TCL_OK. This is needed for forwards compatibility of tbcload. This should be removed at some point, when we are willing to break forward compatibility.
