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. + 2000-04-27 Eric Melski <ericm@scriptics.com> * doc/library.n: Added entries for auto_qualify and auto_import |
