| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * All of the changes below belong to TIP #10 [Tcl I/O Enhancement: Thread-Aware Channels]. See also [Patch #403358] at SF. * generic/tclIO.h (struct ChannelState, line 236f): Extended the structure with a new field of type 'Tcl_ThreadId' to hold the id of the thread currently managing all channels with this state. Note: This structure is shared by all channels in a stack of transformations. * generic/tclIO.c (Tcl_CreateChannel, lines 1058-1065): Modified to store the Id of the current thread in the 'ChannelState' of the new channel. * generic/tclIO.c (Tcl_SpliceChannel, lines 2265-2270): Modified in the same manner as 'Tcl_CreateChannel' as the channel will be managed by the current thread afterward. * generic/tclIO.c (Tcl_GetChannelThread, lines 1478-1503): * generic/tcl.decls (Tcl_GetChannelThread, lines 1504-1506): New API function to retrieve the Id of the managing thread from a channel. Implementation and declaration. * generic/tclTest.c (TestChannelCmd, lines 4520-4532): Added subcommand 'mthread' to query a channel about its managing thread.

| | | | | | | | | | * generic/tclIO.c (CopyData): Moved code that updates the count of how many bytes are left to copy. Corrects bug that when writing occurs in the background, the copy loop could be escaped without updating the count, causing CopyData() to try to copy more bytes than the toRead value originally passed to TclCopyChannel(), leading to hangs and misreporting of number of bytes copied. [Bug 118203, Patch 103432]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Overall changes: (1) Implementation of joinable threads for all platforms. (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.
