* * generic/tclIO.c (UpdateInterest): When dropping interest inandreas_kupries2003-04-111-1/+44
| | | | | | | TCL_READABLE now dropping interest in TCL_EXCEPTION too. This fixes a bug where Expect detects eof on a file prematurely on solaris 2.6 and higher. A much more complete explanation is in the code itself (40 lines of comments for a one-line change :)
* * generic/tclIO.c (Tcl_Seek, Tcl_OutputBuffered):mdejong2003-03-061-3/+13
| | | | | | | | | | | | | | | | | If there is data buffered in the statePtr->curOutPtr member then set the BUFFER_READY flag in Tcl_Seek. This is needed so that the next call to FlushChannel will write any buffered bytes before doing the seek. The existing code would set the BUFFER_READY flag inside the Tcl_OutputBuffered function. This was a programming error made when Tcl_OutputBuffered was originally created in CVS revision 1.35. The setting of the BUFFER_READY flag should not have been included in the Tcl_OutputBuffered function. * generic/tclTest.c (TestChannelCmd): Use the Tcl_InputBuffered and Tcl_OutputBuffered util methods to query the amount of buffered input and output.
* * generic/tclIO.c (Tcl_Flush): Compare themdejong2003-03-061-2/+3
| | | | | | | | | | nextAdded member of the ChannelBuffer to the nextRemoved member to determine if any output has been buffered. The previous check against the value 0 seems to have just been a coding error. See other methods like Tcl_OutputBuffered for examples where nextAdded is compared to nextRemoved to find the number of bytes buffered.
* * generic/tclIO.c (Tcl_GetsObj): Check thatmdejong2003-03-061-2/+2
| | | | | | | | | | the eol pointer has not gone past the end of the string when in auto translation mode and the INPUT_SAW_CR flag is set. The previous code worked because the end of string value \0 was being compared to \n, this patch just skips that pointless check.
* * generic/tclIO.c (WriteBytes, WriteChars,mdejong2003-03-061-4/+15
| | | | | | | | | Tcl_GetsObj, ReadBytes): Rework calls to TranslateOutputEOL to make it clear that a boolean value is being returned. Add some comments in an effort to make the code more clear. This patch makes no functional changes.
* * generic/tclIO.c (Tcl_SetChannelOption):mdejong2003-03-061-5/+3
| | | | | | | | | | | | | Invoke the Tcl_SetChannelBufferSize method as a result of changing the -buffersize option to fconfigure. The previous implementation used some inlined code that reset the buffer size to the default size instead of ignoring the request as implemented in Tcl_SetChannelBufferSize. * tests/io.test: Update test case so that it actually checks the implementation of Tcl_SetChannelBufferSize.

* * generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel):mdejong2003-01-261-1/+5
| | | | | | | | | | | | | | | | Invoke TclpCutFileChannel and TclpSpliceFileChannel. * generic/tclInt.h: Declare TclpCutFileChannel and TclpSpliceFileChannel. * unix/tclUnixChan.c (FileCloseProc, TclpOpenFileChannel, Tcl_MakeFileChannel, TclpCutFileChannel, TclpSpliceFileChannel): Implement thread load data cut and splice for file channels. This avoids an invalid memory ref when compiled with -DDEPRECATED. * win/tclWinChan.c (FileCloseProc, TclpCutFileChannel, TclpSpliceFileChannel): Implement thread load data cut and splice for file channels. This avoids an invalid memory ref that was showing up in the thread extension.

* * tests/io.test:andreas_kupries2002-07-301-2/+16
| | | | | | | | | * generic/tclIO.c (WriteChars): Added flag to break out of loop if nothing of the input is consumed at all, to prevent infinite looping of called with a non-UTF-8 string. Fixes Bug 584603 (partially). Added new test "io-60.1". Might need additional changes to Tcl_Main so that unprintable results are printed as binary data.

| | | | | | | * generic/tclIO.c (FilterInputBytes): reset the TCL_ENCODING_START flags in the ChannelState when using 'gets'. [Bug #523988] Also reduced the value of ENCODING_LINESIZE from 30 to 20 as this seems to improve the performance of 'gets' according to tclbench.
* TIP#72 implementation. See ChangeLog for details.dkf2002-02-151-34/+69
| | | | | This version builds clean on Solaris/SPARC, with GCC and CC, both with and without threads and both in 32-bit and 64-bit mode.

[Bug 496733] * generic/tclIO.c (Tcl_GetChannelOption, Tcl_SetChannelOption): Instead of returning nothing for the -translation option on a server socket, always return "auto". Return the empty string enclosed in quotes for the -eofchar option on a server socket. Fixup -eofchar usage message so that it matches the implementation. * tests/io.test: Add -eofchar tests and -translation tests to ensure options are read only on server sockets. * tests/socket.test: Update tests to account for -eofchar and -translation option changes.

| | | | | | | | | | | generic/tclIOUtil.c, generic/tclPipe.c, generic/tclResult.c, generic/tclUtil.c, generic/tclVar.c and mac/tclMacResource.c according to TIP 27. Tcl_TranslateFileName rewritten as wrapper around VFS-aware version. Updated callers. ***POTENTIAL INCOMPATIBILITY*** Includes source incompatibilities: argv arguments of Tcl_Concat, Tcl_JoinPath, Tcl_OpenCommandChannel, Tcl_Merge; argvPtr arguments of Tcl_SplitList and Tcl_SplitPath.
* * generic/tclIO.c (WriteChars): Fix for SF #506297, reported byandreas_kupries2002-01-211-1/+19
| | | | | | | | | | | | | | Martin Forssen <ruric@users.sourceforge.net>. The encoding chosen in the script exposing the bug writes out three intro characters when TCL_ENCODING_START is set, but does not consume any input as TCL_ENCODING_END is cleared. As some output was generated the enclosing loop calls UtfToExternal again, again with START set. Three more characters in the out and still no use of input ... To break this infinite loop we remove TCL_ENCODING_START from the set of flags after the first call (no condition is required, the later calls remove an unset flag, which is a no-op). This causes the subsequent calls to UtfToExternal to consume and convert the actual input.
* * More TIP 27 updates in tclIOUtil.c and tclIndexObj.c that weredgp2002-01-171-2/+2

| | | | | | | | | | | | | | | | | | | | | | | more than was in the buffers and then blocked in the OS call as its pty channel driver provides no blockmodeproc through which the OS could be notified of blocking-behaviour. Because of this the general I/O core has to take more care than usual to preserve the semantics of non-blocking channels. * generic/tclIO.c (Tcl_ReadRaw): Do not read from the driver if the channel is non-blocking and the fileevent causing the read was generated by a timer. We do not know if there is data available from the OS. Instead of going to the OS for more and potentially blocking we simply signal EWOULDBLOCK to the higher levels to cause the system to wait for true fileevents. (GetInput): Same as before. (ChannelTimerProc): Added set and clear of CHANNEL_TIMER_FEV. * generic/tclIO.h (CHANNEL_TIMER_FEV): New flag for channels. Is set if a fileevent was generated by a timer, the channel is not blocking and the driver did not provide a blockmodeproc. In that case the I/O core has to be especially careful about going to the driver for more data.

| | | | | | | * generic/tclIO.c: Aftermath to [SF #427196]. Squash empty buffers if they are smaller than the requested buffersize, to prevent reusage of old buffers and to honor changes in the requested buffersize made by the user.
* 2001-07-17 Andreas Kupries <andreas_kupries@users.sourceforge.net>andreas_kupries2001-07-171-2/+16
| | | | | | | | | | * generic/tclIO.c (GetInput): Fixed [SF #427196]. Memory was overwritten because a buffer was used after a change of the requested buffersize together with that requested buffersize and not its actual size, which was smaller. Note that the continous reuse of the smaller buffer negatively impacts performance. The system never allocates a buffer with the newly requested bigger buffersize.

The public functions now use the new internal ones. The new functions are 'DoReadChars' and 'DoWriteChars'. Extended 'CopyData' to use the new functions 'DoXChars' when required by the encodings on the input and output channels [Bug #209210].

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.

| | | | | | | | | | * 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.

(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.
