* TIP#218 IMPLEMENTATIONandreas_kupries2005-01-271-19/+60
| | | | | | | | | | | | | | | | | | | | * generic/tclDecls.h: Regenerated from tcl.decls. * generic/tclStubInit.c: * doc/CrtChannel.3: Documentation of extended API, * generic/tcl.decls: extended testsuite, and * generic/tcl.h: implementation. Removal of old * generic/tclIO.c: driver-specific TclpCut/Splice * generic/tclInt.h: functions. Replaced with generic * tests/io.test: thread-action calls through the * unix/tclUnixChan.c: new hooks. Update of all builtin * unix/tclUnixPipe.c: channel drivers to version 4. * unix/tclUnixSock.c: Windows drivers extended to * win/tclWinChan.c: manage thread state in a thread * win/tclWinConsole.c: action handler. * win/tclWinPipe.c: * win/tclWinSerial.c: * win/tclWinSock.c:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | startup/initialization of the Tcl library, focused on the activities of Tcl_FindExecutable(). * generic/tclIO.c: Removed bogus claim in comment that encoding "iso8859-1" is "built-in" to Tcl. * generic/tclInt.h: Created a new struct ProcessGlobalValue, * generic/tclUtil.c: routines Tcl(Get|Set)ProcessGlobalValue, and function type TclInitProcessGlobalValueProc. Together, these take care of the housekeeping for "values" (things that can be held in a Tcl_Obj) that are global across a whole process. That is, they are shared among multiple threads, and epoch and mutex protection must govern the validity of cached copies maintained in each thread. * generic/tclNotify.c: Modified TclInitNotifier() to tolerate being called multiple times in the same thread. * generic/tclEvent.c: Dropped the unused argv0 argument to TclInitSubsystems(). Removed machinery to unsure only one TclInitNotifier() call per thread, now that that is safe. Converted Tcl(Get|Set)LibraryPath to use a ProcessGlobalValue, and moved them to tclEncoding.c. * generic/tclBasic.c: Updated caller. * generic/tclInt.h: TclpFindExecutable now returns void. * unix/tclUnixFile.c: * win/tclWinFile.c: * win/tclWinPipe.c: * generic/tclEncoding.c: Built new encoding search initialization on a foundation of ProcessGlobalValues, exposing new routines Tcl(Get|Set)EncodingSearchPath. A cache of a map from encoding name to directory pathname keeps track of where encodings are available for loading. Tcl_FindExecutable greatly simplified into just three function calls. The "library path" is now misnamed, as its only remaining purpose is as a foundation for the default encoding search path. * generic/tclInterp.c: Inlined the initScript that is evaluated by Tcl_Init(). Added verification after initScript evaluation that Tcl can find its installed *.enc files, and that it has initialized [encoding system] in agreement with what the environment expects. [tclInit] no longer driven by the value of $::tcl_libPath; it largely constructs its own search path now, rather than attempt to share one with the encoding system. * unix/tclUnixInit.c: TclpSetInitialEncodings factored so that a new * win/tclWinInit.c: routine TclpGetEncodingNameFromEnvironment can reveal that Tcl thinks the [encoding system] should be, even when an incomplete encoding search path, or a missing *.enc file won't allow that initialization to succeed. TclpInitLibraryPath reworked as an initializer of a ProcessGlobalValue. * unix/tclUnixTest.c: Update implementations of [testfindexecutable], [testgetdefenc], and [testsetdefenc]. * tests/unixInit.test: Corrected tests to operate properly even when a value of TCL_LIBRARY is required to find encodings. * generic/tclInt.decls: New internal stubs: TclGetEncodingSearchPath, TclSetEncodingSearchPath, TclpGetEncodingNameFromEnvironment. These are candidates for public exposure by future TIPs. * generic/tclIntDecls.h: make genstubs * generic/tclStubInit.c: * generic/tclTest.c: Updated [testencoding] to use * tests/encoding.test: Tcl(Get|Set)EncodingSearchPath. Updated tests.

Searched for example of this practice and replaced with safer alternatives, often using the Tcl_AppendResult() routine that dkf just rehabilitated.

* * generic/tclIO.h (CHANNEL_INCLOSE): New flag. Set inandreas_kupries2004-07-151-1/+45
| | | | | | | | | | | | | | | | | | | | | | * generic/tclIO.c (Tcl_UnregisterChannel): 'Tcl_Close' while the * generic/tclIO.c (Tcl_Close): close callbacks are run. Checked in 'Tcl_Close' and 'Tcl_Unregister' to prevent recursive call of 'close' in the close-callbacks. This is a possible error made by implementors of virtual filesystems based on 'tclvfs', thinking that they have to close the channel in the close handler for the filesystem. * generic/tclIO.c: * generic/tclIO.h: * Not reverting, but #ifdef'ing the changes from May 19, 2004 out of the core. This removes the ***POTENTIAL INCOMPATIBILITY*** for channel drivers it introduced. This has become possible due to Expect gaining a BlockModeProc and now handling blockingg and non-blocking modes correctly. Thus [SF Tcl Bug 943274] is still fixed if a recent enough version of Expect is used. * doc/CrtChannel.3: Added warning about usage of a channel without a BlockModeProc.
* * generic/tclIO.c (Tcl_SetChannelOption): Took out the rangedavygrvy2004-06-011-9/+1
| | | | | | | verification on -buffersize so original behavior for silently ignoring bad settings is returned. The only difference now is the behavior difference between atoi and Tcl_GetInt which gains the ability to error for 'not a number' and can understand hexidecimal.
* * generic/tclIO.c (Tcl_SetChannelOption): Invalid settingsdavygrvy2004-06-011-3/+14
| | | | | | for -buffersize weren't being reported as errors and were blindly ignored. Now reports conversion errors to an int and checks ranges for validity. atoi() swapped for Tcl_GetInt().
* * tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem asandreas_kupries2004-05-191-6/+89
| | | | | | | | | | | | | * tclIO.h: [SF Tcl Bug 462317], see ChangeLog entry 2001-09-26. The fix done at that time is incomplete. It is possible to get around it if the actual read operation is defered and not executed in the event handler itself. Instead of tracking if we are in an read caused by a synthesized fileevent we now track if the OS has delivered a true event = actual data and bypass the driver if a read finds that there is no actual data waiting. The flag is cleared by a short or full read.
* * generic/tclIO.c (Tcl_SetChannelOption): Fixed [SF Tcl Bugandreas_kupries2004-04-231-1/+10
| | | | | 930851]. When changing the eofchar we have to zap the related flags to prevent them from prematurely aborting the next read.

| | | | | | | | | | | | | | | | | | | | | | | * generic/tclInt.h: Reworked the Tcl header files into a clean * unix/tclUnixPort.h: hierarchy where tcl.h < tclPort.h < tclInt.h * win/tclWinInt.h: and every C source file should #include * win/tclWinPort.h: at most one of those files to satisfy its declaration needs. tclWinInt.h and tclWinPort.h also better organized so that tclWinPort.h includes the Windows implementation of cross-platform declarations, while tclWinInt.h makes declarations that are available on Windows only. * generic/tclBinary.c (TCL_NO_MATH): Deleted the generic/tclMath.h * generic/tclMath.h (removed): header file. The internal Tcl * macosx/Makefile (PRIVATE_HEADERS): header, tclInt.h, has a * win/tcl.dsp: #include <math.h> directly, and file external to Tcl needing libm should do the same. * win/Makefile.in (WIN_OBJS): Deleted the win/tclWinMtherr.c file. * win/makefile.bc (TCLOBJS): It's a vestige from matherr() days * win/makefile.vc (TCLOBJS): gone by. * win/tcl.dsp: * win/tclWinMtherr.c (removed):

* * The changes below fix SF bugs [593810], and [718045].andreas_kupries2003-04-221-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * generic/tclIO.c (Tcl_CutChannel, Tcl_SpliceChannel): Invoke TclpCutSockChannel and TclpSpliceSockChannel. * generic/tclInt.h: Declare TclpCutSockChannel and TclpSpliceSockChannel. * unix/tclUnixSock.c (TclpCutSockChannel, TclpSpliceSockChannel): Dummy functions, on unix the sockets are _not_ handled specially. * mac/tclMacSock.c (TclpCutSockChannel, TclpSpliceSockChannel): * win/tclWinSock.c (TclpCutSockChannel, TclpSpliceSockChannel): New functions to handle socket specific cut/splice operations: auto-initi of socket system for thread on splice, management of the module internal per-thread list of sockets, management of association of sockets with HWNDs for event notification. * win/tclWinSock.c (NewSocketInfo): Extended initialization assignments to cover all items of the structure. During debugging of the new code mentioned above I found that two fileds could contain bogus data. * win/tclWinFile.c: Added #undef HAVE_NO_FINDEX_ENUMS before definition because when compiling in debug mode the compiler complains about a redefinition, and this warning is also treated as an error.
* * 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.

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.

| | | | | | | | | * 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.
* TIP#91 implementation; makes old style channels binary compatible withdkf2002-05-241-53/+141

* * generic/tclEncoding.c: Fix typo in comment.mdejong2002-03-111-16/+18
| | | | | | | | * generic/tclIO.c (DoReadChars, ReadBytes, ReadChars): Use NULL value instead of pointer set to NULL to make things more clear. Reorder arguments so that they match the function signatures. Cleanup little typos and add more descriptive comment.
* * tests/encoding.test: added encoding-23.* testshobbs2002-03-021-4/+11
| | | | | | | * 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

| | | | | | | | | | | | | | | server sockets. [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.
* * Updated interfaces of generic/tclEncoding, generic/tclFilename.c,dgp2002-01-251-5/+5
| | | | | | | | | | | 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

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.
