| | | | | | | patch for [SF Tcl Bug 1359094]. This moves the retrieval of the next channel state to the end of the loop, as the called closeproc may close other channels, i.e. modify the list we are iterating, invalidating any pointer retrieved earlier.

| | | | | | | | | | * tests/io.test: changed from ten bytes to one byte. Need * tests/iogt.test: for this change was proven by Ross Cartlidge <rossc@cisco.com> where [read stdin 1] was grabbing 10 bytes followed by starting a child process that was intended to continue reading from stdin. Even with -buffersize set to one, nine chars were getting lost by the buffersize over reading for the native read() caused by [read].

* * generic/tclIO.h (CHANNEL_INCLOSE): New flag. Set inandreas_kupries2004-07-151-1/+48
| | | | | | | | | | | | | | | | | | | | | | * 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.
* Removed one bogus clearance of the has-more flag. Erroneously keptandreas_kupries2004-05-191-3/+1

* * tclIO.c: Fixed [SF Tcl Bug 943274]. This is the same problem asandreas_kupries2004-05-191-6/+91
| | | | | | | | | | | | | * 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.

| | | | | | | 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 (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.

* * 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

[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.

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].
