* The write and flush operations of reflected transforms ([chan push]) havedgp2014-07-081-2/+2
| | | | | | | been converting all lower level channel errors from Tcl_WriteRaw() into EINVAL. Generally this is a perplexing discard of useful information, but worse it interferes with the EAGAIN signalling that is required to manage the BLOCKED state of a nonblocking channel. Thanks to aspect for demo scripts that pointed to the bug.

* * generic/tclIORTrans.c (ReflectInput): Fixed a bug triggered byandreas_kupries2008-06-101-3/+6
| | | | | | | | | | | Pat Thoyts <patthoyts@users.sourceforge.net>. Reset the EOF flag after draining the Tcl level into the result buffer, to make sure that the result buffer will be drained as well by repeated calls to ReflectInput should it contain more than one buffer-full of data. Without that reset the higher I/O system will not call on ReflectInput anymore due to the assumed EOF, thus losing the data which did not fit in the buffer of the call which caused the eof and drain.
* TIP #230 IMPLEMENTATIONandreas_kupries2008-06-061-0/+3345
* generic/tclIOCmd.c: Integration of transform commands into 'chan' ensemble. * generic/tclInt.h: Definitions of the transform commands. * generic/tclIORTrans.c: Implementation of the reflection transforms. * tests/chan.test: Tests updated for new sub-commands of 'chan'. * tests/ioCmd.test: Tests updated for new sub-commands of 'chan'. * tests/ioTrans.test: Whole new set of tests for the reflection transform. * unix/Makefile.in: Integration of new files into build rules. * win/Makefile.in: Integration of new files into build rules. * win/makefile.vc: Integration of new files into build rules. NOTE: The file 'tclIORTrans.c' has a lot of code in common with the file 'tclIORChan.c', as that made it much easier to develop the reference implementation as a separate module. Now that the transforms have been committed the one thing left to do is to go over both modules and see which of the common parts we can factor out and share.
