The windows pipe driver + now has the same behavior as the UNIX side. This change is + to avoid a hung shell when exiting due to open pipes that + refuse to close in a graceful manner. + * doc/open.n: Added a note about -blocking 0 and lack of + exit status as it had never been documented. [Bug 947693] + + ***POTENTIAL INCOMPATIBILITY*** + + Scripts that use async pipes on windows, must (like the + UNIX side) set -blocking to 1 before calling [close] to + receive the exit status. + + * tests/winPipe.test (winpipe-6.1/2): added 'fconfigure $f + -blocking 1' so the exit status can be acquired. + 2005-04-13 David Gravereaux <davygrvy@pobox.com> * generic/tclIO.c (Tcl_SetChannelBufferSize): Lowest size limit |
