Gazzetta Extensions: DP, Itcl, Img CustomShell: tons of changes, but none related to the problem ReproducibleScript: tclsh set f [ open "|tclsh" r+ ] [... kill the tclsh externally ...] flush $f [... system gets to 100% workload because flush is ignoring errors ...] ObservedBehavior: see above the relevant information is in the file tclWinChan.c and tclWinPipe.c. There, we see things like: TclWinConvertError(GetLastError()); if (errno == EPIPE) { return 0; } where EPIPE is a placeholder for all pipe errors. This behavior doesn't make sense. Removing the incriminated lines seems to bring relief, but we need to know if there is any reasons for those lines to show up. -- 8.2.0 adds PIPE_EOF to the flags, and has many other rewrites to fix these problems. -- 10/19/1999 hobbs ---------------------------------------------------------------------- You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=110894&aid=218538&group_id=10894 |
