[Bug 480799] New: man/groff: output to pipe is broken
https://bugzilla.novell.com/show_bug.cgi?id=480799 Summary: man/groff: output to pipe is broken Classification: openSUSE Product: openSUSE 11.1 Version: Final Platform: All OS/Version: Linux Status: NEW Severity: Major Priority: P5 - None Component: Development AssignedTo: pth@novell.com ReportedBy: jengelh@medozas.de QAContact: qa@suse.de Found By: Beta-Customer I noticed that output to a pipe randomly outputs (or not), there being totally broken. This affects even a simple testcase such as the infamous Useless Use Of Cat: man ls | cat For other manpages - maybe it is related to length of the page - it works: man bash | cat (This can be used to produce a text/plain file of a manpage, using e.g. man -l foobar.8 | perl -pe 's/.\cH//g' >foobar.txt) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Please show what the command `printenv' writes out. Next I'd like to know is what kernel are you running, that is the output of `uname -a' .. beside this please set ulimit -c unlimited before trying to recur the broken pipe.

As you may read from the manual page of socketpair(2) and info libc 'Socket Pairs' it can be used as replacement for pipe(2). If this is not posssible anymore the related kernel is broken. Btw: the kernel of openSuSE 11.1 is 2.6.27 (e.g. 2.6.27.7 upto 2.6.27.19). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
