IPC::Open2, mod_perl and cvsweb
Hi!
I was wondering if there are any known issues regarding IPC::Open2 with mod_perl. I recently put cvsweb.cgi under mod_perl for our cvs server and found problems where with the cvsweb.cgi attempting to close the logfile. The statement looks like this:
close($reader) or warn "cannot close: $!"; # i changed die to warn so i could look at my log file
the log file error reported:
cannot closing Broken pipe at /var/apache/data/cvsweb/run.cgi line 1674.
I dumped the script back under a normal cgi directory for which the script operated normally. I'm not sure why exactly this is causing a broken pipe. The directories that are being used have been chmod'd so that cvs annotate can write the lock file to them (otherwise the normal CGI version wouldn't work either). So I've pretty muched narrowed it down to mod_perl and IPC::Open2.
Has anyone else experienced this issue with cvsweb and mod_perl?
Thanks!
-keith

GY> IPC::Run++
Question about IPC::Open2 under mod_perl seems to arise quite
frequently. Maybe it should be added to mod_perl guide in 'Frequent
mod_perl problems' section.

Seconded. Go with IPC::Run and you won't regret, since it works under
mod_perl and gives you much more than the IPC::Open* family.

Look in archives. I think many people had problems with IPC::Open2
under mod_perl. So far the best solution I know is just replacing it
with IPC::Run.
