[Koha-devel] Add ProxyTimeout to Plack Koha due to mod_cgi bug

[dcook at prosentient.com.au]

Hi all,

 

Last week, I discovered a bug in Apache httpd's mod_cgi. Basically, it means
that mod_cgi does not timeout until 2x the duration of TimeOut, while
mod_proxy_http (used by Plack) times out after 1x the duration of TimeOut.

 

You can see the details at
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=26400.

 

The Apache community worked very quickly, and together we've resolved the
bug, but I don't think Apache backport fixes.  

 

That said, there's been an open bug report in Debian for 5 years
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=780123). I'll send an
email in telling them that this has been fixed upstream. I wouldn't count on
a backport though.

 

In any case, the real importance here is that we harmonize people's
expectations. With Bug 15218, we started using CGI mode for certain
long-running processes. It might be that this isn't 100% necessary in all
cases, if we just increase the ProxyTimeout to match the effective TimeOut
time of CGI processes.
