Stale UNIX socket files will prevent mod_wsgi starting up in daemon mode. #77

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
When running mod_wsgi daemon mode, UNIX sockets are created for communicating 
between 
Apache child processes and daemon processes. When Apache is shutdown normally 
the UNIX 
sockets would be removed. If however the Apache parent process crashes, or the 
machine itself 
crashes, then the UNIX socket files wouldn't be removed.

This can cause an issue if when Apache is started at a later time , possibly 
after a reboot, and the 
same UNIX process ID is used for the Apache parent process. In particular, the 
stale UNIX socket 
file will exists and mod_wsgi will not be able to create new UNIX socket in its 
place.

Solution would be to remove any existing UNIX socket file before creating it.

Fix should possibly be back ported to mod_wsgi version 2.X branch for inclusion 
in 2.1.

Fixed in revision 942 of trunk for 3.0.

Should still consider it for backporting later on if urgent need to bring out 
2.2.
