[Codestriker-user] rdiff failed -- permission problem

[David C. <dcc...@gm...>]

On behalf of what user does the rdiff command run when using start and end
tags?  Currently I have two different deployments.  One of them allows me to
create a new topic using start and end tags.  The other does not, but I
can't see any difference.

For the deployment that doesn't work, I *can* run rdiff from the command
line and it works fine.  When I use codestriker, I get the following:

Problem generating topic text:

cvs rdiff: failed to create lock directory for
`/export/cvsroot/elvis/extreme/evpages'
(/var/lock/cvs/elvis/extreme/evpages/#cvs.lock): Permission denied
cvs rdiff: failed to obtain dir lock in repository
`/export/cvsroot/elvis/extreme/evpages'
cvs [rdiff aborted]: read lock failed - giving up

(Note that we have configured CVS to place locks outside the repository.)

Since I can run rdiff as user X from the command line, I know that I have
permissions to do so.  My theory is that when I create the topic and
Codestriker runs rdiff, it uses a different user and hence the problem.  I
tried adding 'apache' to our /etc/group, which is how we control who can
write a lock to /var/lock/cvs.  This did not help.

Any ideas about the user?  Any other potential reasons this should fail when
it works on the command line?  What else can I compare between the two
deployments besides the config files?

Thanks,
David
