Re: Re: Updating a WC in the post-commit fails

The Subversion server is run by the user who is starting the svnserve
process or the httpd Apache process depending upon if you're using
svn:// or http://. If you're using ssh+svn//:, each user runs the
svnserve process and thus the hook scripts. If you're on Linux/Unix,
you can use the "ps" or pgrep command.

What I found interesting is that everything worked until he deleted
his working directory and recreated it.

I can't say this is a permission issue, but my first instinct is to
make sure that I am operating as the user who is performing the
operation. It could be that the working directory was created by User
"A", but the Subversion server is running as User "B". And User "B"
can't update anything in the working directory because they don't have
write permission. Or maybe Subversion hook is waiting for someone to
put in the needed password.

I run a lot of various processes, and I will spend hours, sometimes
days, attempting to debug a problem before I realized that I setup a
particular piece of software as one user, but running it as another
