I have a new Fedora 12 server that I am attempting to set up Mercurial on. I have yum installed mercurial, and most things seem to work fine. However, after setting up hgwebdir.cgi through apache, I am unable to do an hg push to the only repo currently being hosted. The error I get back is:

apache    1701  1691  0 13:19 ?        00:00:00 /usr/sbin/httpd

and I set permissions so that the apache user owns the whole repo and everything. In a last ditch attempt, I even made the repo globally writable.

I have a clone of the repo elsewhere on the machine running as a different user. If I set the the default value in the [paths] section of the clones hgrc file to the local filepath on the server, the push works fine, but if I switch it to use the url, I get the error every time.

Some possible quirks in how I've set this up... hgwebdir.cgi is sitting in /var/www/cgi-bin and the repo is a child of /opt/hg. I turned off suexec as well, and this doesn't seem to clear up the issue. The only line I added in the apache config to get hgwebdir running is:

ScriptAlias /hg "/var/www/cgi-bin/hgwebdir.cgi"

The hgweb.config is also in /var/www/cgi-bin and it's contents are:

[collections]
/opt/hg = /opt/hg

[trusted]
users = *

[web]
baseurl = /hg
push_ssl = false
allow_push = *

The repo browser is working fine, it's just push that doesn't work. Apache error_log doesn't have anything in about this error at all.
