Hello,
I'm encountering the infamous "no repositories found" issue. I've
exhaustively checked permissions, up to and including assigning a shell
to the www-data user and verifying that it can read my Git repositories.
I've checked every directory permission from /, and it all looks good.
One complicating factor of my setup is that it is in Docker
(http://docker.io) containers. I currently have a Docker container
hosting Git repositories via Gitolite, another running Jenkins, and
Cgit. Jenkins communicates with Gitolite just fine, though it uses SSH
which I know works.
It would be very helpful if Cgit gave me an exact error as to why it
can't access my repositories. I had to jump through a hoop with Selinux
on 13.10 in the Gitolite container, so if that's tripping up Cgit for
some reason then knowing would be helpful.
Is there any way to get detailed error logs? I don't see any in my
Apache logs, which could mean a misconfiguration on that end. But having
access to some sort of detailed error log would be very helpful in
debugging this.
Thanks.

How is CGit able to see the repositories? Unlike Jenkins, CGit does not
speak any of the Git protocols, it expects to see repositories in the
file system.
Are you Docker containers sharing an underlying filesystem, or do you
have some external job that is cloning the repositories for CGit?

Since CGit is a CGI program, you can just run it and see what happens.
You may want to export PATH_INFO=/ before doing so to make sure it
generates the index.
You can run under strace to monitor what is going on during repository
discovery.

OK, new complicating factor. If I spin up a container that I can
interact with (I.e. running a shell) then running cgit.cgi directly
shows my repositories. If I spin up a non-interactive container (I.e.
running in the background) then I see no repositories. The only
difference between these environments should be the lack of an attached
stdin/stdout.
So is there any way to redirect CGI errors to the Apache error log? I
have the following in my configuration:
LogLevel info
CustomLog |cat combined
My assumption is that this will redirect all relevant logs to stdout so
they are visible in the "docker logs" command. But I only see server
accesses, no CGI errors.
Thanks.

OK, figured it out. I was proxying to the Cgit docker container via
Nginx, and specified:
proxy_pass http://cgit.prod.docker;
instead of:
proxy_pass http://cgit.prod.docker/;
Maybe some sort of "debug mode" might have helped diagnose the issue?
Presumably Cgit was looking for repositories in a directory that didn't
exist. Having a way to output "No repositories found in
/srv/git/doesnotexist" might have helped me track that down more
quickly. Or maybe such a thing exists and my Google powers are weak. :)
Thanks.

CGit does log "Error opening directory" if either the directory
specified to scan does not exist or a directory listed in the project
list does not exist.

Is there any chance that the CGIT_CONFIG environment variable is defined
differently for the two invocations? If it is not defined then CGit
will default to a built-in location (by default /etc/cgitrc).

I have never tried using a CustomLog like that, but with a default
logging setup I do see CGit errors in /var/log/apache2/error_log.
