Problem with `git instaweb` on OpenSUSE Tumbleweed: No such projects found

Question

I am having trouble setting up git instaweb on OpenSUSE Tumbleweed.

I did install git-web and lighttpd.

When I do git instaweb in the root of my git project, the browser opens in a page that says No such projects found.

I tryed to put the project root in /srv/git but it also did not work.

This should be as simple as doing these commands in the project root:

git instaweb

and

git instaweb --stop

Answer 1

To solve this issue, I have noticed that the command git instaweb creates a folder under .git called gitweb. In this folder we can find a configuration file for lighttpd called lighttpd.conf and another for gitweb.cgi called gitweb_config.perl.

Assuming you are in the root of the project, it is possible to run lighttpd "by hand" like this:

lighttpd -D -f .git/gitweb/lighttpd.conf

• -f specifies the lighttpd configuration file.
• -D tells lighttpd not to daemonize.

When I access the browser page, I get on the console:

[Fri Jan  5 17:51:35 2024] gitweb.cgi: Can't exec "/usr/bin/git": Permission denied at /usr/share/gitweb/gitweb.cgi line 3335.

It seems to be a problem with /usr/bin/git. I tried to add the following line to /etc/apparmor.d/usr.share.git-web.gitweb.cgi:

/usr/bin/git rix,

But it still did not work. After some searching I found a way to debug AppArmor:

grep -i apparmor\=\"DENIED\" /var/log/audit/audit.log | less
...
type=AVC msg=audit(1704485570.756:138288): apparmor="DENIED" operation="exec" class="file" profile="gitweb.cgi" name="/usr/libexec/git/git" pid=31445 comm="gitweb.cgi" requested_mask="x" denied_mask="x" fsuid=1000 ouid=0

So I deleted the previously added line to /etc/apparmor.d/usr.share.git-web.gitweb.cgi and added the following line:

/usr/libexec/git/git rix,

Now it works fine.
