Issue with copr git

[andersrh]

Hi.

I have tried to make a build this morning for our project because a new linux kernel release came out.

When I start the build I get 500 error from the copr git repo and the build fails.

log can be found here:

The same for all recent builds.

Thank you for the report @andersrh and @samoht0,
the issue is fixed now.

It was caused by a git package update, specifically:

 git                 x86_64        2.45.1-1.fc39          updates         53 k
 git-core            x86_64        2.45.1-1.fc39          updates        4.7 M
 git-core-doc        noarch        2.45.1-1.fc39          updates        2.9 M
 git-daemon          x86_64        2.45.1-1.fc39          updates        389 k
 perl-Git            noarch        2.45.1-1.fc39          updates         39 k

I think we should configure our servers to not run automatic security upgrades on weekends ...

Not sure what is the problem with the new git, so I only did

[root@copr-dist-git ~][PROD]# dnf downgrade git
[root@copr-dist-git ~][PROD]# dnf versionlock git

as a workaround until somebody can investigate the issue properly.

Hi @FrostyX

Thanks a lot :) it seems to be working now :)

[samoht0]

Yeah, working fine again. Thanks for the quick solution.

Red Hat Copr fix needed.

@FrostyX claims we should check if we can configure dnf-automatic for non-weekend times

The mentioned git update is now available

It didn't help but I can finally see the errors in the httpd log:

AH01215: stderr from /usr/libexec/git-core/git-http-backend: fatal: detected dubious ownership in repository at '/var/lib/dist-git/git/frostyx/foo/copr-cli.git'
AH01215: stderr from /usr/libexec/git-core/git-http-backend: To add an exception for this directory, call:
AH01215: stderr from /usr/libexec/git-core/git-http-backend:
AH01215: stderr from /usr/libexec/git-core/git-http-backend: \tgit config --global --add safe.directory /var/lib/dist-git/git/frostyx/foo/copr-cli.git

This is probably caused by the fact that the directory is owned by the copr-dist-git user and the web server is running under the apache user. Creating /etc/gitconfig with

[safe]
        directory = /var/lib/dist-git/git/frostyx/foo/copr-cli.git
        directory = .

works and makes it possible to clone the repository. For the record, I don't know what directory = . means.

The problem is that it is not possible to configure /var/lib/dist-git/git/ to be safe recursively and we would have to add every new repository manually. Not fun with our 789533 repositories.

The only thing that works is

[safe]
        directory = *

which completely disables the feature. Per man git-config:

To completely opt-out of this security check, set safe.directory to the string *. This will allow all repositories to be treated as if their directory was listed in the safe.directory list.

Which isn't ideal but may be fine in our situation?

I am keeping this open because I still want to send a message to git mailing list. But I deployed the fix and we are now running the up-to-date version of git, so technically, the issue is fixed.
