Hi there, if you mean
https://gitweb.mageia.org/ by gitweb then that is only for our Mageia-specific software projects and management of our infrastructure and websites.
It does not contain the version control for the actual packages that are installed on your system. Those are contained in our SVN:
https://svnweb.mageia.org/packages/If you want to submit a patch, then the most useful thing would be to create a bugreport, and attach a patch against the SVN checkout of the package which contains the file.
In this case it's mageia-theme:
http://svnweb.mageia.org/packages/cauld ... iew=markupWithout being a packager you cannot commit to our SVN, and submitting a patch via a bugreport would be the closest to a pull request as in github.
FWIW there were similar bugreports about this, but those were either closed by the reporter or closed as old due to no replies. Last one:
