The tools available on GitHub are fantastic for reviewing code changes, but less so for checking out those code changes on your local machine to build and test them.
With a simple tweak to your
.git/config file in a clone of the
Cisco-Talos/clamav repository, you can simply check out another developer's pull request as a branch to build and test it.
First, if you don't already have a clone of the upstream repository, do this:
git clone https://github.com/Cisco-Talos/clamav.git
Then, in your favorite text editor, open
.git/config and add the following line at the end of the
[remote "origin"] section. Don't delete or replace anything, just add the following line:
fetch = +refs/pull/*/head:refs/remotes/origin/PR-*
Tip: The above works for GitHub Cloud and GitHub Enterprise servers. If you happen to work with GitLab or BitBucket, you can do this instead for the same effect:
For BitBucket repos:
fetch = +refs/pull-requests/*/from:refs/remotes/origin/PR-*
For GitLab repos:
fetch = +refs/merge-requests/*/head:refs/remotes/origin/PR-*
Now you may run the following to test the pull request. Substitute
# with the pull request number found on the website:
git checkout PR-#
At this point, you should find yourself in a branch containing the PR contributor's changes.
