Use git rev-list --first-parent when checking out git repositories when CLEANDATE is set (!71) · Merge requests · clean-and-itasks / clean-build

Merged Camil Staps requested to merge fix-CLEANDATE into master Mar 09, 2021

This way we only check out a previous state of the requested branch.

For example, if the history looks like:

* (merge) commit 4
|\
| * commit 3
| |
| * commit 2
|/
* commit 1

If a commit before 3 is requested, previously, commit 2 would be selected. With --first-parent, we only follow the left path, and commit 1 is selected. This avoids checking out the intermediate state on a feature branch.
