Closed samholmes closed 3 years ago
To answer my own question, these branches are created on lines 18 and 19 (https://github.com/13rac1/block-fixup-merge-action/blob/master/entrypoint.sh#L18).
Can this be closed? Seems like it. 😉
Sure, this can be closed. Though I resolved a problem that was in my fork of this project: https://github.com/samholmes/block-wip-pr-action/pull/2 Perhaps it’s relevant here as well. The problem was that if the base branch was ahead of the PRs merge base, then the depth wouldn’t be large enough to get to the merge base, and the fetch for the PR branch would go to init. If there are any fixup/squash commits in the trunk (accidental commits prior to adding the action to protect), then the action would fail.
Ah interesting, that is a problem. Oh edge cases...
Increasing the depth to 500 as you've done will (can?) result in significantly more data transfer on some repositories and therefore longer run times:
/usr/bin/git -c protocol.version=2 fetch --no-tags --prune --progress --no-recurse-submodules --depth=500 origin "${BASE_REF}:__ci_base"
This solution works, but I wonder if there's a more efficient process? 🤔
Start with a lower depth and increase it until git merge-base __ci_pr __ci_base
is not a merge commit? Just idea I haven’t tried yet.

When looking at the
entrypoint.sh
source, I noticed refspecs containing__ci_base
and__ci_pr
(https://github.com/13rac1/block-fixup-merge-action/blob/master/entrypoint.sh#L26), but I cannot find any documentation on these tags (I assume they're tags). I'm noticing issues where thegit log __ci_base..__ci_pr
command is returning a list of commits farther back than the base ref.
