Description

Apologies if I use bad terminology here; I'm confused.

I am using a tool (atlantis) which tries to clone a PR and do some local work. This usually works, but fails to clone PRs that were created using the Agit workflow.

I created a PR as follows:

% git push origin HEAD:refs/for/main -o topic="agit-test" -o title="Test agit workflow"
Enumerating objects: 5, done.
Counting objects: 100% (5/5), done.
Delta compression using up to 64 threads
Compressing objects: 100% (3/3), done.
Writing objects: 100% (3/3), 530 bytes | 530.00 KiB/s, done.
Total 3 (delta 2), reused 0 (delta 0), pack-reused 0 (from 0)
remote: 
remote: Create a new pull request for 'infinoid/agit-test':
remote:   https://gitea.server/tf/repo/pulls/8
remote: 
remote: . Processing 1 references
remote: Processed 1 references in total
To https://gitea.server/tf/repo
 * [new reference]   HEAD -> refs/pull/8/head

The tool got a webhook notification, saw the new PR and tried to clone it. That failed:

running git clone --depth=1 --branch refs/pull/8/head --single-branch https://atlantis:<redacted>@gitea.server/tf/repo.git /atlantis-data/repos/tf/repo/8/default
Cloning into '/atlantis-data/repos/tf/repo/8/default'...
warning: Could not find remote branch refs/pull/8/head to clone.
fatal: Remote branch refs/pull/8/head not found in upstream origin
: exit status 128

What is the right git clone command to clone an Agit PR? The above command didn't work, and the AGit documentation doesn't have any specific details about cloning.

Apparently the PR head ref is not visible to clients. Is this expected? The Agit workflow seems quite magical, so I don't really understand it. My best guess is that the staging branch was created under a fork with a different owner (infinoid/, not tf/), but it's not outwardly visible, or if it is, the webhook doesn't point at the right location, or the tool misunderstood the webhook data somehow.

The gist link has container logs, and the json webhook content that was sent to the tool.

Thanks!

@Infinoid commented on GitHub (Dec 4, 2024):

The "git fetch" syntax does work, thanks for pointing it out.

When I make an Agit PR (number 9 in this repo) and a normal PR (with branch name pr-test), and diff the two webhooks, I see:

     "head": {
-      "label": "",
-      "ref": "refs/pull/9/head",
+      "label": "pr-test",
+      "ref": "pr-test",

So that explains why the tool works for normal PRs; it was using a branch name, not the PR ref.

I'll follow up with the tool authors, thanks!
