1979543 - Farm Merge Valley does not work anymore

Status: RESOLVED DUPLICATE of bug 1978673

(Web Compatibility :: Site Reports, defect, P1)

Description

[KLWytRayaJGtjRXXidQJ]

Attachment: farm_merge_valley_firefox141_bug.webm

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:141.0) Gecko/20100101 Firefox/141.0

Steps to reproduce:

Visited https://www.crazygames.com/game/farm-merge-valley with a brand new profile, and attempted to play the game.

Actual results:

The game requires a lot of clicking and dragging of the game board, but instead of the game board moving around when being dragged, it turns translucent and detaches as if Firefox thinks it's an image that could be dragged to the desktop.

Expected results:

The game board should be maneuverable by dragging it, but sometimes it isn't. The problem is intermittent. Note that even though my computer is ancient, the game worked fine for months with older Firefox versions through 140.

This is indeed a regression, bisecting.

Comment 2

[Kagami Rosylight [:saschanaz] (they/them)]

Ok, this falls between the 2025-06-14 and 2025-06-15, and given that's the git migration day (edit: but was it? I think it was earlier...), mozregression panics without entering autoland bisect 😞

[Kagami Rosylight [:saschanaz] (they/them)]

Zeid, any idea how to bisect across the merge commit? (I can do a manual bisect by downloading artifacts from treeherder, but that doesn't sound like a good use of time...)

Comment 4

[Zeid [:zeid]]

:saschanaz -- trying to reproduce to see what the issue is.

Comment 5

[Zeid [:zeid]]

Can you be more specific as to what the command you are running is, and what the error output is, which might help me diagnose.

Comment 6

[Kagami Rosylight [:saschanaz] (they/them)]

Sure, I get this from GUI when trying to bisect between 2025-06-14 and 2025-06-15:

Comment 7

[Zeid [:zeid]]

It looks like mozregression is trying to use the Lando/Phabricator branch name (firefox-autoland) instead of autoland and firefox-main instead of mozilla-central when parsing the merge commit. There needs to be a code change in order to fix this issue, I will see if I can push a dev release to have a temporary fix.

Comment 9

[Zeid [:zeid]]

You should be able to try installing this for a temporary workaround:

pip install git+https://github.com/mozilla/mozregression.git@zeid/bug-1979543-add-mapping-for-merge-commit-repos

Comment 10

[Kagami Rosylight [:saschanaz] (they/them)]

I made a progress with the workaround, thank you!

I got a bunch of "Skipping build" warnings, but at the end it worked anyway, so maybe those are red herrings?

I think the point it was crashing at was where the repo name was going to be used for querying the pushlog, which still uses the old repo names, so I think this should be fine and those may be red herrings.
