This (action=query&format=json&prop=imageinfo&titles=File%3AExample.jpg&iiprop=comment) Imageinfo API query on File:Example.jpg returns null for the comment value. The expected value for comment should be: Minor tweak to text placement; diminish image height by 1 pixel. This was working as expected until a few days ago, when presumably, something broke. Please investigate, thanks.
Yeah, i'm guessing this bug is related to the epic reworking of how all the editsummaries are stored. T166732: Refactor comment storage in the database and abstract access in MediaWiki and T166733: Deploy refactored comment storage
I put together a patch that fixed the issue for me locally, and passes tests. How impactful is this API regression? Does it require an emergency deploy over the weekend or can it wait until Monday?
