Unwriteable error when creating DR in Commons:Data
Closed, DuplicatePublic

Description

When attempting to raise a Deletion Request on [[Commons:Data:Copenhagen_Districts.map]], I have been getting the database locked error for about 30 minutes. Based on my other uploads in the same period, I can see that Commons did drop into read-only mode as part of replication, but I have made edits to Commons in that period. The issue may be with the Data space. Can anyone confirm if there is a deeper issue which is causing 'Commons:Data' to be unwriteable for an extended period? Or maybe the DR script cannot work on the Data space as it's JSON not wikitext; in which case there should be a better error trap or a work-around?

An error occurred while trying to do the requested action. To nominate this data for deletion, please edit the page to add the {{delete}} template and follow the instructions shown on it.

Update: I may be quite wrong about readonly. Checking my upload logs, Wikimedia Commons has been reporting as read-only in response to attempted API uploads since 6:34 through to now (10:40) UK time.

It appears at present that there is no way to add wikitext to that file that will cause it to be tagged for deletion, or as a copyvio, or anything really. We need at least one work-around.

As Data_talk pages are ordinary pages, for the example case I have raised https://commons.wikimedia.org/wiki/Commons:Deletion_requests/Data_talk:Kuala_Lumpur_Districts.map.

It is worth noting that "insource:" searches do not appear to work on Data pages, so even searching out matching files with problem sources is another layer of complexity for managing mass deletions.

I wonder if its related to deleting all the wikibase stuff in rc(?)

Rv my tag change. Wrong bug.

@Fae This task is probably unrelated to the slave lag read only mode issue IMO. I filed a separate bug T178094 for that issue.
