Presently I'm trying to understand what effect the convertAllLqtPages.php script will do when faced with a "frozen" set of pages. If I have understood it correctly, what the script does is kind of orthogonal to whether or not the LQT pages can be edited: on a frozen wiki it will still quite happily take those pages and import them into Flow. If the intention is to have somewhere to safely do a dry-run, I don't think that would be the right way to go about it.

If by frozen you mean https://github.com/wikimedia/operations-mediawiki-config/blob/bb48e35598c79ef5dc0524973c9d3ac35336f604/wmf-config/liquidthreads.php#L6 then the script would do nothing because the way freezing is implemented is by forcibly making all LQT pages not actually LQT (wgLiquidThreadsAllowUserControl = false disables the useliquidthreads parser function).

Ah – thank you for the clarification. It sounds like it wouldn't really aid us much as a dry run, then.

hye @zoe – can you please update this ticket to reflect the current status of this work?

ppelberg moved this task from Ready to Be Worked On to Blocked / Needs More Work on the Editing-team (Kanban Board) board.Aug 18 2025, 4:45 PM

Not Zoe, but my understanding is that once T397426 is done (and the community is informed etc.) you should be ready to run LQT conversions on ptwikibooks without any further prep work.

I tested that the code works as it should and submitted a few patch fixes above, and was (IIRC) satisfied after that.

@Pppery: my plan for this morning involved asking you what you thought, and you're way ahead of me!

@ppelberg: I think we can close this one, then?
