Description

During various migration efforts in 2015/2016, a number of talk pages have the string {{#useliquidthreads:0}} added in order to disable LQT, but still have LQT threads associated. This has the effect of making those talk pages invisible.

Create a file that lists the changes necessary to re-enable LQT
- List the page title/ID, the contents to replace with, and the expected current revision ID
Create a file (or paste here, if short) of LQT threads which do not have a valid parent talk page

Here's a list of pages which LQT threads refer to, but which do not exist

$ bzcat missing-lqt-parents.json.bz2 | jq -r 'map( .pagetitle ) | sort | unique | .[]'

~~[P78439]~~

There's 295 threads which don't have a parent page:

I've pushed the code: https://gitlab.wikimedia.org/zoe/lqt-porting-tools/

Update: some of those pages did in fact exist. The source of the bug was that the LQT's idea of its parent thread was occasionally in the feminine, ie Utilizadora Discussão: instead of Utilizador Discussão: which is the canonical name in the page database.

This is an updated list of pages that shouldn't exist, and which I have now checked do not exist:

Currently reviewing that list, since LQT's weird style makes it hard to figure out what happened to lost topics. In the mean time feel free to continue with the other steps.

https://pt.wikibooks.org/wiki/Discussão:ATITUDES_DOS_NOSSOS_DIAS - a real instance of what we are trying to find, but harmless in this case; the parent page was correctly deleted, and the threads should also have been
https://pt.wikibooks.org/wiki/Ficheiro:EX21.shs is some sort of very odd DB corruption that some how has 12 threads with nothing in common attributed to it. All of them properly belong to other deleted pages.

The rest are all spam/vandalism/nonsense/orphaned talks were both the LQT thread and the topic were deleted years ago but somehow appeared in the API anyway (and now don't from my testing); I suspect LQT's "lazy updates" concept (https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/LiquidThreads/+blame/refs/heads/master/includes/Thread.php#991) is to blame, but no idea why.

TL/DR there is no cause for concern with that list of non-existent pages, all of them are properly nonexistent and it's fine to let the threads that point to them (if they still exist) to die when LQT is uninstalled with no further action.

Agreed. So, it looks like we're good to execute on these proposed changes in T397426 then!

Minor error, I'd made a field expect_revision instead of expected_revision. Fixed file:
