@modify_settings repopulates apps that register type handlers and hits the database to select OIDs (if not cached).

I'm super confused. Shouldn't Jenkins have picked this up earlier, i.e. when fbd16438f46bc2128926958ad24331da5d1b406f (#33143) was merged?

comment:3 by Mariusz Felisiak, 8 months ago

Shouldn't Jenkins have picked this up earlier, ...

No, it shouldn't. First of all we run the entire test suite not random subsets of test classes. Secondly, this is quite tricky and you have to debug how types are registered for django.contrib.postgresql and how @modify_settings works:

  • types are registered when connection is created by connection_created handler, so it's not when app is initialized, so far so good,
  • when @modify_settings manipulates INSTALLED_APPS then we undo effects of PostgresConfig.ready(),
  • @modify_settings calls PostgresConfig.ready() again, tries to registered handlers for existing connections and hits the database to select OIDs.

Maybe worth noting: for me this depends on the --parallel option with --parallel 1 producing even more errors:

--parallel 2 no errors:

comment:5 by Florian Zimmermann, 8 months ago

First of all we run the entire test suite not random subsets of test classes.

So it's expected that the tests behave differently when I only run a subset of them? I can't even reproduce this if I just run the failing tests by themselves...

Replying to Florian Zimmermann:

So it's expected that the tests behave differently when I only run a subset of them?

Of course it's not, that's the issue. The way how @modify_settings and initializing django.contrib.postgres work are non trivial. We have here a long standing isolation issue, revealed by fbd16438f46bc2128926958ad24331da5d1b406f.

comment:7 by David Sanders, 8 months ago

@Florian to demonstrate the issue, you can make the postgres tests fail with --parallel=1 if you replace the lines getting type oids with their underlying non-cached versions (get_hstore_oids() and get_citext_oids() are cached so when it comes time to reload the module there's no db interaction for a single process)

Eg this diff shows what I mean (I'm using psycopg2 so I've replaced it in the psycopg2 block)
