I got a patch from the django-cms folks that moves template loading into
their AppConfig.ready() routine, but the problem persists.
The last few lines of apps.populate are:
self.models_ready = True
for app_config in self.get_app_configs():
app_config.ready()
self.ready = True
At this point, django has the lock, app_config.ready() invokes the ready
code for my apps, and I'm back where I started (nested call to
apps.populate and deadlock).
In db/models/base.py, in model_unpickle, I see this:
if isinstance(model_id, tuple):
if not apps.ready:
apps.populate(settings.INSTALLED_APPS)
model = apps.get_model(*model_id)
Can that test instead be "if not apps.models_ready"? That would prevent
the nested call and fix my problem.
