2025-11-04Fixed #36652 -- Increased determinism when loading migrations from disk.Jayden Kneller
Ordering still depends on pkgutil.iter_modules, which does not guarantee order, but at least now Django is not introducing additional indeterminism, causing CircularDependencyError to appear or not appear in some edge cases. Co-authored-by: Jacob Walls <jacobtylerwalls@gmail.com>
2025-07-23Refs #36500 -- Rewrapped long docstrings and block comments via a script.django-bot
Rewrapped long docstrings and block comments to 79 characters + newline using script from https://github.com/medmunds/autofix-w505.

2020-12-31Fixed #31413 -- Fixed isolation of migrations.test_loader on databases that ↵Hasan Ramezani
don't support transactions.
2020-12-29Fixed #32302 -- Allowed migrations to be loaded from regular packages with ↵William Schwartz
no __file__ attribute. The migrations loader prevents the use of PEP-420 namespace packages for holding apps' migrations modules. Previously the loader tested for this only by checking that app.migrations.__file__ is present. This prevented migrations' being found in frozen Python environments that don't set __file__ on any modules. Now the loader *additionally* checks whether app.migrations.__path__ is a list because namespace packages use a different type for __path__. Namespace packages continue to be forbidden, and, in fact, users of normal Python environments should experience no change whatsoever.
2020-07-22Reverted "Fixed #30300 -- Allowed migrations to be loaded from directories ↵Tim Graham
without __init__.py file." This reverts commit 3cd3bebe8921e14b911b36b2a1cbceef8fb6294e.
2020-04-22Fixed #31499 -- Stored ModelState.fields into a dict.Simon Charette
This allows the removal of its O(n) .get_field_by_name method and many other awkward access patterns. While fields were initially stored in a list to preserve the initial model definiton field ordering the auto-detector doesn't take field ordering into account and no operations exists to reorder fields of a model. This makes the preservation of the field ordering completely superflous because field reorganization after the creation of the model state wouldn't be taken into account.
2019-10-10Fixed #30300 -- Allowed migrations to be loaded from directories without ↵Benjy Weinberger
