fix: dataset update permission out of sync #25043

zephyring · 2023-08-21T16:17:23Z

SUMMARY

The perm and schema_perm attributes for dataset model is out of sync due to unreliably using sqlalchemy get_history method where the history state depends on whether the session has flushed or not.
Previously we have logic in before_update and after_update and permission sync logic in after_update will not be deterministic due to session flush.

This PR moves permission sync logic into before_update and directly using connection.execute to check current db state instead of relying on session state to make sure we can detect actual db/table/schema changes to trigger permission update.

It also clean up shadow_dataset_write logic out as we no longer support it but the database attribute is still not lazily loaded when dataset.database attribute is accessed. Thus I leave the load_database method there still.

We also have unique constraints at db layer for (db, schema, table) tuple

No tests?

LGTM! I still think it would be best to eventually move this logic into the DAO layer, but this is a great way to get things working properly consistently with sqlalchemy events.

To @craig-rueda's point, there are several existing tests prefixed test_after_update_dataset that test this functionality. I'm not sure any new tests are needed since this PR is pretty much just a refactor/improvement of this existing functionality, but it would probably be good to rename them to test_before_update_dataset to be consistent with naming

agreed. Consolidating to domain's command layer is likely the better way of handling side effect like permission update, as there's existing patterns here.
But I would defer the problem to a larger refactoring until we all agree upon ideal state/target state of how permissions system should work in Superset.

This PR is purely continuing with existing patterns but more on a fix side of thing.

Thanks for ensuring we're using the same session.

+        # we set a property


this is an important change to the base update method.
By creating a out of session copy of the original model instance, we can set attributes on the copy without worrying the before/after update sqla listener will be triggered for each property.

The listener will only be triggered when session is committed

there's one test test_run_sync_query_dont_exist that I cannot get passed by with this baseDao.update method change(using a copy model instance out of session and merge)
We probably need more thoughts on how to reduce number of events triggered on each property update, thus reverting here

Thanks @zephyring!

nice! just one comment, would be nice to have a test also to assert what changed on this PR
