eschutho opened a new pull request, #34584:
URL: https://github.com/apache/superset/pull/34584
### SUMMARY
Added defensive initialization checks to prevent application startup
failures
when database tables haven't been created yet. The application now
gracefully skips database-dependent features during initialization if the
database is not ready, allowing successful startup even before migrations
have run.
The key change is the introduction of a
`_init_database_dependent_features()`
method that checks for table existence before attempting to initialize
features like the tagging system and theme seeding. This prevents
`OperationalError` exceptions that would otherwise crash the application
during startup.
### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
Not applicable - backend initialization change only
### TESTING INSTRUCTIONS
1. Run the new unit tests: `pytest tests/unit_tests/initialization_test.py
-v`
2. To manually test the fix:
- Start with a fresh database (no tables created)
- Start the Superset application
- Verify the application starts without errors
- Check logs for: "Superset tables not yet created. Skipping
database-dependent initialization"
- Run migrations: `superset db upgrade`
- Restart the application
- Verify all features initialize properly
