Issue #802 resolved

git: ChangesetDoesNotExistError only fixed by restarting apache

created an issue

I created a new branch made some modifications, pushed the whole thing, the changeset is showing in the summary and in the changelog but trying to access the changeset from the changelog tab raised a ChangesetDoesNotExistError. I restarted apache2 (i'm using mod_wsgi) and the changeset is now properly displayed.

here is the error I got:

    Yes, indeed:

    WSGIDaemonProcess pylons threads=4 python-path=/usr/local/lib/python2.6/site-packages user=www-data group=www-data

    I'll disable the threads part and check how it goes. Thanks

    Sorry if this is a separate issue, but I'm experiencing a similar problem using two RhodeCode 1.5.4 instances (with waitress) behind an Nginx proxy. Recent git commits show these errors, but seem to go away after maybe 5-10 minutes.

  3. Stephen Price

    That's a good point. Other than using separate ini files with unique instance id's, I didn't do anything to the cache settings. I assumed it'd shared the session data folder without any extra configuration. I'll review the docs again.

  4. Marcin Kuzminski repo owner

    Basically the only important thing is the unique IDs in .ini files. 5-10 minutes is to low for cache to expire, it looks like na issue with invalidating cache for both instances... You can check how many unique cache keys are present in repo settings when beein an super admin. Also try to delete all entries in cache_invalidation table and restart both instances. Maybe the cache table got polluted somehow

  5. Stephen Price

    Would clicking "invalidate repository cache" on that repo's settings page be enough?

    Would switching to a database-based cache be any better? I'm running PostgreSQL as RhodeCode's database.

  6. Marcin Kuzminski repo owner

    Clicking invalidate cache should immediately fix issues that you have with missing changesets. Switching to database-based cache shouldn't have any affect since the caches for the repos are kept in memory for each instance. Other caches are used for different things.

    Please clean the cache_invalidation table and restart instances
