panettone: Leaking some kind of resource

Opened by tazjin at 2021-04-09T23·07+00

Panettone seems to be leaking some kind of resource:

This problem is relatively new, might be related to the email thing.

  1. Okay, doing several different things because I'm annoyed by this today (I linked panettone somewhere publicly and it went down).

    My first theory is that we may be leaking LDAP connections when checking user auth. I'm trying out cl/5193 for this.

    My second theory is that our custom handling of threads & postgres connections is wrong. I'm making a change that replaces this with postmodern's native connection pooling. In fact I'm posting this comment from an instance of panettone running that change, so it seems to be working.

  2. We may now have fixed this, but it's hard to say until this version of panettone has been running for a few days.

  3. Fixed in cl/5772 and the other one that refactored DB stuff. No more leaky resources, because no more LDAP.
