Try to handle multiple connections better.
The session database is a hot spot. When multiple requests (e.g. 20)
come in at the same time session database contention can get great.
The original code didn't retry session database access when the open
failed. This resulted in errors at the client.
The second pass delayed 0.01 seconds and retried. It was better but we
still had multiple second stalls. I think the first request got in,
everybody else backed up and then retried at the same time. Again they
stepped on each other. With logging I would see many counters go all
the way to low single digits or to -1 indicating falure.
This pass uses randomint to generate delays from 0-.125 seconds in 5ms
increments. This performs better in testing. I rarely saw a counter
less than 13 (2 failed retries). Current logging starts after 6
failures and counts down until success or failure.

This directory has some detector examples that you can use to get ideas on implementing your own detectors. These are provides on an as-is basis. When they were added, they worked for somebody and were considered a useful example. The roundup team will attempt to keep them up to date with major changes as they happen, but there are no guarantees that these will work out of the box. If you find them out of date and have patches to make them work against newer versions of roundup, please open an issue at: https://issues.roundup-tracker.org The current inventory is: creator_resolution.py - only allow the creator of the issue to resolve it emailauditor.py - Rename .eml files (from email multi-part bodies) to .mht so they can be downloaded/viewed in Internet Explorer. irker.py - communicate with irkerd to allow roundtup to send announcements to an IRC channel. newissuecopy.py - notify a team email address (hardcoded in the script) when a new issue arrives. newitemcopy.py - email the DISPATCHER address when new issues, users, keywords etc. are created. Kind of an expanded version of newissuecopy.
