epriestley ee1e2da8fb Avoid Timeline race condition ... Summary: While I should fix the transactional stuff, that patch is going to be tricky and transactions have some performance implications. This is a simple fix which prevents the race. Instead of having the data point at the event ID, have the event point at a data ID. Insert the data first, then insert the event with the right data pointer. This is super simple and prevents the race issue. Test Plan: - Ran the schema upgrade script, verified that the database was correctly upgraded. Was also prompted to stop daemons. - Ran 'repository-launch-master', verified that the discovery daemons were able to discover new commits and insert events for them. Verified the committask daemon was consuming events and converting them into tasks. - Verified new tasks looked correct in the database. - Browsed web interface.
