Summary:
Fixes T3217. Ref T776. Ref T1493. Broadly, this introduces a mechanism which works like this:
- When a repository is created, we set an "importing" flag.
- After discovery completes, we check if a repository has no importing commits. Basically, this is the first time we catch up to HEAD.
- If we're caught up, clear the "importing" flag.
This flag lets us fix some issues:
- T3217. Currently, when you import a new repository and users have rules like "Email me on every commit ever" or "trigger an audit on every commit", we take a bunch of publish actions. Instead, implicitly disable publishing during import.
- An imported but un-pulled repository currently has an incomprehensible error on `/diffusion/X/`. Fix that.
- Show more cues in the UI about importing.
- Made some exceptions more specific.
Test Plan:
This is the new screen for a completely new repo, replacing a giant exception:
{F75443}
- Created a repository, saw it "importing".
- Pulled and discovered it.
- Processed its commits.
- Ran discovery again, saw import flag clear.
- Also this repository was empty, which hit some of the other code.
This is the new "parsed empty repository" UI, which isn't good, but is less broken:
