Summary:
- When you have an un-cloned repository, we currently throw random-looking Git/Hg exception. Instead, throw a useful error.
- When you have a cloned but undiscovered repository, we show no commits. This is crazy confusing. Instead, show commits as "importing...".
- Fix some warnings and errors for empty path table cases, etc.
Test Plan:
- Wiped database.
- Added Mercurial repo without running daemons. Viewed in Diffusion, got a good exception.
- Pulled Mercurial repo without discovering it. Got "Importing...".
- Discovered Mercurial repo without parsing it. Got "Importing..." plus date information.
- Parsed Mercurial repo, got everything working properly.
- Added Git repo without running daemons, did all the stuff above, same results.
- This doesn't improve SVN much but that's a trickier case since we don't actually make SVN calls and rely only on the parse state.
