Summary: "rev-parse --verify" is actually a terrible test, it only survived my test cases because I put garbage into the tables with RAND() or similar, not properly-formatted garbage. Use "cat-file -t" instead to ensure we perform an object-existence test. Test Plan: Ran "reconcile.php P" locally, ran "cat-file -t" and "rev-parse --verify" on properly-formatted but invalid hashes like "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", worked with @rguerin to resolve commit issues.

**reconcile.php** __repository_callsign__
|
|
Reconcile the state of Phabricator's caches with the actual state
|
|
of the repository.
|
|
|
|
This is an administrative/maintenace operation and not generally
|
|
necessary, but if repository history has changed or been rewritten
|
|
(for example, if the repository was stored from a backup)
|
|
Phabricator may think commits which are no longer present in the
|
|
repository still exist.
|
|
|
|
This will delete all evidence of commits which Phabricator can't
|
|
find in the actual repository.
