Summary: @rguerin ran into an issue in his install where Phabricator appears to have discovered commits which no longer exist, and thus is failing to proceed with its repository import. It's not clear how we got into this state. Previously, it was possible by, e.g., parsing a different repository's working copy and then switching them back, but there are now safeguards against that. I'm taking a three-pronged approach to try to sort this out: - Provide a script to get out of this state (this script) and reconcile Phabricator's view of a repository with an authoritative copy of it. This basically "un-discovers" any discovered commits which don't actually exist (any queued tasks to parse them will fail permanently when they fail to load the commit object). - Add more logging to the discovery daemon so we can figure out where commits came from. - Improve Diffusion's UI when stuff is partially discovered (T776). (This script should also clean up some nonsense on secure.phabricator.com from a botched Diviner import.) Test Plan: Ran "reconcile.php" with bogus commits and bogus differential/commit links, had them expunged. Will work with @rguerin to see if this resolves things.

**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.
