Summary:
Fixes T5839. If a repository has been force pushed and garbage collected, we might have a ref cursor in the database which still points at the old commit (which no longer exists).
We'll then run a command like `git log <new hash> --not <old hash>` to figure out which commits are newly pushed, and this will bomb out because `<old hash>` is invalid.
Instead, validate all the `<old hash>` values before we try to make use of them.
Test Plan:
- Forced a repository into a bad state by mucking with the datbase, generating a reproducible failure similar to the one in T5839.
- Applied patch.
- `bin/repository update <callsign> --trace` filtered the bad commit and put the repository into the right state.
- Saw new commits recognized correctly.
- Ran `bin/repository update <callsign>` for a Mercurial and SVN repo as a sanity check.

Test Plan: For at least one of our repositories, this patch fixes the `Unknown commit` exception. Unfortunately, it doesn't seem to completely solve this problem though, but I suspect that this is due to commits that were overwritten with a `git push --force` or similar.

Summary:
Ref T2683. This is a refinement and simplification of D5257. In particular:
- D5257 only cached the commit chain, not path changes. This meant that we had to go issue an awkward query (which was slow on Facebook's install) periodically while reading the cache. This was reasonable locally but killed performance at FB scale. Instead, we can include path information in the cache. It is very rare that this is large except in Subversion, and we do not need to use this cache in Subversion. In other VCSes, the scale of this data is quite small (a handful of bytes per commit on average).
- D5257 required a large, slow offline computation step. This relies on D9044 to populate parent data so we can build the cache online at will, and let it expire with normal LRU/LFU/whatever semantics. We need this parent data for other reasons anyway.
- D5257 separated graph chunks per-repository. This change assumes we'll be able to pull stuff from APC most of the time and that the cost of switching chunks is not very large, so we can just build one chunk cache across all repositories. This allows the cache to be simpler.
- D5257 needed an offline cache, and used a unique cache structure. Since this one can be built online it can mostly use normal cache code.
- This also supports online appends to the cache.
- Finally, this has a timeout to guarantee a ceiling on the worst case: the worst case is something like a query for a file that has never existed, in a repository which receives exactly 1 commit every time other repositories receive 4095 commits, on a cold cache. If we hit cases like this we can bail after warming the cache up a bit and fall back to asking the VCS for an answer.
This cache isn't perfect, but I believe it will give us substantial gains in the average case. It can often satisfy "average-looking" queries in 4-8ms, and pathological-ish queries in 20ms on my machine; `hg` usually can't even start up in less than 100ms. The major thing that's attractive about this approach is that it does not require anything external or complicated, and will "just work", even producing reasonble improvements for users without APC.
In followups, I'll modify queries to use this cache and see if it holds up in more realistic workloads.
Test Plan:
- Used `bin/repository cache` to examine the behavior of this cache.
- Did some profiling/testing from the web UI using `debug.php`.
- This //appears// to provide a reasonable fast way to issue this query very quickly in the average case, without the various issues that plagued D5257.

Summary:
Ref T4455. This adds a `repository_parents` table which stores `<childCommitID, parentCommitID>` relationships.
For new commits, it is populated when commits are discovered.
For older commits, there's a `bin/repository parents` script to rebuild the data.
Right now, there's no UI suggestion that you should run the script. I haven't come up with a super clean way to do this, and this table will only improve performance for now, so it's not important that we get everyone to run the script right away. I'm just leaving it for the moment, and we can figure out how to tell admins to run it later.
The ultimate goal is to solve T2683, but solving T4455 gets us some stuff anyway (for example, we can serve `diffusion.commitparentsquery` faster out of this cache).
Test Plan:
- Used `bin/repository discover` to discover new commits in Git, SVN and Mercurial repositories.
- Used `bin/repository parents` to rebuild Git and Mercurial repositories (SVN repos just exit with a message).
- Verified that the table appears to be sensible.

Summary:
Ref T4605. Currently, the PullLocal daemon is responsible for two relatively distinct things:
- scheduling repository updates; and
- actually updating repositories.
Move the "actually updating" part into a new `bin/repository update` command, which basically runs the pull, discover, refs and mirror commands. This will let the parent process focus on scheduling in a more understandable way and update multiple repositories at once. It also makes it easier to debug and understand update behavior since the non-scheduling pipeline can be run separately.
Test Plan:
- Ran `update --trace` on SVN, Mercurial and Git repos.
- Ran PullLocal daemon for a while without issues.

Summary:
Ref T4327. I want to make change parsing testable; one thing which is blocking this is that the Git discovery process is still part of `PullLocal` daemon instead of being part of `DiscoveryEngine`. The unit test stuff which I want to use for change parsing relies on `DiscoveryEngine` to discover repositories during unit tests.
The major reason git discovery isn't part of `DiscoveryEngine` is that it relies on the messy "autoclose" logic, which we never implemented for Mercurial. Generally, I don't like how autoclose was implemented: it's complicated and gross and too hard to figure out and extend.
Instead, I want to do something more similar to what we do for pushes, which is cleaner overall. Basically this means remembering the old branch heads from the last time we parsed a repository, and figuring out what's new by comparing the old and new branch heads. This should give us several advantages:
- It should be simpler to understand than the autoclose stuff, which is pretty mind-numbing, at least for me.
- It will let us satisfy branch and tag queries cheaply (from the database) instead of having to go to the repository. We could also satisfy some ref-resolve queries from the database.
- It should be easier to extend to Mercurial.
This implements the basics -- pretty much a table to store the cursors, which we update only for Git for now.
Test Plan:
- Ran migration.
- Ran `bin/repository discover X --trace --verbose` on various repositories with branches and tags, before and after modifying pushes.
- Pushed commits to a git repo.
- Looked at database tables.

Summary:
Ref T4195. To implement the "Author" and "Committer" rules, I need to resolve author/committer strings into Phabricator users.
The code to do this is currently buried in the daemons. Extract it into a standalone query.
I also added `bin/repository lookup-users <commit>` to test this query, both to improve confidence I'm getting this right and to provide a diagnostic command for users, since there's occasionally some confusion over how author/committer strings resolve into valid users.
