Summary:
Fixes T12087. When transitioning into a clustered configuration for the first time, the documentation recommends using a one-device cluster as a transitional step.
However, installs may not do this for whatever reason, and we aren't as clear as we could be in warning about clusterizing directly into a multi-device cluster.
Roughly, when you do this, we end up believing that working copies exist on several different devices, but have no information about which copy or copies are up to date. //Usually// they all were already synchronized and are all up to date, but we can't make this assumption safely without risking data.
Instead, we err on the side of caution, and require a human to tell us which copy we should consider to be up-to-date, using `bin/repository thaw --promote`.
Test Plan:
```
$ ./bin/repository clusterize rLOCKS --service repos001.phacility.net
Service "repos001.phacility.net" is actively bound to more than one device
(local002.local, local001.phacility.net).
If you clusterize a repository onto this service it will be unclear which
devices have up-to-date copies of the repository. This leader/follower
ambiguity will freeze the repository. You may need to manually promote a
device to unfreeze it. See "Ambiguous Leaders" in the documentation for
discussion.
Continue anyway? [y/N]

Fixes T11309. When checking if a repository was fully imported, we incorrectly allow unreachable, un-imported commits to prevent the repository from moving to "Imported".
This can happen if you delete branches from a repository while it is importing.
Instead, ignore unreachable commits when checking for remaining imports, and when reporting status via `bin/repository importing`.
Test Plan:
- Stopped daemons.
- Created a new repository and activated it.
- Ran `bin/repository update Rxx`.
- Deleted a branch in the repository.
- Ran `bin/repository update Rxx`.

Summary:
Ref T4292. Currently, we hold one big lock around the whole `bin/repository update` workflow.
When running multiple daemons on different hosts, this lock can end up being contentious. In particular, we'll hold it during `git fetch` on every host globally, even though it's only useful to hold it locally per-device (that is, it's fine/good/expected if `repo001` and `repo002` happen to be fetching from a repository they are observing at the same time).
Instead, split it into two locks:
- One lock is scoped to the current device, and held during pull (usually `git fetch`). This just keeps multiple daemons accidentally running on the same host from making a mess when trying to initialize or update a working copy.
- One lock is scoped globally, and held during discovery. This makes sure daemons on different hosts don't step on each other when updating the database.
If we fail to acquire either lock, assume some other process is legitimately doing the work and bail more quietly instead of fataling. In approximately 100% of cases where users have hit this lock contention, that was the case: some other daemon was running somewhere doing the work and the error didn't actually represent an issue.
If there's an actual problem, we still raise a diagnostically useful message if you run `bin/repository update` manually, so there are still tools to figure out that something is hung or whatever.
Test Plan:
- Ran `bin/repository update`, `pull`, `discover`.
- Added `sleep(5)`, forced processes to contend, got lock exceptions and graceful exit with diagnostic message.

Summary:
Fixes T10940. Two issues currently:
First, `PullLocal` deamon refuses to update non-cluster repositories on cluster devices. However, this is surprising/confusing/bad because as soon as you enroll a repository host in the cluster, most of the repositories on it stop working until you `clusterize` them. This is especially confusing because the documentation gives you a very nice, gradual walkthrough about going through things slowly and being able to check your work at every step, but we really drop you off a bit of a cliff here. The workflow implied by the documentation is a desirable one.
This operation is generally only unsafe/problematic if the daemon would be creating a //new// working copy. If a working copy already exists, we can reasonably guess that it's almost certainly because you've enrolled a previously un-clustered host into a new cluster. This allows the nice, gradual workflow the documentation describes to proceed as expected, without any weird surprises.
Instead of refusing to update these repositories, only refuse to update them if updating would create a new working copy. This should make transitioning much smoother without any meaningful reduction in safety.
Second, the lower-level `bin/repository update`, `refs`, `mirror`, etc., commands don't apply this same check. However, these commands are potentially just as dangerous. Use the same code to do a similar check there, making sure we only operate on repositories that are either expected to be on the current device, or which already exist here.
Test Plan:
- Ran `bin/phd debug pull`, saw diagnostic information choose to update most repositories (including some non-cluster repositories) but properly skip non-cluster repositories that do not exist locally.
- Ran `bin/repository update`, etc., saw the command apply consistent rules to the rules applied by `PullLocal` and refuse to update non-local repositories it would need to create.

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.

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.

(This makes it easier to discover repositories in unit tests in the future, since we don't need to build a PullLocal daemon and can just build a DiscoveryEngine.)
Test Plan: Ran `phd debug pulllocal`. Ran `repostory discover`.

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 T2015. Not directly related to Drydock, but I've wanted to do this for a bit.
Introduce a common base class for all the workflows in the scripts in `bin/*`. This slightly reduces code duplication by moving `isExecutable()` to the base, but also provides `getViewer()`. This is a little nicer than `PhabricatorUser::getOmnipotentUser()` and gives us a layer of indirection if we ever want to introduce more general viewer mechanisms in scripts.
Test Plan: Lint; ran some of the scripts.

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.
Test Plan:
I tested this using `bin/repository lookup-users` and `reparse.php --message` on Git, Mercurial and SVN commits. Here's the `lookup-users` output:
>>> orbital ~/devtools/phabricator $ ./bin/repository lookup-users rINIS3
Examining commit rINIS3...
Raw author string: epriestley
Phabricator user: epriestley (Evan Priestley )
Raw committer string: null
>>> orbital ~/devtools/phabricator $ ./bin/repository lookup-users rPOEMS165b6c54f487c8
Examining commit rPOEMS165b6c54f487...
Raw author string: epriestley <git@epriestley.com>
Phabricator user: epriestley (Evan Priestley )
Raw committer string: epriestley <git@epriestley.com>
Phabricator user: epriestley (Evan Priestley )
>>> orbital ~/devtools/phabricator $ ./bin/repository lookup-users rINIH6d24c1aee7741e
Examining commit rINIH6d24c1aee774...
Raw author string: epriestley <hg@yghe.net>
Phabricator user: epriestley (Evan Priestley )
Raw committer string: null
>>> orbital ~/devtools/phabricator $
The `reparse.php` output was similar, and all VCSes resolved authors correctly.

Summary:
Ref T4039. This is mostly to deal with that, to prevent the security issues associated with mutable local paths. The next diff will lock them in the web UI.
I also added a confirmation prompt to `bin/repository delete`, which was a little scary without one.
See one comment inline about the `--as` flag. I don't love this, but when I started adding all the stuff we'd need to let this transaction show up as "Administrator" it quickly got pretty big.
Test Plan: Ran `bin/repository edit ...`, saw an edit with a transaction show up on the web UI.

Summary: Ref T4068. Adds a command to list all commits in an "importing" status. This will allow users to use `reparse.php` to diagnose and repair issues.
Test Plan:
- Ran `bin/repository importing P`, etc.
- Used `reparse.php` to reparse some commit stages and saw status update correctly.
- Ran on a repo with no importing commits.
- Ran with `... --simple | xargs`, which saves us having to put an `awk` or something in there for users.

Summary:
Ref T4068. In some cases like that one, I anticipate a repository not fully importing when a handful of random commits are broken. In the long run we should just deal with that properly, but in the meantime provide an administrative escape hatch so you can mark the repository as imported and get it running normally.
The major reason to do this is that Herald, Feed, Harbormaster, etc., won't activate until a repository is "imported".
Test Plan:
- Tried to mark an imported repository as imported, got an "already imported" message.
- Same for not-imported.
- Marked a repository not-imported.
- Marked a repository imported.
- Marked a repository not-imported, then waited for the daemons to mark it imported again automatically.
