Summary:
Depends on D19816. Ref T13216. See PHI908. See PHI750. In a few cases, users have pushed multi-gigabyte files full of various things that probably shouldn't be version controlled. This tends to create various headaches.
Add support for limiting the maximum size of any object. Specifically, we:
- list all the objects each commit touches;
- check their size after the commit applies;
- if it's over the limit, reject the commit.
This change doesn't actually hook the limit up (the limit is always "0", i.e. unlimited), and doesn't have Mercurial or SVN support. The actual parser bit would probably be better in some other `Query/Parser` class eventually, too. But it at least roughly works.
Test Plan:
Changed the hard-coded limit to other values, tried to push stuff, got sensible results:
```
$ echo pew >> magic_missile.txt && git commit -am pew && git push

Summary:
Depends on D19814. Ref T13216. See PHI885. For various eldritch reasons, `git fetch` can hang. Although we'd probably like to fix this with `git fetch --require-sustained-network-transfer-rate=512KB/5s` or similar, that flag doesn't exist and we don't have a reasonable way to build it.
Short of that, move toward formalizing a repository "copy time limit": the longest amount of time anything may spend trying to make a copy of this repository.
This grows out of the existing intracluster sync limit, which is effectively the same thing. Here, apply it to `git clone` and `git fetch` in Drydock working copy construction, too. A future change may make it configurable.
Test Plan:
- Set the limit to 0.001.
- Tried to build and lease working copies, got sensible timeout errors (see D19815).
```

Summary:
Ref T13216. See PHI943. If autoscale lightning strikes all your servers at once and destroys them, the path to recovery can be unclear. You're "supposed" to:
- demote all the devices;
- disable the bindings;
- bind the new servers;
- put whatever working copies you can scrape up back on disk;
- promote one of the new servers.
However, the documentation is a bit misleading (it was sort of written with "you lost one or two devices" in mind, not "you lost every device") and demote-before-disable is unnecessary and slightly risky if servers come back online. There's also a missing guardrail before the promote step which lets you accidentally skip the demotion step and end up in a confusing state. Instead:
- Add a guard rail: when you try to promote a new server, warn if inactive devices still have versions and tell the user to demote them.
- Allow demotion of inactive devices: the order "disable, demote" is safer and more intuitive than "demote, disable" and there's no reason to require the unintuitive order.
- Make the "cluster already has leaders" message more clear.
- Make the documentation more clear.
Test Plan:
- Bound a repository to two devices.
- Wrote to A to make it a leader, then disabled it (simulating a lightning strike).
- Tried to promote B. Got a new, useful error ("demote A first").
- Demoted A (before: error about demoting inactive devices; now: works fine).
- Promoted B. This worked.

Summary:
Depends on D19779. Ref T13216. The push logs currently record the "hostWait", which is roughly "locking + subprocess cost". We also record locking separately, so we can figure out "subprocess cost" alone by subtracting the lock costs.
However, the subprocess (normally `git receive-pack`) runs hooks, and we don't have an easy way to figure out how much time was spent doing actual `git` stuff vs spent doing commit hook processing. This would have been useful in diagnosing at least one recent issue.
Track at least a rough hook cost and record it in the push logs.
Test Plan: Pushed to a repository, saw a reasonable hook cost appear in the database table.

Summary:
Depends on D19778. Ref T13216. See PHI943, PHI889, et al.
We currently have a push log and a pull log, but do not separately log intracluster synchronization events. We've encountered several specific cases where having this kind of log would be helpful:
- In PHI943, an install was accidentally aborting locks early. Having timing information in the sync log would let us identify this more quickly.
- In PHI889, an install hit an issue with `MaxStartups` configuration in `sshd`. A log would let us identify when this is an issue.
- In PHI889, I floated a "push the linux kernel + fetch timeout" theory. A sync log would let us see sync/fetch timeouts to confirm this being a problem in practice.
- A sync log will help us assess, develop, test, and monitor intracluster routing sync changes (likely those in T13211) in the future.
Some of these events are present in the pull log already, but only if they make it as far as running a `git upload-pack` subprocess (not the case with `MaxStartups` problems) -- and they can't record end-to-end timing.
No UI yet, I'll add that in a future change.
Test Plan:
- Forced all operations to synchronize by adding `|| true` to the version check.
- Pulled, got a sync log in the database.

Summary:
Ref T13109. Ref T13202. See PHI905. See PHI889. When we receive a write to a repository cluster, we currently send it to a random writable node.
Instead, we can prefer:
- the node currently holding the write lock; or
- any node which is already up to date.
These should simply be better nodes to take writes in all cases. The write lock is global for the repository, so there's no scaling benefit to spreading writes across different nodes, and these particular nodes will be able to accept the write more quickly.
Test Plan:
- This is observable by using `fprintf(STDERR, "%s\n", ...)` in the logic, then running `git push`. I'd like to pull this routing logic out of `PhabricatorRepository` at some point, probably into a dedicated `ClusterURIQuery` sort of class, but that is a larger change.
- Added some `fprintf(...)` stuff around which nodes were being selected.
- Added a `sleep(10)` after grabbing the write lock.
- In one window, pushed. Then pushed in a second window.
- Saw the second window select the lock holder as the write target based on it currently holding the lock.
- Without a concurrent push, saw pushes select up-to-date nodes based on their up-to-date-ness.

Summary:
Ref T13110. Currently, build status is published the same way for every Buildable by the BuildEngine.
I want to change this to delegate publishing to each Buildable, particularly so that Differential may use more detailed rules for handling builds and drafts.
Rather than add additional methods to the existing `BuildableInterface`, add an engine generator method instead. This is a pattern which has seen more use recently (e.g., in Ferret) and lets us pay a little more upfront to pull complex pieces of logic out of the main class and let them use inheritence more easily. If we had Traits that might cover this to some degree.
I'd expect to eventually reduce the size of `BuildableInterface` and move the `CircleCI` and `BuildKite` interfaces so that the `BuildableEngine` implements them instead of the main object.
Here, this new engine does nothing and is never instantiated. In upcoming changes, publishing logic will move into it so that Differential can handle publishing differently.
Test Plan: Ran `arc liberate`, loaded pages, grepped for `BuildableInterface`.

Summary:
Ref T13114. See PHI514. This makes some attempt to undo the damage caused by incorrectly publishing a repository.
Don't run this.
Test Plan: Yikes.

Summary:
Depends on D19249. Ref T13109. Add timing information to the `PushEvent`:
- `writeWait`: Time spent waiting for a write lock.
- `readWait`: Time spent waiting for a read lock.
- `hostWait`: Roughly, total time spent on the leaf node.
The primary goal here is to see if `readWait` is meaningful in the wild. If it is, that motivates smarter routing, and the value of smarter routing can be demonstrated by looking for a reduction in read wait times.
Test Plan: Pushed some stuff, saw reasonable timing values in the table. Saw timing information in "Export Data".

Summary:
Depends on D19247. Ref T13109. When we receive an SSH request, generate a random unique ID for the request. Then thread it down through the process tree.
The immediate goal is to let the `ssh-exec` process coordinate with `commit-hook` process and log information about read and write lock wait times. Today, there's no way for `ssh-exec` to interact with the `PushEvent`, but this is the most helpful place to store this data for users.
Test Plan: Made pushes, saw the `PushEvent` table populate with a random request ID. Exported data and saw the ID preserved in the export.

Summary:
Ref T13109. Make it slightly more clear what the scope of the write and read locks are, and slightly more clear that we're actively acquiring locks, not just sitting around waiting.
While waiting on another writer, show who we're waiting on so you can walk over to their desk and glare at them.
Test Plan:
Added `sleep(15)` after `willWrite()`. Pushed in two windows. Saw new, more informative messages. In the second window, saw the new guidance:
> # Waiting for hector to finish writing (on device "repo1.local.phacility.net" for 11s)...
