29fd3f136b Allow columns to be marked as nonmutable (so save() will not change them)
Summary:
Ref T6840. This feels a little dirty; open to alternate suggestions.

We currently have a race condition where multiple daemons may load a commit and then save it at the same time, when processing "reverts X" text. Prior to this feature, two daemons would never load a commit at the same time.

The "reverts X" load/save has no effect (doesn't change any object properties), but it will set the state back to the loaded state on save(). This overwrites any flag updates made to the commit in the meantime, and can produce the race in T6840.

In other cases (triggers, harbormaster, repositories) we deal with this kind of problem with "append-only-updates + single-consumer", or a bunch of locking. There isn't really a good place to add a single consumer for commits, since a lot of daemons need to access them. We could move the flags column to a separate table, but this feels pretty complicated. And locking is messy, also mostly because we have so many consumers.

Just exempting this column (which has unusual behavior) from `save()` feels OK-ish? I don't know if we'll have other use cases for this, and I like it even less if we never do, but this patch is pretty small and feels fairly understandable (that said, I also don't like that it can make some properties just silently not update if you aren't on the lookout).

So, this is //a// fix, and feels simplest/least-bad for the moment to me, I thiiink.

Test Plan: Added and executed unit tests.

2cd77b5b58 Improve taskmaster behavior on empty queues
Summary:
Right now, taskmasters on empty queues sleep for 30 seconds. With a default setup (4 taskmasters), this averages out to 7.5 seconds between the time you do anything that queues something and the time that the taskmasters start work on it.

On instances, which currently launch a smaller number of taskmasters, this wait is even longer.

Instead, sleep for the number of seconds that there are taskmasters, with a random offset. This makes the average wait to start a task from an empty queue 1 second, and the average maximum load of an empty queue also one query per second.

On loaded instances this doesn't matter, but this should dramatically improve behavior for less-loaded instances without any real tradeoffs.

Test Plan: Started several taskmasters, saw them jitter out of sync and then use short sleeps to give an empty queue about a 1s delay.

Summary:
Ref T7152. Ref T1139. This updates Phabricator so third-party libraries can translate their own stuff. Also:

  - Hide "All Caps" when not in development mode, since some users have found this a little confusing.
  - With other changes, adds a "Raw Strings" mode (development mode only).
  - Add an example silly translation to make sure the serious business flag works.
  - Add a basic British English translation.
  - Simplify handling of translation overrides.

Test Plan:
  - Flipped serious business / development on and off and saw silly/development translations drop off.
  - Switched to "All Caps" and saw all caps.
  - Switched to Very English, Wow!
  - Switched to British english and saw "colour".

9b359affe7 Prepare SSH connections for proxying
Summary:
Ref T7034.

In a cluster environment, when a user connects with a VCS request over SSH (like `git pull`), the receiving server may need to proxy it to a server which can actually satisfy the request.

In order to proxy the request, we need to know which repository the user is interested in accessing.

Split the SSH workflow into two steps:

  # First, identify the repository.
  # Then, execute the operation.

In the future, this will allow us to put a possible "proxy the whole thing somewhere else" step in the middle, mirroring the behavior of Conduit.

This is trivially easy in `git` and `hg`. Both identify the repository on the commmand line.

This is fiendishly complex in `svn`, for the same reasons that hosting SVN was hard in the first place. Specifically:

  - The client doesn't tell us what it's after.
  - To get it to tell us, we have to send it a server capabilities string //first//.
  - We can't just start an `svnserve` process and read the repository out after a little while, because we may need to proxy the request once we figure out the repository.
  - We can't consume the client protocol frame that tells us what the client wants, because when we start the real server request it won't know what the client is after if it never receives that frame.
  - On the other hand, we must consume the second copy of the server protocol frame that would be sent to the client, or they'll get two "HELLO" messages and not know what to do.

The approach here is straightforward, but the implementation is not trivial. Roughly:

  - Start `svnserve`, read the "hello" frame from it.
  - Kill `svnserve`.
  - Send the "hello" to the client.
  - Wait for the client to send us "I want repository X".
  - Save the message it sent us in the "peekBuffer".
  - Return "this is a request for repository X", so we can proxy it.

Then, to continue the request:

  - Start the real `svnserve`.
  - Read the "hello" frame from it and throw it away.
  - Write the data in the "peekBuffer" to it, as though we'd just received it from the client.
  - State of the world is normal again, so we can continue.

Also fixed some other issues:

  - SVN could choke if `repository.default-local-path` contained extra slashes.
  - PHP might emit some complaints when executing the commit hook; silence those.

Test Plan: Pushed and pulled repositories in SVN, Mercurial and Git.

d8550c114d Promote instance identity to the upstream and pass it to commit hooks
Summary:
Fixes T7019. In a cluster environment, pushes currently fail because the commit hook can't identify the instance.

For web processes, the hostname identifies the instance -- but we don't have a hostname in the hook.

For CLI processes, the environment identifies the instance -- but we don't have an environment in the hook under SVN.

Promote the instance identifier into the upstream and pack/unpack it explicitly for hooks. This is probably not useful for anyone but us, but the amount of special-purpose code we're introducing is very small.

I poked at trying to do this in a more general way, but:

  - We MUST know this BEFORE we run code, so the normal subclassing stuff is useless.
  - I couldn't come up with any other parameter which might ever be useful to pass in.

19be32656f Implement clock/trigger infrastructure for scheduling actions
Summary:
Ref T6881. Hopefully, this is the hard part.

This adds a new daemon (the "trigger" daemon) which processes triggers, schedules them, and then executes them at the scheduled time. The design is a little complicated, but has these goals:

  - High resistance to race conditions: only the application writes to the trigger table; only the daemon writes to the event table. We won't lose events if someone saves a meeting at the same time as we're sending a reminder out for it.
  - Execution guarantees: scheduled events are guaranteed to execute exactly once.
  - Support for arbitrarily large queues: the daemon will make progress even if there are millions of triggers in queue. The cost to update the queue is proportional to the number of changes in it; the cost to process the queue is proportional to the number of events to execute.
  - Relatively good observability: you can monitor the state of the trigger queue reasonably well from the web UI.
  - Modular Infrastructure: this is a very low-level construct that Calendar, Phortune, etc., should be able to build on top of.

It doesn't have this stuff yet:

  - Not very robust to bad actions: a misbehaving trigger can stop the queue fairly easily. This is OK for now since we aren't planning to make it part of any other applications for a while. We do still get execute-exaclty-once, but it might not happen for a long time (until someone goes and fixes the queue), when we could theoretically continue executing other events.
  - Doesn't start automatically: normal users don't need to run this thing yet so I'm not starting it by default.
  - Not super well tested: I've vetted the basics but haven't run real workloads through this yet.
  - No sophisticated tooling: I added some basic stuff but it's missing some pieces we'll have to build sooner or later, e.g. `bin/trigger cancel` or whatever.
  - Intentionally not realtime: This design puts execution guarantees far above realtime concerns, and will not give you precise event execution at 1-second resolution. I think this is the correct goal to pursue architecturally, and certainly correct for subscriptions and meeting reminders. Events which execute after they have become irrelevant can simply decline to do anything (like a meeting reminder which executes after the meeting is over).

In general, the expectation for applications is:

  - When creating an object (like a calendar event) that needs to trigger a scheduled action, write a trigger (and save the PHID if you plan to update it later).
  - The daemon will process the event and schedule the action efficiently, in a race-free way.
  - If you want to move the action, update the trigger and the daemon will take care of it.
  - Your action will eventually dump a task into the task queue, and the task daemons will actually perform it.

Test Plan:
Using a test script like this:

```
<?php

require_once 'scripts/__init_script__.php';

$trigger = id(new PhabricatorWorkerTrigger())
  ->setAction(
    new PhabricatorLogTriggerAction(
      array(
        'message' => 'test',
      )))
  ->setClock(
    new PhabricatorMetronomicTriggerClock(
      array(
        'period' => 33,
      )))
  ->save();

var_dump($trigger);
```

...I queued triggers and ran the daemon:

  - Verified triggers fire;
  - verified triggers reschedule;
  - verified trigger events show up in the web UI;
  - tried different periods;
  - added some triggers while the daemon was running;
  - examined `phd debug` output for anything suspicious.

It seems to work in trivial use case, at least.

66975fa51b Implement "trigger clocks" for scheduling events
Summary:
Ref T6881. This will probably make more sense in a couple of diffs, but this is a class that implements scheduling/recurrence rules. Two rules are provided:

  - Trigger an event at a specific time (e.g., a meeting reminder notification).
  - Trigger an event on the Nth day of every month (e.g., a subscription bill).

At some point, we'll presumably add a rule for T2896 (maybe using the "RRULE" spec) so you can do stuff like "the second to last thursday of every month", etc., but we don't need that for now.

(The "Nth day of every month, or move it back if no such day exists" rule doesn't seem to be expressible with the "RRULE" format, so implementing that wouldn't give us a superset of this. I think this rule is correct and desirable for this purpose, though.)

Test Plan: Added and executed unit tests.

b9788fed00 Recover more cleanly from worker tasks with unconstructable classes
Summary:
This is unusual, but if `getWorkerInstance()` throws we end up with an undefined `$worker` when recovering from the exception.

Instead, handle this case slightly more gracefully.

The easiest way to hit this is to schedule a task for a worker that doesn't exist (or remove an existing worker, which is what I did to hit it).

Test Plan: Saw a more graceful error recovery; ran some normal successful tasks out of the queue.

923096efc8 Config - add phd.variant-config to suppress "Daemon & Web config" error message on a per key basis
Summary: Fixes T6959.

Test Plan: When I was ready to test the feature, the "Daemon & Web config" error already showed up, from having added phd.variant-config. I went meta and changed the value of phd.variant-config to have phd.variant-config. The config error disappeared. I then changed the conpherence setting about conpherence email prefix and the error showed up again. Removing the conpherence config setting made the error disappear once more.

Summary:
Ref T6881. This is part 1 of my 35-step plan to support subscriptions that bill monthly.

Expanding the capabilities of counters will let me use them to create a logical clock on time-based event updates, build a daemon on top of that, and eventually get time-based triggers.

b1a5d5a815 Stop purging caches in bin/storage adjust
Summary:
Fixes T6548.

  - This workflow doesn't work under reasonable configurations and isn't trivial to fix (see T6548).
  - We don't need it; this just makes things a little bit faster if you have to migrate everything (e.g., immediately after T1191) and the installs we know about have generally upgraded by now.
  - This keeps kicking PKCS8 keys out of cache which is a pain.

Test Plan: Ran `bin/storage adjust` without it doing an implicit cache purge.
