Future work here should be adding transaction types like `TYPE_BLOG` for when posts are moved between blogs, `TYPE_VISIBILITY` for when posts are moved to published, etc. Nothing too tricky there but keeping this diff relatively small seems prudent.

Summary:
Ref T7149. This isn't complete and isn't active yet, but does basically work. I'll shore it up in the next few diffs.
The new workflow goes like this:
> Client, file.allocate(): I'd like to upload a file with length L, metadata M, and hash H.
Then the server returns `upload` (a boolean) and `filePHID` (a PHID). These mean:
| upload | filePHID | means |
|---|---|---|
| false | false | Server can't accept file.
| false | true | File data already known, file created from hash.
| true | false | Just upload normally.
| true | true | Query chunks to start or resume a chunked upload.
All but the last case are uninteresting and work like exising uploads with `file.uploadhash` (which we can eventually deprecate).
In the last case:
> Client, file.querychunks(): Give me a list of chunks that I should upload.
This returns all the chunks for the file. Chunks have a start byte, an end byte, and a "complete" flag to indicate that the server already has the data.
Then, the client fills in chunks by sending them:
> Client, file.uploadchunk(): Here is the data for one chunk.
This stuff doesn't work yet or has some caveats:
- I haven't tested resume much.
- Files need an "isPartial()" flag for partial uploads, and the UI needs to respect it.
- The JS client needs to become chunk-aware.
- Chunk size is set crazy low to make testing easier.
- Some debugging flags that I'll remove soon-ish.
- Downloading works, but still streams the whole file into memory.
- This storage engine is disabled by default (hardcoded as a unit test engine) because it's still sketchy.
- Need some code to remove the "isParital" flag when the last chunk is uploaded.
- Maybe do checksumming on chunks.
Test Plan:
- Hacked up `arc upload` (see next diff) to be chunk-aware and uploaded a readme in 18 32-byte chunks. Then downloaded it. Got the same file back that I uploaded.
- File UI now shows some basic chunk info for chunked files:

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.

There's no UI to create these yet, so users can't actually get invites (and administrators can't send them).
This stuff is a complicated mess because there are so many interactions between accounts, email addresses, email verification, email primary-ness, and user verification. However, I think I got it right and got test coverage everwhere.
The degree to which this is exception-driven is a little icky, but I think it's a reasonable way to get the testability we want while still making it hard for callers to get the flow wrong. In particular, I expect there to be at least two callers (one invite flow in the upstream, and one derived invite flow in Instances) so I believe there is merit in burying as much of this logic inside the Engine as is reasonably possible.

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.

Summary:
Ref T3165. Builds a dedicated index for Conpherence to avoid scale/policy filtering concerns.
- This is pretty one-off but I think it's generally OK.
- There's no UI for it.
- `ConpherenceFulltextQuery` is very low-level. You would need to do another query on the PHIDs it returns to actually show anything to the user.
- The `previousTransactionPHID` is so you can load chat context efficiently. Specifically, if you want to show results like this:
> previous line of context
> **line of chat that matches the query**
> next line of context
...you can read the previous lines out of `previousTransactionPHID` directly, and the next lines by issuing one query with `WHERE previousTransactionPHID IN (...)`.
I'm not 100% sure this is useful, but it seemed like a reasonable thing to provide, since there's no way to query this efficiently otherwise and I figure a lot of chat might make way more sense with a couple of lines of context.
Test Plan:
- Indexed a thread manually (whole thing indexed).
- Indexed a thread by updating it (just the new comment indexed).
- Wrote a hacky test script and got reasonable-looking query results.
