Summary:
This was broken in D11383. Basically, I had the `ws` module installed globally whilst testing, but the changes made do not work if the `ws` module is installed locally (i.e. in the `./support/aphlict/server/node_modules` directory). After poking around, it seems that this is due to the sandboxing that is done by `JX.require`.
A quick fix is to just //not// use `JX.require`, although you may have a better idea?
The error that is occurring is as follows:
```

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 T6713. This isn't very clean, and primarily unblocks D11143.
After D11143, I have a reliable local race where I submit, get a notification immediately, then get a double update (form submission + notification-triggered update).
Instead, make the notification updates wait for form submissions.
This doesn't resolve the race completely. The notification updates don't block chat submission (only the other way around), so if you're really fast you can submit at the same time someone else sends chat and race. But this fixes the most glaring issue.
The overall structure here is still pretty shaky but I tried to improve things a little, at least.
Test Plan: Chatted with myself, saw 0 races instead of 100% races.

Ref T6559. Adds a "JX.Leader" primitive to replace the synchronization over Flash. This does a couple of things:
- Offers an "onBecomeLeader" event, which we can use to open the WebSocket.
- Offers an "onReceiveMessage" event, which we can use to dispatch notifications and handle requests to play sounds and send desktop notifications.
- Offers a "broadcast()" method, which we can use to send desktop notification and sound requests.
Test Plan:
Added some code like this:
```
if (!statics.leader) {
statics.leader = true;
JX.Leader.listen('onBecomeLeader', function() {
JX.log("This tab is now the leader.");
});
JX.Leader.listen('onReceiveBroadcast', function(message, is_leader) {
JX.log('[' + (is_leader ? 'As Leader' : 'Not Leader') + '] ' + message);
});
JX.Leader.start();
}
```
Then:
- Saw first tab open become leader reliably in Safari, Chrome, Firefox.
- Saw new tab become leader reliably when the first tab was closed.
- Saw broadcast() work as documented and deliver messages with correct leadership-flag and uniqueness.

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.

Fixes T6692. Addresses two main issues:
- The write guard would sometimes not get disposed of on exception pathways, generating an unnecessary secondary error which was just a symptom of the original root error.
- This was generally confusing and reduced the quality of reports we received because users would report the symptomatic error sometimes instead of the real error.
- Instead, reflow the handling so that we always dispose of the write guard if we create one.
- If we missed the Controller-level error page generation (normally, a nice page with full CSS, etc), we'd jump straight to Startup-level error page generation (very basic plain text).
- A large class of errors occur too early or too late to be handled by Controller-level pages, but many of these errors are not fundamental, and the plain text page is excessively severe.
- Provide a mid-level simple HTML error page for errors which can't get full CSS, but also aren't so fundamental that we have no recourse but plain text.
Test Plan:
Mid-level errors now produce an intentional-looking error page:
