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:
```
<<< UNCAUGHT EXCEPTION! >>>
Error: Cannot find module 'ws'

Summary: By calling `process.exit(1)` we are forcing the Node.js process to exit prematurely. Specifically, the process is terminated before the error is written to the log file. This can be verified by inspecting the value of `debug._logs[0]._writableState.writing` immediately before the process is terminated.
Test Plan: Ran `./bin/aphlict debug` without the `ws` module being installed. Verified that `<<< UNCAUGHT EXCEPTION! >>>` was echoed to the console as well as the log file. Also verified that the exit status was non-zero.

Summary:
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:
{F259885}
Verified that setup errors still render properly.
@chad, feel free to tweak the exception page -- I just did a rough pass on it. Like the setup error stuff, it doesn't have Celerity, so we can't use `{$colors}` and no other CSS will be loaded.

Summary:
Fixes T6044. We've had two cases (both the same install, coincidentally) where pages got hung doing too much data fetching.
When pages hang, we don't get a useful stack trace out of them, since nginx, php-fpm, or PHP eventually terminates things in a non-useful way without any diagnostic information.
The second time (the recent Macros issue) I was able to walk the install through removing limits on nginx, php-fpm, php, and eventually getting a profile by letting the page run for several minutes until the request completed. However, this install is exceptionally technically proficient and this was still a big pain for everyone, and this approach would not have worked if the page actually looped rather than just taking a long time.
Provide `debug.time-limit`, which should give us a better tool for reacting to this situation: by setting it to a small value (like 10), we'll kill the page after 10 seconds with a trace, before nginx/php-fpm/php/etc can kill it uselessly. Hopefully that will be enough information to find the issue (generally, getting a trace has been 95% of the problem in the two cases we've encountered).
Test Plan: Set this option to `3` and added a sleep loop, saw a termination after 3 seconds with a useful trace.

Summary:
Ref T4324. As well as sending the key for the notification, also publish the notification type and a list of subscribers to the Aphlict server.
The idea here is that the Aphlict server passes anything within the `data` key to the clients, whereas other keys (such as `subscribers`) will be used by the server to determine where the notifications should be routed.
Note that these changes don't do anything useful, but are a prerequisite for further work on T4324.
Test Plan:
Sent myself test notifications at `/notification/status/`. Also inspected the Aphlict server debug output:
```
> sudo ./bin/aphlict --foreground
Starting server in foreground, ignoring pidfile...
Launching server:
$ node '/usr/src/phabricator/support/aphlict/server/aphlict_server.js' --port='22280' --admin='22281' --host='localhost' --user='aphlict' --log='/var/log/aphlict.log'

Summary:
Ref T4324. Currently, notifications data is `POST`ed to the Aphlict server in the `application/x-www-form-urlencoded` format. This works fine for simple data but is problematic for nested data. For example:
```lang=php
array(
'data' => array(
'key' => '6021329908492455737',
'type' => 'PhabricatorNotificationAdHocFeedStory',
),
'subscribers' => array(
'PHID-USER-y7ofqm276ejs62yqghge',
),
);
```
Is encoded as `data%5Bkey%5D=6021329908492455737&data%5Btype%5D=PhabricatorNotificationAdHocFeedStory&subscribers%5B0%5D=PHID-USER-y7ofqm276ejs62yqghge`. This string is then (incorrectly) decoded by `querystring.parse` as:
```lang=javascript
> querystring.parse('data%5Bkey%5D=6021329908492455737&data%5Btype%5D=PhabricatorNotificationAdHocFeedStory&subscribers%5B0%5D=PHID-USER-y7ofqm276ejs62yqghge');
{ 'data[key]': '6021329908492455737',
'data[type]': 'PhabricatorNotificationAdHocFeedStory',
'subscribers[0]': 'PHID-USER-y7ofqm276ejs62yqghge' }
```

Summary:
Ref T4324. Currently, an Aphlict client (with a corresponding connection to the Aphlict Server) is created for every tab that a user has open. This significantly affects the scalability of Aphlict as a service. Instead, we can use `LocalConnection` instances to coordinate the communication of multiple Aphlict clients to the server.
Similar functionality existed prior to D2704, but was removed as the author was not able to get this functionality working as intended. It seems that the main issue with the initial attempt was the use of the `setTimeout` function, which seemed to be a blocking call which prevented messages from being received. I have instead used an event-based model using a `Timer` object.
Roughly this works as follows:
# The first instance will create an `AphlictClient` and an `AphlictMaster`. The `AphlictClient` will register itself with the `AphlictMaster` and will consequently be notified of incoming messages.
# The `AphlictClient` is then responsible for pinging the `AphlictMaster` at regular intervals. If the client does not ping the master in a given period of time, the master will assume that the client is dead and will remove the client from the pool.
# Similarly, the `AphlictMaster` is required to respond to pings with a "pong" response. The pong response lets the clients know that the `AphlictMaster` is still alive. If the clients do not receive a pong in a given period of time, then the clients will attempt to spawn a new master.
Test Plan: I have tested this on our Phabricator install with a few tabs opened and inspecting the console output. I will upload a screencast of my test results.

Fixes T3923. On `secure.phabricator.com`, we occasionally get slowed to a crawl when someone runs a security scanner against us, or 5 search bots decide to simultaneously index every line of every file in Diffusion.
Every time a user makes a request, give their IP address some points. If they get too many points in 5 minutes, start blocking their requests automatically for a while.
We give fewer points for logged in requests. We could futher refine this (more points for a 404, more points for a really slow page, etc.) but let's start simply.
Also, provide a mechanism for configuring this, and configuring the LB environment stuff at the same time (this comes up rarely, but we don't have a good answer right now).

This is purely a prototype at the moment, but the basic functionality sort of
works.
I'm not sure how far I want to go with this but I think we might be able to get
somewhere without it being gross.
The idea here is to build a notification server WITHOUT using Comet, since Comet
is extremely difficult and complicated.
Instead, I use Flash on the client. LocalConnection allows flash instances to
talk to each other and connect() can be used as a locking primitive. This allows
all the instances to elect a master instance in a race-safe way. The master is
responsible for opening a single connnection to the server.
On the server, I use Node.js since PHP is pretty unsuitable for this task.
See Github Issue #3: https://github.com/facebook/phabricator/issues/3
One thing I need to figure out next is if I can reasonably do SSL/TSL over Flash
(it looks like I can, in theory, with the as3crypto library) or if the server
needs to just send down version information and trigger a separate Ajax call on
the client.
Test Plan:
Created a client pool and connected it to the server, with election and failover
apparently working correctly.
