172566a769 Aphlict - fix incrementation of _messagesIn
Summary: Ref T7124. The local version of `this` in the handler of 'end' was incremented rather than the global one.

Test Plan: Sending test notifications did not increment the `messages.in` value before this patch even if it should have. With the patch sending test notifications does increment `messages.in`.

a424fec7bb Aphlict - fix getActiveListenerCount return value
Summary: Ref T7126. Dictionaries do not have a `length` property unlike arrays resulting in the `getActiveListenerCount()` function returning undefined results. Using the `length` property on the array of keys will work.

Test Plan: Using `wscat` to generate multiple connections to the server, establish new ones and close others while keeping an eye on the displayed `clients.active` value.

4af1fd2a79 Aphlict - remove listeners when clients close the connection
Summary: Ref T7110. Listeners are now removed when clients close the connection to avoid stacking a never ending number of unused listeners.

Test Plan: Using `wscat` to connect to the Aphlict server; when closing the connection a 'Diconnected.' will appear in the logs and the number of active listeners is decreased by one.

53834d1471 Enable "strict" mode for NodeJS
Summary:
In particular, this changes the behavior of NodeJS in the following ways:

- Any attempt to get or modify the global object will result in an error.
- `null` values of `this` will no longer be evaluated to the global object and primitive values of this will not be converted to wrapper objects.
- Writing or deleting properties which have there writeable or configurable attributes set to false will now throw an error instead of failing silently.
- Adding a property to an object whose extensible attribute is false will also throw an error now.
- A functions arguments are not writeable so attempting to change them will now throw an error `arguments = [...]`.
- `with(){}` statements are gone.
- Use of `eval` is effectively banned.
- `eval` and `arguments` are not allowed as variable or function identifiers in any scope.
- The identifiers `implements`, `interface`, `let`, `package`, `private`, `protected`, `public`, `static` and `yield` are all now reserved for future use (roll on ES6).

Test Plan: Verified that Aphlict was still functional.

4636833f3d Fix module imports in Aphlict server
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'
    at Function.Module._resolveFilename (module.js:338:15)
    at Function.Module._load (module.js:280:25)

2b12f61602 Don't exit from the Aphlict Server prematurely
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.

9e0f70e17d Rewrite Aphlict to use Websockets
Summary:
Fixes T6559. No more flash, use Websockets. This is less aggressive than the earlier version, and retains more server logic.

  - Support "wss".
  - Make the client work.
  - Remove "notification.user" entirely.
  - Seems ok?

Test Plan:
In Safari, Firefox and Chrome, saw the browsers connect. Made a bunch of comments/updates and saw notifications.

Notable holes in the test plan:

  - Haven't tested "wss" yet. I'll do this on secure.
  - Notifications are //too fast// now, locally. I get them after I hit submit but before the page reloads.
  - There are probably some other rough edges, this is a fairly big patch.

Summary:
Ref T5373. The control flow between `aphlict-listener` and `JX.Aphlict` is pretty weird right now, where the listener (which is the highest-level component) has intimate knowledge of how to put the SWF on the page.

  - Make `JX.Aphlict` a real singleton.
  - Instantiate it sooner.
  - Have it handle the flash setup handshake.

84d259cea2 Modify the Aphlict server to transmit messages instead of broadcasting them.
Summary: Ref T4324. Ref T5284. This adds server-side support for keeping track of a set of PHIDs that the Aphlict clients have subscribed to.

ab4324148a Make the Aphlict server more resilient.
Summary:
Currently, the Aphlict server will crash if invalid JSON data is `POST`ed to it. I have fixed this to, instead, return a 400. Also made some minor formatting changes.

Ref T4324. Ref T5284. Also, modify the data structure that is passed around (i.e. `POST`ed to the Aphlict server and broadcast to the Aphlict clients) to include the subscribers. Initially, I figured that we shouldn't expose this information to the clients... however, it is necessary for T4324 that the `AphlictMaster` is able to route a notification to the appropriate clients.

Test Plan:
Making the following `curl` request: `curl --data "{" http://localhost:22281/`.

**Before**
```
sudo ./bin/aphlict debug
Starting Aphlict server in foreground...

    $ 'nodejs' '/usr/src/phabricator/src/applications/aphlict/management/../../../../support/aphlict/server/aphlict_server.js' --port='22280' --admin='22281' --host='localhost' --user='aphlict'

7d255aedba Improve error handling for Aphlict.
Summary: Currently, any error thrown when instantiating an `AphlictMaster` will be assumed to be due to the master already existing. This is a bit overzealous because the [[http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/LocalConnection.html#connect() | documentation]] specifically states than an `ArgumentError` will be throw if "the `LocalConnection` instance is already connected".

Test Plan: Inspected the log message.

fe98aa6839 Publish additional context to the Aphlict server.
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:

3202f0f23d Post data to the Aphlict server in JSON encoded form.
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' }
```

Test Plan: Sent test notifications from `/notification/status/` and verified that the notifications still worked.

a42ec32c98 Modify the Aphlict client to use LocalConnection.
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.
