a15444aa79 Remove PhabricatorStartup::getGlobal/setGlobal mechanism
Summary:
Ref T8424. Fixes T7114. This was envisioned as a per-request cache for reusing interpreters, but isn't a good fit for that in modern Phabricator.

In particular, it isn't loaded by the daemons, but they have equal need for per-request caching.

Since I finally need such a cache for Spaces, throw the old stuff away before I built a more modern cache.

Also resolves T7114 by dropping filtering on $_SERVER. I'm pretty sure this is the simplest fix, see D12977 for a bit more discussion.

Test Plan: Called `didFatal()` from somewhere in normal code and verified it was able to use the access log.

52b9e5ec14 Filter potentially problematic $_ENV variables
Summary:
Caught this in the production error logs. We can end up with `argv` defined and set to an array in an nginx + php-fpm configuration.

When we later run `ExecFuture` subprocesses, they won't be able to forward the value.

The error this produces looks like this:

ebcab8edb6 Namespace Aphlict clients by request path, plus other fixes
Summary:
Fixes T7130. Fixes T7041. Fixes T7012.

Major change here is partitioning clients. In the Phacility cluster, being able to get a huge pile of instances on a single server -- without needing to run a process per instance -- is desirable.

To accomplish this, just bucket clients by the path they connect with. This will let us set client URIs to `/instancename/` and then route connections to a small set of servers. This degrades cleanly in the common case and has no effect on installs which don't do instancing.

Also fix two unrelated issues:

  - Fix the timeouts, which were incorrectly initializing in `open()` (which is called during reconnect, causing them to reset every time). Instead, initialize in the constructor. Cap timeout at 5 minutes.
  - Probably fix subscriptions, which were using a property with an object definition. Since this is by-ref, all concrete instances of the object share the same property, so all users would be subscribed to everything. Probably.

Test Plan:
  - Hit notification status page, saw version bump and instance/path name.
  - Saw instance/path name in client and server logs.
  - Stopped server, saw reconnects after 2, 4, 16, ... seconds.
  - Sent test notification; received test notification.
  - Didn't explicitly test the subscription thing but it should be obvious by looking at `/notification/status/` shortly after a push.

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)

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.

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.

08126d3904 Improve top-level exception handling
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.

cae59d8345 Add an option to make it easier to debug page hangs
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.

41a8837f78 Make HTTP errors returned from the Aphlict server more specific
Summary: Ref T5651. Currently, the Aphlict server returns either `200 OKAY` or `400 Bad Request`. We could return more specific errors in some cases and this may assist with debugging.

Test Plan:
Sent myself a test notification at `/notification/status/` and saw the Aphlict server process the request (running in debug mode). Also poked around with `curl`:

```
> curl http://localhost:22281/
405 Method Not Allowed

> curl http://localhost:22281/ -d ""
400 Bad Request

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.

Instead:

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

Summary: Ref T5284. When an `AphlictClient` is closed, it will eventually be purged from the pool by the `AphlictMaster`. When this happens, also unsubscribe the purged client from all notifications, and send an `unsubscribe` command to the Aphlict server if possible.

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. Instead of broadcasting a notification to all clients (after which the clients can poll `/notification/individual` in order to determine whether or not they are interested in the notification), transmit notifications only to clients that have subscribed to a PHID that is relevant to the notification.

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.

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

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',
  ),
);
```

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.

4d0935ba5e Rate limit requests by IP
Summary:
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).

Test Plan: Used `ab` and reloading over and over again to hit rate limits. Read documentation.

Summary:
Ref T4324. The server code is probably going to get a fair amount more complicated, so allow it to load Javelin classes in a mostly-reasonable way.

This integration has a few warts, but should be good enough to let us manage complexity through the next iteration of the server.

(Mostly I just want the concicse Javelin mechanism for defining new classes.)

- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
