Fixes T7291. There are a class of spam/annoyance attacks here that we should be more strict about preventing, since you can add an individual's address as a mailing list.

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.

ab8f7907de Herald - add support for application emails.
Summary:
Fixes T5039. The trick / possibly lame part here is we only match 1 application email and its undefined which one. e.g. if a user emails us at address x, y, and z only one of those will pick up the mail. Ergo, don't let users define non-sensical herald conditions like "matches all". Also document what I think was non-intuitive about the code with an inline comment; we have to return an array with just a phid from an object and out of context it feels very "what the...???"

Note this needs to be deployed to other applications still, but I think its okay to close T5039 aggressively here since its done from a user story perspective.

Test Plan: set up a herald rule to flag tasks created as blue via app email x. sent an email to x via `bin/mail receive-test` and verified the task had the blue flag

9b359affe7 Prepare SSH connections for proxying
Summary:
Ref T7034.

In a cluster environment, when a user connects with a VCS request over SSH (like `git pull`), the receiving server may need to proxy it to a server which can actually satisfy the request.

In order to proxy the request, we need to know which repository the user is interested in accessing.

Split the SSH workflow into two steps:

  # First, identify the repository.
  # Then, execute the operation.

In the future, this will allow us to put a possible "proxy the whole thing somewhere else" step in the middle, mirroring the behavior of Conduit.

This is trivially easy in `git` and `hg`. Both identify the repository on the commmand line.

This is fiendishly complex in `svn`, for the same reasons that hosting SVN was hard in the first place. Specifically:

  - The client doesn't tell us what it's after.
  - To get it to tell us, we have to send it a server capabilities string //first//.
  - We can't just start an `svnserve` process and read the repository out after a little while, because we may need to proxy the request once we figure out the repository.
  - We can't consume the client protocol frame that tells us what the client wants, because when we start the real server request it won't know what the client is after if it never receives that frame.
  - On the other hand, we must consume the second copy of the server protocol frame that would be sent to the client, or they'll get two "HELLO" messages and not know what to do.

The approach here is straightforward, but the implementation is not trivial. Roughly:

  - Start `svnserve`, read the "hello" frame from it.
  - Kill `svnserve`.
  - Send the "hello" to the client.
  - Wait for the client to send us "I want repository X".
  - Save the message it sent us in the "peekBuffer".
  - Return "this is a request for repository X", so we can proxy it.

Then, to continue the request:

  - Start the real `svnserve`.
  - Read the "hello" frame from it and throw it away.
  - Write the data in the "peekBuffer" to it, as though we'd just received it from the client.
  - State of the world is normal again, so we can continue.

Also fixed some other issues:

  - SVN could choke if `repository.default-local-path` contained extra slashes.
  - PHP might emit some complaints when executing the commit hook; silence those.

Test Plan: Pushed and pulled repositories in SVN, Mercurial and Git.

eaa883cf37 Fix anchor-clicking scroll positions
Summary:
Fixes T7069. When jumping to a comment anchor, we get the scroll positions wrong.

Partly this is fixing some calcaulations; partly, the "show older comments" and "scroll anchor" stuff were fighting over the scroll position. Since the anchor can take care of things on its own, just let it handle stuff.

Test Plan:
  - Clicked comment anchors.
  - Loaded pages with anchors in the URI.
  - Loaded pages with anchors hidden behind "show older comments".

In all cases, got the right scroll position.

48f15fb960 Update stock Homepage to look like Dashboards
Summary: Swaps out AphrontPanels for ObjectBoxes. I'd like to start reducing the floating object lists around the site for consistency. Also, these should provide more items above the fold.

Test Plan:
Test on my local homepage. Built a fake welcome.html too, though I think that's deprecated.

5c71da8cdb Quicksand, an ignoble successor to Quickling
Summary:
Ref T2086. Ref T7014. With the persistent column, there is significant value in retaining chrome state through navigation events, because the user may have a lot of state in the chat window (scroll position, text selection, room juggling, partially entered text, etc). We can do this by capturing navigation events and faking them with Javascript.

(This can also improve performance, albeit slightly, and I believe there are better approaches to tackle performance any problems which exist with the chrome in many cases).

At Facebook, this system was "Photostream" in photos and then "Quickling" in general, and the technical cost of the system was //staggering//. I am loathe to pursue it again. However:

  - Browsers are less junky now, and we target a smaller set of browsers. A large part of the technical cost of Quickling was the high complexity of emulating nagivation events in IE, where we needed to navigate a hidden iframe to make history entries. All desktop browsers which we might want to use this system on support the History API (although this prototype does not yet implement it).
  - Javelin and Phabricator's architecture are much cleaner than Facebook's was. A large part of the technical cost of Quickling was inconsistency, inlined `onclick` handlers, and general lack of coordination and abstraction. We will have //some// of this, but "correctly written" behaviors are mostly immune to it by design, and many of Javelin's architectural decisions were influenced by desire to avoid issues we encountered building this stuff for Facebook.
  - Some of the primitives which Quickling required (like loading resources over Ajax) have existed in a stable state in our codebase for a year or more, and adoption of these primitives was trivial and uneventful (vs a huge production at Facebook).
  - My hubris is bolstered by recent success with WebSockets and JX.Scrollbar, both of which I would have assessed as infeasibly complex to develop in this project a few years ago.

To these points, the developer cost to prototype Photostream was several weeks; the developer cost to prototype this was a bit less than an hour. It is plausible to me that implementing and maintaining this system really will be hundreds of times less complex than it was at Facebook.

Test Plan:
My plan for this and D11497 is:

  - Get them in master.
  - Some secret key / relatively-hidden preference activates the column.
  - Quicksand activates //only// when the column is open.
  - We can use column + quicksand for a long period of time (i.e., over the course of Conpherence v2 development) and hammer out the long tail of issues.
  - When it derps up, you just hide the column and you're good to go.
