e595478f1d Make policy violation dialog more flexible
Summary:
Ref T8424. When users are rejected because they can't see the space an object is in, this isn't really a capability rejection. Don't require a capability when rejecting objects.

This mostly simplifies upcoming changes.

Test Plan:
  - Viewed a capability exception dialog, it looked the same as always.
  - (After additional changes, viewed a space exception dialog.)

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.

db1cd65866 Allow setup checks to perform writes
Summary:
Fixes T8198. Currently, if the `policy.locked` configuration setting includes a value which is a user PHID, we may perform a cache fill during setup as a side effect of validating it.

Right now, there is no WriteGuard active during setup, because we don't have a Request object yet so we can't actually perform CSRF validation.

Two possible approaches are:

  # Prevent the write from occuring.
  # Change the code to allow the write.

In the past, I think we've hit similar cases and done (1). However, IIRC those writes were sketchier, more isolated, and easy to remove (I think there was one with PKCS8 keys). This one is pretty legit and not very easy to remove without making a bit of a mess.

There's no techncial reason we can't do (2), we just have to create a no-op WriteGuard for the setup phase.

Test Plan:
  - To reproduce this issue: set some value in `policy.locked` to a user PHID, then wipe out profile caches in the database, then restart the webserver.
  - Reproduced the issue.
  - Added the new dummy write guard, fixed a minor issue with disposal semantics (see D12841).
  - Verified this fixed the issue.
  - Added a `throw` to the real CSRF validator and performed a real write. Verified I got CSRF-blocked.
  - Removed a CSRF token from a form and double-checked that CSRF protection still works.

59416a13e7 Add "request time" event and viewer and context data to Multimeter

Only notable thing here is that I prevented non-admins from slicing down by viewing user, since it feels a little creepy to go see what pages you looked at, even though we only show which controllers you invoked.

7b6c320e15 Skeleton for "Multimeter", a performance sampling application
Summary:
Ref T6930. This application collects and displays performance samples -- roughly, things Phabricator spent some kind of resource on. It will collect samples on different types of resources and events:

  - Wall time (queries, service calls, pages)
  - Bytes In / Bytes Out (requests)
  - Implicit requests to CSS/JS (static resources)

I've started with the simplest case (static resources), since this can be used in an immediate, straghtforward way to improve packaging (look at which individual files have the most requests recently).

There's no aggregation yet and a lot of the data isn't collected properly. Future diffs will add more dimension data (controllers, users), more event and resource types (queries, service calls, wall time), and more display options (aggregation, sorting).

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.

fa7bb8ff7a Add cluster.addresses and require membership before accepting cluster authentication tokens
Summary:
Ref T2783. Ref T6706.

  - Add `cluster.addresses`. This is a whitelist of CIDR blocks which define cluster hosts.
  - When we recieve a request that has a cluster-based authentication token, require the cluster to be configured and require the remote address to be a cluster member before we accept it.
    - This provides a general layer of security for these mechanisms.
    - In particular, it means they do not work by default on unconfigured hosts.
  - When cluster addresses are configured, and we receive a request //to// an address not on the list, reject it.
    - This provides a general layer of security for getting the Ops side of cluster configuration correct.
    - If cluster nodes have public IPs and are listening on them, we'll reject requests.
    - Basically, this means that any requests which bypass the LB get rejected.

Test Plan:
  - With addresses not configured, tried to make requests; rejected for using a cluster auth mechanism.
  - With addresses configred wrong, tried to make requests; rejected for sending from (or to) an address outside of the cluster.
  - With addresses configured correctly, made valid requests.

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.

db51d7d92a Make ConduitCall always local/in-process
Summary:
Ref T2783. ConduitCall currently has logic to pick a random remote server, but this is ultimately not appropriate: we always want to send requests to a specific server. For example, we want to send repository requests to a server which has that repository locally. The repository tier is not homogenous, so we can't do this below the call level.

Make ConduitCall always-local; logic above it will select ConduitCall for an in-process request or do service selection for an off-host request via ConduitClient.

Test Plan:
  - Browsed some pages using ConduitCall, everything worked.
  - Grepped for removed stuff.

9352c76e81 Decouple some aspects of request routing and construction
Summary:
Ref T5702. This is a forward-looking change which provides some very broad API improvements but does not implement them. In particular:

  - Controllers no longer require `$request` to construct. This is mostly for T5702, directly, but simplifies things in general. Instead, we call `setRequest()` before using a controller. Only a small number of sites activate controllers, so this is less code overall, and more consistent with most constructors not having any parameters or effects.
  - `$request` now offers `getURIData($key, ...)`. This is an alternate way of accessing `$data` which is currently only available on `willProcessRequest(array $data)`. Almost all controllers which implement this method do so in order to read one or two things out of the URI data. Instead, let them just read this data directly when processing the request.
  - Introduce `handleRequest(AphrontRequest $request)` and deprecate (very softly) `processRequest()`. The majority of `processRequest()` calls begin `$request = $this->getRequest()`, which is avoided with the more practical signature.
  - Provide `getViewer()` on `$request`, and a convenience `getViewer()` on `$controller`. This fixes `$viewer = $request->getUser();` into `$viewer = $request->getViewer();`, and converts the `$request + $viewer` two-liner into a single `$this->getViewer()`.

Test Plan:
  - Browsed around in general.
  - Hit special controllers (redirect, 404).
  - Hit AuditList controller (uses new style).

a2a0f002f0 Fix security.require-https by marking redirect as external
Summary:
Resolves T5937.  HTTPS redirects caused by `security.require-https` use a full scheme, domain and port in the URI.  Consequently, this causes invocation of the new external redirect logic and prevents redirection from occurring properly when accessing the HTTP version of Phabricator that has `security.require-https` turned on.

I've also fixed the automatic slash redirection logic to add the external flag where appropriate.

Test Plan: Configured SSL on my local machine and turned on `security.require-https`.  Observed the "Refusing to redirect" exception on master, while the redirect completed successfully with this patch.

847b7977c1 Add semi-generic rate limiting infrastructure
Summary:
This adds a system which basically keeps a record of recent actions, who took them, and how many "points" they were worth, like:

  epriestley email.add 1 1233989813
  epriestley email.add 1 1234298239
  epriestley email.add 1 1238293981

We can use this to rate-limit actions by examining how many actions the user has taken in the past hour (i.e., their total score) and comparing that to an allowed limit.

One major thing I want to use this for is to limit the amount of error email we'll send to an email address. A big concern I have with sending more error email is that we'll end up in loops. We have some protections against this in headers already, but hard-limiting the system so it won't send more than a few errors to a particular address per hour should provide a reasonable secondary layer of protection.

This use case (where the "actor" needs to be an email address) is why the table uses strings + hashes instead of PHIDs. For external users, it might be appropriate to rate limit by cookies or IPs, too.

To prove it works, I rate limited adding email addresses. This is a very, very low-risk security thing where a user with an account can enumerate addresses (by checking if they get an error) and sort of spam/annoy people (by adding their address over and over again). Limiting them to 6 actions / hour should satisfy all real users while preventing these behaviors.

Test Plan:
This dialog is uggos but I'll fix that in a sec:

ae7324fd5b Fix an anchor redirect issue with OAuth server, plus modernize the application a bit
Summary:
Ref T4593. Via HackerOne. An attacker can use the anchor reattachment, combined with the Facebook token workflow, combined with redirection on OAuth errors to capture access tokens. The attack works roughly like this:

  - Create an OAuth application on Phabricator.
  - Set the domain to `evil.com`.
  - Grab the OAuth URI for it (something like `https://phabricator.com/oauthserver/auth/?redirect_uri=http://evil.com&...`).
  - Add an invalid `scope` parameter (`scope=xyz`).
  - Use //that// URI to build a Facebook OAuth URI (something like `https://facebook.com/oauth/?redirect_uri=http://phabricator.com/...&response_type=token`).
  - After the user authorizes the application on Facebook (or instantly if they've already authorized it), they're redirected to the OAuth server, which processes the request. Since this is the 'token' workflow, it has auth information in the URL anchor/fragment.
  - The OAuth server notices the `scope` error and 302's to the attacker's domain, preserving the anchor in most browsers through anchor reattachment.
  - The attacker reads the anchor in JS and can do client workflow stuff.

To fix this, I've made several general changes/modernizations:

  - Add a new application and make it beta. This is mostly cleanup, but also turns the server off for typical installs (it's not generally useful quite yet).
  - Add a "Console" page to make it easier to navigate.
  - Modernize some of the UI, since I was touching most of it anyways.

Then I've made specific security-focused changes:

  - In the web-based OAuth workflow, send back a human-readable page when errors occur. I //think// this is universally correct. Previously, humans would get a blob of JSON if they entered an invalid URI, etc. This type of response is correct for the companion endpoint ("ServerTokenController") since it's called by programs, but I believe not correct for this endpoint ("AuthController") since it's used by humans. Most of this is general cleanup (give humans human-readable errors instead of JSON blobs).
  - Never 302 off this endpoint automatically. Previously, a small set of errors (notably, bad `scope`) would cause a 302 with 'error'. This exposes us to anchor reattachment, and isn't generally helpful to anyone, since the requesting application did something wrong and even if it's prepared to handle the error, it can't really do anything better than we can.
  - The only time we'll 'error' back now from this workflow is if a user explicitly cancels the workflow. This isn't a 302, but a normal link (the cancel button), so the anchor is lost.
  - Even if the application is already approved, don't blindly 302. Instead, show the user a confirmation dialog with a 'continue' link. This is perhaps slightly less user-friendly than the straight redirect, but I think it's pretty reasonable in general, and it gives us a lot of protection against these classes of attack. This redirect is then through a link, not a 302, so the anchor is again detached.
  -

Test Plan: I attempted to hit everything I touched. See screenshots.

7f5b15c6fa Made some classes final.
Summary:
Currently, the linter raises `XHP29` warnings for these files because they are not abstract or final.

I guess there are two possibly solutions, either making the classes final or marking them as `@concrete-extensible`. Given that there are no subclasses of these classes in the `phabricator`, `arcanist` and `libphutil` repositories... I opted to declare the classes as final.

Test Plan:
The following linter warnings are gone:

```
>>> Lint for src/aphront/configuration/AphrontDefaultApplicationConfiguration.php:

   Warning  (XHP29) Class Not abstract Or final
    This class is neither 'final' nor 'abstract', and does not have a
    docblock marking it '@concrete-extensible'.

               7   extends AphrontApplicationConfiguration {

75c4a185a9 Begin modularizing typeahead sources
Summary:
Ref T4420. This sets up the basics for modular typeahead sources. Basically, the huge `switch()` is just replaced with class-based runtime dispatch.

The only clever bit I'm doing here is with `CompositeDatasource`, which pretty much just combines the results from several other datasources. We can use this to implement some of the weird cases where we need multiple types of results, although I think I can entirely eliminate many of them entirely. It also makes top-level implementation simpler, since more logic can go inside the sources.

Sources are also application-aware, will be responsible for placeholder text, and have a slightly nicer debug view.

2c35532256 Drive all Celerity operations from the new map
Summary:
Ref T4222.

  - Removes the old map and changes the CelerityResourceMap API to be entirely driven by the new map.
  - The new map is about 50% smaller and organized more sensibly.
  - This removes the `/pkg/` URI component. All resources are now required to have unique names, so we can tell if a resource is a package or not by looking at the name.
  - Removes some junky old APIs.
  - Cleans up some other APIs.
  - Added some feedback for `bin/celerity map`.
  - `CelerityResourceMap` is still a singleton which is inextricably bound to the Phabricator map; this will change in the future.

Test Plan:
  - Reloaded pages.
  - Verified packaging works by looking at generated includes.
  - Forced minification on and verified it worked.
  - Forced no-timestamps on and verified it worked.
  - Rebuilt map.
  - Ran old script and verified error message.
  - Checked logs.

b1b1ff83f2 Allow applications to define new policy capabilities
Summary:
Ref T603. I want to let applications define new capabilities (like "can manage global rules" in Herald) and get full support for them, including reasonable error strings in the UI.

Currently, this is difficult for a couple of reasons. Partly this is just a code organization issue, which is easy to fix. The bigger thing is that we have a bunch of strings which depend on both the policy and capability, like: "You must be an administrator to view this object." "Administrator" is the policy, and "view" is the capability.

That means every new capability has to add a string for each policy, and every new policy (should we introduce any) needs to add a string for each capability. And we can't do any piecemeal "You must be a {$role} to {$action} this object" becuase it's impossible to translate.

Instead, make all the strings depend on //only// the policy, //only// the capability, or //only// the object type. This makes the dialogs read a little more strangely, but I think it's still pretty easy to understand, and it makes adding new stuff way way easier.

Also provide more context, and more useful exception messages.

Test Plan:
  - See screenshots.
  - Also triggered a policy exception and verified it was dramatically more useful than it used to be.
