Summary:
Ref T3551. Currently, ReleephRequests don't have a direct concept of the //object// being requested. You can request `D123`, but that is just a convenient way to write `rXyyyy`.
When the UI wants to display information about a revision, it deduces it by examining the commit.
This is primarily an attack on T3551, so we don't need to load <commit -> edge -> revision> (in an ad-hoc way) to get revisions. Instead, when you request a revision we keep track of it and can load it directly later.
Later, this will let us do more things: for example, if you request a branch, we can automatically update the commits (as GitHub does), etc. (Repository branches will need PHIDs first, of course.)
This adds and populates the column but doesn't use it yet. The second part of the migration could safely be run while Phabricator is up, although even for Facebook this table is probably quite small.
Test Plan:
- Ran migration.
- Verified existing requests associated sensibly.
- Created a new commit request.

For Harbormaster tasks which want to poll or wait, this lets them say "try again a little later" without having to sleep and hold a queue slot.
This is basically the same as failing, except that we don't increment the failure counter. Instead, we just set the current lease to the correct length and then exit. The task will be retried after the lease expires.
Test Plan: Using both `bin/harbormaster` and `phd debug taskmaster`, ran a lot of waiting tasks through the queue, faking them to either yield or not yield in a controlled manner. The queue responded as expected, yielding tasks appropraitely and retrying them later.

Summary:
This hooks up all the pieces of the build pipeline so `harbormaster.sendmessage` actually works. Particularly:
- Candidate build steps (i.e., those which interact with external systems) can now "Wait for Message". This pauses them indefinitely when they complete, until something calls `harbormaster.sendmessage`.
- After processing a target, we check if we should move it to PASSED or WAITING.
- Before updating a build, we move WAITING targets with pending messages to either PASSED or FAILED.
- I added an explicit "Building" state, which doesn't affect workflows but communicates more information to human users.
A big part of this is avoiding races. I believe we get the correct behavior no matter which order events occur in:
- We update builds after targets complete and after we receive messages, so we're guaranteed to update once both these conditions are true. This means messages can't be lost (even if they arrive before a build completes).
- The minor changes to the build engine logic mean that firing additional build updates is always safe, no matter what the current state of the build is.
- The build itself is protected by a lock in the build engine.
- The target is not covered by an explicit lock, but for all states only the engine (waiting) //or// the worker (all other states) can interact with it. All of the interactions also move the target state forward to the same destination and have no other side effects.
- Messages are only consumed inside the engine lock, so they don't need an explicit lock.
Test Plan:
- Made an HTTP request wait after completion, then ran a pile of builds through it using `bin/harbormaster build` and the web UI.
- Passed and failed message-awaiting builds with `harbormaster.sendmessage`.

This will let the parent process focus on scheduling in a more understandable way and update multiple repositories at once.

Fixes T4802. For context, see T1921.
Originally (in T1921), a developer ran into an issue where rendering `phabricator_form()` with an absolute URI confusingly dropped CSRF tokens, and it wasn't obvious why. This is a security measure, but at the time it wasn't very clear how all the pieces fit together. To make it more clear, we:
# expanded the exception text in developer mode to include a description of this issue; and
# added an exception in developer mode when rendering a form like this.
However, (2) causes some undesirable interactions for file downloads. In particular, if:
- developer mode is on; and
- there's no alternate file domain configured; and
- you try to download a file...
...we produce CDN URIs that are fully-qualified, and you get the exception from (2) above.
This is kind of a mess, and producing fully-qualified CDN URIs in all cases is simple and clear and desirable. To resolve this, just revert (2). We still have the clarification from (1) above and this hasn't caused further issues, so I think that's sufficient. This is a rare issue anyway and not particularly serious or error prone (at worst, a bit confusing and annoying, but hopefully easy to understand and resolve after the changes in (1)).
Test Plan: With develper mode and no alternate file domain, downloaded files from Files.

Summary:
See discussion in D8773. Three small adjustments which should help prevent this kind of issue:
- When queueing followup tasks, hold them on the worker until we finish the task, then queue them only if the work was successful.
- Increase the default lease time from 60 seconds to 2 hours. Although most tasks finish in far fewer than 60 seconds, the daemons are generally stable nowadays and these short leases don't serve much of a purpose. I think they also date from an era where lease expiry and failure were less clearly distinguished.
- Increase the default wait-after-failure from 60 seconds to 5 minutes. This largely dates from the MetaMTA era, where Facebook ran services with high failure rates and it was appropriate to repeatedly hammer them until things went through. In modern infrastructure, such failures are rare.
Test Plan:
- Verified that tasks queued properly after the main task was updated.
- Verified that leases default to 7200 seconds.
- Intentionally failed a task and verified default 300 second wait before retry.
- Removed all default leases shorter than 7200 seconds (there was only one).
- Checked all the wait before retry implementations for anything much shorter than 5 minutes (they all seem reasonable).

Recently we see issues with huge commits (branch cuts for www) where people received hundreds of emails for the same commit. By checking all the active and archived tasks related to such commits, I saw the following pattern:
- The commit itself is marked as importStatus = 15 which means all the processing was actually done;
- In archived tasks, I see one PhabricatorRepositorySvnCommitMessageParserWorker, one PhabricatorRepositorySvnCommitChangeParserWorker, followed by many PhabricatorRepositoryCommitHeraldWorker, which means that the PhabricatorRepositoryCommitOwnersWorker (who schedule those herald tasks) was never done;
- PhabricatorRepositoryCommitOwnersWorker is always active (for days) with failureCount = 0;
- In daemon log I see a lot of lease expire exception for PhabricatorRepositoryCommitOwnersWorker.
So to me it looks like the following happened:
- Everything is fine until we schedule the PhabricatorRepositoryCommitOwnersWorker
- PhabricatorRepositoryCommitOwnersWorker actually successfully finished but its running time exceed 60s. Before it finishes, it scheduled the PhabricatorRepositoryCommitHeraldWorker task
- When we try to archive it, the lease expiration exception happened. As a result, it stayed active and will be picked up immediately since it is in the head of the queue
- The two steps above repeat forever until we kill it
I am not sure why we want to check lease expiration when we are archiving the task. For now I am giving the worker a little more time since parsing half million affected path needs some time..
Test Plan: Patched in our production and it worked.
