Summary:
Ref T8659. In the general case, this eventually allows build processes to do things like:
- Upload build results (like a ".app" or ".exe" or other binary).
- Pass complex results between build steps (e.g., build step A does something hard and build step B uses it to do something else).
Today, we're a long way away from having the infrastructure for that. However, it is useful to let third party build processes (like Jenkins) upload URIs that link back to the external build results.
This adds `harbormaster.createartifact` so they can do that. The only useful thing to do with this method today is have your Jenkins build do this:
params = array(
"uri": "https://jenkins.mycompany.com/build/23923/details/",
"name": "View Build Results in Jenkins",
"ui.external": true,
);
harbormaster.createartifact(target, 'uri', params);
Then (after the next diff) we'll show a link in Differential and a prominent link in Harbormaster. I didn't actually do the UI stuff in this diff since it's already pretty big.
This change moves a lot of code around, too:
- Adds PHIDs to artifacts.
- It modularizes build artifact types (currently "file", "host" and "URI").
- It formalizes build artifact parameters and construction:
- This lets me generate usable documentation about how to create artifacts.
- This prevents users from doing dangerous or policy-violating things.
- It does some other general modernization.

Summary:
Ref T8095. Two general problems:
- I want Harbormaster to own all lint and unit test results.
- I don't want users to have to configure anything for `arc` to keep working automatically.
These are in conflict because generic lint/unit test ownership in Harbormaster requires that build targets exist which we can attach build results to. However, we can't currently create build targets on demand: Harbormaster assumes it is responsible for creating targets, then running code or making third-party service calls to actually run the builds.
I considered two broad approaches to let `arc` push results into Harbormaster without requiring administrators to configure some kind of "arc results" build plan:
# Add magic target PHIDs like `PHID-MAGIC-this-is-really-arc-unit`.
# Add new code to build real targets with real PHIDs.
(1) is probably a bit less work to get off the ground, but I think it's worse overall and very likely to create more problems in the long run. I particularly worry that it will lead to a small amount of special casing in a very large number of places, which seems more fragile.
(2) is more work upfront but I think does a better job of putting all the special casing in one place that we can, e.g., more reasonably unit test, and letting the rest of the code rarely/never care about this case since it's just dealing with normal plans/steps/targets as far as it can tell.
This diff introduces "autoplans", which are source templates for plans/steps. This let us "push" these targets into Harbormaster. Hypthetically, any process "like" arc can use autoplans to upload test/lint/etc results. In practice, probably only `arc` will ever use this, but I think it's still quite a bit cleaner than the alternative despite all the generality.
Workflow is basically:
- `arc` creates a diff.
- `arc` calls `harbormaster.queryautotargets`, passing the diff PHID and saying "I have some lint and unit results I want to stick on this thing".
- Harbormaster builds the plan, steps, and targets (if any of them don't already exist), and hands back the target PHIDs so `arc` has a completely standard-looking place to put results.
- `arc` uploads the test results to the right targets, as though Harbormaster had asked it to run unit/lint in the first place.
(This doesn't actually do any of that yet, just sets things up.)
I'll maybe doc turn that ^^^^^^ into a doc for posterity since I think it's hard to guess what an "autotarget" is, but I'm going to grab some lunch first.
Test Plan:
- Added unit tests to make sure we can build these things properly.
- Used `harbormaster.queryautotargets` to build autotargets for a bunch of diffs.
- Verified targets come up in "waiting for message" state.
- Verified plans and steps are not editable.

Summary:
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`.

Summary:
Ref T1049. Generally, it's useful to separate test/trial/manual runs from production/automatic runs.
For example, you don't want to email a bunch of people that the build is broken just because you messed something up when writing a new build plan. You'd rather try it first, then promote it into production once you have some good runs.
Similarly, test runs generally should not affect the outside world, etc. Finally, some build steps (like "wait for other buildables") may want to behave differently when run in production/automation than when run in a testing environment (where they should probably continue immediately).
So, formalize the distinction between automatic buildables (those created passively by the system in response to events) and manual buildables (those created explicitly by users). Add filtering, and stop the automated parts of the system from interacting with the manual parts (for example, we won't show manual results on revisions).
This also moves the "Apply Build Plan" to a third, new home: instead of the sidebar or Buildables, it's now on plans. I think this generally makes more sense given how things have developed. Broadly, this improves isolation of test environments.
Test Plan: Created some builds, browsed around, used filters, etc.
