Summary:
Fixes T9994. Currently, when Drydock can't allocate a new resource because some limit has been reached, it waits patiently for a resource to become available.
It is possible that no resource will ever become available. Particularly with "Working Copy" resources, the new lease may want a copy of `rB`, but the resource may already be maxed out on `rA`.
Right now, no process exists to automatically reclaim the unused `rA`.
When we encounter this situation, try to reclaim one of the other resources if it is just sitting there unused.
Specifically:
- Add a "reclaim" command which means "release this resource //if// it is completely unused".
- Add a `bin/drydock reclaim` to send this command to every active resource.
- When we try to acquire a resource and can't, but only because of some kind of limit / utilization problem, try to release an unused resource to free up some room.
Test Plan:
- Set "Working Copy" resource limit to 1.
- Ran "Test Configuration" in `rA`, which worked.
- Ran "Test Configuration" in `rB`, which hung forever.
- Applied patch.
- Ran "Test Configuration" in `rB`, saw it reclaim the `rA` resource, use the slot, then succeed.

Summary:
Ref T9994. This fixes the first issue discussed on that task, which is that when a merge fails after "arc land", we would not clean up all the leases properly.
Specifically, when a merge fails, we use `queueTask()` to schedule a followup task. This followup destroys the lease and frees the underlying resource.
However, the default behavior of `queueTask()` is to //not queue tasks// if the parent task fails. This is a reasonable, safe behavior that was originally introduced in D8774, where it kept us from sending too much mail if a task did "send some mail" and then failed a little later on and got retried.
Since I think the default behavior is correct, I just special cased the behavior for Drydock to make it queue even on failure. These are the only types of followup tasks we currently want to queue on main task failure.
(It's possible that future Blueprints might want some kind of more specialized behavior, where some tasks queue only on success, but we can cross that bridge when we come to it.)
Test Plan:
- See T9994#149878 for test case setup.
- I ran that test case again with this patch, and saw the followup task queue properly in the `--trace` log, a correspoinding update task show up in `/daemon/`, and the lease get destroyed when I ran it a moment later.

Summary:
Ref T9252. Right now, we have very strict limits on Drydock: one lease per host, and one working copy per working copy blueprint.
These are silly and getting in the way of using "Land Revision" more widely, since we need at least one working copy for each landable repository.
For now, just remove the host limit and put a simple limit on working copies. This might need to be fancier some day (e.g., limit working copies per-host) but it is generally reasonable for the use cases of today.
Also add a `--background` flag to make testing a little easier.
(Limits are also less important nowadays than they were in the past, because pools expand slowly now and we seem to have stamped out all the "runaway train" bugs where allocators go crazy and allocate a million things.)
Test Plan:
- With a limit of 5, ran 10 concurrent builds and saw them finish after allocating 5 total resources.
- Removed limit, raised taskmaster concurrency to 128, ran thousands of builds in blocks of 128 or 256.
- Saw Drydock gradually expand the pool, allocating a few more working copies at first and a lot of working copies later.
- Got ~256 builds in ~140 seconds, which isn't a breakneck pace or anything but isn't too bad.

Summary:
Ref T9252. This fixes a bug from D14236. D14272 discusses the observable effects of the bug, primarily that the window for racing is widened from ~a few milliseconds to several minutes under our configuration.
This SQL query is missing a `GROUP BY` clause, so all of the resources get counted as having the same status (specifically, the alphabetically earliest status any resource had, I think). For test cases this often gets the right result since the number of resources may be small and they may all have the same status, but in production this isn't true. In particular, the allocator would sometimes see "35 destroyed resources" (or whatever), when the real counts were "32 destroyed resources + 3 pending resources".
Since this allocator behavior is soft/advisory this didn't cause any actual problems, per se (we do expect races here occasionally), it just made the race very very easy to hit. For example, Drydock in production currently has three pending working copy resources. Although we do expect this to be //possible//, getting 4 resources when the configured limit is 1 should be hard (not lightning strike / cosmic radiaion hard, but "happens once a year" hard).
Also exclude destroyed resources since we never care about them.
Test Plan:
Followed the plan from D14272 and restarted two Harbormaster workers at the same time.
After this patch was applied, they no longer created two different resources (we expect it to be possible for this to happen, just very hard).
We should still be able to force this race by putting something like `sleep(10)` right before the query, then `sleep(10)` right after it. That would prevent the allocators from seeing one another (so they would both think there were no other resources) and push us down the pathway where we exceed the soft limit.

Summary:
Ref T9252. This is mostly a fix for an edge case from D14236. Here's the setup:
- There are no resources.
- A request for a new resource arrives.
- We build a new resource.
Now, if we were leasing an existing resource, we'd call `canAcquireLeaseOnResource()` before acquiring a lease on the new resource.
However, for new resources we don't do that: we just acquire a lease immediately. This is wrong, because we now allow and expect some resources to be unleasable when created.
In a more complex workflow, this can also produce the wrong result and leave the lease acquired sub-optimally (and, today, deadlocked).
Make the "can we acquire?" pathway consistent for new and existing resources, so we always do the same set of checks.
Test Plan:
- Started daemons.
- Deleted all working copy resources.
- Ran two working-copy-using build plans at the same time.
- Before this change, one would often [1] acquire a lease on a pending resource which never allocated, then deadlock.
- After this change, the same thing happens except that the lease remains pending and the work completes.
[1] Although the race this implies is allowed (resource pool limits are soft/advisory, and it is expected that we may occasionally run over them), it's MUCH easier to hit right now than I would expect it to be, so I think there's probably at least one more small bug here somewhere. I'll see if I can root it out after this change.

Summary:
Ref T9519. This is like 80% of the way there and doesn't fully work yet, but roughly shows the shape of things to come. Here's how it works:
First, there's a new custom field type for blueprints which works like a normal typeahead but has some extra logic. It's implemented this way to make it easy to add to Blueprints in Drydock and Build Plans in Harbormaster. Here, I've added a "Use Blueprints" field to the "WorkingCopy" blueprint, so you can control which hosts the working copies are permitted to allocate on:
{F869865}
This control has a bit of custom rendering logic. Instead of rendering a normal list of PHIDs, it renders an annotated list with icons:
{F869866}
These icons show whether the blueprint on the other size of the authorization has approved this object. Once you have a green checkmark, you're good to go.
On the blueprint side, things look like this:
{F869867}
This table shows all the objects which have asked for access to this blueprint. In this case it's showing that one object is approved to use the blueprint since I already approved it, but by default new requests come in here as "Authorization Requested" and someone has to go approve them.
You approve them from within the authorization detail screen:
{F869868}
You can use the "Approve" or "Decline" buttons to allow or prevent use of the blueprint.
This doesn't actually do anything yet -- objects don't need to be authorized in order to use blueprints quite yet. That will come in the next diff, I just wanted to get the UI in reasonable shape first.
The authorization also has a second piece of state, which is whether the request from the object is active or inactive. We use this to keep track of the authorization if the blueprint is (maybe temporarily) deleted.
For example, you might have a Build Plan that uses Blueprints A and B. For a couple days, you only want to use A, so you remove B from the "Use Blueprints: ..." field. Later, you can add B back and it will connect to its old authorization again, so you don't need to go re-approve things (and if you're declined, you stay declined instead of being able to request authorization over and over again). This should make working with authorizations a little easier and less labor intensive.
Stuff not in this diff:
- Actually preventing any allocations (next diff).
- Probably should have transactions for approve/decline, at least, at some point, so there's a log of who did approvals and when.
- Maybe should have a more clear/loud error state when no blueprints are approved?
- Should probably restrict the typeahead to specific blueprint types.
Test Plan:
- Added the field.
- Typed some stuff into it.
- Saw the UI update properly.
- Approved an authorization.
- Declined an authorization.
- Saw active authorizations on a blueprint page.
- Didn't see any inactive authroizations there.
- Clicked "View All Authorizations", saw all authorizations.

Summary:
Ref T9252. I think there's a more complex version of this problem discussed elsewhere, but here's what we hit today:
- 5 commits land at the same time and trigger 5 builds.
- All of them go to acquire a working copy.
- Working copies have a limit of 1 right now, so 1 of them gets the lease on it.
- The other 4 all trigger allocation of //new// working copies. So now we have: 1 active, leased working copy and 4 pending, leased working copies.
- The 4 pending working copies will never activate without manual intervention, so these 4 builds are stuck forever.
To fix this, prevent WorkingCopies from giving out leases until they activate. So now the leases won't acquire until we know the working copy is good, which solves the first problem.
However, this creates a secondary problem:
- As above, all 5 go to acquire a working copy.
- One gets it.
- The other 4 trigger allocations, but no longer acquire leases. This is an improvement.
- Every time the leases update, they trigger another allocation, but never acquire. They trigger, say, a few thousand allocations.
- Eventually the first build finishes up and the second lease acquires the working copy. After some time, all of the builds finish.
- However, they generated an unboundedly large number of pending working copy resources during this time.
This is technically "okay-ish", in that it did work correctly, it just generated a gigantic mess as a side effect.
To solve this, at least for now, provide a mechanism to impose allocation rate limits and put a cap on the number of allocating resources of a given type. As hard-coded, this the greater of "1" or "25% of the active resources in the pool".
So if there are 40 working copies active, we'll start allocating up to 10 more and then cut new allocations off until those allocations get sorted out. This prevents us from getting runaway queues of limitless size.
This also imposes a total active working copy resource limit of 1, which incidentally also fixes the problem, although I expect to raise this soon.
These mechanisms will need refinement, but the basic idea is:
- Resources which aren't sure if they can actually activate should wait until they do activate before allowing leases to acquire them. I'm fairly confident this rule is a reasonable one.
- Then we limit how many bookkeeping side effects Drydock can generate once it starts encountering limits.
Broadly, some amount of mess is inevitable because Drydock is allowed to try things that might not work. In an extreme case we could prevent this mess by setting all these limits at "1" forever, which would degrade Drydock to effectively be a synchronous, blocking queue.
The idea here is to put some amount of slack in the system (more than zero, but less than infinity) so we get the performance benefits of having a parallel, asyncronous system without a finite, manageable amount of mess.
Numbers larger than 0 but less than infinity are pretty tricky, but I think rules like "X% of active resources" seem fairly reasonable, at least for resources like working copies.
Test Plan:
Ran something like this:
```
for i in `seq 1 5`; do sh -c '(./bin/harbormaster build --plan 10 rX... &) &'; done;
```
Saw 5 plans launch, acquire leases, proceed in an orderly fashion, and eventually finish successfully.

Summary:
Ref T9252. Currently, Harbormaster and Drydock work like this in some cases:
# Queue a lease for activation.
# Then, a little later, save the lease PHID somewhere.
# When the target/resource is destroyed, destroy the lease.
However, something can happen between (1) and (2). In Drydock this window is very short and the "something" would have to be a lighting strike or something similar, but in Harbormaster we wait until the resource activates to do (2) so the window can be many minutes long. In particular, a user can use "Abort Build" during those many minutes.
If they do, the target is destroyed but it doesn't yet have a record of the artifact, so the artifact isn't cleaned up.
Make these things work like this instead:
# Create a new lease and pre-generate a PHID for it.
# Save that PHID as something that needs to be cleaned up.
# Queue the lease for activation.
# When the target/resource is destroyed, destroy the lease if it exists.
This makes sure there's no step in the process where we might lose track of a lease/resource.
Also, clean up and standardize some other stuff I hit.
Test Plan:
- Stopped daemons.
- Restarted a build in Harbormaster.
- Stepped through the build one stage at a time using `bin/worker execute ...`.
- After the lease was queued, but before it activated, aborted the build.
- Processed the Harbormaster side of things only.
- Saw the lease get destroyed properly.

Summary:
Fixes T9494. This:
- Removes all the random GC.x.y.z config.
- Puts it all in one place that's locked and which you use `bin/garbage set-policy ...` to adjust.
- Makes every TTL-based GC configurable.
- Simplifies the code in the actual GCs.
Test Plan:
- Ran `bin/garbage collect` to collect some garbage, until it stopped collecting.
- Ran `bin/garbage set-policy ...` to shorten policy. Saw change in web UI. Ran `bin/garbage collect` again and saw it collect more garbage.
- Set policy to indefinite and saw it not collect garabge.
- Set policy to default and saw it reflected in web UI / `collect`.
- Ran `bin/phd debug trigger` and saw all GCs fire with reasonable looking queries.
- Read new docs.

Summary:
Ref T9252. This primarily allows Harbormaster to request (and Drydock to fulfill) working copies with a patch from a staging area. Doing this means we can do builds on in-review changes from `arc diff`.
This is a little cobbled-together but should basically work.
Also fix some other issues:
- Yielded, awakend workers are fine to update but could complain.
- We can't log slot lock failures to resources if we don't end up saving them.
- Killing the transaction would wipe out the log.
- Fix some TODOs, etc.
Test Plan: Ran Harbormaster builds on a local revision.

Summary:
Ref T9252. Long ago you sometimes manually created resources, so they had human-enterable names. However, users never make resources manually any more, so this field isn't really useful any more.
In particular, it means we write a lot of untranslatable strings like "Working Copy" to the database in the default locale. Instead, do the call at runtime so resource names are translatable.
Also clean up a few minor things I hit while kicking the tires here.
It's possible we might eventually want to introduce a human-choosable label so you can rename your favorite resources and this would just be a default name. I don't really have much of a use case for that yet, though, and I'm not sure there will ever be one.
Test Plan:
- Restarted a Harbormaster build, got a clean build.
- Released all leases/resources, restarted build, got a clean build with proper resource names.
