Ref T9524. Because fetching the last time files were modified in Diffusion can be slow, we bring it in over Ajax.
The logic to fetch and paint the table is kind of fragile because there are two different definitions of the columns right now and we break in a bad way if they differ.
In particular, calling `diffusion.updatecoverage` can populate a "lint commit" for a repository, which tries to generate lint information in one of the views (but not the other one).
In the longer run I think we're removing some of the concepts here and this rendering should be rebuilt to not have two separate column definitions, but just make it degrade gracefully for now since those are larger changes.
Test Plan:
Reproduced the issue in T9524 by calling `diffusion.updatecoverage` on a repostiory. Specifically, this has a side effect of creating a "lint commit" which triggers a "lint" column in this table, sort of.
Applied this patch, got a clean render.

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.

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.

- Stopped daemons.
- Restarted a build in Harbormaster.
- Stepped through the build one stage at a time using `bin/worker execute ...`.

Ref T9252. Currently, Drydock Leases and Resources have several workers:
- Resources: ResourceWorker, ResourceUpdateWorker, ResourceDestroyWorker
- Leases: AllocatorWorker, LeaseWorker, LeaseUpdateWorker, LeaseDestroyWorker
This is kind of a lot of stuff, and it creates some problems.
In particular, leases and resources in early lifecycle phases (pending/allocating/acquiring) can't process commands yet, because that code is only in the "UpdateWorker" classes. If they aren't able to move forward because of a bug, they also can't be released because they can't react to the release command until later in their lifecycle. This creates a soft hang where I have to go wipe stuff out of the database since there's no other way to get rid of it.
Instead, I want leases and resources to be releasable from any (pre-release / pre-destroy) phase of their lifecycle. To support this, all the workers before the "UpdateWorker" need to be able to process commands.
A second, similar issue is that logging and exception handling behaviors are underpowered right now. Elsewhere I began improving this, but ran into issues where all of the workers needed to share very similar exception code. Merging them will make this future change simpler.
This diff fixes this for resources: it merges the Worker, UpdateWorker and DestroyWorker logic into UpdateWorker and throws away the other two workers.

- Instead of making logs a top-level object, make them strictly a sub-object of Blueprints, Resources and Leases. So you go Drydock > Lease > Logs, etc., to get to logs.
- I might restore the "everything" view eventually, but it doesn't interact well with policies and I'm not sure it's very useful. A policy-violating `bin/drydock log` might be cleaner.
- Policy-wise, we always show you that logs exist, we just don't show you log content if it's about something you can't see. This is similar to seeing restricted handles in other applications.
- Instead of just having a message, give logs "type" + "data". This will let logs be more structured and translatable. This is similar to recent changes to Herald which seem to have worked well.

Summary:
Ref T9252. Currently, Harbormaster does this when trying to acquire a working copy:
- Ask for a working copy.
- Yield for 15 seconds.
- Check if we have a working copy yet.
That's OK, but Drydock takes ~1s to acquire a working copy lease if a resource is already available, so we end up doing this:
- T+0: Ask for a working copy.
- T+0: Yield for 15 seconds.
- T+1: Working copy lease activates.
- T+15: Working copy lease is used.
- T+16: Build finishes.
So we end up spending about 2 seconds doing work and 14 seconds sleeping.
One way to fix this would be to fiddle with the yield duration, so we yield for 1, 2, 4, ... seconds or something. This probably isn't a bad idea for longer leases (i.e., wait for 15, 30, 45 ... seconds or similar) but it implies a lot of churn for short leases.
Instead, let tasks "awaken" other tasks when they complete. The "awaken" operation means: if a task is in a yielded state (no failures, no owner, explicitly yielded, future expires time), pretend it only yielded until right now instead of whenever it really yielded to.
Basically, this rewrites history so that even though Harbormaster did a `yield(15)`, we pretend it did a `yield(4)` after we activate the lease if lease activation took 4 seconds.
If this misses, it's fine: we fall back to the normal yield behavior and things move forward normally a few seconds later.
If it hits, we get a more nimble process pretty cleanly.
Test Plan:
- Restarted a build plan (lease working copy + run `ls`) with this patch no-op'd, took about 16 seconds.
- Restarted a build plan with this patch active, took about 1 second.

Summary: Ref T9252. Show the user when a resource or lease has a pending release command in queue.
Test Plan: Released a resource and lease from the web UI. In both cases, saw a "releasing" tag and the action disable.

Summary:
Fixes T6569. This implements an expiry mechanism for Drydock resources which parallels the mechanism for leases.
A few things are missing that we'll probably need in the future:
- An "EXPIRES" command to update the expiration time. This would let resources be permanent while leased, then expire after, say, 24 hours without any leases.
- A callback like `shouldActuallyExpireRightNow()` for resources and leases that lets them decide not to expire at the last second.
- A callback like `didAcquireLease()` for resource blueprints, to parallel `didReleaseLease()`, letting them clear or extend their timer.
However, this stuff would mostly just let us tune behaviors, not really open up new capabilities.
Test Plan: Changed host resources to expire after 60 seconds, leased one, saw it vanish 60 seconds later.
