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.

1. I downloaded Mercurial 2.6.2 source and run `make local` which will only compile it to work from its own directory (`/opt/mercurial-2.6.2`)
2. I linked `/usr/local/bin/hg -> /opt/mercurial-2.6.2/hg` (there's also a `/usr/bin/hg` which is a link to `/usr/local/bin/hg`)
3. I navigated to my home directory and verify that `hg --version` returns 2.6.2.
4. I restarted phabricator services (probably unnecessary).

1. I verified that `/usr/local/bin/hg` referred to version 2.6
2. I ran the same conduit call from the conduit application
3. I verified that `http://192.168.0.133/multimeter/?type=2&group=label` incremented values for `bin.hg locate`.

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.

# 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.

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.

Summary:
Ref T9252. See companion change in D14211. This does the same thing for leases.
Particularly, most of the TODOs about error handling can just be removed because they'll do the right things by default now.
This and D14211 also move slot lock release to after resource destruction. This feels cleaner than trying to release early at release/break.
Test Plan: Restarted a Harbormaster build, got a clean build result. This needs more vetting but I'll clean up any issues as I hit them.

Summary:
Ref T9252. Currently, error handling behavior isn't great and a lot of errors aren't dealt with properly. Try to improve this by making default behaviors better:
- Yields, slot lock exceptions, and aggregate or proxy exceptions containing an excpetion of these types turn into yields.
- All other exceptions are considered permanent failures. They break the resource and
This feels a little bit "magical" but I want to try to get the default behaviors to align reasonably well with expectations so that blueprints mostly don't need to have a ton of error handling. This will probably need at least some refinement down the road, but it's a reasonable rule for all exception/error conditions we currently have.
Test Plan: I did a clean build, but haven't vetted this super thoroughly. Next diff will do the same thing to leases, then I'll work on stabilizing this code better.

Summary:
Ref T9252. This is the same as D14201, but for lease stuff instead of resource stuff.
This one is a little heavier but still feels pretty reasonable to me at the end of the day (worker is <1K lines and has a ton of comment stuff).
Also fixes a few random bugs I hit in the task queue.
Test Plan:
- Restarted some Harbormaster builds, saw them go through cleanly.
- Released pre-activation resources/leases.
- Probably still kinda buggy but I'll iron the details out over time.
Logs are starting to look somewhat plausible:

Summary:
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.
Test Plan: Nothing substantive yet, see next diff. I'll do the same thing for Leases, then test both more thoroughly.

Summary:
Ref T9252. Drydock logs are almost exclusively useful as a diagnostic tool for debugging immediate problems, so GC them fairly aggressively.
(I expect 99% of the usefulness of these logs to be within the first 24 hours, basically "why isn't my thing working". I can't really think of any cases where having old logs would be useful.)
Test Plan:
- Ran GC, saw it hit the log table (with no effect).
- Changed TTL from 30 days to 30 seconds, ran GC, saw it wipe recent logs.

Summary:
Ref T9252. Several general changes here:
- Moves logs to use PHIDs instead of IDs. This generally improves flexibility (for example, it's a lot easier to render handles).
- Adds `blueprintPHID` to logs. Although you can usually figure this out from the leasePHID or resourcePHID, it lets us query relevant logs on Blueprint views.
- 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.
Test Plan:
Added some placeholder log writes, viewed those logs in the UI.
