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.

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.

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.

- 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.

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.

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.

The ~only thing that should ever wait for leases in modern code is `bin/drydock lease`, and it's fine for it to just sit there sleeping, so this just does that.

(I didn't chase down a detailed reproduction scenario for this since inspection of the code makes it clear that there are no meaningful locks or mechanisms preventing this.)
Instead, add a Harbormaster-style command queue to resources and leases. When something wants to do a release, it adds a command to the queue and schedules a worker. The workers acquire a lock, then try to consume commands from the queue.
This guarantees that only one process is responsible for writes to active resource/leases.
This is the last major step to giving resources and leases a single writer during all states:
- Resource, Unsaved: AllocatorWorker
- Resource, Pending: ResourceWorker (Possible rename to "Allocated?")
- Resource, Open: This diff, ResourceUpdateWorker. (Likely rename to "Active").
- Resource, Closed/Broken: Future destruction worker. (Likely rename to "Released" / "Broken"; maybe remove "Broken").
- Resource, Destroyed: No writes.
- Lease, Unsaved: Whatever wants the lease.
- Lease, Pending: AllocatorWorker
- Lease, Acquired: LeaseWorker
- Lease, Active: This diff, LeaseUpdateWorker.
- Lease, Released/Broken: Future destruction worker (Maybe remove "Broken"?)
- Lease, Expired: No writes. (Likely rename to "Destroyed").
In most phases, we can already guarantee that there is a single writer without doing any extra work. This is more complicated in the "Active" case because the release buttons on the web UI, the release tools on the CLI, the lease requestor itself, the garbage collector, and any other release process cleaning up related objects may try to effect a release. All of these could race one another (and, in many cases, race other processes from other phases because all of these get to act immediately) as this code is currently written. Using a queue here lets us make sure there's only a single writer in this phase.
One thing which is notable is that whatever acquires a lease **can not write to it**! It is never the writer once it queues the lease for activation. It can not write to any resources, either. And, likewise, Blueprints can not write to resources while acquiring or releasing leases.
We may need to provide a mechinism so that blueprints and/or resource/lease holders get to attach some storage to resources/leases for bookkeeping. For example, a blueprint might need to keep some kind of cache on a resource to help it manage state. But I think we can cross that bridge when we come to it, and nothing else would need to write to this storage so it's technically straightforward to introduce such a mechanism if we need one.
Test Plan:
- Viewed buttons in web UI, checked enabled/disabled states.
- Clicked the buttons.
- Saw commands show up in the command queue.
- Saw some daemon stuff get scheduled.
- Ran CLI tools, saw commands get consumed and resources/leases release.

Summary:
See discussion in D10304. There's a lot of context there, but the general idea is:
- Blueprints should manage locks in a granular way during the actual allocation/acquisition phase.
- Optimistic "slot locks" might a pretty good primitive to make that easy to implement and reason about in most cases.
The way these locks work is that you just pick some name for the lock (like the PHID of a resource) and say that it needs to be acquired for the allocation/acquisition to work:
```
...
->needSlotLock("mylock(PHID-XYZQ-...)")
...
```
When you fire off the acquisition or allocation, it fails unless it could acquire the slot with that name. This is really simple (no explicit lock management) and a pretty good fit for most of the locking that blueprints and leases need to do.
If you need to do limit-based locks (e.g., maximum of 3 locks) you could acquire a lock like this:
```
mylock(whatever).slot(2)
```
Blueprints generally only contend with themselves, so it's normally OK for them to pick whatever strategy works best for them in naming locks.
This may not work as well if you have a huge number of slots (e.g., 100TB you want to give out in 1MB chunks), or other complex needs for locks (like you have to synchronize access to some external resource), but slot locks don't need to be the only mechanism that blueprints use. If they run into a problem that slot locks aren't a good fit for, they can use something else instead. For now, slot locks seem like a good fit for the problems we currently face and most of the problems I anticipate facing.
(The release workflows have other race issues which I'm not addressing here. They work fine if nothing races, but aren't race-safe.)
Test Plan:
To create a race where the same binding is allocated as a resource twice:
- Add `sleep(10)` near the beginning of `allocateResource()`, after the free bindings are loaded but before resources are allocated.
- (Comment out slot lock acquisition if you have this patch.)
- Run `bin/drydock lease ...` in two windows, within 10 seconds of one another.
This will reliably double-allocate the binding because both blueprints see a view of the world where the binding is free.
To verify the lock works, un-comment it (or apply this patch) and run the same test again. Now, the lock fails in one process and only one resource is allocated.

Summary:
Ref T9253. Broadly, this realigns Allocator behavior to be more consistent and straightforward and amenable to intended future changes.
This attempts to make language more consistent: resources are "allocated" and leases are "acquired".
This prepares for (but does not implement) optimistic "slot locking", as discussed in D10304. Although I suspect some blueprints will need to perform other locking eventually, this does feel like a good fit for most of the locking blueprints need to do.
In particular, I've made the blueprint operations on `$resource` and `$lease` objects more purposeful: they need to invoke an activator on the appropriate object to be implemented correctly. Before they invoke this activator method, they configure the object. In a future diff, this configuration will include specifying slot locks that the lease or resource must acquire. So the API will be something like:
$lease
->setActivateWhenAcquired(true)
->needSlotLock('x')
->needSlotLock('y')
->acquireOnResource($resource);
In the common case where slot locks are a good fit, I think this should make correct blueprint implementation very straightforward.
This prepares for (but does not implement) resources and leases which need significant setup steps. I've basically carved out two modes:
- The "activate immediately" mode, as here, immediately opens the resource or activates the lease. This is appropriate if little or no setup is required. I expect many leases to operate in this mode, although I expect many resources will operate in the other mode.
- The "allocate now, activate later" mode, which is not fully implemented yet. This will queue setup workers when the allocator exits. Overall, this will work very similarly to Harbormaster.
- This new structure makes it acceptable for blueprints to sleep as long as they want during resource allocation and lease acquisition, so long as they are not waiting on anything which needs to be completed by the queue. Putting a `sleep(15 * 60)` in your EC2Blueprint to wait for EC2 to bring a machine up will perform worse than using delayed activation, but won't deadlock the queue or block any locks.
Overall, this flow is more similar to Harbormaster's flow. Having consistency between Harbormaster's model and Drydock's model is good, and I think Harbormaster's model is also simply much better than Drydock's (what exists today in Drydock was implemented a long time ago, and we had more support and infrastructure by the time Harbormaster was implemented, as well as a more clearly defined problem).
The particular strength of Harbormaster is that objects always (or almost always, at least) have a single, clearly defined writer. Ensuring objects have only one writer prevents races and makes reasoning about everything easier.
Drydock does not currently have a clearly defined single writer, but this moves us in that direction. We'll probably need more primitives eventually to flesh this out, like Harbormaster's command queue for messaging objects which you can't write to.
This blueprint was originally implemented in D13843. This makes a few changes to the blueprint itself:
- A bunch of code from that (e.g., interfaces) doesn't exist yet.
- I let the blueprint have multiple services. This simplifies the code a little and seems like it costs us nothing.
This also removes `bin/drydock create-resource`, which no longer makes sense to expose. It won't get locking, leasing, etc., correct, and can not be made correct.
NOTE: This technically works but doesn't do anything useful yet.
Test Plan: Used `bin/drydock lease --type host` to acquire leases against these blueprints.

- Provide a StandardCustomField for an arbitrary datasource.
- Adjust the AlmanacServiceDatasource to allow filtering by service class.
This implementation is substantially the same as the one in D13843, with some adjustments:
- I lifted most of the code in the `Users` standard custom field into a new `Tokenizer` standard custom field.
- The `Users` and `Datasource` custom fields now extend the `Tokenizer` custom field and can share most of the code it uses.
- I exposed this field fully as a configurable field. I don't think anyone will ever use it, but this generality costs us nearly nothing and improves consistency.
- The code in D13843 didn't actually pass the parameters over the wire, since the object that responds to the request is not the same object that renders the field. Use the "parameters" mechanism in datasources to get things passed over the wire.

- Created a custom "users" field in Maniphest and made sure it still wokred.

Summary:
Ref T1806. Ref T7173. Context here is that I want to fix "you can not log in to this instance" being a confusing mess with an opaque error. To do this without hacks, I want to:
- clean up some exception handling behavior (this diff);
- modularize exception handling (next diff);
- replace confusing, over-general exceptions with tailored ones in the Phacility cluster, using the new modular stuff.
This cleans up an awkward "AphrontUsageException" which does some weird stuff right now. In particular, it is extensible and extended in one place in Diffusion, but that extension is meaningless.
Realign this as "AphrontMalformedRequestException", which is a better description of what it is and does: raises errors before we can get as far as normal routing and site handling.
Test Plan: Hit some of these exceptions, saw the expected "abandon all hope" error page.

Ref T1806. Ref T5752. Currently, `handleRequest()` needs to return an `AphrontResponse`, but sometimes it's really convenient to return some other object, like a Dialog, and let that convert into a response elsewhere.
Formalize this and clean up some of the existing hacks for it so there's less custom/magical code in Phabricator-specific classes and more general code in Aphront classes.
More broadly, I want to clean up T5752 before pursuing T9132, since I'm generally happy with how `SearchEngine` works except for how it interacts with side navs / application menus. I want to fix that first so a new Editor (which will have a lot in common with SearchEngine in terms of how controllers interact with it) doesn't make the problem twice as bad.

Fixes T9268. Currently, we try to match any string like "a2f313f1" as a commit/revision, so short hashes will get picked up.
However, we don't require a word boundary or terminal after the match, so for input like "aaa...aaaaz" the engine can get stuck trying to split the string into sub-matches.
That is, in the original case, the input "aaaz" had valid matches against `[rA-Z0-9a-f]+` up to "z" of:
aaa
aa a
a aa
a a a
All of these will fail once it hits "z", but it has to try them all. This complexity is explosive with longer strings.
Instead, require a word boundary or EOL after the match, so this is the only valid match:
aaa
Then the engine sees the "z", says "nope, no match" and doesn't have to backtrack across all possible combinations.
Test Plan: Added a failing unit test, applied patch, clean test.

Summary:
Ref T8672. Ref T9187. Root issue in at least one case is:
- User makes a commit including a file with some non-UTF8 text (say, a Japanese file full of Shift-JIS).
- We pass the file to the TransactionEditor so it can inline or attach the patch if the server is configured for these things.
- When inlining patches, we convert them to UTF8 before inlining. We must do this since the rest of the mail is UTF8.
- When attaching patches, we send them in the original encoding (as file attachments). This is correct, and means we need to give the worker the raw patch in whatever encoding it was originally in: we can't just convert it to utf8 earlier, or we'd attach the wrong patch in some cases.
- TransactionEditor does its thing (e.g., creates the commit), then gets ready to send mail about whatever it did.
- The publishing work now happens in the daemon queue, so we prepare to queue a PublishWorker and pass it the patch (with some other data).
- When we queue workers, we serialize the state data with JSON.
So far, so good. But this is where things go wrong:
- JSON can't encode binary data, and can't encode Shift-JIS. The encoding silently fails and we ignore it.
Then we get to the worker, and things go wrong-er:
- Since the data is bad, we fatal. This isn't a permanent failure, so we continue retrying the task indefinitely.
This applies several fixes:
# When queueing tasks, fail loudly when JSON encoding fails.
# In the worker, fail permanently when data can't be decoded.
# Allow Editors to specify that some of their data is binary and needs special handling.
This is fairly messy, but some simpler alternatives don't seem like good ways forward:
- We can't convert to UTF8 earlier, because we need the original raw patch when adding it as an attachment.
- We could encode //only// this field, but I suspect some other fields will also need attention, so that adding a mechanism will be worthwhile. In particular, I suspect filenames //may// be causing a similar problem in some cases.
- We could convert task data to always use a serialize()-based binary safe encoding, but this is a larger change and I think it's correct that things are UTF8 by default, even if it makes a bit of a mess. I'd rather have an explicit mess like this than a lot of binary data floating around.
The change to make `LiskDAO` will almost certainly catch some other problems too, so I'm going to hold this until after `stable` is cut. These problems were existing problems (i.e., the code was previously breaking or destroying data) so it's definitely correct to catch them, but this will make the problems much more obvious/urgent than they previously were.
Test Plan:
- Created a commit with a bunch of Shift-JIS stuff in a file.
- Tried to import it.
Prior to patch:
- Broken PublishWorker with distant, irrelevant error message.
With patch partially applied (only new error checking):
- Explicit, local error message about bad key in serialized data.
With patch fully applied:
- Import went fine and mail generated.
