4b43667086 Introduce PHUIRemarkupView, a sane way to work with Remarkup
Summary:
Fixes T9273. Remarkup has reasonably good fundamentals but the API is a giant pain to work with.

Provide a `PHUIRemarkupView` to make it easier. This object is way simpler to use by default.

It's not currently as powerful, but we can expand the power level later by adding more setters.

Eventually I'd expect to replace `PhabricatorRemarkupInterface` and `PhabricatorMarkupOneOff` with this, but no rush on those.

I converted a few callsites as a sanity check that it works OK.

Test Plan:
- Viewed remarkup in Passphrase.
- Viewed remarkup in Badges.
- Viewed a Conduit method.

ac7edf54af Fix bad counting in SQL when enforcing Drydock allocator soft limits
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.

083a321dad Fix an issue where newly created Drydock resources could be improperly acquired
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.

43bee4562c If the stars align, make "Land Revision" kind of work
Summary:
Ref T182. If 35 other things are configured completely correctly, make it remotely possible that this button may do something approximating the thing that the user wanted.

This primarily fleshes out the idea that "operations" (like landing, merging or cherry-picking) can have some beahavior, and when we run an operation we do whatever that behavior is instead of just running `git show`.

Broadly, this isn't too terrible because Drydock seems like it actually works properly for the most part (???!?!).

Ref T182. This doesn't do anything interesting yet and is mostly scaffolding, but here's roughly the workflow. From previous revision, you can configure "Repository Automation" for a repository:

{F875741}

If it's configured, a new "Land Revision" button shows up:

{F875743}

Once you click it you get a big warning dialog that it won't work, and then this shows up at the top of the revision (completely temporary/placeholder UI, some day a nice progress bar or whatever):

{F875747}

If you're lucky, the operation eventually sort of works:

{F875750}

It only runs `git show` right now, doesn't actually do any writes or anything.

Test Plan:
  - Clicked "Land Revision".
  - Watched `phd debug task`.
  - Saw it log `git show` to output.
  - Verified operation success in UI (by fiddling URL, no way to get there normally yet).

812c41a18a Conditionally use hg files vs. hg locate depending on version of Mercurial
Summary:
In Mercurial 3.2 the `locate` command was deprecated in favor of `files` command. This change updates the DiffusionLowLevelMercurialPathsQuery command to conditionally use `locate` or `files` based on the version of Mercurial used.

Closes T7375

Test Plan:
My test/develop Phabricator instance is setup to run Mercurial 3.5.1.

The test procedure to verify valid file listings are being returned:
 1. I navigated to `http://192.168.0.133/conduit/method/diffusion.querypaths/`
 2. I populated the following fields:
  - path: `"/"`
  - commit: `"d721d5b57fc9ef72e47ff9d4e0c583d74a46590c"`
  - callsign: `"HGTEST"`
 3. I submitted request and verified that result contained all files in the repository:
```
{
  "0": "README",
  "1": "alpha/beta/trifle",
  "2": "test/Chupacabra.cow",
  "3": "test/socket.ks"
}
```

I repeated the above steps after setting up Mercurial 2.6.2, which I installed in the following manner:
 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).

With the Multimeter application active
 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`.
 4. I swapped out mercurial versions for 3.5.1
 5. I ran the same conduit call from the conduit application
 6. I verified that `http://192.168.0.133/multimeter/?type=2&group=label` incremented values for `bin.hg files`

  - Then, you 404, even though this tag is reasonably equivalent to the real project tag and could be redirected. Add a fallback to lookup, resolve, and redirect if we can find a hit for the tag.

This also fixes stuff like `/tag/AA_BB/`.

1bdf225354 Use Drydock authorizations when acquiring leases
Summary:
Ref T9519. When acquiring leases on resources:

  - Only consider resources created by authorized blueprints.
  - Only consider authorized blueprints when creating new resources.
  - Fail with a tailored error if no blueprints are allowed.
  - Fail with a tailored error if missing authorizations are causing acquisition failure.

One somewhat-substantial issue with this is that it's pretty hard to figure out from the Harbormaster side. Specifically, the Build step UI does not show field value anywhere, so the presence of unapproved blueprints is not communicated. This is much more clear in Drydock. I'll plan to address this in future changes to Harbormaster, since there are other related/similar issues anyway.

2f6d3119f5 Rough cut of "Blueprint Authorizations"
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:
If Mercurial 3.4+ is used to host repositories in Phabricator, any clients using 3.5+ will receive an exception after the bundle is pushed up. Clients will also fail to update phases for changesets pushed up.

Before directly responding to mercurial clients with all capabilities, this change filters out the 'bundle2' capability so the client negotiates using a legacy bundle wire format instead.

Test Plan:
Server: Mercurial 3.5
Client: Mercurial 3.4

Test with both HTTP and SSH protocols:
1. Create a local commit on client
2. Push commit to server
3. Verify the client emits something like:
```

remote: adding manifests
remote: adding file changes
remote: added 1 changesets with 1 changes to 1 files

2a355d8548 Make Diffusion "Last Modified" rendering less fragile
Summary:
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.

ee937e99fb Fix unbounded expansion of allocating resource pool
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.

b2e89a9e48 Fix several error handling issues with Subversion commits in Diffusion
Summary:
Ref T9513. I checked this briefly but didn't do a very thorough job of it.

  - Don't try to query merges for Subversion, since it doesn't support them.
  - Fix up "existsquery" to work properly (and efficiently) for both hosted and imported repositories.
  - Fix up "parentsquery" to have similar behavior on invalid commits to other VCSes (throw an exception).

Test Plan:
  - No more merges warning on SVN.
  - Hosted SVN gets the right exists result now.
  - Visiting "r23980283789287" now 404's instead of "not parsed yet".

de2bbfef7d Allow PhabricatorWorker->queueTask() to take full $options
Summary:
Ref T9252. Currently, `queueTask()` accepts `$priority` as its third argument. Allow it to take a full range of `$options` instead. This API just never got updated after we expanded avialable options.

Arguably this whole API should be some kind of "TaskQueueRequest" object but I'll leave that for another day.

Test Plan:
  - Grepped for `queueTask()` and verified no other callsites are affected by this API change.
  - Ran some daemons.
  - See also next diff.

4cf1270ecd In Harbormaster, make sure artifacts are destroyed even if a build is aborted
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.

  - 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.

d4a0b1c870 Remove names from Drydock resources
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.

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.

e589d15231 Improve error and exception handling for Drydock resources
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.
