Summary:
Ref T11954. This is kind of complex and I'm not sure I want to actually land it, but it gives us a fairly good improvement for clustered repositories so I'm leaning toward moving forward.
When we make (or receive) clustered repository requests, we must first load a bunch of stuff out of Almanac to figure out where to send the request (or if we can handle the request ourselves).
This involves several round trip queries into Almanac (service, device, interfaces, bindings, properties) and generally is fairly slow/expensive. The actual data we get out of it is just a list of URIs.
Caching this would be very easy, except that invalidating the cache is difficult, since editing any binding, property, interface, or device may invalidate the cache for indirectly connected services and repositories.
To address this, introduce `PhabricatorCacheEngine`, which is an extensible engine like `PhabricatorDestructionEngine` for propagating cache updates. It has two modes:
- Discover linked objects (that is: find related objects which may need to have caches invalidated).
- Invalidate caches (that is: nuke any caches which need to be nuked).
Both modes are extensible, so third-party code can build repository-dependent caches or whatever. This may be overkill but even if Almanac is the only thing we use it for it feels like a fairly clean solution to the problem.
With `CacheEngine`, make any edit to Almanac stuff propagate up to the Service, and then from the Service to any linked Repositories.
Once we hit repositories, invalidate their caches when Almanac changes.
Test Plan:
- Observed a 20-30ms performance improvement with `ab -n 100`.
- (The main page making Conduit calls also gets a performance improvement, although that's a little trickier to measure directly.)
- Added debugging code to the cache engine stuff to observe the linking and invalidation phases.
- Made invalidation throw; verified that editing properties, bindings, etc, properly invalidates the cache of any indirectly linked repositories.

Summary:
Ref T10917. Currently, when you delete an SSH key, we really truly delete it forever.
This isn't very consistent with other applications, but we built this stuff a long time ago before we were as rigorous about retaining data and making it auditable.
In partiular, destroying data isn't good for auditing after security issues, since it means we can't show you logs of any changes an attacker might have made to your keys.
To prepare to improve this, stop destoying data. This will allow later changes to become transaction-oriented and show normal transaction logs.
The tricky part here is that we have a `UNIQUE KEY` on the public key part of the key.
Instead, I changed this to `UNIQUE (key, isActive)`, where `isActive` is a nullable boolean column. This works because MySQL does not enforce "unique" if part of the key is `NULL`.
So you can't have two rows with `("A", 1)`, but you can have as many rows as you want with `("A", null)`. This lets us keep the "each key may only be active for one user/object" rule without requiring us to delete any data.
Test Plan:
- Ran schema changes.
- Viewed public keys.
- Tried to add a duplicate key, got rejected (already associated with another object).
- Deleted SSH key.
- Verified that the key was no longer actually deleted from the database, just marked inactive (in future changes, I'll update the UI to be more clear about this).
- Uploaded a new copy of the same public key, worked fine (no duplicate key rejection).
- Tried to upload yet another copy, got rejected.
- Generated a new keypair.
- Tried to upload a duplicate to an Almanac device, got rejected.
- Generated a new pair for a device.

Summary:
Ref T4292. Currently, we hold one big lock around the whole `bin/repository update` workflow.
When running multiple daemons on different hosts, this lock can end up being contentious. In particular, we'll hold it during `git fetch` on every host globally, even though it's only useful to hold it locally per-device (that is, it's fine/good/expected if `repo001` and `repo002` happen to be fetching from a repository they are observing at the same time).
Instead, split it into two locks:
- One lock is scoped to the current device, and held during pull (usually `git fetch`). This just keeps multiple daemons accidentally running on the same host from making a mess when trying to initialize or update a working copy.
- One lock is scoped globally, and held during discovery. This makes sure daemons on different hosts don't step on each other when updating the database.
If we fail to acquire either lock, assume some other process is legitimately doing the work and bail more quietly instead of fataling. In approximately 100% of cases where users have hit this lock contention, that was the case: some other daemon was running somewhere doing the work and the error didn't actually represent an issue.
If there's an actual problem, we still raise a diagnostically useful message if you run `bin/repository update` manually, so there are still tools to figure out that something is hung or whatever.
Test Plan:
- Ran `bin/repository update`, `pull`, `discover`.
- Added `sleep(5)`, forced processes to contend, got lock exceptions and graceful exit with diagnostic message.

- Today, against users in the Phacility cluster accidentally breaking their own instances.
- In the future, against attackers compromising administrative accounts and adding a new "cluster database" which points at hardware they control.
The way this works right now is really complicated: there's a global "can create cluster services" setting, and then separate per-service and per-device locks.
Instead, change "Can Create Cluster Services" into "Can Manage Cluster Services". Require this permission (in addition to normal permissions) to edit or create any cluster service.
This permission can be locked to "No One" via config (as we do in the Phacility cluster) so we only need this one simple setting.
There's also zero reason to individually lock //some// of the cluster services.
Also improve extended policy errors.
The UI here is still a little heavy-handed, but should be good enough for the moment.
Test Plan:
- Ran migrations.
- Verified that cluster services and bindings reported that they belonged to the cluster.
- Edited a cluster binding.
- Verified that the bound device was marked as a cluster device
- Moved a cluster binding, verified the old device was unmarked as a cluster device.

After the next diff, if you try to create `repo003.phacility.net`, but the namespace `phacility.net` already exists and you don't have permission to edit it, you'll be asked to choose a different name.

- 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.
