Previously people were able to send random data to feature type. Now it
is validated.

This PR allows you to gradually lower constraint values, even if they're
above the limits.
It does, however, come with a few caveats because of how Unleash deals
with constraints:
Constraints are just json blobs. They have no IDs or other
distinguishing features. Because of this, we can't compare the current
and previous state of a specific constraint.
What we can do instead, is to allow you to lower the amount of
constraint values if and only if the number of constraints hasn't
changed. In this case, we assume that you also haven't reordered the
constraints (not possible from the UI today). That way, we can compare
constraint values between updated and existing constraints based on
their index in the constraint list.
It's not foolproof, but it's a workaround that you can use. There's a
few edge cases that pop up, but that I don't think it's worth trying to
cover:
Case: If you **both** have too many constraints **and** too many
constraint values
Result: You won't be allowed to lower the amount of constraints as long
as the amount of strategy values is still above the limit.
Workaround: First, lower the amount of constraint values until you're
under the limit and then lower constraints. OR, set the constraint you
want to delete to a constraint that is trivially true (e.g. `currentTime
> yesterday` ). That will essentially take that constraint out of the
equation, achieving the same end result.
Case: You re-order constraints and at least one of them has too many
values
Result: You won't be allowed to (except for in the edge case where the
one with too many values doesn't move or switches places with another
one with the exact same amount of values).
Workaround: We don't need one. The order of constraints has no effect on
the evaluation.
This PR updates the limit validation for constraint numbers on a single
strategy. In cases where you're already above the limit, it allows you
to still update the strategy as long as you don't add any **new**
constraints (that is: the number of constraints doesn't increase).
A discussion point: I've only tested this with unit tests of the method
directly. I haven't tested that the right parameters are passed in from
calling functions. The main reason being that that would involve
updating the fake strategy and feature stores to sync their flag lists
(or just checking that the thrown error isn't a limit exceeded error),
because right now the fake strategy store throws an error when it
doesn't find the flag I want to update.
https://linear.app/unleash/issue/2-2453/validate-patched-data-against-schema
This adds schema validation to patched data, fixing potential issues of
patching data to an invalid state.
This can be easily reproduced by patching a strategy constraints to be
an object (invalid), instead of an array (valid):
```sh
curl -X 'PATCH' \
'http://localhost:4242/api/admin/projects/default/features/test/environments/development/strategies/8cb3fec6-c40a-45f7-8be0-138c5aaa5263' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-d '[
{
"path": "/constraints",
"op": "replace",
"from": "/constraints",
"value": {}
}
]'
```
Unleash will accept this because there's no validation that the patched
data actually looks like a proper strategy, and we'll start seeing
Unleash errors due to the invalid state.
This PR adapts some of our existing logic in the way we handle
validation errors to support any dynamic object. This way we can perform
schema validation with any object and still get the benefits of our
existing validation error handling.
This PR also takes the liberty to expose the full instancePath as
propertyName, instead of only the path's last section. We believe this
has more upsides than downsides, especially now that we support the
validation of any type of object.
This PR adds prometheus metrics for when users attempt to exceed the
limits for a given resource.
The implementation sets up a second function exported from the
ExceedsLimitError file that records metrics and then throws the error.
This could also be a static method on the class, but I'm not sure that'd
be better.
This PR adds a feature flag limit to Unleash. It's set up to be
overridden in Enterprise, where we turn the limit up.
I've also fixed a couple bugs in the fake feature flag store.
This PR adds metrics tracking for:
- "maxConstraintValues": the highest number of constraint values that
are in use
- "maxConstraintsPerStrategy": the highest number of constraints used on
a strategy
It updates the existing feature strategy read model that returns max
metrics for other strategy-related things.
It also moves one test into a more fitting describe block.
This PR is part of #4380 - Remove legacy `/api/feature` endpoint.
## About the changes
### Frontend
- Removes the useFeatures hook
- Removes the part of StrategyView that displays features using this
strategy (not been working since v4.4)
- Removes 2 unused features entries from routes
### Backend
- Removes the /api/admin/features endpoint
- Moves a couple of non-feature related tests (auth etc) to use
/admin/projects endpoint instead
- Removes a test that was directly related to the removed endpoint
- Moves a couple of tests to the projects/features endpoint
- Reworks some tests to fetch features from projects features endpoint
and strategies from project strategies
I've tried to use/add the audit info to all events I could see/find.
This makes this PR necessarily huge, because we do store quite a few
events.
I realise it might not be complete yet, but tests
run green, and I think we now have a pattern to follow for other events.
Via the API you can currently create gradualRollout strategies without
any parameters set, when visiting the UI afterwards, you can edit this,
because the UI reads the parameter list from the database and sees that
some parameters are required, and refuses to accept the data. This PR
adds defaults for gradualRollout strategies created from the API, making
sure gradual rollout strategies always have `rollout`, `groupId` and
`stickiness` set.
Lots of work here, mostly because I didn't want to turn off the
`noImplicitAnyLet` lint. This PR tries its best to type all the untyped
lets biome complained about (Don't ask me how many hours that took or
how many lints that was >200...), which in the future will force test
authors to actually type their global variables setup in `beforeAll`.

## About the changes
Adds the new nullable column created_by_user_id to the data used by
feature-tag-store and feature-tag-service. Also updates openapi schemas.
### What
Adds `createdByUserId` to all events exposed by unleash. In addition
this PR updates all tests and usages of the methods in this codebase to
include the required number.
Instead of throwing an error when the project doesn't exist, we say that
the names are valid, because we have nothing to say that they're not.
Presumably there is already something in place to prevent you from
importing into a non-existent project.
