## About the changes
This enables us to use names instead of permission ids across all our
APIs at the computational cost of searching for the ids in the DB but
improving the API user experience
## Open topics
We're using methods that are test-only and circumvent our business
logic. This makes our test to rely on assumptions that are not always
true because these assumptions are not validated frequently.
i.e. We are expecting that after removing a permission it's no longer
there, but to test this, the permission has to be there before:
78273e4ff3/src/test/e2e/services/access-service.e2e.test.ts (L367-L375)
But it seems that's not the case.
We'll look into improving this later.
## About the changes
- `getActiveUsers` is using multiple stores, so it is refactored into
read-model
- Refactored Instance stats service into `features` to co-locate related
code
Closes https://linear.app/unleash/issue/UNL-230/active-users-prometheus
### Important files
`src/lib/features/instance-stats/getActiveUsers.ts`
## Discussion points
`getActiveUsers` is coded less _class-based_ then previous similar
read-models. In one file instead of 3 (read-model interface, fake read
model, sql read model). I find types and functions way more readable,
but I'm ready to refactor it to interfaces and classes if consistency is
more important.
Seems like when 2 pods are trying to POST lastSeen metrics, the db gets
into a deadlock state.
This is an attempt to fix the deadlock by sorting the toggleNames before
the update.
The hypothesis is that sorted toggle names will reduce the chance of
working on the same row at the same exact time

This change makes it so that you can save flag naming data on project
creation.
There was a mismatch between flattened and nested data in the creation
endpoint. Likely because we went back and forth a bit when we created
the feature originally.
This PR adds a feature naming pattern description to the project form.
It's rendered as a multi-line input field. The description is also
stored in the db.
This adapts most of @andreas-unleash's PR #4599 with some minor changes
(using description instead of prompt). Actually displaying this data to
the users will come in a later PR.

In a new fresh Unleash instance with cache enabled this can cause
feature toggles to never get updated.
We saw in our client that the ETag was ETag: "60e35fba:null" Which
looked incorrect for us.
I also did manual testing and if the andWhere had a value of largerThan
higher than whatever the id was then we would get back { max: null }.
This should fix that issue.
## About the changes
We are losing some events because of not having "created by" which is
required by a constraint in the DB. One scenario where this can happen
is with the default user admin, because it doesn't have a username or an
email (unless configured by the administrator).
Our code makes assumptions on the existence of one of these 2 attributes
(e.g.
248118af7c/src/lib/services/user-service.ts (L220-L222)).
Event lost metrics:

## Discussion points
The solution proposed here is falling back to a default value. I've
chosen `"admin"` because it covers one of the use cases, but it can also
be `"system"` mimicking
248118af7c/src/lib/services/user-service.ts (L32)
which is used as a default, or `"unknown"` which is sometimes used as a
default:
248118af7c/src/lib/services/project-service.ts (L57)
Anyway, I believe it's better not to lose the event rather than be
accurate with the "created by" that can be fixed later
This PR does **one** thing:
it changes the events for potentially stale to:
- Only being emitted when potentially stale gets turned on
- In doing so, it also simplifies the event that's getting emitted,
removing the `data` property.
- The event is also renamed to better match the existing
`feature-stale-on` and `...-off` events.
The addon listening was broken out into a separate PR (#4279)
## Old description
This change lets all addons listen for events when features get marked
or unmarked as potentially stale.
### Discussion
#### All addons?
Should this be available to all addons? I can't see a reason why it
shouldn't be available to all addons, but I might be missing
something.
**Update**: spoke to a couple people. Can see no reason why this isn't
okay.
#### Should it be behind a flag?
The feature is still behind a flag, but the event type is not. Should
we gate the event being available until we actually emit the event?
That would require some more code, but could yield less potential
confusion.
Open to hearing your thoughts.
This PR updates the feature type service by adding a new
`updateLifetime` method. This method handles the connection between the
API (#4256) and the store (#4252).
I've also added some new e2e tests to ensure that the API behaves as
expected.

This PR adds updates the potentially stale status change events whenever
the potentially stale update function is run.
No events are emitted yet. While the emission is only a few lines of
code, I'd like to do that in a separate PR so that we can give it the
attention it deserves in the form of tests, etc.
This PR also moves the potentially stale update functionality from the
`update` method to only being done in the
`updatePotentiallyStaleFeatures` method. This keeps all functionality
related to marking `potentiallyStale` in one place.
The emission implementation was removed in
4fb7cbde03
## The update queries
While it would be possible to do the state updates in a single query
instead of three separate ones, wrangling this into knex proved to be
troublesome (and would also probably be harder to understand and reason
about). The current solution uses three smaller queries (one select, two
updates), as Jaanus suggested in a private slack thread.
This PR lays most of the groundwork required for emitting events when
features are marked as potentially stale by Unleash. It does **not**
emit any events just yet. The summary is:
- periodically look for features that are potentially stale and mark
them (set to run every 10 seconds for now; can be changed)
- when features are updated, if the update data contains changes to the
feature's type or createdAt date, also update the potentially stale
status.
It is currently about 220 lines of tests and about 100 lines of
application code (primarily db migration and two new methods on the
IFeatureToggleStore interface).
The reason I wanted to put this into a single PR (instead of just the db
migration, then just the potentially stale marking, then the update
logic) is:
If users get the db migration first, but not the rest of the update
logic until the events are fired, then they could get a bunch of new
events for features that should have been marked as potentially stale
several days/weeks/months ago. That seemed undesirable to me, so I
decided to bunch those changes together. Of course, I'd be happy to
break it into smaller parts.
## Rules
A toggle will be marked as potentially stale iff:
- it is not already stale
- its createdAt date is older than its feature type's expected lifetime
would dictate
## Migration
The migration adds a new `potentially_stale` column to the features
table and sets this to true for any toggles that have exceeded their
expected lifetime and that have not already been marked as `stale`.
## Discussion
### The `currentTime` parameter of `markPotentiallyStaleFeatures`
The `markPotentiallyStaleFetaures` method takes an optional
`currentTime` parameter. This was added to make it easier to test (so
you can test "into the future"), but it's not used in the application.
We can rewrite the tests to instead update feature toggles manually, but
that wouldn't test the actual marking method. Happy to discuss.
This PR fixes an issue where events generated during a db transaction
would get published before the transaction was complete. This caused
errors in some of our services that expected the data to be stored
before the transaction had been commited. Refer to [linear issue
1-1049](https://linear.app/unleash/issue/1-1049/event-emitter-should-emit-events-after-db-transaction-is-commited-not)
for more info.
Fixes 1-1049.
## Changes
The most important change here is that the `eventStore` no longer emits
events when they happen (because that can be in the middle of a
transaction). Instead, events are stored with a new `announced` column.
The new event announcer service runs on a schedule (every second) and
publishes any new events that have not been published.
Parts of the code have largely been lifted from the
`client-application-store`, which uses a similar logic.
I have kept the emitting of the event within the event store because a
lot of other services listen to events from this store, so removing that
would require a large rewrite. It's something we could look into down
the line, but it seems like too much of a change to do right now.
## Discussion
### Terminology:
Published vs announced? We should settle on one or the other. Announced
is consistent with the client-application store, but published sounds
more fitting for events.
### Publishing and marking events as published
The current implementation fetches all events that haven't been marked
as announced, sets them as announced, and then emits them. It's possible
that Unleash would crash in the interim or something else might happen,
causing the events not to get published. Maybe it would make sense to
just fetch the events and only mark them as published after the
announcement? On the other hand, that might get us into other problems.
Any thoughts on this would be much appreciated.
### What
This PR adds documentation for our endpoints that are covered by our
"Events" tag. It also adds a type for all valid events, and then uses
this as valid values for type argument.
