Adds a killswitch called "filterExistingFlagNames". When enabled it will
filter out reported SDK metrics and remove all reported metrics for
names that does not match an exiting feature flag in Unleash.
This have proven critical in the rare case of an SDK that start sending
random flag-names back to unleash, and thus filling up the database. At
some point the database will start slowing down due to the noisy data.
In order to not resolve the flagNames all the time we have added a small
cache (10s) for feature flag names. This gives a small delay (10s) from
flag is created until we start allow metrics for the flag when
kill-switch is enabled. We should probably listen to the event-stream
and use that invalidate the cache when a flag is created.
## About the changes
Validations in the constructor were executed on the way out (i.e. when
reading users). Instead we should validate when we insert the users.
We're also relaxing the email validation to support top domain emails
(e.g. `...@jp`)
This is implementing the segments events for delta API. Previous version
of delta API, we were just sending all of the segments. Now we will have
`segment-updated` and `segment-removed `events coming to SDK.
This PR sets up the application to accept a value from a variant we
control to set the font size of the application on a global level. If it
fails, the value falls back to the previously set CSS value.
Add new methods to the store behind data usage metrics that accept date
ranges instead of a single month. The old data collection methods
re-route to the new ones instead, so the new methods are tested
implicitly.
Also deprecates the new endpoint that's not in use anywhere except in an
unused service method in Enterprise yet.
## Discussion point:
Accepts from and to params as dates for type safety. You can send unparseable strings, but if you send a date object, you know it'll work.
Leaves the use of the old method in `src/lib/features/instance-stats/instance-stats-service.ts` to keep changes small.
We are changing how the Delta API works, as discussed:
1. We have removed the `updated` and `removed` arrays and now keep
everything in the `events` array.
2. We decided to keep the hydration cache separate from the events array
internally. Since the hydration cache has a special structure and may
contain not just one feature but potentially 1,000 features, it behaved
differently, requiring a lot of special logic to handle it.
3. Implemented `nameprefix` filtering, which we were missing before.
Things still to implement:
1. Segment hydration and updates to it.
Add support for querying the traffic data usage store for the aggregated data for an arbitrary number of months back.
Adds a new `getTrafficDataForMonthRange(monthsBack: number)` method to the store that aggregates data on a monthly basis by status code and traffic group. Returns a new type with month data instead of day data.
This PR implements a first version of the new month/range picker for the
data usage graphs. It's minimally hooked up to the existing
functionality to not take anything away.
This primary purpose of this PR is to get the design and interaction out
on sandbox so that UX can have a look and we can make adjustments.
As such, there are a few things in the code that we'll want to clean up
before removing the flag later:
- for faster iteration, I've used a lot of CSS nesting and element
selectors. this isn't usually how we do it here, so we'll probably want
to extract into styled components later
- there is a temporary override of the value in the period selector so
that you can select ranges. It won't affect the chart state, but it
affects the selector state. Again, this lets you see how it acts and
works.
- I've added a `NewHeader` component because the existing setup smushed
the selector (it's a MUI grid setup, which isn't very flexible). I don't
know what we want to do with this in the end, but the existing chart
*does* have some problems when you resize your window, at least
(although this is likely due to the chart, and can be solved in the same
way that we did for the personal dashboards).
Currently, every time you archived feature, it created
feature-dependencies-removed event.
This PR adds a check to only create events for those features that have
dependency.
We got an event for a scheduled application success today that looked a
little something like this:
> Successfully applied the scheduled change request #1168 in the
production environment in project eg by gaston in project eg.
Notice that we're stating the project twice (once with a link (removed
here) and once without).
This PR removes the redundancy in CR events:
The project is already included in the `changeRequest` variable, which
is populated in `src/lib/addons/feature-event-formatter-md.ts` by
the `generateChangeRequestLink` function.
The (current) definition is:
```typescript
generateChangeRequestLink(event: IEvent): string | undefined {
const { preData, data, project, environment } = event;
const changeRequestId =
data?.changeRequestId || preData?.changeRequestId;
if (project && changeRequestId) {
const url = `${this.unleashUrl}/projects/${project}/change-requests/${changeRequestId}`;
const text = `#${changeRequestId}`;
const featureLink = this.generateFeatureLink(event);
const featureText = featureLink
? ` for feature flag ${this.bold(featureLink)}`
: '';
const environmentText = environment
? ` in the ${this.bold(environment)} environment`
: '';
const projectLink = this.generateProjectLink(event);
const projectText = project
? ` in project ${this.bold(projectLink)}`
: '';
if (this.linkStyle === LinkStyle.SLACK) {
return `${this.bold(`<${url}|${text}>`)}${featureText}${environmentText}${projectText}`;
} else {
return `${this.bold(`[${text}](${url})`)}${featureText}${environmentText}${projectText}`;
}
}
}
```
Which includes links, env, and project info already.
Weird thing is that I could not reproduce it locally, but I have a
theory to fix our delta mismatch.
Revisions are added to the delta every second.
This means that in a single revision, you can disable an event, remove a
dependency, and archive it simultaneously. These actions are usually
performed together since archiving an event will inherently disable it,
remove its dependencies, and so on.
Currently, we observe these events happening within the same revision.
However, since we were checking `.updated` last, the event was always
removed from the `removedMap`.
Now, by checking `.removed` last, the archive action will properly
propagate to the revision.
Our delta API was returning archived feature as updated. Now making sure
we do not put `archived-feature `event into `updated` event array.
Also stop returning removed as complex object.
## About the changes
Moved Open API validation handler to the controller layer to reuse on
all services such as project and segments, and also removed unnecessary
middleware at the top level, `app.ts`, and method, `useErrorHandler` in
`openapi-service.ts`.

Express cant' parse the path parameter because it doesn't be specified
on the `use` method. Therefore, it returns `undefined` as an error
message.
#### After

Express can parse the path parameter because I change to specify it on
the controller layer. Accordingly, it returns `test`.
Trying again, now with a tested function for resolvingIsOss.
Still want to test this on a pro instance in sandbox before we deploy
this to our customers to avoid what happened Friday.

When there is new revision, we will start storing memory footprint for
old client-api and the new delta-api.
We will be sending it as prometheus metrics.
The memory size will only be recalculated if revision changes, which
does not happen very often.
## About the changes
According to some logs, sdks can be undefined:
```
TypeError: Cannot read properties of null (reading 'sort')\n at /unleash/node_modules/unleash-server/dist/lib/db/client-applications-store.js:330:22\n
```
This is still raw and experimental.
We started to pull deleted features from event payload.
Now we put full query towards read model.

This PR refactors the method that listens on revision changes:
- Now supports all environments
- Removed unnecessary populate cache method
# Discussion point
In the listen method, should we implement logic to look into which
environments the events touched? By doing this we would:
- Reduce cache size
- Save some memory/CPU if the environment is not initialized in the
cache, because we could skip the DB calls.
This is based on the exising client feature toggle store, but some
alterations.
1. We support all of the querying it did before.
2. Added support to filter by **featureNames**
3. Simplified logic, so we do not have admin API logic
- no return of tags
- no return of last seen
- no return of favorites
- no playground logic
Next PR will try to include the revision ID.
This is not changing existing logic.
We are creating a new endpoint, which is guarded behind a flag.

Added more tests around specific plans. Also added snapshot as per our
conversation @gastonfournier, but I'm unsure how much value it will give
because it seems that the tests should already catch this using
respondWithValidation and the OpenAPI schema. The problem here is that
empty array is a valid state, so there were no reason for the schema to
break the tests.
From 13 seconds to 0.1 seconds.
1. Joining 1 million events to projects/features is slow. **Solved by
using CTE.**
2. Running grouping on 1 million rows is slow. **Solved by adding
index.**
