## About the changes
App stats is mainly used to cap the number of applications reported to
Unleash based on the last 7 days information:
cc2ccb1134/src/lib/middleware/response-time-metrics.ts (L24-L28)
Instead of getting all stats, just calculate appCount statistics
Use scheduler service instead of setInterval
On all pods and instances, we run the same revision update query every
second. It is relatively fast when the application has started. This is
the single most ran query in unleash.
Benchmarks:
1. Running pod with existing revisionID:
- old 5.5ms
- new 0.028ms
2. New pod without existing revisionID
- old 9.329ms
- new 0.033ms
This query is getting optimized
7e66a79f9f/src/lib/features/events/event-store.ts (L161)
We have customers with tens or hundreds of thousands of applications,
and we have a scheduler running that sets application fields to
`announced` as true. However, every time it runs, it queries the entire
table, which is slow and causes database connection acquisition issues.
To make it faster, we added a partial index to the table.
This PR updates the change request email sending method to handle the
recent changes we have made. That means that the email now:
- says that change requests have been suspended instead of saying that
application will fail.
- handles cases where segments or strategies have been updated causing
potential conflicts.
I have updated the email templates and made some adjustments to the
email sending method. To make the transition from one to the other
easier, I have kept the original method as an interim solution until
enterprise has switched over.

To prevent starving our db connections, we can cache this data that
rarely changes and clear the cache when we see changes. Because we will
only clear changes in the node receiving the change we're only caching
the data for 1 minute.
This should give us some room to test if this solution will work

In the beginning we used process.nextTick() as a trick to load some data
initally in the constructor of a service.
This is a bad pattern and we should generally avoid any async operations
in the constructor. Today we have two alternatives:
1. Defer loading until data is needed (wrap it in async)
2. Use the schdule-service.
When a stop signal is sent to Unleash the scheduler-service should
cancel any scheduled jobs. This also applies to the job scheduled for
initial execution with jitter.
We observed that initial jobs was executed after the database
connections are terminated. This appears after v5.9.0 of Unleash.

## About the changes
Queries on client-feature-toggle store have many purposes depending on
the requestType, making the query more complex or not depending on the
use case. Also, each use case has different frequencies (i.e. playground
is expected to be used rarely).
The name for the store metrics was wrong, copy&pasted from:
7b04db0547/src/lib/features/feature-toggle/feature-toggle-store.ts (L107)
Which was also present in feature-tag metrics:
7b04db0547/src/lib/db/feature-tag-store.ts (L37)
With this, we'll have more granularity to understand the execution time
and frequency of each
Usually maintenance mode is disabled. If the call throws, which we see a
lot of when a unleash instance is in terminating state, we should return
a default value.
By having it throw inside of the memoizee function, the response is not
cached, and it will trigger new calls until it return a cachable result.
## About the changes
Every schedule job will now check if maintenance is enabled. This ends
up querying the settings table in the db at least once per second per
running unleash instance. This small fix caches this query for 60
seconds to reduce the load somewhat.
We should reconsider this solution for the long term, but this will be a
great improvement on the short term.
**Logs after this fix running locally.**
We can observe that we resolve settings from the DB once per minute.

Also we should consider giving a warning in section where you enable
maintenance mode that it can take up to a minute to propagate.
## About the changes
the created_by_user_id data migration from resolving events.created_by
(for both events and features) now emits events on how many rows were
updated.
Adds listeners for these events that records these metrics with
prometheus

We were sending `user.id` to the service, but if an admin token is used,
there is no `user.id.` Instead, there is
`user.internalAdminTokenUserId`. so we need to use the special method
`extractUserIdFromUser`.
This PR adds this implementation, and now the service correctly
retrieves the appropriate ID for admins.
Related to: https://github.com/Unleash/unleash/pull/5924
## About the changes
Schedules a best-effort task setting the value of
events.created_by_user_id based on what is found in the created_by
column and if it's capable of resolving that to a userid/a system id.
The process is executed in the events-store, it takes a chunk of events
that haven't been processed yet, attempts to join users and api_tokens
tables on created_by = username/email, loops through and tries to figure
out an id to set. Then updates the record.

## About the changes
Change the sorting of features to migrate created_by_user_id for, and
filter out unresolvable feature/users
Query tested manually in enterprise
## About the changes
Resets created_by_user_id on events incorrectly marked as -1337 when an actual user has been set in created_by column, to clean up after a bug
## About the changes
Sets data migration of features and events created_by_user_id to
disabled by default
Map to promise and await all in created by user id migration for features
This escape with `??` double escaped the LIKE query causing no results.
This updates to using whereLike, which does the correct escaping for
string query.
## About the changes
Adds a scheduled task that every 5 seconds updates 500 entries in the
features table setting `created_by_user_id`.
It does this by looking at the related event, checks created_by and
joins users table for match on username or email, and joins api_tokens
table on username matches. Then picks either a users id if set, or uses
-42 (admin token user)
## About the changes
This PR replaces the old systemUser -1 in user-service.ts with the new
SYSTEM_USER -1337 and adds a migration to move events created_by = -1 to
-1337
## Discussion points
Does it make sense to do both of these things? Or should we skip the
migration? How would this behave in a large system with hundreds of
thousands of events, should this be split up?
Only triggers if there is any rows in client instances that have
sdk_version: unleash-edge with version < 17.0.0
The function that checks this memoizes the check for 10 minutes to avoid
scanning the client instances table too often.
Previously we used a killswitch and returned 404 if the feature was
enabled. This flips that to a default disabled toggle, that has to be
turned on to handle old Edge (pre 17.0.0) posting bulk metrics
We should use the enhanced flagResolver

This PR will allow us to use a feature flag with variants to control
whether or not we should show the comments field of the feedback form.
This will allow us to see whether we can increase feedback collection if
we reduce the load on the customer.
## About the changes
This was spotted while testing automated actions. Steps to reproduce:
1. Add an editor user
2. Get a PAT for the editor user
3. As Admin create a feature in a project where the editor user is not a
member and enable the feature
4. Try using the editor's PAT to modify the feature
5. As the editor create a project (you'd be made owner) and try the same
request but just change the project name for the new project just
created (don't change anything else)
**Expected behavior**: you can't disable the feature
**Actual behavior**: the feature is disabled
This does not happen when trying to turn on a flag because during the
turn-on process we do validate if the feature belongs to project when we
call updateStrategy:
c18a7c0dc2/src/lib/features/feature-toggle/feature-toggle-service.ts (L1751-L1764)
https://linear.app/unleash/issue/2-1856/add-typesafe-wrappers-over-prom-clients-metrics
As discussed on the latest knowledge sharing session, this adds typesafe
wrappers over prom client's metrics, requiring us to specify all the
configured labels for each metric.
This uses a functional approach and only exposes the methods that are
currently relevant to us, while also exposing the underlying instance of
the metric for an easy access if needed.
Since we often chain `labels` with `inc` in counters, this adds a
convenience `increment` method for counters which does both in a single
call.
Uses a new `URL_SAFE_BASIC` regex constant that checks for characters
that are commonly used in URL path sections: alphanumeric lowercase
characters, dashes and underscores.
This will allow us to re-use this constant in our server-side
validation.
Follow up of https://github.com/Unleash/unleash/issues/4303
We are adding primary keys to all tables missing them, currently
**role_permission**, **api_token_project**, and **project_stats**.
By adding primary keys, the issue with migrations failing during
upgrades in replicated database setups will be resolved.
So, this was causing a lot of ERROR in our logs, due to the metric
having gotten an extra label the last month.
Two things for this fix.
1. add the missing label to the two calls that did not have it added
2. update the log line to include the error as another argument to the
logger, so we actually get a stacktrace from the error.
### What
Adds Read and Write permissions for project administration settings
(user access, change request settings, default strategy, other).
### Why
On request from two large customers that wanted our RBAC controls to be
more granulated to easier be able to limit the access they granted their
users.
## About the changes
Whenever we get a call from an admin token we want to associate it with
the [admin token
user](4d42093a07/src/lib/types/core.ts (L34-L41)).
This should give us the needed audit for this type of calls that
currently were lacking a user id (we only stored a string with the token
name in the event log).
We consciously decided not to use `id` as the property to prevent any
unforeseen side effects. The reason is that only `IUser` type has an id
and adding an id to `IApiUser` might lead to confusion.
Since we've now added PAT's we really do recommend switching to those,
or for enterprises, we recommend using service accounts.
Admin tokens have an obvious disadvantage in that they're not connected
to any user, so actions performed by them are harder to audit.
This PR adds a killswitch for turning it off, in preparation for
deprecating them and ultimately removing them in the future.
## About the changes
This admin token user will help us differentiate actions performed by
the system from actions performed with an admin token.
Events created with an admin token should have the id of this user as
createdByUserId property and the username of the token used as the
createdBy property. i.e.
```json
{
"id": 11,
"type": "pat-created",
"createdBy": "admin-token",
"createdAt": "2024-01-16T13:16:27.887Z",
"createdByUserId": -42,
"data": {
"description": "admin-pat",
"expiresAt": "2024-02-15T13:16:25.586Z",
"secret": "***",
"userId": 1
},
"preData": null,
"tags": [],
"featureName": null,
"project": null,
"environment": null
}
```
## About the changes
EventsService is a dependency in most of our services. This creates
helper methods to create them easily and replace a few places where
we're creating them manually
This change removes the system user's email from the definition, instead
setting it to `null`. It also changes the name to "Unleash System".
The IUser interface doesn't allow `null` email addresses, so we change
the type definition of the system user to get around it. However, using
`null` (instead of just removing the property entirely) is useful
because when you get the system user from the DB, it's email value will
be null (after it has been nulled out).
As of today, there is nowhere in the Unleash system (OSS or Enterprise)
where we use the system user as an IUser (we only use username and ID).
So this change shouldn't break anything.
This should follow https://github.com/Unleash/unleash/pull/5849.
Updates it from 'system@getunleash.io' to `null`. We don't have that
address registered (and probably don't want it), so we'll leave it
empty.
This is a companion PR to
https://github.com/Unleash/unleash/pull/5893. With both of those
merged, the system user in the DB should match the one defined in
`core.ts`
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`.
