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.

In some of the places we used `NoAccessError` for permissions, other
places we used it for a more generic 403 error with a different
message. This refactoring splits the error type into two distinct
types instead to make the error messages more consistent.
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 adds openapi documentation for the Auth tagged operations and
connected schemas.
## Discussion points
Our user schema seems to be exposing quite a bit of internal fields, I
flagged the isApi field as deprecated, I can imagine quite a few of
these fields also being deprecated to prepare for removal in next major
version, but I was unsure which ones were safe to do so with.
## Observation
We have some technical debt around the shape of the schema we're
claiming we're returning and what we actually are returning. I believe
@gastonfournier also observed this when we turned on validation for our
endpoints.

This PR adds strategy titles as an optional bit of data added to client
features. It's only added when prompted.
## Discussion points:
### getPlaygroundFeatures
The optional `includeStrategyId` parameter has been replaced by a
`getPlaygroundFeatures` in the service (and in the underlying store).
The playground was the only place that used this specific include, so
instead of adding more and making the interface for that method more
complex, I created a new method that deals specifically with the
playground.
The underlying store still uses an `optionalIncludes` parameter,
however. I have a plan to make that interface more fluid, but I'd like
to propose that in a follow-up PR.

## About the changes
`getUserRootRoles` should also consider custom root roles
This introduces test cases that unveiled a dependency between stores
(this happens actually at the DB layer having access-service access
tables from two different stores but skipping the store layer).
https://linear.app/unleash/issue/2-1161/a-user-with-custom-root-role-and-permission-to-create-client-api
---------
Co-authored-by: Nuno Góis <github@nunogois.com>
## What
As part of the move to enable custom-root-roles, our permissions model
was found to not be granular enough to allow service accounts to only be
allowed to create read-only tokens (client, frontend), but not be
allowed to create admin tokens to avoid opening up a path for privilege
escalation.
## How
This PR adds 12 new roles, a CRUD set for each of the three token types
(admin, client, frontend). To access the `/api/admin/api-tokens`
endpoints you will still need the existing permission (CREATE_API_TOKEN,
DELETE_API_TOKEN, READ_API_TOKEN, UPDATE_API_TOKEN). Once this PR has
been merged the token type you're modifying will also be checked, so if
you're trying to create a CLIENT api-token, you will need
`CREATE_API_TOKEN` and `CREATE_CLIENT_API_TOKEN` permissions. If the
user performing the create call does not have these two permissions or
the `ADMIN` permission, the creation will be rejected with a `403 -
FORBIDDEN` status.
### Discussion points
The test suite tests all operations using a token with
operation_CLIENT_API_TOKEN permission and verifies that it fails trying
to do any of the operations against FRONTEND and ADMIN tokens. During
development the operation_FRONTEND_API_TOKEN and
operation_ADMIN_API_TOKEN permission has also been tested in the same
way. I wonder if it's worth it to re-add these tests in order to verify
that the permission checker works for all operations, or if this is
enough. Since we're running them using e2e tests, I've removed them for
now, to avoid hogging too much processing time.

Adds an environment variable for switching off feature telemetry in
version check
## About the changes
Implements custom root roles, encompassing a lot of different areas of
the project, and slightly refactoring the current roles logic. It
includes quite a clean up.
This feature itself is behind a flag: `customRootRoles`
This feature covers root roles in:
- Users;
- Service Accounts;
- Groups;
Apologies in advance. I may have gotten a bit carried away 🙈
### Roles
We now have a new admin tab called "Roles" where we can see all root
roles and manage custom ones. We are not allowed to edit or remove
*predefined* roles.
This meant slightly pushing away the existing roles to `project-roles`
instead. One idea we want to explore in the future is to unify both
types of roles in the UI instead of having 2 separate tabs. This
includes modernizing project roles to fit more into our current design
and decisions.
Hovering the permissions cell expands detailed information about the
role:
### Create and edit role
Here's how the role form looks like (create / edit):
Here I categorized permissions so it's easier to visualize and manage
from a UX perspective.
I'm using the same endpoint as before. I tried to unify the logic and
get rid of the `projectRole` specific hooks. What distinguishes custom
root roles from custom project roles is the extra `root-custom` type we
see on the payload. By default we assume `custom` (custom project role)
instead, which should help in terms of backwards compatibility.
### Delete role
When we delete a custom role we try to help the end user make an
informed decision by listing all the entities which currently use this
custom root role:
~~As mentioned in the screenshot, when deleting a custom role, we demote
all entities associated with it to the predefined `Viewer` role.~~
**EDIT**: Apparently we currently block this from the API
(access-service deleteRole) with a message:
What should the correct behavior be?
### Role selector
I added a new easy-to-use role selector component that is present in:
- Users
- Service Accounts
- Groups
### Role description
I also added a new role description component that you can see below the
dropdown in the selector component, but it's also used to better
describe each role in the respective tables:
I'm not listing all the permissions of predefined roles. Those simply
show the description in the tooltip:
### Role badge
Groups is a bit different, since it uses a list of cards, so I added yet
another component - Role badge:
I'm using this same component on the profile tab:
## Discussion points
- Are we being defensive enough with the use of the flag? Should we
cover more?
- Are we breaking backwards compatibility in any way?
- What should we do when removing a role? Block or demote?
- Maybe some existing permission-related issues will surface with this
change: Are we being specific enough with our permissions? A lot of
places are simply checking for `ADMIN`;
- We may want to get rid of the API roles coupling we have with the
users and SAs and instead use the new hooks (e.g. `useRoles`)
explicitly;
- We should update the docs;
- Maybe we could allow the user to add a custom role directly from the
role selector component;

## About the changes
When a feature is not found in a project we should fail with a NotFound
error. If the feature belongs to a different project, it should not be a
permission issue, because the user might not be aware (lack of
permissions/visibility) of that other project, so even in this case the
error should be NotFound (this also works if we ever allow the same
feature name in different projects)

Improves the behavior of disabling password based login by adding some
relevant information and a confirmation dialog with a warning. This felt
better than trying to disable the toggle, by still allowing the end
users to make the decision, except now it should be a properly informed
decision with confirmation.
- **Password based administrators**: Admin accounts that have a password
set;
- **Other administrators**: Other admin users that do not have a
password. May be SSO, but may also be users that did not set a password
yet;
- **Admin service accounts**: Service accounts that have the admin root
role. Depending on how you're using the SA this may not necessarily mean
locking yourself out of an admin account, especially if you secured its
token beforehand;
- **Admin API tokens**: Similar to the above. If you secured an admin
API token beforehand, you still have access to all features through the
API;
Each one of them link to the respective page inside Unleash (e.g. users
page, service accounts page, tokens page...);
If you try to disable and press "save", and only in that scenario, you
are presented with the following confirmation dialog:

This PR attempts to improve the error handling introduced in #3607.
## About the changes
## **tl;dr:**
- Make `UnleashError` constructor protected
- Make all custom errors inherit from `UnleashError`.
- Add tests to ensure that all special error cases include their
relevant data
- Remove `PasswordMismatchError` and `BadRequestError`. These don't
exist.
- Add a few new error types: `ContentTypeError`, `NotImplementedError`,
`UnauthorizedError`
- Remove the `...rest` parameter from error constructor
- Add an unexported `GenericUnleashError` class
- Move OpenAPI conversion function to `BadDataError` clas
- Remove explicit `Error.captureStackTrace`. This is done automatically.
- Extract `getPropFromString` function and add tests
### **In a more verbose fashion**
The main thing is that all our internal errors now inherit
from`UnleashError`. This allows us to simplify the `UnleashError`
constructor and error handling in general while still giving us the
extra benefits we added to that class. However, it _does_ also mean that
I've had to update **all** existing error classes.
The constructor for `UnleashError` is now protected and all places that
called that constructor directly have been updated. Because the base
error isn't available anymore, I've added three new errors to cover use
cases that we didn't already have covered: `NotImplementedError`,
`UnauthorizedError`, `ContentTypeError`. This is to stay consistent in
how we report errors to the user.
There is also an internal class, `GenericUnleashError` that inherits
from the base error. This class is only used in conversions for cases
where we don't know what the error is. It is not exported.
In making all the errors inherit, I've also removed the `...rest`
parameter from the `UnleashError` constructor. We don't need this
anymore.
Following on from the fixes with missing properties in #3638, I have
added tests for all errors that contain extra data.
Some of the error names that were originally used when creating the list
don't exist in the backend. `BadRequestError` and
`PasswordMismatchError` have been removed.
The `BadDataError` class now contains the conversion code for OpenAPI
validation errors. In doing so, I extracted and tested the
`getPropFromString` function.
### Main files
Due to the nature of the changes, there's a lot of files to look at. So
to make it easier to know where to turn your attention:
The changes in `api-error.ts` contain the main changes: protected
constructor, removal of OpenAPI conversion (moved into `BadDataError`.
`api-error.test.ts` contains tests to make sure that errors work as
expected.
Aside from `get-prop-from-string.ts` and the tests, everything else is
just the required updates to go through with the changes.
## Discussion points
I've gone for inheritance of the Error type over composition. This is in
large part because throwing actual Error instances instead of just
objects is preferable (because they collect stack traces, for instance).
However, it's quite possible that we could solve the same thing in a
more elegant fashion using composition.
## For later / suggestions for further improvements
The `api-error` files still contain a lot of code. I think it might be
beneficial to break each Error into a separate folder that includes the
error, its tests, and its schema (if required). It would help decouple
it a bit.
We don't currently expose the schema anywhere, so it's not available in
the openapi spec. We should look at exposing it too.
Finally, it would be good to go through each individual error message
and update each one to be as helpful as possible.
This PR removes the usage of crOnVariants flag, but keeps the behaviour,
so CR are now enabled on variants.

This PR implements the first version of a suggested unification (and
documentation) of the errors that we return from the API today.
The goal is for this to be the first step towards the error type defined
in this internal [linear
task](https://linear.app/unleash/issue/1-629/define-the-error-type
'Define the new API error type').
## The state of things today
As things stand, we currently have no (or **very** little) documentation
of the errors that are returned from the API. We mention error codes,
but never what the errors may contain.
Second, there is no specified format for errors, so what they return is
arbitrary, and based on ... Who knows? As a result, we have multiple
different errors returned by the API depending on what operation you're
trying to do. What's more, with OpenAPI validation in the mix, it's
absolutely possible for you to get two completely different error
objects for operations to the same endpoint.
Third, the errors we do return are usually pretty vague and don't really
provide any real help to the user. "You don't have the right
permissions". Great. Well what permissions do I need? And how would I
know? "BadDataError". Sick. Why is it bad?
... You get it.
## What we want to achieve
The ultimate goal is for error messages to serve both humans and
machines. When the user provides bad data, we should tell them what
parts of the data are bad and what they can do to fix it. When they
don't have the right permissions, we should tell them what permissions
they need.
Additionally, it would be nice if we could provide an ID for each error
instance, so that you (or an admin) can look through the logs and locate
he incident.
## What's included in **this** PR?
This PR does not aim to implement everything above. It's not intended to
magically fix everything. Its goal is to implement the necessary
**breaking** changes, so that they can be included in v5. Changing error
messages is a slightly grayer area than changing APIs directly, but
changing the format is definitely something I'd consider breaking.
So this PR:
- defines a minimal version of the error type defined in the [API error
definition linear
task](https://linear.app/unleash/issue/1-629/define-the-error-type).
- aims to catch all errors we return today and wrap them in the error
type
- updates tests to match the new expectations.
An important point: because we are cutting v5 very soon and because work
for this wasn't started until last week, the code here isn't necessarily
very polished. But it doesn't need to be. The internals can be as messy
as we want, as long as the API surface is stable.
That said, I'm very open to feedback about design and code completeness,
etc, but this has intentionally been done quickly.
Please also see my inline comments on the changes for more specific
details.
### Proposed follow-ups
As mentioned, this is the first step to implementing the error type. The
public API error type only exposes `id`, `name`, and `message`. This is
barely any more than most of the previous messages, but they are now all
using the same format. Any additional properties, such as `suggestion`,
`help`, `documentationLink` etc can be added as features without
breaking the current format. This is an intentional limitation of this
PR.
Regarding additional properties: there are some error responses that
must contain extra properties. Some of these are documented in the types
of the new error constructor, but not all. This includes `path` and
`type` properties on 401 errors, `details` on validation errors, and
more.
Also, because it was put together quickly, I don't yet know exactly how
we (as developers) would **prefer** to use these new error messages
within the code, so the internal API (the new type, name, etc), is just
a suggestion. This can evolve naturally over time if (based on feedback
and experience) without changing the public API.
## Returning multiple errors
Most of the time when we return errors today, we only return a single
error (even if many things are wrong). AJV, the OpenAPI integration we
use does have a setting that allows it to return all errors in a request
instead of a single one. I suggest we turn that on, but that we do it in
a separate PR (because it updates a number of other snapshots).
When returning errors that point to `details`, the objects in the
`details` now contain a new `description` property. This "deprecates"
the `message` property. Due to our general deprecation policy, this
should be kept around for another full major and can be removed in v6.
```json
{
"name": "BadDataError",
"message": "Something went wrong. Check the `details` property for more information."
"details": [{
"message": "The .params property must be an object. You provided an array.",
"description": "The .params property must be an object. You provided an array.",
}]
}
```
