Remove some assumptions that prevent subscription listeners from working on an
instance. This means allowing the host to forward the event from the instance
to the controller; correctly storing subscription listeners by address rather
than by connection; and a bunch of network and event stuff to correctly clean up
a listener.
Remove the assumption that all subscriptions events contains the updates
property. This meant fixing inconsistent types; always checking if the property
existed; fixing lots of the tests that made incorrect assumptions.
Minior fixes:
- Fix double firing of listener callbacks on first connection.
- Fix synced being set to true too early on first connection.
- Fix edge case interaction between last response and last snapshot for values
with updated set as 0.
Also change the the output made during the start of tests to indicate something
is happening when start up is slow and allow for silent testing to reduce the
amount of text output to the console.
If the value in a subscribed list is updated while the updatedAtMs
timestamp is kept the same then the caching logic of the subscription
system will cause updates to be silently dropped. Log a warning if a
subscriber catches this happening to help tracking down such cases.
Add suffixes like Ms and Ns to variables whos time unit is not in
seconds. This is aligning with a new code style of putting units
on variables that are not in SI base units.
Process updates of the resource EventSubscriber are subscribed to and
have it keep a mapping of id to value syncronised with event provider as
long as there are subscription callbacks registered with it. The
mapping is kept around after the last callback is unsubscribed so that
it can be efficiently resynced with the resource based on the updatedAt
timestaps of individual elements.
This allows the EventSubscriber to provide the right building blocks to
provide its values to React components via the the useSyncExternalStore
hook. This in turn greatly simplifies the web_ui models for the
subscribed resources.
Reduce complexity in the implementation of EventSubscriber by requiring
a control link be passed to its constructor. This is possible after the
change in 8c724e3 made the web interface control instance available to
plugins at init time.
Since subscriptions are handlede per link there's no need for the
eventReplay to be returned as a part of the SubscriptionRequest, it can
be sent and processed normally as an event. Simplify the logic by
sending eventReplay as an event and remove SubscriptionResponse.
Remove the reliance a reference to the Controller to get the link that a
subscription is tied to by explicitly handling the SubscriptionRequest
and passing the link to the SubscriptionController.
Notify the SubscriptionController that a connection closed from the
Connection instead of having the subscription controller set up an event
to do so. This simplifies the logic on the SubscriptionController's
side.
Entites that didn't have an updatedAt time at the time of creation will
default to having one set to 0. Since entities with an updatedAt time
greater than lastResponseTime is expected to be returned this means that
these entities would not be included when a client does its initial sync
subscribing to a resource. Change the default lastResponseTime
requested so that these entities are included.
Skip calling the subscription function that should provide an event
replay if the client is unsubscribing from the event. This avoids
having to check if the client is subscribing in every subscription
function.
Use the JSON data class pattern for User, Role, and PlayerStats and move
them into lib/src/data. This means that User is purely data now and
can't reference role objects directly. To make it possible easily check
permissions attached to roles and store data only visible on the
controller on user objects a ControllerUser type is introduced which is
linked with the UserManager and can therefore reference role objects
directly.
Resolves#525.
When defining a generic type where a type argument is never used
as a part of the type itself, TypeScript will consider two instances of
the generic type with different values for the type to be the same.
This caused the handle method to accept any handler for any
Request/Event, ignoring the event/request type completely.
Fix by specifying the constructor to return the intersection of the type
itself and the Request/Event type.
Remove extra whitespace, use more consistent spacing, add missing
semicolons, using dangling commas, break up long lines, consistent
multiline operator placement, add missing JSDoc strings and so on.
