It was determined that it is a more common use case for users to request
non-terminated sessions (i.e. sessions in `pending`, `active`, or
`canceling` when requesting sessions. Notably, end users would need
non-terminated sessions to:
- Establish a new connection to a session.
- Terminate a session
So now by default a list request to `/v1/sessions` will *not* include
terminated sessions.
To still enable use cases where terminated sessions are needed, this
adds a new query parameter to include the terminated session:
`/v1/sessions?include_terminated=true`.
Note that this query parameter is considered experimental and subject to
change.
* Remove the server_id from session table, change it to worker_id on session_connection
This is step 1 in updating the worker table. The worker is becoming a public resource so it must have
a public id. We drop the server_id column on the session_connection table and add the worker_id column
so we can use the wt_public_key type. Since db migrations are applied while the controller is offline,
it should be safe to assume all session connections are not in a running state, thus allowing us to null
out all the worker ids in the session_connection table.
For now we don't have very good enforcement of the wt_public_id constraints, since the id is currently
defined in the worker config, but this will soon change and the worker's id will be generated by the
controller.
* Move the session cleanup job logic into the session package.
This is part of a broader effort to more narrowly define the purpose of the internal/server directory to be for interacting with servers themselves. Future changes will continue to remove things from this directory until the purpose of the directory is clearly working primarily with the boundary servers resource.
This removes or reduces the time that is waited in a number of tests by
allowing the grace period time be a configuration option on the
connection repository.
The query for CloseDeadConnectionsForWorker includes a time comparison
to exclude results that are too close to the current time. This is done
to account for a delay in reporting by the worker. However, since the
delay was hardcoded in the query, it made it difficult to test.
This moves the delay duration into a parameter that is set on the
repository. The amount of the delay can be set at repository creation
time using the new WithWorkerStateDelay option. This defaults to the
previously hardcoded amount.
This will allow tests to control the delay to exercise this
functionality fully.
