Timothy Messier	9aa2d4cd84	test(session): Speed up some tests around dead worker cleanup ... 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.	4 years ago
Timothy Messier	79670180a7	refact(session): Move domain logic of Worker Status into domain service ... This creates a domain service function `session.WorkerStatusReport`. The service performs two functions: 1. Checks the status for all of the reported sessions, returning a report of the sessions that are in a "non-active" state, i.e. "cacneling" or "terminated". 2. Looks for any "orphaned" session connections, i.e. connections that are active but were not reported by the worker. These connections are marked as closed. This also removes the "ShouldCloseConnectionsOnWorker" logic, as this was determined to not be a possible state, and was unnecessary.	4 years ago
Timothy Messier	4de6464978	refact(session): Make CloseDeadConnectionsForWorker more testable ... 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.	4 years ago

Timothy Messier	99d0d2f682	wh: Add wh_credential_dimension and bridge tables ... This adds new dimension table to record credential information. Since a session can have multiple credentials, the wh_session_accumulating_fact is is linked to the credential_dimensions via bridge tables, wh_credential_group and wh_credential_group_membership. When a session is inserted, the credental group and credential dimensions will be upserted. If the group changed in any way, a new group is inserted along with all of the corresponding credentials.	5 years ago

Chris Marchesi	5a70875726	internal/servers/controller: Worker failure connection cleanup (#1340) ... This commit adds the support to do the following: * Mark connections for non-reporting workers as closed. This is the controller counterpart to the worker functionality (see #1330). This is written as a scheduled job that does the work DB-side in a single atomic query. * Works to reconcile states if such a broken controller-worker connection resumes and a worker reports a connection as connected that should be disconnected. In this case, the controller will send an update request, and the worker will honor it and terminate the connection. * Further refinement of the grace period setting has been added here. We have converged on the current server "liveness" setting as our default here, which is half of the previous 30s (15 seconds, in other words). Additionally, this is now configurable on the controller and worker side, with the caveat that it's currently impossible to do so in config as the setting has been untagged in HCL. This is exposed so that we can run some sophisticated testing scenarios where we skew the grace period to either the controller or worker to ensure the aforementioned reconciliation works. * Some repository functions have been added to support the new functionality, in addition to some test code to the worker to allow querying of session state while testing. * Finally, we've added some add timestamp subtraction functions as well, basically serving as the opposite of the addition functions.	5 years ago
