This change improves the responsiveness of the operator when handling
deletion requests by running sync operations in the background and
using context cancellation to interrupt stuck operations.
Changes:
- Add context field to Cluster struct, passed through New()
- Add Cancel() method to cancel cluster's context
- Add StartSync/EndSync/NeedsResync for managing background sync state
- Run Sync() in a background goroutine so worker can process other events
- Add context-aware DB connection methods (initDbConnWithContext)
- Add RetryWithContext() that respects context cancellation
- Cancel cluster context immediately when DeletionTimestamp detected
- Use context-aware connections in syncRoles/syncDatabases
- StartSync/NeedsResync check context cancellation to prevent new syncs
during deletion (no need for separate deleted flag)
Flow:
1. Sync event spawns background goroutine and returns immediately
2. If another sync arrives while one is running, needsResync flag is set
3. When sync completes, it checks needsResync and requeues if needed
4. Delete cancels context -> stuck DB operations return early -> mutex released
5. StartSync/NeedsResync return false when context cancelled
6. Delete proceeds without waiting for slow/stuck sync operations
When a Postgres cluster has a finalizer, deleting it sets a DeletionTimestamp
but doesn't remove the object until the finalizer is cleared. The operator
was not properly handling these DeletionTimestamp changes:
1. postgresqlUpdate() was filtering out events where only DeletionTimestamp
changed (it only checked Spec and Annotations), causing the delete to
never be processed.
2. EventUpdate case in processEvent() didn't check for DeletionTimestamp,
so even if the event reached the processor, it would run Update() instead
of Delete().
3. removeFinalizer() used a cached object with stale resourceVersion,
causing "object has been modified" errors.
Fixes:
- Add explicit DeletionTimestamp check in postgresqlUpdate() to queue the event
- Add DeletionTimestamp check in EventUpdate to call Delete() when set
- Fetch latest object from API before removing finalizer to avoid conflicts
