All, This set of changes provided multiple improvements to the HTTP/2 implementation: 1. The memory used by closed streams is significantly reduced (hopefully without the NPEs triggered by my previous attempt). 2. We retain information on more streams in the priority tree. This enables greater latitude for clients that send frames for streams that have been closed (while not increasing memory). 3. We no longer aggressively prune the priority tree to just active streams (this was causing problems in some usage patterns). My plan is to let this run on the CI for a few days and then - assuming no issues - back-port it early next week.
