Release 5.3.6

This maintenance release fixes a regression introduced by the previous release that can cause a temporary I/O spin during HTTP/2 connection shutdown in case the opposite endpoint fails to send a GOAWAY frame, and also fixes several bugs related to abnormal termination of HTTP/2 connections found since the last release.

Change Log

• Bug fix: #disconnected method of protocol handlers is to be called only once the underlying I/O session has been fully closed out. Contributed by Oleg Kalnichevski

• Bug fix: Fixed a race between async I/O session termination and command submission. Contributed by Oleg Kalnichevski

• Bug fix: Async I/O sessions to explicitly close the I/O channel for output in GRACEFUL close mode. Contributed by Oleg Kalnichevski

• Bug fix: Classic HTTP server to keep RequestListener thread running when an exception occurs during initialization of the incoming connection. Contributed by Christian de Waal

• Regression: Improved HTTP/2 connection termination in case of the opposite endpoint failing to send a GOAWAY frame (correction). Contributed by Oleg Kalnichevski

Release 5.3.5

This maintenance release fixes several corner cases in the H2 protocol handler that could have been potentially exploited to make H2 endpoints allocate extra resources and lead to Denial-of-Service conditions. This release also improves handling of H2 stream abnormal termination.

Change Log

• Improved H2 connection termination in case of the opposite endpoint failing to send GOAWAY frame. Contributed by Oleg Kalnichevski

• Bug fix: Corrected abnormal termination of H2 streams Contributed by Oleg Kalnichevski

@robertlazarski if you have the time, can you maybe take a quick look at the HeadersHandlerTests.testHeadersHandler? It has been flaky for a while (I created an issue at some point) but it never bothered me enough to spend too much time with it. But now that we test 3 Java versions in CI the issue of course surfaces even more often (for example in this run, the problems occur on all Java versions). I had a look at the test but I don't understand enough about the test context to really debug it (and I was not able to reproduce the issue locally yet). If you have any idea what the underlying issue might be, how we could better isolate this test or make it more resilient, I would appreciate any help.

[robertlazarski]

I gave this issue a shot and made a commit. If you see this error again, let me know.

[cortlepp]

Nice, thanks! I'll see how it goes.
