# ChangeLog for http2 ## 5.3.9 * Using `ThreadManager` of `time-manager`. ## 5.3.8 * `forkManagedTimeout` ensures that only one asynchronous exception is thrown. Fixing the thread leak via `Weak ThreadId` and `modifyTVar'`. [#156](kazu-yamamoto/http2#156) ## 5.3.7 * Using `withHandle` of time-manager. * Getting `Handle` for each thread. * Providing allocSimpleConfig' to enable customizing WAI tiemout manager. * Monitor option (-m) for h2c-client and h2c-server. ## 5.3.6 * Making `runIO` friendly with the new synchronism mechanism. [#152](kazu-yamamoto/http2#152) * Re-throwing asynchronous exceptions to prevent thread leak. * Simplifying the synchronism mechanism between workers and the sender. [#148](kazu-yamamoto/http2#148) ## 5.3.5 * Using `http-semantics` v0.3. * Deprecating `numberOfWorkers`. * Removing `unliftio`. * Avoid `undefined` in client. [#146](kazu-yamamoto/http2#146) ## 5.3.4 * Support stream cancellation [#142](kazu-yamamoto/http2#142) ## 5.3.3 * Enclosing IPv6 literal authority with square brackets. [#143](kazu-yamamoto/http2#143) ## 5.3.2 * Avoid unnecessary empty data frames at end of stream [#140](kazu-yamamoto/http2#140) * Removing unnecessary API from ServerIO ## 5.3.1 * Fix treatment of async exceptions [#138](kazu-yamamoto/http2#138) * Avoid race condition [#137](kazu-yamamoto/http2#137) ## 5.3.0 * New server architecture: spawning worker on demand instead of the worker pool. This reduce huge numbers of threads for streaming into only 2. No API changes but workers do not terminate quicly. Rather workers collaborate with the sender after queuing a response and finish after all response data are sent. * All threads are labeled with `labelThread`. You can see them by `listThreas` if necessary. ## 5.2.6 * Recover rxflow on closing. [#126](kazu-yamamoto/http2#126) * Fixing ClientSpec for stream errors. * Allowing negative window. (h2spec http2/6.9.2) * Update for latest http-semantics [#122](kazu-yamamoto/http2#124) ## 5.2.5 * Setting peer initial window size properly. [#123](kazu-yamamoto/http2#123) ## 5.2.4 * Update for latest http-semantics [#122](kazu-yamamoto/http2#122) * Measuring performance concurrently for h2c-client ## 5.2.3 * Update for latest http-semantics [#120](kazu-yamamoto/http2#120) * Enable containers 0.7 (ghc 9.10) [#117](kazu-yamamoto/http2#117) ## 5.2.2 * Mark final chunk as final [#116](kazu-yamamoto/http2#116)

Instead of
raceing the background threads and the client, we run them concurrently and check which finishes first. If the background threads finished first, wewaitfor the client. If the client finished first, wecancelthe background threads and return.@kazu-yamamoto we also added a case in
sendGoAwayinNetwork.HTTP2.H2.Receiverso thatGoAwayIsSentis handled the same asConnectionIsClosed, which appears to more closely match the behavior of the frame sender. Also, previously ifGoAwayIsSenthappened, it would be wrapped in aBadThingHappenwhich would cause the frame sender to rethrow it. Does this change seem acceptable to you?Also, this does not communicate the stream id from a
GOAWAYto the client if the background threads finish first, but feel free to extend this PR to add that!
