*) mod_http2: version 2.0.10 of the module, synchronizing changes
with the gitgub version. This is a partial rewrite of how connections and streams are handled. - an APR pollset and pipes (where supported) are used to monitor the main connection and react to IO for request/response handling. This replaces the stuttered timed waits of earlier versions. - H2SerializeHeaders directive still exists, but has no longer an effect. - Clients that seemingly misbehave still get less resources allocated, but ongoing requests are no longer disrupted. - Fixed an issue since 1.15.24 that "Server" headers in proxied requests were overwritten instead of preserved. [PR by @daum3ns] - A regression in v1.15.24 was fixed that could lead to httpd child processes not being terminated on a graceful reload or when reaching MaxConnectionsPerChild. When unprocessed h2 requests were queued at the time, these could stall. See #212. - Improved information displayed in 'server-status' for H2 connections when Extended Status is enabled. Now one can see the last request that IO operations happened on and transferred IO stats are updated as well. - When reaching server limits, such as MaxRequestsPerChild, the HTTP/2 connection send a GOAWAY frame much too early on new connections, leading to invalid protocol state and a client failing the request. See PR65731 at <https://bz.apache.org/bugzilla/show_bug.cgi?id=65731>. The module now initializes the HTTP/2 protocol correctly and allows the client to submit one request before the shutdown via a GOAWAY frame is being announced. - :scheme pseudo-header values, not matching the connection scheme, are forwarded via absolute uris to the http protocol processing to preserve semantics of the request. Checks on combinations of pseudo-headers values/absence have been added as described in RFC 7540. Fixes #230. - A bug that prevented trailers (e.g. HEADER frame at the end) to be generated in certain cases was fixed. See #233 where it prevented gRPC responses to be properly generated. - Request and response header values are automatically stripped of leading and trialing space/tab characters. This is equivalent behaviour to what Apache httpd's http/1.1 parser does. The checks for this in nghttp2 v1.50.0+ are disabled. - Extensive testing in production done by Alessandro Bianchi (@alexskynet) on the v2.0.x versions for stability. Many thanks! *) mod_proxy_http2: fixed #235 by no longer forwarding 'Host:' header when request ':authority' is known. Improved test case that did not catch that the previous 'fix' was incorrect. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/branches/2.4.x@1906475 13f79535-47bb-0310-9956-ffa450edef68
