*) mod_http2: Accept-Encoding is, when present on the initiating request,
added to push promises. This lets compressed content work in pushes.
by the client. [Stefan Eissing]
*) mod_http2: fixed possible read after free when streams were cancelled early
by the client. [Stefan Eissing]
*) mod_http2: fixed possible deadlock during connection shutdown. Thanks to
@FrankStolle for reporting and getting the necessary data.
[Stefan Eissing]
*) mod_http2: fixed apr_uint64_t formatting in a log statement to user proper
APR def, thanks to @Sp1l.
*) mod_http2: number of worker threads allowed to a connection is adjusting
dynamically. Starting with 4, the number is doubled when streams can be
served without block on http/2 connection flow. The number is halfed, when
the server has to wait on client flow control grants.
This can happen with a maximum frequency of 5 times per second.
When a connection occupies too many workers, repeatable requests
(GET/HEAD/OPTIONS) are cancelled and placed back in the queue. Should that
not suffice and a stream is busy longer than the server timeout, the
connection will be aborted with error code ENHANCE_YOUR_CALM.
This does *not* limit the number of streams a client may open, rather the
number of server threads a connection might use.
[Stefan Eissing]
*) mod_http2: allowing link header to specify multiple "rel" values,
space-separated inside a quoted string. Prohibiting push when Link
parameter "nopush" is present.
[Stefan Eissing]
*) mod_http2: reworked connection state handling. Idle connections accept a
GOAWAY from the client without further reply. Otherwise the
module makes a best effort to send one last GOAWAY to the client.
*) mod_http2: the values from standard directives Timeout and KeepAliveTimeout
properly are applied to http/2 connections.
[Stefan Eissing]
*) mod_http2: idle connections are returned to async mpms. new hook
"pre_close_connection" used to send GOAWAY frame when not already done.
Setting event mpm server config "by hand" for the main connection to
the correct negotiated server.
[Stefan Eissing]
*) mod_http2: keep-alive blocking reads are done with 1 second timeouts to
check for MPM stopping. Will announce early GOAWAY and finish processing
open streams, then close.
[Stefan Eissing]
*) mod_http2: bytes read/written on slave connections are reported via the
optional mod_logio functions. Fixes PR 58871.
*) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
to OCSP responders through a HTTP proxy. [Ruediger Pluem]
*) mod_cache_socache: Fix a possible cached entity body corruption when it
is received from an origin server in multiple batches and forwarded by
mod_proxy. [Yann Ylavic]
*) core: Add expression support to SetHandler.
[Eric Covener]
*) mod_remoteip: Prevent an external proxy from presenting an internal
proxy. PR 55962. [Mike Rumph]
*) core: Prevent a server crash in case of an invalid CONNECT request with
a custom error page for status code 400 that uses server side includes.
PR 58929 [Ruediger Pluem]
*) mod_ssl: handle TIMEOUT on empty SSL input as non-fatal, returning
APR_TIMEUP and preserving connection state for later retry.
[Stefan Eissing]
*) mod_ssl: Save some TLS record (application data) fragmentations by
including the last and subsequent suitable buckets when coalescing.
*) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,
"Error dispatching request", when the cause appears to be
due to the client closing the connection.
PR58118. [Tobias Adolph <adolph lrz.de>]
*) mod_cgid: Message AH02550, failure to flush a response to the client,
is now logged at TRACE1 level to match the underlying core output filter
severity. [Eric Covener]
*) mod_rewrite: Avoid looping on relative substitutions that
result in the same filename we started with. PR 58854.
[Eric Covener]
*) mime.types: add common extension "m4a" for MPEG 4 Audio.
PR 57895 [Dylan Millikin <dylan.millikin gmail.com>]
*) Added many log numbers to log statements that had none.

be inherited by virtual hosts that define a CustomLog.

pushed resources are kept. See directive H2PushDiarySize for managing this.
Push diaries can be initialized by clients via the "Cache-Digest" request
header. This carries a base64url encoded. compressed Golomb set as described
in https://datatracker.ietf.org/doc/draft-kazuho-h2-cache-digest/
Introduced a status handler for HTTP/2 connections, giving various counters
and statistics about the current connection, plus its cache digest value
in a JSON record. Not a replacement for more HTTP/2 in the server status.
Configured as
<Location "/http2-status">
SetHandler http2-status
</Location>
[Stefan Eissing]
*) mod_http2: Fixed flushing of last GOAWAY frame. Previously, that frame
did not always reach the client, causing some to fail the next request.
Fixed calculation of last stream id accepted as described in rfc7540.
Reading in KEEPALIVE state now correctly shown in scoreboard.
Fixed possible race in connection shutdown after review by Ylavic.
Fixed segfault on connection shutdown, callback ran into a semi dismantled session.
[Stefan Eissing]
*) mod_http2: Added support for experimental accept-push-policy draft
(https://tools.ietf.org/html/draft-ruellan-http-accept-push-policy-00). Clients
may now influence server pushes by sending accept-push-policy headers.
[Stefan Eissing]
*) mod_http2: new r->subprocess_env variables HTTP2 and H2PUSH, set to "on"
when available for request.
[Stefan Eissing]
*) mod_http2: fixed bug in input window size calculation by moving chunked
request body encoding into later stage of processing. Fixes PR 58825.
[Stefan Eissing]
*) core: new hook "pre_close_connection" which is run before the lingering
close of connections is started. This gives protocol handlers one last
chance to use a connection before it goes down.
[Stefan Eissing]
*) mod_status/scoreboard: showing connection protocol in new column, new
ap_update_child_status methods for updating server/description. mod_ssl
sets vhost negotiated by servername directly.
[Stefan Eissing]
*) mod_ssl: for all ssl_engine_vars.c lookups, fall back to master connection
if conn_rec itself holds no valid SSLConnRec*. Fixes PR58666.
[Stefan Eissing]
*) mod_http2: connection level window for flow control is set to protocol
maximum of 2GB-1, preventing window exhaustion when sending data on many
streams with higher cumulative window size.
Reducing write frequency unless push promises need to be flushed.
[Stefan Eissing]
*) mod_http2: required minimum version of libnghttp2 is 1.2.1
[Stefan Eissing]
*) mod_proxy_fdpass: Fix AH01153 error when using the default configuration.
In earlier version of httpd, you can explicitelly set the 'flusher' parameter
to 'flush' as a workaround. (i.e. flusher=flush)
Add documentation for the 'flusher' parameter when defining a proxy worker.
[Christophe Jaillet]
*) mod_ssl: For the "SSLStaplingReturnResponderErrors off" case, make sure
to only staple responses with certificate status "good". [Kaspar Brand]
*) mod_http2: new directive 'H2PushPriority' to allow priority specifications
on server pushed streams according to their content-type.
[Stefan Eissing]
*) mod_http2: fixes crash on connection abort for a busy connection.
fixes crash on a request that did not produce any response.
[Stefan Eissing]
*) mod_http2: trailers are sent after reponse body if set in request_rec
trailers_out before the end-of-request bucket is sent through the
output filters. [Stefan Eissing]
*) mod_http2: incoming trailers (headers after request body) are properly
forwarded to the processing engine. [Stefan Eissing]
*) mod_http2: new directive 'H2Push' to en-/disable HTTP/2 server
pushes a server/virtual host. Pushes are initiated by the presence
of 'Link:' headers with relation 'preload' on a response. [Stefan Eissing]
*) mod_http2: write performance of http2 improved for larger resources,
especially static files. [Stefan Eissing]
