- version update to 2.4.52:
*) http: Enforce that fully qualified uri-paths not to be forward-proxied
have an http(s) scheme, and that the ones to be forward proxied have a
hostname, per HTTP specifications. [Ruediger Pluem, Yann Ylavic]
*) OpenSSL autoconf detection improvement: pick up openssl.pc in the
specified openssl path. [Joe Orton]
*) mod_proxy_connect, mod_proxy: Do not change the status code after we
already sent it to the client.
*) mod_http: Correctly sent a 100 Continue status code when sending an interim
response as result of an Expect: 100-Continue in the request and not the
current status code of the request. PR 65725 [Ruediger Pluem]
*) mod_dav: Some DAV extensions, like CalDAV, specify both document
elements and property elements that need to be taken into account
when generating a property. The document element and property element
are made available in the dav_liveprop_elem structure by calling
dav_get_liveprop_element(). [Graham Leggett]
*) mod_dav: Add utility functions dav_validate_root_ns(),
dav_find_child_ns(), dav_find_next_ns(), dav_find_attr_ns() and
dav_find_attr() so that other modules get to play too.
[Graham Leggett]
*) mpm_event: Restart stopping of idle children after a load peak. PR 65626.
[Yann Ylavic, Ruediger Pluem]
*) mod_http2: fixes 2 regressions in server limit handling.
1. 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.
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.
