* Merge PR 311:Stefan Eissing2022-04-131-5/+19
| | | | | | | | | | | | | | | | *) core/mod_http: use REQUEST meta buckets and a new HTTP/1.x specific input filter to separate the handling for HTTP requests from the handling of HTTP/1.x request parsing and checks. A new HTTP1_REQUEST_IN filter installs itself on http/1.1 connections before a request is being read. It generates either a REQUEST meta bucket on success or an ERROR bucket with the proposed response status. The core connection processing, relying on ap_read_request(), now expects a REQUEST or ERROR bucket from the input filters and is agnostic to specific HTTP versions and how they bring requests into the server. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1899799 13f79535-47bb-0310-9956-ffa450edef68

* *) core/mod_http/mod_http2:Stefan Eissing2022-04-041-0/+292
| | | | | | | | | | | | | | | | | | | - adds new meta bucket types REQUEST, RESPONSE and HEADERS to the API. - adds a new method for setting standard response headers Date and Server - adds helper methods for formatting parts of HTTP/1.x, like headers and end chunks for use in non-core parts of the server, e.g. mod_proxy - splits the HTTP_IN filter into a "generic HTTP" and "specific HTTP/1.x" filter. The latter one named HTTP1_BODY_IN. - Uses HTTP1_BODY_IN only for requests with HTTP version <= 1.1 - Removes the chunked input simulation from mod_http2 - adds body_indeterminate flag to request_rec that indicates that a request body may be present and needs to be read/discarded. This replaces logic that thinks without Content-Length and Transfer-Encoding, no request body can exist. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1899547 13f79535-47bb-0310-9956-ffa450edef68

* *) core: Adding SSL related inquiry functions to the server API.Stefan Eissing2021-02-231-0/+60
| | | | | | | | | | | | | | | | | | | | | | | These function are always available, even when no module providing SSL is loaded. They provide their own "shadowing" implementation for the optional functions of similar name that mod_ssl and impersonators of mod_ssl provide. This enables loading of several SSL providing modules when all but one of them registers itself into the new hooks. Two old-style SSL modules will not work, as they replace the others optional functions with their own. Modules using the old-style optional functions will continue to work as core supplies its own versions of those. The following has been added so far: - ap_ssl_conn_is_ssl() to query if a connection is using SSL. - ap_ssl_var_lookup() to query SSL related variables for a server/connection/request. - Hooks for 'ssl_conn_is_ssl' and 'ssl_var_lookup' where modules providing SSL can install their own value supplying functions. git-svn-id: https://svn.apache.org/repos/asf/httpd/httpd/trunk@1886840 13f79535-47bb-0310-9956-ffa450edef68
