mod_serf: Add a FIXME, we are using ap_get_client_block() incorrectly.

spelling

Add lots of unique tags to error log messages

Remove more log message prefixes that are now redundant as the the error log format includes the module name.

Cleanup effort in prep for GA push: Trim trailing whitespace... no func change

Create wrapper API for apr_random; use in mod_lbmethod_heartbeat and mod_serf to - replace some needles use of apr_generate_random_bytes - remove code duplication

Various code cleanup PR: 51398 Submitted by: Christophe Jaillet <christophe jaillet wanadoo fr>

Fix various "variable 'x' set but not used" warnings.

Prevent segfault if URI is missing a scheme

Use the new APLOG_USE_MODULE/AP_DECLARE_MODULE macros everywhere to take advantage of per-module loglevels

When connecting to no http protocol response will be NULL and httpd cores.

Add port in the logic.

When using Heartmonitor choose the back-end randomly for the list provider by mod_heartmonitor.

handle an unfortunate implication of loadable MPMs: calls to ap_mpm_query() must be deferred until after the register-hooks hook, since that's where the MPM registers its mpm-query hook

ap_strchr_p() is the one that takes (protects) a const char *

clean up apr_time_from_msec() compatibility macros * where needed, base on APR_VERSION_AT_LEAST() so we remember what this is about * where not, axe

* modules/proxy/mod_serf.c (hb_server_sort): Use correct variables for sorting. Noticed by: Rüdiger

Add static cluster backend, for very simple configurations.

Add very basic, non-streaming, support for request bodies.

- Improve flushing/connection eos logic. - Use brigade_write instead of immortal buckets that aren't immortal. - Read HTTP status code from serf. - Remove extra logging.

Work in Progress. Convert the 100ms timed callback to a single cleanup callback that is added when the request is ready to finish. Basically works, though it has some issues with flushing and closing the connection.

If the MPM supports serf in its core, use this to drive the proxied request completely async from the original thread. Right now it uses a 100ms timer to determine when the request is actaully complete, but I think this can be removed in the long run with a better mechanism.

Add support for Preserving the client provided Host header. * modules/proxy/mod_serf.c (serf_config_t): Add preservehost member. (setup_request): If preservehost is set, use the client provided Host header, otherwise use the one from the configuration. (is_true): New helper function for decoding true/false strings. (add_pass): Change to an argv configuration function, check for not enough args, and parse everything after the URI into key/value pairs. (create_dir_config): Default to setting preservehost to on. (serf_cmds): Change add_pass to a take argv directive.

* modules/proxy/mod_serf.c (hb_list_servers): Allows relative paths for the heartbeat file.

Work in Progress. Add Clustered proxying support to mod_serf, by using the heartbeats system. No preconfiguration of cluster members is needed. Just a config like this: SerfCluster sweet heartbeat file=/var/cache/apache/hb.dat SerfCluster sour heartbeat file=/var/cache/apache/cluster2.dat <Location "/"> SerfPass cluster://sweet </Location> <Location "/different_cluster"> SerfPass cluster://sour </Location> The location of all possible destination servers is provided by a new providers interface, that includes configuration checking of the arguments to the SerfCluster command, solving one of the worst problems with the mod_proxy load balancer subsystem.

Umm, oops. r595022 shouldn't have ended up in trunk. Bad subversion - it crashed when commiting on a switched wc and committed to the wrong path! /me hits self on behalf of all SVN devs

Amsterdam sandbox: add serf input/output filters that replace the core filters.

Add mod_serf, a reverse proxy module, which uses serf[1] as its http client library. To enable, pass something like this to configure: --enable-serf --with-serf=/usr/local/serf/0.1.2 To try it out, put something like this in your httpd.conf: <Location /> SerfPass http://httpd.apache.org/ </Location> LocationMatch and all related directives can also be used, magical eh?
