Spin off module-specific build options into separate build vars. [second try, supersedes r1385214] Add MOD_CFLAGS, MOD_LDFLAGS variables etc. to the build commands, which are available to modules for customization on a per-subdir basis (by adding definitions to modules.mk). Reduces the risk of side-effects when a module needs to add CFLAGS, LDFLAGS etc. and these would be added to the global settings (ALL_CFLAGS etc.). Adapt build settings for mod_ssl, mod_socache_dc, mod_deflate, mod_xml2enc, mod_proxy_html, and mod_lua to use the new MOD_xxx build variables. Change PICFLAGS, SHLTCFLAGS and LTCFLAGS into config vars, instead of AC_SUBSTing them in build/rules.mk.in. For support/ab, introduce ab_CFLAGS and ab_LDFLAGS, and define explicit make targets where they appear at the proper position in the build commands. Consistently use "--with-xxx=PATH" in configure help strings which are used to specify a path to the installation directory of an auxiliary package.

revert r1385214, as I inadvertently left out acinclude.m4.

* modules/filters/config.m4: Prevent libsed internals from polluting the global symbol namespace.

Change module sets and default activation status: 1) Promoted from "most" to "few" - mod_headers 2) Demoted from "yes" to "most" - mod_actions - mod_allowmethods - mod_auth_form - mod_buffer - mod_cgi(d) - mod_include - mod_negotiation - mod_ratelimit - mod_request - mod_userdir Remember: default module set is "most", but only the LoadModule lines of all modules except "yes" are commented out by default. The following modules will now be loaded by default: - mod_access_compat - mod_alias - mod_auth_basic - mod_authn_core - mod_authn_file - mod_authz_core - mod_authz_groupfile - mod_authz_host - mod_authz_user - mod_autoindex - mod_dir - mod_env - mod_filter - mod_headers - mod_log_config - mod_mime - mod_mpm_event - mod_reqtimeout - mod_setenvif - mod_status - mod_unixd - mod_version

Solaris doesn't support "test -e" in combination with "sh". We use "-f" in all other places.

Link the modules that use it against the XML library so the server will start.

Improve detection of libxml2

mod_xml2enc/mod_proxy_html drop Part 3: Introduce them to autoconf I expect this'll want further attention, but not tonight

Allow to specify module specific custom linker flags via the MOD_XXX_LDADD variables. Use APR_ADDTO instead of APR_SETVAR or direct variable assignment. This is especially useful when building mod_lua or mod_deflate against a lua resp. libz which are installed in non-standard locations. One can add "-R ..." to MOD_LUA_LDADD and MOD_DEFLATE_LDADD before configure to fix the RPATH/RUNPATH of those modules.

Tolerate dependency checking failures in configure for modules that have been enabled only implicitely.

Reset LDFLAGS after zlib testing for mod_deflate. Library flags are kept in MOD_DEFLATE_LDADD, not globally in LDFLAGS.

Respect platform specific runpath linker flag when building mod_deflate and mod_lua.

mod_data: Introduce a filter to support RFC2397 data URLs.

Add to modules' help text (displayed by ./configure -h) more information that will be useful in deciding whether to enable them or not.

Introduce mod_reflector, a handler capable of reflecting POSTed request bodies back within the response through the output filter stack. Can be used to turn an output filter into a web service.

Add mod_reqtimeout: New module to set timeouts and minimum data rates for receiving requests from the client.

Always make mod_*.h files available where they exist, modpath by modpath

Add a new module, mod_ratelimit, which can rate limit the outgoing bandwidth to a client. This module was originally written at Joost by Sander Striker, Justin Erenkrantz, and myself. We have been given permission by our employer to contribute this module.

mod_buffer: Optional support for buffering of the input and output filter stacks. Can collapse many small buckets into fewer larger buckets, and prevents excessively small chunks being sent over the wire.

Commit mod_sed: enable filtering of HTTP Requests and Responses through sed

Move the KeptBodySize directive, kept_body filters and the ap_parse_request_body function out of the http module and into a new module called mod_request, reducing the size of the core.

move mod_substitute from exp to filters

Move mod_filter and mod_charset_lite from /experimental/ to /filters/

* modules/filters/config.m4: Drop check for zutil.h. Add -lz to MOD_DEFLATE_LDADD to correctly support shared mod_deflate against static zlib (where possible).

Use -export-dynamic only when linking an httpd which includes mod_so, not when linking modules or support programs. * modules/aaa/config.m4, modules/arch/win32/config.m4, modules/cache/config.m4, modules/echo/config.m4, modules/filters/config.m4, modules/generators/config5.m4, modules/metadata/config.m4: Don't add -export-dynamic to LT_LDFLAGS. * modules/mappers/config9.m4: Add -export-dynamic to HTTPD_LDFLAGS when mod_so is enabled.

* modules/filters/config.m4: Fix typo which wiped INCLUDES if zlib detection failed.

Switch mod_deflate to 'most' status now. It's stable enough and will disable itself if zlib isn't found. PR: 15786

Use $INCLUDES rather than adding yet another place to edit include dirs.

Move mod_ext_filter out of experimental and into filters. See Attic in experimental directory for previous change history.

Remove warnings seen with Sun's Forte compiler.

Move mod_deflate from experimental to filters to represent our belief in its stability.

Fix httpd's definition of LTFLAGS to be consistent with that of apr and apr-util, allow it to be overridden by the configure command-line (default="--silent") and introduce LT_LDFLAGS to replace what we were formally abusing as LTFLAGS.

Completely revamp configure so that it preserves the standard make variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving the configure additions to EXTRA_* variables. Also, allow the user to specify NOTEST_* values for all of the above, which eliminates the need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to avoid pointless duplications. Fix the order in which flags are given on the compile and link lines.

Rename the module structures so that the exported symbol matches the file name, and it is easier to automate the installation process (generating LoadModule directives from the module filenames). Next step is to remove the 4th argument to the APACHE_MODULE macro completely and require people to use the matching names, and to reduce the LoadModule directive to 1 argument.... Objections?

*) remove STANDARD_LIBS line; it is unused/unneeded *) simplify by removing the extra AC_DEFUN() in each file

Get the modules configuration stuff working correctly. This just deals with STANDARD modules and Protocol, not MPMs.

Start to add back the config.m4 and Makefile.in's that were separated out during the repository move.
