Re-introduce check for sufficient PCRE version.

Add compiled and loaded PCRE version numbers to "httpd -V" output and to mod_info page.

Check for correct minimum PCRE version in configure, do not check in source code.

Clarify comment.

And use #error if we get past configure...

* Only use PCRE_DUPNAMES if it is present (only in more recent versions of PCRE)

Add a "MATCH_" prefix to variables set within LocationMatch/DirectoryMatch/FilesMatch.

core: Support named groups and backreferences within the LocationMatch, DirectoryMatch, FilesMatch and ProxyMatch directives.

Make ap_regcomp() return AP_REG_ESPACE if out of memory. Make ap_pregcomp() abort if out of memory. This raises the minimum PCRE requirement to version 6.0, released in 2005.

BZ 52623: Fix building against PCRE 8.30. PCRE dropped support for pcre_info() which is deprecated since a long time. Use pcre_fullinfo() instead, which exists since version 3.0 of PCRE. Patch provided by Ruediger Pluem.

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

Change the indentation to resemble the rest of the project. No code change.

Add ap_regexec_len() function that works with non-null-terminated strings. PR: 51231 Submitted by: Yehezkel Horowitz <horowity checkpoint com>, Stefan Fritsch

* server/util_pcre.c (ap_regerror): Use passed-in buffer size rather than the size of a pointer.

Introduce ap_rxplus class: higher-level regexps supporting perl-style regexp operations.

Code cleanup: replace strncpy by apr_cpystrn or apr_pstrmemdup Submitted by: Takashi Sato <takashi lans tv com> PR: 43432

revert last change

Update the last year of copyright.

No functional Change: Removing trailing whitespace. This also means that "blank" lines consisting of just spaces or tabs are now really blank lines

* server/util_pcre.c (ap_regexec): Fix --with-pcre build with older versions of pcre.

Get httpd-2.1 building once again on win32. NEVER NEVER screw around with redeclaring AP_ macros and constants. If the compiler won't pick them up, e.g., AP_DECLARE, ya've done something wrong from the start. All httpd/ap headers depend on httpd.h - plain and simple, so this un-convolutes the unusual order here. STATIC has become PCRE_STATIC, along with some other odd definitions. The only remaining emit is that _pcre_free export is imported, which implies something is unusual with the declaration. Still researching.

* include/ap_regex.h: Include apr.h not stdlib.h; replace pointless regoff_t typedef with int; s/size_t/apr_size_t/;. Comment fixes. * server/util_pcre.c: s/size_t/apr_size_t/. * include/httpd.h: Include stdlib.h here instead since many other files assume it was included by httpd.h at some point.

Move the POSIX reg* implementations into the ap_* namespace; internalise the ap_reg*<->PCRE wrapper: * configure.in: Add srclib/pcre to the include path. * include/ap_regex.h: Renamed from include/pcreposix.h. Prefix all constants with AP_; prefix all functions and types with ap_. Define AP_DECLARE to nothing if necessary. Remove regcomp error codes. * include/httpd.h: Include ap_regex.h not pcreposix.h. (ap_pregcomp, ap_regexec, ap_regfree): s/regex_t/ap_regex_t/. (ap_regexec, ap_regerror): Prototypes moved to ap_regex.h. * server/util.c (regex_cleanup, ap_pregcomp, ap_pregsub, ap_pregfree): Adjust for ap_ prefixed types. (ap_regexec, ap_regerror): Removed. * server/Makefile.in: Build util_pcre.c. * server/util_pcre.c: Copied from srclib/pcre/pcreposix.c; remove use of PCRE-internals to do error mapping; rename types to add AP_/ap_ prefixes as above. Use APR includes. (ap_regerror): Use apr_snprintf. * srclib/pcre/Makefile.in: Don't build pcreposix.c into libpcre.la. * modules/*: Update to use new type and constant names.
