(Not tested under Solaris yet) dnl dnl Revision 1.12 2001/07/25 19:16:27 oes dnl Bumping version number to 2.9.8 dnl dnl Revision 1.11 2001/07/21 18:00:07 jongfoster dnl Bumping version number to 2.9.7 dnl dnl Revision 1.10 2001/07/18 17:25:04 oes dnl Fixed a typo dnl dnl Revision 1.9 2001/07/15 19:45:13 jongfoster dnl Added support for linking with POSIX threads library dnl dnl Revision 1.8 2001/07/15 17:54:29 jongfoster dnl Renaming #define STATIC to STATIC_PCRE dnl Adding new #define FEATURE_PTHREAD that will be used to enable dnl POSIX threads support. dnl dnl Revision 1.7 2001/07/13 13:58:05 oes dnl Completely reorganized the selection scheme for dnl pcre, pcreposix, pcrs and gnu_regex: dnl dnl The presence of shared pcre, pcreposix or pcrs dnl libraried is now autodetected. Additionally, the dnl user can enforce using the built-in static variants dnl by specifying --disable-dynamic-(pcre|pcrs). dnl Care is taken to avoid that pcre is dyn, while pcreposix dnl is static, if both are used and that pcrs is static if dnl pcrs is. dnl dnl The choice between pcre, gnu or no regex for actionsfile dnl URL matching is now via dnl --(enable|disable)-regex-matching[=(gnu|pcre|no)] with the dnl default being pcre. dnl dnl Revision 1.6 2001/06/29 21:56:40 oes dnl Version -> 2.9.5 dnl dnl Revision 1.5 2001/06/29 13:26:27 oes dnl Introduced #define CODE_STATUS dnl dnl Revision 1.4 2001/05/29 09:50:24 jongfoster dnl Unified blocklist/imagelist/permissionslist. dnl File format is still under discussion, but the internal changes dnl are (mostly) done. dnl dnl Also modified interceptor behaviour: dnl - We now intercept all URLs beginning with one of the following dnl prefixes (and *only* these prefixes): dnl * http://i.j.b/ dnl * http://ijbswa.sf.net/config/ dnl * http://ijbswa.sourceforge.net/config/ dnl - New interceptors "home page" - go to http://i.j.b/ to see it. dnl - Internal changes so that intercepted and fast redirect pages dnl are not replaced with an image. dnl - Interceptors now have the option to send a binary page direct dnl to the client. (i.e. ijb-send-banner uses this) dnl - Implemented show-url-info interceptor. (Which is why I needed dnl the above interceptors changes - a typical URL is dnl "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif". dnl The previous mechanism would not have intercepted that, and dnl if it had been intercepted then it then it would have replaced dnl it with an image.) dnl dnl Revision 1.3 2001/05/22 18:46:04 oes dnl dnl - Enabled filtering banners by size rather than URL dnl by adding patterns that replace all standard banner dnl sizes with the "Junkbuster" gif to the re_filterfile dnl dnl - Enabled filtering WebBugs by providing a pattern dnl which kills all 1x1 images dnl dnl - Added support for PCRE_UNGREEDY behaviour to pcrs, dnl which is selected by the (nonstandard and therefore dnl capital) letter 'U' in the option string. dnl It causes the quantifiers to be ungreedy by default. dnl Appending a ? turns back to greedy (!). dnl dnl - Added a new interceptor ijb-send-banner, which dnl sends back the "Junkbuster" gif. Without imagelist or dnl MSIE detection support, or if tinygif = 1, or the dnl URL isn't recognized as an imageurl, a lame HTML dnl explanation is sent instead. dnl dnl - Added new feature, which permits blocking remote dnl script redirects and firing back a local redirect dnl to the browser. dnl The feature is conditionally compiled, i.e. it dnl can be disabled with --disable-fast-redirects, dnl plus it must be activated by a "fast-redirects" dnl line in the config file, has its own log level dnl and of course wants to be displayed by show-proxy-args dnl Note: Boy, all the #ifdefs in 1001 locations and dnl all the fumbling with configure.in and acconfig.h dnl were *way* more work than the feature itself :-( dnl dnl - Because a generic redirect template was needed for dnl this, tinygif = 3 now uses the same. dnl dnl - Moved GIFs, and other static HTTP response templates dnl to project.h dnl dnl - Some minor fixes dnl dnl - Removed some >400 CRs again (Jon, you really worked dnl a lot! ;-) dnl dnl Revision 1.2 2001/05/20 01:21:20 jongfoster dnl Version 2.9.4 checkin. dnl - Merged popupfile and cookiefile, and added control over PCRS dnl filtering, in new "permissionsfile". dnl - Implemented LOG_LEVEL_FATAL, so that if there is a configuration dnl file error you now get a message box (in the Win32 GUI) rather dnl than the program exiting with no explanation. dnl - Made killpopup use the PCRS MIME-type checking and HTTP-header dnl skipping. dnl - Removed tabs from "config" dnl - Moved duplicated url parsing code in "loaders.c" to a new funcition. dnl - Bumped up version number. dnl dnl Revision 1.1.1.1 2001/05/15 13:58:50 oes dnl Initial import of version 2.9.3 source tree dnl dnl dnl ================================================================= dnl AutoConf Initialization dnl ================================================================= AC_REVISION($Revision: 1.13 $) AC_INIT(jcc.c) AC_CONFIG_HEADER(config.h) dnl ================================================================= dnl Application version number dnl ================================================================= VERSION_MAJOR=2 VERSION_MINOR=9 VERSION_POINT=8 CODE_STATUS="\"alpha\"" dnl CODE_STATUS can be "alpha", "beta", or "stable", and will be dnl used for CGI output dnl ================================================================= dnl Substitute the version numbers dnl ================================================================= AC_SUBST(VERSION_MAJOR) AC_SUBST(VERSION_MINOR) AC_SUBST(VERSION_POINT) dnl AC_DEFINE_UNQUOTED(VERSION_MAJOR,${VERSION_MAJOR}) AC_DEFINE_UNQUOTED(VERSION_MINOR,${VERSION_MINOR}) AC_DEFINE_UNQUOTED(VERSION_POINT,${VERSION_POINT}) AC_DEFINE_UNQUOTED(VERSION,"${VERSION_MAJOR}.${VERSION_MINOR}.${VERSION_POINT}") AC_DEFINE_UNQUOTED(CODE_STATUS,${CODE_STATUS}) dnl ================================================================= dnl Checks for programs needed to build. dnl ================================================================= AC_PROG_CC AC_PROG_CPP dnl AC_PROG_CXX dnl AC_PROG_INSTALL dnl AC_PROG_LN_S dnl AC_PROG_MAKE_SET dnl RANLIB is for PCRE: dnl AC_PROG_RANLIB dnl ================================================================= dnl Build type dnl ================================================================= dnl dnl Must do this first. dnl dnl Reason: This sets CFLAGS in order to switch the Cygwin compiler dnl into Cygwin or MinGW32 modes.
