So, it's time to do a real, live, * native OS/2 port. See defines for __EMX__ (the porting layer) vs. __OS2__ * (native). Both versions will work, but using __OS2__ offers multi-threading. * * Revision 1.24 2001/10/23 21:40:30 jongfoster * Added support for enable-edit-actions and enable-remote-toggle config * file options. * * Revision 1.23 2001/10/07 15:36:00 oes * Introduced new config option "buffer-limit" * * Revision 1.22 2001/09/22 16:36:59 jongfoster * Removing unused parameter fs from read_config_line() * * Revision 1.21 2001/09/16 17:10:43 jongfoster * Moving function savearg() here, since it was the only thing left in * showargs.c. * * Revision 1.20 2001/07/30 22:08:36 jongfoster * Tidying up #defines: * - All feature #defines are now of the form FEATURE_xxx * - Permanently turned off WIN_GUI_EDIT * - Permanently turned on WEBDAV and SPLIT_PROXY_ARGS * * Revision 1.19 2001/07/15 17:45:16 jongfoster * Removing some unused #includes * * Revision 1.18 2001/07/13 14:01:14 oes * - Removed all #ifdef PCRS * - Removed vim-settings * * Revision 1.17 2001/06/29 13:31:03 oes * - Improved comments * - Fixed (actionsfile) and sorted hashes * - Introduced admin_address and proxy-info-url * as config parameters * - Renamed config->proxy_args_invocation (which didn't have * the invocation but the options!) to config->proxy_args * - Various adaptions * - Removed logentry from cancelled commit * * Revision 1.16 2001/06/09 10:55:28 jongfoster * Changing BUFSIZ ==> BUFFER_SIZE * * Revision 1.15 2001/06/07 23:13:40 jongfoster * Merging ACL and forward files into config file. * Cosmetic: Sorting config file options alphabetically. * Cosmetic: Adding brief syntax comments to config file options. * * Revision 1.14 2001/06/07 14:46:25 joergs * Missing make_path() added for re_filterfile. * * Revision 1.13 2001/06/05 22:33:54 jongfoster * * Fixed minor memory leak. * Also now uses make_path to prepend the pathnames. * * Revision 1.12 2001/06/05 20:04:09 jongfoster * Now uses _snprintf() in place of snprintf() under Win32. * * Revision 1.11 2001/06/04 18:31:58 swa * files are now prefixed with either `confdir' or `logdir'. * `make redhat-dist' replaces both entries confdir and logdir * with redhat values * * Revision 1.10 2001/06/03 19:11:54 oes * introduced confdir option * * Revision 1.9 2001/06/01 20:06:24 jongfoster * Removed support for "tinygif" option - moved to actions file. * * Revision 1.8 2001/05/31 21:27:13 jongfoster * Removed many options from the config file and into the * "actions" file: add_forwarded, suppress_vanilla_wafer, * wafer, add_header, user_agent, referer, from * Also globally replaced "permission" with "action". * * Revision 1.7 2001/05/29 09:50:24 jongfoster * Unified blocklist/imagelist/permissionslist. * File format is still under discussion, but the internal changes * are (mostly) done. * * Also modified interceptor behaviour: * - We now intercept all URLs beginning with one of the following * prefixes (and *only* these prefixes): * * http://i.j.b/ * * http://ijbswa.sf.net/config/ * * http://ijbswa.sourceforge.net/config/ * - New interceptors "home page" - go to http://i.j.b/ to see it. * - Internal changes so that intercepted and fast redirect pages * are not replaced with an image. * - Interceptors now have the option to send a binary page direct * to the client. (i.e. ijb-send-banner uses this) * - Implemented show-url-info interceptor. (Which is why I needed * the above interceptors changes - a typical URL is * "http://i.j.b/show-url-info?url=www.somesite.com/banner.gif". * The previous mechanism would not have intercepted that, and * if it had been intercepted then it then it would have replaced * it with an image.) * * Revision 1.6 2001/05/26 00:28:36 jongfoster * Automatic reloading of config file. * Removed obsolete SIGHUP support (Unix) and Reload menu option (Win32). * Most of the global variables have been moved to a new * struct configuration_spec, accessed through csp->config->globalname * Most of the globals remaining are used by the Win32 GUI. * * Revision 1.5 2001/05/25 22:34:30 jongfoster * Hard tabs->Spaces * * Revision 1.4 2001/05/22 18:46:04 oes * * - Enabled filtering banners by size rather than URL * by adding patterns that replace all standard banner * sizes with the "Junkbuster" gif to the re_filterfile * * - Enabled filtering WebBugs by providing a pattern * which kills all 1x1 images * * - Added support for PCRE_UNGREEDY behaviour to pcrs, * which is selected by the (nonstandard and therefore * capital) letter 'U' in the option string. * It causes the quantifiers to be ungreedy by default. * Appending a ? turns back to greedy (!). * * - Added a new interceptor ijb-send-banner, which * sends back the "Junkbuster" gif. Without imagelist or * MSIE detection support, or if tinygif = 1, or the * URL isn't recognized as an imageurl, a lame HTML * explanation is sent instead. * * - Added new feature, which permits blocking remote * script redirects and firing back a local redirect * to the browser. * The feature is conditionally compiled, i.e. it * can be disabled with --disable-fast-redirects, * plus it must be activated by a "fast-redirects" * line in the config file, has its own log level * and of course wants to be displayed by show-proxy-args * Note: Boy, all the #ifdefs in 1001 locations and * all the fumbling with configure.in and acconfig.h * were *way* more work than the feature itself :-( * * - Because a generic redirect template was needed for * this, tinygif = 3 now uses the same. * * - Moved GIFs, and other static HTTP response templates * to project.h * * - Some minor fixes * * - Removed some >400 CRs again (Jon, you really worked * a lot! ;-) * * Revision 1.3 2001/05/20 01:21:20 jongfoster * Version 2.9.4 checkin. * - Merged popupfile and cookiefile, and added control over PCRS * filtering, in new "permissionsfile". * - Implemented LOG_LEVEL_FATAL, so that if there is a configuration * file error you now get a message box (in the Win32 GUI) rather * than the program exiting with no explanation. * - Made killpopup use the PCRS MIME-type checking and HTTP-header * skipping. * - Removed tabs from "config" * - Moved duplicated url parsing code in "loaders.c" to a new funcition. * - Bumped up version number. * * Revision 1.2 2001/05/17 23:01:01 oes * - Cleaned CRLF's from the sources and related files * * Revision 1.1.1.1 2001/05/15 13:58:58 oes * Initial import of version 2.9.3 source tree * * *********************************************************************/ #include "config.h" #include #include #include #include #include #include #include #include #include #ifdef _WIN32 # include # include "win32.h" # ifndef _WIN_CONSOLE # include "w32log.h" # endif /* ndef _WIN_CONSOLE */ /* VC++ has "_snprintf", not "snprintf" */ #define snprintf _snprintf #else /* ifndef _WIN32 */ #ifndef __OS2__ # include # include #endif # include # include # include #endif #include "loadcfg.h" #include "list.h" #include "jcc.h" #include "filters.h" #include "loaders.h" #include "miscutil.h" #include "errlog.h" #include "ssplit.h" #include "encode.h" #include "urlmatch.h" const char loadcfg_h_rcs[] = LOADCFG_H_VERSION; /* * Fix a problem with Solaris.
