- * Revision 1.87 2002/03/26 22:29:54 swa
- * we have a new homepage!
- *
- * Revision 1.86 2002/03/25 17:04:55 david__schmidt
- * Workaround for closing the jarfile before load_config() comes around again
- *
- * Revision 1.85 2002/03/24 15:23:33 jongfoster
- * Name changes
- *
- * Revision 1.84 2002/03/24 13:25:43 swa
- * name change related issues
- *
- * Revision 1.83 2002/03/16 23:54:06 jongfoster
- * Adding graceful termination feature, to help look for memory leaks.
- * If you enable this (which, by design, has to be done by hand
- * editing config.h) and then go to http://i.j.b/die, then the program
- * will exit cleanly after the *next* request. It should free all the
- * memory that was used.
- *
- * Revision 1.82 2002/03/13 00:27:05 jongfoster
- * Killing warnings
- *
- * Revision 1.81 2002/03/12 01:42:50 oes
- * Introduced modular filters
- *
- * Revision 1.80 2002/03/11 22:07:05 david__schmidt
- * OS/2 port maintenance:
- * - Fixed EMX build - it had decayed a little
- * - Fixed inexplicable crash during FD_ZERO - must be due to a bad macro.
- * substituted a memset for now.
- *
- * Revision 1.79 2002/03/09 20:03:52 jongfoster
- * - Making various functions return int rather than size_t.
- * (Undoing a recent change). Since size_t is unsigned on
- * Windows, functions like read_socket that return -1 on
- * error cannot return a size_t.
- *
- * THIS WAS A MAJOR BUG - it caused frequent, unpredictable
- * crashes, and also frequently caused JB to jump to 100%
- * CPU and stay there. (Because it thought it had just
- * read ((unsigned)-1) == 4Gb of data...)
- *
- * - The signature of write_socket has changed, it now simply
- * returns success=0/failure=nonzero.
- *
- * - Trying to get rid of a few warnings --with-debug on
- * Windows, I've introduced a new type "jb_socket". This is
- * used for the socket file descriptors. On Windows, this
- * is SOCKET (a typedef for unsigned). Everywhere else, it's
- * an int. The error value can't be -1 any more, so it's
- * now JB_INVALID_SOCKET (which is -1 on UNIX, and in
- * Windows it maps to the #define INVALID_SOCKET.)
- *
- * - The signature of bind_port has changed.
- *
- * Revision 1.78 2002/03/08 21:35:04 oes
- * Added optional group supplement to --user option. Will now use default group of user if no group given
- *
- * Revision 1.77 2002/03/07 03:52:06 oes
- * - Fixed compiler warnings etc
- * - Improved handling of failed DNS lookups
- *
- * Revision 1.76 2002/03/06 22:54:35 jongfoster
- * Automated function-comment nitpicking.
- *
- * Revision 1.75 2002/03/06 10:02:19 oes
- * Fixed stupid bug when --user was not given
- *
- * Revision 1.74 2002/03/06 00:49:31 jongfoster
- * Fixing warning on Windows
- * Making #ifdefs that refer to the same variable consistently
- * use #ifdef unix rather than mixing #ifdef unix & #ifndef OS2
- *
- * Revision 1.73 2002/03/05 23:57:30 hal9
- * Stray character 's' on line 1618 was breaking build.

- * - Re-enable OS/2 building after new parms were added
- * - Fix false out of memory report when resolving CGI templates when no IP
- * address is available of failed attempt (a la no such domain)
- *
- * Revision 1.71 2002/03/05 18:13:56 oes

- *
- * Revision 1.67 2002/03/04 18:18:57 oes

- *

- * Fixing type mismatch
- *
- * Revision 1.51 2001/10/26 17:38:28 oes
- * Cosmetics
- *
- * Revision 1.50 2001/10/25 03:40:48 david__schmidt
- * Change in porting tactics: OS/2's EMX porting layer doesn't allow multiple
- * threads to call select() simultaneously. 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 1.49 2001/10/23 21:41:35 jongfoster
- * Added call to initialize the (statically-allocated of course)
- * "out of memory" CGI response.
- *
- * Revision 1.48 2001/10/10 19:56:46 jongfoster
- * Moving some code that wasn't cookie-related out of an #ifdef
- * FEATURE_COOKIE_JAR
- *
- * Revision 1.47 2001/10/10 16:44:36 oes
- * Added CONNECT destination port limitation check
- *
- * Revision 1.46 2001/10/08 15:17:41 oes
- * Re-enabled SSL forwarding
- *
- * Revision 1.45 2001/10/07 15:42:11 oes
- * Replaced 6 boolean members of csp with one bitmap (csp->flags)
- *
- * Moved downgrading of the HTTP version from parse_http_request to
- * chat(), since we can't decide if it is necessary before we have
- * determined the actions for the URL. The HTTP command is now
- * *always* re-built so the repairs need no longer be special-cased.
- *
- * filter_popups now gets a csp pointer so it can raise the new
- * CSP_FLAG_MODIFIED flag.
- *
- * Bugfix
- *
- * Added configurable size limit for the IOB. If the IOB grows so
- * large that the next read would exceed the limit, the header
- * is generated, and the header & unfiltered buffer are flushed
- * to the client. Chat then continues in non-buffering,
- * non-filtering body mode.
- *
- * Revision 1.44 2001/10/02 18:13:57 oes
- * Ooops
- *
- * Revision 1.43 2001/10/02 15:32:13 oes
- * Moved generation of hdr
- *
- * Revision 1.42 2001/09/21 23:02:02 david__schmidt

- *
- * Revision 1.41 2001/09/16 17:05:14 jongfoster
- * Removing unused #include showarg.h
- *
- * Revision 1.40 2001/09/16 15:41:45 jongfoster
- * Fixing signed/unsigned comparison warning.
- *
- * Revision 1.39 2001/09/16 13:21:27 jongfoster
- * Changes to use new list functions.
- *
- * Revision 1.38 2001/09/16 13:01:46 jongfoster
- * Removing redundant function call that zeroed zalloc()'d memory.
- *
- * Revision 1.37 2001/09/10 11:12:24 oes
- * Deleted unused variable
- *
- * Revision 1.36 2001/09/10 10:56:15 oes
- * Silenced compiler warnings
- *
- * Revision 1.35 2001/07/31 14:44:22 oes
- * Deleted unused size parameter from filter_popups()
- *
- * Revision 1.34 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 1.33 2001/07/29 19:32:00 jongfoster
- * Renaming _main() [mingw32 only] to real_main(), for ANSI compliance.
- *
- * Revision 1.32 2001/07/29 18:47:05 jongfoster
- * Adding missing #include "loadcfg.h"
- *
- * Revision 1.31 2001/07/29 12:17:48 oes
- * Applied pthread fix by Paul Lieverse
- *
- * Revision 1.30 2001/07/25 22:57:13 jongfoster
- * __BEOS__ no longer overrides FEATURE_PTHREAD.
- * This is because FEATURE_PTHREAD will soon be widely used, so I
- * want to keep it simple.
- *
- * Revision 1.29 2001/07/24 12:47:06 oes
- * Applied BeOS support update by Eugenia
- *
- * Revision 1.28 2001/07/23 13:26:12 oes
- * Fixed bug in popup-killing for the first read that caused binary garbage to be sent between headers and body
- *
- * Revision 1.27 2001/07/19 19:09:47 haroon
- * - Added code to take care of the situation where while processing the first
- * server response (which includes the server header), after finding the end
- * of the headers we were not looking past the end of the headers for
- * content modification. I enabled it for filter_popups.
- * Someone else should look to see if other similar operations should be
- * done to the discarded portion of the buffer.
- *
- * Note 2001/07/20: No, the other content modification mechanisms will process
- * the whole iob later anyway. --oes
