115 * Handle multipart/alternative in a nicer way, giving us the opportunity to

353 * Added the "-c" command line option to generate optional cookies indicating

396 queue length to 100 for use on big systems. Also, during startup, the
397 initial startup thread now exits after creating the worker threads, instead
398 of becoming a worker thread itself. For some reason Solaris had problems
399 with the latter method.

530 * Tagged for the 2.12 release
532 Revision 211.19 2000/05/18 02:33:39 ajc
533 * Don't call whobbs() directly after changing masq room/host, it screws up the
534 refresh. It now calls an HTTP redirect page instead.

537 Revision 211.18 2000/05/08 17:24:32 ajc
538 * Removed HTTP date fields because it was confusing browser caches (weird)

548 Revision 211.15 2000/04/20 02:42:23 ajc

551 * End the session after displaying robots.txt or nocookies.html, to prevent
552 big session logjams when either of these conditions are met
554 Revision 211.14 2000/04/15 15:43:46 nbryant
555 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

645 Revision 1.111 1999/12/03 17:59:53 ajc
646 * BROKEN BUILD. Wrote most of the session removal code, but some of it is

679 Revision 1.101 1999/10/06 02:44:02 ajc
680 * Per Nick's request, removed the key bindings stuff. He knows how to fit
681 it back in when it's fixed. Also added more attempts at cache disabling,
682 but it still doesn't work in the StarOffice browser. I don't know why.
684 Revision 1.100 1999/10/02 03:26:14 ajc
685 * Merged in Nick's bit of JavaScript to handle key commands.
686 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is

750 * WebCit now sends the name of the end user's browser as the client

788 http://www.webreference.com/dhtml/column18/menuFrLoad.html
789 How to cause "onLoad=" to cause a sibling frame to refresh without
790 having to use the nonportable HTTP "Window-Target:" directive. Began
791 implementation of this; it should allow portable NS/IE compatibility.

797 * webcit.c: modified getz() to *exit* the program when fgets()
798 returns an error. This is actually the desired behavior; it would
799 otherwise busy-loop forever on a broken pipe.

806 * wildmat.c, braindamage.c: added
807 * Initial value of 'noframes' is now set by the braindamage check

811 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
812 * context_loop.c: warning fix
813 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
815 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
816 * Resolve the name of the connecting host and pass it on to Citadel
818 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
819 * wDumpContent() is now responsible for </BODY></HTML> most of the
820 time (parameter settable) so that the main menu can easily be
821 embedded in every page when running in noframes mode
822 * noframes mode selection is now carried in the cookie
824 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

831 from the main Citadel tree, to pay attention to floor/room ordering
833 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
834 * Modified the back end of mime_parser to use callbacks instead of
835 doing something specific. Now we can use it elsewhere.
837 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
838 * Fixed the bugs in "Site-wide configuration"

849 * Added "enter registration"
850 * Set up automatic trigger of Enter Registration when the server
852 * Established that a one-to-one WebCit/Citadel correspondence will
853 be required. No big deal due to shared code segments.
854 * Added "change password"
855 * Added networking configuration screens. These still need testing.
856 * Added a "kill session" link to each line of the wholist when
857 logged in as an aide, and the screens to perform this operation.

901 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
902 * automatically regenerate Makefile when Makefile.in changes
904 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
905 * context_loop.c: Moved "remove session" into its own function.
906 Check for dead webcit child process before each transaction.
907 * Ignore SIGPIPE; this seems to magically make the program bulletproof
908 against broken HTTP connections.
909 * Added a housekeeping thread to periodically remove dead sessions
910 and kill idle sessions.
911 * messages.c: added "delete message" functionality
912 * messages.c: added "move message" functionality
913 * userlist.c: added. This adds "userlist" and "show user" functions.
914 * roomops.c: fixed buggy implementation of ungoto
915 * Set up an option in output_headers() to optionally print the most
916 often used opening HTML as well as the HTTP headers.
917 * Display express messages in cute little JavaScript popup window.
919 Fri Dec 11 21:14:36 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
920 * Brought over message reading and entry functions from old WebCit
922 1998-12-10 Nathan Bryant <bryant@cs.usm.maine.edu>
923 * context_loop.c: really fix the SO_LINGER stuff
924 * webserver.c: remove commented-out references to SO_LINGER
926 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
927 * context_loop.c: After fork(), child process closes the HTTP socket
928 so when the parent process closes it, it actually _does_ close.
929 Otherwise, aIEeeee and possibly other browsers will hang.
930 * Added support for graphics images retrieved from the Citadel server.
931 * Set up login banner graphic and background image graphic
933 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
934 * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix
936 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
937 * Smoothed out some of the login/logout code. Failed authentication
938 now works the way it should.
939 * Added support for new user login (still need to handle registration).
941 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
942 * Discovered that the HTTP socket problem is related to a socket that
943 isn't properly lingering on close. Temporarily hacked a sleep(10)
944 into context_loop.c until it is figured out.
946 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
947 * Did a little debugging, still trying to figure out why logging in
948 displays "Connection reset by peer" error. It used to work...
950 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
951 * Makefile.in: updated dependencies
953 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
954 * Fixed broken interpretation of variables specified in the URL
955 * added new "action" variable to make main loop simpler
957 1998-12-06 Nathan Bryant <bryant@cs.usm.maine.edu>
958 * webserver.c: prototype vsnprintf
959 * context_loop.c: warning fix
961 1998-12-05 Nathan Bryant <bryant@cs.usm.maine.edu>
962 * tcp_sockets.c: removed some dead code
963 * context_loop.c: oops, I made a memory leak. fix fix fix. also close
964 unused ends of pipes, fix a file descriptor leak and a race condition
965 * portability enhancements
967 1998-12-04 Nathan Bryant <bryant@cs.usm.maine.edu>
968 * webserver.c, context_loop.c, webcit.c: add commandline args for host
970 * converted to autoconf and began port to Digital UNIX
972 * context_loop.c: moved the monster 64k buffer array off the stack
973 * tcp_sockets.c: getservbyname() doesn't set errno.
975 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
976 * webserver.c: warning fix
