44 * New, buggy versions of event editing screens

59 * Presentation changes to calendar month view

72 Revision 400.18 2002/09/20 03:54:44 ajc
73 * Display the "Tasks" view as a bulleted list with each task clickable

99 Revision 400.11 2002/09/15 03:16:24 ajc
100 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
101 function namespace in libical
103 Revision 400.10 2002/09/15 02:50:55 ajc
104 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
106 Revision 400.9 2002/09/14 21:33:31 ajc
107 * Backed out compression of inlines -- not all browsers appear to handle it
109 Revision 400.8 2002/09/14 20:20:29 ajc
110 * Attempting to push more stuff through compression. I've introduced some
111 sort of deadlock bug that I can't seem to find yet...

114 * Compress output_image() graphics
116 Revision 400.6 2002/09/14 16:26:35 ajc
117 * output_image() now reads the entire image from Citadel into a buffer before

128 (actual encoding is not implemented yet)

145 * Added an "About this server" panel to the Summary page.
146 (Useless fluff, but better than an empty column.)

211 Revision 323.46 2002/07/13 04:39:59 ajc
212 * Handle multipart/alternative in a nicer way, giving us the opportunity to
213 output HTML instead of converting to text/plain and back. (Not finished.)
215 Revision 323.45 2002/07/11 03:17:03 ajc
216 * hacks to text_to_server() to transmit messages as HTML

493 queue length to 100 for use on big systems. Also, during startup, the
494 initial startup thread now exits after creating the worker threads, instead
495 of becoming a worker thread itself. For some reason Solaris had problems

575 Revision 212.15 2000/09/28 03:44:52 ajc

629 Revision 211.19 2000/05/18 02:33:39 ajc

651 Revision 211.14 2000/04/15 15:43:46 nbryant
652 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

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

777 * Per Nick's request, removed the key bindings stuff. He knows how to fit

782 * Merged in Nick's bit of JavaScript to handle key commands.
783 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is

838 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

844 the transition back to the Lobby after it's all done.
845 * Added ExpressMessageCat() to allow code to send the user messages
846 along with incoming express messages
847 * WebCit now sends the name of the end user's browser as the client

862 * Replaced _most_ gotoroom() calls with smart_goto(), a version

881 in urls so GOTOs and User Profiles work when the string has a
884 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
885 http://www.webreference.com/dhtml/column18/menuFrLoad.html
886 How to cause "onLoad=" to cause a sibling frame to refresh without
887 having to use the nonportable HTTP "Window-Target:" directive. Began
888 implementation of this; it should allow portable NS/IE compatibility.

894 * webcit.c: modified getz() to *exit* the program when fgets()
895 returns an error. This is actually the desired behavior; it would
896 otherwise busy-loop forever on a broken pipe.
898 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

903 * wildmat.c, braindamage.c: added
904 * Initial value of 'noframes' is now set by the braindamage check
905 * Ran everything through "indent -kr -i8"
906 * roomops.c: in room list, print a in otherwise empty cells
908 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>

912 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
913 * Resolve the name of the connecting host and pass it on to Citadel
915 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
916 * wDumpContent() is now responsible for </BODY></HTML> most of the
917 time (parameter settable) so that the main menu can easily be
918 embedded in every page when running in noframes mode
919 * noframes mode selection is now carried in the cookie
921 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
922 * Made the frames stuff less dependent on the HTML TARGET= directive
923 and more dependent on the HTTP Window-target: directive.
924 * Made the system semi-navigable in noframes mode.
926 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

928 from the main Citadel tree, to pay attention to floor/room ordering
930 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
931 * Modified the back end of mime_parser to use callbacks instead of
932 doing something specific. Now we can use it elsewhere.
934 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

947 * Set up automatic trigger of Enter Registration when the server
949 * Established that a one-to-one WebCit/Citadel correspondence will
950 be required. No big deal due to shared code segments.
951 * Added "change password"
952 * Added networking configuration screens. These still need testing.
953 * Added a "kill session" link to each line of the wholist when
954 logged in as an aide, and the screens to perform this operation.
956 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

980 to an "onload" directive (the former was causing graphics problems)

1001 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1002 * context_loop.c: Moved "remove session" into its own function.
1003 Check for dead webcit child process before each transaction.
1004 * Ignore SIGPIPE; this seems to magically make the program bulletproof
1005 against broken HTTP connections.
1006 * Added a housekeeping thread to periodically remove dead sessions
1007 and kill idle sessions.
1008 * messages.c: added "delete message" functionality
1009 * messages.c: added "move message" functionality

1023 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1024 * context_loop.c: After fork(), child process closes the HTTP socket
1025 so when the parent process closes it, it actually _does_ close.
1026 Otherwise, aIEeeee and possibly other browsers will hang.
1027 * Added support for graphics images retrieved from the Citadel server.
1028 * Set up login banner graphic and background image graphic
1030 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

1033 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1034 * Smoothed out some of the login/logout code. Failed authentication
1035 now works the way it should.
1036 * Added support for new user login (still need to handle registration).
1038 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1039 * Discovered that the HTTP socket problem is related to a socket that
1040 isn't properly lingering on close. Temporarily hacked a sleep(10)
1041 into context_loop.c until it is figured out.
1043 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1044 * Did a little debugging, still trying to figure out why logging in
1045 displays "Connection reset by peer" error. It used to work...
1047 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
1048 * Makefile.in: updated dependencies
1050 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1052 * added new "action" variable to make main loop simpler
1054 1998-12-06 Nathan Bryant <bryant@cs.usm.maine.edu>

1056 * context_loop.c: warning fix
1058 1998-12-05 Nathan Bryant <bryant@cs.usm.maine.edu>

1065 * webserver.c, context_loop.c, webcit.c: add commandline args for host
1067 * converted to autoconf and began port to Digital UNIX
1069 * context_loop.c: moved the monster 64k buffer array off the stack
1070 * tcp_sockets.c: getservbyname() doesn't set errno.
1072 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
1073 * webserver.c: warning fix
