47 Revision 400.22 2002/09/23 04:01:33 ajc
48 * Presentation changes to calendar month view

88 Revision 400.11 2002/09/15 03:16:24 ajc
89 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
90 function namespace in libical
92 Revision 400.10 2002/09/15 02:50:55 ajc
93 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
95 Revision 400.9 2002/09/14 21:33:31 ajc
96 * Backed out compression of inlines -- not all browsers appear to handle it
98 Revision 400.8 2002/09/14 20:20:29 ajc
99 * Attempting to push more stuff through compression. I've introduced some
100 sort of deadlock bug that I can't seem to find yet...
102 Revision 400.7 2002/09/14 20:00:22 ajc
103 * Compress output_image() graphics
105 Revision 400.6 2002/09/14 16:26:35 ajc
106 * output_image() now reads the entire image from Citadel into a buffer before

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

200 Revision 323.46 2002/07/13 04:39:59 ajc
201 * Handle multipart/alternative in a nicer way, giving us the opportunity to
202 output HTML instead of converting to text/plain and back. (Not finished.)

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

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

618 Revision 211.19 2000/05/18 02:33:39 ajc
619 * Don't call whobbs() directly after changing masq room/host, it screws up the
620 refresh. It now calls an HTTP redirect page instead.

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

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

638 big session logjams when either of these conditions are met
640 Revision 211.14 2000/04/15 15:43:46 nbryant
641 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

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

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

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

831 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
832 * Fixed the behavior of the "forget room" routine, to properly handle
833 the transition back to the Lobby after it's all done.
834 * Added ExpressMessageCat() to allow code to send the user messages
835 along with incoming express messages
836 * WebCit now sends the name of the end user's browser as the client
837 name in a Citadel IDEN command rather than its own name.
839 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
840 * Minor code cleanups

846 Fri May 14 23:37:02 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
847 * Initial entry to _BASEROOM_ at login now done as a Skip instead

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

869 Changed who.c to use urlescputs() rather than escputs()
870 in urls so GOTOs and User Profiles work when the string has a
873 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
874 http://www.webreference.com/dhtml/column18/menuFrLoad.html
875 How to cause "onLoad=" to cause a sibling frame to refresh without
876 having to use the nonportable HTTP "Window-Target:" directive. Began
877 implementation of this; it should allow portable NS/IE compatibility.
879 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
880 * Implemented "access level required to create rooms"

883 * webcit.c: modified getz() to *exit* the program when fgets()
884 returns an error. This is actually the desired behavior; it would
885 otherwise busy-loop forever on a broken pipe.
887 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
888 * webcit.c: added to getz() the ability to return an error code;
889 implemented this in the main loop, hopefully fixing problems

891 * Added HTTP "User-agent:" detection
892 * wildmat.c, braindamage.c: added
893 * Initial value of 'noframes' is now set by the braindamage check
894 * Ran everything through "indent -kr -i8"
895 * roomops.c: in room list, print a in otherwise empty cells
897 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
898 * context_loop.c: warning fix
899 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
901 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
902 * Resolve the name of the connecting host and pass it on to Citadel
904 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
905 * wDumpContent() is now responsible for </BODY></HTML> most of the
906 time (parameter settable) so that the main menu can easily be
907 embedded in every page when running in noframes mode

910 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
911 * Made the frames stuff less dependent on the HTML TARGET= directive
912 and more dependent on the HTTP Window-target: directive.

919 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
920 * Modified the back end of mime_parser to use callbacks instead of

936 * Set up automatic trigger of Enter Registration when the server
938 * Established that a one-to-one WebCit/Citadel correspondence will
939 be required. No big deal due to shared code segments.
940 * Added "change password"
941 * Added networking configuration screens. These still need testing.
942 * Added a "kill session" link to each line of the wholist when
943 logged in as an aide, and the screens to perform this operation.

968 * Changed the "auto read new" functionality from a meta refresh tag
969 to an "onload" directive (the former was causing graphics problems)

990 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
991 * context_loop.c: Moved "remove session" into its own function.
992 Check for dead webcit child process before each transaction.
993 * Ignore SIGPIPE; this seems to magically make the program bulletproof
994 against broken HTTP connections.
995 * Added a housekeeping thread to periodically remove dead sessions
996 and kill idle sessions.
997 * messages.c: added "delete message" functionality
998 * messages.c: added "move message" functionality

1012 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1013 * context_loop.c: After fork(), child process closes the HTTP socket
1014 so when the parent process closes it, it actually _does_ close.
1015 Otherwise, aIEeeee and possibly other browsers will hang.
1016 * Added support for graphics images retrieved from the Citadel server.
1017 * Set up login banner graphic and background image graphic
1019 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

1022 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1023 * Smoothed out some of the login/logout code. Failed authentication
1024 now works the way it should.
1025 * Added support for new user login (still need to handle registration).
1027 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1028 * Discovered that the HTTP socket problem is related to a socket that
1029 isn't properly lingering on close. Temporarily hacked a sleep(10)
1030 into context_loop.c until it is figured out.
1032 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1033 * Did a little debugging, still trying to figure out why logging in
1034 displays "Connection reset by peer" error. It used to work...
1036 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
1037 * Makefile.in: updated dependencies
1039 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1054 * webserver.c, context_loop.c, webcit.c: add commandline args for host
1056 * converted to autoconf and began port to Digital UNIX
1058 * context_loop.c: moved the monster 64k buffer array off the stack
1059 * tcp_sockets.c: getservbyname() doesn't set errno.
1061 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
1062 * webserver.c: warning fix
