6 * Implemented a 'display handler' infrastructure for various groupware types
8 Revision 400.14 2002/09/16 03:35:12 ajc
9 * Just a bunch of glue code to iterate through the various types of ical
10 objects we could encounter
12 Revision 400.13 2002/09/15 04:05:41 ajc
13 * Process calendar object subcomponents
15 Revision 400.12 2002/09/15 03:40:13 ajc
17 * When a text/calendar MIME type is discovered in a message, send it to
18 the (currently skeleton) parser in calendar.c
19 * calendar.c: skeleton parser for calendar objects which currently just
20 creates an icalcomponent object and frees it.
22 Revision 400.11 2002/09/15 03:16:24 ajc
23 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with

29 Revision 400.9 2002/09/14 21:33:31 ajc

32 Revision 400.8 2002/09/14 20:20:29 ajc

34 sort of deadlock bug that I can't seem to find yet...

37 * Compress output_image() graphics
39 Revision 400.6 2002/09/14 16:26:35 ajc
40 * output_image() now reads the entire image from Citadel into a buffer before
41 sending it to the browser (for performance reasons, and so it can compress)
43 Revision 400.5 2002/09/14 04:52:59 ajc

67 Revision 323.67 2002/09/06 03:59:11 ajc
68 * Added an "About this server" panel to the Summary page.
69 (Useless fluff, but better than an empty column.)
71 Revision 323.66 2002/08/26 02:57:06 ajc
72 * Rooms listed on the summary page are now clickable-gotoable
74 Revision 323.65 2002/08/26 01:24:09 ajc

77 Revision 323.64 2002/08/24 15:30:48 ajc

100 * Fleshed out the list subscription page a bit
102 Revision 323.56 2002/08/13 19:55:12 ajc

134 Revision 323.46 2002/07/13 04:39:59 ajc
135 * Handle multipart/alternative in a nicer way, giving us the opportunity to
136 output HTML instead of converting to text/plain and back. (Not finished.)
138 Revision 323.45 2002/07/11 03:17:03 ajc
139 * hacks to text_to_server() to transmit messages as HTML
141 Revision 323.44 2002/07/09 04:21:12 ajc

307 Revision 320.2 2001/12/26 05:24:11 ajc

373 * Added the "-c" command line option to generate optional cookies indicating
374 the host name of the server. This makes it easy to put a cluster of WebCit
375 servers behind (for example) an Arrowpoint load balancer.
377 Revision 301.5 2001/08/21 04:02:56 ajc
378 * Added some more meta-tags to (hopefully) prevent the "lame goto" caused by
379 unwanted page caching
381 Revision 301.4 2001/08/13 03:43:24 ajc
384 Revision 301.3 2001/08/13 03:40:01 ajc

416 queue length to 100 for use on big systems. Also, during startup, the
417 initial startup thread now exits after creating the worker threads, instead
418 of becoming a worker thread itself. For some reason Solaris had problems
419 with the latter method.
421 Revision 213.22 2001/06/07 03:16:57 ajc
422 * Brought over an updated mime parser from Citadel

552 Revision 211.19 2000/05/18 02:33:39 ajc
553 * Don't call whobbs() directly after changing masq room/host, it screws up the

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

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

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

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

769 along with incoming express messages
770 * WebCit now sends the name of the end user's browser as the client

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

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

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

831 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
832 * context_loop.c: warning fix
833 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
835 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
836 * Resolve the name of the connecting host and pass it on to Citadel
838 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
839 * wDumpContent() is now responsible for </BODY></HTML> most of the
840 time (parameter settable) so that the main menu can easily be
841 embedded in every page when running in noframes mode
842 * noframes mode selection is now carried in the cookie
844 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

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

865 * Removed wc_host and wc_port cookies.
866 * Added an "edit your session" screen to change your wholisting.

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

888 Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
889 * Wrote mime_parser.c for handling of image uploads. This will also
890 be used in future Citadel MIME projects.

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

918 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

921 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
922 * automatically regenerate Makefile when Makefile.in changes
924 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
925 * context_loop.c: Moved "remove session" into its own function.
926 Check for dead webcit child process before each transaction.
927 * Ignore SIGPIPE; this seems to magically make the program bulletproof
928 against broken HTTP connections.
929 * Added a housekeeping thread to periodically remove dead sessions
930 and kill idle sessions.
931 * messages.c: added "delete message" functionality
932 * messages.c: added "move message" functionality
933 * userlist.c: added. This adds "userlist" and "show user" functions.
934 * roomops.c: fixed buggy implementation of ungoto
935 * Set up an option in output_headers() to optionally print the most
936 often used opening HTML as well as the HTTP headers.
937 * Display express messages in cute little JavaScript popup window.
939 Fri Dec 11 21:14:36 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

946 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
947 * context_loop.c: After fork(), child process closes the HTTP socket
948 so when the parent process closes it, it actually _does_ close.
949 Otherwise, aIEeeee and possibly other browsers will hang.
950 * Added support for graphics images retrieved from the Citadel server.
951 * Set up login banner graphic and background image graphic
953 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
954 * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix
956 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
957 * Smoothed out some of the login/logout code. Failed authentication
958 now works the way it should.
959 * Added support for new user login (still need to handle registration).
961 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
962 * Discovered that the HTTP socket problem is related to a socket that
963 isn't properly lingering on close. Temporarily hacked a sleep(10)
964 into context_loop.c until it is figured out.
966 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
967 * Did a little debugging, still trying to figure out why logging in
968 displays "Connection reset by peer" error. It used to work...
970 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
971 * Makefile.in: updated dependencies
973 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
974 * Fixed broken interpretation of variables specified in the URL
975 * added new "action" variable to make main loop simpler
977 1998-12-06 Nathan Bryant <bryant@cs.usm.maine.edu>
978 * webserver.c: prototype vsnprintf
979 * context_loop.c: warning fix
981 1998-12-05 Nathan Bryant <bryant@cs.usm.maine.edu>
982 * tcp_sockets.c: removed some dead code

990 * converted to autoconf and began port to Digital UNIX
992 * context_loop.c: moved the monster 64k buffer array off the stack
993 * tcp_sockets.c: getservbyname() doesn't set errno.
995 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
996 * webserver.c: warning fix
