10 * New, buggy versions of event editing screens
12 Revision 400.25 2002/09/26 22:00:16 ajc

16 Revision 400.24 2002/09/25 21:57:13 ajc
17 * Keep track of msgnums in the two-pass calendar loop, so we can hotlink to
20 Revision 400.23 2002/09/24 04:12:34 ajc
21 * Rough cut of the two-pass calendar display routines (first pass: go thru
22 messages gathering VEVENT items; second pass: render calendar with data)
24 Revision 400.22 2002/09/23 04:01:33 ajc
25 * Presentation changes to calendar month view
27 Revision 400.21 2002/09/22 05:20:27 ajc

30 Revision 400.20 2002/09/21 04:38:05 ajc
31 * Added utility functions for displaying vcalendar timestamps in web forms
32 and translating form data back to timestamps.
33 * Completed the "edit task" and "add new task" screens.
35 Revision 400.19 2002/09/20 20:28:08 ajc
36 * Smooth transition between "list tasks" & "edit task" screens
38 Revision 400.18 2002/09/20 03:54:44 ajc
39 * Display the "Tasks" view as a bulleted list with each task clickable
40 * Clicking brings up an (unfinished) "edit task" screen

48 Revision 400.15 2002/09/17 03:37:10 ajc
49 * Implemented a 'display handler' infrastructure for various groupware types
51 Revision 400.14 2002/09/16 03:35:12 ajc

56 * Process calendar object subcomponents
58 Revision 400.12 2002/09/15 03:40:13 ajc
60 * When a text/calendar MIME type is discovered in a message, send it to

63 creates an icalcomponent object and frees it.
65 Revision 400.11 2002/09/15 03:16:24 ajc
66 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
67 function namespace in libical
69 Revision 400.10 2002/09/15 02:50:55 ajc
70 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
72 Revision 400.9 2002/09/14 21:33:31 ajc
73 * Backed out compression of inlines -- not all browsers appear to handle it
75 Revision 400.8 2002/09/14 20:20:29 ajc
76 * Attempting to push more stuff through compression. I've introduced some
77 sort of deadlock bug that I can't seem to find yet...
79 Revision 400.7 2002/09/14 20:00:22 ajc
80 * Compress output_image() graphics
82 Revision 400.6 2002/09/14 16:26:35 ajc
83 * output_image() now reads the entire image from Citadel into a buffer before
84 sending it to the browser (for performance reasons, and so it can compress)
86 Revision 400.5 2002/09/14 04:52:59 ajc

94 (actual encoding is not implemented yet)
96 Revision 400.2 2002/09/13 15:54:40 ajc
97 * Reversed the above change because I broke it somehow
99 Revision 400.1 2002/09/11 22:46:59 ajc

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

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

124 * Bugfixes and cosmetic changes to listsub system
126 Revision 323.62 2002/08/23 03:37:19 ajc

130 * 'unsubscribe' command (but not 'confirm unsubscribe')
132 Revision 323.60 2002/08/21 21:58:37 ajc
133 * Completed self-service list subscription via web.

139 Revision 323.58 2002/08/16 03:51:12 ajc

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

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

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

404 * Brought over the newer string tokenizer from Citadel
405 * Upgraded all the generic string buffers to 4096 bytes, using the Citadel
406 server's convention of #define SIZ 4096
408 Revision 301.8 2001/11/14 03:20:22 ajc
409 * Add some more of the newer config settings to the site config screen
411 Revision 301.7 2001/09/25 03:34:09 ajc

413 and bail out without bothering the Citadel server.
415 Revision 301.6 2001/08/22 16:38:06 ajc
416 * Added the "-c" command line option to generate optional cookies indicating
417 the host name of the server. This makes it easy to put a cluster of WebCit
418 servers behind (for example) an Arrowpoint load balancer.
420 Revision 301.5 2001/08/21 04:02:56 ajc
421 * Added some more meta-tags to (hopefully) prevent the "lame goto" caused by
422 unwanted page caching
424 Revision 301.4 2001/08/13 03:43:24 ajc
427 Revision 301.3 2001/08/13 03:40:01 ajc

439 Revision 300.2 2001/06/28 15:03:49 ajc
440 * Every generated page now includes a meta tag to disable evil "smart tags"
441 (see http://smarttags.manilasites.com/ for more information)
443 Revision 300.1 2001/06/28 02:39:54 ajc
444 * Placated users who whine about privacy policy by adding MESG ROOMACCESS to

448 * Tagged everything as Version 3.00
450 Revision 213.25 2001/06/27 06:22:49 ajc
451 * Updated docs for the 3.00 release
453 Revision 213.24 2001/06/27 06:16:01 ajc

457 Revision 213.23 2001/06/22 17:58:20 ajc
458 * A few performance and tuning cleanups. Increased the size of the socket
459 queue length to 100 for use on big systems. Also, during startup, the
460 initial startup thread now exits after creating the worker threads, instead
461 of becoming a worker thread itself. For some reason Solaris had problems
462 with the latter method.
464 Revision 213.22 2001/06/07 03:16:57 ajc
465 * Brought over an updated mime parser from Citadel

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

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

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

742 Revision 1.101 1999/10/06 02:44:02 ajc
743 * Per Nick's request, removed the key bindings stuff. He knows how to fit
744 it back in when it's fixed. Also added more attempts at cache disabling,
745 but it still doesn't work in the StarOffice browser. I don't know why.
747 Revision 1.100 1999/10/02 03:26:14 ajc
748 * Merged in Nick's bit of JavaScript to handle key commands.
749 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
750 in a text field. Right now you can't even log in.

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

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

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

827 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
828 * Replaced _most_ gotoroom() calls with smart_goto(), a version

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

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

868 * Added HTTP "User-agent:" detection
869 * wildmat.c, braindamage.c: added
870 * Initial value of 'noframes' is now set by the braindamage check
871 * Ran everything through "indent -kr -i8"
872 * roomops.c: in room list, print a in otherwise empty cells
874 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
875 * context_loop.c: warning fix
876 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
878 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
879 * Resolve the name of the connecting host and pass it on to Citadel
881 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
882 * wDumpContent() is now responsible for </BODY></HTML> most of the
883 time (parameter settable) so that the main menu can easily be
884 embedded in every page when running in noframes mode
885 * noframes mode selection is now carried in the cookie
887 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
888 * Made the frames stuff less dependent on the HTML TARGET= directive
889 and more dependent on the HTTP Window-target: directive.
890 * Made the system semi-navigable in noframes mode.
892 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
893 * Brought over the new room listing code and <G>oto heuristics
894 from the main Citadel tree, to pay attention to floor/room ordering
896 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
897 * Modified the back end of mime_parser to use callbacks instead of
898 doing something specific. Now we can use it elsewhere.
900 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

967 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
968 * context_loop.c: Moved "remove session" into its own function.
969 Check for dead webcit child process before each transaction.
970 * Ignore SIGPIPE; this seems to magically make the program bulletproof
971 against broken HTTP connections.

989 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
990 * context_loop.c: After fork(), child process closes the HTTP socket
991 so when the parent process closes it, it actually _does_ close.
992 Otherwise, aIEeeee and possibly other browsers will hang.
993 * Added support for graphics images retrieved from the Citadel server.
994 * Set up login banner graphic and background image graphic

1004 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1005 * Discovered that the HTTP socket problem is related to a socket that
1006 isn't properly lingering on close. Temporarily hacked a sleep(10)
1007 into context_loop.c until it is figured out.
1009 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1010 * Did a little debugging, still trying to figure out why logging in

1013 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
1014 * Makefile.in: updated dependencies

1036 * tcp_sockets.c: getservbyname() doesn't set errno.
1038 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
1039 * webserver.c: warning fix
