2 Revision 505.11 2004/03/03 05:21:36 ajc
3 * Made the chat screen totally kick-ass sweet. The flickering reload
4 i-frame is now tiny and hidden, and it *appends* new chat data to
5 the viewable window using JavaScript. No flickering + scrollback!
6 * Added a help button to the chat screen.
8 Revision 505.10 2004/02/29 22:52:15 ajc
9 * Close and clear (set to -1) server socket handle when socket errors are

18 Revision 505.7 2004/02/26 04:08:56 ajc
19 * Fixed a problem that made WebCit go to the "no cookies" screen instead
21 * Ford's latest stupid room has a name with more than 64 characters, and
22 we still had a 64-byte room name in the march_list struct. ooooops...
24 Revision 505.6 2004/02/26 03:07:26 ajc
25 * Put the /favicon.ico --> /static/favicon.ico hack back in. Why not?

28 * Allow "/do_logout" as a no-frames page
30 Revision 505.4 2004/02/25 23:00:21 ajc
31 * Changed the favicon support to LINK tags in the HEAD of static stuff,
32 to make life easier. (Thanks to prosthetik for this)
34 Revision 505.3 2004/02/25 15:20:11 ajc
35 * Support for favicon.ico in the static/ directory
37 Revision 505.2 2004/02/24 04:06:42 ajc
38 * Changed the colors slightly in chat screen
40 Revision 505.1 2004/02/20 06:07:06 ajc
41 * Replaced the Java chat with a new system based on IFRAME's and JavaScript
43 Revision 505.0 2004/02/19 03:32:50 ajc
46 Revision 504.7 2004/02/19 03:32:38 ajc

48 * Completed the frames fix
50 Revision 504.6 2004/02/18 20:08:29 ajc

52 without displaying an error in the main frame.
54 Revision 504.5 2004/02/18 19:17:51 ajc
55 * Force reload of frameset if someone tries to escape it. Not perfect
56 but it mostly works at this poing.
58 Revision 504.4 2004/02/17 03:37:11 ajc
59 * Indicate to Citadel that we want Server Generated Invitations when
60 calendar events are saved. (No longer the default in Citadel server.)
62 Revision 504.3 2004/02/09 04:49:32 ajc
63 * Prepare for a way to avoid falling out of the main frameset
65 Revision 504.2 2004/02/09 03:37:57 ajc
66 * Changed the thread pool management algorithm. Detecting idle time between
67 socket accepts was not working reliably on all systems, so we now follow
68 the same algorithm as the Citadel server (spawn more threads when number
69 of sessions < number of threads, but keep constrained to pre-defined
70 minimum and maximum thread count)
72 Revision 504.1 2004/02/03 03:09:51 ajc
75 Revision 503.0 2004/01/28 04:31:31 ajc

89 * Clicking "Enter Message" in a room with an Address Book view opens
90 a blank vCard entry screen.
92 Revision 502.0 2003/10/23 03:16:50 ajc
95 Revision 501.2 2003/10/23 03:07:54 ajc

100 Revision 501.1 2003/10/22 01:42:12 ajc
101 * iconbar.c: removed a stray character or two...
103 Revision 501.0 2003/10/21 04:26:37 ajc

113 * Multi-line string literals are deprecated in GCC 3.1 unless each line
114 is wrapped in quotes. Performed this fix so it'll compile.
115 * setup.c: removed references to unused variable tempfile[]
117 Revision 500.27 2003/10/09 03:17:02 ajc
118 * Started prettying up the vCard display.
120 Revision 500.26 2003/10/08 02:33:49 ajc
121 * Begin work on better handling of vCard display
123 Revision 500.25 2003/09/04 03:41:27 ajc
124 * siteconfig.c: changed some config items to drop-down boxes
126 Revision 500.24 2003/08/27 04:26:54 ajc
127 * Split the site configuration screen up into four different screens,
128 and added a meta-menu
130 Revision 500.23 2003/08/24 03:31:50 ajc
131 * Finished the setup program
132 * Bumped the internal version number to 5.01
134 Revision 500.22 2003/08/22 00:47:27 ajc
135 * setup is now working, but it still needs a way to detect a running WebCit
137 Revision 500.21 2003/08/22 00:25:40 ajc
138 * Added a skeleton "setup" program to the tree. It does not work yet.
140 Revision 500.20 2003/08/20 03:48:55 ajc
141 * Added iconbar shortcut to Contacts room
142 * Minimum required Citadel is now 6.11
144 Revision 500.19 2003/08/20 03:07:25 ajc

146 instead shows the letter indices across the top
147 * Clicking on an address in a vCard now connects to WebCit mail instead
148 of a browser mailto: link
150 Revision 500.18 2003/08/19 04:18:43 ajc
151 * Changed things around in the address book view. Made it sorted and
152 more clickable and better looking...
154 Revision 500.17 2003/08/12 18:54:03 error
155 * messages.c: fix off-by-one-error in selector bar
157 Revision 500.16 2003/08/07 22:18:03 ajc

163 Revision 500.14 2003/08/05 03:52:14 ajc
164 * First working version of the customizable iconbar. It contains a basic
165 set of options and now automatically refreshes when it's customized.
167 Revision 500.13 2003/08/04 03:50:29 ajc
168 * First cut at the customizable iconbar is done. A bunch of generic options
169 are there. Still need to get the actual iconbar to refresh when changes
172 Revision 500.12 2003/08/03 21:02:01 ajc
173 * More work on customizable iconbar
175 Revision 500.11 2003/08/02 05:25:46 ajc

179 * Add config.c_purge_hour to config screen
181 Revision 500.9 2003/07/06 22:06:59 ajc
182 * When converting "anything that looks like a URL" to a real link, first
183 make sure that it isn't already inside a link. This fixes most of the
184 long, ugly URL strings sent by eBay.
185 * Automatically dismantle mailto: links in HTML messages, and convert
186 them to WebCit mail links (clicking on it sends the user to the Mail
187 room and begins composing a new message with the recipient and subject
188 fields pre-populated).
190 Revision 500.8 2003/06/29 20:51:21 ajc
191 * Worked around a rendering bug in Satan's Browser that was causing it
192 to draw the calendar month view much wider than the actual screen wdith
194 Revision 500.7 2003/06/28 04:09:37 error
195 * roomops.c: Backout change to display one less box in the first column in
196 roomlist view, it doesn't seem to work for everyone
198 Revision 500.6 2003/06/28 03:52:51 error
199 * Don't tell browsers not to cache static documents
201 Revision 500.5 2003/06/28 03:35:23 error
202 * roomops.c: Display one less floor in the first column in romlist view
204 Revision 500.4 2003/06/26 03:37:58 ajc
205 * Allow anonymous HTTP requests for /freebusy/user%20name.vcf (or .vfb)
206 This will allow some groupware clients to browse the free/busy times of
207 other users on the system.
209 Revision 500.3 2003/06/21 05:17:21 ajc
210 * Better alignment of system messages
211 * Exterminated display_error() and replaced it with WC->ImportantMessage
212 which is displayed in a bubble on top of whatever page you're on next.
213 * Small cosmetic changes
214 * Fixed some nesting problems in output_headers()
216 Revision 500.2 2003/06/20 03:39:27 ajc
217 * Optimization to floor layout in box view
219 Revision 500.1 2003/06/20 03:04:26 ajc
220 * "Reply" button on messages now handles IGnet recipients correctly
222 Revision 500.0 2003/06/10 04:23:08 ajc
225 Revision 410.50 2003/06/10 04:22:58 ajc
226 * Updated docs and headers for 5.00 release
228 Revision 410.49 2003/06/10 04:05:23 ajc
229 * De-tabled the left side icon bar and reduced one of the graphics, so
230 that all of the rounded corners show up in Satan's Browser.
232 Revision 410.48 2003/06/10 03:47:41 ajc
233 * style.css: added font selection to default <BODY> tag
235 Revision 410.47 2003/06/06 03:26:03 ajc
236 * Satan's Browser insists on putting bloody acres of whitespace to the
237 right of any bulleted list items, making any multi-column table containing
238 a list take more than the entire screen. Removed all such lists so it
239 looks ok. If you are reading this and you are a Microsoft employee, please
240 commit suicide before you break anything else.
242 Revision 410.46 2003/06/06 02:22:07 ajc
243 * Changed the upper left and upper right bounded box corners to a solid
244 blue (#204B78) instead of gradiated, because it was looking funny in
245 256-color mode. It also looked funny in Internet Explorer, but people
246 who use Internet Explorer are contributing to terrorism and really don't
247 deserve Web access in the first place. So I really just fixed this to make
248 it look good in 256-color Netscape.
250 Revision 410.45 2003/06/05 21:37:37 ajc
251 * Cosmetic changes. Attempting to fix b0rken rendering of main menu
252 in b0rken IE browser. Die, Bill, Die.
254 Revision 410.44 2003/06/05 03:52:29 ajc
255 * Buncha cosmetic changes
257 Revision 410.43 2003/06/04 03:41:25 ajc
258 * Change the appearance of rooms with and without new messages in the
259 room list -- now defined using CSS
261 Revision 410.42 2003/06/03 03:57:42 ajc
262 * Tightened up the room banner a bit. Smaller padding, smaller font,
265 Revision 410.41 2003/05/31 21:36:45 ajc
268 Revision 410.40 2003/05/26 21:05:42 ajc
269 * availability.c: brought over ical_ctdl_is_overlap() from Citadel. Used
270 it to complete the free/busy checking for attendee availability.
272 Revision 410.39 2003/05/26 05:44:45 ajc
273 * event.c: fix compiler warning
275 Revision 410.38 2003/05/26 05:39:46 ajc

279 Revision 410.37 2003/05/26 05:28:13 ajc
280 * serv_func.c: added utility function read_server_text()
281 * availability.c: banged out more of this code -- still not complete
283 Revision 410.36 2003/05/26 03:28:02 ajc
284 * Getting closer to doing the availability check. Created new source
285 module 'availability.c' for this purpose. Stub function is in place.
287 Revision 410.35 2003/05/25 04:25:12 ajc
288 * siteconfig.c: fixed a spelling error
289 * event.c: add a "Check attendee availability" button, and the code to
290 bypass saving the event to the server, do something with it, and then
291 feed the twiddled data structure back to the form display function for
292 further editing. What's still missing is the code to do the actual
295 Revision 410.34 2003/05/24 22:22:35 ajc
296 * Small stylesheet hack to make it work with b0rken IE
298 Revision 410.33 2003/05/24 22:13:08 ajc
299 * Changed the login banner a bit
301 Revision 410.32 2003/05/20 03:25:41 ajc
302 * Separate event invitees with newlines instead of commas.
304 Revision 410.31 2003/05/19 19:55:09 ajc
305 * summary.c: eliminate compiler warnings about unused variables when
306 compiling a WebCit service without calendar support
308 Revision 410.30 2003/05/18 02:05:33 ajc
309 * More conversion of screens to the new look-and-feel.
311 Revision 410.29 2003/05/16 04:11:29 ajc
312 * We don't need no steenking workaround. Problem fixed. MIME parser not
313 broken. Web server was calling it with bad parameters. All fixed now.
314 * Slightly tweaked the look of the tabs in the room edit screen. Still looks
317 Revision 410.28 2003/05/15 04:52:26 ajc
318 * Minor workaround in web forms to handle mime parser problem in uploads
320 Revision 410.27 2003/05/15 03:35:59 ajc
321 * look and feel overhaul -- almost done!
323 Revision 410.26 2003/05/14 03:46:35 ajc
324 * More background cleanup
326 Revision 410.25 2003/05/05 17:19:46 ajc
327 * Cleanups to summary page when running on a non ical enabled system
328 * Use non breaking spaces in summary page box titles
330 Revision 410.24 2003/05/04 04:22:41 ajc
331 * Display body of messages on a white background. I am doing this in order
332 to prepare for making the general background of the screen a darker color.
334 Revision 410.23 2003/05/04 02:54:55 ajc
335 * Summary page now uses our cutesy new rounded window boxes
337 Revision 410.22 2003/05/03 21:28:41 ajc
338 * Added in a slick new box style and put the room lists in it
340 Revision 410.21 2003/05/03 16:57:04 ajc
341 * In the 'folders' and 'portal' views, change the folder delimiter
342 from / to \ to avoid conflict with room names that have slashes
344 Revision 410.20 2003/05/03 16:23:29 ajc
345 * Enforce three columns in portal view of room list
347 Revision 410.19 2003/05/03 04:52:32 ajc
348 * Added an experimental new "portal view" to the room list options
350 Revision 410.18 2003/05/02 03:23:41 ajc
351 * Minor change to room list algorithm
353 Revision 410.17 2003/05/01 15:33:05 ajc
354 * Fixed a potential memory leak in enumeration of MIME parts
356 Revision 410.16 2003/05/01 03:11:35 ajc
357 * When static content is requested, fetch it without trying to connect
360 Revision 410.15 2003/04/30 05:00:00 ajc
361 * Added the ability to compose messages with file attachments uploaded from
364 Revision 410.14 2003/04/27 04:46:02 ajc
365 * Replace LKRN/LKRO in "folders view" room list with a single LKRA that
366 observes the flag designating the presence of new messages. (The "rooms
367 view" uses an LKRN/LKRO pair *per floor* and has the same inefficiency,
368 but that view may get axed soon.)
370 Revision 410.13 2003/04/26 21:57:53 ajc
371 * tcp_sockets.c: when an outgoing socket connection fails, close the socket
372 before returning an error code to avoid a file descriptor leak
374 Revision 410.12 2003/04/19 21:42:36 ajc
375 * Repaired all my b0rken COLOR tags
376 * Replaced most FONT tags with SPAN tags
379 Revision 410.11 2003/04/19 19:58:10 ajc
380 * Lots of great changes from Nick to make the site CSS-enabled.
382 Revision 410.10 2003/04/14 04:04:40 ajc
383 * First cut of CSS-izing WebCit. Probably b0rken.
385 Revision 410.9 2003/04/09 04:02:32 ajc
386 * Remove the defaulthost/defaultport vs. c_host/c_port stuff -- we haven't
387 supported the idea of one WebCit connecting to multiple Citadels for a
388 long time. Now it's just one set of variables, called ctdlhost/ctdlport.
389 * When connecting to Citadel through a Unix domain socket, don't try to make
390 the Java chat applet available.
392 Revision 410.8 2003/03/31 03:32:19 ajc
393 * messages.c: check for 000 terminator while parsing RFC822 headers to
394 prevent getting hung up while displaying certain badly formatted messages.
396 Revision 410.7 2003/03/30 06:13:19 ajc
397 * When reading from the server, do not treat CR as end-of-line because
398 there's probably an LF coming after it. Instead, keep reading to the LF
400 * No not underline links in the icon bars
402 Revision 410.6 2003/03/17 04:17:41 ajc
403 * Call to accept() was being made with an uninitialized variable for the
404 third argument. Changed the second and third argument to NULL and 0 because
405 we don't really need accept() to fill up a buffer full of information that
406 we'll never use. (Thanks to SteveV for reporting the bug and helping to
408 * Removed the mutex wrapper around select() because we don't need it. All
409 idle worker threads now block on select() and one of them will wake up when
410 a connection arrives.
412 Revision 410.5 2003/03/15 20:55:03 ajc
413 * When a requested image is not available on the Citadel server, send a
414 1x1 transparent GIF instead of 404 error.
416 Revision 410.4 2003/03/14 04:21:57 ajc
417 * clone events to be encapsulated before saving, because the original
418 instance may already have a parent, and that makes crashy crashy
420 Revision 410.3 2003/03/13 05:57:17 ajc
421 * More encapsulation. Warning: there are bugs in this!!
423 Revision 410.2 2003/03/13 05:20:23 ajc
424 * Various changes to the calendar service to handle messages containing
425 fully encapsulated VCALENDAR components instead of only unencapsulated
426 VEVENT subcomponents. We have to move in this direction for compatibility
429 Revision 410.1 2003/03/01 22:07:19 ajc
430 * New user registration, as well as existing user re-registration, now
431 uses the vCard editing screen.
432 * Administratively editing users' address book entries now works again,
433 mainly due to a fix in the Citadel server. Now requiring Citadel 6.06
434 in order to enforce this.
436 Revision 410.0 2003/02/19 03:49:33 ajc
439 Revision 400.90 2003/02/19 03:49:17 ajc
440 * latest config.guess and config.sub from www.gnu.org
442 Revision 400.89 2003/02/07 04:44:17 ajc
443 * Replaced sleep() with a function that sleeps using select() in order to
444 avoid potential issues with SIGALRM. Possible fix for weird behavior
445 when running on a Macintosh.
447 Revision 400.88 2003/01/29 22:32:07 ajc
448 * Shuffled some code and comments around; minor cleanup
450 Revision 400.87 2003/01/28 15:37:12 ajc
451 * All functions which read binary data from the server now make use of the
452 read_server_binary() function in tools.c
453 * Binary reads from server now have safety code to prevent infinite loops
454 * All output of MIME objects is now done with http_transmit_thing()
456 Revision 400.86 2003/01/19 06:28:04 ajc
457 * Minimum required Citadel version 6.05
459 Revision 400.85 2003/01/16 04:41:26 ajc
460 * When displaying edit controls for time of day in the calendar, only show
461 minutes that are multiples of 5 ... unless the existing value is not a
462 multiple of 5, in which case we show that too.
464 Revision 400.84 2003/01/15 17:34:04 ajc

481 Revision 400.79 2003/01/06 18:01:35 ajc
482 * Begin handling of TRANSP property to show event times as free or
485 Revision 400.78 2003/01/05 21:02:14 ajc
486 * Summary page: three columns are now all the same width
488 Revision 400.77 2003/01/05 20:56:05 ajc
489 * minor fix for previous checkin
491 Revision 400.76 2003/01/05 20:51:01 ajc

503 Revision 400.72 2002/12/28 05:12:45 ajc
504 * ical_dezonify.c: brought over new version from the Citadel source.
506 Revision 400.71 2002/12/26 04:04:48 ajc
507 * Perform CHEK command when automatically establishing sessions, not just
508 when one is explicitly created. Some stuff is missing otherwise.
510 Revision 400.70 2002/12/25 23:18:06 ajc
511 * Be more strategic about when to call ical_dezonify()
512 (This may be the last set of fixes. I hope so.)
514 Revision 400.69 2002/12/25 21:39:38 ajc
515 * ical_dezonify.c: added.
516 * calendar.c: convert incoming ical messages to UTC
517 (the usual routines will then convert them to local time for display)
519 Revision 400.68 2002/12/25 07:06:00 ajc
520 * Tweaked the code to work with libical 0.24
522 Revision 400.67 2002/12/20 04:50:00 ajc
523 * When saving a calendar event, increment the SEQUENCE property.
525 Revision 400.66 2002/12/18 05:03:39 ajc
526 * In the calendar code, changed all "struct tm *" to "struct tm" and changed
527 all "tm = localtime(foo)" to "memcpy(&tm, localtime(foo), sizeof(struct tm))"
528 Because the libc-allocated buffer was getting clobbered.
529 * This fixes the problem fleeb reported with Feb 1 events making it go nuts.
531 Revision 400.65 2002/12/17 05:01:39 ajc
532 * Prettied up the calendar day view layout

536 * Correctly handle local time zone when figuring out which day and time to
537 display events on calendar month/day views. This also seems to have
538 fixed the bug that was causing events to sometimes get lost when saved.
540 Revision 400.63 2002/12/15 05:50:59 ajc
541 * Form editing of date/time fields now assumes that the icaltimetype being
542 manipulated is in UTC. It converts to/from local time for editing.
544 Revision 400.62 2002/12/10 23:25:47 ajc
545 * Display attendees in message view of calendar objects
547 Revision 400.61 2002/12/07 22:12:59 ajc
548 * Handle incoming RSVP's for meetings. (Note: this will not actually work
549 until I implement the Citadel server function which it calls.)
551 Revision 400.60 2002/11/30 21:34:51 ajc
552 * Submit organizer in a hidden field, in case the server needs it
554 Revision 400.59 2002/11/30 04:46:46 ajc
555 * First cut at adding/removing attendees to an event
556 (Actual invitations should be sent by the Citadel server)
558 Revision 400.58 2002/11/29 23:56:19 ajc
559 * Completed "me as organizer" -- the user's own e-mail address is inserted
560 as the organizer of new events. Detect when the user is the organizer and
561 enable/disable the attendees box accordingly.
563 Revision 400.57 2002/11/29 16:38:37 ajc
564 * Started some "me as organizer" stuff. (BROKEN BUILD ... I'll fix soon.)
566 Revision 400.56 2002/11/28 06:03:24 ajc
567 * Issue an ISME command when editing an event, to determine whether the user
568 viewing the event is the organizer. (Will use this later to allow/disallow
569 sending out invitations.)
571 Revision 400.55 2002/11/26 05:01:04 ajc
572 * Began handling attendee fields
574 Revision 400.54 2002/11/16 23:40:11 ajc
577 Revision 400.53 2002/11/16 23:15:02 ajc
578 * Make the "all day event" shadebox smaller (month view) - no border.
579 * Fixed bug that caused any events following an all day event to also appear
582 Revision 400.52 2002/11/16 05:40:54 ajc
583 * When adding new events to the calendar, default to the month [and day]
584 currently being viewed.
585 * Hotlink each hour of the day view to an add-new-event for that day/hour.
587 Revision 400.51 2002/11/15 05:05:47 ajc
588 * Put in back/forward (yesterday/tomorrow) links in calendar day view
590 Revision 400.50 2002/11/15 04:11:46 ajc
591 * Added even more nifty JavaScript to cause the hour/minute and end date
592 fields of a calendar event form to render as disabled when the "all day
593 event" box is checked -- not just when the user checks the box, but also
594 when the box begins its life already checked.
596 Revision 400.49 2002/11/14 04:59:40 ajc
597 * Correctly serialize and save all day events using date instead of date/time
599 Revision 400.48 2002/11/13 04:49:23 ajc
600 * "All day event" shows as a single checkbox, instead of one for the start
601 time and one for the end time. Added nifty JavaScript to zero and shade
602 the hour/minute and all end time fields when all-day-event is checked.
604 Revision 400.47 2002/11/12 05:57:27 ajc
605 * Display a nicer looking screen when replying to calendar invitations
606 * When displaying day view, don't show all day events twice
607 * Day or month view: denote all day events by displaying them inside
610 Revision 400.46 2002/11/12 03:26:39 ajc
611 * Tell the user about broken Citadel server connections instead of
612 simply printing "Goodbye"
614 Revision 400.45 2002/10/23 04:11:38 ajc
615 * Detect when a meeting invitation is actually an update for an existing UID
616 and tell the user so.
618 Revision 400.44 2002/10/21 20:16:38 ajc
619 * Display conflicts nicely
621 Revision 400.43 2002/10/21 18:29:14 ajc
622 * Ask server to hunt for conflicts when displaying a meeting invitation
624 Revision 400.42 2002/10/19 21:28:32 ajc
625 * Moved the calendar meeting request reply functionality to the Citadel server

646 * Templatized the <HEAD> section of HTML
648 Revision 400.35 2002/10/07 23:03:38 ajc
649 * messages.c: don't display room name field when it's blank
651 Revision 400.34 2002/10/07 04:10:37 ajc
652 * When displaying meeting invitations, only show date/time for VEVENT
653 subcomponents. Date/time for other subcomponents are irrelevant.
654 * Cleaned up HTML display of meeting invitations.
656 Revision 400.33 2002/10/03 03:40:31 ajc
657 * Worked on meeting accept/decline a little bit
659 Revision 400.32 2002/09/30 03:58:35 ajc

671 Revision 400.28 2002/09/27 18:31:33 ajc
672 * Properly handle VEVENT saves (fixed nasty loopy loopy bug)
673 * After saving a VEVENT, return to the correct calendar view and date
675 Revision 400.27 2002/09/27 17:15:44 ajc
676 * Removed the gzip compression stuff due to bugs in Internet Explorer.
678 Revision 400.26 2002/09/27 04:37:21 ajc
679 * New, buggy versions of event editing screens
681 Revision 400.25 2002/09/26 22:00:16 ajc
682 * Fixed buggy month-selection algorithm (January is month 0 in 'struct tm' but
683 month 1 in libical functions)
685 Revision 400.24 2002/09/25 21:57:13 ajc
686 * Keep track of msgnums in the two-pass calendar loop, so we can hotlink to
689 Revision 400.23 2002/09/24 04:12:34 ajc
690 * Rough cut of the two-pass calendar display routines (first pass: go thru
691 messages gathering VEVENT items; second pass: render calendar with data)
693 Revision 400.22 2002/09/23 04:01:33 ajc
694 * Presentation changes to calendar month view
696 Revision 400.21 2002/09/22 05:20:27 ajc
697 * Began implementing month view
699 Revision 400.20 2002/09/21 04:38:05 ajc
700 * Added utility functions for displaying vcalendar timestamps in web forms
701 and translating form data back to timestamps.
702 * Completed the "edit task" and "add new task" screens.
704 Revision 400.19 2002/09/20 20:28:08 ajc
705 * Smooth transition between "list tasks" & "edit task" screens
707 Revision 400.18 2002/09/20 03:54:44 ajc
708 * Display the "Tasks" view as a bulleted list with each task clickable
709 * Clicking brings up an (unfinished) "edit task" screen
711 Revision 400.17 2002/09/18 21:44:02 ajc
712 * display VTODO parameters
714 Revision 400.16 2002/09/17 04:21:00 ajc
715 * Handler chains for VCALENDAR and VTODO types
717 Revision 400.15 2002/09/17 03:37:10 ajc
718 * Implemented a 'display handler' infrastructure for various groupware types
720 Revision 400.14 2002/09/16 03:35:12 ajc
721 * Just a bunch of glue code to iterate through the various types of ical
722 objects we could encounter
724 Revision 400.13 2002/09/15 04:05:41 ajc
725 * Process calendar object subcomponents
727 Revision 400.12 2002/09/15 03:40:13 ajc
729 * When a text/calendar MIME type is discovered in a message, send it to
730 the (currently skeleton) parser in calendar.c
731 * calendar.c: skeleton parser for calendar objects which currently just
732 creates an icalcomponent object and frees it.
734 Revision 400.11 2002/09/15 03:16:24 ajc
735 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
736 function namespace in libical
738 Revision 400.10 2002/09/15 02:50:55 ajc
739 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
741 Revision 400.9 2002/09/14 21:33:31 ajc
742 * Backed out compression of inlines -- not all browsers appear to handle it
744 Revision 400.8 2002/09/14 20:20:29 ajc
745 * Attempting to push more stuff through compression. I've introduced some
746 sort of deadlock bug that I can't seem to find yet...
748 Revision 400.7 2002/09/14 20:00:22 ajc
749 * Compress output_image() graphics
751 Revision 400.6 2002/09/14 16:26:35 ajc
752 * output_image() now reads the entire image from Citadel into a buffer before
753 sending it to the browser (for performance reasons, and so it can compress)
755 Revision 400.5 2002/09/14 04:52:59 ajc
756 * Look for the "libical" calendaring library and link it in if present...
758 Revision 400.4 2002/09/14 04:02:36 ajc
759 * Finished gzip compression of dynamic pages (when browser supports it)
761 Revision 400.3 2002/09/13 20:40:53 ajc
762 * Detect when the client browser is capable of gzip encoding
763 (actual encoding is not implemented yet)
765 Revision 400.2 2002/09/13 15:54:40 ajc
766 * Reversed the above change because I broke it somehow
768 Revision 400.1 2002/09/11 22:46:59 ajc
769 * Started adding in compression and calendaring library detects (not finished)
771 Revision 400.0 2002/09/09 03:56:11 ajc
772 * This is version 4.00
774 Revision 323.68 2002/09/09 03:51:01 ajc
775 * In the HTML-to-HTML converter:
776 --> Open links in new window (as with text msgs)
777 --> Convert loose URL's to hot links (as with text msgs)
779 Revision 323.67 2002/09/06 03:59:11 ajc
780 * Added an "About this server" panel to the Summary page.
781 (Useless fluff, but better than an empty column.)
783 Revision 323.66 2002/08/26 02:57:06 ajc
784 * Rooms listed on the summary page are now clickable-gotoable
786 Revision 323.65 2002/08/26 01:24:09 ajc
787 * Added a "summary" page (rather sparse for now)
789 Revision 323.64 2002/08/24 15:30:48 ajc
790 * GET instead of POST for listsub. Also add a 'Back...' link.
792 Revision 323.63 2002/08/24 05:59:24 ajc
793 * Bugfixes and cosmetic changes to listsub system
795 Revision 323.62 2002/08/23 03:37:19 ajc
796 * Finished all of the subscribe/unsubscribe/confirm stuff! (I think)
798 Revision 323.61 2002/08/22 03:55:47 ajc
799 * 'unsubscribe' command (but not 'confirm unsubscribe')
801 Revision 323.60 2002/08/21 21:58:37 ajc
802 * Completed self-service list subscription via web.
803 (Still need to implement unsubscribe.)
805 Revision 323.59 2002/08/16 22:06:51 ajc
808 Revision 323.58 2002/08/16 03:51:12 ajc
809 * I think I've finally nailed the 'no session' pages now...
811 Revision 323.57 2002/08/15 03:49:47 ajc
812 * Fleshed out the list subscription page a bit
814 Revision 323.56 2002/08/13 19:55:12 ajc
815 * Keep track of the HTTP "Host:" header being sent by the browser.
816 (We're going to need this in the near future)
818 Revision 323.55 2002/08/05 16:07:30 ajc
819 * Moved "edit floor label pic" to the floor editing screen
821 Revision 323.54 2002/08/05 15:53:00 ajc
822 * Commands to add, change, delete floors
824 Revision 323.53 2002/07/26 03:20:04 ajc
825 * Beautified the folder tabs in "edit room"

830 Revision 323.51 2002/07/24 04:14:23 ajc
831 * Minor code cleanup of last night's changes
833 Revision 323.50 2002/07/23 15:40:54 ajc
834 * Minor cleanup of previous changes
836 Revision 323.49 2002/07/23 04:43:58 ajc
837 * Updated message reading to use the new MSG4 command, so we can do output
838 of various types of richtext (mainly HTML).
840 Revision 323.48 2002/07/16 03:37:24 ajc
841 * Small change to above
843 Revision 323.47 2002/07/16 03:23:37 ajc
844 * Display HTML messages as HTML. (Wow!)
846 Revision 323.46 2002/07/13 04:39:59 ajc
847 * Handle multipart/alternative in a nicer way, giving us the opportunity to
848 output HTML instead of converting to text/plain and back. (Not finished.)
850 Revision 323.45 2002/07/11 03:17:03 ajc
851 * hacks to text_to_server() to transmit messages as HTML
853 Revision 323.44 2002/07/09 04:21:12 ajc
856 Revision 323.43 2002/07/06 03:10:26 ajc

858 Configures a user's preference of where to go after login.
860 Revision 323.42 2002/06/19 22:01:31 ajc
861 * When editing another user's vCard, do a "transient goto" to their config
862 room so you don't automatically gain access to their config room.
863 * When creating a user, go back to the "select user to edit" screen with the
864 new user's account name pre-selected.
866 Revision 323.41 2002/06/17 03:48:44 ajc

869 Revision 323.40 2002/06/16 21:49:02 ajc
870 * Administratively edit other users' vCards. Still needs a couple of lines
871 of glue code to make it work.

883 Revision 323.36 2002/05/22 01:53:23 ajc
884 * Room list or folder list? Give the user a choice. (Has bugs.)
886 Revision 323.35 2002/05/12 15:21:43 error
887 * do_template() now parses a .wml file for WAP clients, and a .html file
890 Revision 323.34 2002/05/11 22:46:19 error
891 * Track whether user-agent is a WAP gateway
893 Revision 323.33 2002/05/11 15:35:07 error
894 * webcit.c: add MIME types for WAP/WML
896 Revision 323.32 2002/05/10 15:29:58 ajc
897 * Hacked the address book view a little bit
899 Revision 323.31 2002/05/09 03:53:56 ajc
900 * Began working on address book view
902 Revision 323.30 2002/05/08 03:38:58 ajc

912 * Finished "folder list" mode (still need to move it to a permanent location)
914 Revision 323.26 2002/05/03 03:55:17 ajc
915 * more folder display stuff
917 Revision 323.25 2002/05/01 22:03:07 ajc

1128 queue length to 100 for use on big systems. Also, during startup, the
1129 initial startup thread now exits after creating the worker threads, instead
1130 of becoming a worker thread itself. For some reason Solaris had problems
1131 with the latter method.

1374 Revision 1.112 1999/12/04 21:56:59 ajc
1375 * Finished the overhaul. Now to tune...
1377 Revision 1.111 1999/12/03 17:59:53 ajc
1378 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
1379 pseudocode so the build is currently broken.
1381 Revision 1.110 1999/12/03 16:37:46 ajc
1382 * Repaired HTTP output for image transfers and static content
1384 Revision 1.109 1999/12/03 05:09:54 ajc
1385 * Rewrote the HTTP engine and application coupling to run in a worker thread
1386 model and to run as a single multithreaded program (eliminated helper
1387 processes and pipes). It currently runs but has many large bugs.
1389 Revision 1.108 1999/12/03 00:18:20 ajc
1390 * Added ".c.o" rule to Makefile
1392 Revision 1.107 1999/11/26 03:32:59 ajc

1409 * Minor bug fix in registration screen
1411 Revision 1.101 1999/10/06 02:44:02 ajc
1412 * Per Nick's request, removed the key bindings stuff. He knows how to fit
1413 it back in when it's fixed. Also added more attempts at cache disabling,
1414 but it still doesn't work in the StarOffice browser. I don't know why.
1416 Revision 1.100 1999/10/02 03:26:14 ajc
1417 * Merged in Nick's bit of JavaScript to handle key commands.
1418 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
1419 in a text field. Right now you can't even log in.
1421 Revision 1.99 1999/09/01 01:06:11 ajc

1424 Revision 1.98 1999/08/14 18:16:10 ajc
1425 * Fixed escputs() and its friends to properly handle ' (single quote) chars
1428 Sun Jul 18 20:17:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1429 * Did neat stuff to the bottom of the page
1431 Mon Jul 12 23:30:24 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1432 * webcit.c: exit Webcit sessions semi-gracefully when the connection
1433 to a Citadel server fails.
1434 * messages.c: don't auto-link URL's in messages if it would cause
1437 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1438 * Recompiled the Java chat applet using a genuine JDK 1.0.2
1439 compiler. This should make more browsers happy.
1441 Wed Jun 30 19:19:59 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1442 * Added support for "robots.txt" telling spiders to go away.

1447 server command" to avoid nested server operations
1449 Wed Jun 23 21:43:30 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1450 * webcit.c: added "back, top, next" buttons to bottom of each page
1451 * menubar.html: replaced "User list" with "Page another user"
1453 Tue Jun 22 14:53:05 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1454 * context_loop.c: rearranged some code to try to eliminate deadlocks
1456 Fri Jun 18 11:55:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1457 * Unknown URL's now display the main menu instead of diagnostics
1458 * Diagnostics are now at <baseurl>/diagnostics
1460 Mon Jun 7 21:59:45 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1461 * Session no longer locks up when an express message is cancelled
1462 * The default Citadel server is now "localhost" instead of uncnsrd
1463 * Added some documentation
1465 Thu Jun 3 12:18:49 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1473 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1474 * Ditched the frames mode completely. It wasn't working properly in,
1475 among other places, IE 5. Die, Bill, Die.
1477 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1478 * Fixed the behavior of the "forget room" routine, to properly handle
1479 the transition back to the Lobby after it's all done.
1480 * Added ExpressMessageCat() to allow code to send the user messages
1481 along with incoming express messages
1482 * WebCit now sends the name of the end user's browser as the client
1483 name in a Citadel IDEN command rather than its own name.
1485 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1486 * Minor code cleanups

1490 * Top-aligned all the cells in the fake frames in non-frames mode
1492 Fri May 14 23:37:02 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1493 * Initial entry to _BASEROOM_ at login now done as a Skip instead
1494 of a Goto, in order to prevent it from first marking all msgs old.
1496 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1497 * Replaced _most_ gotoroom() calls with smart_goto(), a version
1498 which can differentiate the needs of frames and noframes modes
1500 Sat May 8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1501 * webserver.c: added "-t" option to send traces somewhere else
1503 Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1505 requests a non-root page and there is no cookie set
1506 * webserver.c: took my name off the copyright notice (it's a group
1509 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1510 * Reworked a lot of the structure, made more HTML "embeddable"
1511 * Changed the noframes mode to display "fake" frames using tables
1513 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nick@ulster.net>
1514 Changed some output formatting (mainly <FONT> tags).
1515 Changed who.c to use urlescputs() rather than escputs()
1516 in urls so GOTOs and User Profiles work when the string has a
1519 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1520 http://www.webreference.com/dhtml/column18/menuFrLoad.html
1521 How to cause "onLoad=" to cause a sibling frame to refresh without
1522 having to use the nonportable HTTP "Window-Target:" directive. Began
1523 implementation of this; it should allow portable NS/IE compatibility.
1525 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1526 * Implemented "access level required to create rooms"
1528 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1529 * webcit.c: modified getz() to *exit* the program when fgets()
1530 returns an error. This is actually the desired behavior; it would
1531 otherwise busy-loop forever on a broken pipe.
1533 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1534 * webcit.c: added to getz() the ability to return an error code;
1535 implemented this in the main loop, hopefully fixing problems
1536 * Added "braindamage" file (frames/JS browser compatibility list)
1537 * Added HTTP "User-agent:" detection
1538 * wildmat.c, braindamage.c: added
1539 * Initial value of 'noframes' is now set by the braindamage check
1540 * Ran everything through "indent -kr -i8"
1541 * roomops.c: in room list, print a in otherwise empty cells
1543 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
1544 * context_loop.c: warning fix
1545 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
1547 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1548 * Resolve the name of the connecting host and pass it on to Citadel
1550 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1551 * wDumpContent() is now responsible for </BODY></HTML> most of the
1552 time (parameter settable) so that the main menu can easily be
1553 embedded in every page when running in noframes mode
1554 * noframes mode selection is now carried in the cookie
1556 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1557 * Made the frames stuff less dependent on the HTML TARGET= directive
1558 and more dependent on the HTTP Window-target: directive.
1559 * Made the system semi-navigable in noframes mode.
1561 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1562 * Brought over the new room listing code and <G>oto heuristics
1563 from the main Citadel tree, to pay attention to floor/room ordering
1565 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1566 * Modified the back end of mime_parser to use callbacks instead of
1567 doing something specific. Now we can use it elsewhere.
1569 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1570 * Fixed the bugs in "Site-wide configuration"
1571 * Added a "generic server commands" screen
1573 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1574 * Reduced the multiple cookies down to one cookie combining all data.
1576 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1577 * Removed wc_host and wc_port cookies.
1578 * Added an "edit your session" screen to change your wholisting.
1580 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1581 * Added "enter registration"
1582 * Set up automatic trigger of Enter Registration when the server
1584 * Established that a one-to-one WebCit/Citadel correspondence will
1585 be required. No big deal due to shared code segments.
1586 * Added "change password"
1587 * Added networking configuration screens. These still need testing.
1588 * Added a "kill session" link to each line of the wholist when
1589 logged in as an aide, and the screens to perform this operation.
1591 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1592 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
1593 * "Finished" the MIME parser.
1594 * Got image uploads working.

1600 Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1601 * Wrote mime_parser.c for handling of image uploads. This will also
1602 be used in future Citadel MIME projects.
1604 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1605 * Fixed a bug in the room banner display code

1610 * Added "edit room info file"
1613 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1614 * Changed the "auto read new" functionality from a meta refresh tag
1615 to an "onload" directive (the former was causing graphics problems)
1616 * Added "create room"
1619 Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1620 * Got the Zap and List-Zapped commands working

1626 * Changed message headers to display in bigger font, non-boldface
1627 * Added the chat system
1628 * Added goto private rooms
1630 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1631 * Replace "Citadel/UX" in menu bar with the Citadel/UX logo
1633 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
1634 * automatically regenerate Makefile when Makefile.in changes
1636 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1637 * context_loop.c: Moved "remove session" into its own function.
1638 Check for dead webcit child process before each transaction.
1639 * Ignore SIGPIPE; this seems to magically make the program bulletproof
1640 against broken HTTP connections.
1641 * Added a housekeeping thread to periodically remove dead sessions
1642 and kill idle sessions.
1643 * messages.c: added "delete message" functionality
1644 * messages.c: added "move message" functionality
1645 * userlist.c: added. This adds "userlist" and "show user" functions.

1651 Fri Dec 11 21:14:36 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1652 * Brought over message reading and entry functions from old WebCit
1654 1998-12-10 Nathan Bryant <bryant@cs.usm.maine.edu>

1656 * webserver.c: remove commented-out references to SO_LINGER
1658 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1659 * context_loop.c: After fork(), child process closes the HTTP socket
1660 so when the parent process closes it, it actually _does_ close.
1661 Otherwise, aIEeeee and possibly other browsers will hang.
1662 * Added support for graphics images retrieved from the Citadel server.
1663 * Set up login banner graphic and background image graphic
1665 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

1668 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1669 * Smoothed out some of the login/logout code. Failed authentication
1670 now works the way it should.
1671 * Added support for new user login (still need to handle registration).
1673 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1674 * Discovered that the HTTP socket problem is related to a socket that
1675 isn't properly lingering on close. Temporarily hacked a sleep(10)
1676 into context_loop.c until it is figured out.
1678 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1679 * Did a little debugging, still trying to figure out why logging in
1680 displays "Connection reset by peer" error. It used to work...
1682 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
1683 * Makefile.in: updated dependencies
1685 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1686 * Fixed broken interpretation of variables specified in the URL
1687 * added new "action" variable to make main loop simpler
1689 1998-12-06 Nathan Bryant <bryant@cs.usm.maine.edu>

1700 * webserver.c, context_loop.c, webcit.c: add commandline args for host
1702 * converted to autoconf and began port to Digital UNIX
1704 * context_loop.c: moved the monster 64k buffer array off the stack
1705 * tcp_sockets.c: getservbyname() doesn't set errno.
1707 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
1708 * webserver.c: warning fix
