2 Revision 504.7 2004/02/19 03:32:38 ajc
3 * Changed the internal version number to 5.05
4 * Completed the frames fix
6 Revision 504.6 2004/02/18 20:08:29 ajc
7 * Fixed the frameset force reload logic. Now it does the whole frameset
8 without displaying an error in the main frame.
10 Revision 504.5 2004/02/18 19:17:51 ajc
11 * Force reload of frameset if someone tries to escape it. Not perfect
12 but it mostly works at this poing.
14 Revision 504.4 2004/02/17 03:37:11 ajc
15 * Indicate to Citadel that we want Server Generated Invitations when
16 calendar events are saved. (No longer the default in Citadel server.)
18 Revision 504.3 2004/02/09 04:49:32 ajc
19 * Prepare for a way to avoid falling out of the main frameset
21 Revision 504.2 2004/02/09 03:37:57 ajc
22 * Changed the thread pool management algorithm. Detecting idle time between
23 socket accepts was not working reliably on all systems, so we now follow
24 the same algorithm as the Citadel server (spawn more threads when number
25 of sessions < number of threads, but keep constrained to pre-defined
26 minimum and maximum thread count)
28 Revision 504.1 2004/02/03 03:09:51 ajc
31 Revision 503.0 2004/01/28 04:31:31 ajc

45 * Clicking "Enter Message" in a room with an Address Book view opens
46 a blank vCard entry screen.
48 Revision 502.0 2003/10/23 03:16:50 ajc
51 Revision 501.2 2003/10/23 03:07:54 ajc
52 * event.c: Found and removed another unquoted multi-line string literal
53 * webcit.h: changed an #ifdef HAVE_ICAL_H
54 to #ifdef WEBCIT_WITH_CALENDAR_SERVICE to avoid false positives
56 Revision 501.1 2003/10/22 01:42:12 ajc
57 * iconbar.c: removed a stray character or two...
59 Revision 501.0 2003/10/21 04:26:37 ajc
62 Revision 500.30 2003/10/21 04:26:27 ajc

65 Revision 500.29 2003/10/17 03:08:28 ajc
66 * Finished prettying up the vCard display
68 Revision 500.28 2003/10/17 02:31:45 ajc
69 * Multi-line string literals are deprecated in GCC 3.1 unless each line
70 is wrapped in quotes. Performed this fix so it'll compile.
71 * setup.c: removed references to unused variable tempfile[]
73 Revision 500.27 2003/10/09 03:17:02 ajc
74 * Started prettying up the vCard display.
76 Revision 500.26 2003/10/08 02:33:49 ajc
77 * Begin work on better handling of vCard display
79 Revision 500.25 2003/09/04 03:41:27 ajc
80 * siteconfig.c: changed some config items to drop-down boxes
82 Revision 500.24 2003/08/27 04:26:54 ajc
83 * Split the site configuration screen up into four different screens,
86 Revision 500.23 2003/08/24 03:31:50 ajc
87 * Finished the setup program
88 * Bumped the internal version number to 5.01
90 Revision 500.22 2003/08/22 00:47:27 ajc
91 * setup is now working, but it still needs a way to detect a running WebCit
93 Revision 500.21 2003/08/22 00:25:40 ajc
94 * Added a skeleton "setup" program to the tree. It does not work yet.
96 Revision 500.20 2003/08/20 03:48:55 ajc
97 * Added iconbar shortcut to Contacts room
98 * Minimum required Citadel is now 6.11
100 Revision 500.19 2003/08/20 03:07:25 ajc
101 * Address book "single card" view now suppresses "reading nn message" and
102 instead shows the letter indices across the top
103 * Clicking on an address in a vCard now connects to WebCit mail instead
104 of a browser mailto: link
106 Revision 500.18 2003/08/19 04:18:43 ajc
107 * Changed things around in the address book view. Made it sorted and
108 more clickable and better looking...
110 Revision 500.17 2003/08/12 18:54:03 error
111 * messages.c: fix off-by-one-error in selector bar
113 Revision 500.16 2003/08/07 22:18:03 ajc
114 * Add the Summary Page to the customizable iconbar
116 Revision 500.15 2003/08/07 03:51:51 ajc
117 * Customizable icon bar as: pictures and text, pictures, text
119 Revision 500.14 2003/08/05 03:52:14 ajc
120 * First working version of the customizable iconbar. It contains a basic
121 set of options and now automatically refreshes when it's customized.
123 Revision 500.13 2003/08/04 03:50:29 ajc
124 * First cut at the customizable iconbar is done. A bunch of generic options
125 are there. Still need to get the actual iconbar to refresh when changes
128 Revision 500.12 2003/08/03 21:02:01 ajc
129 * More work on customizable iconbar
131 Revision 500.11 2003/08/02 05:25:46 ajc

135 * Add config.c_purge_hour to config screen
137 Revision 500.9 2003/07/06 22:06:59 ajc
138 * When converting "anything that looks like a URL" to a real link, first
139 make sure that it isn't already inside a link. This fixes most of the
140 long, ugly URL strings sent by eBay.
141 * Automatically dismantle mailto: links in HTML messages, and convert
142 them to WebCit mail links (clicking on it sends the user to the Mail
143 room and begins composing a new message with the recipient and subject
144 fields pre-populated).
146 Revision 500.8 2003/06/29 20:51:21 ajc
147 * Worked around a rendering bug in Satan's Browser that was causing it
148 to draw the calendar month view much wider than the actual screen wdith
150 Revision 500.7 2003/06/28 04:09:37 error
151 * roomops.c: Backout change to display one less box in the first column in
152 roomlist view, it doesn't seem to work for everyone
154 Revision 500.6 2003/06/28 03:52:51 error
155 * Don't tell browsers not to cache static documents
157 Revision 500.5 2003/06/28 03:35:23 error
158 * roomops.c: Display one less floor in the first column in romlist view
160 Revision 500.4 2003/06/26 03:37:58 ajc
161 * Allow anonymous HTTP requests for /freebusy/user%20name.vcf (or .vfb)
162 This will allow some groupware clients to browse the free/busy times of
163 other users on the system.
165 Revision 500.3 2003/06/21 05:17:21 ajc
166 * Better alignment of system messages
167 * Exterminated display_error() and replaced it with WC->ImportantMessage
168 which is displayed in a bubble on top of whatever page you're on next.
169 * Small cosmetic changes
170 * Fixed some nesting problems in output_headers()
172 Revision 500.2 2003/06/20 03:39:27 ajc
173 * Optimization to floor layout in box view
175 Revision 500.1 2003/06/20 03:04:26 ajc
176 * "Reply" button on messages now handles IGnet recipients correctly
178 Revision 500.0 2003/06/10 04:23:08 ajc
181 Revision 410.50 2003/06/10 04:22:58 ajc
182 * Updated docs and headers for 5.00 release
184 Revision 410.49 2003/06/10 04:05:23 ajc
185 * De-tabled the left side icon bar and reduced one of the graphics, so
186 that all of the rounded corners show up in Satan's Browser.
188 Revision 410.48 2003/06/10 03:47:41 ajc
189 * style.css: added font selection to default <BODY> tag
191 Revision 410.47 2003/06/06 03:26:03 ajc
192 * Satan's Browser insists on putting bloody acres of whitespace to the
193 right of any bulleted list items, making any multi-column table containing
194 a list take more than the entire screen. Removed all such lists so it
195 looks ok. If you are reading this and you are a Microsoft employee, please
196 commit suicide before you break anything else.
198 Revision 410.46 2003/06/06 02:22:07 ajc
199 * Changed the upper left and upper right bounded box corners to a solid
200 blue (#204B78) instead of gradiated, because it was looking funny in
201 256-color mode. It also looked funny in Internet Explorer, but people
202 who use Internet Explorer are contributing to terrorism and really don't
203 deserve Web access in the first place. So I really just fixed this to make
204 it look good in 256-color Netscape.
206 Revision 410.45 2003/06/05 21:37:37 ajc
207 * Cosmetic changes. Attempting to fix b0rken rendering of main menu
208 in b0rken IE browser. Die, Bill, Die.
210 Revision 410.44 2003/06/05 03:52:29 ajc
211 * Buncha cosmetic changes
213 Revision 410.43 2003/06/04 03:41:25 ajc
214 * Change the appearance of rooms with and without new messages in the
215 room list -- now defined using CSS
217 Revision 410.42 2003/06/03 03:57:42 ajc
218 * Tightened up the room banner a bit. Smaller padding, smaller font,
221 Revision 410.41 2003/05/31 21:36:45 ajc
224 Revision 410.40 2003/05/26 21:05:42 ajc
225 * availability.c: brought over ical_ctdl_is_overlap() from Citadel. Used
226 it to complete the free/busy checking for attendee availability.
228 Revision 410.39 2003/05/26 05:44:45 ajc
229 * event.c: fix compiler warning
231 Revision 410.38 2003/05/26 05:39:46 ajc
232 * webcit.h: change minimum required Citadel server to 6.07 due to FREEBUSY
233 bug fixed in Citadel.
235 Revision 410.37 2003/05/26 05:28:13 ajc
236 * serv_func.c: added utility function read_server_text()
237 * availability.c: banged out more of this code -- still not complete
239 Revision 410.36 2003/05/26 03:28:02 ajc
240 * Getting closer to doing the availability check. Created new source
241 module 'availability.c' for this purpose. Stub function is in place.
243 Revision 410.35 2003/05/25 04:25:12 ajc
244 * siteconfig.c: fixed a spelling error
245 * event.c: add a "Check attendee availability" button, and the code to
246 bypass saving the event to the server, do something with it, and then
247 feed the twiddled data structure back to the form display function for
248 further editing. What's still missing is the code to do the actual
251 Revision 410.34 2003/05/24 22:22:35 ajc
252 * Small stylesheet hack to make it work with b0rken IE
254 Revision 410.33 2003/05/24 22:13:08 ajc
255 * Changed the login banner a bit
257 Revision 410.32 2003/05/20 03:25:41 ajc
258 * Separate event invitees with newlines instead of commas.
260 Revision 410.31 2003/05/19 19:55:09 ajc
261 * summary.c: eliminate compiler warnings about unused variables when
262 compiling a WebCit service without calendar support
264 Revision 410.30 2003/05/18 02:05:33 ajc
265 * More conversion of screens to the new look-and-feel.
267 Revision 410.29 2003/05/16 04:11:29 ajc
268 * We don't need no steenking workaround. Problem fixed. MIME parser not
269 broken. Web server was calling it with bad parameters. All fixed now.
270 * Slightly tweaked the look of the tabs in the room edit screen. Still looks
273 Revision 410.28 2003/05/15 04:52:26 ajc
274 * Minor workaround in web forms to handle mime parser problem in uploads
276 Revision 410.27 2003/05/15 03:35:59 ajc
277 * look and feel overhaul -- almost done!
279 Revision 410.26 2003/05/14 03:46:35 ajc
280 * More background cleanup
282 Revision 410.25 2003/05/05 17:19:46 ajc
283 * Cleanups to summary page when running on a non ical enabled system
284 * Use non breaking spaces in summary page box titles
286 Revision 410.24 2003/05/04 04:22:41 ajc
287 * Display body of messages on a white background. I am doing this in order
288 to prepare for making the general background of the screen a darker color.
290 Revision 410.23 2003/05/04 02:54:55 ajc
291 * Summary page now uses our cutesy new rounded window boxes
293 Revision 410.22 2003/05/03 21:28:41 ajc
294 * Added in a slick new box style and put the room lists in it
296 Revision 410.21 2003/05/03 16:57:04 ajc
297 * In the 'folders' and 'portal' views, change the folder delimiter
298 from / to \ to avoid conflict with room names that have slashes
300 Revision 410.20 2003/05/03 16:23:29 ajc
301 * Enforce three columns in portal view of room list
303 Revision 410.19 2003/05/03 04:52:32 ajc
304 * Added an experimental new "portal view" to the room list options
306 Revision 410.18 2003/05/02 03:23:41 ajc
307 * Minor change to room list algorithm
309 Revision 410.17 2003/05/01 15:33:05 ajc
310 * Fixed a potential memory leak in enumeration of MIME parts
312 Revision 410.16 2003/05/01 03:11:35 ajc
313 * When static content is requested, fetch it without trying to connect
316 Revision 410.15 2003/04/30 05:00:00 ajc
317 * Added the ability to compose messages with file attachments uploaded from
320 Revision 410.14 2003/04/27 04:46:02 ajc
321 * Replace LKRN/LKRO in "folders view" room list with a single LKRA that
322 observes the flag designating the presence of new messages. (The "rooms
323 view" uses an LKRN/LKRO pair *per floor* and has the same inefficiency,
324 but that view may get axed soon.)
326 Revision 410.13 2003/04/26 21:57:53 ajc
327 * tcp_sockets.c: when an outgoing socket connection fails, close the socket
328 before returning an error code to avoid a file descriptor leak
330 Revision 410.12 2003/04/19 21:42:36 ajc
331 * Repaired all my b0rken COLOR tags
332 * Replaced most FONT tags with SPAN tags
335 Revision 410.11 2003/04/19 19:58:10 ajc
336 * Lots of great changes from Nick to make the site CSS-enabled.
338 Revision 410.10 2003/04/14 04:04:40 ajc
339 * First cut of CSS-izing WebCit. Probably b0rken.
341 Revision 410.9 2003/04/09 04:02:32 ajc
342 * Remove the defaulthost/defaultport vs. c_host/c_port stuff -- we haven't
343 supported the idea of one WebCit connecting to multiple Citadels for a
344 long time. Now it's just one set of variables, called ctdlhost/ctdlport.
345 * When connecting to Citadel through a Unix domain socket, don't try to make
346 the Java chat applet available.
348 Revision 410.8 2003/03/31 03:32:19 ajc
349 * messages.c: check for 000 terminator while parsing RFC822 headers to
350 prevent getting hung up while displaying certain badly formatted messages.
352 Revision 410.7 2003/03/30 06:13:19 ajc
353 * When reading from the server, do not treat CR as end-of-line because
354 there's probably an LF coming after it. Instead, keep reading to the LF
356 * No not underline links in the icon bars
358 Revision 410.6 2003/03/17 04:17:41 ajc
359 * Call to accept() was being made with an uninitialized variable for the
360 third argument. Changed the second and third argument to NULL and 0 because
361 we don't really need accept() to fill up a buffer full of information that
362 we'll never use. (Thanks to SteveV for reporting the bug and helping to
364 * Removed the mutex wrapper around select() because we don't need it. All
365 idle worker threads now block on select() and one of them will wake up when
366 a connection arrives.
368 Revision 410.5 2003/03/15 20:55:03 ajc
369 * When a requested image is not available on the Citadel server, send a
370 1x1 transparent GIF instead of 404 error.
372 Revision 410.4 2003/03/14 04:21:57 ajc
373 * clone events to be encapsulated before saving, because the original
374 instance may already have a parent, and that makes crashy crashy
376 Revision 410.3 2003/03/13 05:57:17 ajc
377 * More encapsulation. Warning: there are bugs in this!!
379 Revision 410.2 2003/03/13 05:20:23 ajc
380 * Various changes to the calendar service to handle messages containing
381 fully encapsulated VCALENDAR components instead of only unencapsulated
382 VEVENT subcomponents. We have to move in this direction for compatibility
385 Revision 410.1 2003/03/01 22:07:19 ajc
386 * New user registration, as well as existing user re-registration, now
387 uses the vCard editing screen.
388 * Administratively editing users' address book entries now works again,
389 mainly due to a fix in the Citadel server. Now requiring Citadel 6.06
390 in order to enforce this.
392 Revision 410.0 2003/02/19 03:49:33 ajc
395 Revision 400.90 2003/02/19 03:49:17 ajc
396 * latest config.guess and config.sub from www.gnu.org
398 Revision 400.89 2003/02/07 04:44:17 ajc
399 * Replaced sleep() with a function that sleeps using select() in order to
400 avoid potential issues with SIGALRM. Possible fix for weird behavior
401 when running on a Macintosh.
403 Revision 400.88 2003/01/29 22:32:07 ajc
404 * Shuffled some code and comments around; minor cleanup
406 Revision 400.87 2003/01/28 15:37:12 ajc
407 * All functions which read binary data from the server now make use of the
408 read_server_binary() function in tools.c
409 * Binary reads from server now have safety code to prevent infinite loops
410 * All output of MIME objects is now done with http_transmit_thing()
412 Revision 400.86 2003/01/19 06:28:04 ajc
413 * Minimum required Citadel version 6.05
415 Revision 400.85 2003/01/16 04:41:26 ajc
416 * When displaying edit controls for time of day in the calendar, only show
417 minutes that are multiples of 5 ... unless the existing value is not a
418 multiple of 5, in which case we show that too.
420 Revision 400.84 2003/01/15 17:34:04 ajc
421 * event.c: fixed a misspelling
422 * config.guess, config.sub: updated using latest from ftp.gnu.org
424 Revision 400.83 2003/01/14 04:21:27 ajc
425 * Only offer views which make sense for the default view of a room
427 Revision 400.82 2003/01/13 03:34:33 ajc
428 * Get ready for the 4.10 release
430 Revision 400.81 2003/01/12 23:22:53 ajc
431 * configure.in: check for libical v0.24 or newer
433 Revision 400.80 2003/01/07 04:56:17 ajc
434 * Complete the free/busy transparency handling in the form
435 * Default times for new events are now in the correct timezone
437 Revision 400.79 2003/01/06 18:01:35 ajc
438 * Begin handling of TRANSP property to show event times as free or
441 Revision 400.78 2003/01/05 21:02:14 ajc
442 * Summary page: three columns are now all the same width
444 Revision 400.77 2003/01/05 20:56:05 ajc
445 * minor fix for previous checkin
447 Revision 400.76 2003/01/05 20:51:01 ajc
448 * Display PARTSTAT for attendees
450 Revision 400.75 2003/01/05 05:01:00 ajc
451 * Add "today's calendar events" to the summary page.
453 Revision 400.74 2003/01/05 04:27:28 ajc
454 * Add "Tasks" to the summary page
456 Revision 400.73 2002/12/28 05:44:09 ajc
457 * ical_dezonify.c: brought over new version from the Citadel source (again)
459 Revision 400.72 2002/12/28 05:12:45 ajc
460 * ical_dezonify.c: brought over new version from the Citadel source.
462 Revision 400.71 2002/12/26 04:04:48 ajc
463 * Perform CHEK command when automatically establishing sessions, not just
464 when one is explicitly created. Some stuff is missing otherwise.
466 Revision 400.70 2002/12/25 23:18:06 ajc
467 * Be more strategic about when to call ical_dezonify()
468 (This may be the last set of fixes. I hope so.)
470 Revision 400.69 2002/12/25 21:39:38 ajc
471 * ical_dezonify.c: added.
472 * calendar.c: convert incoming ical messages to UTC
473 (the usual routines will then convert them to local time for display)
475 Revision 400.68 2002/12/25 07:06:00 ajc
476 * Tweaked the code to work with libical 0.24
478 Revision 400.67 2002/12/20 04:50:00 ajc
479 * When saving a calendar event, increment the SEQUENCE property.
481 Revision 400.66 2002/12/18 05:03:39 ajc
482 * In the calendar code, changed all "struct tm *" to "struct tm" and changed
483 all "tm = localtime(foo)" to "memcpy(&tm, localtime(foo), sizeof(struct tm))"
484 Because the libc-allocated buffer was getting clobbered.
485 * This fixes the problem fleeb reported with Feb 1 events making it go nuts.
487 Revision 400.65 2002/12/17 05:01:39 ajc
488 * Prettied up the calendar day view layout
489 * Hour/minute editing fields now use am/pm hours and 2-digit minutes
491 Revision 400.64 2002/12/16 04:43:30 ajc
492 * Correctly handle local time zone when figuring out which day and time to
493 display events on calendar month/day views. This also seems to have
494 fixed the bug that was causing events to sometimes get lost when saved.
496 Revision 400.63 2002/12/15 05:50:59 ajc
497 * Form editing of date/time fields now assumes that the icaltimetype being
498 manipulated is in UTC. It converts to/from local time for editing.
500 Revision 400.62 2002/12/10 23:25:47 ajc
501 * Display attendees in message view of calendar objects
503 Revision 400.61 2002/12/07 22:12:59 ajc
504 * Handle incoming RSVP's for meetings. (Note: this will not actually work
505 until I implement the Citadel server function which it calls.)
507 Revision 400.60 2002/11/30 21:34:51 ajc
508 * Submit organizer in a hidden field, in case the server needs it
510 Revision 400.59 2002/11/30 04:46:46 ajc
511 * First cut at adding/removing attendees to an event
512 (Actual invitations should be sent by the Citadel server)
514 Revision 400.58 2002/11/29 23:56:19 ajc
515 * Completed "me as organizer" -- the user's own e-mail address is inserted
516 as the organizer of new events. Detect when the user is the organizer and
517 enable/disable the attendees box accordingly.
519 Revision 400.57 2002/11/29 16:38:37 ajc
520 * Started some "me as organizer" stuff. (BROKEN BUILD ... I'll fix soon.)
522 Revision 400.56 2002/11/28 06:03:24 ajc
523 * Issue an ISME command when editing an event, to determine whether the user
524 viewing the event is the organizer. (Will use this later to allow/disallow
525 sending out invitations.)
527 Revision 400.55 2002/11/26 05:01:04 ajc
528 * Began handling attendee fields
530 Revision 400.54 2002/11/16 23:40:11 ajc
533 Revision 400.53 2002/11/16 23:15:02 ajc
534 * Make the "all day event" shadebox smaller (month view) - no border.
535 * Fixed bug that caused any events following an all day event to also appear
538 Revision 400.52 2002/11/16 05:40:54 ajc
539 * When adding new events to the calendar, default to the month [and day]
540 currently being viewed.
541 * Hotlink each hour of the day view to an add-new-event for that day/hour.
543 Revision 400.51 2002/11/15 05:05:47 ajc
544 * Put in back/forward (yesterday/tomorrow) links in calendar day view
546 Revision 400.50 2002/11/15 04:11:46 ajc
547 * Added even more nifty JavaScript to cause the hour/minute and end date
548 fields of a calendar event form to render as disabled when the "all day
549 event" box is checked -- not just when the user checks the box, but also
550 when the box begins its life already checked.
552 Revision 400.49 2002/11/14 04:59:40 ajc
553 * Correctly serialize and save all day events using date instead of date/time
555 Revision 400.48 2002/11/13 04:49:23 ajc
556 * "All day event" shows as a single checkbox, instead of one for the start
557 time and one for the end time. Added nifty JavaScript to zero and shade
558 the hour/minute and all end time fields when all-day-event is checked.
560 Revision 400.47 2002/11/12 05:57:27 ajc
561 * Display a nicer looking screen when replying to calendar invitations
562 * When displaying day view, don't show all day events twice
563 * Day or month view: denote all day events by displaying them inside
566 Revision 400.46 2002/11/12 03:26:39 ajc
567 * Tell the user about broken Citadel server connections instead of
568 simply printing "Goodbye"
570 Revision 400.45 2002/10/23 04:11:38 ajc
571 * Detect when a meeting invitation is actually an update for an existing UID
572 and tell the user so.
574 Revision 400.44 2002/10/21 20:16:38 ajc
575 * Display conflicts nicely
577 Revision 400.43 2002/10/21 18:29:14 ajc
578 * Ask server to hunt for conflicts when displaying a meeting invitation
580 Revision 400.42 2002/10/19 21:28:32 ajc

604 Revision 400.35 2002/10/07 23:03:38 ajc
605 * messages.c: don't display room name field when it's blank
607 Revision 400.34 2002/10/07 04:10:37 ajc
608 * When displaying meeting invitations, only show date/time for VEVENT
609 subcomponents. Date/time for other subcomponents are irrelevant.
610 * Cleaned up HTML display of meeting invitations.
612 Revision 400.33 2002/10/03 03:40:31 ajc
613 * Worked on meeting accept/decline a little bit
615 Revision 400.32 2002/09/30 03:58:35 ajc
616 * Dabbled in handling incoming meeting requests
618 Revision 400.31 2002/09/29 20:15:43 ajc

629 * After saving a VEVENT, return to the correct calendar view and date
631 Revision 400.27 2002/09/27 17:15:44 ajc
632 * Removed the gzip compression stuff due to bugs in Internet Explorer.
634 Revision 400.26 2002/09/27 04:37:21 ajc
635 * New, buggy versions of event editing screens
637 Revision 400.25 2002/09/26 22:00:16 ajc
638 * Fixed buggy month-selection algorithm (January is month 0 in 'struct tm' but
639 month 1 in libical functions)
641 Revision 400.24 2002/09/25 21:57:13 ajc
642 * Keep track of msgnums in the two-pass calendar loop, so we can hotlink to
645 Revision 400.23 2002/09/24 04:12:34 ajc
646 * Rough cut of the two-pass calendar display routines (first pass: go thru
647 messages gathering VEVENT items; second pass: render calendar with data)
649 Revision 400.22 2002/09/23 04:01:33 ajc
650 * Presentation changes to calendar month view
652 Revision 400.21 2002/09/22 05:20:27 ajc
653 * Began implementing month view
655 Revision 400.20 2002/09/21 04:38:05 ajc
656 * Added utility functions for displaying vcalendar timestamps in web forms
657 and translating form data back to timestamps.
658 * Completed the "edit task" and "add new task" screens.
660 Revision 400.19 2002/09/20 20:28:08 ajc
661 * Smooth transition between "list tasks" & "edit task" screens
663 Revision 400.18 2002/09/20 03:54:44 ajc
664 * Display the "Tasks" view as a bulleted list with each task clickable
665 * Clicking brings up an (unfinished) "edit task" screen
667 Revision 400.17 2002/09/18 21:44:02 ajc
668 * display VTODO parameters
670 Revision 400.16 2002/09/17 04:21:00 ajc
671 * Handler chains for VCALENDAR and VTODO types
673 Revision 400.15 2002/09/17 03:37:10 ajc
674 * Implemented a 'display handler' infrastructure for various groupware types
676 Revision 400.14 2002/09/16 03:35:12 ajc
677 * Just a bunch of glue code to iterate through the various types of ical
678 objects we could encounter
680 Revision 400.13 2002/09/15 04:05:41 ajc
681 * Process calendar object subcomponents
683 Revision 400.12 2002/09/15 03:40:13 ajc
685 * When a text/calendar MIME type is discovered in a message, send it to
686 the (currently skeleton) parser in calendar.c
687 * calendar.c: skeleton parser for calendar objects which currently just
688 creates an icalcomponent object and frees it.
690 Revision 400.11 2002/09/15 03:16:24 ajc
691 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
692 function namespace in libical
694 Revision 400.10 2002/09/15 02:50:55 ajc
695 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
697 Revision 400.9 2002/09/14 21:33:31 ajc
698 * Backed out compression of inlines -- not all browsers appear to handle it
700 Revision 400.8 2002/09/14 20:20:29 ajc
701 * Attempting to push more stuff through compression. I've introduced some
702 sort of deadlock bug that I can't seem to find yet...
704 Revision 400.7 2002/09/14 20:00:22 ajc
705 * Compress output_image() graphics
707 Revision 400.6 2002/09/14 16:26:35 ajc
708 * output_image() now reads the entire image from Citadel into a buffer before
709 sending it to the browser (for performance reasons, and so it can compress)
711 Revision 400.5 2002/09/14 04:52:59 ajc
712 * Look for the "libical" calendaring library and link it in if present...
714 Revision 400.4 2002/09/14 04:02:36 ajc
715 * Finished gzip compression of dynamic pages (when browser supports it)
717 Revision 400.3 2002/09/13 20:40:53 ajc
718 * Detect when the client browser is capable of gzip encoding
719 (actual encoding is not implemented yet)
721 Revision 400.2 2002/09/13 15:54:40 ajc
722 * Reversed the above change because I broke it somehow
724 Revision 400.1 2002/09/11 22:46:59 ajc
725 * Started adding in compression and calendaring library detects (not finished)
727 Revision 400.0 2002/09/09 03:56:11 ajc

732 --> Open links in new window (as with text msgs)
733 --> Convert loose URL's to hot links (as with text msgs)
735 Revision 323.67 2002/09/06 03:59:11 ajc
736 * Added an "About this server" panel to the Summary page.
737 (Useless fluff, but better than an empty column.)
739 Revision 323.66 2002/08/26 02:57:06 ajc
740 * Rooms listed on the summary page are now clickable-gotoable
742 Revision 323.65 2002/08/26 01:24:09 ajc
743 * Added a "summary" page (rather sparse for now)
745 Revision 323.64 2002/08/24 15:30:48 ajc
746 * GET instead of POST for listsub. Also add a 'Back...' link.
748 Revision 323.63 2002/08/24 05:59:24 ajc
749 * Bugfixes and cosmetic changes to listsub system
751 Revision 323.62 2002/08/23 03:37:19 ajc
752 * Finished all of the subscribe/unsubscribe/confirm stuff! (I think)
754 Revision 323.61 2002/08/22 03:55:47 ajc
755 * 'unsubscribe' command (but not 'confirm unsubscribe')
757 Revision 323.60 2002/08/21 21:58:37 ajc
758 * Completed self-service list subscription via web.
759 (Still need to implement unsubscribe.)

764 Revision 323.58 2002/08/16 03:51:12 ajc
765 * I think I've finally nailed the 'no session' pages now...
767 Revision 323.57 2002/08/15 03:49:47 ajc
768 * Fleshed out the list subscription page a bit
770 Revision 323.56 2002/08/13 19:55:12 ajc
771 * Keep track of the HTTP "Host:" header being sent by the browser.
772 (We're going to need this in the near future)

792 Revision 323.49 2002/07/23 04:43:58 ajc
793 * Updated message reading to use the new MSG4 command, so we can do output
794 of various types of richtext (mainly HTML).
796 Revision 323.48 2002/07/16 03:37:24 ajc
797 * Small change to above
799 Revision 323.47 2002/07/16 03:23:37 ajc

802 Revision 323.46 2002/07/13 04:39:59 ajc
803 * Handle multipart/alternative in a nicer way, giving us the opportunity to
804 output HTML instead of converting to text/plain and back. (Not finished.)
806 Revision 323.45 2002/07/11 03:17:03 ajc
807 * hacks to text_to_server() to transmit messages as HTML
809 Revision 323.44 2002/07/09 04:21:12 ajc
812 Revision 323.43 2002/07/06 03:10:26 ajc

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

825 Revision 323.40 2002/06/16 21:49:02 ajc

975 Revision 320.2 2001/12/26 05:24:11 ajc
976 * Reverted all of the navbar and iconbar functions back to plain, ordinary

1041 * Added the "-c" command line option to generate optional cookies indicating

1084 queue length to 100 for use on big systems. Also, during startup, the
1085 initial startup thread now exits after creating the worker threads, instead
1086 of becoming a worker thread itself. For some reason Solaris had problems
1087 with the latter method.

1220 Revision 211.19 2000/05/18 02:33:39 ajc

1238 crashing every session, every time. (?)
1239 * End the session after displaying robots.txt or nocookies.html, to prevent
1240 big session logjams when either of these conditions are met
1242 Revision 211.14 2000/04/15 15:43:46 nbryant
1243 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

1369 it back in when it's fixed. Also added more attempts at cache disabling,
1370 but it still doesn't work in the StarOffice browser. I don't know why.
1372 Revision 1.100 1999/10/02 03:26:14 ajc
1373 * Merged in Nick's bit of JavaScript to handle key commands.
1374 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is

1387 Mon Jul 12 23:30:24 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1388 * webcit.c: exit Webcit sessions semi-gracefully when the connection

1390 * messages.c: don't auto-link URL's in messages if it would cause
1393 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1394 * Recompiled the Java chat applet using a genuine JDK 1.0.2

1405 Wed Jun 23 21:43:30 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1406 * webcit.c: added "back, top, next" buttons to bottom of each page

1429 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1431 among other places, IE 5. Die, Bill, Die.
1433 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1434 * Fixed the behavior of the "forget room" routine, to properly handle
1435 the transition back to the Lobby after it's all done.
1436 * Added ExpressMessageCat() to allow code to send the user messages
1437 along with incoming express messages
1438 * WebCit now sends the name of the end user's browser as the client
1439 name in a Citadel IDEN command rather than its own name.
1441 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1448 Fri May 14 23:37:02 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1449 * Initial entry to _BASEROOM_ at login now done as a Skip instead
1450 of a Goto, in order to prevent it from first marking all msgs old.
1452 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1453 * Replaced _most_ gotoroom() calls with smart_goto(), a version

1462 * webserver.c: took my name off the copyright notice (it's a group
1465 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1466 * Reworked a lot of the structure, made more HTML "embeddable"
1467 * Changed the noframes mode to display "fake" frames using tables
1469 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nick@ulster.net>
1470 Changed some output formatting (mainly <FONT> tags).
1471 Changed who.c to use urlescputs() rather than escputs()
1472 in urls so GOTOs and User Profiles work when the string has a
1475 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1476 http://www.webreference.com/dhtml/column18/menuFrLoad.html
1477 How to cause "onLoad=" to cause a sibling frame to refresh without
1478 having to use the nonportable HTTP "Window-Target:" directive. Began
1479 implementation of this; it should allow portable NS/IE compatibility.
1481 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1482 * Implemented "access level required to create rooms"
1484 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1485 * webcit.c: modified getz() to *exit* the program when fgets()
1486 returns an error. This is actually the desired behavior; it would
1487 otherwise busy-loop forever on a broken pipe.
1489 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1490 * webcit.c: added to getz() the ability to return an error code;
1491 implemented this in the main loop, hopefully fixing problems
1492 * Added "braindamage" file (frames/JS browser compatibility list)
1493 * Added HTTP "User-agent:" detection
1494 * wildmat.c, braindamage.c: added
1495 * Initial value of 'noframes' is now set by the braindamage check
1496 * Ran everything through "indent -kr -i8"
1497 * roomops.c: in room list, print a in otherwise empty cells
1499 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
1500 * context_loop.c: warning fix
1501 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
1503 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1504 * Resolve the name of the connecting host and pass it on to Citadel
1506 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1507 * wDumpContent() is now responsible for </BODY></HTML> most of the
1508 time (parameter settable) so that the main menu can easily be
1509 embedded in every page when running in noframes mode
1510 * noframes mode selection is now carried in the cookie
1512 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1513 * Made the frames stuff less dependent on the HTML TARGET= directive
1514 and more dependent on the HTTP Window-target: directive.
1515 * Made the system semi-navigable in noframes mode.
1517 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1518 * Brought over the new room listing code and <G>oto heuristics
1519 from the main Citadel tree, to pay attention to floor/room ordering
1521 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1522 * Modified the back end of mime_parser to use callbacks instead of
1523 doing something specific. Now we can use it elsewhere.
1525 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1526 * Fixed the bugs in "Site-wide configuration"
1527 * Added a "generic server commands" screen
1529 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1530 * Reduced the multiple cookies down to one cookie combining all data.
1532 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1533 * Removed wc_host and wc_port cookies.
1534 * Added an "edit your session" screen to change your wholisting.
1536 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1537 * Added "enter registration"
1538 * Set up automatic trigger of Enter Registration when the server
1540 * Established that a one-to-one WebCit/Citadel correspondence will
1541 be required. No big deal due to shared code segments.
1542 * Added "change password"
1543 * Added networking configuration screens. These still need testing.
1544 * Added a "kill session" link to each line of the wholist when
1545 logged in as an aide, and the screens to perform this operation.
1547 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1557 * Wrote mime_parser.c for handling of image uploads. This will also
1558 be used in future Citadel MIME projects.
1560 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1569 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1570 * Changed the "auto read new" functionality from a meta refresh tag
1571 to an "onload" directive (the former was causing graphics problems)
1572 * Added "create room"
1575 Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1586 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1587 * Replace "Citadel/UX" in menu bar with the Citadel/UX logo
1589 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>

1592 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1593 * context_loop.c: Moved "remove session" into its own function.
1594 Check for dead webcit child process before each transaction.
1595 * Ignore SIGPIPE; this seems to magically make the program bulletproof
1596 against broken HTTP connections.
1597 * Added a housekeeping thread to periodically remove dead sessions
1598 and kill idle sessions.
1599 * messages.c: added "delete message" functionality

1614 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1615 * context_loop.c: After fork(), child process closes the HTTP socket
1616 so when the parent process closes it, it actually _does_ close.
1617 Otherwise, aIEeeee and possibly other browsers will hang.
1618 * Added support for graphics images retrieved from the Citadel server.
1619 * Set up login banner graphic and background image graphic
1621 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

1624 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1625 * Smoothed out some of the login/logout code. Failed authentication
1626 now works the way it should.
1627 * Added support for new user login (still need to handle registration).
1629 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1630 * Discovered that the HTTP socket problem is related to a socket that
1631 isn't properly lingering on close. Temporarily hacked a sleep(10)
1632 into context_loop.c until it is figured out.
1634 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1635 * Did a little debugging, still trying to figure out why logging in
1636 displays "Connection reset by peer" error. It used to work...
1638 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
1639 * Makefile.in: updated dependencies
1641 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1661 * tcp_sockets.c: getservbyname() doesn't set errno.
1663 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
1664 * webserver.c: warning fix
