2 Revision 505.2 2004/02/24 04:06:42 ajc
3 * Changed the colors slightly in chat screen
5 Revision 505.1 2004/02/20 06:07:06 ajc
6 * Replaced the Java chat with a new system based on IFRAME's and JavaScript
8 Revision 505.0 2004/02/19 03:32:50 ajc
11 Revision 504.7 2004/02/19 03:32:38 ajc

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

53 Revision 502.1 2003/10/24 02:50:19 ajc
54 * Clicking "Enter Message" in a room with an Address Book view opens
55 a blank vCard entry screen.
57 Revision 502.0 2003/10/23 03:16:50 ajc
60 Revision 501.2 2003/10/23 03:07:54 ajc
61 * event.c: Found and removed another unquoted multi-line string literal
62 * webcit.h: changed an #ifdef HAVE_ICAL_H
63 to #ifdef WEBCIT_WITH_CALENDAR_SERVICE to avoid false positives
65 Revision 501.1 2003/10/22 01:42:12 ajc
66 * iconbar.c: removed a stray character or two...
68 Revision 501.0 2003/10/21 04:26:37 ajc

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

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

611 * Templatized the <HEAD> section of HTML
613 Revision 400.35 2002/10/07 23:03:38 ajc
614 * messages.c: don't display room name field when it's blank
616 Revision 400.34 2002/10/07 04:10:37 ajc
617 * When displaying meeting invitations, only show date/time for VEVENT
618 subcomponents. Date/time for other subcomponents are irrelevant.
619 * Cleaned up HTML display of meeting invitations.
621 Revision 400.33 2002/10/03 03:40:31 ajc
622 * Worked on meeting accept/decline a little bit
624 Revision 400.32 2002/09/30 03:58:35 ajc
625 * Dabbled in handling incoming meeting requests
627 Revision 400.31 2002/09/29 20:15:43 ajc

636 Revision 400.28 2002/09/27 18:31:33 ajc
637 * Properly handle VEVENT saves (fixed nasty loopy loopy bug)
638 * After saving a VEVENT, return to the correct calendar view and date
640 Revision 400.27 2002/09/27 17:15:44 ajc
641 * Removed the gzip compression stuff due to bugs in Internet Explorer.
643 Revision 400.26 2002/09/27 04:37:21 ajc
644 * New, buggy versions of event editing screens
646 Revision 400.25 2002/09/26 22:00:16 ajc
647 * Fixed buggy month-selection algorithm (January is month 0 in 'struct tm' but
648 month 1 in libical functions)
650 Revision 400.24 2002/09/25 21:57:13 ajc
651 * Keep track of msgnums in the two-pass calendar loop, so we can hotlink to
654 Revision 400.23 2002/09/24 04:12:34 ajc
655 * Rough cut of the two-pass calendar display routines (first pass: go thru
656 messages gathering VEVENT items; second pass: render calendar with data)
658 Revision 400.22 2002/09/23 04:01:33 ajc
659 * Presentation changes to calendar month view
661 Revision 400.21 2002/09/22 05:20:27 ajc
662 * Began implementing month view
664 Revision 400.20 2002/09/21 04:38:05 ajc
665 * Added utility functions for displaying vcalendar timestamps in web forms
666 and translating form data back to timestamps.
667 * Completed the "edit task" and "add new task" screens.
669 Revision 400.19 2002/09/20 20:28:08 ajc
670 * Smooth transition between "list tasks" & "edit task" screens
672 Revision 400.18 2002/09/20 03:54:44 ajc
673 * Display the "Tasks" view as a bulleted list with each task clickable
674 * Clicking brings up an (unfinished) "edit task" screen
676 Revision 400.17 2002/09/18 21:44:02 ajc
677 * display VTODO parameters
679 Revision 400.16 2002/09/17 04:21:00 ajc
680 * Handler chains for VCALENDAR and VTODO types
682 Revision 400.15 2002/09/17 03:37:10 ajc
683 * Implemented a 'display handler' infrastructure for various groupware types
685 Revision 400.14 2002/09/16 03:35:12 ajc
686 * Just a bunch of glue code to iterate through the various types of ical
687 objects we could encounter
689 Revision 400.13 2002/09/15 04:05:41 ajc
690 * Process calendar object subcomponents
692 Revision 400.12 2002/09/15 03:40:13 ajc
694 * When a text/calendar MIME type is discovered in a message, send it to
695 the (currently skeleton) parser in calendar.c
696 * calendar.c: skeleton parser for calendar objects which currently just
697 creates an icalcomponent object and frees it.
699 Revision 400.11 2002/09/15 03:16:24 ajc
700 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
701 function namespace in libical
703 Revision 400.10 2002/09/15 02:50:55 ajc
704 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
706 Revision 400.9 2002/09/14 21:33:31 ajc
707 * Backed out compression of inlines -- not all browsers appear to handle it
709 Revision 400.8 2002/09/14 20:20:29 ajc
710 * Attempting to push more stuff through compression. I've introduced some
711 sort of deadlock bug that I can't seem to find yet...
713 Revision 400.7 2002/09/14 20:00:22 ajc
714 * Compress output_image() graphics
716 Revision 400.6 2002/09/14 16:26:35 ajc
717 * output_image() now reads the entire image from Citadel into a buffer before
718 sending it to the browser (for performance reasons, and so it can compress)
720 Revision 400.5 2002/09/14 04:52:59 ajc
721 * Look for the "libical" calendaring library and link it in if present...
723 Revision 400.4 2002/09/14 04:02:36 ajc
724 * Finished gzip compression of dynamic pages (when browser supports it)
726 Revision 400.3 2002/09/13 20:40:53 ajc
727 * Detect when the client browser is capable of gzip encoding
728 (actual encoding is not implemented yet)
730 Revision 400.2 2002/09/13 15:54:40 ajc
731 * Reversed the above change because I broke it somehow
733 Revision 400.1 2002/09/11 22:46:59 ajc
734 * Started adding in compression and calendaring library detects (not finished)
736 Revision 400.0 2002/09/09 03:56:11 ajc

741 --> Open links in new window (as with text msgs)
742 --> Convert loose URL's to hot links (as with text msgs)
744 Revision 323.67 2002/09/06 03:59:11 ajc
745 * Added an "About this server" panel to the Summary page.
746 (Useless fluff, but better than an empty column.)
748 Revision 323.66 2002/08/26 02:57:06 ajc
749 * Rooms listed on the summary page are now clickable-gotoable
751 Revision 323.65 2002/08/26 01:24:09 ajc
752 * Added a "summary" page (rather sparse for now)
754 Revision 323.64 2002/08/24 15:30:48 ajc
755 * GET instead of POST for listsub. Also add a 'Back...' link.
757 Revision 323.63 2002/08/24 05:59:24 ajc
758 * Bugfixes and cosmetic changes to listsub system
760 Revision 323.62 2002/08/23 03:37:19 ajc
761 * Finished all of the subscribe/unsubscribe/confirm stuff! (I think)
763 Revision 323.61 2002/08/22 03:55:47 ajc
764 * 'unsubscribe' command (but not 'confirm unsubscribe')
766 Revision 323.60 2002/08/21 21:58:37 ajc
767 * Completed self-service list subscription via web.
768 (Still need to implement unsubscribe.)
770 Revision 323.59 2002/08/16 22:06:51 ajc
773 Revision 323.58 2002/08/16 03:51:12 ajc
774 * I think I've finally nailed the 'no session' pages now...
776 Revision 323.57 2002/08/15 03:49:47 ajc
777 * Fleshed out the list subscription page a bit
779 Revision 323.56 2002/08/13 19:55:12 ajc
780 * Keep track of the HTTP "Host:" header being sent by the browser.
781 (We're going to need this in the near future)

801 Revision 323.49 2002/07/23 04:43:58 ajc
802 * Updated message reading to use the new MSG4 command, so we can do output
803 of various types of richtext (mainly HTML).
805 Revision 323.48 2002/07/16 03:37:24 ajc
806 * Small change to above
808 Revision 323.47 2002/07/16 03:23:37 ajc
809 * Display HTML messages as HTML. (Wow!)
811 Revision 323.46 2002/07/13 04:39:59 ajc
812 * Handle multipart/alternative in a nicer way, giving us the opportunity to
813 output HTML instead of converting to text/plain and back. (Not finished.)
815 Revision 323.45 2002/07/11 03:17:03 ajc
816 * hacks to text_to_server() to transmit messages as HTML
818 Revision 323.44 2002/07/09 04:21:12 ajc
821 Revision 323.43 2002/07/06 03:10:26 ajc

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

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

1093 queue length to 100 for use on big systems. Also, during startup, the
1094 initial startup thread now exits after creating the worker threads, instead
1095 of becoming a worker thread itself. For some reason Solaris had problems
1096 with the latter method.

1229 Revision 211.19 2000/05/18 02:33:39 ajc

1249 big session logjams when either of these conditions are met
1251 Revision 211.14 2000/04/15 15:43:46 nbryant

1438 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1440 among other places, IE 5. Die, Bill, Die.
1442 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1443 * Fixed the behavior of the "forget room" routine, to properly handle
1444 the transition back to the Lobby after it's all done.
1445 * Added ExpressMessageCat() to allow code to send the user messages
1446 along with incoming express messages
1447 * WebCit now sends the name of the end user's browser as the client
1448 name in a Citadel IDEN command rather than its own name.
1450 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1458 * Initial entry to _BASEROOM_ at login now done as a Skip instead
1459 of a Goto, in order to prevent it from first marking all msgs old.
1461 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1462 * Replaced _most_ gotoroom() calls with smart_goto(), a version

1474 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1475 * Reworked a lot of the structure, made more HTML "embeddable"
1476 * Changed the noframes mode to display "fake" frames using tables
1478 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nick@ulster.net>
1479 Changed some output formatting (mainly <FONT> tags).
1480 Changed who.c to use urlescputs() rather than escputs()
1481 in urls so GOTOs and User Profiles work when the string has a
1484 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1485 http://www.webreference.com/dhtml/column18/menuFrLoad.html
1486 How to cause "onLoad=" to cause a sibling frame to refresh without
1487 having to use the nonportable HTTP "Window-Target:" directive. Began
1488 implementation of this; it should allow portable NS/IE compatibility.
1490 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1491 * Implemented "access level required to create rooms"
1493 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1494 * webcit.c: modified getz() to *exit* the program when fgets()
1495 returns an error. This is actually the desired behavior; it would
1496 otherwise busy-loop forever on a broken pipe.
1498 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1499 * webcit.c: added to getz() the ability to return an error code;
1500 implemented this in the main loop, hopefully fixing problems
1501 * Added "braindamage" file (frames/JS browser compatibility list)
1502 * Added HTTP "User-agent:" detection
1503 * wildmat.c, braindamage.c: added
1504 * Initial value of 'noframes' is now set by the braindamage check
1505 * Ran everything through "indent -kr -i8"
1506 * roomops.c: in room list, print a in otherwise empty cells
1508 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
1509 * context_loop.c: warning fix
1510 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
1512 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1513 * Resolve the name of the connecting host and pass it on to Citadel
1515 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1516 * wDumpContent() is now responsible for </BODY></HTML> most of the
1517 time (parameter settable) so that the main menu can easily be
1518 embedded in every page when running in noframes mode
1519 * noframes mode selection is now carried in the cookie
1521 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1522 * Made the frames stuff less dependent on the HTML TARGET= directive
1523 and more dependent on the HTTP Window-target: directive.
1524 * Made the system semi-navigable in noframes mode.
1526 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1527 * Brought over the new room listing code and <G>oto heuristics
1528 from the main Citadel tree, to pay attention to floor/room ordering
1530 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1531 * Modified the back end of mime_parser to use callbacks instead of
1532 doing something specific. Now we can use it elsewhere.
1534 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1535 * Fixed the bugs in "Site-wide configuration"
1536 * Added a "generic server commands" screen
1538 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1539 * Reduced the multiple cookies down to one cookie combining all data.
1541 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1542 * Removed wc_host and wc_port cookies.
1543 * Added an "edit your session" screen to change your wholisting.
1545 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1546 * Added "enter registration"
1547 * Set up automatic trigger of Enter Registration when the server
1549 * Established that a one-to-one WebCit/Citadel correspondence will
1550 be required. No big deal due to shared code segments.
1551 * Added "change password"
1552 * Added networking configuration screens. These still need testing.
1553 * Added a "kill session" link to each line of the wholist when
1554 logged in as an aide, and the screens to perform this operation.
1556 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1557 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).

1566 * Wrote mime_parser.c for handling of image uploads. This will also
1567 be used in future Citadel MIME projects.
1569 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1578 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1579 * Changed the "auto read new" functionality from a meta refresh tag
1580 to an "onload" directive (the former was causing graphics problems)
1581 * Added "create room"
1584 Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1595 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1596 * Replace "Citadel/UX" in menu bar with the Citadel/UX logo
1598 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>

1601 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1602 * context_loop.c: Moved "remove session" into its own function.
1603 Check for dead webcit child process before each transaction.
1604 * Ignore SIGPIPE; this seems to magically make the program bulletproof
1605 against broken HTTP connections.
1606 * Added a housekeeping thread to periodically remove dead sessions
1607 and kill idle sessions.
1608 * messages.c: added "delete message" functionality
1609 * messages.c: added "move message" functionality

1623 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1624 * context_loop.c: After fork(), child process closes the HTTP socket
1625 so when the parent process closes it, it actually _does_ close.
1626 Otherwise, aIEeeee and possibly other browsers will hang.
1627 * Added support for graphics images retrieved from the Citadel server.
1628 * Set up login banner graphic and background image graphic
1630 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

1633 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1634 * Smoothed out some of the login/logout code. Failed authentication
1635 now works the way it should.
1636 * Added support for new user login (still need to handle registration).
1638 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1639 * Discovered that the HTTP socket problem is related to a socket that
1640 isn't properly lingering on close. Temporarily hacked a sleep(10)
1641 into context_loop.c until it is figured out.
1643 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1644 * Did a little debugging, still trying to figure out why logging in
1645 displays "Connection reset by peer" error. It used to work...
1647 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
1648 * Makefile.in: updated dependencies
1650 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

1670 * tcp_sockets.c: getservbyname() doesn't set errno.
1672 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
1673 * webserver.c: warning fix
