2 Revision 528.30 2005/02/01 03:49:09 ajc
3 * Completed "folder list" PROPFIND, now listing all rooms set to a
4 calendar, tasks, or address view, using the GroupDAV properties.
6 Revision 528.29 2005/02/01 02:28:32 ajc
7 * "time(NULL) mod 60" doesn't work for some reason, so it has been removed.
8 When defaulting a new event date/time to now, set the seconds to zero
11 Revision 528.28 2005/01/31 23:31:26 ajc
12 * Initial attempt at GroupDAV PROPFIND for folder enumeration. Hardcoded
13 to only show the Calendar> room. It kinda-sorta works with KOrganizer.
15 Revision 528.27 2005/01/31 16:24:47 ajc
16 * iconbar is now a happy css hovery lightupy div thing
18 Revision 528.26 2005/01/29 03:59:25 ajc
19 * Implemented the GroupDAV DELETE method.
21 Revision 528.25 2005/01/28 05:25:43 ajc
22 * iconbar no longer uses the beginbox/endbox semantics, but instead lives
23 directly inside the iconbar div.
25 Revision 528.24 2005/01/28 05:13:02 ajc
26 * GroupDAV object URL's are now based on the EUID of a message (which is
27 derived from the UID of the groupware object itself) instead of the
28 message number. This was done in order to conform to GroupDAV's
29 requirement that the URL cannot change after an object is updated.
30 * The ETag of a GroupDAV object is still the message number, and in fact
31 doing so meets that requirement perfectly.
33 Revision 528.23 2005/01/26 18:15:34 ajc
34 * PROPFIND now outputs fully qualified URL's
36 Revision 528.22 2005/01/26 18:02:22 ajc
37 * Initial implementation of GroupDAV PROPFIND
39 Revision 528.21 2005/01/26 16:28:23 ajc
40 * Output ETags in double quotes to conform with the new GroupDAV draft.
41 * Output HTTP Server: header in GroupDAV transactions
42 * Server: header now displays both WebCit and Citadel versions
43 * Added groupdav_common_headers() to output HTTP headers common to all
44 GroupDAV transactions (Connection: close, Server: WebCit, etc.)
46 Revision 528.20 2005/01/25 19:51:04 ajc
47 * Accept escaped characters in GroupDAV GET URL's
49 Revision 528.19 2005/01/25 04:17:20 ajc
50 * Implemented the Groupdav GET method, more or less in its final form
51 (still need to fix the room/folder naming semantics)
53 Revision 528.18 2005/01/25 03:12:27 ajc
54 * Completed HTTP "Basic" authentication, and a stub function for the
55 main entry point for GroupDAV functions.
57 Revision 528.17 2005/01/24 03:37:48 ajc
58 * Began laying the groundwork for http-authenticated GroupDAV sessions.
60 Revision 528.16 2005/01/22 22:50:51 ajc
61 * removed descriptions in non-main menus
63 Revision 528.15 2005/01/20 21:24:27 ajc
64 * When viewing a calendar room, the "Read all messages" link in the
65 room banner has been replaced by "Day view" and "Month view" links.
66 (I have also imported icons for week and year views, in case we add
69 Revision 528.14 2005/01/20 16:13:56 ajc
70 * Added in a bunch of stupid JavaScript to allow the instant message
71 window to be dismissed.
73 Revision 528.13 2005/01/20 04:10:41 ajc
74 * Cleaned up a bunch of unused cruft from the old layout
75 * Instant messages are now displayed in a div that layers itself
76 over the rest of the site. It would be nice if we could figure out
77 a way to make a clickable "hide" box...
79 Revision 528.12 2005/01/17 04:38:14 ajc
80 * Navbar is now dynamic, in an attempt to make only the relevant controls
81 appear on any given page.
83 Revision 528.11 2005/01/15 07:19:08 ajc
84 * Removed the fixed pixel width from the tree view room list so it doesn't
85 wrap around in an ugly way on aIEeeee.
87 Revision 528.10 2005/01/15 05:26:27 ajc
88 * Message entry window is now somewhat full screen.
90 Revision 528.9 2005/01/14 21:03:17 ajc
93 Revision 528.8 2005/01/14 15:00:51 ajc
94 * Placed the navbar into the room banner, at least in its temporary form.
96 Revision 528.7 2005/01/14 04:53:54 ajc
97 *** empty log message ***
99 Revision 528.6 2005/01/14 04:53:12 ajc
100 * Got the three-pane model working not only with web browsers, but also
101 with the disgusting abomination called Internet Explorer.
103 Revision 528.5 2005/01/13 18:38:08 ajc
104 * Insert a newline between </div> and <div id="text">
106 Revision 528.4 2005/01/11 16:20:18 ajc
107 * Switching doctype from XHTML to HTML 4.01 STRICT, because nothing handles
110 Revision 528.3 2005/01/11 05:05:08 ajc
111 * *** HUGE CHANGES *** *** WARNING: NOT FULLY FUNCTIONAL ***
112 * Ripped things apart in a big way. The frameset is gone (except for
113 chat, for which we'll probably keep frames). Iconbar and banner are
114 now done using CSS and <div> tags.
115 * Room read/enter/goto controls are currently missing. Stay tuned.
116 * I am in the process of rewriting all of the markup as valid XHTML.
118 Revision 528.2 2004/12/29 22:08:08 ajc
119 * roomops.c: provide a way to create room shares with a mapping to an
120 alternate room name on the other end.
122 Revision 528.1 2004/12/29 17:28:09 ajc
123 * roomops.c: when adding/removing nodes in the 'Sharing' tab, don't go
124 all corrupty-whatever when a remote room name mapping is found. Display
125 the mapping and preserve it across share/unshare operations.
127 Revision 528.0 2004/12/28 03:58:34 ajc
130 Revision 527.1 2004/12/28 03:58:24 ajc
131 * Corrected overly-escaped reply-to addresses in "reply" button
132 * Repaired toggling of self-service account creation in admin screen
133 * Bumped internal version number to 5.28
135 Revision 527.0 2004/12/07 04:41:37 ajc
138 Revision 526.1 2004/12/07 04:41:02 ajc
139 * Finally tracked down the WC->vars heap corruption issue (for real this
140 time). We now call clear_local_substs() at the end of each HTTP
141 transaction, whether we need to or not, instead of calling it whenever
142 we're done with something we wanted session variables for.
143 * Finally tracked down the years-long "misplaced '(edit)' link" bug, by
144 copying serv_info->serv_pid to WC->ctdl_pid at the time it's loaded,
145 preventing it from getting clobbered by another session.
146 * Bumped internal version number to 5.27
148 Revision 526.0 2004/12/01 21:35:56 ajc
151 Revision 525.4 2004/12/01 21:35:44 ajc
152 * Changed internal version number to 5.26
154 Revision 525.3 2004/12/01 21:34:17 ajc
155 * Numerous memory management bugfixes.
157 Revision 525.2 2004/12/01 16:48:24 ajc
158 * tools.c: don't crash when striplt() is called with a zero-length string
160 Revision 525.1 2004/11/12 18:02:36 ajc
161 * Updated the richtext editor (new version from Kevin Roth's site)
163 Revision 525.0 2004/11/03 20:21:10 ajc

169 Revision 524.6 2004/10/20 02:41:41 ajc
171 * Added the notes room to the icon bar
172 * Set up an initial implementation of Notes view. Attractive enough to
173 publish, but read-only. Needs a note editor.
175 Revision 524.5 2004/10/15 03:10:24 ajc
176 * Calendar objects UID now generated by generate_uuid() which creates
177 pseudo-DCE-ish UUID's.
179 Revision 524.4 2004/10/05 01:59:31 ajc
180 * localtime_r() fixes
182 Revision 524.3 2004/10/03 02:56:35 ajc
183 * Added a pthread_attr_destroy() in the appropriate place (thanks fleeb!)
185 Revision 524.2 2004/10/01 16:23:23 ajc
186 * Set up framework for "notes" view, and added a skeleton function for
189 Revision 524.1 2004/09/30 03:44:01 ajc
190 * fix line width break problem in chat
192 Revision 524.0 2004/09/28 16:12:44 ajc
195 Revision 523.12 2004/09/28 16:12:30 ajc
196 * Prepare for 5.24 release
198 Revision 523.11 2004/09/27 02:17:47 ajc

200 * floors.c: fix a warning message
202 Revision 523.10 2004/09/25 03:34:21 ajc
203 * summary.c: Fixed a calling syntax problem

206 * small stylesheet fix
208 Revision 523.8 2004/09/24 04:21:41 ajc
209 * Fixed display bug for room list mode when we dropped down multiple
210 sublevels at once (such as, from 3 to 1 instead of from 2 to 1)
212 Revision 523.7 2004/09/24 04:08:25 ajc
213 * Put our <SPAN> tags back in to denote floors, rooms with new msgs, and
214 rooms without new msgs
216 Revision 523.6 2004/09/24 04:04:34 ajc
217 * "folders view" of room list now uses Dave Lindquist's "menuExpandable3"
220 Revision 523.5 2004/09/23 03:21:10 ajc
221 * roomops.c: "folders" view of rooms is an actual Unnumbered List now.
223 Revision 523.4 2004/09/16 02:42:37 ajc
224 * Set default view of new rooms during CRE8 command instead of afterwards
226 Revision 523.3 2004/09/15 03:08:50 ajc
227 * Support config of seaperate MSA port in Citadel 6.26
229 Revision 523.2 2004/09/10 03:49:17 ajc
230 * Added 'dialog' mode to setup
232 Revision 523.1 2004/08/31 20:31:01 ajc
233 * When saving VTODO (tasks), insert a UID if none is already present. Also
234 increment the sequence, or insert one if none is already present.
236 Revision 523.0 2004/08/31 03:02:37 ajc
239 Revision 522.30 2004/08/31 03:02:28 ajc
240 * Changed internal version number to 5.23
242 Revision 522.29 2004/08/27 02:40:06 ajc
243 * Ditched the graphical buttons because CSS can do the same thing faster.
245 Revision 522.28 2004/08/18 03:16:12 ajc
246 * 'move' and 'delete' buttons only show when allowed to do those things
248 Revision 522.27 2004/08/18 02:10:17 ajc
249 * Reply/Move/Delete buttons are now images, because system-native buttons
250 were too big and ugly.
252 Revision 522.26 2004/08/11 17:24:57 ajc
253 * static/iconbar.html: removed.
254 * Updated the "powered by citadel" graphic
256 Revision 522.25 2004/08/11 03:49:15 ajc
257 * Replaced all instances of the name "Citadel/UX" with "Citadel"
258 * Installed the "simple logo" in the iconbar
260 Revision 522.24 2004/08/09 03:11:20 ajc
261 * Changed DOCTYPE to HTML 3.2 because that's really what it resembles
263 Revision 522.23 2004/08/05 21:32:17 ajc
264 * Reply/Move/Delete are now buttons instead of links. This should enable
265 us to add some JavaScript magic for "Reply quoted" ...
267 Revision 522.22 2004/08/05 02:47:21 ajc
268 * Removed the "pull_quote" style and used the <BLOCKQUOTE> tag instead. It
269 has a more predictable and attractive behavior, and can still be
270 overridden in the style sheet if the site operator wants to.
272 Revision 522.21 2004/08/04 03:52:23 ajc
273 * Tasks view is now pretty.
274 * Tasks view now displays date due for each task.
275 * Tasks view is now sorted by date due.
276 * Tasks view now displays overdue tasks in red.
278 Revision 522.20 2004/08/03 03:55:37 ajc
279 * Tasks view now uses the same buffer/dump logic as the calendar views, so
280 we can sort them by due date and do a prettier display. (Only the logic is
281 changed so far. The prettier display is forthcoming.)
283 Revision 522.19 2004/07/21 02:57:09 ajc
284 * Internet Configuration screen looks a little neater now
286 Revision 522.18 2004/07/21 02:45:15 ajc
287 * Completed the "Internet Configuration" screen
289 Revision 522.17 2004/07/16 19:13:37 ajc
290 *** empty log message ***
292 Revision 522.16 2004/07/16 19:13:10 ajc
293 * tools.c: display 12:00 as 12pm, not 12am
295 Revision 522.15 2004/07/16 03:14:03 ajc
296 * more work on inetconf screen
298 Revision 522.14 2004/07/16 02:50:00 ajc
299 * useredit.c: put a pretty box around user editing
301 Revision 522.13 2004/07/13 03:25:08 ajc
302 * inetconf.c: added. Not finished yet.
304 Revision 522.12 2004/07/10 03:10:19 ajc
305 * Completed web screens for THE DREADED AUTO-PURGER by adding room and
306 floor level configurations.
307 * Put a space between OK and CANCEL buttons anywhere in the system where
309 * Some more of the room config/admin screens now return to themselves
310 with a "ok, you did that" message when OK is pressed, instead of dropping
311 out to the main menu.
313 Revision 522.11 2004/07/08 03:03:01 ajc
314 * Added global settings for THE DREADED AUTO-PURGER to the site-wide
315 configuration (public rooms default and mailboxes default). Still need
316 to add floor and room policy screens.
318 Revision 522.10 2004/07/02 03:28:08 ajc
319 * Much-improved alphabet tabs for Address Book view. Now divides the
320 total number of names by (names per page, currently 60) and sets up
321 that many tabs, with proper [Aaa-Bbb] labels on them.
323 Revision 522.9 2004/07/02 03:26:06 ajc
324 *** empty log message ***
326 Revision 522.8 2004/07/01 02:40:40 ajc
327 * Clicking "Enter a message" in a groupware room now automatically calls
328 the correct editor for the type of objects in the room (message, calendar
329 event, task, address book entry)
331 Revision 522.7 2004/06/29 17:21:25 ajc
332 * Removed the word "room" in a few locations, as part of our push towards
333 not looking like a BBS when running in groupware mode
335 Revision 522.6 2004/06/29 00:37:02 ajc
336 * Made some fonts bigger because users were complaining...
338 Revision 522.5 2004/06/27 03:02:05 ajc
339 * Summary view -- always view ALL messages
340 * Summary view -- new messages are in boldface
342 Revision 522.4 2004/06/24 20:42:14 ajc
343 * Added the "server ip address" Citadel config option
344 * Site config: added "Changes will not take effect until..." language
347 Revision 522.3 2004/06/24 14:50:35 ajc
348 * Added the ability to listen on a single IP address instead of all addresses.
350 Revision 522.2 2004/06/22 02:21:56 ajc
353 Revision 522.1 2004/06/21 15:00:52 ajc
356 Revision 522.0 2004/06/19 03:21:35 ajc
359 Revision 521.10 2004/06/19 03:11:07 ajc
360 * Instead of a crufty "the topmost Internet email address will be used
361 for outgoing email" explanation, separated it into "Primary Internet
362 email address" and "Other email addresses" boxes.
364 Revision 521.9 2004/06/19 02:42:12 ajc
365 * Removed the "aides access to mailboxes" config option, which is no longer
366 part of the Citadel system.
368 Revision 521.8 2004/06/16 02:07:22 ajc
369 * Removed a couple of lines of debugging code leftover from last night
371 Revision 521.7 2004/06/15 03:06:11 ajc
372 * Bumped internal version number to 5.22
373 * Use new fast headers-only-no-mime fetch mode in Citadel for
376 Revision 521.6 2004/06/15 02:30:21 ajc
377 * Honor "maxmsgs" even when viewing a mailbox in summary mode
379 Revision 521.5 2004/06/12 04:26:38 ajc
380 * Fixed some garbled output resulting from turning things that look like
383 Revision 521.4 2004/06/11 16:09:36 ajc
384 * Moved the room graphic to the left of the room name in the banner, to
385 make it more consistent with the rest of the site.
386 * Reduced the size of the font in the iconbar
388 Revision 521.3 2004/06/11 03:15:08 ajc
389 * When "Add" is clicked without specifying an upload filename, resume
390 composition instead of aborting the post.
391 * Add attachments to messages in forward order, not reverse order
393 Revision 521.2 2004/06/10 03:08:48 ajc
394 * Improved the appearance of tabs in the room config screen
396 Revision 521.1 2004/06/10 02:58:55 ajc
397 * Made all the title boxes the same background color. The old scheme was
398 cute but not professional looking.
400 Revision 521.0 2004/06/06 19:53:25 ajc
403 Revision 510.15 2004/06/06 19:32:15 ajc
404 * Cleaned up a couple of FIXME's sitting around in the code
405 * Altered the conditions under which stray http://... strings are
406 automatically turned into links, to prevent that logic from
407 transforming IMG tags into gibberish.
408 * Set internal version number to 5.21
410 Revision 510.14 2004/06/04 02:29:07 ajc
411 * Fixed bug in "validate new users" screen (thanks Campy)
413 Revision 510.13 2004/06/03 03:21:22 ajc
414 * "Reply" button now carries the message subject into the reply.
416 Revision 510.12 2004/06/02 02:07:54 ajc
417 * setup.c: updated the setup script to configure two /etc/inittab entries,
418 one for http and one for https.
420 Revision 510.11 2004/06/01 21:46:47 ajc
421 * crypto.c: when an SSL connection errors out (and closes) unexpectedly
422 during a read or write operation, do not attempt to finish the operation
423 unencrypted like we do in Citadel. Here in WebCit land it only causes
424 the server to segfault.
426 Revision 510.10 2004/06/01 19:01:22 ajc
427 * netconf.c: widened some of the text entry fields
428 * webcit.h: bumped up the internal version number to 5.20
430 Revision 510.9 2004/06/01 18:44:20 ajc
431 * Return to the old command-line usage (-s for https, service is either
432 http or https but not both)
434 Revision 510.8 2004/06/01 03:32:28 ajc
435 * Add "permanent room" setting to room edit screen
436 * create room -- allow longer strings
438 Revision 510.7 2004/06/01 00:36:43 ajc
439 * Hmmph. Do the session cookie as hex instead of base64. There really
440 are some characters in the base64 set that make HTTP do nasty things.
442 Revision 510.6 2004/05/31 21:43:27 ajc
443 * Added "|END" to the session cookie before base64-ing it. This fixes a
444 problem with certain room names causing the webserver to freak out and
445 break embedded images and stuff. I don't know why.
447 Revision 510.5 2004/05/31 20:34:11 ajc
448 * Message entry using Kevin Roth's excellent cross-platform richtext
451 Revision 510.4 2004/05/31 15:54:13 ajc
452 * "text" and "HTML" options for message entry.
454 Revision 510.3 2004/05/29 03:31:48 ajc
455 * tighten up the space between icons in the iconbar
457 Revision 510.2 2004/05/28 20:24:53 ajc
460 Revision 510.1 2004/05/24 03:02:38 ajc
461 * CSS change to make folder names stand out more in the "Folder View"
463 Revision 510.0 2004/04/30 04:08:58 ajc
466 Revision 506.13 2004/04/30 04:08:47 ajc
467 * Changed internal version number to 5.10
468 * Updated documentation for the new HTTPS service
470 Revision 506.12 2004/04/27 03:21:36 ajc
471 * Prompt for HTTPS port number during setup. We may make this optional.
473 Revision 506.11 2004/04/27 03:16:31 ajc
474 * When running on the same host as Citadel, if no key/cert are found,
475 symlink to Citadel's if possible.
476 * One server binary now forks to start both http and https servers.
478 Revision 506.10 2004/04/21 03:43:39 ajc
479 * Completed remaining SSL fixes. Works in Moz, aIEeee, Konq; self-signed
480 certs are also no longer invalid.
482 Revision 506.9 2004/04/21 02:25:13 ajc
483 * Replaced ctdl_install_certificate() with convenience functions found
484 in the OpenSSL library.
486 Revision 506.8 2004/04/21 02:19:41 ajc
487 * Got HTTPS to work with Mozilla (by twiddling stuff that I still don't
488 understand, but read at http://www.informit.com/articles/article.asp?p=22078
489 ). Still doesn't work with Internet Monopolizer, though.
491 Revision 506.7 2004/04/20 02:32:44 ajc
492 * Allow setup to run seamlessly from within the Citadel Ridiculously
493 Easy Installer by observing the values of environment variables
494 CITADEL_INSTALLER, CITADEL, and WEBCIT.
496 Revision 506.6 2004/04/20 02:02:50 ajc
499 Revision 506.5 2004/04/16 03:14:06 ajc
500 * Minor fix for previous checkin
502 Revision 506.4 2004/04/16 02:59:01 ajc
503 * Completed SSL support. Still doesn't work with all browsers... gotta
506 Revision 506.3 2004/04/15 03:57:00 ajc
507 * Brought over the SSL/TLS stuff from Citadel. I think it's complete but
508 it has a crashy crashy bug in it. Don't use it yet.
510 Revision 506.2 2004/04/13 19:41:36 ajc
511 * GET /freebusy/user.vcf *and* /freebusy/user.vfb now both work.
512 (freebusy data fetch for anonymous Kolab type clients)
514 Revision 506.1 2004/04/10 04:32:59 ajc
515 * Fixed some version and copyright date oopses
517 Revision 506.0 2004/04/10 04:29:30 ajc
520 Revision 505.22 2004/04/10 04:29:20 ajc
521 * Changed internal version number to 5.06
523 Revision 505.21 2004/03/29 04:30:20 ajc
524 * configure.in, Makefile.in: handle $LDFLAGS
526 Revision 505.20 2004/03/20 05:03:14 ajc
527 * Original startup thread becomes a worker thread after initialization.
528 Doing otherwise turns it into a zombie (at least on Linux) and possibly
529 leads to other problems
530 * Filter out NOOP's received in chat
532 Revision 505.19 2004/03/18 04:32:24 ajc
533 * Removed the language in README.TXT which told everyone that chat wouldn't
534 work with a non-local Citadel server, because that's no longer true.
535 * Removed the old chat applet from the static/ directory
537 Revision 505.18 2004/03/18 04:00:44 ajc
538 * Rounded web boxes now look correct in all browsers.
540 Revision 505.17 2004/03/17 18:25:31 ajc
541 * When creating a new user, auto-chain to the "edit user configuration"
542 screen, and subsequently auto-chain to the "edit address book entry"
543 screen. This creates a nice sensible workflow.
545 Revision 505.16 2004/03/15 22:47:09 ajc
546 * Prettied up the chat window a little more.
548 Revision 505.15 2004/03/15 04:27:44 ajc

558 * Fix the current view not being set to the default view for the creator
561 Revision 505.12 2004/03/07 21:31:17 ajc
562 * serv_read() now zeroes out the supplied buffer (with the supplied
563 length) if a server read fails. This causes serv_gets() to return
564 instead of looping endlessly. Fixes chat problem found on linux-ppc.
566 Revision 505.11 2004/03/03 05:21:36 ajc
567 * Made the chat screen totally kick-ass sweet. The flickering reload
568 i-frame is now tiny and hidden, and it *appends* new chat data to
569 the viewable window using JavaScript. No flickering + scrollback!
570 * Added a help button to the chat screen.
572 Revision 505.10 2004/02/29 22:52:15 ajc
573 * Close and clear (set to -1) server socket handle when socket errors are
574 detected. Fixes a chat problem reported by Winzlo.
576 Revision 505.9 2004/02/29 05:34:25 ajc
577 * Display the Chat menu option as "Chat with other users in <roomname>"
579 Revision 505.8 2004/02/27 05:04:38 ajc
580 * fix frameset bug in page popups
582 Revision 505.7 2004/02/26 04:08:56 ajc
583 * Fixed a problem that made WebCit go to the "no cookies" screen instead
584 of the logout banner.
585 * Ford's latest stupid room has a name with more than 64 characters, and
586 we still had a 64-byte room name in the march_list struct. ooooops...
588 Revision 505.6 2004/02/26 03:07:26 ajc
589 * Put the /favicon.ico --> /static/favicon.ico hack back in. Why not?
591 Revision 505.5 2004/02/25 23:10:28 ajc
592 * Allow "/do_logout" as a no-frames page
594 Revision 505.4 2004/02/25 23:00:21 ajc
595 * Changed the favicon support to LINK tags in the HEAD of static stuff,
596 to make life easier. (Thanks to prosthetik for this)
598 Revision 505.3 2004/02/25 15:20:11 ajc
599 * Support for favicon.ico in the static/ directory
601 Revision 505.2 2004/02/24 04:06:42 ajc

605 * Replaced the Java chat with a new system based on IFRAME's and JavaScript
607 Revision 505.0 2004/02/19 03:32:50 ajc
610 Revision 504.7 2004/02/19 03:32:38 ajc
611 * Changed the internal version number to 5.05
612 * Completed the frames fix
614 Revision 504.6 2004/02/18 20:08:29 ajc
615 * Fixed the frameset force reload logic. Now it does the whole frameset
616 without displaying an error in the main frame.
618 Revision 504.5 2004/02/18 19:17:51 ajc
619 * Force reload of frameset if someone tries to escape it. Not perfect
620 but it mostly works at this poing.
622 Revision 504.4 2004/02/17 03:37:11 ajc
623 * Indicate to Citadel that we want Server Generated Invitations when
624 calendar events are saved. (No longer the default in Citadel server.)
626 Revision 504.3 2004/02/09 04:49:32 ajc
627 * Prepare for a way to avoid falling out of the main frameset
629 Revision 504.2 2004/02/09 03:37:57 ajc
630 * Changed the thread pool management algorithm. Detecting idle time between
631 socket accepts was not working reliably on all systems, so we now follow
632 the same algorithm as the Citadel server (spawn more threads when number
633 of sessions < number of threads, but keep constrained to pre-defined
634 minimum and maximum thread count)
636 Revision 504.1 2004/02/03 03:09:51 ajc
639 Revision 503.0 2004/01/28 04:31:31 ajc
642 Revision 502.4 2004/01/28 04:30:48 ajc
643 * Create Room can now offer calendar and address book rooms

647 * Split the config for LDAP Connector into its own panel
649 Revision 502.2 2004/01/17 04:32:54 ajc
650 * Add site config options for Citadel servers which support LDAP
652 Revision 502.1 2003/10/24 02:50:19 ajc
653 * Clicking "Enter Message" in a room with an Address Book view opens
654 a blank vCard entry screen.
656 Revision 502.0 2003/10/23 03:16:50 ajc
659 Revision 501.2 2003/10/23 03:07:54 ajc
660 * event.c: Found and removed another unquoted multi-line string literal
661 * webcit.h: changed an #ifdef HAVE_ICAL_H
662 to #ifdef WEBCIT_WITH_CALENDAR_SERVICE to avoid false positives
664 Revision 501.1 2003/10/22 01:42:12 ajc
665 * iconbar.c: removed a stray character or two...
667 Revision 501.0 2003/10/21 04:26:37 ajc
670 Revision 500.30 2003/10/21 04:26:27 ajc

674 * Finished prettying up the vCard display
676 Revision 500.28 2003/10/17 02:31:45 ajc
677 * Multi-line string literals are deprecated in GCC 3.1 unless each line
678 is wrapped in quotes. Performed this fix so it'll compile.
679 * setup.c: removed references to unused variable tempfile[]
681 Revision 500.27 2003/10/09 03:17:02 ajc
682 * Started prettying up the vCard display.
684 Revision 500.26 2003/10/08 02:33:49 ajc
685 * Begin work on better handling of vCard display
687 Revision 500.25 2003/09/04 03:41:27 ajc
688 * siteconfig.c: changed some config items to drop-down boxes
690 Revision 500.24 2003/08/27 04:26:54 ajc
691 * Split the site configuration screen up into four different screens,
692 and added a meta-menu
694 Revision 500.23 2003/08/24 03:31:50 ajc
695 * Finished the setup program
696 * Bumped the internal version number to 5.01
698 Revision 500.22 2003/08/22 00:47:27 ajc
699 * setup is now working, but it still needs a way to detect a running WebCit
701 Revision 500.21 2003/08/22 00:25:40 ajc
702 * Added a skeleton "setup" program to the tree. It does not work yet.
704 Revision 500.20 2003/08/20 03:48:55 ajc
705 * Added iconbar shortcut to Contacts room
706 * Minimum required Citadel is now 6.11
708 Revision 500.19 2003/08/20 03:07:25 ajc
709 * Address book "single card" view now suppresses "reading nn message" and
710 instead shows the letter indices across the top
711 * Clicking on an address in a vCard now connects to WebCit mail instead
712 of a browser mailto: link
714 Revision 500.18 2003/08/19 04:18:43 ajc
715 * Changed things around in the address book view. Made it sorted and
716 more clickable and better looking...
718 Revision 500.17 2003/08/12 18:54:03 error
719 * messages.c: fix off-by-one-error in selector bar
721 Revision 500.16 2003/08/07 22:18:03 ajc

724 Revision 500.15 2003/08/07 03:51:51 ajc
725 * Customizable icon bar as: pictures and text, pictures, text
727 Revision 500.14 2003/08/05 03:52:14 ajc
728 * First working version of the customizable iconbar. It contains a basic
729 set of options and now automatically refreshes when it's customized.
731 Revision 500.13 2003/08/04 03:50:29 ajc
732 * First cut at the customizable iconbar is done. A bunch of generic options
733 are there. Still need to get the actual iconbar to refresh when changes
736 Revision 500.12 2003/08/03 21:02:01 ajc
737 * More work on customizable iconbar
739 Revision 500.11 2003/08/02 05:25:46 ajc

743 * Add config.c_purge_hour to config screen
745 Revision 500.9 2003/07/06 22:06:59 ajc
746 * When converting "anything that looks like a URL" to a real link, first
747 make sure that it isn't already inside a link. This fixes most of the
748 long, ugly URL strings sent by eBay.
749 * Automatically dismantle mailto: links in HTML messages, and convert
750 them to WebCit mail links (clicking on it sends the user to the Mail
751 room and begins composing a new message with the recipient and subject
752 fields pre-populated).
754 Revision 500.8 2003/06/29 20:51:21 ajc
755 * Worked around a rendering bug in Satan's Browser that was causing it
756 to draw the calendar month view much wider than the actual screen wdith
758 Revision 500.7 2003/06/28 04:09:37 error
759 * roomops.c: Backout change to display one less box in the first column in
760 roomlist view, it doesn't seem to work for everyone
762 Revision 500.6 2003/06/28 03:52:51 error
763 * Don't tell browsers not to cache static documents
765 Revision 500.5 2003/06/28 03:35:23 error
766 * roomops.c: Display one less floor in the first column in romlist view
768 Revision 500.4 2003/06/26 03:37:58 ajc
769 * Allow anonymous HTTP requests for /freebusy/user%20name.vcf (or .vfb)
770 This will allow some groupware clients to browse the free/busy times of
771 other users on the system.
773 Revision 500.3 2003/06/21 05:17:21 ajc
774 * Better alignment of system messages
775 * Exterminated display_error() and replaced it with WC->ImportantMessage
776 which is displayed in a bubble on top of whatever page you're on next.
777 * Small cosmetic changes
778 * Fixed some nesting problems in output_headers()
780 Revision 500.2 2003/06/20 03:39:27 ajc
781 * Optimization to floor layout in box view
783 Revision 500.1 2003/06/20 03:04:26 ajc
784 * "Reply" button on messages now handles IGnet recipients correctly
786 Revision 500.0 2003/06/10 04:23:08 ajc
789 Revision 410.50 2003/06/10 04:22:58 ajc
790 * Updated docs and headers for 5.00 release
792 Revision 410.49 2003/06/10 04:05:23 ajc
793 * De-tabled the left side icon bar and reduced one of the graphics, so
794 that all of the rounded corners show up in Satan's Browser.
796 Revision 410.48 2003/06/10 03:47:41 ajc
797 * style.css: added font selection to default <BODY> tag
799 Revision 410.47 2003/06/06 03:26:03 ajc
800 * Satan's Browser insists on putting bloody acres of whitespace to the
801 right of any bulleted list items, making any multi-column table containing
802 a list take more than the entire screen. Removed all such lists so it
803 looks ok. If you are reading this and you are a Microsoft employee, please
804 commit suicide before you break anything else.
806 Revision 410.46 2003/06/06 02:22:07 ajc
807 * Changed the upper left and upper right bounded box corners to a solid
808 blue (#204B78) instead of gradiated, because it was looking funny in
809 256-color mode. It also looked funny in Internet Explorer, but people
810 who use Internet Explorer are contributing to terrorism and really don't
811 deserve Web access in the first place. So I really just fixed this to make
812 it look good in 256-color Netscape.
814 Revision 410.45 2003/06/05 21:37:37 ajc
815 * Cosmetic changes. Attempting to fix b0rken rendering of main menu
816 in b0rken IE browser. Die, Bill, Die.
818 Revision 410.44 2003/06/05 03:52:29 ajc
819 * Buncha cosmetic changes
821 Revision 410.43 2003/06/04 03:41:25 ajc

823 room list -- now defined using CSS
825 Revision 410.42 2003/06/03 03:57:42 ajc
826 * Tightened up the room banner a bit. Smaller padding, smaller font,
829 Revision 410.41 2003/05/31 21:36:45 ajc
832 Revision 410.40 2003/05/26 21:05:42 ajc
833 * availability.c: brought over ical_ctdl_is_overlap() from Citadel. Used
834 it to complete the free/busy checking for attendee availability.
836 Revision 410.39 2003/05/26 05:44:45 ajc
837 * event.c: fix compiler warning

844 * serv_func.c: added utility function read_server_text()
845 * availability.c: banged out more of this code -- still not complete
847 Revision 410.36 2003/05/26 03:28:02 ajc
848 * Getting closer to doing the availability check. Created new source
849 module 'availability.c' for this purpose. Stub function is in place.
851 Revision 410.35 2003/05/25 04:25:12 ajc
852 * siteconfig.c: fixed a spelling error
853 * event.c: add a "Check attendee availability" button, and the code to
854 bypass saving the event to the server, do something with it, and then
855 feed the twiddled data structure back to the form display function for
856 further editing. What's still missing is the code to do the actual
859 Revision 410.34 2003/05/24 22:22:35 ajc
860 * Small stylesheet hack to make it work with b0rken IE
862 Revision 410.33 2003/05/24 22:13:08 ajc
863 * Changed the login banner a bit
865 Revision 410.32 2003/05/20 03:25:41 ajc

868 Revision 410.31 2003/05/19 19:55:09 ajc
869 * summary.c: eliminate compiler warnings about unused variables when
870 compiling a WebCit service without calendar support
872 Revision 410.30 2003/05/18 02:05:33 ajc
873 * More conversion of screens to the new look-and-feel.
875 Revision 410.29 2003/05/16 04:11:29 ajc
876 * We don't need no steenking workaround. Problem fixed. MIME parser not
877 broken. Web server was calling it with bad parameters. All fixed now.
878 * Slightly tweaked the look of the tabs in the room edit screen. Still looks
881 Revision 410.28 2003/05/15 04:52:26 ajc
882 * Minor workaround in web forms to handle mime parser problem in uploads
884 Revision 410.27 2003/05/15 03:35:59 ajc
885 * look and feel overhaul -- almost done!
887 Revision 410.26 2003/05/14 03:46:35 ajc
888 * More background cleanup
890 Revision 410.25 2003/05/05 17:19:46 ajc
891 * Cleanups to summary page when running on a non ical enabled system
892 * Use non breaking spaces in summary page box titles
894 Revision 410.24 2003/05/04 04:22:41 ajc
895 * Display body of messages on a white background. I am doing this in order
896 to prepare for making the general background of the screen a darker color.
898 Revision 410.23 2003/05/04 02:54:55 ajc
899 * Summary page now uses our cutesy new rounded window boxes
901 Revision 410.22 2003/05/03 21:28:41 ajc
902 * Added in a slick new box style and put the room lists in it
904 Revision 410.21 2003/05/03 16:57:04 ajc
905 * In the 'folders' and 'portal' views, change the folder delimiter
906 from / to \ to avoid conflict with room names that have slashes
908 Revision 410.20 2003/05/03 16:23:29 ajc
909 * Enforce three columns in portal view of room list
911 Revision 410.19 2003/05/03 04:52:32 ajc
912 * Added an experimental new "portal view" to the room list options
914 Revision 410.18 2003/05/02 03:23:41 ajc
915 * Minor change to room list algorithm
917 Revision 410.17 2003/05/01 15:33:05 ajc
918 * Fixed a potential memory leak in enumeration of MIME parts
920 Revision 410.16 2003/05/01 03:11:35 ajc
921 * When static content is requested, fetch it without trying to connect
924 Revision 410.15 2003/04/30 05:00:00 ajc
925 * Added the ability to compose messages with file attachments uploaded from
928 Revision 410.14 2003/04/27 04:46:02 ajc
929 * Replace LKRN/LKRO in "folders view" room list with a single LKRA that
930 observes the flag designating the presence of new messages. (The "rooms
931 view" uses an LKRN/LKRO pair *per floor* and has the same inefficiency,
932 but that view may get axed soon.)
934 Revision 410.13 2003/04/26 21:57:53 ajc
935 * tcp_sockets.c: when an outgoing socket connection fails, close the socket
936 before returning an error code to avoid a file descriptor leak
938 Revision 410.12 2003/04/19 21:42:36 ajc
939 * Repaired all my b0rken COLOR tags
940 * Replaced most FONT tags with SPAN tags
943 Revision 410.11 2003/04/19 19:58:10 ajc
944 * Lots of great changes from Nick to make the site CSS-enabled.
946 Revision 410.10 2003/04/14 04:04:40 ajc
947 * First cut of CSS-izing WebCit. Probably b0rken.
949 Revision 410.9 2003/04/09 04:02:32 ajc
950 * Remove the defaulthost/defaultport vs. c_host/c_port stuff -- we haven't
951 supported the idea of one WebCit connecting to multiple Citadels for a
952 long time. Now it's just one set of variables, called ctdlhost/ctdlport.
953 * When connecting to Citadel through a Unix domain socket, don't try to make
954 the Java chat applet available.
956 Revision 410.8 2003/03/31 03:32:19 ajc
957 * messages.c: check for 000 terminator while parsing RFC822 headers to
958 prevent getting hung up while displaying certain badly formatted messages.
960 Revision 410.7 2003/03/30 06:13:19 ajc
961 * When reading from the server, do not treat CR as end-of-line because
962 there's probably an LF coming after it. Instead, keep reading to the LF
964 * Do not underline links in the icon bars
966 Revision 410.6 2003/03/17 04:17:41 ajc
967 * Call to accept() was being made with an uninitialized variable for the
968 third argument. Changed the second and third argument to NULL and 0 because
969 we don't really need accept() to fill up a buffer full of information that
970 we'll never use. (Thanks to SteveV for reporting the bug and helping to
972 * Removed the mutex wrapper around select() because we don't need it. All
973 idle worker threads now block on select() and one of them will wake up when
974 a connection arrives.
976 Revision 410.5 2003/03/15 20:55:03 ajc
977 * When a requested image is not available on the Citadel server, send a
978 1x1 transparent GIF instead of 404 error.
980 Revision 410.4 2003/03/14 04:21:57 ajc
981 * clone events to be encapsulated before saving, because the original
982 instance may already have a parent, and that makes crashy crashy
984 Revision 410.3 2003/03/13 05:57:17 ajc
985 * More encapsulation. Warning: there are bugs in this!!
987 Revision 410.2 2003/03/13 05:20:23 ajc
988 * Various changes to the calendar service to handle messages containing
989 fully encapsulated VCALENDAR components instead of only unencapsulated
990 VEVENT subcomponents. We have to move in this direction for compatibility
993 Revision 410.1 2003/03/01 22:07:19 ajc
994 * New user registration, as well as existing user re-registration, now
995 uses the vCard editing screen.
996 * Administratively editing users' address book entries now works again,
997 mainly due to a fix in the Citadel server. Now requiring Citadel 6.06
998 in order to enforce this.
1000 Revision 410.0 2003/02/19 03:49:33 ajc
1003 Revision 400.90 2003/02/19 03:49:17 ajc
1004 * latest config.guess and config.sub from www.gnu.org
1006 Revision 400.89 2003/02/07 04:44:17 ajc
1007 * Replaced sleep() with a function that sleeps using select() in order to
1008 avoid potential issues with SIGALRM. Possible fix for weird behavior
1009 when running on a Macintosh.
1011 Revision 400.88 2003/01/29 22:32:07 ajc
1012 * Shuffled some code and comments around; minor cleanup
1014 Revision 400.87 2003/01/28 15:37:12 ajc
1015 * All functions which read binary data from the server now make use of the
1016 read_server_binary() function in tools.c
1017 * Binary reads from server now have safety code to prevent infinite loops
1018 * All output of MIME objects is now done with http_transmit_thing()
1020 Revision 400.86 2003/01/19 06:28:04 ajc
1021 * Minimum required Citadel version 6.05
1023 Revision 400.85 2003/01/16 04:41:26 ajc
1024 * When displaying edit controls for time of day in the calendar, only show
1025 minutes that are multiples of 5 ... unless the existing value is not a
1026 multiple of 5, in which case we show that too.
1028 Revision 400.84 2003/01/15 17:34:04 ajc
1029 * event.c: fixed a misspelling
1030 * config.guess, config.sub: updated using latest from ftp.gnu.org
1032 Revision 400.83 2003/01/14 04:21:27 ajc
1033 * Only offer views which make sense for the default view of a room
1035 Revision 400.82 2003/01/13 03:34:33 ajc
1036 * Get ready for the 4.10 release
1038 Revision 400.81 2003/01/12 23:22:53 ajc
1039 * configure.in: check for libical v0.24 or newer
1041 Revision 400.80 2003/01/07 04:56:17 ajc
1042 * Complete the free/busy transparency handling in the form
1043 * Default times for new events are now in the correct timezone
1045 Revision 400.79 2003/01/06 18:01:35 ajc
1046 * Begin handling of TRANSP property to show event times as free or
1047 busy (not finished).
1049 Revision 400.78 2003/01/05 21:02:14 ajc
1050 * Summary page: three columns are now all the same width
1052 Revision 400.77 2003/01/05 20:56:05 ajc
1053 * minor fix for previous checkin
1055 Revision 400.76 2003/01/05 20:51:01 ajc
1056 * Display PARTSTAT for attendees
1058 Revision 400.75 2003/01/05 05:01:00 ajc
1059 * Add "today's calendar events" to the summary page.
1061 Revision 400.74 2003/01/05 04:27:28 ajc
1062 * Add "Tasks" to the summary page
1064 Revision 400.73 2002/12/28 05:44:09 ajc
1065 * ical_dezonify.c: brought over new version from the Citadel source (again)
1067 Revision 400.72 2002/12/28 05:12:45 ajc
1068 * ical_dezonify.c: brought over new version from the Citadel source.
1070 Revision 400.71 2002/12/26 04:04:48 ajc
1071 * Perform CHEK command when automatically establishing sessions, not just
1072 when one is explicitly created. Some stuff is missing otherwise.
1074 Revision 400.70 2002/12/25 23:18:06 ajc
1075 * Be more strategic about when to call ical_dezonify()
1076 (This may be the last set of fixes. I hope so.)
1078 Revision 400.69 2002/12/25 21:39:38 ajc
1079 * ical_dezonify.c: added.
1080 * calendar.c: convert incoming ical messages to UTC
1081 (the usual routines will then convert them to local time for display)
1083 Revision 400.68 2002/12/25 07:06:00 ajc
1084 * Tweaked the code to work with libical 0.24
1086 Revision 400.67 2002/12/20 04:50:00 ajc
1087 * When saving a calendar event, increment the SEQUENCE property.
1089 Revision 400.66 2002/12/18 05:03:39 ajc
1090 * In the calendar code, changed all "struct tm *" to "struct tm" and changed
1091 all "tm = localtime(foo)" to "memcpy(&tm, localtime(foo), sizeof(struct tm))"
1092 Because the libc-allocated buffer was getting clobbered.
1093 * This fixes the problem fleeb reported with Feb 1 events making it go nuts.
1095 Revision 400.65 2002/12/17 05:01:39 ajc
1096 * Prettied up the calendar day view layout
1097 * Hour/minute editing fields now use am/pm hours and 2-digit minutes
1099 Revision 400.64 2002/12/16 04:43:30 ajc
1100 * Correctly handle local time zone when figuring out which day and time to
1101 display events on calendar month/day views. This also seems to have
1102 fixed the bug that was causing events to sometimes get lost when saved.
1104 Revision 400.63 2002/12/15 05:50:59 ajc
1105 * Form editing of date/time fields now assumes that the icaltimetype being
1106 manipulated is in UTC. It converts to/from local time for editing.
1108 Revision 400.62 2002/12/10 23:25:47 ajc
1109 * Display attendees in message view of calendar objects
1111 Revision 400.61 2002/12/07 22:12:59 ajc
1112 * Handle incoming RSVP's for meetings. (Note: this will not actually work
1113 until I implement the Citadel server function which it calls.)
1115 Revision 400.60 2002/11/30 21:34:51 ajc
1116 * Submit organizer in a hidden field, in case the server needs it
1118 Revision 400.59 2002/11/30 04:46:46 ajc
1119 * First cut at adding/removing attendees to an event
1120 (Actual invitations should be sent by the Citadel server)
1122 Revision 400.58 2002/11/29 23:56:19 ajc
1123 * Completed "me as organizer" -- the user's own e-mail address is inserted
1124 as the organizer of new events. Detect when the user is the organizer and
1125 enable/disable the attendees box accordingly.
1127 Revision 400.57 2002/11/29 16:38:37 ajc
1128 * Started some "me as organizer" stuff. (BROKEN BUILD ... I'll fix soon.)
1130 Revision 400.56 2002/11/28 06:03:24 ajc
1131 * Issue an ISME command when editing an event, to determine whether the user
1132 viewing the event is the organizer. (Will use this later to allow/disallow
1133 sending out invitations.)
1135 Revision 400.55 2002/11/26 05:01:04 ajc
1136 * Began handling attendee fields
1138 Revision 400.54 2002/11/16 23:40:11 ajc
1141 Revision 400.53 2002/11/16 23:15:02 ajc
1142 * Make the "all day event" shadebox smaller (month view) - no border.
1143 * Fixed bug that caused any events following an all day event to also appear
1146 Revision 400.52 2002/11/16 05:40:54 ajc
1147 * When adding new events to the calendar, default to the month [and day]
1148 currently being viewed.
1149 * Hotlink each hour of the day view to an add-new-event for that day/hour.
1151 Revision 400.51 2002/11/15 05:05:47 ajc
1152 * Put in back/forward (yesterday/tomorrow) links in calendar day view
1154 Revision 400.50 2002/11/15 04:11:46 ajc
1155 * Added even more nifty JavaScript to cause the hour/minute and end date
1156 fields of a calendar event form to render as disabled when the "all day
1157 event" box is checked -- not just when the user checks the box, but also
1158 when the box begins its life already checked.
1160 Revision 400.49 2002/11/14 04:59:40 ajc
1161 * Correctly serialize and save all day events using date instead of date/time
1163 Revision 400.48 2002/11/13 04:49:23 ajc
1164 * "All day event" shows as a single checkbox, instead of one for the start
1165 time and one for the end time. Added nifty JavaScript to zero and shade
1166 the hour/minute and all end time fields when all-day-event is checked.
1168 Revision 400.47 2002/11/12 05:57:27 ajc
1169 * Display a nicer looking screen when replying to calendar invitations
1170 * When displaying day view, don't show all day events twice
1171 * Day or month view: denote all day events by displaying them inside
1174 Revision 400.46 2002/11/12 03:26:39 ajc
1175 * Tell the user about broken Citadel server connections instead of
1176 simply printing "Goodbye"
1178 Revision 400.45 2002/10/23 04:11:38 ajc
1179 * Detect when a meeting invitation is actually an update for an existing UID
1180 and tell the user so.
1182 Revision 400.44 2002/10/21 20:16:38 ajc
1183 * Display conflicts nicely
1185 Revision 400.43 2002/10/21 18:29:14 ajc
1186 * Ask server to hunt for conflicts when displaying a meeting invitation
1188 Revision 400.42 2002/10/19 21:28:32 ajc
1189 * Moved the calendar meeting request reply functionality to the Citadel server

1202 * Fixes and updates to build WebCit on Linux for IBM S/390
1204 Revision 400.37 2002/10/09 04:12:44 ajc
1205 * Templatized trailing HTML
1206 * Templatized "new start page" page
1207 * Added global substitution macros
1209 Revision 400.36 2002/10/09 03:51:01 ajc
1210 * Templatized the <HEAD> section of HTML
1212 Revision 400.35 2002/10/07 23:03:38 ajc
1213 * messages.c: don't display room name field when it's blank
1215 Revision 400.34 2002/10/07 04:10:37 ajc
1216 * When displaying meeting invitations, only show date/time for VEVENT
1217 subcomponents. Date/time for other subcomponents are irrelevant.
1218 * Cleaned up HTML display of meeting invitations.
1220 Revision 400.33 2002/10/03 03:40:31 ajc
1221 * Worked on meeting accept/decline a little bit
1223 Revision 400.32 2002/09/30 03:58:35 ajc
1224 * Dabbled in handling incoming meeting requests
1226 Revision 400.31 2002/09/29 20:15:43 ajc
1227 * Completed the calendar day view
1229 Revision 400.30 2002/09/28 04:01:30 ajc
1230 * started fleshing out the calendar day view
1232 Revision 400.29 2002/09/27 21:19:28 ajc
1235 Revision 400.28 2002/09/27 18:31:33 ajc
1236 * Properly handle VEVENT saves (fixed nasty loopy loopy bug)
1237 * After saving a VEVENT, return to the correct calendar view and date
1239 Revision 400.27 2002/09/27 17:15:44 ajc
1240 * Removed the gzip compression stuff due to bugs in Internet Explorer.
1242 Revision 400.26 2002/09/27 04:37:21 ajc
1243 * New, buggy versions of event editing screens
1245 Revision 400.25 2002/09/26 22:00:16 ajc
1246 * Fixed buggy month-selection algorithm (January is month 0 in 'struct tm' but
1247 month 1 in libical functions)
1249 Revision 400.24 2002/09/25 21:57:13 ajc
1250 * Keep track of msgnums in the two-pass calendar loop, so we can hotlink to
1253 Revision 400.23 2002/09/24 04:12:34 ajc
1254 * Rough cut of the two-pass calendar display routines (first pass: go thru
1255 messages gathering VEVENT items; second pass: render calendar with data)
1257 Revision 400.22 2002/09/23 04:01:33 ajc
1258 * Presentation changes to calendar month view
1260 Revision 400.21 2002/09/22 05:20:27 ajc
1261 * Began implementing month view
1263 Revision 400.20 2002/09/21 04:38:05 ajc
1264 * Added utility functions for displaying vcalendar timestamps in web forms
1265 and translating form data back to timestamps.
1266 * Completed the "edit task" and "add new task" screens.
1268 Revision 400.19 2002/09/20 20:28:08 ajc
1269 * Smooth transition between "list tasks" & "edit task" screens
1271 Revision 400.18 2002/09/20 03:54:44 ajc
1272 * Display the "Tasks" view as a bulleted list with each task clickable
1273 * Clicking brings up an (unfinished) "edit task" screen
1275 Revision 400.17 2002/09/18 21:44:02 ajc
1276 * display VTODO parameters
1278 Revision 400.16 2002/09/17 04:21:00 ajc
1279 * Handler chains for VCALENDAR and VTODO types
1281 Revision 400.15 2002/09/17 03:37:10 ajc
1282 * Implemented a 'display handler' infrastructure for various groupware types
1284 Revision 400.14 2002/09/16 03:35:12 ajc
1285 * Just a bunch of glue code to iterate through the various types of ical
1286 objects we could encounter
1288 Revision 400.13 2002/09/15 04:05:41 ajc
1289 * Process calendar object subcomponents
1291 Revision 400.12 2002/09/15 03:40:13 ajc
1293 * When a text/calendar MIME type is discovered in a message, send it to
1294 the (currently skeleton) parser in calendar.c
1295 * calendar.c: skeleton parser for calendar objects which currently just
1296 creates an icalcomponent object and frees it.
1298 Revision 400.11 2002/09/15 03:16:24 ajc
1299 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
1300 function namespace in libical
1302 Revision 400.10 2002/09/15 02:50:55 ajc
1303 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
1305 Revision 400.9 2002/09/14 21:33:31 ajc
1306 * Backed out compression of inlines -- not all browsers appear to handle it
1308 Revision 400.8 2002/09/14 20:20:29 ajc
1309 * Attempting to push more stuff through compression. I've introduced some
1310 sort of deadlock bug that I can't seem to find yet...
1312 Revision 400.7 2002/09/14 20:00:22 ajc
1313 * Compress output_image() graphics
1315 Revision 400.6 2002/09/14 16:26:35 ajc
1316 * output_image() now reads the entire image from Citadel into a buffer before
1317 sending it to the browser (for performance reasons, and so it can compress)
1319 Revision 400.5 2002/09/14 04:52:59 ajc
1320 * Look for the "libical" calendaring library and link it in if present...
1322 Revision 400.4 2002/09/14 04:02:36 ajc
1323 * Finished gzip compression of dynamic pages (when browser supports it)
1325 Revision 400.3 2002/09/13 20:40:53 ajc
1326 * Detect when the client browser is capable of gzip encoding
1327 (actual encoding is not implemented yet)
1329 Revision 400.2 2002/09/13 15:54:40 ajc
1330 * Reversed the above change because I broke it somehow
1332 Revision 400.1 2002/09/11 22:46:59 ajc
1333 * Started adding in compression and calendaring library detects (not finished)
1335 Revision 400.0 2002/09/09 03:56:11 ajc
1336 * This is version 4.00
1338 Revision 323.68 2002/09/09 03:51:01 ajc
1339 * In the HTML-to-HTML converter:
1340 --> Open links in new window (as with text msgs)
1341 --> Convert loose URL's to hot links (as with text msgs)
1343 Revision 323.67 2002/09/06 03:59:11 ajc
1344 * Added an "About this server" panel to the Summary page.
1345 (Useless fluff, but better than an empty column.)
1347 Revision 323.66 2002/08/26 02:57:06 ajc
1348 * Rooms listed on the summary page are now clickable-gotoable
1350 Revision 323.65 2002/08/26 01:24:09 ajc
1351 * Added a "summary" page (rather sparse for now)
1353 Revision 323.64 2002/08/24 15:30:48 ajc
1354 * GET instead of POST for listsub. Also add a 'Back...' link.
1356 Revision 323.63 2002/08/24 05:59:24 ajc
1357 * Bugfixes and cosmetic changes to listsub system
1359 Revision 323.62 2002/08/23 03:37:19 ajc
1360 * Finished all of the subscribe/unsubscribe/confirm stuff! (I think)
1362 Revision 323.61 2002/08/22 03:55:47 ajc
1363 * 'unsubscribe' command (but not 'confirm unsubscribe')
1365 Revision 323.60 2002/08/21 21:58:37 ajc
1366 * Completed self-service list subscription via web.
1367 (Still need to implement unsubscribe.)

1692 queue length to 100 for use on big systems. Also, during startup, the
1693 initial startup thread now exits after creating the worker threads, instead
1694 of becoming a worker thread itself. For some reason Solaris had problems
1695 with the latter method.

1828 Revision 211.19 2000/05/18 02:33:39 ajc
1829 * Don't call whobbs() directly after changing masq room/host, it screws up the

1846 crashing every session, every time. (?)
1847 * End the session after displaying robots.txt or nocookies.html, to prevent
1848 big session logjams when either of these conditions are met
1850 Revision 211.14 2000/04/15 15:43:46 nbryant
1851 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

1939 * Finished the overhaul. Now to tune...
1941 Revision 1.111 1999/12/03 17:59:53 ajc
1942 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
1943 pseudocode so the build is currently broken.
1945 Revision 1.110 1999/12/03 16:37:46 ajc
1946 * Repaired HTTP output for image transfers and static content
1948 Revision 1.109 1999/12/03 05:09:54 ajc
1949 * Rewrote the HTTP engine and application coupling to run in a worker thread
1950 model and to run as a single multithreaded program (eliminated helper

1975 Revision 1.101 1999/10/06 02:44:02 ajc
1976 * Per Nick's request, removed the key bindings stuff. He knows how to fit
1977 it back in when it's fixed. Also added more attempts at cache disabling,
1978 but it still doesn't work in the StarOffice browser. I don't know why.
1980 Revision 1.100 1999/10/02 03:26:14 ajc
1981 * Merged in Nick's bit of JavaScript to handle key commands.
1982 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
1983 in a text field. Right now you can't even log in.
1985 Revision 1.99 1999/09/01 01:06:11 ajc

1997 to a Citadel server fails.
1998 * messages.c: don't auto-link URL's in messages if it would cause
2001 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2002 * Recompiled the Java chat applet using a genuine JDK 1.0.2

2037 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

2039 among other places, IE 5. Die, Bill, Die.
2041 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2042 * Fixed the behavior of the "forget room" routine, to properly handle
2043 the transition back to the Lobby after it's all done.
2044 * Added ExpressMessageCat() to allow code to send the user messages
2045 along with incoming express messages
2046 * WebCit now sends the name of the end user's browser as the client
2047 name in a Citadel IDEN command rather than its own name.
2049 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2050 * Minor code cleanups

2060 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2061 * Replaced _most_ gotoroom() calls with smart_goto(), a version

2075 * Changed the noframes mode to display "fake" frames using tables
2077 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nick@ulster.net>
2078 Changed some output formatting (mainly <FONT> tags).
2079 Changed who.c to use urlescputs() rather than escputs()
2080 in urls so GOTOs and User Profiles work when the string has a
2083 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2084 http://www.webreference.com/dhtml/column18/menuFrLoad.html
2085 How to cause "onLoad=" to cause a sibling frame to refresh without
2086 having to use the nonportable HTTP "Window-Target:" directive. Began
2087 implementation of this; it should allow portable NS/IE compatibility.
2089 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2090 * Implemented "access level required to create rooms"

2093 * webcit.c: modified getz() to *exit* the program when fgets()
2094 returns an error. This is actually the desired behavior; it would
2095 otherwise busy-loop forever on a broken pipe.
2097 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2098 * webcit.c: added to getz() the ability to return an error code;

2101 * Added HTTP "User-agent:" detection
2102 * wildmat.c, braindamage.c: added

2107 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
2108 * context_loop.c: warning fix
2109 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
2111 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2112 * Resolve the name of the connecting host and pass it on to Citadel
2114 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2115 * wDumpContent() is now responsible for </BODY></HTML> most of the
2116 time (parameter settable) so that the main menu can easily be
2117 embedded in every page when running in noframes mode
2118 * noframes mode selection is now carried in the cookie
2120 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2121 * Made the frames stuff less dependent on the HTML TARGET= directive
2122 and more dependent on the HTTP Window-target: directive.
2123 * Made the system semi-navigable in noframes mode.
2125 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2126 * Brought over the new room listing code and <G>oto heuristics
2127 from the main Citadel tree, to pay attention to floor/room ordering
2129 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2130 * Modified the back end of mime_parser to use callbacks instead of
2131 doing something specific. Now we can use it elsewhere.
2133 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2134 * Fixed the bugs in "Site-wide configuration"
2135 * Added a "generic server commands" screen
2137 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2138 * Reduced the multiple cookies down to one cookie combining all data.
2140 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

2145 * Added "enter registration"
2146 * Set up automatic trigger of Enter Registration when the server
2148 * Established that a one-to-one WebCit/Citadel correspondence will
2149 be required. No big deal due to shared code segments.
2150 * Added "change password"
2151 * Added networking configuration screens. These still need testing.
2152 * Added a "kill session" link to each line of the wholist when
2153 logged in as an aide, and the screens to perform this operation.
2155 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2156 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).

2165 * Wrote mime_parser.c for handling of image uploads. This will also
2166 be used in future Citadel MIME projects.

2177 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2178 * Changed the "auto read new" functionality from a meta refresh tag
2179 to an "onload" directive (the former was causing graphics problems)
2180 * Added "create room"

2192 * Added goto private rooms
2194 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2195 * Replace "Citadel" in menu bar with the Citadel logo
2197 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>

2201 * context_loop.c: Moved "remove session" into its own function.
2202 Check for dead webcit child process before each transaction.

2222 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2223 * context_loop.c: After fork(), child process closes the HTTP socket
2224 so when the parent process closes it, it actually _does_ close.
2225 Otherwise, aIEeeee and possibly other browsers will hang.
2226 * Added support for graphics images retrieved from the Citadel server.
