2 Revision 619.24 2005/07/14 04:21:53 ajc
3 * More intelligent JavaScript to handle the greying out of end date and
4 start/end times when "all day event" is selected.
6 Revision 619.23 2005/07/14 04:02:18 ajc
7 * Fix bug #147 (date sometimes saved incorrectly for all day events due
8 to timezone differences)
10 Revision 619.22 2005/07/13 16:55:59 ajc
11 * Use the new icons in more places.
13 Revision 619.21 2005/07/13 01:59:20 ajc
14 * Installed the final batch of new icons
16 Revision 619.20 2005/07/12 22:10:52 ajc
19 Revision 619.19 2005/06/29 17:55:32 ajc
20 * Any HTTP method other than GET or POST is now routed directly to the
21 GroupDAV code. This will eventually allow requests such as "PROPFIND /"
23 * GroupDAV requests not beginning with "/groupdav" now automatically have
24 that prefix prepended to them.
26 Revision 619.18 2005/06/29 15:25:00 ajc
27 * Added an experimental OPTIONS method. This is not required by GroupDAV,
28 but it is an experiment to see whether we can use the same code framework
29 to implement other DAV variants in the future.
31 Revision 619.17 2005/06/29 03:12:28 ajc
32 * Bumped internal version number to 6.20
34 Revision 619.16 2005/06/29 03:10:10 ajc
35 * PROPFIND on an individual item inside a room now works (it simply
36 spews the href and etag properties, regardless of what the request
37 was). This is not valid GroupDAV, but Kontact expects this request to
38 succeed before an item can be deleted, so we provide a simple response.
40 Revision 619.15 2005/06/28 14:12:38 ajc
41 * GroupDAV HTTP header "ETag:" is now output as "etag:" in order to deal with
42 a case-sensitivity bug in the Kontact client.
44 Revision 619.14 2005/06/27 22:15:38 ajc
45 * Header file adjustments to make it work on FreeBSD
47 Revision 619.13 2005/06/27 17:38:06 ajc
48 * HTML pages are now output as "Content-type: text/html; charset=utf-8"
49 UTF-8 is going to be the standard character set for the Citadel system.
51 Revision 619.12 2005/06/24 19:58:02 ajc
52 * Added a "preferences and settings" screen for each user.
53 * Removed the javascript date output stuff because it's not granular
54 or international enough.
55 * All dates and times can now be 12 or 24 hours.
57 Revision 619.11 2005/06/24 15:17:48 ajc
58 * The date/time stamp of messages are now output using JavaScript's
59 toLocaleString() function, observing the browser's locale and timezone
60 instead of the web server's.
62 Revision 619.10 2005/06/23 04:01:59 ajc
63 * groupdav_main.c: remove double slashes in path name
64 (suggested by Johannes Schneider)
66 Revision 619.9 2005/06/22 03:04:22 ajc
67 * siteconfig.c: add "auto db log cull" setting now in Citadel 6.52
69 Revision 619.8 2005/06/21 02:27:37 ajc
70 * Moved some JavaScript functions out of head.html and into a new wclib.js
71 file, which can be included and cached. This will form the basis for a
72 new WebCit JavaScript function library.
74 Revision 619.7 2005/06/20 20:38:50 ajc
75 * The main stylesheet is now in a separate file in the static/ directory.
76 Something we did recently must have fixed the caching problem, because it's
77 only being fetched once now (or "now once" if you're Pennsylvania Dutch).
79 Revision 619.6 2005/06/20 03:47:44 ajc
80 * inetconf.c: in save_inetconf(), eliminate sizeof(x) where x is a pointer
81 to a heap-allocated buffer rather than a char[xxx]. This fixes a problem
82 reported by at least one site where the Internet configuration screen
85 Revision 619.5 2005/06/19 04:11:52 ajc
86 * Integrated the second batch of new icons.
88 Revision 619.4 2005/06/18 22:58:56 ajc
89 * Installed the 16x16 "users" icon as favicon.ico, mainly for performance
90 reasons -- the browser will cache favicon.ico and won't keep asking for
91 it over and over again, eliminating a second HTTP transaction every time
92 the user clicks on something.
94 Revision 619.3 2005/06/18 22:48:32 ajc
95 *** empty log message ***
97 Revision 619.2 2005/06/18 22:18:29 ajc
98 * Replaced the most recent batch of icons with a "better" set which was
99 sent by the design house. I don't know what the difference is, but
100 I'm going to assume they're better.
102 Revision 619.1 2005/06/15 03:56:56 ajc
103 * Accept ".ifb" as a valid extension for requesting free/busy
105 Revision 619.0 2005/06/15 01:52:33 ajc
108 Revision 611.15 2005/06/15 01:50:29 ajc
109 * Bumped the internal version number to 6.19
111 Revision 611.14 2005/06/14 14:47:48 ajc
112 * Moved the <td> and </td> in the room icon out of roomops.c and
113 into static/roombanner.html, since every room will have an icon now.
115 Revision 611.13 2005/06/14 03:21:57 ajc
116 * When no icon is present on the server for a room, display the default
117 icon for that room's current view.
118 * Replace "graphic" with "icon" throughout the system messages.
120 Revision 611.12 2005/06/14 01:59:43 ajc
121 * 16x16 icons in the new tree view. Nice!
123 Revision 611.11 2005/06/13 22:05:54 ajc
124 * Finished the initial NanoTree integration. TODO: use a different icon
125 for each node depending on the view set for that room.
127 Revision 611.10 2005/06/12 22:02:45 ajc
128 * Began replacing the old, sux0r-prone tree view with NanoTree.
129 WARNING: This isn't finished, but I'm committing it anyway because I have
130 to move to a different computer. DON'T RUN THIS.
132 Revision 611.9 2005/06/12 18:34:50 ajc
133 * Removed some unreferenced files from the static/ directory.
135 Revision 611.8 2005/06/12 17:01:00 ajc
136 * Increase maximum viewable message count from 4096 to 10000
137 * Summary view now truncates subject to 75 characters, and sender
138 to 25 characters (adding an ellipsis...) to keep the display neat & tidy
140 Revision 611.7 2005/06/12 16:03:11 ajc
141 * When viewing a mailbox (view == VIEW_MAILBOX), messages are marked as
142 seen when they are viewed, and Goto does not automatically mark the
143 remaining messages as seen.
145 Revision 611.6 2005/06/11 22:29:07 ajc
146 * Integrated the first batch of new icons.
148 Revision 611.5 2005/06/07 04:31:00 ajc
149 * Don't compress when HTTP tracing/logging is enabled
151 Revision 611.4 2005/06/06 23:50:17 ajc
152 * Made some changes to the calendar/uuid logic to fix a bug that caused
153 duplicate entries for an event to appear in some situations
155 Revision 611.3 2005/06/06 16:20:36 ajc
156 * GroupDAV URI escape character is now '%' in order to be consistent...
158 Revision 611.2 2005/06/04 04:07:36 ajc
159 * Calendar invitations: changed "Accept/Tentative/Decline" buttons to
160 links in order to avoid them being in nested forms.
162 Revision 611.1 2005/06/02 16:10:08 ajc
163 * tools.c: generated uuid's no longer contain "{" and "}" characters.
165 Revision 611.0 2005/05/26 04:38:09 ajc
168 Revision 610.9 2005/05/26 04:37:59 ajc
169 * Updated internal version number to 6.11
171 Revision 610.8 2005/05/26 04:28:27 ajc
172 * Applied GroupDAV patches sent in by Johannes Schneider which improve the
173 protocol accuracy of xmlns and etag responses.
174 * Fixed a MIME Content-Type bug which I had inadvertently introduced while
175 removing a temporary hack that was put in during KDE 3.4 beta
177 Revision 610.7 2005/05/24 04:26:47 ajc
178 * Applied a patch sent by Johannes Schneider for correcting the XML
179 namespace presented in the PROPFIND command.
181 Revision 610.6 2005/05/23 19:30:34 ajc
182 * Move "enable full text" checkbox configuration to its new location in
183 the configuration back end.
185 Revision 610.5 2005/05/22 16:20:09 ajc
186 * siteconfig.c: add checkbox for enabling full text index on server
188 Revision 610.4 2005/05/11 03:00:03 ajc
189 * webcit.c: fixed a string bug that caused the whole system to not work
190 * messages.c: fullname only and brief date in summary view, so that it
191 doesn't wrap onto two lines quite as often
193 Revision 610.3 2005/04/11 20:09:33 ajc
194 * Began an assault on strcpy()
196 Revision 610.2 2005/04/11 14:45:12 ajc
197 * Replaced serv_gets() with serv_getln() - which now requires the caller
198 to supply the size of the target buffer.
200 Revision 610.1 2005/04/08 19:36:56 ajc
201 * Moved to the new string tokenizer API
203 Revision 610.0 2005/04/04 17:50:04 ajc
204 * THIS IS 6.10 (unfinished first time install wizard has been disabled)
206 Revision 603.15 2005/04/04 17:49:31 ajc
207 * configure.in: fix libical version detection
208 * bumped internal version number to 6.10
210 Revision 603.14 2005/03/30 21:44:44 ajc
211 * Changed the color of the side button bar
212 * Removed session ID's from wholist display, because they are only
213 interesting to computers, not to people.
214 * Also changed the session ID variable (we still need it internally) from
215 a char to an int, because session numbers are big now.
217 Revision 603.13 2005/03/30 17:27:55 ajc
218 * serv_crypto.c: made changes to OpenSSL calls ... removed unnecessary
219 calls and also enabled SSLv3/TLSv1
221 Revision 603.12 2005/03/10 05:13:21 ajc
222 * Created the framework for the "first time setup wizard"
224 Revision 603.11 2005/03/09 04:08:30 ajc
225 * Delete room is now confirmed through a JavaScript popup instead of
227 * New icon for "Tasks." In order to keep it consistent with the rest of
228 the icons, it is ugly.
229 * Modified page popup style slightly.
231 Revision 603.10 2005/03/08 04:59:31 ajc
232 * More attractive display of vCards (hide unknown fields)
233 * Added "title" and "organization" to vCard display/edit
234 * Replaced semicolon with comma-space in vCard name display
236 Revision 603.9 2005/03/07 04:03:28 ajc
237 * auth.c: shrink the margins on the login screen so the user sees something
239 * Allow editing of address book entries wherever possible.
240 * Anything that was a (link) is now a [link]
242 Revision 603.8 2005/03/07 01:45:30 ajc
243 * Rolled back to the old RTE because the new one doesn't work in Safari.
245 Revision 603.7 2005/03/05 22:26:26 ajc
246 * crypto.c: allow use of chained certificates
248 Revision 603.6 2005/03/05 05:04:34 ajc
251 Revision 603.5 2005/03/04 04:21:05 ajc
252 * When a room is set to the "mailbox" view, "Read new / read all" is
253 replaced by "View message list."
255 Revision 603.4 2005/02/28 04:01:55 ajc
256 * Updated to the latest version of Kevin Roth's richtext editor. Had to
257 modify it a bit (removal of 'px' suffix, and addition of 'cols=80') to
258 allow it to gracefully degrade in Konqueror even when we specify our
260 * Modified the message entry screen a bit. Full height just isn't practical
261 with all those wacky browsers out there, unfortunately. Removed most of
264 Revision 603.3 2005/02/23 05:08:20 ajc
265 * Better control of HTTP headers which control browser caches. Static
266 objects are getting properly cached now.
268 Revision 603.2 2005/02/22 05:15:28 ajc
269 * When the "begin_burst() / end_burst()" semantics are in use, perform
270 gzip compression when the client indicates support for it.
272 Revision 603.1 2005/02/21 23:00:04 ajc
273 * begin_burst() / end_burst() semantics now apply to all pages which are
274 output using the "include_html_head" option of output_headers() (which
275 is nearly all of them). This should speed up the network considerably,
276 and also pave the way for another attempt at adding zlib compression
279 Revision 603.0 2005/02/21 22:00:13 ajc
282 Revision 602.10 2005/02/21 21:57:55 ajc
283 * Various debugging type of everythingism to help chat mode to work.
285 Revision 602.9 2005/02/21 04:47:41 ajc
286 * When creating rooms:
287 * 1. Selecting a view other than "Bulletin Board" causes the room access
288 * type to default to "private mailbox"
289 * 2. When the room access type changes to "private mailbox," the floor
290 * selector is greyed out because it is irrelevant.
292 Revision 602.8 2005/02/20 06:48:30 ajc
293 * View-o-matic now has "View as: " before it. "Messages" has been changed
294 to "Bulletin Board" and "Summary" has been changed to "Mailbox Summary"
295 * The View-o-matic is now styled to be smaller and color-matched to the
296 banner box it lives in.
297 * Removed "Summary" from message range selector. It is redundant.
299 Revision 602.7 2005/02/20 06:27:53 ajc
300 * Switched the Reply/Move/Delete buttons back to ordinary links, because
301 the nested forms were causing the bottom part of the outer form to stop
302 working (message range selector went dead). Thanks to triLcat for
305 Revision 602.6 2005/02/19 06:01:14 ajc
306 * The previous <div style=\"margin-right:1px\"> has been replaced by a
307 named div in the stylesheet. This allows us to perform a vile, sleazy
308 hack to keep IE6 from exhibiting its horizontal scrollbar bug. There
309 will unfortunately always be a right margin in IE6, but there
310 doesn't appear to be any easy workaround.
312 Revision 602.5 2005/02/19 05:22:00 ajc
313 * Replaced all the "centered 99% tables" with 100% width tables wrapped
314 inside a div with margin-right:1px to remove the horizontal scrollbar
315 in Gecko without creating whitespace. IE6's problem is much more
316 serious and will require dropping a nuclear bomb on Redmond to fix.
318 Revision 602.4 2005/02/18 05:09:52 ajc
319 * Moved the room access control screen into a tab on the edit room menu
321 Revision 602.3 2005/02/17 04:48:26 ajc
322 * After setup is complete, tell them how to log in.
323 * Don't allow the creation of accounts with blank passwords.
324 * Don't allow users to change to a blank password.
325 * Fixed the positioning of a few more screens that accidentally got
326 partially hidden underneath the iconbar.
327 * Boldfaced the "Password changed." and other prompts.
328 * Removed the unreadable blue-on-blue links in the calendar day
329 view. They're redundant anyway, now: "Add new calendar event" and
330 "month view" are both in the banner bar.
331 * "New messages / All messages" are now "Read new messages / Read all
333 * "Save message" button is now "Post message" for public room posts,
334 and "Send message" for email.
335 * "Message has been posted" is now "Message has been sent" for email.
336 * Swapped positions of "Add users" and "Edit users" boxes.
337 * vCard editor: "Other Internet email addresses" is now "aliases"
338 * Renamed the "Users" button to "Who is online?"
340 Revision 602.2 2005/02/16 05:40:31 ajc
343 Revision 602.1 2005/02/16 05:22:22 ajc
344 * inetconf.c: fixed memory management problem that was causing all
345 the inetconf to get discarded during edit on IBM POWER5
347 Revision 602.0 2005/02/15 05:23:10 ajc
350 Revision 601.3 2005/02/15 05:20:44 ajc
351 * Fixed an HTTP output error for static data which was causing images
352 to display improperly in Konqueror
353 * Changed most of the beginbox_nt boxes to centered tables with 99%
354 width, to avoid the mysterious horizontal scrollbar
356 Revision 601.2 2005/02/14 04:57:23 ajc
357 * Started changing some of the top-level tables from 100% width to 99%
358 width in order to keep the b0rken CSS box-model from displaying a
359 horizontal scroll bar when it shouldn't. Lose, lose, lose.
361 Revision 601.1 2005/02/13 04:22:31 ajc
362 * Network configuration screen: add IMAPS, POP3S, and SMTPS ports
364 Revision 601.0 2005/02/12 04:23:43 ajc
367 Revision 528.48 2005/02/11 03:35:57 ajc
368 * useredit.c: added an "Delete user" button, because it was unintuitive
369 to tell people "Delete a user by setting their access level to 0"
371 Revision 528.47 2005/02/09 04:37:32 ajc
372 * More GroupDAV fixes and tuning.
374 Revision 528.46 2005/02/07 22:02:00 ajc
375 * groupdav_propfind.c: output all XML on a single line, with no linebreaks,
376 and no whitespace between tags. We have discovered that doing otherwise
377 will break certain clients.
379 Revision 528.45 2005/02/06 03:59:33 ajc
380 * Added some HTTP Date: header output
382 Revision 528.44 2005/02/05 22:58:46 ajc
383 * All GroupDAV HTTP output is now \r\n instead of \n terminated.
385 Revision 528.43 2005/02/05 08:36:13 ajc
386 * Added an everything-buffering thingi so we can do Content-length:
388 Revision 528.42 2005/02/05 04:16:01 ajc
389 * Cleanup of new message range view-o-matic
390 * GroupDAV GET operations now only send the Content-type: and Date:
391 headers. All the others are irrelevant.
393 Revision 528.41 2005/02/04 19:19:23 ajc
394 * Message reading range selection is now a drop-down box.
396 Revision 528.40 2005/02/04 17:22:18 ajc
397 * Cleaned up the rcs/cvs Id tags and leading comments at the top of some files
399 Revision 528.39 2005/02/04 03:43:31 ajc
400 * fixed the tasks view in the summary screen
402 Revision 528.38 2005/02/03 05:13:57 ajc
403 * More tuning for GroupDAV compliance.
405 Revision 528.37 2005/02/03 04:38:40 ajc
406 * VTODO components need to be encapsulated inside VCALENDAR components,
407 just like we do with VEVENT components. There's a bunch of software
408 (including the beforesave hook on our own Citadel server) that expects
411 Revision 528.36 2005/02/02 23:25:21 ajc
412 * Encode GroupDAV uid's using more concise string escaping, because the
413 old way was making KOrganizer choke.
415 Revision 528.35 2005/02/02 04:13:36 ajc
416 * Debugged the GroupDAV service with KOrganizer. It's mostly working now.
418 Revision 528.34 2005/02/01 23:15:50 ajc
419 * Completed GroupDAV PUT. Untested.
421 Revision 528.33 2005/02/01 19:52:29 ajc
422 * Bumped the internal version number to 6.01
423 * Set the minimum required Citadel version to 6.40, because we need the
424 automatic fill-in-missing-uid groupware stuff, and the new ENT0 semantics
427 Revision 528.32 2005/02/01 15:15:40 ajc
428 * Better purging of not-logged-in GroupDAV sessions
430 Revision 528.31 2005/02/01 14:55:12 ajc
431 * Reworked the PROPFIND xml output based on an example transaction
432 supplied by Reinhold Kainhofer. Groupware folder enumeration works
433 properly in Kontact now.
435 Revision 528.30 2005/02/01 03:49:09 ajc
436 * Completed "folder list" PROPFIND, now listing all rooms set to a
437 calendar, tasks, or address view, using the GroupDAV properties.
439 Revision 528.29 2005/02/01 02:28:32 ajc
440 * "time(NULL) mod 60" doesn't work for some reason, so it has been removed.
441 When defaulting a new event date/time to now, set the seconds to zero
444 Revision 528.28 2005/01/31 23:31:26 ajc
445 * Initial attempt at GroupDAV PROPFIND for folder enumeration. Hardcoded
446 to only show the Calendar> room. It kinda-sorta works with KOrganizer.
448 Revision 528.27 2005/01/31 16:24:47 ajc
449 * iconbar is now a happy css hovery lightupy div thing
451 Revision 528.26 2005/01/29 03:59:25 ajc
452 * Implemented the GroupDAV DELETE method.
454 Revision 528.25 2005/01/28 05:25:43 ajc
455 * iconbar no longer uses the beginbox/endbox semantics, but instead lives
456 directly inside the iconbar div.
458 Revision 528.24 2005/01/28 05:13:02 ajc
459 * GroupDAV object URL's are now based on the EUID of a message (which is
460 derived from the UID of the groupware object itself) instead of the
461 message number. This was done in order to conform to GroupDAV's
462 requirement that the URL cannot change after an object is updated.
463 * The ETag of a GroupDAV object is still the message number, and in fact
464 doing so meets that requirement perfectly.
466 Revision 528.23 2005/01/26 18:15:34 ajc
467 * PROPFIND now outputs fully qualified URL's
469 Revision 528.22 2005/01/26 18:02:22 ajc
470 * Initial implementation of GroupDAV PROPFIND
472 Revision 528.21 2005/01/26 16:28:23 ajc
473 * Output ETags in double quotes to conform with the new GroupDAV draft.
474 * Output HTTP Server: header in GroupDAV transactions
475 * Server: header now displays both WebCit and Citadel versions
476 * Added groupdav_common_headers() to output HTTP headers common to all
477 GroupDAV transactions (Connection: close, Server: WebCit, etc.)
479 Revision 528.20 2005/01/25 19:51:04 ajc
480 * Accept escaped characters in GroupDAV GET URL's
482 Revision 528.19 2005/01/25 04:17:20 ajc
483 * Implemented the Groupdav GET method, more or less in its final form
484 (still need to fix the room/folder naming semantics)
486 Revision 528.18 2005/01/25 03:12:27 ajc
487 * Completed HTTP "Basic" authentication, and a stub function for the
488 main entry point for GroupDAV functions.
490 Revision 528.17 2005/01/24 03:37:48 ajc
491 * Began laying the groundwork for http-authenticated GroupDAV sessions.
493 Revision 528.16 2005/01/22 22:50:51 ajc
494 * removed descriptions in non-main menus
496 Revision 528.15 2005/01/20 21:24:27 ajc
497 * When viewing a calendar room, the "Read all messages" link in the
498 room banner has been replaced by "Day view" and "Month view" links.
499 (I have also imported icons for week and year views, in case we add
502 Revision 528.14 2005/01/20 16:13:56 ajc
503 * Added in a bunch of stupid JavaScript to allow the instant message
504 window to be dismissed.
506 Revision 528.13 2005/01/20 04:10:41 ajc
507 * Cleaned up a bunch of unused cruft from the old layout
508 * Instant messages are now displayed in a div that layers itself
509 over the rest of the site. It would be nice if we could figure out
510 a way to make a clickable "hide" box...
512 Revision 528.12 2005/01/17 04:38:14 ajc
513 * Navbar is now dynamic, in an attempt to make only the relevant controls
514 appear on any given page.
516 Revision 528.11 2005/01/15 07:19:08 ajc
517 * Removed the fixed pixel width from the tree view room list so it doesn't
518 wrap around in an ugly way on aIEeeee.
520 Revision 528.10 2005/01/15 05:26:27 ajc
521 * Message entry window is now somewhat full screen.
523 Revision 528.9 2005/01/14 21:03:17 ajc
524 * A few logging hacks
526 Revision 528.8 2005/01/14 15:00:51 ajc
527 * Placed the navbar into the room banner, at least in its temporary form.
529 Revision 528.7 2005/01/14 04:53:54 ajc
530 *** empty log message ***
532 Revision 528.6 2005/01/14 04:53:12 ajc
533 * Got the three-pane model working not only with web browsers, but also
534 with the disgusting abomination called Internet Explorer.
536 Revision 528.5 2005/01/13 18:38:08 ajc
537 * Insert a newline between </div> and <div id="text">
539 Revision 528.4 2005/01/11 16:20:18 ajc
540 * Switching doctype from XHTML to HTML 4.01 STRICT, because nothing handles
543 Revision 528.3 2005/01/11 05:05:08 ajc
544 * *** HUGE CHANGES *** *** WARNING: NOT FULLY FUNCTIONAL ***
545 * Ripped things apart in a big way. The frameset is gone (except for
546 chat, for which we'll probably keep frames). Iconbar and banner are
547 now done using CSS and <div> tags.
548 * Room read/enter/goto controls are currently missing. Stay tuned.
549 * I am in the process of rewriting all of the markup as valid XHTML.
551 Revision 528.2 2004/12/29 22:08:08 ajc
552 * roomops.c: provide a way to create room shares with a mapping to an
553 alternate room name on the other end.
555 Revision 528.1 2004/12/29 17:28:09 ajc
556 * roomops.c: when adding/removing nodes in the 'Sharing' tab, don't go
557 all corrupty-whatever when a remote room name mapping is found. Display
558 the mapping and preserve it across share/unshare operations.
560 Revision 528.0 2004/12/28 03:58:34 ajc
563 Revision 527.1 2004/12/28 03:58:24 ajc
564 * Corrected overly-escaped reply-to addresses in "reply" button
565 * Repaired toggling of self-service account creation in admin screen
566 * Bumped internal version number to 5.28
568 Revision 527.0 2004/12/07 04:41:37 ajc
571 Revision 526.1 2004/12/07 04:41:02 ajc
572 * Finally tracked down the WC->vars heap corruption issue (for real this
573 time). We now call clear_local_substs() at the end of each HTTP
574 transaction, whether we need to or not, instead of calling it whenever
575 we're done with something we wanted session variables for.
576 * Finally tracked down the years-long "misplaced '(edit)' link" bug, by
577 copying serv_info->serv_pid to WC->ctdl_pid at the time it's loaded,
578 preventing it from getting clobbered by another session.
579 * Bumped internal version number to 5.27
581 Revision 526.0 2004/12/01 21:35:56 ajc
584 Revision 525.4 2004/12/01 21:35:44 ajc
585 * Changed internal version number to 5.26
587 Revision 525.3 2004/12/01 21:34:17 ajc
588 * Numerous memory management bugfixes.
590 Revision 525.2 2004/12/01 16:48:24 ajc
591 * tools.c: don't crash when striplt() is called with a zero-length string
593 Revision 525.1 2004/11/12 18:02:36 ajc
594 * Updated the richtext editor (new version from Kevin Roth's site)
596 Revision 525.0 2004/11/03 20:21:10 ajc
599 Revision 524.7 2004/11/03 20:21:02 ajc
600 * Changed internal version number to 5.25
602 Revision 524.6 2004/10/20 02:41:41 ajc
604 * Added the notes room to the icon bar
605 * Set up an initial implementation of Notes view. Attractive enough to
606 publish, but read-only. Needs a note editor.
608 Revision 524.5 2004/10/15 03:10:24 ajc
609 * Calendar objects UID now generated by generate_uuid() which creates
610 pseudo-DCE-ish UUID's.
612 Revision 524.4 2004/10/05 01:59:31 ajc
613 * localtime_r() fixes
615 Revision 524.3 2004/10/03 02:56:35 ajc
616 * Added a pthread_attr_destroy() in the appropriate place (thanks fleeb!)
618 Revision 524.2 2004/10/01 16:23:23 ajc
619 * Set up framework for "notes" view, and added a skeleton function for
622 Revision 524.1 2004/09/30 03:44:01 ajc
623 * fix line width break problem in chat
625 Revision 524.0 2004/09/28 16:12:44 ajc
628 Revision 523.12 2004/09/28 16:12:30 ajc
629 * Prepare for 5.24 release
631 Revision 523.11 2004/09/27 02:17:47 ajc
632 * messages.c: fix build problem on non-calendar-enabled installations
633 * floors.c: fix a warning message
635 Revision 523.10 2004/09/25 03:34:21 ajc
636 * summary.c: Fixed a calling syntax problem
638 Revision 523.9 2004/09/25 03:18:43 ajc
639 * small stylesheet fix
641 Revision 523.8 2004/09/24 04:21:41 ajc
642 * Fixed display bug for room list mode when we dropped down multiple
643 sublevels at once (such as, from 3 to 1 instead of from 2 to 1)
645 Revision 523.7 2004/09/24 04:08:25 ajc
646 * Put our <SPAN> tags back in to denote floors, rooms with new msgs, and
647 rooms without new msgs
649 Revision 523.6 2004/09/24 04:04:34 ajc
650 * "folders view" of room list now uses Dave Lindquist's "menuExpandable3"
653 Revision 523.5 2004/09/23 03:21:10 ajc
654 * roomops.c: "folders" view of rooms is an actual Unnumbered List now.
656 Revision 523.4 2004/09/16 02:42:37 ajc
657 * Set default view of new rooms during CRE8 command instead of afterwards
659 Revision 523.3 2004/09/15 03:08:50 ajc
660 * Support config of seaperate MSA port in Citadel 6.26
662 Revision 523.2 2004/09/10 03:49:17 ajc
663 * Added 'dialog' mode to setup
665 Revision 523.1 2004/08/31 20:31:01 ajc
666 * When saving VTODO (tasks), insert a UID if none is already present. Also
667 increment the sequence, or insert one if none is already present.
669 Revision 523.0 2004/08/31 03:02:37 ajc
672 Revision 522.30 2004/08/31 03:02:28 ajc
673 * Changed internal version number to 5.23
675 Revision 522.29 2004/08/27 02:40:06 ajc
676 * Ditched the graphical buttons because CSS can do the same thing faster.
678 Revision 522.28 2004/08/18 03:16:12 ajc
679 * 'move' and 'delete' buttons only show when allowed to do those things
681 Revision 522.27 2004/08/18 02:10:17 ajc
682 * Reply/Move/Delete buttons are now images, because system-native buttons
683 were too big and ugly.
685 Revision 522.26 2004/08/11 17:24:57 ajc
686 * static/iconbar.html: removed.
687 * Updated the "powered by citadel" graphic
689 Revision 522.25 2004/08/11 03:49:15 ajc
690 * Replaced all instances of the name "Citadel/UX" with "Citadel"
691 * Installed the "simple logo" in the iconbar
693 Revision 522.24 2004/08/09 03:11:20 ajc
694 * Changed DOCTYPE to HTML 3.2 because that's really what it resembles
696 Revision 522.23 2004/08/05 21:32:17 ajc
697 * Reply/Move/Delete are now buttons instead of links. This should enable
698 us to add some JavaScript magic for "Reply quoted" ...
700 Revision 522.22 2004/08/05 02:47:21 ajc
701 * Removed the "pull_quote" style and used the <BLOCKQUOTE> tag instead. It
702 has a more predictable and attractive behavior, and can still be
703 overridden in the style sheet if the site operator wants to.
705 Revision 522.21 2004/08/04 03:52:23 ajc
706 * Tasks view is now pretty.
707 * Tasks view now displays date due for each task.
708 * Tasks view is now sorted by date due.
709 * Tasks view now displays overdue tasks in red.
711 Revision 522.20 2004/08/03 03:55:37 ajc
712 * Tasks view now uses the same buffer/dump logic as the calendar views, so
713 we can sort them by due date and do a prettier display. (Only the logic is
714 changed so far. The prettier display is forthcoming.)
716 Revision 522.19 2004/07/21 02:57:09 ajc
717 * Internet Configuration screen looks a little neater now
719 Revision 522.18 2004/07/21 02:45:15 ajc
720 * Completed the "Internet Configuration" screen
722 Revision 522.17 2004/07/16 19:13:37 ajc
723 *** empty log message ***
725 Revision 522.16 2004/07/16 19:13:10 ajc
726 * tools.c: display 12:00 as 12pm, not 12am
728 Revision 522.15 2004/07/16 03:14:03 ajc
729 * more work on inetconf screen
731 Revision 522.14 2004/07/16 02:50:00 ajc
732 * useredit.c: put a pretty box around user editing
734 Revision 522.13 2004/07/13 03:25:08 ajc
735 * inetconf.c: added. Not finished yet.
737 Revision 522.12 2004/07/10 03:10:19 ajc
738 * Completed web screens for THE DREADED AUTO-PURGER by adding room and
739 floor level configurations.
740 * Put a space between OK and CANCEL buttons anywhere in the system where
742 * Some more of the room config/admin screens now return to themselves
743 with a "ok, you did that" message when OK is pressed, instead of dropping
744 out to the main menu.
746 Revision 522.11 2004/07/08 03:03:01 ajc
747 * Added global settings for THE DREADED AUTO-PURGER to the site-wide
748 configuration (public rooms default and mailboxes default). Still need
749 to add floor and room policy screens.
751 Revision 522.10 2004/07/02 03:28:08 ajc
752 * Much-improved alphabet tabs for Address Book view. Now divides the
753 total number of names by (names per page, currently 60) and sets up
754 that many tabs, with proper [Aaa-Bbb] labels on them.
756 Revision 522.9 2004/07/02 03:26:06 ajc
757 *** empty log message ***
759 Revision 522.8 2004/07/01 02:40:40 ajc
760 * Clicking "Enter a message" in a groupware room now automatically calls
761 the correct editor for the type of objects in the room (message, calendar
762 event, task, address book entry)
764 Revision 522.7 2004/06/29 17:21:25 ajc
765 * Removed the word "room" in a few locations, as part of our push towards
766 not looking like a BBS when running in groupware mode
768 Revision 522.6 2004/06/29 00:37:02 ajc
769 * Made some fonts bigger because users were complaining...
771 Revision 522.5 2004/06/27 03:02:05 ajc
772 * Summary view -- always view ALL messages
773 * Summary view -- new messages are in boldface
775 Revision 522.4 2004/06/24 20:42:14 ajc
776 * Added the "server ip address" Citadel config option
777 * Site config: added "Changes will not take effect until..." language
780 Revision 522.3 2004/06/24 14:50:35 ajc
781 * Added the ability to listen on a single IP address instead of all addresses.
783 Revision 522.2 2004/06/22 02:21:56 ajc
786 Revision 522.1 2004/06/21 15:00:52 ajc
789 Revision 522.0 2004/06/19 03:21:35 ajc
792 Revision 521.10 2004/06/19 03:11:07 ajc
793 * Instead of a crufty "the topmost Internet email address will be used
794 for outgoing email" explanation, separated it into "Primary Internet
795 email address" and "Other email addresses" boxes.
797 Revision 521.9 2004/06/19 02:42:12 ajc
798 * Removed the "aides access to mailboxes" config option, which is no longer
799 part of the Citadel system.
801 Revision 521.8 2004/06/16 02:07:22 ajc
802 * Removed a couple of lines of debugging code leftover from last night
804 Revision 521.7 2004/06/15 03:06:11 ajc
805 * Bumped internal version number to 5.22
806 * Use new fast headers-only-no-mime fetch mode in Citadel for
809 Revision 521.6 2004/06/15 02:30:21 ajc
810 * Honor "maxmsgs" even when viewing a mailbox in summary mode
812 Revision 521.5 2004/06/12 04:26:38 ajc
813 * Fixed some garbled output resulting from turning things that look like
816 Revision 521.4 2004/06/11 16:09:36 ajc
817 * Moved the room graphic to the left of the room name in the banner, to
818 make it more consistent with the rest of the site.
819 * Reduced the size of the font in the iconbar
821 Revision 521.3 2004/06/11 03:15:08 ajc
822 * When "Add" is clicked without specifying an upload filename, resume
823 composition instead of aborting the post.
824 * Add attachments to messages in forward order, not reverse order
826 Revision 521.2 2004/06/10 03:08:48 ajc
827 * Improved the appearance of tabs in the room config screen
829 Revision 521.1 2004/06/10 02:58:55 ajc
830 * Made all the title boxes the same background color. The old scheme was
831 cute but not professional looking.
833 Revision 521.0 2004/06/06 19:53:25 ajc
836 Revision 510.15 2004/06/06 19:32:15 ajc
837 * Cleaned up a couple of FIXME's sitting around in the code
838 * Altered the conditions under which stray http://... strings are
839 automatically turned into links, to prevent that logic from
840 transforming IMG tags into gibberish.
841 * Set internal version number to 5.21
843 Revision 510.14 2004/06/04 02:29:07 ajc
844 * Fixed bug in "validate new users" screen (thanks Campy)
846 Revision 510.13 2004/06/03 03:21:22 ajc
847 * "Reply" button now carries the message subject into the reply.
849 Revision 510.12 2004/06/02 02:07:54 ajc
850 * setup.c: updated the setup script to configure two /etc/inittab entries,
851 one for http and one for https.
853 Revision 510.11 2004/06/01 21:46:47 ajc
854 * crypto.c: when an SSL connection errors out (and closes) unexpectedly
855 during a read or write operation, do not attempt to finish the operation
856 unencrypted like we do in Citadel. Here in WebCit land it only causes
857 the server to segfault.
859 Revision 510.10 2004/06/01 19:01:22 ajc
860 * netconf.c: widened some of the text entry fields
861 * webcit.h: bumped up the internal version number to 5.20
863 Revision 510.9 2004/06/01 18:44:20 ajc
864 * Return to the old command-line usage (-s for https, service is either
865 http or https but not both)
867 Revision 510.8 2004/06/01 03:32:28 ajc
868 * Add "permanent room" setting to room edit screen
869 * create room -- allow longer strings
871 Revision 510.7 2004/06/01 00:36:43 ajc
872 * Hmmph. Do the session cookie as hex instead of base64. There really
873 are some characters in the base64 set that make HTTP do nasty things.
875 Revision 510.6 2004/05/31 21:43:27 ajc
876 * Added "|END" to the session cookie before base64-ing it. This fixes a
877 problem with certain room names causing the webserver to freak out and
878 break embedded images and stuff. I don't know why.
880 Revision 510.5 2004/05/31 20:34:11 ajc
881 * Message entry using Kevin Roth's excellent cross-platform richtext
884 Revision 510.4 2004/05/31 15:54:13 ajc
885 * "text" and "HTML" options for message entry.
887 Revision 510.3 2004/05/29 03:31:48 ajc
888 * tighten up the space between icons in the iconbar
890 Revision 510.2 2004/05/28 20:24:53 ajc
893 Revision 510.1 2004/05/24 03:02:38 ajc
894 * CSS change to make folder names stand out more in the "Folder View"
896 Revision 510.0 2004/04/30 04:08:58 ajc
899 Revision 506.13 2004/04/30 04:08:47 ajc
900 * Changed internal version number to 5.10
901 * Updated documentation for the new HTTPS service
903 Revision 506.12 2004/04/27 03:21:36 ajc
904 * Prompt for HTTPS port number during setup. We may make this optional.
906 Revision 506.11 2004/04/27 03:16:31 ajc
907 * When running on the same host as Citadel, if no key/cert are found,
908 symlink to Citadel's if possible.
909 * One server binary now forks to start both http and https servers.
911 Revision 506.10 2004/04/21 03:43:39 ajc
912 * Completed remaining SSL fixes. Works in Moz, aIEeee, Konq; self-signed
913 certs are also no longer invalid.
915 Revision 506.9 2004/04/21 02:25:13 ajc
916 * Replaced ctdl_install_certificate() with convenience functions found
917 in the OpenSSL library.
919 Revision 506.8 2004/04/21 02:19:41 ajc
920 * Got HTTPS to work with Mozilla (by twiddling stuff that I still don't
921 understand, but read at http://www.informit.com/articles/article.asp?p=22078
922 ). Still doesn't work with Internet Monopolizer, though.
924 Revision 506.7 2004/04/20 02:32:44 ajc
925 * Allow setup to run seamlessly from within the Citadel Ridiculously
926 Easy Installer by observing the values of environment variables

933 * Minor fix for previous checkin
935 Revision 506.4 2004/04/16 02:59:01 ajc
936 * Completed SSL support. Still doesn't work with all browsers... gotta
939 Revision 506.3 2004/04/15 03:57:00 ajc
940 * Brought over the SSL/TLS stuff from Citadel. I think it's complete but
941 it has a crashy crashy bug in it. Don't use it yet.
943 Revision 506.2 2004/04/13 19:41:36 ajc
944 * GET /freebusy/user.vcf *and* /freebusy/user.vfb now both work.
945 (freebusy data fetch for anonymous Kolab type clients)
947 Revision 506.1 2004/04/10 04:32:59 ajc
948 * Fixed some version and copyright date oopses
950 Revision 506.0 2004/04/10 04:29:30 ajc
953 Revision 505.22 2004/04/10 04:29:20 ajc
954 * Changed internal version number to 5.06
956 Revision 505.21 2004/03/29 04:30:20 ajc
957 * configure.in, Makefile.in: handle $LDFLAGS
959 Revision 505.20 2004/03/20 05:03:14 ajc
960 * Original startup thread becomes a worker thread after initialization.
961 Doing otherwise turns it into a zombie (at least on Linux) and possibly
962 leads to other problems
963 * Filter out NOOP's received in chat
965 Revision 505.19 2004/03/18 04:32:24 ajc
966 * Removed the language in README.TXT which told everyone that chat wouldn't
967 work with a non-local Citadel server, because that's no longer true.
968 * Removed the old chat applet from the static/ directory
970 Revision 505.18 2004/03/18 04:00:44 ajc
971 * Rounded web boxes now look correct in all browsers.
973 Revision 505.17 2004/03/17 18:25:31 ajc
974 * When creating a new user, auto-chain to the "edit user configuration"
975 screen, and subsequently auto-chain to the "edit address book entry"
976 screen. This creates a nice sensible workflow.
978 Revision 505.16 2004/03/15 22:47:09 ajc
979 * Prettied up the chat window a little more.
981 Revision 505.15 2004/03/15 04:27:44 ajc

994 Revision 505.12 2004/03/07 21:31:17 ajc
995 * serv_read() now zeroes out the supplied buffer (with the supplied
996 length) if a server read fails. This causes serv_gets() to return
997 instead of looping endlessly. Fixes chat problem found on linux-ppc.
999 Revision 505.11 2004/03/03 05:21:36 ajc
1000 * Made the chat screen totally kick-ass sweet. The flickering reload
1001 i-frame is now tiny and hidden, and it *appends* new chat data to
1002 the viewable window using JavaScript. No flickering + scrollback!
1003 * Added a help button to the chat screen.
1005 Revision 505.10 2004/02/29 22:52:15 ajc
1006 * Close and clear (set to -1) server socket handle when socket errors are
1007 detected. Fixes a chat problem reported by Winzlo.
1009 Revision 505.9 2004/02/29 05:34:25 ajc
1010 * Display the Chat menu option as "Chat with other users in <roomname>"
1012 Revision 505.8 2004/02/27 05:04:38 ajc
1013 * fix frameset bug in page popups
1015 Revision 505.7 2004/02/26 04:08:56 ajc
1016 * Fixed a problem that made WebCit go to the "no cookies" screen instead
1017 of the logout banner.
1018 * Ford's latest stupid room has a name with more than 64 characters, and
1019 we still had a 64-byte room name in the march_list struct. ooooops...
1021 Revision 505.6 2004/02/26 03:07:26 ajc
1022 * Put the /favicon.ico --> /static/favicon.ico hack back in. Why not?
1024 Revision 505.5 2004/02/25 23:10:28 ajc
1025 * Allow "/do_logout" as a no-frames page
1027 Revision 505.4 2004/02/25 23:00:21 ajc
1028 * Changed the favicon support to LINK tags in the HEAD of static stuff,
1029 to make life easier. (Thanks to prosthetik for this)
1031 Revision 505.3 2004/02/25 15:20:11 ajc
1032 * Support for favicon.ico in the static/ directory
1034 Revision 505.2 2004/02/24 04:06:42 ajc

1043 Revision 504.7 2004/02/19 03:32:38 ajc
1044 * Changed the internal version number to 5.05
1045 * Completed the frames fix
1047 Revision 504.6 2004/02/18 20:08:29 ajc
1048 * Fixed the frameset force reload logic. Now it does the whole frameset
1049 without displaying an error in the main frame.
1051 Revision 504.5 2004/02/18 19:17:51 ajc
1052 * Force reload of frameset if someone tries to escape it. Not perfect
1053 but it mostly works at this poing.
1055 Revision 504.4 2004/02/17 03:37:11 ajc
1056 * Indicate to Citadel that we want Server Generated Invitations when
1057 calendar events are saved. (No longer the default in Citadel server.)
1059 Revision 504.3 2004/02/09 04:49:32 ajc
1060 * Prepare for a way to avoid falling out of the main frameset
1062 Revision 504.2 2004/02/09 03:37:57 ajc
1063 * Changed the thread pool management algorithm. Detecting idle time between
1064 socket accepts was not working reliably on all systems, so we now follow
1065 the same algorithm as the Citadel server (spawn more threads when number
1066 of sessions < number of threads, but keep constrained to pre-defined
1067 minimum and maximum thread count)
1069 Revision 504.1 2004/02/03 03:09:51 ajc
1072 Revision 503.0 2004/01/28 04:31:31 ajc
1075 Revision 502.4 2004/01/28 04:30:48 ajc

1085 Revision 502.1 2003/10/24 02:50:19 ajc
1086 * Clicking "Enter Message" in a room with an Address Book view opens
1087 a blank vCard entry screen.
1089 Revision 502.0 2003/10/23 03:16:50 ajc

1093 * event.c: Found and removed another unquoted multi-line string literal
1094 * webcit.h: changed an #ifdef HAVE_ICAL_H

1097 Revision 501.1 2003/10/22 01:42:12 ajc
1098 * iconbar.c: removed a stray character or two...
1100 Revision 501.0 2003/10/21 04:26:37 ajc
1103 Revision 500.30 2003/10/21 04:26:27 ajc

1106 Revision 500.29 2003/10/17 03:08:28 ajc
1107 * Finished prettying up the vCard display
1109 Revision 500.28 2003/10/17 02:31:45 ajc
1110 * Multi-line string literals are deprecated in GCC 3.1 unless each line
1111 is wrapped in quotes. Performed this fix so it'll compile.
1112 * setup.c: removed references to unused variable tempfile[]
1114 Revision 500.27 2003/10/09 03:17:02 ajc
1115 * Started prettying up the vCard display.
1117 Revision 500.26 2003/10/08 02:33:49 ajc
1118 * Begin work on better handling of vCard display
1120 Revision 500.25 2003/09/04 03:41:27 ajc

1123 Revision 500.24 2003/08/27 04:26:54 ajc
1124 * Split the site configuration screen up into four different screens,
1125 and added a meta-menu
1127 Revision 500.23 2003/08/24 03:31:50 ajc
1128 * Finished the setup program
1129 * Bumped the internal version number to 5.01
1131 Revision 500.22 2003/08/22 00:47:27 ajc
1132 * setup is now working, but it still needs a way to detect a running WebCit
1134 Revision 500.21 2003/08/22 00:25:40 ajc
1135 * Added a skeleton "setup" program to the tree. It does not work yet.
1137 Revision 500.20 2003/08/20 03:48:55 ajc
1138 * Added iconbar shortcut to Contacts room
1139 * Minimum required Citadel is now 6.11
1141 Revision 500.19 2003/08/20 03:07:25 ajc
1142 * Address book "single card" view now suppresses "reading nn message" and
1143 instead shows the letter indices across the top
1144 * Clicking on an address in a vCard now connects to WebCit mail instead
1145 of a browser mailto: link
1147 Revision 500.18 2003/08/19 04:18:43 ajc
1148 * Changed things around in the address book view. Made it sorted and
1149 more clickable and better looking...

1155 * Add the Summary Page to the customizable iconbar
1157 Revision 500.15 2003/08/07 03:51:51 ajc
1158 * Customizable icon bar as: pictures and text, pictures, text
1160 Revision 500.14 2003/08/05 03:52:14 ajc
1161 * First working version of the customizable iconbar. It contains a basic
1162 set of options and now automatically refreshes when it's customized.
1164 Revision 500.13 2003/08/04 03:50:29 ajc
1165 * First cut at the customizable iconbar is done. A bunch of generic options
1166 are there. Still need to get the actual iconbar to refresh when changes
1169 Revision 500.12 2003/08/03 21:02:01 ajc
1170 * More work on customizable iconbar
1172 Revision 500.11 2003/08/02 05:25:46 ajc
1173 * Laid the groundwork for a customizable iconbar

1178 Revision 500.9 2003/07/06 22:06:59 ajc
1179 * When converting "anything that looks like a URL" to a real link, first
1180 make sure that it isn't already inside a link. This fixes most of the
1181 long, ugly URL strings sent by eBay.
1182 * Automatically dismantle mailto: links in HTML messages, and convert
1183 them to WebCit mail links (clicking on it sends the user to the Mail
1184 room and begins composing a new message with the recipient and subject
1185 fields pre-populated).
1187 Revision 500.8 2003/06/29 20:51:21 ajc
1188 * Worked around a rendering bug in Satan's Browser that was causing it
1189 to draw the calendar month view much wider than the actual screen wdith
1191 Revision 500.7 2003/06/28 04:09:37 error
1192 * roomops.c: Backout change to display one less box in the first column in

1195 Revision 500.6 2003/06/28 03:52:51 error
1196 * Don't tell browsers not to cache static documents
1198 Revision 500.5 2003/06/28 03:35:23 error
1199 * roomops.c: Display one less floor in the first column in romlist view
1201 Revision 500.4 2003/06/26 03:37:58 ajc
1202 * Allow anonymous HTTP requests for /freebusy/user%20name.vcf (or .vfb)
1203 This will allow some groupware clients to browse the free/busy times of
1204 other users on the system.
1206 Revision 500.3 2003/06/21 05:17:21 ajc
1207 * Better alignment of system messages
1208 * Exterminated display_error() and replaced it with WC->ImportantMessage
1209 which is displayed in a bubble on top of whatever page you're on next.
1210 * Small cosmetic changes
1211 * Fixed some nesting problems in output_headers()
1213 Revision 500.2 2003/06/20 03:39:27 ajc
1214 * Optimization to floor layout in box view
1216 Revision 500.1 2003/06/20 03:04:26 ajc

1222 Revision 410.50 2003/06/10 04:22:58 ajc
1223 * Updated docs and headers for 5.00 release
1225 Revision 410.49 2003/06/10 04:05:23 ajc
1226 * De-tabled the left side icon bar and reduced one of the graphics, so
1227 that all of the rounded corners show up in Satan's Browser.
1229 Revision 410.48 2003/06/10 03:47:41 ajc
1230 * style.css: added font selection to default <BODY> tag
1232 Revision 410.47 2003/06/06 03:26:03 ajc
1233 * Satan's Browser insists on putting bloody acres of whitespace to the
1234 right of any bulleted list items, making any multi-column table containing
1235 a list take more than the entire screen. Removed all such lists so it
1236 looks ok. If you are reading this and you are a Microsoft employee, please
1237 commit suicide before you break anything else.
1239 Revision 410.46 2003/06/06 02:22:07 ajc
1240 * Changed the upper left and upper right bounded box corners to a solid
1241 blue (#204B78) instead of gradiated, because it was looking funny in
1242 256-color mode. It also looked funny in Internet Explorer, but people
1243 who use Internet Explorer are contributing to terrorism and really don't
1244 deserve Web access in the first place. So I really just fixed this to make
1245 it look good in 256-color Netscape.
1247 Revision 410.45 2003/06/05 21:37:37 ajc
1248 * Cosmetic changes. Attempting to fix b0rken rendering of main menu
1249 in b0rken IE browser. Die, Bill, Die.
1251 Revision 410.44 2003/06/05 03:52:29 ajc
1252 * Buncha cosmetic changes
1254 Revision 410.43 2003/06/04 03:41:25 ajc
1255 * Change the appearance of rooms with and without new messages in the
1256 room list -- now defined using CSS
1258 Revision 410.42 2003/06/03 03:57:42 ajc
1259 * Tightened up the room banner a bit. Smaller padding, smaller font,
1262 Revision 410.41 2003/05/31 21:36:45 ajc
1265 Revision 410.40 2003/05/26 21:05:42 ajc
1266 * availability.c: brought over ical_ctdl_is_overlap() from Citadel. Used
1267 it to complete the free/busy checking for attendee availability.

1270 * event.c: fix compiler warning

1277 * serv_func.c: added utility function read_server_text()
1278 * availability.c: banged out more of this code -- still not complete
1280 Revision 410.36 2003/05/26 03:28:02 ajc
1281 * Getting closer to doing the availability check. Created new source
1282 module 'availability.c' for this purpose. Stub function is in place.
1284 Revision 410.35 2003/05/25 04:25:12 ajc
1285 * siteconfig.c: fixed a spelling error
1286 * event.c: add a "Check attendee availability" button, and the code to
1287 bypass saving the event to the server, do something with it, and then
1288 feed the twiddled data structure back to the form display function for
1289 further editing. What's still missing is the code to do the actual
1292 Revision 410.34 2003/05/24 22:22:35 ajc
1293 * Small stylesheet hack to make it work with b0rken IE
1295 Revision 410.33 2003/05/24 22:13:08 ajc
1296 * Changed the login banner a bit
1298 Revision 410.32 2003/05/20 03:25:41 ajc
1299 * Separate event invitees with newlines instead of commas.
1301 Revision 410.31 2003/05/19 19:55:09 ajc
1302 * summary.c: eliminate compiler warnings about unused variables when
1303 compiling a WebCit service without calendar support
1305 Revision 410.30 2003/05/18 02:05:33 ajc
1306 * More conversion of screens to the new look-and-feel.
1308 Revision 410.29 2003/05/16 04:11:29 ajc
1309 * We don't need no steenking workaround. Problem fixed. MIME parser not
1310 broken. Web server was calling it with bad parameters. All fixed now.
1311 * Slightly tweaked the look of the tabs in the room edit screen. Still looks
1314 Revision 410.28 2003/05/15 04:52:26 ajc
1315 * Minor workaround in web forms to handle mime parser problem in uploads
1317 Revision 410.27 2003/05/15 03:35:59 ajc
1318 * look and feel overhaul -- almost done!
1320 Revision 410.26 2003/05/14 03:46:35 ajc
1321 * More background cleanup
1323 Revision 410.25 2003/05/05 17:19:46 ajc
1324 * Cleanups to summary page when running on a non ical enabled system
1325 * Use non breaking spaces in summary page box titles
1327 Revision 410.24 2003/05/04 04:22:41 ajc
1328 * Display body of messages on a white background. I am doing this in order
1329 to prepare for making the general background of the screen a darker color.
1331 Revision 410.23 2003/05/04 02:54:55 ajc
1332 * Summary page now uses our cutesy new rounded window boxes
1334 Revision 410.22 2003/05/03 21:28:41 ajc
1335 * Added in a slick new box style and put the room lists in it
1337 Revision 410.21 2003/05/03 16:57:04 ajc
1338 * In the 'folders' and 'portal' views, change the folder delimiter
1339 from / to \ to avoid conflict with room names that have slashes
1341 Revision 410.20 2003/05/03 16:23:29 ajc
1342 * Enforce three columns in portal view of room list
1344 Revision 410.19 2003/05/03 04:52:32 ajc
1345 * Added an experimental new "portal view" to the room list options
1347 Revision 410.18 2003/05/02 03:23:41 ajc
1348 * Minor change to room list algorithm
1350 Revision 410.17 2003/05/01 15:33:05 ajc

1358 * Added the ability to compose messages with file attachments uploaded from
1361 Revision 410.14 2003/04/27 04:46:02 ajc
1362 * Replace LKRN/LKRO in "folders view" room list with a single LKRA that
1363 observes the flag designating the presence of new messages. (The "rooms
1364 view" uses an LKRN/LKRO pair *per floor* and has the same inefficiency,
1365 but that view may get axed soon.)
1367 Revision 410.13 2003/04/26 21:57:53 ajc
1368 * tcp_sockets.c: when an outgoing socket connection fails, close the socket
1369 before returning an error code to avoid a file descriptor leak

1372 * Repaired all my b0rken COLOR tags
1373 * Replaced most FONT tags with SPAN tags
1376 Revision 410.11 2003/04/19 19:58:10 ajc
1377 * Lots of great changes from Nick to make the site CSS-enabled.
1379 Revision 410.10 2003/04/14 04:04:40 ajc
1380 * First cut of CSS-izing WebCit. Probably b0rken.
1382 Revision 410.9 2003/04/09 04:02:32 ajc
1383 * Remove the defaulthost/defaultport vs. c_host/c_port stuff -- we haven't
1384 supported the idea of one WebCit connecting to multiple Citadels for a
1385 long time. Now it's just one set of variables, called ctdlhost/ctdlport.
1386 * When connecting to Citadel through a Unix domain socket, don't try to make
1387 the Java chat applet available.
1389 Revision 410.8 2003/03/31 03:32:19 ajc
1390 * messages.c: check for 000 terminator while parsing RFC822 headers to
1391 prevent getting hung up while displaying certain badly formatted messages.
1393 Revision 410.7 2003/03/30 06:13:19 ajc
1394 * When reading from the server, do not treat CR as end-of-line because
1395 there's probably an LF coming after it. Instead, keep reading to the LF
1396 and then strip both.
1397 * Do not underline links in the icon bars
1399 Revision 410.6 2003/03/17 04:17:41 ajc
1400 * Call to accept() was being made with an uninitialized variable for the
1401 third argument. Changed the second and third argument to NULL and 0 because
1402 we don't really need accept() to fill up a buffer full of information that
1403 we'll never use. (Thanks to SteveV for reporting the bug and helping to
1405 * Removed the mutex wrapper around select() because we don't need it. All
1406 idle worker threads now block on select() and one of them will wake up when
1407 a connection arrives.
1409 Revision 410.5 2003/03/15 20:55:03 ajc
1410 * When a requested image is not available on the Citadel server, send a
1411 1x1 transparent GIF instead of 404 error.
1413 Revision 410.4 2003/03/14 04:21:57 ajc
1414 * clone events to be encapsulated before saving, because the original
1415 instance may already have a parent, and that makes crashy crashy
1417 Revision 410.3 2003/03/13 05:57:17 ajc
1418 * More encapsulation. Warning: there are bugs in this!!
1420 Revision 410.2 2003/03/13 05:20:23 ajc
1421 * Various changes to the calendar service to handle messages containing
1422 fully encapsulated VCALENDAR components instead of only unencapsulated
1423 VEVENT subcomponents. We have to move in this direction for compatibility
1424 with other products.
1426 Revision 410.1 2003/03/01 22:07:19 ajc
1427 * New user registration, as well as existing user re-registration, now
1428 uses the vCard editing screen.
1429 * Administratively editing users' address book entries now works again,
1430 mainly due to a fix in the Citadel server. Now requiring Citadel 6.06
1431 in order to enforce this.
1433 Revision 410.0 2003/02/19 03:49:33 ajc
1436 Revision 400.90 2003/02/19 03:49:17 ajc
1437 * latest config.guess and config.sub from www.gnu.org
1439 Revision 400.89 2003/02/07 04:44:17 ajc
1440 * Replaced sleep() with a function that sleeps using select() in order to
1441 avoid potential issues with SIGALRM. Possible fix for weird behavior
1442 when running on a Macintosh.
1444 Revision 400.88 2003/01/29 22:32:07 ajc
1445 * Shuffled some code and comments around; minor cleanup
1447 Revision 400.87 2003/01/28 15:37:12 ajc
1448 * All functions which read binary data from the server now make use of the
1449 read_server_binary() function in tools.c
1450 * Binary reads from server now have safety code to prevent infinite loops
1451 * All output of MIME objects is now done with http_transmit_thing()
1453 Revision 400.86 2003/01/19 06:28:04 ajc
1454 * Minimum required Citadel version 6.05
1456 Revision 400.85 2003/01/16 04:41:26 ajc
1457 * When displaying edit controls for time of day in the calendar, only show
1458 minutes that are multiples of 5 ... unless the existing value is not a
1459 multiple of 5, in which case we show that too.
1461 Revision 400.84 2003/01/15 17:34:04 ajc
1462 * event.c: fixed a misspelling
1463 * config.guess, config.sub: updated using latest from ftp.gnu.org
1465 Revision 400.83 2003/01/14 04:21:27 ajc
1466 * Only offer views which make sense for the default view of a room
1468 Revision 400.82 2003/01/13 03:34:33 ajc
1469 * Get ready for the 4.10 release
1471 Revision 400.81 2003/01/12 23:22:53 ajc
1472 * configure.in: check for libical v0.24 or newer
1474 Revision 400.80 2003/01/07 04:56:17 ajc
1475 * Complete the free/busy transparency handling in the form
1476 * Default times for new events are now in the correct timezone
1478 Revision 400.79 2003/01/06 18:01:35 ajc
1479 * Begin handling of TRANSP property to show event times as free or
1480 busy (not finished).
1482 Revision 400.78 2003/01/05 21:02:14 ajc
1483 * Summary page: three columns are now all the same width
1485 Revision 400.77 2003/01/05 20:56:05 ajc
1486 * minor fix for previous checkin
1488 Revision 400.76 2003/01/05 20:51:01 ajc
1489 * Display PARTSTAT for attendees
1491 Revision 400.75 2003/01/05 05:01:00 ajc
1492 * Add "today's calendar events" to the summary page.
1494 Revision 400.74 2003/01/05 04:27:28 ajc
1495 * Add "Tasks" to the summary page
1497 Revision 400.73 2002/12/28 05:44:09 ajc
1498 * ical_dezonify.c: brought over new version from the Citadel source (again)
1500 Revision 400.72 2002/12/28 05:12:45 ajc
1501 * ical_dezonify.c: brought over new version from the Citadel source.
1503 Revision 400.71 2002/12/26 04:04:48 ajc
1504 * Perform CHEK command when automatically establishing sessions, not just
1505 when one is explicitly created. Some stuff is missing otherwise.
1507 Revision 400.70 2002/12/25 23:18:06 ajc
1508 * Be more strategic about when to call ical_dezonify()
1509 (This may be the last set of fixes. I hope so.)
1511 Revision 400.69 2002/12/25 21:39:38 ajc
1512 * ical_dezonify.c: added.
1513 * calendar.c: convert incoming ical messages to UTC
1514 (the usual routines will then convert them to local time for display)
1516 Revision 400.68 2002/12/25 07:06:00 ajc
1517 * Tweaked the code to work with libical 0.24
1519 Revision 400.67 2002/12/20 04:50:00 ajc
1520 * When saving a calendar event, increment the SEQUENCE property.
1522 Revision 400.66 2002/12/18 05:03:39 ajc
1523 * In the calendar code, changed all "struct tm *" to "struct tm" and changed
1524 all "tm = localtime(foo)" to "memcpy(&tm, localtime(foo), sizeof(struct tm))"
1525 Because the libc-allocated buffer was getting clobbered.
1526 * This fixes the problem fleeb reported with Feb 1 events making it go nuts.
1528 Revision 400.65 2002/12/17 05:01:39 ajc
1529 * Prettied up the calendar day view layout
1530 * Hour/minute editing fields now use am/pm hours and 2-digit minutes
1532 Revision 400.64 2002/12/16 04:43:30 ajc
1533 * Correctly handle local time zone when figuring out which day and time to
1534 display events on calendar month/day views. This also seems to have
1535 fixed the bug that was causing events to sometimes get lost when saved.
1537 Revision 400.63 2002/12/15 05:50:59 ajc
1538 * Form editing of date/time fields now assumes that the icaltimetype being
1539 manipulated is in UTC. It converts to/from local time for editing.
1541 Revision 400.62 2002/12/10 23:25:47 ajc
1542 * Display attendees in message view of calendar objects
1544 Revision 400.61 2002/12/07 22:12:59 ajc
1545 * Handle incoming RSVP's for meetings. (Note: this will not actually work
1546 until I implement the Citadel server function which it calls.)
1548 Revision 400.60 2002/11/30 21:34:51 ajc
1549 * Submit organizer in a hidden field, in case the server needs it
1551 Revision 400.59 2002/11/30 04:46:46 ajc
1552 * First cut at adding/removing attendees to an event
1553 (Actual invitations should be sent by the Citadel server)
1555 Revision 400.58 2002/11/29 23:56:19 ajc
1556 * Completed "me as organizer" -- the user's own e-mail address is inserted
1557 as the organizer of new events. Detect when the user is the organizer and
1558 enable/disable the attendees box accordingly.
1560 Revision 400.57 2002/11/29 16:38:37 ajc
1561 * Started some "me as organizer" stuff. (BROKEN BUILD ... I'll fix soon.)
1563 Revision 400.56 2002/11/28 06:03:24 ajc
1564 * Issue an ISME command when editing an event, to determine whether the user
1565 viewing the event is the organizer. (Will use this later to allow/disallow
1566 sending out invitations.)
1568 Revision 400.55 2002/11/26 05:01:04 ajc
1569 * Began handling attendee fields
1571 Revision 400.54 2002/11/16 23:40:11 ajc
1574 Revision 400.53 2002/11/16 23:15:02 ajc
1575 * Make the "all day event" shadebox smaller (month view) - no border.
1576 * Fixed bug that caused any events following an all day event to also appear
1579 Revision 400.52 2002/11/16 05:40:54 ajc
1580 * When adding new events to the calendar, default to the month [and day]
1581 currently being viewed.
1582 * Hotlink each hour of the day view to an add-new-event for that day/hour.
1584 Revision 400.51 2002/11/15 05:05:47 ajc
1585 * Put in back/forward (yesterday/tomorrow) links in calendar day view
1587 Revision 400.50 2002/11/15 04:11:46 ajc
1588 * Added even more nifty JavaScript to cause the hour/minute and end date
1589 fields of a calendar event form to render as disabled when the "all day
1590 event" box is checked -- not just when the user checks the box, but also
1591 when the box begins its life already checked.
1593 Revision 400.49 2002/11/14 04:59:40 ajc
1594 * Correctly serialize and save all day events using date instead of date/time
1596 Revision 400.48 2002/11/13 04:49:23 ajc
1597 * "All day event" shows as a single checkbox, instead of one for the start
1598 time and one for the end time. Added nifty JavaScript to zero and shade
1599 the hour/minute and all end time fields when all-day-event is checked.
1601 Revision 400.47 2002/11/12 05:57:27 ajc
1602 * Display a nicer looking screen when replying to calendar invitations
1603 * When displaying day view, don't show all day events twice
1604 * Day or month view: denote all day events by displaying them inside
1607 Revision 400.46 2002/11/12 03:26:39 ajc
1608 * Tell the user about broken Citadel server connections instead of
1609 simply printing "Goodbye"
1611 Revision 400.45 2002/10/23 04:11:38 ajc
1612 * Detect when a meeting invitation is actually an update for an existing UID
1613 and tell the user so.
1615 Revision 400.44 2002/10/21 20:16:38 ajc
1616 * Display conflicts nicely
1618 Revision 400.43 2002/10/21 18:29:14 ajc
1619 * Ask server to hunt for conflicts when displaying a meeting invitation
1621 Revision 400.42 2002/10/19 21:28:32 ajc
1622 * Moved the calendar meeting request reply functionality to the Citadel server

1628 Revision 400.40 2002/10/19 04:16:37 ajc
1629 * Save an incoming meeting request into the user's calendar.
1631 Revision 400.39 2002/10/18 20:55:05 ajc
1632 * Began work on meeting request accept/decline
1634 Revision 400.38 2002/10/16 19:16:39 ajc
1635 * Fixes and updates to build WebCit on Linux for IBM S/390
1637 Revision 400.37 2002/10/09 04:12:44 ajc
1638 * Templatized trailing HTML
1639 * Templatized "new start page" page
1640 * Added global substitution macros
1642 Revision 400.36 2002/10/09 03:51:01 ajc
1643 * Templatized the <HEAD> section of HTML
1645 Revision 400.35 2002/10/07 23:03:38 ajc
1646 * messages.c: don't display room name field when it's blank
1648 Revision 400.34 2002/10/07 04:10:37 ajc
1649 * When displaying meeting invitations, only show date/time for VEVENT
1650 subcomponents. Date/time for other subcomponents are irrelevant.
1651 * Cleaned up HTML display of meeting invitations.
1653 Revision 400.33 2002/10/03 03:40:31 ajc
1654 * Worked on meeting accept/decline a little bit
1656 Revision 400.32 2002/09/30 03:58:35 ajc
1657 * Dabbled in handling incoming meeting requests
1659 Revision 400.31 2002/09/29 20:15:43 ajc
1660 * Completed the calendar day view
1662 Revision 400.30 2002/09/28 04:01:30 ajc
1663 * started fleshing out the calendar day view
1665 Revision 400.29 2002/09/27 21:19:28 ajc
1668 Revision 400.28 2002/09/27 18:31:33 ajc
1669 * Properly handle VEVENT saves (fixed nasty loopy loopy bug)
1670 * After saving a VEVENT, return to the correct calendar view and date
1672 Revision 400.27 2002/09/27 17:15:44 ajc
1673 * Removed the gzip compression stuff due to bugs in Internet Explorer.
1675 Revision 400.26 2002/09/27 04:37:21 ajc
1676 * New, buggy versions of event editing screens
1678 Revision 400.25 2002/09/26 22:00:16 ajc
1679 * Fixed buggy month-selection algorithm (January is month 0 in 'struct tm' but
1680 month 1 in libical functions)
1682 Revision 400.24 2002/09/25 21:57:13 ajc
1683 * Keep track of msgnums in the two-pass calendar loop, so we can hotlink to
1686 Revision 400.23 2002/09/24 04:12:34 ajc
1687 * Rough cut of the two-pass calendar display routines (first pass: go thru
1688 messages gathering VEVENT items; second pass: render calendar with data)
1690 Revision 400.22 2002/09/23 04:01:33 ajc
1691 * Presentation changes to calendar month view
1693 Revision 400.21 2002/09/22 05:20:27 ajc
1694 * Began implementing month view
1696 Revision 400.20 2002/09/21 04:38:05 ajc
1697 * Added utility functions for displaying vcalendar timestamps in web forms
1698 and translating form data back to timestamps.
1699 * Completed the "edit task" and "add new task" screens.
1701 Revision 400.19 2002/09/20 20:28:08 ajc
1702 * Smooth transition between "list tasks" & "edit task" screens
1704 Revision 400.18 2002/09/20 03:54:44 ajc
1705 * Display the "Tasks" view as a bulleted list with each task clickable
1706 * Clicking brings up an (unfinished) "edit task" screen
1708 Revision 400.17 2002/09/18 21:44:02 ajc
1709 * display VTODO parameters
1711 Revision 400.16 2002/09/17 04:21:00 ajc
1712 * Handler chains for VCALENDAR and VTODO types
1714 Revision 400.15 2002/09/17 03:37:10 ajc
1715 * Implemented a 'display handler' infrastructure for various groupware types
1717 Revision 400.14 2002/09/16 03:35:12 ajc
1718 * Just a bunch of glue code to iterate through the various types of ical
1719 objects we could encounter
1721 Revision 400.13 2002/09/15 04:05:41 ajc
1722 * Process calendar object subcomponents
1724 Revision 400.12 2002/09/15 03:40:13 ajc
1726 * When a text/calendar MIME type is discovered in a message, send it to
1727 the (currently skeleton) parser in calendar.c
1728 * calendar.c: skeleton parser for calendar objects which currently just
1729 creates an icalcomponent object and frees it.
1731 Revision 400.11 2002/09/15 03:16:24 ajc
1732 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
1733 function namespace in libical
1735 Revision 400.10 2002/09/15 02:50:55 ajc
1736 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
1738 Revision 400.9 2002/09/14 21:33:31 ajc
1739 * Backed out compression of inlines -- not all browsers appear to handle it
1741 Revision 400.8 2002/09/14 20:20:29 ajc
1742 * Attempting to push more stuff through compression. I've introduced some
1743 sort of deadlock bug that I can't seem to find yet...
1745 Revision 400.7 2002/09/14 20:00:22 ajc
1746 * Compress output_image() graphics
1748 Revision 400.6 2002/09/14 16:26:35 ajc
1749 * output_image() now reads the entire image from Citadel into a buffer before
1750 sending it to the browser (for performance reasons, and so it can compress)
1752 Revision 400.5 2002/09/14 04:52:59 ajc
1753 * Look for the "libical" calendaring library and link it in if present...
1755 Revision 400.4 2002/09/14 04:02:36 ajc
1756 * Finished gzip compression of dynamic pages (when browser supports it)
1758 Revision 400.3 2002/09/13 20:40:53 ajc
1759 * Detect when the client browser is capable of gzip encoding
1760 (actual encoding is not implemented yet)
1762 Revision 400.2 2002/09/13 15:54:40 ajc
1763 * Reversed the above change because I broke it somehow
1765 Revision 400.1 2002/09/11 22:46:59 ajc
1766 * Started adding in compression and calendaring library detects (not finished)
1768 Revision 400.0 2002/09/09 03:56:11 ajc
1769 * This is version 4.00
1771 Revision 323.68 2002/09/09 03:51:01 ajc
1772 * In the HTML-to-HTML converter:
1773 --> Open links in new window (as with text msgs)
1774 --> Convert loose URL's to hot links (as with text msgs)
1776 Revision 323.67 2002/09/06 03:59:11 ajc
1777 * Added an "About this server" panel to the Summary page.
1778 (Useless fluff, but better than an empty column.)
1780 Revision 323.66 2002/08/26 02:57:06 ajc
1781 * Rooms listed on the summary page are now clickable-gotoable
1783 Revision 323.65 2002/08/26 01:24:09 ajc
1784 * Added a "summary" page (rather sparse for now)
1786 Revision 323.64 2002/08/24 15:30:48 ajc
1787 * GET instead of POST for listsub. Also add a 'Back...' link.
1789 Revision 323.63 2002/08/24 05:59:24 ajc
1790 * Bugfixes and cosmetic changes to listsub system
1792 Revision 323.62 2002/08/23 03:37:19 ajc
1793 * Finished all of the subscribe/unsubscribe/confirm stuff! (I think)
1795 Revision 323.61 2002/08/22 03:55:47 ajc
1796 * 'unsubscribe' command (but not 'confirm unsubscribe')
1798 Revision 323.60 2002/08/21 21:58:37 ajc
1799 * Completed self-service list subscription via web.
1800 (Still need to implement unsubscribe.)
1802 Revision 323.59 2002/08/16 22:06:51 ajc
1805 Revision 323.58 2002/08/16 03:51:12 ajc
1806 * I think I've finally nailed the 'no session' pages now...

2125 queue length to 100 for use on big systems. Also, during startup, the
2126 initial startup thread now exits after creating the worker threads, instead
2127 of becoming a worker thread itself. For some reason Solaris had problems
2128 with the latter method.

2261 Revision 211.19 2000/05/18 02:33:39 ajc
2262 * Don't call whobbs() directly after changing masq room/host, it screws up the

2277 Revision 211.15 2000/04/20 02:42:23 ajc
2278 * tcp_sockets.c: changed memcpy() to memset() in tcp_connectsock; this was
2279 crashing every session, every time. (?)
2280 * End the session after displaying robots.txt or nocookies.html, to prevent
2281 big session logjams when either of these conditions are met
2283 Revision 211.14 2000/04/15 15:43:46 nbryant
2284 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

2372 * Finished the overhaul. Now to tune...
2374 Revision 1.111 1999/12/03 17:59:53 ajc
2375 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
2376 pseudocode so the build is currently broken.
2378 Revision 1.110 1999/12/03 16:37:46 ajc
2379 * Repaired HTTP output for image transfers and static content
2381 Revision 1.109 1999/12/03 05:09:54 ajc
2382 * Rewrote the HTTP engine and application coupling to run in a worker thread
2383 model and to run as a single multithreaded program (eliminated helper

2408 Revision 1.101 1999/10/06 02:44:02 ajc
2409 * Per Nick's request, removed the key bindings stuff. He knows how to fit
2410 it back in when it's fixed. Also added more attempts at cache disabling,
2411 but it still doesn't work in the StarOffice browser. I don't know why.
2413 Revision 1.100 1999/10/02 03:26:14 ajc
2414 * Merged in Nick's bit of JavaScript to handle key commands.
2415 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
2416 in a text field. Right now you can't even log in.
2418 Revision 1.99 1999/09/01 01:06:11 ajc

2430 to a Citadel server fails.
2431 * messages.c: don't auto-link URL's in messages if it would cause
2434 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2435 * Recompiled the Java chat applet using a genuine JDK 1.0.2

2438 Wed Jun 30 19:19:59 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2439 * Added support for "robots.txt" telling spiders to go away.

2470 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

2474 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2475 * Fixed the behavior of the "forget room" routine, to properly handle
2476 the transition back to the Lobby after it's all done.
2477 * Added ExpressMessageCat() to allow code to send the user messages
2478 along with incoming express messages
2479 * WebCit now sends the name of the end user's browser as the client
2480 name in a Citadel IDEN command rather than its own name.
2482 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2483 * Minor code cleanups

2493 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2494 * Replaced _most_ gotoroom() calls with smart_goto(), a version

2506 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2507 * Reworked a lot of the structure, made more HTML "embeddable"
2508 * Changed the noframes mode to display "fake" frames using tables
2510 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nick@ulster.net>
2511 Changed some output formatting (mainly <FONT> tags).
2512 Changed who.c to use urlescputs() rather than escputs()
2513 in urls so GOTOs and User Profiles work when the string has a
2516 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2517 http://www.webreference.com/dhtml/column18/menuFrLoad.html
2518 How to cause "onLoad=" to cause a sibling frame to refresh without
2519 having to use the nonportable HTTP "Window-Target:" directive. Began
2520 implementation of this; it should allow portable NS/IE compatibility.
2522 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2523 * Implemented "access level required to create rooms"

2526 * webcit.c: modified getz() to *exit* the program when fgets()
2527 returns an error. This is actually the desired behavior; it would
2528 otherwise busy-loop forever on a broken pipe.
2530 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2531 * webcit.c: added to getz() the ability to return an error code;
2532 implemented this in the main loop, hopefully fixing problems

2534 * Added HTTP "User-agent:" detection
2535 * wildmat.c, braindamage.c: added
2536 * Initial value of 'noframes' is now set by the braindamage check
2537 * Ran everything through "indent -kr -i8"
2538 * roomops.c: in room list, print a in otherwise empty cells
2540 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
2541 * context_loop.c: warning fix
2542 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
2544 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2545 * Resolve the name of the connecting host and pass it on to Citadel
2547 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2548 * wDumpContent() is now responsible for </BODY></HTML> most of the
2549 time (parameter settable) so that the main menu can easily be
2550 embedded in every page when running in noframes mode
2551 * noframes mode selection is now carried in the cookie
2553 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2554 * Made the frames stuff less dependent on the HTML TARGET= directive
2555 and more dependent on the HTTP Window-target: directive.
2556 * Made the system semi-navigable in noframes mode.
2558 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2559 * Brought over the new room listing code and <G>oto heuristics
2560 from the main Citadel tree, to pay attention to floor/room ordering
2562 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2563 * Modified the back end of mime_parser to use callbacks instead of
2564 doing something specific. Now we can use it elsewhere.
2566 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2567 * Fixed the bugs in "Site-wide configuration"
2568 * Added a "generic server commands" screen
2570 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2571 * Reduced the multiple cookies down to one cookie combining all data.
2573 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2574 * Removed wc_host and wc_port cookies.
2575 * Added an "edit your session" screen to change your wholisting.

2578 * Added "enter registration"
2579 * Set up automatic trigger of Enter Registration when the server
2581 * Established that a one-to-one WebCit/Citadel correspondence will
2582 be required. No big deal due to shared code segments.
2583 * Added "change password"
2584 * Added networking configuration screens. These still need testing.
2585 * Added a "kill session" link to each line of the wholist when
2586 logged in as an aide, and the screens to perform this operation.
2588 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2589 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
2590 * "Finished" the MIME parser.

2598 * Wrote mime_parser.c for handling of image uploads. This will also
2599 be used in future Citadel MIME projects.

2610 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2611 * Changed the "auto read new" functionality from a meta refresh tag
2612 to an "onload" directive (the former was causing graphics problems)
2613 * Added "create room"

2627 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2628 * Replace "Citadel" in menu bar with the Citadel logo
2630 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>

2633 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2634 * context_loop.c: Moved "remove session" into its own function.
2635 Check for dead webcit child process before each transaction.

2655 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
2656 * context_loop.c: After fork(), child process closes the HTTP socket
2657 so when the parent process closes it, it actually _does_ close.
2658 Otherwise, aIEeeee and possibly other browsers will hang.
2659 * Added support for graphics images retrieved from the Citadel server.
2660 * Set up login banner graphic and background image graphic
2662 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
