3 Fri Dec 2 11:01:30 EST 2005 ajc
4 * wclib.js: fixed a syntax error
6 Thu Dec 1 17:46:18 EST 2005 ajc
7 * which_div_expanded is now persistent across sessions
9 Thu Dec 1 17:42:48 EST 2005 ajc
10 * which_div_expanded is now persistent across page loads
12 Thu Dec 1 17:15:32 EST 2005 ajc
13 * Clicking on the expanded floor div collapses it.
15 Thu Dec 1 17:03:15 EST 2005 ajc
16 * More style changes to the new room list, mainly with regard to font size
19 Thu Dec 1 14:35:09 EST 2005 ajc
20 * Added icons to the new room list
22 Thu Dec 1 00:42:01 EST 2005 ajc
23 * The iconbar roomlist, when selected, is now persistent across page loads
24 and even between sessions. We also cache the list for up to 5 minutes so
25 it doesn't have to load from the Citadel server over and over again.
27 Wed Nov 30 23:59:11 EST 2005 ajc
28 * Shortened some of the string lengths in struct wcsession. We really don't
29 need all those 4096 byte moby-buffers everywhere.
31 Tue Nov 29 23:53:33 EST 2005 ajc
32 * Drag-and-drop move messages is now complete.
34 Tue Nov 29 23:20:23 EST 2005 ajc
35 * Completed the JavaScript-detection of room names in the iconbar as drop
38 Mon Nov 28 23:04:13 EST 2005 ajc
39 * Made the iconbar room list somewhat usable (collapse/expand). It is not yet
40 a drop target, though, which is why we did all this in the first place.
42 Mon Nov 27 21:28:03 CET 2005 dothebart
43 * migrate to _GNU_SOURCE and uselocale() to be threadsafe.
45 Sun Nov 27 21:28:03 EST 2005 ajc
46 * Eliminated the use of tmpnam() to shut up compiler warnings.
48 Sun Nov 27 18:42:15 CET 2005 dothebart
49 * Detect locale from Browser Environment
51 Sun Nov 27 18:42:15 CET 2005 dothebart
52 * staticaly bind codeset to utf8.
54 Wed Nov 23 23:32:04 EST 2005 ajc
55 * Placed a mini roomlist in the iconbar. This is not in its final form.
57 Wed Nov 23 16:42:15 CET 2005 dothebart
58 * added missing german translations
59 * changed multi line strings with empty string in first line to be searchable
60 from real untranslated strings
62 Wed Nov 23 11:04:24 EST 2005 ajc
63 * auth.c: localized "User name:" and "Password:" prompts
65 Tue Nov 22 21:44:15 EST 2005 ajc
66 * Fixed the unresponsive msgomatic in the bulletin board view.
68 Tue Nov 22 00:00:46 EST 2005 ajc
69 * Set up a toggleable iconbar that can switch between the menu and a room
70 list. The room list is not yet implemented, so a simple placeholder is
73 Mon Nov 21 22:47:17 EST 2005 ajc
74 * messages.c, webcit.css: message buttons (Reply, ReplyQuoted, etc.) are now
75 in a smaller font (new style "msgbuttons" defined in the stylesheet)
76 * Reply and ReplyQuoted no longer generate an empty "Re:" subject if the
77 message being replied to has no subject.
79 Mon Nov 21 22:30:31 EST 2005 ajc
80 * create-pot.sh: now creates a new webcit.pot file and automatically merges
81 it into all *.po files, allowing an easy way for translators to access
83 * axdefs[] (Access level definitions) -- now ready for localization.
85 Mon Nov 21 16:59:43 CET 2005 dothebart
86 * add some script to wrap the debian package build that does some magic about
87 the versioning in the package and the webcit system
88 * added first try of a package that will install webcit via mod_proxy into
89 the debian apache system
90 * modified package build and postinst script do include subdirectories new
91 since tiny_mce was added.
94 Sun Nov 20 22:22:37 EST 2005 ajc
95 * Moved the definition of INADDR_NONE to webcit.h, where it will be effective
96 in all locations where it is needed. Fixes the build on Solaris 10.
98 Fri Nov 18 23:55:29 EST 2005 ajc
99 * Put in some infrastructure for generating and maintaining .po files
101 Fri Nov 18 23:24:09 EST 2005 ajc
102 * Threw away most of the gettextize-generated build system in the po/
103 directory, and replaced it with a very simple Makefile.in.in instead.
105 Thu Nov 17 11:32:39 EST 2005 ajc
106 * More changes to try to get the po/ directory to build properly. It's still
107 not working. If you want to run WebCit using the current tree, be sure to
108 configure with --disable-nls
110 Tue Nov 17 00:03:20 EST 2005 ajc
111 * Assorted tweaks to activate the translations...
113 Tue Nov 15 21:58:09 EST 2005 ajc
114 * Checked in po/de.po, a German translation submitted by Wilifried Goesgens.
115 Now I just have to figure out how to activate it.
117 Sun Nov 13 23:08:58 EST 2005 ajc
118 * Added an '-f' command line option to allow WebCit to follow the
119 'X-Forwarded-For:' HTTP header, if present.
120 * Added missing HTTP headers for /listsub
121 * Discovered the style -moz-user-select:none and applied it to the mailbox
122 summary table, to prevent text select from ruining the appearance of our
123 beautiful drag and drop function.
124 * Strip prepended '/webcit' in requested url's. This may allow us to handle
125 incoming proxy requests from a front end web server.
126 * Don't require a session cookie for static content.
128 Thu Nov 10 17:37:32 EST 2005 ajc
129 * Completed the implementation of a simple drop target for messages. Right
130 now it just drops to trash. Need to do a folder list drop now.
132 Wed Nov 9 23:07:44 EST 2005 ajc
133 * Removed arbitrary upper bound in message select array, after realizing that
134 JavaScript arrays don't need to have their size declared.
136 Tue Nov 8 23:50:01 EST 2005 ajc
137 * Mailbox view: selected messages are now draggable!! (Now we just need to
138 implement a place to drop them.)
140 Tue Nov 8 00:44:19 EST 2005 ajc
141 * Now it resizes on mousemove instead of mouseup. Very nice animated effect.
143 Tue Nov 8 00:36:46 EST 2005 ajc
144 * First cut of message list resize. It works but it resizes on mouseup.
146 Mon Nov 7 10:45:18 EST 2005 ajc
147 * Disable the I-bar cursor when hovering over message summary lines in the
148 mailbox view; go with the default pointer instead.
150 Sun Nov 6 23:27:21 EST 2005 ajc
151 * Mailbox summary view -- headers are now ever-present; they do not scroll
154 Sun Nov 6 22:30:54 EST 2005 ajc
155 * Changed keypress handling so that it works not only in web browsers, but in
156 Internet Explorer as well.
158 Sun Nov 6 12:26:43 EST 2005 ajc
159 * Message delete: table row delete is now handled by a script.aculo.us effect
160 instead of by just clearing out the innerHTML of the table row div, because
161 IE barfs on the latter.
163 Sat Nov 5 22:53:29 EST 2005 ajc
164 * Found and removed more absolute URL's.
166 Sat Nov 5 00:50:25 EST 2005 ajc
167 * The checkboxes are gone! Implemented ajax delete of selected messages,
168 via either the Delete button or the Delete key.
170 Fri Nov 4 23:47:23 EST 2005 ajc
171 * Multi select using ctrl now handles the condition of a message already being
172 selected and the user doing ctrl-click to deselect it.
174 Fri Nov 4 17:04:49 EST 2005 ajc
175 * Multi select (using the ctrl key) is now working.
177 Thu Nov 3 23:44:55 EST 2005 ajc
178 * Removed all of the absolute URL's.
180 Thu Nov 3 11:11:37 EST 2005 ajc
181 * Removed the 'mark message as seen' C code (in the mailbox view) because it
182 was no longer getting called. Implemented this in JavaScript using an ajax
183 call plus a new WebCit function to perform generic server commands using
184 ajax. Also reinstated the removal of bold font weight for messages
185 transitioning from unseen to seen (again, in JavaScript).
187 Wed Nov 2 23:45:16 EST 2005 ajc
188 * Mailbox view -- onClick is now implemented by a JavaScript function which
189 is defined in wclib.js -- now, it not only handles the Ajax load of the
190 message into the preview pane, but it also highlights the table row, and
191 remembers the highlighting so it can be turned off when another row is
192 selected. This is if course a prelude to ajaxifying the table...
194 Wed Nov 2 15:57:37 EST 2005 ajc
195 * Switched the mailbox summary back to a table. This is tabular data and it
196 ought to be marked up as a table. We went to fixed width floating div's in
197 order to use script.aculo.us 'draggable' but dragging the entire row ended
198 up looking like crap, and it didn't appear that we would be able to drag
199 outside the source div anyway. So we're going back to the table.
201 Wed Nov 2 15:07:21 EST 2005 ajc
202 * "Read reverse" (or rather, an "oldest to newest / newest to oldest"
203 setting) is now selectable in the message board view.
205 Wed Nov 2 00:10:28 EST 2005 ajc
206 * Implemented the webcit equivalent of "read reverse" for bbs read mode.
207 All we need now is to add the user options to select it.
209 Tue Nov 1 22:30:15 EST 2005 ajc
210 * useredit.c: added in the missing "Permission to send Internet mail"
211 option for editing a user account.
213 Mon Oct 31 22:29:39 EST 2005 ajc
214 * messages.c: the summary line for each message is now a SPAN instead of
215 a DIV. This was done because we needed the SPAN anyway to apply styles,
216 and saves some space.
218 Sun Oct 30 21:58:23 EST 2005 ajc
219 * summary.c: fixed the date display.
221 Sun Oct 30 01:40:35 EDT 2005 ajc
222 * messages.c: the summary line for each message is now a div containing fixed
223 width floating spans instead of a table row. This is being done as part of
224 the preparations to ajaxify the presentation of this data.
226 Thu Oct 27 16:57:38 EDT 2005 ajc
229 Wed Oct 26 16:19:24 EDT 2005 ajc
230 * Bumped internal version number to 6.31. Minimum Citadel server required
233 Wed Oct 26 12:09:20 EDT 2005 ajc
234 * webcit.c: msgesc() no longer inserts backslashes before every single-quote
235 appearing in the quoted or forwarded message.
237 Mon Oct 24 23:10:30 EDT 2005 ajc
238 * Mailbox view: deleting messages now moves them to the Trash folder
240 Mon Oct 24 22:18:25 EDT 2005 ajc
241 * calendar_view.c: fixed a variable initialization bug that was causing some
242 time-specific events to be displayed as all-day events.
244 Mon Oct 24 11:58:53 EDT 2005 ajc
245 * List sub/unsub confirmation -- Citadel now wants http:// or https://
246 prepended as part of the 'submitted subscribe url' so we are now doing
249 Sat Oct 22 01:01:02 EDT 2005 ajc
250 * More changes required to be able to do embedded message/rfc822 and still be
251 able to view the attachments in the embedded submessage. Yow.
252 * Brought over the updated MIME parser from the Citadel package.
254 Fri Oct 21 15:25:49 EDT 2005 ajc
255 * Handle embedded message/rfc822 submessages, using the new form of MSG4 on
256 the Citadel server that can extract these for us. There is still a bug or
257 two in this to be fixed...
259 Mon Oct 17 11:12:50 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
262 Sat Oct 15 00:43:17 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
263 * Sort messages in reverse date order when no sort preference is set
264 * When going from non-date sort to date sort, try reverse order first
266 Sat Oct 15 00:28:35 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
267 * Better handling of multiple recipients in reply-all
269 Thu Oct 13 15:30:08 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
270 * <tr> and </tr> tags for each row in a mailbox summary view, are now
271 output by display_summarized() instead of by readloop(). This makes the
272 code easier to read and refactors it slightly in preparation for some evil
275 Wed Oct 12 23:58:15 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
276 * Rooms view -- render properly when empty floors exist
277 [fixes bugzilla issue # 156]
279 Mon Oct 10 23:01:44 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
280 * Removed an extraneous reference to 'ThreadSSL' in webserver.c that was
281 causing the build to fail on non-SSL systems
283 Sun Oct 9 00:31:33 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
284 * Removed new mail notification from the room banner, and placed it into
285 the Mail button on the iconbar instead. However, this is still broken
286 because the server's new mail notification is insufficient for this...
288 Sun Oct 9 00:12:11 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
289 * serv_crypto.c: don't attempt to continue reading/writing an SSL context
290 that has already been closed. Doing so crashes the webserver, which
291 some people consider a Bad Thing :)
293 Fri Oct 7 23:09:28 EDT 2005 Art Cancro <ajc@uncensored.citadel.org>
294 * Makefile: change "CVS" to ".svn" to avoid errors during make install
296 Fri Oct 7 17:37:16 EDT 2005 ajc
297 * messages.c: fix infinite loop in utf8ify-header
299 Revision 625.34 2005/10/06 19:34:08 ajc
300 * GroupDAV locate_message_by_uid() now uses the EUID command on the Citadel
303 Revision 625.33 2005/10/05 17:54:08 error
304 * Show the ThreadSSL in the debugging logs.
306 Revision 625.32 2005/09/30 20:57:27 ajc
307 * Added "Display Name" (or as vCard calls it, "friendly name" or "fn") to
308 the vCard editing screen.
310 Revision 625.31 2005/09/29 15:59:33 ajc
311 * Finished the "signature" function.
313 Revision 625.30 2005/09/29 04:10:40 ajc
314 * sig is done, but need to add proper handling of linebreaks
316 Revision 625.29 2005/09/29 02:54:17 ajc
317 * Began implementing the "signature" feature. It doesn't work yet.
319 Revision 625.28 2005/09/28 03:29:47 ajc
320 * Don't display room banner on "Confirm move of message" screen
322 Revision 625.27 2005/09/28 03:19:13 ajc
323 * "Reply" and "ReplyAll" now quote the original message, but only when
325 * For non-mail, a "ReplyQuoted" button is now present.
326 * "Move" and "Delete" are now present for a user's mailbox rooms.
327 * Improved the <blockquote> style.
329 Revision 625.26 2005/09/27 02:12:13 ajc
330 * When clicking on an email address in a vCard to send the person an
331 email message, use the display name plus the email address.
333 Revision 625.25 2005/09/26 21:56:31 ajc
334 * Offer the [Move] and [Delete] buttons not only for aide/roomaide, but
335 also whenever we are in a mailbox room owned by the user.
337 Revision 625.24 2005/09/26 18:00:51 ajc
338 * Upgraded TinyMCE to version 2.0RC3. This fixes a conflict with
339 the prototype.js library.
341 Revision 625.23 2005/09/26 03:10:10 ajc
342 * Updated "make install" to handle the multi static thing
344 Revision 625.22 2005/09/26 02:45:06 ajc
345 * Removed the Kevin Roth rich text editor and replaced it with TinyMCE.
347 Revision 625.21 2005/09/25 20:58:56 ajc
348 * Generalized the way we handle static content directories so that we may
349 have more than one of them (i.e. not just "static/")
351 Revision 625.20 2005/09/21 13:25:53 ajc
352 * The RSS/XML button is temporarily commented out in order to prevent
353 users from selecting this possibly unfinished feature.
355 Revision 625.19 2005/09/21 04:00:53 ajc
356 * Downloading attachments now gives the browser a better hint as to what
357 it should name the file.
358 * Downloading attachments is now supported even when the MIME part is
359 stupidly listed as "inline" rather than "attachment."
361 Revision 625.18 2005/09/20 21:59:22 ajc
362 * webcit.c: moved request_method[] out of the global scope (yikes!!!)
363 * rss.c: removed "const" from function declarations to silence
366 Revision 625.17 2005/09/19 02:56:21 ajc
367 * Two-pane mail reading now uses Ajax instead of a hidden iframe, and it's
368 very crisp and responsive.
369 * "Print message" function now opens up a new window for the print
370 preview. I just couldn't figure out a way to keep the b0rken IE from
371 printing the screen instead of the message.
373 Revision 625.16 2005/09/19 02:07:17 ajc
374 * Renamed 'ScriptaculousEffect' back to 'Effect' because there is no
375 longer any namespace conflict.
377 Revision 625.15 2005/09/18 21:47:49 ajc
378 *** empty log message ***
380 Revision 625.14 2005/09/18 16:00:14 ajc
381 * Discovered that Prototype makes it easy to auto-refresh, so I switched
382 the wholist and summary refresh code to use that API instead of doing it
384 * Switched all HTTP/1.0 HTTP/1.1. I don't know if this is going to break
385 anything (it shouldn't -- I'm not knowingly depending upon any features
386 of HTTP/1.0), but it *fixes* the problem of Internet Exploder caching
387 pages even when it's told not to.
389 Revision 625.13 2005/09/18 15:02:29 ajc
390 * summary.c: summary screen is now updated using ajax instead of refreshing
391 the whole page. Not only does this look cleaner, but it also has the
392 happy side effect of not reloading all of the images.
393 * webcit.c: new API calls begin_ajax_response() and end_ajax_response() for
395 * webcit.c: removed the "refresh30" parameter from output_headers() and
396 from all code that calls it. We don't need it anymore; refreshing the
397 entire page is, like, sooooo 2004. :)
399 Revision 625.12 2005/09/18 14:30:05 ajc
400 * Added a "random number" parameter to the wholist ajax refresh request,
401 because b0rken MSIE still insists on fetching from its cache even though
402 it's been explicitly told not to.
404 Revision 625.11 2005/09/18 04:04:32 ajc
405 * Switched the wholist updater to Prototype's AJAX updater, instead of
406 using Rico's wrapper around it. It's actually simpler and doesn't seem
407 to require strict XML, which are both wins.
408 * Removed Rico from the build.
410 Revision 625.10 2005/09/18 03:15:15 ajc
411 * Remove spurious "No new messages" message when viewing an
414 Revision 625.9 2005/09/18 00:53:15 ajc
417 Revision 625.8 2005/09/17 16:44:30 ajc
418 * The JavaScript code to activate the ajax-powered recipient autocompleters
419 has been moved to a function in wclib.js (it's still activated from an
420 inline script in messages.c)
422 Revision 625.7 2005/09/17 13:18:05 ajc
423 * fmt_date.c: changes to "brief" mode. It now displays time-only if the
424 date is today, month/day/time if the date is within the last six months,
425 and date-only for anything older.
427 Revision 625.6 2005/09/17 03:00:06 ajc
428 * Fixed the autocompletion for CC: and BCC:
429 * Moved the autocompletion styles into the stylesheet where they belong
431 Revision 625.5 2005/09/16 04:34:46 ajc
432 * Initial hack of Cc: and Bcc: support
434 Revision 625.4 2005/09/16 02:36:01 ajc
435 * The 'To:' box accepts more characters now
436 * Removed the border from the new 'XML' button
438 Revision 625.3 2005/09/16 01:20:00 error
439 Add Reply and Email links; and an RSS link in the header
441 Revision 625.2 2005/09/15 21:29:42 ajc
442 * Made the message list div slightly larger, the preview pane equally
443 smaller, and stuck a separator bar in between them that will someday
446 Revision 625.1 2005/09/14 03:53:43 ajc
447 * Autocompletion now fetches candidate addresses using the AUTO server
448 command being built for Citadel 6.56
450 Revision 625.0 2005/09/13 14:02:32 ajc
453 Revision 621.41 2005/09/12 20:57:58 ajc
454 * Save/Cancel buttons are now at the top *and* bottom of the message
455 entry screen. Evidently some users seem to want this.
457 Revision 621.40 2005/09/12 19:03:44 ajc
458 * When forwarding a message, properly escape the quoted headers (especially
459 the subject) for insertion into the editor.
461 Revision 621.39 2005/09/12 18:20:21 ajc
462 * The "forward" button is now working, and it forwards the attachments.
464 Revision 621.38 2005/09/12 04:08:05 ajc
465 * Built an initial version of the "forward message" function. It works
466 perfectly on the message text now, but we cannot consider it finished
467 until it also forwards attachments.
469 Revision 621.37 2005/09/10 03:23:05 ajc
470 * Determined where to insert a "Forward" button and the functionality it
471 implements. In order to complete this function we will need a
472 form-sanitized output mode for read_message().
474 Revision 621.36 2005/09/09 19:47:29 ajc
475 * Removed some dead code
477 Revision 621.34 2005/09/09 04:43:22 ajc
478 * Checked in a copy of the "script.aculo.us" library by Thomas Fuchs.
479 NOTE: I had to search-and-replace "Effect" to "ScriptaculousEffect" in
480 all of their files, to avoid a conflict with the name "Effect" in Rico.
481 * Implemented recipient autocompletion when composing mail, using the
482 script.aculo.us drop-down box and an ajax fetch. Cool!!
484 Revision 621.33 2005/09/06 14:44:28 ajc
485 * Altered the logic which determines whether to display a "Post message"
486 or "Send message" button on the message entry screen.
488 Revision 621.32 2005/09/01 03:54:32 ajc
489 * The "prompt for recipient" screen is now gone. When the user is posting
490 from a room requiring a recipient, a "To:" line now appears above the
491 "Subject:" line. Entering an invalid recipient causes the message entry
492 screen to loop back to itself, with the form contents still intact, and
493 the ImportantMessage box set to the error message.
495 Revision 621.31 2005/08/30 04:30:53 ajc
496 * messages.c: teh b0rken Intarweb Exploder was printing the screen rather
497 than the hidden iframe when user selects "Print" message. Applied a
500 Revision 621.30 2005/08/23 02:57:04 ajc
501 * Added some files to the po/ directory, but I really don't know what I'm
504 Revision 621.29 2005/08/22 21:22:00 ajc
505 * vcard_edit.c webcit.c webserver.c who.c : i18n
506 * This should complete the internationalization of the entire WebCit
507 package. Testing must be done, and then of course we must have someone
508 do a translation so we can see if this thing works.
510 Revision 621.28 2005/08/22 20:27:26 ajc
512 * vcard.c: minor change to comments in code
514 Revision 621.27 2005/08/22 20:21:21 ajc
517 Revision 621.26 2005/08/22 19:26:09 ajc
518 * subst.c summary.c sysmsgs.c : i18n
520 Revision 621.25 2005/08/22 19:06:52 ajc
523 Revision 621.24 2005/08/22 18:02:24 ajc
524 * siteconfig.c: began i18n
526 Revision 621.23 2005/08/22 16:53:11 ajc
529 Revision 621.22 2005/08/22 04:33:30 ajc
530 * paging.c preferences.c roomops.c : i18n
531 * Also changed various "OK" buttons to labels more descriptive of
532 their actual functions.
534 Revision 621.21 2005/08/22 01:02:42 ajc
535 * messages.c: finished i18n
536 * webcit.h: minimum required Citadel server version is now 6.55; this is
537 required in order to gain access to the new version of the MSGS command
538 that includes a header summary.
540 Revision 621.20 2005/08/21 05:02:17 ajc
541 * messages.c: renamed some elements
543 Revision 621.19 2005/08/20 04:37:50 ajc
545 * messages.c: partially i18n
547 Revision 621.18 2005/08/19 21:46:48 ajc
548 * inetconf.c, listsub.c, part of mainmenu.c: i18n
550 Revision 621.17 2005/08/19 16:56:00 ajc
551 * inetconf.c: partial i18n
553 Revision 621.16 2005/08/18 22:08:26 ajc
556 Revision 621.15 2005/08/18 18:33:34 ajc
557 * calendar_view.c event.c floors.c graphics.c html2html.c iconbar.c: i18n
559 Revision 621.14 2005/08/18 16:17:25 ajc
560 * calendar_tools.c: i18n
562 Revision 621.13 2005/08/18 14:36:54 ajc
563 * calendar.c: finished preparing strings for i18n
564 * sysmsgs.c: Save/Cancel buttons now have different element names, so we
565 can do a "which element has a nonzero length" check instead of a "what
566 is the value of this element" check. This is vital because the value
567 equals the label, and the label will change if the language changes.
568 This must be done throughout the system.
570 Revision 621.12 2005/08/17 22:18:00 ajc
571 * calendar.c: altered conflict reporting strings for better i18n
573 Revision 621.11 2005/08/17 17:56:32 ajc
574 * availability.c: prepared for i18n
575 * calendar.c: began preparing for i18n
577 Revision 621.10 2005/08/17 17:44:59 ajc
578 * auth.c: prepared for internationalization
580 Revision 621.9 2005/08/17 03:43:20 ajc
581 * More work to get the gettext stuff working, although I really don't
582 know what I'm doing here
584 Revision 621.8 2005/08/16 20:51:08 ajc
585 * More gettext/i18n crap
587 2005-08-16 gettextize <bug-gnu-gettext@gnu.org>
588 * configure.in (AC_OUTPUT): Add intl/Makefile,
590 Revision 621.7 2005/08/16 20:14:25 ajc
591 * This is an attempt to gettextize the WebCit build.
593 Revision 621.6 2005/08/15 16:49:02 ajc
594 * post_mime_to_server() now includes "MIME-Version: 1.0" as required
595 by RCC2045. Some clients look for this. (Thanks to Shayne for this one)
597 Revision 621.5 2005/08/12 21:53:31 ajc
598 * All OS-level includes are now included from webcit.h instead of from
599 each individual .c file. This will keep the build cleaner.
601 Revision 621.4 2005/08/12 01:01:27 ajc
602 * The iconbar and summary screen now connect to the user's primary
603 groupware rooms using the new macros: _CALENDAR_, _TASKS_, _NOTES_,
604 and _CONTACTS_, in order to facilitate those rooms potentially having
605 different names on some hosts (such as, perhaps, the same names but in
606 different languages).
608 Revision 621.3 2005/08/11 23:15:03 ajc
609 * Added debian build directory (submitted by W. Goesgens)
611 Revision 621.2 2005/08/10 21:55:04 ajc
612 * siteconfig.c: added support for "instant expunge" and "allow spoofing"
613 global configuration options.
615 Revision 621.1 2005/08/09 01:13:29 ajc
616 * Mailbox summary view is now generated using the server's
617 new "message list with headers summary" mode.
619 Revision 621.0 2005/08/05 16:28:24 ajc
622 Revision 619.43 2005/08/02 02:38:34 ajc
623 * new iconv check for both libiconv and built-in iconv
625 Revision 619.42 2005/08/01 02:28:55 ajc
626 * Made the ImportantMessage div less obtrusive
628 Revision 619.41 2005/07/29 16:26:04 ajc
629 * omit check for gnu libiconv -- the iconv functionality is built into
630 most operating systems now.
632 Revision 619.40 2005/07/29 04:37:29 ajc
633 * fixed a bug in subject iconv ing
635 Revision 619.39 2005/07/28 04:06:31 ajc
636 * "Print" button on each message. It even uses a hidden iframe to
637 eliminate the "here's the printable view" window; the user goes straight
638 to the browser's print dialog. Slick!
640 Revision 619.38 2005/07/28 03:40:04 ajc
641 * "Delete selected" button is now "Delete" and it works again
643 Revision 619.37 2005/07/28 03:16:30 ajc
644 * Awesome new 2-pane layout with ajax functionality for mailbox view.
645 * Slick new fade-out effect for "important message" boxes.
647 Revision 619.36 2005/07/26 04:08:41 ajc
648 * Previous checkin broke viewing of individual messages while in
649 mailbox summary mode. Fixed.
651 Revision 619.35 2005/07/26 03:46:27 ajc
652 * The new sorting options broke the delete-message checkboxes. Fixed.
653 * Sorting options are now selectable in either direction, and are
654 persistent across sessions.
656 Revision 619.34 2005/07/25 19:22:30 ajc
657 * mailbox summary sort by subject/sender/date
659 Revision 619.33 2005/07/24 04:25:42 ajc
660 * Replaced the old Citadel logo with a new one
661 designed by Lisa Aurigemma (vermilion).
663 Revision 619.32 2005/07/23 04:18:40 ajc
664 * New AJAX-based wholist refresh
666 Revision 619.31 2005/07/22 15:07:29 ajc
667 * 'whobbs' is now 'who'
668 * Refactored the wholist code to have its inner div output by a separate
669 function, in anticipation of possible ajax functionality being added
671 Revision 619.30 2005/07/22 04:03:30 ajc
672 * HTML messages in foreign character sets are now converted to UTF-8 for
675 Revision 619.29 2005/07/22 03:40:22 ajc
676 * Handle display of RFC2047-encoded subjects and senders by converting
677 them to UTF-8 (all WebCit pages are output as UTF-8). Resolves bug #136.
679 Revision 619.28 2005/07/20 04:26:24 ajc
680 * Detect libiconv on the host system and link it in if present.
681 * If libiconv is present, convert foreign charsets to UTF-8 on the fly
682 when outputting text/plain messages. (Still need to do text/html.)
684 Revision 619.27 2005/07/19 17:05:23 ajc
685 * Removed the last couple of places where forms were submitted using
686 the GET method. POST is just so technologically cleaner that we should
688 * Fixed a bug in the MIME parser that was causing it to not be 8-bit
691 Revision 619.26 2005/07/19 14:23:04 ajc
692 * mime_parser.c: don't default Content-type: to text/plain, because when
693 an HTTP POST operation is performed, the content type is expected to
696 Revision 619.25 2005/07/19 04:15:45 ajc
697 * Brought over the newest version of the MIME parser from Citadel,
698 containing an API that supports arbitrary character sets.
700 Revision 619.24 2005/07/14 04:21:53 ajc
701 * More intelligent JavaScript to handle the greying out of end date and
702 start/end times when "all day event" is selected.
704 Revision 619.23 2005/07/14 04:02:18 ajc
705 * Fix bug #147 (date sometimes saved incorrectly for all day events due
706 to timezone differences)
708 Revision 619.22 2005/07/13 16:55:59 ajc
709 * Use the new icons in more places.
711 Revision 619.21 2005/07/13 01:59:20 ajc
712 * Installed the final batch of new icons
714 Revision 619.20 2005/07/12 22:10:52 ajc
717 Revision 619.19 2005/06/29 17:55:32 ajc
718 * Any HTTP method other than GET or POST is now routed directly to the
719 GroupDAV code. This will eventually allow requests such as "PROPFIND /"
721 * GroupDAV requests not beginning with "/groupdav" now automatically have
722 that prefix prepended to them.
724 Revision 619.18 2005/06/29 15:25:00 ajc
725 * Added an experimental OPTIONS method. This is not required by GroupDAV,
726 but it is an experiment to see whether we can use the same code framework
727 to implement other DAV variants in the future.
729 Revision 619.17 2005/06/29 03:12:28 ajc
730 * Bumped internal version number to 6.20
732 Revision 619.16 2005/06/29 03:10:10 ajc
733 * PROPFIND on an individual item inside a room now works (it simply
734 spews the href and etag properties, regardless of what the request
735 was). This is not valid GroupDAV, but Kontact expects this request to
736 succeed before an item can be deleted, so we provide a simple response.
738 Revision 619.15 2005/06/28 14:12:38 ajc
739 * GroupDAV HTTP header "ETag:" is now output as "etag:" in order to deal with
740 a case-sensitivity bug in the Kontact client.
742 Revision 619.14 2005/06/27 22:15:38 ajc
743 * Header file adjustments to make it work on FreeBSD
745 Revision 619.13 2005/06/27 17:38:06 ajc
746 * HTML pages are now output as "Content-type: text/html; charset=utf-8"
747 UTF-8 is going to be the standard character set for the Citadel system.
749 Revision 619.12 2005/06/24 19:58:02 ajc
750 * Added a "preferences and settings" screen for each user.
751 * Removed the javascript date output stuff because it's not granular
752 or international enough.
753 * All dates and times can now be 12 or 24 hours.
755 Revision 619.11 2005/06/24 15:17:48 ajc
756 * The date/time stamp of messages are now output using JavaScript's
757 toLocaleString() function, observing the browser's locale and timezone
758 instead of the web server's.
760 Revision 619.10 2005/06/23 04:01:59 ajc
761 * groupdav_main.c: remove double slashes in path name
762 (suggested by Johannes Schneider)
764 Revision 619.9 2005/06/22 03:04:22 ajc
765 * siteconfig.c: add "auto db log cull" setting now in Citadel 6.52
767 Revision 619.8 2005/06/21 02:27:37 ajc
768 * Moved some JavaScript functions out of head.html and into a new wclib.js
769 file, which can be included and cached. This will form the basis for a
770 new WebCit JavaScript function library.
772 Revision 619.7 2005/06/20 20:38:50 ajc
773 * The main stylesheet is now in a separate file in the static/ directory.
774 Something we did recently must have fixed the caching problem, because it's
775 only being fetched once now (or "now once" if you're Pennsylvania Dutch).
777 Revision 619.6 2005/06/20 03:47:44 ajc
778 * inetconf.c: in save_inetconf(), eliminate sizeof(x) where x is a pointer
779 to a heap-allocated buffer rather than a char[xxx]. This fixes a problem
780 reported by at least one site where the Internet configuration screen
783 Revision 619.5 2005/06/19 04:11:52 ajc
784 * Integrated the second batch of new icons.
786 Revision 619.4 2005/06/18 22:58:56 ajc
787 * Installed the 16x16 "users" icon as favicon.ico, mainly for performance
788 reasons -- the browser will cache favicon.ico and won't keep asking for
789 it over and over again, eliminating a second HTTP transaction every time
790 the user clicks on something.
792 Revision 619.3 2005/06/18 22:48:32 ajc
793 *** empty log message ***
795 Revision 619.2 2005/06/18 22:18:29 ajc
796 * Replaced the most recent batch of icons with a "better" set which was
797 sent by the design house. I don't know what the difference is, but
798 I'm going to assume they're better.
800 Revision 619.1 2005/06/15 03:56:56 ajc
801 * Accept ".ifb" as a valid extension for requesting free/busy
803 Revision 619.0 2005/06/15 01:52:33 ajc
806 Revision 611.15 2005/06/15 01:50:29 ajc
807 * Bumped the internal version number to 6.19
809 Revision 611.14 2005/06/14 14:47:48 ajc
810 * Moved the <td> and </td> in the room icon out of roomops.c and
811 into static/roombanner.html, since every room will have an icon now.
813 Revision 611.13 2005/06/14 03:21:57 ajc
814 * When no icon is present on the server for a room, display the default
815 icon for that room's current view.
816 * Replace "graphic" with "icon" throughout the system messages.
818 Revision 611.12 2005/06/14 01:59:43 ajc
819 * 16x16 icons in the new tree view. Nice!
821 Revision 611.11 2005/06/13 22:05:54 ajc
822 * Finished the initial NanoTree integration. TODO: use a different icon
823 for each node depending on the view set for that room.
825 Revision 611.10 2005/06/12 22:02:45 ajc
826 * Began replacing the old, sux0r-prone tree view with NanoTree.
827 WARNING: This isn't finished, but I'm committing it anyway because I have
828 to move to a different computer. DON'T RUN THIS.
830 Revision 611.9 2005/06/12 18:34:50 ajc
831 * Removed some unreferenced files from the static/ directory.
833 Revision 611.8 2005/06/12 17:01:00 ajc
834 * Increase maximum viewable message count from 4096 to 10000
835 * Summary view now truncates subject to 75 characters, and sender
836 to 25 characters (adding an ellipsis...) to keep the display neat & tidy
838 Revision 611.7 2005/06/12 16:03:11 ajc
839 * When viewing a mailbox (view == VIEW_MAILBOX), messages are marked as
840 seen when they are viewed, and Goto does not automatically mark the
841 remaining messages as seen.
843 Revision 611.6 2005/06/11 22:29:07 ajc
844 * Integrated the first batch of new icons.
846 Revision 611.5 2005/06/07 04:31:00 ajc
847 * Don't compress when HTTP tracing/logging is enabled
849 Revision 611.4 2005/06/06 23:50:17 ajc
850 * Made some changes to the calendar/uuid logic to fix a bug that caused
851 duplicate entries for an event to appear in some situations
853 Revision 611.3 2005/06/06 16:20:36 ajc
854 * GroupDAV URI escape character is now '%' in order to be consistent...
856 Revision 611.2 2005/06/04 04:07:36 ajc
857 * Calendar invitations: changed "Accept/Tentative/Decline" buttons to
858 links in order to avoid them being in nested forms.
860 Revision 611.1 2005/06/02 16:10:08 ajc
861 * tools.c: generated uuid's no longer contain "{" and "}" characters.
863 Revision 611.0 2005/05/26 04:38:09 ajc
866 Revision 610.9 2005/05/26 04:37:59 ajc
867 * Updated internal version number to 6.11
869 Revision 610.8 2005/05/26 04:28:27 ajc
870 * Applied GroupDAV patches sent in by Johannes Schneider which improve the
871 protocol accuracy of xmlns and etag responses.
872 * Fixed a MIME Content-Type bug which I had inadvertently introduced while
873 removing a temporary hack that was put in during KDE 3.4 beta
875 Revision 610.7 2005/05/24 04:26:47 ajc
876 * Applied a patch sent by Johannes Schneider for correcting the XML
877 namespace presented in the PROPFIND command.
879 Revision 610.6 2005/05/23 19:30:34 ajc
880 * Move "enable full text" checkbox configuration to its new location in
881 the configuration back end.
883 Revision 610.5 2005/05/22 16:20:09 ajc
884 * siteconfig.c: add checkbox for enabling full text index on server
886 Revision 610.4 2005/05/11 03:00:03 ajc
887 * webcit.c: fixed a string bug that caused the whole system to not work
888 * messages.c: fullname only and brief date in summary view, so that it
889 doesn't wrap onto two lines quite as often
891 Revision 610.3 2005/04/11 20:09:33 ajc
892 * Began an assault on strcpy()
894 Revision 610.2 2005/04/11 14:45:12 ajc
895 * Replaced serv_gets() with serv_getln() - which now requires the caller
896 to supply the size of the target buffer.
898 Revision 610.1 2005/04/08 19:36:56 ajc
899 * Moved to the new string tokenizer API
901 Revision 610.0 2005/04/04 17:50:04 ajc
902 * THIS IS 6.10 (unfinished first time install wizard has been disabled)
904 Revision 603.15 2005/04/04 17:49:31 ajc
905 * configure.in: fix libical version detection
906 * bumped internal version number to 6.10
908 Revision 603.14 2005/03/30 21:44:44 ajc
909 * Changed the color of the side button bar
910 * Removed session ID's from wholist display, because they are only
911 interesting to computers, not to people.
912 * Also changed the session ID variable (we still need it internally) from
913 a char to an int, because session numbers are big now.
915 Revision 603.13 2005/03/30 17:27:55 ajc
916 * serv_crypto.c: made changes to OpenSSL calls ... removed unnecessary
917 calls and also enabled SSLv3/TLSv1
919 Revision 603.12 2005/03/10 05:13:21 ajc
920 * Created the framework for the "first time setup wizard"
922 Revision 603.11 2005/03/09 04:08:30 ajc
923 * Delete room is now confirmed through a JavaScript popup instead of
925 * New icon for "Tasks." In order to keep it consistent with the rest of
926 the icons, it is ugly.
927 * Modified page popup style slightly.
929 Revision 603.10 2005/03/08 04:59:31 ajc
930 * More attractive display of vCards (hide unknown fields)
931 * Added "title" and "organization" to vCard display/edit
932 * Replaced semicolon with comma-space in vCard name display
934 Revision 603.9 2005/03/07 04:03:28 ajc
935 * auth.c: shrink the margins on the login screen so the user sees something
937 * Allow editing of address book entries wherever possible.
938 * Anything that was a (link) is now a [link]
940 Revision 603.8 2005/03/07 01:45:30 ajc
941 * Rolled back to the old RTE because the new one doesn't work in Safari.
943 Revision 603.7 2005/03/05 22:26:26 ajc
944 * crypto.c: allow use of chained certificates
946 Revision 603.6 2005/03/05 05:04:34 ajc
949 Revision 603.5 2005/03/04 04:21:05 ajc
950 * When a room is set to the "mailbox" view, "Read new / read all" is
951 replaced by "View message list."
953 Revision 603.4 2005/02/28 04:01:55 ajc
954 * Updated to the latest version of Kevin Roth's richtext editor. Had to
955 modify it a bit (removal of 'px' suffix, and addition of 'cols=80') to
956 allow it to gracefully degrade in Konqueror even when we specify our
958 * Modified the message entry screen a bit. Full height just isn't practical
959 with all those wacky browsers out there, unfortunately. Removed most of
962 Revision 603.3 2005/02/23 05:08:20 ajc
963 * Better control of HTTP headers which control browser caches. Static
964 objects are getting properly cached now.
966 Revision 603.2 2005/02/22 05:15:28 ajc
967 * When the "begin_burst() / end_burst()" semantics are in use, perform
968 gzip compression when the client indicates support for it.
970 Revision 603.1 2005/02/21 23:00:04 ajc
971 * begin_burst() / end_burst() semantics now apply to all pages which are
972 output using the "include_html_head" option of output_headers() (which
973 is nearly all of them). This should speed up the network considerably,
974 and also pave the way for another attempt at adding zlib compression
977 Revision 603.0 2005/02/21 22:00:13 ajc
980 Revision 602.10 2005/02/21 21:57:55 ajc
981 * Various debugging type of everythingism to help chat mode to work.
983 Revision 602.9 2005/02/21 04:47:41 ajc
984 * When creating rooms:
985 * 1. Selecting a view other than "Bulletin Board" causes the room access
986 * type to default to "private mailbox"
987 * 2. When the room access type changes to "private mailbox," the floor
988 * selector is greyed out because it is irrelevant.
990 Revision 602.8 2005/02/20 06:48:30 ajc
991 * View-o-matic now has "View as: " before it. "Messages" has been changed
992 to "Bulletin Board" and "Summary" has been changed to "Mailbox Summary"
993 * The View-o-matic is now styled to be smaller and color-matched to the
994 banner box it lives in.
995 * Removed "Summary" from message range selector. It is redundant.
997 Revision 602.7 2005/02/20 06:27:53 ajc
998 * Switched the Reply/Move/Delete buttons back to ordinary links, because
999 the nested forms were causing the bottom part of the outer form to stop
1000 working (message range selector went dead). Thanks to triLcat for
1003 Revision 602.6 2005/02/19 06:01:14 ajc
1004 * The previous <div style=\"margin-right:1px\"> has been replaced by a
1005 named div in the stylesheet. This allows us to perform a vile, sleazy
1006 hack to keep IE6 from exhibiting its horizontal scrollbar bug. There
1007 will unfortunately always be a right margin in IE6, but there
1008 doesn't appear to be any easy workaround.
1010 Revision 602.5 2005/02/19 05:22:00 ajc
1011 * Replaced all the "centered 99% tables" with 100% width tables wrapped
1012 inside a div with margin-right:1px to remove the horizontal scrollbar
1013 in Gecko without creating whitespace. IE6's problem is much more
1014 serious and will require dropping a nuclear bomb on Redmond to fix.
1016 Revision 602.4 2005/02/18 05:09:52 ajc
1017 * Moved the room access control screen into a tab on the edit room menu
1019 Revision 602.3 2005/02/17 04:48:26 ajc
1020 * After setup is complete, tell them how to log in.
1021 * Don't allow the creation of accounts with blank passwords.
1022 * Don't allow users to change to a blank password.
1023 * Fixed the positioning of a few more screens that accidentally got
1024 partially hidden underneath the iconbar.
1025 * Boldfaced the "Password changed." and other prompts.
1026 * Removed the unreadable blue-on-blue links in the calendar day
1027 view. They're redundant anyway, now: "Add new calendar event" and
1028 "month view" are both in the banner bar.
1029 * "New messages / All messages" are now "Read new messages / Read all
1031 * "Save message" button is now "Post message" for public room posts,
1032 and "Send message" for email.
1033 * "Message has been posted" is now "Message has been sent" for email.
1034 * Swapped positions of "Add users" and "Edit users" boxes.
1035 * vCard editor: "Other Internet email addresses" is now "aliases"
1036 * Renamed the "Users" button to "Who is online?"
1038 Revision 602.2 2005/02/16 05:40:31 ajc
1039 * More display fixes
1041 Revision 602.1 2005/02/16 05:22:22 ajc
1042 * inetconf.c: fixed memory management problem that was causing all
1043 the inetconf to get discarded during edit on IBM POWER5
1045 Revision 602.0 2005/02/15 05:23:10 ajc
1048 Revision 601.3 2005/02/15 05:20:44 ajc
1049 * Fixed an HTTP output error for static data which was causing images
1050 to display improperly in Konqueror
1051 * Changed most of the beginbox_nt boxes to centered tables with 99%
1052 width, to avoid the mysterious horizontal scrollbar
1054 Revision 601.2 2005/02/14 04:57:23 ajc
1055 * Started changing some of the top-level tables from 100% width to 99%
1056 width in order to keep the b0rken CSS box-model from displaying a
1057 horizontal scroll bar when it shouldn't. Lose, lose, lose.
1059 Revision 601.1 2005/02/13 04:22:31 ajc
1060 * Network configuration screen: add IMAPS, POP3S, and SMTPS ports
1062 Revision 601.0 2005/02/12 04:23:43 ajc
1065 Revision 528.48 2005/02/11 03:35:57 ajc
1066 * useredit.c: added an "Delete user" button, because it was unintuitive
1067 to tell people "Delete a user by setting their access level to 0"
1069 Revision 528.47 2005/02/09 04:37:32 ajc
1070 * More GroupDAV fixes and tuning.
1072 Revision 528.46 2005/02/07 22:02:00 ajc
1073 * groupdav_propfind.c: output all XML on a single line, with no linebreaks,
1074 and no whitespace between tags. We have discovered that doing otherwise
1075 will break certain clients.
1077 Revision 528.45 2005/02/06 03:59:33 ajc
1078 * Added some HTTP Date: header output
1080 Revision 528.44 2005/02/05 22:58:46 ajc
1081 * All GroupDAV HTTP output is now \r\n instead of \n terminated.
1083 Revision 528.43 2005/02/05 08:36:13 ajc
1084 * Added an everything-buffering thingi so we can do Content-length:
1086 Revision 528.42 2005/02/05 04:16:01 ajc
1087 * Cleanup of new message range view-o-matic
1088 * GroupDAV GET operations now only send the Content-type: and Date:
1089 headers. All the others are irrelevant.
1091 Revision 528.41 2005/02/04 19:19:23 ajc
1092 * Message reading range selection is now a drop-down box.
1094 Revision 528.40 2005/02/04 17:22:18 ajc
1095 * Cleaned up the rcs/cvs Id tags and leading comments at the top of some files
1097 Revision 528.39 2005/02/04 03:43:31 ajc
1098 * fixed the tasks view in the summary screen
1100 Revision 528.38 2005/02/03 05:13:57 ajc
1101 * More tuning for GroupDAV compliance.
1103 Revision 528.37 2005/02/03 04:38:40 ajc
1104 * VTODO components need to be encapsulated inside VCALENDAR components,
1105 just like we do with VEVENT components. There's a bunch of software
1106 (including the beforesave hook on our own Citadel server) that expects
1109 Revision 528.36 2005/02/02 23:25:21 ajc
1110 * Encode GroupDAV uid's using more concise string escaping, because the
1111 old way was making KOrganizer choke.
1113 Revision 528.35 2005/02/02 04:13:36 ajc
1114 * Debugged the GroupDAV service with KOrganizer. It's mostly working now.
1116 Revision 528.34 2005/02/01 23:15:50 ajc
1117 * Completed GroupDAV PUT. Untested.
1119 Revision 528.33 2005/02/01 19:52:29 ajc
1120 * Bumped the internal version number to 6.01
1121 * Set the minimum required Citadel version to 6.40, because we need the
1122 automatic fill-in-missing-uid groupware stuff, and the new ENT0 semantics
1125 Revision 528.32 2005/02/01 15:15:40 ajc
1126 * Better purging of not-logged-in GroupDAV sessions
1128 Revision 528.31 2005/02/01 14:55:12 ajc
1129 * Reworked the PROPFIND xml output based on an example transaction
1130 supplied by Reinhold Kainhofer. Groupware folder enumeration works
1131 properly in Kontact now.
1133 Revision 528.30 2005/02/01 03:49:09 ajc
1134 * Completed "folder list" PROPFIND, now listing all rooms set to a
1135 calendar, tasks, or address view, using the GroupDAV properties.
1137 Revision 528.29 2005/02/01 02:28:32 ajc
1138 * "time(NULL) mod 60" doesn't work for some reason, so it has been removed.
1139 When defaulting a new event date/time to now, set the seconds to zero
1142 Revision 528.28 2005/01/31 23:31:26 ajc
1143 * Initial attempt at GroupDAV PROPFIND for folder enumeration. Hardcoded
1144 to only show the Calendar> room. It kinda-sorta works with KOrganizer.
1146 Revision 528.27 2005/01/31 16:24:47 ajc
1147 * iconbar is now a happy css hovery lightupy div thing
1149 Revision 528.26 2005/01/29 03:59:25 ajc
1150 * Implemented the GroupDAV DELETE method.
1152 Revision 528.25 2005/01/28 05:25:43 ajc
1153 * iconbar no longer uses the beginbox/endbox semantics, but instead lives
1154 directly inside the iconbar div.
1156 Revision 528.24 2005/01/28 05:13:02 ajc
1157 * GroupDAV object URL's are now based on the EUID of a message (which is
1158 derived from the UID of the groupware object itself) instead of the
1159 message number. This was done in order to conform to GroupDAV's
1160 requirement that the URL cannot change after an object is updated.
1161 * The ETag of a GroupDAV object is still the message number, and in fact
1162 doing so meets that requirement perfectly.
1164 Revision 528.23 2005/01/26 18:15:34 ajc
1165 * PROPFIND now outputs fully qualified URL's
1167 Revision 528.22 2005/01/26 18:02:22 ajc
1168 * Initial implementation of GroupDAV PROPFIND
1170 Revision 528.21 2005/01/26 16:28:23 ajc
1171 * Output ETags in double quotes to conform with the new GroupDAV draft.
1172 * Output HTTP Server: header in GroupDAV transactions
1173 * Server: header now displays both WebCit and Citadel versions
1174 * Added groupdav_common_headers() to output HTTP headers common to all
1175 GroupDAV transactions (Connection: close, Server: WebCit, etc.)
1177 Revision 528.20 2005/01/25 19:51:04 ajc
1178 * Accept escaped characters in GroupDAV GET URL's
1180 Revision 528.19 2005/01/25 04:17:20 ajc
1181 * Implemented the Groupdav GET method, more or less in its final form
1182 (still need to fix the room/folder naming semantics)
1184 Revision 528.18 2005/01/25 03:12:27 ajc
1185 * Completed HTTP "Basic" authentication, and a stub function for the
1186 main entry point for GroupDAV functions.
1188 Revision 528.17 2005/01/24 03:37:48 ajc
1189 * Began laying the groundwork for http-authenticated GroupDAV sessions.
1191 Revision 528.16 2005/01/22 22:50:51 ajc
1192 * removed descriptions in non-main menus
1194 Revision 528.15 2005/01/20 21:24:27 ajc
1195 * When viewing a calendar room, the "Read all messages" link in the
1196 room banner has been replaced by "Day view" and "Month view" links.
1197 (I have also imported icons for week and year views, in case we add
1200 Revision 528.14 2005/01/20 16:13:56 ajc
1201 * Added in a bunch of stupid JavaScript to allow the instant message
1202 window to be dismissed.
1204 Revision 528.13 2005/01/20 04:10:41 ajc
1205 * Cleaned up a bunch of unused cruft from the old layout
1206 * Instant messages are now displayed in a div that layers itself
1207 over the rest of the site. It would be nice if we could figure out
1208 a way to make a clickable "hide" box...
1210 Revision 528.12 2005/01/17 04:38:14 ajc
1211 * Navbar is now dynamic, in an attempt to make only the relevant controls
1212 appear on any given page.
1214 Revision 528.11 2005/01/15 07:19:08 ajc
1215 * Removed the fixed pixel width from the tree view room list so it doesn't
1216 wrap around in an ugly way on aIEeeee.
1218 Revision 528.10 2005/01/15 05:26:27 ajc
1219 * Message entry window is now somewhat full screen.
1221 Revision 528.9 2005/01/14 21:03:17 ajc
1222 * A few logging hacks
1224 Revision 528.8 2005/01/14 15:00:51 ajc
1225 * Placed the navbar into the room banner, at least in its temporary form.
1227 Revision 528.7 2005/01/14 04:53:54 ajc
1228 *** empty log message ***
1230 Revision 528.6 2005/01/14 04:53:12 ajc
1231 * Got the three-pane model working not only with web browsers, but also
1232 with the disgusting abomination called Internet Explorer.
1234 Revision 528.5 2005/01/13 18:38:08 ajc
1235 * Insert a newline between </div> and <div id="text">
1237 Revision 528.4 2005/01/11 16:20:18 ajc
1238 * Switching doctype from XHTML to HTML 4.01 STRICT, because nothing handles
1241 Revision 528.3 2005/01/11 05:05:08 ajc
1242 * *** HUGE CHANGES *** *** WARNING: NOT FULLY FUNCTIONAL ***
1243 * Ripped things apart in a big way. The frameset is gone (except for
1244 chat, for which we'll probably keep frames). Iconbar and banner are
1245 now done using CSS and <div> tags.
1246 * Room read/enter/goto controls are currently missing. Stay tuned.
1247 * I am in the process of rewriting all of the markup as valid XHTML.
1249 Revision 528.2 2004/12/29 22:08:08 ajc
1250 * roomops.c: provide a way to create room shares with a mapping to an
1251 alternate room name on the other end.
1253 Revision 528.1 2004/12/29 17:28:09 ajc
1254 * roomops.c: when adding/removing nodes in the 'Sharing' tab, don't go
1255 all corrupty-whatever when a remote room name mapping is found. Display
1256 the mapping and preserve it across share/unshare operations.
1258 Revision 528.0 2004/12/28 03:58:34 ajc
1261 Revision 527.1 2004/12/28 03:58:24 ajc
1262 * Corrected overly-escaped reply-to addresses in "reply" button
1263 * Repaired toggling of self-service account creation in admin screen
1264 * Bumped internal version number to 5.28
1266 Revision 527.0 2004/12/07 04:41:37 ajc
1269 Revision 526.1 2004/12/07 04:41:02 ajc
1270 * Finally tracked down the WC->vars heap corruption issue (for real this
1271 time). We now call clear_local_substs() at the end of each HTTP
1272 transaction, whether we need to or not, instead of calling it whenever
1273 we're done with something we wanted session variables for.
1274 * Finally tracked down the years-long "misplaced '(edit)' link" bug, by
1275 copying serv_info->serv_pid to WC->ctdl_pid at the time it's loaded,
1276 preventing it from getting clobbered by another session.
1277 * Bumped internal version number to 5.27
1279 Revision 526.0 2004/12/01 21:35:56 ajc
1282 Revision 525.4 2004/12/01 21:35:44 ajc
1283 * Changed internal version number to 5.26
1285 Revision 525.3 2004/12/01 21:34:17 ajc
1286 * Numerous memory management bugfixes.
1288 Revision 525.2 2004/12/01 16:48:24 ajc
1289 * tools.c: don't crash when striplt() is called with a zero-length string
1291 Revision 525.1 2004/11/12 18:02:36 ajc
1292 * Updated the richtext editor (new version from Kevin Roth's site)
1294 Revision 525.0 2004/11/03 20:21:10 ajc
1297 Revision 524.7 2004/11/03 20:21:02 ajc
1298 * Changed internal version number to 5.25
1300 Revision 524.6 2004/10/20 02:41:41 ajc
1302 * Added the notes room to the icon bar
1303 * Set up an initial implementation of Notes view. Attractive enough to
1304 publish, but read-only. Needs a note editor.
1306 Revision 524.5 2004/10/15 03:10:24 ajc
1307 * Calendar objects UID now generated by generate_uuid() which creates
1308 pseudo-DCE-ish UUID's.
1310 Revision 524.4 2004/10/05 01:59:31 ajc
1311 * localtime_r() fixes
1313 Revision 524.3 2004/10/03 02:56:35 ajc
1314 * Added a pthread_attr_destroy() in the appropriate place (thanks fleeb!)
1316 Revision 524.2 2004/10/01 16:23:23 ajc
1317 * Set up framework for "notes" view, and added a skeleton function for
1320 Revision 524.1 2004/09/30 03:44:01 ajc
1321 * fix line width break problem in chat
1323 Revision 524.0 2004/09/28 16:12:44 ajc
1326 Revision 523.12 2004/09/28 16:12:30 ajc
1327 * Prepare for 5.24 release
1329 Revision 523.11 2004/09/27 02:17:47 ajc
1330 * messages.c: fix build problem on non-calendar-enabled installations
1331 * floors.c: fix a warning message
1333 Revision 523.10 2004/09/25 03:34:21 ajc
1334 * summary.c: Fixed a calling syntax problem
1336 Revision 523.9 2004/09/25 03:18:43 ajc
1337 * small stylesheet fix
1339 Revision 523.8 2004/09/24 04:21:41 ajc
1340 * Fixed display bug for room list mode when we dropped down multiple
1341 sublevels at once (such as, from 3 to 1 instead of from 2 to 1)
1343 Revision 523.7 2004/09/24 04:08:25 ajc
1344 * Put our <SPAN> tags back in to denote floors, rooms with new msgs, and
1345 rooms without new msgs
1347 Revision 523.6 2004/09/24 04:04:34 ajc
1348 * "folders view" of room list now uses Dave Lindquist's "menuExpandable3"
1351 Revision 523.5 2004/09/23 03:21:10 ajc
1352 * roomops.c: "folders" view of rooms is an actual Unnumbered List now.
1354 Revision 523.4 2004/09/16 02:42:37 ajc
1355 * Set default view of new rooms during CRE8 command instead of afterwards
1357 Revision 523.3 2004/09/15 03:08:50 ajc
1358 * Support config of seaperate MSA port in Citadel 6.26
1360 Revision 523.2 2004/09/10 03:49:17 ajc
1361 * Added 'dialog' mode to setup
1363 Revision 523.1 2004/08/31 20:31:01 ajc
1364 * When saving VTODO (tasks), insert a UID if none is already present. Also
1365 increment the sequence, or insert one if none is already present.
1367 Revision 523.0 2004/08/31 03:02:37 ajc
1370 Revision 522.30 2004/08/31 03:02:28 ajc
1371 * Changed internal version number to 5.23
1373 Revision 522.29 2004/08/27 02:40:06 ajc
1374 * Ditched the graphical buttons because CSS can do the same thing faster.
1376 Revision 522.28 2004/08/18 03:16:12 ajc
1377 * 'move' and 'delete' buttons only show when allowed to do those things
1379 Revision 522.27 2004/08/18 02:10:17 ajc
1380 * Reply/Move/Delete buttons are now images, because system-native buttons
1381 were too big and ugly.
1383 Revision 522.26 2004/08/11 17:24:57 ajc
1384 * static/iconbar.html: removed.
1385 * Updated the "powered by citadel" graphic
1387 Revision 522.25 2004/08/11 03:49:15 ajc
1388 * Replaced all instances of the name "Citadel/UX" with "Citadel"
1389 * Installed the "simple logo" in the iconbar
1391 Revision 522.24 2004/08/09 03:11:20 ajc
1392 * Changed DOCTYPE to HTML 3.2 because that's really what it resembles
1394 Revision 522.23 2004/08/05 21:32:17 ajc
1395 * Reply/Move/Delete are now buttons instead of links. This should enable
1396 us to add some JavaScript magic for "Reply quoted" ...
1398 Revision 522.22 2004/08/05 02:47:21 ajc
1399 * Removed the "pull_quote" style and used the <BLOCKQUOTE> tag instead. It
1400 has a more predictable and attractive behavior, and can still be
1401 overridden in the style sheet if the site operator wants to.
1403 Revision 522.21 2004/08/04 03:52:23 ajc
1404 * Tasks view is now pretty.
1405 * Tasks view now displays date due for each task.
1406 * Tasks view is now sorted by date due.
1407 * Tasks view now displays overdue tasks in red.
1409 Revision 522.20 2004/08/03 03:55:37 ajc
1410 * Tasks view now uses the same buffer/dump logic as the calendar views, so
1411 we can sort them by due date and do a prettier display. (Only the logic is
1412 changed so far. The prettier display is forthcoming.)
1414 Revision 522.19 2004/07/21 02:57:09 ajc
1415 * Internet Configuration screen looks a little neater now
1417 Revision 522.18 2004/07/21 02:45:15 ajc
1418 * Completed the "Internet Configuration" screen
1420 Revision 522.17 2004/07/16 19:13:37 ajc
1421 *** empty log message ***
1423 Revision 522.16 2004/07/16 19:13:10 ajc
1424 * tools.c: display 12:00 as 12pm, not 12am
1426 Revision 522.15 2004/07/16 03:14:03 ajc
1427 * more work on inetconf screen
1429 Revision 522.14 2004/07/16 02:50:00 ajc
1430 * useredit.c: put a pretty box around user editing
1432 Revision 522.13 2004/07/13 03:25:08 ajc
1433 * inetconf.c: added. Not finished yet.
1435 Revision 522.12 2004/07/10 03:10:19 ajc
1436 * Completed web screens for THE DREADED AUTO-PURGER by adding room and
1437 floor level configurations.
1438 * Put a space between OK and CANCEL buttons anywhere in the system where
1440 * Some more of the room config/admin screens now return to themselves
1441 with a "ok, you did that" message when OK is pressed, instead of dropping
1442 out to the main menu.
1444 Revision 522.11 2004/07/08 03:03:01 ajc
1445 * Added global settings for THE DREADED AUTO-PURGER to the site-wide
1446 configuration (public rooms default and mailboxes default). Still need
1447 to add floor and room policy screens.
1449 Revision 522.10 2004/07/02 03:28:08 ajc
1450 * Much-improved alphabet tabs for Address Book view. Now divides the
1451 total number of names by (names per page, currently 60) and sets up
1452 that many tabs, with proper [Aaa-Bbb] labels on them.
1454 Revision 522.9 2004/07/02 03:26:06 ajc
1455 *** empty log message ***
1457 Revision 522.8 2004/07/01 02:40:40 ajc
1458 * Clicking "Enter a message" in a groupware room now automatically calls
1459 the correct editor for the type of objects in the room (message, calendar
1460 event, task, address book entry)
1462 Revision 522.7 2004/06/29 17:21:25 ajc
1463 * Removed the word "room" in a few locations, as part of our push towards
1464 not looking like a BBS when running in groupware mode
1466 Revision 522.6 2004/06/29 00:37:02 ajc
1467 * Made some fonts bigger because users were complaining...
1469 Revision 522.5 2004/06/27 03:02:05 ajc
1470 * Summary view -- always view ALL messages
1471 * Summary view -- new messages are in boldface
1473 Revision 522.4 2004/06/24 20:42:14 ajc
1474 * Added the "server ip address" Citadel config option
1475 * Site config: added "Changes will not take effect until..." language
1478 Revision 522.3 2004/06/24 14:50:35 ajc
1479 * Added the ability to listen on a single IP address instead of all addresses.
1481 Revision 522.2 2004/06/22 02:21:56 ajc
1484 Revision 522.1 2004/06/21 15:00:52 ajc
1487 Revision 522.0 2004/06/19 03:21:35 ajc
1490 Revision 521.10 2004/06/19 03:11:07 ajc
1491 * Instead of a crufty "the topmost Internet email address will be used
1492 for outgoing email" explanation, separated it into "Primary Internet
1493 email address" and "Other email addresses" boxes.
1495 Revision 521.9 2004/06/19 02:42:12 ajc
1496 * Removed the "aides access to mailboxes" config option, which is no longer
1497 part of the Citadel system.
1499 Revision 521.8 2004/06/16 02:07:22 ajc
1500 * Removed a couple of lines of debugging code leftover from last night
1502 Revision 521.7 2004/06/15 03:06:11 ajc
1503 * Bumped internal version number to 5.22
1504 * Use new fast headers-only-no-mime fetch mode in Citadel for
1507 Revision 521.6 2004/06/15 02:30:21 ajc
1508 * Honor "maxmsgs" even when viewing a mailbox in summary mode
1510 Revision 521.5 2004/06/12 04:26:38 ajc
1511 * Fixed some garbled output resulting from turning things that look like
1514 Revision 521.4 2004/06/11 16:09:36 ajc
1515 * Moved the room graphic to the left of the room name in the banner, to
1516 make it more consistent with the rest of the site.
1517 * Reduced the size of the font in the iconbar
1519 Revision 521.3 2004/06/11 03:15:08 ajc
1520 * When "Add" is clicked without specifying an upload filename, resume
1521 composition instead of aborting the post.
1522 * Add attachments to messages in forward order, not reverse order
1524 Revision 521.2 2004/06/10 03:08:48 ajc
1525 * Improved the appearance of tabs in the room config screen
1527 Revision 521.1 2004/06/10 02:58:55 ajc
1528 * Made all the title boxes the same background color. The old scheme was
1529 cute but not professional looking.
1531 Revision 521.0 2004/06/06 19:53:25 ajc
1534 Revision 510.15 2004/06/06 19:32:15 ajc
1535 * Cleaned up a couple of FIXME's sitting around in the code
1536 * Altered the conditions under which stray http://... strings are
1537 automatically turned into links, to prevent that logic from
1538 transforming IMG tags into gibberish.
1539 * Set internal version number to 5.21
1541 Revision 510.14 2004/06/04 02:29:07 ajc
1542 * Fixed bug in "validate new users" screen (thanks Campy)
1544 Revision 510.13 2004/06/03 03:21:22 ajc
1545 * "Reply" button now carries the message subject into the reply.
1547 Revision 510.12 2004/06/02 02:07:54 ajc
1548 * setup.c: updated the setup script to configure two /etc/inittab entries,
1549 one for http and one for https.
1551 Revision 510.11 2004/06/01 21:46:47 ajc
1552 * crypto.c: when an SSL connection errors out (and closes) unexpectedly
1553 during a read or write operation, do not attempt to finish the operation
1554 unencrypted like we do in Citadel. Here in WebCit land it only causes
1555 the server to segfault.
1557 Revision 510.10 2004/06/01 19:01:22 ajc
1558 * netconf.c: widened some of the text entry fields
1559 * webcit.h: bumped up the internal version number to 5.20
1561 Revision 510.9 2004/06/01 18:44:20 ajc
1562 * Return to the old command-line usage (-s for https, service is either
1563 http or https but not both)
1565 Revision 510.8 2004/06/01 03:32:28 ajc
1566 * Add "permanent room" setting to room edit screen
1567 * create room -- allow longer strings
1569 Revision 510.7 2004/06/01 00:36:43 ajc
1570 * Hmmph. Do the session cookie as hex instead of base64. There really
1571 are some characters in the base64 set that make HTTP do nasty things.
1573 Revision 510.6 2004/05/31 21:43:27 ajc
1574 * Added "|END" to the session cookie before base64-ing it. This fixes a
1575 problem with certain room names causing the webserver to freak out and
1576 break embedded images and stuff. I don't know why.
1578 Revision 510.5 2004/05/31 20:34:11 ajc
1579 * Message entry using Kevin Roth's excellent cross-platform richtext
1582 Revision 510.4 2004/05/31 15:54:13 ajc
1583 * "text" and "HTML" options for message entry.
1585 Revision 510.3 2004/05/29 03:31:48 ajc
1586 * tighten up the space between icons in the iconbar
1588 Revision 510.2 2004/05/28 20:24:53 ajc
1591 Revision 510.1 2004/05/24 03:02:38 ajc
1592 * CSS change to make folder names stand out more in the "Folder View"
1594 Revision 510.0 2004/04/30 04:08:58 ajc
1597 Revision 506.13 2004/04/30 04:08:47 ajc
1598 * Changed internal version number to 5.10
1599 * Updated documentation for the new HTTPS service
1601 Revision 506.12 2004/04/27 03:21:36 ajc
1602 * Prompt for HTTPS port number during setup. We may make this optional.
1604 Revision 506.11 2004/04/27 03:16:31 ajc
1605 * When running on the same host as Citadel, if no key/cert are found,
1606 symlink to Citadel's if possible.
1607 * One server binary now forks to start both http and https servers.
1609 Revision 506.10 2004/04/21 03:43:39 ajc
1610 * Completed remaining SSL fixes. Works in Moz, aIEeee, Konq; self-signed
1611 certs are also no longer invalid.
1613 Revision 506.9 2004/04/21 02:25:13 ajc
1614 * Replaced ctdl_install_certificate() with convenience functions found
1615 in the OpenSSL library.
1617 Revision 506.8 2004/04/21 02:19:41 ajc
1618 * Got HTTPS to work with Mozilla (by twiddling stuff that I still don't
1619 understand, but read at http://www.informit.com/articles/article.asp?p=22078
1620 ). Still doesn't work with Internet Monopolizer, though.
1622 Revision 506.7 2004/04/20 02:32:44 ajc
1623 * Allow setup to run seamlessly from within the Citadel Ridiculously
1624 Easy Installer by observing the values of environment variables
1625 CITADEL_INSTALLER, CITADEL, and WEBCIT.
1627 Revision 506.6 2004/04/20 02:02:50 ajc
1630 Revision 506.5 2004/04/16 03:14:06 ajc
1631 * Minor fix for previous checkin
1633 Revision 506.4 2004/04/16 02:59:01 ajc
1634 * Completed SSL support. Still doesn't work with all browsers... gotta
1637 Revision 506.3 2004/04/15 03:57:00 ajc
1638 * Brought over the SSL/TLS stuff from Citadel. I think it's complete but
1639 it has a crashy crashy bug in it. Don't use it yet.
1641 Revision 506.2 2004/04/13 19:41:36 ajc
1642 * GET /freebusy/user.vcf *and* /freebusy/user.vfb now both work.
1643 (freebusy data fetch for anonymous Kolab type clients)
1645 Revision 506.1 2004/04/10 04:32:59 ajc
1646 * Fixed some version and copyright date oopses
1648 Revision 506.0 2004/04/10 04:29:30 ajc
1651 Revision 505.22 2004/04/10 04:29:20 ajc
1652 * Changed internal version number to 5.06
1654 Revision 505.21 2004/03/29 04:30:20 ajc
1655 * configure.in, Makefile.in: handle $LDFLAGS
1657 Revision 505.20 2004/03/20 05:03:14 ajc
1658 * Original startup thread becomes a worker thread after initialization.
1659 Doing otherwise turns it into a zombie (at least on Linux) and possibly
1660 leads to other problems
1661 * Filter out NOOP's received in chat
1663 Revision 505.19 2004/03/18 04:32:24 ajc
1664 * Removed the language in README.TXT which told everyone that chat wouldn't
1665 work with a non-local Citadel server, because that's no longer true.
1666 * Removed the old chat applet from the static/ directory
1668 Revision 505.18 2004/03/18 04:00:44 ajc
1669 * Rounded web boxes now look correct in all browsers.
1671 Revision 505.17 2004/03/17 18:25:31 ajc
1672 * When creating a new user, auto-chain to the "edit user configuration"
1673 screen, and subsequently auto-chain to the "edit address book entry"
1674 screen. This creates a nice sensible workflow.
1676 Revision 505.16 2004/03/15 22:47:09 ajc
1677 * Prettied up the chat window a little more.
1679 Revision 505.15 2004/03/15 04:27:44 ajc
1680 * Chat now appears in a separate window
1681 * Use regular frames instead of IFRAMEs for chat
1682 * Display user's own chat text in bold+italic
1683 * Added a "List Users" button
1685 Revision 505.14 2004/03/09 20:45:45 error
1686 * Add a Linux Software Map file
1688 Revision 505.13 2004/03/07 22:04:32 ajc
1689 * Fix the current view not being set to the default view for the creator
1692 Revision 505.12 2004/03/07 21:31:17 ajc
1693 * serv_read() now zeroes out the supplied buffer (with the supplied
1694 length) if a server read fails. This causes serv_gets() to return
1695 instead of looping endlessly. Fixes chat problem found on linux-ppc.
1697 Revision 505.11 2004/03/03 05:21:36 ajc
1698 * Made the chat screen totally kick-ass sweet. The flickering reload
1699 i-frame is now tiny and hidden, and it *appends* new chat data to
1700 the viewable window using JavaScript. No flickering + scrollback!
1701 * Added a help button to the chat screen.
1703 Revision 505.10 2004/02/29 22:52:15 ajc
1704 * Close and clear (set to -1) server socket handle when socket errors are
1705 detected. Fixes a chat problem reported by Winzlo.
1707 Revision 505.9 2004/02/29 05:34:25 ajc
1708 * Display the Chat menu option as "Chat with other users in <roomname>"
1710 Revision 505.8 2004/02/27 05:04:38 ajc
1711 * fix frameset bug in page popups
1713 Revision 505.7 2004/02/26 04:08:56 ajc
1714 * Fixed a problem that made WebCit go to the "no cookies" screen instead
1715 of the logout banner.
1716 * Ford's latest stupid room has a name with more than 64 characters, and
1717 we still had a 64-byte room name in the march_list struct. ooooops...
1719 Revision 505.6 2004/02/26 03:07:26 ajc
1720 * Put the /favicon.ico --> /static/favicon.ico hack back in. Why not?
1722 Revision 505.5 2004/02/25 23:10:28 ajc
1723 * Allow "/do_logout" as a no-frames page
1725 Revision 505.4 2004/02/25 23:00:21 ajc
1726 * Changed the favicon support to LINK tags in the HEAD of static stuff,
1727 to make life easier. (Thanks to prosthetik for this)
1729 Revision 505.3 2004/02/25 15:20:11 ajc
1730 * Support for favicon.ico in the static/ directory
1732 Revision 505.2 2004/02/24 04:06:42 ajc
1733 * Changed the colors slightly in chat screen
1735 Revision 505.1 2004/02/20 06:07:06 ajc
1736 * Replaced the Java chat with a new system based on IFRAME's and JavaScript
1738 Revision 505.0 2004/02/19 03:32:50 ajc
1741 Revision 504.7 2004/02/19 03:32:38 ajc
1742 * Changed the internal version number to 5.05
1743 * Completed the frames fix
1745 Revision 504.6 2004/02/18 20:08:29 ajc
1746 * Fixed the frameset force reload logic. Now it does the whole frameset
1747 without displaying an error in the main frame.
1749 Revision 504.5 2004/02/18 19:17:51 ajc
1750 * Force reload of frameset if someone tries to escape it. Not perfect
1751 but it mostly works at this poing.
1753 Revision 504.4 2004/02/17 03:37:11 ajc
1754 * Indicate to Citadel that we want Server Generated Invitations when
1755 calendar events are saved. (No longer the default in Citadel server.)
1757 Revision 504.3 2004/02/09 04:49:32 ajc
1758 * Prepare for a way to avoid falling out of the main frameset
1760 Revision 504.2 2004/02/09 03:37:57 ajc
1761 * Changed the thread pool management algorithm. Detecting idle time between
1762 socket accepts was not working reliably on all systems, so we now follow
1763 the same algorithm as the Citadel server (spawn more threads when number
1764 of sessions < number of threads, but keep constrained to pre-defined
1765 minimum and maximum thread count)
1767 Revision 504.1 2004/02/03 03:09:51 ajc
1770 Revision 503.0 2004/01/28 04:31:31 ajc
1773 Revision 502.4 2004/01/28 04:30:48 ajc

1777 * Add 'base DN' and 'bind DN' and 'bind DN password' to siteconfig
1778 * Split the config for LDAP Connector into its own panel
1780 Revision 502.2 2004/01/17 04:32:54 ajc
1781 * Add site config options for Citadel servers which support LDAP
1783 Revision 502.1 2003/10/24 02:50:19 ajc
1784 * Clicking "Enter Message" in a room with an Address Book view opens
1785 a blank vCard entry screen.
1787 Revision 502.0 2003/10/23 03:16:50 ajc
1790 Revision 501.2 2003/10/23 03:07:54 ajc
1791 * event.c: Found and removed another unquoted multi-line string literal
1792 * webcit.h: changed an #ifdef HAVE_ICAL_H
1793 to #ifdef WEBCIT_WITH_CALENDAR_SERVICE to avoid false positives
1795 Revision 501.1 2003/10/22 01:42:12 ajc
1796 * iconbar.c: removed a stray character or two...
1798 Revision 501.0 2003/10/21 04:26:37 ajc
1801 Revision 500.30 2003/10/21 04:26:27 ajc
1802 * bumped the version string to 5.01
1804 Revision 500.29 2003/10/17 03:08:28 ajc
1805 * Finished prettying up the vCard display
1807 Revision 500.28 2003/10/17 02:31:45 ajc
1808 * Multi-line string literals are deprecated in GCC 3.1 unless each line
1809 is wrapped in quotes. Performed this fix so it'll compile.
1810 * setup.c: removed references to unused variable tempfile[]
1812 Revision 500.27 2003/10/09 03:17:02 ajc
1813 * Started prettying up the vCard display.
1815 Revision 500.26 2003/10/08 02:33:49 ajc
1816 * Begin work on better handling of vCard display
1818 Revision 500.25 2003/09/04 03:41:27 ajc
1819 * siteconfig.c: changed some config items to drop-down boxes
1821 Revision 500.24 2003/08/27 04:26:54 ajc
1822 * Split the site configuration screen up into four different screens,
1823 and added a meta-menu
1825 Revision 500.23 2003/08/24 03:31:50 ajc
1826 * Finished the setup program
1827 * Bumped the internal version number to 5.01
1829 Revision 500.22 2003/08/22 00:47:27 ajc
1830 * setup is now working, but it still needs a way to detect a running WebCit
1832 Revision 500.21 2003/08/22 00:25:40 ajc
1833 * Added a skeleton "setup" program to the tree. It does not work yet.
1835 Revision 500.20 2003/08/20 03:48:55 ajc
1836 * Added iconbar shortcut to Contacts room
1837 * Minimum required Citadel is now 6.11
1839 Revision 500.19 2003/08/20 03:07:25 ajc
1840 * Address book "single card" view now suppresses "reading nn message" and
1841 instead shows the letter indices across the top
1842 * Clicking on an address in a vCard now connects to WebCit mail instead
1843 of a browser mailto: link
1845 Revision 500.18 2003/08/19 04:18:43 ajc
1846 * Changed things around in the address book view. Made it sorted and
1847 more clickable and better looking...
1849 Revision 500.17 2003/08/12 18:54:03 error
1850 * messages.c: fix off-by-one-error in selector bar
1852 Revision 500.16 2003/08/07 22:18:03 ajc
1853 * Add the Summary Page to the customizable iconbar
1855 Revision 500.15 2003/08/07 03:51:51 ajc
1856 * Customizable icon bar as: pictures and text, pictures, text
1858 Revision 500.14 2003/08/05 03:52:14 ajc
1859 * First working version of the customizable iconbar. It contains a basic
1860 set of options and now automatically refreshes when it's customized.
1862 Revision 500.13 2003/08/04 03:50:29 ajc
1863 * First cut at the customizable iconbar is done. A bunch of generic options
1864 are there. Still need to get the actual iconbar to refresh when changes
1867 Revision 500.12 2003/08/03 21:02:01 ajc
1868 * More work on customizable iconbar
1870 Revision 500.11 2003/08/02 05:25:46 ajc
1871 * Laid the groundwork for a customizable iconbar
1873 Revision 500.10 2003/07/30 03:57:49 ajc
1874 * Add config.c_purge_hour to config screen
1876 Revision 500.9 2003/07/06 22:06:59 ajc
1877 * When converting "anything that looks like a URL" to a real link, first
1878 make sure that it isn't already inside a link. This fixes most of the
1879 long, ugly URL strings sent by eBay.
1880 * Automatically dismantle mailto: links in HTML messages, and convert
1881 them to WebCit mail links (clicking on it sends the user to the Mail
1882 room and begins composing a new message with the recipient and subject
1883 fields pre-populated).
1885 Revision 500.8 2003/06/29 20:51:21 ajc
1886 * Worked around a rendering bug in Satan's Browser that was causing it
1887 to draw the calendar month view much wider than the actual screen wdith
1889 Revision 500.7 2003/06/28 04:09:37 error
1890 * roomops.c: Backout change to display one less box in the first column in
1891 roomlist view, it doesn't seem to work for everyone
1893 Revision 500.6 2003/06/28 03:52:51 error
1894 * Don't tell browsers not to cache static documents
1896 Revision 500.5 2003/06/28 03:35:23 error
1897 * roomops.c: Display one less floor in the first column in romlist view
1899 Revision 500.4 2003/06/26 03:37:58 ajc
1900 * Allow anonymous HTTP requests for /freebusy/user%20name.vcf (or .vfb)
1901 This will allow some groupware clients to browse the free/busy times of
1902 other users on the system.
1904 Revision 500.3 2003/06/21 05:17:21 ajc
1905 * Better alignment of system messages
1906 * Exterminated display_error() and replaced it with WC->ImportantMessage
1907 which is displayed in a bubble on top of whatever page you're on next.
1908 * Small cosmetic changes
1909 * Fixed some nesting problems in output_headers()
1911 Revision 500.2 2003/06/20 03:39:27 ajc
1912 * Optimization to floor layout in box view
1914 Revision 500.1 2003/06/20 03:04:26 ajc
1915 * "Reply" button on messages now handles IGnet recipients correctly
1917 Revision 500.0 2003/06/10 04:23:08 ajc
1920 Revision 410.50 2003/06/10 04:22:58 ajc
1921 * Updated docs and headers for 5.00 release
1923 Revision 410.49 2003/06/10 04:05:23 ajc
1924 * De-tabled the left side icon bar and reduced one of the graphics, so
1925 that all of the rounded corners show up in Satan's Browser.
1927 Revision 410.48 2003/06/10 03:47:41 ajc
1928 * style.css: added font selection to default <BODY> tag
1930 Revision 410.47 2003/06/06 03:26:03 ajc
1931 * Satan's Browser insists on putting bloody acres of whitespace to the
1932 right of any bulleted list items, making any multi-column table containing
1933 a list take more than the entire screen. Removed all such lists so it
1934 looks ok. If you are reading this and you are a Microsoft employee, please
1935 commit suicide before you break anything else.
1937 Revision 410.46 2003/06/06 02:22:07 ajc
1938 * Changed the upper left and upper right bounded box corners to a solid
1939 blue (#204B78) instead of gradiated, because it was looking funny in
1940 256-color mode. It also looked funny in Internet Explorer, but people
1941 who use Internet Explorer are contributing to terrorism and really don't
1942 deserve Web access in the first place. So I really just fixed this to make
1943 it look good in 256-color Netscape.
1945 Revision 410.45 2003/06/05 21:37:37 ajc
1946 * Cosmetic changes. Attempting to fix b0rken rendering of main menu
1947 in b0rken IE browser. Die, Bill, Die.
1949 Revision 410.44 2003/06/05 03:52:29 ajc
1950 * Buncha cosmetic changes
1952 Revision 410.43 2003/06/04 03:41:25 ajc
1953 * Change the appearance of rooms with and without new messages in the
1954 room list -- now defined using CSS
1956 Revision 410.42 2003/06/03 03:57:42 ajc
1957 * Tightened up the room banner a bit. Smaller padding, smaller font,
1960 Revision 410.41 2003/05/31 21:36:45 ajc
1963 Revision 410.40 2003/05/26 21:05:42 ajc
1964 * availability.c: brought over ical_ctdl_is_overlap() from Citadel. Used
1965 it to complete the free/busy checking for attendee availability.
1967 Revision 410.39 2003/05/26 05:44:45 ajc
1968 * event.c: fix compiler warning
1970 Revision 410.38 2003/05/26 05:39:46 ajc
1971 * webcit.h: change minimum required Citadel server to 6.07 due to FREEBUSY
1972 bug fixed in Citadel.
1974 Revision 410.37 2003/05/26 05:28:13 ajc
1975 * serv_func.c: added utility function read_server_text()
1976 * availability.c: banged out more of this code -- still not complete
1978 Revision 410.36 2003/05/26 03:28:02 ajc
1979 * Getting closer to doing the availability check. Created new source
1980 module 'availability.c' for this purpose. Stub function is in place.
1982 Revision 410.35 2003/05/25 04:25:12 ajc
1983 * siteconfig.c: fixed a spelling error
1984 * event.c: add a "Check attendee availability" button, and the code to
1985 bypass saving the event to the server, do something with it, and then
1986 feed the twiddled data structure back to the form display function for
1987 further editing. What's still missing is the code to do the actual
1990 Revision 410.34 2003/05/24 22:22:35 ajc
1991 * Small stylesheet hack to make it work with b0rken IE
1993 Revision 410.33 2003/05/24 22:13:08 ajc
1994 * Changed the login banner a bit
1996 Revision 410.32 2003/05/20 03:25:41 ajc
1997 * Separate event invitees with newlines instead of commas.
1999 Revision 410.31 2003/05/19 19:55:09 ajc
2000 * summary.c: eliminate compiler warnings about unused variables when
2001 compiling a WebCit service without calendar support
2003 Revision 410.30 2003/05/18 02:05:33 ajc
2004 * More conversion of screens to the new look-and-feel.
2006 Revision 410.29 2003/05/16 04:11:29 ajc
2007 * We don't need no steenking workaround. Problem fixed. MIME parser not
2008 broken. Web server was calling it with bad parameters. All fixed now.
2009 * Slightly tweaked the look of the tabs in the room edit screen. Still looks
2012 Revision 410.28 2003/05/15 04:52:26 ajc
2013 * Minor workaround in web forms to handle mime parser problem in uploads
2015 Revision 410.27 2003/05/15 03:35:59 ajc
2016 * look and feel overhaul -- almost done!
2018 Revision 410.26 2003/05/14 03:46:35 ajc
2019 * More background cleanup
2021 Revision 410.25 2003/05/05 17:19:46 ajc
2022 * Cleanups to summary page when running on a non ical enabled system
2023 * Use non breaking spaces in summary page box titles
2025 Revision 410.24 2003/05/04 04:22:41 ajc
2026 * Display body of messages on a white background. I am doing this in order
2027 to prepare for making the general background of the screen a darker color.
2029 Revision 410.23 2003/05/04 02:54:55 ajc
2030 * Summary page now uses our cutesy new rounded window boxes
2032 Revision 410.22 2003/05/03 21:28:41 ajc
2033 * Added in a slick new box style and put the room lists in it
2035 Revision 410.21 2003/05/03 16:57:04 ajc
2036 * In the 'folders' and 'portal' views, change the folder delimiter
2037 from / to \ to avoid conflict with room names that have slashes
2039 Revision 410.20 2003/05/03 16:23:29 ajc
2040 * Enforce three columns in portal view of room list
2042 Revision 410.19 2003/05/03 04:52:32 ajc
2043 * Added an experimental new "portal view" to the room list options
2045 Revision 410.18 2003/05/02 03:23:41 ajc
2046 * Minor change to room list algorithm
2048 Revision 410.17 2003/05/01 15:33:05 ajc
2049 * Fixed a potential memory leak in enumeration of MIME parts
2051 Revision 410.16 2003/05/01 03:11:35 ajc
2052 * When static content is requested, fetch it without trying to connect
2055 Revision 410.15 2003/04/30 05:00:00 ajc
2056 * Added the ability to compose messages with file attachments uploaded from
2059 Revision 410.14 2003/04/27 04:46:02 ajc
2060 * Replace LKRN/LKRO in "folders view" room list with a single LKRA that
2061 observes the flag designating the presence of new messages. (The "rooms
2062 view" uses an LKRN/LKRO pair *per floor* and has the same inefficiency,
2063 but that view may get axed soon.)
2065 Revision 410.13 2003/04/26 21:57:53 ajc
2066 * tcp_sockets.c: when an outgoing socket connection fails, close the socket
2067 before returning an error code to avoid a file descriptor leak
2069 Revision 410.12 2003/04/19 21:42:36 ajc
2070 * Repaired all my b0rken COLOR tags
2071 * Replaced most FONT tags with SPAN tags
2074 Revision 410.11 2003/04/19 19:58:10 ajc
2075 * Lots of great changes from Nick to make the site CSS-enabled.
2077 Revision 410.10 2003/04/14 04:04:40 ajc
2078 * First cut of CSS-izing WebCit. Probably b0rken.
2080 Revision 410.9 2003/04/09 04:02:32 ajc
2081 * Remove the defaulthost/defaultport vs. c_host/c_port stuff -- we haven't
2082 supported the idea of one WebCit connecting to multiple Citadels for a
2083 long time. Now it's just one set of variables, called ctdlhost/ctdlport.
2084 * When connecting to Citadel through a Unix domain socket, don't try to make
2085 the Java chat applet available.
2087 Revision 410.8 2003/03/31 03:32:19 ajc
2088 * messages.c: check for 000 terminator while parsing RFC822 headers to
2089 prevent getting hung up while displaying certain badly formatted messages.
2091 Revision 410.7 2003/03/30 06:13:19 ajc
2092 * When reading from the server, do not treat CR as end-of-line because
2093 there's probably an LF coming after it. Instead, keep reading to the LF
2094 and then strip both.
2095 * Do not underline links in the icon bars
2097 Revision 410.6 2003/03/17 04:17:41 ajc
2098 * Call to accept() was being made with an uninitialized variable for the
2099 third argument. Changed the second and third argument to NULL and 0 because
2100 we don't really need accept() to fill up a buffer full of information that
2101 we'll never use. (Thanks to SteveV for reporting the bug and helping to
2103 * Removed the mutex wrapper around select() because we don't need it. All
2104 idle worker threads now block on select() and one of them will wake up when
2105 a connection arrives.
2107 Revision 410.5 2003/03/15 20:55:03 ajc
2108 * When a requested image is not available on the Citadel server, send a
2109 1x1 transparent GIF instead of 404 error.
2111 Revision 410.4 2003/03/14 04:21:57 ajc
2112 * clone events to be encapsulated before saving, because the original
2113 instance may already have a parent, and that makes crashy crashy
2115 Revision 410.3 2003/03/13 05:57:17 ajc
2116 * More encapsulation. Warning: there are bugs in this!!
2118 Revision 410.2 2003/03/13 05:20:23 ajc
2119 * Various changes to the calendar service to handle messages containing
2120 fully encapsulated VCALENDAR components instead of only unencapsulated
2121 VEVENT subcomponents. We have to move in this direction for compatibility
2122 with other products.
2124 Revision 410.1 2003/03/01 22:07:19 ajc
2125 * New user registration, as well as existing user re-registration, now
2126 uses the vCard editing screen.
2127 * Administratively editing users' address book entries now works again,
2128 mainly due to a fix in the Citadel server. Now requiring Citadel 6.06
2129 in order to enforce this.
2131 Revision 410.0 2003/02/19 03:49:33 ajc
2134 Revision 400.90 2003/02/19 03:49:17 ajc
2135 * latest config.guess and config.sub from www.gnu.org
2137 Revision 400.89 2003/02/07 04:44:17 ajc
2138 * Replaced sleep() with a function that sleeps using select() in order to
2139 avoid potential issues with SIGALRM. Possible fix for weird behavior
2140 when running on a Macintosh.
2142 Revision 400.88 2003/01/29 22:32:07 ajc
2143 * Shuffled some code and comments around; minor cleanup
2145 Revision 400.87 2003/01/28 15:37:12 ajc
2146 * All functions which read binary data from the server now make use of the
2147 read_server_binary() function in tools.c
2148 * Binary reads from server now have safety code to prevent infinite loops
2149 * All output of MIME objects is now done with http_transmit_thing()
2151 Revision 400.86 2003/01/19 06:28:04 ajc
2152 * Minimum required Citadel version 6.05
2154 Revision 400.85 2003/01/16 04:41:26 ajc
2155 * When displaying edit controls for time of day in the calendar, only show
2156 minutes that are multiples of 5 ... unless the existing value is not a
2157 multiple of 5, in which case we show that too.
2159 Revision 400.84 2003/01/15 17:34:04 ajc
2160 * event.c: fixed a misspelling
2161 * config.guess, config.sub: updated using latest from ftp.gnu.org
2163 Revision 400.83 2003/01/14 04:21:27 ajc
2164 * Only offer views which make sense for the default view of a room
2166 Revision 400.82 2003/01/13 03:34:33 ajc
2167 * Get ready for the 4.10 release
2169 Revision 400.81 2003/01/12 23:22:53 ajc
2170 * configure.in: check for libical v0.24 or newer
2172 Revision 400.80 2003/01/07 04:56:17 ajc
2173 * Complete the free/busy transparency handling in the form
2174 * Default times for new events are now in the correct timezone
2176 Revision 400.79 2003/01/06 18:01:35 ajc
2177 * Begin handling of TRANSP property to show event times as free or
2178 busy (not finished).
2180 Revision 400.78 2003/01/05 21:02:14 ajc
2181 * Summary page: three columns are now all the same width
2183 Revision 400.77 2003/01/05 20:56:05 ajc
2184 * minor fix for previous checkin
2186 Revision 400.76 2003/01/05 20:51:01 ajc
2187 * Display PARTSTAT for attendees
2189 Revision 400.75 2003/01/05 05:01:00 ajc
2190 * Add "today's calendar events" to the summary page.
2192 Revision 400.74 2003/01/05 04:27:28 ajc
2193 * Add "Tasks" to the summary page
2195 Revision 400.73 2002/12/28 05:44:09 ajc
2196 * ical_dezonify.c: brought over new version from the Citadel source (again)
2198 Revision 400.72 2002/12/28 05:12:45 ajc
2199 * ical_dezonify.c: brought over new version from the Citadel source.
2201 Revision 400.71 2002/12/26 04:04:48 ajc
2202 * Perform CHEK command when automatically establishing sessions, not just
2203 when one is explicitly created. Some stuff is missing otherwise.
2205 Revision 400.70 2002/12/25 23:18:06 ajc
2206 * Be more strategic about when to call ical_dezonify()
2207 (This may be the last set of fixes. I hope so.)
2209 Revision 400.69 2002/12/25 21:39:38 ajc
2210 * ical_dezonify.c: added.
2211 * calendar.c: convert incoming ical messages to UTC
2212 (the usual routines will then convert them to local time for display)
2214 Revision 400.68 2002/12/25 07:06:00 ajc
2215 * Tweaked the code to work with libical 0.24
2217 Revision 400.67 2002/12/20 04:50:00 ajc
2218 * When saving a calendar event, increment the SEQUENCE property.
2220 Revision 400.66 2002/12/18 05:03:39 ajc
2221 * In the calendar code, changed all "struct tm *" to "struct tm" and changed
2222 all "tm = localtime(foo)" to "memcpy(&tm, localtime(foo), sizeof(struct tm))"
2223 Because the libc-allocated buffer was getting clobbered.
2224 * This fixes the problem fleeb reported with Feb 1 events making it go nuts.
2226 Revision 400.65 2002/12/17 05:01:39 ajc
2227 * Prettied up the calendar day view layout
2228 * Hour/minute editing fields now use am/pm hours and 2-digit minutes
2230 Revision 400.64 2002/12/16 04:43:30 ajc
2231 * Correctly handle local time zone when figuring out which day and time to
2232 display events on calendar month/day views. This also seems to have
2233 fixed the bug that was causing events to sometimes get lost when saved.
2235 Revision 400.63 2002/12/15 05:50:59 ajc
2236 * Form editing of date/time fields now assumes that the icaltimetype being
2237 manipulated is in UTC. It converts to/from local time for editing.
2239 Revision 400.62 2002/12/10 23:25:47 ajc
2240 * Display attendees in message view of calendar objects
2242 Revision 400.61 2002/12/07 22:12:59 ajc
2243 * Handle incoming RSVP's for meetings. (Note: this will not actually work
2244 until I implement the Citadel server function which it calls.)
2246 Revision 400.60 2002/11/30 21:34:51 ajc
2247 * Submit organizer in a hidden field, in case the server needs it
2249 Revision 400.59 2002/11/30 04:46:46 ajc
2250 * First cut at adding/removing attendees to an event
2251 (Actual invitations should be sent by the Citadel server)
2253 Revision 400.58 2002/11/29 23:56:19 ajc
2254 * Completed "me as organizer" -- the user's own e-mail address is inserted
2255 as the organizer of new events. Detect when the user is the organizer and
2256 enable/disable the attendees box accordingly.
2258 Revision 400.57 2002/11/29 16:38:37 ajc
2259 * Started some "me as organizer" stuff. (BROKEN BUILD ... I'll fix soon.)
2261 Revision 400.56 2002/11/28 06:03:24 ajc
2262 * Issue an ISME command when editing an event, to determine whether the user
2263 viewing the event is the organizer. (Will use this later to allow/disallow

2402 Revision 400.18 2002/09/20 03:54:44 ajc

2424 * When a text/calendar MIME type is discovered in a message, send it to
2425 the (currently skeleton) parser in calendar.c
2426 * calendar.c: skeleton parser for calendar objects which currently just
2427 creates an icalcomponent object and frees it.
2429 Revision 400.11 2002/09/15 03:16:24 ajc
2430 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with
2431 function namespace in libical
2433 Revision 400.10 2002/09/15 02:50:55 ajc
2434 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
2436 Revision 400.9 2002/09/14 21:33:31 ajc
2437 * Backed out compression of inlines -- not all browsers appear to handle it
2439 Revision 400.8 2002/09/14 20:20:29 ajc
2440 * Attempting to push more stuff through compression. I've introduced some
2441 sort of deadlock bug that I can't seem to find yet...

2444 * Compress output_image() graphics
2446 Revision 400.6 2002/09/14 16:26:35 ajc
2447 * output_image() now reads the entire image from Citadel into a buffer before

2450 Revision 400.5 2002/09/14 04:52:59 ajc
2451 * Look for the "libical" calendaring library and link it in if present...

2456 Revision 400.3 2002/09/13 20:40:53 ajc
2457 * Detect when the client browser is capable of gzip encoding
2458 (actual encoding is not implemented yet)
2460 Revision 400.2 2002/09/13 15:54:40 ajc

2474 Revision 323.67 2002/09/06 03:59:11 ajc
2475 * Added an "About this server" panel to the Summary page.

2481 Revision 323.65 2002/08/26 01:24:09 ajc

2484 Revision 323.64 2002/08/24 15:30:48 ajc

2490 Revision 323.62 2002/08/23 03:37:19 ajc

2503 Revision 323.58 2002/08/16 03:51:12 ajc

2715 * Reverted all of the navbar and iconbar functions back to plain, ordinary
2716 link tags. The nifty JavaScript stuff is now used only to light up the
2717 buttons during mouse hovers, and nothing more.

2777 and bail out without bothering the Citadel server.
2779 Revision 301.6 2001/08/22 16:38:06 ajc
2780 * Added the "-c" command line option to generate optional cookies indicating
2781 the host name of the server. This makes it easy to put a cluster of WebCit
2782 servers behind (for example) an Arrowpoint load balancer.

2823 queue length to 100 for use on big systems. Also, during startup, the
2824 initial startup thread now exits after creating the worker threads, instead
2825 of becoming a worker thread itself. For some reason Solaris had problems
2826 with the latter method.
2828 Revision 213.22 2001/06/07 03:16:57 ajc
2829 * Brought over an updated mime parser from Citadel

2959 Revision 211.19 2000/05/18 02:33:39 ajc

2977 crashing every session, every time. (?)
2978 * End the session after displaying robots.txt or nocookies.html, to prevent
2979 big session logjams when either of these conditions are met
2981 Revision 211.14 2000/04/15 15:43:46 nbryant
2982 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

3072 Revision 1.111 1999/12/03 17:59:53 ajc
3073 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
3074 pseudocode so the build is currently broken.

3079 Revision 1.109 1999/12/03 05:09:54 ajc

3106 Revision 1.101 1999/10/06 02:44:02 ajc
3107 * Per Nick's request, removed the key bindings stuff. He knows how to fit
3108 it back in when it's fixed. Also added more attempts at cache disabling,
3109 but it still doesn't work in the StarOffice browser. I don't know why.
3111 Revision 1.100 1999/10/02 03:26:14 ajc
3112 * Merged in Nick's bit of JavaScript to handle key commands.
3113 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is

3127 * webcit.c: exit Webcit sessions semi-gracefully when the connection
3128 to a Citadel server fails.
3129 * messages.c: don't auto-link URL's in messages if it would cause
3132 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3133 * Recompiled the Java chat applet using a genuine JDK 1.0.2
3134 compiler. This should make more browsers happy.
3136 Wed Jun 30 19:19:59 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

3155 Mon Jun 7 21:59:45 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3156 * Session no longer locks up when an express message is cancelled

3168 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3169 * Ditched the frames mode completely. It wasn't working properly in,
3170 among other places, IE 5. Die, Bill, Die.
3172 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3173 * Fixed the behavior of the "forget room" routine, to properly handle
3174 the transition back to the Lobby after it's all done.
3175 * Added ExpressMessageCat() to allow code to send the user messages
3176 along with incoming express messages
3177 * WebCit now sends the name of the end user's browser as the client
3178 name in a Citadel IDEN command rather than its own name.
3180 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3181 * Minor code cleanups

3185 * Top-aligned all the cells in the fake frames in non-frames mode
3187 Fri May 14 23:37:02 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3188 * Initial entry to _BASEROOM_ at login now done as a Skip instead
3189 of a Goto, in order to prevent it from first marking all msgs old.
3191 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3192 * Replaced _most_ gotoroom() calls with smart_goto(), a version
3193 which can differentiate the needs of frames and noframes modes
3195 Sat May 8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3196 * webserver.c: added "-t" option to send traces somewhere else
3198 Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

3200 requests a non-root page and there is no cookie set
3201 * webserver.c: took my name off the copyright notice (it's a group
3204 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3205 * Reworked a lot of the structure, made more HTML "embeddable"
3206 * Changed the noframes mode to display "fake" frames using tables
3208 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nick@ulster.net>
3209 Changed some output formatting (mainly <FONT> tags).
3210 Changed who.c to use urlescputs() rather than escputs()
3211 in urls so GOTOs and User Profiles work when the string has a
3214 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3215 http://www.webreference.com/dhtml/column18/menuFrLoad.html
3216 How to cause "onLoad=" to cause a sibling frame to refresh without
3217 having to use the nonportable HTTP "Window-Target:" directive. Began
3218 implementation of this; it should allow portable NS/IE compatibility.
3220 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3221 * Implemented "access level required to create rooms"
3223 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3224 * webcit.c: modified getz() to *exit* the program when fgets()
3225 returns an error. This is actually the desired behavior; it would
3226 otherwise busy-loop forever on a broken pipe.
3228 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3229 * webcit.c: added to getz() the ability to return an error code;
3230 implemented this in the main loop, hopefully fixing problems
3231 * Added "braindamage" file (frames/JS browser compatibility list)
3232 * Added HTTP "User-agent:" detection
3233 * wildmat.c, braindamage.c: added
3234 * Initial value of 'noframes' is now set by the braindamage check
3235 * Ran everything through "indent -kr -i8"
3236 * roomops.c: in room list, print a in otherwise empty cells
3238 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
3239 * context_loop.c: warning fix
3240 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
3242 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3243 * Resolve the name of the connecting host and pass it on to Citadel
3245 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3246 * wDumpContent() is now responsible for </BODY></HTML> most of the
3247 time (parameter settable) so that the main menu can easily be
3248 embedded in every page when running in noframes mode
3249 * noframes mode selection is now carried in the cookie
3251 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3252 * Made the frames stuff less dependent on the HTML TARGET= directive
3253 and more dependent on the HTTP Window-target: directive.
3254 * Made the system semi-navigable in noframes mode.
3256 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3257 * Brought over the new room listing code and <G>oto heuristics
3258 from the main Citadel tree, to pay attention to floor/room ordering
3260 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3261 * Modified the back end of mime_parser to use callbacks instead of
3262 doing something specific. Now we can use it elsewhere.
3264 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3265 * Fixed the bugs in "Site-wide configuration"
3266 * Added a "generic server commands" screen
3268 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3269 * Reduced the multiple cookies down to one cookie combining all data.
3271 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3272 * Removed wc_host and wc_port cookies.
3273 * Added an "edit your session" screen to change your wholisting.
3275 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3276 * Added "enter registration"
3277 * Set up automatic trigger of Enter Registration when the server
3279 * Established that a one-to-one WebCit/Citadel correspondence will
3280 be required. No big deal due to shared code segments.
3281 * Added "change password"
3282 * Added networking configuration screens. These still need testing.
3283 * Added a "kill session" link to each line of the wholist when
3284 logged in as an aide, and the screens to perform this operation.
3286 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3287 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
3288 * "Finished" the MIME parser.
3289 * Got image uploads working.

3295 Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3296 * Wrote mime_parser.c for handling of image uploads. This will also
3297 be used in future Citadel MIME projects.
3299 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3300 * Fixed a bug in the room banner display code

3305 * Added "edit room info file"
3308 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3309 * Changed the "auto read new" functionality from a meta refresh tag
3310 to an "onload" directive (the former was causing graphics problems)
3311 * Added "create room"
3314 Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3315 * Got the Zap and List-Zapped commands working

3320 * Added the screens to send pages
3321 * Changed message headers to display in bigger font, non-boldface
3322 * Added the chat system
3323 * Added goto private rooms
3325 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3326 * Replace "Citadel" in menu bar with the Citadel logo
3328 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
3329 * automatically regenerate Makefile when Makefile.in changes
3331 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3332 * context_loop.c: Moved "remove session" into its own function.
3333 Check for dead webcit child process before each transaction.
3334 * Ignore SIGPIPE; this seems to magically make the program bulletproof
3335 against broken HTTP connections.
3336 * Added a housekeeping thread to periodically remove dead sessions
3337 and kill idle sessions.
3338 * messages.c: added "delete message" functionality
3339 * messages.c: added "move message" functionality
3340 * userlist.c: added. This adds "userlist" and "show user" functions.

3351 * webserver.c: remove commented-out references to SO_LINGER
3353 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3354 * context_loop.c: After fork(), child process closes the HTTP socket
3355 so when the parent process closes it, it actually _does_ close.
3356 Otherwise, aIEeeee and possibly other browsers will hang.
3357 * Added support for graphics images retrieved from the Citadel server.
3358 * Set up login banner graphic and background image graphic
3360 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
3361 * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix
3363 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3364 * Smoothed out some of the login/logout code. Failed authentication
3365 now works the way it should.
3366 * Added support for new user login (still need to handle registration).
3368 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3369 * Discovered that the HTTP socket problem is related to a socket that
3370 isn't properly lingering on close. Temporarily hacked a sleep(10)
3371 into context_loop.c until it is figured out.
3373 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3374 * Did a little debugging, still trying to figure out why logging in
3375 displays "Connection reset by peer" error. It used to work...
3377 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
3378 * Makefile.in: updated dependencies
3380 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
3381 * Fixed broken interpretation of variables specified in the URL
3382 * added new "action" variable to make main loop simpler
3384 1998-12-06 Nathan Bryant <bryant@cs.usm.maine.edu>

3386 * context_loop.c: warning fix
3388 1998-12-05 Nathan Bryant <bryant@cs.usm.maine.edu>

3394 1998-12-04 Nathan Bryant <bryant@cs.usm.maine.edu>
3395 * webserver.c, context_loop.c, webcit.c: add commandline args for host
3397 * converted to autoconf and began port to Digital UNIX
3399 * context_loop.c: moved the monster 64k buffer array off the stack
3400 * tcp_sockets.c: getservbyname() doesn't set errno.
3402 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
3403 * webserver.c: warning fix
