2 Revision 500.22 2003/08/22 00:47:27 ajc
3 * setup is now working, but it still needs a way to detect a running WebCit
5 Revision 500.21 2003/08/22 00:25:40 ajc
6 * Added a skeleton "setup" program to the tree. It does not work yet.
8 Revision 500.20 2003/08/20 03:48:55 ajc
9 * Added iconbar shortcut to Contacts room
10 * Minimum required Citadel is now 6.11
12 Revision 500.19 2003/08/20 03:07:25 ajc
13 * Address book "single card" view now suppresses "reading nn message" and
14 instead shows the letter indices across the top
15 * Clicking on an address in a vCard now connects to WebCit mail instead
16 of a browser mailto: link
18 Revision 500.18 2003/08/19 04:18:43 ajc
19 * Changed things around in the address book view. Made it sorted and
20 more clickable and better looking...
22 Revision 500.17 2003/08/12 18:54:03 error
23 * messages.c: fix off-by-one-error in selector bar
25 Revision 500.16 2003/08/07 22:18:03 ajc
26 * Add the Summary Page to the customizable iconbar
28 Revision 500.15 2003/08/07 03:51:51 ajc
29 * Customizable icon bar as: pictures and text, pictures, text
31 Revision 500.14 2003/08/05 03:52:14 ajc
32 * First working version of the customizable iconbar. It contains a basic
33 set of options and now automatically refreshes when it's customized.
35 Revision 500.13 2003/08/04 03:50:29 ajc
36 * First cut at the customizable iconbar is done. A bunch of generic options
37 are there. Still need to get the actual iconbar to refresh when changes
40 Revision 500.12 2003/08/03 21:02:01 ajc
41 * More work on customizable iconbar
43 Revision 500.11 2003/08/02 05:25:46 ajc
44 * Laid the groundwork for a customizable iconbar
46 Revision 500.10 2003/07/30 03:57:49 ajc
47 * Add config.c_purge_hour to config screen
49 Revision 500.9 2003/07/06 22:06:59 ajc
50 * When converting "anything that looks like a URL" to a real link, first
51 make sure that it isn't already inside a link. This fixes most of the
52 long, ugly URL strings sent by eBay.
53 * Automatically dismantle mailto: links in HTML messages, and convert
54 them to WebCit mail links (clicking on it sends the user to the Mail
55 room and begins composing a new message with the recipient and subject
56 fields pre-populated).
58 Revision 500.8 2003/06/29 20:51:21 ajc
59 * Worked around a rendering bug in Satan's Browser that was causing it
60 to draw the calendar month view much wider than the actual screen wdith
62 Revision 500.7 2003/06/28 04:09:37 error
63 * roomops.c: Backout change to display one less box in the first column in
64 roomlist view, it doesn't seem to work for everyone
66 Revision 500.6 2003/06/28 03:52:51 error
67 * Don't tell browsers not to cache static documents
69 Revision 500.5 2003/06/28 03:35:23 error
70 * roomops.c: Display one less floor in the first column in romlist view
72 Revision 500.4 2003/06/26 03:37:58 ajc
73 * Allow anonymous HTTP requests for /freebusy/user%20name.vcf (or .vfb)
74 This will allow some groupware clients to browse the free/busy times of
75 other users on the system.
77 Revision 500.3 2003/06/21 05:17:21 ajc
78 * Better alignment of system messages
79 * Exterminated display_error() and replaced it with WC->ImportantMessage
80 which is displayed in a bubble on top of whatever page you're on next.
81 * Small cosmetic changes
82 * Fixed some nesting problems in output_headers()
84 Revision 500.2 2003/06/20 03:39:27 ajc
85 * Optimization to floor layout in box view
87 Revision 500.1 2003/06/20 03:04:26 ajc
88 * "Reply" button on messages now handles IGnet recipients correctly
90 Revision 500.0 2003/06/10 04:23:08 ajc
93 Revision 410.50 2003/06/10 04:22:58 ajc
94 * Updated docs and headers for 5.00 release
96 Revision 410.49 2003/06/10 04:05:23 ajc
97 * De-tabled the left side icon bar and reduced one of the graphics, so
98 that all of the rounded corners show up in Satan's Browser.
100 Revision 410.48 2003/06/10 03:47:41 ajc
101 * style.css: added font selection to default <BODY> tag
103 Revision 410.47 2003/06/06 03:26:03 ajc
104 * Satan's Browser insists on putting bloody acres of whitespace to the
105 right of any bulleted list items, making any multi-column table containing
106 a list take more than the entire screen. Removed all such lists so it
107 looks ok. If you are reading this and you are a Microsoft employee, please
108 commit suicide before you break anything else.
110 Revision 410.46 2003/06/06 02:22:07 ajc
111 * Changed the upper left and upper right bounded box corners to a solid
112 blue (#204B78) instead of gradiated, because it was looking funny in
113 256-color mode. It also looked funny in Internet Explorer, but people
114 who use Internet Explorer are contributing to terrorism and really don't
115 deserve Web access in the first place. So I really just fixed this to make
116 it look good in 256-color Netscape.
118 Revision 410.45 2003/06/05 21:37:37 ajc
119 * Cosmetic changes. Attempting to fix b0rken rendering of main menu
120 in b0rken IE browser. Die, Bill, Die.
122 Revision 410.44 2003/06/05 03:52:29 ajc
123 * Buncha cosmetic changes
125 Revision 410.43 2003/06/04 03:41:25 ajc
126 * Change the appearance of rooms with and without new messages in the
127 room list -- now defined using CSS
129 Revision 410.42 2003/06/03 03:57:42 ajc
130 * Tightened up the room banner a bit. Smaller padding, smaller font,
133 Revision 410.41 2003/05/31 21:36:45 ajc
136 Revision 410.40 2003/05/26 21:05:42 ajc
137 * availability.c: brought over ical_ctdl_is_overlap() from Citadel. Used
138 it to complete the free/busy checking for attendee availability.
140 Revision 410.39 2003/05/26 05:44:45 ajc
141 * event.c: fix compiler warning
143 Revision 410.38 2003/05/26 05:39:46 ajc
144 * webcit.h: change minimum required Citadel server to 6.07 due to FREEBUSY
145 bug fixed in Citadel.
147 Revision 410.37 2003/05/26 05:28:13 ajc
148 * serv_func.c: added utility function read_server_text()
149 * availability.c: banged out more of this code -- still not complete
151 Revision 410.36 2003/05/26 03:28:02 ajc
152 * Getting closer to doing the availability check. Created new source
153 module 'availability.c' for this purpose. Stub function is in place.
155 Revision 410.35 2003/05/25 04:25:12 ajc
156 * siteconfig.c: fixed a spelling error
157 * event.c: add a "Check attendee availability" button, and the code to
158 bypass saving the event to the server, do something with it, and then
159 feed the twiddled data structure back to the form display function for
160 further editing. What's still missing is the code to do the actual
163 Revision 410.34 2003/05/24 22:22:35 ajc
164 * Small stylesheet hack to make it work with b0rken IE
166 Revision 410.33 2003/05/24 22:13:08 ajc
167 * Changed the login banner a bit
169 Revision 410.32 2003/05/20 03:25:41 ajc
170 * Separate event invitees with newlines instead of commas.
172 Revision 410.31 2003/05/19 19:55:09 ajc
173 * summary.c: eliminate compiler warnings about unused variables when
174 compiling a WebCit service without calendar support
176 Revision 410.30 2003/05/18 02:05:33 ajc
177 * More conversion of screens to the new look-and-feel.
179 Revision 410.29 2003/05/16 04:11:29 ajc
180 * We don't need no steenking workaround. Problem fixed. MIME parser not
181 broken. Web server was calling it with bad parameters. All fixed now.
182 * Slightly tweaked the look of the tabs in the room edit screen. Still looks
185 Revision 410.28 2003/05/15 04:52:26 ajc
186 * Minor workaround in web forms to handle mime parser problem in uploads
188 Revision 410.27 2003/05/15 03:35:59 ajc
189 * look and feel overhaul -- almost done!
191 Revision 410.26 2003/05/14 03:46:35 ajc
192 * More background cleanup
194 Revision 410.25 2003/05/05 17:19:46 ajc
195 * Cleanups to summary page when running on a non ical enabled system
196 * Use non breaking spaces in summary page box titles
198 Revision 410.24 2003/05/04 04:22:41 ajc
199 * Display body of messages on a white background. I am doing this in order
200 to prepare for making the general background of the screen a darker color.
202 Revision 410.23 2003/05/04 02:54:55 ajc
203 * Summary page now uses our cutesy new rounded window boxes
205 Revision 410.22 2003/05/03 21:28:41 ajc
206 * Added in a slick new box style and put the room lists in it
208 Revision 410.21 2003/05/03 16:57:04 ajc
209 * In the 'folders' and 'portal' views, change the folder delimiter
210 from / to \ to avoid conflict with room names that have slashes
212 Revision 410.20 2003/05/03 16:23:29 ajc
213 * Enforce three columns in portal view of room list
215 Revision 410.19 2003/05/03 04:52:32 ajc
216 * Added an experimental new "portal view" to the room list options
218 Revision 410.18 2003/05/02 03:23:41 ajc
219 * Minor change to room list algorithm
221 Revision 410.17 2003/05/01 15:33:05 ajc
222 * Fixed a potential memory leak in enumeration of MIME parts
224 Revision 410.16 2003/05/01 03:11:35 ajc
225 * When static content is requested, fetch it without trying to connect
228 Revision 410.15 2003/04/30 05:00:00 ajc
229 * Added the ability to compose messages with file attachments uploaded from
232 Revision 410.14 2003/04/27 04:46:02 ajc
233 * Replace LKRN/LKRO in "folders view" room list with a single LKRA that
234 observes the flag designating the presence of new messages. (The "rooms
235 view" uses an LKRN/LKRO pair *per floor* and has the same inefficiency,
236 but that view may get axed soon.)
238 Revision 410.13 2003/04/26 21:57:53 ajc
239 * tcp_sockets.c: when an outgoing socket connection fails, close the socket
240 before returning an error code to avoid a file descriptor leak
242 Revision 410.12 2003/04/19 21:42:36 ajc
243 * Repaired all my b0rken COLOR tags
244 * Replaced most FONT tags with SPAN tags
247 Revision 410.11 2003/04/19 19:58:10 ajc
248 * Lots of great changes from Nick to make the site CSS-enabled.
250 Revision 410.10 2003/04/14 04:04:40 ajc
251 * First cut of CSS-izing WebCit. Probably b0rken.
253 Revision 410.9 2003/04/09 04:02:32 ajc
254 * Remove the defaulthost/defaultport vs. c_host/c_port stuff -- we haven't
255 supported the idea of one WebCit connecting to multiple Citadels for a
256 long time. Now it's just one set of variables, called ctdlhost/ctdlport.
257 * When connecting to Citadel through a Unix domain socket, don't try to make
258 the Java chat applet available.
260 Revision 410.8 2003/03/31 03:32:19 ajc
261 * messages.c: check for 000 terminator while parsing RFC822 headers to
262 prevent getting hung up while displaying certain badly formatted messages.
264 Revision 410.7 2003/03/30 06:13:19 ajc
265 * When reading from the server, do not treat CR as end-of-line because
266 there's probably an LF coming after it. Instead, keep reading to the LF
268 * No not underline links in the icon bars
270 Revision 410.6 2003/03/17 04:17:41 ajc
271 * Call to accept() was being made with an uninitialized variable for the
272 third argument. Changed the second and third argument to NULL and 0 because
273 we don't really need accept() to fill up a buffer full of information that
274 we'll never use. (Thanks to SteveV for reporting the bug and helping to
276 * Removed the mutex wrapper around select() because we don't need it. All
277 idle worker threads now block on select() and one of them will wake up when
278 a connection arrives.
280 Revision 410.5 2003/03/15 20:55:03 ajc
281 * When a requested image is not available on the Citadel server, send a
282 1x1 transparent GIF instead of 404 error.
284 Revision 410.4 2003/03/14 04:21:57 ajc
285 * clone events to be encapsulated before saving, because the original
286 instance may already have a parent, and that makes crashy crashy
288 Revision 410.3 2003/03/13 05:57:17 ajc
289 * More encapsulation. Warning: there are bugs in this!!
291 Revision 410.2 2003/03/13 05:20:23 ajc
292 * Various changes to the calendar service to handle messages containing
293 fully encapsulated VCALENDAR components instead of only unencapsulated
294 VEVENT subcomponents. We have to move in this direction for compatibility
297 Revision 410.1 2003/03/01 22:07:19 ajc
298 * New user registration, as well as existing user re-registration, now
299 uses the vCard editing screen.
300 * Administratively editing users' address book entries now works again,
301 mainly due to a fix in the Citadel server. Now requiring Citadel 6.06
302 in order to enforce this.
304 Revision 410.0 2003/02/19 03:49:33 ajc
307 Revision 400.90 2003/02/19 03:49:17 ajc
308 * latest config.guess and config.sub from www.gnu.org
310 Revision 400.89 2003/02/07 04:44:17 ajc
311 * Replaced sleep() with a function that sleeps using select() in order to
312 avoid potential issues with SIGALRM. Possible fix for weird behavior
313 when running on a Macintosh.
315 Revision 400.88 2003/01/29 22:32:07 ajc
316 * Shuffled some code and comments around; minor cleanup
318 Revision 400.87 2003/01/28 15:37:12 ajc
319 * All functions which read binary data from the server now make use of the
320 read_server_binary() function in tools.c
321 * Binary reads from server now have safety code to prevent infinite loops
322 * All output of MIME objects is now done with http_transmit_thing()
324 Revision 400.86 2003/01/19 06:28:04 ajc
325 * Minimum required Citadel version 6.05
327 Revision 400.85 2003/01/16 04:41:26 ajc
328 * When displaying edit controls for time of day in the calendar, only show
329 minutes that are multiples of 5 ... unless the existing value is not a
330 multiple of 5, in which case we show that too.
332 Revision 400.84 2003/01/15 17:34:04 ajc
333 * event.c: fixed a misspelling
334 * config.guess, config.sub: updated using latest from ftp.gnu.org
336 Revision 400.83 2003/01/14 04:21:27 ajc
337 * Only offer views which make sense for the default view of a room
339 Revision 400.82 2003/01/13 03:34:33 ajc
340 * Get ready for the 4.10 release
342 Revision 400.81 2003/01/12 23:22:53 ajc
343 * configure.in: check for libical v0.24 or newer
345 Revision 400.80 2003/01/07 04:56:17 ajc
346 * Complete the free/busy transparency handling in the form
347 * Default times for new events are now in the correct timezone
349 Revision 400.79 2003/01/06 18:01:35 ajc
350 * Begin handling of TRANSP property to show event times as free or
353 Revision 400.78 2003/01/05 21:02:14 ajc
354 * Summary page: three columns are now all the same width
356 Revision 400.77 2003/01/05 20:56:05 ajc
357 * minor fix for previous checkin
359 Revision 400.76 2003/01/05 20:51:01 ajc
360 * Display PARTSTAT for attendees
362 Revision 400.75 2003/01/05 05:01:00 ajc
363 * Add "today's calendar events" to the summary page.
365 Revision 400.74 2003/01/05 04:27:28 ajc
366 * Add "Tasks" to the summary page
368 Revision 400.73 2002/12/28 05:44:09 ajc
369 * ical_dezonify.c: brought over new version from the Citadel source (again)
371 Revision 400.72 2002/12/28 05:12:45 ajc
372 * ical_dezonify.c: brought over new version from the Citadel source.
374 Revision 400.71 2002/12/26 04:04:48 ajc
375 * Perform CHEK command when automatically establishing sessions, not just
376 when one is explicitly created. Some stuff is missing otherwise.
378 Revision 400.70 2002/12/25 23:18:06 ajc
379 * Be more strategic about when to call ical_dezonify()
380 (This may be the last set of fixes. I hope so.)
382 Revision 400.69 2002/12/25 21:39:38 ajc
383 * ical_dezonify.c: added.
384 * calendar.c: convert incoming ical messages to UTC
385 (the usual routines will then convert them to local time for display)
387 Revision 400.68 2002/12/25 07:06:00 ajc
388 * Tweaked the code to work with libical 0.24
390 Revision 400.67 2002/12/20 04:50:00 ajc
391 * When saving a calendar event, increment the SEQUENCE property.
393 Revision 400.66 2002/12/18 05:03:39 ajc
394 * In the calendar code, changed all "struct tm *" to "struct tm" and changed
395 all "tm = localtime(foo)" to "memcpy(&tm, localtime(foo), sizeof(struct tm))"
396 Because the libc-allocated buffer was getting clobbered.
397 * This fixes the problem fleeb reported with Feb 1 events making it go nuts.
399 Revision 400.65 2002/12/17 05:01:39 ajc
400 * Prettied up the calendar day view layout
401 * Hour/minute editing fields now use am/pm hours and 2-digit minutes
403 Revision 400.64 2002/12/16 04:43:30 ajc
404 * Correctly handle local time zone when figuring out which day and time to
405 display events on calendar month/day views. This also seems to have
406 fixed the bug that was causing events to sometimes get lost when saved.
408 Revision 400.63 2002/12/15 05:50:59 ajc
409 * Form editing of date/time fields now assumes that the icaltimetype being
410 manipulated is in UTC. It converts to/from local time for editing.
412 Revision 400.62 2002/12/10 23:25:47 ajc
413 * Display attendees in message view of calendar objects
415 Revision 400.61 2002/12/07 22:12:59 ajc
416 * Handle incoming RSVP's for meetings. (Note: this will not actually work
417 until I implement the Citadel server function which it calls.)
419 Revision 400.60 2002/11/30 21:34:51 ajc
420 * Submit organizer in a hidden field, in case the server needs it
422 Revision 400.59 2002/11/30 04:46:46 ajc
423 * First cut at adding/removing attendees to an event
424 (Actual invitations should be sent by the Citadel server)
426 Revision 400.58 2002/11/29 23:56:19 ajc
427 * Completed "me as organizer" -- the user's own e-mail address is inserted
428 as the organizer of new events. Detect when the user is the organizer and
429 enable/disable the attendees box accordingly.
431 Revision 400.57 2002/11/29 16:38:37 ajc
432 * Started some "me as organizer" stuff. (BROKEN BUILD ... I'll fix soon.)
434 Revision 400.56 2002/11/28 06:03:24 ajc
435 * Issue an ISME command when editing an event, to determine whether the user
436 viewing the event is the organizer. (Will use this later to allow/disallow
437 sending out invitations.)
439 Revision 400.55 2002/11/26 05:01:04 ajc
440 * Began handling attendee fields
442 Revision 400.54 2002/11/16 23:40:11 ajc
445 Revision 400.53 2002/11/16 23:15:02 ajc
446 * Make the "all day event" shadebox smaller (month view) - no border.
447 * Fixed bug that caused any events following an all day event to also appear
450 Revision 400.52 2002/11/16 05:40:54 ajc
451 * When adding new events to the calendar, default to the month [and day]
452 currently being viewed.
453 * Hotlink each hour of the day view to an add-new-event for that day/hour.
455 Revision 400.51 2002/11/15 05:05:47 ajc
456 * Put in back/forward (yesterday/tomorrow) links in calendar day view
458 Revision 400.50 2002/11/15 04:11:46 ajc
459 * Added even more nifty JavaScript to cause the hour/minute and end date
460 fields of a calendar event form to render as disabled when the "all day
461 event" box is checked -- not just when the user checks the box, but also
462 when the box begins its life already checked.

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

600 creates an icalcomponent object and frees it.
602 Revision 400.11 2002/09/15 03:16:24 ajc
603 * Changed decode_base64() to CtdlDecodeBase64() to avoid conflict with

606 Revision 400.10 2002/09/15 02:50:55 ajc
607 * Duh. I don't need to twiddle CFLAGS when autoconf provides -DHAVE_ZLIB_H
609 Revision 400.9 2002/09/14 21:33:31 ajc

612 Revision 400.8 2002/09/14 20:20:29 ajc
613 * Attempting to push more stuff through compression. I've introduced some
614 sort of deadlock bug that I can't seem to find yet...
616 Revision 400.7 2002/09/14 20:00:22 ajc
617 * Compress output_image() graphics
619 Revision 400.6 2002/09/14 16:26:35 ajc
620 * output_image() now reads the entire image from Citadel into a buffer before

631 (actual encoding is not implemented yet)
633 Revision 400.2 2002/09/13 15:54:40 ajc
634 * Reversed the above change because I broke it somehow

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

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

714 Revision 323.46 2002/07/13 04:39:59 ajc
715 * Handle multipart/alternative in a nicer way, giving us the opportunity to
716 output HTML instead of converting to text/plain and back. (Not finished.)
718 Revision 323.45 2002/07/11 03:17:03 ajc
719 * hacks to text_to_server() to transmit messages as HTML

953 * Added the "-c" command line option to generate optional cookies indicating
954 the host name of the server. This makes it easy to put a cluster of WebCit

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

1132 Revision 211.19 2000/05/18 02:33:39 ajc

1150 crashing every session, every time. (?)
1151 * End the session after displaying robots.txt or nocookies.html, to prevent
1152 big session logjams when either of these conditions are met
1154 Revision 211.14 2000/04/15 15:43:46 nbryant
1155 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

1245 Revision 1.111 1999/12/03 17:59:53 ajc
1246 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
1247 pseudocode so the build is currently broken.

1250 * Repaired HTTP output for image transfers and static content
1252 Revision 1.109 1999/12/03 05:09:54 ajc

1280 * Per Nick's request, removed the key bindings stuff. He knows how to fit
1281 it back in when it's fixed. Also added more attempts at cache disabling,
1282 but it still doesn't work in the StarOffice browser. I don't know why.
1284 Revision 1.100 1999/10/02 03:26:14 ajc
1285 * Merged in Nick's bit of JavaScript to handle key commands.
1286 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is

1301 to a Citadel server fails.
1302 * messages.c: don't auto-link URL's in messages if it would cause
1305 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1306 * Recompiled the Java chat applet using a genuine JDK 1.0.2

1324 Fri Jun 18 11:55:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1325 * Unknown URL's now display the main menu instead of diagnostics

1347 the transition back to the Lobby after it's all done.

1349 along with incoming express messages
1350 * WebCit now sends the name of the end user's browser as the client
1351 name in a Citadel IDEN command rather than its own name.
1353 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1354 * Minor code cleanups

1357 Mon May 17 20:59:36 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1358 * Top-aligned all the cells in the fake frames in non-frames mode
1360 Fri May 14 23:37:02 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1361 * Initial entry to _BASEROOM_ at login now done as a Skip instead
1362 of a Goto, in order to prevent it from first marking all msgs old.
1364 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1365 * Replaced _most_ gotoroom() calls with smart_goto(), a version
1366 which can differentiate the needs of frames and noframes modes
1368 Sat May 8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1369 * webserver.c: added "-t" option to send traces somewhere else
1371 Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1372 * context_loop.c: display an error page if the client browser
1373 requests a non-root page and there is no cookie set
1374 * webserver.c: took my name off the copyright notice (it's a group
1377 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1378 * Reworked a lot of the structure, made more HTML "embeddable"
1379 * Changed the noframes mode to display "fake" frames using tables
1381 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nick@ulster.net>
1382 Changed some output formatting (mainly <FONT> tags).
1383 Changed who.c to use urlescputs() rather than escputs()
1384 in urls so GOTOs and User Profiles work when the string has a
1387 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1388 http://www.webreference.com/dhtml/column18/menuFrLoad.html
1389 How to cause "onLoad=" to cause a sibling frame to refresh without
1390 having to use the nonportable HTTP "Window-Target:" directive. Began
1391 implementation of this; it should allow portable NS/IE compatibility.
1393 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1394 * Implemented "access level required to create rooms"
1396 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1397 * webcit.c: modified getz() to *exit* the program when fgets()
1398 returns an error. This is actually the desired behavior; it would
1399 otherwise busy-loop forever on a broken pipe.
1401 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1402 * webcit.c: added to getz() the ability to return an error code;
1403 implemented this in the main loop, hopefully fixing problems
1404 * Added "braindamage" file (frames/JS browser compatibility list)
1405 * Added HTTP "User-agent:" detection
1406 * wildmat.c, braindamage.c: added
1407 * Initial value of 'noframes' is now set by the braindamage check
1408 * Ran everything through "indent -kr -i8"
1409 * roomops.c: in room list, print a in otherwise empty cells
1411 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
1412 * context_loop.c: warning fix
1413 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
1415 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1416 * Resolve the name of the connecting host and pass it on to Citadel
1418 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1419 * wDumpContent() is now responsible for </BODY></HTML> most of the
1420 time (parameter settable) so that the main menu can easily be
1421 embedded in every page when running in noframes mode
1422 * noframes mode selection is now carried in the cookie
1424 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1425 * Made the frames stuff less dependent on the HTML TARGET= directive
1426 and more dependent on the HTTP Window-target: directive.
1427 * Made the system semi-navigable in noframes mode.
1429 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1430 * Brought over the new room listing code and <G>oto heuristics
1431 from the main Citadel tree, to pay attention to floor/room ordering
1433 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1434 * Modified the back end of mime_parser to use callbacks instead of
1435 doing something specific. Now we can use it elsewhere.
1437 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1438 * Fixed the bugs in "Site-wide configuration"
1439 * Added a "generic server commands" screen
1441 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1442 * Reduced the multiple cookies down to one cookie combining all data.
1444 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1445 * Removed wc_host and wc_port cookies.
1446 * Added an "edit your session" screen to change your wholisting.
1448 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1449 * Added "enter registration"
1450 * Set up automatic trigger of Enter Registration when the server
1452 * Established that a one-to-one WebCit/Citadel correspondence will
1453 be required. No big deal due to shared code segments.
1454 * Added "change password"
1455 * Added networking configuration screens. These still need testing.
1456 * Added a "kill session" link to each line of the wholist when
1457 logged in as an aide, and the screens to perform this operation.
1459 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1460 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
1461 * "Finished" the MIME parser.
1462 * Got image uploads working.
1463 * Added "add/edit user photo" screens.
1464 * Added "add/edit room graphic" screens.
1465 * Added "add/edit floor graphic" screens.
1466 * Fixed display of floor graphic in known rooms list.
1468 Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1469 * Wrote mime_parser.c for handling of image uploads. This will also
1470 be used in future Citadel MIME projects.
1472 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1473 * Fixed a bug in the room banner display code
1474 * Added "delete room"
1475 * Added "validate users"
1477 Mon Dec 28 00:26:01 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1478 * Added "edit room info file"
1481 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1482 * Changed the "auto read new" functionality from a meta refresh tag
1483 to an "onload" directive (the former was causing graphics problems)
1484 * Added "create room"
1487 Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1488 * Got the Zap and List-Zapped commands working
1489 * Added a convenience function to display a page with an error string
1490 * Automatically do a read-new-msgs whenever a new room banner is loaded
1492 Thu Dec 17 20:38:00 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1493 * Added the screens to send pages
1494 * Changed message headers to display in bigger font, non-boldface
1495 * Added the chat system
1496 * Added goto private rooms
1498 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1499 * Replace "Citadel/UX" in menu bar with the Citadel/UX logo
1501 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
1502 * automatically regenerate Makefile when Makefile.in changes
1504 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1505 * context_loop.c: Moved "remove session" into its own function.
1506 Check for dead webcit child process before each transaction.
1507 * Ignore SIGPIPE; this seems to magically make the program bulletproof
1508 against broken HTTP connections.
1509 * Added a housekeeping thread to periodically remove dead sessions
1510 and kill idle sessions.
1511 * messages.c: added "delete message" functionality
1512 * messages.c: added "move message" functionality
1513 * userlist.c: added. This adds "userlist" and "show user" functions.
1514 * roomops.c: fixed buggy implementation of ungoto
1515 * Set up an option in output_headers() to optionally print the most
1516 often used opening HTML as well as the HTTP headers.

1519 Fri Dec 11 21:14:36 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1520 * Brought over message reading and entry functions from old WebCit
1522 1998-12-10 Nathan Bryant <bryant@cs.usm.maine.edu>
1523 * context_loop.c: really fix the SO_LINGER stuff
1524 * webserver.c: remove commented-out references to SO_LINGER
1526 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1527 * context_loop.c: After fork(), child process closes the HTTP socket
1528 so when the parent process closes it, it actually _does_ close.
1529 Otherwise, aIEeeee and possibly other browsers will hang.
1530 * Added support for graphics images retrieved from the Citadel server.
1531 * Set up login banner graphic and background image graphic
1533 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
1534 * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix
1536 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1537 * Smoothed out some of the login/logout code. Failed authentication
1538 now works the way it should.
1539 * Added support for new user login (still need to handle registration).
1541 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1542 * Discovered that the HTTP socket problem is related to a socket that
1543 isn't properly lingering on close. Temporarily hacked a sleep(10)
1544 into context_loop.c until it is figured out.
1546 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1547 * Did a little debugging, still trying to figure out why logging in
1548 displays "Connection reset by peer" error. It used to work...
1550 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
1551 * Makefile.in: updated dependencies
1553 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
1554 * Fixed broken interpretation of variables specified in the URL
1555 * added new "action" variable to make main loop simpler
1557 1998-12-06 Nathan Bryant <bryant@cs.usm.maine.edu>
1558 * webserver.c: prototype vsnprintf
1559 * context_loop.c: warning fix
1561 1998-12-05 Nathan Bryant <bryant@cs.usm.maine.edu>
1562 * tcp_sockets.c: removed some dead code
1563 * context_loop.c: oops, I made a memory leak. fix fix fix. also close
1564 unused ends of pipes, fix a file descriptor leak and a race condition
1565 * portability enhancements
1567 1998-12-04 Nathan Bryant <bryant@cs.usm.maine.edu>
1568 * webserver.c, context_loop.c, webcit.c: add commandline args for host
1570 * converted to autoconf and began port to Digital UNIX
1572 * context_loop.c: moved the monster 64k buffer array off the stack
1573 * tcp_sockets.c: getservbyname() doesn't set errno.
1575 1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
1576 * webserver.c: warning fix
