13 * Tagged for the 2.12 release
15 Revision 211.19 2000/05/18 02:33:39 ajc
16 * Don't call whobbs() directly after changing masq room/host, it screws up the
17 refresh. It now calls an HTTP redirect page instead.

31 Revision 211.15 2000/04/20 02:42:23 ajc
32 * tcp_sockets.c: changed memcpy() to memset() in tcp_connectsock; this was

34 * End the session after displaying robots.txt or nocookies.html, to prevent
35 big session logjams when either of these conditions are met
37 Revision 211.14 2000/04/15 15:43:46 nbryant
38 * warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

96 * Removed overly verbose logging
98 Revision 1.120 1999/12/12 18:12:28 ajc

126 * Finished the overhaul. Now to tune...
128 Revision 1.111 1999/12/03 17:59:53 ajc
129 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
130 pseudocode so the build is currently broken.
132 Revision 1.110 1999/12/03 16:37:46 ajc
133 * Repaired HTTP output for image transfers and static content
135 Revision 1.109 1999/12/03 05:09:54 ajc
136 * Rewrote the HTTP engine and application coupling to run in a worker thread
137 model and to run as a single multithreaded program (eliminated helper
138 processes and pipes). It currently runs but has many large bugs.
140 Revision 1.108 1999/12/03 00:18:20 ajc
141 * Added ".c.o" rule to Makefile
143 Revision 1.107 1999/11/26 03:32:59 ajc

162 Revision 1.101 1999/10/06 02:44:02 ajc
163 * Per Nick's request, removed the key bindings stuff. He knows how to fit
164 it back in when it's fixed. Also added more attempts at cache disabling,
165 but it still doesn't work in the StarOffice browser. I don't know why.
167 Revision 1.100 1999/10/02 03:26:14 ajc
168 * Merged in Nick's bit of JavaScript to handle key commands.
169 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
170 in a text field. Right now you can't even log in.
172 Revision 1.99 1999/09/01 01:06:11 ajc
173 * Added "max message length" field in global config screen
175 Revision 1.98 1999/08/14 18:16:10 ajc

182 Mon Jul 12 23:30:24 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
183 * webcit.c: exit Webcit sessions semi-gracefully when the connection
184 to a Citadel server fails.
185 * messages.c: don't auto-link URL's in messages if it would cause
188 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
189 * Recompiled the Java chat applet using a genuine JDK 1.0.2

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

198 server command" to avoid nested server operations
200 Wed Jun 23 21:43:30 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
201 * webcit.c: added "back, top, next" buttons to bottom of each page

204 Tue Jun 22 14:53:05 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
205 * context_loop.c: rearranged some code to try to eliminate deadlocks
207 Fri Jun 18 11:55:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
208 * Unknown URL's now display the main menu instead of diagnostics

224 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
225 * Ditched the frames mode completely. It wasn't working properly in,
226 among other places, IE 5. Die, Bill, Die.
228 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
229 * Fixed the behavior of the "forget room" routine, to properly handle
230 the transition back to the Lobby after it's all done.
231 * Added ExpressMessageCat() to allow code to send the user messages
232 along with incoming express messages
233 * WebCit now sends the name of the end user's browser as the client
234 name in a Citadel IDEN command rather than its own name.
236 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
237 * Minor code cleanups
238 * New mail notification

243 Fri May 14 23:37:02 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
244 * Initial entry to _BASEROOM_ at login now done as a Skip instead
245 of a Goto, in order to prevent it from first marking all msgs old.
247 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
248 * Replaced _most_ gotoroom() calls with smart_goto(), a version
249 which can differentiate the needs of frames and noframes modes
251 Sat May 8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
252 * webserver.c: added "-t" option to send traces somewhere else
254 Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
255 * context_loop.c: display an error page if the client browser
256 requests a non-root page and there is no cookie set
257 * webserver.c: took my name off the copyright notice (it's a group
260 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
261 * Reworked a lot of the structure, made more HTML "embeddable"
262 * Changed the noframes mode to display "fake" frames using tables
264 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nicl@ulster.net>
265 Changed some output formatting (mainly <FONT> tags).
266 Changed who.c to use urlescputs() rather than escputs()
267 in urls so GOTOs and User Profiles work when the string has a
270 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
271 http://www.webreference.com/dhtml/column18/menuFrLoad.html
272 How to cause "onLoad=" to cause a sibling frame to refresh without
273 having to use the nonportable HTTP "Window-Target:" directive. Began
274 implementation of this; it should allow portable NS/IE compatibility.
276 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
277 * Implemented "access level required to create rooms"
279 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
280 * webcit.c: modified getz() to *exit* the program when fgets()
281 returns an error. This is actually the desired behavior; it would
282 otherwise busy-loop forever on a broken pipe.
284 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
285 * webcit.c: added to getz() the ability to return an error code;
286 implemented this in the main loop, hopefully fixing problems
287 * Added "braindamage" file (frames/JS browser compatibility list)
288 * Added HTTP "User-agent:" detection
289 * wildmat.c, braindamage.c: added
290 * Initial value of 'noframes' is now set by the braindamage check
291 * Ran everything through "indent -kr -i8"
292 * roomops.c: in room list, print a in otherwise empty cells
294 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
295 * context_loop.c: warning fix
296 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
298 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
299 * Resolve the name of the connecting host and pass it on to Citadel
301 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
302 * wDumpContent() is now responsible for </BODY></HTML> most of the
303 time (parameter settable) so that the main menu can easily be
304 embedded in every page when running in noframes mode
305 * noframes mode selection is now carried in the cookie
307 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
308 * Made the frames stuff less dependent on the HTML TARGET= directive
309 and more dependent on the HTTP Window-target: directive.
310 * Made the system semi-navigable in noframes mode.
312 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
313 * Brought over the new room listing code and <G>oto heuristics
314 from the main Citadel tree, to pay attention to floor/room ordering
316 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
317 * Modified the back end of mime_parser to use callbacks instead of
318 doing something specific. Now we can use it elsewhere.
320 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
321 * Fixed the bugs in "Site-wide configuration"
322 * Added a "generic server commands" screen
324 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
325 * Reduced the multiple cookies down to one cookie combining all data.
327 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
328 * Removed wc_host and wc_port cookies.
329 * Added an "edit your session" screen to change your wholisting.
331 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
332 * Added "enter registration"
333 * Set up automatic trigger of Enter Registration when the server
335 * Established that a one-to-one WebCit/Citadel correspondence will
336 be required. No big deal due to shared code segments.
337 * Added "change password"
338 * Added networking configuration screens. These still need testing.
339 * Added a "kill session" link to each line of the wholist when
340 logged in as an aide, and the screens to perform this operation.
342 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
343 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
344 * "Finished" the MIME parser.
345 * Got image uploads working.
346 * Added "add/edit user photo" screens.
347 * Added "add/edit room graphic" screens.

351 Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
352 * Wrote mime_parser.c for handling of image uploads. This will also
353 be used in future Citadel MIME projects.
355 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
356 * Fixed a bug in the room banner display code
357 * Added "delete room"
358 * Added "validate users"
360 Mon Dec 28 00:26:01 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
361 * Added "edit room info file"
364 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
365 * Changed the "auto read new" functionality from a meta refresh tag
366 to an "onload" directive (the former was causing graphics problems)
367 * Added "create room"
370 Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
371 * Got the Zap and List-Zapped commands working
372 * Added a convenience function to display a page with an error string
373 * Automatically do a read-new-msgs whenever a new room banner is loaded

376 * Added the screens to send pages
377 * Changed message headers to display in bigger font, non-boldface
378 * Added the chat system
379 * Added goto private rooms
381 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
382 * Replace "Citadel/UX" in menu bar with the Citadel/UX logo
384 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
385 * automatically regenerate Makefile when Makefile.in changes
387 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
388 * context_loop.c: Moved "remove session" into its own function.
389 Check for dead webcit child process before each transaction.
390 * Ignore SIGPIPE; this seems to magically make the program bulletproof
391 against broken HTTP connections.
392 * Added a housekeeping thread to periodically remove dead sessions
393 and kill idle sessions.
394 * messages.c: added "delete message" functionality
395 * messages.c: added "move message" functionality
396 * userlist.c: added. This adds "userlist" and "show user" functions.

407 * webserver.c: remove commented-out references to SO_LINGER
409 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
410 * context_loop.c: After fork(), child process closes the HTTP socket
411 so when the parent process closes it, it actually _does_ close.
412 Otherwise, aIEeeee and possibly other browsers will hang.
413 * Added support for graphics images retrieved from the Citadel server.
414 * Set up login banner graphic and background image graphic
416 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
417 * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix
419 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
420 * Smoothed out some of the login/logout code. Failed authentication
421 now works the way it should.
422 * Added support for new user login (still need to handle registration).
424 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
425 * Discovered that the HTTP socket problem is related to a socket that
426 isn't properly lingering on close. Temporarily hacked a sleep(10)
427 into context_loop.c until it is figured out.
429 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
430 * Did a little debugging, still trying to figure out why logging in
431 displays "Connection reset by peer" error. It used to work...
