106 Revision 1.111 1999/12/03 17:59:53 ajc
107 * BROKEN BUILD. Wrote most of the session removal code, but some of it is

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

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

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

229 Sat May 8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
230 * webserver.c: added "-t" option to send traces somewhere else
232 Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

243 Changed some output formatting (mainly <FONT> tags).
244 Changed who.c to use urlescputs() rather than escputs()
245 in urls so GOTOs and User Profiles work when the string has a
248 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
249 http://www.webreference.com/dhtml/column18/menuFrLoad.html
250 How to cause "onLoad=" to cause a sibling frame to refresh without
251 having to use the nonportable HTTP "Window-Target:" directive. Began
252 implementation of this; it should allow portable NS/IE compatibility.
254 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
255 * Implemented "access level required to create rooms"
257 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
258 * webcit.c: modified getz() to *exit* the program when fgets()
259 returns an error. This is actually the desired behavior; it would
260 otherwise busy-loop forever on a broken pipe.
262 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
263 * webcit.c: added to getz() the ability to return an error code;

272 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
273 * context_loop.c: warning fix
274 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
276 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
277 * Resolve the name of the connecting host and pass it on to Citadel
279 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
280 * wDumpContent() is now responsible for </BODY></HTML> most of the
281 time (parameter settable) so that the main menu can easily be
282 embedded in every page when running in noframes mode
283 * noframes mode selection is now carried in the cookie
285 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
286 * Made the frames stuff less dependent on the HTML TARGET= directive
287 and more dependent on the HTTP Window-target: directive.
288 * Made the system semi-navigable in noframes mode.
290 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

292 from the main Citadel tree, to pay attention to floor/room ordering
294 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
295 * Modified the back end of mime_parser to use callbacks instead of
296 doing something specific. Now we can use it elsewhere.
298 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
299 * Fixed the bugs in "Site-wide configuration"

310 * Added "enter registration"
311 * Set up automatic trigger of Enter Registration when the server
313 * Established that a one-to-one WebCit/Citadel correspondence will
314 be required. No big deal due to shared code segments.
315 * Added "change password"
316 * Added networking configuration screens. These still need testing.
317 * Added a "kill session" link to each line of the wholist when
318 logged in as an aide, and the screens to perform this operation.
320 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

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

362 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
363 * automatically regenerate Makefile when Makefile.in changes
365 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
366 * context_loop.c: Moved "remove session" into its own function.
367 Check for dead webcit child process before each transaction.
368 * Ignore SIGPIPE; this seems to magically make the program bulletproof
369 against broken HTTP connections.
370 * Added a housekeeping thread to periodically remove dead sessions
371 and kill idle sessions.
372 * messages.c: added "delete message" functionality
373 * messages.c: added "move message" functionality

387 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
388 * context_loop.c: After fork(), child process closes the HTTP socket
389 so when the parent process closes it, it actually _does_ close.
390 Otherwise, aIEeeee and possibly other browsers will hang.
391 * Added support for graphics images retrieved from the Citadel server.
392 * Set up login banner graphic and background image graphic
394 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

402 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
403 * Discovered that the HTTP socket problem is related to a socket that
404 isn't properly lingering on close. Temporarily hacked a sleep(10)
405 into context_loop.c until it is figured out.
407 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
408 * Did a little debugging, still trying to figure out why logging in
409 displays "Connection reset by peer" error. It used to work...
411 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
412 * Makefile.in: updated dependencies
414 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
