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

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

206 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
207 * Ditched the frames mode completely. It wasn't working properly in,

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

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

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

238 requests a non-root page and there is no cookie set
239 * webserver.c: took my name off the copyright notice (it's a group
242 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

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

276 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
277 * context_loop.c: warning fix
278 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
280 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
281 * Resolve the name of the connecting host and pass it on to Citadel
283 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
284 * wDumpContent() is now responsible for </BODY></HTML> most of the
285 time (parameter settable) so that the main menu can easily be
286 embedded in every page when running in noframes mode
287 * noframes mode selection is now carried in the cookie
289 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
290 * Made the frames stuff less dependent on the HTML TARGET= directive
291 and more dependent on the HTTP Window-target: directive.
292 * Made the system semi-navigable in noframes mode.
294 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
295 * Brought over the new room listing code and <G>oto heuristics
296 from the main Citadel tree, to pay attention to floor/room ordering
298 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
299 * Modified the back end of mime_parser to use callbacks instead of
300 doing something specific. Now we can use it elsewhere.
302 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
303 * Fixed the bugs in "Site-wide configuration"

306 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
307 * Reduced the multiple cookies down to one cookie combining all data.

310 * Removed wc_host and wc_port cookies.
311 * Added an "edit your session" screen to change your wholisting.
313 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
314 * Added "enter registration"
315 * Set up automatic trigger of Enter Registration when the server
317 * Established that a one-to-one WebCit/Citadel correspondence will
318 be required. No big deal due to shared code segments.
319 * Added "change password"
320 * Added networking configuration screens. These still need testing.
321 * Added a "kill session" link to each line of the wholist when
322 logged in as an aide, and the screens to perform this operation.
324 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

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

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

391 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
392 * context_loop.c: After fork(), child process closes the HTTP socket
393 so when the parent process closes it, it actually _does_ close.
394 Otherwise, aIEeeee and possibly other browsers will hang.
395 * Added support for graphics images retrieved from the Citadel server.
396 * Set up login banner graphic and background image graphic
398 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

403 now works the way it should.
404 * Added support for new user login (still need to handle registration).
406 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
407 * Discovered that the HTTP socket problem is related to a socket that
408 isn't properly lingering on close. Temporarily hacked a sleep(10)
409 into context_loop.c until it is figured out.
411 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
412 * Did a little debugging, still trying to figure out why logging in
413 displays "Connection reset by peer" error. It used to work...
415 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
416 * Makefile.in: updated dependencies
418 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
