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

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

156 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
157 * Fixed the behavior of the "forget room" routine, to properly handle
158 the transition back to the Lobby after it's all done.
159 * Added ExpressMessageCat() to allow code to send the user messages
160 along with incoming express messages
161 * WebCit now sends the name of the end user's browser as the client

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

194 Changed who.c to use urlescputs() rather than escputs()
195 in urls so GOTOs and User Profiles work when the string has a
198 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
199 http://www.webreference.com/dhtml/column18/menuFrLoad.html
200 How to cause "onLoad=" to cause a sibling frame to refresh without
201 having to use the nonportable HTTP "Window-Target:" directive. Began
202 implementation of this; it should allow portable NS/IE compatibility.
204 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
205 * Implemented "access level required to create rooms"
207 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
208 * webcit.c: modified getz() to *exit* the program when fgets()
209 returns an error. This is actually the desired behavior; it would
210 otherwise busy-loop forever on a broken pipe.
212 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
213 * webcit.c: added to getz() the ability to return an error code;

222 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
223 * context_loop.c: warning fix
224 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
226 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
227 * Resolve the name of the connecting host and pass it on to Citadel
229 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
230 * wDumpContent() is now responsible for </BODY></HTML> most of the
231 time (parameter settable) so that the main menu can easily be
232 embedded in every page when running in noframes mode
233 * noframes mode selection is now carried in the cookie
235 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
236 * Made the frames stuff less dependent on the HTML TARGET= directive
237 and more dependent on the HTTP Window-target: directive.
238 * Made the system semi-navigable in noframes mode.
240 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
241 * Brought over the new room listing code and <G>oto heuristics
242 from the main Citadel tree, to pay attention to floor/room ordering
244 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
245 * Modified the back end of mime_parser to use callbacks instead of
246 doing something specific. Now we can use it elsewhere.
248 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
249 * Fixed the bugs in "Site-wide configuration"

256 * Removed wc_host and wc_port cookies.
257 * Added an "edit your session" screen to change your wholisting.

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

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

313 * automatically regenerate Makefile when Makefile.in changes
315 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
316 * context_loop.c: Moved "remove session" into its own function.
317 Check for dead webcit child process before each transaction.
318 * Ignore SIGPIPE; this seems to magically make the program bulletproof
319 against broken HTTP connections.
320 * Added a housekeeping thread to periodically remove dead sessions
321 and kill idle sessions.
322 * messages.c: added "delete message" functionality
323 * messages.c: added "move message" functionality

337 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
338 * context_loop.c: After fork(), child process closes the HTTP socket
339 so when the parent process closes it, it actually _does_ close.
340 Otherwise, aIEeeee and possibly other browsers will hang.
341 * Added support for graphics images retrieved from the Citadel server.
342 * Set up login banner graphic and background image graphic
344 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

349 now works the way it should.
350 * Added support for new user login (still need to handle registration).
352 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
353 * Discovered that the HTTP socket problem is related to a socket that
354 isn't properly lingering on close. Temporarily hacked a sleep(10)
355 into context_loop.c until it is figured out.
357 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
358 * Did a little debugging, still trying to figure out why logging in
359 displays "Connection reset by peer" error. It used to work...
361 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
362 * Makefile.in: updated dependencies
364 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
