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

120 Revision 1.101 1999/10/06 02:44:02 ajc
121 * Per Nick's request, removed the key bindings stuff. He knows how to fit
122 it back in when it's fixed. Also added more attempts at cache disabling,
123 but it still doesn't work in the StarOffice browser. I don't know why.
125 Revision 1.100 1999/10/02 03:26:14 ajc
126 * Merged in Nick's bit of JavaScript to handle key commands.
127 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
128 in a text field. Right now you can't even log in.

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

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

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

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

223 Changed some output formatting (mainly <FONT> tags).
224 Changed who.c to use urlescputs() rather than escputs()
225 in urls so GOTOs and User Profiles work when the string has a
228 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
229 http://www.webreference.com/dhtml/column18/menuFrLoad.html
230 How to cause "onLoad=" to cause a sibling frame to refresh without
231 having to use the nonportable HTTP "Window-Target:" directive. Began
232 implementation of this; it should allow portable NS/IE compatibility.
234 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
235 * Implemented "access level required to create rooms"
237 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
238 * webcit.c: modified getz() to *exit* the program when fgets()
239 returns an error. This is actually the desired behavior; it would
240 otherwise busy-loop forever on a broken pipe.
242 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
243 * webcit.c: added to getz() the ability to return an error code;
244 implemented this in the main loop, hopefully fixing problems

246 * Added HTTP "User-agent:" detection
247 * wildmat.c, braindamage.c: added

252 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
253 * context_loop.c: warning fix
254 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
256 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
257 * Resolve the name of the connecting host and pass it on to Citadel
259 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
260 * wDumpContent() is now responsible for </BODY></HTML> most of the
261 time (parameter settable) so that the main menu can easily be
262 embedded in every page when running in noframes mode
263 * noframes mode selection is now carried in the cookie
265 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
266 * Made the frames stuff less dependent on the HTML TARGET= directive
267 and more dependent on the HTTP Window-target: directive.
268 * Made the system semi-navigable in noframes mode.
270 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
271 * Brought over the new room listing code and <G>oto heuristics
272 from the main Citadel tree, to pay attention to floor/room ordering
274 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
275 * Modified the back end of mime_parser to use callbacks instead of
276 doing something specific. Now we can use it elsewhere.
278 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
279 * Fixed the bugs in "Site-wide configuration"

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

290 * Added "enter registration"
291 * Set up automatic trigger of Enter Registration when the server
293 * Established that a one-to-one WebCit/Citadel correspondence will
294 be required. No big deal due to shared code segments.
295 * Added "change password"
296 * Added networking configuration screens. These still need testing.
297 * Added a "kill session" link to each line of the wholist when
298 logged in as an aide, and the screens to perform this operation.

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

342 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
343 * automatically regenerate Makefile when Makefile.in changes
345 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
346 * context_loop.c: Moved "remove session" into its own function.
347 Check for dead webcit child process before each transaction.
348 * Ignore SIGPIPE; this seems to magically make the program bulletproof
349 against broken HTTP connections.
350 * Added a housekeeping thread to periodically remove dead sessions
351 and kill idle sessions.
352 * messages.c: added "delete message" functionality
353 * messages.c: added "move message" functionality

367 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
368 * context_loop.c: After fork(), child process closes the HTTP socket
369 so when the parent process closes it, it actually _does_ close.
370 Otherwise, aIEeeee and possibly other browsers will hang.
371 * Added support for graphics images retrieved from the Citadel server.
372 * Set up login banner graphic and background image graphic
374 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

379 now works the way it should.
380 * Added support for new user login (still need to handle registration).
382 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
383 * Discovered that the HTTP socket problem is related to a socket that
384 isn't properly lingering on close. Temporarily hacked a sleep(10)
385 into context_loop.c until it is figured out.
387 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
388 * Did a little debugging, still trying to figure out why logging in
389 displays "Connection reset by peer" error. It used to work...
391 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
392 * Makefile.in: updated dependencies
394 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
