2 Revision 211.19 2000/05/18 02:33:39 ajc
3 * Don't call whobbs() directly after changing masq room/host, it screws up the
4 refresh. It now calls an HTTP redirect page instead.

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

113 * Finished the overhaul. Now to tune...
115 Revision 1.111 1999/12/03 17:59:53 ajc
116 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
117 pseudocode so the build is currently broken.
119 Revision 1.110 1999/12/03 16:37:46 ajc
120 * Repaired HTTP output for image transfers and static content
122 Revision 1.109 1999/12/03 05:09:54 ajc
123 * Rewrote the HTTP engine and application coupling to run in a worker thread
124 model and to run as a single multithreaded program (eliminated helper

149 Revision 1.101 1999/10/06 02:44:02 ajc
150 * Per Nick's request, removed the key bindings stuff. He knows how to fit
151 it back in when it's fixed. Also added more attempts at cache disabling,
152 but it still doesn't work in the StarOffice browser. I don't know why.
154 Revision 1.100 1999/10/02 03:26:14 ajc
155 * Merged in Nick's bit of JavaScript to handle key commands.
156 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
157 in a text field. Right now you can't even log in.
159 Revision 1.99 1999/09/01 01:06:11 ajc

171 to a Citadel server fails.
172 * messages.c: don't auto-link URL's in messages if it would cause
175 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
176 * Recompiled the Java chat applet using a genuine JDK 1.0.2

211 Wed Jun 2 23:47:58 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
212 * Ditched the frames mode completely. It wasn't working properly in,
213 among other places, IE 5. Die, Bill, Die.
215 Sat May 29 00:25:47 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
216 * Fixed the behavior of the "forget room" routine, to properly handle
217 the transition back to the Lobby after it's all done.
218 * Added ExpressMessageCat() to allow code to send the user messages
219 along with incoming express messages
220 * WebCit now sends the name of the end user's browser as the client
221 name in a Citadel IDEN command rather than its own name.
223 Fri May 21 23:35:17 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
224 * Minor code cleanups

234 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
235 * Replaced _most_ gotoroom() calls with smart_goto(), a version
236 which can differentiate the needs of frames and noframes modes
238 Sat May 8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
239 * webserver.c: added "-t" option to send traces somewhere else
241 Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
242 * context_loop.c: display an error page if the client browser
243 requests a non-root page and there is no cookie set
244 * webserver.c: took my name off the copyright notice (it's a group
247 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

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

275 * Added HTTP "User-agent:" detection
276 * wildmat.c, braindamage.c: added
277 * Initial value of 'noframes' is now set by the braindamage check
278 * Ran everything through "indent -kr -i8"
279 * roomops.c: in room list, print a in otherwise empty cells
281 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
282 * context_loop.c: warning fix
283 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
285 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
286 * Resolve the name of the connecting host and pass it on to Citadel
288 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
289 * wDumpContent() is now responsible for </BODY></HTML> most of the
290 time (parameter settable) so that the main menu can easily be
291 embedded in every page when running in noframes mode
292 * noframes mode selection is now carried in the cookie
294 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
295 * Made the frames stuff less dependent on the HTML TARGET= directive
296 and more dependent on the HTTP Window-target: directive.
297 * Made the system semi-navigable in noframes mode.
299 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
300 * Brought over the new room listing code and <G>oto heuristics
301 from the main Citadel tree, to pay attention to floor/room ordering
303 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
304 * Modified the back end of mime_parser to use callbacks instead of
305 doing something specific. Now we can use it elsewhere.
307 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
308 * Fixed the bugs in "Site-wide configuration"

311 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
312 * Reduced the multiple cookies down to one cookie combining all data.
314 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
315 * Removed wc_host and wc_port cookies.
316 * Added an "edit your session" screen to change your wholisting.
318 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
319 * Added "enter registration"
320 * Set up automatic trigger of Enter Registration when the server
322 * Established that a one-to-one WebCit/Citadel correspondence will
323 be required. No big deal due to shared code segments.
324 * Added "change password"
325 * Added networking configuration screens. These still need testing.
326 * Added a "kill session" link to each line of the wholist when
327 logged in as an aide, and the screens to perform this operation.
329 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
330 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
331 * "Finished" the MIME parser.
332 * Got image uploads working.

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

352 * Changed the "auto read new" functionality from a meta refresh tag
353 to an "onload" directive (the former was causing graphics problems)

366 * Added goto private rooms
368 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
369 * Replace "Citadel/UX" in menu bar with the Citadel/UX logo
371 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
372 * automatically regenerate Makefile when Makefile.in changes
374 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
375 * context_loop.c: Moved "remove session" into its own function.
376 Check for dead webcit child process before each transaction.
377 * Ignore SIGPIPE; this seems to magically make the program bulletproof
378 against broken HTTP connections.
379 * Added a housekeeping thread to periodically remove dead sessions
380 and kill idle sessions.
381 * messages.c: added "delete message" functionality
382 * messages.c: added "move message" functionality

396 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
397 * context_loop.c: After fork(), child process closes the HTTP socket
398 so when the parent process closes it, it actually _does_ close.
399 Otherwise, aIEeeee and possibly other browsers will hang.
400 * Added support for graphics images retrieved from the Citadel server.
401 * Set up login banner graphic and background image graphic
403 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
404 * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix
406 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

408 now works the way it should.
409 * Added support for new user login (still need to handle registration).
411 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
412 * Discovered that the HTTP socket problem is related to a socket that
413 isn't properly lingering on close. Temporarily hacked a sleep(10)
414 into context_loop.c until it is figured out.
416 Mon Dec 7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
417 * Did a little debugging, still trying to figure out why logging in
418 displays "Connection reset by peer" error. It used to work...
420 1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
421 * Makefile.in: updated dependencies
423 Sun Dec 6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
