17 * Tagged for the 2.12 release
19 Revision 211.19 2000/05/18 02:33:39 ajc
20 * Don't call whobbs() directly after changing masq room/host, it screws up the
21 refresh. It now calls an HTTP redirect page instead.

24 Revision 211.18 2000/05/08 17:24:32 ajc
25 * Removed HTTP date fields because it was confusing browser caches (weird)

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

102 Revision 1.120 1999/12/12 18:12:28 ajc
103 * get http request: clear hold buffer before starting to read in HTTP request.

130 * Finished the overhaul. Now to tune...
132 Revision 1.111 1999/12/03 17:59:53 ajc
133 * BROKEN BUILD. Wrote most of the session removal code, but some of it is
134 pseudocode so the build is currently broken.
136 Revision 1.110 1999/12/03 16:37:46 ajc
137 * Repaired HTTP output for image transfers and static content
139 Revision 1.109 1999/12/03 05:09:54 ajc
140 * Rewrote the HTTP engine and application coupling to run in a worker thread
141 model and to run as a single multithreaded program (eliminated helper

144 Revision 1.108 1999/12/03 00:18:20 ajc
145 * Added ".c.o" rule to Makefile
147 Revision 1.107 1999/11/26 03:32:59 ajc

166 Revision 1.101 1999/10/06 02:44:02 ajc
167 * Per Nick's request, removed the key bindings stuff. He knows how to fit
168 it back in when it's fixed. Also added more attempts at cache disabling,
169 but it still doesn't work in the StarOffice browser. I don't know why.
171 Revision 1.100 1999/10/02 03:26:14 ajc
172 * Merged in Nick's bit of JavaScript to handle key commands.
173 BROKEN BUILD ALERT!! This runs all the time, even when the cursor is
174 in a text field. Right now you can't even log in.
176 Revision 1.99 1999/09/01 01:06:11 ajc
177 * Added "max message length" field in global config screen
179 Revision 1.98 1999/08/14 18:16:10 ajc

186 Mon Jul 12 23:30:24 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
187 * webcit.c: exit Webcit sessions semi-gracefully when the connection
188 to a Citadel server fails.
189 * messages.c: don't auto-link URL's in messages if it would cause
192 Sat Jul 10 17:51:39 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
193 * Recompiled the Java chat applet using a genuine JDK 1.0.2

204 Wed Jun 23 21:43:30 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
205 * webcit.c: added "back, top, next" buttons to bottom of each page

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

248 * Initial entry to _BASEROOM_ at login now done as a Skip instead
249 of a Goto, in order to prevent it from first marking all msgs old.
251 Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
252 * Replaced _most_ gotoroom() calls with smart_goto(), a version
253 which can differentiate the needs of frames and noframes modes
255 Sat May 8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
256 * webserver.c: added "-t" option to send traces somewhere else
258 Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
259 * context_loop.c: display an error page if the client browser
260 requests a non-root page and there is no cookie set
261 * webserver.c: took my name off the copyright notice (it's a group
264 Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

268 Thu Apr 16 12:00:00 EDT 1999 Nick Grossman <nicl@ulster.net>
269 Changed some output formatting (mainly <FONT> tags).
270 Changed who.c to use urlescputs() rather than escputs()
271 in urls so GOTOs and User Profiles work when the string has a
274 Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
275 http://www.webreference.com/dhtml/column18/menuFrLoad.html
276 How to cause "onLoad=" to cause a sibling frame to refresh without
277 having to use the nonportable HTTP "Window-Target:" directive. Began
278 implementation of this; it should allow portable NS/IE compatibility.
280 Wed Apr 7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
281 * Implemented "access level required to create rooms"
283 Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
284 * webcit.c: modified getz() to *exit* the program when fgets()
285 returns an error. This is actually the desired behavior; it would
286 otherwise busy-loop forever on a broken pipe.
288 Sat Mar 6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
289 * webcit.c: added to getz() the ability to return an error code;
290 implemented this in the main loop, hopefully fixing problems
291 * Added "braindamage" file (frames/JS browser compatibility list)
292 * Added HTTP "User-agent:" detection
293 * wildmat.c, braindamage.c: added
294 * Initial value of 'noframes' is now set by the braindamage check
295 * Ran everything through "indent -kr -i8"
296 * roomops.c: in room list, print a in otherwise empty cells
298 1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
299 * context_loop.c: warning fix
300 * webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)
302 Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
303 * Resolve the name of the connecting host and pass it on to Citadel
305 Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
306 * wDumpContent() is now responsible for </BODY></HTML> most of the
307 time (parameter settable) so that the main menu can easily be
308 embedded in every page when running in noframes mode
309 * noframes mode selection is now carried in the cookie
311 Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
312 * Made the frames stuff less dependent on the HTML TARGET= directive
313 and more dependent on the HTTP Window-target: directive.
314 * Made the system semi-navigable in noframes mode.
316 Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
317 * Brought over the new room listing code and <G>oto heuristics
318 from the main Citadel tree, to pay attention to floor/room ordering
320 Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
321 * Modified the back end of mime_parser to use callbacks instead of
322 doing something specific. Now we can use it elsewhere.
324 Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
325 * Fixed the bugs in "Site-wide configuration"
326 * Added a "generic server commands" screen
328 Fri Jan 8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
329 * Reduced the multiple cookies down to one cookie combining all data.
331 Mon Jan 4 23:04:36 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
332 * Removed wc_host and wc_port cookies.
333 * Added an "edit your session" screen to change your wholisting.
335 Sun Jan 3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
336 * Added "enter registration"
337 * Set up automatic trigger of Enter Registration when the server
339 * Established that a one-to-one WebCit/Citadel correspondence will
340 be required. No big deal due to shared code segments.
341 * Added "change password"
342 * Added networking configuration screens. These still need testing.
343 * Added a "kill session" link to each line of the wholist when
344 logged in as an aide, and the screens to perform this operation.
346 Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
347 * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
348 * "Finished" the MIME parser.
349 * Got image uploads working.
350 * Added "add/edit user photo" screens.
351 * Added "add/edit room graphic" screens.

355 Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
356 * Wrote mime_parser.c for handling of image uploads. This will also
357 be used in future Citadel MIME projects.
359 Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
360 * Fixed a bug in the room banner display code
361 * Added "delete room"
362 * Added "validate users"
364 Mon Dec 28 00:26:01 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

368 Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
369 * Changed the "auto read new" functionality from a meta refresh tag
370 to an "onload" directive (the former was causing graphics problems)
371 * Added "create room"
374 Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
375 * Got the Zap and List-Zapped commands working

380 * Added the screens to send pages
381 * Changed message headers to display in bigger font, non-boldface
382 * Added the chat system
383 * Added goto private rooms
385 Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
386 * Replace "Citadel/UX" in menu bar with the Citadel/UX logo
388 1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
389 * automatically regenerate Makefile when Makefile.in changes
391 Sun Dec 13 13:35:12 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
392 * context_loop.c: Moved "remove session" into its own function.
393 Check for dead webcit child process before each transaction.
394 * Ignore SIGPIPE; this seems to magically make the program bulletproof
395 against broken HTTP connections.
396 * Added a housekeeping thread to periodically remove dead sessions
397 and kill idle sessions.
398 * messages.c: added "delete message" functionality
399 * messages.c: added "move message" functionality
400 * userlist.c: added. This adds "userlist" and "show user" functions.

411 * webserver.c: remove commented-out references to SO_LINGER
413 Wed Dec 9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
414 * context_loop.c: After fork(), child process closes the HTTP socket
415 so when the parent process closes it, it actually _does_ close.
416 Otherwise, aIEeeee and possibly other browsers will hang.
417 * Added support for graphics images retrieved from the Citadel server.
418 * Set up login banner graphic and background image graphic
420 1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>
421 * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix
423 Wed Dec 9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
424 * Smoothed out some of the login/logout code. Failed authentication
425 now works the way it should.
426 * Added support for new user login (still need to handle registration).
428 Tue Dec 8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
429 * Discovered that the HTTP socket problem is related to a socket that
430 isn't properly lingering on close. Temporarily hacked a sleep(10)
431 into context_loop.c until it is figured out.
