Revision 210.0  1999/12/24 04:57:18  ajc
* 2.10 release

Revision 1.121  1999/12/23 04:54:48  ajc

* Removed overly verbose logging

Revision 1.120  1999/12/12 18:12:28  ajc

Revision 1.117  1999/12/06 03:40:29  ajc
* Moved a bunch of other global variables to per-session variables

Revision 1.116  1999/12/06 02:05:33  ajc

Revision 1.111  1999/12/03 17:59:53  ajc
* BROKEN BUILD.  Wrote most of the session removal code, but some of it is
  pseudocode so the build is currently broken.

* Repaired HTTP output for image transfers and static content

Revision 1.109  1999/12/03 05:09:54  ajc
* Rewrote the HTTP engine and application coupling to run in a worker thread

  processes and pipes).  It currently runs but has many large bugs.

Revision 1.108  1999/12/03 00:18:20  ajc
* Added ".c.o" rule to Makefile

Revision 1.107  1999/11/26 03:32:59  ajc

* Minor bug fix in registration screen

Revision 1.101  1999/10/06 02:44:02  ajc
* Per Nick's request, removed the key bindings stuff.  He knows how to fit
  it back in when it's fixed.  Also added more attempts at cache disabling,
  but it still doesn't work in the StarOffice browser.  I don't know why.

Revision 1.100  1999/10/02 03:26:14  ajc
* Merged in Nick's bit of JavaScript to handle key commands.
  BROKEN BUILD ALERT!!  This runs all the time, even when the cursor is
  in a text field.  Right now you can't even log in.

Revision 1.99  1999/09/01 01:06:11  ajc
* Added "max message length" field in global config screen

Mon May 10 23:09:34 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Replaced _most_ gotoroom() calls with smart_goto(), a version
	  which can differentiate the needs of frames and noframes modes

Sat May  8 01:07:06 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* webserver.c: added "-t" option to send traces somewhere else

Tue Apr 27 23:36:35 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

Wed Apr 14 17:56:18 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	http://www.webreference.com/dhtml/column18/menuFrLoad.html
	How to cause "onLoad=" to cause a sibling frame to refresh without
	having to use the nonportable HTTP "Window-Target:" directive.  Began
	implementation of this; it should allow portable NS/IE compatibility.

Wed Apr  7 21:51:33 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Implemented "access level required to create rooms"

	* webcit.c: modified getz() to *exit* the program when fgets()
	  returns an error.  This is actually the desired behavior; it would
	  otherwise busy-loop forever on a broken pipe.

Sat Mar  6 19:56:07 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* webcit.c: added to getz() the ability to return an error code;
	  implemented this in the main loop, hopefully fixing problems

1999-02-24 Nathan Bryant <bryant@cs.usm.maine.edu>
	* context_loop.c: warning fix
	* webcit.c: off_t is a 64-bit `long long' on BSDI (eek!)

Sat Jan 30 19:00:58 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Resolve the name of the connecting host and pass it on to Citadel

Fri Jan 29 14:49:49 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* wDumpContent() is now responsible for </BODY></HTML> most of the
	  time (parameter settable) so that the main menu can easily be
	  embedded in every page when running in noframes mode
	* noframes mode selection is now carried in the cookie

Thu Jan 28 20:30:08 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

	  from the main Citadel tree, to pay attention to floor/room ordering

Thu Jan 14 17:14:11 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Modified the back end of mime_parser to use callbacks instead of
	  doing something specific.  Now we can use it elsewhere.

Mon Jan 11 21:53:16 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Fixed the bugs in "Site-wide configuration"
	* Added a "generic server commands" screen

Fri Jan  8 22:20:54 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

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

Sun Jan  3 20:05:31 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Added "enter registration"
	* Set up automatic trigger of Enter Registration when the server
	  says it's needed
	* Established that a one-to-one WebCit/Citadel correspondence will
	  be required.  No big deal due to shared code segments.
	* Added "change password"
	* Added networking configuration screens.  These still need testing.
	* Added a "kill session" link to each line of the wholist when
	  logged in as an aide, and the screens to perform this operation.

Thu Dec 31 21:53:20 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>

	* context_loop.c: Moved "remove session" into its own function.
	  Check for dead webcit child process before each transaction.
	* Ignore SIGPIPE; this seems to magically make the program bulletproof
	  against broken HTTP connections.
	* Added a housekeeping thread to periodically remove dead sessions
	  and kill idle sessions.
	* messages.c: added "delete message" functionality
	* messages.c: added "move message" functionality

Wed Dec  9 18:50:46 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* context_loop.c: After fork(), child process closes the HTTP socket

	  Otherwise, aIEeeee and possibly other browsers will hang.
	* Added support for graphics images retrieved from the Citadel server.
	* Set up login banner graphic and background image graphic

1998-12-09 Nathan Bryant <bryant@cs.usm.maine.edu>

Tue Dec  8 15:45:42 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Discovered that the HTTP socket problem is related to a socket that
	  isn't properly lingering on close.  Temporarily hacked a sleep(10)
	  into context_loop.c until it is figured out.

Mon Dec  7 17:03:18 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
	* Did a little debugging, still trying to figure out why logging in

	* context_loop.c: warning fix

1998-12-05 Nathan Bryant <bryant@cs.usm.maine.edu>
