Revision 505.6  2004/02/26 03:07:26  ajc
* Put the /favicon.ico --> /static/favicon.ico hack back in.  Why not?

Revision 505.5  2004/02/25 23:10:28  ajc
* Allow "/do_logout" as a no-frames page

Revision 505.4  2004/02/25 23:00:21  ajc
* Changed the favicon support to LINK tags in the HEAD of static stuff,
  to make life easier.  (Thanks to prosthetik for this)

Revision 505.3  2004/02/25 15:20:11  ajc
* Support for favicon.ico in the static/ directory

Revision 505.2  2004/02/24 04:06:42  ajc
* Changed the colors slightly in chat screen

Revision 505.1  2004/02/20 06:07:06  ajc
* Replaced the Java chat with a new system based on IFRAME's and JavaScript

Revision 505.0  2004/02/19 03:32:50  ajc
* THIS IS 5.05

* Changed the internal version number to 5.05
* Completed the frames fix

Revision 504.6  2004/02/18 20:08:29  ajc
* Fixed the frameset force reload logic.  Now it does the whole frameset
  without displaying an error in the main frame.

Revision 504.5  2004/02/18 19:17:51  ajc
* Force reload of frameset if someone tries to escape it.  Not perfect
  but it mostly works at this poing.

Revision 504.4  2004/02/17 03:37:11  ajc
* Indicate to Citadel that we want Server Generated Invitations when
  calendar events are saved.  (No longer the default in Citadel server.)

* Prepare for a way to avoid falling out of the main frameset

Revision 504.2  2004/02/09 03:37:57  ajc
* Changed the thread pool management algorithm.  Detecting idle time between
  socket accepts was not working reliably on all systems, so we now follow
  the same algorithm as the Citadel server (spawn more threads when number
  of sessions < number of threads, but keep constrained to pre-defined
  minimum and maximum thread count)

Revision 504.1  2004/02/03 03:09:51  ajc

* iconbar.c: removed a stray character or two...

Revision 501.0  2003/10/21 04:26:37  ajc

* Finished prettying up the vCard display

Revision 500.28  2003/10/17 02:31:45  ajc
* Multi-line string literals are deprecated in GCC 3.1 unless each line
  is wrapped in quotes.  Performed this fix so it'll compile.
* setup.c: removed references to unused variable tempfile[]

Revision 500.27  2003/10/09 03:17:02  ajc

  and added a meta-menu

Revision 500.23  2003/08/24 03:31:50  ajc
* Finished the setup program
* Bumped the internal version number to 5.01

Revision 500.22  2003/08/22 00:47:27  ajc

Revision 500.21  2003/08/22 00:25:40  ajc

Revision 500.20  2003/08/20 03:48:55  ajc

* Minimum required Citadel is now 6.11

* Clicking on an address in a vCard now connects to WebCit mail instead
  of a browser mailto: link

Revision 500.18  2003/08/19 04:18:43  ajc

  more clickable and better looking...

* messages.c: fix off-by-one-error in selector bar

Revision 500.16  2003/08/07 22:18:03  ajc
* Add the Summary Page to the customizable iconbar

Revision 500.15  2003/08/07 03:51:51  ajc
* Customizable icon bar as: pictures and text, pictures, text

Revision 500.14  2003/08/05 03:52:14  ajc
* First working version of the customizable iconbar.  It contains a basic
  set of options and now automatically refreshes when it's customized.

Revision 500.13  2003/08/04 03:50:29  ajc
* First cut at the customizable iconbar is done.  A bunch of generic options
  are there.  Still need to get the actual iconbar to refresh when changes
  are made.

Revision 500.12  2003/08/03 21:02:01  ajc
* More work on customizable iconbar

Revision 500.11  2003/08/02 05:25:46  ajc

* Add config.c_purge_hour to config screen

Revision 500.9  2003/07/06 22:06:59  ajc
* When converting "anything that looks like a URL" to a real link, first
  make sure that it isn't already inside a link.  This fixes most of the
  long, ugly URL strings sent by eBay.
* Automatically dismantle mailto: links in HTML messages, and convert
  them to WebCit mail links (clicking on it sends the user to the Mail
  room and begins composing a new message with the recipient and subject
  fields pre-populated).

Revision 500.8  2003/06/29 20:51:21  ajc
* Worked around a rendering bug in Satan's Browser that was causing it
  to draw the calendar month view much wider than the actual screen wdith

Revision 500.7  2003/06/28 04:09:37  error
* roomops.c: Backout change to display one less box in the first column in
  roomlist view, it doesn't seem to work for everyone

Revision 500.6  2003/06/28 03:52:51  error

Revision 500.4  2003/06/26 03:37:58  ajc
* Allow anonymous HTTP requests for /freebusy/user%20name.vcf (or .vfb)
  This will allow some groupware clients to browse the free/busy times of
  other users on the system.

Revision 500.3  2003/06/21 05:17:21  ajc
* Better alignment of system messages
* Exterminated display_error() and replaced it with WC->ImportantMessage
  which is displayed in a bubble on top of whatever page you're on next.

* Fixed some nesting problems in output_headers()

Revision 500.2  2003/06/20 03:39:27  ajc
* Optimization to floor layout in box view

Revision 500.1  2003/06/20 03:04:26  ajc
* "Reply" button on messages now handles IGnet recipients correctly

Revision 500.0  2003/06/10 04:23:08  ajc
* THIS IS 5.00

Revision 410.50  2003/06/10 04:22:58  ajc
* Updated docs and headers for 5.00 release

Revision 410.49  2003/06/10 04:05:23  ajc
* De-tabled the left side icon bar and reduced one of the graphics, so
  that all of the rounded corners show up in Satan's Browser.

Revision 410.48  2003/06/10 03:47:41  ajc
* style.css: added font selection to default <BODY> tag

Revision 410.47  2003/06/06 03:26:03  ajc
* Satan's Browser insists on putting bloody acres of whitespace to the
  right of any bulleted list items, making any multi-column table containing
  a list take more than the entire screen.  Removed all such lists so it
  looks ok.  If you are reading this and you are a Microsoft employee, please
  commit suicide before you break anything else.

Revision 410.46  2003/06/06 02:22:07  ajc
* Changed the upper left and upper right bounded box corners to a solid
  blue (#204B78) instead of gradiated, because it was looking funny in
  256-color mode.  It also looked funny in Internet Explorer, but people
  who use Internet Explorer are contributing to terrorism and really don't
  deserve Web access in the first place.  So I really just fixed this to make
  it look good in 256-color Netscape.

Revision 410.45  2003/06/05 21:37:37  ajc
* Cosmetic changes.  Attempting to fix b0rken rendering of main menu
  in b0rken IE browser.  Die, Bill, Die.

Revision 410.44  2003/06/05 03:52:29  ajc
* Buncha cosmetic changes

Revision 410.43  2003/06/04 03:41:25  ajc

  smaller images.

Revision 410.41  2003/05/31 21:36:45  ajc
* Cosmetic changes

Revision 410.40  2003/05/26 21:05:42  ajc
* availability.c: brought over ical_ctdl_is_overlap() from Citadel.  Used
  it to complete the free/busy checking for attendee availability.

Revision 410.39  2003/05/26 05:44:45  ajc
* event.c: fix compiler warning

Revision 410.38  2003/05/26 05:39:46  ajc
* webcit.h: change minimum required Citadel server to 6.07 due to FREEBUSY
  bug fixed in Citadel.

Revision 410.37  2003/05/26 05:28:13  ajc
* serv_func.c: added utility function read_server_text()
* availability.c: banged out more of this code -- still not complete

Revision 410.36  2003/05/26 03:28:02  ajc
* Getting closer to doing the availability check.  Created new source
  module 'availability.c' for this purpose.  Stub function is in place.

Revision 410.35  2003/05/25 04:25:12  ajc
* siteconfig.c: fixed a spelling error
* event.c: add a "Check attendee availability" button, and the code to
  bypass saving the event to the server, do something with it, and then
  feed the twiddled data structure back to the form display function for
  further editing.  What's still missing is the code to do the actual
  availability check.

Revision 410.34  2003/05/24 22:22:35  ajc
* Small stylesheet hack to make it work with b0rken IE

Revision 410.33  2003/05/24 22:13:08  ajc
* Changed the login banner a bit

Revision 410.32  2003/05/20 03:25:41  ajc
* Separate event invitees with newlines instead of commas.

Revision 410.31  2003/05/19 19:55:09  ajc
* summary.c: eliminate compiler warnings about unused variables when
  compiling a WebCit service without calendar support

Revision 410.30  2003/05/18 02:05:33  ajc
* More conversion of screens to the new look-and-feel.

Revision 410.29  2003/05/16 04:11:29  ajc
* We don't need no steenking workaround.  Problem fixed.  MIME parser not
  broken.  Web server was calling it with bad parameters.  All fixed now.
* Slightly tweaked the look of the tabs in the room edit screen.  Still looks
  like crap.

Revision 410.28  2003/05/15 04:52:26  ajc
* Minor workaround in web forms to handle mime parser problem in uploads

Revision 410.27  2003/05/15 03:35:59  ajc

Revision 410.26  2003/05/14 03:46:35  ajc
* More background cleanup

Revision 410.25  2003/05/05 17:19:46  ajc
* Cleanups to summary page when running on a non ical enabled system
* Use non breaking spaces in summary page box titles

Revision 410.24  2003/05/04 04:22:41  ajc
* Display body of messages on a white background.  I am doing this in order
  to prepare for making the general background of the screen a darker color.

Revision 410.23  2003/05/04 02:54:55  ajc
* Summary page now uses our cutesy new rounded window boxes

Revision 410.22  2003/05/03 21:28:41  ajc
* Added in a slick new box style and put the room lists in it

Revision 410.21  2003/05/03 16:57:04  ajc
* In the 'folders' and 'portal' views, change the folder delimiter
  from / to \ to avoid conflict with room names that have slashes

Revision 410.20  2003/05/03 16:23:29  ajc
* Enforce three columns in portal view of room list

Revision 410.19  2003/05/03 04:52:32  ajc
* Added an experimental new "portal view" to the room list options

Revision 410.18  2003/05/02 03:23:41  ajc
* Minor change to room list algorithm

Revision 410.17  2003/05/01 15:33:05  ajc
* Fixed a potential memory leak in enumeration of MIME parts

* When static content is requested, fetch it without trying to connect
  to Citadel first.

Revision 410.15  2003/04/30 05:00:00  ajc
* Added the ability to compose messages with file attachments uploaded from
  the browser

Revision 410.14  2003/04/27 04:46:02  ajc
* Replace LKRN/LKRO in "folders view" room list with a single LKRA that
  observes the flag designating the presence of new messages.  (The "rooms
  view" uses an LKRN/LKRO pair *per floor* and has the same inefficiency,
  but that view may get axed soon.)

Revision 410.13  2003/04/26 21:57:53  ajc
* tcp_sockets.c: when an outgoing socket connection fails, close the socket
  before returning an error code to avoid a file descriptor leak

Revision 410.12  2003/04/19 21:42:36  ajc
* Repaired all my b0rken COLOR tags
* Replaced most FONT tags with SPAN tags
* Added new styles

Revision 410.11  2003/04/19 19:58:10  ajc
* Lots of great changes from Nick to make the site CSS-enabled.

Revision 410.10  2003/04/14 04:04:40  ajc
* First cut of CSS-izing WebCit.  Probably b0rken.

Revision 410.9  2003/04/09 04:02:32  ajc
* Remove the defaulthost/defaultport vs. c_host/c_port stuff -- we haven't
  supported the idea of one WebCit connecting to multiple Citadels for a
  long time.  Now it's just one set of variables, called ctdlhost/ctdlport.
* When connecting to Citadel through a Unix domain socket, don't try to make
  the Java chat applet available.

Revision 410.8  2003/03/31 03:32:19  ajc
* messages.c: check for 000 terminator while parsing RFC822 headers to
  prevent getting hung up while displaying certain badly formatted messages.

Revision 410.7  2003/03/30 06:13:19  ajc
* When reading from the server, do not treat CR as end-of-line because
  there's probably an LF coming after it.  Instead, keep reading to the LF
  and then strip both.
* No not underline links in the icon bars

Revision 410.6  2003/03/17 04:17:41  ajc
* Call to accept() was being made with an uninitialized variable for the
  third argument.  Changed the second and third argument to NULL and 0 because
  we don't really need accept() to fill up a buffer full of information that
  we'll never use.  (Thanks to SteveV for reporting the bug and helping to
  troubleshoot it.)
* Removed the mutex wrapper around select() because we don't need it.  All
  idle worker threads now block on select() and one of them will wake up when
  a connection arrives.

Revision 410.5  2003/03/15 20:55:03  ajc
* When a requested image is not available on the Citadel server, send a
  1x1 transparent GIF instead of 404 error.

Revision 410.4  2003/03/14 04:21:57  ajc
* clone events to be encapsulated before saving, because the original
  instance may already have a parent, and that makes crashy crashy

Revision 410.3  2003/03/13 05:57:17  ajc
* More encapsulation.  Warning: there are bugs in this!!

Revision 410.2  2003/03/13 05:20:23  ajc
* Various changes to the calendar service to handle messages containing
  fully encapsulated VCALENDAR components instead of only unencapsulated
  VEVENT subcomponents.  We have to move in this direction for compatibility
  with other products.

Revision 410.1  2003/03/01 22:07:19  ajc
* New user registration, as well as existing user re-registration, now
  uses the vCard editing screen.
* Administratively editing users' address book entries now works again,
  mainly due to a fix in the Citadel server.  Now requiring Citadel 6.06
  in order to enforce this.

Revision 410.0  2003/02/19 03:49:33  ajc
* THIS IS 4.10

Revision 400.90  2003/02/19 03:49:17  ajc
* latest config.guess and config.sub from www.gnu.org

Revision 400.89  2003/02/07 04:44:17  ajc
* Replaced sleep() with a function that sleeps using select() in order to
  avoid potential issues with SIGALRM.  Possible fix for weird behavior
  when running on a Macintosh.

Revision 400.88  2003/01/29 22:32:07  ajc
* Shuffled some code and comments around; minor cleanup

Revision 400.87  2003/01/28 15:37:12  ajc
* All functions which read binary data from the server now make use of the
  read_server_binary() function in tools.c
* Binary reads from server now have safety code to prevent infinite loops
* All output of MIME objects is now done with http_transmit_thing()

Revision 400.86  2003/01/19 06:28:04  ajc
* Minimum required Citadel version 6.05

Revision 400.85  2003/01/16 04:41:26  ajc
* When displaying edit controls for time of day in the calendar, only show
  minutes that are multiples of 5 ... unless the existing value is not a
  multiple of 5, in which case we show that too.

Revision 400.84  2003/01/15 17:34:04  ajc
* event.c: fixed a misspelling
* config.guess, config.sub: updated using latest from ftp.gnu.org

Revision 400.83  2003/01/14 04:21:27  ajc
* Only offer views which make sense for the default view of a room

Revision 400.82  2003/01/13 03:34:33  ajc
* Get ready for the 4.10 release

Revision 400.81  2003/01/12 23:22:53  ajc

Revision 400.80  2003/01/07 04:56:17  ajc
* Complete the free/busy transparency handling in the form
* Default times for new events are now in the correct timezone

Revision 400.79  2003/01/06 18:01:35  ajc
* Begin handling of TRANSP property to show event times as free or
  busy (not finished).

Revision 400.78  2003/01/05 21:02:14  ajc
* Summary page: three columns are now all the same width

Revision 400.77  2003/01/05 20:56:05  ajc
* minor fix for previous checkin

Revision 400.76  2003/01/05 20:51:01  ajc

Revision 400.75  2003/01/05 05:01:00  ajc
* Add "today's calendar events" to the summary page.

Revision 400.74  2003/01/05 04:27:28  ajc
* Add "Tasks" to the summary page

Revision 400.73  2002/12/28 05:44:09  ajc
* ical_dezonify.c: brought over new version from the Citadel source (again)

Revision 400.72  2002/12/28 05:12:45  ajc
* ical_dezonify.c: brought over new version from the Citadel source.

Revision 400.71  2002/12/26 04:04:48  ajc
* Perform CHEK command when automatically establishing sessions, not just
  when one is explicitly created.  Some stuff is missing otherwise.

Revision 400.70  2002/12/25 23:18:06  ajc
* Be more strategic about when to call ical_dezonify()
  (This may be the last set of fixes.  I hope so.)

Revision 400.69  2002/12/25 21:39:38  ajc
* ical_dezonify.c: added.
* calendar.c: convert incoming ical messages to UTC
  (the usual routines will then convert them to local time for display)

Revision 400.68  2002/12/25 07:06:00  ajc
* Tweaked the code to work with libical 0.24

Revision 400.67  2002/12/20 04:50:00  ajc
* When saving a calendar event, increment the SEQUENCE property.

Revision 400.66  2002/12/18 05:03:39  ajc
* In the calendar code, changed all "struct tm *" to "struct tm" and changed
  all "tm = localtime(foo)" to "memcpy(&tm, localtime(foo), sizeof(struct tm))"
  Because the libc-allocated buffer was getting clobbered.

Revision 400.63  2002/12/15 05:50:59  ajc
* Form editing of date/time fields now assumes that the icaltimetype being

  as the organizer of new events.  Detect when the user is the organizer and
  enable/disable the attendees box accordingly.

Revision 400.57  2002/11/29 16:38:37  ajc

* Added even more nifty JavaScript to cause the hour/minute and end date
  fields of a calendar event form to render as disabled when the "all day
  event" box is checked -- not just when the user checks the box, but also
  when the box begins its life already checked.

Revision 400.49  2002/11/14 04:59:40  ajc
* Correctly serialize and save all day events using date instead of date/time

Revision 400.48  2002/11/13 04:49:23  ajc
* "All day event" shows as a single checkbox, instead of one for the start
  time and one for the end time.  Added nifty JavaScript to zero and shade

  individual items

Revision 400.23  2002/09/24 04:12:34  ajc

* Backed out compression of inlines -- not all browsers appear to handle it

Revision 400.8  2002/09/14 20:20:29  ajc
* Attempting to push more stuff through compression.  I've introduced some
  sort of deadlock bug that I can't seem to find yet...

Revision 400.7  2002/09/14 20:00:22  ajc
* Compress output_image() graphics

Revision 400.6  2002/09/14 16:26:35  ajc
* output_image() now reads the entire image from Citadel into a buffer before

Revision 323.56  2002/08/13 19:55:12  ajc

  the new network architecture of the server.

Revision 301.9  2001/11/18 01:41:09  ajc

* Upgraded all the generic string buffers to 4096 bytes, using the Citadel
  server's convention of #define SIZ 4096

Revision 301.8  2001/11/14 03:20:22  ajc

  and bail out without bothering the Citadel server.

Revision 301.6  2001/08/22 16:38:06  ajc
* Added the "-c" command line option to generate optional cookies indicating
  the host name of the server.  This makes it easy to put a cluster of WebCit
  servers behind (for example) an Arrowpoint load balancer.

Revision 301.5  2001/08/21 04:02:56  ajc
* Added some more meta-tags to (hopefully) prevent the "lame goto" caused by

* A few performance and tuning cleanups.  Increased the size of the socket
  queue length to 100 for use on big systems.  Also, during startup, the
  initial startup thread now exits after creating the worker threads, instead
  of becoming a worker thread itself.  For some reason Solaris had problems
  with the latter method.

Revision 213.22  2001/06/07 03:16:57  ajc
* Brought over an updated mime parser from Citadel

Revision 213.21  2001/06/06 14:44:25  ajc

Revision 213.19  2001/05/30 22:37:09  ajc
* Fix to upload handler to recognize browser uploads based on *either* a "name"
  or a "filename" from the MIME parser.

Revision 213.18  2001/05/30 01:06:57  ajc

* Tagged for the 2.12 release

Revision 211.19  2000/05/18 02:33:39  ajc

  big session logjams when either of these conditions are met

Revision 211.14  2000/04/15 15:43:46  nbryant
* warning fix for 64-bit compile on ultrasparc. (kids don't try this at home,

Revision 1.111  1999/12/03 17:59:53  ajc

          the transition back to the Lobby after it's all done.
        * Added ExpressMessageCat() to allow code to send the user messages
          along with incoming express messages
        * WebCit now sends the name of the end user's browser as the client
          name in a Citadel IDEN command rather than its own name.

          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>

          requests a non-root page and there is no cookie set

          effort, after all)

Sun Apr 18 23:42:54 EDT 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Reworked a lot of the structure, made more HTML "embeddable"

        Changed some output formatting (mainly <FONT> tags).
        Changed who.c to use urlescputs() rather than escputs()
        in urls so GOTOs and User Profiles work when the string has a
        space in it.

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"

Thu Mar 18 00:23:05 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * 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
        * Added "braindamage" file (frames/JS browser compatibility list)
        * Added HTTP "User-agent:" detection
        * wildmat.c, braindamage.c: added
        * Initial value of 'noframes' is now set by the braindamage check
        * Ran everything through "indent -kr -i8"
        * roomops.c: in room list, print a &nbsp; in otherwise empty cells

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>
        * Made the frames stuff less dependent on the HTML TARGET= directive
          and more dependent on the HTTP Window-target: directive.
        * Made the system semi-navigable in noframes mode.

Sat Jan 23 19:36:10 EST 1999 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Brought over the new room listing code and <G>oto heuristics
          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>
        * Reduced the multiple cookies down to one cookie combining all data.

Mon Jan  4 23:04:36 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>
        * Final cvs commit for 1998 (an awful year, I'm glad to see it over).
        * "Finished" the MIME parser.
        * Got image uploads working.
        * Added "add/edit user photo" screens.
        * Added "add/edit room graphic" screens.
        * Added "add/edit floor graphic" screens.
        * Fixed display of floor graphic in known rooms list.

Wed Dec 30 20:36:13 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Wrote mime_parser.c for handling of image uploads.  This will also
          be used in future Citadel MIME projects.

Tue Dec 29 23:25:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Fixed a bug in the room banner display code
        * Added "delete room"
        * Added "validate users"

Mon Dec 28 00:26:01 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Added "edit room info file"
        * Added "edit bio"

Sat Dec 26 23:12:47 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Changed the "auto read new" functionality from a meta refresh tag
          to an "onload" directive (the former was causing graphics problems)
        * Added "create room"
        * Added "edit room"

Tue Dec 22 22:35:50 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Got the Zap and List-Zapped commands working
        * Added a convenience function to display a page with an error string
        * Automatically do a read-new-msgs whenever a new room banner is loaded

Thu Dec 17 20:38:00 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Added the screens to send pages
        * Changed message headers to display in bigger font, non-boldface
        * Added the chat system
        * Added goto private rooms

Wed Dec 16 16:23:58 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Replace "Citadel/UX" in menu bar with the Citadel/UX logo

1998-12-14 Nathan Bryant <bryant@cs.usm.maine.edu>
        * automatically regenerate Makefile when Makefile.in changes

Sun Dec 13 13:35:12 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
        * userlist.c: added.  This adds "userlist" and "show user" functions.
        * roomops.c: fixed buggy implementation of ungoto
        * Set up an option in output_headers() to optionally print the most
          often used opening HTML as well as the HTTP headers.
        * Display express messages in cute little JavaScript popup window.

Fri Dec 11 21:14:36 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Brought over message reading and entry functions from old WebCit

1998-12-10 Nathan Bryant <bryant@cs.usm.maine.edu>
        * context_loop.c: really fix the SO_LINGER stuff
        * webserver.c: remove commented-out references to SO_LINGER

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
          so when the parent process closes it, it actually _does_ close.
          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>
        * context_loop.c, webserver.c, webserver.h: SO_LINGER and locking fix

Wed Dec  9 11:13:48 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Smoothed out some of the login/logout code.  Failed authentication
          now works the way it should.
        * Added support for new user login (still need to handle registration).

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
          displays "Connection reset by peer" error.  It used to work...

1998-12-07 Nathan Bryant <bryant@cs.usm.maine.edu>
        * Makefile.in: updated dependencies

Sun Dec  6 19:50:55 EST 1998 Art Cancro <ajc@uncnsrd.mt-kisco.ny.us>
        * Fixed broken interpretation of variables specified in the URL
        * added new "action" variable to make main loop simpler

1998-12-06 Nathan Bryant <bryant@cs.usm.maine.edu>
        * webserver.c: prototype vsnprintf
        * context_loop.c: warning fix

1998-12-05 Nathan Bryant <bryant@cs.usm.maine.edu>
        * tcp_sockets.c: removed some dead code
        * context_loop.c: oops, I made a memory leak. fix fix fix. also close
          unused ends of pipes, fix a file descriptor leak and a race condition
        * portability enhancements

1998-12-04 Nathan Bryant <bryant@cs.usm.maine.edu>
        * webserver.c, context_loop.c, webcit.c: add commandline args for host
          and port
        * converted to autoconf and began port to Digital UNIX
        * warning fixes
        * context_loop.c: moved the monster 64k buffer array off the stack
        * tcp_sockets.c: getservbyname() doesn't set errno.

1998-12-03 Nathan Bryant <bryant@cs.usm.maine.edu>
        * webserver.c: warning fix
