-2.1, patchlevel 11 -- Sat Jun 5 00:01:01 PDT 1993 -- mann@src.dec.com
-
-* Added code to deal with "wild" games on ICS. This includes allowing
-castling with the king on d1 or d8, which is allowed in wild(1) games
-if the king started there. Notation is o-o to castle "short"---to
-whichever side the king is closer to---and o-o-o to castle "long."
-Right now wild castling is always allowed by xboard; we rely on ICS or
-gnuchess to reject it when we aren't really in wild mode.
-
-* memcpy call had arguments in wrong order.
-
-* Removed April Fool code
-
-2.1, patchlevel 10 -- Mon Feb 15 10:19:31 PST 1993 -- mann@src.dec.com
-
-* Avoid trying to select on a pipe when using System V. Needed to
-copy some code from InitChessProgram() up into establish().
-
-* Bug fix in disambiguating pawn moves like "ed".
-
-* Fix to error handling in ReceiveFromProgram.
-
-* Bug fix: entering EditPosition mode with black to play highlighted
-White's clock instead of Black's.
-
-* Added telnetProgram resource in case "telnet" is not the name of the
-telnet program.
-
-2.1, patchlevel 9 -- Fri Jan 22 19:08:27 PST 1993 -- mann@src.dec.com
-
-* Entering Force Moves mode clears "flag has fallen" messages from display.
-
-* ICS host name can now be in numeric format; for example 128.2.232.4.
-
-* Bug fix: LegalityTest was failing to test whether a pawn move was
-illegal because the move would discover a check.
-
-* Handle ICS message "mann asserts a win over manntest, who disconnected."
-
-* Bug fix: A recent change to PromotionCallBack had broken
-underpromotion to a knight.
-
-* Bug fix: In EditPosition mode, dragging a piece onto a square border
-would make it vanish. xboard wasn't distinguishing this case from
-dragging the piece off the board. Thanks to Matthew Kidd.
-
-* Removed "static" declaration from yywrap for compatibility with IRIX
-version of lex. Thanks to stiller@blaze.cs.jhu.edu.
-
-* Added substitutes for bzero, bcopy, and gethostname for Solaris
-SVR4. Thanks to Michael Grant.
-
-* Bug fixes to queen move disambiguation. Bugs showed up only when
-promotion resulted in more than one queen on the board.
-
-2.1, patchlevel 8 -- Fri Dec 11 17:54:18 PST 1992 -- mann@src.dec.com
-
-* parser bug fix: It now really works to leave off the piece a pawn is
-promoting to and let it default to queen.
-
-* When starting to observe or play an ICS game, don't draw board in
-initial position and then immediately redraw it in the current
-position.
-
-* Handle ICS messages when an "abuser" forfeits a game by
-disconnecting and when a game is aborted ("removed") by an
-administrator.
-
-* Bug fix: A user move when in LoadGame+Pause mode was resuming the
-game load instead of putting us in force mode.
-
-* It seems that crashes inside sscanf when xboard is compiled with gcc
-(as on IBM PS/2 AIX, mentioned below, and also on VAX Ultrix 3.1) are
-caused by an incompatibility between gcc and the sscanf implementation
-on these platforms. A workaround is to specify -fwritable-strings to
-gcc (see the gcc documentation). Added info on how to do this to the
-Imakefile. Thanks to Tom McConnell for this information.
-
-* Clocks are allowed to go negative. This is mostly for ICS
-compatibility, but it affects gnuchess mode too. Also, we give the
-time bonus when a player hits the time control boundary even if his
-flag is already down. This choice is a bit debatable, but it makes
-things look better when you are in TwoMachines mode and gnuchess's
-time management screws up causing it to exceed its time limit.
-
-* Implemented move legality checking code. Moves made with the mouse
-or parsed from a file are checked for legality before being made.
-This is mostly in preparation for future extensions, such as
-human-human play. For now it makes -noChessProgram mode more useful.
-
-* If the user takes back moves, we restore the clocks to the earlier
-settings.
-
-* We now handle the output of the ICS oldmoves command, including
-parsing the game end condition.
-
-* Added autoCallFlag mode.
-
-* Fixed glitches in the medium size outline king and rook bitmaps, and
-touched up the medium size solid king and outline queen.
-
-* bug fix: DisplayMove would not display backwardMostMove - 1.
-
-* Added CallFlag button and removed AcceptMatch. CallFlag is more
-important with new ICS, and accepting the current match offer is easy
-with the new ICS command "accept" (can be abbreviated "ac").
-
-* LoadGame and LoadPosition display tail of file name (plus index
-number, if any) as title.
-
-* MachineWhite, MachineBlack, and TwoMachines now work properly from
-LoadGame and LoadGame+Pause mode.
-
-* Use o-o and o-o-o to castle on ICS, not 00 and 000.
-
-* Stripped out code for old ICS messages; new ICS is now installed.
-
-* Bug fix: don't offer autosave when paused during LoadGame.
-
-2.1, patchlevel 7 - Fri Dec 11 17:40:56 PST 1992 - mann@src.dec.com
-
-* Track change to "Illegal move" message in new ICS.
-
-2.1, patchlevel 6 -- Tue Dec 8 10:48:44 PST 1992 -- mann@src.dec.com
-
-* Kludged around bug in keeping comment popup where you put it by
-adding borderXoffset and borderYoffset resources that give the width
-of the borders added by the window manager. Yucch.
-
-* Changed searchDepth kludge back to using "help" instead of "bd"; the
-latter didn't work because the output contains a line starting with
-"White", so we think gnuchess is telling us that White won. Oops.
-
-* Removed some code that uses an X11R5 feature, XrmGetDatabase.
-Without this, the auto font sizing code is harder to make work, so to
-keep my sanity I had to change it to affect only the fonts that appear
-in the main window and the comment popup, not the other popups. Maybe
-this is better anyway.
-
-* AcceptMatch button now works after a counterchallenge, too.
-
-* Added code for more variants of messages about games being adjourned
-or aborted. These messages need to be unified in new version of ICS.
-
-* Added workaround for minor bug in ICS; game number on first board
-can be wrong.
-
-* Removed code to say "refresh n" instead of "refresh"; was broken and
-wasn't needed anyway.
-
-* Added missing casts for compilers that distinguish enums from ints
-and missing cast in connect call.
-
-* Added code to recognize "both sides are out of time" draw message
-proposed for next version of ICS.
-
-* Thanks to Danny Sleator and Joe Peterson for bug reports.
-
-2.1, patchlevel 5 -- Sun Dec 6 19:52:40 PST 1992 -- mann@src.dec.com
-
-* Removed gcc and CDEBUGFLAGS from Imakefile.
-
-* Corrected setting of mode to ForceMoves when game file ends or
-contains an AmbiguousMove or BadMove. Previous bug was harmless.
-
-* Added AcceptMatch button and mention of 50-move rule for Draw button
-to man page.
-
-2.1, patchlevel 4 -- Sun Dec 6 02:55:42 PST 1992 -- mann@src.dec.com
-
-* Now handles revised messages from new version of ICS. New ICS is
-not released yet, so this code might change further. Next patchlevel
-will remove support for old ICS; both are there now.
-
-* Initial processing for a new game being watched or played now
-happens when we see the first board image. Removes the need to parse
-some messages and unifies some code.
-
-2.1, patchlevel 3 -- Tue Dec 1 19:40:40 PST 1992 -- mann@src.dec.com
-
-* Handles ICS messages "Draw : neither player has mating
-material" and "Draw : White has no material, Black has no time."
-
-* Added AcceptMatch button for ICS mode.
-
-* Fixed bug in previous fix to yylexstr().
-
-* Fixed bugs in code for loading old position files that don't start
-with "#" and for handling case where user asked for nth position in
-file but there aren't that many.
-
-* Handles ICS message "* has restored your old game"
-
-* ResetProc always clears title line now.
-
-* Don't issue just "refresh" when watching a game; use game number.
-Upcoming new version of ICS may need this.
-
-* Added code to try to prevent user from watching and/or playing more
-than one game at a time. There is a race condition inherent here; if
-we get more than one board from the game before our command to stop
-watching it takes effect, we'll think the user started it again. Not
-clear how to fix this.
-
-* Redid ParseBoard8 to use sscanf. Code is a good deal cleaner now.
-Also, we now parse out the game number too, though we don't make much
-use of it yet.
-
-* (Tried to put in a feature that recognizes the current game in a
-game file must have ended when we see the start of a new one, but had
-to disable it because we have too many false hits with the current
-parser, especially in gnuchess listing files.)
-
-* Moves read from game files or received from ICS are now translated
-into canonical algebraic form just like all other moves. Minor nit:
-If you use Reset while playing or observing a game in ICS mode, the
-game history (including the current board position) is lost, so the
-next move of the current game can't be translated.
-
-* Default fonts now vary with board size, and are chosen by pixel size
-instead of point size (since piece bitmaps have a fixed pixel size).
-
-* Bug fix: An extra Forward was required to skip over time indications
-in game files.
-
-2.1 patchlevel 2 -- Fri Nov 27 23:30:00 PST 1992 -- mann@src.dec.com
-
-* If you move the comment popup, the next time it pops up it will come
-back where you put it.
-
-* Fixed yylexstr() so calls to it can be interspersed with calls to
-yylex().
-
-* Fixed bugs in Forward/Backward while in LoadGame mode.
-
-* Changed Save{Game,Position} functions to append instead of
-overwriting if file exists. Changed Load{Game,Position} functions to
-deal with multiple games/positions per file.
-
-* Changed load{Game,Position}File resources to trigger automatic load
-on program startup. Changed save{Game,Position}File resources to
-trigger automatic save after every completed game and on program exit.
-
-* Added autoSaveGames mode.
-
-* Fixed bug with PromoPiece in call to MakeAlg from MakeMove.
-
-* Many changes to get rid of picky compiler warnings and generally
-clean up the code.
-
-2.1 patchlevel 1 -- Fri Nov 27 02:45:00 PST 1992 -- mann@src.dec.com
-
-* A last minute change before patchlevel 0 went out broke
-ParseGameHistory(). Immediately fixed in patchlevel 1.
-
-Version 2.1, patchlevel 0 -- Fri Nov 27 02:00:00 PST 1992 -- mann@src.dec.com
-
-* Uses "time" command of gnuchess 4.0 and following to keep clocks in
-sync. Still works with older versions without this command; we test
-whether the command is present the first time each chess program is
-started.
-
-* File name dialog pops up under the mouse cursor, so that it's got the
-keyboard focus if the window manager is using pointer focus.
-
-* Attempts to move the wrong color piece or an empty square are filtered
-out in xboard instead of being passed on to GNU Chess or the ICS.
-
-* The reason a game ended is now remembered even if you move backward
-and forward after it ends. It is forgotten only if you make a move
-(which is as it should be---this is now a different game, which hasn't
-ended yet). The message saying why the game ended no longer wipes out
-the last move.
-
-* Pause, Backward, Forward, ForceMoves, and EditPosition now work from
-TwoMachines mode.
-
-* Forward and Backward now change only the board display unless you
-are in ForceMoves mode. Pause mode keeps new moves that are received
-from being displayed on your screen until you unpause (or use
-Forward).
-
-* Added option to ring the bell after opponents' moves.
-
-* Saved games that start from other than the standard initial position
-now begin with a postion diagram as in saved position files. The
-loader is modified to understand such save files.
-
-* Improved error checking when trying to read from gnuchess.
-
-* Parser understands things that look like time indications, e.g., (0:12),
-instead of popping them up as comments.
-
-* Send "quit" to gnuchess before trying to kill it. I needed this
-locally because sending a SIGTERM to rsh was not killing the remote
-program on some internal field test systems we have.
-
-* Merged in code from John Chanak to make xboard a front end to the
-Internet Chess Server, and added several improvements of my own.
-(These include parsing end of game messages, loading the current state
-and previous history of a game that's joined in progress via "watch"
-or "load", automatic switch from board style 1 to 8 when needed,
-removing irrelevant buttons and adding some new ones, adding the
-useTelnet and gateway resources, and miscellaneous code cleanup, bug
-fixes, and documentation.) Many thanks to John for writing and
-contributing the initial version of this code.
-
-Fri Oct 30 20:16:40 PST 1992 (patchlevel 25) mann@src.dec.com
-
-* gnuchess now castles by sending us "o-o" or "o-o-o" (starting with a
-preliminary version of 4.0.pl60 that I have). Added code to handle
-this. The old format ("e1g1", etc.) still works too.
-
-* Added code to format moves in normal abbreviated algebraic notation
-(for example, e4, exd4, f8Q, Nf6, 0-0) instead of coordinate algebraic
-(for example, e2e4, e3d4, f7f8q, g1f6, e1g1). Moves entered with the
-mouse or received from gnuchess are translated into this canonical
-format for display on the message line or in saved game files. Moves
-read from game files are not translated, however; they are shown and
-saved just as they appear in the file.
-
-Mon Sep 14 13:19:01 PDT 1992 (patchlevel 24) mann@src.dec.com
-
-* It's not really correct to write an ep capture of a pawn on e5 as
-fxe5; this should be written as fxe6 because e6 is where the capturing
-pawn ends up. Nevertheless, the parser now interprets fxe5 as the ep
-capture f5xe6 unless there is a pawn on f4, in which case it
-interprets fxe5 as f4xe5. By design, the parser does not flag fxe5 as
-ambiguous if there are pawns on both f4 and f5; instead it prefers the
-more legitimate f4xe5 interpretation.
-
-* A move like fxe6 or fe6 is now interpreted as an e.p. capture of the
-pawn on e5 if there is one there and e6 is empty.
-
-* A move like fxe5 can no longer be interpreted as an e.p. capture if
-there isn't a pawn on e5 to be captured. Previously this could happen
-erroneously if there were pawns on both f4 and f5, and the f4 pawn was
-capturing a piece on e5.
-
-* The parser no longer munges the move it is parsing; in the past, for
-instance, it would remove the "x" from a move like dxc5 before echoing
-it to the screen.
-
-* The parser now detects when a move is ambiguous and returns an
-error, instead of arbitrarily choosing one possibility as it used to.
-
-Mon Aug 10 18:40:47 PDT 1992 (patchlevel 23) mann@src.dec.com
-
-* Added code so parser can handle fully qualified algebraic, e.g.,
-Ng1-f3, N/g1-f3, Ng1f3, or even Pe2-e4. The "P" and "/" work only for
-fully qualified moves, not generally.
-
-* Fixed parser bugs in handling moves with rank or file disambiguator,
-e.g. N1f3 or Ngf3.
-
-Mon Jul 6 17:55:32 PDT 1992 (patchlevel 22) mann@src.dec.com
-
-* AIXV3 patch from Tom McConnell; thanks!
-
-* After hitting the Backward button we see the last move made instead of
-the word "Pausing" displayed.
-
-* Fixed a couple of problems compiling on IRIX; thanks to Michel Arsenault
-and Alan Walsh for bug reports and help with fixes.
-
-* Added optional display of algebraic notation coordinates along left and
-bottom edges of board. This was inspired by some code from Jean-Christophe
-Engel; thanks!
-
-* Swapped EditPosition and Pause buttons to reduce danger of losing the
-game in progress by hitting EditPosition when you wanted Backward. Thanks
-to Ove Lundberg for complaining (though it bugged me too).
-
-* Despite one complaint, I kept the feature of changing both clocks when black
-makes time control, rather than changing each individually when the player
-involved makes it. This is to avoid having it look like White is way ahead on
-time while Black is thinking about the last move of the time control period
-(i.e., when White has made time control but Black hasn't yet).
-
-* Corrected clocks to work as in real tournaments. Time is *added* when you
-reach time control; previously the clocks were simply set to the length of the
-new time period. Also, when a player's flag falls, he still does not receive a
-new time allotment at the next time control, but his opponent does still
-receive more time if *his* flag has not fallen; previously, time controls were
-ignored for both players if either flag fell. I forget who reported this bug.
-
-* Added a small ESIX patch from Kayvan Sylvan.
-
-Mon Jun 22 13:24:38 PDT 1992 (patchlevel 21)
-
-* Added some SVR4 support code from Ronald Cole. It's Greek to me.
-
-* Note: Stephen Meatheringham reports a bug causing xboard to crash with an
-error from the X server when run on a Sun Sparcstation IPX with Solaris 1.0.1
-and OpenWindows 3.0. This bug has not been tracked down yet.
-
-* Fixed a problem with ATTENTION code. On some operating systems, you have to
-be even more cautious about when you send a SIGINT to gnuchess, because the
-signal handler gets deinstalled each time it is used, and gnuchess does not
-reinstall it immediately. In particular, if you send a SIGINT and make an
-illegal move or ask for a hint, gnuchess does not reinstall the handler until
-*after* you make your next move, so you had better not send a SIGINT before
-it. I put a workaround for this case into xboard; I hope there are no more.
-
-* The ATTENTION code is needed when compiling for the ESIX operating system,
-because ESIX has a bug in the FIONREAD ioctl, so the code in gnuchess that
-lets you interrupt its thinking on your time just by typing in your move does
-not work. Perhaps gnuchess will have a workaround for this eventually.
-
-* Fixed yet another bug in using XtGetValues; code to inhibit shell resizing
-was leaving a null pointer as the place to store the current sizes.
-
-* Man page fixes: corrected -sl to -sd, updated LIMITATIONS.
-
-* Added include of <sys/time.h> conditional on HAS_GETTIMEOFDAY. I hope this
-works for all systems; on mine, <time.h> and <sys/time.h> are the same file,
-but with an #ifndef that makes it harmless to include both.
-
-* Thanks for reports from Mike Pearlman, Stephen Meatheringham, Kayvan Sylvan,
-d87-mal@nada.kth.se, Urban Koistinen, and Ronald Cole.
-
-Mon Jun 8 11:39:18 PDT 1992 (patchlevel 20)
-
-* Documented default value of initString and explained what it means. This
-paragraph also serves to inform the user that xboard by default will tell
-gnuchess to think on his time, something one user apparently didn't understand.
-
-* Redid -searchDepth (formerly -searchLevel) and -searchTime code. They both
-work correctly with gnuchess 3.1 now. The -searchDepth option also works
-correctly with gnuchess 4.0. The -searchTime option does not work with
-gnuchess 4.0.pl50 or earlier because those gnuchess versions do not have a
-working searchTime feature. Instead of having xboard do a half-baked emulation
-of this feature by using a 1-move time control, I will be submitting a patch to
-the gnuchess folks to restore the feature as in 3.1.
-
-* Improved clock code. It now keeps accurate track of fractional seconds of
-clock running time, if your system has gettimeofday(); if not, it is generous
-about them---if a clock has been going for n.m seconds when it is stopped, only
-n seconds are charged. Previously, xboard would charge one second immediately
-when a clock was started, so if n.m had elapsed when it was stopped, n+1 would
-be charged. This should stop xboard from thinking gnuchess has let its flag
-fall on the last move of a time control, as it often did before. I also
-improved the comments and condensed the code a little. I hope there are no
-systems that have X11 and don't have gettimeofday(), but if there are, I'd like
-to know what to replace it with.
-
-* "Flag dropped" messages now show up on the top line, beside the clocks, so
-that they don't obscure more interesting messages on the second line.
-
-* Fixed confusion of NULL and '\000'.
-
-* Include time.h to get ctime() declaration.
-
-* Fix to "parser bug" messages in parser.l.
-
-* Changed code to work with old-fashioned tolower() macro that requires its
-argument to be an uppercase letter.
-
-* Minor fix to some usage error messages; was reversing program name and
-erroneous argument value.
-
-* Thanks to Mitch Wright, Ranier Orth, and Henrik Schmiediche for bug reports.
-
-Fri Jun 5 13:06:08 PDT 1992 (patchlevel 19)
-
-* Note: xboard does not seem to work when compiled with gcc 1.40 on a
-PS/2 running AIX. It crashes at the sscanf in line 768 of xboard.c.
-You can work around the problem by specifying the -timeControl option
-on the command line instead of defaulting it. This does not seem to
-be a bug in xboard itself; it runs okay on PS/2 AIX when compiled with
-MetaWare High C. [But see 2.1.pl8 above.]
-
-* Removed bogus files from distribution.
-
-* Changed variable name that conflicted with SVR4 ttyname function.
-
-* Thanks to Christoph Strozyk for another bug report, and to several
-of the folks mentioned under patchlevel 18 for testing it.
-
-Wed Jun 3 17:50:37 PDT 1992 (patchlevel 18) mann@src.dec.com
-
-* Added an include of sys/fcntl.h to pick up the definition of O_RDWR for
-System V users.
-
-* Fixed a bug in CatchPipeSignal; was testing the wrong variable to determine
-which chess program got the signal.
-
-* Removed the declaration of strrchr, which was causing problems for some
-people, and added an include of <string.h> or <strings.h> instead.
-
-* Fixed a bunch of type errors uncovered by compilers that check more carefully
-than the one I was using. I just patched many of them with casts---typically
-cases where a function didn't take the same number and type of arguments as the
-X header file prototype said it should---because I didn't see any other way to
-fix them. The versions of the X header files that I have don't actually have
-full prototypes for these function types; they declare only the return type and
-just give the argument types as comments.
-
-* InitChessProgram returns immediately if chess program died while we were
-waiting for it to say "Chess". I think this fixes a bug that could make xboard
-crash or go into an infinite loop printing "Warning: Select failed; error code
-9" if gnuchess crashed there.
-
-* Removed code that tries to put the file descriptor used to read messages from
-gnuchess into nonblocking mode. I don't see how this kludge could ever have
-fixed the problem it was intended to (see below), and it seemed to be causing
-a race condition when we were waiting for the initial message from gnuchess
-after it started up.
-
-* Thanks to Richard K. Lloyd, Konstantinos Konstantinides, Mark
-Seiden, Erik Schoenfelder, Andreas Stolcke, Rainer Orth, Henry Thomas,
-and Kris Van Hees for bug reports and help with fixes.
-
-Sun May 31 08:00:00 PDT 1992 (patchlevel 17) Bart Massey bart@cs.uoregon.edu
-
-* 'xboard' suffered from a couple of serious bugs. An initial
- size needed to be given to the message label to avoid a race
- condition (!) so I gave it some text (otherwise occasionally
- xboard would fail because the message widget was 0 width under
- MIT X11R4). The sizes needed to be Dimension, not int, because
- they were written in by Xt -- on my big-endian box Dimension
- is short, causing chaos. Also, I hacked a declaration in for
- strrchr() to shut the compiler up -- this is arguably a kludge,
- but I couldn't think of anything better; maybe you can.
-
-Fri May 22 13:40:50 PDT 1992 (patchlevel 16)
-
-* First real (non-beta) release of version 2.0.
-
-* Added GNU copyleft notices covering version 2.0 enhancements.
-
-Thu May 21 12:30:09 PDT 1992 (patchlevel 15)
-
-* Removed -g from Imakefile.
-
-* Added casts in parser.l to prevent warning messages from some C compilers.
-
-* Bugfix: code to exit if chess program couldn't be started had bug in error
-message printing.
-
-Tue May 19 11:58:06 PDT 1992 (patchlevel 14)
-
-* Fixes one small bug: If LoadGame does not find a game in the file, it resets
-xboard to BeginningOfGame mode (as if the Reset button was pressed), instead of
-leaving it in LoadGame mode.
-
-Mon Apr 13 18:32:27 PDT 1992 (patchlevel 13)
-
-* Improved error handling when gnuchessx crashes. Now displays a message and
-enters EndOfGame state without exiting. This should help with diagnosing
-gnuchessx problems, since the position and move history are not lost.
-
-* Debugged man page.
-
-Version 2.0 -- Thu Apr 2 16:04:54 PST 1992 (patchlevel 12)
-
-* Added small 40x40 pixel pieces; board size now specified as small, medium, or
-large.
-
-* Improved man page.
-
-* Saved position files now say "white to play" if it's white's move.
-
-* SavePosition while in EditPosition mode now gets side to play right.
-
-* Made "Pawn" the default on edit position menus.
-
-* Removed "To play" from edit position menus, since it's redundant. Left
-support code in so it can be restored if someone wants it.
-
-* Tightened parser's definition of a move number to help further with skipping
-over stuff before the first move.
-
-* Put back feature of skipping over stuff in game files before a start of game
-marker. This helps when loading electronic mail messages that have things
-like "00" in the header (looks like castling), or that talk about moves in
-running text before the actual game score. Tradeoff is that we can't load
-games that don't either have move numbers or say "gnuchess game" just before
-the moves.
-
-* Changed version number to 2.0 because others have used "1.3" for patched
-versions of 1.2. Display version number and patchlevel at startup.
-
-Thu Apr 2 15:30:22 PST 1992 (patchlevel 11)
-
-* Bugfix: Match started with TwoMachines button now handles the case where
-user loaded/edited a position *and* forced some moves.
-
-* added error message feedback to many cases where the user's button press is
-rejected because it isn't allowed in the current mode.
-
-* added -noChessProgram option to allow use as a passive chessboard without
-gnuchess, replacing old buggy scheme that tried to do this automatically when
-gnuchess was not found on the search path.
-
-* parser accepts "=" in front of promotion piece
-
-* parser accepts ":" notation for captures
-
-* Removed SwitchSides button to make room for EditPosition. Left code in
-place, ifdef'ed out.
-
-* Added EditPosition mode.
-
-* Reformatted xboard.c to eliminate long lines.
-
-* Promotion popup now appears near rank to which pawn is moving.
-
-* UI improvement: Button representing current program mode is kept highlighted.
-
-* Bug fix: Hint button is now disabled when machine is on move.
-
-Sat Mar 21 14:57:37 PST 1992 (patchlevel 10)
-
-* TwoMachines now works from MachineWhite or MachineBlack mode.
-
-* ForceMoves and Backward/Forward now work at the end of a game started by
-the TwoMachines button.
-
-* Sends o-o or o-o-o to gnuchess instead of O-O or O-O-O.
-
-* Bug fix: SwitchSides button is now disabled when machine is on move.
-
-* Added -searchLevel option and corrected handling of -searchTime to reflect
-the way gnuchess really handles command line options instead of what the
-documentation used to say. Allowed optional ":seconds" on times.
-
-Tue Mar 17 21:00:35 PST 1992 (patchlevel 9)
-
-* Removed non-working code that tried to recover when a remote chess program
-could not be started; now exits with a message instead.
-
-* Now waits for chess program to print its first message (normally "Chess")
-before sending it any commands.
-
-* Matches between two machines can now start from a black-to-play position or
-black-to-play opening.
-
-* Bug fix: The program would sometimes lose track of the board position after
-the end of the game, drawing a board full of white pawns next time it got an X
-redraw request. Now fixed.
-
-* Cleaned up handling of illegal moves in game files. Now we just stop reading
-and go into ForceMoves mode.
-
-* Saved games against gnuchess indicate who won (restored and debugged 1.2
-feature).
-
-* Setting -searchTime turns off -clockMode.
-
-* My trick for setting up a black-to-play position broke in the transition from
-gnuchess 3.1+ to 4.0. Installed a different trick that works with both.
-
-* Bug fix: Was clobbering memory by mallocing one byte too few for the file
-name in SetupPositionFromFileProc. This usually resulted in a crash on the
-second attempt to load a position from a file.
-
-Mon Mar 16 16:49:00 PST 1992 (patchlevel 8)
-
-* Game and position files are saved in CHESSDIR as well as loaded from there.
-We actually chdir there, so gnuchess listing files also wind up there.
-
-* Underpromotion moves from gnuchess really work now.
-
-Sat Mar 14 14:55:24 PST 1992 (patchlevel 7)
-
-* Cleaned up lots of bugs and kruft in parser.l. It's a wonder the old version
-worked at all. Improved rejection of random text interspersed with the moves.
-
-* Relabeled buttons to reduce confusion (Play From File --> Load Game;
-Setup From File --> Load Position).
-
-* Bug fix: Doesn't exit at the end of a game that was started by pressing
-the Two Machines button.
-
-* Bug fix: Doesn't get confused if you hit Machine Black (White) while
-the machine is already playing black (white) and is on move.
-
-* Prints "White to play" or "Black to play" after loading a position file.
-
-* Bug fix: No longer hangs if no start-of-game is found in a game file.
-
-* More permissive about game file format. The first line is not assumed
-to be a header comment unless it starts with "#". We don't insist on
-seeing a "1." before the first move.
-
-* Added pop-up dialog to allow underpromotion. Moving a pawn to the last rank
-pops up a dialog to let you select what piece to promote to. Also added code
-to handle underpromotion moves from gnuchess or from a game file correctly.
-
-* Added code to send SIGINT to gnuchess before trying to move, if gnuchess
-might be busy thinking on our time. The code is ifdef'ed out because it's
-not necessary; only beta-test versions of gnuchess 4.0 at patchlevel 19 or
-below require it.
-
-Mon Feb 24 20:10:22 PST 1992
-
-* Merged fixes received from Stuart Cracraft and Mike McGann, to iconic mode
-and to ShutdownChessPrograms. (They both sent the same fixes.) I did not
-install the change that removed "easy" from the initialization string, so
-xboard will still try to run gnuchessx in "hard" mode (thinking on opponent's
-time) by sending this command.
-
-Version 1.3 -- Thu Dec 19 18:19:00 PST 1991 mann@src.dec.com (Tim Mann)
-
-* I've fixed a slew of bugs in this version of xboard:
-
-* You can now back up from the end of a game, even if gnuchess was playing
-against you. Since gnuchess exits upon mate or draw (when it's not in force
-mode), this feature works by starting up a new copy of gnuchess and feeding it
-the saved starting position and moves. Drawback: the new gnuchess starts with
-clocks at the beginning of a fresh time control.
-
-* Note: the "force" command to gnuchess is a toggle. I fixed a couple of
-places in xboard where "force" was being issued when gnuchess was already in
-force mode, which resulted in chaos. I don't know if they were in 1.2 or if I
-added them myself in the course of putting in new features.
-
-* ForceMoves button is now legal in PlayFromFile mode. It closes the game file
-and lets you force moves (or go Backward) from whatever position you've
-reached.
-
-* The parser now recognizes "white resigns" and "black resigns" (in any
-combination of upper and lower case, with or without the closing "s"). These
-used to be misinterpreted as meaning "white wins" or "black wins" respectively!
-Added "1 - 0" and "0 - 1" as equivalents for "1-0" and "0-1".
-
-* I removed the parser feature of considering "!" as a comment delimiter.
-"!" is so common as an annotation in game scores that this feature seems like a
-very bad idea.
-
-* Added a wait() after each successful call to kill() to avoid leaving zombie
-processes around.
-
-* Removed the feature of putting an indication of how the game ended into the
-internal move list when playing from a file. The only benefit of this was that
-it would get written back out if you saved the game at that point. This
-feature doesn't seem too useful, since you are unlikely to save a game you've
-read in without making any changes, and it caused a lot of problems in the code
-and user interface. The end condition is still displayed as a message when
-it's first read in from the file. End conditions when playing against gnuchess
-are still saved, too.
-
-* programName is now the last file name component of argv[0], not all of it.
-
-* xboard.c got three compiler warnings due to arguments that didn't match the
-prototypes on X toolkit functions. I got rid of them by adding some casts, and
-adding extra unused arguments to the ReceiveFromProgram function.
-
-* As I received it, the distribution had an extra period glued on the front
-of every line that started with a period. This broke the manpage in an
-obvious way. It also broke parser.l in a nonobvious way that stopped
-PlayFromFile from working.
-
-* Fixed one or two bugs where the clock was started when it shouldn't have
-been. I think one example was if you tried an illegal move in ForceMoves mode.
-
-* Now starts the machine's clock if you hit MachineWhite when white is on move
-or MachineBlack when black is on move.
-
-* Now updates the to-move indicator (highlight on clock display) when you use
-Forward/Backward or ForceMoves.
-
-* gnuchess 3.1+ has a bug that makes it try to think on its opponent's time
-even when in force mode; this causes problems with xboard's SetupFromFile
-command because gnuchess's saved hint move is garbage after the new position is
-loaded, so gnuchess prints out an error message when it tries to think about
-what it would do if the user made this move. Here is a patch for gnuchess
-3.1+:
-
-*** nondsp.c~ Mon Dec 2 12:37:18 1991
-*-- nondsp.c Thu Dec 19 15:36:06 1991
-***************
-*** 1223,1229 ****
- ok = flag.quit = false;
- player = opponent;
- ft = 0;
-! if (hint > 0 && !flag.easy && Book == NULL)
- {
- fflush (stdout);
- time0 = time ((long *) 0);
-*-- 1223,1229 ----
- ok = flag.quit = false;
- player = opponent;
- ft = 0;
-! if (hint > 0 && !flag.easy && Book == NULL && !flag.force)
- {
- fflush (stdout);
- time0 = time ((long *) 0);
-
-* SavePosition/SetupFromFile now handle black-to-play positions. If it's
-black's move in a saved position, the line "black to play" is printed
-immediately after the board display. Upon loading a position, xboard
-looks for "black" at the beginning of this line to determine whether it's
-black's move.
-
-* SetupFromFile now leaves you (effectively) in ForceMoves mode. This
-eliminates some cases where the program would get into an inconsistent state,
-and hopefully is more intuitive for the user, too.
-
-* PlayFromFile now leaves xboard in ForceMoves mode after playing through all
-the moves in the file. You can use Backward/Forward, make moves, get gnuchess
-to join the game with MachineWhite or MachineBlack, etc. The game file can end
-with either white or black to play.
-
-* Backward/Forward now seem to work in all cases. Previously using these
-buttons during a game against the machine would get xboard out of sync with
-gnuchess's idea of what was going on, resulting in chaos. Now using these
-buttons puts xboard in ForceMoves mode; you can bring gnuchess back into the
-game using the MachineWhite or MachineBlack buttons.
-
-Thu Jun 27 15:06:25 PDT 1991
-
- * Remove comment popups during a reset.
-
- * Bug in my forward move fix. Didn't work for playgamefile mode.
-
-Thu Jun 20 15:04:06 PDT 1991
-
- * Can't do a backward move when it isn't your turn because gnuchess
- gets confused. Similar bug for forward move. Do a bunch of moves,
- back up move and go forward. These get filtered out now.
-
- * Put easy back into the initString. This DISABLES easy mode which by
- default is ON.
-
- * New-line wasn't always being added to forward move strings sent to gnuchess.
-
- * Parsed comments as [ ..............text follows ] into d7d5
-
- * Long game file comments cause core dumps on HP systems.
-
- * Multiple uses of the get positition file button got confused
- on the second click.
-
- Minor fixes to the 1.2 release
-
-Version 1.2 -- Tue Jun 11 17:14:12 PDT 1991
-
- * For version 1.2, Jeff Kenton, Richard LLoyd, David Jensen, Martin D.,
- Bill Schmidt, Scott Hemphill, Paul Vaughan and Bill Shauck all found
- a lot of bugs that we put into xboard just to see if they were paying
- attention. They were.
-
- * Changed the protocol that xboard uses to work with the new version of
- gnuchessr.
-
- * There was an off by one error with the clock resetting code. Also,
- the clock display highliting was wrong. Thanks to Bill Shauck for
- pointing these out.
-
- * enumerations are not really integers on some C compilers. I added casting.
- The new version of gnuchess expects the "go" command for two machine
- and machine plays white cases. The whiteString resource is for
- compatibility with previous gnuchess versions which get confused by go.
- Thanks to Martin D. for catching these.
-
- * Fixed a bug where the checkmate message wasn't being parsed and xboard
- kept playing. Also, the message was added to game file if saved.
- Thanks to Scott Hemhill for pointing this out.
-
- * Fixed a bug where saving a long game, resetting and saving a short game
- resulted in appending the end of the long game to the short one.
- If a game is just being played out and there is no reason for gnuchessr
- to be used, ignore pipe signals. This allows people to use xboard
- as a chess board without need for gnuchess. Also, trivially bad moves
- such as e2e2 are not passed on to gnuchessr but instead ignored out of
- hand. This allows people using xboard as a chessboard with gnuchessr
- to pick a piece up, think and put it back down without making a move.
- Thanks to Jeff Kenton for pointing these out.
-
- * Added the CHESSDIR environment variable. Game and position files are
- found in this directory. If this variable is not declared, then the
- current directory is used. File names starting with / are treated
- specially.
-
- * The bitmap file names were changed so that none exceeded 14 characters.
- This is necessary for R5.
-
- fcntl(from_prog[0], F_SETFL, O_NDELAY);
-
- The xboard fix was to set non-blocking i/o on the read pipe for gnuchessr
-
- printz ("Illegal move (no matching move generated)");
-
- * fixed a problem with the new version of gnuchessr where xboard wasn't
- getting gnuchessr error messages for illegal moves. The problem seems
- to be fixed *without* any gnuchess changes but this is likely to be
- highly system dependant. There should be a new line on line 246 of nondsp.c
-
- * -iconic doesn't work at all now. The Iconify() does work. This was
- a tradeoff and it is really an Xt bug.
-
- * Fixed a compiler warning for gcc and an error for the IBM RT compilers.
- This is the VOID_PROC macro in xboard.h. Thanks to David Jensen for this.
-
- * If the DisplayWidth or DisplayHeight is less than 800, use small size mode.
- Also the size of the name widget was reduced from 500 pixels to 400 pixels
- because in small size mode there was a gap on the right.
- Changed the default font from fixed to helvetica_oblique14 to:
- **-helvetica-bold-r-normal--14-*-*-*-*-*-*-*
- helvetica_oblique14 is a font alias not on all R4 systems.
- Curiously enough, the 17 point is not available on 75dpi systems
- and the 18 point font is not available on 100dpi systems.
- Thanks to Richard K. Lloyd for pointing these out.
-
- * Minor hacks to work with R5 alpha. Had to add an event handler to the
- boardWidget to get translations to work. This may go away with the real R5.
- Added <Message>WM_PROTOCOLS: QuitProc() for R5 ICCCM compatibility.
-
- * If the first character of the file is not `1' then the first line
- of a game or position file is displayed as the name in a label widget.
-
- * Added a PopUp dialog for getting file names.
-
- * Modified the code to use the R4 routines rather than R3 compatibility.
-
- * Changed the forwards/backwards/readgamefile code to allow a play to step
- back and forth in a game. If he steps all the way to the beginning
- he has to restart the game. If he gets into a mated position, same problem.
-
- * Moved the man page from xboard.1 to xboard.man. This makes imake man page
- installs work correctly. Thanks to Richard K. Lloyd for pointing this out.
-
- * Corrected the queening code. XBoard was sending the wrong syntax.
- It was sending for example h8(Q) when it should have been sending h8q.
- Thanks to Paul Vaughan and Mike McGann for pointing this out.
-
- * Added a lex parser for algebraic games. It should be easy to use the parser
- for other interfaces such as the Microsoft Windows version.
- It parses comments of the form [anything] and ! to the end of a line.
-
-Version 1.1 -- Mon Jan 7 14:46:03 PST 1991
-
- * Roger Dubar, Konstantinos Konstantinides, Wolfgang S. Rupprecht,
- Paul Scowen, Mvh Smidt and Kayvan Sylvan all helped immensely during
- beta-testing.
-
- * older non-ANSI versions of Sun compilers complain vociferously.
-
- * the remoteShell resource was added for HP-UX systems
- and other systems where the remoteShell isn't rsh.
-
- * -iconic doesn't work properly. If XBoard is opened iconic then
- iconifying it later with a keystroke doesn't work. I think
- this is an Xt bug.
-
- * For systems with smaller screens, XBoard can use smaller pieces,
- and a smaller board. -bigSizeMode False uses a smaller set of pieces.
- These are scaled versions of the large pieces. They look ok but could
- be improved.
-
- * getlogin() does not work in all cases.
- It was replaced by getpwuid(getuid())->pw_name).
-
- * Warning messages get displayed in the message box.
-
- * Any button restarts a paused game.
-
- * Kayvan Sylvan contributed a patch for ESIX.
- It seems that select() on pipes is broken on his system. We declined
- to incorporate his patch though, because it was a work-around for
- something that was broken on one system, and selfishly, that system
- was not my own. Nevertheless, it is likely that other System V users
- on PC's may need to use this patch and it is is included as the file
- ESIX.patch. To use it, type
-
- patch xboard.c ESIX.patch
-
- * Fixed a bug where hint didn't work. The local version of gnuchessr
- had been hacked. The fix was to clone stderr and stdout for gnuchessr.
-
- * Fixed a bug where a player could play after a game had been finished.
-
- * The bitmaps have been pushed into the bitmaps directory.
-
- * Substantially rewrote and simplified the Two Machine code.
-
- * Added StrStr() because many systems don't have this ANSI function.
-
- * Added keyboard equivalents. Added an iconify keystroke, C or c.
-
- * Works with gcc now. gcc complained about casting float constants
- as XtPointers.
-
- * Detect if the visual doesn't support color. If so, run in monoMode.
- An alternative would be to detect grayscale visual and use a collection
- of gray user interface colors.
-
- XBoard.clockMode: False
-
- * For people who don't like or use chess clocks a clockMode switch
- has been added. It is on by default. It can be turned off in the
- .Xdefaults file with
-
- * Added a declaration, xtVersion, which will quickly break on R3 Intrinsics.
-
- * Hal Peterson contributed a new Imakefile.
-
- * Rewrote DisplayClocks().
-
- * Rewrote TwoMachinesPlay mode.
-
- * Konstantinos Konstantinides added the -searchTime option.
-
- * Substantially rewrote and simplified the clock code. If a game was paused
- and then resumed, the clocks were out of sync.
-
- * Fixed a bug in HandleUserMove() where the user could make a move while the
- machine was thinking. The fix detects and ignores these moves. onMove
- was not being used and was removed.
