[shogi-server] Create a directory for a PID file. (Closes #38546)

[shogi-server/shogi-server.git] / changelog

2018-08-25  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] Support a graceful shutdown.
          A file named "STOP" in the base directory prevents the server from
          starting new games including Floodgate matches.
          (Closes #38544)
        * [shogi-server] Create a directory for a PID file.
          To put a PID file such as /var/run/shogi-server/shogi-server.pid, if
          directories do not exist, they will be created recursively.
          (Closes #38546)

2018-04-07  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] Give more penalty on assigning matches with same
          players.
          (Closes #38178)

2017-09-03  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] Write game results in categorical files
          The shogi-server now writes down game results in the following
          files, depending on a game class:
          - 00LIST: all games
          - 00LIST.floodgate: floodgate games
          - 00LIST.others: non-floodgate games
          (Closes  #37492)

2017-09-02  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] Write more game results in record files
          As the CSA Record Format standard states, "%TIME_UP" and
          "%SENNICHITE" are now recorded in CSA files when a game ends for
          timed up or sennichite respectively.
          (Closes #37490)
        * [shogi-server, mk_game_results, mk_rate] Change schema to add number of
          moves The format of an internal game result summary file, '00LIST',
          has been changed to add number of moves of a game, which would be of
          help for a script calculating rating scores.
          (Closes #37491)
        * Update Revision to 20170902

2017-02-26 Daigo Moriwaki <daigo at debian dot org>

        * utils/csa-filter.rb: Allow csa-filter.rb to filter games by a winner or loser
          New command lines, --winner <player> or --loser <player>, are now
          supported to supply extra filtering conditions. Note that each
          filter is combined as AND condition.
          E.g.
          - % ./csa-filter.rb ~/Downloads/20160314 --white gpsfish_xeon --loser gpsfish_xeon
          - % ./csa-filter.rb ~/Downloads/20160314 --white gpsfish_xeon --winner gpsfish_xeon
          (Closes #37023)

2016-12-11  Daigo Moriwaki <daigo at debian dot org>

        * Update Revision to 20161211.
        * Fix Dockerfile.

2016-12-09  Daigo Moriwaki <daigo at debian dot org>

        * Allow util/statistics.rb to set a filtering condition of found files
          Regarding util/statistics.rb, add a new command line option,
          --filter regexp, to process files that are matched with a regexp.
          It would make it easier to calculate statistics of certain games.
          (Closes #36855)

2016-11-26  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] Allow to customize maximum lenght of a login indentifier
          (Closes #36821)
          - The current maximum length of a login identifier is 32. Some
            private uses require longer player names to distinguish each other
            by specifying randomly generated tokens. It would of help to add a
            new command line option --max-identifier to overwrite the default
            maximum length.
        * Build a Docker image for Shogi-server
          (Closes #36822)
          - Build a Docker image
              % make image-build
          - Running a local shogi-server would look like
              % docker pull shogiserver/shogiserver
              % docker run -p 4081:4081 -v `pwd`/logs:/logs shogiserver/shogiserver
        * [shogi-server] shogi_server/game.rb:
          - Remove a debug message

2016-04-09  Daigo Moriwaki <daigo at debian dot org>

        * utils/eval_graph.rb
          - Support Fischer time control.
        * [shogi-server] Bump up the revision to 20160409.

2016-04-02  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] Support Fischer Time Control
          (Closes #36230)
          - Fischer time control means that:
            Before a player has made their move, a specified time increment is
            added to their clock. Time can be accumulated, so if the player
            moves within the delay period, their remaining time actually
            increases.
            (https://en.wikipedia.org/wiki/Chess_clock)
          - New syntax of game names:
            An 'F' suffix denotes a Fisher time in seconds. For example,
            "floodgate-600-10F" specifies
              + A floodgate game
              + Total allotted time is 600 seconds for each player
              + 10-second increment before a player's move in a Fischer way
          - The server now proposes game conditions upon a game start with
            - "Protocol_Version 1.2"
            - "Increment:<n>" for Fischer Time Control
          - Kifu files can include the following comment for Fischer Time
            Control:
            - "'Increment:<n>"
        * [shogi-server] Fix some lint warnings.

2015-12-13  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] Enhance capability of Floodgate configuration file
          - New parameter: Max_Moves, defined in the CSA protocol
            ex. set Max_Moves 256
          - New parameter: Least_Time_Per_Move, defined in the CSA protocol
            ex. set Least_Time_Per_Move 0
          - Proposed messages distributed to each player upon starting a new
            game will include Max_Moves as well as Least_Time_Per_Move.
          - CSA files produced by the server will include settings of
            Max_Moves and Least_Time_Per_Move in comment lines as follows:
              'Max_Moves:256
              'Least_Time_Per_Move:0
          - The official Shogi-server on wdoor.c.u-tokyo.ac.jp will
            be running with different parameters, depending on game names.
            a) Max_Moves will be 256 for floodgate-600-10 games;
               otherwise, 0.
            b) Least_Time_Per_Move will be 0 for floodgate-600-10 games;
               otherwise 1.
          (Closes: #35839)
        * [shogi-server] shogi_server/pairing.rb:
          - LeastDiff attempts more trials, depending of a number of players
            to be matched, top achieve more optimized matching combinations.

2015-11-27  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] shogi_server/time_clock.rb:
          - A time consumed could be -1.
            * The start time of a move is captured after sending a move to a
              player of the next turn at the end of the giant lock
            * The end time of the move is captured at the exact time when the
              server receives it before the giant lock
            Therefore, end_time < start_time is possible when a player returns a
            move instantly.
            Thanks to Tomoyuki Kaneko for reporting this issue.
            (Closes: #35795)

2015-02-14  Daigo Moriwaki <daigo at debian dot org>

        * util/statistics.rb:
          - Updated to investigate floodgate-600-10 games.
            Consult the result at
            http://www.sgtpepper.net/hyspro/diary/20150214.html.
          - Added a companion R script: histogram.R 

2015-02-01  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/login.rb: When players are logged in, log their
            player_id if they have it.

2015-01-20  Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Getting an absolute path of this file was wrong if it was a
            symbolic link. This issue has been addressed.
        * [mk_html]
          - Links to details pages for players now use a relative path so
            that it works on a testing site.

2015-01-17  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi-server, shogi_server/{command,game_result,player}.rb:
            The change at 2014-10-13 was not worked as expected. Reworked.
            A player, attempting to login with the current live player
            stalling for more than a day, can forcibly override the current
            player.

2015-01-12  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server.rb: Follow an API change in a upstream class:
            LogDevice.previous_period_end

2014-12-27  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - When a non-rated player participates in Floodgate, the following exception
            was thrown and a Floodgate game would not start:
              undefined method `[]' for nil:NilClass
              ["/home/shogi-server/www/x/shogi_server/pairing.rb:499:in `block
              in calculate_diff_with_penalty'"
            This issue has been resolved. Only players who have player ID
            (i.e. those who log in with valid password) are now allowed to
            participate in Floodgate as the spec web page
            [http://shogi-server.sourceforge.jp/rating.html] describes.

2014-12-23  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Addressed Ruby incompatibility on ShogiServer::Usi::alphabetToDan.
            It (and usiToCsa.rb) did not work with Ruby 1.9.3. This issue
            has now been fixed.
            Thanks to Hiraoka-san for debugging.

2014-12-18  Daigo Moriwaki <daigo at debian dot org>

        * utils/eval_graph.rb:
          - Gnuplot 4.6.6 drew evaluation-value lines with a dashed style.
            This issue has now been addressed so that solid lines are used.

2014-11-30  Daigo Moriwaki <daigo at debian dot org>

        * [mk_html]
          - Corrected a url.

2014-11-24  Daigo Moriwaki <daigo at debian dot org>

        * Ruby 2.0:
          - Ruby 2.0.0 or later is recommended to use with shogi-server
            since Ruby 1.8 reached its End-of-Life on the end of July, 2014.
        * [shogi-server]
          - Addressed a warning of duplicated range in a regular expression.

2014-10-13  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - A player, attempting to login with the current live player
            stalling for more than a day, can forcibly override the current
            player.
          - Kifu record files now includes rating scores of players at the
            time when games start.  Previously, for rating games, a record
            file includes player IDs of both players with a line starting with
            "'rating".  Now it also shows rating scores for players who have
            valid scores.  The formats for black and white players are as
            follows:
              'black_rate:<player_id>:<score>
              'white_rate:<player_id>:<score>
            A sample output:
              'rating:Test_sente+275876e34cf609db118f3d84b799a790:Test_gote+275876e34cf609db118f3d84b799a790
              'black_rate:Test_sente+275876e34cf609db118f3d84b799a790:2763.0
              'white_rate:Test_gote+275876e34cf609db118f3d84b799a790:2345.0

2014-10-12  Daigo Moriwaki <daigo at debian dot org>

        * [shogi_server]
          - New feature: max moves
            - New command line option: --max-moves n
              When a game with the n-th move played does not end, make the
              game a draw (default 256 in compliance with CSA Protocol V1.2
              or later).  Setting 0 disables this feature for
              CSA Protocol V1.1.2 or before.
            - Players will receive a new message, "#MAX_MOVES", upon an end
              of such a game:
                #MAX_MOVES
                #CENSORED
            - A new log summary type, "max_moves", has been assigned for games
              drawing with max moves.
              'summary:max_moves:name_sente draw:name_gote draw
          - Least time per move:
            - New command line option: --least-time-per-move n
              This option specifies a least time in second per move, which
              is 0 second by default, meaning that a decimal
              fraction of time for a move will be truncated in compliance
              with CSA Protocol V1.2 or later.
              Set 1 for CSA Protocol V1.1.2 or before.

2014-07-19  Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Added a new option, --abnormal-threshold n:
            Games that end with the 'abnormal' status are counted in
            win/lost games for the rating calculation if a game plays more
            than n plies. Otherwise (or if n is zero), abnormal games are
            counted out of rating games.

2014-01-07  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Released: Revision "20140107"

2013-12-29  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Previously, parameters in Floodgate time configuration file were
            not applied to actual instances. This issue has been fixed.

2013-12-21  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/pairing.rb: Impose penalty on matches between
            likely kin players.

2013-12-15  Daigo Moriwaki <daigo at debian dot org>

        * [webserver]
          - Listen on only IPv4 explicitly. Under ruby 1.9.3p194, without
            any bind addresses, ruby attempts to listen on both "0.0.0.0"
            and "::". Specifying "::" on Linux leads to listen on both IPv4
            and IPv6, which results in a warning message saying "Address
            already in use - bind(2)".
        * [shogi-server]
          - Released: Revision "20131215"

2013-12-14  Daigo Moriwaki <daigo at debian dot org>

        * [usiToCsa]
          - Added a new program, bin/usiToCsa.rb, which is a bridge for a
            USI engine to connect to the Shogi-server.
          - bin/usiToCsa is a sample wrapper script.

          - shogi-server/shogi_server/pairing.rb:
            - Modified comment for LeastDiff match.
            - Changed log messages and levels. 

2013-12-07  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/pairing.rb, player.rb:
            Simplify estimated rate of unrated players (less memory).
          - Enhanced syntax of Floodgate time configuration file.
            Now it supports "set sacrifice <player_id>"; it sets a
            sacrificed player for a specific Floodgate game.
            ex. set sacrifice gps500+e293220e3f8a3e59f79f6b0efffaa931

2013-12-05  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Added a new pairing method, ShogiServer::ExcludeUnratedPlayers,
            which filters out unrated players.
          - Enhanced syntax of Floodgate time configuration file.
            Now it supports "set pairing_factory <function_name>"; it sets a
            factory function name generating a pairing method which will be
            used in a specific Floodgate game.
            ex. set pairing_factory floodgate_zyunisen 
          - Implemented conversion of move representation between CSA format
            and USI one.

2013-11-24  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/league/floodgate.rb: Improved robustness against
            empty file under ruby 1.9.3p194
          - shogi-server:
            - Previously, reloading in daemon mode failed on
              ruby 1.9.3p194. This issue has been fixed.
            - Listen on only IPv4 explicitly. Under ruby 1.9.3p194, without

        * [mk_game_results]
          - Fixed for reading Japanese comments under ruby1.9.3p194.
        * mk_rate-from-grep, mk_rate-grep:
          - Removed files that are no longer used.

2013-11-23  Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - gsl library may be provided as a gem
          - Now duplicated inputs are checked and skipped.
        * test/TC_floodgate.rb
          - Improved randomness check so that it works on Ruby 2.0.0 as well

2013-11-04  Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Added a new option, --ignore, which is imported from
            mk_rate-from-grep.
        * [mk_game_results]
          - Flush after each output line.

        * [shogi-server]
          - shogi_server/{game,time_clock}.rb:
            When StopWatchClock is used, "Time_Unit:" of starting messages
            in CSA protocol supplies "1min".

2013-04-07  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/{game,time_clock}.rb:
            Adds variations of thinking time calculation: ChessClock
            (current) and StopWatchClock (new).
            StopWatchClock, which is usually used at official games of human
            professional players, is a clock where thiking time less than a
            miniute is regarded as zero.
            To select StopWatchClock, use a special game name with "060"
            byoyomi time. ex. "gamename_1500_060".

          - %%FORK command: %%FORK <source_game> [<new_buoy_game>] [<nth-move>]
            The new_buoy_game parameter is now optional. If it is not
            supplied, Shogi-server generates a new buoy game name from
            source_game.
          - command.rb: More elaborate error messages for the %%GAME command.

          - New pairing algorithm: ShogiServer::Pairing::LeastDiff
            This pairing algorithm aims to minimize the total differences of
            matching players' rates. It also includes penalyties when a match
            is same as the previous one or a match is between human players.
            It is based on a discussion with Yamashita-san on
            http://www.sgtpepper.net/kaneko/diary/20120511.html.

        * [shogi-server]
          - New command: %%FORK <source_game> <new_buoy_game> [<nth-move>]
            Fork a new game from the posistion where the n-th (starting from
            one) move of a source game is played. The new game should be a
            valid buoy game name. The default value of n is the position
            where the previous position of the last one.
            - The objective of this command: The shogi-server may be used as
            the back end server of computer-human match where a human player
            plays with a real board and someone, or a proxy, inputs moves to
            the shogi-server. If the proxy happens to enter a wrong move,
            with this command you can restart a new buoy game from the
            previous stable position.

        * [shogi-server]
          - shogi_server/login.rb: Enhanced the CSA Login mode.
            Logging in the server with the CSA mode, users are now allowed to
            specify a turn preference in an enhanced gamename string which
            looks like <gamename>-<time>-<time>-<turn>. The first three 
            parts are a regular game definition. The last "-<turn>"
            part is optional. 
            + Without -<turn> (i.e. same as the previous behavior), there
            is no turn preference. A user's turn will be defined randomly. 
            + <turn> is either "B" for black or "W" for white.

        * [shogi-server]
          - shogi_server/{board,command,game,league,player}.rb
            The Buoy behavior is changed.
            + Starting a buoy game, players are notified a starting game
              position with the initial position and moves, instead of a
              targeting position.
            + Players are allowed to start buoy games with specific turns.
              ex. %%GAME buoy_foo-1500-0 +

          - sample/{check_file.rb,check_time.rb,check_time2.rb,test_time.rb}:
            Added new files to test an issue where mtime of log files was
            earlier than system time.
          - shogi_server/league/floodgate_thread.rb: SetupFloodgate#start
            now returns an instance correctly.
          - ../shogi_server.rb, ../shogi_server/util.rb: Refactored
            mkdir_for to Mkdir.mkdir_for.
          - ../shogi_server/game.rb: mkdir_p will be performed in a global
            mutex of ShogiServer::Mkdir.

        * [shogi-server]
          - shogi_server/command.rb: 
            + For an unknown error command log, an empty line is no longer logged.
            + Commands specific to 81Dojo, starting with '%%%', are just
              ignored instead of unknown command errors.
          - shogi_server.rb: 
            + Refactoring. Added test/TC_logger.rb to test
              ShogiServer::Logger class.
            + Fixed race condition: creating a new directory to archive
              logs may have caused race condition, which ended up with
              making the server unavailable. This issue has been fixed. 
          - shogi-server:
            + Improved fault tolerance of the server.

        * [shogi-server]
          - shogi_server/league/floodgate_thread.rb: When the server run
            with DEBUG mode, it ended up with an undefined variable error. 
            This issue has been fixed.

2010-07-17  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server.rb, shogi_server/board.rb, shogi_server/move.rb
            - Refactoring: Board can now move_to() and move_back() a move
              instead of deep_copy().

2010-07-11  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/player.rb: Set initial values to BasicPlayer's
            instance variables.
          - shogi_server/league.rb: Improved performance of
            Persistant#get_players. It took about 20 seconds for a large
            size of players (5,300 lines in players.yaml). Now it completes in an
            instance.

2010-06-22  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - A new command line option: 
              --floodgate-names GameStringA[,GameStringB[,...]]
            where a game string should be a valid game name such as
            floodgate-900-0.  
            .
            Note: Without this option, no floodgate games are started. If
            you want floodgate-900-0 to run, which was default enabled in
            previous versions, you need to specify the game name in this new
            option.
          - Floodgate time configuration file:
            You need to set starting times of floodgate groups in
            configuration files under the top directory. Each floodgate
            group requires a corresponding configuration file named
            "<game_name>.conf". The file will be re-read once just after a
            game starts. 
            .
            For example, a floodgate-3600-30 game group requires
            floodgate-3600-30.conf.  However, for floodgate-900-0 and
            floodgate-3600-0, which were default enabled in previous
            versions, configuration files are optional if you are happy with
            default time settings.
            File format is:
              Line format: 
                # This is a comment line
                DoW Time
                ...
              where
                DoW := "Sun" | "Mon" | "Tue" | "Wed" | "Thu" | "Fri" | "Sat" |
                       "Sunday" | "Monday" | "Tuesday" | "Wednesday" | "Thursday" |
                       "Friday" | "Saturday" 
                Time := HH:MM
             
              For example,
                Sat 13:00
                Sat 22:00
                Sun 13:00

2010-05-06  Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Previously mk_rate did not count in draw games. Now a draw game
            is considered to weight 0.5 win and 0.5 loss. Respect
            Inaniwa-shogi which strategically aims to draw.
          - a new command line option, --skip-draw-games. In this mode, draw
            games are just ignored as mk_rate previously did.

2010-04-25  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/player.rb:
            Log a warning message in a case that a player closes a
            connection suddenly.

2010-04-13  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/command.rb:
            Equality of MonitorHandler class was wrong. %%MONITOROFF and
            %%MONITOR2OFF may cause unexpected behavior. This issue has been
            fixed. Thanks to Kota Fujiwara for reporting.

2010-03-07  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - If two sequential moves from a player are identical, the last
            one will be ignored and a game is in play. This situation might
            happen with human players, especially on slow network,
            impatiently sending a move twice. 

2010-02-27  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The server now provides more accurate time control. Previously,
            a player's thinking time included a time waiting to get the giant
            lock. This may have caused games to time up, especially, during
            byo-yomi etc.

2010-01-22  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Experimental feature: support handicapped games.
            Game names that have the following prefixes are recognized as
            handicapped games. Turn symbols "+" and "-" mean Uwate (expert)
            and Shitate (beginner) respectively (i.e. Uwate players first).

2010-01-16  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/command.rb, test/TC_command.rb
            Proposal implementation of a new command called MONITOR2{ON,OFF}.
            When the MONITOR2ON command is issued by a player, the server
            immediately sends the player the entire contents of a record
            file of the game, i.e. history of moves and so on, at that time.
            Then, the server will forward subsequent moves like they are
            appended to the record file.
          - Behavior changed: A player monitoring a game with MONITORON will
            not receive Game#show again when a gaming player resigns (:toryo).

        * Converted the repository from Subversion to Git.

2009-12-26 Daigo Moriwaki <daigo at debian dot org> 

        * [shogi-server]
          - The server can now provide multiple floodgate modes such as
            floodgate-900-0 and floodgate-3600-0.

2009-12-25 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi-server: The command line option --floodgate-history has
            been deprecated. The server will decide history file names such
            as 'floodgate_history_900_0.yaml' and
            'floodgate_history_3600_0.yaml', and then put them in the top
            directory.

2009-12-20 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/player.rb: Added new methods: is_human? and
            is_computer?. 
            A human player is recommended to use a name ending with '_human'.  
            ex. 'hoge_human', 'hoge_human@p1'
          - shogi_server/pairing.rb: Added a new class:
            StartGameWithoutHumans, which tries to make pairs trying to
            avoid a human-human match. This is now enabled instead of the
            previous class: StartGame.
          - shogi-server, shogi_server/league/floodgate.rb:
            Changed the argument of Floodgate.new.

2009-12-04 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The HUP signal is not supported by Ruby on Windows.

2009-11-11 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Added a new command line option: --base-date. You can specify a
            base date to calculate rating scores. Games in the `future' are
            ignored for the calculation.

2009-11-10 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The server logs a result of each game to a file named '00LIST',
            which will be used to generate players.yaml. If the file does
            not exist, the server will create one automatically.
            Instruction to use the game result list file:
            1. Make a list of game results from existing CSA files with
               mk_game_results
               % ./mk_game_results dir_of_csa_files > 00LIST
            2. Run the server. It appends a result of each game to
               '00LIST' when the game finishes.
            3. From the list of game results, calculate rating scores of
               players.
               % ./mk_rate 00LIST > players.yaml

2009-11-08 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Split a pre-process collecting game results from csa files into
            a new command, mk_game_results. Now, Generating players.yaml
            requires two steps as follows:
              % ./mk_game_results dir_of_csa_files > 00LIST
              % ./mk_rate 00LIST > players.yaml
              or
              % ./mk_game_results dir_of_csa_files | ./mk_rate > players.yaml 
            (Closes: #19454)

2009-08-06 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - A experimental new feature, codenamed Buoy: it allows players to
            play a game starting with a specified position. First, a player
            sets a buoy game with moves to a specific position. Then, two
            players can play a new game with the game name.
            New commands:
            + %%SETBUOY <game_name> <moves> [count]
              Set a new buoy game.
              ex. %%SETBUOY buoy_foo-900-0 +7776FU 10
              ex. %%SETBUOY buoy_foo-1500-0 +7776FU-3334FU
              - game_name is a valid game name with a prefix "buoy_".
              ex. buoy_foo-900-0
              - moves are initial moves from the Hirate position to a
              specific position that you want to start with.
              ex. +7776FU-3334FU+8786FU
              - count is an optional attribute to tell how many times the
              game can be played (default 1). The count is decremented
              when the game finishes. If the count reaches zero, the buoy
              game is removed automatically by the server.
              ex. 10
            + %%DELETEBUOY <game_name>
              Delete a buoy game. The only owner who set up the game is
              allowed to delete it.
              ex. %%DELETEBUOY buoy_foo-900-0
              - game_name is the buoy game name that was created.
            + %%GETBUOYCOUNT <game_name>
              Show a current count of the buoy game or -1 for non-existing
              games.


2009-07-11 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/command.rb: refactored commands out of player.rb.

2009-06-18 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - An empty floodgate_history.yaml caused a server error. This
            issue has been fixed. 
            (Closes: #15124)

2009-06-17 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - If a new game matched between two players is not started within
            a certain time (default 120 seconds) (i.e. the agree_waiting or
            start_waiting state lasts too long), the Server REJECTs the game.
            (Closes: #14425)

2009-06-15 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - When a Gote player AGREEd a new game and then a Sente player
            logged out (LOGOUT), the Gote incorrectly received a LOGOUT message 
            from the server. Since Gote's state was not AGREEd or STARTed yet,
            the Gote should be REJECTed. This issue has been fixed. 
            (Closes: #17335)

2009-06-14 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The Board could not recognize a certain pattern of
            Oute-Sennichite. This issue has been fixed.
            (Closes: #13966)

2009-03-22 Daigo Moriwaki <daigo at debian dot org>

        * [utils/correct-bug14635.rb]
          - Added a new file. This program corrects illegal lines introduced
            by the #14635 bug.

2009-03-07 Daigo Moriwaki <daigo at debian dot org>

        * [csa-file-filter]
          - Improved performance.

2009-02-15 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - A duplicated comment that is the one of the previous (or older)
            move might be erroneously recorded in a csa file. This issue has 
            been fixed. (Closes: #15080)

2009-02-11 Daigo Moriwaki <daigo at debian dot org>

        * [utils/csa-filter.rb]
          - Added a new file. This program filters CSA files.

2009-02-01 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The shogi-server records csa files of games in an illegal
            format. This issue has been fixed. (Closes: #14635)
          - A ##[MONITOR] command for showing a game result such as %TORYO
            was not correct. This issue has been fixed.  

2009-01-13 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - It failed to proccess a game result, OuteKaihiMoreWin where a
            checked king does not escape. This issue has been fixed.

2009-01-02 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - shogi_server/timeout_queue.rb: the timeout parameter of the
            constructor was not respected erroneously. This issue
            has been fixed.
          - shogi_server/players.rb: When a player was finishing with its
            write socket broken, there was a chance that the thread of the
            player in the giant lock had to wait for a long time (about 20
            seconds), which might cause threads of other players stop and 
            time out. (Closes: #14469)

2008-12-30 Daigo Moriwaki <daigo at debian dot org>

        * [mk_html]
          - Added a new option: --footer filename, which inserts contents of 
            the filename at the bottom of a generated page. A text specific to 
            wdoor should be written by using this option. 
            (Closes: #14470)
          - It does no more depend on RDoc. RDoc::usage does not work well
            (due to RDoc).

2008-12-28 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Check kifu files more carefully so that files that contain
            incomplete records are skipped.
          - mk_rate might have failed to alloc due to out of memory. Now it
            consumes less memory (about 200MB instead of 2GB).
          - File names can be put into STDIN instead of specifying directory
            names in command line arguments.
        * [csa-file-filter]
          - New file. It filters kifu files and is of use for a pre-filter
            of mk_rate.

2008-12-13 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Improved an existance check and etc. of directories specified
            by command line options, especially in case of the daemon mode. 
            (Closes: #14244)
          - A rotated log file is moved to $topdir/YYYY/MM/DD.
            (Closes: #14245)

2008-11-27 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Added sample/*.sh for command line samples.

2008-11-24 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Added a new option --floodgate-history, which allows users to
            specify a file name that stores the records of games. The
            records are taken care of when games are matched.

2008-10-18 Daigo Moriwaki <daigo at debian dot org>

        * [utils/eval_graph.rb]
          - Display time control graphs as well.
            Thanks to Nishimura-san for this idea.
            (Closes: #13678)

2008-10-08 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Ruby 1.8.7 (or later) must be used. Ruby 1.8.6 is not supported.
          - Daemon mode is available.
          - shogi_server/piece_ky.rb is again merged with
            shogi_server/piece.rb, then has been removed.  
          - Added a test case, TC_usi.rb.

2008-06-30 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Added a new option --player-log-dir, which allows users to log
            messages that are received or sent to the wire.

2008-06-28 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - A rating comment line is now written before the first move in a
            record file instead of after the last move, which allows other
            applications watching a game to recognize players in the middle 
            of the game. (Closes #12821)
          - If a player, including a monitor, stuck at the time of sending
            messages to the wire, which means that the giant lock was locked,
            it might have prevented other players from processing until
            timeout occurred. This issue has been fixed. (Closes #12555)

2008-06-27 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          -  Pairing players might not have shuffled players because of
             poor shuffling algorithm. This issue has been fixed.
             (Closes: #12661)

2008-06-25 Daigo Moriwaki <daigo at debian dot org>

        * [players_graph.rb]
          - Check invalid arguments. (Closes: #12856)

2008-06-23 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - Added a new option: --fixed-rate and --fixed-rate-player
            whose rate always results in that rate. (Closes: #12800)

2008-06-06 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The source has been splited to multiple sub files.
          - The program now depends on rubygems and activesupport.
          - The program can reload the source files on the flight, by
            sending a HUP signal to the server.
          - The server log will be rotated daily.

2008-05-18 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Last game results (win or lose) of x1 players were not
            available on the next game. This issue has been fixed.
            Thanks to Tomoyuki Kaneko for debugging.
          - For draw games, "'rating" line in a .csa file was 
            wrong (meaningless). This issue has been fixed.

2008-05-16 Daigo Moriwaki <daigo at debian dot org>

        * [news]
          - The repository has been converted from CVS to Subversion.

2008-05-13 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Floodgate's thread could cause an error when players.yaml was
            cleared by another program (mk_rate). This issue has been 
            fixed.
          - Give default values to BasicPlayer, which fixed undefined 
            method error in Pairing.

2008-05-10 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The server could not recognize uchifuzume as an illegal move.
            This bug has been fixed.
          - The server crashed by an undefined method error.
            This issue has been fixed.

2008-05-05 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - .csa files will be located in a sub directory such as
            "2008/05/05/*.csa". These days, we have many games in a day. 
            This change will help users browse a file list.

2008-05-03 Daigo Moriwaki <daigo at debian dot org>

        * [mk_html]
          - Show players who have accessed in the last 30 minutes with 
            different colors.

2008-04-22 Daigo Moriwaki <daigo at debian dot org>

        * [mk_html]
          - When YSS was not rated on the wdoor mode, wrong rate24 scores
            were displayed. This issue has been fixed. Now YSS absence 
            results in "N/A".

2008-04-21 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - The half-life period is now configurable.
            ex $ ./mk_rate --half-life 14 --half-life-ignore 7 <records>

2008-04-12 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Renamed variables (@id) since they caused Ruby's warning.

2008-04-11 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Improved a way to handle diferred moves (2008-03-24's change),
            based on Tomoyuki Kaneko's patch.

2008-04-01 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - An incorrect LOGIN crashed the server. This issue has been
            fixed.

2008-03-24 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Converting characters for comments in moves caused an error. This 
            issue has been fixed.
          - If a player moves in the opponent's turn, it is illegal. But the
            current CSA protocol does not clearly define a way to tell so to 
            the players. This shogi-server internally keeps such a move in a
            buffer and replay it when the player of the move gets his/her 
            turn.

2008-03-16 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Erroneously, Board#to_s's current player was always Black.
            It caused wrong determination of sennichite since it did not
            care about the current player of a state. This has been fixed.
            Thanks Takada-san for reporting this bug.

2008-03-10 Daigo Moriwaki <daigo at debian dot org>

        * [util/players-graph.rb]
          - Applied Kaneko-san's patch, which also shows expected-rate24
            rates.
          - Small PNG gets smaller.

2008-03-08 Daigo Moriwaki <daigo at debian dot org>

        * [mk_html]
        - Added an option --wdoor. In this mode, a rate expected at Shogi
          Club 24 is calculated from YSS's rating (he is 2400 now). 

2008-03-04 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
          - If the computed ratings do not stabilize, then mk_rate aborts.
              $ ./mk_rate dir && ./mk_rate dir > players.yaml 
            can avoid rewriting the invalid ratings to the file.

2008-02-23 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - A comment is converted to EUC-JP and then written in a log.
            Note that this conversion guesses the input encoding. Clients
            are recommended to send EUC-JP compatible strings to the
            server.

2008-02-21 Daigo Moriwaki <daigo at debian dot org>

        * [util/players-graph.rb]
          - Released. Draw a chart for a player's rating score.

2008-02-17 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - An illegal teban specified for Floodgate login could crash the
            server. This issue has been fixed.

2008-02-16 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Thread.abort_on_exception is now false, meaning that 
            a thread's abort does not affect the others. 
          - The uchifuzume check did not generate promoting moves, which
            could crash the server with illegal moves. This issue has
            been fixed.

2008-02-14 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Added a new pairing variation, Swiss-like style. Winners at the
            previous games (his/her point of view, not the server's) are 
            paired first, and then the others are matched. This is the 
            default option now.
          - Pairing classes are located in a separate source file,
            pairing.rb. The file is 'load'ed each time to be used,
            meaning that modifying the code will be applied to a running
            server.
          - You can specify a single player who will be out of pairing
            when there are odd players waiting for Floodgate.

2008-02-13 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - When there are odd players wating for Floodgate, the random
            pairing deletes the player who has ever played the most games.

2008-02-08 Daigo Moriwaki <daigo at debian dot org>

        * [ml_html]
          - For the Not-Yet-Rated group, those who have not connected
            recently are not listed.
        * [shogi-server]
          - Floodgate's thread checks the current time each 10 secs.

2008-02-05 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate] [mk_html]
          - Display not-yet-rated players as well.
        * [mk_html]
          - Use Yahoo! UI Library.

2008-02-04 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server] [webserver]
          - In the daemon mode, if the specified directory was a relative
            path, the server could fail to start with a permission denied
            error. This issue has been fixed. The path is interpreted as 
            an absolute path before switching to daemon. 
          - In the daemon mode, a wrong process id was written in 
            '--pid-file'. This issue has been fixed. Also, the pid file
            will be removed when the server shuts down.

2008-02-03 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Game names that are recognized as the floodgate mode are now 
            /^floodgate-\d+-\d+$/.
          - Floodgate could not schedule the next time when it was the next
            day. This issue has been fixed.

2008-02-02 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Implemented a new feature, Floodgate mode, for covenience with
            public rating games. Now there is a special game "wdoor-900-0".
            Matching players for that game is scheduled each 30 minitues.

2007-11-03 Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate]
         - Support Ruby 1.8.6 patch level 111 (or higher) and GSL 1.10 (or higher).
           It may not work with lower verions. 

2007-09-06 Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - The logic to detect Oute-Sennichite was not complete. Both players
            (checking side and escaping side) may cause Oute-Sennichite. The old
            logic only cared for the checking player. This issue has been fixed.

2007-06-16  Daigo Moriwaki <daigo at debian dot org>

        * [webserver]
          - Initial version. This web server is an interface between HTTP and
            shogi-server. Shogi-server commands will be available over HTTP. As
            of now %%LIST and %%WHO commands are supported.
        * [mk_rate]
          - Bumped up GAME_LIMIT (from 10) to 15 because the calculation of
            rates sometimes went wrong (infinite values).

2007-04-21  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]
          - Implemented `CHALLENGE' command, and the server will respond with
            `CHALLENGE ACCEPTED'. Note that this command is dummy for this server
            because it is only available for CSA's official testing server and does
            not belong to the CSA standard protocol.  Therefor, when clients receive
            `CHALLENGE ACCEPTED' from this server, they must ignore it.
          - Show revision in a start up message.

2007-04-01  Daigo Moriwaki <daigo at debian dot org>

        * [shogi-server]

            send LF, the server sends back LF.
          - More care for socket errors.

        * [mk_rate] When there were too few games to rate players (i.e. no

        * [mk_rate] Skip "abnormal" games, which were finished because of
          network failure or communication error.  Recently some programs seem
          to have a lot of tries to connect to the Shogi Server at wdoor for
          debugging. We should ignore such games for a while to get a meaningful
          ratings.

2006-10-30  Daigo Moriwaki <daigo at debian dot org>

        * [mk_rate][mk_html]
