+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 deprectated. 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 recommened 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 instread 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 exisiting 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. %%SETBUOYGAME buoy_foo-900-0 +7776FU 10
+ ex. %%SETBUOYGAME 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
+ spcific 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 emtpy 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 genrated 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, expecially in case of the daemon mode.
+ (Closes: #14244)
+ - A lotated 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". Thease 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.
