+
+ * [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)

+
+ * 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

+
+ * [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.

+
+ * [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.

+
+ * [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.
+

+
+ * [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.

+
+ * [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

+
+ * [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.

+
+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.
+
+2013-12-13 Daigo Moriwaki <daigo at debian dot org>
+
+ * [shogi-server]
+ - shogi_server/league/floodgate_thread.rb:
+ - Added a log message.
+
+2013-12-08 Daigo Moriwaki <daigo at debian dot org>
+
+ * [shogi-server]
+ - 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
+ 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)".
+ * [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.
+ * Rleased: Revision "20131104"
+
+2013-09-08 Daigo Moriwaki <daigo at debian dot org>
+
+ * [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".
