+
+ * [shogi-server] Improve timed-up detection (continued).
+ The server now checks timed up when it receives a-single-space keep
+ alive messages as well.
+ Thanks to mizar for reports and patches.
+ (Closes #40821)
+ * [shogi-server] Support listening on IPv6 addresses
+ Thanks to mizar for a patch.
+ (Closes #40822)
+ * [shogi-server] Make invalid comments illegal
+ Some client sent moves with comments in an invalid format like
+ "+7776FU '* 30 -3334FU +2726FU". Such messages are now deemed
+ illegal.
+ Thanks to mizar for a report.
+ * [shogi-server] Bump up the revision to 20201206

+
+ * [shogi-server] Improve timed-up detection.
+ Previously, the server checked if a game got timed up when a player
+ in turn sent no message for a certain amount of time mainly defined
+ by Default_Timeout. If the player sent keep alive frequently, the
+ timed-up detection could be quite delayed.
+ This issue has been addressed. The server now checks timed up with
+ keep alive received as well. Players are notified with TIME_UP not
+ long before games gets timed up.

+
+ * [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]
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.
