Memory leaks

vinc...@legout.info (Vincent Legout) — Sun, 19 May 2013 14:38:36 UT

Hello,

A bug has been reported in Debian, see: [link]

The bug report doesn't give much information but it seems gnuchess leaks
memory. Indeed, running something like:

valgrind --leak-check=full --show-reachable=yes ./src/gnuchess

returns lots of output.

Thanks,

bug in setboard on version 6.0.3

chen...@nextchessmove.com (Chad Hendry) — Mon, 22 Apr 2013 14:56:57 UT

Greetings!

The "setboard" command doesn't seem to be working in 6.0.3. If I run the
following, the engine never comes back with a move:

printf "xboard\nprotover 2\nsetboard

Bug in GNU Chess 4.10 for Windows

buzzbl...@rcn.com (Buzz Bloom) — Fri, 07 Dec 2012 14:47:51 UT

Hi:

The HELP window for the version of GNU Chess 4.10 for Windows I am using
says that the version was ported from GNU Chess 4.0 patch level 77, and
it was compiled with Borland C++.

Several bug behaviors occur using the feature Edit->Review Game. The
first bad behavior I noticed involved an _en passant_ capture. Review

Hi,

Not sure who Matt is, but I would be really glad if this could be looked
into. My use case involves the engine waiting for an opponent most of the
time, and then waiting for him to move most of the time during a match
(ponder=off). The priority is using as little resources as possible, rather

Re: GNU chess seems to always run at 100% CPU

acebal...@gmail.com (Antonio Ceballos) — Sat, 06 Oct 2012 16:50:04 UT

Hi Matt,

GNU Chess 6 uses 100% CPU, it is normal behaviour. Since it is expected to
be playing most of the time, this should not be a big issue. Anyway,
decreasing the CPU usage when the program is in "standby" is certainly an
improvement we should address.

Thanks for your interest.

Hello all,

It seems that regardless of the way I run GNU chess, it consumes 100% CPU
time, even before any commands are issued.
Examples I've tried that all cause this behaviour:
./gnuchess
./gnuchess --easy
./gnuchess --uci

After any of the above, "top" shows gnuchess running at 100% CPU right away

I have verified your report, i.e. that the command below works for GNU
Chess v5, but not for v6, due to the different way to handle the user input.

The obvious way to compile a book in v6 is to run GNU Chess, enter the
'book add <filename>' command, and quit once the book is done. However, I

Re: Cant run gnuchess5.07 on Xboard

Your suggestion---not requiring the .ini file---makes sense. Getting rid of

reasonable. We will consider to include this feature in v6.
