the site page is here http://cinnamonchess.altervista.org

Is it possible replace 2.3 with 2.3.1 here? http://ccrl.chessdom.com/ccrl/404/index.html

thanks

Hi Giuseppe,

What are the changes relative to version 2.3 apart from those affecting FRC? In other words, are they identical in normal chess?

Hi Gabor, I fixed only FRC bug, in normal chess 2.3 and 2.3.1 are identical

I'm afraid you have broken something, Giuseppe.

Since I replaced 2.3 with 2.3.1 the engine does not always move when out of external book (Arena GUI, own book not used).

Here are debugs from both of the. I can only see that 2.3. starts calculating while 2.3.1 does not.
Also, please note the lines marked red (by version 2.3):

I can answer at least the first part of this after a little logging.
In your debugs Arena commands arrive not in the expected order (but having the same timestamp).
The debug shows changed options are sent before 'isready/readyok' is processed in Cinnamon!

So Arena issues setoption and isready in random order?

Actually I looked the uci specs up again and after an engine was started with uci it should be able to process
either 'setoption' or 'isready', so I am not sure anymore, why Cinnamon refuses to accept 'setoption' at this time.

Code: Select all

* The engine should boot and wait for input from the GUI,
  the engine should wait for the "isready" or "setoption" command to set up its internal parameters
  as the boot process should be as quick as possible.

I'll leave it to an uci engine programmer and Arena specialist ;-)

Code: Select all

* isready
    this is used to synchronize the engine with the GUI. When the GUI has sent a command or
    multiple commands that can take some time to complete,
    this command can be used to wait for the engine to be ready again or
    to ping the engine to find out if it is still alive.
    E.g. this should be sent after setting the path to the tablebases as this can take some time.
    This command is also required once before the engine is asked to do any search
    to wait for the engine to finish initializing.
    This command must always be answered with "readyok" and can be sent also when the engine is calculating
    in which case the engine should also immediately answer with "readyok" without stopping the search.

Actually I looked the uci specs up again and after an engine was started with uci it should be able to process
either 'setoption' or 'isready', so I am not sure anymore, why Cinnamon refuses to accept 'setoption' at this time.

Engines should definitely handle getting 'setoption' directly after 'uci'. Only guarantee, as the quoted part states, is 1 'isready' before the first 'go'. Whether the 'isready' must be directly before the 'go', or at any point between 'uci' and 'go' I don't know, the specs are poorly written

Cinnamon 2.3 has a bug in Uci module so setoption in uppercase (Hash, etc) don't work properly, this bug has been fixed in 2.3.1.

21.855: > setoption Hash value 512
21.855: < Unknown command: setoption Hash value 512

it's wrong, you have to write "setoption name Hash value 512" don't you?

Gabor I don't understand

Since I replaced 2.3 with 2.3.1 the engine does not always move when out of external book (Arena GUI, own book not used).

may you explain it?

You are absolutely right! Sorry in my first attempt in hasty reproducing the error I forgot it.
Unlike in the second log I showed...

When I played version 2.3 all was well (Cinnamon always moved). Then I replaced it with version 2.3.1 and that engine often refused to move after leaving book. The attached snippets show that: 2.3 is calculating, 2.3.1 is not (that occurs in about half of the games).
