Banksia GUI released

[CMCanavessi]

I've found another issue with pondering, but I don't know if it's a Minic thing or a Banksia thing

//MINIC LOSES ON TIME//

After DanaSah 8.8 moves (and Minic does NOT guess the correct move), Minic is told to stop, returns the bestmove, but then Banksia doesn't send the new position and go command...

Edit: tried some more games, looks like sometimes Banksia ignores Minic's reply... Here's the full log of one of those matches:

Edit2: in both games, Banksia just ignored Minic's bestmove O-O-O. Can it be that Banksia is filtering the "O-O-O" string out?

Banksia correctly ignores the response. Stop is sent to the pondering engine when the pondering move is wrong... The engine responds with a "best"move only to comply with the protocol. And then banksia MUST send another go request to the engine with the start position and the moves, and a go command. If this is not done, then the bug is in the GUI else it is in the engine.

You can test Banksia's implementation against my engine Zahak, if Zahak also had issues then I'm sure it is a GUI bug

Yes, I know how it should work. What I mean is that maybe banksia is filtering Minic's bestmove after the stop command and then waits forever to receive the bestmove that it just filtered out (for whatever reason). Still, if you look at the full log that I posted from the other game, Banksia again ignores Minic's bestmove and that one wasn't while pondering, it was just a regular move.

As Banksia works ok with all other engines, there must be something that Minic is doing different (wrong or right I don't know, but definitely there's something different). I suspect that castling string.

Actually you are absolutely right, castling should be written as e8c8, e1c1, e1g1 and e8g8...
So, Banksia cannot parse 0-0-0 (which is a PGN notation, not algebraic notation -- which is what is required by UCI)
Now wondering, how the hell Minic works at all? it is either never castles, or whenever it castles it disconnects?

[CMCanavessi]

Well, remember I'm testing FRC. Maybe Minic works ok in normal chess, but has problems with FRC notation, and/maybe cutechess or other GUIs can parse the O-O-O notation even if it's not compliant.

Thanks for the analysis, i'll fix that.

[CMCanavessi]

Thanks for the analysis, i'll fix that.

Well, your fix seems to have worked fine. Minic is not losing on time anymore because of the castling string. However, it is still losing on time (not quite often though), due to some other reason. A couple of logs below:

I think that info string with the "empty pv" between the stop command and the bestmove may be the culprit. Can you try to invert it, first send the bestmove one and then the info string, or just remove that info string so I can test? If that works, then you can find a work-around.

Minic has received a stop just after a go ponder, so it as no best move to output and says

Code: Select all

321.09:09:40 Minic 3.10> bestmove 0000

But indeed, it is logging a little more before that with

Code: Select all

321.09:09:40 Minic 3.10> info string Warn  2021-08-04 09:09:40-609: Empty pv

and Banksia isn't asking for a new search as it should.

This will happen quite a lot, against any engine that is insta-moving on ponderhit.

Do you think Banksia does not like "free style" info string ?

Do you think Banksia does not like "free style" info string ?

I think that Banksia expects a bestmove string right after the stop command (does the UCI protocol say anything about that?), and as it's receiving an info string instead, things break.

Well, I just went and looked:

* stop

stop calculating as soon as possible,

don't forget the "bestmove" command and possibly the "ponder" token when finishing the search

Ambiguous as sh1t lol. Doesn't say that engine must send "bestmove" immediately, but doesn't say it can send other things either lol. I might guess that Banksia may get confused by that info string (not because I know Banksia, but because it works ok with other engines that don't send it).

Not to forget in "info" subsection:

* string <str>
any string str which will be displayed be the engine,
if there is a string command the rest of the line will be interpreted as <str>.

But maybe there is a pretty clean solution using the

* debug [ on | off ]
switch the debug mode of the engine on and off.
In debug mode the engine should send additional infos to the GUI, e.g. with the "info string" command,
to help debugging, e.g. the commands that the engine has received etc.
This mode should be switched off by default and this command can be sent
any time, also when the engine is thinking.

Maybe I'm not allowed to log if the engine hasn't send "debug on" ...

I can add that easily for sure!
