Some potential bug report.

The python-client can not work on the Ubuntu. Are your environment Windows? Because the python behavior may be difference between two OS. I want to check it first. Thanks!

[zakki]

Maybe it's because of difference between python 2 and 3. Could you try develop HEAD?

[CGLemon]

Thanks! The last python-client is working. But my server said the db.execute(...).fetchone() is None type.

cgos/server-python/cgos/app/cgos.py

Lines 1394 to 1396 in 5202119

	gid = db.execute(
	"SELECT gid FROM gameid WHERE ROWID=1"
	).fetchone()[0]

The error report is

TypeError: 'NoneType' object is not subscriptable

What's possible wrong with it?

[zakki]

Perhaps this insert statement during initialization failed.

cgos/server-python/cgos/app/cgos.py

Line 192 in 5202119

conn.execute("INSERT into gameid VALUES(1)")

Manualy sqlite3 /home/cgosboar/19x19/cgos.state and INSERT into gameid VALUES(1); would fix it.

I got that error once, but I dont' have detail yet.

I added commit() to other update statements.

The GTP client must read the stderr string. If stderr buffer is full, the client may not read stdout string.

OS: Ubuntu 20.04
python version: 3.8

Default paramter of subprocess.Popen is stderr=None, so I think that AI's stderr is just redirected to cgos client's stderr.

Do you use stderr=subprocess.PIPE?

[CGLemon]

Sorry, I suffered this issue in my project. So I guess there is a same issue here. It is my mistake.
