Logging error: [Errno 9] Bad file descriptor

Using the logging module inside pyhidra generates exceptions: with a simple test script like the following (named logme.py)

import logging

Log_Format = "%(levelname)s %(asctime)s - %(message)s"

logging.basicConfig(filename="/tmp/ghidra_abstract.log", filemode="a", format=Log_Format, level=logging.DEBUG)
logger = logging.getLogger(__name__)

def something():
    logger.info("miao")

and calling something() inside the ghidra's pyhidra window

>>> import logme
>>> logme.something()
--- Logging error ---

    logger.info("miao")
Message: 'miao'
Arguments: ()

where in a normal execution inside a normal python intepreter you have

In [1]: import logme

In [2]: logme.something()

In [3]:

and then

$ cat /tmp/ghidra_abstract.log 
INFO 2022-12-24 12:51:37,032 - miao

This is probably caused by a closed stdout: still inside pyhidra terminal you can generate the same error

>>> os.write(1, b"miao")
