Windows - PermissionError: [Errno 13] Permission denied

[David]

Hi

When testing out this example in windows:

from logging import getLogger, INFO
from concurrent_log_handler import ConcurrentRotatingFileHandler
import os

log = getLogger(__name__)
# Use an absolute path to prevent file rotation trouble.
logfile = os.path.abspath("mylogfile.log")
# Rotate log after reaching 512K, keep 5 old copies.
rotateHandler = ConcurrentRotatingFileHandler(logfile, "a", 512*1024, 5)
log.addHandler(rotateHandler)
log.setLevel(INFO)

log.info("Here is a very exciting log message, just for you")

It produces this Permission error.

How would I resolve this for running it on windows?

Ahh, just realised now, problem is I'm running the code from synced desktop google drive file.

Yeah, that could do it. The problem is portalocker and the lock file. Using a location on a synced folder like Google Drive, Dropbox, OneDrive, etc, might cause issues.

There is a PR outstanding #50 that will provide a way to specify an alternate lock file location, which could address your issue. I'm planning to tackle that PR after #48 is finished up.
