# Concurrency Warning: use gpodder.util.Popen() instead of subprocess.Popen()
# When using subprocess.Popen() to spawn a long-lived external command,
# such as ffmpeg, be sure to include the "close_fds=True" argument.
# This is expecially important for extensions responding to
# on_episode_downloaded(), which runs whenever a download finishes.
# Otherwise that process will inherit ALL file descriptors gPodder
# happens to have open at the moment (like other active downloads).
# Those files will remain 'in-use' until that process exits, a race
# condition which prevents gPodder from renaming or deleting them on Windows.
# Caveat: On Windows, you cannot set close_fds to true and also
# redirect the standard handles (stdin, stdout or stderr). To collect
# output/errors from long-lived external commands, it may be necessary
# to create a (temp) log file and read it afterward.
You can’t perform that action at this time.
