Felix Uellendall commented on AIRFLOW-3551:
-------------------------------------------
I think it is not really testable because it is a inner function and I can not
directly access it.
{code:python}
def pre_exec():
# Restore default signal disposition and invoke setsid
for sig in ('SIGPIPE', 'SIGXFZ', 'SIGXFSZ'):
if hasattr(signal, sig):
signal.signal(getattr(signal, sig), signal.SIG_DFL)
os.setsid()
self.log.info('Running command: %s', self.bash_command)
sub_process = Popen(
['bash', tmp_file.name],
stdout=PIPE,
stderr=STDOUT,
cwd=tmp_dir,
env=self.env,
preexec_fn=pre_exec)
{code}
If we move it outside we can test it. You think the `pre_exec` function should
be a public function in the `BaseOperator` ?
