bugfixes:
    - Restore SIGPIPE to SIG_DFL when creating subprocesses to avoid it being ignored under Python 2.
Restore SIGPIPE handler to DFL on POpen Python sets the SIGPIPE handler to SIG_IGN. On execv() signal handlers are reset to their defaults, EXCEPT those that are SIG_IGN which are left ignored. In Python 3 subprocess.popen explicitly resets the SIGPIPE handler to SIG_DFL, but unfortunately in Python 2.7 it does not. This leads to subprocesses being executed with SIGPIPE ignored. This is often a problem with bash scripts which rely on SIGPIPE to terminate commands in a pipe, but can easily be a problem with other applications. This implements the Python 3 behaviour for Python 2.7 by using a preexec_fn. 2018-08-03 18:35:34 +02:00			`bugfixes:`
