Jonathan Oddy f2dccb90e8 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.		2018-10-12 12:31:24 -07:00
