Hi, I'm wondering what the reason for IgnoreSIGPIPE to default to true is. The documentation just states that
Defaults to true because SIGPIPE generally is useful only in shell pipelines. But I don't think that this alone is a good reason to change the default. It can confuse programs which use pipes and do not expect their signal handlers to be messed with, see [1] for the same issue in Python. As another example, "tar xf *.tar.gz" will fail on some archives if SIGPIPE is ignored[2]. Another problem is that this not only affects the program started by systemd itself, but leaks into all child processes as well. See [3] for a bug report against cron due to this (yes, can be worked around by setting IgnoreSIGPIPE=false for cron.service, but I believe systemd is wrong here). Ansgar [1] <http://bugs.python.org/issue1652> [2] I think the .gz needs trailing zeros in either the compressed or uncompressed data stream. I could look at the file it failed with...
