Created attachment 1043883 [details] Result of "dnf group list | head -n 1" Description of problem: Some, for instance list and group, can't handle pipe properly, and throw "[Errno 32] Broken pipe". Others can, for instance info and search, but when used with "head -n 0", go wrong. In this case, I don't think it causes a problem, from a practical viewpoint. Version-Release number of selected component (if applicable): dnf-1.0.1-2.fc22.noarch How reproducible: Always Steps to Reproduce: $ dnf list | head -n 1 Last metadata expiration check performed 0:38:32 ago on Sat Jun 27 23:18:33 2015. [Errno 32] Broken pipe $ dnf search dnf | head -n 0 Traceback (most recent call last): File "/usr/lib/python2.7/logging/__init__.py", line 883, in emit self.flush() File "/usr/lib/python2.7/logging/__init__.py", line 843, in flush self.stream.flush() IOError: [Errno 32] Broken pipe Logged from file cli.py, line 802
Thanks for the report. We'll take a look. Btw yum does that too.
Do you now what's the cause of the problem, Michael?
Python by default does not ignore SIGPIPE. Fixed in commit 0e940a58d13bf4c22d42881cbd3b83bce12adb59 ignore SIGPIPE (RhBug:1236306)
