Red Hat Bugzilla – Bug 1236306
Some of dnf's subcommands can't handle pipe
Last modified: 2015-08-19 03:51:34 EDT
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):
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
File "/usr/lib/python2.7/logging/__init__.py", line 843, in flush
IOError: [Errno 32] Broken pipe

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.
