Subject: Jenkins' job output fix
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=5bd780d3502dda19c9f28d7e84e678199b124e1d;p=tools%2Fsustaining.git

Jenkins' job output fix

sys.stdout.write() does not guarantee that the output will show up,
as buffers need to be explicitly flushed. The more suitable solution is
to use the print_function from __future__.
