From: Tony Jones Date: Fri, 22 Feb 2019 15:06:14 -0800 Subject: perf script python: Add Python3 support to sctop.py Origin: https://git.kernel.org/linus/ee75a896ae535d4219a82cc361be96394536f3ba Bug-Debian: https://bugs.debian.org/944641 Support both Python2 and Python3 in the sctop.py script There may be differences in the ordering of output lines due to differences in dictionary ordering etc. However the format within lines should be unchanged. The use of 'from __future__' implies the minimum supported Python2 version is now v2.6 Signed-off-by: Tony Jones Cc: Tom Zanussi Link: http://lkml.kernel.org/r/20190222230619.17887-11-tonyj@suse.de Signed-off-by: Seeteena Thoufeek Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/scripts/python/sctop.py | 24 ++++++++++++++++-------- 1 file changed, 16 insertions(+), 8 deletions(-) --- a/tools/perf/scripts/python/sctop.py +++ b/tools/perf/scripts/python/sctop.py @@ -8,7 +8,14 @@ # will be refreshed every [interval] seconds.
