perf script python: Add Python3 support to failed-syscalls-by-pid.py Support both Python2 and Python3 in the failed-syscalls-by-pid.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 <to...@suse.de> Cc: Tom Zanussi <tzanu...@gmail.com> Link: http://lkml.kernel.org/r/20190222230619.17887-5-to...@suse.de Signed-off-by: Seeteena Thoufeek <s1see...@linux.vnet.ibm.com> Signed-off-by: Arnaldo Carvalho de Melo <a...@redhat.com> --- tools/perf/scripts/python/failed-syscalls-by-pid.py | 21 +++++++++++---------- 1 file changed, 11 insertions(+), 10 deletions(-) diff --git a/tools/perf/scripts/python/failed-syscalls-by-pid.py b/tools/perf/scripts/python/failed-syscalls-by-pid.py index cafeff3d74db..3648e8b986ec 100644 --- a/tools/perf/scripts/python/failed-syscalls-by-pid.py +++ b/tools/perf/scripts/python/failed-syscalls-by-pid.py @@ -5,6 +5,8 @@ # Displays system-wide failed system call totals, broken down by pid. # If a [comm] arg is specified, only syscalls called by [comm] are displayed. +from __future__ import print_function + import os import sys @@ -32,7 +34,7 @@ if len(sys.argv) > 1: syscalls = autodict() def trace_begin(): - print "Press control+C to stop and show the summary" + print("Press control+C to stop and show the summary") def trace_end(): print_error_totals() @@ -57,22 +59,21 @@ def syscalls__sys_exit(event_name, context, common_cpu, def print_error_totals(): if for_comm is not None: - print "\nsyscall errors for %s:\n\n" % (for_comm), + print("\nsyscall errors for %s:\n" % (for_comm)) else: - print "\nsyscall errors:\n\n", + print("\nsyscall errors:\n") - print "%-30s %10s\n" % ("comm [pid]", "count"), - print "%-30s %10s\n" % ("------------------------------", \ - "----------"), + print("%-30s %10s" % ("comm [pid]", "count")) + print("%-30s %10s" % ("------------------------------", "----------")) comm_keys = syscalls.keys() for comm in comm_keys: pid_keys = syscalls[comm].keys() for pid in pid_keys: - print "\n%s [%d]\n" % (comm, pid), + print("\n%s [%d]" % (comm, pid)) id_keys = syscalls[comm][pid].keys() for id in id_keys: - print " syscall: %-16s\n" % syscall_name(id), + print(" syscall: %-16s" % syscall_name(id)) ret_keys = syscalls[comm][pid][id].keys() - for ret, val in sorted(syscalls[comm][pid][id].iteritems(), key = lambda(k, v): (v, k), reverse = True): - print " err = %-20s %10d\n" % (strerror(ret), val), + for ret, val in sorted(syscalls[comm][pid][id].items(), key = lambda kv: (kv[1], kv[0]), reverse = True): + print(" err = %-20s %10d" % (strerror(ret), val))
