From: Tony Jones Date: Fri, 22 Feb 2019 15:06:18 -0800 Subject: perf script python: Add Python3 support to syscall-counts-by-pid.py Origin: https://git.kernel.org/linus/de667cce7f4f96b6e22da8fd9c065b961f355080 Bug-Debian: https://bugs.debian.org/944641 Support both Python2 and Python3 in the syscall-counts-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 Link: http://lkml.kernel.org/r/20190222230619.17887-15-tonyj@suse.de Signed-off-by: Seeteena Thoufeek Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/scripts/python/syscall-counts-by-pid.py | 22 +++++++++++---------- 1 file changed, 12 insertions(+), 10 deletions(-) --- a/tools/perf/scripts/python/syscall-counts-by-pid.py +++ b/tools/perf/scripts/python/syscall-counts-by-pid.py @@ -5,6 +5,8 @@ # Displays system-wide system call totals, broken down by syscall. # If a [comm] arg is specified, only syscalls called by [comm] are displayed. +from __future__ import print_function + import os, sys sys.path.append(os.environ['PERF_EXEC_PATH'] + \ @@ -31,7 +33,7 @@ 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_syscall_totals() @@ -55,20 +57,20 @@ def syscalls__sys_enter(event_name, cont def print_syscall_totals(): if for_comm is not None: - print "\nsyscall events for %s:\n\n" % (for_comm), + print("\nsyscall events for %s:\n" % (for_comm)) else: - print "\nsyscall events by comm/pid:\n\n", + print("\nsyscall events by comm/pid:\n") - print "%-40s %10s\n" % ("comm [pid]/syscalls", "count"), - print "%-40s %10s\n" % ("----------------------------------------", \ - "----------"), + print("%-40s %10s" % ("comm [pid]/syscalls", "count")) + print("%-40s %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, val in sorted(syscalls[comm][pid].iteritems(), \ - key = lambda(k, v): (v, k), reverse = True): - print " %-38s %10d\n" % (syscall_name(id), val), + for id, val in sorted(syscalls[comm][pid].items(), \ + key = lambda kv: (kv[1], kv[0]), reverse = True): + print(" %-38s %10d" % (syscall_name(id), val))
