From: Tony Jones Date: Fri, 22 Feb 2019 15:06:17 -0800 Subject: perf script python: Add Python3 support to syscall-counts.py Origin: https://git.kernel.org/linus/1d1b0dbb859d175eb512a9f0e1ca7e44bd0192cd Bug-Debian: https://bugs.debian.org/944641 Support both Python2 and Python3 in the syscall-counts.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/20190222230619.17887-14-tonyj@suse.de Signed-off-by: Seeteena Thoufeek Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/scripts/python/syscall-counts.py | 18 ++++++++++-------- 1 file changed, 10 insertions(+), 8 deletions(-) --- a/tools/perf/scripts/python/syscall-counts.py +++ b/tools/perf/scripts/python/syscall-counts.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 import sys @@ -28,7 +30,7 @@ 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() @@ -51,14 +53,14 @@ 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:\n\n", + print("\nsyscall events:\n") - print "%-40s %10s\n" % ("event", "count"), - print "%-40s %10s\n" % ("----------------------------------------", \ - "-----------"), + print("%-40s %10s" % ("event", "count")) + print("%-40s %10s" % ("----------------------------------------", + "-----------")) - for id, val in sorted(syscalls.iteritems(), key = lambda(k, v): (v, k), \ + for id, val in sorted(syscalls.items(), key = lambda kv: (kv[1], kv[0]), \ reverse = True): - print "%-40s %10d\n" % (syscall_name(id), val), + print("%-40s %10d" % (syscall_name(id), val))
