From: Tony Jones <tonyj@suse.de>
Date: Wed, 23 Jan 2019 16:52:29 -0800
Subject: perf script python: Add Python3 support to tests/attr.py
Git-commit: 35ea7e4bbb89ecd32057f5f6a2a8feb0d7224e51
Patch-mainline: v5.1-rc1
References: bsc#1082197
X-Info: adjust context, no 741dad88dde2 b24413180f56 3440fe2790aa 1f41873c2282 04c31bcf86c4 19508c048a2f

Support both Python 2 and Python 3 in tests/attr.py

The use of "except as" syntax implies the minimum supported Python2 version is
now v2.6

Committer testing:

$ make -C tools/perf PYTHON3=python install-bin

Before:

# perf test attr
  16: Setup struct perf_event_attr                          : FAILED!
  48: Synthesize attr update                                : Ok
  [root@quaco ~]# perf test -v attr
  16: Setup struct perf_event_attr                          :
  --- start ---
  test child forked, pid 3121
    File "/home/acme/libexec/perf-core/tests/attr.py", line 324
      except Unsup, obj:
                ^
  SyntaxError: invalid syntax

  ---- end ----
  Setup struct perf_event_attr: FAILED!

  ---- end ----
  Synthesize attr update: Ok

After:

# perf test attr
  16: Setup struct perf_event_attr                          : Ok
  48: Synthesize attr update                                : Ok
