perf test "perf script tests" fails as below in systems
with python 3.6
File "/home/athira/linux/tools/perf/tests/shell/../../scripts/python/parallel-perf.py", line 442
if line := p.stdout.readline():
^
SyntaxError: invalid syntax
--- Cleaning up ---
---- end(-1) ----
92: perf script tests: FAILED!
This happens because ":=" is a new syntax that assigns values
to variables as part of a larger expression. This is introduced
from python 3.8 and hence fails in setup with python 3.6
Address this by splitting the large expression and check the
value in two steps:
Previous line: if line := p.stdout.readline():
Current change:
line = p.stdout.readline()
if line:
With patch
./perf test "perf script tests"
93: perf script tests: Ok
