2013-01-24	perf tests: Check python path on attr and binding test	Namhyung Kim	1	-2/+2
	Current perf test code tries to execute python version 2 in order to test attributes on perf_event_open syscall. However it's not default python version anymore a system can have python v3 only or v2 with a different name (e.g. python2). So if there's no such python interpreter with the name 'python', the test would fail like this (yes, it's happened on my new archlinux laptop :). 13: struct perf_event_attr setup :sh: python: command not found FAILED! As we can pass name of the python interpreter on make, use it for the attr test also.

2013-01-24	perf test: Check for linking problems in the python binding	Arnaldo Carvalho de Melo	1	-0/+23
	It just will add the O= builddir to PYTHONPATH and try to 'use perf', which will, in verbose mode show the python backtrace with the missing symbols, such as in the problem fixed in the patch after this one: # perf test -v 15 15: Try 'use perf' in python, checking link problems : --- start --- Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: /home/acme/git/build/perf//python/perf.so: undefined symbol: test_attr__enabled ---- end ---- Try 'use perf' in python, checking link problems: FAILED! # Loooong overdue, done.
