Subject: [PATCH v2 perf-tools-next 0/4] 'perf test' fixes/improvements
Hi,
While evaluating what is needed for having shell tests that test
python functionality conditionally, i.e. so that we don't try to test
the python binding if NO_LIBPYTHON=1 is used, I stumbled into these
problems.
The first patch its more for documenting that strange system()
behaviour and to check if this was something that would have
implications in other 'perf test' cases besides this python one, maybe
somebody will spot the problem, but at least it seems more compact now
using 'python -c inline-python-source'.
v2:
- Don't suppress the python binding test, instead skip it and tell the
reason: the binding isn't available.
- Treat NO_LIBTRACEVENT=1 like NO_LIBPYTHON=1, not suppressing tests, just
skipping them, warn the user on explicit suppression of the library.
- Also reduce a patch description verbosity, as noted by Ian.
- Arnaldo
Arnaldo Carvalho de Melo (4):
perf test python: Robustify the 'perf test python' test case
perf test: Skip the python binding builtin test case with NO_LIBPYTHON=1
perf test: Don't suppress the libtraceevent tests, skip them
perf build: Emit a warning when libtraceevent is explicitely disabled
