perf tools: Use python-config --includes rather than --cflags (2018-07-11 09:48:31 -0400)
----------------------------------------------------------------
perf/urgent fixes:
python interface:
- Make 'perf script -g python' generate scripts that are compatible
with both python 2 and 3 (Jeremy Cline)
- Fix python dictionary reference counting (Janne Huttunen)
- Add python3 support for various python scripts (Jeremy Cline)
- Use python-config --includes rather than --cflags, fixing the build
on Fedora, where the python 3.7 started adding -flto to what
perf stat:
- Remove needless extra header line in --interval_clear (Jiri Olsa)
python-config --cflags generate, breaking the perf build (Jeremy Cline)
Build:
- Fix compilation errors on gcc8 (Jiri Olsa)
perf llvm-utils:
- Remove bashism from kernel include fetch script (Kim Phillips)
perf test: (Kim Phillips)
- Replace '|&' with '2>&1 |' to work with more shells
- Make perf's inet_pton test more portable
- Prevent temporary editor files from being considered test scripts

Test results:
The first ones are container (docker) based builds of tools/perf with
and without libelf support. Where clang is available, it is also used
to build perf with/without libelf, and building with LIBCLANGLLVM=1
(built-in clang) with gcc and clang when clang and its devel libraries
are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
