perf script python: Add Python3 support to tests/attr.py (2019-02-05 10:31:08 -0300)

----------------------------------------------------------------
perf/urgent fixes:

perf trace:

Arnaldo Carvalho de Melo:

Fix handling of probe:vfs_getname when the probed routine is
inlined in multiple places, fixing the collection of the 'filename'
parameter in open syscalls.

perf test:

Gustavo A. R. Silva:

Fix bitwise operator usage in evsel-tp-sched test, which made tat
test always detect fields as signed.

Jiri Olsa:

Filter out hidden symbols from labels, added in systems where the
annobin plugin is used, such as RHEL8, which, if left in place make
the DWARF unwind 'perf test' to fail on PPC.

Tony Jones:

Fix 'perf_event_attr' tests when building with python3.

perf mem/c2c:

Ravi Bangoria:

Fix perf_mem_events on PowerPC.

tools headers UAPI:

Arnaldo Carvalho de Melo:

Sync linux/in.h copy from the kernel sources, silencing a perf build warning.

Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

----------------------------------------------------------------
Arnaldo Carvalho de Melo (4):
perf clang: Do not use 'return std::move(something)'
tools headers uapi: Sync linux/in.h copy from the kernel sources
perf symbols: Add fallback definitions for GELF_ST_VISIBILITY()
perf trace: Support multiple "vfs_getname" probes

Gustavo A. R. Silva (1):
perf tests evsel-tp-sched: Fix bitwise operator

Jiri Olsa (1):
perf symbols: Filter out hidden symbols from labels

Ravi Bangoria (1):
perf mem/c2c: Fix perf_mem_events to support powerpc

Tony Jones (1):
perf script python: Add Python3 support to tests/attr.py

Test results:

The first ones are container 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.
