Subject: [GIT PULL 0/9] perf/urgent fixes
Date: Tue, 12 Sep 2017 16:24:29 -0300
Message-ID: <> (raw)

Hi Ingo,

	So here it is the fixes in perf-core-for-mingo-4.14-20170912, as
requested, plus one last minute fix from Milian Wolff that helps with
using perf as an AppImage[1].

- Arnaldo

  perf stat: Wait for the correct child (2017-09-12 12:49:13 -0300)

perf/urgent fixes:

- Fix TUI progress bar when delta from new total from that of the
  previous update is greater than the progress "step" (screen width
  progress bar block))  (Jiri Olsa)

- Make tools/lib/api make DEBUG=1 build use -D_FORTIFY_SOURCE=2 not
  to cripple debuginfo, just like tools/perf/ does (Jiri Olsa)

- Avoid leaking the '' file to workloads started from the
  'perf record' command line by using the O_CLOEXEC open flag (Jiri Olsa)

- Fix building when libunwind's 'unwind.h' file is present in the
  include path, clashing with tools/perf/util/unwind.h (Milian Wolff)

- Check per .perfconfig section entry flag, not just per section (Taeung Song)

- Support running perf binaries with a dash in their name, needed to
  run perf as an AppImage (Milian Wolff)

- Wait for the right child by using waitpid() when running workloads
  from 'perf stat', also to fix using perf as an AppImage (Milian Wolff)

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

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

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.

The 'perf test'  also runs shell scripts exercising the tools, checking
if they affect the system in certain ways, like setting up kprobes and
uprobes, request callchains for well known programs and check that they
are the expected ones, see if 'perf trace' beautifies system call
arguments correctly, etc.

Additionally, a new set of tests, script based, runs the tools in a live system,
setting probes in place that then gets used by 'perf trace', with its output
compared against expected results.

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.
