perf tools: Make rm_rf() remove single file (2019-02-20 17:09:28 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf report:
He Kuang:
- Don't shadow inlined symbol with different addr range.
perf script:
Jiri Olsa:
- Allow +- operator to ask for -F to add/remove fields to
the default set, for instance to ask for the removal of the
'cpu' field in tracepoint events, adding 'period' to that
kind of events, etc.
perf test:
Thomas Richter:
- Fix scheduler tracepoint signedness of COMM fields failure of
'evsel-tp-sched' test on s390 and other arches.
Tommi Rantala:
- Skip trace+probe_vfs_getname.sh when 'perf trace' is not built.
perf trace:
Arnaldo Carvalho de Melo:
- Add initial BPF map dumper, initially just for the current, minimal
needs of the augmented_raw_syscalls BPF example used to collect
pointer args payloads that uses BPF maps for pid and syscall filtering,
but will in time have features similar to 'perf stat' --interval-print,
--interval-clear, ways to signal from a BPF event that a specific
map (or range of that map) should be printed, optionally as a
histogram, etc.
General:
Jiri Olsa:
- Add cpu and numa topologies classes for further reuse, fixing some
issues in the process.
- Fixup some warnings and debug levels.
- Make rm_rf() remove single file, not just directories.
Documentation:
Jonas Rabenstein:
- Fix HEADER_CMDLINE description in perf.data documentation.
- Fix documentation of the Flags section in perf.data.

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.
