perf test shell: Replace '|&' with '2>&1 |' to work with more shells (2017-08-16 16:23:26 -0300)
----------------------------------------------------------------
perf core improvements and fixes:
New features:
- Support exporting Intel PT data to sqlite3 with python perf scripts,
this is in addition to the postgresql support that was already there (Adrian Hunter)
Infrastructure:
- Handle perf tool builds with less features in perf shell tests, such
as those with NO_LIBDWARF=1 or even without 'perf probe' (Arnaldo Carvalho de Melo)
- Replace '|&' with '2>&1 |' to work with more shells in the just
introduced perf test shell harness (Kim Phillips)
Architecture related fixes:
- Fix endianness problem when loading parameters in the BPF prologue
generated by perf, noticed using 'perf test BPF' in s390x systems (Wang Nan, Thomas Richter)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
Adrian Hunter (5):
perf scripts python: Fix missing call_path_id in export-to-postgresql script
perf scripts python: Fix query in call-graph-from-postgresql.py
perf script python: Add support for exporting to sqlite3
perf script python: Rename call-graph-from-postgresql.py to call-graph-from-sql.py
perf script python: Add support for sqlite3 to call-graph-from-sql.py
Arnaldo Carvalho de Melo (3):
perf tests shell: Remove duplicate skip_if_no_debuginfo() function
perf test shell: Check if 'perf probe' is available, skip tests if not
perf test shell vfs_getname: Skip for tools built with NO_LIBDWARF=1
Kim Phillips (1):
perf test shell: Replace '|&' with '2>&1 |' to work with more shells

perf bpf: Fix endianness problem when loading parameters in prologue

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
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.
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.
