Subject: Re: [tip:perf/core] perf test shell: Install shell tests

Hi Arnaldo!

Maybe this would be the right time to incorporate the shell-based
perftool-testsuite [1] into perf-test, wouldn't it?

It already contains bunch of shell-based perf tests that cover
25+ RH bugs...

A little problem might be different design, since the testsuite
has multiple levels of hierarchy of sub-sub-sub-tests, like:

...
-- [ PASS ] -- perf_probe :: test_probe_syntax :: custom named probe :: add
-- [ PASS ] -- perf_probe :: test_probe_syntax :: custom named probe :: list
-- [ PASS ] -- perf_probe :: test_probe_syntax :: custom named probe :: use
-- [ PASS ] -- perf_probe :: test_probe_syntax :: various syntax forms :: vfs_read@...read_write.c
-- [ PASS ] -- perf_probe :: test_probe_syntax :: various syntax forms :: vfs_read:11@...read_write.c
-- [ PASS ] -- perf_probe :: test_probe_syntax :: various syntax forms :: vfs_read@...read_write.c:11
-- [ PASS ] -- perf_probe :: test_probe_syntax :: various syntax forms :: vfs_read%return
-- [ PASS ] -- perf_probe :: test_probe_syntax :: various syntax forms :: test.c:29
-- [ PASS ] -- perf_probe :: test_probe_syntax :: various syntax forms :: func%return $retval
## [ PASS ] ## perf_probe :: test_probe_syntax SUMMARY
-- [ PASS ] -- perf_probe :: test_sdt :: adding SDT tracepoints as probes
-- [ PASS ] -- perf_probe :: test_sdt :: listing added probes
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf stat (N = 13)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf stat (N = 128)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf stat (N = 241)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf record (N = 37)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf report (N = 37)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf script (N = 37)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf record (N = 97)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf report (N = 97)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf script (N = 97)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf record (N = 237)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf report (N = 237)
-- [ PASS ] -- perf_probe :: test_sdt :: using probes :: perf script (N = 237)
## [ PASS ] ## perf_probe :: test_sdt SUMMARY
...

... which does not exactly match how perf-test is structured, however,
I think that the multi-level structure of the testsuite is important
for keeping some order in it...

What do you think?

Cheers,
Michael
