[ Upstream commit 82f4f3e69c5c29bce940dd87a2c0f16c51d48d17 ]

Add a testcase for checking snapshot and tracing_on
relationship. This ensures that the snapshotting doesn't
affect current tracing on/off settings.

ftracetest: Add POSIX.3 standard and XFAIL result codes 2014-10-03T20:44:02+00:00 Masami Hiramatsu masami.hiramatsu.pt@hitachi.com 2014-09-29T12:02:11+00:00 915de2adb584acea89f3f654a6c9b329f682100f Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/ UNTESTED/UNSUPPORTED) as result codes. These are used for the results that test case is expected to fail or unsupported feature (by config). To return these result code, this introduces exit_unresolved, exit_untested, exit_unsupported and exit_xfail functions, which use real-time signals to notify the result code to ftracetest. This also set "errexit" option for the testcases, so that the tests don't need to exit explicitly. Note that if the test returns UNRESOLVED/UNSUPPORTED/FAIL, its test log including executed commands is shown on console and main logfile as below. ------ # ./ftracetest samples/ === Ftrace unit tests === [1] failure-case example [FAIL] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/fail.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/fail.tc ++ cat non-exist-file cat: non-exist-file: No such file or directory [2] pass-case example [PASS] [3] unresolved-case example [UNRESOLVED] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unresolved.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unresolved.tc ++ trap exit_unresolved INT ++ kill -INT 29324 +++ exit_unresolved +++ kill -s 38 29265 +++ exit 0 [4] unsupported-case example [UNSUPPORTED] execute: /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unsupported.tc + . /home/fedora/ksrc/linux-3/tools/testing/selftests/ftrace/samples/unsupported.tc ++ exit_unsupported ++ kill -s 40 29265 ++ exit 0 [5] untested-case example [UNTESTED] [6] xfail-case example [XFAIL] # of passed: 1 # of failed: 1 # of unresolved: 1 # of untested: 1 # of unsupported: 1 # of xfailed: 1 # of undefined(test bug): 0 ------ Link: http://lkml.kernel.org/p/20140929120211.30203.99510.stgit@kbuild-f20.novalocal Acked-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> 
Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/
UNTESTED/UNSUPPORTED) as result codes. These are used for the
results that test case is expected to fail or unsupported
feature (by config).

To return these result code, this introduces exit_unresolved,
exit_untested, exit_unsupported and exit_xfail functions,
which use real-time signals to notify the result code to
ftracetest.

This also set "errexit" option for the testcases, so that
the tests don't need to exit explicitly.

Note that if the test returns UNRESOLVED/UNSUPPORTED/FAIL,
its test log including executed commands is shown on console
and main logfile as below.
