Pull tracing fixes from Steven Rostedt: "Masami had a couple more fixes to the synthetic events. One was a proper error return value, and the other is for the self tests" * tag 'trace-v4.19-rc8-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: selftests/ftrace: Fix synthetic event test to delete event correctly tracing: Return -ENOENT if there is no target synthetic event

selftests/ftrace: Fix synthetic event test to delete event correctly

2018-10-28T19:14:55Z

Fix the synthetic event test case to remove event correctly. If redirecting command to synthetic_event file without append mode, it cleans up all existing events and execute (parse) the command. This means "delete event" always fails to find the target event. Since previous synthetic event has a bug which doesn't return -ENOENT even if it fails to find the deleting event, this test passed. But fixing that bug, this test fails because this test itself has a bug. This fixes that bug by trying to delete event right after adding an event, and use append mode redirection ('>>') instead of normal redirection ('>').

selftests/ftrace: Strip escape sequences for log file

Strip escape sequences from the stream to the ftracetest summary log file. Note that all test-case results are dumped raw in each file. Signed-off-by: Masami Hiramatsu Acked-by: Steven Rostedt (VMware) Signed-off-by: Shuah Khan (Samsung OSG)

selftests/ftrace: Use colored output when available

2018-10-24T20:49:37Z

If test is being directly executed (with stdout opened on the terminal) and the terminal capabilities indicate enough colors, then use the existing scheme of green, red, and blue to show when tests pass, fail or end in a different way. When running the tests redirecting the stdout, for instance, to a file, then colors are not shown, thus producing a more readable output.

selftests/ftrace: Add color to the PASS / FAIL results

2018-10-24T20:49:37Z

Now that ftracetest has over 80 tests, it is difficult to simply scroll up the console window to find the failed tests when it reports just two tests have failed. In order to make this stand out better, have the color of the word "PASS" be green, "FAIL" and "XFAIL" be red, and all other results be blue. This helps tremendously in quickly spotting the failed tests by just scrolling up the console window. Signed-off-by: Steven Rostedt (VMware) Signed-off-by: Shuah Khan (Samsung OSG)
