From: Aditya Gupta <redacted> ${$1} gives bad substitution error on sh, bash, and zsh. This seems like a typo, and this patch modifies it to $1, since that is what it's usage looks like from wherever `check_exec_0` is called.Nicely spotted! Please add the people that last touched the problem to the cc list, specially when it fixes a bug. Thanks for adding a Fixes tag, that helps the stable@kernel.org guys to get this propagated to supported kernel releases. I've added the test author to the CC list in this message. thanks! - Arnaldoquoted
This issue due to ${$1} caused all function calls to give error in `find_str_or_fail` line, and so no test runs completely. But 'perf test "perf script task-analyzer tests"' wrongly reports that tests passed with the status OK, which is wrong considering the tests didn't even run completely Fixes: e8478b84d6ba ("perf test: add new task-analyzer tests") Signed-off-by: Athira Rajeev <redacted> Signed-off-by: Kajol Jain <redacted> Signed-off-by: Aditya Gupta <redacted> ---
I'm seeing a different error even after this fix. Can you please take a look? Thanks, Namhyung $ sudo ./perf test -v task 114: perf script task-analyzer tests :
