perf tests lib probe: Fix shellcheck warning about about missing shebang

2023-08-03T20:01:26+00:00

Running shellcheck on probe.sh throws below warning: In lib/probe.sh line 1: ^-- SC2148 (error): Tips depend on target shell and yours is unknown. Add a shebang or a 'shell' directive. Fixed the warnings by adding shell directive.

perf tests shell: Skip trace+probe_vfs_getname.sh if built without trace support

2019-02-15T16:42:26+00:00

If perf was built without trace support, the trace+probe_vfs_getname.sh 'perf test' entry fails: # perf trace -h perf: 'trace' is not a perf-command. See 'perf --help' # perf test 64 64: Check open filename arg using perf trace + vfs_getname: FAILED! Check trace support, so that we'll skip the test in that case: # perf test 64 64: Check open filename arg using perf trace + vfs_getname: Skip Signed-off-by: Tommi Rantala Cc: Alexander Shishkin Cc: Hendrik Brueckner Cc: Jiri Olsa Cc: Kim Phillips Cc: Michael Petlan Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20190215134253.11454-1-tt.rantala@gmail.com Signed-off-by: Arnaldo Carvalho de Melo

perf test shell: Replace '|&' with '2>&1 |' to work with more shells

2017-08-16T19:23:26+00:00

Since we do not specify bash (and/or zsh) as a requirement, use the standard error redirection that is more widely supported. Signed-off-by: Kim Phillips Link: http://lkml.kernel.org/n/tip-ji5mhn3iilgch3eaay6csr6z@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf test shell: Check if 'perf probe' is available, skip tests if not

2017-08-15T13:54:25+00:00

Add a library function that checks if 'perf probe' is built into the tool being tested, skipping tests that need it. Testing it on a system after removing the library needed to build 'probe' as a perf subcommand: # perf test ping vfs_getname 59: Use vfs_getname probe to get syscall args filenames : Skip 60: probe libc's inet_pton & backtrace it with ping : Skip 61: Check open filename arg using perf trace + vfs_getname: Skip 62: Add vfs_getname probe to get syscall args filenames : Skip # perf probe perf: 'probe' is not a perf-command. See 'perf --help'. # Now reinstalling elfutils-libelf-devel on this Fedora 26 system to rebuild perf and then retest this: # perf test ping vfs_getname 60: Use vfs_getname probe to get syscall args filenames : Ok 61: probe libc's inet_pton & backtrace it with ping : Ok 62: Check open filename arg using perf trace + vfs_getname: Ok 63: Add vfs_getname probe to get syscall args filenames : Ok # Reported-by: Kim Phillips Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Michael Petlan Cc: Namhyung Kim Cc: Thomas Richter Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-ctdck2gzsskqhjzu3ebb62zm@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo
