2025-06-26	perf test: Change all remaining #!/bin/sh to #!/bin/bash	James Clark	1	-1/+1
	There are 43 instances of posix shell tests and 35 instances of bash. To give us a single consistent language for testing in, replace all #!/bin/sh to #!/bin/bash. Common sources that are included in both different shells will now work as expected. And we no longer have to fix up bashisms that appear to work when someone's system has sh symlinked to bash, but don't work on other systems that have both shells installed. Although we could have chosen sh, it's not backwards compatible so it wouldn't be possible to bulk convert without re-writing the existing bash tests. Choosing bash also gives us some nicer features including 'local' variable definitions and regexes in if statements that are already widely used in the tests. It's not expected that there are any users with only sh available due to the large number of bash tests that exist.

2025-05-02	perf test perf-report-hierarchy: Add new test	Arnaldo Carvalho de Melo	1	-0/+43
	Super simple test to check that at least we're not segfaulting when trying to use 'perf report --hierarchy', more subtests should be added to make sure the output is the expected one. This is being merged right before a fix for that that this test detects: # perf test hierarchy 83: perf report --hierarchy : FAILED! # perf test -v hierarchy --- start --- test child forked, pid 102242 perf report --hierarchy Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.025 MB /tmp/perf-test-report.HX0N85TlPq/perf-report-hierarchy-perf.data (6 samples) ] perf: ui/hist.c:603: fmt_free: Assertion `!(!list_empty(&fmt->sort_list))' failed. /home/acme/libexec/perf-core/tests/shell/perf-report-hierarchy.sh: line 34: 102250 Aborted (core dumped) perf report --hierarchy > /dev/null --- Cleaning up --- ---- end(-1) ---- 83: perf report --hierarchy : FAILED! # Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Ian Rogers <irogers@google.com> Cc: James Clark <james.clark@linaro.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Link: https://lore.kernel.org/lkml/20250430180321.736939-1-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
