* perf tests daemon: Address shellcheck warningsShirisha G2023-06-131-38/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running shellcheck -S on daemon.sh throws below warnings: Result from shellcheck: # shellcheck -S warning daemon.sh local line_name=`echo "${line}" | awk 'BEGIN { FS = ":" } ; { print $2 }'` ^-------^ SC2155: Declare and assign separately to avoid masking return values. trap "echo 'FAILED: Signal caught'; daemon_exit ${config}; exit 1" SIGINT SIGTERM ^-------^ SC2064: Use single quotes, otherwise this expands now rather than when signalled. count=`ls ${base}/session-test/ | grep perf.data | wc -l` ^-- SC2010: Don't use ls | grep. Use a glob or a for loop with a condition to allow non-alphanumeric filenames. if [ ${size} != "OK" -o ${type} != "OK" ]; then ^-- SC2166: Prefer [ p ] || [ q ] as [ p -o q ] is not well defined. Fixed above warnings by: - declaring and assigning local variables separately - To fix SC2010, instead of using "ls | grep", used glob to allow non-alphanumeric filenames - Used single quotes to prevent expanding. Result from shellcheck after patch changes: $ shellcheck -S warning daemon.sh $ echo $? 0 Signed-off-by: Shirisha G <shirisha@linux.ibm.com> Cc: Disha Goel <disgoel@linux.vnet.ibm.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: John Garry <john.g.garry@oracle.com> Cc: Madhavan Srinivasan <maddy@linux.ibm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Ravi Bangoria <ravi.bangoria@amd.com> Cc: linuxppc-dev@lists.ozlabs.org Link: https://lore.kernel.org/r/20230613164145.50488-5-atrajeev@linux.vnet.ibm.com Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Signed-off-by: Kajol Jain <kjain@linux.ibm.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

| * perf test: Change to use bash for daemon testLeo Yan2021-03-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When executing the daemon test on Arm64 and x86 with Debian (Buster) distro, both skip the test case with the log: # ./perf test -v 76 76: daemon operations : --- start --- test child forked, pid 11687 test daemon list trap: SIGINT: bad trap ./tests/shell/daemon.sh: 173: local: cpu-clock: bad variable name test child finished with -2 ---- end ---- daemon operations: Skip So the error happens for the variable expansion when use local variable in the shell script. Since Debian Buster uses dash but not bash as non-interactive shell, when execute the daemon testing, it hits a known issue for dash which was reported [1]. To resolve this issue, one option is to add double quotes for all local variables assignment, so need to change the code from: local line=`perf daemon --config ${config} -x: | head -2 | tail -1` ... to: local line="`perf daemon --config ${config} -x: | head -2 | tail -1`" But the testing script has bunch of local variables, this leads to big changes for whole script. On the other hand, the testing script asks to use the "local" feature which is bash-specific, so this patch explicitly uses "#!/bin/bash" to ensure running the script with bash. After: # ./perf test -v 76 76: daemon operations : --- start --- test child forked, pid 11329 test daemon list test daemon reconfig test daemon stop test daemon signal signal 12 sent to session 'test [11596]' signal 12 sent to session 'test [11596]' test daemon ping test daemon lock test child finished with 0 ---- end ---- daemon operations: Ok [1] https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097 Fixes: 2291bb915b55 ("perf tests: Add daemon 'list' command test") Signed-off-by: Leo Yan <leo.yan@linaro.org> Acked-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20210320104554.529213-1-leo.yan@linaro.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
