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
