Thanks for reporting. The relevant code is
die __("--dump-aliases incompatible with other options\n")
if !$help and $dump_aliases and @ARGV;
test_must_fail prints the "command not found" message if and only if
the status code was 127. I would have expected it to be 1 or 128
here.
"man perlfunc" says
If the exception is outside of all enclosing "eval"s, then
the uncaught exception prints LIST to "STDERR" and exits with a
non-zero value. If you need to exit the process with a specific
exit code, see "exit".
That doesn't tell me what the status code will be. Peeking at the source,
I find
int exitstatus;
if (errno & 255)
STATUS_UNIX_SET(errno);
else {
exitstatus = STATUS_UNIX >> 8;
if (exitstatus & 255)
STATUS_UNIX_SET(exitstatus);
else
STATUS_UNIX_SET(255);
}
which seems risky (there are many functions that could set errno, so
this is prone to spooky action at a distance if any caller forgets to
set it explicitly). Looking for errno values that could be 127 in
glibc and linux using "git grep --cached -e '#.*define.*E.*127'", I
find
linux:arch/alpha/include/uapi/asm/errno.h:#define ERESTART127
linux:arch/mips/include/uapi/asm/errno.h:#define ENETDOWN 127
linux:arch/sparc/include/uapi/asm/errno.h:#define ECANCELED 127
linux:include/uapi/asm-generic/errno.h:#defineEKEYEXPIRED 127
so that doesn't look likely to be the cause.
Next step is to ssh into porterboxes and get the output of
perl -e 'die "testing"'; echo $?"
