Here's an issue I hadn't previously spotted in config/inter/progs.pm --
one that was revealed in the coverage analysis
(http://thenceforward.net/parrot/coverage/configure-build/config-inter-progs-pm.html).
In this package's sub runstep(), there is the following code:
# Find a working version of a program:
# Try each alternative, until one works.
# If none work, then set to null command.
# RT#43173 need config support for a null command.
my $null = 'echo';
my $first_working = sub {
foreach (@_) {
`$_ -h 2>&1`;
return $_ if not $?;
}
return $null;
};
Neither $null nor $first_working is called at any point below this in
the sub or file. It does not appear to be invoked by any configuration
step. And since I don't know what its' for, I can't write a plausible
test for it.
Does anyone know the purpose of this code? svn annotate indicates
jhoblitt and ptc have touched it.
Thank you very much.
