Hi,
We've been facing a strange issue. Clients use X11 forwarding via SSH on HP server and sometimes the same DISPLAY is assigned to two (maybe more) sessions. As a result, some users can't open their applications, and some have their windows redirected to somebody else.
It looks as if sshd... (1 Reply)

perl::critic::policy::subroutines::requirefinalreturn
Perl::Critic::Policy::Subroutines::RequireFinalReturn(3)User Contributed Perl DocumentatioPerl::Critic::Policy::Subroutines::RequireFinalReturn(3)
NAME
Perl::Critic::Policy::Subroutines::RequireFinalReturn - End every path through a subroutine with an explicit "return" statement.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Require all subroutines to terminate explicitly with one of the following: "return", "carp", "croak", "die", "exec", "exit", "goto", or
"throw".
Subroutines without explicit return statements at their ends can be confusing. It can be challenging to deduce what the return value will
be.
Furthermore, if the programmer did not mean for there to be a significant return value, and omits a return statement, some of the
subroutine's inner data can leak to the outside. Consider this case:
package Password;
# every time the user guesses the password wrong, its value
# is rotated by one character
my $password;
sub set_password {
$password = shift;
}
sub check_password {
my $guess = shift;
if ($guess eq $password) {
unlock_secrets();
} else {
$password = (substr $password, 1).(substr $password, 0, 1);
}
}
1;
In this case, the last statement in check_password() is the assignment. The result of that assignment is the implicit return value, so a
wrong guess returns the right password! Adding a "return;" at the end of that subroutine solves the problem.
The only exception allowed is an empty subroutine.
Be careful when fixing problems identified by this Policy; don't blindly put a "return;" statement at the end of every subroutine.
CONFIGURATION
If you've created your own terminal functions that behave like "die" or "exit", then you can configure Perl::Critic to recognize those
functions as well. Just put something like this in your .perlcriticrc:
[Subroutines::RequireFinalReturn]
terminal_funcs = quit abort bailout
BUGS
We do not look for returns inside ternary operators. That construction is too complicated to analyze right now. Besides, a better form is
the return outside of the ternary like this: "return foo ? 1 : bar ? 2 : 3"
