[ID 20011219.006] patch against IO-1.20.tar.gz
Message ID:

This is a bug report for perl from,
generated with the help of perlbug 1.26 running under perl 5.00503.

[Please enter your report here]

For a number of reasons, I can't run the latest version of Perl right now.
However, many of the CPAN modules are designed to run with Perl 5.6
rather than Perl 5.00503, so I've had to make a few adjustments to
get things to work properly, especially when Perl 5.00503 doesn't have
the socket timeout feature that Perl 5.6 supports.

This change is to IO::Socket::timeout(). Currently, IO::Socket::timeout()
uses the number of array elements in the @_ array to decide whether or
not to set the Socket's timeout. Unfortunately, Net::FTP::_dataconn()
contains logic that looks like this:


where $data and $ftp are both IO::Socket objects. If $ftp->timeout returns
undef, because there is no timeout set, then $data->timeout will see
an @_ array that contains (<socket GLOB>, undef). It then tries to set
${*$sock}{'io_socket_timeout'} to 0 + undef, which triggers a warning.

This modifies the check on timeout's parameter to explicitly look for
undef rather than counting the number of parameters.
