in reply to how to make close() fail

Seems like a completely unnecessary test to me, but ...

sub TIEHANDLE { bless \$_[1], $_[0] };; sub CLOSE{ 0 };; tie *FH, 'main';; close FH or die 'Aaaaaaaaaaaaarg!';; Aaaaaaaaaaaaarg! at (eval 12) line 1, <STDIN> line 4.

    NFS for example does buffered writes "over the wire", so all the writes apparently work, only for the final flush associated with the close() to fail (e.g. due to filesystem full)

    Dave.

      I know close can fail, but that wasn't my point.

      How complicated can a failed-to-close code path be that you can't test it 'by inspection'?

      And if it is complicated enough to warrant it, it probably indicates poor design.

      More likely this is the triumph of a "100% code coverage" mandate over reason.
