Subject: [PATCH 40/57] ds|nntp: use CORE::close on socket
Date: Mon, 24 Jun 2019 02:52:41 +0000 [thread overview]
Message-ID: <20190624025258.25592-41-e@80x24.org> (raw)
In-Reply-To: <20190624025258.25592-1-e@80x24.org>
IO::Socket::SSL will try to re-bless back to the original class
on TLS negotiation failure. Unfortunately, the original class
is 'GLOB', and re-blessing to 'GLOB' takes away all the IO::Handle
methods, because Filehandle/IO are a special case in Perl5.
Anyways, since we already use syswrite() and sysread() as functions
on our socket, we might as well use CORE::close(), as well (and
it plays nicely with tied classes).
