Subject: [PATCH 01/13] Import.pm: Don't assume {in} and {out} always exist
Date: Wed,  1 Aug 2018 11:43:32 -0500
Message-ID: <20180801164344.7911-1-ebiederm@xmission.com> (raw)
In-Reply-To: <878t5qkpis.fsf@xmission.com>

While working on one of the tests I did:
	my $im = PublicInbox::V2Writable->new($ibx, 1);
	my $im0 = $im->importer();
	$im->add($mime);

Which resulted in a warning of the use of an undefined value from
atfork_child, and the test failing nastily.  Inspection of the code
reveals this can happen anytime gfi_start has not been called.

So just fix atfork_child to skip closing file descriptors that have
not yet been setup.
