Subject: [PATCH 13/13] V2Writeable.pm: In unindex_oid delete the message from msgmap
Date: Wed,  1 Aug 2018 11:43:44 -0500
Message-ID: <20180801164344.7911-13-ebiederm@xmission.com> (raw)
In-Reply-To: <878t5qkpis.fsf@xmission.com>

Now that we track the num highwater mark it is safe to remove messages
from msgmap that have been previously allocated.  Removing even the
highest numbered article will no longer cause new message numbers to
move backwards.
