Subject: [PATCH 11/13] SearchIdx,V2Writeable: Update num_highwater on optimized deletes
Date: Wed, 1 Aug 2018 11:43:42 -0500 [thread overview]
Message-ID: <20180801164344.7911-11-ebiederm@xmission.com> (raw)
In-Reply-To: <878t5qkpis.fsf@xmission.com>
When performing an incremental index update with index_sync if a message is seen
to be both added and deleted update the num_highwater mark even though the
message is not otherwise indexed.
This ensures index_sync generates the same msgmap no matter which commit
it stops at during incremental syncs.
