Subject: [PATCH 03/10] searchidxshard: reduce syscalls when writing ->eidx_key
Date: Sat,  7 Nov 2020 10:56:53 +0000
Message-ID: <20201107105700.12586-4-e@80x24.org> (raw)
In-Reply-To: <20201107105700.12586-1-e@80x24.org>

We use ->autoflush(1) on this pipe to ensure the shard workers
see data immediately on print; so this means we have to do our
own buffering for optional data.
