Subject: [PATCH 2/3] http: ensure errors are printable before PSGI env
Date: Sun, 6 Mar 2016 02:09:21 +0000 [thread overview]
Message-ID: <1457230162-10960-3-git-send-email-e@80x24.org> (raw)
In-Reply-To: <1457230162-10960-1-git-send-email-e@80x24.org>
We cannot rely on a client socket having a PSGI env before headers
are fully-parsed as we seek to avoid storing hashes for idle
clients. Sso print errors to the psgi.errors value which belongs to
the httpd listener, instead.
