Subject: [PATCH 10/12] receive-pack: relay connectivity errors to sideband
Date: Fri, 15 Jul 2016 06:36:14 -0400 [thread overview]
Message-ID: <20160715103614.GJ19271@sigill.intra.peff.net> (raw)
In-Reply-To: <20160715102506.GA23164@sigill.intra.peff.net>
If the connectivity check encounters a problem when
receiving a push, the error output goes to receive-pack's
stderr, whose destination depends on the protocol used
(ssh tends to send it to the user, though without a "remote"
prefix; http will generally eat it in the server's error
log).
The information should consistently go back to the user, as
there is a reasonable chance their client is buggy and
generating a bad pack.
We can do so by muxing it over the sideband as we do with
other sub-process stderr.
