Subject: [PATCH 0/3] make smart-http more robust against bogus server input
Date: Sat, 16 Feb 2013 01:44:55 -0500 [thread overview]
Message-ID: <20130216064455.GA27063@sigill.intra.peff.net> (raw)
For the most part, smart-http just passes data to fetch-pack and
send-pack, which take care of the heavy lifting. However, I did find a
few corner cases around truncated data from the server, one of which can
actually cause a deadlock.
I found these because I was trying to figure out what was going on with
some hung git processes which were in a deadlock like the one described
in patch 3. But having experimented and read the code, I don't think
that it is triggerable from a normal clone, but rather only when you
poke git-remote-curl in the right way. So it may or may not be my
culprit, but these patches do make remote-curl more robust, which is a
good thing.
[1/3]: pkt-line: teach packet_get_line a no-op mode
[2/3]: remote-curl: verify smart-http metadata lines
[3/3]: remote-curl: sanity check ref advertisement from server
