From: Daira Hopwood Date: Fri, 17 Apr 2015 20:39:01 +0000 (+0100) Subject: Unconditionally use HTTPConnectionPool, and depend on a Twisted that provides it. X-Git-Url: https://git.rkrishnan.org/pf/statistics?a=commitdiff_plain;h=fb4d6784ef7bff4fa9908353e7e10b26f2cc391a;p=tahoe-lafs%2Ftahoe-lafs.git Unconditionally use HTTPConnectionPool, and depend on a Twisted that provides it. (The dependency change only affects Windows.)
