# 2016-06-17 barry@debian.org: urllib3 1.14 added optional support for socks,
# but if invoked (i.e. imported), it will issue a warning to stderr if socks
# isn't available. requests unconditionally imports urllib3's socks contrib
# module, triggering this warning. The warning breaks DEP-8 tests (because of
# the stderr output) and is just plain annoying in normal usage. I don't want
# to add socks as yet another dependency for pip, nor do I want to allow-stder
# in the DEP-8 tests, so just suppress the warning. pdb tells me this has to
# be done before the import of pip.vcs.
