# 2016-06-17 barry@debian.org: urllib3 1.14 added optional support for 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.

#
# The obvious thing that affects output is the show_stdout=
# kwarg. show_stdout=True means, let the subprocess write directly to our
# stdout. Even though it is nominally the default, it is almost never used
# inside pip (and should not be used in new code without a very good
# reason); as of 2016-02-22 it is only used in a few places inside the VCS
# wrapper code. Ideally we should get rid of it entirely, because it
# creates a lot of complexity here for a rarely used feature.
#
# Most places in pip set show_stdout=False. What this means is:
# - We connect the child stdout to a pipe, which we read.
# - By default, we hide the output but show a spinner -- unless the
# subprocess exits with an error, in which case we show the output.
# - If the --verbose option was passed (= loglevel is DEBUG), then we show
# the output unconditionally. (But in this case we don't want to show
# the output a second time if it turns out that there was an error.)
#
# stderr is always merged with stdout (even if show_stdout=True).
