# 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.)

"""For neatly implementing static typing in pip.

`mypy` - the static type analysis tool we use - uses the `typing` module, which
provides core functionality fundamental to mypy's functioning.

Generally, `typing` would be imported at runtime and used in that fashion -
it acts as a no-op at runtime and does not have any run-time overhead by
design.

As it turns out, `typing` is not vendorable - it uses separate sources for
Python 2/Python 3. Thus, this codebase can not expect it to be present.
To work around this, mypy allows the typing import to be behind a False-y
optional to prevent it from running at runtime and type-comments can be used
to remove the need for the types to be accessible directly during runtime.

This module provides the False-y guard in a nicely named fashion so that a
curious maintainer can reach here to read this.

In pip, all static-typing related imports should be guarded as follows:

# Special case pip and setuptools to generate versioned wrappers
#
# The issue is that some projects (specifically, pip and setuptools) use
# code in setup.py to create "versioned" entry points - pip2.7 on Python
# 2.7, pip3.3 on Python 3.3, etc. But these entry points are baked into
# the wheel metadata at build time, and so if the wheel is installed with
# a *different* version of Python the entry points will be wrong. The
# correct fix for this is to enhance the metadata to be able to describe
# such versioned entry points, but that won't happen till Metadata 2.0 is
# available.
# In the meantime, projects using versioned entry points will either have
# incorrect versioned entry points, or they will not be able to distribute
# "universal" wheels (i.e., they will need a wheel per Python version).
#
# Because setuptools and pip are bundled with _ensurepip and virtualenv,
# we need to use universal wheels. So, as a stopgap until Metadata 2.0, we
# override the versioned entry points in the wheel and generate the
# correct ones. This code is purely a short-term measure until Metadata 2.0
# is available.
#
# To add the level of hack in this section of code, in order to support
# ensurepip this code will look for an ``ENSUREPIP_OPTIONS`` environment
# variable which will control which version scripts get installed.
#
# ENSUREPIP_OPTIONS=altinstall
# - Only pipX.Y and easy_install-X.Y will be generated and installed

# that this option is technically if ENSUREPIP_OPTIONS is set and is
