# 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
|

"""A candidate that has 'extras', indicating additional dependencies.
|

|
||||
Requirements can be for a project with dependencies, something like
|
||||
foo[extra]. The extras don't affect the project/version being installed
|
||||
directly, but indicate that we need additional dependencies. We model that
|
||||
by having an artificial ExtrasCandidate that wraps the "base" candidate.
|
||||
|
||||
The ExtrasCandidate differs from the base in the following ways:
|
||||
|
||||
1. It has a unique name, of the form foo[extra]. This causes the resolver
|
||||
to treat it as a separate node in the dependency graph.
|
||||
2. When we're getting the candidate's dependencies,
|
||||
a) We specify that we want the extra dependencies as well.
|
||||
b) We add a dependency on the base candidate.
|
||||
See below for why this is needed.
|
||||
3. We return None for the underlying InstallRequirement, as the base
|
||||
candidate will provide it, and we don't want to end up with duplicates.
|
||||
|
||||
The dependency on the base candidate is needed so that the resolver can't
|
||||
decide that it should recommend foo[extra1] version 1.0 and foo[extra2]
|
||||
version 2.0. Having those candidates depend on foo=1.0 and foo=2.0
|
||||
respectively forces the resolver to recognise that this is a conflict.
