#!/usr/bin/env python # # Hi There! # You may be wondering what this giant blob of binary data here is, you might # even be worried that we're up to something nefarious (good for you for being # paranoid!). This is a base85 encoding of a zip file, this zip file contains # an entire copy of pip. # # Pip is a thing that installs packages, pip itself is a package that someone # might want to install, especially if they're looking to run this get-pip.py # script. Pip has a lot of code to deal with the security of installing # packages, various edge cases on various platforms, and other such sort of # "tribal knowledge" that has been encoded in its code base. Because of this # we basically include an entire copy of pip inside this blob. We do this # because the alternatives are attempt to implement a "minipip" that probably # doesn't do things correctly and has weird edge cases, or compress pip itself # down into a single file. # # If you're wondering how this is created, it is using an invoke task located # in tasks/generate.py called "installer". It can be invoked by using # ``invoke generate.installer``. import os.path import pkgutil import shutil import sys import struct import tempfile # Useful for very coarse version differentiation.
