1047020 - Peep Install Occasionally Fails

Status: RESOLVED FIXED

(Socorro :: Infra, task)

Description

[Trevor Bramwell :bramwelt]

If you forget on occasion to use a python2.6 virtualenv, pip will grab a wheel from pypi instead of the tarball. This is not anything in our control, and can be fixed by adding the hashes for pep8 and pyflakes wheels.

Each of these should still be independently verified.

pep8

wheel: https://pypi.python.org/packages/3.3/p/pep8/pep8-1.5.7-py2.py3-none-any.whl#md5=e64cf25ebf3ee49b1ab18ee7fb225d41
tarball: https://pypi.python.org/packages/source/p/pep8/pep8-1.5.7.tar.gz#md5=f6adbdd69365ecca20513c709f9b7c93

pyflakes

wheel: https://pypi.python.org/packages/3.3/p/pyflakes/pyflakes-0.8.1-py2.py3-none-any.whl#md5=a9810b19e048e77ba1ce5364a77aa32e
tarball: https://pypi.python.org/packages/source/p/pyflakes/pyflakes-0.8.1.tar.gz#md5=905fe91ad14b912807e8fdc2ac2e2c23

I'm still a noob when it comes to wheels but it looks like those wheels are only made for python 3. So doing `pip install pep8|pyflakes` in python 2(.6) should only get us the tranditional tarballs.

The wheel for pep8 on pypi is not specific to python3. It was build as a universal wheel, meaning it works for both python 2 and 3.

The wheel[1] docs provide a fuller explanation of wheels and the "universal=1" option.

Pip's documentation[2] on why this happens is also enlightening: "Pip prefers Wheels where they are available. To disable this, use the –no-use-wheel flag for pip install."

A ha! I think I finally get it. You mean that even in python 2, you can sometimes get the wheel and that's why you need two shas. r+

Add pep8, pyflakes wheel hash to requirements

Also pins pep8 at 1.5.7.

PyPI will send back wheels or tarballs, and there is no way to know
which will come back when installing a package through pip.
