freeze-requirements2 0.5.3.1

freeze-requirements

freeze-requirements2 is a fork of https://github.com/flupke/freeze-requirements which is just missing one commit for newver versions of pip. Nothing more nothing less.

A script to help creating and maintaining frozen requirements for pip, inspired by this Mozilla dev team blog post.

Frozen requirements contain the packages you specified, plus all their dependencies, with pinned versions.

For example if you have requirements.txt containing this:

pyramid
sqlalchemy

The frozen version would be:

# This file has been automatically generated, DO NOT EDIT!

# Frozen requirements for "requirements.txt"

pastedeploy==1.5.2
pyramid==1.5.1
repoze.lru==0.6
setuptools==5.5.1
sqlalchemy==0.9.7
translationstring==1.1
venusian==1.0
webob==1.4
zope.deprecation==4.1.1
zope.interface==4.1.1

Then you can use the frozen requirements in your deployment scripts with pip install -r requirements-frozen.txt --no-deps, and enjoy consistent deployments even if some packages are updated on pypi.

freeze-requirements can also put the downloaded source packages in a pypi-like directory structure on your web server, so you can speed up your deployments with pip install -r requirements-frozen.txt --index-url http://mywebserver.com/pypi-mirror, and also build wheels to speed up deployments even more.

$ pip install freeze-requirements

$ ./setup.py install

$ freeze-requirements freeze --separate-requirements requirements.txt requirements2.txt

$ freeze-requirements freeze --merged-requirements requirements-merged.txt requirements.txt requirements2.txt

$ freeze-requirements freeze --cache-dependencies requirements.txt

$ freeze-requirements freeze --output-dir /path/to/my/pypi --build-wheels requirements.txt
