Company-centric packaging and testing library
PkgLib: Company-centric Python packaging and testing library
Kindly open-sourced by AHL, this library has the goal of providing a one-stop-shop for Python development houses to get up and running using Python with the minimum of fuss in a Linux development environment.
This library has three main components:
pkglib: a set of packaging tools which extend on a number of the major packaging toolsets in Python - distribute, pip and zc.buildout.
pkglib.testing: a suite of testing utilities to assist with handling services, databases, web drivers and coverage amongst other things, as well as a number of useful py.test plugins.
pkglib.project_template: a PasteScript template for generating packages that integrate with pkglib
Package metadata all sourced from text-file setup.cfg, making it easier to parse package configuration by other releated tools.
Advanced dependency management:
Allows configuration of in-house company packages that are treated differently than third-party libraries.
Backtracking dependency resolver to solve the difficult ‘diamond problem’ of version resolution in complex dependency graphs.
Understands ‘dev’ and ‘release’ version streams, allowing the user to operate in either mode.
Tools to visualise dependency graphs from your current virtualenv.
Improved PyPI interaction, prompts for user credentials and raises correct Unix return codes on error.
Installer search path support to allow eggs to be linked into virtualenvs from shared disk, an important feature when working on shared filesystems in large teams.
Keeps things neat and tidy - cleans out unused packages from your virtualenv’s site-packages directory.
Py.Test integration with python setup.py test:
Configured for sensible defaults for code coverage and quality analysis
Detects when running under Jenkins and Hudson, swapping to file-based reporting and altering tempfile creation.
Command-line tool for managing software ‘platforms’, an abstraction upon single packages when large numbers of interdependant packages are released together.
Checkout and setup packages from in-house repositories by name rather than url.
Numerous powerful setup.py targets:
Combine standalone package docs with automatic API documentation using Sphinx.
Run tests using gcov to allow gathering code coverage of C/C++ extensions.
Synchronise checkouts and libraries with VCS and PyPI
Create Jenkins/Hudson builds.
Generate revision-linked development eggs for build systems.
Generate test-only eggs to capture test code and runtime options.
Deploy package to versioned virtualenvs.
‘Batteries Included’ project template
Utilities with associated Py.Test fixture plugins for:
Profiling code execution, including C/C++ extensions
Managing temp dirs
Creating pkglib enabled packages
Running up servers instances in a port-safe manner, with save, restore and teardown.
Supported servers include jenkins, redis, mongodb, Pyramid and (TODO) a minimal PyPI implementation.
Selenium Webdriver, integrated with the Pyramid server runner plugin.
Page Objects pattern implementation for better structured Selenium tests.
Mocking implementations for databases and other common types.
Full support for git and mercurial.
Python 2.4 -> 3.x support for core distlib functionality.
Upgrade to latest versions of distribute, and bring the project in-line with recent developements in the Python packaging space like distlib.
Add support for wheel binary distribution format.
