A library to help package Odoo addons with setuptools

Project description

License: LGPL-3 https://badge.fury.io/py/setuptools-odoo.svg https://travis-ci.org/acsone/setuptools-odoo.svg?branch=master https://coveralls.io/repos/acsone/setuptools-odoo/badge.svg?branch=master&service=github

setuptools-odoo is a library to help packaging Odoo addons with setuptools. It mainly populate the usual setup.py keywords from the Odoo manifest files.

Together with odoo-autodiscover, it constitutes the foundation to package and distribute Odoo addons using standard python infrastructure (ie setuptools, pip, wheel, and pypi).

Packaging a single addon

To be packaged with this library, the addon source code must have the following structure (assuming the addon is named <addon_name>):

setup.py
odoo_addons/
odoo_addons/__init__.py
odoo_addons/<addon_name>/
odoo_addons/<addon_name>/__openerp__.py
odoo_addons/<addon_name>/...

where odoo_addons/__init__.py is a standard python namespace package declaration __init__.py:

__import__('pkg_resources').declare_namespace(__name__)

and where setup.py has the following content:

import setuptools

setuptools.setup(
    setup_requires=['setuptools-odoo'],
    odoo_addon=True,
)

The usual setup() keyword arguments are computed automatically from the Odoo manifest file (__openerp__.py) and contain:

  • name: the package name, odoo-addon-<addon_name>

  • version: the version key from the manifest

  • description: the summary key from the manifest if it exists otherwise the name key from the manifest

  • long_description: the content of the README.rst file if it exists, otherwise the description key from the manifest

  • url: the website key from the manifest

  • licence: the license key from the manifest

  • packages: autodetected packages

  • namespace_packages: ['odoo_addons']

  • zip_safe: False

  • include_package_data: True

  • install_requires: dependencies to Odoo, other addons (except official odoo addons, which are brought by the Odoo dependency) and python libraries.

Then, the addon can be deployed and packaged with usual setup.py or pip commands such as:

python setup.py install
python setup.py develop
python setup.py bdist_wheel
pip install .
pip install -e .
pip install odoo-addon-<addon name>

To run Odoo so it automatically discovers addons installed with this method, start Odoo using the odoo-server-autodiscover or odoo-autodiscover.py scripts provided in the odoo-autodiscover package.

It is of course highly recommanded to run all this inside a virtualenv.

Packaging multiple addons

Addons that are intended to be reused or depended upon by other addons MUST be packaged individually. When preparing a project for a specific customer, it is common to prepare a collection of addons that are not intended to be depended upon by addons outside of the project. setuptools-odoo provides tools to help you do that.

To be packaged with this library, your project must be structured according to the following structure:

setup.py
odoo_addons/
odoo_addons/__init__.py
odoo_addons/<addon1_name>/
odoo_addons/<addon1_name>/__openerp__.py
odoo_addons/<addon1_name>/...
odoo_addons/<addon2_name>/
odoo_addons/<addon2_name>/__openerp__.py
odoo_addons/<addon2_name>/...

where setup.py has the following content:

import setuptools

setuptools.setup(
    name='<your project package name>',
    version='<your version>',
    # ...any other setup() keyword
    setup_requires=['setuptools-odoo'],
    odoo_addons=True,
)

The following setup() keyword arguments are computed automatically from the Odoo manifest files (__openerp__.py) and contain:

  • packages: autodetected packages

  • namespace_packages: ['odoo_addons']

  • zip_safe: False

  • include_package_data: True

  • install_requires: dependencies on Odoo, any depending addon not found in the addons directory, and external python dependencies.

Controlling setuptools-odoo behaviour

It is possible to use a dictionary instead of True for the odoo_addon and odoo_addons keywords, in order to control their behaviour.

The following keys are supported:

  • depends_override, used to precisely control odoo addons dependencies. Its value must be a dictionary mapping addon names to a package requirement string.

  • external_dependencies_override, used to precisely control python external dependencies. Its value must be a dictionary with one python key, with value a dictionary mapping python external dependencies to python package requirement strings.

  • odoo_version_override, used to specify which Odoo series to use (8.0, 9.0, etc) in case an addon version does not start with the Odoo series number. Use this only as a last resort, if you have no way to correct the addon version in its manifest.

For instance, if your module requires at least version 8.0.3.2.0 of the connector addon, as well as at least version 0.5.5 of py-Asterisk, your setup.py would look like this:

import setuptools

setuptools.setup(
    setup_requires=['setuptools-odoo'],
    odoo_addon={
        'depends_override': {
            'connector': 'odoo-addon-connector>=8.0.3.2.0,<9.0a',
        },
        'external_dependencies_override': {
            'python': {
                'Asterisk': 'py-Asterisk>=0.5.5',
            },
        },
    },
)

setuptools-odoo-make-default helper script

Since reusable addons are generally not structured using the namespace package but instead collected in a directory with each subdirectory containing an addon, this package provides the setuptools-odoo-make-default script which creates a default setup.py for each addon according to the following structure:

setup/
setup/addon1/
setup/addon1/setup.py
setup/addon1/odoo_addons/
setup/addon1/odoo_addons/__init__.py
setup/addon1/odoo_addons/<addon1_name> -> ../../../<addon1_name>
setup/addon2/setup.py
setup/addon2/odoo_addons/
setup/addon2/odoo_addons/__init__.py
setup/addon2/odoo_addons/<addon2_name> -> ../../../<addon2_name>
<addon1_name>/
<addon1_name>/__openerp__.py
<addon1_name>/...
<addon2_name>/
<addon2_name>/__openerp__.py
<addon2_name>/...

Versioning

setuptools-odoo does its best to detect if an addon has changed compared to the version indicated in it’s manifest. To this end it explores the git log of the addon subtree.

If the last change to the addon corresponds to the version number in the manifest, it is used as is for the python package version. Otherwise a counter is incremented for each commit and the resulting version number has the following form: [8|9].0.x.y.z.99.devN, N being the number of git commits since the version change.

This scheme is compliant with the accepted python versioning scheme documented in PEP 440.

The 99 suffix is there to make sure it is considered as posterior to x.y.z. (.postN is ignored by pip, as specified in PEP 440, and x.y.z.devN is considered anterior to x.y.z.).

Note: for pip to install a developmental version, it must be invoked with the –pre option.

Helper API

setuptools-odoo exposes the following public API.

Many thanks to Daniel Reis who cleared the path, and Laurent Mignon who convinced me it was possible to do it using standard Python setup tools and had the idea of the odoo_addons namespace package.

Changes

1.0.0b3 (2016-02-10)

  • [ADD] mechanism to specify which Odoo version to use in dependencies (8.0, 9.0) in case some addons to be packaged have non-standard version numbers

  • [ADD] support for addons without version number in their manifest (unfortunately there are some in the wild…)

1.0.0b2 (2016-01-26)

  • [ADD] mechanism to override dependencies, to allow addon authors to require minimal versions of dependent odoo addons, and to control external python dependencies

1.0.0b1 (2015-12-29)

  • [FIX] fix postversioning when running outside git directory

  • [IMP] additional mappings for python external dependencies

  • [ADD] make_pkg_name public api to convert an addon name to a python package name

  • [ADD] make_pkg_requirement public api to obtain a valid package requirement for a given addon (same as make_pkg_name but includes requirement for the correct Odoo series)

  • [FIX] crash in case a previous commit had a bad __openerp__.py

  • first beta
