Project description
PythonNest
Pypi mirror, with advanced export / import functionnalities compared to other Pypi mirrors.
Installing
As every Python package, you may use several ways to install PythonNest. Python 3.3+ is required, with the following packages:
setuptools >= 0.7
django >= 1.7
rpc4django >=0.3
From the source:
$ cd PythonNest $ sudo python setup.py install # global installation $ python setup.py install --user # installation without root access
With easyinstall:
$ sudo easy_install pythonnest
You can also use pip
$ sudo pip install pythonnest # global installation $ pip install pythonnest --user # installation without root access
We strongly advise to use virtualenv and gunicorn to run your server.
Virtual environment
To create a functionnal virtual env and launch the service through gunicorn (assuming mkvirtualenv is installed)
VIRTUALENV=pythonnest mkvirtualenv -p `which python3.3` $VIRTUALENV workon $VIRTUALENV pip install gunicorn pythonnest pythonnest-manage config [modify the configuration file] pythonnest-manage syncdb pythonnest-manage collectstatic gunicorn -b 0.0.0.0:8080 -D pythonnest.djangoproject.wsgi:application
If mkvirtualenv is not found, you have to search for virtualenvwrapper (thanks to apt-get, yum or pip).
Configuring
PythonNest uses a small configuration file named pythonnest.ini. Its location depends on the location of the package, more precisely on the location of the pythonnest.djangoproject.settings file.
If the location is /foo/bar/lib/baz/pythonnest/djangoproject/settings.py, then the configuration file is expected to be /foo/bar/etc/pythonnest.ini. Anyway, you should use pythonnest-manage config to display its exact location.
Its content is quite limited:
[pythonnest] ; root path for all data files (static files like CSS, and python packages) ROOT_PATH = /var/data/pythonnest ; full URI of your repository, with trailing slash (https://pypi.python.org/) HOST = http://localhost:8000/ ; activate error pages and deactive email reporting DEBUG = True ADMIN_EMAIL = admin@localhost TIME_ZONE = Europe/Paris LANGUAGE_CODE = fr-fr ; if your mirror is behind a Apache with mod_xsendfile, use this option to increase perfs USE_XSENDFILE = false ; use if you want to use Apache/NGinx HTTP authentication (both HTTP_REMOTE_USER and REMOTE_USER HTTP are used) USE_HTTP_AUTH = false ; replace 'sqlite3' by 'postgresql_psycopg2', 'mysql', or 'oracle' DATABASE_ENGINE = django.db.backends.sqlite3 ; location of your sqlite db, or name of the sql database DATABASE_NAME = ; only used with mysql, DATABASE_USER = DATABASE_PASSWORD = DATABASE_HOST = DATABASE_PORT =
The package mysql seems to be a bit broken with Python 3.3, or at least cannot be directely installed with pip.
Dumping an existing mirror
You can populate your mirror by copying an existing mirror such as pypi.python.org:
workon $VIRTUALENV pythonnest-manage update [--url http://pypi.python.org/pypi] [--init-all] [-h]
The source mirror must implement the XML-RPC API (of course, pypi.python.org does). You have to download around 10 GB to dump an official Pypi mirror if you restrict yourself to the last version of the downloaded packages.
Exporting and exporting data
If you want to maintain an offline repository, you need two PythonNest instances, the first one being able to run the update command:
workon $VIRTUALENV pythonnest-manage export [--path <path_you_want_to_export_data_to>] [--tag <tag_to_identify_this_export>] \ [--serial <serial>]
All packages imported into PythonNest (through update or import command, or added by users) are associated to a unique serial. The export command stores the last exported serial associated to the given tag. By default, the export starts to export data from the last stored serial. If you only want to dump an existing mirror and export collected data, you can delete the directory $ROOT_PATH/media/downloads after the export without breaking the database (you only need to be sure that you wan’t export these files again!).
Importing data:
workon $VIRTUALENV pythonnest manage import [--path <path_with_exported_data>] [--tag <tag_to_identify_this_import>] [--force]
Import all data previously exported by the other PythonNest instance. The last imported serial is stored into database, so any missing import can be tracked (and further importations are forbidden, unless you specify the –force option).
The tag option allow to export data to/to import from different PythonNest instances.
