Dépôt pypi de l'AUF (django-chishop)

Utilisation

setuptools

Pour utiliser le depot avec setuptools, il faut créer un fichier de configuration pour l'utilisateur qui va exécuter ces commandes.

Exemple de ~/.pypirc:

[distutils]
index-servers =
    auf
    pypi

[pypi] #pypi.python.org
username:<compte pypi>
password:<mot de passe>

[auf] #pypi.auf.org
username:<compte auf>
password:<mot de passe>
repository:http://pypi.auf.org/

Notes:

• On doit re-spécifier pypi[.python.org], sinon il ne sera pas consulté du tout, et les sections username/password sont obligatoires (pour le fichier), mais on en aura rarement besoin.

Une fois que le pypi de l'auf est configuré, on peut commencer a s'en servir. Quelques exemples:

# Installer un module
$ easy_install -f http://pypi.auf.org/media/dist/caldav-0.1.3.tar.gz

# Publier un module
$ python setup.py -r auf sdist upload

buildout

Il faut ajouter l'url de base des dépendances:

[buildout]  
find-links = http://pypi.auf.org/projet1/
    http://pypi.auf.org/projet2/

Installation / Configuration du serveur

Le serveur

• machine hôte : vz-tech.ca.auf
• N° de CT : 507
• IP : 199.84.140.25
• fqdn : pypi.auf.org

Configuration

• Documentation et téléchargement :

  • http://github.com/ask/chishop

  • http://pypi.python.org/pypi/chishop

• version utilisée : git clone git://github.com/ask/chishop.git

• répertoire de base /srv/chishop
• prérequis :

  • aptitude install python-setuptools python-MySQLdb

  • on a dû re-installer le setuptools car la version Lenny est inférieure à celle requise : easy_install -U setuptools

• système d'authentification : pypi.auf.org utilise authentification.auf.org (auf_roa_authentification)

  • importer le module auf_roa_authentification_backend dans chishop (/srv/chishop/auf_roa_authentification_backend)

  • ajouter django_roa dans le buildout :

    •     ...
          [django]
          ...
          eggs = ${buildout:eggs}
             django_roa <=1.5
          ...

  • configurer chishop pour auf_roa_authentification_backend en modifiant le fichier /srv/chishop/chishop/settings.py. Le fichier en entier (pour avoir tout ce qu'on a ajouté/modifié) :

    •     # Django settings for djangopypi project.

        # bin/django syncdb

  • on a modifié le /srv/chishop/djangopypi/models.py (en baissant la taille de certains champs) pour régler un soucis de taille de clé primaire supérieure à 1000 octet.

    •    ...
