This recipe configure FSS Storage.

How to use iw.recipe.fss ?

The recipe is called by buildout, let’s create an instance of it, with a buildout simulated context:

>>> import os
>>> data_dir = os.path.join(test_dir, 'data')
>>> bin_dir = os.path.join(data_dir, 'bin')
>>> var_dir = os.path.join(data_dir, 'var2')
>>> conf_dir = os.path.join(data_dir, 'etc')
>>> buildout = {'instance': {'location': data_dir},
...             'buildout': {'bin-directory': bin_dir}}
>>> name = 'fss'
>>> options = {'conf': os.path.join(conf_dir,
...                                 'plone-filesystemstorage.conf'),
...            'storages': """
...                 storage1 /site/storage1
...                 storage2 /site/storage2 flat
...                 storage3 /site/storage3 flat %s/storage %s/backup
...                 """ % (var_dir, var_dir)}

Creating the recipe:

>>> from iw.recipe.fss import Recipe
>>> recipe = Recipe(buildout, name, options)

Running it:

>>> paths = list(recipe.install())

Checking files created:

>>> paths.sort()
>>> paths
['...data/etc/plone-filesystemstorage.conf',
 '...data/var/fss_backup_storage1',
 '...data/var/fss_backup_storage2',
 '...data/var/fss_storage_storage1',
 '...data/var/fss_storage_storage2',
 '...data/var2/backup',
 '...data/var2/storage']

Checking the conf file:

>>> conf = open(os.path.join(conf_dir,
...                          'plone-filesystemstorage.conf'))
>>> print conf.read()
# FSS conf file generated by iw.recipe.fss
<BLANKLINE>
# main storage storage1 for /site/storage1
storage-path /.../data/var/fss_storage_storage1
backup-path /.../data/var/fss_backup_storage1
storage-strategy directory
<BLANKLINE>
# storage storage2
<site /site/storage2>
 storage-path /.../data/var/fss_storage_storage2
 backup-path /.../data/var/fss_backup_storage2
 storage-strategy flat
</site>
<BLANKLINE>
# storage storage3
<site /site/storage3>
 storage-path /.../data/var2/storage
 backup-path /.../data/var2/backup
 storage-strategy flat
</site>
<BLANKLINE>
<BLANKLINE>

Cleaning up the files:

>>> for path in paths:
...     try:
...         os.rmdir(path)
...     except:
...         os.remove(path)
