Project description

Buildout recipe for setting up a google appengine development environment.

The rod.recipe.appengine is a zc.buildout recipe to build, test and deploy projects for the google appengine. It makes it easy to use eggs and resolve their dependencies automatically.

To be honest, this is a recipe for scrambled eggs. It produces a zip file containing all configured external packages in a traditional folder hierarchy.

A brief documentation

This recipe takes a number of options:

appengine-lib: Path to an already installed appengine library
eggs: List of required eggs
exclude: A list of basenames to be excluded when setting up the application files, e.g. the whole ‘tests’ directory.
packages: A list of packages to be included into the zip archive, which will be uploaded to the appspot.
src: The directory which contains the project source files.
url: The url for fetching the google appengine distribution
zip-name: The name of the zip archive containing all external packages ready to deploy.
zip-packages: Flag whether external packages shall be zipped in single zip file. (Default=True)

Tests

We will define a buildout template used by the recipe:

>>> buildout_template = """
... [buildout]
... develop = %(dev)s
... parts = sample
...
... [sample]
... recipe = rod.recipe.appengine
... eggs = foo.bar
... packages = bazpkg
... zip-packages = False
... exclude = tests
... url = http://googleappengine.googlecode.com/files/google_appengine_1.2.3.zip
... """

We’ll start by creating a buildout:

>>> import os.path
>>> import rod.recipe.appengine.tests as tests
>>> egg_src = os.path.join(os.path.split(tests.__file__)[0], 'foo.bar')
>>> baz_pkg = os.path.join(os.path.split(tests.__file__)[0], 'bazpkg')
>>> write('buildout.cfg', buildout_template % {'dev': egg_src+' '+baz_pkg})

Running the buildout gives us:

>>> output = system(buildout)
>>> if output.endswith("Google App Engine distribution...\n"): True
... else: print output
True

And now we try to run the appserver script:

>>> print system(os.path.join('bin', 'sample'))
<BLANKLINE>
...
Invalid arguments
<BLANKLINE>

There should be a configuration script in bin as well:

>>> print system(os.path.join('bin', 'appcfg'))
Usage: appcfg [options] <action>
<BLANKLINE>
...
<BLANKLINE>

Let’s see if the ‘tests’ directory has been excluded:

>>> l = os.listdir(os.sep.join(['parts', 'sample', 'foo', 'bar']))
>>> assert 'tests' not in l

There should be a baz package within our application directory:

>>> assert 'baz' in os.listdir(os.sep.join(['parts', 'sample']))
