ZC buildout recipe to checkout a dir from a svn repository and archive it in a folder
Project description
This product is used to download packages from svn and tar them in a directory.
We need some buildout vars:
>>> data_dir = join(test_dir, 'data') >>> parts_dir = join(data_dir, 'parts') >>> buildout = {'instance': {'location': test_dir}, ... 'buildout': {'directory': test_dir, ... 'install-from-cache': False, ... 'download-cache':False, ... 'parts-directory': parts_dir}} >>> name = 'svn-packages'
The recipe will checkout the package from his repository and put it in the section. For testing, we need a local repository:
>>> repository = join(test_dir, 'test_repos') >>> if isdir(repository): rmtree(repository) >>> copytree(join(test_dir, 'repos'), repository) >>> if isdir(os.path.join(parts_dir, 'svn-packages')): ... rmtree(os.path.join(parts_dir, 'svn-packages'))
Then, the recipe should work:
>>> options = { ... 'urls':'file:///%s/my_package/trunk my_package' % repository} >>> from iw.recipe.subversion import Recipe >>> recipe = Recipe(buildout, name, options) >>> os.path.join(parts_dir, 'svn-packages') == recipe.install() True
Ok, we got it:
>>> ls(parts_dir, 'svn-packages') my_package
If a download-cache directory is given, then an archive is created in the specified path:
>>> cache = join(data_dir, 'cache') >>> buildout['buildout']['download-cache'] = cache >>> recipe = Recipe(buildout, name, options) >>> if isdir(cache): rmtree(cache) >>> files = recipe.install() >>> ls(cache) my_package-r4.tar.gz
Ok, now we can work offline. The package will be installed from the cache directory:
>>> rmtree(repository) >>> rmtree(parts_dir) >>> buildout['buildout']['install-from-cache'] = 'true' >>> buildout['buildout']['download-cache'] = cache >>> recipe = Recipe(buildout, name, options) >>> files = recipe.install() >>> ls(parts_dir, 'svn-packages') my_package >>> ls(parts_dir, 'svn-packages', 'my_package') __init__.py README.txt sub
Well, it’s ok for a trunk url. But when working with tagged version, we don’t want to use subversion if we already have an archive:
>>> copytree(join(test_dir, 'repos'), repository) >>> rmtree(parts_dir) >>> options = { ... 'urls':'file:///%s/my_package/tags/v1_0_0 my_package' % repository} >>> buildout['buildout']['install-from-cache'] = 'false' >>> buildout['buildout']['download-cache'] = cache >>> recipe = Recipe(buildout, name, options)
At the first time, we need to update and built the archive:
>>> recipe.need_update True >>> files = recipe.install()
But when we have an archive, we don’t need to:
>>> recipe.need_update False
Then we work offline in an online mode:
>>> rmtree(repository) >>> files = recipe.install()
Test update:
>>> recipe.update() is not None True
