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:

>>> write('buildout.cfg',
... """
... [buildout]
... parts=svn-package
...
... [svn-package]
... recipe=iw.recipe.subversion
... urls=
...   file:///%s/my_package/trunk my_package
... """ % repository)

We need a repository:

>>> create_repository()

Then, the recipe should work:

>>> print system(buildout)
Installing svn-package.
A    /sample-buildout/parts/svn-package/my_package/__init__.py
A    /sample-buildout/parts/svn-package/my_package/sub
A    /sample-buildout/parts/svn-package/my_package/sub/__init__.py
A    /sample-buildout/parts/svn-package/my_package/README.txt
...
<BLANKLINE>

Ok, we got it:

>>> ls('parts', 'svn-package')
d my_package

If a download-cache directory is given, then an archive is created in the specified path:

>>> write('buildout.cfg',
... """
... [buildout]
... download-cache=cache
... parts=svn-package
...
... [svn-package]
... recipe=iw.recipe.subversion
... urls=
...   file:///%s/my_package/trunk my_package
... """ % repository)

>>> rmtree('parts')
>>> cache = join(os.getcwd(), 'cache')
>>> mkdir(cache)

>>> print system(buildout)
Creating directory '/sample-buildout/parts'.
Uninstalling svn-package.
Installing svn-package.
A    /sample-buildout/parts/svn-package/my_package/__init__.py
A    /sample-buildout/parts/svn-package/my_package/sub
A    /sample-buildout/parts/svn-package/my_package/sub/__init__.py
A    /sample-buildout/parts/svn-package/my_package/README.txt
...
Creating archive: my_package-dev.tar.gz

>>> ls(cache)
d  dist
-  my_package-dev.tar.gz

Ok, now we can work offline. The package will be installed from the cache directory:

>>> write('buildout.cfg',
... """
... [buildout]
... install-from-cache=true
... download-cache=cache
... parts=svn-package
...
... [svn-package]
... recipe=iw.recipe.subversion
... urls=
...   file:///%s/my_package/trunk my_package
... """ % repository)

>>> rmtree(repository)
>>> rmtree('parts')
>>> print system(buildout)
Creating directory '/sample-buildout/parts'.
Uninstalling svn-package.
Installing svn-package.
<BLANKLINE>


>>> ls('parts', 'svn-package')
d  my_package

>>> ls('parts', 'svn-package', 'my_package')
-  README.txt
-  __init__.py
d  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:

>>> write('buildout.cfg',
... """
... [buildout]
... download-cache=cache
... parts=svn-package
...
... [svn-package]
... recipe=iw.recipe.subversion
... urls=
...   file:///%s/my_package/tags/v1_0_0 my_package
... """ % repository)

At the first time, we need to update and built the archive:

>>> create_repository()
>>> print system(buildout)
Uninstalling svn-package.
Installing svn-package.
A    /sample-buildout/parts/svn-package/my_package/__init__.py
A    /sample-buildout/parts/svn-package/my_package/sub
A    /sample-buildout/parts/svn-package/my_package/sub/__init__.py
A    /sample-buildout/parts/svn-package/my_package/README.txt
...
Creating archive: my_package-v1_0_0.tar.gz
<BLANKLINE>

>>> ls('parts', 'svn-package', 'my_package')
d  .svn
-  README.txt
-  __init__.py
d  sub

>>> ls(cache)
d  dist
-  my_package-v1_0_0.tar.gz

Then we work can work offline:

>>> write('buildout.cfg',
... """
... [buildout]
... offline=true
... download-cache=cache
... parts=svn-package
...
... [svn-package]
... recipe=iw.recipe.subversion
... urls=
...   file:///%s/my_package/tags/v1_0_0 my_package
... """ % repository)

>>> rmtree(repository)
>>> rmtree('parts')
>>> print system(buildout)
Creating directory '/sample-buildout/parts'.
Uninstalling svn-package.
Installing svn-package.
<BLANKLINE>

>>> ls('parts', 'svn-package', 'my_package')
-  README.txt
-  __init__.py
d  sub
