Merged amos-dependency-links branch to trunk (r80906:81181). 

Now there's a buildout option (use-dependency-links) that allows you to 
disable setuptool dependency_links metadata.

1.0.0b31 (2007-???)
=====================
Feature Changes
---------------
- Added a configuration option that allows buildouts to ignore
dependency_links metadata specified in setup. By default
dependency_links in setup are used in addition to buildout specified
find-links. This can make it hard to control where eggs come
from. Here's how to tell buildout to ignore URLs in
dependency_links::
[buildout]
use-dependency-links = false
By default use-dependency-links is true, which matches the behavior
of previous versions of buildout.

----------------

when it looks for dependencies. This behavior can be controlled with
the use-dependency-links buildout option.
[buildout]
...
use-dependency-links = false
The option defaults to true. If you set it to false, then dependency
links are only looked for in the locations specified by find-links.
Let's see this feature in action. To begin, let's create a new egg
repository. This repository uses the same sample eggs as the normal
testing repository.
>>> link_server2 = start_server(sample_eggs)
Turn on logging on this server so that we can see when eggs are pulled
from it.
>>> get(link_server2 + 'enable_server_logging')
GET 200 /enable_server_logging
''
Let's create a develop egg in our buildout that specifies
dependency_links which point to the new server.
>>> mkdir(sample_buildout, 'depdemo')
>>> write(sample_buildout, 'depdemo', 'dependencydemo.py',
... 'import eggrecipedemoneeded')
>>> write(sample_buildout, 'depdemo', 'setup.py',
... '''from setuptools import setup; setup(
... name='depdemo', py_modules=['dependencydemo'],
... install_requires = 'demoneeded',
... dependency_links = ['%s'],
... zip_safe=True, version='1')
... ''' % link_server2)
Now let's configure the buildout to use the develop egg.
>>> write(sample_buildout, 'buildout.cfg',
... '''
... [buildout]
... develop = depdemo
... parts = eggs
...
... [eggs]
... recipe = zc.recipe.egg:eggs
... eggs = depdemo
... ''')
Now we can run the buildout.
>>> print system(buildout)

GET 200 /demoneeded-1.2c1.zip
Develop: '/sample-buildout/depdemo'
Installing eggs.
Getting distribution for 'demoneeded'.
Got demoneeded 1.2c1.
<BLANKLINE>
Notice that the egg was retrieved from the logging server.
Now let's change the egg so that it doesn't specify dependency links.
>>> write(sample_buildout, 'depdemo', 'setup.py',
... '''from setuptools import setup; setup(
... name='depdemo', py_modules=['dependencydemo'],
... install_requires = 'demoneeded',
... zip_safe=True, version='1')
... ''')
Now we'll remove the existing dependency egg, and rerunning the
buildout to see where the egg comes from this time.
>>> from glob import glob
>>> from os.path import join
>>> def remove_demoneeded_egg():
... for egg in glob(join(sample_buildout, 'eggs', 'demoneeded*.egg')):
... remove(sample_buildout, 'eggs', egg)

<BLANKLINE>
Now it can't find the dependency since neither the buildout
configuration nor setup specifies where to look.
Let's change things so that the buildout configuration specifies where
to look for eggs.
>>> write(sample_buildout, 'buildout.cfg',
... '''
... [buildout]
... develop = depdemo
... parts = eggs
... find-links = %s
...
... [eggs]
... recipe = zc.recipe.egg:eggs

... ''' % link_server)
>>> print system(buildout)
Develop: '/sample-buildout/depdemo'
Installing eggs.
Getting distribution for 'demoneeded'.
Got demoneeded 1.2c1.
<BLANKLINE>
This time the dependency egg was found on the server without logging
configured.
Now let's change things once again so that both buildout and setup
specify different places to look for the dependency egg.
>>> write(sample_buildout, 'depdemo', 'setup.py',
... '''from setuptools import setup; setup(
... name='depdemo', py_modules=['dependencydemo'],
... install_requires = 'demoneeded',
... dependency_links = ['%s'],
... zip_safe=True, version='1')
... ''' % link_server2)
>>> remove_demoneeded_egg()

GET 200 /...
Develop: '/sample-buildout/depdemo'
Updating eggs.
Getting distribution for 'demoneeded'.
Got demoneeded 1.2c1.
<BLANKLINE>
So when both setuptools and buildout specify places to search for
eggs, the dependency_links takes precedence over find-links.
There is a buildout option that you can specify to change this
behavior. It is the use-dependency-links option. This option defaults
to true. When you specify false for this option, buildout will ignore
dependency_links and only look for eggs using find-links.
Here is an example of using this option to disable dependency_links.
>>> write(sample_buildout, 'buildout.cfg',
... '''
... [buildout]
... develop = depdemo
... parts = eggs
... find-links = %s
... use-dependency-links = false
...
... [eggs]
... recipe = zc.recipe.egg:eggs
... eggs = depdemo
... ''' % link_server)
>>> remove_demoneeded_egg()
>>> print system(buildout)
Develop: '/sample-buildout/depdemo'
Updating eggs.
Getting distribution for 'demoneeded'.
Got demoneeded 1.2c1.
<BLANKLINE>
Notice that this time the egg isn't downloaded from the logging server.
If we set the option to true, things return to the way they were
before. The dependency's are looked for first in the logging server.
>>> write(sample_buildout, 'buildout.cfg',

Dependency links
----------------
Setuptools allows metadata that describes where to search for package
dependencies. This option is called dependency_links. Buildout has its
own notion of where to look for dependencies, but it also uses the
setup tools dependency_links information if it's available.
Let's demo this by creating an egg that specifies dependency_links.
To begin, let's create a new egg repository. This repository hold a
newer version of the 'demoneeded' egg than the sample repository does.
>>> repoloc = tmpdir('repo')
>>> from zc.buildout.tests import create_egg
>>> create_egg('demoneeded', '1.2', repoloc)
>>> link_server2 = start_server(repoloc)
Turn on logging on this server so that we can see when eggs are pulled
from it.
>>> get(link_server2 + 'enable_server_logging')
GET 200 /enable_server_logging
''
Now we can create an egg that specifies that its dependencies are
found on this server.
>>> repoloc = tmpdir('repo2')
>>> create_egg('hasdeps', '1.0', repoloc,
... install_requires = "'demoneeded'",
... dependency_links = [link_server2])
Let's add the egg to another repository.
>>> link_server3 = start_server(repoloc)
Now let's install the egg.
>>> example_dest = tmpdir('example-install')
>>> workingset = zc.buildout.easy_install.install(
... ['hasdeps'], example_dest,
... links=[link_server3], index=link_server3+'index/')
GET 200 /
GET 200 /demoneeded-1.2-pyN.N.egg
The server logs show that the dependency was retrieved from the server
specified in the dependency_links.
Now let's see what happens if we provide two different ways to retrieve
the dependencies.
>>> rmdir(example_dest)
>>> example_dest = tmpdir('example-install')
>>> workingset = zc.buildout.easy_install.install(
... ['hasdeps'], example_dest, index=link_server+'index/',
... links=[link_server, link_server3])
GET 200 /
GET 200 /demoneeded-1.2-pyN.N.egg
Once again the dependency is fetched from the logging server even
though it is also available from the non-logging server. This is
because the version on the logging server is newer and buildout
normally chooses the newest egg available.
If you wish to control where dependencies come from regardless of
dependency_links setup metadata use the 'use_dependency_links' option
to zc.buildout.easy_install.install().
>>> rmdir(example_dest)
>>> example_dest = tmpdir('example-install')
>>> workingset = zc.buildout.easy_install.install(
... ['hasdeps'], example_dest, index=link_server+'index/',
... links=[link_server, link_server3],
... use_dependency_links=False)
Notice that this time the dependency egg is not fetched from the
logging server. When you specify not to use dependency_links, eggs
will only be searched for using the links you explicitly provide.
Another way to control this option is with the
zc.buildout.easy_install.use_dependency_links() function. This
function sets the default behavior for the zc.buildout.easy_install()
function.
>>> zc.buildout.easy_install.use_dependency_links(False)
True
The function returns its previous setting.
>>> rmdir(example_dest)
>>> example_dest = tmpdir('example-install')
>>> workingset = zc.buildout.easy_install.install(
... ['hasdeps'], example_dest, index=link_server+'index/',
... links=[link_server, link_server3])
It can be overridden by passing a keyword argument to the install
function.
>>> rmdir(example_dest)
>>> example_dest = tmpdir('example-install')
>>> workingset = zc.buildout.easy_install.install(
... ['hasdeps'], example_dest, index=link_server+'index/',
... links=[link_server, link_server3],
... use_dependency_links=True)
GET 200 /demoneeded-1.2-pyN.N.egg
