Change History
**************
1.5.0 (unreleased)
==================
New features:
- zc.buildout supports Python 2.7.
- By default, Buildout and the bootstrap script now prefer final versions of
Buildout, recipes, and extensions. This can be changed by using the
--accept-buildout-test-releases flag (or -t for short) when calling
bootstrap. This will hopefully allow beta releases of these items to
be more easily and safely made in the future.
NOTE: dependencies of your own software are not affected by this new
behavior. Buildout continues to choose the newest available versions
of your dependencies regardless of whether they are final releases. To
prevent this, use the pre-existing switch ``prefer-final = true`` in
the [buildout] section of your configuration file (see
http://pypi.python.org/pypi/zc.buildout#preferring-final-releases) or
pin your versions using a versions section (see
http://pypi.python.org/pypi/zc.buildout#repeatable-buildouts-controlling-eggs-used).
Bugs fixed:
- You can now again use virtualenv with Buildout. The new features to let
buildout be used with a system Python are disabled in this configuration,
and the previous script generation behavior (1.4.3) is used, even if
the new function ``zc.buildout.easy_install.sitepackage_safe_scripts``
is used.

This was a re-release of 1.4.3 in order to keep 1.5.0b1 release from hurting
workflows that combined virtualenv with zc.buildout.

System Python and zc.buildout 1.5
*********************************
The 1.5 line of zc.buildout introduced a number of changes.
Problems
========
As usual, please send questions and comments to the `distutils SIG
mailing list <mailto://distutils-sig@python.org>`_. Report bugs using
the `zc.buildout Launchpad Bug Tracker
<https://launchpad.net/zc.buildout/+bugs>`_.
If problems are keeping you from your work, here's an easy way to
revert to the old code temporarily: switch to a custom "emergency"
bootstrap script, available from
http://svn.zope.org/repos/main/zc.buildout/branches/1.4/bootstrap/bootstrap.py .
This customized script will select zc.buildout 1.4.4 by default.
zc.buildout 1.4.4 will not upgrade itself unless you explicitly specify
a new version. It will also prefer older versions of zc.recipe.egg and
some other common recipes. If you have trouble with other recipes,
consider using a standard buildout "versions" section to specify older
versions of these, as described in the Buildout documentation
(http://pypi.python.org/pypi/zc.buildout#repeatable-buildouts-controlling-eggs-used).
Working with a System Python
============================
While there are a number of new features available in zc.buildout 1.5,
the biggest is that Buildout itself supports usage with a system Python.
This can work if you follow a couple of simple rules.
1. Use the new bootstrap.py (available from
svn://svn.zope.org/repos/main/zc.buildout/trunk/bootstrap/bootstrap.py).
2. Use buildout recipes that have been upgraded to work with zc.buildout 1.5
and higher. Specifically, they should use
``zc.buildout.easy_install.sitepackage_safe_scripts`` to generate
their scripts, if any, rather than ``zc.buildout.easy_install.scripts``.
See the `Recipes That Support a System Python`_ section below for more
details on recipes that are available as of this writing, and
`Updating Recipes to Support a System Python`_ for instructions on
how to update a recipe. Note that you should generally only need to
update recipes that generate scripts.
It's important to note that recipes not upgraded for zc.buildout 1.5.0
should continue to work--just not with a system Python.
Using a system Python is inherently fragile. Using a clean,
freshly-installed Python without customization in site-packages is more
robust and repeatable. See some of the regression tests added to the
1.5.0 line for the kinds of issues that you can encounter with a system
Python, and see
http://pypi.python.org/pypi/z3c.recipe.scripts#including-site-packages-and-sitecustomize
for more discussion.
However, using a system Python can be very convenient, and the
zc.buildout code for this feature has been tested by many users already.
Moreover, it has automated tests to exercise the problems that have been
encountered and fixed.
Recipes That Support a System Python
====================================
zc.recipe.egg continues to generate old-style scripts that are not safe
for use with a system Python. This was done for backwards
compatibility, because it is integral to so many buildouts and used as a
dependency of so many other recipes.
If you want to generate new-style scripts that do support system Python
usage, use z3c.recipe.scripts instead
(http://pypi.python.org/pypi/z3c.recipe.scripts). z3c.recipe.scripts has
the same script and interpreter generation options as zc.recipe.egg,
plus a few more for the new features mentioned above. In the simplest
case, you should be able to simply change ``recipe = zc.recipe.egg`` to
``recipe = z3c.recipe.scripts`` in the pertinent sections of your
buildout configuration and your generated scripts will work with a system
Python.
This is the only updated recipe as of this writing. Others should be
updated soon: see their change documents for details, or see `Updating
Recipes to Support a System Python`_ for instructions on how to update
recipes yourself.
Templates for creating Python scripts with the z3c.recipe.filetemplate
recipe can be easily changed to support a system Python.
- If you don't care about supporting relative paths, simply using a
generated interpreter with the eggs you want should be sufficient, as
it was before. For instance, if the interpreter is named "py", use
``#!${buildout:bin-directory/py}`` or ``#!/usr/bin/env
${buildout:bin-directory/py}``).
- If you do care about relative paths, (``relative-paths = true`` in
your buildout configuration), then z3c.recipe.scripts does require a
bit more changes, as is usual for the relative path support in that
package. First, use z3c.recipe.scripts to generate a script or
interpreter with the dependencies you want. This will create a
directory in ``parts`` that has a site.py and sitecustomize.py. Then,
begin your script as in the snippet below. The example assumes that
the z3c.recipe.scripts generated were from a Buildout configuration
section labeled "scripts": adjust accordingly.
::
#!${buildout:executable} -S
${python-relative-path-setup}
import sys
sys.path.insert(0, ${scripts:parts-directory|path-repr})
import site
Updating Recipes to Support a System Python
===========================================
You should generally only need to update recipes that generate scripts.
These recipes need to change from using ``zc.buildout.easy_install.scripts``
to be using ``zc.buildout.easy_install.sitepackage_safe_scripts``.
The signatures of the two functions are different. Please compare::
def scripts(
reqs, working_set, executable, dest,
scripts=None,
extra_paths=(),
arguments='',
interpreter=None,
initialization='',
relative_paths=False,
):
def sitepackage_safe_scripts(
dest, working_set, executable, site_py_dest,
reqs=(),
scripts=None,
interpreter=None,
extra_paths=(),
initialization='',
include_site_packages=False,
exec_sitecustomize=False,
relative_paths=False,
script_arguments='',
script_initialization='',
):
In most cases, the arguments are merely reordered. The ``reqs``
argument is no longer required in order to make it easier to generate an
interpreter alone. The ``arguments`` argument was renamed to
``script_arguments`` to clarify that it did not affect interpreter
generation.
The only new required argument is ``site_py_dest``. It must be the path
to a directory in which the customized site.py and sitecustomize.py
files will be written. A typical generation in a recipe will look like
this.
(In the recipe's __init__ method...)
::
self.options = options
b_options = buildout['buildout']
options['parts-directory'] = os.path.join(
b_options['parts-directory'], self.name)
(In the recipe's install method...)
::
options = self.options
generated = []
if not os.path.exists(options['parts-directory']):
os.mkdir(options['parts-directory'])
generated.append(options['parts-directory'])
Then ``options['parts-directory']`` can be used for the ``site_py_dest``
value.
If you want to support the other arguments (``include_site_packages``,
``exec_sitecustomize``, ``script_initialization``, as well as the
``allowed-eggs-from-site-packages`` option), you might want to look at
some of the code in
svn://svn.zope.org/repos/main/zc.buildout/trunk/z3c.recipe.scripts\_/src/z3c/recipe/scripts/scripts.py .
You might even be able to adopt some of it by subclassing or delegating.
The Scripts class in that file is the closest to what you might be used
to from zc.recipe.egg.
Important note for recipe authors: the code in recipes is *always run
without access to the site-packages*. This is irrespective of the
``include-site-packages`` option discussed elsewhere, which controls the
software being built, but not the environment in which Buildout itself runs.
virtualenv
==========
Using virtualenv (http://pypi.python.org/pypi/virtualenv) with the
--no-site-packages option already provided a simple way of using a
system Python. This is intended to continue to work, and some automated
tests exist to demonstrate this.
However, it is only supported to the degree that people have found it to
work in the past. The existing Buildout tests for virtualenv are only
for problems encountered previously. They are very far from
comprehensive.
Using Buildout with a system python has at least three advantages over
using Buildout in conjunction with virtualenv. They may or may not be
pertinent to your desired usage.
- Unlike ``virtualenv --no-site-packages``, Buildout's support allows you
to choose to let packages from your system Python be available to your
software (see ``include-site-packages`` in
http://pypi.python.org/pypi/z3c.recipe.scripts).
You can even specify which eggs installed in your system Python can be
allowed to fulfill some of your packages' dependencies (see
``allowed-eggs-from-site-packages`` in
http://pypi.python.org/pypi/z3c.recipe.scripts).
At the expense of some repeatability and platform dependency, this
flexibility means that, for instance, you can rely on
difficult-to-build eggs like lxml coming from your system Python.
- Buildout's implementation has a full set of automated tests.
- An integral Buildout implementation means fewer steps and fewer dependencies
to work with a system Python.

The bootstrap process prefers final versions of zc.buildout, so it has
selected the (generated-locally) 99.99 egg rather than the also-available
100.0b1 egg. We can see that in the buildout script's site.py.

... sample_buildout, 'parts', 'buildout', 'site.py')

If you want to accept early releases of zc.buildout, you either need to
specify an explicit version (using --version here and specifying the
version in the buildout configuration file using the
``buildout-version`` option or the ``versions`` option) or specify that you
accept early releases by using ``--accept-buildout-test-releases`` on the
bootstrap script.
Here's an example.
>>> ignored = system(
... zc.buildout.easy_install._safe_arg(sys.executable)+' '+
... 'bootstrap.py --accept-buildout-test-releases')
>>> print open(buildout_site_py).read() # doctest: +ELLIPSIS
"...
buildout_paths = [
'/sample/eggs/setuptools-...egg',
'/sample/eggs/zc.buildout-100.0b1-pyN.N.egg'
]
...
Notice we are now using zc.buildout 100.0b1, a non-final release.
The buildout script remembers the decision to accept early releases, and
alerts the user.
>>> print system(join('bin', 'buildout')),
... # doctest: +NORMALIZE_WHITESPACE
NOTE: Accepting early releases of build system packages. Rerun bootstrap
without --accept-buildout-test-releases (-t) to return to default
behavior.
This is accomplished within the script itself.
>>> print open(buildout_script).read() # doctest: +ELLIPSIS
#...
sys.argv.insert(1, 'buildout:accept-buildout-test-releases=true')
print ('NOTE: Accepting early releases of build system packages. Rerun '
'bootstrap without --accept-buildout-test-releases (-t) to return to '
'default behavior.')
...
As the note says, to undo, you just need to re-run bootstrap without
--accept-buildout-test-releases.
>>> ignored = system(
... zc.buildout.easy_install._safe_arg(sys.executable)+' '+

Now we will try the `--version` option, which lets you define a version for

Options:
-h, --help show this help message and exit
-v VERSION, --version=VERSION
use a specific zc.buildout version
-d, --distribute Use Distribute rather than Setuptools.
--setup-source=SETUP_SOURCE
Specify a URL or file location for the setup file. If
you use Setuptools, this will default to
http://peak.telecommunity.com/dist/ez_setup.py; if you
use Distribute, this will default to http://python-
distribute.org/distribute_setup.py.
--download-base=DOWNLOAD_BASE
Specify a URL or directory for downloading zc.buildout
and either Setuptools or Distribute. Defaults to PyPI.
--eggs=EGGS Specify a directory for storing eggs. Defaults to a
temporary directory that is deleted when the bootstrap
script completes.
-t, --accept-buildout-test-releases
Normally, if you do not specify a --version, the
bootstrap script and buildout gets the newest *final*
versions of zc.buildout and its recipes and extensions
for you. If you use this flag, bootstrap and buildout
will get the newest releases even if they are alphas
or betas.
-c CONFIG_FILE Specify the path to the buildout configuration file to
be used.

In buildout version 2, all final releases will be preferred by
default--that is ``prefer-final`` will also default to 'true'. You will
then need to use a 'false' value for ``prefer-final`` to get the newest
releases.
A separate option controls the behavior of the build system itself.
When buildout looks for recipes, extensions, and for updates to itself,
it does prefer final releases by default, as of the 1.5.0 release. The
``accept-buildout-test-releases`` option will let you override this behavior.
However, it is typically changed by the --accept-buildout-test-releases
option to the bootstrap script, since bootstrapping is the first step to
selecting a buildout.

View file @ 5efabe68
Version 1.5.0 of buildout (and higher) provides the ability to use
buildout directly with a system Python if you use z3c.recipe.scripts or
other isolation-aware recipes that use the sitepackage_safe_scripts function.
Some people use virtualenv to provide similar functionality.
Unfortunately, a problem with the virtualenv executable as of this
writing means that -S will not work properly with it (see
https://bugs.launchpad.net/virtualenv/+bug/572545). This breaks
buildout's approach to providing isolation.
Because of this, if buildout detects an executable with a broken -S
option, it will revert to its pre-1.5.0 behavior. If buildout has been
asked to provide isolation, it will warn the user that isolation will
not be provided by buildout, but proceed. This should give full
backwards compatibility to virtualenv users.
The only minor annoyance in the future may be recipes that explicitly
use the new buildout functionality to provide isolation: as described
above, the builds will proceed, but users will receive warnings that
buildout is not providing isolation itself. The warnings themselves can
be squelched when running bin/buildout with the ``-s`` option or with a
lower verbosity than usual (e.g., one or more ``-q`` options).
For tests, then, we can examine several things. We'll focus on four.
- Running bootstrap with an executable broken in this way will not try to do
any -S tricks.
- Running sitepackage_safe_scripts with a virtualenv will create an
old-style script. This will affect the bin/buildout script that is
created, for instance. If the sitepackage_safe_scripts function is asked
to provide isolation under these circumstances, it will warn that isolation
will not be available, but still create the desired script.
- Using the easy_install Installer or install or build functions and trying
to request isolation will generate a warning and then the isolation request
will be ignored as it proceeds.
- Passing -s (or -q) to the bin/buildout script will squelch warnings.
Testing these involves first creating a Python that exhibits the same
behavior as the problematic one we care about from virtualenv. Let's do that
first.

True
Well, that was ugly, but it seems to have done the trick. The
executable represented by py_path has the same problematic
characteristic as the virtualenv one: -S results in a Python that does
not allow the import of some packages from the standard library. We'll
test with this.
First, let's try running bootstrap.
>>> from os.path import dirname, join
>>> import zc.buildout
>>> bootstrap_py = join(
... dirname(
... dirname(
... dirname(
... dirname(zc.buildout.__file__)
... )
... )
... ),
... 'bootstrap', 'bootstrap.py')
>>> broken_S_buildout = tmpdir('broken_S')
>>> os.chdir(broken_S_buildout)
>>> write('buildout.cfg',
... '''
... [buildout]
... parts =
... ''')
>>> write('bootstrap.py', open(bootstrap_py).read())
>>> print 'X'; print system(
... _safe_arg(py_path)+' '+
... 'bootstrap.py'); print 'X' # doctest: +ELLIPSIS
X...
Generated script '/broken_S/bin/buildout'.
...
If bootstrap didn't look out for a broken -S, that would have failed. Moreover,
take a look at bin/buildout:
>>> cat('bin', 'buildout')
#!/executable_buildout/bin/py
<BLANKLINE>
import sys
sys.path[0:0] = [
'/broken_S/eggs/setuptools-0.0-pyN.N.egg',
'/broken_S/eggs/zc.buildout-0.0-pyN.N.egg',
]
<BLANKLINE>
import zc.buildout.buildout
<BLANKLINE>
if __name__ == '__main__':
zc.buildout.buildout.main()
That's the old-style buildout script: no changes for users with this issue.
Of course, they don't get the new features either, presumably because
they don't need or want them. This means that if they use a recipe that
tries to use a new feature, the behavior needs to degrade gracefully.
Here's an example. We'll switch to another buildout in which it is easier to
use local dev versions of zc.buildout and z3c.recipe.scripts.
>>> os.chdir(dirname(dirname(buildout)))
>>> write('buildout.cfg',
... '''
... [buildout]
... parts = eggs
... find-links = %(link_server)s
...
... [primed_python]
... executable = %(py_path)s
...
... [eggs]
... recipe = z3c.recipe.scripts
... python = primed_python
... interpreter = py
... eggs = demo
... ''' % globals())
>>> print system(buildout) # doctest: +NORMALIZE_WHITESPACE +ELLIPSIS
Installing eggs.
Getting distribution for 'demo'.
Got demo 0.4c1.
Getting distribution for 'demoneeded'.
Got demoneeded 1.2c1.
Generated script '/sample-buildout/bin/demo'.
Generated interpreter '/sample-buildout/bin/py'.
...UserWarning: Buildout has been asked to exclude or limit site-packages
so that builds can be repeatable when using a system Python. However,
the chosen Python executable has a broken implementation of -S (see
https://bugs.launchpad.net/virtualenv/+bug/572545 for an example
problem) and this breaks buildout's ability to isolate site-packages.
If the executable already has a clean site-packages (e.g., using
virtualenv's ``--no-site-packages`` option) you may be getting
equivalent repeatability. To silence this warning, use the -s argument
to the buildout script. Alternatively, use a Python executable with a
working -S (such as a standard Python binary).
warnings.warn(BROKEN_DASH_S_WARNING)
<BLANKLINE>
So, it did what we asked as best it could, but gave a big warning. If
you don't want those warnings for those particular recipes that use the
new features, you can use the "-s" option to squelch the warnings.
>>> print system(buildout + ' -s')
Updating eggs.
<BLANKLINE>
A lower verbosity (one or more -q options) also quiets the warning.
>>> print system(buildout + ' -q')
<BLANKLINE>
Notice that, as we saw before with bin/buildout, the generated scripts
are old-style, because the new-style feature gracefully degrades to the
previous implementation when it encounters an executable with a broken
dash-S.
