 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.
+
+1.5.0b2 (2010-04-29)
+====================
+
+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.

src/zc/buildout/virtualenv.txt

+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',

+      ]

+    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.

+    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.
