Change History
**************
1.0.0b7
=======
Added a documented testing framework for use by recipes. Refactored
the buildout tests to use it.
Added a runsetup command run a setup script. This is handy if, like
me, you don't install setuptools in your system Python.

The Zope Buildout project provides support for creating applications,
The Buildout project provides support for creating applications,
especially Python applications. It provides tools for assembling
applications from multiple parts, Python or otherwise. An application
may actually contain multiple programs, processes, and configuration
settings.
Here's an example of such an application that we built with an earlier
prototype of the buildout system. We have a Zope application consisting of:
- Multiple Zope instances
- 4 ZEO servers
- An LDAP server
- Cache-invalidation and Mail delivery servers
- Dozens of add-on packages
- Multiple test runners
- Multiple deployment modes, including dev, stage, and prod,
with prod deployment over multiple servers
Parts installed include:
- Application software installs, including Zope, ZEO and LDAP
software
- Add-on packages
- Bundles of configuration that define Zope, ZEO and LDAP instances
- Utility scripts such as test runners, server-control
scripts, cron jobs.
This is all defined using configuration files and recipes, which are
software that build and installs parts based on configuration data.
The prototype system has minimal documentation and no tests and
has no egg support. (It build on earlier make-based systems that had
no documentation or tests.)
This project provides a non-prototype implementation of the ideas and
knowledge gained from earlier efforts and leverages setuptools to make
recipe management cleaner and to provide better Python package and
script management.

I expect that, for many Zope packages, we'll arrange the package
projects in subversion as buildouts. To work on the package, someone
will check the project out of Subversion and build it. Building it
will assemble all of packages and programs needed to work on it. For
example, a buildout for a project to provide a new security policy
will include the source of the policy and specifications to build the
application for working on it, including:
- a test runner
- a web server for running the user interface
- supporting packages
A buildout will typically contain a copy of bootstrap.py. When
someone checks out the project, they'll run bootstrap.py, which will
- create support directories, like bin, eggs, and work, as needed,
- download and install the zc.buildout and setuptools eggs,
- run bin/build (created by installing zc.buildout) to build the
application.
Buildouts are defined using configuration files. These files are
based on the Python ConfigParser module with some variable-definition
and substitution extensions.
Installation
************
There are two ways to install zc,buildout
1. Install it as an egg using `easy_install
<http://peak.telecommunity.com/DevCenter/EasyInstall>`_ into a
Python instaallation. Then just use the buildout script from your
Python bin or Scripts directory.
2. Use the `bootstrap script
<http://dev.zope.org/Buildout/bootstrap.py>`_ to install setuptools
and the buildout software into your buildout. Typically, you'll
check the bootstrap script into your project so that, whenever you
checkout your project, you can turn it into a buildout by just
running the bootstrap script.
More information
****************
The detailed documentation for the various parts of buildout can be
found in the following files:
`buildout.txt <http://dev.zope.org/Buildout/buildout.html>`_
Describes how to define and run buildouts. It also describes how
to write recipes.
`easy_install.txt <http://dev.zope.org/Buildout/easy_install.html>`_
Describes an Python APIs for invoking easy_install for generation
of scripts with paths baked into them.
To get a feel for some of the things you might use buildouts for, see
the `Buildout examples`_.

Buildout examples
*****************
Some simple buildout examples:
Here are a few examples of what you can do with buildouts. We'll
present these as a set of use cases.
Try out an egg
==============
`The zc.buildout project <http://svn.zope.org/zc.buildout/trunk>`_
This is the project for the buildout software itself, which is
developed as a buildout.
Sometimes you want to try an egg (or eggs) that someone has released.
You'd like to get a Python interpreter that lets you try things
interactively or run sample scripts without having to do path
manipulations. If you can and don't mind modifying your Python
installation, you could use easy_install, otherwise, you could create
a directory somewhere and create a buildout.cfg file in that directory
containing::
`The zc sharing project <http://svn.zope.org/zc.sharing/trunk>`_
This project illistrates using the buildout software with Zope 3.
Note that the bootstrap.py file is checked in so that a buildout
can be made when the project is checked out. The buildout.cfg
specified everything needed to create a Zope 3 installation with
the zc.sharing package installed in development mode.
[buildout]
parts = mypython
[mypython]
recipe = zc.recipe.egg
interpreter = mypython
eggs = theegg
where theegg is the name of the egg you want to try out.
Run buildout in this directory. It will create a bin subdirectory
that includes a mypython script. If you run mypython without any
arguments you'll get an interactive interpreter with the egg in the
path. If you run it with a script and script arguments, the script
will run with the egg in its path. Of course, you can specify as many
eggs as you want in the eggs option.
If the egg provides any scripts (console_scripts entry points), those
will be installed in your bin directory too.
Work on a package
=================
I often work on packages that are managed separately. They don't have
scripts to be installed, but I want to be able to run their tests
using the `zope.testing test runner
<http://www.python.org/pypi/zope.testing>`_. In this kind of
application, the program to be instaleld is the test runner. A good
example of this is `zc.ngi <http://svn.zope.org/zc.ngi/trunk/>`_.
Here I have a subversion project for the zc.ngi package. The software
is in the src directory. The configuration file is very simple::
[buildout]
develop = .
parts = test
[test]
recipe = zc.recipe.testrunner
eggs = zc.ngi
I use the develop option to create a develop egg based on the current
directory. I request a test script named "test" using the
zc.recipe.testrunner recipe. In the section for the test script, I
specify that I want to run the tests in the zc.ngi package.
When I check out this project into a new sandbox, I run bootstrap.py
to get setuptools and zc.buildout and create bin/buildout. I run
bin/buildout, which installs the test script, bin/test, which I can
then use to run the tests.
This is probably the most common type of buildout.
The `zc.buildout project <http://svn.zope.org/zc.buildout/trunk>`_
is a slightly more complex example of this type of buildout.
Install egg-based scripts
=========================
A variation of the `Try out an egg`_ use case is to install scripts
into your ~/bin directory (on Unix, of course). My ~/bin directory is
a buildout with a configuration file that looks like::
[buildout]
parts = foo bar
bin-directory = .
[foo]
...
whwre foo and bar are packages with scripts that I want available. As
I need new scripts, I can add additional sections. The bin-directory
option specified that scripts should be installed into the current
directory.
Multi-program multi-machine systems
===================================
Using an older prototype version of the buildout, we've build a number
of systems involving multiple programs, databases, and machines. One
typical example consists of:
- Multiple Zope instances
- Multiple ZEO servers
- An LDAP server
- Cache-invalidation and Mail delivery servers
- Dozens of add-on packages
- Multiple test runners
- Multiple deployment modes, including dev, stage, and prod,
with prod deployment over multiple servers
Parts installed include:
- Application software installs, including Zope, ZEO and LDAP
software
- Add-on packages
- Bundles of configuration that define Zope, ZEO and LDAP instances
- Utility scripts such as test runners, server-control
scripts, cron jobs.
