        ZODB
        ====
        
        Introduction
        ============
        
        The ZODB  package provides a  set of tools  for using the  Zope Object
        Database (ZODB).  The components you  get with the ZODB release are as
        follows:
        
        - Core ZODB, including the persistence machinery
        - Standard storages such as FileStorage
        - The persistent BTrees modules
        - ZEO, for scalability needs
        - documentation (needs a lot more work)
        
        Our primary development platforms are Linux, Mac OS X, and Windows
        XP.  The test suite should pass without error on all of these
        platforms, although it can take a long time on Windows -- longer if
        you use ZoneAlarm.  Many particularly slow tests are skipped unless
        you pass --all as an argument to test.py.
        
        Compatibility
        =============
        
        ZODB3 3.11 requires Python 2.6 or later.
        
        Note --
           When using ZEO and upgrading from Python 2.4, you need to upgrade
           clients and servers at the same time, or upgrade clients first and
           then servers.  Clients running Python 2.5 or 2.6 will work with
           servers running Python 2.4.  Clients running Python 2.4 won't work
           properly with servers running Python 2.5 or later due to changes in
           the way Python implements exceptions.
        
        ZODB ZEO clients from ZODB 3.2 on can talk to ZODB 3.10 servers.  ZODB
        ZEO 3.10 Clients can talk to ZODB 3.8, 3.9, and 3.10 ZEO servers.
        
        Note --
           ZEO 3.10 servers don't support undo for older clients.
        
        Prerequisites
        =============
        
        You must have Python installed. If you're using a system Python
        install, make sure development support is installed too.
        
        You also need the transaction, zc.lockfile, ZConfig, zdaemon,
        zope.event, zope.interface, zope.proxy and zope.testing packages.  If
        you don't have them and you can connect to the Python Package Index,
        then these will be installed for you if you don't have them.
        
        Installation
        ============
        
        ZODB is released as a distutils package.  The easiest ways to build
        and install it are to use `easy_install
        <http://peak.telecommunity.com/DevCenter/EasyInstall>`_, or
        `zc.buildout <http://www.python.org/pypi/zc.buildout>`_.
        
        To install by hand, first install the dependencies, ZConfig, zdaemon,
        zope.interface, zope.proxy and zope.testing.  These can be found
        in the `Python Package Index <http://www.python.org/pypi>`_.
        
        To run the tests, use the test setup command::
        
          python setup.py test
        
        It will download dependencies if needed.  If this happens, ou may get
        an import error when the test command gets to looking for tests.  Try
        running the test command a second time and you should see the tests
        run.
        
        ::
        
          python setup.py test
        
        To install, use the install command::
        
          python setup.py install
        
        
        Testing for Developers
        ======================
        
        The ZODB checkouts are `buildouts <http://www.python.org/pypi/zc.buildout>`_.
        When working from a ZODB checkout, first run the bootstrap.py script
        to initialize the buildout:
        
            % python bootstrap.py
        
        and then use the buildout script to build ZODB and gather the dependencies:
        
            % bin/buildout
        
        This creates a test script:
        
            % bin/test -v
        
        This command will run all the tests, printing a single dot for each
        test.  When it finishes, it will print a test summary.  The exact
        number of tests can vary depending on platform and available
        third-party libraries.::
        
            Ran 1182 tests in 241.269s
        
            OK
        
        The test script has many more options.  Use the ``-h`` or ``--help``
        options to see a file list of options.  The default test suite omits
        several tests that depend on third-party software or that take a long
        time to run.  To run all the available tests use the ``--all`` option.
        Running all the tests takes much longer.::
        
            Ran 1561 tests in 1461.557s
        
            OK
        
        
        Maintenance scripts
        -------------------
        
        Several scripts are provided with the ZODB and can help for analyzing,
        debugging, checking for consistency, summarizing content, reporting space used
        by objects, doing backups, artificial load testing, etc.
        Look at the ZODB/script directory for more informations.
        
        
        History
        =======
        
        The historical version numbering schemes for ZODB and ZEO are complicated.
        Starting with ZODB 3.4, the ZODB and ZEO version numbers are the same.
        
        In the ZODB 3.1 through 3.3 lines, the ZEO version number was "one smaller"
        than the ZODB version number; e.g., ZODB 3.2.7 included ZEO 2.2.7.  ZODB and
        ZEO were distinct releases prior to ZODB 3.1, and had independent version
        numbers.
        
        Historically, ZODB was distributed as a part of the Zope application
        server.  Jim Fulton's paper at the Python conference in 2000 described
        a version of ZODB he called ZODB 3, based on an earlier persistent
        object system called BoboPOS.  The earliest versions of ZODB 3 were
        released with Zope 2.0.
        
        Andrew Kuchling extracted ZODB from Zope 2.4.1 and packaged it for
        use by standalone Python programs.  He called this version
        "StandaloneZODB".  Andrew's guide to using ZODB is included in the Doc
        directory.  This version of ZODB was hosted at
        http://sf.net/projects/zodb.  It supported Python 1.5.2, and might
        still be of interest to users of this very old Python version.
        
        Zope Corporation released a version of ZODB called "StandaloneZODB
        1.0" in Feb. 2002.  This release was based on Andrew's packaging, but
        built from the same CVS repository as Zope.  It is roughly equivalent
        to the ZODB in Zope 2.5.
        
        Why not call the current release StandaloneZODB?  The name
        StandaloneZODB is a bit of a mouthful.  The standalone part of the
        name suggests that the Zope version is the real version and that this
        is an afterthought, which isn't the case.  So we're calling this
        release "ZODB". We also worked on a ZODB4 package for a while and
        made a couple of alpha releases.  We've now abandoned that effort,
        because we didn't have the resources to pursue ot while also maintaining
        ZODB(3).

        =====================
        
        Fixed: The ZODB3 "test" extra was inadvertently removed.
        
               Note that the text extra exists soley to allow other packages
               to use ``ZODB [test]`` in their test dependencies.
        
        3.11.0a1 (2012-12-01)
        =====================
        
        ZODB3 depends on:
        
        - persistent 4.0
        - BTrees 4.0
        - ZODB 4.0
        - ZEO 4.0
