Doctrine DBAL transport implementation for Jackalope

Jackalope

A powerful implementation of the PHPCR API.

Jackalope binding for relational databases with the DoctrineDBAL. Works with any database supported by doctrine (mysql, postgres, ...) and has no dependency on java or jackrabbit. For the moment, it is less feature complete.

Preconditions

• php >= 5.3
• phpunit >= 3.6 (if you want to run the tests)
• phpunit/DbUnit (if you want to run the Doctrine DBAL Transport tests)
• composer

Installation

If you do not yet have composer, install it like this

curl -s http://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin

To install jackalope itselves, run the following in the parent directory of where you want jackalope

git clone git://github.com/jackalope/jackalope-doctrine-dbal.git
cd jackalope-doctrine-dbal
php /usr/local/bin/composer.phar install --dev

Note that the --dev parameter is only needed if you want to be able to run the test suite. If you already installed jackalope without the test suite, you need to remove composer.lock before running composer again with the --dev parameter.

Create a repository

Set up a new database supported by Doctrine DBAL (i.e. mysql or postgres). You can use your favorite GUI frontend or just do something like this:

mysqladmin -u root -p  create jackalope
echo "grant all privileges on jackalope.* to 'jackalope'@'localhost' identified by '1234test'; flush privileges;" | mysql -u root -p

phpunit Tests

If you want to run the tests , please see the README file in the tests folder and check if you told composer to install the suggested dependencies (see Installation)

Enable the commands

There are a couple of useful commands to interact with the repository.

To use the console, copy cli-config.php.dist to cli-config.php and configure the connection parameters. Then you can run the commands from the jackalope directory with ``./bin/jackalope

NOTE: If you are using PHPCR inside of Symfony, the DoctrinePHPCRBundle provides the commands inside the normal Symfony console and you don't need to prepare anything special.

Jackalope specific commands:

• jackalope:init:dbal: Initialize the configured database for jackalope with the Doctrine DBAL transport.

Commands available from the phpcr-utils:

• phpcr:workspace:create <name>: Create a workspace name in the repository
• phpcr:register-node-types --allow-update [cnd-file]: Register namespaces and node types from a "Compact Node Type Definition" .cnd file
• phpcr:dump [--sys_nodes[="..."]] [--props[="..."]] [path]: Show the node names under the specified path. If you set sys_nodes=yes you will also see system nodes. If you set props=yes you will additionally see all properties of the dumped nodes.
• phpcr:purge: Remove all content from the configured repository in the configured workspace
• phpcr:sql2: Run a query in the JCR SQL2 language against the repository and dump the resulting rows to the console.

Bootstrapping

Jackalope relies on autoloading. Namespaces and folders are compliant with PSR-0. You should use the autoload file generated by composer: vendor/.composer/autoload.php

If you want to integrate jackalope into other PSR-0 compliant code and use your own classloader, find the mapping in vendor/.composer/autoload_namespaces.php

Before you can use jackalope with a database, you need to set the database up. Create a database as described above, then make sure the command line utility is set up (see above "Enable the commands"). Now you can run:

bin/jackalope jackalope:init:dbal

Once these steps are done, you can bootstrap the library. A minimalist sample code to get a PHPCR session with the doctrine-dbal backend:

$driver   = 'pdo_mysql';
$host     = 'localhost';
$user     = 'root';
$password = '';
$database = 'jackalope';
$workspace  = 'default';

// Bootstrap Doctrine
$dbConn = \Doctrine\DBAL\DriverManager::getConnection(array(
    'driver'    => $driver,
    'host'      => $host,
    'user'      => $user,
    'password'  => $pass,
    'dbname'    => $database,
));

$repository = \Jackalope\RepositoryFactoryDoctrineDBAL::getRepository(
    array('jackalope.doctrine_dbal_connection' => $dbConn)
);
// dummy credentials to comply with the API
$credentials = new \PHPCR\SimpleCredentials(null, null);
$session = $repository->login($credentials, $workspace);

To use a workspace different than default you need to create it first. The easiest is to run the command bin/jackalope phpcr:workspace:create <myworkspace> but you can of course also use the PHPCR API to create workspaces from your code.

Usage

The entry point is to create the repository factory. The factory specifies the storage backend as well. From this point on, there are no differences in the usage (except for supported features, that is).

// see Bootstrapping for how to get the session.

$rootNode = $session->getNode("/");
$whitewashing = $rootNode->addNode("www-whitewashing-de");
$session->save();

$posts = $whitewashing->addNode("posts");
$session->save();

$post = $posts->addNode("welcome-to-blog");
$post->addMixin("mix:title");
$post->setProperty("jcr:title", "Welcome to my Blog!");
$post->setProperty("jcr:description", "This is the first post on my blog! Do you like it?");

$session->save();

See PHPCR Tutorial for a more detailed tutorial on how to use the PHPCR API.

Implementation notes

See doc/architecture.md for an introduction how Jackalope is built. Have a look at the source files and generate the phpdoc.

TODO

The best overview of what needs to be done are the skipped API tests. Have a look at DoctrineDBALImplementationLoader to see what is currently not working and start hacking :-)

Some notes

• Refactor storage to implement one one table per database type?
• Optimize database storage more, using real ids and normalizing the uuids and paths?
• Implement parser for Jackrabbit CND syntax for node-type definitions in phpcr-utils.
