Firebird driver for the Doctrine DBAL.

This library is completely separate (i.e. abstracted away) from the core Doctrine DBAL library. I.e. it is fully a plug-in.

Requirements

To utilize this library in your application code, the following is required:

Firebird version 2.5.*
- Version 3.* is not supported. You are very welcome to provide a pull request for this.
PHP >= 7.1
PHP extensions¹:
- ibase
- mbstring
- xml
doctrine/dbal: >=2.5 <=2.5.13

¹ Only needed on remote/guest OS, e.g. a remote Ubuntu server or a VM installed through Docker, Vagrant, or XAMPP.

License & Disclaimer

See LICENSE file. Basically: Use this library at your own risk.

Limitations of Schema Manager

This library does not fully support generation through the Schema Manager, i.e.:

Generation of database tables, views, etc. from entities.
Generation of entities from database tables, views, etc.

Reasons for not investing time in schema generation include that Firebird does not allow renaming of tables, which in turn makes automated schema updates annoying and over-complicated. Better results are probably achieved by writing manual migrations.

Installation

Via Composer (kafoso/doctrine-firebird-driver):

composer install kafoso/doctrine-firebird-driver

Via Github:

git clone git@github.com:kafoso/doctrine-firebird-driver.git

Configuration

Manual configuration

For example of configuration in PHP, see tests/tests/Test/Integration/AbstractIntegrationTest.php (in the method setUp).

Additional help may be found at: https://www.doctrine-project.org/projects/doctrine-orm/en/2.5/reference/advanced-configuration.html

Symfony configuration (YAML)

This driver may be used like any other Doctrine DBAL driver in Symfony. However, the driver_class option must be specified instead of simply driver. This is due to the driver not being part of the core Doctrine DBAL library.

Sample YAML configuration:

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver_class:   Kafoso\DoctrineFirebirdDriver\Driver\FirebirdInterbase\Driver
                host:           "%database_host%"
                port:           "%database_port%"
                dbname:         "%database_name%"
                user:           "%database_user%"
                password:       "%database_password%"
                charset:        "UTF-8"

Tests

Test/development requirements

To run tests, fix bugs, provide features, etc. the following is required:

A system capable of running a virtual machine with ubuntu/xenial64.
Virtualbox >= 5.1.0
Vagrant >= 2.0.0

You may of course install everything manually using your own VM setup. For help and a stack list (required apt-get packages), see the Vagrantfile.

Installation to run tests

A few steps are required to run all tests. Unit tests (tests/tests/Test/Unit) will run on all environments. However, integration tests (tests/tests/Test/Integration) require the following because they test against a running Firebird database in the VM:

vagrant up
Install/provision the VM.
vagrant ssh
sudo su
apt-get -y install firebird2.5-superclassic
You will be prompted to install the database using a password. Please provide this password: 88fb9f307125cc397f70e59c749715e1. It is re-used when connecting through the DBAL later on.
dpkg-reconfigure firebird2.5-superclassic
Starts the Firebird database server. Provide same password as above.

Reference: https://firebirdsql.org/manual/ubusetup.html

Running tests

Due to the database being created by the PHP bootstrap script on the fly, root is needed to run the tests on the VM.

vagrant ssh
sudo su
apt-get install zip -y (for when installing composer packages)
Install composer (on guest OS). Follow these instructions: https://getcomposer.org/download/
mv composer.phar /usr/bin/composer
cd /var/git/kafoso/doctrine-firebird-driver
composer install¹
cd /var/git/kafoso/doctrine-firebird-driver/tests
php ../bin/phpunit tests

¹ Composer will say you shouldn't run it as root/super user. This is techically true, but it's fine in the VM.

Fundamental Doctrine DBAL implementation. The driver and platform logic in this library is based on other implementations in the core library, largely \Doctrine\DBAL\Driver\PDOOracle\Driver and \Doctrine\DBAL\Platforms\OraclePlatform, and their respective parent classes.

https://github.com/helicon-os/doctrine-dbal

Whilst a great inspiration for this library - and we very much appreciate the work done by the authors - the library has a few flaws and limitations regarding the Interbase Firebird driver logic:

It contains bugs. E.g. incorrect/insufficient handling of nested transactions and save points.
It is lacking with respect to test coverage.
It appears to no longer be maintained. Possibly entirely discontinued.
It is intermingled with the core Doctrine DBAL code, making version management and code adaptation unnecessarily complicated; a nightmare, really. It is forked from https://github.com/doctrine/dbal, although, this is not specifically stated.
It is not a Composer package (not on https://packagist.org).
