3.7.0

  • Start adding PHP 8 support

3.1.2 (in progress)

  • Dropped CI testing for php 5.5. This library should still be compatible, with 5.5 and 5.4 but travis setups are failing because of a potential GnuTLs or pycurl bug (Launchpad Bug #926548)

3.1.1

  • Fixed issue #51 by implementing deserialization support for g:T
  • Added testing around issue #51
  • Added support for gremlin-server 3.4.0
  • Fixed some incorrect tests
  • Fixed an issue where the driver's websocket handshake confirmation did not acknowledge HTTP header case insensitivity. This created issues with gremlin-server 3.4.0 as it's upgraded netty version was sending headers in all lowercase.

3.1.0

  • Fixed an issue where no response from the server during the websocket handshake would throw an obscured error. Issue #43
  • Made changes to support the testing of gremlin-server 3.2.8 & 3.3.2. This change, however, affects the testing of the driver against v3.3.0 (worth noting)
  • Updated the README.md file to reflect the correct require version for the library (ie: 3.*)
  • Updated the server install script to allow for a more flexible selection of the server install directory
  • Changed the travis configuration. Reinstated php 5.5 testing and temporarily disabled testing for hhvm as there seems to be an issue surrounding phpunit
  • Fixed the webtest.php file to support newer versions of PHPunit.
  • Fixed an issue where using authentication and sessions could fail to maintain the session
  • Added a basic GraphSON 3.0 serializer. Until gremlin server 3.2.x is no longer maintained, bellow will be the correct way of setting the serializer up. 
    $db = new Connection();
$db->message->registerSerializer('\Brightzone\GremlinDriver\Serializers\Gson3', TRUE);
    This will later be changed to the default. After which a serializer option will be added to Connection
  • Added a test suit for GraphSON 3.0 and modified travis to run the newly implemented suits

3.0.2

  • Fixed an issue with deprecated use of references failing in PHP 7+. Corrects #34
  • Corrected some travis issue. Bypassed travis PHP 5.5 tests as they were failing (due to incorrect travis configuration)
  • Fixed an issue with gremlin-server >= 3.2.5 error messages not being handled properly. Now gremlin-php driver displays stack traces correctly.
  • Modified the structure for server files. Allows separate configuration per server version.
  • Corrected some deprecated gremlin queries in tests which created failure on gremlin server 3.3.x
  • Modified install scripts and 3.3.x configuration files for testing/travis
  • Corrected issue #37
  • Added an easy access web test php file that allows users to run the tests from the browser as a convenience. And updated the README.md to reflect this

3.0.1

  • Fixed an issue where the retry strategy would be applied on an error code 500 when in reality it should have been applied on 597

3.0.0

  • Dropped testing and support for PHP 5.4. It is worth noting that we no longer test against 5.4 but this does not mean the library will not execute properly on 5.4.

  • Added support for Aliases. You can implement them either globally or locally as shown bellow:

    // Global
$db = new Connection([
     'graph' => 'graph',
     'aliases' => ["somethingcrazy" => "g"]
]);
$db->open();

$result = $db->send("somethingcrazy.V().count()");
    // Local
$db = new Connection([
     'graph' => 'graph',
]);
$db->open();

$db->message->setArguments([
     'aliases' => ['somethingcrazy'=>'g'],
]);
$result = $db->send("somethingcrazy.V().count()");

  • Added tests for aliases

  • Added tests to manageTransaction which allows session requests to auto commit transactions on each request (or rollback if error). The code bellow will actually commit the added vertex to the graph since the transaction is auto managed on the request level:

    $db = new Connection([
     'graph' => 'graphT',
]);
$db->open();

$db->transactiontart();
$db->transactionStart();

$db->message->setArguments([
     'manageTransaction' => TRUE,
]);
$db->message->gremlin = 't.addV()';
$db->send();

$db->transactionStop(FALSE);

  • Added a test for scriptEvaluationTimeout.

  • Added support for a custom saslMechanism for authentication. By default gremlin-server ignores this feature. But custom gremlin-server builds may require it. You can simply define it as follows:

    $db = new Connection([
     'graph' => 'graphT',
     'saslMechanism' => 'GSSAPI', // defaults to 'PLAIN'
]);
$db->open();

  • Updated testing and travis to use gremlin-server 3.2.1

  • Added a public method closeSession() that allows developpers to manually close a server side session. (used to be that sessions would only be closed on a call to close() which also closed the websocket.

2.2.3

  • Corrected an issue where using a custom mimeType for requests was producing an error.
  • Updated testing build to use gremlin-server v3.1.1
  • Added several new test cases.

2.2.2

  • Generalized some stream get behavior to be consistant accross all operations. This can correct some issues with hhvm streaming content before it's done loading in the socket.

2.2.1

  • Added a fix for large result sets in hhvm (and a test case)

2.2.0

  • Added a few more test cases around existing features

  • Added support for a Connection::$emptySet property. When this property is set to TRUE then empty result sets will no longer throw a ServerException (this was default). Instead they will return an empty array:

    $db = new Connection([
    'host' => 'localhost',
    'port' => 8182,
    'graph' => 'graph',
    'emptySet' => TRUE
]);
$db->open();

$result = $db->send("g.V().has('name', 'doesnotexist')");
print_r($result); // Array()

2.1.2

  • Upgraded the testing process to use gremlin-server 3.0.2

  • Corrected a bug where ssl would not work for users of PHP 5.6+. These users will now need to configure ssl as follows:

    $db = new Connection([
    'host' => 'localhost',
    'graph' => 'graph',
    'ssl' => [
        "ssl"=> [
            "cafile" => "/path/to/bundle/ca-bundle.crt",
            "verify_peer"=> true,
            "verify_peer_name"=> true,
        ]
    ]
]);

2.1.1

  • Made changes to explicit some server errors that were previously hidden from the user

2.1.0

  • Added support for fail-retry strategies on transactions:

    $db = new Connection([
    'host' => 'localhost',
    'port' => 8182,
    'graph' => 'graphT',
    'retryAttempts' => 10
]);
$db->open();

$db->transaction(function() use($db){
    $db->send('n.addVertex("name","michael")');
    $db->send('n.addVertex("name","john")');
});

$db->close();

2.0.0

2.0 supports TP 3.0.1 with authentication features. There was a major overhaul of the code in order to make the API clearer and to stick to PSR-4 namespaces. Bellow are the BC breaking changes you will need to make if you are upgrading from v1.0 :

Breaking changes

  • Namespaces currently changed from \brightzone\rexpro\* to \Brightzone\GremlinDriver\* and so forth all in CamelCase. You will need to change these in your code to reflect the change.

  • The Message class has been changed from \Brightzone\GremlinDriver\Messages to \Brightzone\GremlinDriver\Message. I you use messages directly in your code you will need to switch for the newer one.

  • Tests have been moved from src/tests to tests/. This probably doesn't affect you, but just incase.

  • Connection::open() does not take any params anymore. You need to define all connection parameters by providing them to the Connection constructor. For example:

    $db = Connection();
$db->open('localhost:8182', 'graph', 'username', 'password');

    becomes :

    $db = Connection([
   'host' => 'localhost', //default
   'port' => 8182, //default
   'graph' => 'graph',
   'username' => 'username',
   'password' => 'password'
]);
$db->open();

    This is reflected in the README examples.

1.0

Original release.
