Previously it was possible to create a new instance of Predis\Client using
the alias of a single connection in a cluster of connections. Now we added
the ability to do this also when using master/slave replication.
When the "replication" option is specified and evaluates to true, the array of
connection parameters passed to the client constructor os be used to initialize
a new instance of Predis\Network\IConnectionReplication. This option can also
accept a callable object used as an initializer or the fully-qualified name of
a class.
Fix also a few bugs found while rewriting the test suite.
In order to be able to run integration tests, the test suite requires
a version of Redis >= 2.4.0.
The units have been splitted into several different groups using
PHPUnit @group annotation to allow developers to enable, disable
and combine certain types of tests. The available groups are:
- disconnected: can run without a Redis server online
- connected: active connection to a Redis server is required
- commands: test dedicated to a specific Redis command
- slow: performs operations that can slow down execution;
A list of the available groups can be obtained by running
phpunit --list-groups
Groups of tests can be disabled or enabled via the XML configuration
file or the standard command-line test runner. Please note that due
to a bug in PHPUnit, older versions ignore the --group option when
the group is excluded in the XML configuration file. Please refer to
http://github.com/sebastianbergmann/phpunit/issues/320 for details
Integration tests in the @connected group check if the command being
tested is defined in the selected server profile (see the value of
the TEST_SERVER_VERSION constant in phpunit.xml). If the command is
not defined in the target server profile, the integration test is
automatically marked as skipped.
We also provide an helper script in the bin directory that can be
used to automatically generate a file with the scheleton of a test
case for a Redis command by specifying the name of the class in the
Predis\Commands namespace. For example, to generate a test case for
SET (represented by the Predis\Commands\StringSet class):
./bin/generate-command-test.php --class=StringSet
The realm of a command is automatically inferred from the name of the
class, but it can be set using the --realm option.
When the argument of 'profile' is an instance of Predis\Profiles\IServerProfile
the value of the 'prefix' option is ignored, which means that it is up to the
user to initialize the appropriate prefix processor.
This is a starting point to add a documentation of the whole set of APIs and
classes of Predis. The next step will be to actually improve and extend it.
When a callback is specified, the client does not return a new instance
of Predis\PubSubContext but it invokes that callback on each message
received. The context can be aborted simply by returning FALSE from the
callback.
