- Make use of more typehints for function parameters
- Make use of typehints for function return values
- Use @var where needed to give proper hints to IDEs and avoid warnings
- Replace MockObject::setMethods() with addMethods() and onlyMethods()
- Rewording of some phpdocs
All option classes have been moved in the Predis\Configuration\Option
namespace and some have been optimized to have less impact on client
initialization timings.
Furthermore the accepted values for some options have been changed,
this is the complete list of accepted values:
- _aggregate_: callable returning an aggregate connection.
- cluster: string value ("predis", "redis"), callable returning an
aggregate connection.
- replication: string value ("predis", "sentinel"), callable returning
an aggregate connection.
- commands: command factory, named array mapping command IDs to PHP
classes, callable returning a command factory or a named array.
- connections: connection factory, callable returning a connection
factory, named array mapping connection schemes to PHP classes.
- _prefix_: string value, command processor, callable.
- _exceptions_: boolean value.
Note that the cluster and replication options now return a closure
acting as initializer instead of an aggregate connection.
This change reduces some unnecessary complexity in the library, Redis
commands do not change much after all. Developers can still implement
their own commands factory, inject new commands or override existing
ones. The "profile" client options has been renamed to "commands" and
it accepts instances of Predis\Command\FactoryInterface.
The test suite checks at runtime the version of the running instance
of Redis for integration tests to adapt itself automatically.
* Renamed SingleConnectionInterface to NodeConnectionInterface since
this name is better and makes even more sense in the context of
cluster and replication scenarios.
* Moved specialized aggregate connections (the ones implementing both
predis and redis cluster and master/slave replication) in a newly
created Predis\Connection\Aggregate sub-namespace.
* Removed the "Connection" part from names of aggregate connection
interfaces in the Predis\Connection\Aggregate sub-namespace.
* Changed "Composable" to "Composite" in the name of interfaces and
classes that can use pluggable protocol processors.
We now have a base test case class for Predis (namely PredisTestCase)
grouping various commonly used utility methods shared by all of the
tests in the suite, greatly improving reusability.
This commit is a complete rewrite of the classes previously contained
in the Predis\Option namespace aimed at lowering the initialization
overhead while bringing in more consistency. The overall idea is still
the same with a mini DI container, Predis\Configuration\Options, which
carries options with values that can be initialized lazily.
The first difference with our previous implementation is that now even
user-defined options can be initialized lazily, everything needed is
an object responding to the __invoke() magic method such as a closure.
Other kind of callable arguments (strings, arrays) will be treated as
plain values. The only drawback is that we cannot pass any instance of
classes implementing __invoke() as an option value, but considered the
limited scope of our use case we can say it's more of an acceptable
compromise. Callbacks used for lazy initialization will receive two
arguments upon invokation:
- The current instance of Predis\Configuration\Option ($options)
- A string containing the name of the option ($option)
This is an example in actual code:
$options = new Predis\Configuration\Options([
'exceptions' => true,
'profile' => '2.8',
'distributor' => function () {
return new Predis\Cluster\Distribution\KetamaPureRing();
},
'cluster' => function ($options) {
$distr = $options->distributor;
$strategy = new Predis\Cluster\PredisClusterHashStrategy($distr);
$cluster = new Predis\Connection\PredisCluster();
return $cluster;
},
'connections' => function ($options, $option) {
$factory = $options->getDefault($option);
$factory->define('tcp', 'Predis\Connection\PhpiredisConnection');
return $factory;
},
]);
As you can see there's very little difference compared to before in
the actual usage as most changes are under the hood. Some options such
as "exceptions" and "replication" can now correctly parse bool values
from strings (so the string "false" is not evaluated as boolean true).
While options were initially conceived to configure the client and its
behavior, the concept has matured and it's perfectly fine to consider
the use of Predis\Configuration\Options to propagate configurations to
inner parts of the library.
