- 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
We have renamed most methods to drop the "command" suffix as it is quite
redundant. Due to this change and thanks to variadic methods introduced
with PHP 5.6 we took the opportunity to replace both "supportsCommand()"
and "supportsCommands()" with a single new method "supports()".
Added more stringent typehints for method arguments and typehints for
return values now that we do not need to support anything below PHP 7.2.
Also moved from using array() to [] in source code of class involved.
Promoted the "switchToMaster()" and "switchToSlave()" methods to be
part of the replication connection interface and demoted the method
"switchTo($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.
Starting with Redis 3.0.3 the EXISTS command is variadic so that it is
possible to check for the existence of multiple keys in one request,
with the server returning the number of keys found.
This change could break codebases relying on strict comparison (===)
against a boolean value, but just doing $redis->exists('key') == TRUE
is totally fine.
* 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.
Status response objects are needed mostly to make it possible from the
client perspective to differentiate a status response with the payload
"OK" from a normale bulk reply containing "OK".
The biggest change is for commands returning +OK responses: these were
previously translated to TRUE (bool value), but they are now returned
as instances of Predis\Response\Status. Just to illustrate an example
of the possibilities with this change we will use SET since it is the
most widely used command returning +OK:
$response = $client->set('foo', 'bar');
echo $response; // 'OK'
$response == 'OK'; // TRUE
isset($response->ok); // TRUE
$response == true; // TRUE
$response === true; // FALSE
$response instanceof Predis\Response\ObjectInterface; // TRUE
$response instanceof Predis\Response\Status; // TRUE
For those checking responses returned by commands such as SET or PONG,
the breaking change basically lies in the usage of strict comparison:
doing $response === true will now evaluate to FALSE instead of TRUE.
By default Predis caches common status responses such as OK or QUEUED
to lower the memory usage when using pipelines or transactions.
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.
First of all we completely removed the concept of pipeline executors.
Now pipelines can be easily customized by extending our default class
Predis\Pipeline\Pipeline.
Tests coverage for the Predis\Pipeline namespace is decent but can be
definitely improved while test cases can be beautified.
