- 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.
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.
This change actually had a positive impact on the design of the whole
internals for clustering which is now cleaner and easier to maintain.
It is still far from perfect, but we also have to keep performances in
consideration so we can say that we ended up with a good compromise.
Previously Predis assigned an hash to each command instance which was
computed from its key, now we changed approach and the library caches
the slot assigned to each command. This works for both our client-side
sharding cluster and the upcoming redis-cluster, but the former is the
one that needed most changes.
The PredisCluster aggregate connection now only takes an instance of
StrategyInterface, which in turn wraps the chosen distributor. After
all, in order to be able to calculate the assigned slot for a command
or key, the cluster strategy must have access to the distributor that
manages the distribution of the whole keyspace. Nothing really changes
in terms of configurability as it is still possible to decide which
distributor to use for client-side sharding, it is simply different:
$distributor = new Predis\Cluster\Distribution\KetamaRing();
$strategy = new Predis\Cluster\PredisStrategy($distributor);
$cluster = new Predis\Connection\Aggregate\PredisCluster($strategy);
As for the RedisCluster aggregate connection, the only change is that
the mathematical operation of calculating the assigned slot from a key
has been completely moved inside the cluster strategy instance.
The strategy for redis-cluster does not use external distributors so
trying to StrategyInterface::getDistributor() will throw an exception.
This may change in future releases, but this is not a priority since
redis-cluster relies on a fixed, well-defined distribution mechanism.
This commit represents a breaking change when the first occurrence of
"{}" is found in a key because it will produce a different hash than
previous versions of Predis, thus leading to a different partitioning.
If you really need to stick with the old behavior, you can subclass
Predis\Cluster\PredisStrategy and override extractKeyTag() using the
old implementation of this method and pass the strategy instance when
initializing the cluster connection via client options.
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.
We also changed our wording to indentify this kind of abstraction so
instead of using "scripted commands" (kind of broken English) we now
use "scriptable commands".
