-
Dropped support for PHP 7.1 and older
-
Accepted values for some client options have changed, this is the new 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 object returning a connection
factory, named array mapping URI schemes to PHP classes, string identifying
a supported combination of configurations for the connection factory.prefix
: string value, command processor, callable.exceptions
: boolean.
Note that both the
cluster
andreplication
options now return a closure
acting as initializer instead of an aggregate connection instance. -
The
connections
client option now accepts certain string values identifying
certain combinations of configurations for the connection factory. Currenlty
this is used to provide a short way to configure Predis to load our phpiredis
based connection backends simply, accepted values are:phpiredis-stream
mapsPhpiredis\Connection\PhpiredisStreamConnection
to
tcp
,redis
,unix
URI schemes.phpiredis-socket
mapsPhpiredis\Connection\PhpiredisSocketConnection
to
tcp
,redis
,unix
URI schemes.phpiredis-stream
is simply an alias ofphpiredis-stream
.
-
Added the new
Predis\Cluster\Hash\PhpiredisCRC16
class using ext-phpiredis
to speed-up the generation of the CRC16 hash of keys for redis-cluster. Predis
automatically uses this class when ext-phpiredis is loaded, but it is possible
to configure the hash generator using the newcrc16
client option (accepted
valuespredis
,phpiredis
or an hash generator instance). -
Replication backends now use the
role
parameter instead ofalias
in order
to distinguish the role of a connection. Accepted values aremaster
,slave
and, for redis-sentinel,sentinel
. This led to a redesign of how connections
can be retrieved from replication backends: the method getConnectionById() now
retrieves a connection only by its ID (ip:port pair), to get a connection by
its alias there is the new method getConnectionByAlias(). This method is not
supported by the redis-sentinel backend due to its dynamic nature (connections
are retrieved and initialized at runtime from sentinels) but it is possible to
get a single connection from the pool by using its ID. It is also possible to
retrive a connection by role using the method getConnectionByRole(). -
The concept of connection ID (ip:port pair) and connection alias (the
alias
parameter) inPredis\Connection\Cluster\PredisCluster
has been separated.
This change does not affect distribution and it is safe for existing clusters. -
Client option classes now live in the
Predis\Configuration\Option
namespace. -
Classes for Redis commands have been moved into the new
Predis\Command\Redis
namespace and each class name mirrors the respective Redis command ID. -
The concept of server profiles is gone, the library now uses a single command
factory to create instances of commands classes. Theprofile
option has been
replaced by thecommands
option acceptingPredis\Command\FactoryInterface
to customize the underlying command factory. The default command factory class
used by Predis isPredis\Command\RedisFactory
and it still allows developers
to define or override commands with their own implementations. In addition to
that,Predis\Command\RedisFactory
relies on a convention-over-configuration
approach by looking for a suitable class with the same name as the command ID
in thePredis\Command\Redis
when the internal class map does not contain a
class associated. -
The method
Predis\Client::getClientFor($connectionID)
has been replaced by
getClientBy($selector, $value, $callable = null)
which is more flexible as
it is not limited to picking a connection from the underlying replication or
cluster backend by ID, but allows users to specify a$selector
that can be
eitherid
(the old behavior),key
,slot
orcommand
. The client uses
duck-typing instead of type-checking to verify that the underlying connection
implements a method that matches the specified selector which means that some
selectors may not be available to all kinds of connection backends. -
The method
Predis\Client::getConnectionById($connectionID)
has been removed. -
Changed the signature for the constructor of
Predis\Command\RawCommand
. -
The
Predis\Connection\Aggregate
namespace has been split into two separate
namespaces for cluster backends (Predis\Connection\Cluster
) and replication
backends (Predis\Connection\Replication
). -
The method
Predis\Connection\AggregateConnectionInterface::getConnection()
has been renamed togetConnectionByCommand()
. -
The methods
switchToMaster()
andswitchToSlave()
have been promoted to be
part ofPredis\Connection\Replication\ReplicationInterface
while the method
switchTo($connection)
has been removed from it. -
The method
Predis\Connection\Cluster\PredisCluster::executeCommandOnNodes()
has been removed as it is possible to achieve the same by iterating over the
connection or, even better, over the client instance in order to execute the
same command against all of the registered connections. -
The class
Predis\CommunicationException
now uses the correct default types
for the$message
(string) and$code
(integer) parameters. -
The method
onConnectionError()
inPredis\Connection\AbstractConnection
class now passes the second argument as an integer value0
as its default
value instead ofnull
. -
Support Pub/Sub and Pipelines when using replication
-
The class
Predis\Transaction\AbortedMultiExecException
now uses the correct
default types for the$code
(integer) parameter. -
FIX: using
strval
ingetScanOptions()
method, part of
Predis\Collection\Iterator\CursorBasedIterator
to make sure we retrieve the
string value of$this->match
and not passingnull
tostrlen()
function. -
FIX: the value returned from
getArgument()
inisReadOperation()
method,
part ofPredis\Replication\ReplicationStrategy
class, is checked to not pass
null
tosha1
function. -
FIX: the value returned from
getArgument()
inparseResponse()
method,
part ofPredis\Command\Redis\SENTINEL
class, is checked to not passnull
tostrtolower()
function.
