Similarly to the socket-ext based connection using phpiredis, in our
stream based PhpiredisStreamConnection class we should read data from
the stream using stream_socket_recvfrom() instead of fread() because
the latter could block until a timeout is reached when the read buffer
contains less data then the specified length.
IMPORTANT: stream_socket_recvfrom() bypasses stream wrappers which
means that TLS/SSL, as requested by PR #158, won't ever work with
this connection class as the function returns the original encrypted
bytes.
This commit fixes issue #180.
This is more consistent with the actual purpose of this method and
more in-line with a possible future change in the underlying command
used to retrieve the slots map if redis-cluster will implement the
CLUSTER SLOTS command.
* 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.
Issue #151 pointed to a flaw in how command instances were converted
to strings: we were simply truncating their arguments when exceeding
a certain size as this was mostly intended for logging or debugging,
but this approach breaks strings containing multibyte characters so
we decided to drop this feature altogether for the sake of simplicity.
It is still possible to replicate the same (and eventually improved)
behavior externally by fetching ID and arguments of a command out of
a command instance using the public methods made available by the
Predis\Command\CommandInterface.
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.
Multi-keys operations are not allowed even when keys generate the same
hash but this will probably be supported in later betas of Redis which
means we will basically end up reusing the whole strategy used for
client-side sharding.
Ported from the v0.8 branch.
This actually makes sense since whatever the actual implementation is,
classes implementing these interfaces should provide at least those
properties that are actively used through the library.
Bug was not severe since +QUEUED status responses were returned anyway
but they were not cached as expected. We added a test in the suite.
This fixes#142.
The base abstract connection class now returns a bool to indicate when
the actual connect() operation has been performed on the underlying
resource. This return value is not part of the interface so extending
classes can decide to not return any value.
Achieving compatibility actually required a few marginal changes:
- HHVM still has some issues with re-entrant calls to __get(). The
applied change is an hack simply because it is ugly, but it is not
wrong and does not break the signature of the options interface.
- Since we cannot rely on the PHP version to detect the availability
of socket_import_stream(), we switched to function_exists(). As an
added bonus, using function_exists() is twice faster.
- In the test suite we removed an assertion for the message of an
E_WARNING simply because HHVM emits a different message. Checking
for the warning is actually enough in that context.
While the whole test suite passes on HHVM 2.3.0, please remember that
HHVM is still in development and things could break anytime especially
in some obscure corner cases.
