Commands such as MULTI, EXEC, DISCARD, WATCH and UNWATCH disregard the
the "exceptions" client option and always result in an exception being
thrown on error responses even when the client is configured to return
those errors ("exceptions" set to FALSE).
We also changed some options for this class, the accepted ones are:
- "keys": string or array of strings for automatic WATCH.
- "cas": sets the check-and-set mode.
- "retry": number of attempts before giving up aborted transactions.
- "exceptions": sets whether exceptions should be thrown on error
responses (overrides the "exceptions" client option).
The "on_retry" option has been removed.
The Predis\Transaction\MultiExecState class is actually quite dummy as
it does not work as a finite-state machine, but is used to track state
using flags. It basically replicates the same behaviour of when it was
part of the Predis\Transaction\MultiExec code and it will do for now.
The "throw_errors" connection parameter has been removed and replaced by the
new "exceptions" client option since exceptions on -ERR replies returned by
Redis are not generated by connection classes anymore but are thrown by the
client class and other abstractions such as pipeline contexts.
This change does not affect much people using the Predis\Client class (aside
from the different configuration) but gives much more flexibility to those
building their own pieces of code around the internal classes of Predis.
Fix also a few bugs found while rewriting the test suite.
In order to be able to run integration tests, the test suite requires
a version of Redis >= 2.4.0.
The units have been splitted into several different groups using
PHPUnit @group annotation to allow developers to enable, disable
and combine certain types of tests. The available groups are:
- disconnected: can run without a Redis server online
- connected: active connection to a Redis server is required
- commands: test dedicated to a specific Redis command
- slow: performs operations that can slow down execution;
A list of the available groups can be obtained by running
phpunit --list-groups
Groups of tests can be disabled or enabled via the XML configuration
file or the standard command-line test runner. Please note that due
to a bug in PHPUnit, older versions ignore the --group option when
the group is excluded in the XML configuration file. Please refer to
http://github.com/sebastianbergmann/phpunit/issues/320 for details
Integration tests in the @connected group check if the command being
tested is defined in the selected server profile (see the value of
the TEST_SERVER_VERSION constant in phpunit.xml). If the command is
not defined in the target server profile, the integration test is
automatically marked as skipped.
We also provide an helper script in the bin directory that can be
used to automatically generate a file with the scheleton of a test
case for a Redis command by specifying the name of the class in the
Predis\Commands namespace. For example, to generate a test case for
SET (represented by the Predis\Commands\StringSet class):
./bin/generate-command-test.php --class=StringSet
The realm of a command is automatically inferred from the name of the
class, but it can be set using the --realm option.
