Using SplQueue instead of a plain PHP array to queue command instance in
the pipeline is faster and makes the underlying implementation definitely
more clean.
This change is not going to be backported to Predis v0.7 due to changes
in Predis\Pipeline\PipelineContextInterface.
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.
The actual code to switch to master has been implemented only in the
standard and the fire-and-forget executor classes since it does not
make sense to have it in special executors used exclusively when in
client-side clustering mode.
This is a starting point to add a documentation of the whole set of APIs and
classes of Predis. The next step will be to actually improve and extend it.
