2010-06-09Channel: Callbacks reviewed - they are now part of Subclasses of the default ↵Sebastian Thiel
channel implementation, one of which is used as base by the Pool Read channel, releasing it of the duty to call these itself. The write channel with callback subclass allows the transformation of the item to be written
2010-06-09Channel: removed pseudoconstructor, which clearly improves the design and ↵Sebastian Thiel
makes it easier to constomize pool: in serial mode, created channels will be serial-only, which brings 15% of performance
2010-06-09Channel: Read method revised - now it really really doesn't block anymore, ↵Sebastian Thiel
and it runs faster as well, about 2/3 of the performance we have when being in serial mode
2010-06-08Its getting better already - intermediate commit before further chaning the ↵Sebastian Thiel
task class
2010-06-08The new channeldesign actually works, but it also shows that its located at ↵Sebastian Thiel
the wrong spot. The channel is nothing more than an adapter allowing to read multiple items from a thread-safe queue, the queue itself though must be 'closable' for writing, or needs something like a writable flag.
2010-06-07pool.consumed_tasks: is now a queue to be thread safe, in preparation for ↵Sebastian Thiel
multiple connected pools Reduced waiting time in tests to make them complete faster
2010-06-06channel.read: enhanced to be sure we don't run into non-atomicity issues ↵Sebastian Thiel
related to our channel closed flag, which is the only way not to block forever on read(0) channels which were closed by a thread 'in the meanwhile'
2010-06-06Improved pool design and started rough implementation, top down to learn ↵Sebastian Thiel
while going. Tests will be written soon for verification, its still quite theoretical
2010-06-05Renamed mp to async, as this is a much better name for what is actually ↵Sebastian Thiel
going on. The default implementation uses threads, which ends up being nothing more than async, as they are all locked down by internal and the global interpreter lock
