Tim seems to have a great lock-free FIFO implementation, although I see that it uses a GPL license rather than Boost. Any chance we could convince you to change the license, Tim? (nudge, nudge, wink, wink) =)
i would consider to change the license for my fifo implementation to a boost-style license, if there would be a demand to use it for a boost.lockfree library ... however there might be some issues, though ... - i am not sure, whether the algorithm for memory reclamation is patented, i am not a lawyer, nor do i know of the legal status of american software patents in europe ... i somewhere read that maged michael's hazard pointers are patented, not sure about the pass-the-buck algorithm, that i used - if the algorithm is patented, i hope, the holder won't sue a developer of a gpl implementation - there are no boost/c++-style atomic operations, something like an implementation of n2427 ... ... as long as these issues are not resolved, i prefer a gpl license :) i would like to see a boost.lockfree library, with building blocks for lockfree containers (atomic primitives, aba-safe smart pointers, memory reclamation schemes, ...), several containers (queue, set, ...) and a lock-free reference counting smart pointer class (afaict, boost's smart pointer classes are not thread-safe) ... of course it would be wonderful to have both dynamic-sized and fized- sized containers, which can be used in hard real-time systems ... cheers, tim -- tim@klingt.org http://tim.klingt.org I must say I find television very educational.
