This data synchronization library provides read-side access which scales linearly with the number of cores. It does so by allowing multiples copies of a given data structure to live at the same time, and by monitoring the data structure accesses to detect grace periods after which memory reclamation is possible. Changelog: - Added call_rcu() support, graciously contributed by Paul E. McKenney. - Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS) into a single .so: liburcu-cds.so to have a single header/shared object holding all concurrency-aware data containers. It provides support for RCU lists, queues and stacks at the moment. - liburcu 0.6.0 now allows linking a single application with multiple flavors of RCU. This required a library API change which is incompatible with older 0.5.x liburcu. The .so version number is therefore bumped from 0 to 1 (e.g. liburcu.so.1). - Added "atfork" handling API, documented in README. Only useful for processes using fork() without following exec(). - Renaming the following files, keeping the old files (producing a compiler warning): urcu/uatomic_arch.h -> urcu/uatomic.h urcu/urcu-futex.h -> urcu/futex.h urcu/urcu_ref.h -> urcu/ref.h Project website: http://lttng.org/urcu Download link: http://www.lttng.org/files/urcu/ -- Mathieu Desnoyers Operating System Efficiency R&D Consultant EfficiOS Inc. http://www.efficios.com
