612 | * Add missing headers into release tarball: | |
613 | urcu-call-rcu-impl.h and urcu-defer-impl.h | |
614 | ||
615 | 2011-06-10 Userspace RCU 0.6.0 | |
616 | * Added call_rcu() support, graciously contributed by Paul E. McKenney. | |
617 | * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS) | |
618 | into a single .so: liburcu-cds.so to have a single header/shared | |
619 | object holding all concurrency-aware data containers. It provides | |
620 | support for RCU lists, queues and stacks at the moment. | |
621 | * liburcu 0.6.0 now allows linking a single application with multiple | |
622 | flavors of RCU. This required a library API change which is | |
623 | incompatible with older 0.5.x liburcu. The .so version number | |
624 | is therefore bumped from 0 to 1 (e.g. liburcu.so.1). | |
625 | * Added "atfork" handling API, documented in README. Only useful for | |
626 | processes using fork() without following exec(). | |
627 | * Renaming the following files, keeping the old files (producing a | |
628 | compiler warning): | |
629 | urcu/uatomic_arch.h -> urcu/uatomic.h | |
630 | urcu/urcu-futex.h -> urcu/futex.h | |
631 | urcu/urcu_ref.h -> urcu/ref.h | |

637 | ||
638 | extern void rcu_bp_before_fork(void); | |
639 | extern void rcu_bp_after_fork_parent(void); | |
640 | extern void rcu_bp_after_fork_child(void); | |
641 | ||
642 | to handle fork gracefully. These disable signals and hold | |
643 | the registry mutex across forks. (this flavor of the liburcu | |
644 | library ("bp" for "bulletproof") is mainly used by UST, the | |
645 | user-space tracer). | |
646 | ||
647 | 2011-03-03 Userspace RCU 0.5.3 | |
648 | * Add support for older ARM single-CPU architecturess (pre-ARMv7) | |
649 | (thanks to Jason Wessel from WindRiver). | |

651 | * Remove leftover list_t type from urcu/list.h (namespace cleanup). | |
652 | * urcu_defer: handle malloc error value. | |
653 | * Update README file to describe urcu interaction with fork() when not | |
654 | * followed | |
655 | by an exec() system call. | |
656 | ||

662 | ||
663 | 2010-11-18 Userspace RCU 0.5.0 | |
664 | * Version 0.5.0 changes the API presented by memory model, | |
665 | architecture abstraction and data structure primitives in | |
666 | headers. The prefixes are, respectively: | |
667 | - cmm_ : Concurrent Memory Model | |
668 | - caa_ : Concurrent Architecture Abstraction | |
669 | - cds_ : Concurrent Data Structures | |
670 | ||
671 | 2010-03-04 Userspace RCU 0.4.2 | |

674 | multithreaded environment). Only affects urcu-bp users (UST). | |
675 | ||

680 | * API change: SIGURCU -> SIGRCU | |
681 | * API changes: standardize on rcu_ prefix. | |
682 | * API change: urcu_init -> rcu_init. | |
683 | * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE, | |
684 | CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH. | |
685 | ((moving from URCU -> RCU). | |
686 | * library names changes: liburcu becomes the "default" version, using | |
687 | sys_membarrier() when available, and using liburcu-mb as a | |
688 | fallback. | |
689 | * The signal-based liburcu is renamed from liburcu to | |
690 | liburcu-signal. People previously using the signal-based | |
691 | "liburcu" will automatically be moved to the "default" liburcu | |
692 | version. | |
693 | ||
694 | 2009-11-16 Userspace RCU 0.3.1 | |

710 | * Adds type checking to urcu-pointer.h pointer exchange primitives. | |
711 | ||
712 | 2009-10-02 Userspace RCU 0.2.1 | |
713 | * small header dependency fix for rculist.h. | |
714 | * new "liburcu-bp.so" : "Bulletproof RCU", made especially for | |
715 | the UST userspace tracer. It's a library that sacrifices a bit | |
716 | of read-side performance for automatically monitoring thread | |
717 | creation/removal. See README for details. | |
718 | ||
719 | 2009-10-01 Userspace RCU 0.2 | |
