621
6222011-06-13 Userspace RCU 0.6.2
623 * Fix build on powerpc.
624
6252011-06-13 Userspace RCU 0.6.1
626 * Add missing headers into release tarball:
627 urcu-call-rcu-impl.h and urcu-defer-impl.h
628
6292011-06-10 Userspace RCU 0.6.0
630 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
631 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
632 into a single .so: liburcu-cds.so to have a single header/shared
633 object holding all concurrency-aware data containers. It provides
634 support for RCU lists, queues and stacks at the moment.
635 * liburcu 0.6.0 now allows linking a single application with multiple
636 flavors of RCU. This required a library API change which is
637 incompatible with older 0.5.x liburcu. The .so version number
638 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
639 * Added "atfork" handling API, documented in README. Only useful for
640 processes using fork() without following exec().
641 * Renaming the following files, keeping the old files (producing a
642 compiler warning):
643 urcu/uatomic_arch.h -> urcu/uatomic.h
644 urcu/urcu-futex.h -> urcu/futex.h
645 urcu/urcu_ref.h -> urcu/ref.h
646
6472011-03-04 Userspace RCU 0.5.4
648 * urcu-bp: Update fork() handling
649
650 Introduce
651
652 extern void rcu_bp_before_fork(void);
653 extern void rcu_bp_after_fork_parent(void);
654 extern void rcu_bp_after_fork_child(void);
655
656 to handle fork gracefully. These disable signals and hold
657 the registry mutex across forks. (this flavor of the liburcu
658 library ("bp" for "bulletproof") is mainly used by UST, the
659 user-space tracer).
660
6612011-03-03 Userspace RCU 0.5.3
662 * Add support for older ARM single-CPU architecturess (pre-ARMv7)
663 (thanks to Jason Wessel from WindRiver).
664 * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier).
665 * Remove leftover list_t type from urcu/list.h (namespace cleanup).
666 * urcu_defer: handle malloc error value.
667 * Update README file to describe urcu interaction with fork() when not
668 * followed
669 by an exec() system call.
670
6712010-11-18 Userspace RCU 0.5.2
672 * Fix renaming error introduced in 0.5.0.
673
6742010-11-18 Userspace RCU 0.5.1
675 * Fix renaming error introduced in 0.5.0. (incomplete fix)
676
6772010-11-18 Userspace RCU 0.5.0
678 * Version 0.5.0 changes the API presented by memory model,
679 architecture abstraction and data structure primitives in
680 headers. The prefixes are, respectively:
681 - cmm_ : Concurrent Memory Model
682 - caa_ : Concurrent Architecture Abstraction
683 - cds_ : Concurrent Data Structures
684
6852010-03-04 Userspace RCU 0.4.2
686 * Add generic uatomic ops support.
687 * Bugfix in urcu-bp. (rare garbage collection bug occurring in

689
6902010-02-12 Userspace RCU 0.4.1
691 * s390: compilation fix.
692
6932010-01-30 Userspace RCU 0.4.0
694 * API change: SIGURCU -> SIGRCU
695 * API changes: standardize on rcu_ prefix.
696 * API change: urcu_init -> rcu_init.
697 * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
698 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
699 ((moving from URCU -> RCU).
700 * library names changes: liburcu becomes the "default" version, using
701 sys_membarrier() when available, and using liburcu-mb as a
702 fallback.
703 * The signal-based liburcu is renamed from liburcu to
704 liburcu-signal. People previously using the signal-based
705 "liburcu" will automatically be moved to the "default" liburcu
706 version.
707
7082009-11-16 Userspace RCU 0.3.1
709 * Add support for sparcv9 32-bit build.

725

727 * small header dependency fix for rculist.h.
728 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
729 the UST userspace tracer. It's a library that sacrifices a bit
730 of read-side performance for automatically monitoring thread
731 creation/removal. See README for details.
732
7332009-10-01 Userspace RCU 0.2
734 * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
735 rcu_set_pointer.
