506 2011-07-21 Userspace RCU 0.6.4
507 * uatomic: Fix ARM build errors in uatomic.
508 * urcu tests: hold mutex across use of custom allocator.
509 * Portability fixes to support FreeBSD 8.2.
511 2011-06-27 Userspace RCU 0.6.3
512 * uatomic: Fix i386 compatibility build errors in uatomic.
514 2011-06-13 Userspace RCU 0.6.2
515 * Fix build on powerpc.
517 2011-06-13 Userspace RCU 0.6.1
518 * Add missing headers into release tarball:
519 urcu-call-rcu-impl.h and urcu-defer-impl.h
521 2011-06-10 Userspace RCU 0.6.0
522 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
523 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
524 into a single .so: liburcu-cds.so to have a single header/shared
525 object holding all concurrency-aware data containers. It provides
526 support for RCU lists, queues and stacks at the moment.
527 * liburcu 0.6.0 now allows linking a single application with multiple
528 flavors of RCU. This required a library API change which is
529 incompatible with older 0.5.x liburcu. The .so version number
530 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
531 * Added "atfork" handling API, documented in README. Only useful for
532 processes using fork() without following exec().
533 * Renaming the following files, keeping the old files (producing a
535 urcu/uatomic_arch.h -> urcu/uatomic.h
536 urcu/urcu-futex.h -> urcu/futex.h
537 urcu/urcu_ref.h -> urcu/ref.h
539 2011-03-04 Userspace RCU 0.5.4
540 * urcu-bp: Update fork() handling
544 extern void rcu_bp_before_fork(void);
545 extern void rcu_bp_after_fork_parent(void);
546 extern void rcu_bp_after_fork_child(void);
548 to handle fork gracefully. These disable signals and hold
549 the registry mutex across forks. (this flavor of the liburcu
550 library ("bp" for "bulletproof") is mainly used by UST, the
553 2011-03-03 Userspace RCU 0.5.3
554 * Add support for older ARM single-CPU architecturess (pre-ARMv7)
555 (thanks to Jason Wessel from WindRiver).
556 * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier).
557 * Remove leftover list_t type from urcu/list.h (namespace cleanup).
558 * urcu_defer: handle malloc error value.
559 * Update README file to describe urcu interaction with fork() when not
561 by an exec() system call.
563 2010-11-18 Userspace RCU 0.5.2
564 * Fix renaming error introduced in 0.5.0.
566 2010-11-18 Userspace RCU 0.5.1
567 * Fix renaming error introduced in 0.5.0. (incomplete fix)
569 2010-11-18 Userspace RCU 0.5.0
570 * Version 0.5.0 changes the API presented by memory model,
571 architecture abstraction and data structure primitives in
572 headers. The prefixes are, respectively:
573 - cmm_ : Concurrent Memory Model
574 - caa_ : Concurrent Architecture Abstraction
575 - cds_ : Concurrent Data Structures
577 2010-03-04 Userspace RCU 0.4.2
578 * Add generic uatomic ops support.
579 * Bugfix in urcu-bp. (rare garbage collection bug occurring in
580 multithreaded environment). Only affects urcu-bp users (UST).
582 2010-02-12 Userspace RCU 0.4.1
583 * s390: compilation fix.
585 2010-01-30 Userspace RCU 0.4.0
586 * API change: SIGURCU -> SIGRCU
587 * API changes: standardize on rcu_ prefix.
588 * API change: urcu_init -> rcu_init.
589 * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
590 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
591 ((moving from URCU -> RCU).
592 * library names changes: liburcu becomes the "default" version, using
593 sys_membarrier() when available, and using liburcu-mb as a
595 * The signal-based liburcu is renamed from liburcu to
596 liburcu-signal. People previously using the signal-based
597 "liburcu" will automatically be moved to the "default" liburcu
600 2009-11-16 Userspace RCU 0.3.1
601 * Add support for sparcv9 32-bit build.
602 * Update build system to use --host instead of --target.
604 2009-11-03 Userspace RCU 0.3.0
605 * API change for the "deferred work" interface.
607 2009-10-14 Userspace RCU 0.2.3
609 * Automated architecture detection, with i386 fallback.
610 * Detect if NR_futex is on the system, fallback on portable
612 * Add configure mode for UP-only systems.
614 2009-10-02 Userspace RCU 0.2.2
615 * Phases out rcu_publish_content() api.
616 * Adds type checking to urcu-pointer.h pointer exchange primitives.
618 2009-10-02 Userspace RCU 0.2.1
619 * small header dependency fix for rculist.h.
620 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
621 the UST userspace tracer. It's a library that sacrifices a bit
622 of read-side performance for automatically monitoring thread
623 creation/removal. See README for details.
625 2009-10-01 Userspace RCU 0.2
626 * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
