461 * urcu tests: hold mutex across use of custom allocator.
462 * Portability fixes to support FreeBSD 8.2.
464 2011-06-27 Userspace RCU 0.6.3
465 * uatomic: Fix i386 compatibility build errors in uatomic.
467 2011-06-13 Userspace RCU 0.6.2
468 * Fix build on powerpc.
470 2011-06-13 Userspace RCU 0.6.1
471 * Add missing headers into release tarball:
472 urcu-call-rcu-impl.h and urcu-defer-impl.h
474 2011-06-10 Userspace RCU 0.6.0
475 * Added call_rcu() support, graciously contributed by Paul E. McKenney.
476 * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
477 into a single .so: liburcu-cds.so to have a single header/shared
478 object holding all concurrency-aware data containers. It provides
479 support for RCU lists, queues and stacks at the moment.
480 * liburcu 0.6.0 now allows linking a single application with multiple
481 flavors of RCU. This required a library API change which is
482 incompatible with older 0.5.x liburcu. The .so version number
483 is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
484 * Added "atfork" handling API, documented in README. Only useful for
485 processes using fork() without following exec().
486 * Renaming the following files, keeping the old files (producing a
488 urcu/uatomic_arch.h -> urcu/uatomic.h
489 urcu/urcu-futex.h -> urcu/futex.h
490 urcu/urcu_ref.h -> urcu/ref.h
492 2011-03-04 Userspace RCU 0.5.4
493 * urcu-bp: Update fork() handling
497 extern void rcu_bp_before_fork(void);
498 extern void rcu_bp_after_fork_parent(void);
499 extern void rcu_bp_after_fork_child(void);
501 to handle fork gracefully. These disable signals and hold
502 the registry mutex across forks. (this flavor of the liburcu
503 library ("bp" for "bulletproof") is mainly used by UST, the
506 2011-03-03 Userspace RCU 0.5.3
507 * Add support for older ARM single-CPU architecturess (pre-ARMv7)
508 (thanks to Jason Wessel from WindRiver).
509 * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier).
510 * Remove leftover list_t type from urcu/list.h (namespace cleanup).
511 * urcu_defer: handle malloc error value.
512 * Update README file to describe urcu interaction with fork() when not
514 by an exec() system call.
516 2010-11-18 Userspace RCU 0.5.2
517 * Fix renaming error introduced in 0.5.0.
519 2010-11-18 Userspace RCU 0.5.1
520 * Fix renaming error introduced in 0.5.0. (incomplete fix)
522 2010-11-18 Userspace RCU 0.5.0
523 * Version 0.5.0 changes the API presented by memory model,
524 architecture abstraction and data structure primitives in
525 headers. The prefixes are, respectively:
526 - cmm_ : Concurrent Memory Model
527 - caa_ : Concurrent Architecture Abstraction
528 - cds_ : Concurrent Data Structures
530 2010-03-04 Userspace RCU 0.4.2
531 * Add generic uatomic ops support.
532 * Bugfix in urcu-bp. (rare garbage collection bug occurring in
533 multithreaded environment). Only affects urcu-bp users (UST).
535 2010-02-12 Userspace RCU 0.4.1
536 * s390: compilation fix.
538 2010-01-30 Userspace RCU 0.4.0
539 * API change: SIGURCU -> SIGRCU
540 * API changes: standardize on rcu_ prefix.
541 * API change: urcu_init -> rcu_init.
542 * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
543 CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
544 ((moving from URCU -> RCU).
545 * library names changes: liburcu becomes the "default" version, using
546 sys_membarrier() when available, and using liburcu-mb as a
548 * The signal-based liburcu is renamed from liburcu to
549 liburcu-signal. People previously using the signal-based
550 "liburcu" will automatically be moved to the "default" liburcu
553 2009-11-16 Userspace RCU 0.3.1
554 * Add support for sparcv9 32-bit build.
555 * Update build system to use --host instead of --target.
557 2009-11-03 Userspace RCU 0.3.0
558 * API change for the "deferred work" interface.
560 2009-10-14 Userspace RCU 0.2.3
562 * Automated architecture detection, with i386 fallback.
563 * Detect if NR_futex is on the system, fallback on portable
565 * Add configure mode for UP-only systems.
567 2009-10-02 Userspace RCU 0.2.2
568 * Phases out rcu_publish_content() api.
569 * Adds type checking to urcu-pointer.h pointer exchange primitives.
571 2009-10-02 Userspace RCU 0.2.1
572 * small header dependency fix for rculist.h.
573 * new "liburcu-bp.so" : "Bulletproof RCU", made especially for
574 the UST userspace tracer. It's a library that sacrifices a bit
575 of read-side performance for automatically monitoring thread
576 creation/removal. See README for details.
578 2009-10-01 Userspace RCU 0.2
579 * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
