495 | * uatomic: Fix i386 compatibility build errors in uatomic. | |
496 | ||
497 | 2011-06-13 Userspace RCU 0.6.2 | |
498 | * Fix build on powerpc. | |
499 | ||
500 | 2011-06-13 Userspace RCU 0.6.1 | |
501 | * Add missing headers into release tarball: | |
502 | urcu-call-rcu-impl.h and urcu-defer-impl.h | |
503 | ||
504 | 2011-06-10 Userspace RCU 0.6.0 | |
505 | * Added call_rcu() support, graciously contributed by Paul E. McKenney. | |
506 | * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS) | |
507 | into a single .so: liburcu-cds.so to have a single header/shared | |
508 | object holding all concurrency-aware data containers. It provides | |
509 | support for RCU lists, queues and stacks at the moment. | |
510 | * liburcu 0.6.0 now allows linking a single application with multiple | |
511 | flavors of RCU. This required a library API change which is | |
512 | incompatible with older 0.5.x liburcu. The .so version number | |
513 | is therefore bumped from 0 to 1 (e.g. liburcu.so.1). | |
514 | * Added "atfork" handling API, documented in README. Only useful for | |
515 | processes using fork() without following exec(). | |
516 | * Renaming the following files, keeping the old files (producing a | |
517 | compiler warning): | |
518 | urcu/uatomic_arch.h -> urcu/uatomic.h | |
519 | urcu/urcu-futex.h -> urcu/futex.h | |
520 | urcu/urcu_ref.h -> urcu/ref.h | |
521 | ||
522 | 2011-03-04 Userspace RCU 0.5.4 | |
523 | * urcu-bp: Update fork() handling | |
524 | ||
525 | Introduce | |
526 | ||
527 | extern void rcu_bp_before_fork(void); | |
528 | extern void rcu_bp_after_fork_parent(void); | |
529 | extern void rcu_bp_after_fork_child(void); | |
530 | ||
531 | to handle fork gracefully. These disable signals and hold | |
532 | the registry mutex across forks. (this flavor of the liburcu | |
533 | library ("bp" for "bulletproof") is mainly used by UST, the | |
534 | user-space tracer). | |
535 | ||
536 | 2011-03-03 Userspace RCU 0.5.3 | |
537 | * Add support for older ARM single-CPU architecturess (pre-ARMv7) | |
538 | (thanks to Jason Wessel from WindRiver). | |
539 | * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier). | |
540 | * Remove leftover list_t type from urcu/list.h (namespace cleanup). | |
541 | * urcu_defer: handle malloc error value. | |
542 | * Update README file to describe urcu interaction with fork() when not | |
543 | * followed | |
544 | by an exec() system call. | |
545 | ||
546 | 2010-11-18 Userspace RCU 0.5.2 | |
547 | * Fix renaming error introduced in 0.5.0. | |
548 | ||
549 | 2010-11-18 Userspace RCU 0.5.1 | |
550 | * Fix renaming error introduced in 0.5.0. (incomplete fix) | |
551 | ||
552 | 2010-11-18 Userspace RCU 0.5.0 | |
553 | * Version 0.5.0 changes the API presented by memory model, | |
554 | architecture abstraction and data structure primitives in | |
555 | headers. The prefixes are, respectively: | |
556 | - cmm_ : Concurrent Memory Model | |
557 | - caa_ : Concurrent Architecture Abstraction | |
558 | - cds_ : Concurrent Data Structures | |
559 | ||
560 | 2010-03-04 Userspace RCU 0.4.2 | |
561 | * Add generic uatomic ops support. | |
562 | * Bugfix in urcu-bp. (rare garbage collection bug occurring in | |
563 | multithreaded environment). Only affects urcu-bp users (UST). | |
564 | ||
565 | 2010-02-12 Userspace RCU 0.4.1 | |
566 | * s390: compilation fix. | |
567 | ||
568 | 2010-01-30 Userspace RCU 0.4.0 | |
569 | * API change: SIGURCU -> SIGRCU | |
570 | * API changes: standardize on rcu_ prefix. | |
571 | * API change: urcu_init -> rcu_init. | |
572 | * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE, | |
573 | CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH. | |
574 | ((moving from URCU -> RCU). | |
575 | * library names changes: liburcu becomes the "default" version, using | |
576 | sys_membarrier() when available, and using liburcu-mb as a | |
577 | fallback. | |
578 | * The signal-based liburcu is renamed from liburcu to | |
579 | liburcu-signal. People previously using the signal-based | |
580 | "liburcu" will automatically be moved to the "default" liburcu | |
581 | version. | |
582 | ||
583 | 2009-11-16 Userspace RCU 0.3.1 | |
584 | * Add support for sparcv9 32-bit build. | |

599 | * Adds type checking to urcu-pointer.h pointer exchange primitives. | |
600 | ||
601 | 2009-10-02 Userspace RCU 0.2.1 | |
602 | * small header dependency fix for rculist.h. | |
603 | * new "liburcu-bp.so" : "Bulletproof RCU", made especially for | |
604 | the UST userspace tracer. It's a library that sacrifices a bit | |
605 | of read-side performance for automatically monitoring thread | |
606 | creation/removal. See README for details. | |
607 | ||
608 | 2009-10-01 Userspace RCU 0.2 | |
609 | * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer, | |
