| 547 | * uatomic: Fix ARM build errors in uatomic. |
| 548 | * urcu tests: hold mutex across use of custom allocator. |
| 549 | * Portability fixes to support FreeBSD 8.2. |
| 550 | |
| 551 | 2011-06-27 Userspace RCU 0.6.3 |
| 552 | * uatomic: Fix i386 compatibility build errors in uatomic. |
| 553 | |
| 554 | 2011-06-13 Userspace RCU 0.6.2 |
| 555 | * Fix build on powerpc. |
| 556 | |
| 557 | 2011-06-13 Userspace RCU 0.6.1 |
| 558 | * Add missing headers into release tarball: |
| 559 | urcu-call-rcu-impl.h and urcu-defer-impl.h |
| 560 | |
| 561 | 2011-06-10 Userspace RCU 0.6.0 |
| 562 | * Added call_rcu() support, graciously contributed by Paul E. McKenney. |
| 563 | * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS) |
| 564 | into a single .so: liburcu-cds.so to have a single header/shared |
| 565 | object holding all concurrency-aware data containers. It provides |
| 566 | support for RCU lists, queues and stacks at the moment. |
| 567 | * liburcu 0.6.0 now allows linking a single application with multiple |
| 568 | flavors of RCU. This required a library API change which is |
| 569 | incompatible with older 0.5.x liburcu. The .so version number |
| 570 | is therefore bumped from 0 to 1 (e.g. liburcu.so.1). |
| 571 | * Added "atfork" handling API, documented in README. Only useful for |
| 572 | processes using fork() without following exec(). |
| 573 | * Renaming the following files, keeping the old files (producing a |
| 574 | compiler warning): |
| 575 | urcu/uatomic_arch.h -> urcu/uatomic.h |
| 576 | urcu/urcu-futex.h -> urcu/futex.h |
| 577 | urcu/urcu_ref.h -> urcu/ref.h |
| 578 | |
| 579 | 2011-03-04 Userspace RCU 0.5.4 |
| 580 | * urcu-bp: Update fork() handling |
| 581 | |
| 582 | Introduce |
| 583 | |
| 584 | extern void rcu_bp_before_fork(void); |
| 585 | extern void rcu_bp_after_fork_parent(void); |
| 586 | extern void rcu_bp_after_fork_child(void); |
| 587 | |
| 588 | to handle fork gracefully. These disable signals and hold |
| 589 | the registry mutex across forks. (this flavor of the liburcu |
| 590 | library ("bp" for "bulletproof") is mainly used by UST, the |
| 591 | user-space tracer). |
| 592 | |
| 593 | 2011-03-03 Userspace RCU 0.5.3 |
| 594 | * Add support for older ARM single-CPU architecturess (pre-ARMv7) |
| 595 | (thanks to Jason Wessel from WindRiver). |
| 596 | * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier). |
| 597 | * Remove leftover list_t type from urcu/list.h (namespace cleanup). |
| 598 | * urcu_defer: handle malloc error value. |
| 599 | * Update README file to describe urcu interaction with fork() when not |
| 600 | * followed |
| 601 | by an exec() system call. |
| 602 | |
| 603 | 2010-11-18 Userspace RCU 0.5.2 |
| 604 | * Fix renaming error introduced in 0.5.0. |
| 605 | |
| 606 | 2010-11-18 Userspace RCU 0.5.1 |
| 607 | * Fix renaming error introduced in 0.5.0. (incomplete fix) |
| 608 | |
| 609 | 2010-11-18 Userspace RCU 0.5.0 |
| 610 | * Version 0.5.0 changes the API presented by memory model, |
| 611 | architecture abstraction and data structure primitives in |
| 612 | headers. The prefixes are, respectively: |
| 613 | - cmm_ : Concurrent Memory Model |
| 614 | - caa_ : Concurrent Architecture Abstraction |
| 615 | - cds_ : Concurrent Data Structures |
| 616 | |
| 617 | 2010-03-04 Userspace RCU 0.4.2 |
| 618 | * Add generic uatomic ops support. |
| 619 | * Bugfix in urcu-bp. (rare garbage collection bug occurring in |
| 620 | multithreaded environment). Only affects urcu-bp users (UST). |
| 621 | |
| 622 | 2010-02-12 Userspace RCU 0.4.1 |
| 623 | * s390: compilation fix. |
| 624 | |
| 625 | 2010-01-30 Userspace RCU 0.4.0 |
| 626 | * API change: SIGURCU -> SIGRCU |
| 627 | * API changes: standardize on rcu_ prefix. |
| 628 | * API change: urcu_init -> rcu_init. |
| 629 | * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE, |
| 630 | CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH. |
| 631 | ((moving from URCU -> RCU). |
| 632 | * library names changes: liburcu becomes the "default" version, using |
| 633 | sys_membarrier() when available, and using liburcu-mb as a |
| 634 | fallback. |
| 635 | * The signal-based liburcu is renamed from liburcu to |
| 636 | liburcu-signal. People previously using the signal-based |
| 637 | "liburcu" will automatically be moved to the "default" liburcu |
| 638 | version. |
| 639 | |
| 640 | 2009-11-16 Userspace RCU 0.3.1 |
| 641 | * Add support for sparcv9 32-bit build. |
| 642 | * Update build system to use --host instead of --target. |
| 643 | |
| 644 | 2009-11-03 Userspace RCU 0.3.0 |

| 653 | |
| 654 | 2009-10-02 Userspace RCU 0.2.2 |
| 655 | * Phases out rcu_publish_content() api. |
| 656 | * Adds type checking to urcu-pointer.h pointer exchange primitives. |
| 657 | |
| 658 | 2009-10-02 Userspace RCU 0.2.1 |
| 659 | * small header dependency fix for rculist.h. |
| 660 | * new "liburcu-bp.so" : "Bulletproof RCU", made especially for |
| 661 | the UST userspace tracer. It's a library that sacrifices a bit |
| 662 | of read-side performance for automatically monitoring thread |
| 663 | creation/removal. See README for details. |
| 664 | |
| 665 | 2009-10-01 Userspace RCU 0.2 |
| 666 | * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer, |
| 667 | rcu_set_pointer. |
| 668 | |

| 670 | * Initial release. |
