442 | 2011-07-21 Userspace RCU 0.6.4 |
| 443 | * uatomic: Fix ARM build errors in uatomic. | |
| 444 | * urcu tests: hold mutex across use of custom allocator. | |
| 445 | * Portability fixes to support FreeBSD 8.2. | |
| 446 | ||
| aa120cd0 MD |
447 | 2011-06-27 Userspace RCU 0.6.3 |
| 448 | * uatomic: Fix i386 compatibility build errors in uatomic. | |
| 449 | ||
| 450 | 2011-06-13 Userspace RCU 0.6.2 | |
| 451 | * Fix build on powerpc. | |
| 452 | ||
| 453 | 2011-06-13 Userspace RCU 0.6.1 | |
| 454 | * Add missing headers into release tarball: | |
| 455 | urcu-call-rcu-impl.h and urcu-defer-impl.h | |
| 456 | ||
| 457 | 2011-06-10 Userspace RCU 0.6.0 | |
| 458 | * Added call_rcu() support, graciously contributed by Paul E. McKenney. | |
| 459 | * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS) | |
| 460 | into a single .so: liburcu-cds.so to have a single header/shared | |
| 461 | object holding all concurrency-aware data containers. It provides | |
| 462 | support for RCU lists, queues and stacks at the moment. | |
| 463 | * liburcu 0.6.0 now allows linking a single application with multiple | |
| 464 | flavors of RCU. This required a library API change which is | |
| 465 | incompatible with older 0.5.x liburcu. The .so version number | |
| 466 | is therefore bumped from 0 to 1 (e.g. liburcu.so.1). | |
| 467 | * Added "atfork" handling API, documented in README. Only useful for | |
| 468 | processes using fork() without following exec(). | |
| 469 | * Renaming the following files, keeping the old files (producing a | |
| 470 | compiler warning): | |
| 471 | urcu/uatomic_arch.h -> urcu/uatomic.h | |
| 472 | urcu/urcu-futex.h -> urcu/futex.h | |
| 473 | urcu/urcu_ref.h -> urcu/ref.h | |
| 474 | ||
| 475 | 2011-03-04 Userspace RCU 0.5.4 | |
| 476 | * urcu-bp: Update fork() handling | |
| 477 | ||
| 478 | Introduce | |
| 479 | ||
| 480 | extern void rcu_bp_before_fork(void); | |
| 481 | extern void rcu_bp_after_fork_parent(void); | |
| 482 | extern void rcu_bp_after_fork_child(void); | |
| 483 | ||
| 484 | to handle fork gracefully. These disable signals and hold | |
| 485 | the registry mutex across forks. (this flavor of the liburcu | |
| 486 | library ("bp" for "bulletproof") is mainly used by UST, the | |
| 487 | user-space tracer). | |
| 488 | ||
| 489 | 2011-03-03 Userspace RCU 0.5.3 | |
| 490 | * Add support for older ARM single-CPU architecturess (pre-ARMv7) | |
| 491 | (thanks to Jason Wessel from WindRiver). | |
| 492 | * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier). | |
| 493 | * Remove leftover list_t type from urcu/list.h (namespace cleanup). | |
| 494 | * urcu_defer: handle malloc error value. | |
| 495 | * Update README file to describe urcu interaction with fork() when not | |
| 496 | * followed | |
| 497 | by an exec() system call. | |
| 498 | ||
| 499 | 2010-11-18 Userspace RCU 0.5.2 | |
| 500 | * Fix renaming error introduced in 0.5.0. | |
| 501 | ||
| 502 | 2010-11-18 Userspace RCU 0.5.1 | |
| 503 | * Fix renaming error introduced in 0.5.0. (incomplete fix) | |
| 504 | ||
| 505 | 2010-11-18 Userspace RCU 0.5.0 | |
| 506 | * Version 0.5.0 changes the API presented by memory model, | |
| 507 | architecture abstraction and data structure primitives in | |
| 508 | headers. The prefixes are, respectively: | |
| 509 | - cmm_ : Concurrent Memory Model | |
| 510 | - caa_ : Concurrent Architecture Abstraction | |
| 511 | - cds_ : Concurrent Data Structures | |
| 512 | ||
| 513 | 2010-03-04 Userspace RCU 0.4.2 | |
| 514 | * Add generic uatomic ops support. | |
| 515 | * Bugfix in urcu-bp. (rare garbage collection bug occurring in | |
| 516 | multithreaded environment). Only affects urcu-bp users (UST). | |
| 517 | ||
| 518 | 2010-02-12 Userspace RCU 0.4.1 | |
| 519 | * s390: compilation fix. | |
| 520 | ||
| 521 | 2010-01-30 Userspace RCU 0.4.0 | |
| 522 | * API change: SIGURCU -> SIGRCU | |
| 523 | * API changes: standardize on rcu_ prefix. | |
| 524 | * API change: urcu_init -> rcu_init. | |
| 525 | * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE, | |
| 526 | CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH. | |
| 527 | ((moving from URCU -> RCU). | |
| 528 | * library names changes: liburcu becomes the "default" version, using | |
| 529 | sys_membarrier() when available, and using liburcu-mb as a | |
| 530 | fallback. | |
| 531 | * The signal-based liburcu is renamed from liburcu to | |
| 532 | liburcu-signal. People previously using the signal-based | |
| 533 | "liburcu" will automatically be moved to the "default" liburcu | |
| 534 | version. | |
| 535 | ||
| 536 | 2009-11-16 Userspace RCU 0.3.1 | |
| 537 | * Add support for sparcv9 32-bit build. | |
| 538 | * Update build system to use --host instead of --target. | |
| 539 | ||
| 540 | 2009-11-03 Userspace RCU 0.3.0 | |
| 541 | * API change for the "deferred work" interface. | |

| 544 | * Move to autotools. | |
| 545 | * Automated architecture detection, with i386 fallback. | |
| 546 | * Detect if NR_futex is on the system, fallback on portable | |
| 547 | alternatives. | |
| 548 | * Add configure mode for UP-only systems. | |
| 549 | ||
| 550 | 2009-10-02 Userspace RCU 0.2.2 | |
| 551 | * Phases out rcu_publish_content() api. | |
| 552 | * Adds type checking to urcu-pointer.h pointer exchange primitives. | |
| 553 | ||
| 554 | 2009-10-02 Userspace RCU 0.2.1 | |
| 555 | * small header dependency fix for rculist.h. | |
| 556 | * new "liburcu-bp.so" : "Bulletproof RCU", made especially for | |
| 557 | the UST userspace tracer. It's a library that sacrifices a bit | |
| 558 | of read-side performance for automatically monitoring thread | |
| 559 | creation/removal. See README for details. | |
| 560 | ||
| 561 | 2009-10-01 Userspace RCU 0.2 | |
| 562 | * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer, | |
| 563 | rcu_set_pointer. | |
| 564 | ||
| 565 | 2009-09-29 Userspace RCU 0.1 | |
| 566 | * Initial release. |
