2011-07-21 Userspace RCU 0.6.4
* uatomic: Fix ARM build errors in uatomic.
* urcu tests: hold mutex across use of custom allocator.
* Portability fixes to support FreeBSD 8.2.
2011-06-27 Userspace RCU 0.6.3
* uatomic: Fix i386 compatibility build errors in uatomic.
2011-06-13 Userspace RCU 0.6.2
* Fix build on powerpc.
2011-06-13 Userspace RCU 0.6.1
* Add missing headers into release tarball:
urcu-call-rcu-impl.h and urcu-defer-impl.h
2011-06-10 Userspace RCU 0.6.0
* Added call_rcu() support, graciously contributed by Paul E. McKenney.
* Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS)
into a single .so: liburcu-cds.so to have a single header/shared
object holding all concurrency-aware data containers. It provides
support for RCU lists, queues and stacks at the moment.
* liburcu 0.6.0 now allows linking a single application with multiple
flavors of RCU. This required a library API change which is
incompatible with older 0.5.x liburcu. The .so version number
is therefore bumped from 0 to 1 (e.g. liburcu.so.1).
* Added "atfork" handling API, documented in README. Only useful for
processes using fork() without following exec().
* Renaming the following files, keeping the old files (producing a
compiler warning):
urcu/uatomic_arch.h -> urcu/uatomic.h
urcu/urcu-futex.h -> urcu/futex.h
urcu/urcu_ref.h -> urcu/ref.h
2011-03-04 Userspace RCU 0.5.4
* urcu-bp: Update fork() handling
Introduce
extern void rcu_bp_before_fork(void);
extern void rcu_bp_after_fork_parent(void);
extern void rcu_bp_after_fork_child(void);
to handle fork gracefully. These disable signals and hold
the registry mutex across forks. (this flavor of the liburcu
library ("bp" for "bulletproof") is mainly used by UST, the
user-space tracer).
2011-03-03 Userspace RCU 0.5.3
* Add support for older ARM single-CPU architecturess (pre-ARMv7)
(thanks to Jason Wessel from WindRiver).
* Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier).
* Remove leftover list_t type from urcu/list.h (namespace cleanup).
* urcu_defer: handle malloc error value.
* Update README file to describe urcu interaction with fork() when not
* followed
by an exec() system call.
2010-11-18 Userspace RCU 0.5.2
* Fix renaming error introduced in 0.5.0.
2010-11-18 Userspace RCU 0.5.1
* Fix renaming error introduced in 0.5.0. (incomplete fix)
2010-11-18 Userspace RCU 0.5.0
* Version 0.5.0 changes the API presented by memory model,
architecture abstraction and data structure primitives in
headers. The prefixes are, respectively:
- cmm_ : Concurrent Memory Model
- caa_ : Concurrent Architecture Abstraction
- cds_ : Concurrent Data Structures
2010-03-04 Userspace RCU 0.4.2
* Add generic uatomic ops support.
* Bugfix in urcu-bp. (rare garbage collection bug occurring in
multithreaded environment). Only affects urcu-bp users (UST).
2010-02-12 Userspace RCU 0.4.1
* s390: compilation fix.
2010-01-30 Userspace RCU 0.4.0
* API change: SIGURCU -> SIGRCU
* API changes: standardize on rcu_ prefix.
* API change: urcu_init -> rcu_init.
* urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE,
CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH.
((moving from URCU -> RCU).
* library names changes: liburcu becomes the "default" version, using
sys_membarrier() when available, and using liburcu-mb as a
fallback.
* The signal-based liburcu is renamed from liburcu to
liburcu-signal. People previously using the signal-based
"liburcu" will automatically be moved to the "default" liburcu
version.
2009-11-16 Userspace RCU 0.3.1

* Adds type checking to urcu-pointer.h pointer exchange primitives.
2009-10-02 Userspace RCU 0.2.1
* small header dependency fix for rculist.h.
* new "liburcu-bp.so" : "Bulletproof RCU", made especially for
the UST userspace tracer. It's a library that sacrifices a bit
of read-side performance for automatically monitoring thread
creation/removal. See README for details.
2009-10-01 Userspace RCU 0.2
* Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer,
rcu_set_pointer.
2009-09-29 Userspace RCU 0.1
