165 | 2011-06-27 Userspace RCU 0.6.3 |
166 | * uatomic: Fix i386 compatibility build errors in uatomic. | |
167 | ||
168 | 2011-06-13 Userspace RCU 0.6.2 | |
169 | * Fix build on powerpc. | |
170 | ||
171 | 2011-06-13 Userspace RCU 0.6.1 | |
172 | * Add missing headers into release tarball: | |
173 | urcu-call-rcu-impl.h and urcu-defer-impl.h | |
174 | ||
175 | 2011-06-10 Userspace RCU 0.6.0 | |
176 | * Added call_rcu() support, graciously contributed by Paul E. McKenney. | |
177 | * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS) | |
178 | into a single .so: liburcu-cds.so to have a single header/shared | |
179 | object holding all concurrency-aware data containers. It provides | |
180 | support for RCU lists, queues and stacks at the moment. | |
181 | * liburcu 0.6.0 now allows linking a single application with multiple | |
182 | flavors of RCU. This required a library API change which is | |
183 | incompatible with older 0.5.x liburcu. The .so version number | |
184 | is therefore bumped from 0 to 1 (e.g. liburcu.so.1). | |
185 | * Added "atfork" handling API, documented in README. Only useful for | |
186 | processes using fork() without following exec(). | |
187 | * Renaming the following files, keeping the old files (producing a | |
188 | compiler warning): | |
189 | urcu/uatomic_arch.h -> urcu/uatomic.h | |
190 | urcu/urcu-futex.h -> urcu/futex.h | |
191 | urcu/urcu_ref.h -> urcu/ref.h | |
192 | ||
193 | 2011-03-04 Userspace RCU 0.5.4 | |
194 | * urcu-bp: Update fork() handling | |
195 | ||
196 | Introduce | |
197 | ||
198 | extern void rcu_bp_before_fork(void); | |
199 | extern void rcu_bp_after_fork_parent(void); | |
200 | extern void rcu_bp_after_fork_child(void); | |
201 | ||
202 | to handle fork gracefully. These disable signals and hold | |
203 | the registry mutex across forks. (this flavor of the liburcu | |
204 | library ("bp" for "bulletproof") is mainly used by UST, the | |
205 | user-space tracer). | |
206 | ||
207 | 2011-03-03 Userspace RCU 0.5.3 | |
208 | * Add support for older ARM single-CPU architecturess (pre-ARMv7) | |
209 | (thanks to Jason Wessel from WindRiver). | |
210 | * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier). | |
211 | * Remove leftover list_t type from urcu/list.h (namespace cleanup). | |
212 | * urcu_defer: handle malloc error value. | |
213 | * Update README file to describe urcu interaction with fork() when not | |
214 | * followed | |
215 | by an exec() system call. | |
216 | ||
217 | 2010-11-18 Userspace RCU 0.5.2 | |
218 | * Fix renaming error introduced in 0.5.0. | |
219 | ||
220 | 2010-11-18 Userspace RCU 0.5.1 | |
221 | * Fix renaming error introduced in 0.5.0. (incomplete fix) | |
222 | ||
223 | 2010-11-18 Userspace RCU 0.5.0 | |
224 | * Version 0.5.0 changes the API presented by memory model, | |
225 | architecture abstraction and data structure primitives in | |
226 | headers. The prefixes are, respectively: | |
227 | - cmm_ : Concurrent Memory Model | |
228 | - caa_ : Concurrent Architecture Abstraction | |
229 | - cds_ : Concurrent Data Structures | |
230 | ||
231 | 2010-03-04 Userspace RCU 0.4.2 | |
232 | * Add generic uatomic ops support. | |
233 | * Bugfix in urcu-bp. (rare garbage collection bug occurring in | |
234 | multithreaded environment). Only affects urcu-bp users (UST). | |
235 | ||
236 | 2010-02-12 Userspace RCU 0.4.1 | |
237 | * s390: compilation fix. | |
238 | ||
239 | 2010-01-30 Userspace RCU 0.4.0 | |
240 | * API change: SIGURCU -> SIGRCU | |
241 | * API changes: standardize on rcu_ prefix. | |
242 | * API change: urcu_init -> rcu_init. | |
243 | * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE, | |
244 | CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH. | |
245 | ((moving from URCU -> RCU). | |
246 | * library names changes: liburcu becomes the "default" version, using | |
247 | sys_membarrier() when available, and using liburcu-mb as a | |
248 | fallback. | |
249 | * The signal-based liburcu is renamed from liburcu to | |
250 | liburcu-signal. People previously using the signal-based | |
251 | "liburcu" will automatically be moved to the "default" liburcu | |
252 | version. | |
253 | ||
254 | 2009-11-16 Userspace RCU 0.3.1 | |
255 | * Add support for sparcv9 32-bit build. | |
256 | * Update build system to use --host instead of --target. | |
257 | ||
258 | 2009-11-03 Userspace RCU 0.3.0 | |
259 | * API change for the "deferred work" interface. | |
260 | ||
261 | 2009-10-14 Userspace RCU 0.2.3 | |
262 | * Move to autotools. | |
263 | * Automated architecture detection, with i386 fallback. | |
264 | * Detect if NR_futex is on the system, fallback on portable | |
265 | alternatives. | |
266 | * Add configure mode for UP-only systems. | |
267 | ||
268 | 2009-10-02 Userspace RCU 0.2.2 | |
269 | * Phases out rcu_publish_content() api. | |
270 | * Adds type checking to urcu-pointer.h pointer exchange primitives. | |
271 | ||
272 | 2009-10-02 Userspace RCU 0.2.1 | |
273 | * small header dependency fix for rculist.h. | |
274 | * new "liburcu-bp.so" : "Bulletproof RCU", made especially for | |
275 | the UST userspace tracer. It's a library that sacrifices a bit | |
276 | of read-side performance for automatically monitoring thread | |
277 | creation/removal. See README for details. | |
278 | ||
279 | 2009-10-01 Userspace RCU 0.2 | |
280 | * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer, | |
281 | rcu_set_pointer. | |
282 | ||
283 | 2009-09-29 Userspace RCU 0.1 | |
284 | * Initial release. |
