aa120cd0 MD |
95 | 2011-06-27 Userspace RCU 0.6.3 |
96 | * uatomic: Fix i386 compatibility build errors in uatomic. | |
97 | ||
98 | 2011-06-13 Userspace RCU 0.6.2 | |
99 | * Fix build on powerpc. | |
100 | ||
101 | 2011-06-13 Userspace RCU 0.6.1 | |
102 | * Add missing headers into release tarball: | |
103 | urcu-call-rcu-impl.h and urcu-defer-impl.h | |
104 | ||
105 | 2011-06-10 Userspace RCU 0.6.0 | |
106 | * Added call_rcu() support, graciously contributed by Paul E. McKenney. | |
107 | * Added urcu/cds.h and merged all "Concurrent Data Containers" (CDS) | |
108 | into a single .so: liburcu-cds.so to have a single header/shared | |
109 | object holding all concurrency-aware data containers. It provides | |
110 | support for RCU lists, queues and stacks at the moment. | |
111 | * liburcu 0.6.0 now allows linking a single application with multiple | |
112 | flavors of RCU. This required a library API change which is | |
113 | incompatible with older 0.5.x liburcu. The .so version number | |
114 | is therefore bumped from 0 to 1 (e.g. liburcu.so.1). | |
115 | * Added "atfork" handling API, documented in README. Only useful for | |
116 | processes using fork() without following exec(). | |
117 | * Renaming the following files, keeping the old files (producing a | |
118 | compiler warning): | |
119 | urcu/uatomic_arch.h -> urcu/uatomic.h | |
120 | urcu/urcu-futex.h -> urcu/futex.h | |
121 | urcu/urcu_ref.h -> urcu/ref.h | |
122 | ||
123 | 2011-03-04 Userspace RCU 0.5.4 | |
124 | * urcu-bp: Update fork() handling | |
125 | ||
126 | Introduce | |
127 | ||
128 | extern void rcu_bp_before_fork(void); | |
129 | extern void rcu_bp_after_fork_parent(void); | |
130 | extern void rcu_bp_after_fork_child(void); | |
131 | ||
132 | to handle fork gracefully. These disable signals and hold | |
133 | the registry mutex across forks. (this flavor of the liburcu | |
134 | library ("bp" for "bulletproof") is mainly used by UST, the | |
135 | user-space tracer). | |
136 | ||
137 | 2011-03-03 Userspace RCU 0.5.3 | |
138 | * Add support for older ARM single-CPU architecturess (pre-ARMv7) | |
139 | (thanks to Jason Wessel from WindRiver). | |
140 | * Fix ARMv7 cmm_rmb/cmm_wmb primitives (use a dmb barrier). | |
141 | * Remove leftover list_t type from urcu/list.h (namespace cleanup). | |
142 | * urcu_defer: handle malloc error value. | |
143 | * Update README file to describe urcu interaction with fork() when not | |
144 | * followed | |
145 | by an exec() system call. | |
146 | ||
147 | 2010-11-18 Userspace RCU 0.5.2 | |
148 | * Fix renaming error introduced in 0.5.0. | |
149 | ||
150 | 2010-11-18 Userspace RCU 0.5.1 | |
151 | * Fix renaming error introduced in 0.5.0. (incomplete fix) | |
152 | ||
153 | 2010-11-18 Userspace RCU 0.5.0 | |
154 | * Version 0.5.0 changes the API presented by memory model, | |
155 | architecture abstraction and data structure primitives in | |
156 | headers. The prefixes are, respectively: | |
157 | - cmm_ : Concurrent Memory Model | |
158 | - caa_ : Concurrent Architecture Abstraction | |
159 | - cds_ : Concurrent Data Structures | |
160 | ||
161 | 2010-03-04 Userspace RCU 0.4.2 | |
162 | * Add generic uatomic ops support. | |
163 | * Bugfix in urcu-bp. (rare garbage collection bug occurring in | |
164 | multithreaded environment). Only affects urcu-bp users (UST). | |
165 | ||
166 | 2010-02-12 Userspace RCU 0.4.1 | |
167 | * s390: compilation fix. | |
168 | ||
169 | 2010-01-30 Userspace RCU 0.4.0 | |
170 | * API change: SIGURCU -> SIGRCU | |
171 | * API changes: standardize on rcu_ prefix. | |
172 | * API change: urcu_init -> rcu_init. | |
173 | * urcu/config.h options renamed to CONFIG_RCU_HAVE_FENCE, | |
174 | CONFIG_RCU_HAVE_FUTEX, CONFIG_RCU_SMP, CONFIG_RCU_COMPAT_ARCH. | |
175 | ((moving from URCU -> RCU). | |
176 | * library names changes: liburcu becomes the "default" version, using | |
177 | sys_membarrier() when available, and using liburcu-mb as a | |
178 | fallback. | |
179 | * The signal-based liburcu is renamed from liburcu to | |
180 | liburcu-signal. People previously using the signal-based | |
181 | "liburcu" will automatically be moved to the "default" liburcu | |
182 | version. | |
183 | ||
184 | 2009-11-16 Userspace RCU 0.3.1 | |
185 | * Add support for sparcv9 32-bit build. | |
186 | * Update build system to use --host instead of --target. | |
187 | ||
188 | 2009-11-03 Userspace RCU 0.3.0 | |
189 | * API change for the "deferred work" interface. | |
190 | ||
191 | 2009-10-14 Userspace RCU 0.2.3 | |
192 | * Move to autotools. | |
193 | * Automated architecture detection, with i386 fallback. | |
194 | * Detect if NR_futex is on the system, fallback on portable | |
195 | alternatives. | |
196 | * Add configure mode for UP-only systems. | |
197 | ||
198 | 2009-10-02 Userspace RCU 0.2.2 | |
199 | * Phases out rcu_publish_content() api. | |
200 | * Adds type checking to urcu-pointer.h pointer exchange primitives. | |
201 | ||
202 | 2009-10-02 Userspace RCU 0.2.1 | |
203 | * small header dependency fix for rculist.h. | |
204 | * new "liburcu-bp.so" : "Bulletproof RCU", made especially for | |
205 | the UST userspace tracer. It's a library that sacrifices a bit | |
206 | of read-side performance for automatically monitoring thread | |
207 | creation/removal. See README for details. | |
208 | ||
209 | 2009-10-01 Userspace RCU 0.2 | |
210 | * Clarify usage of rcu_cmpxchg_pointer, rcu_xchg_pointer, | |
211 | rcu_set_pointer. | |
212 | ||
213 | 2009-09-29 Userspace RCU 0.1 | |
214 | * Initial release. |
