291 under [HAVE_TLS_SUPPORT] so we can rely on the initialization done
292 by the first thread's early TLS setup.
294 2002-08-15 Roland McGrath <roland@redhat.com>
296 * sysdeps/i386/tls.h (TLS_INIT_TP): Use statement expression and

1554 same: pthread_mutexattr_settype() and pthread_mutexattr_gettype().
1555 Changes references to PTHREAD_MUTEXATTR_FAST_NP to
1556 PTHREAD_MUTEXATTR_ADAPTIVE_NP.
1557 Begins to introduce discussion of the ``timed'' mutex type. This
1558 discussion is currently incomplete.

2136 2000-06-19 H.J. Lu <hjl@gnu.org>
2138 * spinlock.h (HAS_COMPARE_AND_SWAP): Defined if
2139 HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS is defined.
2140 (compare_and_swap_with_release_semantics): New. Default to
2141 compare_and_swap if HAS_COMPARE_AND_SWAP_WITH_RELEASE_SEMANTICS
2142 is not defined.
2144 * spinlock.c (__pthread_unlock): Call
2145 compare_and_swap_with_release_semantics () instead of
2146 compare_and_swap ().
2148 2000-06-19 Ulrich Drepper <drepper@redhat.com>
2150 * sysdeps/pthread/timer_create.c: Use _set_errno instead of assigning

2157 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
2159 Timer nodes are now reference counted, and can be marked
2160 as deleted. This allows for the safe release of the global mutex
2161 in the middle without losing the timer being operated on.
2163 * sysdeps/pthread/posix-timer.h (struct timer_node): The inuse
2164 member is now an enum with three values, so that an intermediate
2165 state can be represented (deleted but not free for reuse yet).
2166 New refcount member added.
2167 * sysdeps/pthread/timer_routines.c: Likewise.
2169 * sysdeps/pthread/posix-timer.h (timer_addref, timer_delref,

2173 restructured, recursive deadlock bug fixed.
2175 * sysdeps/pthread/timer_gettime.c (timer_gettime): Uses new
2176 timer_addref to ensure that timer won't be deleted while mutex is not
2177 held. Also uses timer_invalid to perform validation of timer handle.
2178 * sysdeps/pthread/timer_settime.c (timer_settime): Likewise.
2179 * sysdeps/pthread/timer_getoverr.c (timer_getoverrun): Likewise.
2181 2000-06-14 Ulrich Drepper <drepper@redhat.com>
2183 * shlib-versions: Add entry for SH.
2184 Patch by Kaz Kojima <kkojima@rr.iij4u.or.jp>.
2186 2000-06-13 Kaz Kylheku <kaz@ashi.footprints.net>
2188 A few optimizations. Got rid of unnecessary wakeups of timer threads,
2189 tightened up some critical regions and micro-optimized some list
2190 manipulation code.
2192 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2193 Returns int value now to indicate whether timer was queued at head.
2194 * sysdeps/pthread/posix-timer.h: Likewise.
2195 * sysdeps/pthread/timer_settime.c (timer_settime): Takes advantage of
2196 new return value from __timer_thread_queue_timer to avoid waking
2197 up timer thread unnecessarily.
2199 * sysdeps/pthread/posix-timer.h (timer_id2ptr): No longer checks
2200 inuse flag, because this requires mutex to be held. Callers updated
2201 to do the check when they have the mutex.
2202 * sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
2204 * sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
2205 regions: avoids making system calls while holding timer mutex, and
2206 a few computations were moved outside of the mutex as well.
2207 * sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
2209 * sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
2210 to list_unlink_ip, meaning idempotent. Pointer manipulation
2211 changed to get better better code out of gcc.
2212 * sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
2213 version of list_unlink added here.
2214 * sysdeps/pthread/timer_delete.c: Use appropriate list unlink
2215 function in all places: idempotent one for timers, non-idempotent
2216 one for thread nodes.
2217 * sysdeps/pthread/timer_settime: Likewise.
2218 * sysdeps/pthread/timer_routines.c: Likewise.
2220 2000-06-13 Ulrich Drepper <drepper@redhat.com>
2222 * sysdeps/unix/sysv/linux/bits/posix_opt.h (_POSIX_TIMERS): Define.
2223 * sysdeps/unix/sysv/linux/i386/bits/posix_opt.h: Likewise.

2242 (__pthread_spin_trylock): Implement.
2243 (__pthread_spin_unlock): Implement.
2244 (__pthread_spin_init): Implement.
2245 (__pthread_spin_destroy): Implement.
2247 2000-06-10 Ulrich Drepper <drepper@redhat.com>
2249 * sysdeps/pthread/timer_routines.c (list_append): Little fix to
2250 really append the entry.
2252 2000-06-10 Andreas Jaeger <aj@suse.de>
2254 * lockfile.c (__fresetlockfiles): Remove unused variable fp.
2256 2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net>
2258 * sysdeps/pthread/timer_create.c: Thread matching now done on
2259 clock type as well as thread attributes.
2260 There are individual global signal-delivering threads for
2261 different clock types.
2262 * sysdeps/pthread/posix-timer.h: Likewise.
2263 * sysdeps/pthread/timer_routines.c: Likewise.
2265 * sysdeps/pthread/timer_routines.c: Thread allocation and
2266 deallocation function now remembers to put thread on active
2267 list and remove from active list.
2268 Thus now the feature of binding multiple timers
2269 to a single thread actually works.
2271 2000-06-10 Ulrich Drepper <drepper@redhat.com>
2273 * pthread.c (__pthread_create_2_1): Optimize a bit.
2275 * internals.h (invalid_handle): Also test for p_terminated != 0.
2276 (nonexisting_handle): New function. Same as old invalid_handle.
2277 * join.c (pthread_join): Use nonexisting_handle instead of
2278 invalid_handle to test for acceptable thread handle.
2279 * manager.c (pthread_handle_free): Likewise.
2280 * joinrace.c: New file.
2281 Reported by Permaine Cheung <pcheung@cygnus.com>.
2283 2000-06-08 Ulrich Drepper <drepper@redhat.com>
2285 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2286 Correct handling of matching variable.
2288 * sysdeps/pthread/tst-timer.c (main): Rewrite initializers to
2289 avoid warnings.
2291 * sysdeps/pthread/timer_routines.c (__timer_thread_queue_timer):
2292 Be prepared for empty timer list.
2294 * sysdeps/pthread/timer_create.c (timer_create): Correct names of
2295 CPUTIME clock ID. Add support for thread clocks.
2297 * sysdeps/pthread/posix-timer.h (timer_ptr2id): Operands in
2298 subtraction were switched.
2300 * sysdeps/pthread/timer_routines.c (init_module): Use
2301 THREAD_MAXNODES threads.
2303 * sysdeps/pthread/posix-timer.h (struct timer_node): Add creator_pid.
2304 * sysdeps/pthread/timer_create.c: Fill in creator_pid.
2305 * sysdeps/pthread/timer_routines.c (thread_expire_timer): Send signal
2306 with sigqueueinfo is this system call is available.
2308 * sysdeps/pthread/timer_create.c (timer_create): Allow
2309 CLOCK_CPUTIME if _POSIX_CPUTIME is defined.
2311 * sysdeps/pthread/Makefile: New file. Add rules to build timer
2312 functionality.
2313 * sysdeps/unix/sysv/linux/bits/local_lim.h: Add TIMER_MAX.
2315 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>

2326 2000-06-08 Ulrich Drepper <drepper@redhat.com>
2328 * sysdeps/unix/sysv/linux/bits/local_lim.h: Remove OPEN_MAX and
2329 LINK_MAX definitions if necessary.
2331 2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
2333 Added missing fork time handling of global libio lock.
2335 * lockfile.c (__fresetlockfiles): Now also resets the list lock,
2336 not just the individual stream locks. Rewritten to use new
2337 iterator interface provided by libio rather than accessing
2338 global variable.
2340 * lockfile.c (__flockfilelist, _funlockfilelist): New functions
2341 which lock and unlock the stream list using the new interface
2342 provied by libio.
2343 * internals.h: Likewise.
2345 * ptfork.c (__fork): Now calls __flockfilelist before fork,
2346 and __funlockfilelist in the parent after the fork.
2347 Child still calls __fresetlockfiles as before.
2349 * linuxthreads.texi: Now explains what happens to streams at
2350 fork time. Also whole new section on forking and thread added.
2351 Definition of pthread_atfork moved out of Miscellaneous Functions
2352 to this new section.
2354 2000-06-04 Jakub Jelinek <jakub@redhat.com>
2356 * sysdeps/sparc/sparc32/sparcv9/pspinlock.c (__pthread_spin_lock):

2375 * Examples/ex8.c: New file.
2377 2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
2379 Bugfix: The pthread_atfork mechanism now takes care of its
2380 own internal mutex at fork time.
2382 * ptfork.c (__fork): Revised so that the mutex is held across
2383 the fork operation and while the handlers are called, and so that
2384 the child resets the mutex.
2386 * linuxthreads.texi: Updated pthread_atfork documentation to make
2387 it clear that fork and pthread_atfork can't be reentered from
2388 atfork handlers, that pthread_atfork and fork are mutually atomic,
2389 and that the handlers are inherited by the child process.
2391 2000-05-24 Ulrich Drepper <drepper@redhat.com>
2393 * Makefile (libpthread-routines): Add pspinlock.
2394 * cancel.c: Rename __pthread_spin_unlock back to __pthread_unlock.
2395 Use struct _pthread_fastlock instead of pthread_spinlock_t.
2396 * condvar.c: Likewise.

2415 * sysdeps/pthread/bits/pthreadtypes.h: Remove pthread_spinlock_t
2416 back to _pthread_fastlock. Define new pthread_spinlock_t.
2418 2000-05-24 Andreas Jaeger <aj@suse.de>

2428 * internals.h (__RES_PTHREAD_INTERNAL): Define.
2430 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2432 * mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
2433 object state is represented with additional bits which distinguish
2434 whether that state was set up in the current process, or
2435 in an ancestor process. If that state was set in an ancestor,
2436 it means that a fork happened while thread was executing the init
2437 function. In that case, the state is reset to NEVER.
2438 * mutex.c (__pthread_once_fork_prepare): New function.
2439 (__pthread_once_fork_child): Likewise
2440 (__pthread_once_fork_parent): Likewise
2441 (__pthread_reset_pthread_once): Removed.
2442 * ptfork.c (__fork): Call new handlers in mutex.c.
2443 * internals.h: Declarations of new mutex.c functions added.
2444 Declaration of removed function deleted.
2445 * linuxthreads.texi: Updated documentation about pthread_once
2446 to clarify what happens under cancellation and forking.
2448 2000-05-06 Kaz Kylheku <kaz@ashi.footprints.net>
2450 * internals.h: New thread manager request type, REQ_KICK.
2451 * join.c (pthread_exit): main thread now calls exit() instead
2452 of _exit() in order to proper process cleanup.
2453 * manager.c (__pthread_manager): Do not terminate manager
2454 after unblocking main thread; wait for main thread's
2455 REQ_PROCESS_EXIT request instead.
2456 Also, added REQ_KICK case to handle new request; this just does
2457 nothing.
2458 * manager.c (pthread_exited): Do not terminate manager after
2459 unblocking main thread.
2460 * manager.c (__pthread_manager_sighandler): If the main thread
2461 is waiting for all other threads to die, send a REQ_KICK into
2462 the thread manager request pipe to get it to clean out the threads
2463 and unblock the main thread as soon as possible. This fixes
2464 the 2000 millisecond hang on shutdown bug.
2465 * Examples/ex7.c: New file, tests shutdown behavior when all threads
2466 including the main one call pthread_exit(), or implicitly do so.
2467 * Makefile (tests): Add ex7.
2469 2000-05-05 Andreas Jaeger <aj@suse.de>

2484 2000-04-29 Bruno Haible <haible@clisp.cons.org>
2486 * join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
2487 for eventmask larger than 1 word.
2489 2000-04-27 Ulrich Drepper <drepper@redhat.com>

2492 * pthread.c (__pthread_initialize_minimal): New function. Perform
2493 minimal initialization.
2494 (pthread_initialize): Remove this code here.
2495 * sysdeps/i386/i686/pt-machine.h: Include "../useldt.h" again. We
2496 are working around the problem in glibc.
2498 2000-04-25 Ulrich Drepper <drepper@redhat.com>
2500 * sysdeps/i386/i686/pt-machine.h: Do not use "../useldt.h" for
2501 now. First gcc must be fixed (more concrete: libgcc).
2503 2000-04-24 Ulrich Drepper <drepper@redhat.com>
2505 * pthread.c: Remove special treatement for interrupt handlers on x86.
2506 * manager.c (pthread_free): Use FREE_THREAD not FREE_THREAD_SELF.
2507 * sysdeps/i386/useldt.h: Use "q" constraint instead of "r" where
2508 necessary.

2511 2000-04-24 Mark Kettenis <kettenis@gnu.org>
2513 * join.c (pthread_exit): Set p_terminated after reporting the
2514 termination event instead of before.
2516 2000-04-20 Jakub Jelinek <jakub@redhat.com>
2518 * sysdeps/pthread/bits/libc-lock.h: Only declare __pthread_rwlock_*
2519 if __USE_UNIX98.

2841 Patch by khendricks@ivey.uwo.ca (PR libc/1561).

2883 2000-01-03 Kaz Kylheku <kaz@ashi.footprints.net>
2885 Redesigned how cancellation unblocks a thread from internal
2886 cancellation points (sem_wait, pthread_join,
2887 pthread_cond_{wait,timedwait}).
2888 Cancellation won't eat a signal in any of these functions
2889 (*required* by POSIX and Single Unix Spec!).
2890 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
2891 simultaneous condition variable signal (not required by POSIX
2892 or Single Unix Spec, but nice).
2893 * spinlock.c: __pthread_lock queues back any received restarts
2894 that don't belong to it instead of assuming ownership of lock
2895 upon any restart; fastlock can no longer be acquired by two threads
2896 simultaneously.
2897 * restart.h: Restarts queue even on kernels that don't have
2898 queued real time signals (2.0, early 2.1), thanks to atomic counter,
2899 avoiding a rare race condition in pthread_cond_timedwait.
2901 1999-12-31 Andreas Jaeger <aj@suse.de>

2941 pwrite64, lseek64, open64, and __open64.
2943 * manager.c (pthread_allocate_stack): Correct computation of
2944 new_thread_bottom. Correct handling of stack size and when the
2945 rlimit method to guard for stack growth is used.
2946 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
2947 minus one pagesize (not two).
2949 1999-12-03 Andreas Jaeger <aj@suse.de>
2951 * Versions: Add __res_state with version GLIBC_2.2.
2953 * errno.c (__res_state): New function to return thread specific
2954 resolver state.
2956 * pthread.c (pthread_initialize): Initialize p_resp.
2957 (__pthread_reset_main_thread): Also set p_resp.
2959 * manager.c (pthread_handle_create): Initialize p_resp.
2961 * internals.h: Add thread specific resolver state.

4159 Since sigset_t no longer fits in a register, we can't pass in the
4160 thread's initial mask so easily. Take this opportunity to simplify
4161 the clone implementation by only accepting a single void* argument.

4164 struct instead of as arguments through clone.
4165 (pthread_start_thread): Look for them there.
4166 * internals.h (struct _pthread): Add p_initial_fn,
4167 p_initial_fn_arg, p_initial_mask. Fix __pthread_manager proto.
4168 * pthread.c (pthread_initialize_manager): Revise clone invocation.
