This is due to + limitations in the Hurd TSD implementation + (c.f. ). + +** Cancelation +*** Cancelation points + The only cancelation points are pthread_join, pthread_cond_wait, + pthead_cond_timedwait and pthread_testcancel. Need to explore if + the hurd_sigstate->cancel_hook (c.f. ) provides the + desired semantics. If not, must either wrap the some functions + using dlsym or wait until integration with glibc. +*** Async cancelation + We inject a new IP into the cancelled (running) thread and then + run the cancelation handlers + (c.f. sysdeps/mach/hurd/pt-docancel.c). The handlers need to have + access to the stack as they may use local variables. I think that + this method may leave the frame pointer in a corrupted state if + the thread was in, for instance, the middle of a function call. + The robustness needs to be confirmed. + +** Process Shared Attribute + + Currently, there is no real support for the process shared + attribute. spinlocks work because we just use a test and set loop, + however, barriers, conditions mutexes and rwlocks, however, signal + wakeups via ports of which the names are process local. + + We could have some process local data that is hashed to via the + address of the data structure. Then the first thread that blocks + per process would spin on the shared memory area and all others + would then block as normal. When the resource became available, + the first thread would signal the other local threads as necessary. + Alternatively, there could be some server, however, this opens a + new question: what can we use as an authentication agent. + +** Locking algorithm + + When a thread blocks, it puts itself on a queue and then waits for + a message on a thread local port. The thread which eventually does + the wakeup sends a message to the waiter thereby waking it up. If + the wakeup is a broadcast wakeup (e.g. pthread_cond_broadcast, + pthread_barrier_wait and pthread_rdlock_unlock), the thread must + send O(N) messages where N is the number of waiting threads. If + all the threads instead received on a lock local (rather than + thread local) port then the thread which eventually does the wake + need just do one operation, mach_port_destroy and all of the + waiting threads would wakeup and get MACH_RCV_PORT_DIED back from + mach_msg. Note that the trade off is that the port must be + recreated. This needs to be benchmarked. + + A possible problem with this is scheduling priorities. There may + be a preference for certain threads to wakeup before others + (especially if we are not doing a broadcast, for instance, + pthread_mutex_unlock and pthread_cond_signal). If we take this + approach, the kernel chooses which threads are awakened. If we + find that the kernel makes the wrong choices, we can still overcome + this by merging the two algorithms: have a list of ports sorted in + priority order and the waker does a mach_port_destroy on each as + appropriate. + +** Barriers + + Barriers can be very slow and the contention can be very high. The + above algorithm is very appealing, however, this may be augmented + with an initial number of spins and yields. It is expected that + all of the threads reach the barrier within close succession, thus + queuing a message may be more expensive. This needs to be + benchmarked. + +** Clocks +*** pthread_condattr_setclock allows a process to specify a clock for + use with pthread_cond_timedwaits. What is the correct default for + this, right now, we use CLOCK_REALTIME, however, we are really + using the system clock which, if I understand correctly, is + completely different. +*** Could we even use other clocks? mach_msg uses a relative time against + the system clock. +*** pthread_getcpuclockid just returns CLOCK_THREAD_CPUTIME_ID if defined. + Is this the correct behavior? + +** Timed Blocking +*** pthread_cond_timedwait, pthead_mutex_timedlock, pthread_rwlock_timedrdlock + and pthread_rwlock_timedwrlock all take absolute times.
