* io-threads: Fix missed notification in sem_timedwaitShehjar Tikoo2009-06-112-5/+4
| | | | | | | | | | | | | | | We're performing a calculation for skewing idle time that resulted in a timespec.tv_nsec value becoming larger than 1000 million or less than 0, forcing sem_timedwait to return with an EINVAL instead of waiting for a request notification from sem_post in iot_notify_worker(). This resulted in a missed notification that resulted in a hang followed by a timeout on the protocol/client side. This commit avoids the over- and under-flow in tv_nsec by skewing the tv_sec value instead. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>

* io-threads: Change mutexes/condvars to spinlocks/semaphoresShehjar Tikoo2009-05-202-36/+80
| | | | | | | | | | | | | | | | | It seems that use of mutexes is resulting in pretty high thread sleep and wake-up cost. What is worse, if a worker thread has acquired a lock, there is a possibility of the main glusterfs thread being put to sleep. We change the use of mutexes into spinlock. At the same time, we cannot anymore use condvars for notification since the condvar interface depends on mutexes itself. Semaphores come to out rescue. Luckily, even the pthread semaphores have a timedwait interface to allow our idle worker threads to make an exit decision. Further, it is possible that spinlocks are not available on all systems so all this is curtained behind #defines so we can fall back to mutexes and condvars implementation. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* io-threads: Reduce default max for threads to 64Shehjar Tikoo2009-05-201-1/+1
| | | | | | | | | We've had complaints from users who've used autoscaling option with default settings for min and max threads, about high memory consumption because of the large default value for max-threads. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* io-threads: Support mem-pool allocator for iot_request_tShehjar Tikoo2009-05-202-23/+44
| | | | | | | | | | | | | | | | This commit brings in support for allocation of iot_request_t's in io-threads through the use of the mem-pool. We're hoping that the overheads of hundreds and thousands of small allocations can be avoided through this. The important point to note is that the memory pool is not for the translator as a whole but there is one small memory pool for each worker thread. Not only does that help us avoid malloc overheads for small allocations like iot_request_t but also avoid contention on the heap data structures when multiple threads want an iot_request_t from the pool.

* io-threads: Clarify thread count rangeShehjar Tikoo2009-05-052-16/+23
| | | | | | | | | | | | | | | This patch cleans up io-threads behaviour regarding the range values that can be specified for min-threads and max-threads. THe major change is that the min threads have been reduced to 2 to signify that io-threads needs minimum two threads for its operation, while keeping the default number of threads at 16. The idea is to decouple the default thread count from the minimum thread count. Note to Avati: This applies over Raghu's indentation and logging take-3 patch. Signed-off-by: Anand V.
