Re: [E-devel] Evas & deadlock
On Fri, 2 Oct 2009 05:43:30 -0400 Atton Jonathan said: only way this can deadlock is if... 1. realloc() failed on the queue - this means u must be out of memory or memory space. u're in deep trouble if you get here. i've fixed this. it now unloack on abort if realloc fails, but i dont think this is the problem or 2. evas_async_events_put() is somehow called from evas_async_events_process() which that helgrind doesn seem to show. it hints that 2 fdifferent mutexes are in fact the same one! the mutex being locked from _evas_cache_image_make_activ () is not the same one being locked in evas_async_events_put() and evas_async_events_process(). both are: static pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; and static pthread_mutex_t _mutex = PTHREAD_MUTEX_INITIALIZER; but then there must be something deadlocking somehwere.. but i cant see just where. what i'll do is restructure a bit to remove the locks around the callback calling. that may help. > hello, > > I use ptotocam in my application and sometimes I have a deadlock in evas. > Maybe the problem is not directly photocam. > > Here the lock where the application freeze : > http://debian.pastebin.com/m66475a30 > > Helgrind show me a lock order violation : > http://debian.pastebin.com/m1b6e6fa7 > > -- > Regards. > -- > Come build with us!
