2011-03-17implement robust mutexesRich Felker-2/+11
some of this code should be cleaned up, e.g. using macros for some of the bit flags, masks, etc. nonetheless, the code is believed to be working and correct at this point.
2011-03-17avoid function call to pthread_self in mutex unlockRich Felker-1/+1
if the mutex was previously locked, we can assume pthread_self was already called at the time of locking, and thus that the thread pointer is initialized.
2011-03-17unify lock and owner fields of mutex structureRich Felker-2/+1
this change is necessary to free up one slot in the mutex structure so that we can use doubly-linked lists in the implementation of robust mutexes.
2011-03-08fix and optimize non-default-type mutex behaviorRich Felker-8/+5
problem 1: mutex type from the attribute was being ignored by pthread_mutex_init, so recursive/errorchecking mutexes were never being used at all. problem 2: ownership of recursive mutexes was not being enforced at unlock time.
2011-02-17reorganize pthread data structures and move the definitions to alltypes.hRich Felker-8/+8
this allows sys/types.h to provide the pthread types, as required by POSIX. this design also facilitates forcing ABI-compatible sizes in the arch-specific alltypes.h, while eliminating the need for developers changing the internals of the pthread types to poke around with arch-specific headers they may not be able to test.
