* Handles spurious wake-ups in pthread_join()msg5552013-06-121-6/+3
| | | | | | | | | | | | | | | | | | | Removed 'join_count' from pthread_internal_t and switched to using the flag PTHREAD_ATTR_FLAG_JOINED to indicate if a thread is being joined. Combined with a switch to a while loop in pthread_join, this fixes spurious wake-ups but prevents a thread from being joined multiple times. This is fine for two reasons: 1) The pthread_join specification allows for undefined behavior when multiple threads try to join a single thread. 2) There is no thread safe way to allow multiple threads to join a single thread with the pthread interface. The second thread calling pthread_join could be pre-empted until the thread is destroyed and its handle reused for a different thread. Therefore multi-join is always an error.

| | | | | | | | | | | | | | | | | | | | POSIX says pthread_create returns EAGAIN, not ENOMEM. Also pull pthread_attr_t functions into their own file. Also pull pthread_setname_np into its own file. Also remove unnecessary #includes from pthread_key.cpp. Also account for those pthread keys used internally by bionic, so they don't count against the number of keys available to user code. (They do with glibc, but glibc's limit is the much more generous 1024.) Also factor out the common errno-restoring idiom to reduce gotos.

This was originally motivated by noticing that we were setting the wrong bits for the well-known tls entries. That was a harmless bug because none of the well-known tls entries has a destructor, but it's best not to leave land mines lying around. Also add some missing POSIX constants, a new test, and fix pthread_key_create's return value when we hit the limit. Change-Id: Ife26ea2f4b40865308e8410ec803b20bcc3e0ed1
