this fixes a major gap in the intended functionality of pthread_setattr_default_np. if application/library code creating a thread does not pass a null attribute pointer to pthread_create, but sets up an attribute object to change other properties while leaving the stack alone, the created thread will get a stack with size DEFAULT_STACK_SIZE. this makes pthread_setattr_default_np useless for working around stack overflow issues in such applications, and leaves a major risk of regression if previously-working code switches from using a null attribute pointer to an attribute object. this change aligns the behavior more closely with the glibc pthread_setattr_default_np functionality too, albeit via a different mechanism. glibc encodes "default" specially in the attribute object and reads the actual default at thread creation time. with this commit, we now copy the current default into the attribute object at pthread_attr_init time, so that applications that query the properties of the attribute object will see the right values. |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
