*NSYNC

*NSYNC is a library providing scalable synchronization primitives. The following packages are provided:

  • THIRD_PARTY_NSYNC has nsync_mu which doesn't depend on malloc().
  • THIRD_PARTY_NSYNC_MEM has the rest of *NSYNC, e.g. nsync_cv.

The origin of this code is here:

NSYNC uses the Apache 2.0 license. We made the following local changes:

  • Write custom nsync_malloc_() so malloc() can use *NSYNC.

  • Rewrite futex() wrapper to support old Linux kernels and OpenBSD.

  • Normalize sources to Cosmopolitan style conventions; *NSYNC upstream supports dozens of compilers and operating systems, at compile-time. Since Cosmo solves portability at runtime instead, most of the build config toil has been removed, in order to help the NSYNC source code be more readable and hackable.
