2020-10-28runtime: set up TLS without cgo on darwin/arm64Cherry Zhang
Currently, on darwin/arm64 we set up TLS using cgo. TLS is not set for pure Go programs. As we use libc for syscalls on darwin, we need to save the G register before the libc call. Otherwise it is not signal-safe, as a signal may land during the execution of a libc function, where the G register may be clobbered. This CL initializes TLS in Go, by calling the pthread functions directly without cgo. This makes it possible to save the G register to TLS in pure Go programs (done in a later CL). Inspired by Elias's CL 209197. Write the logic in Go instead of assembly. Updates #38485, #35853.

2019-06-30runtime: use a pipe to wake up signal_recv on DarwinIan Lance Taylor
The implementation of semaphores, and therefore notes, used on Darwin is not async-signal-safe. The runtime has one case where a note needs to be woken up from a signal handler: the call to notewakeup in sigsend. That notewakeup call is only called on a single note, and it doesn't need the full functionality of notes: nothing ever does a timed wait on it. So change that one note to use a different implementation on Darwin, based on a pipe. This lets the wakeup code use the write call, which is async-signal-safe.

2018-06-25runtime: respect timeout in semasleep on DarwinNikhil Benesch
semasleep on Darwin was refactored in https://golang.org/cl/118736 to use the pthread_cond_timedwait function from libc. The new code incorrectly assumed that pthread_cond_timedwait took a timeout relative to the current time, when it in fact it takes a timeout specified in absolute time. semasleep thus specified a timeout well in the past, causing it to immediately exceed the timeout and spin hot. This was the source of a large performance hit to CockroachDB (#26019). Adjust semasleep to instead call pthread_cond_timedwait_relative_np, which properly interprets its timeout parameter as relative to the current time. pthread_cond_timedwait_relative_np is non-portable, but using pthread_cond_timedwait correctly would require two calls to gettimeofday: one in the runtime package to convert the relative timeout to absolute time, then another in the pthread library to convert back to a relative offset [0], as the Darwin kernel expects a relative offset.

2017-10-11runtime: make it possible to exit Go-created threadsAustin Clements
Currently, threads created by the runtime exist until the whole program exits. For #14592 and #20395, we want to be able to exit and clean up threads created by the runtime. This commit implements that mechanism. The main difficulty is how to clean up the g0 stack. In cgo mode and on Solaris and Windows where the OS manages thread stacks, we simply arrange to return from mstart and let the system clean up the thread. If the runtime allocated the g0 stack, then we use a new exitThread syscall wrapper that arranges to clear a flag in the M once the stack can safely be reaped and call the thread termination syscall. exitThread is based on the existing exit1 wrapper, which was always meant to terminate the calling thread. However, exit1 has never been used since it was introduced 9 years ago, so it was broken on several platforms. exitThread also has the additional complication of having to flag that the stack is unused, which requires some tricks on platforms that use the stack for syscalls. This still leaves the problem of how to reap the unused g0 stacks. For this, we move the M from allm to a new freem list as part of the M exiting. Later, allocm scans the freem list, finds Ms that are marked as done with their stack, removes these from the list and frees their g0 stacks. This also allows these Ms to be garbage collected. This CL does not yet use any of this functionality. Follow-up CLs will. Likewise, there are no new tests in this CL because we'll need follow-up functionality to test it.
