Rebased on dev after the 0.42.0 release. The change applies on top of v0.42.0 |
Use posix_spawn on hosted Linux and Darwin. Map process files, apply the working directory and process group, and clear the child signal mask. Use wait4 for process status and support Kill and Signal. Mark Darwin pipes close-on-exec under ForkLock. Darwin also needs the fcntl wrapper in PR tinygo-org#5612 and the libSystem symbols in PR tinygo-org#5636. Concurrent spawn and pipe creation need the RWMutex fix in PR tinygo-org#5630. Keep the process stubs on other targets and add process regression tests.

Open /dev/null in the child before closing a nil or unnamed descriptor. Save remap sources before these actions. This avoids a parent descriptor check and its race with concurrent open. Use descriptor reads and exec redirection in remap tests. Check nil slots and temporary descriptors. The tests pass with ordinary Go on Darwin and Linux. Both TinyGo os suites pass with released compiler source overlays. Darwin also needs the addopen symbol from PR tinygo-org#5636.
