* all: remove the nacl port (part 1)Brad Fitzpatrick2019-10-091-1/+1
| | | | | | | | | | | | | | | | | | You were a useful port and you've served your purpose. Thanks for all the play. A subsequent CL will remove amd64p32 (including assembly files and toolchain bits) and remaining bits. The amd64p32 removal will be separated into its own CL in case we want to support the Linux x32 ABI in the future and want our old amd64p32 support as a starting point.

* os: on GNU/Linux use waitid to avoid wait/kill raceIan Lance Taylor2016-06-101-0/+16
On systems that support the POSIX.1-2008 waitid function, we can use it to block until a wait will succeed. This avoids a possible race condition: if a program calls p.Kill/p.Signal and p.Wait from two different goroutines, then it is possible for the wait to complete just before the signal is sent. In that case, it is possible that the system will start a new process using the same PID between the wait and the signal, causing the signal to be sent to the wrong process. The Process.isdone field attempts to avoid that race, but there is a small gap of time between when wait returns and isdone is set when the race can occur. This CL avoids that race by using waitid to wait until the process has exited without actually collecting the PID. Then it sets isdone, then waits for any active signals to complete, and only then collects the PID. No test because any plausible test would require starting enough processes to recycle all the process IDs. Update #13987. Update #16028.
