Is there a way to go about killing a process after spawning it on a
SIGINT?
I can't do this for e.g. because kill is not @nogc.
Pid currentSpawnedPid;
extern(C) void killCurrentPidHandler(int sig) nothrow @nogc @system {
kill(currentSpawnedPid, sig);
}
int main() {
currentSpawnedPid = spawnProcess(["docker-compose", "up"], stdin,
stdout, stderr);
signal(SIGINT, &killCurrentPidHandler);
return wait(currentSpawnedPid);
}
Any other ways to go about this?
Yeah, fix phobos. kill should be @nogc/nothrow, and probably @safe.
Looked in to it, seems step one is getting phobos compiling with dip1008 :/
Kill uses enforce.
Oof, yeah. I saw the short kill function and thought it was simply
calling the kill syscall, but it's calling something more complex. Error
handling in general in Phobos is somewhat of a mixed bag. Would be great
to have a clearly defined error handling scheme, or even one that's
configurable.
Or as you said, make dip1008 mandatory ;)
