URL: https://github.com/llvm/llvm-project/commit/1ff4b503802b049463da4a8fd4aaac496ddd260b DIFF: https://github.com/llvm/llvm-project/commit/1ff4b503802b049463da4a8fd4aaac496ddd260b.diff LOG: [lldb] Quit automatically if --batch has no commands to run (#179969) Fixes #179700 Simple fix, if we are in batch mode, don't go into an interactive session after checking if there are commands to run. Testing it is more tricky. I tried a shell test as I thought it would be simplest. However to be able to FileCheck I had to pipe and the pipe turns off the prompt because it's non-interactive. The prompt is the thing that must not be printed. So I've just spawned lldb as a subprocess. If it doesn't quit quickly then something is wrong. The timeout is high not because it should normally take that long, but because sometimes a process will get stalled for a while and I don't want this to be flaky. (though in theory it can get stalled for much longer than a minute) If it does time out, the process will be cleaned up automatically. See https://docs.python.org/3/library/subprocess.html#subprocess.run > A timeout may be specified in seconds, it is internally > passed on to Popen.communicate(). If the timeout expires, > the child process will be killed and waited for.
