* This acts as an optimization barrier, limiting the rewriting allowed
* For now this forbids all optimization, but attributes can be added to
opt in to specific optimizations as required
When `run_command` reads subprocess output via `fgets` in a multi-threaded process, incoming signals can interrupt the underlying `read` syscall with `EINTR`. Previously, `while (fgets(...) != NULL)` exited the read loop immediately on `EINTR` and called `pclose`, closing the pipe early while the child was still running (or causing the child to die with `SIGPIPE`). Additionally, `run_command` returned `WEXITSTATUS(ret)` without checking `WIFEXITED(ret)`, which evaluates to `0` when a child terminates due to an unhandled signal.
Retry `fgets` after clearing the stream error state when `ferror(f) && errno == EINTR`, and return `-1` if `!WIFEXITED(ret)`.
