This is *very* bad. - * - * I.e. we should take a conservative approach, and only set non- - * blocking mode when we a) need to, and b) are reasonably certain - * that it won't be a problem. And as in the example above, the problem - * occurs when input fd and output fd point to different "things". - * - * However, determining that they are not just the same "type" of - * "thing", but actually the same instance of that type of thing, is - * unreasonably complex in many/most cases. - * - * Also, with pipes, sockets, and fifos it's far from obvious that the - * user *wants* non-blocking output: If you're running erlang inside - * some complex pipeline, you're probably not running a real-time system - * that must never stop, but rather *want* it to suspend if the output - * channel is "full". - * - * So, the bottom line: We will only set the output fd non-blocking if - * it points to a tty, and either a) the input fd also points to a tty, - * or b) we can make sure that setting the output fd non-blocking - * doesn't interfere with someone else's input, via a somewhat milder - * kludge than the above. - * - * Also keep in mind that while this code is almost exclusively run as - * a result of an erlang open_port({fd,0,1}, ...), that isn't the only - * case - it can be called with any old pre-existing file descriptors, - * the relations between which (if they're even two) we can only guess - * at - still, we try our best... - * - * Added note OTP 18: Some systems seem to use stdout/stderr to log data - * using unix pipes, so we cannot allow the system to block on a write. - * Therefore we use an async thread to write the data to fd's that could - * not be set to non-blocking. When no async threads are available we - * fall back on the old behaviour. - * - * Also the guarantee about what is delivered to the OS has changed. - * Pre 18 the fd driver did no flushing of data before terminating. - * Now it does. This is because we want to be able to guarantee that things - * such as escripts and friends really have outputted all data before - * terminating.

This is *very* bad. + * + * I.e. we should take a conservative approach, and only set non- + * blocking mode when we a) need to, and b) are reasonably certain + * that it won't be a problem. And as in the example above, the problem + * occurs when input fd and output fd point to different "things". + * + * However, determining that they are not just the same "type" of + * "thing", but actually the same instance of that type of thing, is + * unreasonably complex in many/most cases. + * + * Also, with pipes, sockets, and fifos it's far from obvious that the + * user *wants* non-blocking output: If you're running erlang inside + * some complex pipeline, you're probably not running a real-time system + * that must never stop, but rather *want* it to suspend if the output + * channel is "full". + * + * So, the bottom line: We will only set the output fd non-blocking if + * it points to a tty, and either a) the input fd also points to a tty, + * or b) we can make sure that setting the output fd non-blocking + * doesn't interfere with someone else's input, via a somewhat milder + * kludge than the above. + * + * Also keep in mind that while this code is almost exclusively run as + * a result of an erlang open_port({fd,0,1}, ...), that isn't the only + * case - it can be called with any old pre-existing file descriptors, + * the relations between which (if they're even two) we can only guess + * at - still, we try our best... + * + * Added note OTP 18: Some systems seem to use stdout/stderr to log data + * using unix pipes, so we cannot allow the system to block on a write. + * Therefore we use an async thread to write the data to fd's that could + * not be set to non-blocking. When no async threads are available we + * fall back on the old behaviour. + * + * Also the guarantee about what is delivered to the OS has changed. + * Pre 18 the fd driver did no flushing of data before terminating. + * Now it does. This is because we want to be able to guarantee that things + * such as escripts and friends really have outputted all data before + * terminating.
