Yeah, I am not too surprised. The failing helper sleeps before exiting so that fast-export puts all of its data into the pipe buffer before the helper dies, and does not get SIGPIPE. But obviously the sleep is just delaying the problem if your fast-export runs really slowly (which, if you are running under valgrind, is a possibility). The helper should instead just consume all of fast-export's input before exiting, which accomplishes the same thing, finishes sooner in the normal case, and doesn't race. And I think it also simulates a reasonable real-world setup (a helper reads and converts the data, but then dies while writing the output to disk, the network, or whatever). I posted review comments, including that, and I'm assuming that Felipe is going to re-roll at some point. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
