can we somehow distinguish between line-to-long to some other errors where we actually want to exit.

Thanks, should be handled better now 👍

Is it possible to do some benchmarks vs the regular scanner just to see that we are not eating cpu/memory in comparison to the built-in scanner (given it can be quite intensive)? |

@yevgenypats I added some benchmarks: A tiny bit slower than BufferedScanner in this test (but we're talking nanoseconds here) and no additional allocs. |

This fixes an issue where the CLI would hang indefinitely when it encountered a log line from a plugin that was longer than the buffer size allowed for by
bufio.Scanner. The fix uses a wrapper aroundbufio.NewReaderto skip lines that are too long to be parsed, printing an error in the log with the first 1000 characters to help with identification.
