This should now be testable, right? |

Rather the tests were written elsewhere with a different patch. This is now rebased and ready for review. |

the case with no core samples fails... |

Of course I reviewed #4052, but what basis did we have for thinking I've made that test more certain. |

Sorry, that was a hacky test. It probably came from some example that was failing at the time. |

There was a problem hiding this comment.
Maybe a stupid question but why do you need [1] twice?

#3994 handled the
min_samplesboundary case differently to the prior DBSCAN implementation. This is now clarified in the docs. Unfortunately, when properly testing boundary cases, I found the inconsistency reported at #4072. I fix it here for 'brute' search without tests, pending a complete patch for #4072.
