Comment (by mikeperry):
Ok nice catch on the review. I fixed that double-logic bug and squashed
everything down: https://github.com/mikeperry-
tor/tor/tree/bug30992%2B32040
Note that I stripped down the apply_purpose_mask for intro circs to *only*
include C_INTRODUCING, as this should be the first and only purpose we
want to actually *start* machines for, right? We should not try to jump
into the other purposes to apply a fresh machine, but we should keep an
old run around for:
https://github.com/mikeperry-
tor/tor/commit/551ccc95fb242e27477ec5fcbf0af32a4b0ce761
Is C_INTRODUCING the right start purpose? Or can intro circuits jump in
fully formed at later purposes?
Do we want to do the same thing to rends for symmetry?
