[collector/release] Handle bridge descriptors with unusual line order.
by karsten＠torproject.org 26 Oct '17

commit a38f7c277142e5300f3d7f43567b38706d727010 Author: Karsten Loesing <karsten.loesing(a)gmx.net> Date: Wed Oct 25 17:29:40 2017 +0200 Handle bridge descriptors with unusual line order. Typically, the "published" line appears before the "fingerprint" line. However, an alternative Tor implementation orders these two lines differently, which is valid due to the spec. We need to handle this case by accepting lines in either order.
