commit b69544ba095710c4b8a6b38c4a965b668b1b8717 Author: Damian Johnson atagar@torproject.org Date: Tue Mar 14 13:46:09 2017 -0700

Simplify assertion that descriptor ends with router-sig-ed25519

The spec says 'next-to-last' but we allow it to be at the end too. Not quite sure why, maybe related to sanitized bridge descriptors? Anywho, might as well combine these two conditionals into one and fix the message. --- stem/descriptor/server_descriptor.py | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-)
