commit 4d4d75fdc57de91ae6796341468811d061e82c9c Author: Damian Johnson atagar@torproject.org Date: Sat Nov 10 16:58:37 2018 -0800
Only use directory mirrors with a DirPort
Oops! Iirc the V2Dir flag once was only granted to relays with a DirPort but seems that's no longer the case. As a result our use_directory_mirrors() method inserted endpoints with port values of 'None'...

We could use their ORPort to download descriptors instead, but Stem's ORPort capabilities are still pretty immature so just gonna restrict ourselves to DirPort mirrors for now instead. --- docs/change_log.rst | 1 + stem/descriptor/remote.py | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-)
