[tor-commits] [tor/master] Lower dir fetch retry schedules in testing networks.
commit 1293835440dd4debf6fbfc66e755d9b9384aa362
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date: Thu May 16 12:08:48 2013 +0200
Lower dir fetch retry schedules in testing networks.
Also lower maximum interval without directory requests, and raise
maximum download tries.
Implements #6752.
