commit d9f44fabf0922f1d76a6d313b42ef7ed61ce4977 Author: Isis Lovecruft isis@torproject.org Date: Sat Mar 28 02:38:42 2015 +0000
Fix bug in proxy.loadProxiesFromFile().
Checking `if proxySet` when the ProxySet was empty (as at server startup, particularly when loading the PROXY_LIST_FILES), would evaluate to False, cause the proxies from the files *not* to be loaded into the empty ProxySet.
This did not effect loading the list of Tor Exit relays, since we use scripts/get-tor-exits and load the list into memory while calling ProxySet.add() for each one (rather than loading Tor Exit relays from a downloaded file, like we used to do). --- lib/bridgedb/proxy.py | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-)
