commit a0ce8664bc5758030c912456fcf2ff33a619373f Author: Damian Johnson atagar@torproject.org Date: Mon Oct 7 22:11:44 2013 -0700
Storing a single IPv6 default exit policy
Each server descriptor constructed its own default value for the IPv6 exit policy, which was foolish. ExitPolicy instances are read-only instances, so all descriptors might as well use the same default. This saves roughly 2.3 MB of memory when downloading all of the current server descriptors (or roughly 3%). --- stem/descriptor/server_descriptor.py | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-)
