[tor-bugs] #6769 [Tor Relay]: Relays (and bridges) don't use microdescriptors
#6769: Relays (and bridges) don't use microdescriptors
-----------------------+----------------------------------------------------
Reporter: arma | Owner:
Type: defect | Status: new
Priority: normal | Milestone: Tor: 0.2.4.x-final
Component: Tor Relay | Version:
Keywords: | Parent:
Points: | Actualpoints:
-----------------------+----------------------------------------------------
In we_use_microdescriptors_for_circuits() we return
{{{
!server_mode(options) && !options->FetchUselessDescriptors;
}}}
So if you're a relay, even if you don't otherwise cache dir info, you end
up fetching and using old-style descriptors rather than microdescriptors.
This decision has a minor effect on bootstrapping, where we won't build
circuits until we have the full set of old-style consensus-and-
descriptors, so e.g. time_to_try_getting_descriptors in main.c is dictated
at that point by LAZY_DESCRIPTOR_RETRY_INTERVAL even if we don't have much
of the microdesc info.
The decision has a larger effect on bridges, which fetch and use normal
descriptors -- over time they will diverge even more from normal client
behavior.
