[tor-commits] [tor/master] Change EVENT_TRANSPORT_LOG to EVENT_PT_LOG.
commit ec2ae3ed8b542950dc774223607f14f524375a50
Author: Alexander Færøy <ahf@xxxxxxxxxxxxxx>
Date: Thu Nov 29 16:42:56 2018 +0100
Change EVENT_TRANSPORT_LOG to EVENT_PT_LOG.
This patch changes our EVENT_TRANSPORT_LOG event to be EVENT_PT_LOG. The
new message includes the path to the PT executable instead of the
transport name, since one PT binary can include multiple transport they
sometimes might need to log messages that are not specific to a given
transport.
See: https://bugs.torproject.org/28179
