From fc65820f9e9a9a39434bbef3f5e9251436d9b458 Mon Sep 17 00:00:00 2001 From: Ivan Alejandro Date: Thu, 25 Jun 2015 19:57:52 -0300 Subject: [bug] log contains exported PGP private key Due to #7139 (the logbook log centralizer) logs from 3rd party libs are included in the centralized logs with lots of debug information and we don't want that. We use the existing silencer to exclude logs that are not from leap modules. - Resolves: #7185 --- src/leap/bitmask/logs/log_silencer.py | 82 ++++++++++++++++++++++++----------- 1 file changed, 56 insertions(+), 26 deletions(-) (limited to 'src/leap/bitmask') diff --git a/src/leap/bitmask/logs/log_silencer.py b/src/leap/bitmask/logs/log_silencer.py index 540532cb..da95e9b1 100644 --- a/src/leap/bitmask/logs/log_silencer.py +++ b/src/leap/bitmask/logs/log_silencer.py @@ -18,24 +18,31 @@ Filter for leap logs.
