commit 5e2bc2229eafc81cc26c46529ed812add14a66f2 Author: Damian Johnson <atagar@torproject.org> Date: Thu Apr 26 19:31:24 2012 -0700 Circuits wouldn't be updated when connection resolution failed The connecion panel provides information from two sources: connections from system utilities and circuits from tor. We had a check that prevented the connection panel from being updated when the former didn't have any new information, which in turn broke the panel entirely when connection resolvers either failed or were disabled. The 'is new connecion results available' check was actually pretty pointless. The update method gets called every five seconds and the connection resolvers operate at a similar rate (maybe every ten seconds? it depends on resolver performance) so it didn't actually buy us much. Removed the check. --- src/cli/connections/connPanel.py | 193 +++++++++++++++++++------------------- 1 files changed, 96 insertions(+), 97 deletions(-) diff --git a/src/cli/connections/connPanel.py b/src/cli/connections/connPanel.py index d108252..cf7823a 100644 --- a/src/cli/connections/connPanel.py +++ b/src/cli/connections/connPanel.py @@ -419,105 +419,104 @@ class ConnectionPanel(panel.Panel, threading.Thread): connResolver = connections.getResolver("tor") currentResolutionCount = connResolver.getResolutionCount() - if self._lastResourceFetch != currentResolutionCount: - self.valsLock.acquire() - - newEntries = [] # the new results we'll display - - # Fetches new connections and client circuits... - # newConnections [(local ip, local port, foreign ip, foreign port)...] - # newCircuits {circuitID => (status, purpose, path)...} - - newConnections = connResolver.getConnections() - newCircuits = {} - - for circuitID, status, purpose, path in torTools.getConn().getCircuits(): - # Skips established single-hop circuits (these are for directory - # fetches, not client circuits) - if not (status == "BUILT" and len(path) == 1): - newCircuits[circuitID] = (status, purpose, path) - - # Populates newEntries with any of our old entries that still exist. - # This is both for performance and to keep from resetting the uptime - # attributes.
