commit 8e5a7a7d9ebc47bfbde6b1463e0e146a7eaa247e Author: Karsten Loesing karsten.loesing@gmx.net Date: Wed Nov 7 12:04:02 2012 -0500
Make five modules executable on their own.
This will prevent one failing module from breaking the other four. It will also make it easier to change the timing of execution. --- .gitignore | 2 +- bin/run-bridgedescs | 5 + bin/run-bridgepools | 5 + bin/run-exitlists | 5 + bin/run-relaydescs | 5 + bin/run-torperf | 5 + build.xml | 44 ++++++++-- run.sh | 5 - .../db/bridgedescs/SanitizedBridgesWriter.java | 39 ++++++++-- .../BridgePoolAssignmentsProcessor.java | 38 ++++++++-- .../ernie/db/exitlists/ExitListDownloader.java | 37 +++++++-- src/org/torproject/ernie/db/main/LockFile.java | 11 ++- .../ernie/db/main/LoggingConfiguration.java | 7 +- src/org/torproject/ernie/db/main/Main.java | 85 -------------------- .../ernie/db/relaydescs/ArchiveWriter.java | 31 +++++++ .../ernie/db/torperf/TorperfDownloader.java | 37 +++++++-- 16 files changed, 232 insertions(+), 129 deletions(-)
