commit 813edcdb7df8de97a11e6ff9bb0eb7ad267532bf Author: iwakeh iwakeh@torproject.org Date: Fri Sep 30 12:05:39 2016 +0200
Added runTest() and assert stmt to testTarballContainsSameFileTwice. Switched to use of java.nio.file package methods. Make DescriptorBuilder extend ArrayList saves a few characters throughout the builders. --- .../collector/bridgedescs/DescriptorBuilder.java | 33 +++--- .../bridgedescs/ExtraInfoDescriptorBuilder.java | 2 +- .../bridgedescs/NetworkStatusBuilder.java | 2 +- .../bridgedescs/SanitizedBridgesWriterTest.java | 126 ++++++++++----------- .../bridgedescs/ServerDescriptorBuilder.java | 2 +- 5 files changed, 74 insertions(+), 91 deletions(-)
