From aad2273ca0fda70abb966f5b7687acec79892521 Mon Sep 17 00:00:00 2001 From: Alva Swanson Date: Wed, 15 Feb 2023 18:38:15 +0100 Subject: [PATCH] Implement NetworkStatisticsService The NetworkStatisticsService is an attempt to decouple the network statistic computation from the UI thread. Here, the NetworkStatisticsService schedules repeating tasks on a ScheduledExecutorService. --- .../statistics/ConnectionStatistics.java | 111 +++++++ .../ConnectionStatsAccumulator.java | 75 +++++ .../network/statistics/NetworkStatistics.java | 29 ++ .../statistics/NetworkStatisticsService.java | 116 +++++++ .../statistics/ConnectionStatisticsTest.java | 306 ++++++++++++++++++ .../ConnectionStatsAccumulatorTest.java | 140 ++++++++ 6 files changed, 777 insertions(+) create mode 100644 p2p/src/main/java/bisq/network/p2p/network/statistics/ConnectionStatistics.java create mode 100644 p2p/src/main/java/bisq/network/p2p/network/statistics/ConnectionStatsAccumulator.java create mode 100644 p2p/src/main/java/bisq/network/p2p/network/statistics/NetworkStatistics.java create mode 100644 p2p/src/main/java/bisq/network/p2p/network/statistics/NetworkStatisticsService.java create mode 100644 p2p/src/test/java/bisq/network/p2p/network/statistics/ConnectionStatisticsTest.java create mode 100644 p2p/src/test/java/bisq/network/p2p/network/statistics/ConnectionStatsAccumulatorTest.java diff --git a/p2p/src/main/java/bisq/network/p2p/network/statistics/ConnectionStatistics.java b/p2p/src/main/java/bisq/network/p2p/network/statistics/ConnectionStatistics.java new file mode 100644 index 00000000000..7918696d05e --- /dev/null +++ b/p2p/src/main/java/bisq/network/p2p/network/statistics/ConnectionStatistics.java @@ -0,0 +1,111 @@ +/* + * This file is part of Bisq. + * + * Bisq is free software: you can redistribute it and/or modify it + * under the terms of the GNU Affero General Public License as published by + * the Free Software Foundation, either version 3 of the License, or (at + * your option) any later version. + * + * Bisq is distributed in the hope that it will be useful, but WITHOUT + * ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or + * FITNESS FOR A PARTICULAR PURPOSE.
