From 0e45136a44feead58a7f28c99c58e6c39938c0f9 Mon Sep 17 00:00:00 2001 From: Aikar Date: Wed, 9 Jan 2013 22:18:26 -0500 Subject: [PATCH] Improved Timings System Enables "Timings on Demand" so you can enable/disable timings without server restart. Tracks timings on sync events a plugin registers (Single and Repeating) Tracks how many ticks a timed area has caused the server to lose due to taking too long. Enables automatically pasting to paste.ubuntu.com so you can quickly review the results on aikar.co/timings.php --- src/main/java/org/bukkit/CustomTimingsHandler.java | 134 +++++++++++++++++++++ .../org/bukkit/command/defaults/ReloadCommand.java | 2 + .../bukkit/command/defaults/TimingsCommand.java | 90 ++++++++++++-- .../org/bukkit/plugin/TimedRegisteredListener.java | 12 +- .../org/bukkit/plugin/java/JavaPluginLoader.java | 2 +- 5 files changed, 227 insertions(+), 13 deletions(-) create mode 100644 src/main/java/org/bukkit/CustomTimingsHandler.java diff --git a/src/main/java/org/bukkit/CustomTimingsHandler.java b/src/main/java/org/bukkit/CustomTimingsHandler.java new file mode 100644 index 0000000..8c00824 --- /dev/null +++ b/src/main/java/org/bukkit/CustomTimingsHandler.java @@ -0,0 +1,134 @@ +package org.bukkit;
