From 18765a3bf7bf85b541897bc9b3dd8e0c57482614 Mon Sep 17 00:00:00 2001 From: Norman Maurer Date: Tue, 12 Jan 2016 15:06:30 +0100 Subject: [PATCH] [#4017] Implement proper resource leak detection for CompositeByteBuf Motivation: CompositeByteBuf only implemented simple resource leak detection and how it was implemented was completly different to the way it was for ByteBuf. The other problem was that slice(), duplicate() and others would not return a resource leak enabled buffer. Modifications: - Proper implementation for all level of resource leak detection for CompositeByteBuf Result: Proper resource leak detection for CompositeByteBuf. --- .../buffer/AbstractByteBufAllocator.java | 28 +- .../AbstractReferenceCountedByteBuf.java | 6 +- .../buffer/AdvancedLeakAwareByteBuf.java | 218 ++-- .../AdvancedLeakAwareCompositeByteBuf.java | 806 ++++++++++++++ .../io/netty/buffer/CompositeByteBuf.java | 28 +- .../SimpleLeakAwareCompositeByteBuf.java | 79 ++ .../main/java/io/netty/buffer/Unpooled.java | 8 +- .../netty/buffer/WrappedCompositeByteBuf.java | 994 ++++++++++++++++++ 8 files changed, 2038 insertions(+), 129 deletions(-) create mode 100644 buffer/src/main/java/io/netty/buffer/AdvancedLeakAwareCompositeByteBuf.java create mode 100644 buffer/src/main/java/io/netty/buffer/SimpleLeakAwareCompositeByteBuf.java create mode 100644 buffer/src/main/java/io/netty/buffer/WrappedCompositeByteBuf.java diff --git a/buffer/src/main/java/io/netty/buffer/AbstractByteBufAllocator.java b/buffer/src/main/java/io/netty/buffer/AbstractByteBufAllocator.java index 34e5d2c6dd4..eb445e17f27 100644 --- a/buffer/src/main/java/io/netty/buffer/AbstractByteBufAllocator.java +++ b/buffer/src/main/java/io/netty/buffer/AbstractByteBufAllocator.java @@ -26,7 +26,7 @@ */ public abstract class AbstractByteBufAllocator implements ByteBufAllocator { private static final int DEFAULT_INITIAL_CAPACITY = 256;
