nickhill f164759ea3 Support composite buffer creation without array alloc and copy ... Motivation: Unpooled.unmodifiableBuffer() is currently used to efficiently write arrays of ByteBufs via FixedCompositeByteBuf, but involves an allocation and content-copy of the provided ByteBuf array which in many (most?) cases shouldn't be necessary. Modifications: Modify the internal FixedCompositeByteBuf class to support wrapping the provided ByteBuf array directly. Control this behaviour with a constructor flag and expose the "unsafe" version via a new Unpooled.wrappedUnmodifiableBuffer(ByteBuf...) method. Result: Less garbage on IO paths. I would guess pretty much all existing usage of unmodifiableBuffer() could use the copy-free version but assume it's not safe to change its default behaviour.		2018-06-27 07:40:14 +02:00
