[roll] Roll fuchsia [starnix][binder] Improve reference counting The reference counting implementation now correctly tracks weak and strong references to binder objects in the handle table. An object is kept in the handle table until all references, weak and strong, are released. The underlying object it points to may be dead earlier, however. When a transaction occurs, any binder objects inside the buffer have a strong reference taken by the kernel, and that reference is dropped when the buffer is freed with a BC_FREE_BUFFER command. Weak references are tracked, but they aren't communicated to the owning process. Android doesn't support sending weak references, then upgrading them to strong references. There was work in the kernel to support this supposedly, but userspace never implemented it and the APIs were deprecated and removed.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
