[roll] Roll fuchsia [fidl-connector] parking_lot -> fuchsia-sync parking_lot has a few disadvantages for Fuchsia: * adaptive spin w/ thread yields is great for microbenchmarks but has poor system-wide interactions with interrupts and the scheduler * the parking lot abstraction doesn't convey priority inheritance * implicit heap allocations make it unsuitable for use cases like instrumentation code By contrast, fuchsia-sync is built directly on top of our libsync and Zircon futexes. It tends to perform slightly worse on microbenchmarks because it lacks an adaptive spin but feedback from the kernel team is that we should see better whole-system performance with this implementation. It's also possible that changing synchronization strategies will surface new test flakes in code with latent timing bugs.

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.
