Chad Austin d986fed38c always unload trees prior to checkout 
Summary:
The checkout operation is a bit hamstrung, performance-wise, when
inodes are loaded. If it's possible the kernel has a reference to an
inode, we can't short-circuit the checkout operation and instead must
precisely add and remove children from the source control tree and
persist the new children and inode numbers into the overlay.

It's much faster if we treat checkout as an inode-number-invalidating
change and unload all inodes that aren't referenced by the kernel.

Eden

Eden is a project with several components, the most prominent of which is a virtual filesystem built using FUSE.

Caveat Emptor

Eden is still in early stages of development. We are making it available now because we plan to start making references to it from our other open source projects, such as Buck, Watchman, and Nuclide.

The version that we provide on GitHub does not build yet.

This is because the code is exported verbatim from an internal repository at Facebook, and not all of the scaffolding from our internal repository can be easily extracted. The key areas where we need to shore things up are:

  • The reinterpretations of build macros in DEFS.
  • A process for including third-party dependencies (presumably via Git submodules) and wiring up the external_deps argument in the build macros to point to them.
  • Providing the toolchain needed to power the [undocumented] thrift_library() rule in Buck.

The goal is to get Eden building on both Linux and OS X, though Linux support is expected to come first.
