Chad Austin 5f5b317e8b release blob memory when last file handle is closed 
Summary:
Today, if a file is ever opened for read, each FileInode keeps a copy
of the data as long as the FileInode is around.  This results in
excessive memory consumption under common mistakes like repo-wide grep
or `hg revert .`.

I will audit all of the state machine transitions and blob accesses
before landing this diff.

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.
