Adam Simpkins 0928e2af18 ensure that we send no more than IOV_MAX iovecs at once 
Summary:
Update the UnixSocket code to limit the number of iovecs that we send at one
time to folly::kIovMax.  (This constant is set from from IOV_MAX on platforms
that provide this setting.)

The thrift serializer code emits data into 16kB chunks, so if we had many
megabytes of data to send we could end up with thousands of iovecs.  The kernel
would fail the send with EMSGSIZE in this case.

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.
