Go to file
Adam Simpkins fed342da30 store overlay files using inode numbers instead of paths 
Summary:
Refactor the Overlay code to store data using inode numbers rather than the
affected file's path in the repository.  This simplifies the TreeInode code a
bit, as we no longer have to rename overlay files to stay in sync with the file
paths.  This also eliminates some crashes when trying to update overlay files
for inodes that have been unlinked (and hence no longer have a path).  This
also includes a few fixes to avoid writing journal entries for unlinked files
too.  Additionally this contains a few fixes to how mode bits are stored in the
overlay, and fixes a bug where create() was ignoring the mode argument.

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.
