[node-dev] Porting fs to the browser / process.binding('fs') & process.binding('constants')

[Adam Crabtree]

Howdy all,

(Let me know if this isn't appropriate for nodejs-dev.)

I'm attempting to porting fs to the browser in browserify via the
FileSystem API, and it looks like the fastest route is to shim the
appropriate process.binding('fs') and process.binding('constants'), which
includes:

// from process.binding('fs')
[ 'Stats',
  'close',
  'open',
  'read',
  'fdatasync',
  'fsync',
  'rename',
  'truncate',
  'rmdir',
  'mkdir',
  'sendfile',
  'readdir',
  'stat',
  'lstat',
  'fstat',
  'link',
  'symlink',
  'readlink',
  'unlink',
  'write',
  'chmod',
  'fchmod',
  'chown',
  'fchown',
  'utimes',
  'futimes',
  'StatWatcher' ]

// from process.binding('constants')
{
O_RDONLY: 0,
  O_WRONLY: 1,
  O_RDWR: 2,
  S_IFMT: 61440,
  S_IFREG: 32768,
  S_IFDIR: 16384,
  S_IFCHR: 8192,
  S_IFBLK: 24576,
  S_IFIFO: 4096,
  S_IFLNK: 40960,
  S_IFSOCK: 49152,
  O_CREAT: 512,
  O_EXCL: 2048,
  O_NOCTTY: 131072,
  O_TRUNC: 1024,
  O_APPEND: 8,
  O_DIRECTORY: 1048576,
  O_NOFOLLOW: 256,
  O_SYNC: 128,
  O_SYMLINK: 2097152
}

The fs bindings seem pretty straightforward, not sure if they'll all
translate to the FileSystem API, but mostly if anyone would be be willing
to give information on the constants I'd be very thankful.

Also, are these documented outside of the source?

Cheers,
Adam Crabtree
