class Chef
module ChefFS
#
# Translation layer between chef-zero's DataStore (a place where it expects
# files to be stored) and ChefFS (the user's repository directory layout).
#
# chef-zero expects the data store to store files *its* way--for example, it
# expects get("nodes/blah") to return the JSON text for the blah node, and
# it expects get("cookbooks/blah/1.0.0") to return the JSON definition of
# the blah cookbook version 1.0.0.
#
# The repository is defined the way the *user* wants their layout. These
# two things are very similar in layout (for example, nodes are stored under
# the nodes/ directory and their filename is the name of the node).
#
# However, there are a few differences that make this more than just a raw
# file store:
#
# 1. Cookbooks are stored much differently.
# - chef-zero places JSON text with the checksums for the cookbook at
# /cookbooks/NAME/VERSION, and expects the JSON to contain URLs to the
# actual files, which are stored elsewhere.
# - The repository contains an actual directory with just the cookbook
# files and a metadata.rb containing a version #. There is no JSON to
# be found.
# - Further, if versioned_cookbooks is false, that directory is named
# /cookbooks/NAME and only one version exists. If versioned_cookbooks
# is true, the directory is named /cookbooks/NAME-VERSION.
# - Therefore, ChefFSDataStore calculates the cookbook JSON by looking at
# the files in the cookbook and checksumming them, and reading metadata.rb
# for the version and dependency information.
# - ChefFSDataStore also modifies the cookbook file URLs so that they point
# to /file_store/repo/<filename> (the path to the actual file under the
# repository root). For example, /file_store/repo/apache2/metadata.rb or
# /file_store/repo/cookbooks/apache2/recipes/default.rb).
#
# 2. Sandboxes don't exist in the repository.
# - ChefFSDataStore lets cookbooks be uploaded into a temporary memory
# storage, and when the cookbook is committed, copies the files onto the
# disk in the correct place (/cookbooks/apache2/recipes/default.rb).
#
# 3. Data bags:
# - The Chef server expects data bags in /data/BAG/ITEM
# - The repository stores data bags in /data_bags/BAG/ITEM
#
# 4. JSON filenames are generally NAME.json in the repository (e.g. /nodes/foo.json).
#
# 5. Org membership:
# chef-zero stores user membership in an org as a series of empty files.
# If an org has jkeiser and cdoherty as members, chef-zero expects these
# files to exist:
#
# - `users/jkeiser` (content: '{}')
# - `users/cdoherty` (content: '{}')
#
# ChefFS, on the other hand, stores user membership in an org as a single
# file, `members.json`, with content:
#
# ```json
# [
# { "user": { "username": "jkeiser" } },
# { "user": { "username": "cdoherty" } }
# ]
# ```
#
# To translate between the two, we need to intercept requests to `users`
# like so:
#
# - `list(users)` -> `get(/members.json)`
# - `get(users/NAME)` -> `get(/members.json)`, see if it's in there
# - `create(users/NAME)` -> `get(/members.json)`, add name, `set(/members.json)`
# - `delete(users/NAME)` -> `get(/members.json)`, remove name, `set(/members.json)`
#
# 6. Org invitations:
# chef-zero stores org membership invitations as a series of empty files.
# If an org has invited jkeiser and cdoherty (and they have not yet accepted
# the invite), chef-zero expects these files to exist:
#
# - `association_requests/jkeiser` (content: '{}')
# - `association_requests/cdoherty` (content: '{}')
#
# ChefFS, on the other hand, stores invitations as a single file,
# `invitations.json`, with content:
#
# ```json
# [
# { "id" => "jkeiser-chef", 'username' => 'jkeiser' },
# { "id" => "cdoherty-chef", 'username' => 'cdoherty' }
# ]
# ```
#
# To translate between the two, we need to intercept requests to `users`
# like so:
#
# - `list(association_requests)` -> `get(/invitations.json)`
# - `get(association_requests/NAME)` -> `get(/invitations.json)`, see if it's in there
# - `create(association_requests/NAME)` -> `get(/invitations.json)`, add name, `set(/invitations.json)`
# - `delete(association_requests/NAME)` -> `get(/invitations.json)`, remove name, `set(/invitations.json)`

# And that will return 404 if it doesn't exist.
#
# ChefFS objects do not go to the network until you ask them for data.
# This means you can construct a /data/x/y ChefFS entry early.
#
# Alternative:
# chef_fs.child('data') could have done a GET /data preemptively,
# allowing it to know whether child('x') was valid (GET /data gives you
# a list of data bags). Then child('x') could have done a GET /data/x,
# allowing it to know whether child('y') (the item) existed. Finally,
# we would do the GET /data/x/y to read the contents. Three network
# requests instead of 1.
