""" Setup v0 of the API server

v0_api() must be called to setup the API routes for Flask

Status Responses
----------------

Some requests only return a status/error response.

  The response will be a status response with `status` set to true, or an
  error response with it set to false and an error message included.

  Example response::

      {
        "status": true
      }

  Error response::

      {
        "errors": ["ggit-error: Failed to remove entry. File isn't in the tree - jboss.toml (-1)"]
        "status": false
      }

API Routes
----------

All of the blueprints routes support the optional `branch` argument. If it is not
used then the API will use the `master` branch for blueprints. If you want to create
a new branch use the `new` or `workspace` routes with ?branch=<branch-name> to
store the new blueprint on the new branch.

`/api/v0/blueprints/list`
^^^^^^^^^^^^^^^^^^^^^^^^^

  List the available blueprints::

      { "limit": 20,
        "offset": 0,
        "blueprints": [
          "atlas",
          "development",
          "glusterfs",
          "http-server",
          "jboss",
          "kubernetes" ],
        "total": 6 }

`/api/v0/blueprints/info/<blueprint_names>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Return the JSON representation of the blueprint. This includes 3 top level
  objects.  `changes` which lists whether or not the workspace is different from
  the most recent commit. `blueprints` which lists the JSON representation of the
  blueprint, and `errors` which will list any errors, like non-existant blueprints.

  Example::

      {
        "changes": [
          {
            "changed": false,
            "name": "glusterfs"
          }
        ],
        "errors": [],
        "blueprints": [
          {
            "description": "An example GlusterFS server with samba",
            "modules": [
              {
                "name": "glusterfs",
                "version": "3.7.*"
              },
              {
                "name": "glusterfs-cli",
                "version": "3.7.*"
              }
            ],
            "name": "glusterfs",
            "packages": [
              {
                "name": "2ping",
                "version": "3.2.1"
              },
              {
                "name": "samba",
                "version": "4.2.*"
              }
            ],
            "version": "0.0.6"
          }
        ]
      }

  Error example::

      {
        "changes": [],
        "errors": ["ggit-error: the path 'missing.toml' does not exist in the given tree (-3)"]
        "blueprints": []
      }

`/api/v0/blueprints/changes/<blueprint_names>[?offset=0&limit=20]`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Return the commits to a blueprint. By default it returns the first 20 commits, this
  can be changed by passing `offset` and/or `limit`. The response will include the
  commit hash, summary, timestamp, and optionally the revision number. The commit
  hash can be passed to `/api/v0/blueprints/diff/` to retrieve the exact changes.

  Example::

      {
        "errors": [],
        "limit": 20,
        "offset": 0,
        "blueprints": [
          {

          }
        ]
      }

POST `/api/v0/blueprints/new`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Create a new blueprint, or update an existing blueprint. This supports both JSON and TOML
  for the blueprint format. The blueprint should be in the body of the request with the
  `Content-Type` header set to either `application/json` or `text/x-toml`.

  The response will be a status response with `status` set to true, or an
  error response with it set to false and an error message included.

DELETE `/api/v0/blueprints/delete/<blueprint_name>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Delete a blueprint. The blueprint is deleted from the branch, and will no longer
  be listed by the `list` route. A blueprint can be undeleted using the `undo` route
  to revert to a previous commit.

  The response will be a status response with `status` set to true, or an
  error response with it set to false and an error message included.

POST `/api/v0/blueprints/workspace`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Write a blueprint to the temporary workspace. This works exactly the same as `new` except
  that it does not create a commit. JSON and TOML bodies are supported.

  The workspace is meant to be used as a temporary blueprint storage for clients.
  It will be read by the `info` and `diff` routes if it is different from the
  most recent commit.

  The response will be a status response with `status` set to true, or an
  error response with it set to false and an error message included.

DELETE `/api/v0/blueprints/workspace/<blueprint_name>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Remove the temporary workspace copy of a blueprint. The `info` route will now
  return the most recent commit of the blueprint. Any changes that were in the
  workspace will be lost.

  The response will be a status response with `status` set to true, or an
  error response with it set to false and an error message included.

POST `/api/v0/blueprints/undo/<blueprint_name>/<commit>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  This will revert the blueprint to a previous commit. The commit hash from the `changes`
  route can be used in this request.

  The response will be a status response with `status` set to true, or an
  error response with it set to false and an error message included.

POST `/api/v0/blueprints/tag/<blueprint_name>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Tag a blueprint as a new release. This uses git tags with a special format.
  `refs/tags/<branch>/<filename>/r<revision>`. Only the most recent blueprint commit
  can be tagged. Revisions start at 1 and increment for each new tag
  (per-blueprint). If the commit has already been tagged it will return false.

  The response will be a status response with `status` set to true, or an
  error response with it set to false and an error message included.

`/api/v0/blueprints/diff/<blueprint_name>/<from_commit>/<to_commit>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Return the differences between two commits, or the workspace. The commit hash
  from the `changes` response can be used here, or several special strings:

  - NEWEST will select the newest git commit. This works for `from_commit` or `to_commit`
  - WORKSPACE will select the workspace copy. This can only be used in `to_commit`

  eg. `/api/v0/blueprints/diff/glusterfs/NEWEST/WORKSPACE` will return the differences
  between the most recent git commit and the contents of the workspace.

  Each entry in the response's diff object contains the old blueprint value and the new one.
  If old is null and new is set, then it was added.
  If new is null and old is set, then it was removed.
  If both are set, then it was changed.

  The old/new entries will have the name of the blueprint field that was changed. This
  can be one of: Name, Description, Version, Module, or Package.
  The contents for these will be the old/new values for them.

  In the example below the version was changed and the ping package was added.

  Example::

      {
        "diff": [
          {
            "new": {
              "Version": "0.0.6"
            },
            "old": {
              "Version": "0.0.5"
            }
          },
          {
            "new": {
              "Package": {
                "name": "ping",
                "version": "3.2.1"
              }
            },
            "old": null
          }
        ]
      }

`/api/v0/blueprints/freeze/<blueprint_names>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Return a JSON representation of the blueprint with the package and module versions set
  to the exact versions chosen by depsolving the blueprint.

  Example::

      {
        "errors": [],
        "blueprints": [
          {
            "blueprint": {
              "description": "An example GlusterFS server with samba",
              "modules": [
                {
                  "name": "glusterfs",
                  "version": "3.8.4-18.4.el7.x86_64"
                },
                {
                  "name": "glusterfs-cli",
                  "version": "3.8.4-18.4.el7.x86_64"
                }
              ],
              "name": "glusterfs",
              "packages": [

                  "version": "4.6.2-8.el7.x86_64"
                }
              ],
              "version": "0.0.6"
            }
          }
        ]
      }

`/api/v0/blueprints/depsolve/<blueprint_names>`
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  Depsolve the blueprint using yum, return the blueprint used, and the NEVRAs of the packages
  chosen to satisfy the blueprint's requirements. The response will include a list of results,
  with the full dependency list in `dependencies`, the NEVRAs for the blueprint's direct modules
  and packages in `modules`, and any error will be in `errors`.

  Example::

      {
        "errors": [],
        "blueprints": [
          {
            "dependencies": [
