+ superuser {HA1}ec018ffe72b8e75bb4d508ed5b6d079c read,write

+When using the RAPI, username and password can be sent to the server
+by using the standard HTTP basic access authentication. This means that
+for accessing the protected URL ``https://cluster.example.com/resource``,
+the address ``https://username:password@cluster.example.com/resource`` should
+be used instead.
+Alternatively, the appropriate parameter of your HTTP client
+(such as ``-u`` for ``curl``) can be used.

+
+
+A note on JSON as used by RAPI
+++++++++++++++++++++++++++++++
+
+JSON_ as used by Ganeti RAPI does not conform to the specification in
+:rfc:`4627`. Section 2 defines a JSON text to be either an object
+(``{"key": "value", …}``) or an array (``[1, 2, 3, …]``). In violation
+of this RAPI uses plain strings (``"master-candidate"``, ``"1234"``) for
+some requests or responses. Changing this now would likely break
+existing clients and cause a lot of trouble.
+
+.. highlight:: ruby
+
+Unlike Python's `JSON encoder and decoder
+<http://docs.python.org/library/json.html>`_, other programming
+languages or libraries may only provide a strict implementation, not
+allowing plain values. For those, responses can usually be wrapped in an
+array whose first element is then used, e.g. the response ``"1234"``
+becomes ``["1234"]``. This works equally well for more complex values.
+Example in Ruby::
+
+ require "json"
+
+ # Insert code to get response here
+ response = "\"1234\""
+
+ decoded = JSON.parse("[#{response}]").first
+
+Short of modifying the encoder to allow encoding to a less strict
+format, requests will have to be formatted by hand. Newer RAPI requests
+already use a dictionary as their input data and shouldn't cause any
+problems.
PUT or POST?
------------
-According to RFC2616 the main difference between PUT and POST is that
-POST can create new resources but PUT can only create the resource the
-URI was pointing to on the PUT request.
+According to :rfc:`2616` the main difference between PUT and POST is
+that POST can create new resources but PUT can only create the resource
+the URI was pointing to on the PUT request.
Unfortunately, due to historic reasons, the Ganeti RAPI library is not
consistent with this usage, so just use the methods as documented below
Force operation to continue even if it will cause the cluster to become
inconsistent (e.g. because there are not enough master candidates).

+:pyeval:`errors.ECODE_RESOLVER`
Resolver errors. This usually means that a name doesn't exist in DNS,
so if it's a case of slow DNS propagation the operation can be retried
later.
-``insufficient_resources``
+:pyeval:`errors.ECODE_NORES`
Not enough resources (iallocator failure, disk space, memory,
etc.). If the resources on the cluster increase, the operation might
succeed.
-``wrong_input``
+:pyeval:`errors.ECODE_TEMP_NORES`
+ Simliar to :pyeval:`errors.ECODE_NORES`, but indicating the operation
+ should be attempted again after some time.
+
+:pyeval:`errors.ECODE_INVAL`
Wrong arguments (at syntax level). The operation will not ever be
accepted unless the arguments change.
-``wrong_state``
+:pyeval:`errors.ECODE_STATE`
Wrong entity state. For example, live migration has been requested for
a down instance, or instance creation on an offline node. The
operation can be retried once the resource has changed state.
-``unknown_entity``
+:pyeval:`errors.ECODE_NOENT`
Entity not found. For example, information has been requested for an
unknown instance.
-``already_exists``
+:pyeval:`errors.ECODE_EXISTS`
Entity already exists. For example, instance creation has been
requested for an already-existing instance.
-``resource_not_unique``
+:pyeval:`errors.ECODE_NOTUNIQUE`
Resource not unique (e.g. MAC or IP duplication).
-``internal_error``
+:pyeval:`errors.ECODE_FAULT`
Internal cluster error. For example, a node is unreachable but not set
offline, or the ganeti node daemons are not working, etc. A
``gnt-cluster verify`` should be run.
-``environment_error``
+:pyeval:`errors.ECODE_ENVIRON`
