Refactored object{,_container} modules breaking backward compatibility

Browse Source 
Previously both modules object and object_container had huge overlaps in
functionality. Both allowed to create and delete containers. One would
not have to pass a object to the object module at all and could use it
to manage containers only. Now the object module has been changed to
manage an object in a container only while the object_container module
is responsible for managing Swift containers only.

With object module it is now also possible to pass data instead of a
filename via module options. The container_access functionality has been
dropped from object module. It has been moved and extended as read_ACL
and write_ACL options in object_container module.

With object_container module it is now also possible to manage the
container access with read_ACL and write_ACL options. Those mirror
earlier container_access option of the object module which has been
removed.

- This container will not be created if it does not exist already.
required: true

- The content to upload to the object.

EXAMPLES = '''
- name: "Create a object named 'fstab' in the 'config' container"
RETURN = r'''
object:
description: Dictionary describing the object.
returned: On success when I(state) is C(present).
type: dict
contains:
accept_ranges:
description: The type of ranges that the object accepts.
type: str
access_control_allow_origin:
description: CORS for RAX (deviating from standard)
type: str
content_disposition:
description: If set, specifies the override behavior for the browser.
For example, this header might specify that the browser use
a download program to save this file rather than show the
file, which is the default. If not set, this header is not
returned by this operation.
type: str
content_encoding:
description: If set, the value of the Content-Encoding metadata.
If not set, this header is not returned by this operation.
type: str
content_length:
description: HEAD operations do not return content. However, in this
operation the value in the Content-Length header is not the
size of the response body. Instead it contains the size of
the object, in bytes.
type: str
content_type:
description: The MIME type of the object.
type: int
copy_from:
description: If set, this is the name of an object used to create the new
object by copying the X-Copy-From object. The value is in
form {container}/{object}. You must UTF-8-encode and then
URL-encode the names of the container and object before you
include them in the header. Using PUT with X-Copy-From has
the same effect as using the COPY operation to copy an
object.
type: str
delete_after:
description: Specifies the number of seconds after which the object is
removed. Internally, the Object Storage system stores this
value in the X-Delete-At metadata item.
type: int
delete_at:
description: If set, the time when the object will be deleted by the
system in the format of a UNIX Epoch timestamp. If not set,
this header is not returned by this operation.
type: str
etag:
description: For objects smaller than 5 GB, this value is the MD5
checksum of the object content. The value is not quoted.
For manifest objects, this value is the MD5 checksum of the
concatenated string of MD5 checksums and ETags for each of
the segments in the manifest, and not the MD5 checksum of
the content that was downloaded. Also the value is enclosed
in double-quote characters.
You are strongly recommended to compute the MD5 checksum of
the response body as it is received and compare this value
with the one in the ETag header. If they differ, the content
was corrupted, so retry the operation.
type: str
expires_at:
description: Used with temporary URLs to specify the expiry time of the
signature. For more information about temporary URLs, see
OpenStack Object Storage API v1 Reference.
type: str
id:
description: ID of the object. Equal to C(name).
type: str
if_match:
description: See U(http://www.ietf.org/rfc/rfc2616.txt).
type: list
if_modified_since:
description: See U(http://www.ietf.org/rfc/rfc2616.txt).
type: str
if_none_match:
description: "In combination with C(Expect: 100-Continue), specify an
C(If-None-Match: *) header to query whether the server
already has a copy of the object before any data is sent."
type: list
if_unmodified_since:
description: See U(http://www.ietf.org/rfc/rfc2616.txt).
type: str
is_content_type_detected:
description: If set to true, Object Storage guesses the content type
based on the file extension and ignores the value sent in
the Content-Type header, if present.
type: bool
is_newest:
description: If set to True, Object Storage queries all replicas to
return the most recent one. If you omit this header, Object
Storage responds faster after it finds one valid replica.
Because setting this header to True is more expensive for
the back end, use it only when it is absolutely needed.
type: bool
is_static_large_object:
description: Set to True if this object is a static large object manifest
object.
type: bool
last_modified_at:
description: The date and time that the object was created or the last
time that the metadata was changed.
type: str
manifest:
description: If present, this is a dynamic large object manifest object.
The value is the container and object name prefix of the
segment objects in the form container/prefix.
type: str
multipart_manifest:
description: If you include the multipart-manifest=get query parameter
and the object is a large object, the object contents are
not returned. Instead, the manifest is returned in the
X-Object-Manifest response header for dynamic large objects
or in the response body for static large objects.
type: str
name:
description: Name of the object.
returned: success
type: str
object_manifest:
description: If set, to this is a dynamic large object manifest object.
The value is the container and object name prefix of the
segment objects in the form container/prefix.
type: str
range:
description: TODO.
type: dict
signature:
description: Used with temporary URLs to sign the request. For more
information about temporary URLs, see OpenStack Object
Storage API v1 Reference.
type: str
symlink_target:
description: If present, this is a symlink object. The value is the
relative path of the target object in the format
<container>/<object>.
type: str
symlink_target_account:
description: If present, and X-Symlink-Target is present, then this is a
cross-account symlink to an object in the account specified
in the value.
type: str
timestamp:
description: The timestamp of the transaction.
type: str
transfer_encoding:
description: Set to chunked to enable chunked transfer encoding. If used,
do not set the Content-Length header to a non-zero value.
type: str
