Kyle Kelley commented on LIBCLOUD-275:
--------------------------------------
All good.
At least for OpenStack, you can only copy an object within the same region
currently.
I'd be tempted to start with `ex_copy_object`, but would rather have it in the
base API (since S3, Azure Blobs, and Swift all support it in *some* way).

> Key: LIBCLOUD-275
> URL: https://issues.apache.org/jira/browse/LIBCLOUD-275
> Project: Libcloud
> Issue Type: New Feature
> Components: Storage
> Reporter: Mahendra M
> Assignee: Mahendra M
> Priority: Minor

> While working with libcloud, I thought it will be good to have some utility
> APIs to containers, which will help in easier use. Some APIs will have a base
> class implementation, which can be easily over-written in each driver based
> on the storage provider.
> Some APIs that I have in mind are:
> 1. container.copy_object(obj, target_container)
> Copies an object from one container to another. Base class implementation can
> be
>
> target_container.upload_object_via_stream(container.download_object_as_stream(obj),
> obj.name)
> In each driver, this can be over-written to use specific methods to do this
> (AWS, Azure etc. provide APIs for doing this).
> 2. container.move_object(obj, target_container)
> Base class implementation can be:
> container.copy_object(obj, target_container)
> obj.delete()
> Again, driver specific extensions can be done.
> 3. container.sync_to_local(local_path, only_missing=True, only_newer=False)
> 4. container.sync_from_local(local_path, followlinks=False, prefix='',
> only_missing=True, only_newer=False)
> The above two functions are good for syncing local folder repos with cloud.
> The functions are ridiculously easy to implement and will provide good
> mechanism for sync. (For eg: syncing a folder which contains 500 HLS chunks
> of a video)
> The parameters used are:
> * only_missing - sync only files that missing in the target (container or
> folder)
> * only_newer - sync only files that have last-modified (or m_time) more than
> the target
> * prefix - A prefix to be prefixed to each object name while syncing from a
> local folder.
> I am just opening a ticket so that we can discuss this and finalize it. Once
> everyone agree, I can submit/check-in a patch
