File Versions on the Client: Use the Server API

[dragotin]

owncloud/core#10571 talks about an server API that provides information about the previous versions of a file.

The client should provide a client native dialog that shows the previous versions and allows the user to revert the file back to one of the previous verisons.

The versions dialog

• should be invoked by a context menu entry in the file manager
• should show a list of available previous versions
• should show a thumbnail with the previous versions
• allow the user to revert to a previous one and manage the sync down of the file.

@MTRichards @cmonteroluque something to address with server version 9.1?

[MTRichards]

Very similar to something I have been looking at - and that was requested for the future. The idea that, on the desktop, I could right click on a file and get a previous version list, and roll back to that version from the desktop.

It is not common as an ask, but I do think NetAPP, for example, has a feature like this on the network drive mounts for desktop users. Something to consider longer term.

NetApp seems to implement a Volume Copy Service Provider: https://msdn.microsoft.com/en-us/library/windows/desktop/aa381601(v=vs.85).aspx

The result is a native integration with the windows file property dialog:

@dragotin I have not looked at the Windows Interfaces. Do you think this is possible?

@butonic everything is possible.

[butonic]

@dragotin good, how much effort do you think it is?

[dragotin]

lol @butonic lets talk once we have a server api.

[dragotin]

@butonic ah, you probably mean how much effort it is to add that tab to the properties dialog?! No idea, honestly, needs investigation. But stuff like that is usually doable as you find examples in the net. An issue is to build that in our infra, as we use cross compiling, and these things often require native building.

@MTRichards schedule for 9.2?

[MTRichards]

Love the idea, we need to add to the versions API to make it happen, then possible. Not going to make 9.1 right now, that is largely set with L1 and L2 and this didn't make it high enough on the priority list.

We have an (undocumented) API for this nowadays: owncloud/core#29257.

it's documented here now: https://doc.owncloud.com/server/10.0/developer_manual/webdav_api/files_versions.html
