[Kimchi-devel] Locking for multi-user env?

[Aline Manera]

Hi,

Kimchi uses a lock to do operations in the virtual machines.
But I think you want a generic solution for any Resource or Collection, 
if so, there is no built in support for it yet.

I don't see any reason to have a lock on a Collection as only GET and 
POST methods are allowed in it.
And the POST action is only to create a new Resource in the given 
Collection.

About your solution, I don't think we need a file. We can use 
threading.Lock() to do that.

Regards,
Aline Manera
