I have thought about that. But it will be a new feature instead of a bug fix and my intention here was to fix the test case is failing.
Sorry, I was thinking about the UI instead the backend when I replied to you.
The delete operation will have a confirmation on UI as we did for VM, for example, but no additional parameter is needed on backend to confirm this action.
So when we will have the UI to manage storage volume, a confirmation box will be shown to user but once confirmed a DELETE request is sent without additional parameter.
Does that make sense?
I think that Paulo is saying to create a way to let user choose if he wants to delete or not the image file from the system. Like:
def delete(self, pool, name, wipe=True):
If wipe is False, then you should keep the file. Thinking on backend perspective (API) it is good option.
Rodrigo
Yeah, Rodrigo got the main idea, but my idea is to the opposite - if True then remove the file.
However, if the idea is really remove you can use what Rodrigo said. Hmm... I understand it is a nice to have feature, but Kimchi must have a default behavior. And the default behavior IMO should be to delete the file (the same approach we have when deleting a virtual machine and, in which, this delete parameter also makes sense if you think about it).
Thinking about the Kimchi user (who does not have virtualization background), when deleting a storage volume it is supposed that the storage volume will go away. Why should he/she answer a question "Do you want to remove the file associated to this storage volume?" ? It may confuse the user IMO.
So, I keep thinking when deleting the storage volume, the default behavior should be to remove the file. (and that would be the behavior used on UI).
But I agree in having this delete parameter as a nice to have feature for the next release (as we are on code freeze for 2.1 release)
Ok, so let's add this as future feature.
I will open 2 issues (one for storage volume and other to guest) to cover it.
