hmmm... when a doc is renamed, if we restore a version before the rename, shouldn't we get back the old, not renamed, document?
Thought about it too, and I think that the answer is no. The rename is not a version-able change. Looking in the history, there's no indication that the document has been renamed, or that it used to have a different name. "Rename" is a meta-change, it alters the name with which a document (seen as the information inside it) can be reached. Reverting the document refers to reverting the information. Think of the following use cases: A document is create with a typo in its name. It survives like this for a while, adding several revisions. After that, someone corrects the typo in the name by renaming the document. Then, someone sees some bad edits and wants to revert the document to its previous state. Is it OK to go back to the old, wrong document name? A document is created with a name. Not much activity in it, then someone renames the document, and it stays like this for a long time. People get accustomed to the new name and forget that it even had a different name initially. Then someone reverts to the previous version. For the public, the document disappeared, since nobody remembers the old name. Now, IF the rename did appear in the history, and the user explicitly deletes the "rename" change, I might be OK with moving back the document, but in the current situation, I think that the implemented behavior is the right one. On a sidenote, we just deprecated the setDocumentReference method, since we're not supposed to use it. Yet, I just did use it. What does this mean: - there are valid usecases for setDocumentReference, or - I should change the existing reference, like getDR().setName? -- Sergiu Dumitriu http://purl.org/net/sergiu/
