I am using sqlite3_changeset API to add undo/redo capabilities to an app. I record sqlite operations and I store all of them in a sqlite3_session object.
When I need to UNDO an operation I simply do something like: rc = sqlite3session_changeset(session, &pnChangeset, &ppChangeset); rc = sqlite3changeset_invert(pnChangeset, ppChangeset, &pnInvertedChangeset, &ppInvertedChangeset); rc = sqlite3changeset_apply (self.db, pnInvertedChangeset, ppInvertedChangeset, NULL, fConflict, NULL); The problem is that I would like to reuse the same session object to perform the REDO operation but after executing the UNDO code above, when I call: rc = sqlite3session_changeset(session, &pnChangeset, &ppChangeset); pnChangeset is always 0. Is this a bug or something not correctly documented?
