This doesn't actually change much, but makes the code less surprising. Status quo ante: 1. Open a journal file 2. If newly created set header machine ID to zero 3. If existing and open for write check if machine ID in header matches local one, if not, refuse. 4. if open for writing, now refresh the machine ID from the local system Of course, step 4 is pretty much pointless for existing files, as the check in 3 made sure it is already in order or we'd refuse operating on it anyway. With this patch this is simplified to: 1. Open a journal file 2. If newly created initialized machine ID to local machine ID 3. If existing, compare machine ID in header with local one, if not matching refuse. Outcome is the same.
