| 17:18 | Within a backup operation, ensure that a read-transaction is opened on the source database before its page size is read. This ensures the page-size used to write to the backup database is the same as its actual page-size, which is important for ZipVFS databases. check-in: 7908fc60 user: dan tags: trunk | |
