| 01:01 | Prevent winOpenSharedMemory from masking the real return code from its call to winOpen. Also, add asserts to check the double-zero termination of database file names. check-in: 93a65776 user: mistachkin tags: trunk | |

| 23:18 | Only require double-zero terminators on database filenames, not any every files supplied to the xOpen method. This backs out [2544f233f1]. Also refactor the fillInUnixFile() routine in os_unix.c to reduce the number of parameters. check-in: cb774b26 user: drh tags: trunk | |
