24# To roll back a hot-journal file, the application needs read and write
25# permission on the journal file in question. The following tests test
26# the outcome of trying to rollback a hot-journal file when this is not
27# the case.
28#
29#   tkt3457-1.2: Application has neither read, nor write permission on
30#                the hot-journal file. Result: SQLITE_CANTOPEN.
31#
32#   tkt3457-1.3: Application has write but not read permission on
33#                the hot-journal file. Result: SQLITE_CANTOPEN.
34#
35#   tkt3457-1.4: Application has read but not write permission on
36#                the hot-journal file. Result: SQLITE_CANTOPEN.
37#
38#   tkt3457-1.5: Application has read/write permission on the hot-journal
39#                file. Result: SQLITE_OK.
