68 # 1. A wal mode db is opened and written. Then sqlite3_close_v2() used
69 # to close the db handle while there is still an unfinalized
70 # statement (so the db handle stays open).
72 # 2. The db, wal and *-shm files are deleted from the file system.
74 # 3. Another connection creates a new wal mode db at the same file-system
75 # location as the previous one.
77 # 4. The statement left unfinalized in (1) is finalized.
79 # The test is to ensure that the connection left open in step (1) does
80 # not try to delete the wal file from the file-system as part of step
86 # Open a connection on a wal database. Write to it a bit. Then prepare
87 # a statement and call sqlite3_close_v2() (so that the statement handle
88 # holds the db connection open).
