# Test an unusual scenario:

|
#
|
|
# 1. A wal mode db is opened and written. Then sqlite3_close_v2() used
|
|
# to close the db handle while there is still an unfinalized
|
|
# statement (so the db handle stays open).
|
|
#
|
|
# 2. The db, wal and *-shm files are deleted from the file system.
|
|
#
|
|
# 3. Another connection creates a new wal mode db at the same file-system
|
|
# location as the previous one.
|
|
#
|
|
# 4. The statement left unfinalized in (1) is finalized.
|
|
#
|
|
# The test is to ensure that the connection left open in step (1) does
|
|
# not try to delete the wal file from the file-system as part of step
|
|
# 4.
