+# This test makes sure the database file is truncated back to the correct
+# length on a rollback.
+#
+# After some preliminary setup, a transaction is start at NOTE (1).
+# The create table on the following line allocates an additional page
+# at the end of the database file.  But that page is not written because
+# the database still has a RESERVED lock, not an EXCLUSIVE lock.  The
+# new page is held in memory and the size of the file is unchanged.
+# The insert at NOTE (2) begins adding additional pages.  Then it hits
+# a constraint error and aborts.  The abort causes sqlite3OsTruncate()
+# to be called to restore the file to the same length as it was after
+# the create table.  But the create table results had not yet been
+# written so the file is actually lengthened by this truncate.  Finally,
+# the rollback at NOTE (3) is called to undo all the changes since the
+# begin.  This rollback should truncate the database again.
+# 
+# This test was added because the second truncate at NOTE (3) was not
+# occurring on early versions of SQLite 3.0.
