-# This file implements regression tests for SQLite library.
-#
-# This file implements tests to verify that ticket #2409 has been
-# fixed. More specifically, they verify that if SQLite cannot
-# obtain an EXCLUSIVE lock while trying to spill the cache during
-# any statement other than a COMMIT, an I/O error is returned instead
-# of SQLITE_BUSY.

-# Test Outline:
-#
-#   tkt-2409-1.*: Cause a cache-spill during an INSERT that is within
-#       a db transaction but does not start a statement transaction.
-#       Verify that the transaction is automatically rolled back
-#       and SQLITE_IOERR_BLOCKED is returned
-#
-#       UPDATE: As of the pcache modifications, failing to upgrade to
-#       an exclusive lock when attempting a cache-spill is no longer an
-#       error. The pcache module allocates more space and keeps working
-#       in memory if this occurs.
-#
-#   tkt-2409-2.*: Cause a cache-spill while updating the change-counter
-#       during a database COMMIT. Verify that the transaction is not
-#       rolled back and SQLITE_BUSY is returned.
-#
-#   tkt-2409-3.*: Similar to 2409-1.*, but using many INSERT statements
-#       within a transaction instead of just one.
-#
-#       UPDATE: Again, pcache now just keeps working in main memory.
-#
-#   tkt-2409-4.*: Similar to 2409-1.*, but rig it so that the
-#       INSERT statement starts a statement transaction. Verify that
-#       SQLITE_BUSY is returned and the transaction is not rolled back.
-#
-#       UPDATE: This time, SQLITE_BUSY is not returned. pcache just uses
-#       more malloc()'d memory.
