| -# 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.
