# These are 'warm-body' tests used while developing the WAL code. They |
# serve to prove that a few really simple cases work: |
# |
# wal-1.*: Read and write the database. |
# wal-2.*: Test MVCC with one reader, one writer. |
# wal-3.*: Test transaction rollback. |
# wal-4.*: Test savepoint/statement rollback. |
# wal-5.*: Test the temp database. |
# wal-6.*: Test creating databases with different page sizes. |

# is large enough for a log file that contains approximately 13100 frames. |
# So the following tests create logs containing at least this many frames. |
# |
# wal-13.1.*: This test case creates a very large log file within the |
# file-system (around 200MB). The log file does not contain |
# any valid frames. Test that the database file can still be |
# opened and queried, and that the invalid log file causes no |
# problems. |
# |
# wal-13.2.*: Test that a process may create a large log file and query |
# the database (including the log file that it itself created). |
# |
# wal-13.3.*: Test that if a very large log file is created, and then a |
# second connection is opened on the database file, it is possible |
# to query the database (and the very large log) using the |
# second connection. |
# |
# wal-13.4.*: Same test as wal-13.3.*. Except in this case the second |
# connection is opened by an external process. |

# The following test - wal-19.* - fixes a bug that was present during |
# development. |
# |
# When a database connection in WAL mode is closed, it attempts an |
# EXCLUSIVE lock on the database file. If the lock is obtained, the |
# connection knows that it is the last connection to disconnect from |
# the database, so it runs a checkpoint operation. The bug was that |
# the connection was not updating its private copy of the wal-index |
# header before doing so, meaning that it could checkpoint an old |
# snapshot. |

# This test - wal-20.* - uses two connections. One in this process and |
# the other in an external process. The procedure is: |
# |
# 1. Using connection 1, create the database schema. |
# |
# 2. Using connection 2 (in an external process), add so much |
# data to the database without checkpointing that a wal-index |
# larger than 64KB is required. |
# |
# 3. Using connection 1, checkpoint the database. Make sure all |
# the data is present and the database is not corrupt. |
# |
# At one point, SQLite was failing to grow the mapping of the wal-index |
# file in step 3 and the checkpoint was corrupting the database file. |
