| 131 # Test large log summaries. |
| 132 # |
| 133 # In this case "large" usually means a log file that requires a wal-index |
| 134 # mapping larger than 64KB (the default initial allocation). A 64KB wal-index |
| 135 # is large enough for a log file that contains approximately 13100 frames. |
| 136 # So the following tests create logs containing at least this many frames. |
| 137 # |
| 138 # 4.1.*: This test case creates a very large log file within the |
| 139 # file-system (around 200MB). The log file does not contain |
| 140 # any valid frames. Test that the database file can still be |
| 141 # opened and queried, and that the invalid log file causes no |
| 142 # problems. |
| 143 # |
| 144 # 4.2.*: Test that a process may create a large log file and query |
| 145 # the database (including the log file that it itself created). |
| 146 # |
| 147 # 4.3.*: Test that if a very large log file is created, and then a |
| 148 # second connection is opened on the database file, it is possible |
| 149 # to query the database (and the very large log) using the |
| 150 # second connection. |
| 151 # |
| 152 # 4.4.*: Same test as wal-13.3.*. Except in this case the second |
| 153 # connection is opened by an external process. |
