+# Test large log summaries. |
+# |
+# In this case "large" usually means a log file that requires a wal-index |
+# mapping larger than 64KB (the default initial allocation). A 64KB wal-index |
+# is large enough for a log file that contains approximately 13100 frames. |
+# So the following tests create logs containing at least this many frames. |
+# |
+# 4.1.*: 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. |
+# |
+# 4.2.*: Test that a process may create a large log file and query |
+# the database (including the log file that it itself created). |
+# |
+# 4.3.*: 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. |
+# |
+# 4.4.*: Same test as wal-13.3.*. Except in this case the second |
+# connection is opened by an external process. |
