| 15:11 | Remove the malloc2.test script since it was designed for use in versions of SQLite that predate SQLite's ability to recover from out-of-memory errors automatically. Removing this script causes no reduction in test coverage and removes potential problems reported by ticket #3213. (CVS 5409) check-in: 5bfc9625 user: drh tags: trunk | |
