| 19:21 | Update the error message on one of the corruption tests to account for the fact that we are finding the corruption sooner. (CVS 6726) check-in: ba9848e7 user: drh tags: trunk | |
| 16:08 | Fix an error in the malloc.test test script causing a small buffer overread. (CVS 6725) check-in: 4d129bee user: danielk1977 tags: trunk | |
| 15:17 | Make sure the result of sqlite3VdbeGetOp() is not used as an array following an OOM error, since after (6691) it might be a single-entry dummy opcode. (CVS 6724) check-in: 127b1398 user: drh tags: trunk | |
