Overview
| Comment: | Ensure that UTF16 strings are properly zero-terminated before returning them in an sqlite3_value_text16() request, even if the string is invalid UTF16 because it was formed from an arbitrary and/or odd-length BLOB. |

| 01:22 | Make sure the OP_Concat opcode always correctly zero-terminates a UTF16 string, even if the input strings are ill-formed. This is a followup to check-in [3a16ddf91f0c9c516a7] that fixes a case the previous check-in missed. Also add assert()s to prove correct zero termination. check-in: d612fb78 user: drh tags: trunk | |

| 01:41 | In the sqlite3_value or Mem object, make the MEM_IntReal type completely independent from MEM_Int and MEM_Real. This helps avoid problems when inserting non-float values into a "REAL" column. check-in: 5a8a23ee user: drh tags: trunk | |
