| ||
| 21:58 | Experimental support for new sqlite3_bind_blob() and sqlite3_bind_text() interfaces that take an extra void* argument that is passed into the destructor in front of the object that is to be destroyed. (Leaf check-in: 33a1924ebb user: drh tags: custom-destructors) | |
| 20:28 | Add a missing OP_ColumnsUsed opcode to code for expressions like "? IN (SELECT ...)" in cases where expression can use an index that may contain NULL values. (Backported fix from version 3.14.0). (Leaf check-in: 11368e673c user: drh tags: branch-3.8.9) | |

| 16:00 | Avoid a buffer overread in ptrmapPutOvflPtr() that can occurs in a corrupt database file that has large entries and uses autovacuum. (check-in: f8b781cf41 user: drh tags: trunk) | |

| 13:35 | Expand the size of the temporary page used during btree rebalancing by a few bytes, to avoid problems with small buffer overreads that can occur on corrupted database files. (check-in: 32754ca6f8 user: drh tags: trunk) | |
| 13:18 | When saving the position of a cursor at the b-tree layer, allocate a few extra bytes at the end of the buffer used to save the key. Otherwise, if the key is corrupt, the code that restores the cursor position may overread the buffer by a little. (check-in: 160b1e31c0 user: dan tags: trunk) | |
| 11:16 | Fix a problem with bytecode generation when a query involves two or more indexes on expressions connected by OR. Ticket [d96eba87698a428c1ddd0790ea04] (check-in: 7e4ed8b5c2 user: drh tags: trunk) | |

(check-in: cc42dd1510 user: drh tags: trunk) | |
| 03:14 | Detect when an attempt is made to write to a pointer map page that is also being used as a btree page and report corruption. (Closed-Leaf check-in: 3036fd71ac user: drh tags: fuzzcheck-fix) | |
| 02:29 | Fix a bug in the custom in-memory VFS used by fuzzcheck. This bug masks other bugs that should have caused some existing fuzzdata7.db entries to fail, and so this fix is initially on a branch until those other bugs can be repaired. (check-in: e0994e9995 user: drh tags: fuzzcheck-fix) | |

| 21:11 | Add extra tests for database corruption inside the defragmentPage() routine, as dbfuzz2 has found ways for corruption to leak into that point. Add test cases in fuzzdata7.db. (check-in: 997b65117f user: drh tags: trunk) | |
| 21:05 | Fix a problem in sqlite3BtreeDelete() in which deleting an entry from a corrupt database can leave a btree page with zero cells. (check-in: 682053d1e6 user: drh tags: trunk) | |
| 20:49 | Add the "decode_hexdb" TCL command to testfixture. Add the dbfuzz001.test module to demonstration how to use decode_hexdb to deserialize a dbtotxt database description for use in a corruption test. (check-in: 1f583c53f3 user: drh tags: trunk) | |
| 18:59 | Fix the CLI to keep proper track of input line numbers for use in error messages, even after processing in-line hex database inputs using ".open --hexdb". (check-in: 7ffa985816 user: drh tags: trunk) | |
| 18:30 | Fix the CLI so that the ".open --hexdb" command works even if it is contained in a subscript that is read using ".read". (check-in: 67a87399b8 user: drh tags: trunk) | |
| 16:26 | Add tests cases for recovery in wal2 mode. (check-in: 34f56f8a42 user: dan tags: wal2) | |

| 15:06 | Add the "dbtotxt" utility program and the ability to read "dbtotxt" output as a deserialized input database in the CLI, using the --hexdb option to the ".open" command. (check-in: e3bf1d3ea5 user: drh tags: trunk) | |
| 12:37 | Include OPTS in the build of dbfuzz2. (check-in: eac9c0c496 user: drh tags: trunk) | |

| 03:36 | New database corruption test cases discovered by dbfuzz2. The new cases have been added to test/fuzzdata7.db, but have not yet all been fixed, so tests will not currently pass. (check-in: b4210d320c user: drh tags: dbfuzz2-cases) | |

| 21:34 | Fix another problem found by Matthew Denton's new fuzzer. (check-in: 2b690dbdff user: drh tags: trunk) | |
| 20:39 | Add new test file wal2big.test. (check-in: e3e50bcdab user: dan tags: wal2) | |
| 20:11 | Remove an ALWAYS() from a branch that is not always taken. The test case found by OSSFuzz has been added to TH3. (check-in: 5c7dab8553 user: drh tags: trunk) | |
| 19:04 | Add tests to ensure that each of the 4 wal read-locks does what it is supposed to. (check-in: 4d5779f31d user: dan tags: wal2) | |

| 11:54 | Fix a problem with using "<db>-vacuum" (the default) as the state database when resuming an RBU vacuum. (check-in: 6b7567fc0c user: drh tags: branch-3.26) | |
| 11:50 | Do not use a partial index as a table scan in an IN operator. Fix for ticket [1d958d90596593a77420e59]. (check-in: c1c735a8c6 user: drh tags: branch-3.26) | |

| 13:44 | Merge latest trunk changes into this branch. (check-in: d8dd98a39e user: dan tags: wal2) | |

| 20:01 | Further refinements to the sqlite3_normalized_sql() interface. TH3 now gives 100% MC/DC on that interface. (check-in: c96bf6cca2 user: drh tags: trunk) | |
| 18:15 | Refactor the sqlite3_normalized_sql() implementation. (check-in: 06e955e5d2 user: drh tags: trunk) | |
| 16:53 | Merge latest mutexfree-shmlock changes into this branch. (Leaf check-in: 186b376ec3 user: dan tags: begin-concurrent-pnu-mutexfree-shmlock) | |

| 20:26 | Remove a line of code from VACUUM that is no longer needed, due to the change that allows ATTACH to run within a transaction. (check-in: a92c398fc5 user: drh tags: trunk) | |

2018-12-06

| 22:12 | Performance improvement: Avoid using sqlite3WalkerSelectExpr() and sqlite3WalkerSelectFrom() twice, so that the compiler will in-line their implementation. (Closed-Leaf check-in: 2b9258b8b0 user: drh tags: ticket-f09fcd17810f) | |

| 19:56 | New test case that still hits an assertion fault, just to prove that the previous checkin merely made the problem more obscure and did not completely fix it. (check-in: a9a3b53264 user: drh tags: ticket-f09fcd17810f) | |
| 19:15 | Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions.
