| 19:10 | Fix issues with ALTER TABLE and triggers containing "UPDATE...FROM" statements. (check-in: 2fba0d41b7 user: dan tags: trunk) | |
| 17:33 | Correct handling of outer joins in the FROM clause of an UPDATE statement that occurs inside of a trigger. Follow-on to [98b3816bbaf539ea]. (check-in: 664a49fa81 user: drh tags: trunk) | |
| 14:46 | Clarification of the meaning of the N parameter in sqlite3_db_name(). Documentation only. No changes to code. (check-in: f22f41d2c8 user: drh tags: trunk) | |
| 05:18 | Fixed a minor cut/paste mistake in the previous checkin. Affects only internal docs. (check-in: 37e3764839 user: stephan tags: trunk) | |
| 05:08 | Makefile.in: added explanations, intended for maintainers and hackers, of the various emcc flags used for building the wasm files. No code or build rule changes. (check-in: 1a15915909 user: stephan tags: trunk) | |

| 23:10 | Improvements to the constant-propagation optimization in order to better deal with unusual affinities. See forum post 6a06202608 for more detail. (check-in: 9be208a6d7 user: drh tags: trunk) | |
| 19:52 | Minor optimization to opcode comparison logic in the fixes to the constant-propagation optimization on this branch. (Closed-Leaf check-in: f17dec40a0 user: drh tags: constant-propagation-fix) | |
| 19:37 | Add new test file whereM.test. Containing tests for the change on this branch. (check-in: c4c76b824c user: dan tags: constant-propagation-fix) | |
| 18:51 | Avoid assuming that an expression like "x=10" in a WHERE clause implies that CASE(x AS TEXT)=='10'. (check-in: 389ec669f4 user: dan tags: constant-propagation-fix) | |
| 18:46 | Take care that the code is not generated for the same Select object more than once, as transformations that apply during the first pass might cause problems for the second pass. dbsqlfuzz 836b625cd8a41809ef80fc7ebaa6554357bcb463. (check-in: f30fb19ff7 user: drh tags: trunk) | |
| 14:32 | Update an assert() in wherecode.c that might fail following an unrelated SQL error. (check-in: 3e2c36a827 user: dan tags: trunk) | |

| 20:33 | Fix the cksumvfs extension so that it will not register itself more than once. (check-in: d5cdd57150 user: drh tags: trunk) | |
| 20:31 | Performance optimization in the transfer of error messages from statements to connections. (check-in: 0e898f4fed user: drh tags: trunk) | |
| 11:23 | Increase the version number to 3.33.0 to begin the next release cycle. (check-in: 790badb390 user: drh tags: trunk) | |
| 11:10 | Changes to sqlite3SelectNew() to work around a false-positive warning from GCC-10. The code is very slightly larger and slower as a result. (check-in: 04e1edd8e5 user: drh tags: trunk) | |
| 10:54 | Innocuous changes to help Coverity avoid false-positives. (check-in: 4ec8a5a203 user: drh tags: trunk) | |

| 20:07 | Avoid branching on an uninitalized variable when comparing SQL values with the undefined serial types 10 and 11 (which only appear in corrupt databases). (check-in: b4a45d3b78 user: dan tags: trunk) | |
| 19:08 | The "make fuzztest" target now uses fuzzcheck instead of fuzzershell. Test data is added for database fuzz testing. (check-in: 5e3e410bf4 user: drh tags: trunk) | |
| 19:01 | Merge accidental fork. (Closed-Leaf check-in: e85628e34a user: dan tags: test-using-fuzzcheck) | |

| 18:15 | The "make fuzztest" target now uses fuzzcheck instead of fuzzershell. (check-in: 4a5f6f1f01 user: drh tags: test-using-fuzzcheck) | |
| 17:57 | Enhance fuzzcheck with the ability to store descriptions in each source database and to run multiple source databases in a single invocation. (check-in: 193364c81c user: drh tags: trunk) | |
| 17:33 | Add a cast to one side of the test added by [97806a78] in order to avoid a signed/unsigned comparison warning. (check-in: 5b46d2a78a user: dan tags: trunk) | |

| 15:06 | Change the semantics of xShmGet() such that it will never increase the size of shared memory. xShmSize() must be used to grow the size of shared memory. A shared memory segment size cannot be shrunk (except by dropping it). (check-in: 72de007312 user: drh tags: trunk) | |
