| 15:59 | Basic UPDATE functionality working for VIRTUAL columns. (check-in: c21959d4eb user: drh tags: generated-columns) | |
| 15:41 | Avoid an infinite loop in fts3/4 incremental-merge in the case where the lowest level in the database contains segments but no data (because there is a delete-marker for each valid entry). Fix for [bf1aab89]. (check-in: 35beaee059 user: dan tags: trunk) | |
| 14:21 | Bug fixes so that "make test" once against runs with no errors. (check-in: 7bfe0f679d user: drh tags: generated-columns) | |
| 13:15 | Fix the table_info and table_xinfo pragmas so that they work with virtual columns. Table_info omits virtual columns. Table_xinfo gives them a "hidden" flag of 2, and 3 for STORED columns. (check-in: 069351b85f user: drh tags: generated-columns) | |

| 12:18 | Initial experimental code for generated column support. Non-functional. (check-in: 11d472c1df user: drh tags: generated-columns) | |

| 18:55 | Update the zipfile extension to use deflateBound(), instead of compressBound(), to learn the maximum possible size of a deflate()d buffer. (check-in: f5ee30426e user: dan tags: trunk) | |
| 17:14 | Futher improvements to LEFT JOIN strength reduction. (check-in: 8a39167bd2 user: drh tags: trunk) | |
| 16:01 | Improvements to the LEFT JOIN strength reduction optimization. (check-in: 548082dfab user: drh tags: trunk) | |
| 15:33 | Ensure fts3/4 prefix indexes are flushed to disk before an 'optimize' command. Fix for [745f1abc]. (check-in: 4ed905b188 user: dan tags: trunk) | |
| 14:27 | Fix the fts3/4 integrity-check command so that it works with "ORDER=DESC" tables. Fix for [8a6fa2bb]. (check-in: 5863546df9 user: dan tags: trunk) | |
| 14:25 | Increase the version number to 3.31.0 for the next release cycle. (check-in: ffd4c30620 user: drh tags: trunk) | |

| 17:09 | Prevent SQLite from assuming that if ((? IS NOT NULL) IS NOT NULL) is true, ? may not be NULL. Fix for [c31034044bb72c89]. (check-in: 7833feecfe user: dan tags: trunk) | |
| 16:41 | Fix a problem in the fts3 integrity-check routine causing it to report as corrupt tables that contain values with embedded 0x00 bytes. Ticket [278ac142625e3dcd] (check-in: 629e20c988 user: dan tags: trunk) | |
| 15:17 | Be sure to rewrite column references inside FILTER clauses and window frame definitions when flattening queries. Fix for [1079ad19]. (check-in: ccba7202b6 user: dan tags: trunk) | |

| 21:14 | Avoid assuming that an expression that contains the sub-expression (? IS FALSE) or (? IS TRUE) may only be true if ? is non-null. Fix for [a976c487]. (check-in: eb7ed90b8a user: dan tags: trunk) | |
| 18:36 | Do not allow users to effectively disable fts5 crisismerge operations by setting the crisismerge threshold to higher than the maximum allowable segment b-trees on a single level. Fix for [d392017c]. (check-in: 86e4972092 user: dan tags: trunk) | |

| 17:06 | An alternative, experimental lookaside memory allocator that uses two different slot sizes. (check-in: 5ba8cee8f7 user: sperry tags: 2-size-lookaside) | |
| 15:37 | An improved fix for the dbsqlfuzz-discovered ALWAYS() failure following OOM in sqlite3ExprCollSeq(). This time with a test case (engineered by Dan). (check-in: 907f7965b3 user: drh tags: trunk) | |
| 15:26 | Disallow fts5 page sizes greater than 65536 bytes - as there are 16-bit offsets used in the page header. Fix for [81a7f7b9]. (check-in: 75775c5ab4 user: dan tags: trunk) | |
| 15:08 | Remove the "fastfuzztest" makefile target. Use only "fuzztest". (check-in: e17571c789 user: drh tags: trunk) | |
| 15:03 | New test cases added to test/fuzzdata8.db. (check-in: b68d21e93a user: drh tags: trunk) | |

| 13:34 | Fix problems with using the fts5 'rebuild' command inside a transaction that contains other updates of the same table. Fix for [e258f008]. (check-in: 238e083571 user: dan tags: trunk) | |
|

| ||
| 20:36 | Disallow page-sizes smaller than 32 bytes in fts5. Also ensure the fts5 integrity-check works even when "PRAGMA reverse_unordered_selects" is true. Fix for [265e935b26]. (check-in: 8ab0aebdb3 user: dan tags: trunk) | |
| 20:33 | Omit a pointless memory allocation in vdbeSorterSort(). (check-in: 5d76dbc5b0 user: drh tags: trunk) | |
| 18:43 | Fix a problem with running ALTER TABLE ADD COLUMN statements within a transaction that writes to one or more virtual tables. Fix for [8fe768e9]. (check-in: 31e85fbbc4 user: dan tags: trunk) | |
| 13:46 | Add a test case for the assert() fix in the previous commit. (check-in: 32fba11ab7 user: dan tags: trunk) | |
| 13:26 | Fix a faulty assert() statement in the sqlite3VdbeMemExpandBlob() routine. (check-in: 69a26eade2 user: drh tags: trunk) | |
| 01:05 | Fix the OP_SeekRowid opcode so that it works correctly with a Real argument without damaging the value in the register that is the argument. Ticket [b2d4edaffdc156cc]. Test cases in TH3. (check-in: 3cde82c86b user: drh tags: trunk) | |

| 19:53 | Omit the check for conflicting shared-cache locks in sqlite3Prepare() if the database connection uses no shared cache. We might be able to go back and remove this code completely, due to the newer Schema.iGeneration logic, but that will take more analysis. This check-in gives the speed benefit but not the reduction in code size. (check-in: 0b73a09270 user: drh tags: trunk) | |
| 19:24 | Optimization to sqlite3VtabUnlockList() for the common case when there is no work to do. (check-in: fc8d45086d user: drh tags: trunk) | |
| 18:33 | Call sqlite3Prepare() directly, rather than going through sqlite3_prepare(), when processing the sqlite_master.sql column for a schema. (check-in: cc49380ea7 user: drh tags: trunk) | |
| 15:28 | Reorder two comparisons for a small performance gain in OP_Transaction. (check-in: d7667f6560 user: drh tags: trunk) | |
| 14:39 | Performance optimization to the lookaside-memory disabling mechanism. (check-in: 17ce1c49cb user: drh tags: trunk) | |
