| 21:55 | Avoid creating an automatic index on a column that is known to be not very selective. (Closed-Leaf check-in: 70409763f7 user: drh tags: auto-index-improvements) | |
| 19:52 | The previous check-in was a little two aggressive about skipping the initialization of entries in the CellArray.ixNx array. Fixed here. (check-in: 1b6d1fbcde user: drh tags: trunk) | |
| 18:15 | Fix typo in comment used to generate parts of the documentation. Forum post da5a2ca4db. (check-in: 428aadf0c7 user: drh tags: trunk) | |
| 15:13 | Very small performance increase and size reduction by removing unnecessary ALWAYS() macros from the btree balance logic and replacing them with special initialization of CellArray and some assert()s. (check-in: 32b79041d9 user: drh tags: trunk) | |
| 13:41 | Doc typo fix. No code changes. (check-in: eaf07fe69f user: stephan tags: trunk) | |
| 13:24 | For compatibility with PostgreSQL, when right-hand side of the ->> operator is negative, it should index from the right side of the JSON array on the left-hand side. (check-in: 82365a45b9 user: drh tags: trunk) | |
| 11:38 | Fix a possible buffer overwrite in the ".import" command. (check-in: 55eee9f920 user: drh tags: branch-3.46) | |
| 11:35 | Fix a possible buffer overwrite in the ".import" command. forum post 0c447f0548. (check-in: 0fd958fa9b user: dan tags: trunk) | |
| 11:31 | Add new assert() statements to help out a static analyzer. Response to forum post 17fe8ac32e0de4f5. (check-in: 857f6d5309 user: drh tags: trunk) | |

| 19:34 | Add extra tests for fts5, large rowids and "ORDER BY rowid DESC". No changes to code. (check-in: b5b5eaeed3 user: dan tags: trunk) | |
| 00:03 | CLI much closer to being callable. (fewer exit() calls) ^C interrupt response improved. Sync w/trunk. Some diagnostic code removed. Some refactoring for sake of FIDDLE build. Streamline main(), by moving code to more dedicated routines and otherwise. Make -quiet more useful. (check-in: bff3a9a834 user: larrybr tags: cli_extension) | |

| 18:06 | Mark an always-true conditional as ALWAYS(). (check-in: 3492fe8a21 user: drh tags: trunk) | |
| 17:36 | Minor simplification to ALTER TABLE logic. (check-in: 01beb0365c user: drh tags: trunk) | |
| 17:13 | Corrected a broken HTML comment (was using a C-style comment closer). (check-in: db742e3e7d user: stephan tags: trunk) | |
| 15:33 | Fix another problem with ALTER TABLE and UPDATE...FROM in triggers. (check-in: 33cf12235e user: dan tags: trunk) | |
| 15:04 | Fix further issues with ALTER TABLE and triggers that contain UPDATE..FROM statements. (check-in: 53fbc269dd user: dan tags: trunk) | |
| 14:41 | Omit an unnecessary branch. (check-in: f56473f9cc user: drh tags: trunk) | |
| 03:27 | fiddle: added an option to completely wipe/reset the db. The Options area can now be toggled on/off via tapping the label at its top. Running the input SQL is now limited to the selected area if any text is currently selected, per suggestion in the forum. (check-in: d100283e37 user: stephan tags: trunk) | |

| 15:24 | The SQLITE_ENABLE_SHARED_SCHEMA compile-time option is on by default in the configure-generated makefile, permitting a complete test of this branch using "./configure && make test". (check-in: e867d22622 user: drh tags: reuse-schema) | |
| 14:09 | Improved comment on the prpagateConstants() routine. No changes to executable code. (check-in: d61a875df4 user: drh tags: trunk) | |

| 19:35 | The fuzzoomtest makefile target is no longer supported, so update releasetest.tcl accordingly. (check-in: 06959d4ada user: drh tags: trunk) | |
| 18:19 | Fix a minor and harmless memory leak in fuzzcheck. Adjust the makefiles to run fuzzcheck with --quiet on valgrind tests. (check-in: 8bfe834432 user: drh tags: trunk) | |

| 15:42 | A different approach to preventing buffer overreads when comparing a vector of values with a corrupt index record that spans at least one overflow page. (check-in: 95eaa49f4e user: drh tags: trunk) | |
| 15:10 | Disallow the use of "rowid" in CTEs - it has never worked correctly and it makes no sense, so we might as well make it an explicit error. Also: add the PRAGMA cell_size_check=ON command. (check-in: 19e2cebc12 user: drh tags: trunk) | |
| 14:21 | A different approach to preventing buffer overreads when comparing a vector of values with a corrupt index record that spans at least one overflow page. (Closed-Leaf check-in: 7e9e1b6123 user: dan tags: avoid-buffer-overread) | |
| 13:06 | CTEs have never had working rowids. So disallow the use of the "rowid" column within CTEs. (Closed-Leaf check-in: 0055df0445 user: drh tags: no-rowid-in-cte) | |
| 03:46 | Add the "PRAGMA cell_size_check=ON" command. (Closed-Leaf check-in: 2ead43f074 user: drh tags: cell-size-check-pragma) | |
