| 18:54 | Revert Lemon so that it only shows -D options that are actually used. Though the change to display the options in sorted order is retained. (check-in: e54eb217c9 user: drh tags: trunk) | |
| 18:46 | In lemon, show all the -D options in the generated header, even if none of them are used. (check-in: 2aa009c38b user: drh tags: trunk) | |
| 16:38 | Enhance lemon.c so that when it shows the compile-time options in the header comment of the generated output file, it shows all options, even those not used, and it shows them in sorted order. (check-in: eed76e6698 user: drh tags: trunk) | |
| 11:08 | Remove some extraneous flags from the fiddle-debug build. Internal doc tweaks in the main wasm makefile. (check-in: afae2c9e6f user: stephan tags: trunk) | |

| 23:27 | Avoid unnecessary NULL pointer checks on calls to sqlite3WalkExpr(). (check-in: 73d86a12fb user: drh tags: trunk) | |
| 20:54 | Small performance improvement and size reduction by recognizing that no SQL keywords have less than 2 characters. (check-in: 6b3d25b798 user: drh tags: trunk) | |
| 18:16 | Add the sqlite3_commit_status() API. For querying a connection for (a) the ranges of wal/wal2 frames written after a successful commit, and (b) the conflicting frame following a failed commit of a BEGIN CONCURRENT transaction. (check-in: 4b08d4dad6 user: dan tags: bedrock) | |
| 13:09 | Fix large integer constants so that they work on older C compilers. (check-in: 3c94f87806 user: drh tags: trunk) | |

| 16:55 | Follow-up to check-in [0057bbb508e7662b] - ensure that the database page has been initialized prior to continuing with the optimization. If the page is not initialized, that indicates that the database is corrupt. dbsqlfuzz 09ee46becd5e6d1b2a55c9f8ad767335a90aadb0. (check-in: 11162446f1 user: drh tags: trunk) | |

| 20:20 | Remove unnecessary (redundant) variable initialization from sqlite3BtreeInsert() for a small size reduction and performance increase. (check-in: 70d1836474 user: drh tags: trunk) | |
| 18:35 | The previous check-in is a significant change to btree, so go ahead and increment the version number for the next development cycle. (check-in: 2eb6697051 user: drh tags: trunk) | |
| 18:32 | Split the sqlite3BtreeMovetoUnpacked() routine into two separate routines sqlite3BtreeTableMoveto() and sqlite3BtreeIndexMoveto(), since we usually know the type of btree in advance. This results in less branching and better performance. (check-in: 3b0d34e5e5 user: drh tags: trunk) | |

| 15:35 | Reverse unintentional spacing change in the previous check-in. (check-in: c7b2ee1edb user: mistachkin tags: trunk) | |
| 15:33 | Include 'sqlite3rc.h' in the amalgamation archive targets. (check-in: 3df579ca32 user: mistachkin tags: trunk) | |
| 15:24 | Extend the refactoring into extensions. Clean up stray newlines. (check-in: 7a876209a6 user: drh tags: trunk) | |
| 13:33 | Further refactoring of the schema table name. (check-in: 9536fa0ae0 user: drh tags: trunk) | |
| 11:34 | Refactoring various names. No changes in the resulting machine code. (check-in: 7bb08b1bfc user: drh tags: trunk) | |

| 20:31 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: 172a864d14 user: drh tags: trunk) | |
| 20:08 | Fix corner cases involving corrupt varint values in record headers. (Closed-Leaf check-in: 3189116b42 user: drh tags: btree-opt) | |
| 18:24 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: faab0ed928 user: drh tags: btree-opt) | |
| 17:19 | Add the MemPage.xParseCell method and provide various implementations (variations on the former btreeParseCellPtr()) depending on the page type. (check-in: 41d03d883c user: drh tags: trunk) | |
| 15:07 | Make cellSizePtr() a method on the MemPage object, with alternative implementations depending on the page type. This results is a small performance improvement and size reduction. (check-in: 02f7e9d7d7 user: drh tags: trunk) | |

| 23:53 | Fix an uninitialized variable in os_unix.c. (check-in: 822a0283c6 user: drh tags: trunk) | |
| 19:06 | Fix an assert() failure that could occur if compiling with OMIT_SHARED_CACHE. (check-in: 3e76a9f2c0 user: dan tags: experimental) | |
| 18:12 | Change the name of IOCAP_SAFE_DELETE to IOCAP_UNDELETABLE_WHEN_OPEN. Have the xDeviceCharacteristics() method of the win32 VFS return this flag. (check-in: 5a5ff4e3e4 user: dan tags: experimental) | |
| 17:26 | Add tests to pager1.test and pagerfault.test. (check-in: f5df83fd87 user: dan tags: experimental) | |
| 15:10 | Change the unix VFS to always allocate shared-memory using a file in the same directory as the database. Otherwise, a chroot might cause different processes to use different shared memory files resulting in database corruption. (check-in: 2241788bc8 user: drh tags: trunk) | |
| 11:30 | Add tests to pager1.test and pagerfault.test. (check-in: 58c0b5bfed user: dan tags: experimental) | |
