| 20:21 | Faster memory allocation from lookaside by not trying to keep track of the number of outstanding allocations, and rather computing that value only when requested. (check-in: a06263f1ef user: drh tags: trunk) | |
|

| ||
| 17:00 | Add the --enable-update-limit option to the ./configure script. (check-in: 64a8ae6838 user: drh tags: trunk) | |
| 16:11 | Avoid unnecessary mutexes in the pcache1 implementation in the common case where no auxiliary page cache memory is configured. (check-in: 1ba051e34d user: drh tags: trunk) | |
| 15:51 | Remove the rarely-used scratch memory allocator. This makes the code smaller, faster, and easier to maintain. In place of the scratch allocator, add the SQLITE_CONFIG_SMALL_MALLOC configuration option that provides a hint to SQLite that large memory allocations should be avoided. (check-in: 54b000246c user: drh tags: trunk) | |
| 14:33 | Backport changes to shell.c into shell.c.in. (check-in: 2348045fbc user: drh tags: trunk) | |
| 11:12 | Fix the ".dump", ".schema", and ".fullschema" commands of the command-line shell so that they work even if PRAGMA empty_result_callbacks is enabled. Fix for ticket [02f0f4c54f281]. (check-in: cf0d3715ca user: drh tags: trunk) | |

| 13:02 | Convert a branch made unreachable by [59560d07] into an assert(). (check-in: 2738b8db3c user: drh tags: trunk) | |
| 11:44 | Improve the internal mechanism used to keep track of what kind of syncing to do for WAL transaction commits and checkpoint operations. Use the checkpoint-style of syncing to sync the header of a new or restarted WAL file. (check-in: e8d23afe84 user: drh tags: trunk) | |
| 09:17 | Avoid returning duplicate rows in experimental pragmas "pragma_list", "module_list" and "function_list". (check-in: b79cc8dc88 user: dan tags: trunk) | |
| 01:14 | Update the mechanism used to keep track of what kind of syncing to do for WAL transaction commits and checkpoint operations. Use the checkpoint-style of syncing to sync the header of a new or restarted WAL file. (Closed-Leaf check-in: bf65dae8d4 user: drh tags: wal-sync-refactor) | |

| 20:54 | Fix an incorrect hyperlink in a comment. (check-in: 25292b9a4e user: drh tags: trunk) | |
| 15:43 | Fixes to documentation about SQLITE_OPEN_URI. (check-in: 7ec72314d6 user: drh tags: trunk) | |
| 13:55 | Make sure the sqlite3_result_pointer() interface does not leave a VM register in an inconsistent state. Fix for ticket [7486aa54b968e9b5]. Test cases are in TH3. (check-in: d2f9230c5c user: drh tags: trunk) | |

| 23:09 | Performance optimization to pageFindSlot() in the b-tree layer. (check-in: 59560d079f user: drh tags: trunk) | |
| 20:36 | Size and performance optimization to dropCell() and freeSpace(). (check-in: bc1ec123ce user: drh tags: trunk) | |
| 14:45 | Smaller and faster implementation of the fillInCell() routine. (check-in: 77074990ed user: drh tags: trunk) | |
|
2017-08-22
| ||
| 21:23 | Update documentation to make it clear that SQLITE_SOURCE_ID and sqlite3_sourceid() might changes if the source code is edited. (check-in: e69c0c8770 user: drh tags: trunk) | |
| 21:07 | Less dramatic changes to the source-id following an edit. Modify the way that the amalgamation is constructed to give it the opportunity to detect changes and modify the source-id. (check-in: 564c7340a3 user: drh tags: trunk) | |
| 19:54 | Modify the SQLITE_SOURCE_ID if the source code has changed in any way since the previous check-in. (check-in: 515d6a8377 user: drh tags: trunk) | |

| 19:43 | Attempting to fix the source-id generator so that it works for out-of-tree builds. (check-in: 5a037ac2da user: drh tags: mksourceid) | |
| 19:19 | Add the "mksourceid" program to the build process. That program changes the SQLITE_SOURCE_ID if the source tree has been modified in any way. (check-in: d4c05e04f7 user: drh tags: mksourceid) | |
| 15:21 | Fix error tests in seldom-used compile-time branches of the unix backend. (check-in: 885c2b44a4 user: drh tags: trunk) | |

| 21:14 | Size and performance optimization the readDbPage() routine in the pager. (check-in: ca9e1875c3 user: drh tags: trunk) | |
| 16:09 | For the unix VFS, avoid an unnecessary stat() system call prior to opening any file in the common case where there are no unused file descriptors. (check-in: 3075cfa074 user: drh tags: trunk) | |
| 14:34 | Combine the OP_CreateTable and OP_CreateIndex opcodes of the bytecode engine into a single OP_CreateBtree opcode. This simplifies the implementation and makes the bytecode programs clearer. (check-in: eb1202b5e4 user: drh tags: trunk) | |
| 08:29 | Only use indexes on expressions to optimize ORDER BY and GROUP BY if the collation sequence matches. Possible fix for [e20dd54a]. (check-in: 37e1900880 user: dan tags: trunk) | |

| 20:53 | Use the __builtin_clzll() function of gcc to improve the performance and reduce the size of the sqlite3LogEst() routine. (check-in: a42a438cbb user: drh tags: trunk) | |
| 19:23 | Small optimization in the Expr tree walker. (check-in: 264a5e1b75 user: drh tags: trunk) | |
| 18:54 | Size optimization in the authorizer error message generation logic. (check-in: 0367a4d586 user: drh tags: trunk) | |
| 18:23 | In sqlite3ViewGetColumnNames(), return the number of errors, not an error code. (check-in: f13682ea23 user: drh tags: trunk) | |
| 18:17 | The RTREE extension should return SQLITE_CORRUPT_VTAB, not just SQLITE_CORRUPT when it encounters incorrectly formatted shadow tables. (check-in: 0712f057ef user: drh tags: trunk) | |
| 14:47 | Remove an unnecessary branch from the [be436a7f4587ce517ddc] fix. (check-in: fb6ca99b88 user: drh tags: trunk) | |
| 14:12 | Add test cases for ticket [be436a7f4587ce517] using virtual table modules fts5 and rtree. (check-in: 2101b42087 user: dan tags: trunk) | |

| 19:20 | Avoid a test for CURTYPE_BTREE in sqlite3VdbeCursorMoveto() in order to reduce the size and improve the performance of OP_Column. (check-in: f078deb251 user: drh tags: trunk) | |
| 14:16 | Remove an unnecessary local variable from OP_Column, for a small size reduction and performance increase. (check-in: 3954390328 user: drh tags: trunk) | |
| 11:04 | Performance improvement in the OP_Column opcode. (check-in: dc98a92f32 user: drh tags: trunk) | |
|

| 03:46 | Btree optimization: New field BtCursor.pPage that points to the current page, saving a single pointer dereference on each access. (check-in: 373b71d19c user: drh tags: trunk) | |
|
2017-08-14
| ||
| 23:53 | Minor size and performance optimization to sqlite3BtreeCloseCursor(). (check-in: 1696933884 user: drh tags: trunk) | |
| 18:13 | Change the internal btree routine moveToRoot() to return SQLITE_EMPTY if the table is empty or if it has pgnoRoot==0. This simplifies the callers, making them smaller and faster. The SQLITE_EMPTY result code is intercepted and changed into SQLITE_OK before surfacing in an API. (check-in: 240d57143d user: drh tags: trunk) | |
| 17:03 | Fix harmless indentation error. (check-in: 25e92baaae user: drh tags: trunk) | |
| 14:53 | Sometimes a TK_COLUMN Expr node can have Expr.pTab==0 if it is a reference to an expression column in an index on an expression. Fix for ticket [aa98619ad08ddcab]. (check-in: d0da791ba0 user: drh tags: trunk) | |
