| 19:00 | Make the "nolock" VFS on unix a version-3 VFS so that the sorter can use memory-mapped I/O. (check-in: 3db78d61 user: drh tags: trunk) | |
| 16:56 | Remove a local variable from the OP_Column implementation, resulting in a modest size reduction and a performance increase. (check-in: 6199760d user: drh tags: trunk) | |
| 16:13 | Small size reduction and performance increase for releaseMemArray(). (check-in: 24cd32d6 user: drh tags: trunk) | |
| 16:02 | Updates to comments. No code changes. (check-in: 9b42c3da user: drh tags: trunk) | |
| 15:28 | The OP_Column opcode runs faster and is smaller by manually in-lining the code that persists string values in the output register. (check-in: 36b613cc user: drh tags: trunk) | |
| 04:42 | Add the sqlite3VdbeMemClearAndResize() function. Fix a sorting-index prefilter problem. (check-in: 987a7a21 user: drh tags: trunk) | |
| 02:01 | Make sure that the sorting-index pre-filter recognizes that a rowid reference might be sortable. This fixes a performance regression. (Closed-Leaf check-in: 72727b68 user: drh tags: Cplusplus-comment) | |
| 00:43 | Add the sqlite3VdbeMemClearAndResize() interface to be used in place of sqlite3VdbeMemGrow(). A C++ style comment was left in this check-in by mistake, and so it has been moved into a branch to avoid problems in any future bisects on windows.
