| 14:40 | Change RTREE so that the sqlite3_blob object is closed whenever the cursor count drops to zero and there is not a pending write transaction. (check-in: 9bb4eafe1a user: drh tags: rtree-sqlite3_blob) | |
| 02:28 | Use the sqlite3_blob interface for reading values from the %_node shadow table in RTREE. This is a work in progress. There are still some minor problems. (check-in: fc4917d730 user: drh tags: rtree-sqlite3_blob) | |

|
2017-01-28
| ||
| 20:46 | In the amalgamation, allocate the parser engine object from stack rather than from heap, for improved performance. This only happens in the amalgamation, since otherwise the sqlite3RunParser() routine does not know the object size. (check-in: 4fe879d4b5 user: drh tags: trunk) | |
| 19:53 | Fix a couple comment typos. No changes to code. (check-in: 2a2e7d86b2 user: mistachkin tags: trunk) | |

|
2017-01-27
| ||
| 19:27 | Add the sha1.c loadable extension that implements the sha1() and sha1_query() SQL functions. (check-in: 24e77c1cef user: drh tags: trunk) | |
| 17:02 | Fix a problem causing the pre-update hook to be invoked by DROP TABLE statements. (check-in: fbb6bf1b69 user: dan tags: trunk) | |
| 16:39 | Merge all recent trunk enhancements into the apple-osx branch. (check-in: 0e14fe1b98 user: drh tags: apple-osx) | |

| 01:52 | In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". (check-in: 58f02e6eae user: drh tags: trunk) | |
| 01:25 | Another micro-optimization in accessPayload(). Slightly smaller and faster. (check-in: c012619b65 user: drh tags: trunk) | |
| 01:13 | Performance optimization in accessPayload(). (check-in: ebb1fd98d4 user: drh tags: trunk) | |
| 00:31 | Simplify the accessPayload() routine so that it always populates the overflow page cache. In the one case where populating the page cache can lead to problems, simply invalidate the cache as soon as accessPayload() returns. This simplification reduces code size and helps accessPayload() to run a little faster. This backs out the eOp==2 mode of accessPayload() added by check-in [da59198505]. (check-in: 68e7a8c676 user: drh tags: trunk) | |
|
2017-01-26
| ||
| 21:30 | Remove an unreachable branch in the error handling logic for sqlite3BtreePayloadChecked(). (check-in: 293bf3ed7e user: drh tags: trunk) | |

| 17:26 | Remove the obsolete lastRowid cache from the sqlite3VdbeExec() for a size reduction and performance improvement. (check-in: b480318465 user: drh tags: trunk) | |

| 01:54 | Enhancements to the kvtest utility program. Add the --jmode option. Improved output formatting. (check-in: 62a4851ccf user: drh tags: trunk) | |
| 00:58 | Modify the ICU extension to use a static initializer, as VC++ complains about a dynamic initialization. Maybe the dynamic structure initialization is a GCC extension. This fixes a problem identified on the SQLite mailing list by Ziemowit Laski. (check-in: 50e60cb44f user: drh tags: trunk) | |
|
2017-01-25
| ||
| 20:55 | Trim NULL values off the end of records when the SQLITE_ENABLE_NULL_TRIM compile-time option is used. Increase the size of the P5 operand to 16 bits. Fix a problem with short records in the sessions extension. (check-in: 4801bd59a0 user: drh tags: trunk) | |

| 14:58 | Experimental enhancement to automatically trim NULL values from the end of records, for a reduced disk footprint. This change also involves increasing the P5 operand from 8 to 16 bits. (check-in: 118ded403b user: drh tags: trim-nulls) | |
| 14:38 | Ensure that sqlite3_blob_reopen() correctly handles short rows. Fix for ticket [e6e962d6b0f06f46e]. (check-in: 8cd1a4451c user: drh tags: trunk) | |
