| 19:07 | Make the sqlite3_table_column_metadata() interface available by default and without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option. Other sqlite3_column_* interfaces that have a run-time penalty even if they are unused still require the SQLITE_ENABLE_COLUMN_METADATA option at compile-time. (check-in: 4f7549ff92 user: drh tags: trunk) | |
| 15:12 | Add the SQLITE_REVERSE_UNORDERED_SELECTS compile-time option that causes the "PRAGMA reverse_unordered_selects" setting to be on by default. (check-in: 75a803e694 user: drh tags: trunk) | |

| 21:24 | Draw the TreeView debugging graphs using unicode box-drawing characters. (Closed-Leaf check-in: 0efc6859d1 user: drh tags: box-character-graph) | |
| 19:04 | Improvements to the new syntax-tree output routines: Omit the "END SELECT" mark and instead terminate the graph at the last item. Increase the maximum tree depth to 100. (check-in: 5ce05757aa user: drh tags: trunk) | |
| 17:31 | Enable the query planner to deal with WHERE clauses that have OR terms nested within AND terms that are nested within OR terms. Also remove an unused function declaration. (check-in: b6b289182f user: drh tags: trunk) | |
| 17:03 | Further enhancements to the "wheretrace" debugging output. (check-in: 670993eb81 user: drh tags: trunk) | |
| 14:14 | Enhanced debug output for OR-logic in the query loop optimizer. (check-in: 2e375eae47 user: drh tags: trunk) | |
| 13:46 | Show tree diagrams of data structures in the debugging output when the 0x100 bit is set on sqlite3WhereTrace or sqlite3SelectTrace. (check-in: 92e0b4bd4d user: drh tags: trunk) | |
| 12:33 | Remove the SQLITE_ENABLE_TREE_EXPLAIN compile-time option. Add alternative debugging display routines: sqlite3TreeViewExpr(), sqlite3TreeViewExprList(), and sqlite3TreeViewSelect(). (check-in: 4ff51325d6 user: drh tags: trunk) | |

| 18:47 | Add the OPFLAG_MULTICOLUMN flag to the OP_Column opcode. Rearrange OP_Column instructions to take advantage of the new flag for a small performance increase (Leaf check-in: 5e5d6e8680 user: drh tags: faster-OP_Column) | |
| 15:42 | Fix the header comment in sqlite3VdbeDeletePriorOpcode(). No changes to code. (check-in: 7fb1626866 user: drh tags: trunk) | |
| 15:00 | Ensure that the OP_Prev opcode verifies that content has not been deleted out from under the cursor. Fix for ticket [209d31e3161b9e9ff]. (check-in: 414f0d6a64 user: drh tags: trunk) | |

| 20:45 | Change the names of the stream interface APIs to be of the form "_strm" instead of "_str". In other words, added an "m" to the end, to try to make it clear that we are talking about a "stream" and not a "string. (check-in: 1f44bfdc23 user: drh tags: sessions) | |
| 19:51 | Merge recent trunk changes (performance enhancements) into the sessions branch. (check-in: 497367cb57 user: drh tags: sessions) | |
| 05:00 | Reduce the amount of memcpy() required by defragmentPage(). (check-in: 3edab9957c user: drh tags: defrag-opt) | |
|

| 18:30 | Add an assert() to verify the last-row-id for the database just prior to calling a SQL function. (check-in: d026f0c944 user: mistachkin tags: trunk) | |
| 02:41 | Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. (check-in: 8391351583 user: drh tags: trunk) | |
| 01:10 | If an SQL function makes a recursive call to do an INSERT into the same database, make sure that the last_insert_rowid() for that INSERT is recorded. (check-in: e93aecc090 user: drh tags: trunk) | |

| 17:42 | Minor code reformatting and comment change, to improve clarity. No logic changes. (check-in: baeb72a356 user: drh tags: trunk) | |
| 13:17 | Simplifications to the SQL function and aggregate calling procedures. (check-in: 3467049a17 user: drh tags: trunk) | |
| 12:31 | Simplification to the random rowid picking logic that begins running when the maximum possible rowid has already been used. (check-in: 1330c72e17 user: drh tags: trunk) | |
| 11:08 | Still more performance enhancements to the LIKE and GLOB operators. (check-in: 6c8924cacc user: drh tags: trunk) | |
| 03:51 | More performance optimization for the LIKE and GLOB operators. (check-in: 5ab1023d6c user: drh tags: trunk) | |
| 02:44 | Change that might allow SQLite to build and work using the EBCDIC character set. (check-in: ef30e0352b user: drh tags: trunk) | |
| 00:56 | Size reduction and performance improvement in the LIKE and GLOB operators. (check-in: b2c89ef49c user: drh tags: trunk) | |

| 19:47 | Have each open database allocate its pTmpSpace when the first write cursor is opened, rather than on each insert or delete, for a small space savings and performance boost. (check-in: 99323552c0 user: drh tags: trunk) | |
| 18:31 | Small performance and size optimization for btreeUnlockIfUnused(). (check-in: 13c746f85d user: drh tags: trunk) | |
| 13:20 | Do not allow parameters in a DEFAULT clause of a CREATE TABLE statement. Ticket [78c0c8c3c9f7c1]. (check-in: 1ad2bc1ed4 user: drh tags: trunk) | |
| 04:38 | Experiment using linear interpolation, instead of a strict binary search, when looking for integer-keyed rows on a single b-tree page. The experiment was not successful. The number of key comparisons is reduced by about 15%, but the added complexity of the search logic causes an overall reduction in performance. The patch is saved for historical reference only. (Closed-Leaf check-in: c705cf856d user: drh tags: linear-interpolation) | |
| 02:05 | Have the clearCell() routine return the cell size to the caller, rather than have the caller make a separate call to cellSizePtr(). (check-in: f21d217583 user: drh tags: trunk) | |
| 01:23 | Shorten all lines of source code in btree.c to at most 80 characters. No logical changes. (check-in: 5dd41cdbfe user: drh tags: trunk) | |
| 00:59 | Add the MemPage.noPayload boolean and use it to help cellSizePtr() and btreeParseCellPtr() run faster. (check-in: 8e3375313e user: drh tags: trunk) | |
|

| 23:12 | Remove an unused C-preprocessor macro. No functional changes to the code. (check-in: f480582cca user: drh tags: trunk) | |
| 22:36 | Avoid calling btreeParseCellPtr() from within fillInCell() since most of what btreeParseCellPtr() computes is ignored by fillInCell(). Instead, have fillInCell() compute the values it needs inline. Performance improvement. (check-in: 4147f6671e user: drh tags: trunk) | |
| 21:25 | Simplify the CellInfo structure for a size reduction and performance improvement. (check-in: bf59df66b3 user: drh tags: trunk) | |
| 18:30 | Add the "multiplex_truncate" PRAGMA to the multiplexor extension, for querying and setting the truncate flag on a database connection. (check-in: d2962a5f38 user: drh tags: trunk) | |
| 01:40 | Adjust skip-scan cost estimates slightly so that a full table scan is preferred over a skip-scan to a column with only two distinct values. (check-in: ae9a42b268 user: drh tags: trunk) | |

| 20:38 | Fix to payload size overflow detection in the cellSizePtr() change of the previous check-in. (check-in: 7609744014 user: drh tags: trunk) | |
| 19:51 | Size reduction and substantial performance increase for cellSizePtr(). (check-in: bc8bbf3207 user: drh tags: trunk) | |
| 14:30 | Tune the query planner to be more aggressive about using automatic indexes on views and subqueries for which there is not opportunity to declare a persistent schema index. (check-in: 41de1643bf user: drh tags: trunk) | |
| 03:22 | Disable shared memory operations using the unix-nolock VFS. (check-in: 10a6e51049 user: drh tags: trunk) | |
