| 20:56 | Merge trunk fixes for "x IN (?)" handling. check-in: eca35871 user: drh tags: orderby-planning | |
| 19:04 | Remove a testcase() that is now always true due to the "x IN (?)" optimization. Add an ALWAYS() around a conditional in the parser that cannot be false. check-in: d5a1530b user: drh tags: trunk | |
| 18:56 | Only use the direct-overflow-read optimization if all data from the overflow page in question is being read. check-in: d8e1f75d user: dan tags: overflow-pgno-cache | |
| 18:45 | Fix the EXPLAIN indenter in the command-line shell to correctly handle NextIfOpen and PrevIfOpen opcodes. check-in: 01944c53 user: drh tags: trunk | |
| 17:03 | The "x IN (?)" optimization in check-ins [2ff3b25f40] and [e68b427afb] is incorrect, as demonstrated by the in4-5.1 test case in this check-in. The "COLLATE binary" that was being added to the RHS of IN was overriding the implicit collating sequence of the LHS. This change defines the EP_Generic expression node property that blocks all affinity or collating sequence information in the expression subtree and adds that property to the expression taken from RHS of the IN operator. check-in: 2ea4a9f7 user: drh tags: trunk | |
| 15:14 | Fix harmless compiler warnings. check-in: b1435f26 user: drh tags: trunk | |
| 14:56 | Previous check-in is not quite correct. "x IN (?)" is not exactly the same as "x==?" do to collation and affinity issues. The correct converstion should be to "x==(+? COLLATE binary)". The current check-in fixes this problem and provides test cases. Ticket [e39d032577df69] check-in: 2ff3b25f user: drh tags: trunk | |
| 13:26 | Convert expressions of the form "X IN (?)" with exactly one value on the RHS of the IN into equality tests: "X=?". Add test cases to verify that statements work correctly on this corner case. Fix for ticket [e39d032577df6942]. check-in: e68b427a user: drh tags: trunk | |
| 12:36 | One possible fix for the [e39d032577d] problem it to replace the failing assert() with a testcase() as shown here. Closed-Leaf check-in: eae6dfbe user: drh tags: tkt-e39d0325 | |
| 12:17 | Fix an unnecessarily obtuse use of a bitmask flag. check-in: ca314081 user: drh tags: trunk | |
| 09:42 | Add a test to ensure os_unix.c works with 64KiB OS pages. Closed-Leaf check-in: e3d2be3b user: dan tags: shm-mapping-fix | |
| 08:59 | Add an experimental fix to avoid attempting to mmap memory from an offset that is not a multiple of the system page size on systems with page sizes larger than 32KB. check-in: 6f3a5c24 user: dan tags: shm-mapping-fix | |

| 23:42 | Merge the vdbesort.c optimization from trunk. check-in: e4bfffb9 user: drh tags: orderby-planning | |
| 23:24 | Fix query planner weights associated with choosing block-sorting. Fix block sorting of tables with collating functions. Fix various test cases. All "veryquick" tests are now passing, though more tests need to be added. check-in: 01afbf97 user: drh tags: orderby-planning | |
| 20:01 | Avoid some unnecessary calls to sqlite3VdbeRecordUnpack() that were being made when merging data from two or more temp files together in vdbesort.c check-in: 707ea170 user: dan tags: trunk | |
| 17:41 | Make it possible for block-sort to use the OP_SorterOpen sorter in addition to a generic OP_OpenEphemeral. check-in: 7ce2daaf user: drh tags: orderby-planning | |
| 16:56 | Fix a problem in the block-sort logic that can arise if the VDBE opcode array is resized while the block-sort logic is being coded. "make test" now runs to completion, though there are still 17 failures. check-in: 62f3a220 user: drh tags: orderby-planning | |
| 15:17 | Avoid reusing temporary registers in co-routines when doing block-sorting. check-in: 463d921b user: drh tags: orderby-planning | |
| 14:30 | Make sure the where.c query planner never reports that the number of ORDER BY terms that are satisfied by indices is negative. check-in: b186d8d1 user: drh tags: orderby-planning | |
| 14:10 | First attempt at getting block-sort to work. This is an incremental check-in. There are many problems still to be worked out. check-in: 59742dd4 user: drh tags: orderby-planning | |

| 20:33 | Make the partial-ORDER-BY information in the query planner available to the SELECT code generator. Still doesn't make a difference in the generated code. check-in: e258df23 user: drh tags: orderby-planning | |
| 18:59 | Adjust the query planner to keep track of the number of ORDER BY terms satisfied. Still doesn't do anything with this information. Some tests fail after this check-in, but all failures are believed to be benign. The failures will be addressed at a later stage. check-in: 59d49b7f user: drh tags: orderby-planning | |

| 23:52 | Minor simplifications to the "zeroPage()" routine in btree.c. check-in: cc8f10bc user: drh tags: trunk | |
| 21:31 | Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. check-in: 56bc5ce8 user: drh tags: trunk | |
| 14:43 | Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Fix for ticket [c34d0557f740c45070]. check-in: 5d01426d user: drh tags: trunk | |

| 16:22 | Updates to the command-line shell. Simplify the banner message. Add the ".save" command as an alias for ".backup". When starting with no arguments, include a banner message warning that the database is transient and in-memory and mention the ".open" command. check-in: f5ad1e1b user: drh tags: trunk | |

| 23:20 | Do away with the "multi-register pseudo-table" abstration. Instead, just use an OP_SCopy to load results directory from the result registers of the co-routine. check-in: 1e64dd78 user: drh tags: trunk | |

| 01:40 | Change the OP_Trace opcode to OP_Init and give it the ability to jump to the initialization code at the bottom of the program, thus avoiding the need for an extra OP_Goto. check-in: 192dea97 user: drh tags: trunk | |

| 13:20 | Add the OP_Undef and OP_IsUndef opcodes. With these, use the first register in the result register range as the flag to indicate EOF on an INSERT from a SELECT, rather than allocating a separate boolean register for that task. check-in: 6fb74485 user: drh tags: coroutine-refactor | |

| 23:45 | Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output. This is not an issue for standard SQLite since ephemeral tables there are always ordered, regardless of the hint. It only affects systems that substitute an alternative storage engine. check-in: f2504089 user: drh tags: trunk | |
