16:33 | Create the new TK_ASTERISK token to represent the "*" in "SELECT *". Formerly that operator was TK_ALL, which was also used for UNION ALL. Less confusion if they operator symbols are distinct. (check-in: 201ac6d4 user: drh tags: trunk) | |
14:11 | If compiled with SQLITE_ENABLE_HIDDEN_COLUMNS, then columns in ordinary tables and views that have names beginning with "__hidden__" are omitted from the "*" expansion in SELECT statements and from the automatic list of columns following the table name in an INSERT INTO statement. (check-in: 011904ca user: drh tags: trunk) | |

18:43 | If a table column name begins with "__hidden__" then do not include that column in "*" expansions in SELECT statements, nor fill in that column in an INSERT INTO that omits the column list. This branch is a proof-of-concept only and is not intended to ever be merged into trunk. (check-in: 2dbffb3a user: drh tags: hidden-columns-in-tables) | |

08:54 | In the shell tool, avoid testing if (sqlite3_vfs.xGetCurrentInt64) is NULL for a version 1 VFS. This field is only defined for version 2 and greater. (check-in: ad5fcaa5 user: dan tags: trunk) | |

18:43 | Fix missing word in a documentation comment. No changes to code. (check-in: ed24d302 user: mistachkin tags: trunk) | |
18:08 | Add a hack to debug out a description of the WHERE clause of a SELECT (or other) statement. Use this in script tool/schemalint.tcl to automatically recommend indexes that might speed up specific queries. (check-in: c6fa01c2 user: dan tags: schemalint) | |

20:13 | Work around a sign-extension bug in the optimizer on the HP C compiler that comes with HP/UX. (check-in: 46c36b15 user: drh tags: trunk) | |
20:04 | Test changes: Omit numindex1.test from valgrind, since valgrind uses a none-standard floating-point processor which gives inconsistent answers. Run one releasetest.tcl module using LONGDOUBLE_TYPE=double. (check-in: d421efbf user: drh tags: trunk) | |
19:53 | Enforce consistent comparison results between integer and floating point values. Fix for ticket [38a97a87a6e4e83]. (check-in: 849e686d user: drh tags: trunk) | |

12:50 | Have fts5 load its configuration from the xConnect() method is invoked. This ensures that the very first query run uses the correct value of the 'rank' option. (check-in: 33e6606f user: dan tags: trunk) | |

22:30 | Improvements and simplifications to the equality seek logic. Tests are adjusted so that they all pass now. (Closed-Leaf check-in: 997ce6c9 user: drh tags: seekeq-experiment) | |
21:49 | Fix typo in help information for an FTS5 script. (check-in: 777ae800 user: mistachkin tags: trunk) | |
20:25 | The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. This check-in adds a flag to OP_SeekGE such that it fails immediately if the key is not equal, then jumps over the OP_IdxGT, saving a call to the key comparison functions. Consider this check-in a proof-of-concept. It needs improvement before going on trunk. Some tests fail, but only because they new use fewer key comparisons than expected (which is a good thing!). (check-in: 32e31b9b user: drh tags: seekeq-experiment) | |
18:09 | Add the 'hashsize' configuration option to fts5, for configuring the amount of memory allocated to the in-memory hash table while writing. (check-in: 44548009 user: dan tags: trunk) | |

16:34 | In releasetest.tcl, run larger test first if --jobs is greater than 1. Run smaller tests cases first if --jobs is 1. (check-in: 3fece5d0 user: drh tags: trunk) | |
13:03 | Exclude cffault.test and symlink.test from the (incompatible) inmemory_journal permutation. (check-in: 4f16e968 user: drh tags: trunk) | |
