Refactor the "configure" script used to help build SQLite from canonical sources, to fix bugs, improve performance, and make the code more maintainable: This does not affect the "configure" script in the sqlite3-autoconf-NNNNNNN.tar.gz "amalgamation tarball", only the canonical sources. The build system for the amalgamation tarball is unchanged. If you are using the amalgamation tarball, nothing about this change log entry applies to you. The key innovation here is that Autosetup is now used instead of GNU Autoconf. That seems like a big change, but it is really just an implementation detail. The ./configure script is coded very differently, but should work the same as before. One advantage of the new configure is that you no longer need to install TCL in order to build most SQLite targets. TCL is still required to run tests or to build accessory programs (like sqlite3_analyzer) that use TCL, but it is not required for most common targets. Hence, as of this release, the only build dependencies are a C compiler and "make" or "nmake". Improved EXPLAIN QUERY PLAN output for covering indexes. Allow a two-argument version of the iif() SQL function. Also allow if() as an alternative spelling for iif(). Add the ".dbtotxt" command to the CLI. Add the SQLITE_IOCAP_SUBPAGE_READ property to the xDeviceCharacteristics method of the sqlite3_io_methods object. Add the SQLITE_PREPARE_DONT_LOG option to sqlite3_prepare_v3() that prevents warning messages being sent to the error log if the SQL is ill-formed. This allows sqlite3_prepare_v3() to be used to do test compiles of SQL to check for validity without polluting the error log with false messages. Increase the minimum allowed value of SQLITE_LIMIT_LENGTH from 1 to 30. Added the SQLITE_FCNTL_NULL_IO file control. Extend the FTS5 auxiliary API xInstToken() to work with prefix queries via the insttoken configuration option and the fts5_insttoken() SQL function. Increase th |

Fix a problem in text-to-floating-point conversion for SQLite that can cause values between '1.8446744073709550592eNNN' and '1.8446744073709551609eNNN' for any exponent NNN to be rendered incorrectly. In other words, some numeric text values where the first 16 significant digits are '1844674407370955' might be converted into the wrong floating-point value. See forum thread 569a7209179a7f5e. This problem only arises on x64 and i386 hardware. The problem was introduced in 3.47.0. Other minor bug fixes. |

Fix the makefiles so that they once again honored DESTDIR for the "install" target. Add the SQLITE_IOCAP_SUBPAGE_READ capability to the VFS, to work around issues on some non-standard VFSes caused by making SQLITE_DIRECT_OVERFLOW_READ the default in version 3.45.0. Fix problems with line endings in the new sqlite3_rsync.exe utility on Windows. Fix incorrect answers to certain obscure IN queries caused by new query optimizations added in the 3.47.0 release. Other minor bug fixes. |

Allow arbitrary expressions in the second argument to the RAISE function. If the RHS of the ->> operator is negative, then access array elements counting from the right. Fix a problem with rolling back hot journal files in the seldom-used unix-dotfile VFS. FTS5 tables can now be dropped even if they use a non-standard tokenizer that has not been registered. Fix the group_concat() aggregate function so that it returns an empty string, not a NULL, if it receives a single input value which is an empty string. Enhance the generate_series() table-valued function so that it is able to recognize and use constraints on its output value. Preupdate hooks now recognize when a column added by ALTER TABLE ADD COLUMN has a non-null default value. Performance optimizations: Improved reuse of subqueries associated with the IN operator, especially when the IN operator has been duplicated due to predicate push-down. Use a Bloom filter on subqueries on the right-hand side of the IN operator, in cases where that seems likely to improve performance. Ensure that queries like "SELECT func(a) FROM tab GROUP BY 1" only invoke the func() function once per row. No attempt is made to create automatic indexes on a column that is known to be non-selective because of its use in other indexes that have been analyzed. Adjustments to the query planner so that it produces better plans for star queries with a large number of dimension tables. Add the "order-by-subquery" optimization, that seeks to disable sort operations in outer queries if the desired order is obtained naturally due to ORDER BY clauses in subqueries. The "indexed-subtype-expr" optimization strives to use expressions that are part of an index rather than recomputing the expression based on table values, as long as the query planner can prove that the subtype of the expression will never be used. Miscellaneous coding tweaks for faster runtimes. Enhancements to SQLite-related command-line programs: Ad |

Improved robustness while parsing the tokenize= arguments in FTS5. Forum post 171bcc2bcd. Enhancements to covering index prediction in the query planner. Add early detection of over-prediction of covering indexes so that sqlite3_prepare() will return an error rather than just generate bad bytecode. Forum post e60e4c295d22f8ce. Do not let the number of terms on a VALUES clause be limited by SQLITE_LIMIT_COMPOUND_SELECT, even if the VALUES clause contains elements that appear to be variables due to double-quoted string literals. Fix the window function version of group_concat() so that it returns an empty string if it has one or more empty string inputs. In FTS5 secure-delete mode, fix false-positive integrity-check reports about corrupt indexes. Syntax errors in ALTER TABLE should always return SQLITE_ERROR. In some cases, they were formerly returning SQLITE_INTERNAL. JavaScript/WASM: Fix a corruption-causing bug in the JavaScript "opfs" VFS. Work around a couple of browser-specific OPFS quirks. Other minor fixes. |
