sqlite3: updated to 3.49.1

Prior changes from version 3.49.0 (2025-02-06):

Enhancements to the query planner:
Improve the query-time index optimization so that it works on WITHOUT ROWID tables.
Better query plans for large star-query joins. This fixes three different \ 
performance regressions that were reported on the SQLite Forum.
When two or more queries have the same estimated cost, use the one with the \ 
fewer bytes per row.
Enhance the iif() SQL function so that it can accept any number of arguments \ 
greater than or equal to two.
Enhance the session extension so that it works on databases that make use of \ 
generated columns.
Omit the SQLITE_USE_STDIO_FOR_CONSOLE compile-time option which was not \ 
implemented correctly and never worked right. In its place add the \ 
SQLITE_USE_W32_FOR_CONSOLE_IO compile-time option. This option applies to \ 
command-line tools like the CLI only, not to the SQLite core. It causes Win32 \ 
APIs to be used for console I/O instead of stdio. This option affects Windows \ 
builds only.
Three new options to sqlite3_db_config(). All default to "on".
SQLITE_DBCONFIG_ENABLE_ATTACH_CREATE
SQLITE_DBCONFIG_ENABLE_ATTACH_WRITE
SQLITE_DBCONFIG_ENABLE_COMMENTS
Replace Autotools with Autosetup for the configure script used in the \ 
precompiled amalgamation tarball. The configure script for the canonical source \ 
code was changed to Autosetup in the previous (3.48.0) release. Only the main \ 
SQLite configure script in the amalgamation tarball is changed. The (deprecated) \ 
configuration script use by TEA subdirectory of the amalgamation tarball still \ 
relies on Autotools.
Various minor patches and fixes for problems seen in the 3.48.0 release.

Changes in this specific patch release, version 3.49.1 (2025-02-18):

Improve portability of makefiles and configure scripts.
Fix a bug in the concat_ws() function, introduced in version 3.44.0, that could \ 
lead to a memory error if the separator string is very large (hundreds of \ 
megabytes).
Enhanced the SQLITE_DBCONFIG_LOOKASIDE interface to make it more robust against \ 
misuse.

SQLite Release 3.48.0 On 2025-01-14

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 the maximum number of arguments to an SQL function from 127 to 1000.
Remove vestigial traces of SQLITE_USER_AUTHENTICATION.
Various obscure bug fixes.

Log message:
sqlite3: updated to 3.47.2

version 3.47.2 (2024-12-07):

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.

3.47.1 (2024-11-25):

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.

SQLite Release 3.47.0

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:
Add the experimental sqlite3_rsync program.
Add extension functions median(), percentile(), percentile_cont(), and \ 
percentile_disc() to the CLI.
Add the .www dot-command to the CLI.
The sqlite3_analyzer utility now provides a break-out of statistics for WITHOUT \ 
ROWID tables.
The sqldiff utility avoids creating an empty database if its second argument \ 
does not exist.
Enhance the sqlite_dbpage table-valued function such that INSERT can be used to \ 
increase or decrease the size of the database file.
SQLite no longer makes any use of the "long double" data type, as \ 
hardware support for long double is becoming less common and long double creates \ 
challenges for some compiler tool chains. Instead, SQLite uses Dekker's \ 
algorithm when extended precision is needed.
The TCL Interface for SQLite supports TCL9. Everything probably still works for \ 
TCL 8.5 and later, though this is not guaranteed. Users are encouraged to \ 
upgrade to TCL9.
JavaScript/WASM:
Fix a corruption-causing bug in the JavaScript "opfs" VFS.
Correct "mode=ro" handling for the "opfs" VFS.
Work around a couple of browser-specific OPFS quirks.
FTS5 Changes:
Add the fts5_tokenizer_v2 API and the locale=1 option, for creating custom \ 
locale-aware tokenizers and fts5 tables that may take advantage of them.
Add the contentless_unindexed=1 option, for creating contentless fts5 tables \ 
that store the values of any UNINDEXED columns persistently in the database.
Allow an FTS5 table to be dropped even if it uses a custom tokenizer whose \ 
implementation is not available.

Log message:
sqlite3: updated to 3.46.1

3.46.1 (2024-08-13):

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.

SQLite Release 3.46.0 On 2024-05-23

Enhance PRAGMA optimize in multiple ways, to make it simpler to use:
PRAGMA optimize automatically implements a temporary analysis limit to prevent \ 
excess runtime on large databases.
Added the new 0x10000 bitmask option to check for updates on all tables.
Automatically re-analyze tables that do not have sqlite_stat1 entries.
Enhancements to the date and time functions:
The strftime() SQL function now supports %G, %g, %U, and %V.
New modifiers 'ceiling' and 'floor' control the algorithm used to resolve \ 
ambiguous dates when shifting a date by an integer number of months and/or \ 
years.
The 'utc' and 'localtime' modifiers are now no-ops if SQLite knows that the time \ 
is already in UTC or in the localtime, respectively.
Add support for underscore ("_") characters between digits in numeric \ 
literals.
Add the json_pretty() SQL function.
Query planner improvements:
The "VALUES-as-coroutine" optimization enables INSERT statements with \ 
thousands of rows in the VALUES clause to parse and run in about half the time \ 
and using about half as much memory.
Allow the use of an index for queries like "SELECT count(DISTINCT col) FROM \ 
...", even if the index records are not smaller than the table records.
Improved recognition of cases where the value of an SQL function is constant \ 
because all its arguments are constant.
Enhance the WHERE-clause push-down optimization so that it is able to push down \ 
WHERE clause terms containing uncorrelated subqueries.
Allocate additional memory from the heap for the SQL parser stack if that stack \ 
overflows, rather than reporting a "parser stack overflow" error.
JSON changes:
Allow ASCII control characters within JSON5 string literals.
Fix the -> and ->> operators so that when the right-hand side operand \ 
is a string that looks like an integer it is still treated as a string, because \ 
that is what PostgreSQL does.
Allow large hexadecimal literals to be used as the DEFAULT value to a table column.

sqlite3: updated to 3.45.3

3.45.3 (2024-04-15):

Fix a long-standing bug (going back to version 3.24.0) that might (rarely) cause \ 
the "old.*" values of an UPDATE trigger to be incorrect if that \ 
trigger fires in response to an UPSERT. Forum post 284955a3cd454a15.
Fix a bug in sum() that could cause it to return NULL when it should return \ 
Infinity. Forum post 23b8688ef4.
Other trifling corrections and compiler warning fixes that have come up since \ 
the previous patch release. See the timeline for details.
