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.

Log message:
sqlite3: updated to 3.45.2

version 3.45.2 (2024-03-12):

Fix an error in UPSERT, introduced by enhancement 3a in version 3.35.0 \ 
(2021-03-12), that could cause an index to get out-of-sync with its table. Forum \ 
thread 919c6579c8.
Reduce the scope of the NOT NULL strength reduction optimization that was added \ 
as item 8e in version 3.35.0 (2021-03-12). The optimization was being attempted \ 
in some contexts where it did not work, resulting in incorrect query results. \ 
Forum thread 440f2a2f17.

the previous patch release. See the timeline for details.

Log message:
sqlite3* lemon: updated to 3.45.1

version 3.45.1 (2024-01-30):

Restore the JSON BLOB input bug, and promise to support the anomaly in \ 
subsequent releases, for backward compatibility.
Fix the PRAGMA integrity_check command so that it works on read-only databases \ 
that contain FTS3 and FTS5 tables. This resolves an issue introduced in version \ 
3.44.0 but was undiscovered until after the 3.45.0 release.
Fix issues associated with processing corrupt JSONB inputs:
Prevent exponential runtime when converting a corrupt JSONB into text.
Fix a possible read of one byte past the end of the JSONB blob when converting a \ 
corrupt JSONB into text.
Enhanced testing using jfuzz to prevent any future JSONB problems such as the above.
Fix a long-standing bug in which a read of a few bytes past the end of a \ 
memory-mapped segment might occur when accessing a craftily corrupted database \ 
using memory-mapped database.
Fix a long-standing bug in which a NULL pointer dereference might occur in the \ 
bytecode engine due to incorrect bytecode being generated for a class of SQL \ 
statements that are deliberately designed to stress the query planner but which \ 
are otherwise pointless.

SQLite Release 3.45.0 On 2024-01-15

Added the SQLITE_RESULT_SUBTYPE property for application-defined SQL functions. \ 
All application defined SQL functions that invokes sqlite3_result_subtype() must \ 
be registered with this new property. Failure to do so might cause the call to \ 
sqlite3_result_subtype() to behave as a no-op. Compile with \ 
-DSQLITE_STRICT_SUBTYPE=1 to cause an SQL error to be raised if a function that \ 
is not SQLITE_RESULT_SUBTYPE tries invokes sqlite3_result_subtype(). The use of \ 
-DSQLITE_STRICT_SUBTYPE=1 is a recommended compile-time option for every \ 
application that makes use of subtypes.
Enhancements to the JSON SQL functions:
All JSON functions are rewritten to use a new internal parse tree format called \ 
JSONB. The new parse-tree format is serializable and hence can be stored in the \ 
database to avoid unnecessary re-parsing whenever the JSON value is used.
New versions of JSON-generating functions generate binary JSONB instead of JSON text.
The json_valid() function adds an optional second argument that specifies what \ 
it means for the first argument to be "well-formed".
Add the FTS5 tokendata option to the FTS5 virtual table.
The SQLITE_DIRECT_OVERFLOW_READ optimization is now enabled by default. Disable \ 
it at compile-time using -DSQLITE_DIRECT_OVERFLOW_READ=0.
Query planner improvements:
Do not allow the transitive constraint optimization to trick the query planner \ 
into using a range constraint when a better equality constraint is available. \ 
(Forum post 2568d1f6e6.)
The query planner now does a better job of disregarding indexes that ANALYZE \ 
identifies as low-quality. (Forum post 6f0958b03b.)
Increase the default value for SQLITE_MAX_PAGE_COUNT from 1073741824 to 4294967294.
Enhancements to the CLI:
Improvements to the display of UTF-8 content on Windows
Automatically detect playback of ".dump" scripts and make appropriate \ 
changes to settings such as ".dbconfig defensive off" and \ 
".dbconfig dqs_dll on".

Log message:
sqlite3: updated to 3.44.2

3.44.1 (2023-11-22):

Change the CLI so that it uses UTF-16 for console I/O on Windows. This enables \ 
proper display of unicode text on old Windows7 machines.
Other obscure bug fixes.

3.44.2 (2023-11-24):

Fix a mistake in the CLI that was introduced by the fix (item 15 above) in 3.44.1.
Fix a problem in FTS5 that was discovered during internal fuzz testing only \ 
minutes after the 3.44.1 release was tagged.
Fix incomplete assert() statements that the fuzzer discovered the day after the \ 
previous release.
Fix a couple of harmless compiler warnings that appeared in debug builds with GCC 16.
