3470200
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.
3470100
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.
3470000
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.
