sqlite3: updated to 3.32.1

Changes in version 3.32.1:

Fix two long-standing bugs that allow malicious SQL statements to crash the process that is running SQLite. These bugs were announced by a third-party approximately 24 hours after the 3.32.0 release but are not specific to the 3.32.0 release.

Other minor compiler-warning fixes and whatnot.

sqlite3: updated to 3.32.0

SQLite Release 3.32.0:

Added support for approximate ANALYZE using the PRAGMA analysis_limit command.
Added the bytecode virtual table.
Add the checksum VFS shim to the set of run-time loadable extensions included in the source tree.
Added the iif() SQL function.
INSERT and UPDATE statements now always apply column affinity before computing CHECK constraints. This bug fix could, in theory, cause problems for legacy databases with unorthodox CHECK constraints the require the input type for an INSERT is different from the declared column type. See ticket 86ba67afafded936 for more information.
Added the sqlite3_create_filename(), sqlite3_free_filename(), and sqlite3_database_file_object() interfaces to better support of VFS shim implementations.
Increase the default upper bound on the number of parameters from 999 to 32766.
Added code for the UINT collating sequence as an optional loadable extension.
Enhancements to the CLI:
Add options to the .import command: --csv, --ascii, --skip
The .dump command now accepts multiple LIKE-pattern arguments and outputs the union of all matching tables.
Add the .oom command in debugging builds
Add the --bom option to the .excel, .output, and .once commands.
Enhance the .filectrl command to support the --schema option.
The UINT collating sequence extension is automatically loaded
The ESCAPE clause of a LIKE operator now overrides wildcard characters, so that the behavior now matches what PostgreSQL does.

sqlite3: updated to 3.31.1

SQLite Release 3.31.1:

Revert the data layout for an internal-use-only SQLite data structure. Applications that use SQLite should never reference internal SQLite data structures, but some do anyhow, and a change to one such data structure in 3.30.0 broke a popular and widely-deployed application. Reverting that change in SQLite, at least temporarily, gives developers of misbehaving applications time to fix their code.
Fix a typos in the sqlite3ext.h header file that prevented the sqlite3_stmt_isexplain() and sqlite3_value_frombind() interfaces from being called from run-time loadable extensions.

sqlite3: updated to 3.31.0

SQLite Release 3.31.0:

Add support for generated columns.
Add the sqlite3_hard_heap_limit64() interface and the corresponding PRAGMA hard_heap_limit command.
Enhance the function_list pragma to show the number of arguments on each function, the type of function (scalar, aggregate, window), and the function property flags SQLITE_DETERMINISTIC, SQLITE_DIRECTONLY, SQLITE_INNOCUOUS, and/or SQLITE_SUBTYPE.
Add the aggregated mode feature to the DBSTAT virtual table.
Add the SQLITE_OPEN_NOFOLLOW option to sqlite3_open_v2() that prevents SQLite from opening symbolic links.
Added the "#-N" array notation for JSON function path arguments.
Added the SQLITE_DBCONFIG_TRUSTED_SCHEMA connection setting which is also controllable via the new trusted_schema pragma and at compile-time using the -DSQLITE_TRUSTED_SCHEMA compile-time option.
Added APIs sqlite3_filename_database(), sqlite3_filename_journal(), and sqlite3_filename_wal() which are useful for specialized extensions.
Add the sqlite3_uri_key() interface.
Upgraded the sqlite3_uri_parameter() function so that it works with the rollback journal or WAL filename in addition to the database filename.
Provide the ability to tag application-defined SQL functions with new properties SQLITE_INNOCUOUS or SQLITE_DIRECTONLY.
Add new verbs to sqlite3_vtab_config() so that the xConnect method of virtual tables can declare the virtual table as SQLITE_VTAB_INNOCUOUS or SQLITE_VTAB_DIRECTONLY.
Faster response to sqlite3_interrupt().
Added the uuid.c extension module implementing functions for processing RFC-4122 UUIDs.
The lookaside memory allocator is enhanced to support two separate memory pools with different sized allocations in each pool. This allows more memory allocations to be covered by lookaside while at the same time reducing the heap memory usage to 48KB per connection, down from 120KB.
The legacy_file_format pragma is deactivated. It is now a no-op. In its place, the SQLITE_DBCONFIG_LEGACY_FILE_FORMAT option to sqlite3_db_config() is provided. The legacy_file_format pragma is deactivated because (1) it is rarely useful and (2) it is incompatible with VACUUM in schemas that have tables with both generated columns and descending indexes.

sqlite3: updated to 3.30.0

SQLite Release 3.30.0

Add support for the FILTER clause on aggregate functions.
Add support for the NULLS FIRST and NULLS LAST syntax in ORDER BY clauses.
The index_info and index_xinfo pragmas are enhanced to provide information about the on-disk representation of WITHOUT ROWID tables.
Add the sqlite3_drop_modules() interface, allowing applications to disable automatically loaded virtual tables that they do not need.
Improvements to the .recover dot-command in the CLI so that it recovers more content from corrupt database files.
Enhance the RBU extension to support indexes on expressions.
Change the schema parser so that it will error out if any of the type, name, and tbl_name columns of the sqlite_master table have been corrupted and the database connection is not in writable_schema mode.
The PRAGMA function_list, PRAGMA module_list, and PRAGMA pragma_list commands are now enabled in all builds by default. Disable them using -DSQLITE_OMIT_INTROSPECTION_PRAGMAS.
Add the SQLITE_DBCONFIG_ENABLE_VIEW option for sqlite3_db_config().
Added the TCL Interface config method in order to be able to disable SQLITE_DBCONFIG_ENABLE_VIEW as well as control other sqlite3_db_config() options from TCL.
Added the SQLITE_DIRECTONLY flag for application-defined SQL functions to prevent those functions from being used inside triggers and views.
The legacy SQLITE_ENABLE_STAT3 compile-time option is now a no-op.

sqlite3: updated to 3.29.0

SQLite Release 3.29.0:
Added the SQLITE_DBCONFIG_DQS_DML and SQLITE_DBCONFIG_DQS_DDL actions to sqlite3_db_config() for activating and deactivating the double-quoted string literal misfeature. Both default to "on" for legacy compatibility, but developers are encouraged to turn them "off", perhaps using the -DSQLITE_DQS=0 compile-time option.
-DSQLITE_DQS=0 is now a recommended compile-time option.

Improvements to the query planner:
Improved optimization of AND and OR operators when one or the other operand is a constant.
Enhancements to the LIKE optimization for cases when the left-hand side column has numeric affinity.
Added the "sqlite_dbdata" virtual table for extracting raw low-level content from an SQLite database, even a database that is corrupt.

Enhancements to the CLI:
Add the ".recover" command which tries to recover as much content as possible from a corrupt database file.
Add the ".filectrl" command useful for testing.
Add the long-standing ".testctrl" command to the ".help" menu.
Added the ".dbconfig" command

sqlite3: updated to 3.28.0

SQLite Release 3.28.0:

Enhanced window functions:
Add support the EXCLUDE clause.
Add support for window chaining.
Add support for GROUPS frames.
Add support for "<expr> PRECEDING" and "<expr> FOLLOWING" boundaries in RANGE frames.
Added the new sqlite3_stmt_isexplain(S) interface for determining whether or not a prepared statement is an EXPLAIN.
Enhanced VACUUM INTO so that it works for read-only databases.
New query optimizations:
Enable the LIKE optimization for cases when the ESCAPE keyword is present and PRAGMA case_sensitive_like is on.
In queries that are driven by a partial index, avoid unnecessary tests of the constraint named in the WHERE clause of the partial index, since we know that constraint must always be true.
Enhancements to the TCL Interface:
Added the -returntype option to the function method.
Added the new bind_fallback method.
Enhancements to the CLI:
Added support for bound parameters and the .parameter command.
Fix the readfile() function so that it returns an empty BLOB rather than throwing an out-of-memory error when reading an empty file.
Fix the writefile() function so that when it creates new directories along the path of a new file, it gives them umask permissions rather than the same permissions as the file.
Change --update option in the .archive command so that it skips files that are already in the archive and are unchanged. Add the new --insert option that works like --update used to work.
Added the fossildelta.c extension that can create, apply, and deconstruct the Fossil DVCS file delta format that is used by the RBU extension.
Added the SQLITE_DBCONFIG_WRITABLE_SCHEMA verb for the sqlite3_db_config() interface, that does the same work as PRAGMA writable_schema without using the SQL parser.
Added the sqlite3_value_frombind() API for determining if the argument to an SQL function is from a bound parameter.
Security and compatibilities enhancements to fts3_tokenizer():
The fts3_tokenizer() function always returns NULL unless either the legacy application-defined FTS3 tokenizers interface are enabled using the sqlite3_db_config(SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER) setting, or unless the first argument to fts3_tokenizer() is a bound parameter.
The two-argument version of fts3_tokenizer() accepts a pointer to the tokenizer method object even without the sqlite3_db_config(SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER) setting if the second argument is a bound parameter
Improved robustness against corrupt database files.
Miscellaneous performance enhancements

sqlite3: updated to 3.27.1

SQLite Release 3.27.1:
Fix a bug in the query optimizer: an adverse interaction between the OR optimization and the optimization that tries to use values read directly from an expression index instead of recomputing the expression.

Changes carried forward from version 3.27.0:
Added the VACUUM INTO command
Issue an SQLITE_WARNING message on the error log if a double-quoted string literal is used.
The sqlite3_normalized_sql() interface works on any prepared statement created using sqlite3_prepare_v2() or sqlite3_prepare_v3(). It is no longer necessary to use sqlite3_prepare_v3() with SQLITE_PREPARE_NORMALIZE in order to use sqlite3_normalized_sql().
Added the remove_diacritics=2 option to FTS3 and FTS5.
Added the SQLITE_PREPARE_NO_VTAB option to sqlite3_prepare_v3(). Use that option to prevent circular references to shadow tables from causing resource leaks.
Enhancements to the sqlite3_deserialize() interface:
Add the SQLITE_FCNTL_SIZE_LIMIT file-control for setting an upper bound on the size of the in-memory database created by sqlite3_deserialize. The default upper bound is 1GiB, or whatever alternative value is specified by sqlite3_config(SQLITE_CONFIG_MEMDB_MAXSIZE) and/or SQLITE_MEMDB_DEFAULT_MAXSIZE.
Honor the SQLITE_DESERIALIZE_READONLY flag, which was previously described in the documentation, but was previously a no-op.
Enhance the "deserialize" command of the TCL Interface to give it new "--maxsize N" and "--readonly BOOLEAN" options.
Enhancements to the CLI, mostly to support testing and debugging of the SQLite library itself:
Add support for ".open --hexdb". The "dbtotxt" utility program used to generate the text for the "hexdb" is added to the source tree.
Add support for the "--maxsize N" option on ".open --deserialize".
Add the "--memtrace" command-line option, to show all memory allocations and deallocations.
Add the ".eqp trace" option on builds with SQLITE_DEBUG, to enable bytecode program listing with indentation and PRAGMA vdbe_trace all in one step.
Add the ".progress" command for accessing the sqlite3_progress_handler() interface.
Add the "--async" option to the ".backup" command.
Add options "--expanded", "--normalized", "--plain", "--profile", "--row", "--stmt", and "--close" to the ".trace" command.
Increased robustness against malicious SQL that is run against a maliciously corrupted database.

Bug fixes:
Do not use a partial index to do a table scan on an IN operator.
Fix the query flattener so that it works on queries that contain subqueries that use window functions.
Ensure that ALTER TABLE modifies table and column names embedded in WITH clauses that are part of views and triggers.
Fix a parser bug that prevented the use of parentheses around table-valued functions.
Fix a problem with the OR optimization on indexes on expressions.
Fix a problem with the LEFT JOIN strength reduction optimization in which the optimization was being applied inappropriately due to an IS NOT NULL operator.
Fix the REPLACE command so that it is no longer able to sneak a NULL value into a NOT NULL column even if the NOT NULL column has a default value of NULL.
Fix a problem with the use of window functions used within correlated subqueries.
Fix the ALTER TABLE RENAME COLUMN command so that it works for tables that have redundant UNIQUE constraints.
Fix a bug that caused zeroblob values to be truncated when inserted into a table that uses an expression index.

sqlite3: updated to 3.26.0

SQLite Release 3.26.0:

Optimization: When doing an UPDATE on a table with indexes on expressions, do not update the expression indexes if they do not refer to any of the columns of the table being updated.
Allow the xBestIndex() method of virtual table implementations to return SQLITE_CONSTRAINT to indicate that the proposed query plan is unusable and should not be given further consideration.
Added the SQLITE_DBCONFIG_DEFENSIVE option which disables the ability to create corrupt database files using ordinary SQL.
Added support for read-only shadow tables when the SQLITE_DBCONFIG_DEFENSIVE option is enabled.
Added the PRAGMA legacy_alter_table command, which if enabled causes the ALTER TABLE command to behave like older version of SQLite (prior to version 3.25.0) for compatibility.
Added PRAGMA table_xinfo that works just like PRAGMA table_info except that it also shows hidden columns in virtual tables.
Added the explain virtual table as a run-time loadable extension.
Add a limit counter to the query planner to prevent excessive sqlite3_prepare() times for certain pathological SQL inputs.
Added support for the sqlite3_normalized_sql() interface, when compiling with SQLITE_ENABLE_NORMALIZE.
Enhanced triggers so that they can use table-valued functions that exist in schemas other than the schema where the trigger is defined.
Enhancements to the CLI:
- Improvements to the ".help" command.
- The SQLITE_HISTORY environment variable, if it exists, specifies the name of the command-line editing history file
- The --deserialize option associated with opening a new database cause the database file to be read into memory and accessed using the sqlite3_deserialize() API. This simplifies running tests on a database without modifying the file on disk.
Enhancements to the geopoly extension:
- Aways stores polygons using the binary format, which is faster and uses less space.
- Added the geopoly_regular() function.
- Added the geopoly_ccw() function.
Enhancements to the session extension:
- Added the sqlite3changeset_start_v2() interface and the SQLITE_CHANGESETSTART_INVERT flag.
- Added the changesetfuzz.c test-case generator utility.

sqlite3: updated to 3.25.2

SQLite Release 3.25.2:
Add the PRAGMA legacy_alter_table=ON command that causes the "ALTER TABLE RENAME" command to behave as it did in SQLite versions 3.24.0 and earlier: references to the renamed table inside the bodies of triggers and views are not updated. This new pragma provides a compatibility work around for older programs that expected the older, wonky behavior of ALTER TABLE RENAME.
Fix a problem with the new window functions implementation that caused a malfunction when complicated expressions involving window functions were used inside of a view.
Fixes for various other compiler warnings and minor problems associated with obscure configurations.

sqlite3: updated to 3.25.1

SQLite Release 3.25.1:

Extra sanity checking added to ALTER TABLE in the 3.25.0 release sometimes raises a false-positive when the table being modified has a trigger that updates a virtual table. The false-positive caused the ALTER TABLE to rollback, thus leaving the schema unchanged.
The fix in the 3.25.0 release for the endless-loop in the byte-code associated with the ORDER BY LIMIT optimization did not work for some queries involving window functions. An additional correction is required.

sqlite3: updated to 3.25.0

SQLite Release 3.25.0:

Add support for window functions
Enhancements the ALTER TABLE command:
- Add support for renaming columns within a table using ALTER TABLE table RENAME COLUMN oldname TO newname.
- Fix table rename feature so that it also updates references to the renamed table in triggers and views.
Query optimizer improvements:
- Avoid unnecessary loads of columns in an aggregate query that are not within an aggregate function and that are not part of the GROUP BY clause.
- The IN-early-out optimization: When doing a look-up on a multi-column index and an IN operator is used on a column other than the left-most column, then if no rows match against the first IN value, check to make sure there exist rows that match the columns to the right before continuing with the next IN value.
- Use the transitive property to try to propagate constant values within the WHERE clause. For example, convert "a=99 AND b=a" into "a=99 AND b=99".
Use a separate mutex on every inode in the unix VFS, rather than a single mutex shared among them all, for slightly better concurrency in multi-threaded environments.
Enhance the PRAGMA integrity_check command for improved detection of problems on the page freelist.
Output infinity as 1e999 in the ".dump" command of the command-line shell.
Added the SQLITE_FCNTL_DATA_VERSION file-control.
Added the Geopoly module

Bug fixes:
The ORDER BY LIMIT optimization might have caused an infinite loop in the byte code of the prepared statement under very obscure circumstances, due to a confluence of minor defects in the query optimizer.
On an UPSERT when the order of constraint checks is rearranged, ensure that the affinity transformations on the inserted content occur before any of the constraint checks.
Avoid using a prepared statement for ".stats on" command of the CLI after it has been closed by the ".eqp full" logicc.
The LIKE optimization was generating incorrect byte-code and hence getting the wrong answer if the left-hand operand has numeric affinity and the right-hand-side pattern is '/%' or if the pattern begins with the ESCAPE character.

sqlite3: updated to 3.24.0

SQLite Release 3.24.0:
Add support for PostgreSQL-style UPSERT.
Add support for auxiliary columns in r-tree tables.
Add C-language APIs for discovering SQL keywords used by SQLite: sqlite3_keyword_count(), sqlite3_keyword_name(), and sqlite3_keyword_check().
Add C-language APIs for dynamic strings based on the sqlite3_str object.
Enhance ALTER TABLE so that it recognizes "true" and "false" as valid arguments to DEFAULT.
Add the sorter-reference optimization as a compile-time option. Only available if compiled with SQLITE_ENABLE_SORTER_REFERENCES.
Improve the format of the EXPLAIN QUERY PLAN raw output, so that it gives better information about the query plan and about the relationships between the various components of the plan.
Added the SQLITE_DBCONFIG_RESET_DATABASE option to the sqlite3_db_config() API.
CLI Enhancements:

Automatically intercepts the raw EXPLAIN QUERY PLAN output and reformats it into an ASCII-art graph.
Lines that begin with "#" and that are not in the middle of an SQL statement are interpreted as comments.
Added the --append option to the ".backup" command.
Added the ".dbconfig" command.

UPDATE avoids unnecessary low-level disk writes when the contents of the database file do not actually change. For example, "UPDATE t1 SET x=25 WHERE y=?" generates no extra disk I/O if the value in column x is already 25. Similarly, when doing UPDATE on records that span multiple pages, only the subset of pages that actually change are written to disk. This is a low-level performance optimization only and does not affect the behavior of TRIGGERs or other higher level SQL structures.
Queries that use ORDER BY and LIMIT now try to avoid computing rows that cannot possibly come in under the LIMIT. This can greatly improve performance of ORDER BY LIMIT queries, especially when the LIMIT is small relative to the number of unrestricted output rows.
The OR optimization is allowed to proceed even if the OR expression has also been converted into an IN expression. Uses of the OR optimization are now also more clearly shown in the EXPLAIN QUERY PLAN output.
The query planner is more aggressive about using automatic indexes for views and subqueries for which it is not possible to create a persistent index.
Make use of the one-pass UPDATE and DELETE query plans in the R-Tree extension where appropriate.
Performance improvements in the LEMON-generated parser.
Bug fixes:

For the right-hand table of a LEFT JOIN, compute the values of expressions directly rather than loading precomputed values out of an expression index as the expression index might not contain the correct value.
Do not attempt to use terms from the WHERE clause to enable indexed lookup of the right-hand table of a LEFT JOIN.
Fix a memory leak that can occur following a failure to open error in the CSV virtual table
Fix a long-standing problem wherein a corrupt schema on the sqlite_sequence table used by AUTOINCREMENT can lead to a crash.
Fix the json_each() function so that it returns valid results on its "fullkey" column when the input is a simple value rather than an array or object.

sqlite3: updated to 3.23.0

SQLite Release 3.23.0:

Add the sqlite3_serialize() and sqlite3_deserialize() interfaces when the SQLITE_ENABLE_DESERIALIZE compile-time option is used.
Recognize TRUE and FALSE as constants. (For compatibility, if there exist columns named "true" or "false", then the identifiers refer to the columns rather than Boolean constants.)
Support operators IS TRUE, IS FALSE, IS NOT TRUE, and IS NOT FALSE.
Added the SQLITE_DBSTATUS_CACHE_SPILL option to sqlite3_db_status() for reporting the number of cache spills that have occurred.
The "alternate-form-2" flag ("!") on the built-in printf implementation now causes string substitutions to measure the width and precision in characters instead of bytes.
If the xColumn method in a virtual table implementation returns an error message using sqlite3_result_error() then give that error message preference over internally-generated messages.
Added the -A command-line option to the CLI to make it easier to manage SQLite Archive files.
Add support for INSERT OR REPLACE, INSERT OR IGNORE, and UPDATE OR REPLACE in the Zipfile virtual table.
Enhance the sqlite3changeset_apply() interface so that it is hardened against attacks from deliberately corrupted changeset objects.
Added the sqlite3_normalize() extension function.

Query optimizer enhancements:
Improve the omit-left-join optimization so that it works in cases where the right-hand table is UNIQUE but not necessarily NOT NULL.
Improve the push-down optimization so that it works for many LEFT JOINs.
Add the LEFT JOIN strength reduction optimization that converts a LEFT JOIN into an ordinary JOIN if there exist terms in the WHERE clause that would prevent the extra all-NULL row of the LEFT JOIN from appearing in the output set.
Avoid unnecessary writes to the sqlite_sequence table when an AUTOINCREMENT table is updated with an rowid that is less than the maximum.

Bug fixes:
Fix the parser to accept valid row value syntax.
Fix the query planner so that it takes into account dependencies in the arguments to table-valued functions in subexpressions in the WHERE clause.
Fix incorrect result with complex OR-connected WHERE and STAT4.
Fix potential corruption in indexes on expressions due to automatic datatype conversions.
Assertion fault in FTS4.
Incorrect result on the less-than operator in row values.
Always interpret non-zero floating-point values as TRUE, even if the integer part is zero.
Fix an issue in the fsdir(PATH) table-valued function to the fileio.c extension, that caused a segfault if the fsdir() table was used as the inner table of a join.
Issue an error rather instead of an assertion-fault or null-pointer dereference when the sqlite_master table is corrupted so that the sqlite_sequence table root page is really a btree-index page.
Fix the ANALYZE command so that it computes statistics on tables whose names begin with "sqlite".

Additional fixes for issues detected by OSSFuzz:
Fix a possible infinite loop on VACUUM for corrupt database files.
Disallow parameters in the WITH clause of triggers and views.
Fix a potential memory leak in row value processing.
Improve the performance of the replace() SQL function for cases where there are many substitutions on megabyte-sized strings, in an attempt to avoid OSSFuzz timeouts during testing.
Provide an appropriate error message when the sqlite_master table contains a CREATE TABLE AS statement. Formerly this caused either an assertion fault or null pointer dereference. Problem found by OSSFuzz on the GDAL project.
Incorrect assert() statement removed.
Fix a problem with using the LIKE optimization on an INTEGER PRIMARY KEY.

sqlite3: updated to 3.22.0

Release 3.22.0:
The output of sqlite3_trace_v2() now shows each individual SQL statement run within a trigger.
Add the ability to read from WAL mode databases even if the application lacks write permission on the database and its containing directory, as long as the -shm and -wal files exist in that directory.
Added the rtreecheck() scalar SQL function to the R-Tree extension.
Added the sqlite3_vtab_nochange() and sqlite3_value_nochange() interfaces to help virtual table implementations optimize UPDATE operations.
Added the sqlite3_vtab_collation() interface.
Added support for the "^" initial token syntax in FTS5.
New extensions:
The Zipfile virtual table can read and write a ZIP Archive.
Added the fsdir(PATH) table-valued function to the fileio.c extension, for listing the files in a directory.
The sqlite_btreeinfo eponymous virtual table for introspecting and estimating the sizes of the btrees in a database.
The Append VFS is a VFS shim that allows an SQLite database to be appended to some other file. This allows (for example) a database to be appended to an executable that then opens and reads the database.
Query planner enhancements:
The optimization that uses an index to quickly compute an aggregate min() or max() is extended to work with indexes on expressions.
The decision of whether to implement a FROM-clause subquery as a co-routine or using query flattening now considers whether the result set of the outer query is "complex" (if it contains functions or expression subqueries). A complex result set biases the decision toward the use of co-routines.
The planner avoids query plans that use indexes with unknown collating functions.
The planner omits unused LEFT JOINs even if they are not the right-most joins of a query.
Other performance optimizations:
A smaller and faster implementation of text to floating-point conversion subroutine: sqlite3AtoF().
The Lemon parser generator creates a faster parser.
Use the strcspn() C-library routine to speed up the LIKE and GLOB operators.
Improvements to the command-line shell:
The ".schema" command shows the structure of virtual tables.
Added support for reading and writing SQL Archive files using the .archive command.
Added the experimental .expert command
Added the ".eqp trigger" variant of the ".eqp" command
Enhance the ".lint fkey-indexes" command so that it works with WITHOUT ROWID tables.
If the filename argument to the shell is a ZIP archive rather than an SQLite database, then the shell automatically opens that ZIP archive using the Zipfile virtual table.
Added the edit() SQL function.
Added the .excel command to simplify exporting database content to a spreadsheet.
Databases are opened using Append VFS when the --append flag is used on the command line or with the .open command.
Enhance the SQLITE_ENABLE_UPDATE_DELETE_LIMIT compile-time option so that it works for WITHOUT ROWID tables.
Provide the sqlite_offset(X) SQL function that returns the byte offset into the database file to the beginning of the record holding value X, when compiling with -DSQLITE_ENABLE_OFFSET_SQL_FUNC.

sqlite3: updated to 3.21.0

Release 3.21.0:

Take advantage of the atomic-write capabilities in the F2FS filesystem when available, for greatly reduced transaction overhead. This currently requires the SQLITE_ENABLE_BATCH_ATOMIC_WRITE compile-time option.
Allow ATTACH and DETACH commands to work inside of a transaction.
Allow WITHOUT ROWID virtual tables to be writable if the PRIMARY KEY contains exactly one column.
The "fsync()" that occurs after the header is written in a WAL reset now uses the sync settings for checkpoints. This means it will use a "fullfsync" on macs if PRAGMA checkpoint_fullfsync set on.
The sqlite3_sourceid() function tries to detect if the source code has been modified from what is checked into version control and if there are modifications, the last four characters of the version hash are shown as "alt1" or "alt2". The objective is to detect accidental and/or careless edits. A forger can subvert this feature.
Improved de-quoting of column names for CREATE TABLE AS statements with an aggregate query on the right-hand side.
Fewer "stat()" system calls issued by the unix VFS.
Enhanced the LIKE optimization so that it works with an ESCAPE clause.
Enhanced PRAGMA integrity_check and PRAGMA quick_check to detect obscure row corruption that they were formerly missing. Also update both pragmas so that they return error text rather than SQLITE_CORRUPT when encountering corruption in records.
The query planner now prefers to implement FROM-clause subqueries using co-routines rather using the query flattener optimization. Support for the use of co-routines for subqueries may no longer be disabled.
Pass information about !=, IS, IS NOT, NOT NULL, and IS NULL constraints into the xBestIndex method of virtual tables.
Enhanced the CSV virtual table so that it accepts the last row of input if the final new-line character is missing.
Remove the rarely-used "scratch" memory allocator. Replace it with the SQLITE_CONFIG_SMALL_MALLOC configuration setting that gives SQLite a hint that large memory allocations should be avoided when possible.
Added the swarm virtual table to the existing union virtual table extension.
Added the sqlite_dbpage virtual table for providing direct access to pages of the database file. The source code is built into the amalgamation and is activated using the -DSQLITE_ENABLE_DBPAGE_VTAB compile-time option.
Add a new type of fts5vocab virtual table - "instance" - that provides direct access to an FTS5 full-text index at the lowest possible level.
Remove a call to rand_s() in the Windows VFS since it was causing problems in Firefox on some older laptops.
The src/shell.c source code to the command-line shell is no longer under version control. That file is now generated as part of the build process.
Miscellaneous microoptimizations reduce CPU usage by about 2.1%.

SQLite Release 3.19.0
The SQLITE_READ authorizer callback is invoked once with a column name that is an empty string for every table referenced in a query from which no columns are extracted.
When using an index on an expression, try to use expression values already available in the index, rather than loading the original columns and recomputing the expression.
Enhance the flattening optimization so that it is able to flatten views on the right-hand side of a LEFT JOIN.
Use replace() instead of char() for escaping newline and carriage-return characters embedded in strings in the .dump output from the command-line shell.
Avoid unnecessary foreign key processing in UPDATE statements that do not touch the columns that are constrained by the foreign keys.
On a DISTINCT query that uses an index, try to skip ahead to the next distinct entry using the index rather than stepping through rows, when an appropriate index is available.
Avoid unnecessary invalidation of sqlite3_blob handles when making changes to unrelated tables.
Transfer any terms of the HAVING clause that use only columns mentioned in the GROUP BY clause over to the WHERE clause for faster processing.
Reuse the same materialization of a VIEW if that VIEW appears more than once in the same query.
Enhance PRAGMA integrity_check so that it identifies tables that have two or more rows with the same rowid.
Enhance the FTS5 query syntax so that column filters may be applied to arbitrary expressions.
Enhance the json_extract() function to cache and reuse parses of JSON input text.
Added the anycollseq.c loadable extension that allows a generic SQLite database connection to read a schema that contains unknown and/or application-specific collating sequences.

Bug Fixes:
Fix a problem in REPLACE that can result in a corrupt database containing two or more rows with the same rowid.
Fix a problem in PRAGMA integrity_check that was causing a subsequent VACUUM to behave suboptimally.
Fix the PRAGMA foreign_key_check command so that it works correctly with foreign keys on WITHOUT ROWID tables.
Disallow leading zeros in numeric constants in JSON.
Disallow control characters inside of strings in JSON.
Limit the depth of recursion for JSON objects and arrays in order to avoid excess stack usage in the recursive descent parser.

SQLite Release 3.17.0 On 2017-02-13
* Approximately 25% better performance from the R-Tree extension.
* Uses compiler built-ins (ex: __builtin_bswap32() or _byteswap_ulong()) for byteswapping when available.
* Uses the sqlite3_blob key/value access object instead of SQL for pulling content out of R-Tree nodes
* Other miscellaneous enhancements such as loop unrolling.
* Add the SQLITE_DEFAULT_LOOKASIDE compile-time option.
* Increase the default lookaside size from 512,125 to 1200,100 as this provides better performance while only adding 56KB of extra memory per connection. Memory-sensitive applications can restore the old default at compile-time, start-time, or run-time.
* Use compiler built-ins __builtin_sub_overflow(), __builtin_add_overflow(), and __builtin_mul_overflow() when available. (All compiler built-ins can be omitted with the SQLITE_DISABLE_INTRINSIC compile-time option.)
* Added the SQLITE_ENABLE_NULL_TRIM compile-time option, which can result in significantly smaller database files for some applications, at the risk of being incompatible with older versions of SQLite.
* Change SQLITE_DEFAULT_PCACHE_INITSZ from 100 to 20, for improved performance.
* Added the SQLITE_UINT64_TYPE compile-time option as an analog to SQLITE_INT64_TYPE.
* Perform some UPDATE operations in a single pass instead of in two passes.
* Enhance the session extension to support WITHOUT ROWID tables.
* Fixed performance problems and potential stack overflows when creating views from multi-row VALUES clauses with hundreds of thousands of rows.
* Added the sha1.c extension.
* In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl".
* Enhance the SQLITE_DIRECT_OVERFLOW_READ option so that it works in WAL mode as long as the pages being read are not in the WAL file.
* Enhance the LEMON parser generator so that it can store the parser object as a stack variable rather than allocating space from the heap and make use of that enhancement in the amalgamation.
* Other performance improvements. Uses about 6.5% fewer CPU cycles.

Bug Fixes:
* Throw an error if the ON clause of a LEFT JOIN references tables to the right of the ON clause. This is the same behavior as PostgreSQL. Formerly, SQLite silently converted the LEFT JOIN into an INNER JOIN.
* Use the correct affinity for columns of automatic indexes.
* Ensure that the sqlite3_blob_reopen() interface can correctly handle short rows.

Changes 3.16.2:
Fix the REPLACE statement for WITHOUT ROWID tables that lack secondary indexes so that it works correctly with triggers and foreign keys. This was a new bug caused by performance optimizations added in version 3.16.0. Ticket 30027b613b4
Fix the sqlite3_value_text() interface so that it correctly translates content generated by zeroblob() into a string of all 0x00 characters. This is a long-standing issue discovered after the 3.16.1 release by OSS-Fuzz
Fix the bytecode generator to deal with a subquery in the FROM clause that is itself a UNION ALL where one side of the UNION ALL is a view that contains an ORDER BY. This is a long-standing issue that was discovered after the release of 3.16.1. See ticket 190c2507.
Adjust the sqlite3_column_count() API so it more often returns the same values for PRAGMA statements as it did in prior releases, to minimize disruption to applications that might be using that interface in unexpected ways.

SQLite Release 3.16.0 On 2017-01-02

Uses 9% fewer CPU cycles. (See the CPU performance measurement report for details on how the this performance increase was computed.)
Added experimental support for PRAGMA functions.
Added the SQLITE_DBCONFIG_NO_CKPT_ON_CLOSE option to sqlite3_db_config().
Enhance the date and time functions so that the 'unixepoch' modifier works for the full span of supported dates.
Changed the default configuration of the lookaside memory allocator from 500 slots of 128 bytes each into 125 slots of 512 bytes each.
Enhanced "WHERE x NOT NULL" partial indexes so that they are usable if the "x" column appears in a LIKE or GLOB operator.
Enhanced sqlite3_interrupt() so that it interrupts checkpoint operations that are in process.
Enhanced the LIKE and GLOB matching algorithm to be faster for cases when the pattern contains multiple wildcards.
Added the SQLITE_FCNTL_WIN32_GET_HANDLE file control opcode.
Added ".mode quote" to the command-line shell.
Added ".lint fkey-indexes" to the command-line shell.
Added the .imposter dot-command to the command-line shell.
Added the remember(V,PTR) SQL function as a loadable extension.
Rename the SQLITE_OMIT_BUILTIN_TEST compile-time option to SQLITE_UNTESTABLE to better reflect the implications of using it.

Bug Fixes:
Fix a long-standing bug in the query planner that caused incorrect results on a LEFT JOIN where the left-hand table is a subquery and the join constraint is a bare column name coming from the left-hand subquery. Ticket 2df0107b.
Correctly handle the integer literal -0x8000000000000000 in the query planner.

The multiply operator now correctly detects 64-bit integer overflow and promotes to floating point in all corner-cases.
Correct handling of columns with redundant unique indexes when those columns are used on the LHS of an IN operator.
Skip NULL entries on range queries in indexes on expressions.
Ensure that the AUTOINCREMENT counters in the sqlite_sequence table are initialized doing "Xfer Optimization" on "INSERT ... SELECT" statements.

Improved the query planner so that the OR optimization can be used on virtual tables even if one or more of the disjuncts use the LIKE, GLOB, REGEXP, MATCH operators.
Added the CSV virtual table for reading RFC 4180 formatted comma-separated value files.
Added the carray() table-valued function extension.
Enabled persistent loadable extensions using the new SQLITE_OK_LOAD_PERMANENTLY return code from the extension entry point.
Added the SQLITE_DBSTATUS_CACHE_USED_SHARED option to sqlite3_db_status().
Add the vfsstat.c loadable extension - a VFS shim that measures I/O together with an eponymous virtual table that provides access to the measurements.
Improved algorithm for running queries with both an ORDER BY and a LIMIT where only the inner-most loop naturally generates rows in the correct order.
Enhancements to Lemon parser generator, so that it generates a faster parser.
The PRAGMA compile_options command now attempts to show the version number of the compiler that generated the library.
Enhance PRAGMA table_info so that it provides information about eponymous virtual tables.
Added the "win32-none" VFS, analogous to the "unix-none" VFS, that works like the default "win32" VFS except that it ignores all file locks.
The query planner uses a full scan of a partial index instead of a full scan of the main table, in cases where that makes sense.
Allow table-valued functions to appear on the right-hand side of an IN operator.
Created the dbhash.exe command-line utility.
Added two new C-language interfaces: sqlite3_expanded_sql() and sqlite3_trace_v2(). These new interfaces subsume the functions of sqlite3_trace() and sqlite3_profile() which are now deprecated.
Added the json_quote() SQL function to the json1 extension.
Disable the authorizer callback while reparsing the schema.
Added the SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option and turned that option on by default when building the command-line shell.

Bug Fixes:
Fix the ALTER TABLE command so that it does not corrupt descending indexes when adding a column to a legacy file format database.
Fix a NULL-pointer dereference/crash that could occurs when a transitive WHERE clause references a non-existent collating sequence.
Improved the cost estimation for an index scan which includes a WHERE clause that can be partially or fully evaluated using columns in the index and without having to do a table lookup. This fixes a performance regression that occurred for some obscure queries following the ORDER BY LIMIT optimization introduced in version 3.12.0.

Release 3.13.0:

Postpone I/O associated with TEMP files for as long as possible, with the hope that the I/O can ultimately be avoided completely.
Merged the session extension into trunk.
Added the ".auth ON|OFF" command to the command-line shell.
Added the "--indent" option to the ".schema" and ".fullschema" commands of the command-line shell, to turn on pretty-printing.
Added the ".eqp full" option to the command-line shell, that does both EXPLAIN and EXPLAIN QUERY PLAN on each statement that is evaluated.
Improved unicode filename handling in the command-line shell on Windows.
Improved resistance against goofy query planner decisions caused by incomplete or incorrect modifications to the sqlite_stat1 table by the application.
Added the sqlite3_db_config(db,SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION) interface which allows the sqlite3_load_extension() C-API to be enabled while keeping the load_extension() SQL function disabled for security.
Change the temporary directory search algorithm on Unix to allow directories with write and execute permission, but without read permission, to serve as temporary directories. Apply this same standard to the "." fallback directory.

Bug Fixes:
Fix a problem with the multi-row one-pass DELETE optimization that was causing it to compute incorrect answers with a self-referential subquery in the WHERE clause. Fix for ticket dc6ebeda9396087
Fix a possible segfault with DELETE when table is a rowid table with an INTEGER PRIMARY KEY and the WHERE clause contains a OR and the table has one or more indexes that are able to trigger the OR optimization, but none of the indexes reference any table columns other than the INTEGER PRIMARY KEY. Ticket 16c9801ceba49.
When checking for the WHERE-clause push-down optimization, verify that all terms of the compound inner SELECT are non-aggregate, not just the last term. Fix for ticket f7f8c97e97597.
Fix a locking race condition in Windows that can occur when two or more processes attempt to recover the same hot journal at the same time.

Release 3.12.0

Potentially Disruptive Change:
The SQLITE_DEFAULT_PAGE_SIZE is increased from 1024 to 4096. The SQLITE_DEFAULT_CACHE_SIZE is changed from 2000 to -2000 so the same amount of cache memory is used by default. See the application note on the version 3.12.0 page size change for further information.

Performance enhancements:
Enhancements to the Lemon parser generator so that it creates a smaller and faster SQL parser.
Only create master journal files if two or more attached databases are all modified, do not have PRAGMA synchronous set to OFF, and do not have the journal_mode set to OFF, MEMORY, or WAL.
Only create statement journal files when their size exceeds a threshold. Otherwise the journal is held in memory and no I/O occurs. The threshold can be configured at compile-time using SQLITE_STMTJRNL_SPILL or at start-time using sqlite3_config(SQLITE_CONFIG_STMTJRNL_SPILL).
The query planner is able to optimize IN operators on virtual tables even if the xBestIndex method does not set the sqlite3_index_constraint_usage.omit flag of the virtual table column to the left of the IN operator.
The query planner now does a better job of optimizing virtual table accesses in a 3-way or higher join where constraints on the virtual table are split across two or more other tables of the join.
More efficient handling of application-defined SQL functions, especially in cases where the application defines hundreds or thousands of custom functions.
The query planner considers the LIMIT clause when estimating the cost of ORDER BY.
The configure script (on unix) automatically detects pread() and pwrite() and sets compile-time options to use those OS interfaces if they are available.
Reduce the amount of memory needed to hold the schema.
Other miscellaneous micro-optimizations for improved performance and reduced memory usage.

New Features:
Added the SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER option to sqlite3_db_config() which allows the two-argument version of the fts3_tokenizer() SQL function to be enabled or disabled at run-time.
Added the sqlite3rbu_bp_progress() interface to the RBU extension.
The PRAGMA defer_foreign_keys=ON statement now also disables RESTRICT actions on foreign key.
Added the sqlite3_system_errno() interface.
Added the SQLITE_DEFAULT_SYNCHRONOUS and SQLITE_DEFAULT_WAL_SYNCHRONOUS compile-time options. The SQLITE_DEFAULT_SYNCHRONOUS compile-time option replaces the SQLITE_EXTRA_DURABLE option, which is no longer supported.
Enhanced the ".stats" command in the command-line shell to show more information about I/O performance obtained from /proc, when available.

Bug fixes:
Make sure the sqlite3_set_auxdata() values from multiple triggers within a single statement do not interfere with one another.
Fix the code generator for expressions of the form "x IN (SELECT...)" where the SELECT statement on the RHS is a correlated subquery.
Fix a harmless TSAN warning associated with the sqlite3_db_readonly() interface.

Changes 3.11.0:

General improvements:

Enhanced WAL mode so that it works efficiently with transactions that are larger than the cache_size.
Added the FTS5 detail option.
Added the "EXTRA" option to PRAGMA synchronous that does a sync of the containing directory when a rollback journal is unlinked in DELETE mode, for better durability. The SQLITE_EXTRA_DURABLE compile-time option enables PRAGMA synchronous=EXTRA by default.
Enhanced the query planner so that it is able to use a covering index as part of the OR optimization.
Avoid recomputing NOT NULL and CHECK constraints on unchanged columns in UPDATE statement.
Many micro-optimizations, resulting in a library that is faster than the previous release.
Enhancements to the command-line shell:

By default, the shell is now in "auto-explain" mode. The output of EXPLAIN commands is automatically formatted.
Added the ".vfslist" dot-command.
The SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option is now turned on by default in the standard builds.

Enhancements to the TCL Interface:

If a database connection is opened with the "-uri 1" option, then URI filenames are honored by the "backup" and "restore" commands.
Added the "-sourceid" option to the "sqlite3" command.
Makefile improvements:

Improved pthreads detection in configure scripts.
Add the ability to do MSVC Windows builds from the amalgamation tarball.

Bug fixes

Fix an issue with incorrect sharing of VDBE temporary registers between co-routines that could cause incorrect query results in obscure cases. Ticket d06a25c84454a.
Fix a problem in the sqlite3_result_subtype() interface that could cause problems for the json1 extension under obscure circumstances. Fix for ticket f45ac567eaa9f9.
Escape control characters in JSON strings. Fix for ticket ad2559db380abf8.
Reenable the xCurrentTime and xGetLastError methods in the built-in unix VFSes as long as SQLITE_OMIT_DEPRECATED is not defined.

Backwards Compatibility:
Because of continuing security concerns, the two-argument version of of the seldom-used and little-known fts3_tokenizer() function is disabled unless SQLite is compiled with the SQLITE_ENABLE_FTS3_TOKENIZER.

Changes 3.10.0:

General improvements:
Added support for LIKE, GLOB, and REGEXP operators on virtual tables.
Added the colUsed field to sqlite3_index_info for use by the sqlite3_module.xBestIndex method.
Enhance the PRAGMA cache_spill statement to accept a 32-bit integer parameter which is the threshold below which cache spilling is prohibited.
On unix, if a symlink to a database file is opened, then the corresponding journal files are based on the actual filename, not the symlink name.
Added the "--transaction" option to sqldiff.
Added the sqlite3_db_cacheflush() interface.
Added the sqlite3_strlike() interface.
When using memory-mapped I/O map the database file read-only so that stray pointers and/or array overruns in the application cannot accidently modify the database file.
Added the experimental sqlite3_snapshot_get(), sqlite3_snapshot_open(), and sqlite3_snapshot_free() interfaces. These are subject to change or removal in a subsequent release.
Enhance the 'utc' modifier in the date and time functions so that it is a no-op if the date/time is known to already be in UTC. (This is not a compatibility break since the behavior has long been documented as "undefined" in that case.)
Added the json_group_array() and json_group_object() SQL functions in the json extension.
Added the SQLITE_LIKE_DOESNT_MATCH_BLOBS compile-time option.
Many small performance optimizations.

Portability enhancements:
Work around a sign-exension bug in the optimizer of the HP C compiler on HP/UX. (details)

Enhancements to the command-line shell:
Added the ".changes ON|OFF" and ".vfsinfo" dot-commands.
Translate between MBCS and UTF8 when running in cmd.exe on Windows.

Enhancements to makefiles:
Added the --enable-editline and --enable-static-shell options to the various autoconf-generated configure scripts.
Omit all use of "awk" in the makefiles, to make building easier for MSVC users.

Important fixes:
Fix inconsistent integer to floating-point comparison operations that could result in a corrupt index if the index is created on a table column that contains both large integers and floating point values of similar magnitude. Ticket 38a97a87a6.
Fix an infinite-loop in the query planner that could occur on malformed common table expressions.
Various bug fixes in the sqldiff tool.

Changes 3.9.0:
Policy Changes:
* The version numbering conventions for SQLite are revised to use the emerging standard of semantic versioning.

New Features And Enhancements:
* Added the json1 extension module in the source tree, and in the amalgamation. Enable support using the SQLITE_ENABLE_JSON1 compile-time option.
* Added Full Text Search version 5 (FTS5) to the amalgamation, enabled using SQLITE_ENABLE_FTS5. FTS5 will be considered "experimental" (subject to incompatible changes) for at least one more release cycle.
* The CREATE VIEW statement now accepts an optional list of column names following the view name.
* Added support for indexes on expressions.
* Added support for table-valued functions in the FROM clause of a SELECT statement.
* Added support for eponymous virtual tables.
* A VIEW may now reference undefined tables and functions when initially created. Missing tables and functions are reported when the VIEW is used in a query.
* Added the sqlite3_value_subtype() and sqlite3_result_subtype() interfaced (used by the json1 extension).
* The query planner is now able to use partial indexes that contain AND-connected terms in the WHERE clause.
* The sqlite3_analyzer.exe utility is updated to report the depth of each btree and to show the average fanout for indexes and WITHOUT ROWID tables.
* Enhanced the dbstat virtual table so that it can be used as a table-valued function where the argument is the schema to be analyzed.

Other changes:
* The sqlite3_memory_alarm() interface, which has been deprecated and undocumented for 8 years, is changed into a no-op.

Important fixes:
* Fixed a critical bug in the SQLite Encryption Extension that could cause the database to become unreadable and unrecoverable if a VACUUM command changed the size of the encryption nonce.
* Added a memory barrier in the implementation of sqlite3_initialize() to help ensure that it is thread-safe.
* Fix the OR optimization so that it always ignores subplans that do not use an index.
* Do not apply the WHERE-clause pushdown optimization on terms that originate in the ON or USING clause of a LEFT JOIN.

Added the experimental FTS5 extension. Note that this extension is experimental and subject to change in incompatible ways.
Added the sqlite3_value_dup() and sqlite3_value_free() interfaces.
Enhance the spellfix1 extension to support ON CONFLICT clauses.
The IS operator is now able to drive indexes.
Enhance the query planner to permit automatic indexing on FROM-clause subqueries that are implemented by co-routine.
Disallow the use of "rowid" in common table expressions.
Added the PRAGMA cell_size_check command for better and earlier detection of database file corruption.
Added the matchinfo 'b' flag to the matchinfo() function in FTS3.
Improved fuzz-testing of database files, with fixes for problems found.
Add the fuzzcheck test program and automatically run this program using both SQL and database test cases on "make test".
Added the SQLITE_MUTEX_STATIC_VFS1 static mutex and use it in the Windows VFS.
The sqlite3_profile() callback is invoked (by sqlite3_reset() or sqlite3_finalize()) for statements that did not run to completion.
Enhance the page cache so that it can preallocate a block of memory to use for the initial set page cache lines. Set the default preallocation to 100 pages. Yields about a 5% performance increase on common workloads.
Miscellaneous micro-optimizations result in 22.3% more work for the same number of CPU cycles relative to the previous release. SQLite now runs twice as fast as version 3.8.0 and three times as fast as version 3.3.9. (Measured using cachegrind on the speedtest1.c workload on Ubuntu 14.04 x64 with gcc 4.8.2 and -Os. Your performance may vary.)
Added the sqlite3_result_zeroblob64() and sqlite3_bind_zeroblob64() interfaces.

New Features:
* Added the PRAGMA data_version command that can be used to determine if a database file has been modified by another process.
* Added the SQLITE_CHECKPOINT_TRUNCATE option to the sqlite3_wal_checkpoint_v2() interface, with corresponding enhancements to PRAGMA wal_checkpoint.
* Added the sqlite3_stmt_scanstatus() interface, available only when compiled with SQLITE_ENABLE_STMT_SCANSTATUS.
* The sqlite3_table_column_metadata() is enhanced to work correctly on WITHOUT ROWID tables and to check for the existence of a a table if the column name parameter is NULL. The interface is now also included in the build by default, without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option.
* Added the SQLITE_ENABLE_API_ARMOR compile-time option.
* Added the SQLITE_REVERSE_UNORDERED_SELECTS compile-time option.
* Added the SQLITE_SORTER_PMASZ compile-time option and SQLITE_CONFIG_PMASZ start-time option.
* Added the SQLITE_CONFIG_PCACHE_HDRSZ option to sqlite3_config() which makes it easier for applications to determine the appropriate amount of memory for use with SQLITE_CONFIG_PAGECACHE.
* The number of rows in a VALUES clause is no longer limited by SQLITE_LIMIT_COMPOUND_SELECT.
* Added the eval.c loadable extension that implements an eval() SQL function that will recursively evaluate SQL.

Performance Enhancements:
* Reduce the number of memcpy() operations involved in balancing a b-tree, for 3.2% overall performance boost.
* Improvements to cost estimates for the skip-scan optimization.
* The automatic indexing optimization is now capable of generating a partial index if that is appropriate.

Bug fixes:
* Ensure durability following a power loss with "PRAGMA journal_mode=TRUNCATE" by calling fsync() right after truncating the journal file.
* The query planner now recognizes that any column in the right-hand table of a LEFT JOIN can be NULL, even if that column has a NOT NULL constraint. Avoid trying to optimize out NULL tests in those cases.
* Make sure ORDER BY puts rows in ascending order even if the DISTINCT operator is implemented using a descending index.
* Fix data races that might occur under stress when running with many threads in shared cache mode where some of the threads are opening and closing connections.
* Fix obscure crash bugs found by american fuzzy lop.
* Work around a GCC optimizer bug (for gcc 4.2.1 on MacOS 10.7) that caused the R-Tree extension to compute incorrect results when compiled with -O3.

Other changes:
* Disable the use of the strchrnul() C-library routine unless it is specifically enabled using the -DHAVE_STRCHRNULL compile-time option.
* Improvements to the effectiveness and accuracy of the likelihood(), likely(), and unlikely() SQL hint functions.

Changes 3.8.7:

Performance Enhancements:
* Many micro-optimizations result in 20.3% more work for the same number of CPU cycles relative to the previous release. The cumulative performance increase since version 3.8.0 is 61%. (Measured using cachegrind on the speedtest1.c workload on Ubuntu 13.10 x64 with gcc 4.8.1 and -Os. Your performance may vary.)
* The sorter can use auxiliary helper threads to increase real-time response. This feature is off by default and may be enabled using the PRAGMA threads command or the SQLITE_DEFAULT_WORKER_THREADS compile-time option.
* Enhance the skip-scan optimization so that it is able to skip index terms that occur in the middle of the index, not just as the left-hand side of the index.
* Improved optimization of CAST operators.
* Various improvements in how the query planner uses sqlite_stat4 information to estimate plan costs.

New Features:
* Added new interfaces with 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_result_blob64(), sqlite3_bind_text64(), and sqlite3_result_text64().
* Added the new interface sqlite3_msize() that returns the size of a memory allocation obtained from sqlite3_malloc64() and its variants.
* Added the SQLITE_LIMIT_WORKER_THREADS option to sqlite3_limit() and PRAGMA threads command for configuring the number of available worker threads.
* The spellfix1 extension allows the application to optionally specify the rowid for each INSERT.
* Added the User Authentication extension.

Bug Fixes:
* Fix a bug in the partial index implementation that might result in an incorrect answer if a partial index is used in a subquery or in a view.
* Fix a query planner bug that might cause a table to be scanned in the wrong direction (thus reversing the order of output) when a DESC index is used to implement the ORDER BY clause on a query that has an identical GROUP BY clause.
* Fix a bug in sqlite3_trace() that was causing it to sometimes fail to print an SQL statement if that statement needed to be re-prepared.
* Fix a faulty assert() statement.

Enhanced the PRAGMA integrity_check command to detect UNIQUE and NOT NULL constraint violations.
Increase the maximum value of SQLITE_MAX_ATTACHED from 62 to 125.
Increase the timeout in WAL mode before issuing an SQLITE_PROTOCOL error from 1 second to 10 seconds.

Add extension functions readfile(X) and writefile(X,Y) (using code copy/pasted from fileio.c in the previous bullet) to the command-line shell.
Added the .fullschema dot-command to the command-line shell.

Performance Enhancements:
Deactivate the DISTINCT keyword on subqueries on the right-hand side of the IN operator.
Add the capability of evaluating an IN operator as a sequence of comparisons as an alternative to using a table lookup. Use the sequence of comparisons implementation in circumstances where it is likely to be faster, such as when the right-hand side of the IN operator is small and/or changes frequently.
The query planner now uses sqlite_stat4 information (created by ANALYZE) to help determine if the skip-scan optimization is appropriate.
Ensure that the query planner never tries to use a self-made transient index in place of a schema-defined index.
Other minor tweaks to improve the quality of VDBE code.

Bug Fixes:
Fix a bug in CREATE UNIQUE INDEX, introduced when WITHOUT ROWID support added in version 3.8.2, that allows a non-unique NOT NULL column to be given a UNIQUE index.
Fix a bug in R-Tree extension, introduced in the previous release, that can cause an incorrect results for queries that use the rowid of the R-Tree on the left-hand side of an IN operator.
Fix the sqlite3_stmt_busy() interface so that it gives the correct answer for ROLLBACK statements that have been stepped but never reset.
Fix a bug in that would cause a null pointer to be dereferenced if a column with a DEFAULT that is an aggregate function tried to usee its DEFAULT.
CSV output from the command-line shell now always uses CRNL for the row separator and avoids inserting CR in front of NLs contained in data.

Changes 3.8.5:
Added support for partial sorting by index.
Enhance the query planner so that it always prefers an index that uses a superset of WHERE clause terms relative to some other index.
Improvements to the automerge command of FTS4 to better control the index size for a full-text index that is subject to a large number of updates.
Added the sqlite3_rtree_query_callback() interface to R-Tree extension
Added new URI query parameters "nolock" and "immutable".
Use less memory by not remembering CHECK constraints on read-only database connections.
Enable the OR optimization for WITHOUT ROWID tables.
Render expressions of the form "x IN (?)" (with a single value in the list on the right-hand side of the IN operator) as if they where "x==?", Similarly optimize "x NOT IN (?)"
Add the ".system" and ".once" commands to the command-line shell.
Added the SQLITE_IOCAP_IMMUTABLE bit to the set of bits that can be returned by the xDeviceCharacteristics method of a VFS.
Added the SQLITE_TESTCTRL_BYTEORDER test control.

Bug Fixes:
OFFSET clause ignored on queries without a FROM clause.
Assertion fault on queries involving expressions of the form "x IN (?)".
Incorrect column datatype reported.
Duplicate row returned on a query against a table with more than 16 indices, each on a separate column, and all used via OR-connected constraints.
Partial index causes assertion fault on UPDATE OR REPLACE.
Crash when calling undocumented SQL function sqlite_rename_parent() with NULL parameters.
ORDER BY ignored if the query has an identical GROUP BY.
The group_concat(x,'') SQL function returns NULL instead of an empty string when all inputs are empty strings.
Fix a bug in the VDBE code generator that caused crashes when doing an INSERT INTO ... SELECT statement where the number of columns being inserted is larger than the number of columns in the destination table.
Fix a problem in CSV import in the command-line shell where if the leftmost field of the first row in the CSV file was both zero bytes in size and unquoted no data would be imported.
Fix a problem in FTS4 where the left-most column that contained the notindexed column name as a prefix was not indexed rather than the column whose name matched exactly.
Fix the sqlite3_db_readonly() interface so that it returns true if the database is read-only due to the file format write version number being too large.

Changes 3.8.2:
Changed the defined behavior for the CAST expression when floating point values greater than +9223372036854775807 are cast into into integers so that the result is the largest possible integer, +9223372036854775807, instead of the smallest possible integer, -9223372036854775808. After this change, CAST(9223372036854775809.0 as INT) yields +9223372036854775807 instead of -9223372036854775808. ŃŠPotentially Incompatible Change!
Added support for WITHOUT ROWID tables.
Added the skip-scan optimization to the query planner.
Extended the virtual table interface, and in particular the sqlite3_index_info object to allow a virtual table to report its estimate on the number of rows that will be returned by a query.
Update the R-Tree extension to make use of the enhanced virtual table interface.

Factor constant subexpressions in inner loops out to the initialization code in prepared statements.
Enhanced the ".explain" output formatting of the command-line shell so that loops are indented to better show the structure of the program.
Enhanced the ".timer" feature of the command-line shell so that it shows wall-clock time in addition to system and user times.

Changes 3.8.1:
Added the unlikely() and likelihood() SQL functions to be used as hints to the query planner.
Enhancements to the query planner:
Take into account the fact WHERE clause terms that cannot be used with indices still probably reduce the number of output rows.
Estimate the sizes of table and index rows and use the smallest applicable B-Tree for full scans and "count(*)" operations.
Added the soft_heap_limit pragma.
Added support for SQLITE_ENABLE_STAT4
Added support for "sz=NNN" parameters at the end of sqlite_stat1.stat fields used to specify the average length in bytes for table and index rows.
Avoid running foreign-key constraint checks on an UPDATE if none of the modified columns are associated with foreign keys.
Added the SQLITE_MINIMUM_FILE_DESCRIPTOR compile-time option
Added the win32-longpath VFS on windows, permitting filenames up to 32K characters in length.
The Date And Time Functions are enhanced so that the current time (ex: julianday('now')) is always the same for multiple function invocations within the same sqlite3_step() call.
Add the "totype.c" extension, implementing the tointeger() and toreal() SQL functions.
FTS4 queries are better able to make use of docid<$limit constraints to limit the amount of I/O required.
Added the hidden fts4aux languageid column to the fts4aux virtual table.
The VACUUM command packs the database about 1% tighter.
The sqlite3_analyzer utility program is updated to provide better descriptions and to compute a more accurate estimate for "Non-sequential pages"
Refactor the implementation of PRAGMA statements to improve parsing performance.
The directory used to hold temporary files on unix can now be set using the SQLITE_TMPDIR environment variable, which takes precedence over the TMPDIR environment variable. The sqlite3_temp_directory global variable still has higher precedence than both environment variables, however.
Added the PRAGMA stats statement.
Bug fix: Return the correct answer for "SELECT count(*) FROM table" even if there is a partial index on the table.

Add support for partial indexes
Cut-over to the next generation query planner for faster and better query plans.
The EXPLAIN QUERY PLAN output no longer shows an estimate of the number of rows generated by each loop in a join.
Added the FTS4 notindexed option, allowing non-indexed columns in an FTS4 table.
Added the SQLITE_STMTSTATUS_VM_STEP option to sqlite3_stmt_status().
Added the cache_spill pragma.
Added the query_only pragma.
Added the defer_foreign_keys pragma and the sqlite3_db_status(db, SQLITE_DBSTATUS_DEFERRED_FKS,...) C-language interface.
Added the "percentile()" function as a loadable extension in the ext/misc subdirectory of the source tree.
Added the SQLITE_ALLOW_URI_AUTHORITY compile-time option.
Add the sqlite3_cancel_auto_extension(X) interface.
A running SELECT statement that lacks a FROM clause (or any other statement that never reads or writes from any database file) will not prevent a read transaction from closing.
Add the SQLITE_DEFAULT_AUTOMATIC_INDEX compile-time option. Setting this option to 0 disables automatic indices by default.
Issue an SQLITE_WARNING_AUTOINDEX warning on the SQLITE_CONFIG_LOG whenever the query planner uses an automatic index.
Added the SQLITE_FTS3_MAX_EXPR_DEPTH compile-time option.
Added an optional 5th parameter defining the collating sequence to the next_char() extension SQL function.
The SQLITE_BUSY_SNAPSHOT extended error code is returned in WAL mode when a read transaction cannot be upgraded to a write transaction because the read is on an older snapshot.
Enhancements to the sqlite3_analyzer utility program to provide size information separately for each individual index of a table, in addition to the aggregate size.
Allow read transactions to be freely opened and closed by SQL statements run from within the implementation of application-defined SQL functions if the function is called by a SELECT statement that does not access any database table.
Disable the use of posix_fallocate() on all (unix) systems unless the HAVE_POSIX_FALLOCATE compile-time option is used.
Update the ".import" command in the command-line shell to support multi-line fields and correct RFC-4180 quoting and to issue warning and/or error messages if the input text is not strictly RFC-4180 compliant.
Bug fix: In the unicode61 tokenizer of FTS4, treat all private code points as identifier symbols.
Bug fix: Bare identifiers in ORDER BY clauses bind more tightly to output column names, but identifiers in expressions bind more tightly to input column names. Identifiers in GROUP BY clauses always prefer output column names, however.
Bug fixes: Multiple problems in the legacy query optimizer were fixed by the move to NGQP.

Changes 3.7.17:
Add support for memory-mapped I/O.
Add the sqlite3_strglob() convenience interface.
Assigned the integer at offset 68 in the database header as the Application ID for when SQLite is used as an application file-format. Added the PRAGMA application_id command to query and set the Application ID.
Report rollback recovery in the error log as SQLITE_NOTICE_RECOVER_ROLLBACK. Change the error log code for WAL recover from SQLITE_OK to SQLITE_NOTICE_RECOVER_WAL.
Report the risky uses of unlinked database files and database filename aliasing as SQLITE_WARNING messages in the error log.
Added the SQLITE_TRACE_SIZE_LIMIT compile-time option.
Increase the default value of SQLITE_MAX_SCHEMA_RETRY to 50 and make sure that it is honored in every place that a schema change might force a statement retry.
Add a new test harness called "mptester" used to verify correct operation when multiple processes are using the same database file at the same time.
Enhance the extension loading mechanism to be more flexible (while still maintaining backwards compatibility) in two ways:
If the default entry point "sqlite3_extension_init" is not present in the loadable extension, also try an entry point "sqlite3_X_init" where "X" is based on the shared library filename. This allows every extension to have a different entry point, which allows them to be statically linked with no code changes.
The shared library filename passed to sqlite3_load_extension() may omit the filename suffix, and an appropriate architecture-dependent suffix (".so", ".dylib", or ".dll") will be added automatically.
Added many new loadable extensions to the source tree, including amatch, closure, fuzzer, ieee754, nextchar, regexp, spellfix, and wholenumber. See header comments on each extension source file for further information about what that extension does.
Enhance FTS3 to avoid using excess stack space when there are a huge number of terms on the right-hand side of the MATCH operator. A side-effect of this change is that the MATCH operator can only accommodate 12 NEAR operators at a time.
Enhance the fts4aux virtual table so that it can be a TEMP table.
Added the fts3tokenize virtual table to the full-text search logic.
Query planner enhancement: Use the transitive property of constraints to move constraints into the outer loops of a join whenever possible, thereby reducing the amount of work that needs to occur in inner loops.
Discontinue the use of posix_fallocate() on unix, as it does not work on all filesystems.
Improved tracing and debugging facilities in the Windows VFS.
Bug fix: Fix a potential database corruption bug in shared cache mode when one database connection is closed while another is in the middle of a write transaction.
Bug fix: Only consider AS names from the result set as candidates for resolving identifiers in the WHERE clause if there are no other matches. In the ORDER BY clause, AS names take priority over any column names.
Bug fix: Do not allow a virtual table to cancel the ORDER BY clause unless all outer loops are guaranteed to return no more than one row result.
Bug fix: Do not suppress the ORDER BY clause on a virtual table query if an IN constraint is used.
Bug fix: The command-line shell gives an exit code of 0 when terminated using the ".quit" command.
Bug fix: Make sure PRAGMA statements appear in sqlite3_trace() output.
Bug fix: When a compound query that uses an ORDER BY clause with a COLLATE operator, make sure that the sorting occurs according to the specified collation and that the comparisons associate with the compound query use the native collation.
Bug fix: Makes sure the authorizer callback gets a valid pointer to the string "ROWID" for the column-name parameter when doing an UPDATE that changes the rowid.
Bug fix: Do not move WHERE clause terms inside OR expressions that are contained within an ON clause of a LEFT JOIN.
Bug fix: Make sure an error is always reported when attempting to preform an operation that requires a collating sequence that is missing.

* Bug fix: Do not discard the DISTINCT as superfluous unless a subset of the result set is subject to a UNIQUE constraint and it none of the columns in that subset can be NULL.
* Bug fix: Do not optimize away an ORDER BY clause that has the same terms as a UNIQUE index unless those terms are also NOT NULL.

Changes 3.7.11:
* Enhance the INSERT syntax to allow multiple rows to be inserted via
  the VALUES clause.
* Enhance the CREATE VIRTUAL TABLE command to support the IF NOT EXISTS clause.
* Added the sqlite3_stricmp() interface as a counterpart to sqlite3_strnicmp().
* Added the sqlite3_db_readonly() interface.
* Added the SQLITE_FCNTL_PRAGMA file control, giving VFS implementations
  the ability to add new PRAGMA statements or to override built-in PRAGMAs.
* Queries of the form: "SELECT max(x), y FROM table" returns the value of y on
  the same row that contains the maximum x value.
* Added support for the FTS4 languageid option.
* Documented support for the FTS4 content option. This feature has actually
  been in the code since version 3.7.9 but is only now considered to be
  officially supported.
* Pending statements no longer block ROLLBACK. Instead, the pending statement
  will return SQLITE_ABORT upon next access after the ROLLBACK.
* Improvements to the handling of CSV inputs in the command-line shell
* Fix a bug introduced in version 3.7.10 that might cause a LEFT JOIN to be
  incorrectly converted into an INNER JOIN if the WHERE clause indexable terms
  connected by OR.

Changes 3.7.10:
* The default schema format number is changed from 1 to 4. This means that,
  unless the PRAGMA legacy_file_format=ON statement is run, newly created
  database files will be unreadable by version of SQLite prior to 3.3.0
  (2006-01-10). It also means that the descending indices are enabled by
* The sqlite3_pcache_methods structure and the SQLITE_CONFIG_PCACHE and
  SQLITE_CONFIG_GETPCACHE configuration parameters are deprecated. They are
  replaced by a new sqlite3_pcache_methods2 structure and SQLITE_CONFIG_PCACHE2
  and SQLITE_CONFIG_GETPCACHE2 configuration parameters.
* Added the powersafe overwrite property to the VFS interface. Provide the
  SQLITE_POWERSAFE_OVERWRITE compile-time option, and the "psow=BOOLEAN" query
  parameter for URI filenames.
* Added the sqlite3_db_release_memory() interface and the shrink_memory pragma.
* Added the sqlite3_db_filename() interface.
* Added the sqlite3_stmt_busy() interface.
* Added the sqlite3_uri_boolean() and sqlite3_uri_int64() interfaces.
* If the argument to PRAGMA cache_size is negative N, that means to use
  approximately -1024*N bytes of memory for the page cache regardless of the
  page size.
* Enhanced the default memory allocator to make use of _msize() on windows,
  malloc_size() on Mac, and malloc_usable_size() on Linux.
* Enhanced the query planner to support index queries with range constraints on
  the rowid.
* Enhanced the query planner flattening logic to allow UNION ALL compounds to
  be promoted upwards to replace a simple wrapper SELECT even if the compounds
  are joins.
* Enhanced the query planner so that the xfer optimization can be used with
  INTEGER PRIMARY KEY ON CONFLICT as long as the destination table is initially
* Enhanced the windows VFS so that all system calls can be overridden using the
  xSetSystemCall interface.
* Updated the "unix-dotfile" VFS to use locking directories with mkdir() and
  rmdir() instead of locking files with open() and unlink().
* Enhancements to the test_quota.c extension to support stdio-like interfaces
  with quotas.
* Change the unix VFS to be tolerant of read() system calls that return less
  then the full number of requested bytes.
* Change both unix and windows VFSes to report a sector size of 4096 instead of
  the old default of 512.
* In the TCL Interface, add the -uri option to the "sqlite3" TCL command used
  for creating new database connection objects.
* Added the SQLITE_TESTCTRL_EXPLAIN_STMT test-control option with the
  SQLITE_ENABLE_TREE_EXPLAIN compile-time option to enable the command-line
  shell to display ASCII-art parse trees of SQL statements that it processes,
  for debugging and analysis.
* Bug fix: Add an additional xSync when restarting a WAL in order to prevent an
  exceedingly unlikely but theoretically possible database corruption following
* Bug fix: Change the VDBE so that all registers are initialized to Invalid
  instead of NULL.
* Bug fix: Fix problems that can result from 32-bit integer overflow.

Changes 3.7.9:
* If a search token (on the right-hand side of the MATCH operator) in FTS4
  begins with "^" then that token must be the first in its field of the
  document. ** Potentially Incompatible Change **
  sqlite3_db_status() interface.
* Removed support for SQLITE_ENABLE_STAT2, replacing it with the much more
  capable SQLITE_ENABLE_STAT3 option.
* Enhancements to the sqlite3_analyzer utility program, including the --pageinfo
  and --stats options and support for multiplexed databases.
* Enhance the sqlite3_data_count() interface so that it can be used to determine
  if SQLITE_DONE has been seen on the prepared statement.
* Added the SQLITE_FCNTL_OVERWRITE file-control by which the SQLite core
  indicates to the VFS that the current transaction will overwrite the entire
  database file.
* Increase the default lookaside memory allocator allocation size from 100 to
  128 bytes.
* Enhanced the query planner so that it can factor terms in and out of OR
  expressions in the WHERE clause in an effort to find better indices.
* Added the SQLITE_DIRECT_OVERFLOW_READ compile-time option, causing overflow
  pages to be read directly from the database file, bypassing the page cache.
* Remove limits on the magnitude of precision and width value in the format
  specifiers of the sqlite3_mprintf() family of string rendering routines.
* Fix a bug that prevent ALTER TABLE ... RENAME from working on some virtual
  tables in a database with a UTF16 encoding.
* Fix a bug in ASCII-to-float conversion that causes slow performance and
  incorrect results when converting numbers with ridiculously large exponents.
* Fix a bug that causes incorrect results in aggregate queries that use
  multiple aggregate functions whose arguments contain complicated expressions
  that differ only in the case of string literals contained within those
* Fix a bug that prevented the page_count and quick_check pragmas from working
  correctly if their names were capitalized.
* Fix a bug that caused VACUUM to fail if the count_changes pragma was engaged.
* Fix a bug in virtual table implementation that causes a crash if an FTS4
  table is dropped inside a transaction and a SAVEPOINT occurs afterwards.

Changes 3.7.8:
* Orders of magnitude performance improvement for CREATE INDEX on very large
* Improved the windows VFS to better defend against interference from
  anti-virus software.
* Improved query plan optimization when the DISTINCT keyword is present.
* Allow more system calls to be overridden in the unix VFS - to provide better
  support for chromium sandboxes.
* Increase the default size of a lookahead cache line from 100 to 128 bytes.
* Enhancements to the test_quota.c module so that it can track preexisting
* Bug fix: Virtual tables now handle IS NOT NULL constraints correctly.
* Bug fixes: Correctly handle nested correlated subqueries used with indices in
  a WHERE clause.

Changes 3.7.7:
* Add support for URI filenames
* Add the sqlite3_vtab_config() interface in support of ON CONFLICT clauses
  with virtual tables.
* Add the xSavepoint, xRelease and xRollbackTo methods in virtual tables in
  support of SAVEPOINT for virtual tables.
* Update the built-in FTS3/FTS4 and RTREE virtual tables to support ON CONFLICT
  clauses and REPLACE.
* Avoid unnecessary reparsing of the database schema.
* Added support for the FTS4 prefix option and the FTS4 order option.
* Allow WAL-mode databases to be opened read-only as long as there is an
  existing read/write connection.
* Added support for short filenames.

  and SQLITE_DBSTATUS_LOOKASIDE_MISS_FULL options for the sqlite3_db_status()
* Added the SQLITE_OMIT_AUTORESET compile-time option.
* Added the SQLITE_DEFAULT_FOREIGN_KEYS compile-time option.
* Updates to sqlite3_stmt_readonly() so that its result is well-defined for all
  prepared statements and so that it works with VACUUM.
* Added the "-heap" option to the command-line shell
* Fix a bug involving frequent changes in and out of WAL mode and VACUUM that
  could (in theory) cause database corruption.
* Enhance the sqlite3_trace() mechanism so that nested SQL statements such as
  might be generated by virtual tables are shown but are shown in comments and
  without parameter expansion. This greatly improves tracing output when using
  the FTS3/4 and/or RTREE virtual tables.
* Change the xFileControl() methods on all built-in VFSes to return
  SQLITE_NOTFOUND instead of SQLITE_ERROR for an unrecognized operation code.
* The SQLite core invokes the SQLITE_FCNTL_SYNC_OMITTED file control to the VFS
  in place of a call to xSync if the database has PRAGMA synchronous set to OFF.
