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.

Changes 3.7.5: * Added the sqlite3_vsnprintf() interface. * Added the SQLITE_DBSTATUS_LOOKASIDE_HIT, SQLITE_DBSTATUS_LOOKASIDE_MISS_SIZE, and SQLITE_DBSTATUS_LOOKASIDE_MISS_FULL options for the sqlite3_db_status() interface. * 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.

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 3.8.3: Added support for common table expressions and the WITH clause. Added the printf() SQL function. Added SQLITE_DETERMINISTIC as an optional bit in the 4th argument to the sqlite3_create_function() and related interfaces, providing applications with the ability to create new functions that can be factored out of inner loops when they have constant arguments. Add SQLITE_READONLY_DBMOVED error code, returned at the beginning of a transaction, to indicate that the underlying database file has been renamed or moved out from under SQLite. Allow arbitrary expressions, including function calls and subqueries, in the filename argument to ATTACH. Allow a VALUES clause to be used anywhere a SELECT statement is valid. Reseed the PRNG used by sqlite3_randomness(N,P) when invoked with N==0. Automatically reseed after a fork() on unix. Enhance the spellfix1 virtual table so that it can search efficiently by rowid. Performance enhancements. Improvements to the comments in the VDBE byte-code display when running EXPLAIN. Add the "%token_class" directive to LEMON parser generator and use it to simplify the grammar. Change the LEMON source code to avoid calling C-library functions that OpenBSD considers dangerous. (Ex: sprintf). Bug fix: In the command-line shell CSV import feature, do not end a field when an escaped double-quote occurs at the end of a CRLN line.

Changes 3.8.0.1: 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 3.7.13: * In-memory databases that are specified using URI filenames are allowed to use shared cache, so that the same in-memory database can be accessed from multiple database connections. * Recognize and use the mode=memory query parameter in URI filenames. * Avoid resetting the schema of shared cache connections when any one connection closes. Instead, wait for the last connection to close before reseting the schema. * In the RTREE extension, when rounding 64-bit floating point numbers to 32-bit for storage, always round in a direction that causes the bounding box to get larger. * Adjust the unix driver to avoid unnecessary calls to fchown(). * Add interfaces sqlite3_quota_ferror() and sqlite3_quota_file_available() to the test_quota.c module. * The sqlite3_create_module() and sqlite3_create_module_v2() interfaces return SQLITE_MISUSE on any attempt to overload or replace a virtual table module. The destructor is always called in this case, in accordance with historical and current documentation.

share/doc/sqlite3/c3ref/db_config.html
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 default. * 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_IOCAP_POWERSAFE_OVERWRITE I/O capability, 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 empty. * 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 power-loss. * 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 3.7.17: 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.

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 3.8.5: 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 3.7.17: 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.

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 3.8.0.1: 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 3.7.15: * Added the sqlite3_errstr() interface. * Avoid invoking the sqlite3_trace() callback multiple times when a statement is automatically reprepared due to SQLITE_SCHEMA errors. * Added support for Windows Phone 8 platforms * Enhance IN operator processing to make use of indices with numeric affinities. * Do full-table scans using covering indices when possible, under the theory that an index will be smaller and hence can be scanned with less I/O. * Enhance the query optimizer so that ORDER BY clauses are more aggressively optimized, especially in joins where various terms of the ORDER BY clause come from separate tables of the join. * Add the ability to implement FROM clause subqueries as coroutines rather that manifesting the subquery into a temporary table. * Enhancements the command-line shell: * Added the ".print" command * Negative numbers in the ".width" command cause right-alignment * Add the ".wheretrace" command when compiled with SQLITE_DEBUG * Added the busy_timeout pragma. * Added the instr() SQL function. * Added the SQLITE_FCNTL_BUSYHANDLER file control, used to allow VFS implementations to get access to the busy handler callback. * The xDelete method in the built-in VFSes now return SQLITE_IOERR_DELETE_NOENT if the file to be deleted does not exist. * Enhanced support for QNX. * Work around an optimizer bug in the MSVC compiler when targeting ARM. * Bug fix: Avoid various concurrency problems in shared cache mode. * Bug fix: Avoid a deadlock or crash if the backup API, shared cache, and the SQLite Encryption Extension are all used at once. * Bug fix: SQL functions created using the TCL interface honor the "nullvalue" setting. * Bug fix: Fix a 32-bit overflow problem on CREATE INDEX for databases larger than 16GB. * Bug fix: Avoid segfault when using the COLLATE operator inside of a CHECK constraint or view in shared cache mode.

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.

Changes 3.8.6: Added support for hexadecimal integer literals in the SQL parser. (Ex: 0x123abc) 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. Added the likely(X) SQL function. The unicode61 tokenizer is now included in FTS4 by default. Trigger automatic reprepares on all prepared statements when ANALYZE is run. Added a new loadable extension source code file to the source tree: fileio.c 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. Fix a column affinity problem with the IN operator. Fix the ANALYZE command so that it adds correct samples for WITHOUT ROWID tables in the sqlite_stat4 table.

If you need to upgrade an OS/2 application to use this or a later version of SQLite, then add an application-defined VFS using the sqlite3_vfs_register() interface. The code removed in this release can serve as a baseline for the application-defined VFS. * Ensure that floating point values are preserved exactly when reconstructing a database from the output of the ".dump" command of the command-line shell. * Added the sqlite3_close_v2() interface. * Updated the command-line shell so that it can be built using SQLITE_OMIT_FLOATING_POINT and SQLITE_OMIT_AUTOINIT. * Improvements to the windows makefiles and build processes. * Enhancements to PRAGMA integrity_check and PRAGMA quick_check so that they can optionally check just a single attached database instead of all attached databases. * Enhancements to WAL mode processing that ensure that at least one valid read-mark is available at all times, so that read-only processes can always read the database. * Performance enhancements in the sorter used by ORDER BY and CREATE INDEX. * Added the SQLITE_DISABLE_FTS4_DEFERRED compile-time option. * Better handling of aggregate queries where the aggregate functions are contained within subqueries. * Enhance the query planner so that it will try to use a covering index on queries that make use of or optimization.

Changes 3.7.16.1: * Fix for a bug in the ORDER BY optimizer that was introduced in version 3.7.15 which would sometimes optimize out the sorting step when in fact the sort was required. Ticket a179fe7465 * Fix a long-standing bug in the CAST expression that would recognize UTF16 characters as digits even if their most-significant-byte was not zero. Ticket 689137afb6da41. * Fix a bug in the NEAR operator of FTS3 when applied to subfields. Ticket 38b1ae018f. * Fix a long-standing bug in the storage engine that would (very rarely) cause a spurious report of an SQLITE_CORRUPT error but which was otherwise harmless. Ticket 6bfb98dfc0c. * The SQLITE_OMIT_MERGE_SORT option has been removed. The merge sorter is now a required component of SQLite. * Fixed lots of spelling errors in the source-code comments

Changes 3.8.0.1: 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 3.8.5: 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 3.7.17: 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.

Changes 3.8.3: Added support for common table expressions and the WITH clause. Added the printf() SQL function. Added SQLITE_DETERMINISTIC as an optional bit in the 4th argument to the sqlite3_create_function() and related interfaces, providing applications with the ability to create new functions that can be factored out of inner loops when they have constant arguments. Add SQLITE_READONLY_DBMOVED error code, returned at the beginning of a transaction, to indicate that the underlying database file has been renamed or moved out from under SQLite. Allow arbitrary expressions, including function calls and subqueries, in the filename argument to ATTACH. Allow a VALUES clause to be used anywhere a SELECT statement is valid. Reseed the PRNG used by sqlite3_randomness(N,P) when invoked with N==0. Automatically reseed after a fork() on unix. Enhance the spellfix1 virtual table so that it can search efficiently by rowid. Performance enhancements. Improvements to the comments in the VDBE byte-code display when running EXPLAIN. Add the "%token_class" directive to LEMON parser generator and use it to simplify the grammar. Change the LEMON source code to avoid calling C-library functions that OpenBSD considers dangerous.

Changes 3.8.3: Added support for common table expressions and the WITH clause. Added the printf() SQL function. Added SQLITE_DETERMINISTIC as an optional bit in the 4th argument to the sqlite3_create_function() and related interfaces, providing applications with the ability to create new functions that can be factored out of inner loops when they have constant arguments.

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 ** * Added options SQLITE_DBSTATUS_CACHE_HIT and SQLITE_DBSTATUS_CACHE_MISS to the 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 expressions. * 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 3.8.0.1: 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.

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.

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.

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.

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 default. * 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_IOCAP_POWERSAFE_OVERWRITE I/O capability, 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 empty. * 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 power-loss. * 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.

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.

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 default. * 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_IOCAP_POWERSAFE_OVERWRITE I/O capability, 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 empty. * 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 power-loss. * 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 3.7.11: * 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.
2012-03-20 22:00:47 +01:00
share/doc/sqlite3/releaselog/3_7_11.html
Changes 3.7.12: * Add the SQLITE_DBSTATUS_CACHE_WRITE option for sqlite3_db_status(). * Optimize the typeof() and length() SQL functions so that they avoid unnecessary reading of database content from disk. * Add the FTS4 "merge" command, the FTS4 "automerge" command, and the FTS4 "integrity-check" command. * Report the name of specific CHECK constraints that fail. * In the command-line shell, use popen() instead of fopen() if the first character of the argument to the ".output" command is "|". * Make use of OVERLAPPED in the windows VFS to avoid some system calls and thereby obtain a performance improvement. * More aggressive optimization of the AND operator when one side or the other is always false. * Improved performance of queries with many OR-connected terms in the WHERE clause that can all be indexed. * Add the SQLITE_RTREE_INT_ONLY compile-time option to force the R*Tree Extension Module to use integer instead of floating point values for both storage and computation. * Enhance the PRAGMA integrity_check command to use much less memory when processing multi-gigabyte databases. * New interfaces added to the test_quota.c add-on module. * Added the ".trace" dot-command to the command-line shell. * Allow virtual table constructors to be invoked recursively. * Improved optimization of ORDER BY clauses on compound queries. * Improved optimization of aggregate subqueries contained within an aggregate query. * Bug fix: Fix the RELEASE command so that it does not cancel pending queries. This repairs a problem introduced in 3.7.11. * 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 3.7.13: * In-memory databases that are specified using URI filenames are allowed to use shared cache, so that the same in-memory database can be accessed from multiple database connections. * Recognize and use the mode=memory query parameter in URI filenames. * Avoid resetting the schema of shared cache connections when any one connection closes. Instead, wait for the last connection to close before reseting the schema. * In the RTREE extension, when rounding 64-bit floating point numbers to 32-bit for storage, always round in a direction that causes the bounding box to get larger. * Adjust the unix driver to avoid unnecessary calls to fchown(). * Add interfaces sqlite3_quota_ferror() and sqlite3_quota_file_available() to the test_quota.c module. * The sqlite3_create_module() and sqlite3_create_module_v2() interfaces return SQLITE_MISUSE on any attempt to overload or replace a virtual table module. The destructor is always called in this case, in accordance with historical and current documentation.
2012-06-11 18:21:30 +02:00
share/doc/sqlite3/releaselog/3_7_13.html
Changes 3.7.14: * Drop built-in support for OS/2. If you need to upgrade an OS/2 application to use this or a later version of SQLite, then add an application-defined VFS using the sqlite3_vfs_register() interface. The code removed in this release can serve as a baseline for the application-defined VFS. * Ensure that floating point values are preserved exactly when reconstructing a database from the output of the ".dump" command of the command-line shell. * Added the sqlite3_close_v2() interface. * Updated the command-line shell so that it can be built using SQLITE_OMIT_FLOATING_POINT and SQLITE_OMIT_AUTOINIT. * Improvements to the windows makefiles and build processes. * Enhancements to PRAGMA integrity_check and PRAGMA quick_check so that they can optionally check just a single attached database instead of all attached databases. * Enhancements to WAL mode processing that ensure that at least one valid read-mark is available at all times, so that read-only processes can always read the database. * Performance enhancements in the sorter used by ORDER BY and CREATE INDEX. * Added the SQLITE_DISABLE_FTS4_DEFERRED compile-time option. * Better handling of aggregate queries where the aggregate functions are contained within subqueries. * Enhance the query planner so that it will try to use a covering index on queries that make use of or optimization.

share/doc/sqlite3/releaselog/3_7_14.html
Changes 3.7.15: * Added the sqlite3_errstr() interface. * Avoid invoking the sqlite3_trace() callback multiple times when a statement is automatically reprepared due to SQLITE_SCHEMA errors. * Added support for Windows Phone 8 platforms * Enhance IN operator processing to make use of indices with numeric affinities. * Do full-table scans using covering indices when possible, under the theory that an index will be smaller and hence can be scanned with less I/O. * Enhance the query optimizer so that ORDER BY clauses are more aggressively optimized, especially in joins where various terms of the ORDER BY clause come from separate tables of the join. * Add the ability to implement FROM clause subqueries as coroutines rather that manifesting the subquery into a temporary table. * Enhancements the command-line shell: * Added the ".print" command * Negative numbers in the ".width" command cause right-alignment * Add the ".wheretrace" command when compiled with SQLITE_DEBUG * Added the busy_timeout pragma. * Added the instr() SQL function. * Added the SQLITE_FCNTL_BUSYHANDLER file control, used to allow VFS implementations to get access to the busy handler callback. * The xDelete method in the built-in VFSes now return SQLITE_IOERR_DELETE_NOENT if the file to be deleted does not exist. * Enhanced support for QNX. * Work around an optimizer bug in the MSVC compiler when targeting ARM. * Bug fix: Avoid various concurrency problems in shared cache mode. * Bug fix: Avoid a deadlock or crash if the backup API, shared cache, and the SQLite Encryption Extension are all used at once. * Bug fix: SQL functions created using the TCL interface honor the "nullvalue" setting. * Bug fix: Fix a 32-bit overflow problem on CREATE INDEX for databases larger than 16GB. * Bug fix: Avoid segfault when using the COLLATE operator inside of a CHECK constraint or view in shared cache mode.

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.

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 ** * Added options SQLITE_DBSTATUS_CACHE_HIT and SQLITE_DBSTATUS_CACHE_MISS to the 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 expressions. * 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 3.8.0.1: 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 3.8.0.2: Fix an off-by-one error that caused quoted empty string at the end of a CRNL-terminated line of CSV input to be misread by the command-line shell. Fix a query planner bug involving a LEFT JOIN with a BETWEEN or LIKE/GLOB constraint and then another INNER JOIN to the right that involves an OR constraint. Fix a query planner bug that could result in a segfault when querying tables with a UNIQUE or PRIMARY KEY constraint with more than four columns.

share/doc/sqlite3/releaselog/3_8_0_2.html
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.

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. ← Potentially 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. Add the SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option. Enhanced the comments that are inserted into EXPLAIN output when the SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option is enabled. Performance enhancements in the VDBE, especially to the OP_Column opcode. 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.

share/doc/sqlite3/releaselog/3_8_2.html
Changes 3.8.3: Added support for common table expressions and the WITH clause. Added the printf() SQL function. Added SQLITE_DETERMINISTIC as an optional bit in the 4th argument to the sqlite3_create_function() and related interfaces, providing applications with the ability to create new functions that can be factored out of inner loops when they have constant arguments. Add SQLITE_READONLY_DBMOVED error code, returned at the beginning of a transaction, to indicate that the underlying database file has been renamed or moved out from under SQLite. Allow arbitrary expressions, including function calls and subqueries, in the filename argument to ATTACH. Allow a VALUES clause to be used anywhere a SELECT statement is valid. Reseed the PRNG used by sqlite3_randomness(N,P) when invoked with N==0. Automatically reseed after a fork() on unix. Enhance the spellfix1 virtual table so that it can search efficiently by rowid. Performance enhancements. Improvements to the comments in the VDBE byte-code display when running EXPLAIN. Add the "%token_class" directive to LEMON parser generator and use it to simplify the grammar. Change the LEMON source code to avoid calling C-library functions that OpenBSD considers dangerous. (Ex: sprintf). Bug fix: In the command-line shell CSV import feature, do not end a field when an escaped double-quote occurs at the end of a CRLN line.

Changes 3.8.3.1: Fix a bug (ticket 4c86b126f2) that causes rows to go missing on some queries with OR clauses and IS NOT NULL operators in the WHERE clause, when the SQLITE_ENABLE_STAT3 or SQLITE_ENABLE_STAT4 compile-time options are used. Fix a harmless compiler warning that was causing problems for VS2013.

Changes 3.8.4: Code optimization and refactoring for improved performance. Add the ".clone" and ".save" commands to the command-line shell. Update the banner on the command-line shell to alert novice users when they are using an ephemeral in-memory database. Fix editline support in the command-line shell. Add support for coverage testing of VDBE programs using the SQLITE_TESTCTRL_VDBE_COVERAGE verb of sqlite3_test_control(). Update the _FILE_OFFSET_BITS macro so that builds work again on QNX. Change the datatype of SrcList.nSrc from type u8 to type int to work around an issue in the C compiler on AIX. Get extension loading working on Cygwin. Bug fix: Fix the char() SQL function so that it returns an empty string rather than an "out of memory" error when called with zero arguments. Bug fix: DISTINCT now recognizes that a zeroblob and a blob of all 0x00 bytes are the same thing. Ticket [fccbde530a] Bug fix: Compute the correct answer for queries that contain an IS NOT NULL term in the WHERE clause and also contain an OR term in the WHERE clause and are compiled with SQLITE_ENABLE_STAT4. Ticket [4c86b126f2] Bug fix: Make sure "rowid" columns are correctly resolved in joins between normal tables and WITHOUT ROWID tables. Ticket [c34d0557f7] Bug fix: Make sure the same temporary registers are not used in concurrent co-routines used to implement compound SELECT statements containing ORDER BY clauses, as such use can lead to incorrect answers. Ticket [8c63ff0eca] Bug fix: Ensure that "ORDER BY random()" clauses do not get optimized out. Ticket [65bdeb9739] Bug fix: Repair a name-resolution error that can occur in sub-select statements contained within a TRIGGER. Ticket [4ef7e3cfca] Bug fix: Fix column default values expressions of the form "DEFAULT(-(-9223372036854775808))" so that they work correctly, initializing the column to a floating point value approximately equal to +9223372036854775808.0.

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 3.8.6: Added support for hexadecimal integer literals in the SQL parser. (Ex: 0x123abc) 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. Added the likely(X) SQL function. The unicode61 tokenizer is now included in FTS4 by default. Trigger automatic reprepares on all prepared statements when ANALYZE is run. Added a new loadable extension source code file to the source tree: fileio.c 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. Fix a column affinity problem with the IN operator. Fix the ANALYZE command so that it adds correct samples for WITHOUT ROWID tables in the sqlite_stat4 table.

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.

Changes 3.8.7.3: * Bug fix: Ensure the cached KeyInfo objects (an internal abstraction not visible to the application) do not go stale when operating in shared cache mode and frequently closing and reopening some database connections while leaving other database connections on the same shared cache open continuously. * Bug fix: Recognize that any column in the right-hand table of a LEFT JOIN can be NULL even if the column has a NOT NULL constraint. Do not apply optimizations that assume the column is never NULL.

Changes 3.7.15: * Added the sqlite3_errstr() interface. * Avoid invoking the sqlite3_trace() callback multiple times when a statement is automatically reprepared due to SQLITE_SCHEMA errors. * Added support for Windows Phone 8 platforms * Enhance IN operator processing to make use of indices with numeric affinities. * Do full-table scans using covering indices when possible, under the theory that an index will be smaller and hence can be scanned with less I/O. * Enhance the query optimizer so that ORDER BY clauses are more aggressively optimized, especially in joins where various terms of the ORDER BY clause come from separate tables of the join. * Add the ability to implement FROM clause subqueries as coroutines rather that manifesting the subquery into a temporary table. * Enhancements the command-line shell: * Added the ".print" command * Negative numbers in the ".width" command cause right-alignment * Add the ".wheretrace" command when compiled with SQLITE_DEBUG * Added the busy_timeout pragma. * Added the instr() SQL function. * Added the SQLITE_FCNTL_BUSYHANDLER file control, used to allow VFS implementations to get access to the busy handler callback. * The xDelete method in the built-in VFSes now return SQLITE_IOERR_DELETE_NOENT if the file to be deleted does not exist. * Enhanced support for QNX. * Work around an optimizer bug in the MSVC compiler when targeting ARM. * Bug fix: Avoid various concurrency problems in shared cache mode. * Bug fix: Avoid a deadlock or crash if the backup API, shared cache, and the SQLite Encryption Extension are all used at once. * Bug fix: SQL functions created using the TCL interface honor the "nullvalue" setting. * Bug fix: Fix a 32-bit overflow problem on CREATE INDEX for databases larger than 16GB. * Bug fix: Avoid segfault when using the COLLATE operator inside of a CHECK constraint or view in shared cache mode.

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.

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. ← Potentially 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. Add the SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option. Enhanced the comments that are inserted into EXPLAIN output when the SQLITE_ENABLE_EXPLAIN_COMMENTS compile-time option is enabled. Performance enhancements in the VDBE, especially to the OP_Column opcode. 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.
