* Added the sqlite3_create_function_v2() interface that includes a destructor
callback.
* Added support for custom r-tree queries using application-supplied callback
routines to define the boundary of the query region.
* The default page cache strives more diligently to avoid using memory beyond
what is allocated to it by SQLITE_CONFIG_PAGECACHE. Or if using page cache
is allocating from the heap, it strives to avoid going over the
sqlite3_soft_heap_limit64(), even if SQLITE_ENABLE_MEMORY_MANAGEMENT is not
set.
* Added the sqlite3_soft_heap_limit64() interface as a replacement for
sqlite3_soft_heap_limit().
* The ANALYZE command now gathers statistics on tables even if they have no
indices.
* Tweaks to the query planner to help it do a better job of finding the most
efficient query plan for each query.
* Enhanced the internal text-to-numeric conversion routines so that they work
with UTF8 or UTF16, thereby avoiding some UTF16-to-UTF8 text conversions.
* Fix a problem that was causing excess memory usage with large WAL
transactions in win32 systems.
* The interface between the VDBE and B-Tree layer is enhanced such that the
VDBE provides hints to the B-Tree layer letting the B-Tree layer know when it
is safe to use hashing instead of B-Trees for transient tables.
* Miscellaneous documentation enhancements.

* Fix an old and very obscure bug that can lead to corruption of the database
free-page list when incremental_vacuum is used.
Changes 3.7.1:
* Added new commands SQLITE_DBSTATUS_SCHEMA_USED and SQLITE_DBSTATUS_STMT_USED
to the sqlite3_db_status() interface, in order to report out the amount of
memory used to hold the schema and prepared statements of a connection.
* Increase the maximum size of a database pages from 32KiB to 64KiB.
* Use the LIKE optimization even if the right-hand side string contains no
wildcards.
* Added the SQLITE_FCNTL_CHUNK_SIZE verb to the sqlite3_file_control()
interface for both unix and windows, to cause database files to grow in
large chunks in order to reduce disk fragmentation.
* Fixed a bug in the query planner that caused performance regresssions
relative to 3.6.23.1 on some complex joins.
* Fixed a typo in the OS/2 backend.
* Refactored the pager module.
* The SQLITE_MAX_PAGE_SIZE compile-time option is now silently ignored.
The maximum page size is hard-coded at 65536 bytes.
|
|
* Fix a potential database corruption problem that can result if the same
database file is alternately written by version 3.7.0 and 3.6.23.1.
* Fix a possible performance regression caused by the introduction of automatic
indexing.
|
|
* Added support for write-ahead logging.
* Query planner enhancement - automatic transient indices are created when
doing so reduces the estimated query time.
* Query planner enhancement - the ORDER BY becomes a no-op if the query also
contains a GROUP BY clause that forces the correct output order.
* Add the SQLITE_DBSTATUS_CACHE_USED verb for sqlite3_db_status().
* The logical database size is now stored in the database header so that bytes
can be appended to the end of the database file without corrupting it and so
that SQLite will work correctly on systems that lack support for ftruncate().

way to build sqlite3 according to upstream.
It should give a small performance increase due to static inlining,
but more importantly lets us avoid manual maintenance of sqlite3.h.
Bump revisions for sqlite3 and sqlite3-tcl.
|
|
* Optimizer enhancement: prepared statements are automatically re-compiled when
a binding on the RHS of a LIKE operator changes or when any range constraint
changes under SQLITE_ENABLE_STAT2.
* Various minor bug fixes and documentation enhancements.
|
|
Makefile: bump
Makefile.common: document why this needs to be done
|
|
* Added support for foreign key constraints. Foreign key constraints are
disabled by default. Use the foreign_keys pragma to turn them on.
* Generalized the IS and IS NOT operators to take arbitrary expressions on
their right-hand side.
* The TCL Interface has been enhanced to use the Non-Recursive Engine (NRE)
interface to the TCL interpreter when linked against TCL 8.6 or later.
* Fix a bug introduced in 3.6.18 that can lead to a segfault when an attempt
is made to write on a read-only database.

* Versioning of the SQLite source code has transitioned from CVS to Fossil.
* Query planner enhancements.
* The SQLITE_ENABLE_STAT2 compile-time option causes the ANALYZE command to
collect a small histogram of each index, to help SQLite better select among
competing range query indices.
* Recursive triggers can be enabled using the PRAGMA recursive_triggers
statement.
* Delete triggers fire when rows are removed due to a REPLACE conflict
resolution. This feature is only enabled when recursive triggers are enabled.
* Added the SQLITE_OPEN_SHAREDCACHE and SQLITE_OPEN_PRIVATECACHE flags for
sqlite3_open_v2() used to override the global shared cache mode settings for
individual database connections.
* Added improved version identification features: C-Preprocessor macro
SQLITE_SOURCE_ID, C/C++ interface sqlite3_sourceid(), and SQL function
sqlite_source_id().
* Obscure bug fix on triggers
|
|
* Expose the sqlite3_strnicmp() interface for use by extensions and
applications.
* Remove the restriction on virtual tables and shared cache mode. Virtual
tables and shared cache can now be used at the same time.
* Many code simplifications and obscure bug fixes in support of providing 100%
branch test coverage.

* Enhanced the query optimizer so that virtual tables are able to make use of
OR and IN operators in the WHERE clause.
* Speed improvements in the btree and pager layers.

This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

(Please give the pkgs you commit a least a minimal testing. Since
sqlite3-tcl is needed to run the sqlite selftests the least I'd expect
is to build that as well.)
|
|
Also set ac_cv_prog_TCLSH_CMD="" so the configure script won't find tcl.
|
|
* Added the hot-backup interface.
* Added new commands ".backup" and ".restore" to the CLI.
* Added new methods backup and restore to the TCL interface.

* Various minor bug fixes
|
|
|
|
* Fix a cache coherency problem that could lead to database corruption.
|
|
* Fix two bugs, which when combined might result in incorrect query results.
Both bugs were harmless by themselves; only when they team up do they cause
problems.
Changes 3.6.8:
* Added support for nested transactions.
* Enhanced the query optimizer so that it is able to use multiple indices
to efficiently process OR-connected constraints in a WHERE clause.
* Added support for parentheses in FTS3 query patterns using
the SQLITE_ENABLE_FTS3_PARENTHESIS compile-time option.

* Reorganize the Unix interface in os_unix.c
* Added support for "Proxy Locking" on MacOSX.
* Changed the prototype of the sqlite3_auto_extension() interface in a way
that is backwards compatible but which might cause warnings in new
builds of applications that use that interface.
* Changed the signature of the xDlSym method of the sqlite3_vfs object in
a way that is backwards compatible but which might cause compiler
warnings.
* Added superfluous casts and variable initializations in order to
suppress nuisance compiler warnings.
* Fixes for various minor bugs.

an attempt is made to ROLLBACK while one or more queries are still pending.
* Drop all support for the experimental memory allocators memsys4 and memsys6.
* Added the SQLITE_ZERO_MALLOC compile-time option.

licenses yet. Noticed By smb@.
|
|

load-extension these days. OKed by wiz to commit.
Bump PKGREVISION.
|
|
* Split the pager subsystem into separate pager and pcache subsystems.
* Factor out indentifier resolution procedures into separate files.
* Bug fixes.
|
|
* Added the lookaside memory allocator for a speed improvement in excess of 15%
on some workloads. (Your mileage may vary.)
* Added the SQLITE_CONFIG_LOOKASIDE verb to sqlite3_config() to control the
default lookaside configuration.
* Added verbs SQLITE_STATUS_PAGECACHE_SIZE and SQLITE_STATUS_SCRATCH_SIZE to
the sqlite3_status() interface.
* Modified SQLITE_CONFIG_PAGECACHE and SQLITE_CONFIG_SCRATCH to remove the "+4"
magic number in the buffer size computation.
* Added the sqlite3_db_config() and sqlite3_db_status() interfaces for
controlling and monitoring the lookaside allocator separately on each
database connection.
* Numerious other performance enhancements
* Miscellaneous minor bug fixes
|
|
* Modifications to the virtual file system interface to support a wider range
of embedded systems.
* All C-preprocessor macros used to control compile-time options now begin
with the prefix "SQLITE_".
* The SQLITE_MUTEX_APPDEF compile-time option is no longer supported.
* The handling of IN and NOT IN operators that contain a NULL on their
right-hand side expression is brought into compliance with the SQL standard
and with other SQL database engines. This is a bug fix, but as it has the
potential to break legacy applications that depend on the older buggy
behavior.
* The result column names generated for compound subqueries have been
simplified to show only the name of the column of the original table and
omit the table name. This makes SQLite operate more like other SQL database
engines.
* Added the sqlite3_config() interface for doing run-time configuration of the
entire SQLite library.
* Added the sqlite3_status() interface used for querying run-time status
information about the overall SQLite library and its subsystems.
* Added the sqlite3_initialize() and sqlite3_shutdown() interfaces.
* The SQLITE_OPEN_NOMUTEX option was added to sqlite3_open_v2().
* Added the PRAGMA page_count command.
* Added the sqlite3_next_stmt() interface.
* Added a new R*Tree virtual table
