* 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
* Added experimental support for the journal_mode PRAGMA and persistent
journal.
* Journal mode PERSIST is the default behavior in exclusive locking mode.
* Fix a performance regression on LEFT JOIN (see ticket #3015) that was
mistakenly introduced in version 3.5.8.
* Performance enhancement: Reengineer the internal routines used to
interpret and render variable-length integers.
* Fix a buffer-overrun problem in sqlite3_mprintf() which occurs when
a string without a zero-terminator is passed to "%.*s".
* Always convert IEEE floating point NaN values into NULL during
processing.
* Make sure that when a connection blocks on a RESERVED lock that it is
able to continue after the lock is released.
* The "configure" scripts should now automatically configure unix systems
for large file support. Improved error messages for when large files are
encountered and large file support is disabled.
* Avoid cache pages leaks following disk-full or I/O errors
* And, many more minor bug fixes and performance enhancements...
2008 Feb 6 (3.5.6)
* Fix a bug ( ticket #2913) that prevented virtual tables from working
in a LEFT JOIN. The problem was introduced into shortly before the
3.5.5 release.
* Bring the OS/2 porting layer up-to-date.
* Add the new sqlite3_result_error_code() API and use it in the
implementation of ATTACH so that proper error codes are returned when
an ATTACH fails.
2008 Jan 31 (3.5.5)
* Convert the underlying virtual machine to be a register-based machine
rather than a stack-based machine. The only user-visible change is in
the output of EXPLAIN.
* Add the build-in RTRIM collating sequence.
2007 Dec 14 (3.5.4)
* Fix a critical bug in UPDATE or DELETE that occurs when an OR REPLACE
clause or a trigger causes rows in the same table to be deleted as
side effects. (See ticket #2832.) The most likely result of this bug
is a segmentation fault, though database corruption is a possibility.
* Bring the processing of ORDER BY into compliance with the SQL standard
for case where a result alias and a table column name are in conflict.
Correct behavior is to prefer the result alias. Older versions of
SQLite incorrectly picked the table column. (See ticket #2822.)
* The VACUUM command preserves the setting of the legacy_file_format
pragma. ( Ticket #2804.)
* Productize and officially support the group_concat() SQL function.
* Better optimization of some IN operator expressions.
* Add the ability to change the auto_vacuum status of a database by
setting the auto_vaccum pragma and VACUUMing the database.
* Prefix search in FTS3 is much more efficient.
* Relax the SQL statement length restriction in the CLI so that the
".dump" output of databases with very large BLOBs and strings can be
played back to recreate the database.
* Other small bug fixes and optimizations.
2007 Nov 27 (3.5.3)
* Move website and documentation files out of the source tree into a
separate CM system.
* Fix a long-standing bug in INSERT INTO ... SELECT ... statements where
the SELECT is compound.
* Fix a long-standing bug in RAISE(IGNORE) as used in BEFORE triggers.
* Fixed the operator precedence for the ~ operator.
* On win32, do not return an error when attempting to delete a file that
does not exist.
* Allow collating sequence names to be quoted.
* Modify the TCL interface to use sqlite3_prepare_v2().
* Fix multiple bugs that can occur following a malloc() failure.
* sqlite3_step() returns SQLITE_MISUSE instead of crashing when called
with a NULL parameter.
* FTS3 now uses the SQLite memory allocator exclusively. The FTS3
amalgamation can now be appended to the SQLite amalgamation to
generate a super-amalgamation containing both.
* The DISTINCT keyword now will sometimes use an INDEX if an appropriate
index is available and the optimizer thinks its use might be
advantageous.
the file lemon.c uses the same identifiers (B_TRUE, B_FALSE) as the
<sys/types.h> header, and therefore fails to build.
Changes since 3.4.2:
2007 Nov 05 (3.5.2)
* Dropped support for the SQLITE_OMIT_MEMORY_ALLOCATION compile-time
option.
* Always open files using FILE_FLAG_RANDOM_ACCESS under windows.
* The 3rd parameter of the built-in SUBSTR() function is now
optional.
* Bug fix: do not invoke the authorizer when reparsing the schema
after a schema change.
* Added the experimental malloc-free memory allocator in mem3.c.
* Virtual machine stores 64-bit integer and floating point constants
in binary instead of text for a performance boost.
* Fix a race condition in test_async.c.
* Added the ".timer" command to the CLI
2007 Oct 04 (3.5.1)
* Nota Bene: We are not using terms "alpha" or "beta" on this release
because the code is stable and because if we use those terms,
nobody will upgrade. However, we still reserve the right to make
incompatible changes to the new VFS interface in future releases.
* Fix a bug in the handling of SQLITE_FULL errors that could lead to
database corruption. [11]Ticket #2686.
* The test_async.c drive now does full file locking and works
correctly when used simultaneously by multiple processes on the
same database.
* The CLI ignores whitespace (including comments) at the end of lines
* Make sure the query optimizer checks dependences on all terms of a
compound SELECT statement. [12]Ticket #2640.
* Add demonstration code showing how to build a VFS for a raw mass
storage without a filesystem.
* Added an output buffer size parameter to the xGetTempname() method
of the VFS layer.
* Sticky SQLITE_FULL or SQLITE_IOERR errors in the pager are reset
when a new transaction is started.
2007 Sep 04 (3.5.0) alpha
* Redesign the OS interface layer. See [13]34to35.html for details.
*** Potentially incompatible change ***
* The [14]sqlite3_release_memory(), [15]sqlite3_soft_heap_limit(),
and [16]sqlite3_enable_shared_cache() interfaces now work cross all
threads in the process, not just the single thread in which they
are invoked. *** Potentially incompatible change ***
* Added the [17]sqlite3_open_v2() interface.
* Reimplemented the memory allocation subsystem and made it
replacable at compile-time.
* Created a new mutex subsystem and made it replacable at
compile-time.
* The same database connection may now be used simultaneously by
separate threads.
While stress-testing the soft_heap_limit feature, a bug that could
lead to database corruption was discovered and fixed. Though the
consequences of this bug are severe, the chances of hitting it in
a typical application are remote. Upgrading is recommended only if
you use the sqlite3_soft_heap_limit interface.
This release fixes a bug in VACUUM that can lead to database
corruption. The bug was introduced in version 3.3.14. Upgrading is
recommended for all users. Also included are a slew of other more
routine enhancements and bug fixes.
pkgsrc note: 3 selftests are failing due to some loss of accuracy
in floating point calculations. The upstream fix is to disable the
selftests in question (see sqlite ticket #2570).
2007 June 18 (3.4.0)
* Fix a bug that can lead to database corruption if an SQLITE_BUSY
error occurs in the middle of an explicit transaction and that
transaction is later committed. Ticket #2409. See the
CorruptionFollowingBusyError wiki page for details.
* Fix a bug that can lead to database corruption if autovacuum mode
is on and a malloc() failure follows a CREATE TABLE or CREATE INDEX
statement which itself follows a cache overflow inside a transaction.
See ticket #2418.
* Added explicit upper bounds on the sizes and quantities of things
SQLite can process. This change might cause compatibility problems
for applications that use SQLite in the extreme, which is why the
current release is 3.4.0 instead of 3.3.18.
* Added support for Incremental BLOB I/O.
* Added the zeroblob API and the zeroblob() SQL function.
* Added support for Incremental Vacuum.
* Added the SQLITE_MIXED_ENDIAN_64BIT_FLOAT compile-time option to
suppport ARM7 processors with goofy endianness.
* Removed all instances of sprintf() and strcpy() from the core
library.
* Added support for International Components for Unicode (ICU) to
the full-text search extensions.
* In the windows OS driver, reacquire a SHARED lock if an attempt
to acquire an EXCLUSIVE lock fails. Ticket #2354
* Fix the REPLACE() function so that it returns NULL if the second
argument is an empty string. Ticket #2324.
* Document the hazards of type coversions in sqlite3_column_blob()
and related APIs. Fix unnecessary type conversions. Ticket #2321.
* Internationalization of the TRIM() function. Ticket #2323
* Use memmove() instead of memcpy() when moving between memory
regions that might overlap. Ticket #2334
* Fix an optimizer bug involving subqueries in a compound SELECT
that has both an ORDER BY and a LIMIT clause. Ticket #2339.
* Make sure the sqlite3_snprintf() interface does not zero-terminate
the buffer if the buffer size is less than 1. Ticket #2341
* Fix the built-in printf logic so that it prints "NaN" not "Inf"
for floating-point NaNs. Ticket #2345
* When converting BLOB to TEXT, use the text encoding of the main
database. Ticket #2349
* Keep the full precision of integers (if possible) when casting
to NUMERIC. Ticket #2364
* Fix a bug in the handling of UTF16 codepoint 0xE000
* Consider explicit collate clauses when matching WHERE constraints
to indices in the query optimizer. Ticket #2391
* Fix the query optimizer to correctly handle constant expressions
in the ON clause of a LEFT JOIN. Ticket #2403
* Fix the query optimizer to handle rowid comparisions to NULL
correctly. Ticket #2404
* Fix many potental segfaults that could be caused by malicious
SQL statements.
2007 April 25 (3.3.17)
* When the "write_version" value of the database
header is larger than what the library understands,
make the database read-only instead of unreadable.
* Other minor bug fixes
2007 April 18 (3.3.16)
* Fix a bug that caused VACUUM to fail if NULLs
appeared in a UNIQUE column.
* Reinstate performance improvements that were added
in 3.3.14 but regressed in 3.3.15.
* Fix problems with the handling of ORDER BY expressions
on compound SELECT statements in subqueries.
* Fix a potential segfault when destroying locks on
WinCE in a multi-threaded environment.
* Documentation updates.
2007 April 9 (3.3.15)
* Fix a bug introduced in 3.3.14 that caused a rollback
of CREATE TEMP TABLE to leave the database connection
wedged.
* Fix a bug that caused an extra NULL row to be
returned when a descending query was interrupted by
a change to the database.
* The FOR EACH STATEMENT clause on a trigger now
causes a syntax error. It used to be silently ignored.
* Fix an obscure and relatively harmless problem that
might have caused a resource leak following an I/O
error.
* Many improvements to the test suite. Test coverage
now exceeded 98%
2007 April 2 (3.3.14)
* Fix a bug in 3.3.13 that could cause a segfault
when the IN operator is used one one term of a
two-column index and the right-hand side of the IN
operator contains a NULL.
* Added a new OS interface method for determining
the sector size of underlying media: sqlite3OsSectorSize().
* A new algorithm for statements of the form INSERT
INTO table1 SELECT * FROM table2 is faster and
reduces fragmentation. VACUUM uses statements of
this form and thus runs faster and defragments
better.
* Performance enhancements through reductions in disk I/O:
* Do not read the last page of an overflow chain
when deleting the row - just add that page to
the freelist.
* Do not store pages being deleted in the rollback journal.
* Do not read in the (meaningless) content of
pages extracted from the freelist.
* Do not flush the page cache (and thus avoiding
a cache refill) unless another process changes
the underlying database file.
* Truncate rather than delete the rollback
journal when committing a transaction in
exclusive access mode, or when committing the
TEMP database.
* Added support for exclusive access mode using
"PRAGMA locking_mode=EXCLUSIVE"
* Use heap space instead of stack space for large
buffers in the pager - useful on embedded platforms
with stack-space limitations.
* Add a makefile target "sqlite3.c" that builds an
amalgamation containing the core SQLite library C
code in a single file.
* Get the library working correctly when compiled
with GCC option "-fstrict-aliasing".
* Removed the vestigal SQLITE_PROTOCOL error.
* Improvements to test coverage, other minor bugs
fixed, memory leaks plugged, code refactored and/or
recommented in places for easier reading.
changes:
-fixed bugs which can lead to database corruption under obscure and
difficult to reproduce circumstances
-new sqlite3_prepare_v2() API
-bug fixes in the command-line shell
-enhancements to the query optimizer
pkgsrc change: fix a selftest which couldn't work as intended due to
misuse of O_APPEND
Version 3.3.8 adds support for full-text search using the FTS1
module. There are also minor bug fixes. Upgrade only if you want
to try out the new full-text search capabilities or if you are
having problems with 3.3.7.
Version 3.3.7 includes support for loadable extensions and virtual
tables. But both features are still considered "beta" and their
APIs are subject to change in a future release. This release is
mostly to make available the minor bug fixes that have accumulated
since 3.3.6. Upgrading is not necessary. Do so only if you encounter
one of the obscure bugs that have been fixed or if you want to try
out the new features.
2006-Jun-6 - Version 3.3.6
Changes include improved tolerance for windows virus scanners and
faster :memory: databases. There are also fixes for several obscure
bugs. Upgrade if you are having problems.
2006-Apr-5 - Version 3.3.5
This release fixes many minor bugs and documentation typos and
provides some minor new features and performance enhancements.
Upgrade only if you are having problems or need one of the new
features.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
changes:
adds support for CHECK constraints, DESC indices, separate
REAL and INTEGER column affinities, a new OS interface layer design, and
many other changes
pkgsrc note:
a selftest fails on NetBSD/i386: a loss of precision is not detected in
the sum() function. Reason is that the code assumes that a "long double"
keeps more significant bits than a "long long int" which is not true here.
This is not a regression to 3.2.x which did just wrap on int overflows.
2005 September 24 (3.2.7)
* GROUP BY now considers NULLs to be equal again, as it should
* Now compiles on Solaris and OpenBSD and other Unix variants that lack the
fdatasync() function
* Now compiles on MSVC++6 again
* Fix uninitialized variables causing malfunctions for various obscure queries
* Correctly compute a LEFT OUTER JOINs that is constrained on the left table only
2005 September 17 (3.2.6)
* Fix a bug that can cause database corruption if a VACUUM (or autovacuum) fails
and is rolled back on a database that is larger than 1GiB
* LIKE optiization now works for columns with COLLATE NOCASE
* ORDER BY and GROUP BY now use bounded memory
* Added support for COUNT(DISTINCT expr)
* Change the way SUM() handles NULL values in order to comply with the SQL standard
* Use fdatasync() instead of fsync() where possible in order to speed up commits
slightly
* Use of the CROSS keyword in a join turns off the table reordering optimization
* Added the experimental and undocumented EXPLAIN QUERY PLAN capability
* Use the unicode API in windows
2005 August 27 (3.2.5)
* Fix a bug effecting DELETE and UPDATE statements that changed more than 40960
rows.
* Change the makefile so that it no longer requires GNUmake extensions
* Fix the --enable-threadsafe option on the configure script
* Fix a code generator bug that occurs when the left-hand side of an IN operator is
constant and the right-hand side is a SELECT statement
* The PRAGMA synchronous=off statement now disables syncing of the master journal
file in addition to the normal rollback journals
2005 August 24 (3.2.4)
* Fix a bug introduced in the previous release that can cause a segfault while
generating code for complex WHERE clauses.
* Allow floating point literals to begin or end with a decimal point.
2005 August 21 (3.2.3)
* Added support for the CAST operator
* Tcl interface allows BLOB values to be transferred to user-defined functions
* Added the "transaction" method to the Tcl interface
* Allow the DEFAULT value of a column to call functions that have constant operands
* Added the ANALYZE command for gathering statistics on indices and using those
statistics when picking an index in the optimizer
* Remove the limit (formerly 100) on the number of terms in the WHERE clause
* The right-hand side of the IN operator can now be a list of expressions instead
of just a list of constants
* Rework the optimizer so that it is able to make better use of indices
* The order of tables in a join is adjusted automatically to make better use of
indices
* The IN operator is now a candidate for optimization even if the left-hand side is
not the left-most term of the index. Multiple IN operators can be used with the
same index.
* WHERE clause expressions using BETWEEN and OR are now candidates for optimization
* Added the "case_sensitive_like" pragma and the SQLITE_CASE_SENSITIVE_LIKE
compile-time option to set its default value to "on".
* Use indices to help with GLOB expressions and LIKE expressions too when the
case_sensitive_like pragma is enabled
* Added support for grave-accent quoting for compatibility with MySQL
* Improved test coverage
from the announcement:
This release includes numerous minor bug fixes, speed improvements, and
code size reductions. There is no reason to upgrade unless you are having
problems or unless you just want to.
2005 March 29 (3.2.1)
* Fix a memory allocation error in the new ADD COLUMN comment.
* Documentation updates
2005 March 21 (3.2.0)
* Added support for ALTER TABLE ADD COLUMN.
* Added support for the "T" separator in ISO-8601 date/time strings.
* Improved support for Cygwin.
* Numerous bug fixes and documentation updates.
2005 March 16 (3.1.6)
* Fix a bug that could cause database corruption when inserting
record into tables with around 125 columns.
* sqlite3_step() is now much more likely to invoke the busy
handler and less likely to return SQLITE_BUSY.
* Fix memory leaks that used to occur after a malloc() failure.
2005 March 11 (3.1.5)
* The ioctl on OS-X to control syncing to disk is F_FULLFSYNC,
not F_FULLSYNC. The previous release had it wrong.
2005 March 10 (3.1.4)
* Fix a bug in autovacuum that could cause database corruption
if a CREATE UNIQUE INDEX fails because of a constraint violation.
This problem only occurs if the new autovacuum feature introduced
in version 3.1 is turned on.
* The F_FULLSYNC ioctl (currently only supported on OS-X) is
disabled if the synchronous pragma is set to something other
than "full".
* Add additional forward compatibility to the future version 3.2
database file format.
* Fix a bug in WHERE clauses of the form (rowid<'2')
* New SQLITE_OMIT_... compile-time options added
* Updates to the man page
* Remove the use of strcasecmp() from the shell
* Windows DLL exports symbols Tclsqlite_Init and Sqlite_Init
addition of the new sqlite3-tcl package. The TCL bindings can be easily
built and installed independently, so it's better to have an standalone
package rather than a build-time option.
While here, fix PKGCONFIG_OVERRIDE and bump PKGREVISION to 2.
2005 February 19 (3.1.3)
* Fix a problem with VACUUM on databases from which tables containing AUTOINCREMENT
have been dropped.
* Add forward compatibility to the future version 3.2 database file format.
* Documentation updates

* Other minor bug fixes and performance enhancements.
2005 February 1 (3.1.1 BETA)
* Automatic caching of prepared statements in the TCL interface
* ATTACH and DETACH as well as some other operations cause existing prepared
statements to expire.
* Numerious minor bug fixes
2005 January 21 (3.1.0 ALPHA)
* Autovacuum support added
* CURRENT_TIME, CURRENT_DATE, and CURRENT_TIMESTAMP added
* Support for the EXISTS clause added.
* Support for correlated subqueries added.
* Added the ESCAPE clause on the LIKE operator.

needs from an index.
* Many nuisance bugs fixed.
with sqlite version 2 (everything in this package ends in `3'). DESCR:
SQLite is a C library that implements an SQL database engine. Programs
that link with the SQLite library can have SQL database access without
running a separate RDBMS process. The distribution comes with a standalone
command-line access program (sqlite) that can be used to administer an
SQLite database and which serves as an example of how to use the SQLite
library.
SQLite is not a client library used to connect to a big database server.
SQLite is the server. The SQLite library reads and writes directly to and
from the database files on disk.
