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.
===> Building for sqlite3-3.6.18
tclsh ./tool/mksqlite3h.tcl . >sqlite3.h

gmake: *** [sqlite3.h] Error 127
Upstream didn't ship a pregenerated sqlite3.h. Committed as patch-ab.
* Fixed a bug that caused database corruption when an incremental vacuum is
rolled back in an in-memory database.
* Added the sqlite3_unlock_notify() interface.
* Added the reverse unordered selects pragma.
* The default page size on windows is automatically adjusted to match the
capabilities of the underlying filesystem.
* Add the new ".genfkey" command in the CLI for generating triggers to
implement foreign key constraints.
* Performance improvements for "count(*)" queries.
* Reduce the amount of heap memory used, especially by TRIGGERs.
(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.)
* Added the hot-backup interface.
* Added new commands ".backup" and ".restore" to the CLI.
* Added new methods backup and restore to the TCL interface.
* Improvements to the syntax bubble diagrams
* Various minor bug fixes
* 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...
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.
