<h2>SQLite Release 3.7.4 On 2010-12-07</h2><p><ol class='lessindent'>
|
|
<li> Added the <a href="../c3ref/blob_reopen.html">sqlite3_blob_reopen()</a> interface to allow an existing
|
|
<a href="../c3ref/blob.html">sqlite3_blob</a> object to be rebound to a new row.
|
|
<li> Use the new <a href="../c3ref/blob_reopen.html">sqlite3_blob_reopen()</a> interface to improve the performance
|
|
of FTS.
|
|
<li> <a href="../c3ref/vfs.html">VFSes</a> that do not support shared memory are allowed
|
|
to access <a href="../wal.html">WAL</a> databases if <a href="../pragma.html#pragma_locking_mode">PRAGMA locking_mode</a> is set to EXCLUSIVE.
|
|
<li> Enhancements to <a href="../eqp.html">EXPLAIN QUERY PLAN</a>.
|
|
<li> Added the <a href="../c3ref/stmt_readonly.html">sqlite3_stmt_readonly()</a> interface.
|
|
<li> Added <a href="../pragma.html#pragma_checkpoint_fullfsync">PRAGMA checkpoint_fullfsync</a>.
|
|
<li> Added the <a href="../c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntlfilepointer">SQLITE_FCNTL_FILE_POINTER</a> option
|
|
to <a href="../c3ref/file_control.html">sqlite3_file_control()</a>.
|
|
<li> Added support for <a href="../fts3.html#fts4">FTS4</a> and enhancements
|
|
to the FTS <a href="../fts3.html#matchinfo">matchinfo()</a> function.
|
|
<li> Added the test_superlock.c module which provides example
|
|
code for obtaining an exclusive lock to a rollback
|
|
or WAL database.
|
|
<li> Added the test_multiplex.c module which provides
|
|
an example VFS that provides multiplexing (sharding)
|
|
of a DB, splitting it over multiple files of fixed size.
|
|
<li> A <a href="http://www.sqlite.org/src/info/80ba201079">very obscure bug</a>
|
|
associated with the <a href="../optoverview.html#or_opt">or optimization</a> was fixed.
