<h2>SQLite Release 3.15.1 On 2016-11-04</h2><p><b>Changes in version 3.15.0 (2016-10-14):</b></p>
|
|
<p><ol class='lessindent'>
|
|
<li value='1'> Added support for <a href="../rowvalue.html">row values</a>.
|
|
<li> Allow <a href="../deterministic.html">deterministic SQL functions</a> in the WHERE clause of a <a href="../partialindex.html">partial index</a>.
|
|
<li> Added the "<a href="../uri.html#urimodeof">modeof=<i>filename</i></a>" URI parameter on the unix VFS
|
|
<li> Added support for <a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigmaindbname">SQLITE_DBCONFIG_MAINDBNAME</a>.
|
|
<li> Added the ability to <a href="../lang_vacuum.html">VACUUM</a> an <a href="../lang_attach.html">ATTACH-ed</a> database.
|
|
<li> Enhancements to the <a href="../cli.html">command-line shell</a>:
|
|
<ol type='a'>
|
|
<li> Add the ".testcase" and ".check" <a href="../cli.html#dotcmd">dot-commands</a>.
|
|
<li> Added the --new option to the ".open" dot-command, causing
|
|
any prior content in the database to be purged prior to
|
|
opening.
|
|
</ol>
|
|
<li> Enhance the <a href="../fts5.html#the_fts5vocab_virtual_table_module">fts5vocab</a> virtual table to handle "ORDER BY term" efficiently.
|
|
<li> Miscellaneous micro-optimizations reduce CPU usage by more than 7%
|
|
on common workloads. Most optimization in this release has been on the
|
|
front-end (<a href="../c3ref/prepare.html">sqlite3_prepare_v2()</a>).
|
|
<p><b>Bug Fixes:</b>
|
|
<li> The multiply operator now correctly detects 64-bit integer overflow
|
|
and promotes to floating point in all corner-cases. Fix for ticket
|
|
<a href="https://www.sqlite.org/src/info/1ec41379c9c1e400">1ec41379c9c1e400</a>.
|
|
<li> Correct handling of columns with redundant unique indexes when those
|
|
columns are used on the LHS of an <a href="../lang_expr.html#in_op">IN operator</a>. Fix for ticket
|
|
<a href="https://www.sqlite.org/src/info/0eab1ac759">0eab1ac759</a>.
|
|
<li> Skip NULL entries on range queries in <a href="../expridx.html">indexes on expressions</a>.
|
|
Fix for ticket
|
|
<a href="https://www.sqlite.org/src/tktview/4baa46491212947">4baa46491212947</a>.
|
|
<li> Ensure that the <a href="../autoinc.html">AUTOINCREMENT</a> counters in the sqlite_sequence
|
|
table are initialized doing "Xfer Optimization" on "INSERT ... SELECT"
|
|
statements. Fix for ticket
|
|
<a href="https://www.sqlite.org/src/info/7b3328086a5c116c">7b3328086a5c116c</a>.
|
|
<li> Make sure the ORDER BY LIMIT optimization
|
|
(from check-in <a href="https://www.sqlite.org/src/info/559733b09e9630fa">559733b09e</a>)
|
|
works with IN operators on INTEGER PRIMARY KEYs. Fix for ticket
|
|
<a href="https://www.sqlite.org/src/info/96c1454cbfd9509">96c1454c</a>
|
|
</ol>
|
|
<p><b>Additional changes in version 3.15.1:</b></p>
|
|
<p><ol class='lessindent'>
|
|
<li value='14'> Added <a href="../c3ref/c_fcntl_begin_atomic_write.html#sqlitefcntlwin32gethandle">SQLITE_FCNTL_WIN32_GET_HANDLE</a> file control opcode.
|
|
<li> Fix the <a href="../lang_vacuum.html">VACUUM</a> command so that it spills excess content to disk rather
|
|
than holding everything in memory, and possible causing an out-of-memory
|
|
error for larger database files. This fixes an issue introduced by
|
|
version 3.15.0.
|
|
<li> Fix a case (present since 3.8.0 - 2013-08-26)
|
|
where OR-connected terms in the ON clause of a LEFT JOIN
|
|
might cause incorrect results. Ticket
|
|
<a href="https://www.sqlite.org/src/info/34a579141b2c5ac">34a579141b2c5ac</a>.
|
|
<li> Fix a case where the use of <a href="../rowvalue.html">row values</a> in the ON clause of a LEFT JOIN
|
|
might cause incorrect results. Ticket
|
|
<a href="https://www.sqlite.org/src/info/fef4bb4bd9185ec8f">fef4bb4bd9185ec8f</a>.
