<h2>SQLite Release 3.13.0 On 2016-05-18</h2><p><ol class='lessindent'>
|
|
<li>Postpone I/O associated with TEMP files for as long as possible, with the hope
|
|
that the I/O can ultimately be avoided completely.
|
|
<li>Merged the <a href="../sessionintro.html">session</a> extension into trunk.
|
|
<li>Added the ".auth ON|OFF" command to the <a href="../cli.html">command-line shell</a>.
|
|
<li>Added the "--indent" option to the ".schema" and ".fullschema" commands of
|
|
the <a href="../cli.html">command-line shell</a>, to turn on pretty-printing.
|
|
<li>Added the ".eqp full" option to the <a href="../cli.html">command-line shell</a>, that does both <a href="../lang_explain.html">EXPLAIN</a>
|
|
and <a href="../eqp.html">EXPLAIN QUERY PLAN</a> on each statement that is evaluated.
|
|
<li>Improved unicode filename handling in the <a href="../cli.html">command-line shell</a> on Windows.
|
|
<li>Improved resistance against goofy query planner decisions caused by
|
|
incomplete or incorrect modifications to the <a href="../fileformat2.html#stat1tab">sqlite_stat1</a>
|
|
table by the application.
|
|
<li>Added the <a href="../c3ref/db_config.html">sqlite3_db_config</a>(db,<a href="../c3ref/c_dbconfig_defensive.html#sqlitedbconfigenableloadextension">SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION</a>) interface
|
|
which allows the <a href="../c3ref/load_extension.html">sqlite3_load_extension()</a> C-API to be enabled while keeping the
|
|
<a href="../lang_corefunc.html#load_extension">load_extension()</a> SQL function disabled for security.
|
|
<li>Change the <a href="../tempfiles.html#tempdir">temporary directory search algorithm</a> on Unix to allow directories with
|
|
write and execute permission, but without read permission, to serve as temporary
|
|
directories. Apply this same standard to the "." fallback directory.
|
|
<p><b>Bug Fixes:</b>
|
|
<li>Fix a problem with the multi-row one-pass DELETE optimization that was
|
|
causing it to compute incorrect answers with a self-referential subquery in
|
|
the WHERE clause. Fix for ticket
|
|
<a href="https://www.sqlite.org/src/info/dc6ebeda9396087">dc6ebeda9396087</a>
|
|
<li>Fix a possible segfault with DELETE when table is a <a href="../rowidtable.html">rowid table</a> with an
|
|
<a href="../lang_createtable.html#rowid">INTEGER PRIMARY KEY</a> and the WHERE clause contains a OR and
|
|
the table has one or more indexes that are able to trigger the OR optimization,
|
|
but none of the indexes reference any table columns other than the INTEGER PRIMARY KEY.
|
|
Ticket <a href="https://www.sqlite.org/src/info/16c9801ceba49">16c9801ceba49</a>.
|
|
<li>When checking for the WHERE-clause push-down optimization, verify that all terms
|
|
of the compound inner SELECT are non-aggregate, not just the last term. Fix for ticket
|
|
<a href="https://www.sqlite.org/src/info/f7f8c97e97597">f7f8c97e97597</a>.
|
|
<li>Fix a locking race condition in Windows that can occur when two or more processes
|
|
attempt to recover the same <a href="../fileformat2.html#hotjrnl">hot journal</a> at the same time.

|
|
|
<p><b>Bug fixes backported into patch release 3.12.2 (2016-04-18):</b></p>
|
|
|
|
<li>Fix a backwards compatibility problem in version 3.12.0 and 3.12.1:
|
|
Columns declared as <tt>"INTEGER" PRIMARY KEY</tt> (with quotes around
|
|
the datatype keyword) were not being recognized as an
|
|
<a href="../lang_createtable.html#rowid">INTEGER PRIMARY KEY</a>, which resulted in an incompatible database file.
|
|
Ticket <a href="https://www.sqlite.org/src/info/7d7525cb01b68">7d7525cb01b68</a>
|
|
<li>Fix a bug (present since <a href="../releaselog/3_9_0.html">version 3.9.0</a>) that can cause the <a href="../lang_delete.html">DELETE</a>
|
|
operation to miss rows if <a href="../pragma.html#pragma_reverse_unordered_selects">PRAGMA reverse_unordered_selects</a> is turned on.
|
|
Ticket <a href="https://www.sqlite.org/src/info/a306e56ff68b8fa5">a306e56ff68b8fa5</a>
|
|
<li>Fix a bug in the code generator that can cause incorrect results if
|
|
two or more <a href="../vtab.html">virtual tables</a> are joined and the virtual table used in
|
|
outer loop of the join has an <a href="../lang_expr.html#in_op">IN operator</a> constraint.
|
|
<li>Correctly interpret negative "PRAGMA cache_size" values when determining
|
|
the cache size used for sorting large amounts of data.
|
|
|
|
<p><b>Bug fixes backported into patch release 3.12.1 (2016-04-08):</b></p>
|
|
|
|
<li>Fix a boundary condition error introduced by version 3.12.0
|
|
that can result in a crash during heavy <a href="../lang_savepoint.html">SAVEPOINT</a> usage.
|
|
Ticket <a href="https://www.sqlite.org/src/info/7f7f8026eda38">7f7f8026eda38</a>.
|
|
<li>Fix <a href="../lang_createview.html">views</a> so that they inherit column datatypes from the
|
|
table that they are defined against, when possible.
|
|
<li>Fix the query planner so that IS and IS NULL operators are able
|
|
to drive an index on a LEFT OUTER JOIN.
