<h2>3.13.0-r1<a class="headerlink" href="#r1" title="Permalink to this headline">¶</a></h2>
<p>Added SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION constant.</p>
<p>Added a <a class="reference internal" href="download.html#really-want-pip"><span>pip command line</span></a> in the <a class="reference internal" href="download.html"><em>Download</em></a> page.</p>

<div class="section" id="id1">
<h2>3.12.2-r1<a class="headerlink" href="#id1" title="Permalink to this headline">¶</a></h2>
<p>Call <a class="reference external" href="https://www.python.org/dev/peps/pep-0393/#new-api">PyUnicode_READY</a> for
Python 3.3 onwards. Fixes <a class="reference external" href="https://github.com/rogerbinns/apsw/issues/208">APSW issue 208</a>, <a class="reference external" href="https://github.com/rogerbinns/apsw/issues/132">APSW issue 132</a>, <a class="reference external" href="https://github.com/rogerbinns/apsw/issues/168">APSW issue 168</a>.</p>
<p>SQLite 3.12 completely changed the semantics of <a class="reference internal" href="vfs.html#apsw.VFS.xGetLastError" title="apsw.VFS.xGetLastError"><code class="xref py py-meth docutils literal"><span class="pre">VFS.xGetLastError()</span></code></a> in an
incompatible way. This required a rewrite of the relevant C, Python and test
code. If you implement or use this method then you have to rewrite your code
too. Also note that running the test suite from an earlier version of APSW
against this or future SQLite versions will result in consuming all memory, swap
or address space (an underlying integer changed meaning).</p>
<p>Added SQLITE_CONFIG_STMTJRNL_SPILL and SQLITE_DBCONFIG_ENABLE_FTS3_TOKENIZER
constants.</p>
<p>Added support for SQLITE_CONFIG_STMTJRNL_SPILL in <a class="reference internal" href="apsw.html#apsw.config" title="apsw.config"><code class="xref py py-meth docutils literal"><span class="pre">apsw.config()</span></code></a>.</p>

<p>setup.py attempts to use setuptools if present, before falling back to
distutils. This allows setuptools only commands such as bdist_wheel to work. You
can force use of distutils by setting the environment variable
APSW_FORCE_DISTUTILS to any value. Note that setuptools may also affect the
output file names. (<a class="reference external" href="https://github.com/rogerbinns/apsw/issues/207">APSW issue 207</a>)</p>

<h2>3.11.0-r1<a class="headerlink" href="#id3" title="Permalink to this headline">¶</a></h2>
<p>The shell dump command now outputs the page size and user version. They were
both output before as comments.</p>
<p>Updated SQLite download logic for 2016 folder.</p>
<p>Updated VFS test suite due to changes in SQLite default VFS implemented methods.</p>
<p>Added SQLITE_INDEX_CONSTRAINT_LIKE, SQLITE_INDEX_CONSTRAINT_REGEXP,
SQLITE_INDEX_CONSTRAINT_GLOB, SQLITE_IOERR_AUTH, SQLITE_FCNTL_JOURNAL_POINTER,
and SQLITE_FCNTL_VFS_POINTER constants.</p>

releases for these extensions to mature.</p>
<p>Added a mapping for <a class="reference external" href="https://sqlite.org/c3ref/c_index_scan_unique.html">virtual table scan flags</a></p>
<p>Use <a class="reference external" href="https://www.sqlite.org/compile.html#enable_api_armor">SQLITE_ENABLE_API_ARMOR</a> for extra error
checking.</p>

<p>setup’s fetch command can now get arbitrary fossil versions. For
example specify <code class="docutils literal"><span class="pre">fossil-e596a6b6</span></code>.</p>
<p>Update tests due to a change in Python 3.5 (exception returned with
invalid strings for system calls changed from TypeError to
ValueError).</p>

<p>With the shell, you can specify handling of characters not present in

<div class="section" id="id51">
<h2>3.7.0-r1<a class="headerlink" href="#id51" title="Permalink to this headline">¶</a></h2>
<p>Added several new constants.</p>
<p><a class="reference external" href="https://sqlite.org/wal.html">Write Ahead Logging</a> is
<a class="reference internal" href="tips.html#wal"><span>supported</span></a>. You can make all databases automatically use
WAL mode if available by using <a class="reference internal" href="tips.html#wal"><span>connection hooks</span></a>.</p>
<p>Added <a class="reference internal" href="apsw.html#apsw.format_sql_value" title="apsw.format_sql_value"><code class="xref py py-meth docutils literal"><span class="pre">format_sql_value()</span></code></a> for generating a SQL syntax string from
a value. This is implemented in C and is significantly faster than
doing the same formatting in Python.</p>
<p>Using the above function and other tweaks the <a class="reference internal" href="shell.html#shell"><span>Shell</span></a> dumper is
now three to four times faster. Thanks to Nikolaus Rath for pointing
out the problem and providing test data.</p>
<p>The shell now does colour highlighting making it easy to visually
distinguish prompts, errors, headers and value types when outputting
to a terminal. See the <code class="xref std std-option docutils literal"><span class="pre">--no-colour</span></code> argument and <strong>.colour</strong>
command. Those of you in the two countries that have not adopted the
metric system may also omit the ‘u’. For Windows users you won’t get
colour output unless you install <a class="reference external" href="http://pypi.python.org/pypi/colorama">colorama</a></p>
<p>When using the context manager (with statement) of a
<a class="reference internal" href="connection.html#apsw.Connection" title="apsw.Connection"><code class="xref py py-class docutils literal"><span class="pre">Connection</span></code></a> and the exit commit had an error, then the
transaction is rolled back. This could occur if SQLite had buffered
the transaction entirely in memory and a non-eager transaction lock
had been obtained. Thanks to Geoff Ness for finding the problem.
(<a class="reference external" href="https://github.com/rogerbinns/apsw/issues/98">APSW issue 98</a>).</p>
<p>Fixed bug when an error is returned creating an instance of a virtual
table (eg an invalid column name). Before the fix you would get the
previous error message or a crash. Thanks to Jose Gomes for finding
the problem. <a class="reference external" href="https://github.com/rogerbinns/apsw/issues/103">APSW issue 103</a></p>
<p>There is now a PPA for Ubuntu users that is kept up to date with APSW
and SQLite at <a class="reference external" href="https://launchpad.net/~ubuntu-rogerbinns/+archive/apsw">https://launchpad.net/~ubuntu-rogerbinns/+archive/apsw</a>
which has the latest SQLite embedded statically inside (ie system
SQLite is ignored) and has all the extensions enabled: FTS3, RTree,
ICU, asyncvfs</p>
<p>If you open VFS files directly then the filename is always run through
xFullPathname first. SQLite guarantees this behaviour but the
existing VFS code was not doing that for direct opens. Opens from
SQLite were doing it.</p>
<p>Fixed error where <a class="reference internal" href="apsw.html#apsw.connection_hooks" title="apsw.connection_hooks"><code class="xref py py-attr docutils literal"><span class="pre">apsw.connection_hooks</span></code></a> were being run before

<p><strong>Backwards incompatible change</strong> The <a class="reference internal" href="apsw.html#apsw.complete" title="apsw.complete"><code class="xref py py-meth docutils literal"><span class="pre">complete()</span></code></a> method
has moved from <a class="reference internal" href="connection.html#apsw.Connection" title="apsw.Connection"><code class="xref py py-class docutils literal"><span class="pre">Connection</span></code></a> to <a class="reference internal" href="apsw.html#module-apsw" title="apsw: Python access to SQLite database library"><code class="xref py py-mod docutils literal"><span class="pre">apsw</span></code></a> where it should have

commands and output modes, or just run it like this:</p>
<div class="highlight-python"><div class="highlight"><pre>$ python -c "import apsw ; apsw.main()"

is possible on Unix like operating systems, especially if you use the
<a class="reference external" href="http://docs.python.org/library/multiprocessing.html">multiprocessing module</a>.</p>
<p>Extension loading is now compiled in by default when using the
amalgamation and compiled out when using existing libraries. This is
more likely to match your machine. You can use
<code class="xref std std-option docutils literal"><span class="pre">--omit=load_extension</span></code> or <code class="xref std std-option docutils literal"><span class="pre">--enable=load_extension</span></code>
to the build/build_ext commands to explicitly disable/enable extension

<p>Revert to using older SQLite APIs in order to work around
<a class="reference external" href="https://sqlite.org/cvstrac/tktview?tn=2158">SQLite ticket #2158</a>. (This also saves a little bit of SQLite memory
usage). The user visible effect was that you could get different
exceptions and error text depending on whether a query was already in
the <a class="reference internal" href="execution.html#statementcache"><span>statement cache</span></a> or if you were
multi-threading. As an example, if you have a query that used an
unknown collation then SQLite’s <a class="reference external" href="https://sqlite.org/c3ref/prepare.html">prepare</a> returns
<code class="xref py py-const docutils literal"><span class="pre">SQLITE_ERROR</span></code> with error text about the bad collation. If a

<p>The distribution now includes a <a class="reference internal" href="benchmarking.html#speedtest"><span>speedtest</span></a> script. You can use
this to see how APSW performs relative to pysqlite, or to track

<p>The statement cache was completely rewritten. It uses less memory and

<p>It was possible to get a deadlock between the Python GIL and the
SQLite database mutex when using the same <a class="reference internal" href="connection.html#apsw.Connection" title="apsw.Connection"><code class="xref py py-class docutils literal"><span class="pre">Connection</span></code></a> across

amicitas reporting this as <a class="reference external" href="https://github.com/rogerbinns/apsw/issues/31">APSW issue 31</a></p>
<p>SQLite’s API has been extended in 3.6.5 so that errors can be
retrieved in a thread safe manner. APSW now uses this API.</p>

<p>Documentation is now done using <a class="reference external" href="http://sphinx.pocoo.org">Sphinx</a>
which was adopted by Python 2.6 and 3. This has allowed for richer
documentation and more output formats such as PDF and <a class="reference external" href="http://en.wikipedia.org/wiki/Microsoft_Compiled_HTML_Help">Windows CHM</a> format.</p>
<p>The binary distribution for Windows includes the <a class="reference external" href="https://sqlite.org/fts3.html">full text search</a> (FTS) and <a class="reference external" href="https://sqlite.org/src/finfo?name=ext/rtree/README">Rtree</a> extensions.

<p>You can use this with SQLite 3.5.9 onwards.</p>
<p>SQLite now provides the source all <a class="reference external" href="https://sqlite.org/cvstrac/wiki?p=TheAmalgamation">amalgamated</a> into one file

<p>SQLite has implementation limits on string and blob lengths (roughly
constrained to fitting within a signed 32 bit integer - less than 2GB)
which weren’t checked. Using a 64 bit Python 2.5+ (as I do) it would
have been possible to destroy memory and crash the
program. Consequently APSW has length checks to ensure it doesn’t
happen. SQLite now has further <a class="reference external" href="https://sqlite.org/limits.html">limits checking</a> which cover other things as well
such as maximum number of virtual machine opcodes, maximum number of
variables etc. These are very useful if you are taking in SQL
statements from elsewhere. Call <a class="reference internal" href="connection.html#apsw.Connection.limit" title="apsw.Connection.limit"><code class="xref py py-func docutils literal"><span class="pre">Connection.limit()</span></code></a></p>
<p>A rename method was added for virtual tables.</p>
<p>SQLite 3.5 removed the requirement that all operations on a connection
be done in the same thread. Consequently all code that enforced the
restriction has been removed from APSW.</p>
<p>You no longer have to call <a class="reference internal" href="connection.html#apsw.Connection.close" title="apsw.Connection.close"><code class="xref py py-func docutils literal"><span class="pre">Connection.close()</span></code></a>. This was
previously a requirement to ensure that the correct thread was used
(destructors otherwise run in any thread). It is however still a good
idea to do so since you can catch exceptions when close is called
but not if you let the destructor do the closing.</p>
<p>SQLite now has incremental <a class="reference internal" href="blob.html#blobio"><span>blob I/O</span></a></p>
<p><a class="reference external" href="https://github.com/rogerbinns/apsw/issues/4">APSW issue 4</a> which could lead to generic error messages was fixed in

converted to utf8.</p>
<p>Use the <a class="reference external" href="https://sqlite.org/c3ref/open.html">sqlite3_open_v2</a>
interface which allows specifying which vfs to use. This release does
not allow you to write your own vfs as the SQLite vfs interface is
being changed for SQLite 3.6.</p>
<p>Used new SQLite functions that keep track of when virtual tables and
collations are no longer used so they can be released. Previously APSW
also had to keep track duplicating effort.</p>
<p>Improved test coverage a few more percent.</p>
<p>The statement cache now defaults to the same number of entries as

destructors. Unfortunately it is almost completely useless, merely
printing <code class="xref py py-func docutils literal"><span class="pre">str()</span></code> of the object and exception. This doesn’t help in
finding where in your code the issue arose so you could fix it. An
internal APSW implementation generates a traceback and calls

<p>SQLite added several functions for returning metadata about result
column sets. You have to compile SQLite with
<code class="xref py py-const docutils literal"><span class="pre">SQLITE_ENABLE_COLUMN_METADATA</span></code> to get them. This is not the
default for SQLite. I don’t believe these are generally useful except
in some corner cases and so they aren’t wrapped. However please shout

<strong class="command">python tests.py -v</strong> to get the tests run. There should be no
errors.</p>
<p>Updated code to work correctly with new <code class="xref c c-type docutils literal"><span class="pre">Py_ssize_t</span></code> introduced
in Python 2.5. See <a class="reference internal" href="execution.html#x64bitpy25"><span>64 bit hosts, Python 2.5+</span></a> for
more details on how Python and SQLite handle 64 bit sized items.</p>
<p>The following functions were added to SQLite and are wrapped. They are
all functions defined on the <a class="reference internal" href="connection.html#apsw.Connection" title="apsw.Connection"><code class="xref py py-class docutils literal"><span class="pre">Connection</span></code></a> object or <a class="reference internal" href="apsw.html#module-apsw" title="apsw: Python access to SQLite database library"><code class="xref py py-mod docutils literal"><span class="pre">apsw</span></code></a>

<h2>3.2.7-r1<a class="headerlink" href="#id79" title="Permalink to this headline">¶</a></h2>
<p>You can use this release against any release of SQLite 3.</p>
<p>SQLite 3.2.7 has several bug fixes. The undocumented experimental
function <code class="xref py py-func docutils literal"><span class="pre">sqlite3_profile()</span></code> was added, but it not present in apsw
yet.</p>
<p>The author of pysqlite has improved it considerably since APSW was
originally written. The differences section has been updated to
reflect those improvements in pysqlite.</p>
<p><code class="xref py py-const docutils literal"><span class="pre">SQLITE_INTERNAL</span></code> and <code class="xref py py-const docutils literal"><span class="pre">SQLITE_NOTFOUND</span></code> error codes are
not used according to 3.2.7 header file. They are still present in
APSW for backwards compatibility.</p>
<p>Changed the build instructions so configure is run on non-Windows
platforms.</p>
<p>Fixed a bug caused by an overly helpful error message trying to tell
you how many bindings you supplied that crashed if you didn’t supply
any.</p>
<p>Changed when an error in the step function for an aggregate is
reported due to limitations in SQLite.</p>
</div>
<div class="section" id="id80">
<h2>3.2.2-r1<a class="headerlink" href="#id80" title="Permalink to this headline">¶</a></h2>
<p>You can use this release against any release of SQLite 3.</p>
<p>SQLite 3.2.2 API removed <code class="xref py py-func docutils literal"><span class="pre">sqlite3_global_recover()</span></code>. That function
was not wrapped in APSW. Note that SQLite 3.2.2 contains a bug fix
that applies when you use 64 bit integer primary keys (32 bit ints are
fine).</p>
</div>
<div class="section" id="id81">
<h2>3.2.1-r1<a class="headerlink" href="#id81" title="Permalink to this headline">¶</a></h2>
<p>You can use this release against any release of SQLite 3.</p>
<p>There are no changes in APSW except to correct an error in the example
code (collations are registered against the connection not the cursor)</p>
<p>SQLite 3.2.1 had one addition in the stable C API, which was a new
function named <code class="xref py py-func docutils literal"><span class="pre">sqlite3_global_recover()</span></code>. That function is not
applicable for wrapping in APSW.</p>
</div>
<div class="section" id="id82">
<h2>3.1.3-r1<a class="headerlink" href="#id82" title="Permalink to this headline">¶</a></h2>
<p>You can use this release against any release of SQLite 3.</p>
<p>The text string returned by apsw.Error used to say
“apsw.APSWException” and has been changed to “apsw.Error”. This is
purely cosmetic and helps make clear what the class is. (The old
string was what the original class name was in an earlier version of
the code.)</p>
<p>Added <code class="xref py py-const docutils literal"><span class="pre">SQLITE_ALTER_TABLE</span></code> and <code class="xref py py-const docutils literal"><span class="pre">SQLITE_REINDEX</span></code>
constants for the authorizer function. (These constants were
introduced in SQLite 3.1.3).</p>
<p>Changed various C++-isms into standard C (eg // comments and the
placing of some <code class="xref c c-macro docutils literal"><span class="pre">CHECK_THREAD</span></code> macro calls).</p>
<p>Added module level function <a class="reference internal" href="apsw.html#apsw.apswversion" title="apsw.apswversion"><code class="xref py py-meth docutils literal"><span class="pre">apswversion()</span></code></a> which returns
the version of APSW.</p>
<p>SQLite 3.1.3 had no changes in the stable C API other than what is
mentioned above. There were some new experimental functions added
which are not currently documented on the SQLite website, which are
not wrapped by APSW. Please contact me if you believe they will
remain in SQLite and you would like them wrapped:</p>
<ul class="simple">
<li><code class="xref c c-func docutils literal"><span class="pre">sqlite3_sleep()</span></code> An alternative function which sleeps for a
specified number of milliseconds can be provided. By default SQLite
just uses the standard operating system call.</li>
<li><code class="xref c c-func docutils literal"><span class="pre">sqlite3_expired()</span></code> This function is internal to statement
execution. It would apply to the implementation of
<a class="reference internal" href="cursor.html#apsw.Cursor.executemany" title="apsw.Cursor.executemany"><code class="xref py py-meth docutils literal"><span class="pre">Cursor.executemany()</span></code></a> and could in theory provide a marginal
improvement in performance.</li>
<li>A global variable <code class="xref c c-data docutils literal"><span class="pre">sqlite3_temp_directory</span></code> can be used before
any databases are opened to set where temporary files are created. By
default SQLite just uses the standard operating system mechanisms.</li>
</ul>
</div>
<div class="section" id="r3">
<h2>3.0.8-r3<a class="headerlink" href="#r3" title="Permalink to this headline">¶</a></h2>
<p>There are no functional changes. The only changes were to correct some
variable names in the example code (they were cut and pasted from the
test code which used different names) and to make the source zip file
extract its contents into a sub-directory which is the more typical
way of packaging that sort of thing.</p>
</div>
<div class="section" id="id83">
<h2>3.0.8-r2<a class="headerlink" href="#id83" title="Permalink to this headline">¶</a></h2>

available.</p>
