Update checker build to checker-257. llvm-svn: 132060
2011-05-26 00:30:14 +08:00
<h4 id="checker_257">checker-257</h4>
<p><b>built:</b>May 25, 2011<br>
<b>download:</b> <a href="/checker/checker-257.tar.bz2">checker-257.tar.bz2</a></p>
<p><b>highlights:</b></p>
<ul>
<li>The analyzer is now far more aggressive with checking conformance with Core Foundation conventions. Any function that returns a CF type must now obey the Core Foundation naming conventions, or use the <a href="/annotations.html#attr_cf_returns_retained">cf_returns_retained</a> or <a href="/annotations.html#attr_cf_returns_not_retained">cf_returns_not_retained</a> annotations.</li>
<li>Fixed a serious regression where the analyzer would not analyze Objective-C methods in class extensions.</li>
<li>Misc. bug fixes to improve analyzer precision.
</li>
</ul>

Update public analyzer build to checker-256. llvm-svn: 129473
2011-04-14 05:48:34 +08:00
<b>download:</b> <a href="/checker/checker-256.tar.bz2">checker-256.tar.bz2</a></p>
<p><b>highlights:</b></p>
<ul>
<li>Lots of bug fixes and improvements to analyzer precision (fewer false positives, possibly more bugs found).
<li>Introductory analysis support for C++ and Objective-C++.
</ul>
<p>This build contains basic support for C++ and Objective-C++ that is ready to be tried out
by general users. It is still in its infancy, but establishes a baseline for things to come. The main hope is that it can find some
issues and have a reasonable false positive rate.</p>
<p><b>Please</b> <a href="/filing_bugs.html">file bugs</a> when you see issues of any kind so we can assess
where development on C++ analysis support needs to be focused.</p>
<p>To try out C++ analysis support, it should work out of the box using <tt>scan-build</tt>. If you are using this checker build
as a replacement to the analyzer bundled with Xcode, first use the <tt>set-xcode-analyzer</tt> script to <a href="/xcode.html">change Xcode to use
your version of the analyzer</a>. You will then need to modify one configuration file in Xcode to enable C++ analysis support. This can
be done with the following steps:</p>
<ol>
<li>Find the clang .xcspec file:
<pre>$ cd /Developer/Library
$ find . | grep xcspec | grep Clang
./Xcode/<b>&lt;SNIP&gt;</b>/Clang LLVM 1.0.xcplugin/Contents/Resources/Clang LLVM 1.0.xcspec
</pre></li>
<li>The exact location of the file may vary depending on your installation of Xcode. Edit that file, and look for the string &quot;--analyze&quot;:
<pre>
SourceFileOption = "--analyze";
FileTypes = (
"sourcecode.c.c",
"sourcecode.c.objc",
);
...
</pre>
Change the &quot;FileTypes&quot; entry to:
<pre>
FileTypes = (
"sourcecode.c.c",
"sourcecode.c.objc",
"sourcecode.cpp.cpp",
"sourcecode.cpp.objcpp",
);
</pre></li>
<li>Restart Xcode.</li>
</ol>
Update static analyzer build to checker-255. llvm-svn: 125432

<p><b>highlights:</b></p>
<ul>
<li>Introduces new <tt>-init</tt> method checker to check if a super class's init method is properly called.</li>
<li>Objective-C retain/release checker now reasons about calls to property accessor methods (setter/getter).</li>
<li>Introduces new attribute <a href="annotations.html#attr_ns_consumes_self">ns_consumes_self</a> to educate the Objective-C retain/release checker about custom &quot;init-like&quot; methods that do not follow the standard Cocoa naming conventions.</li>
<li>Introduces new attributes <a href="annotations.html#attr_ns_consumed">ns_consumed</a> and <a href="annotations.html#attr_cf_consumed">cf_consumed</a> to educate the Objective-C retain/release checker about methods/functions that decrement the reference count of a parameter.</li>
