            <title>[CDRIVER-2529] Consider using memory checking tools on Darwin and Windows</title>
                <link>https://jira.mongodb.org/browse/CDRIVER-2529</link>
                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;Platforms other than Linux don&apos;t benefit from our Valgrind evergreen tasks. We can consider making tasks to use tools like&lt;br/&gt;
&lt;tt&gt;leaks&lt;/tt&gt; on macOS, which can run a process and print a list of leaks detected at exit:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;leaks -atExit ./test-libmongoc --no-fork&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Another tool on macOS that looks interesting is &lt;tt&gt;libgmalloc&lt;/tt&gt;, which overrides the behavior of malloc and detects memory errors like use-after-free. &lt;tt&gt;man libgmalloc&lt;/tt&gt; shows how to use this with:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;DYLD_INSERT_LIBRARIES=/usr/lib/libgmalloc.dylib ./test-libmongoc --no-fork&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;We also can research memory checking command line tools for Windows.&lt;/p&gt;</description>

                            <comment id="1842814" author="jesse" created="Fri, 23 Mar 2018 01:24:32 +0000"  >&lt;p&gt;JetBrains has valgrind working in WSL (Windows subsystem for Linux) if you use CLion, it suggests we should be able to use WSL and valgrind in an Evergreen script:&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://blog.jetbrains.com/clion/2018/02/clion-2018-1-eap-valgrind-wsl-partial-commits-cpp-support/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://blog.jetbrains.com/clion/2018/02/clion-2018-1-eap-valgrind-wsl-partial-commits-cpp-support/&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;But we need to research whether the WSL environment represents how Windows users will really run the driver. E.g., if the driver ends up using OpenSSL instead of SChannel in this environment then we haven&apos;t gained any test coverage.&lt;/p&gt;</comment>
