            <title>[SERVER-86362] Move platform based code in separate .cpp files for AtomicWaitable and use respective OS primitives.</title>
                <link>https://jira.mongodb.org/browse/SERVER-86362</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-81797&quot; title=&quot;Make our own portable implementation of atomic notify() and wait() with timeout support&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-81797&quot;&gt;SERVER-81797&lt;/a&gt; introduces AtomicWaitable type and uses futex sys operations for linux and mutex+condition_var solution for non linux.&#160;&lt;/p&gt;
&lt;ol&gt;
	&lt;li&gt;Add separate .cpp files for windows, linux and macOS&lt;img class=&quot;emoticon&quot; src=&quot;https://jira.mongodb.org/images/icons/emoticons/help_16.png&quot; height=&quot;16&quot; width=&quot;16&quot; align=&quot;absmiddle&quot; alt=&quot;&quot; border=&quot;0&quot;/&gt;&lt;/li&gt;
	&lt;li&gt;Use OS based wake/wait functions.&#160;&lt;/li&gt;
&lt;/ol&gt;


&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;For windows - it can use &lt;a href=&quot;https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitonaddress&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;WaitOnAddress&lt;/a&gt; / &lt;a href=&quot;https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-wakebyaddresssingle&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;WakeByAddressSingle&lt;/a&gt; / &lt;a href=&quot;https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-wakebyaddressall&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;WakeByAddressAll&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;On MacOS - we can use[ _&lt;em&gt;ulock_wait/&lt;/em&gt;_ulock_wake|https://outerproduct.net/futex-dictionary.html#macos].&lt;/p&gt;</description>
