            <title>[SERVER-8899] upgrading ShardChunkManager without write lock on setShardVersion can cause errors on writes</title>
                <link>https://jira.mongodb.org/browse/SERVER-8899</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When performing a write on a mongod with sharding enabled, we check the shard version of the message (handlePossibleShardedMessage()) before getting a write context (Client::Context) (see instance.cpp).  Getting a write context also performs a version check.  If the version changes between these checks, an error is thrown instead of the write being queued for writeback, and so the write fails.&lt;/p&gt;

&lt;p&gt;see &lt;a href=&quot;http://buildlogs.mongodb.org/OS%20X%2010.5%2064-bit%20DEBUG/builds/1862/test/sharding/mrShardedOutput.js?mode=raw&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;http://buildlogs.mongodb.org/OS%20X%2010.5%2064-bit%20DEBUG/builds/1862/test/sharding/mrShardedOutput.js?mode=raw&lt;/a&gt; &lt;/p&gt;

&lt;p&gt;The last two lines show the result of a setShardVersion and insert hitting m30000 at the same time (shard0000).&lt;/p&gt;

&lt;p&gt;Possible solution - read lock during ShardingState::trySetVersion()?&lt;/p&gt;</description>
