            <title>[SERVER-6162] backport of targeted shard ranges instead of broadcast on all queries</title>
                <link>https://jira.mongodb.org/browse/SERVER-6162</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We shouldn&apos;t ever send queries to shards where the collection does not exist - this can introduce version issues (since version 0 is &quot;special&quot;) and cause problems when dropping shards (since the dropped shards are also targeted until refreshed).  &lt;/p&gt;

&lt;p&gt;Proposing backport of f93918db (partial or full) - we previously didn&apos;t backport b/c potentially a bit dangerous, but has not caused any problems in master for several months, so it&apos;s probably burned-in enough.&lt;/p&gt;</description>

&lt;p&gt;The test jstests/sharding/no_empty_reset.js was using some&lt;br/&gt;
functionality that wasn&apos;t present in the 2.0 shell.  Add code&lt;br/&gt;
to find the shard name manually to adapt for this.&lt;br/&gt;
Branch: v2.0&lt;br/&gt;

&lt;p&gt;test and fix for zero-version being sent to unneeded shards during scatter/gather&lt;/p&gt;

&lt;p&gt;Backport based on f93918db8ec15c9de7c884d0a560a185a8ef423d&lt;/p&gt;
