            <title>[SERVER-34630] Change WiredTiger compatibility version setting in 3.6 release</title>
                <link>https://jira.mongodb.org/browse/SERVER-34630</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;We are introducing a log format version change in the 4.0 release, as part of recoverable rollback work. The change is being made in &lt;a href=&quot;https://jira.mongodb.org/browse/WT-4029&quot; title=&quot;Bump the log file version&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-4029&quot;&gt;&lt;del&gt;WT-4029&lt;/del&gt;&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;We should update MongoDB to pass &lt;tt&gt;compatibility=(release=3.0)&lt;/tt&gt; when it calls &lt;tt&gt;wiredtiger_open&lt;/tt&gt;, so that users who open a database that has been used by MongoDB 4.0 and has not had a clean shutdown get a useful error message.&lt;/p&gt;</description>

I&apos;ve opened &lt;a href=&quot;https://jira.mongodb.org/browse/WT-4098&quot; title=&quot;Add new compatibility_max configuration option&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-4098&quot;&gt;&lt;del&gt;WT-4098&lt;/del&gt;&lt;/a&gt; to track adding a &lt;tt&gt;requires_max&lt;/tt&gt; option. I think we should hold off on pushing a change here until that functionality is added, and co-ordinate updating the version of WiredTiger in 3.6 to include that ticket, and pushing a SERVER change to enable using it.&lt;/p&gt;</comment>
                            <comment id="1894354" author="michael.cahill" created="Thu, 17 May 2018 18:33:28 +0000"  >&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=alexander.gorrod&quot; class=&quot;user-hover&quot; rel=&quot;alexander.gorrod&quot;&gt;alexander.gorrod&lt;/a&gt;, is the change proposed here (together with &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-32590&quot; title=&quot;RTT 3.6&amp;lt;-&amp;gt;4.0 upgrade/downgrade.&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-32590&quot;&gt;&lt;del&gt;SERVER-32590&lt;/del&gt;&lt;/a&gt;) sufficient to close this ticket?&lt;/p&gt;

&lt;p&gt;Is there an additional constraint that to keep WT&apos;s &lt;tt&gt;mongodb-3.6&lt;/tt&gt; branch in sync with &lt;tt&gt;develop&lt;/tt&gt;, we&apos;ll need a way to force startup to fail if the files on disk are too new?  In other words, do we need &lt;tt&gt;require_max&lt;/tt&gt; as well as &lt;tt&gt;require_min&lt;/tt&gt;?&lt;/p&gt;</comment>

&lt;p&gt;Daniel Gottlieb Could you confirm that the above is what you expect, and setup changes so that the correct WiredTiger versions are configured for the different MongoDB versions and configurations?&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;I might be missing the intent behind the &quot;Upgraded/Downgraded&quot; column, but omitting that results in the same &lt;tt&gt;WiredTiger log version&lt;/tt&gt;, so I presume it&apos;s a benign addition. Regardless, the resulting WT log versions are correct.&lt;/p&gt;</comment>
                            <comment id="1887657" author="alexander.gorrod" created="Wed, 9 May 2018 22:53:07 +0000"  >&lt;p&gt;The WiredTiger side of this work is done and staged - our testing indicates that this needs more careful co-ordination than expected to avoid introducing automated test regressions.&lt;/p&gt;

&lt;p&gt;When running the &lt;tt&gt;do_upgrade_downgrade.js&lt;/tt&gt; multiversion test, it fails if we include the WiredTiger log file version change with:&lt;/p&gt;

It doesn&apos;t need to happen after &lt;a href=&quot;https://jira.mongodb.org/browse/WT-4029&quot; title=&quot;Bump the log file version&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-4029&quot;&gt;&lt;del&gt;WT-4029&lt;/del&gt;&lt;/a&gt; lands - the change should be made directly in the v3.6 branch of MongoDB - we don&apos;t want it to be made in master. &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=sueloverso&quot; class=&quot;user-hover&quot; rel=&quot;sueloverso&quot;&gt;sueloverso&lt;/a&gt; is working on &lt;a href=&quot;https://jira.mongodb.org/browse/WT-4029&quot; title=&quot;Bump the log file version&quot; class=&quot;issue-link&quot; data-issue-key=&quot;WT-4029&quot;&gt;&lt;del&gt;WT-4029&lt;/del&gt;&lt;/a&gt; so should be able to talk through the details if you have questions.&lt;/p&gt;

&lt;p&gt;&lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=milkie&quot; class=&quot;user-hover&quot; rel=&quot;milkie&quot;&gt;milkie&lt;/a&gt; The fix version on this ticket is a bit strange - this change is targeted at the 3.6 release, but should be made prior to 4.0 being cut. Feel free to adjust the ticket setup to reflect that intended state of affairs.&lt;/p&gt;</comment>
