            <title>[SERVER-76879] Config Fuzzer Enhancements</title>
                <link>https://jira.mongodb.org/browse/SERVER-76879</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;After triaging, reviewing, debugging, and interacting with several config fuzzer Hot BFs this week, here is a list of proposals from a few members of StoreEx on how to improve the config fuzzer so that a server engineer can find root causes of test failures quicker:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;WT string split to multiple lines
	&lt;ul&gt;
		&lt;li&gt;Currently the WT config string is on one line which make diffing error-prone and time-consuming&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;show defaults, min/max for each setting inline
	&lt;ul&gt;
		&lt;li&gt;Configs can be surprising on first glance (a negative number?? must be a problem!)&lt;/li&gt;
		&lt;li&gt;Showing some of this background can illuminate how extreme or unusual the fuzzed parameter is&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
	&lt;li&gt;have fuzz seed be consistent across branches
	&lt;ul&gt;
		&lt;li&gt;currently, a fuzz seed does not generate the same configs on all commits nor branches. This makes comparisons hard to carry out.&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;
