            <title>[SERVER-59451] Evergreen-aware bisect</title>
                <link>https://jira.mongodb.org/browse/SERVER-59451</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Write a binary search function on Evergreen version history that simulates what git bisect does, but treat Evergreen versions as git commits if the build in a version for a particular variant has valid artifacts and binaries.&lt;/p&gt;

&lt;p&gt;0. Ask the user for the branch to bisect as a cmdline arg and find the corresponding Evergreen projects for that branch (It should just all be &quot;mongodb-mongo-&quot; + branch name)&lt;br/&gt;
1. Count all commits in the branch and store them in memory up to lookbackDays,&lt;br/&gt;
2. update multiversion_setup to allow users to specific a variant on the command line which supersedes the --platform, --edition, and --architecture options. Code is &lt;a href=&quot;https://github.com/mongodb/mongo/blob/70e319a707543052f46ef77f370e91252f50e968/buildscripts/resmokelib/setup_multiversion/setup_multiversion.py#L384&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;. The variant name gets used &lt;a href=&quot;https://github.com/mongodb/mongo/blob/70e319a707543052f46ef77f370e91252f50e968/buildscripts/resmokelib/setup_multiversion/setup_multiversion.py#L251&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;&lt;br/&gt;
3. Find the middle Evergreen version&lt;br/&gt;
4. Set up the dev environment using setup-multiversion, optionally &lt;tt&gt;pip install buildscripts/dev-requirements.txt&lt;/tt&gt; if there isn&apos;t an existing python virtualenv from Evergreen (which there isn&apos;t for commits older than a few months).&lt;br/&gt;
5. function to run a script that checks if the commit is good or bad (&quot;git bisect run my_script arguments&quot;)&lt;br/&gt;
6. based on result of function in step 4, bisect to the right or left accordingly.&lt;br/&gt;
7. Tell the user that the problem is within a certain commit range, where the range is contains two consecutive Evergreen runs, with the earlier one passing and later one failing.&lt;/p&gt;</description>

Also, we do not ned to download the debug symbols since those are only relevant for failures that result in a hang and need to be used for the hang analyzer.&lt;/p&gt;</comment>
