            <title>[SERVER-27831] Deadlock when listing collections on &quot;local&quot; database with replication enabled for KVCatalog-based storage engines without document locking</title>
                <link>https://jira.mongodb.org/browse/SERVER-27831</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Storage engines which use the &lt;tt&gt;KVCatalog&lt;/tt&gt;, but do not support document-level concurrency (such as the ephemeralForTest storage engine) may experience deadlock because of the incompatible acquisition order of the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.5.2/src/mongo/db/storage/kv/kv_catalog.cpp#L58&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;resourceIdCatalogMetadata&lt;/tt&gt;&lt;/a&gt; and the &quot;local&quot; database locks. This bug does not apply to the MMAPv1 or WiredTiger storage engines.&lt;/p&gt;

&lt;p/&gt;

&lt;p&gt;The &lt;tt&gt;resourceIdCatalogMetadata&lt;/tt&gt; lock is acquired &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.5.2/src/mongo/db/storage/kv/kv_database_catalog_entry_base.cpp#L210&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;when calling &lt;tt&gt;KVCatalog::newCollection()&lt;/tt&gt; as part of &lt;tt&gt;Database::createCollection()&lt;/tt&gt;&lt;/a&gt;; however, the lock doesn&apos;t get released immediately after returning from there since it was acquired in &lt;tt&gt;MODE_X&lt;/tt&gt; inside a &lt;tt&gt;WriteUnitOfWork&lt;/tt&gt; causing &lt;a href=&quot;https://github.com/mongodb/mongo/blob/r3.5.2/src/mongo/db/concurrency/lock_state.cpp#L462-L465&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;shouldDelayUnlock()&lt;/tt&gt;&lt;/a&gt; to return true. This leads to the client creating a collection to be holding the &lt;tt&gt;resourceIdCatalogMetadata&lt;/tt&gt; lock while attempting to acquire a lock on the &quot;local&quot; database in order to write the corresponding oplog entry at the same time as the client listing collections on the &quot;local&quot; database to be holding a lock on the &quot;local&quot; database while attempting to acquire the &lt;tt&gt;resourceIdCatalogMetadata&lt;/tt&gt; lock to get the individual collection options.&lt;/p&gt;

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-27831&quot; title=&quot;Deadlock when listing collections on &amp;quot;local&amp;quot; database with replication enabled for KVCatalog-based storage engines without document locking&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-27831&quot;&gt;&lt;del&gt;SERVER-27831&lt;/del&gt;&lt;/a&gt; &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-28737&quot; title=&quot;Have ephemeralForTest use std::mutex for protecting its internal data structures&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-28737&quot;&gt;&lt;del&gt;SERVER-28737&lt;/del&gt;&lt;/a&gt;: Push threadsafety responsibility inside of KVCatalog&apos;s RecordStore&lt;/p&gt;

&lt;p&gt;RecordStores that don&apos;t implement document level locking are typically&lt;br/&gt;
protected from concurrent reads and writes. However one exception is the&lt;br/&gt;
RecordStore passed into KVCatalog. Previously, if&lt;br/&gt;
StorageEngine::supportsDocLocking was false, the KVCatalog would use&lt;br/&gt;
an additional lock that participated in two phase locking to ensure&lt;br/&gt;
reader-writer protection to the underlying record store (and more&lt;br/&gt;
specifically, delay releasing until any potential rollbacks were&lt;br/&gt;
processed). However, access to the catalog can happen anywhere and this&lt;br/&gt;
lock did not have a formally assigned acquisition time relative to other&lt;br/&gt;
locks resulting in potential deadlocks.&lt;/p&gt;

&lt;p&gt;This patch forces the thread-safety requirement into the RecordStore.&lt;br/&gt;
Specifically, EphemeralForTest was changed to acquire a finer grained&lt;br/&gt;
mutex (i.e: does not participate in two-phase locking) to protect its&lt;br/&gt;
internal state. Now that the lock exists inside EphemeralForTest, it is&lt;br/&gt;
also able to grab the mutex when needed for the onCommit/onRollback&lt;br/&gt;
callbacks.&lt;/p&gt;
