            <title>[CDRIVER-2764] aggregate inherits writeConcern only if the &quot;pipeline&quot; parameter contains a &quot;pipeline&quot; field</title>
                <link>https://jira.mongodb.org/browse/CDRIVER-2764</link>
                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;mongo_collection_aggregate used to accept only a document that includes a &quot;pipeline&quot; array. A pipeline that includes an $out stage looks like:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;{pipeline: [{...}, {$out: ...}]}&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;If the function finds &quot;$out&quot; but there&apos;s no explicit writeConcern then it inherits the collection&apos;s writeConcern, per spec.&lt;/p&gt;

&lt;p&gt;In &lt;a href=&quot;https://jira.mongodb.org/browse/CDRIVER-2606&quot; title=&quot;mongoc_collection_watch pipeline argument should allow bson array&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CDRIVER-2606&quot;&gt;&lt;del&gt;CDRIVER-2606&lt;/del&gt;&lt;/a&gt; we also accept a BSON array passed directly, not as an element of the input document. That work was incomplete: if mongoc_collection_aggregate is passed a BSON array directly then it doesn&apos;t search the array for &quot;$out&quot; and doesn&apos;t inherit writeConcern from its collection object.&lt;/p&gt;</description>
