            <title>[CDRIVER-2106] Refactor code to not assume OP_REPLY is the only reply opcode</title>
                <link>https://jira.mongodb.org/browse/CDRIVER-2106</link>
                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;The cursors, and most of command infrastructure, has liberal assumption that the opcode they are working with is OP_REPLY.&lt;/p&gt;

&lt;p&gt;Aside from the OP_REPLY sanitychecks, it accesses the rpc structure in a intimate way rather then through a layer that abstracts the actual opcodes.&lt;/p&gt;

&lt;p&gt;There are also aggressive optimizations in the command infrastructure that instead of expecting a cursor it allocates the entire reply as a command reply, rather then reading the reply into buffer and present it as a bson, like the cursors do.&lt;/p&gt;

&lt;p&gt;These assumptions are no longer true for other opcdoes.&lt;/p&gt;</description>
