Scope

In master branch

• source/includes/currentOp-output-example.rst:7             "threadId" : <string>
• source/reference/command/currentOp.txt:209 .. data:: currentOp.threadId
• source/reference/method/cursor.comment.txt:131             "threadId" : "0x10772e000"
• 4.0-compatibility mentions the removal, instead of the specific currentOp (pipeline/command/shell helper pages as it doesn't seem that helpful on those pages)

• Backport to 3.6 

ToDo work at TBD

We need to audit the currentOp page for 3.6 changes as not sure when last audited and updated wholesale.

Documentation Request Summary:

The currentOp output no longer includes the "threadId" of the thread running the op. This was removed because it can leak sensitive info on some platforms.

Engineering Ticket Description:

Client::_desc is initialized as the string "conn" rather than the string "conn" + session->id().

• https://github.com/mongodb/mongo/blob/r3.6.0/src/mongo/db/client.cpp#L112

Note: It is still possible to reconstruct the thread name via the "connectionId" field in the currentOp output.
