================ Written by Hallvard B. Furuseth and placed into the public domain. This software is not subject to any license of the University of Oslo. ================ Here is a patch which does what I described. Of course, someone has to decide if that is the right solution:-) - Add an "opid:" line to the input to back-shell commands. - Add an "abandonid: <opid> line to back-shell/abandon input. - Replace message id with opid in back-tcl arguments. - Add an abandonid = <opid> argument to back-tcl/abandon. An opid (operation ID) is a "connection ID/message ID" string. I would have liked to use another name to avoid confusion with struct slap_op->o_opid, but I could not think of another apt word. This also fixes ITS#1784 and ITS#1792. Since calling conventions changed anyway, I fixed back-shell by adding abandonid: and making opid: always be the ID of the current operation. Hallvard B.
