| Doc Text: |
Previously, qpid-config did not provide any access to the "arguments" field of an exchange-bind operation for header and xml exchanges because no binding key was set before the "any" or "all" keyword. With this update, users can specify needed parameters for queue to header and/or xml exchange binding.

Let me know if I'm missing there something. The source of commands above is from qpid-config --help & permutations/variations. -> ASSIGNED The issue here is in the help-string/usage for qpid-config which says the following with regard to the "bind" operation:
qpid-config [OPTIONS] bind <exchange-name> <queue-name> [binding-key]
<for type xml> [-f -|filename]
<for type header> [all|any] k1=v1 [, k2=v2...]
For XML and Headers exchanges, the binding-key is not optional and must be supplied before the "any" or "all" keyword. In the above report, "all" is being interpreted as the binding key.
The reason the binding key is required is that without it, the binding cannot be deleted. For XML and Headers exchanges, the binding key serves only as a handle by which a binding can be referred to.
I can confirm the above comment 4, testing with given <binding-key> works well. I believe qpid-config usage text should be modified or alternatively rel. note should describe this case.

An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on therefore solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHSA-2010-0773.html |
qpid-config does not provide any access to the "arguments" field of an exchange-bind operation. For the Headers exchange, the user must be able to specify an operator ('any' or 'all) and a set of key/value pairs. For the XML exchange, the user must be able to supply an XQuery document. This could be done via stdin or from an input file. It would probably be good to use a well-established convention (i.e. "-" for stdin or "-f <filename>" for an input file)
