             Summary: [linearstore] Add qpid-txtest mode to qpid-qls-analyze which extracts message number from message body
                 Key: QPID-6757
                 URL: https://issues.apache.org/jira/browse/QPID-6757
             Project: Qpid
          Issue Type: Improvement
          Components: Python Tools
            Reporter: Kim van der Riet
            Assignee: Kim van der Riet
            Priority: Minor


When analysing linearstore journals using qpid-qls-analyze, it would be useful to be able to see the message number which this test inserts into the message body. When qpid-txtest fails, it reports these message numbers when they are either missing or duplicated.

To be able to usefully analyze a journal from this test, it is necessary to be able to view this message number. However, qpid-qls-analyze does not have any mechanism to display the message content except as part of a binary dump of which only the first and last 10 bytes are displayed with an ellipsis:

{{data(164)='\00\00\00p\0b\01\00\15\00\01 ... MNOPQRSTUV'}}

By adding a command-line flag {{\-\-txtest}}, qpid-qls-analyze would search the data for the string "msg-" and display the message number:

{{data(164)='msg-1086'}}

which is embedded in the binary and would normally be difficult to recover.
