Filter consumed messages (-g) with the selector (-s) ?

[Frank Bartsch]

To cleanup a messy queue, I would like to consume (-g) all messages based on a specific selector.

Here is what I tried:

# Content of my queue:
########################

$ ./a  --broker tcp://test-broker-1:61616  test
-----------------
Message Properties
  event_category: trash
Payload:
{"logLevel":"INFO",
"messageId":"00004",
"serviceName":"auth",
"properties":{
        "inviteeName":"[e-mail]",
        "initiatorName":"admin"},
"created":"2017-04-12T13:48:36.368+02:00"}

-----------------
Message Properties
  event_category: can
Payload:
{"logLevel":"INFO",
"messageId":"00004",
"serviceName":"auth",

        "inviteeName":"[e-mail]",
        "initiatorName":"admin"},
"created":"2017-04-12T13:48:36.368+02:00"}

-----------------

"created":"2017-04-12T13:48:36.368+02:00"}

$ ./a  --broker tcp://test-broker-1:61616 -s "event_category='trash'" -c 0 -g  test

Since the documentation says:

-s,--selector Browse or get with selector

So now it could be a bug 🐛 or PEBKAC 😊 . In any case, I hope you can help me out here.

Thanks in advance!

Some times with remote brokers you need to provide some wait time. Default is 50ms, but with selectors over network it might not be enough. Try providing -w 1000. I tried to reproduce it, but it works as expected with a localhost broker. Maybe the 50ms default value should be longer.

Thanks for your suggestion. Unfortunately it doesn't work.
I tried -w 1000 with the same commands as above.

The used ActiveMQ Version is 5.14.1
