Hi,
I was thinking we could change the virtualhosts.xml so that structures like:
<queue>
<name>test-queue</name>
<test-queue>
<exchange>test.direct</exchange>
<durable>true</durable>
</test-queue>
</queue>
which make the validation of the xml file cumbersome would be replaced with
something like:
<queue name="test-queue">
<exchange>test.direct</exchange>
<durable>true</durable>
</queue>
which could be simple to validate and would make the configuration much
easier to read. With this, we can validate
the whole configuration (config.xml + virtualhosts.xml) given that in
config.xml we do not allow the definition of virtualhosts anymore but only a
pointer to virtualhosts.xml file. The same situation applies to virtualhost
and queue tags.
Also, we would be in a position to provide a command line option that would
only validate the configuration without starting the broker.
I am attaching an example of virtualhosts.xml along with a DTD (XSD coming
shortly).
Raised QPID-2544 to track the progress.
Thoughts? Comments?
TIA,
