RE: [equinox-dev] Multiple users and the Equinox console

[Jeff McAffer <Jeff_McAffer@xxxxxxxxxx>]

Some comments
- We are actaully looking at breaking
the console out of the framework bundle.  it is interesting to have
in there but not for everyone.  There is no particular need for it
to be in the framework

- specing -console only controls whether
or not the console itself is started.  The bundles that register CommandProvider
services will still run (if they ran before) and as such, someone who looked
up the command providers will still be able to use the commands.  Note
that in general these command implementations are not that useful for other
purposes because they do things like output in a text format etc.  It
is more interesting to have access to the underlying implementation of
the commands and then wrap those in the appropriate IO.  Note also
that it is ambiguous as to whether or not the CommandProvider implemenations
are intended as generally useful API or simply one bundle's way of hooking
into the console mechanism.  So use of these command providers directly
as the underpinnings for Web UI or JMX implementations is, IMHO, questionable
regardless of -console.

- The Equinox console as it is today
is destined to change.  We are not happy with the flat command structure
and a few other things.  We'll likely pitch it for 3.4 and use something
else.  Perhaps an existing console from Felix of Knopflerfish or ...

- wrt -console itself, it should be
possible, at least in principle to start the console after the framework
is started.  So should be able to start Equinox without -console and
later do something to have he console start.  I believe that we did
some prototyping of this in the Equinox/PDE space.

Subject	RE: [equinox-dev] Multiple users and the Equinox console

I’m under the assumption that
the OSGi console commands are only available when the console is specified
(e.g. eclipse –console).  If eclipse is not started with “-console”,
than the commands are not registered and not available.
 
If this assumption is correct,
than these commands will only be available via web UI and JMX when Eclipse
is started with the console.  Does this have any impact on the usability
of the web UI or JMX interface to the OSGi commands?
 
Can someone confirm or reject
this assumption?

The nice thing about the built-in console is just that -- it's built into
the framework bundle and always there.  A web UI or JMX server can
be mistakingly stopped, and then there's no longer any way to control the
system. 

We do have extensive web UI's in our system that allow us to control all
sorts of things, but the console is nice to be able to fall back on.

I may take you up on that. =)
