Re: [ptp-dev] Question about running additional commands in external tools framework
|
Dave,
Here's what you need to do to get the hostname from a resource
manager. In the case of a serial connection, it will depend on how
you've implemented the connection. If you're using RSE then you'll
need to explore the gory details of RSE to find it. You might find
some useful code in the org.eclipse.ptp.remote.rse.core plugin.
Cheers,
Greg
1. First, get the resource manager configuration from the resource
manager:
IResourceManagerConfiguration rmConfig = rm.getConfiguration();
2. Check that the resource manager configuration is derived from an
AbstractRemoteResouceManagerConfiguration:
if (rmConfig instanceof AbstractRemoteResourceManagerConfiguration) {
...
}
3. If it is, use the remote services ID to get the remote services
used by this RM:
AbstractRemoteResourceManagerConfiguration remoteRMConfig =
(AbstractRemoteResourceManagerConfiguration)rmConfig;
IRemoteServices remoteServices =
PTPRemoteCorePlugin
.getRemoteServices(remoteRMConfig.getRemoteServicesId());
4. Then use the remote services to get the remote connection:
IRemoteConnection connection =
remoteServices
.getConnectionManager
().getConnection(remoteRMConfig.getConnectionName());
5. Finally, use the IRemoteConnection to get the remote address:
String address = connection.getAddress();

I tried coding another analysis step as you described and it seems
to get control at the right point in time. I'm not sure how I get
the host that I run the command on though. If I look at the
attributes in the ILaunchConfiguration obejct my method is passed. I
don't see a remote host name in there. The closest I see is the
attribute for a resource manager id. I can find the resource manager
by starting with the array of resource managers obtained bt
referencing the PTPCorePlugin object, but I don't know how I get
from resource manager to the hostname of the connection for the
remote connection. I'm also not sure how I make this work in the
case of a serial application where I don't think I have a resource
manager to deal with.
The other thing that's happening now, and may have been happening
all along, is that I see my parallel application running twice when
I run the performance configuration. I'm guessing once because of
the application tab in the performance configuration and then again
for something in your extension.
Any idea what might be happening?

Re: [ptp-dev] Question about running additional commands in
external tools framework
The behavior of utility commands in an execution step is different
from the analysis step. In the execution step they are supposed to
compose with the application being run. This is to support tools
like valgrind where you actually run valgrind and give it your own
executable as an argument. This means that your setup should have
sent a command like
/bin/touch /tmp/plugin <your_executable>
...to the remote machine which is still not what you want. But it
sounds like the framework didn't make it that far. The system does
some error checking which includes making sure the path exists on
the local system, which I will need to remove to support remote
functionality. This same error checking currently looks at the
whole string for the utility command to see if it is a valid file.
If you put /tmp/plugin as an <argument value="/tmp/plugin"> to the
utility, so the command string is just the executable it will get
around that. But this still doesn't address your goal.
Right now the best way to run an arbitrary application is with the
<analyze> tag. I need to enable remote support for you to be able
to invoke remote applications with simple xml, but as a temporary
measure you could specify another internal analysis step with
AbstractPerformanceDataManager that uses the remote API to invoke
'touch'. You would need to put that analysis tag before your
execute tag so it might bug you for the execute directory as you saw
before. I'll add an attribute to tell it that it doesn't need to do
that. And I'll try to implement some basic support for remote tool
invocation so that kind of effort won't be necessary.
Another possibility would be to use two execute commands in a row.
The second is your regular command. The first is just:
<execute>
<utility command="touch"/>
</execute>
This will touch (not launch) the executable itself so you can check
its time stamp. ...except, it will use whatever run job parameters
you have already set up with your remote resource, which might not
be appropriate.

I'm wondering if there's a way to run additional commands prior to
running
my application using the performance configuration dialog and your
framework.
I tried putting
<utility command="/bin/touch /tmp/plugin"> statement in my XML file
thinking that would run the touch command on the remote system. I
ended up
getting a popup telling me the '\/bin/touch /tmp/plugin' tool wasn't
found
so I'm guessing this was run on my local system and failed.
Is there a way I can run a remote command before running my
application
using your framework that doesn't require the user to do anything? Is
there something I can code in the XML file to do this?
If not, I'll have to think about a different way to solve this since I
think this is very specific to my plugin. I'm trying to touch a file
to
use as a timestamp so I can find files created later than the date
of the
file I touched. I can't rely on time o the local system since clocks
may
be out of sync.
