Hi, I had a brief discussion today with Jeff Johnston on the IRC channel today. I had been experimenting with the new Valgrind support for remote launch via RSE connections. I ran into a strange problem and it turned out to be because I had misunderstood the intent of the remote launch capability, that it is designed for a "cross-compile/link, download executable, remote launch Valgrind" workflow, rather than a "remote build, remote launch Valgrind" workflow. Knowing this allowed me to understand why the dialogs didn't allow me to choose an executable residing on the remote machine.
To take a quick step back, we in IBM toolchain team are wanting to use remote Valgrind launches in the "remote build, remote launch" workflow. The Eclipse PTP project already has some nice support for remote builds, remote launch, and remote debug (though remote debug requires an intermediary process called SDM). The usability of PTP connections, in my opinion, is much cleaner than that of RSE. RSE requires manually starting the RSE server on the remote machine, opening holes in the firewall, etc. PTP uses ssh connections to communicate with its dynamically downloaded java-based dstore daemon. All of its communication goes through ssh, so no firewall hole poking is needed. What is needed on the remote side is to install Java and sdm (sdm is needed only for debugging). One thing I didn't mention about setting up PTP, is that in order to launch a remote executable, debug, profile, etc., you need to start up a "Resource Manager". Fortunately this is easy to do. There are a number of Resource Manager types to choose from, and the generic "Remote Launch" resource manager works just fine for single remote host setups. What do you think of utilizing PTP for adding remote build, remote launch capability to the Linux Tools Project plug-ins? There's been a lot of work and refinement that's gone into PTP over the years, and I think Linux Tools could benefit from it. We could structure it so that the remote build, remote launch are separate features that people wouldn't have to install, if they didn't want to install PTP when they install Linux Tools. If you haven't played with PTP before, there's a nice tutorial here: http://download.eclipse.org/tools/ptp/docs/ptp-sc10-tutorial.pdf - Corey _______________________________________________ linuxtools-dev mailing list linuxtools-dev@eclipse.org https://dev.eclipse.org/mailman/listinfo/linuxtools-dev
