Re: [linuxtools-dev] remote Valgrind
|
Hi Corey,
Yes I have seen that bug. It goes away IIRC and I thought I had checked
in a simple patch to verify
that the offending line doesn't try to access a null object, but
apparently I did not.
I got the remote Valgrind stuff working over TCF, but I had to apply
some tape to make it work with an actual remote system. Running it with
a local TCF agent works quite nicely but that really isn't the point of
using the remote launcher.
At the moment I am rewriting the RemoteTab/RemoteConnection classes to
deal with RSE hosts rather than TCF connections so the code won't know
anything about TCF. This will make the code much more generic and allow
more flexibility in the set up (e.g. you can start a tcf-agent or use an
rseserver, etc..). The code only requires that there be a File
Subsystem and Remote Command Subsystem at the moment.
I am currently testing the rewrite but ran into some issues on my laptop
(can't restore my F14 VM which has my tcf-agent set up and trying to
test with local RSE fails because the executable flag is not being set
for the executable when it is uploaded).
If you would like to try it out, I can send you the files.

Hi Folks,
I thought I'd have a look at the current state of remote Valgrind.
Would you expect that it should work straight out of the Git tree? I
ask because I am seeing an NPE.
I set up an example project using a TM/TCF connection to my laptop (from
the same machine). I then created a small executable and compiled it
successfully.
I right-clicked on the resulting executable, and selected Profile As->
Profile Configurations... I then selected Profile with Valgrind
(Remote), and clicked the "new" button above.
I then got an NPE (see below) during the building of the Remote Tab,
which appears to be because the "peers" list is empty. Why this is, I
don't know. I would think the peers list would at least contain the
TM/TCF connection being used for the project.
Has anyone else here had success with Valgrind Remote?
