Re: [tracecompass-dev] [linuxtools-dev] We would like to contribute to Linuxtools LTTng

Hello Martin


Linux Tools 3.1 has been released. The announcement was sent on the mailing list on the mailing list on September 26, 2014.


LTTng will be part of Linux Tools 3.2 which will be released for Luna SR2 (see link below).  This release will include updates for LTTng that are currently in the master branch and that were done after the 3.1 release.


Best Regards

Hi Bernd,


Thanks for the pointer, very interesting.


It looks like our 2 approaches are complimentary – our goal is being able to replace the transport/communication for trace config and upload,

and your goal appears to be re-using that functionality in other plug-ins.


We have started implementing the proposed change against the linuxtools repo since that’s where we first got a complete development environment.

We’ll keep you posted on progress, I expect being able to contribute to Gerrit some time next week.


I’m a little confused about the state of the repositories though. I see “stable-3.1” in the Linuxtools repo, but there are also TMF changes being made to “master” of linuxtools recently.

Are you planning to release 3.2 off the linuxtools repo as a bugfix release ?

And: Is the 3.1 plan accurate, it reads “29-Oct” as release date but I thought 3.1 was out already ?

Hi Martin

thank you for your interests in the LTTng Eclipse integration and Trace Compass.

RSE has been used by us as remote backend for the LTTng control UI and for fetching of
traces remotely for both LTTng traces and other types of traces (not available in
open source yet). We were asked recently by one of our users to provide a generic way
to fetch traces from various remote systems and remote locations. For that we started
to extract common functionality from LTTng Control into a new set of plug-ins (TMF-remote)
so that it can be re-used from other plug-ins. These changes are currently submitted
for review on the Linux Tools Gerrit (see and subsequent

However, your contribution is related and touches the same area.  So, I'd like hold back a
bit with our updates and not merge them to see how your contribution and the our
updates (TMF-remote) can work together. Maybe there is interest by other companies
to have such a functionality for fetching of traces remotely.

About the the project setup. As you already know the LTTng integration of Linux Tools
will move to the new Eclipse Project Trace Compass. The project is approved by
the Eclipse Foundation and the setup of the project is currently ongoing. 

The initial commit in git repository of Trace Compass was done yesterday. Gerrit and
Hudson setup is ongoing and hasn't been finished yet. Also, the project page is being
constructed right now.
Here is the link to the project page:

The source code under the Linux Tools project will be available till the Luna SR2 release
using the Linux Tools Luna APIs.

>From our point of view, our main focus will be further developments of new features
under the Trace Compass project. Beside bugfixes only limited number of features
(if any) will be added in the Linux Tools repository depending on user's requests.

How would you like to handle this contribution? Would you like to contribute it to the
Linux Tools project so that it is available for the SR2 release? Or is it an option for you
to contribute the code directly to Trace Compass and the new repository?

In any case, it will be great to see an initial version submitted on the Linux Tools Gerrit.

Looking forward to see this contribution.

Best Regards

Dear Linuxtools committers,

We would like to make a contribution to Linuxtools / TraceCompass:


Is there anything we should know upfront ? – I’d expect our contribution to be available some time next week.

Please let us know of any questions.
