I did an executive summary of things we presented and other interesting
stuff from TracingSummit/LinuxCon last week.

I used Eclipse Memory Analyzer (MAT) to find the object holding a reference
to a large temporary chunk of memory. It appears that TmfExperiment is not
AutoClosable as other traces, and calling dispose() method on the

I just upgraded to Ubuntu 14.04, and when using the TMF RCP product,
widgets are crippled. I had to set the environment variable SWT_GTK3=0 to

I'm a fan of test driven development, and to be productive and engaging,
the feedback of running one unit test should be quick (let's say, under a
second). However, running a blank plug-in unit test function takes about 15
seconds on my machine (recent i5 CPU, 8GB RAM, SSD drive). Is there some

Seems that these two dependencies are required to build the new gdb stuff:
CDT Common GDB Support
C/C++ DSF GDB Debugger Integration
I can update the documentation accordingly if I get the confirmation that
this is indeed correct.

Hi,
There seems to exists inconsistency in CTFTraceReader timestamps.
* getStartTime() returns a raw timestamps
* A call to getEndTime() after object instantiation returns a raw
timestamps equals to start.
* After reading an event, getEndTime() returns the timestamps + offset
of the trace.

I do maintain a traceset here (on a 8 cores system):

Ok, got it. That was stupid. It works if the option "Include required

Then select "LTTng - Linux Tracing Toolkit" and click Finish. I tried
other features from linuxtools and the same problem occurs. I tried
other p2 repository and it works.
Weird?

Hi,
I did a small analysis based on inventory of 125 trace events in Linux
and MariaDB (instrumented with UST). Here are some observations and
categories of events and how they can be related to states.

Hi,
I did a small prototype for CPU history average usage. You can look at
