RE: [linuxtools-dev] LTTng - no display

["George Stephen-RVGG20" <RVGG20@xxxxxxxxxxxxx>]

I have continued to work on my display issue and discovered that if I
limit the marker types that are enabled when I capture the trace I can
produce traces that seem to work. I have been trying to narrow to a set
of markers to illustrate the problem.

I have a trace file that fails (with a NullPointer exception) that was
created with only the kernel-trap_entry and trap_exit markers enabled.
This trace is viewable with lttv-gui but crashes LTTng. 

Can I send the trace file for someone to look at or should I enter a
Bugzilla item?

Thanks,
Stephen

William should be able to provide you with the exact version to download
but it will have to wait until Monday AM.

It was not our initial intention to support older versions of the trace
format but, if the need is there, we will definitely prioritize it.
Anyway, we do have to support upcoming versions which boils down to the
same issue. It would just be implemented earlier :-)

And yes, we would like to provide format support from a single
liblttvtraceread.
