[lttng-dev] [RFC PATCH 0/2] babeltrace legacy LTT 2.6 converter

Hi list,

I've written a converter that can read LTT's 2.6 trace format and convert it
to a CTF trace format. This was discussed before on the list:


and I roughly followed the guidance given by Mathieu there. Roughly because
I did not create plugins but followed the approach of babeltrace-log.

How it works:
- babeltrace legacy converter gets a directory containing a LTT 2.6 trace
  and a target directory where it will create the converted trace
- it scans the metadata_N files and creates a CTF which fits the old trace data
- it scans all trace files and creates CTF headers but copies the trace data
- empty files which contain only headers are not copied

Is there any interest in picking up this code for babeltrace (or is it just
too obscure :) ?
