Re: [tracecompass-dev] Inquiry about writing xml analysis file

Thanks for the reply kindly, Matthew.

I'm going to look at the bugzilla you mentioned. I hope tracecompass to be famous and used widly as perf. I hope to contribute it if I have time to look at a code.


Thanks and regards,
Changhee

Hi Changee,

I apologise for the late reply.

1- I checked, and we do not support experiments or trace sets yet with XML views. This is an interesting feature we do have it in the pipe for later. It should be in trace compass 2.0, but if you have any suggestions on how to do it, we are very open to input. (and patches, :))

2- A single message on the timegraph: I am assuming you mean like a label on the timegraph entry. This is also not yet supported.

3- Pattern matching event providers. This is also super interesting and important, it is done in KernelStateProvider.java now but it is not yet supported in XML. I would love to give you an eta on when we will implement these features, but at this moment the answer is soon, but not yet. :(

Thank you for your interest in the project. One suggestion I would have is to open bugs in the bugzilla for the three features. That way you will be mailed the second (maybe minute) that the features are merged.

I hope to hear from you soon,

Matthew
