Hello! I'm adding CTF-compatible tracing to a custom/experimental OS and have a question:
Can babeltrace2 read from a single CTF output file that contains both the metadata stream and the binary trace streams? My little trace system would like to bundle everything related to a trace into a single file, making it easier to pass around (since there's not much filesystem/network support yet). The CTF spec provides a way to embed the metadata stream in the same bitstream as the data streams, but https://babeltrace.org/docs/v2.0/man7/babeltrace2-source.ctf.fs.7/ says that the `metadata` file needs to be separate. I see that LTTng manages trace output as a collection of files, with a separate `metadata` file. I'd rather avoid writing a custom tool to find and extract the metadata stream from the full stream before passing the data on to babeltrace2 or TraceCompass, but so far it looks like I may need to. Would it be appropriate to add support for this to babeltrace2-source.ctf.fs? Or would this warrant a new source.ctf plugin? If I'm going to write some new code to handle this situation, I may as well try to add it to the project. Thank you! I'm really looking forward to benefiting from the CTF/babeltrace/LTTng/TraceCompass work you've all done over the years. :) --Dave Bort
