tracing-framework/bin/query.js: support per-thread queries

[vertexodessa]

I'm able to dump events from .wtf-trace file generated by C++ application:
tracing-framework/bin/query.js tmptestbuf.wtf-trace /./
However it's not clear if there is a way to dump events generated on threads different from the default one.
Could you please advice about that?
Appreciate your response.

I haven't looked at that side of it in quite some time and will be to check when I'm at my computer. If it helps, each c++ thread is mapped to a "zone" in wtf parlance, so if you see something that lets you select zones, that is what you are looking for. Also make sure you have used some variant of the WTF_THREAD_ENABLE macro for each thread that you wish to generate a zone for. Let me know if neither of those things help and I'll look further when I've got a few minutes later this week.

hi Stella, thank You for Your replies! I'm sure there were multiple threads, I can see them in Web UI. However I couldn't find a way to select a different one using query.js. Would appreciate if You or someone could give a hint.
Sorry for sparse replies, I'm currently having some free time to look mostly at the weekends.
Please let me know if you want me to attach the wtf-trace file.

P.S. the reason I'm interested in dumping the events using console without WebUI, is that I'd like to try blacklisting functions automatically based on their execution time and count (https://github.com/vertexodessa/iitracer/blob/8b17ff2144f5534d005ee8ccdedde7c096e4049a/lib/src/iitracer.cc#L25).
