How to extract symbol files for nw (node-webkit)?

Question

As docs are saying

The symbol files (.sym) can be extracted from the downloaded packages.

As far as I understand from one of this http://nwjs.io/downloads/ or from one provided by the nw-builder. Both have the same structure without any *.sym files. And there is no clue how to extract them. Nor in the docs nor in the www.

Answer 1

stackwalk-http is a version of minidump_stackwalk that can fetch symbols over HTTP, and also has the Mozilla symbol server URL baked in. If you run it like stackwalk /path/to/dmp /tmp/syms it will print the stack trace and save the symbols it downloaded in /tmp/syms. Note that symbols are only uploaded to the symbol server for nightly and release builds, not per-change builds.
