analyze dump
As mentioned in the case #40, please consider add a feature to allow py-spy analyze dump files. Rather than use --pid pid or run live target process, add an argument for loading windows dump or core dump on linux/mac. Thanks!
this could be useful, but will only let you get a single stack trace (like the output you get from passing --dump on the command line) instead of something like flamegraphs.
fwiw, rbspy does testing like this - it grabs some core dumps and verifies that it can extract the correct stack trace from them, which is a pretty neat way of testing.
i think this would be useful. i've been thinking about using py-spy to create a thread stack dump tool,but it was a little unclear if that fit into the goals of py-spy.
Ability to do this with Linux has been added with https://github.com/benfred/py-spy/pull/538 -
