src,lib: make ^C print a JS stack trace #29207

legendecas · 2019-08-19T17:20:15Z

If terminating the process with ctrl-c / SIGINT, prints a JS stack trace leading up to the currently executing code.

The feature would be enabled under option --trace-sigint.

Conditions of no stacktrace on sigint:

has (an) active sigint listener(s);
main thread is idle (i.e. uv polling), a message instead of stacktrace would be printed.

Related: #24937

Maybe we should only print a stack trace if stdin is a TTY (especially if it's meant to only happen when pressing ctrl-c)?

Left some comments but nice work!

report: is the subsystem for the node-report feature, i.e. node --experimental-report … this touches a related topic, but I think it might be confusing to name it that way

Yes, this work doesn't touch report specifically in codebase. Yet I don't find a more proper subsystem here https://github.com/nodejs/core-validate-commit/blob/master/lib/rules/subsystem.js . Since both src and lib are touched in this work, neither of those one might be appropriate IMO.

@legendecas You can also use src,lib: .... 🙂 Honestly, I don’t have a better idea than that either.

I think this PR is out of WIP, ready to be reviewed thoroughly :)

@legendecas Looks like there are still issues with the postmortem tests…

I don't have any substantive opinions for this.

legendecas · 2020-01-17T02:56:17Z

Since there are no objections anymore and multiple approves, I'd tag this as author-ready.

Is it possible to extend this also for sigterm (with a separate flag)?
