rbspy

• Add support for Ruby 3.0 (#285)
• Upgrade remoteprocess and proc-maps crates (#295)

• Fix special variable handling when resolving C functions (#291)
• Fix flaky subprocess test (#290)
• Fix several build warnings

This release includes a very exciting feature implemented by @acj from #282: resolving C function names! This was requested a few years ago in #110.

Here's what rbspy record on the example infinite.rb program in this repo looked like before this feature:

Summary of profiling data so far:
% self  % total  name
100.00   100.00  <c function> - unknown

and here's what it looks like now:

Summary of profiling data so far:
% self  % total  name
 99.54    99.54  <c function> - sleep
  0.31     0.46  <c function> - require

This version should have M1 support, thanks to #280 and #281 by @petethepig.

For now there's no compiled artifact for M1 (CI doesn't support it yet), so you'll need to compile rbspy for M1 yourself for now.

• add support for ruby 2.4.10 and 2.5.2 (#272)
• add support for ruby 2.7.2, (#271)
• add timestamp weights to speedscope output format (#253)
• say that rbspy isn't an on-CPU profiler

Adds a new output format -- https://www.speedscope.app/'s format, which lets you visualize profiling data either in time order (see exactly which functions got called when!) or as a regular flamegraph. Thanks to @jlfwong, the Speedscope author, for contributing this!

This release brings Windows support to rbspy, thanks to the incredible efforts of @benfred (a first time contributor!!!!). Thank you!

Thanks to @tcaddy for contributing this!
