Flame graphs without Perl

[kud1ing]

Options to create flame graphs in Rust:

• @TyOverby's https://github.com/TyOverby/flame produces HTML/D3.js flame graphs in Rust.
  • https://github.com/TyOverby/fireplace
• @jonhoo's https://github.com/jonhoo/inferno

Other options:

• https://github.com/jlfwong/speedscope
  • https://github.com/jlfwong/speedscope/wiki/Importing-from-custom-sources#speedscopes-file-format

@kud1ing I've actually been working on a new project for flamegraph visualization here
https://github.com/TyOverby/fireplace

Example of a simple flame graph being visualized:

After working on it for quite some time, I found https://www.speedscope.app/ and it's better in almost every way. I'm going to work on getting bincode to export to something that speedscope can read.

I also love speedscope. This issue should be relabeled "support speedscope format" or similar.

It appears that https://www.speedscope.app supports performance logs as output by e.g. https://github.com/evanhempel/python-flamegraph (and compatible with https://github.com/brendangregg/FlameGraph).

Adding option to dump raw performance logs will provide a #45 and is a very low-hanging fruit.

Hi! speedscope author here. FWIW, while the stack collapse format output accepted by brendangregg/FlameGraph does indeed import successfully into speedscope, you'll get a higher quality import complete with filenames and line numbers if you target speedscope's own file format.

More information here: https://github.com/jlfwong/speedscope/wiki/Importing-from-custom-sources#speedscopes-file-format

I contributed support to rbspy to output to this format: rbspy/rbspy#161

Once some way of importing into speedscope from py-spy exists, regardless of what it is, please let me know and I'll update speedscope's own documentation to list it as supported 😄

I would also be happy to be able to use py-spy without having to first install perl in my Docker containers.

That latest PR removes the need for perl: #114.

I also totally agree that getting speedscope support in here is worth doing. I've created a new issue to track #115 - thumb it up if you think I should prioritize

[benfred]

fix is in v0.1.11
