pyroscope-rs VS cosmopolitan

A general purpose profiler: https://github.com/pyroscope-io/pyroscope-rs

If someone is interested in this space, feel free to reach me!

I feel some of the OP points. I was working on a profiling agent lately, and one of the issues was running it on multiple platforms (just the four big ones linux/mac-x86/arm) on FFI (because it'll be run directly from python/ruby/etc...) and preferably having the thing just work without having to install or configure any dependencies.

Like OP I hit two walls: libunwind, and linking. For libunwind, I ended up downloading/compiling manually; and for linking there is auditwheel[1]. Although it is a Python tool, I did actually end up using for Ruby (by creating a "fake python package", and then copying the linked dependencies).

It was at that time that I learned about linking for dynamic libraries, patchelf and there is really no single/established tool to do this. I thought there should be something but most people seem to install the dependencies with any certain software. I also found, the hard way, that you still have to deal with gcc/c when working with Rust. It does isolate you from many stuff, but for many things there is no work around.

There is a performance hit to this strategy, however, since shared dynamic libraries will be used by all the running programs that need them; whereas my solution will run its own instance. It made me wonder if wasm will come up with something similar without affecting portability.

Finally, the project is open source and you can browse the code here: https://github.com/pyroscope-io/pyroscope-rs

Version 0.5 is now live!: https://github.com/pyroscope-io/pyroscope-rs

Working on https://github.com/pyroscope-io/pyroscope-rs A profiling solution for Rust and other languages.

Thanks to the maintainers at pprof-rs for helping us figure out how we can modify their profiler to create our rust agent (https://github.com/pyroscope-io/pyroscope-rs).

The reality is a bit different, the work on Python 3.6 was checked into the Cosmopolitan repo and I have been able to use it for production workloads that are in pure python. [0]

As Cosmopolitan Libc has evolved, it has been possible to compile more software without modifications, and that includes latest Python through a project called superconfigure[1].

Last person who tried to reproduce it from scratch did it last week (granted it too them a few days of solid work) but in the end they ended with a portable binary with Python 3.11.9, brotli, ssl and asyncio for their work related project.[2]

Some genius realized that you can actually embed valid win32 programs inside valid posix shell scripts, and found a way to make a C cross-platform solution out of it, meaning that you can write C programs that compile to a single executable that will run on (quoting the site) Linux + Mac + Windows + FreeBSD + OpenBSD + NetBSD + BIOS

It all started from this post.

For this .args file, put one argument per line. This will run on start. You can use `/zip/mydepencency.anything` to read from files, but if you have an executable dependency you'll need to extract it first.

You can do this with any software you can compile with comsocc, by adding a call to LoadZipArgs[1] in the main function.

It'seasy to get started, your ideas will branch out as soon as you start playing with it.

FWIW there is ongoing work with good progress to add websocket support to redbean (https://github.com/jart/cosmopolitan/pull/967)

it might help but not sure how comprehensive it is! would it be a bad idea for you to check out the source code of other popular emulators (maybe iTerm 2^0) ?

The binary was compiled with Cosmopolitan Libc [0], and therefore the binary will execute natively on Linux, Mac, Windows, FreeBSD, OpenBSD, NetBSD, and bare metal (BIOS boot).

I would call that portable.

will go on my "to try" list where i already have cosmopolitan [2]. my last setup (windows) was shiv + wine + nsis (used that as pyinstaller had some issues)[2]
