trickle VS fish-shell

This method could apply to other tools with the same IPv4/IPv6 behaviour, without further modification. Changing the behaviour in the utility directly would only fix it for that one utility meaning that to fix another you need to do the same work again. It is perhaps also safer than modifying such a core component as SSH: if you introduce a bug the trick can be easily disabled until fixed, if you accidentally break SSH you might cause yourself significantly more hassle.

> This sort of negates that advantage

LD_PRELOAD trickery doesn't negate the advantage of having full source access, patching SSH would also have been a perfectly valid option, but is perhaps a better tool for this particular job.

For another use of the trick see https://github.com/mariusae/trickle (the project looks stale, though that may be because it is properly done and there have been no security/other bugs to fix in recent history) which slips its own functions in the call chain to apply user controlled (rather than firewall/routing level) throughput shaping to utilities that don't offer it out of the box.

Have you tried Trickle?

Assuming you're on Linux you could use something like Trickle: https://github.com/mariusae/trickle

install trickle

Reminds of the note at the bottom of Fish's releases. It's there because the build system cannot determine the current version for some reason. Hopefully that will go away now that they have switched to a different language / build system. The custom tarball is used by Arch Linux at the very least.

A recent practical example of the former: the fish shell re-wrote incrementally from C++ to Rust, and is almost finished https://github.com/fish-shell/fish-shell/discussions/10123

An example of the latter: c2rust, which is a work in progress but is very impressive https://github.com/immunant/c2rust

It currently translates into unsafe Rust, but the strategy is to separate the "compile C to unsafe Rust" steps and the "compile unsafe Rust to safe Rust" steps. As I see it, as it makes the overall task simpler, allows for more user freedom, and makes the latter potentially useful even for non-transpiled code. https://immunant.com/blog/2023/03/lifting/

And this discussion from November has an update on the progress: https://github.com/fish-shell/fish-shell/discussions/10123

We're using bash as our terminal shell for now (it is standard in many distros) but it is not the only one out there. If you want to test out zsh, fish or oh-my-zsh, you will see that there are a few differences and the features are usually the main differentiator. Try that, poke around.

They have a variety of reasons to move to rust, as outlined in their original rust discussion[1]. Mostly around finding other contributors, and adding an async/parallel mode they're comfortable with.
