Well the biggest goal was to be useful. Nginx serves ~20% of the web, memory unsafe languages might just become untractable for critical exposed to the web infra if the rate of critical CVE's on these rises faster than they can be patched, so a drop in replacement would be a big deal in that world. But in terms of learning I'm learning relatively little about how to type Rust into an editor but a lot about how to set…

Buddy, I think it is time to not engage with these models for a bit, you seem to have lost your mind.

We're literally in a thread on converting legacy C projects to idiomatic Rust? It seems many people are working on this same problem.

Yeah I got one, why? You aren't learning anything, you are just copying code from other codebases and smashing it together to make some nginx-rust thingie... for what actual goal?

You mean you rewrote the nginx test suite with smaller leaner tests ? How did you bootstrap that ? How do you know the leaner tests are equivalent to the real ones ?

There are plenty of Rust based reverse proxies out there, why do you need to specifically rewrite nginx? You could also write a config adapter to Caddy, there are a billion options, but this is a wasted effort. The people who want to stick to their nginx configs won't use your project ever, and the people who actually care about security aren't going to use a vibe coded project.

I have no idea why you are making me spell this out, I thought it was pretty obvious.

Does anyone plan to use this? Similarly, is there any momentum left for Cloudflare's EmDash? I can barely find any discussion after April.

Wordpress is/was successful because it's braindead and has a solid userbase. I am not to flame WP, but it's a quality to target a specific group of consumers.

It's an organic success, hard to replicate. If at all, CF can only make people migrate with massive effort. Marketing effort, selling lots of snake oil in the process. WP wont just hop on the hot new thing, WP is the definition of the opposite. It works for them. Why change.

Git is the same on the other side. It requires maintenance and improvements, surgical and correct. No git maintainer has time to learn a gigantic new codebase and they will stick with what works for them. For git users there are no advantages. So similarly it would require a long time effort to push the project, building trust that it is somehow better, probably requiring Linus to say "it's great".

This is coming from a cofounder at github, someone who probably knows precisely what the GPL is for. Whatever the legal merits, building on a GPL3 project's complete test suite and relicensing under MIT is not acting in good faith toward the original authors. I really find it disgusting and it makes me want to avoid gitbutler entirely.

I think you're saying that you don't believe in the freedoms to use the GPL licensed test suite for certain purposes which are explicitly allowed by the GPL.

You don't get to choose a license and then add extra terms to it when you don't feel like it's up to scratch. That's something explicitly not allowed by the GPL license.

> The full build of all Git functionality in Rust is currently around 27M, but since a large part of it is a library, it could clearly be easily split up into domains of functionality - subcrates that do specific things.

I downloaded v0.3.99 for Linux x86_64 and stripped the binary. It ends up at 31 MB. The .text section is 25 MB.

I'm surprised by the large size. On my system /usr/bin/git is 4.7 MB, although git is split up into multiple programs. I'm not comparing apples to apples, but this is weird.

If anyone digs into the binary size, please share what you find.
