wine VS linux

Sometimes when a detail of Windows isn't documented, the Wine source code can be useful. Have you tried looking at it for details of win64 SEH? For example:

https://github.com/wine-mirror/wine/blob/master/dlls/ntdll/e...

https://github.com/wine-mirror/wine/blob/master/dlls/msvcrt/...

Source code: https://github.com/wine-mirror/wine/tree/master/programs/wor...

It's Wine with some special sauce (Apple couldn't reuse VKD3D because they chose to invent Metal rather than stick with OpenGL/Vulkan so they had to build their graphics translation themselves). Crossover is built on the same technology. In fact, Apple's brew script literally links to Crossover's sources: https://raw.githubusercontent.com/apple/homebrew-apple/main/...

Things like the crypto API should be implemented if you can find the reference for your specific API calls here: https://github.com/wine-mirror/wine/tree/master/dlls/crypt32

Apple's version of Wine is aimed at developers, though. It shouldn't take too long for someone to make an app or script to easily set up environments with the developer runtime, but I doubt they'll support it as well as Valve supports Proton. If your application of choice doesn't need any fancy graphics, there's a decent chance Wine/Crossover can already run it anyway, no need to mess with Apple's SDK.

With the M2 Max outputting 28fps at 1080p (screenshot linked), I wouldn't expect too much from the gaming performance of this thing, though.

Not the OP, but Github's stats on https://github.com/wine-mirror/wine say the current Wine codebase is 95.1% C, 0.3% C++

Take a look at Wine's commit log. It's really well curated. https://github.com/wine-mirror/wine/commits/master

Fixes Overwatch 2 game freeze after a few seconds in game. After a long bisect it was found that wine-mirror/wine@4bf9d24 from upstream wine wine 7.13 and higher needed to be backported.

git clone https://github.com/wine-mirror/wine \ cd wine \ ./configure \ make \ make install \ wine ./Anomaly.exe

Well, I personally can't confirm nor deny that (the only "old" game I play is Plants vs Zombies (2009), and surprisingly it still works great with latest Proton). But the reality is that Wine/Proton are very large and complex projects, developed by pretty much just reverse engineering Windows; Couple this with the fact that a lot of changes happen in-between versions (especially in Wine), and even though an one-line change fixes an issue, it might end up breaking something, elsewhere. My point is, it's almost inevitable not to break stuff eventually. This is why Valve gives us older Proton versions to choose from.

FFS predates FreeBSD and is in some capacity supported by all 3 major BSDs. I'm fairly confident that Linux actually supports it through the ufs driver ( https://github.com/torvalds/linux/tree/master/fs/ufs ); whether the use of different names in different places makes it better or worse is an exercise for the reader.

These are a bit easier to see what's going on:

https://github.com/torvalds/linux/blob/d5cf50dafc9dd5faa1e61...

Unfortunately Github doesn't have a way to render symbols for whitespace, but you can tell by selecting the spaces that the previous version had leading tabs. Linus changed it so that the tokens `default` and the number e.g. `12` are also separated by a tab. This is tricky, because the token "default" is seven characters, it will always give this added tab a width of 1 char which makes it always layout the same as if it were a space no matter if you use tab widths of 1, 2, 4, or 8.

There was also a Gentoo effort to run atop FreeBSD[0]. The challenge of course is that afaik none of the BSD kernel ABIs are considered stable. The stable interface is the BSD libc. That said, with binfmt_misc, I don't see a reason you couldn't just run (at least some) FreeBSD binaries on Linux with a thin syscall translation layer (rather something like qemu-system) and then your layer hooked via binfmt_misc. I'm not aware of anyone who has done this for FreeBSD, but prior efforts existed as alternate binfmts for SysVr4/5 ELF binaries[2]. Either way would take some elbow grease, but you *might* even be able just reuse binfmt_elf and just have a new interpreter for FreeBSD elf.

> The original less-than check was deemed incorrect

It was only deemed incorrect because of an information leak. Not because it's a valid use-case for user space to copy smaller portions of *hwrpb into user space. https://github.com/torvalds/linux/commit/21c5977a836e399fc71...

Correct. And the combined work needs to carry the MIT license text and copyright attributions for the MIT software authors. With binary distribution it must also be overt, not hidden in some source code drop, but directly accompanying the binary.

Many people who talk about relicensing never credit the MIT developers or distribute the MIT license text. "Because it's GPL now."

I don't think that you believe that, but many developers do.

Some don't see the need for source code scans for Open Source compliance, because the license.txt says GPL, so it's GPL. Prime example is the Linux kernel. There is code under different licenses in there, but people don't even read https://github.com/torvalds/linux/blob/master/COPYING till the end ("In addition, other licenses may also apply.") and conclude it's simply GPL 2 and nothing else.

Also be aware that sublicensing is not the same as relicensing.

He notoriously hates GNU Emacs, yes.

So If we would only count code and not comments, it is only 9489 LoC Rust. Which would be about 0.03% and if we take all lines and not only LoC it would be around 0.05%
