I've done a small straw poll from a range of ages (20's to 70's). Only the older people (60's+) seem to have vaguely heard of it but none knew what it is or had any particular reaction to me mentioning it. Note though th

I mean, Vista is ~15 years old at this point. If anything that's still part of Windows makes the backspace mistake then if nothing else it's impressive it's survived this long without being noticed.

No, it's UTF-16 with no validation at the kernel level. Invalid UTF-16 is also invalid UCS-2 as those code points were explicitly barred from use. In practice, only malware will create such broken names. High level software (e.g. Micro

Sure. I did not mean to imply that SEH itsef requires the C runtime. However, the __CxxFrameHandler3 that Rust/llvm uses would need to be rewritten. IIRC llvm itself generates calls to __CxxFrameHandler3 when SEH is being used, making

At a minimum Rust would have to run the C initializers as these are used even in pure Rust code. It might also make use of the security cookie but I'm uncertain about that. Also the C runtime is needed by the SEH handling code (in vcru

Rust needs the C runtime for startup/shutdown code (and vcruntime for panics). It also needs basic memory functions such as memcpy and stack probes. There is no way round this except rewriting those in Rust.

A string is encoded in memory as an array of numbers so in this case "ordinal" means that it simply compares the two arrays number by number. A non-ordinal string comparison may take into account other things such as iterating by

It does not. Invalid UTF-16 (aka unpaired surrogates) are replaced by the Unicode REPLACEMENT_CHARACTER (�) However, in practice such filenames are only produced by malicious software and many large products won't work with them anyway

UTF-32 was an interesting choice. Was that done for the sake of completeness or was there a specific use case for it?
161.
by ChrisSD 5y ago
The Rust standard library has contortions in order to support invalid UTF-16. To do this it uses an encoding called "WTF-8"[0], which is an extension to UTF-8. If the standard library dropped this requirement and only supported va

You would need libraries. E.g. the C runtime and system import libraries (msvcrt.lib, vcruntime.lib, kernel32.lib, etc).

Ken Thompson was the one scribbling on a napkin. Rob was the one telling the story later on.

Thanks! That's super helpful.

While you're here, do you happen to know if mingw will gain support for native thread local storage? Emulated TLS is still the only option, right?

Eh. They're basically right. Windows "11" is just rebranding. There's no reason why it couldn't have been a Windows 10 feature update, except that they wanted to drop support for older hardware.

Eh. Tbh I'm find both powershell and unixy shells have their advantages and warts. I'm not sure either is "better". Maybe I'm just not a fan of shells in general.

by ChrisSD 5y ago
`vswhere` is for querying a variety of information about all visual studio installs. It does far more than the "simple" problem of finding libraries.

If they were doing conversions manually, I suspect such a major encoding error would have shown up quite quickly. It's bound to cause errors when a file is unopenable in a lot of programs that can't handle non-unicode (heck, Micro

Windows is actually quite a bit better. The APIs require you to use an encoding. The multibyte `A` APIs can be whatever encoding the current process is using and will be automatically converted to valid UTF-16. The `W` APIs are for UTF-16.

Huh? The NHS COVID Pass does. It allows sharing vaccine status in both domestic and international contexts.

by ChrisSD 5y ago
You have the right to choose. A passport gives others necessary information so they can choose. Managing public health is difficult enough even without people forcing their choices on to others.

If the crate is actively malicious then crates.io should be informed immediately and the crate removed. Probably the author too. If need be RustSec can issue a security advisory.

by ChrisSD 5y ago
These do all seem to be things that apply to most package managers of this kind. So it would be good if Rust could find solutions that can be applied more broadly.
