Is there a list of CMD builtins somewhere?

In the case of find and sort, the command invoked also depends on argument sniffing, with a fallback through the registry when that is indecisive: https://github.com/microsoft/coreutils/blob/main/src&#x2F

The method is called `CoherentAllocation::into_parts`. And it takes self by value, which means the struct is consumed (this is implied by the into_ prefix). Of course you would either reconstruct the allocation or free the allocation your

> will they abdicate their power Yeah, no. This is a coup and they are all in. They would not be this blatant about taking control illegally and fast if they expected to leave any institutions to still enforce the law against them.

Looks like the Steam team moved to control spawning and do execvpe. I would like to see at least in-process environment modification discouraged. Rust is dealing with the issue by considering getenv unsafe when coming through C, but gettin

It is possible to check for setenv/unsetenv/putenv with nm -D, and a quick sample of my ~/.cargo/bin/* shows far too many programs using those. Yeah they could be single threaded, but who can guarantee they will re

I've had my own bad experiences with Btrfs (it doesn't behave well when close to full), and my intuition is that Facebook's use of it is in a limited operational domain. It works well for their use case (uploaded media I thi

> Error handling on CRC read error > 2 or more copies of file, CRC on error, read other copy, data returned to userspace, does not correct bad copy That's been implemented; in Linux 6.11 bcachefs will correct errors on read.

The Into<SpanArithmetic> argument feels a little too magical. Since you are not constrained by a trait, I would prefer something like Span::add_with_reference(&self, other: &Span, reference: impl Into<SpanRelativeTo&g

Emergency braking feels more like shoving the wheel forward than shifting oneself behind the wheel. You ignore balance for a while, get yourself into a sitting position fast, the system can right itself (or not) after you've bled enou

There are two level of pointers: the environment block points to an array of pointers to C strings, this higher-level pointer can be updated and the previous one freed, which is a problem when it is being iterated on (which getenv does). T

Who doesn't? libc itself calls getenv when getting system time: https://news.ycombinator.com/item?id=38344224 You may have a mutex on getenv/setenv, like the Rust stdlib does, but when libc doesn't look at t

kernel developers are free to factor in common functionality, calling into it library style, without making it into an externally visible layer. IIRC fs encryption and case insensitivity are often done that way, and I think I'd count

Of course bcachefs can cache data; that was the main draw of bcache as well. Quoting an example from https://bcachefs.org/GettingStarted/ bcachefs format /dev/sd[ab]1 \ --foreground_target &#x2F

I was thinking of that around the "stack-based interpreted language" paragraph. Mozilla's RLBox/wasm2c approach would be good for this, for example. Postscript can still mix data and code, but it won't jump outside

Some popular proc-macros could be pre-compiled and distributed as WASM, and it would be impactful, since they tend to bottleneck the early parts of a project build. However I don't think that could be made entirely transparent, becaus

I don't see why you'd blame Linux for deleting a file you asked it to. However, if the process is sufficiently long-running, it is possible to relink the file by looking inside `/proc/$(pgrep yourprocess)`.

As far as I'm aware (ICEs…) compilers aren't hardened against untrusted code, and a sufficiently capable exploit could be used to poison the cache.
