Implemented chcpu

[koutheir]

Closes #22.

[koutheir]

@sylvestre, this is util-linux. Why is the CI server attempting to build it for Windows and MacOS?

[koutheir]

I just noticed PR #226. I don't intend to trigger any conflicts. @sylvestre, how should I proceed?

[sylvestre]

@koutheir could you please contribute to the other PR ?
for example, it doesn't have test
wdyt?

Does that mean abandoning the code of this pull request?

[sylvestre]

i haven't looked which one is the best implementation
maybe we can merge the two?

[koutheir]

I actually read the code of the other pull request, and given the significant difference in design decisions, I don't think the two PRs can be merged, without overriding most of the code of either implementations.

[sylvestre]

OK. Too bad.
I didn't look at the feature scope but in general the first wins.

[sylvestre]

I will have a deeper look

[koutheir]

@sylvestre, did you get a chance to look deeper?

[sylvestre]

not yet, sorry

[sylvestre]

could you please fix the build failure on other OS ?
I'm prefer this implementation because it offers superior modularity with better organized files and robust error handling.

[koutheir]

could you please fix the build failure on other OS ?

Should I remove the Windows and MacOS entries from the CI configuration?

[sylvestre]

nope, fix your PR to make it pass on these archs (as much as possible)

it was green before: https://github.com/uutils/util-linux/actions/runs/13933228399

Do you mean port the tools to these platforms? Or somehow exclude the tool from building? Or make it an empty crate?

[sylvestre]

As much as possible, we want to support other OS. Here, i don't know if there are API to do the same on Windows and Mac

[koutheir]

For reference, these tools (util-linux tools) are very Linux-specific, relying on Linux-only APIs and mechanisms. Porting them even to other UNIXes is tricky. Porting them to Windows too will make the tools far more complicated, and probably less useful than native tools already offered by these platforms.

In the meantime, I'll try to force the tool to "compile" on platforms other than Linux, but I'll mark things as unimplemented, so if anybody tries to actually use them, they would get a reasonable error.

[sylvestre]

sounds good, thanks!

[koutheir]

@sylvestre, I applied all your requests.
