Here is a test, maybe you can take a look and try enabling it for musl as well:) |

I expanded the scope of this PR a bit and enable the tests. Thought I still wonder why Linux/musl/aarch64 wasn't enabled in the initial implementation in #2044 |
The tests seem to be passing 🤔 |
I think it is because the author's use case does not target

LGTM, thanks for the patch!
Awesome, thanks for the merge! When should we expect a new release? 😇 |
Probably not soon, the I/O safety port is still not done, even though we finish it quickly, we still need to test it. Can you guys use a git dependency, though this would stop you from releasing to crates.io, I am not sure if this will block lurk from being included in Alpine Linux |
Thanks for letting me know!
Yeah, weekly alpha/rc releases would be really useful for these cases. Both for accessing the versions quickly and testing it :)
I'm not sure as well, just asked them 👀 |

We forgot to enable the RegisterSet
trait and enum RegisterSetValue
for linux/aarch64/musl
in this PR, I found this while reviewing #2507, the CI does not catch it as well because we don't have CI for this triple:<

I added support for aarch64-unknown-linux-musl for getregs() function and it builds fine now, but I don't have a way to test it.
I am kinda surprised that Rust does not catch this at compile time. 🤔
@orhun, could you please give this a fix and if possible, give this a try with lurk?

I try to fix this issue and add the CI for aarch64/musl
in #2510, but it looks like the constants needed by enum RegisterSetValue
have not been defined in the libc crate, so we need to add them there first.

Ah damn, good catch, these arch stuff goes deep!
Do you want me to test it out with lurk? Is there any other thing that I can help here?

Exactly 😪
Do you want me to test it out with lurk?
Yeah, that would be great! Once #2510 is merged, we can start the test:)
Is there any other thing that I can help here?
Currently, no, I may ping you when I do need you 😁
What does this PR do
I needed this specific API for packaging my project for Alpine Linux distribution:
I added support for
aarch64-unknown-linux-musl
forgetregs()
function and it builds fine now, but I don't have a way to test it.Also, I'm not sure if this is the correct way to add support for this architecture - but should be fine!
Let me know what you think and I can try adding support for other functions (such as
setregs()
) as well.BTW this is my first PR to the
nix
crate so please let me know if I'm doing something wrong 🐻Checklist:
