bump nix to 0.29.0

[kemingy]

Description

Hi. This is a version bump for nix.

The main reason is that I'm looking for a rust cgroups crate, the libcgroups could be the best one I can find that works and has been maintained well.

However, the interface requires fn add_task(&self, pid: Pid) bind to nix 0.28, which could be tricky to work with if users use other versions.

So, I guess we can bump the version now. Later, maybe we could adjust the interface to make it more convenient for general purposes.

Hye @kemingy Thanks for the PR. overall looks good to me as no major code changes ; so should be good to merge if all CI passes. Strange that dependabot did not notify us for this. I guess I closed a PR for nix few versions ago due to breaking changes in nix, and dependabot must be ignoring all minor version updates due to that ; will need to see how we can fix it.

As you have mentioned that this is to be used in a project (seems pretty cool!) I would like to clarify that I'm not sure when we will do another release for this. I have a couple of bug fixes + Rust edition upgrade that I want to merge, maybe another couple of stuff that some other people would like to get merge before we would do a release ; so if you are fine to pin the version by SHA, you can do so after we merge the PR, else you can subscribe to the tagpr PR #3124 to see when we do the release.

Thanks for your contribution :)

Hi @YJDoc2 thanks for the information. I'm okay to pin the SHA before the next release.

lgtm. Thanks for your contribution :)

Hi @YJDoc2, it seems the dependabot still ignores nix. Can you check:

• @dependabot show <dependency name> ignore conditions
• @dependabot unignore <dependency name>

I guess those commands require the maintainer's permission to run.

[YJDoc2]

@dependabot show nix ignore conditions

@dependabot show nix ignore conditions

Hi @YJDoc2, I tried and found that this command only works in the PR created by the dependabot. (closed PR also works)
