Add dev-util/pkgcheck to SDK #2205

krnowak · 2024-08-06T15:53:46Z

It seems to be a useful tool, especially when trying to upstream things to Gentoo, as there is now a requirement to call pkgcheck on the changed packages.

CI: http://jenkins.infra.kinvolk.io:8080/job/container/job/sdk/1704/cldsv/

~~Blocked on #2193.~~

Changelog entries added in the respective changelog/ directory (user-facing change, bug fix, security fix, update)
Inspected CI output for image differences: /boot and /usr size, packages, list files for any missing binaries, kernel modules, config files, kernel modules, etc.

Before reviewing, I see there is a Docker image: https://github.com/pkgcore/pkgcheck/pkgs/container/pkgcheck did you try it? Something like:

$ podman run --rm -ti -w /opt -v "$PWD:/opt" ghcr.io/pkgcore/pkgcheck:sha-257d394
Python 3.12.3 (main, May 14 2024, 07:34:56) [GCC 12.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pkgcheck import scan
>>> for result in scan(['/opt']):
...     print(result)

You can also override the --entrypoint bash to get a bash interpreter and run the pkgcheck <scan> as usual

Ha, honestly, not really, I haven't tried using docker image. So not sure, I'm thinking that having it in SDK out-of-the-box still may be useful. It's something I could eventually add to the automation to check ebuilds in overlay.

You've changed some packages (pip, u-boot-tools, gflags, glog, tcl...) that aren't needed for pkgcheck, which makes this addition look heavier than it is.

I'm strongly in favour of adding this tool using packages rather than using Docker. It's part of my regular Gentoo workflow, and it's extremely good at catching QA issues. I feel like I'm flying blind without it. Using it with Flatcar from Gentoo itself is a bit of a pain because it's hardcoded to look at /etc/portage, which is pointing to the wrong repositories. I've had to make a wrapper to work around this.

#!/bin/bash

if [[ ${PWD} == ${HOME}/Projects/flatcar/scripts/sdk_container/src/third_party/* ]]; then
        exec bwrap --bind / / --bind ~/etc/portage/repos.conf /etc/portage/repos.conf --dev-bind /dev /dev /usr/bin/pkgcheck "${@}"
else
        exec /usr/bin/pkgcheck "${@}"
fi

Oh, I just need to rebase it. I think I based this branch on top of a branch that was adding dev-python/pip to automation, which resulted in bringing in a bunch of packages. Will do it on Monday.

Thanks for the hint. Talking about wrappers: do you think that having a wrapper inside SDK would be useful? I mean wrappers like pkgcheck-amd64-usr or pkgcheck-arm64-usr, that would use profiles from /build/{amd,arm}64-usr? Would there be something in pkgcheck that could take advantage of checking the ebuild against the generic profiles intead of SDK profiles being in /etc/portage?

Also, would pkgcheck maintainers be open to the idea of specifying a different config root? That way the bubblewrap-like wrappers wouldn't be necessary.

I don't think that's needed. Although pkgcheck seems to need a profile configured, it shows warnings across different profiles.

Also, would pkgcheck maintainers be open to the idea of specifying a different config root? That way the bubblewrap-like wrappers wouldn't be necessary.

It used to support that, but they dropped that support for some reason.

It certainly works for me outside the SDK. I'll give this a try.

krnowak · 2024-09-03T11:23:02Z

Just to be clear - that was me trying to run pkgcheck inside the SDK container.

krnowak · 2024-09-03T11:36:28Z

For the record, what I did was basically: git checkout main-4078.0.0-pkgcheck and then ./run_sdk_container -t -U. This gives yout eventually a bash prompt inside SDK.

chewi · 2024-09-03T12:51:35Z

Reproduced. I'll see if I can figure it out.

chewi · 2024-09-03T13:06:03Z

It works when make.profile points to a profile in portage-stable like /mnt/host/source/src/third_party/portage-stable/profiles/default/linux/amd64/23.0. Perhaps this is a pkgcheck bug where it doesn't like the profile being in an overlay.

chewi · 2024-09-03T13:09:51Z

Actually, it fails in a similar way when run against packages in coreos-overlay, regardless of the profile. I guess it just doesn't like something about coreos-overlay, but it works outside the SDK. 🤔

chewi · 2024-09-03T13:51:18Z

krnowak · 2024-09-04T12:47:29Z

Seems to be working now. It will spit a lot of warnings about nonsolvable or nondexistent deps for some packages though, because of our repos being a subset of Gentoo.

chewi · 2024-09-04T13:18:17Z

This might be a good idea:

/etc/pkgcheck/pkgcheck.conf

[DEFAULT]
keywords = -NonexistentDeps,-NonsolvableDepsInDev,-NonsolvableDepsInExp,-NonsolvableDepsInStable
