The ultimate way of testing ebuild contributions.

Summary: You keep a base container updated and in a tidy condition. You make copies of the base container, use the copies to test ebuild contributions, and delete the copies when you're done. This is automated as much as possible; in an ideal situation all you ever have to do, is give one command.

You can of course use this built environment to test your own ebuild modifications before pushing. Please see some examples how it works.

Pros Description
* safe (unprivileged) No root privileges or access required.
* fully isolated environment Play / test as much as you like, your live system won't break.
* runtime testing Not just build-test, but run GUI applications too.
* discardable snapshots (fast with binpkgs & SSD/NVME) No need to constantly run emerge --depclean in your test system.
* fast set-up for single-time use If you simply need a container for one-time testing, it's usable in less than 5 minutes. But there are better alternatives for that.
* use emerge against ::gentoo repository Using emerge is much better than using ebuild to test your work.
* OpenRC <-> systemd support Need to test systemd environment, but you use OpenRC? Don't worry, LXD is here for you.
* testing multiple PRs in parallel Launch as many build tests as you wish, and they won't interfere with each other.
* limit resources Apply per-container rules for maximum amount of CPU cores, RAM, or CPU usage.
* need a musl system? Or a clean environment to test -native-symlinks, clang, etc.
Cons Description
* this exact environment takes a while to set-up For continuous usage, it will live on for ages. At the time of writing, my base image has been going on for 10 months with little manual maintenance.
* I/O and storage heavy Truly negatable when using SSD/NVME.
* lots of automation can break Sometimes manual intervention is required, but rarely.
* prior knowledge of LXD It helps if you've used LXD before.
* prior knowledge of git It helps if you've used git before.

Installation

We're going to need LXD to be installed in the host system.

Important
I expect you to have LXD installed, and prior knowledge of using it. In this page, we are fast-tracking the required steps to get the environment going. If this is your first time installing LXD, please refer to its own wiki page. Especially setting up networking is vital for first-time setup.
root #emerge -av app-containers/lxd

You should expect to have at least 2-4 GB space per container, especially if they pull rust-bin, gentoo-kernel-bin etc. Therefore it might be wise to mount --bind /var/lib/lxd somewhere with more space available. Using an SSD/NVME is heavily suggested, as it makes all the operations happen in an instant compared to HDDs. Note that upstream suggests using mount --bind rather than symlinking a location, and you can obviously get the size down by making smart choices for pre-installed packages.

Configuring lxd

Add your user to newly created lxd group. chown your chosen lxd directory properly for this user.

We will use a binhost @ localhost to be used between host/container. Set up subuid & subgid for accessing binpkg repository from both in and outside the container.


Set up your container

Getting the correct container image

user $lxc remote add images https://images.linuxcontainers.org

Make sure to choose an image suited for your testing needs. Alternatively, create your own with Distrobuilder#Create_your_own_container_images.

user $lxc image list images: | grep gentoo
user $lxc launch images:gentoo my-test-container

This will download a default gentoo-x86_64 container image, set it up, name it as my-test-container and start it. You can check that it works,

user $lxc list
user $lxc exec my-test-container bash

But for now, we'll want to turn it off so we can configure it properly.

my-test-container #logout
user $lxc stop my-test-container

Edit the container config

default profile

You can edit the 'default' profile which, by default, gets used by containers and contain some necessary options.

user $lxc profile edit default

Note especially the network part. LXD#Setup_storage_and_networking

Container config

Accessing display from container to test GUI runtime

Edit the config file of your container.

user $lxc config edit my-test-container
config:
  environment.DISPLAY: :0.0
devices:
  X0:
    path: /tmp/.X11-unix
    source: /tmp/.X11-unix
    type: disk
  binpkgdir:
    path: /var/cache/binpkgs
    source: /home/joonas/sde1/binpkg
    type: disk
  distfiles:
    path: /var/cache/distfiles/
    source: /var/cache/distfiles/
    type: disk
  mygpu:
    type: gpu
profiles:
- default
Note
Check your DISPLAY information from e.g. xrandr or echo $DISPLAY.
Note
Sometimes it's still required to call xhost +local: or xhost + from host.


Sharing host's disk to container

With the example above, we're sharing our host's distfiles and binpkg directories with the containers.

Note
source: is the one in your host system, path: is how it shows up in container.
Note
You can share your ::gentoo repository between host and container, but it's for advanced users only. It enables you to easily test your own commits before pushing them, though, with the script shown below.
Important
Make sure your user is in portage group if you want to share your distfiles location between all containers and host!


Launching the container

Now that we've configured the relevant parts, we can launch the container. We'll construct the base container image that is kept up-to-date and clean. We'll use that to create discardable copies, where the testing happens.

user $lxc start my-test-container
user $lxc exec my-test-container bash

Initiate configuration

First thing, we need to get a portage tree.

my-test-container #emerge-webrsync

Or alternatively, wget the latest portage tree from any of the mirror's /snapshots/portage-latest.tar.xz and extract it as /var/db/repos/gentoo.

Install dev-vcs/git and an editor of your choice:

my-test-container #emerge -av dev-vcs/git app-editors/emacs app-editors/vim

Now we need to initiate the git-repo, and /etc/portage/ configuration for our container. There are two ways for it:

Automatic configuration via a script

A fast and simple way is to use this script:

my-test-container #cd /root
my-test-container #chmod +x initialize_my-test-container.sh
my-test-container #./initialize_my-test-container.sh
Important
Always read through random scripts you wget from the Internet before running them!
Important
You will need to edit your custom /etc/portage/make.conf.custom file which gets sourced by make.conf. See example here.

When done, skip straight to updating your container.

Alternatively, manual configuration

Prepare the usage of git sync-repo.

my-test-container #cd /etc/portage
my-test-container #mkdir repos.conf
my-test-container #edit /etc/portage/repos.conf/gentoo.conf
FILE /etc/portage/repos.conf/gentoo.confContainer
[DEFAULT]
main-repo = gentoo

[gentoo]
location = /var/db/repos/gentoo
sync-type = git
sync-uri = https://anongit.gentoo.org/git/repo/sync/gentoo.git
auto-sync = true
sync-depth=1
Important
Make sure you're using a sync-friendly repo with metadata cache available!
Note
Using https://github.com/gentoo-mirror/gentoo is fine too, if it provides faster speeds for you.
my-test-container #rm -rf /var/db/repos/gentoo/*
my-test-container #emerge --sync
my-test-container #eselect news read

Edit relevant /etc/portage files.

my-test-container #cd /etc/portage
my-test-container #mkdir -p env package.accept_keywords package.env package.unmask package.use /var/tmp/portage/vbslogs

Edit all the relevant files you need to. make.conf, make.conf.custom, package.use/default, package.accept_keywords/default, package.mask/default, env/test.conf etc.

Always find the latest container /etc/portage config files from https://github.com/juippis/my-gentoo-lxd-scripts/tree/master/container/etc/portage and use wget to get them.

If you wish to git pull only the shell scripts used in testing pull requests, and not /etc/portage files, follow these steps:

my-test-container #cd /root
my-test-container #git clone --depth=1 https://github.com/juippis/my-gentoo-lxd-scripts.git --no-checkout lxd-bin
my-test-container #cd lxd-bin/
my-test-container #git config core.sparsecheckout true
my-test-container #echo container/bin/* > .git/info/sparse-checkout
my-test-container #git read-tree -m -u HEAD
my-test-container #echo "PATH=\"\$PATH:~/lxd-bin/container/bin\"" >> /root/.bashrc
my-test-container #cp /root/.bashrc /root/.profile

Binhost / binpkgs

With the above settings we are enabling binpkgs to be generated, and used, for everything other except packages we're actually testing. This will speed up testing process immensively. Make sure your user has correct permissions in your host to be able to write to shared binpkg directory.


Update your container

Note
If you intend to use your container for stable arch testing, obviously re-define some variables in the make.conf.custom file, such as KEYWORDS. Otherwise, grab a coffee, sit back and relax.
Important
Make sure you've correctly handled your /etc/portage directory, i.e., you have make.conf and make.conf.custom set up. An example make.conf.custom
Important
Please read https://ahelpme.com/linux/tmpfs-mount-on-dev-shm-in-lxc-container-or-chroot-environment/ first, if you're using OpenRC in host system. A fast fix is to
my-test-container #mkdir -p /dev/shm
my-test-container #mount -t tmpfs -o nodev,nosuid,noexec,mode=1777,size=6144m tmpfs /dev/shm

before trying to update @world. Note that this needs to be done everytime the container is started. You can put those commands in ~/.bashrc and ~/.profile inside your container, or use lxc.raw.config.

https://github.com/juippis/my-gentoo-lxd-scripts/tree/master/container/bin repo ships a script, /root/lxd-bin/container/bin/fixshm.sh that you can call. The initialize_my-test-container.sh executes it automatically for you.
Important
To suppress some noise during update, you can
my-test-container #emerge -av app-portage/iwdevtools
already at this point. Or you can un-symlink /etc/portage/bashrc for the time being.

Start the update. Remember to switch profiles here if you need to.

my-test-container #emerge -uavDN @world
my-test-container #perl-cleaner --all
my-test-container #eselect news read
my-test-container #etc-update
Important
Be careful when updating /etc/inittab in container not to lose pf:12345:powerwait:/sbin/halt - it will cause container management issues.

Let's use the latest gcc.

my-test-container #gcc-config -l
my-test-container #gcc-config 2
my-test-container #source /etc/profile
Note
You can logout and login to your container for changes to take effect.

Install necessary tools

my-test-container #emerge -av app-admin/eclean-kernel app-editors/emacs app-emacs/ebuild-mode app-editors/vim app-portage/gentoolkit app-portage/pfl app-portage/portage-utils dev-util/pkgdev app-text/ansifilter dev-util/pkgcheck sys-kernel/gentoo-kernel-bin x11-base/xorg-server app-portage/pkg-testing-tools app-portage/iwdevtools net-misc/dhcp
Note
Obviously, edit to your needs. The base image can be a lot smaller depending on your choices here, but testing-time will increase for ANY GUI application. xorg-server does pull llvm though.

We use pfl to help keep https://www.portagefilelist.de/ relevant since we are installing tons of different packages over time.

pkgdev, pkgcheck, gentoolkit and portage-utils are installed so we can edit and fix any .ebuild files we are testing.

ansifilter is for cleaner logs. Although it may bug sometimes, be aware of that.

gentoo-kernel-bin ensures we won't run into problems when emerging packages that do kernel modules. They are rare. You can easily share your hosts /usr/src/ and /lib/modules/ if you know you'll never run into these packages, as the container itself uses hosts running kernel. You won't have write access from inside the container to these directories on host, so the ebuilds will fail peacefully.

pkg-testing-tools the tool all of our testing leans onto, and our scripts depend upon.

iwdevtools are a set of scripts that enable many different QA checks to our testing. By default they're enabled with my settings.

net-misc/dhcp just a suggestion for any network connectivity tool. OpenRC by default uses netifrc, which may require more configuring to work out-of-the-box, and config_eth0="dhcp" is specified.

Container-specific modifications to pkg-testing-tools

This step is optional.

Our testing depends heavily on https://github.com/slashbeast/pkg-testing-tools. To "configure" it for specific cases, we'll have to patch it directly utilizing /etc/portage/patches/.

Get the container-specific patches from here: https://github.com/juippis/my-gentoo-lxd-scripts/tree/master/pkg-testing-tool-patches

For example for general pull request testing, against =app-portage/pkg-testing-tools-0.1.0, we'd do:

my-test-container #mkdir -p /etc/portage/patches/app-portage/pkg-testing-tools-0.1.0/
my-test-container #wget https://raw.githubusercontent.com/juippis/my-gentoo-lxd-scripts/master/pkg-testing-tool-patches/mtc/0.1.0/disable-systemd-enable-flags.patch -O /etc/portage/patches/app-portage/pkg-testing-tools-0.1.0/disable-systemd-enable-flags.patch
my-test-container #emerge -av app-portage/pkg-testing-tools --usepkg=n
Note
Depending on your use case, you might want to enable autounmasking. For KEYWORD Arch Testing work, don't do it. For general ebuild testing in ~unstable system, it might be a good idea.
Note
Be aware that currently pkg-testing-tool isn't very good at doing PYTHON_SINGLE_TARGET and LUA_SINGLE_TARGET testing, so you might want to add such test cases manually into "export USE". See https://github.com/slashbeast/pkg-testing-tools/issues/9 to track status of this bug.

Set up container scripts

If you've followed the steps above, your container should have /root/lxd-bin/container/bin/ directory with contents from https://github.com/juippis/my-gentoo-lxd-scripts/tree/master/container/bin - if you didn't use initialize_my-test-container.sh add this $PATH to your container's /root/.bashrc and /root/.profile:

FILE /root/.bashrc & /root/.profileContainer
PATH="$PATH:~/lxd-bin/container/bin"
/root/lxd-bin/container/bin/fixshm.sh

Finishing touches for your container

We'll do a world update and depclean remnants after editing our /etc/portage. Then run pfl to submit the initial list, and from now on running pfl from a snapshot-container or main container will only submit modified package list when comparing to base image.

my-test-container #emerge --update --newuse --deep @world
my-test-container #emerge -a --depclean --with-bdeps=n
my-test-container #pfl

Log out, turn off container.

my-test-container #logout

(Ctrl+d works too)

user $lxc stop my-test-container

Set up host scripts

Automatic way via git sync

user $mkdir -p ~/bin/lxd-host-scripts
user $cd ~/bin/lxd-host-scripts
user $git clone --depth=1 https://github.com/juippis/my-gentoo-lxd-scripts.git --no-checkout lxd-host-bin
user $cd lxd-host-bin/
user $git config core.sparsecheckout true
user $echo host/bin/* > .git/info/sparse-checkout
user $git read-tree -m -u HEAD
user $echo "PATH=\"\$PATH:~/bin/lxd-host-scripts/lxd-host-bin/host/bin\"" >> ~/.bashrc
user $cp /root/.bashrc /root/.profile

You should now have the contents of https://github.com/juippis/my-gentoo-lxd-scripts/tree/master/host/bin in your host's user dir ~/bin/lxd-host-scripts/lxd-host-bin/host/bin. git pull occassionally to get updates.

Relog or invoke bash to get $PATH updated.

Manually by wgetting

Just take a look at https://github.com/juippis/my-gentoo-lxd-scripts/tree/master/host/bin and wget / copy-paste manually to your host user's bin dir. Add the script dir to your $PATH via ~/.bashrc and/or ~/.profile, relog or invoke bash to get $PATH updated.


Cron job to keep container up-to-date automatically

Use your desired cron system to make the host's maintenance script a cron job. In other words, ~/bin/lxd-host-scripts/lxd-host-bin/host/bin/container_maintain_my-test-container.sh can be ran to keep the base image updated.


Individual scripts explained

Host

container_maintain_my-test-container.sh

Script that attempts to gather all container's base maintenance tasks. Can be cron'd or called manually before each "test session".

container_start_my-test-container.sh

Simple helper script to do manual tasks in the base container. Rarely used.

container_start_tmptestmycontainer.sh

Sets up a generic testing environment fast. You can use this for personal stuff.

test-pr.sh

Gets a Github pull request as a parameter, and sets up a new environment to test it. Attempts to include every necessary step to confirm that the PR builds.

Container

disable-native-symlinks.sh

Quick and dirty script to disable native-symlinks. Ideally this gets called via test-pr.sh -n 12345.

errors_and_qa_notices.sh

Just an error grepper. Spams the screen for any pre-defined checks.

fixshm.sh

Required for some openrc systems to populate devices inside container.

fullget.sh

Gets the Github pull request and applies it onto ::gentoo tree. In future, any git-format patch should be appliable.

initialize_my-test-container.sh

Designed to be ran one-time only whenever a new container is launched. Makes boring tasks easier.

prtester.sh

Identifies .ebuild files that have changed against git-tree's HEAD state, and proceeds to test them.

rdeptester.sh

Give package as a parameter and it tests reverse dependencies of given package. By default it picks 6 rdeps, but with an -a flag it tests them all. Good for checking library updates which don't have test phase enabled.


Testing that everything works!

Choose any PR to your liking from https://github.com/gentoo/gentoo/pulls. Do note that it can't be CLOSED, in other words, merged to main tree as that will cause patch merging collision. And it should edit an .ebuild file, ideally adding a new .ebuild to the tree to be tested.

user $test-pr.sh 12345

You can always, at any given time log in to the container and inspect / test everything manually. This is especially handy if you spot a mistake in the .ebuild file and need to test that your modification works.

user $lxc list
user $lxc start my-test-container-snap-12345
user $lxc exec my-test-container-snap-12345 bash

Acknowledgements / TODO

  • The scripts are most likely awful, but after I've gotten them to work, I haven't looked back. https://imgs.xkcd.com/comics/is_it_worth_the_time.png
  • The prtester.sh itself can be used to build a tinderbox checking all commits, but an automated bug-reporting system would be needed then. However, it might be good for overlays. You'll need to store the git checkout of a previous run, then compare that to ..HEAD.
  • test-pr.sh could run emerge --sync before applying patches, but it's not needed for my own workflow since I usually do all testing once a day.
  • I need better error handling with errors_and_qa_notices.sh. Take example list from https://github.com/toralf/tinderbox/blob/master/data/CATCH_QA and work with that. Also the rundown could use enhancements.
  • I'm making this public to hear feedback! Ideally I'd want an infra-hosted service with Github hook that tests PRs on-demand. After a Gentoo developer has reviewed the PR, they could launch a build-test from Github, which would then return PASS or FAIL to the PR with web-browsable logs.
  • TODO: Study possibility to use SquashFS to reduce container image sizes.
  • TODO: Switch to tatt instead, with custom scripts?
  • (TODO in Github)
