User:Juippis/The ultimate testing system with lxd

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.

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

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 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. 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.

Getting the correct container image
Make sure to choose an image suited for your testing needs.

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,

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

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

Note especially the network part. LXD

Accessing display from container to test GUI runtime
Edit the config file of your container.

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

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.

Initiate configuration
First thing, we need to get a portage tree.

Or alternatively, the latest portage tree from any of the mirror's  and extract it as.

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

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:

When done, skip straight to updating your container.

Alternatively, manual configuration
Prepare the usage of git sync-repo.

Edit relevant files.

Edit all the relevant files you need to. ,, , , , etc.

Always find the latest container 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 only the shell scripts used in testing pull requests, and not  files, follow these steps:

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

Let's use the latest gcc.

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.

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:

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

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

Log out, turn off container.

(Ctrl+d works too)

Automatic way via git sync
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. occassionally to get updates.

Relog or invoke 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 and/or, relog or invoke  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, can be ran to keep the base image updated.

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.

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

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.

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.

Examples
A couple of real-life examples with full output below.

'''Example 1: Simple PR with no deps. Gets ran with  and  .'''

All looks good. Proceed to merge using pram (or if you share your ::gentoo repository between container/host, just do.

Example 2: PR bumping a package with some USE flags, and a test phase available.

All looks good. Proceed to merge using pram (or if you share your ::gentoo repository between container/host, just do.

Example 3: A PR with multiple commits touching different packages:

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  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.
 * could run  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 . 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)
