Package checker for YunoHost

YunoHost project

Set of integration tests to check YunoHost packages. The package_check.sh script perform a series of tests on a package for verify its capability to be installed and removed in different situation. The test results are printed directly in the terminal and stored in the log file Test_results.log

Setup

Warning

We use LXD or Incus, which may conflict with other virtualization technologies. It may conflict with libvirt or LXC due to requiring dnsmasq on port 53. It will definitely conflict with Docker, but some workarounds are documented.

• install basic dependencies: sudo apt install lynx jq btrfs-progs
• install LXD or Incus
• make sure your user is in the lxd or incus-admin group (sudo usermod -a -G lxd MYUSER)
• restart your computer: this will ensure you have indeed the permissions, and that LXD/Incus can access the BTRFS kernel module
• make sure LXC/Incus is initialized with lxd init or incus admin init --minimal; in the case of LXD, make sure to use the btrfs storage driver unless you know what you are doing
• if using LXD, run this command to add the Yunohost image repository: lxc remote add yunohost https://repo.yunohost.org/incus --protocol simplestreams --public; at the time this README is written, fingerprint is d9ae6e76c374e3c58c3c20a881cffe7435809adb3b222ec393805f5bd01bb522

More details about LXD/Incus settings

If you'd like to use non-default settings with Incus, run `incus admin init` without the `--minimal` flag. In most cases, default settings are just fine, but be aware that the storage backend driver may have a large impact on performance.

Using the btrfs or zfs driver will provide best performance due to CoW, but it may not be available on all systems. In that case, the default storage may not be enough for your needs.

Additional steps if you have installed LXD with snap...

# Adding lxc/lxd to /usr/local/bin to make sure we can use them easily even
# with sudo for which the PATH is defined in /etc/sudoers and probably doesn't
# include /snap/bin
sudo ln -s /snap/bin/lxc /usr/local/bin/lxc
sudo ln -s /snap/bin/lxd /usr/local/bin/lxd

You can now setup and use package_check:

git clone https://github.com/YunoHost/package_check
cd package_check
./package_check.sh your_app_ynh

Features

The script is able to perform the following tests:

• Linter
• Install/remove/reinstall at the root of a domain (domain.tld/)
• Install/remove/reinstall in a subpath (domain.tld/foobar)
• Install/remove/reinstall with no url (for non-webapps)
• Install with is_public=0 (private install)
• Install multiple instances (if multi_instance is true)
• Upgrade from same version
• Upgrade from previous versions
• Backup/restore
• Changing the installation url (change_url)

Package_check script uses a LXC container to manipulate the package in a clean environment without any previous installations.

Usage: For a package in a directory: ./package_check.sh APP_ynh For a package on GitHub: ./package_check.sh https://github.com/YunoHost-Apps/APP_ynh

The app is expected to contain a tests.toml file (see below) to tell package_check what tests to run (though most of it is guessed automagically)

You can start a container on a different architecture with some hacks

Install the package qemu-user-static and binfmt-support, then list of all available images :

lxc image list images:debian/bullseye

Export the image of the architecture you want to run (for example armhf):

lxc image export images:debian/bullseye/armhf

This command will create two files.

• rootfs.squashfs
• lxd.tar.xz

We need to change the architecture of the metadata:

tar xJf lxd.tar.xz
sed -i '0,/architecture: armhf/s//architecture: amd64/' metadata.yaml
tar cJf lxd.tar.xz metadata.yaml templates

And reimport the image:

lxc image import lxd.tar.xz rootfs.squashfs --alias test-arm

You can now start an armhf image with:

lxc launch test-arm
lxc exec inspired-lamprey -- dpkg --print-architecture

If the build_base_lxc.sh script detects that you are trying a cross container architecture, it will try to perform this hack

tests.toml syntax

[default]

    # ------------
    # Tests to run
    # ------------

    # NB: the tests to run are automatically deduced by the CI script according to the
    # content of the app's manifest. The declarations below allow to customize which
    # tests are ran, possibly add special test suite to test special args, or
    # declare which commits to test upgrade from.
    #
    # You can also decide (though this is discouraged!) to ban/ignore some tests,

    exclude = ["install.private", "install.multi"]  # NB : you should NOT need this except if you really have a good reason ...

    # For special usecases, sometimes you need to setup other things on the machine
    # prior to installing the app (such as installing another app)
    # (Remove this key entirely if not needed)
    preinstall = """
    sudo yunohost app install foobar
    sudo yunohost user list
    """

    # -------------------------------
    # Default args to use for install
    # -------------------------------

    # By default, the CI will automagically fill the 'standard' args
    # such as domain, path, admin, is_public and password with relevant values
    # and also install args with a "default" provided in the manifest..
    # It should only make sense to declare custom args here for args with no default values

    args.language = "fr_FR"    # NB : you should NOT need those lines unless for custom questions with no obvious/default value
    args.multisite = 0

    test_upgrade_from.00a1a6e7.name = "Upgrade from 5.4"
    test_upgrade_from.00a1a6e7.args.foo = "bar"

    # On additional tests suites, you can decide to run only specific tests

    only = ["install.subdir"]

    args.language = "en_GB"
    args.multisite = 1

Note that you can run python3 lib/parse_tests_toml.py /path/to/your/app/ | jq to dump what tests will be run by package check

Test ids

The test IDs to be used in only/exclude statements are: install.root, install.subdir, install.nourl, install.multi, backup_restore, upgrade, upgrade.someCommitId change_url

Curl tests

Several curl tests can be defined under the [suite.curl_tests] block. Each curl test must have a unique ID to sort of "name" the test (for example home, home_logged_in, dash, admin, file, caldav, ...)

For each curl test, you may define the following properties:

• path: the app endpoint to test, relative to the defaults to /. Can be for example /foo/bar, /assets/logo.png, /api/whatever.json, ...
• logged_on_sso: true or false wether the test is performed being logged in on the SSO or not (default: false)
• expect_title: some text expected to be found in the HTML page's <title> (none/ignored by default)
• expect_content: some text expected to be found in the HTTP payload
• expect_return_code: integer, the expected HTTP return code (default 200)
• auto_test_assets: wether or not to test the first CSS and first JS asset found on the HTML page (default false except when the app provides no curl test and use the default mode)
• base_url: defaults to the app's install URL ($domain$path). Can be changed to something like https://__DOMAIN__ combined with path set to for example /.well-known/foobar, useful to test URLs which may be on a different domain or always at the domain root even when the app is on a subpath (such as well-known endpoints)

Using a btrfs storage pool

# Install btrfs tools
apt install btrfs-progs

# Create a partition. No need to format it!
fdisk /dev/sdb
# n for new then default values
# w to write and exit

# Remove the previous storage pool
incus profile device remove default root

# Create the storage pool (it will format and mount the partition)
incus storage create btrfs_pool btrfs source=/dev/sdb1

# Use it as the default pool
incus profile device add default root disk path=/ pool=btrfs_pool
