Fix OS grain inconsistencies if lsb-release is installed or not #61626

bdrung · 2022-02-11T01:13:53Z

Most Linux distributions ship an os-release file by default. Some do not ship lsb-release information, but they can be installed afterwards. Installing/Removing lsb-release can lead to different OS grain values.

OS	grain	without lsb-release	with lsb-release
AlmaLinux 8	oscodename	AlmaLinux 8.5 (Arctic Sphynx)	ArcticSphynx
Astra CE	os	Astra (Orel)	AstraLinuxCE
Astra CE	os_family	Astra (Orel)	Debian
Astra CE	osfullname	Astra Linux (Orel)	AstraLinuxCE
Astra CE 2.12.40	osfinger	Astra Linux (Orel)-2	AstraLinuxCE-2
Debian	osfullname	Debian GNU/Linux	Debian
Mendel	osfullname	Mendel GNU/Linux	Mendel
Mendel 10	osfinger	Mendel GNU/Linux-10	Mendel-10
Mint	osfullname	Linux Mint	Linuxmint
Mint 20.3	osfinger	Linuxmint-20	Linux Mint-20
Pop	osfullname	Pop!_OS	Pop
Pop 20.04	osfinger	Pop!_OS-20	Pop-20
Rocky	osfullname	Rocky Linux	Rocky
Rocky 8	osfinger	Rocky Linux-8	Rocky-8
Rocky 8	oscodename	Rocky Linux 8.5 (Green Obsidian)	GreenObsidian

The current code that determines the OS grains on Linux is a mess: First lsb-release is queried. If that fails, fall back to read os-release and parse some /etc/*-release files. Then query _linux_distribution and use a mixtures of those for the OS grains. _linux_distribution queries the Python distro library. distro queries the os-release file, lsb-release, and then /etc/*-release.

Rewrite the code that determines the OS grains on Linux. Solely rely on the data provided by the os-release file. To not cause regressions, only switch the distribution that has been tested. All other distributions will use the legacy code (which was moved to _legacy_linux_distribution_data).

The new code derives the os_family grain from the ID_LIKE field from os-release (see #59061 for this feature request). To enable this feature, the new code needs to be used by default (and not just for selected distributions).

This commit introduces a few changes to the OS grains:

AlmaLinux and Rocky Linux extract the codename from the VERSION field now instead of using the full PRETTY_NAME.
Mendel uses now Mendel GNU/Linux as osfullname and correctly extracts the osrelease from PRETTY_NAME.
Pop!_OS changes the osfullname from Pop to Pop!_OS.
Astra Linux changes the osfullname from AstraLinuxCE to Astra Linux (Orel) and AstraLinuxSE to Astra Linux (Smolensk) respectively.

Fixes #61618

This merge request contains the commits from the merge request #61597, #61589, and #61619. So I recommend to review and merge those first.

Added the fix for Astra Linux.

@bdrung Can you resolve the conflicts for the two files and update.
Going through the changes etc., but need the conflicts resolved regardless.

Need to fix the Lint errors before reviewing
Update: And now the failing tests

bdrung · 2022-09-30T22:00:34Z

Some test cases fail due to #62220 (comment)

garethgreenaway · 2022-10-01T00:18:52Z

Lint errors are unrelated to this PR.

garethgreenaway · 2022-10-01T00:58:03Z

Looks good to merge once all the failing tests are resolved

The failing tests might be related.

@bdrung Just making sure you saw the failing tests on this PR and that they seem to be related to your changes. Thanks!

@bdrung Are you still interested in this PR ?, the 3 failing Debian tests need fixing.
