with '--sysupgrade' option paru doesn't respect (doesn't send to pacman) specified target version

[andrei-korshikov]

Affected Version

paru v2.0.1 - libalpm v13.0.2

Description

If there are two repositories with different versions of the same package, pacman by default installs the latest version of the package package from the first repo listed in pacman.conf (man pacman.conf: "repositories listed first will take precedence over those listed later in the file when packages in two repositories have identical names, regardless of version number"), but it is possible to specify the needed (old) version. With --sysupgrade option paru doesn't support this and always tries to install the latest version package from the first repo from pacman.conf .

Background information:
I use ZFS, so using something like sudo pacman --sync --sysupgrade --refresh linux{,-headers}=6.7.4.arch1-1 linux-lts{,-headers}=6.6.16-1 linux-zen{,-headers}=6.7.4.zen1-1 is very common workflow for me. ZFS packages are usually slightly behind the latest kernels, and each zfs package requires its very specific corresponding kernel.

Here is blog post with detailed description of the use case.

Output

Intended behavior (simulated with pacman):

sudo pacman --sync --sysupgrade --refresh  linux{,-headers}=6.7.4.arch1-1  linux-lts{,-headers}=6.6.16-1  linux-zen{,-headers}=6.7.4.zen1-1

Paru with --sysupgrade (bad behavior):

paru --sync --refresh --sysupgrade linux{,-headers}=6.7.4.arch1-1  linux-lts{,-headers}=6.6.16-1  linux-zen{,-headers}=6.7.4.zen1-1

Paru without --sysupgrade (expected behavior):
