Dependency resolution across provided AUR and repos

[ratijas]

Summary

Package from repository with exact match by name takes precedence and hides possible "provided" matches from AUR.

Description

Take a look at zsh/aura session in Konsole on a screenshot below.

Text from the session on a screenshot:

  "dotnet-host",

aura >>= Determining dependencies...

aura >>= The package dotnet-runtime-bin depends on version >=5.0.2 of dotnet-host, but the most recent version is 3.1.8.sdk108.

Command aura -A --json dotnet-host-bin | jq . shows a package details, and we can clearly see the "Provides" array. But aura refuses to even consider dotnet-host-bin as a candidate package to provide dotnet-host>=5.0.2, even though it was explicitly requested.

Expected behavior

Install all those specified packages at once. According to Arch Linux wiki on .NET Core they should be good together.

Actual behavior

Unable to resolve dependencies, hence refuses to install packages altogether.

Related

#683 seems like the same problem, but sideview. Might as well close a duplicate.

Version

aura-bin: 3.2.2-1

[fosskers]

It looks like current Aura is not considering "provides" correctly, at least when AUR packages are concerned. This might have been broken upon the last dependency solving logic rewrite.

That logic is being rewritten in the Rust port anyway, so let's wait for that and then use this specific issue here as a test case.

[ratijas]

Leads to interesting failures. Now I can't just upgrade all packages.
