Packages X and X-git are in conflict

[ratijas]

Summary

Aura does not consider provides section of AUR package during dependency resolution when an exact match exists in Arch repositories and custom version range is specified.

Description

Summary is based on my understanding of what happened. There were many things which might have gone south. It even may be considered an edge case.

• Package radare2-pipe-git^AUR depends on radare2>=${pkgver%.r*} which is 4.0.0.r0.ge258a53-1 in pipe's PKGBUILD.
• In turn, radare2 is provided by both community repo radare2 package and latest source build radare2-git^AUR.
• Version 5.0.0 had just dropped, so after installing from AUR, I have radare2 5.0.0.r25084.15d8de3819-1 locally, but its PKGBUILD was written for 4.6.0.r24570.3c88900134-1.

Somehow all those dots connect together in such a way that all AUR helpers suggest removing radare2-git in favor of radare2 binary package. Is it just a major versions conflict, or something bigger?

Expected behavior

Assume dependency radare2>=4.0.0.r0.ge258a53-1 installed because it is provided by radare2-git as radare-5.0.0.r25084.15d8de3819-1. Proceed with installation of radare2-pipe-git.

(by the way, why there's a blank line between "Determining dependencies..." and "Repository dependencies"?)

Thanks for the report. The dependency resolution algorithm will be getting a rewrite as I port to Rust.
