fix(v2): detect versioned webkit2gtk package on Arch - #6024
Conversation
Arch split webkit2gtk into versioned packages and dropped the unversioned one from the repositories, so `pacman -Si webkit2gtk` now fails even on a system with WebKit properly installed: $ pacman -Q webkit2gtk-4.1 webkit2gtk-4.1 2.52.3-1 $ pacman -Si webkit2gtk error: package 'webkit2gtk' was not found The pacman package map only knew the old name, so PackageAvailable() returned false and `wails doctor` bailed out with "Fatal: Required dependencies missing: libwebkit" on a machine that builds fine. Dependencies() already treats the []*Package slice as ordered alternatives and stops at the first available candidate, so adding webkit2gtk-4.1 as a second candidate is enough. The unversioned name stays first so a system that still has 4.0 keeps reporting the package a default build links against. This brings pacman in line with the rest of the tree rather than breaking new ground: xbps.go already lists libwebkit2gtk41-devel as Void's only libwebkit candidate, so v2 doctor has been accepting a 4.1-only system on another distro for some time, and the v3 doctor's pacman map lists webkit2gtk-4.1 too. Also update the Arch note in the Linux distro support guide, which still claims both packages are available. Fixes wailsapp#5775.

Arch only ships webkit2gtk-4.1 now, so the ABI 4.0 example was pointing at a package that no longer exists.
|
Good catch, dropped the Arch override from the ABI 4.0 example too. |
|
I think it'd be worth showing that tag requirement... I'm wondering how we could keep it consistent though. |
|
Added it. Package entries can now carry the build tags they need (a BuildTags field), and doctor prints a note for whatever WebKit package it resolved to when that's set, so it works the same on every distro that lists a 4.1 package, currently Arch and Void. I left the task-file / wails3 setup side alone for now; happy to look at that separately if you want it. |
…gs webkit2_41 Package entries can now carry the build tags a project needs to use them, and doctor prints a note for any resolved dependency that has some. The 4.1 ABI entries on pacman and xbps set webkit2_41, so a system that doctor reports as ready no longer fails a plain wails build without explanation.

- Around line 38-39: Update the dependency alternative selection in Pacman
Dependencies to prefer an installed WebKit package before considering repository
availability, so webkit2gtk-4.1 is selected when installed even if webkit2gtk is
listed first; retain the first available alternative as the fallback and
preserve its BuildTags. Add coverage for both alternatives being available with
only webkit2gtk-4.1 installed.

Dependencies stopped at the first alternative the repo offered, so on Manjaro, which still ships both webkit2gtk and webkit2gtk-4.1, a system with only 4.1 installed was reported as needing webkit2gtk and lost the webkit2_41 build tag note. Keep scanning for an installed alternative and only fall back to the first available one when nothing is installed.

Good catch. Dependencies now keeps scanning for an installed alternative and only falls back to the first available one when nothing is installed, so a Manjaro box with just webkit2gtk-4.1 is reported as installed with the webkit2_41 note. Added a small table test with a fake package manager covering the both-available case. |
