Summary

• use pacman -T to distinguish genuinely missing packages from requirements satisfied through Provides
• recover the installed provider version for status reporting
• skip provider-satisfied aliases during targeted upgrades so pacman does not attempt to replace the provider
• document the provider behavior

Root cause

pacman -Q resolves a requested capability to an installed provider but prints the provider's real package name. mise keyed that output by the printed name and then looked it up using the requested name, incorrectly classifying provider-satisfied requests as missing.

Fixes the behavior reported in #12181.

Validation

• cargo test --locked --bin mise system::packages::pacman
• mise run lint-fix

Note

Low Risk
Scoped to Linux pacman bootstrap logic with added tests; no auth or shared infrastructure changes, though upgrade filtering could skip upgrades users expected on alias names.

Overview
Fixes false "missing" package status when a configured Arch package name is satisfied by an installed provider via Provides (e.g. requesting mariadb-clients while percona-server-clients is installed).

Status checks now run pacman -T after pacman -Q for apparent misses, then re-query satisfied names to record the provider’s version (with version pins evaluated via deptest, including a bare-name deptest to separate mismatch from truly missing). upgrade only targets names that appear as directly installed in pacman -Q, skipping provider-only aliases and logging a warning so pacman does not try to replace the provider.

Docs for the pacman bootstrap backend describe provider-aware install detection and upgrade skipping. Unit tests cover provider query mapping and deptest parsing.

📝 Walkthrough

Walkthrough

Pacman package detection now evaluates version constraints through installed providers. Reusable query and parsing helpers classify package states and handle pacman results. Targeted upgrades skip provider-satisfied packages, with tests and documentation updated.

Changes

Pacman provider-aware package handling

Layer / File(s)	Summary
Pacman query and package-state helpers src/system/packages/pacman.rs	Adds reusable pacman -Q and pacman -T helpers, requirement formatting, output parsing, and centralized version-state classification.
Installed provider resolution src/system/packages/pacman.rs, docs/bootstrap/packages/pacman.md	The installed flow checks constrained dependencies, distinguishes provider version mismatches, applies provider versions, and tests these cases. Documentation describes provider-aware package checks.
Provider-aware upgrade filtering src/system/packages/pacman.rs, docs/bootstrap/packages/pacman.md	The upgrade flow skips packages satisfied by installed providers and exits when no targets remain. Documentation describes this behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 869c5

This change is localized to pacman provider handling, and no actionable merge-blocking risk remains after normal checks and review.

Poem

I’m a rabbit checking packages bright,
Providers satisfy names just right.
Constraints guide each hop and test,
Pacman marks the matching best.
Upgrades skip what is already found—
Tests and docs make paths sound.

Greptile Summary

The PR makes pacman package status checks provider-aware and avoids replacing installed providers during targeted upgrades.

• Uses pacman -T to distinguish missing requirements from installed virtual-package providers.
• Reports provider package versions for satisfied aliases.
• Filters provider aliases from targeted upgrades and documents the behavior.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains within the follow-up review scope.

Confirming this fixes the case from #12181, on a machine with percona-server-clients installed.

Built agent/fix-pacman-providers and ran it against a config declaring mariadb-clients, plus a package that genuinely doesn't exist:

pacman  mariadb-clients                9.7.1_1-1  installed
pacman  sqlite                         3.53.4-1   installed
pacman  definitely-not-a-real-package             missing

sudo pacman -S --noconfirm --needed -- definitely-not-a-real-package

On 2026.8.3 the first line reads missing and the install command includes it, which pacman then refuses — mariadb-clients and percona-server-clients both own /usr/bin/mysql.

I only exercised the unversioned path: no version pins, and I didn't test upgrade.
