- Fedora 40+ ships dnf5 (not 41 as assumed) — pin to 39
- Debian container: /usr/bin/bash doesn't exist, use /usr/bin/dpkg
- Alpine: use busybox for LatestVersion test (always available)
- apk: Info test uses busybox (pre-installed) instead of curl (not installed)
- apk: LatestVersion test uses tree (installed during test)
- dpkg: Owner test uses /usr/bin/bash (not /bin/bash symlink)
- flatpak: List test checks both Name and Application ID fields
- dnf: pin Fedora to 41 (dnf4); dnf5 has incompatible output format
Type assertions require an interface type, not a concrete struct pointer.
Changed all integration tests from 'mgr := pkg.New()' to
'var mgr snack.Manager = pkg.New()' so capability checks like
mgr.(snack.VersionQuerier) compile correctly.
apt: VersionQuerier, Holder, Cleaner, FileOwner, RepoManager, KeyManager, NameNormalizer
dpkg: FileOwner, NameNormalizer
All new interfaces follow the existing pattern of exported methods on
struct delegating to unexported platform-specific functions. Mutating
operations use Lock/Unlock; read-only operations do not.
Platform stubs in _other.go files return ErrUnsupportedPlatform.
Compile-time interface checks added for all implemented interfaces.
- Add snack.Locker embed for per-provider mutex serialization
- Update all providers (pacman, apk, apt, dpkg) to use []Target
with version pinning support (pkg=version syntax)
- Add lock/unlock to all mutating operations (Install, Remove, Purge,
Upgrade, Update)
- Add snack.TargetNames helper and formatTargets per provider
- apt: add FromRepo (-t) and Reinstall support
- dpkg: use Target.Source for .deb file paths in Install
Implement the snack.Manager interface for both apt (Debian/Ubuntu) and
dpkg (low-level Debian package tool).
apt wraps apt-get, apt-cache, and dpkg-query for full package management.
dpkg wraps dpkg and dpkg-query for low-level .deb operations.
Upgrade and Update return ErrUnsupportedPlatform for dpkg.
Both packages include:
- Linux implementations with proper error wrapping
- Non-linux build stubs returning ErrUnsupportedPlatform
- Output parsing helpers with tests
- Functional options support (sudo, assume-yes, dry-run)
