- 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.
Pass 2 (Correctness & Safety):
- Separate stdout/stderr in apk list and search to prevent error messages
from contaminating parsed output
- All providers verified: mutex on mutating ops, CommandContext everywhere,
proper error wrapping, nil-safe parseInfo functions
pacman:
- VersionQuerier: latestVersion via pacman -Si, listUpgrades via pacman -Qu,
upgradeAvailable via pacman -Qu <pkg>, versionCmp via vercmp
- Cleaner: autoremove via pacman -Qdtq | pacman -Rns, clean via pacman -Sc
- FileOwner: fileList via pacman -Ql, owner via pacman -Qo
- Grouper: groupList/groupInfo via pacman -Sg, groupInstall via pacman -S
- Note: Holder skipped (no clean CLI support)
apk:
- VersionQuerier: latestVersion via apk policy, listUpgrades via apk upgrade --simulate,
upgradeAvailable by checking upgrade list, versionCmp via apk version -t
- Cleaner: clean via apk cache clean, autoremove is no-op (not supported)
- FileOwner: fileList via apk info -L, owner via apk info --who-owns
- 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
Implements the snack.Manager interface for Alpine Linux's apk-tools:
- Install, Remove, Purge, Upgrade, Update operations
- List installed, Search, Info, IsInstalled, Version queries
- Output parsing for apk list, search, and info formats
- Linux-only implementation with build-tag stubs for other platforms
- Options support: WithSudo, WithDryRun, WithRoot
- Tests for all output parsing functions
