Complete rewrite of kappa from a sequential build tool into a
system-agnostic package manager with runtime init switching.
Core additions:
- 5 init system backends: systemd, openrc, s6, runit, dinit
(service file generation, enable/disable, init_paths)
- 2 bootloader backends: grub, limine (config generation, fallback entries)
- Parallel scheduler with worker pool, depth-based priority (Beta/Alpha/Zeta),
atomic claiming, dependency tracking, deduplication, and failure propagation
- Init-switch impact analysis: only rebuild packages using ${enabledinit}
- Init-agnostic service definitions: flat NamedService blocks replace
per-init nesting
- Package conflicts: mutual incompatibility detection in resolver
- System groups: init-agnostic group creation in DSL
- Init-agnostic hostname/timezone: direct /etc/hostname and /etc/localtime writes
- Source tarball caching at /kappa/cache/ with atomic write-then-rename
- Package recipe caching with remote fetching and version comparison
- remotes = [...] block in system config for package repositories
- Auto-fetch: rebuild resolves missing packages from remotes
- uninstall phase in package definitions
- ${enabledinit} eval variable for init-conditional builds
- Shared util module (to_lower, shell_escape)
- 54 integration tests across two shell test suites
- Comprehensive README and CONTRIBUTING guide
Bug fixes from review:
- CRITICAL: Replace std::system() with fork+execvp (command injection)
- CRITICAL: Fix scheduler deadlock on successful completion
- CRITICAL: Fix rebuild init/kernel/bootloader change detection
- HIGH: Fix path traversal via unsanitized package names in cache
- HIGH: Fix TOCTOU race in cache write with atomic rename
- HIGH: Fix formatter dropping remotes/imports blocks
- HIGH: Fix formatter stripping empty-string assert values
- HIGH: Fix formatter non-idempotent output (sorted key iteration)
- HIGH: Populate ${enabledinit} from boot.init in BuildStep
- MEDIUM: Fix data race on non-atomic scheduler stop flag
- MEDIUM: Fix compute_depths() traversal direction
- MEDIUM: Add runit to doctor supported-init warning
- MEDIUM: Extract to_lower/shell_escape to shared kappa::util
- MEDIUM: Consolidate generator declarations in headers
