v0.2.0 -- Ground Truth

Ground Truth

This release prioritizes honesty over feature claims. Commands either work or tell you they can't.

Breaking Changes

• mocker create, rename, pause, unpause now return explicit unsupported errors instead of silently mutating local metadata
• mocker login / logout now return unsupported error (credentials were never consumed by pull/push)
• Unsupported flags in mocker run now produce stderr warnings

Security Fixes

• Fix shell injection in copyToContainer -- replaced sh -c with stdin pipe to tee
• Fix shell injection in compose hostname injection -- same pattern
• Fix pipe-buffer deadlock in both paths (async terminationHandler instead of blocking waitUntilExit)

Flag Forwarding

• Forward Apple CLI flags in mocker run: -i, -t, -c, -m, --label, --cidfile, --rm, --tmpfs, --dns-search, --dns-option, --platform
• Forward Apple CLI flags in mocker build: --label, --quiet, --progress, --output
• Fix hostname parser (use assigned name, not inspect hostname field)

Documentation

• 12 commands marked [unsupported] in COMMANDS.md
• Compatibility notes added to both READMEs
• Feature claims qualified ("Docker CLI compatible" not "full compatibility")

Testing

• ProcessRunner protocol + MockProcessRunner actor for testability
• 16 new tests (42 total, was 26)
• ContainerEngine, ComposeOrchestrator, and flag enforcement tests

Other

• All version strings unified via Version.currentVersion
• Volume list prunes stale entries where _data/ directory no longer exists

v0.1.6

fix: resolve named volumes to host paths for compose

Apple's container CLI does not support named volumes (-v name:/path).
Convert named volumes to their host mountpoint directories so bind mounts
are used instead (e.g. pgdata -> ~/.mocker/volumes/project-pgdata/_data).

v0.1.5

fix: resolve relative build context paths against CWD

URL(fileURLWithPath:).standardized does not resolve relative paths
like ../crw-opencore. Explicitly resolve against the current working
directory so build contexts like 'build: ../service' work correctly
in docker-compose.yml.

v0.1.4

fix: always pass -f flag to container build to use correct Dockerfile

container build defaults to CWD/Dockerfile, not context-dir/Dockerfile.
When compose build context is in a different directory (e.g. ../crw-opencore),
the wrong Dockerfile was being used. Now always pass -f with the resolved
absolute path to the Dockerfile in the build context directory.

v0.1.3

fix: add compose kill subcommand and --timeout flag to compose down

- Add `mocker compose kill [service]` to force-stop containers
- Add `--timeout <seconds>` option to compose down (default: 10)
- Fixes compatibility with dev.sh which uses both features

v0.1.2

fix: compose up accepts service names, compose down accepts --remove-…
