Generates a ~1MB manifest (20000 files with random names), then:
- Verifies truncated manifest causes check to fail
- Runs 500 iterations of random single-byte corruption
- Each iteration verifies check detects the corruption
- Atomic writes for mfer gen: writes to temp file, renames on success,
cleans up temp on error/interrupt. Prevents empty manifests on Ctrl-C.
- Humanized byte sizes using dustin/go-humanize (e.g., "10 MiB" not "10485760")
- Progress lines clear when done (using ANSI escape \r\033[K])
- Debug logging when files are added to manifest (mfer gen -vv)
- Move -v/-q flags from global to per-command for better UX
- Add tests for atomic write behavior with failing filesystem mock
- Version command now uses mfer.Version constant instead of empty build flags
- Running just 'mfer' shows banner + help
- Unknown commands still return error with exit code 1
- pathIsHidden(".") was returning true, causing freshen to skip entire
directory tree when dotfiles excluded
- Banner now prints directly to stdout to avoid log prefix artifacts
Changed the default behavior to exclude dotfiles (files/dirs starting with .)
which is the more common use case. Added --include-dotfiles flag for when
hidden files need to be included in the manifest.
Major changes:
- Refactor CLI to accept injected I/O streams and filesystem (afero.Fs)
for testing without touching the real filesystem
- Add RunOptions struct and RunWithOptions() for configurable CLI execution
- Add internal/scanner package with two-phase manifest generation:
- Phase 1 (Enumeration): walk directories, collect metadata
- Phase 2 (Scan): read contents, compute hashes, write manifest
- Add internal/checker package for manifest verification with progress
reporting and channel-based result streaming
- Add mfer/builder.go for incremental manifest construction
- Add --no-extra-files flag to check command to detect files not in manifest
- Add timing summaries showing file count, size, elapsed time, and throughput
- Add comprehensive tests using afero.MemMapFs (no real filesystem access)
- Add contrib/usage.sh integration test script
- Fix banner ASCII art alignment (consistent spacing)
- Fix verbosity levels so summaries display at default log level
- Update internal/log to support configurable output writers
