Fix every finding surfaced by the canonical .golangci.yml with
golangci-lint v2.12.2 (refs #61), behavior-preserving throughout:
- err113: dynamic errors replaced with package-level sentinels and %w
wrapping; direct comparisons converted to errors.Is
- goprintffuncname: printf-style helpers renamed with an f suffix
(ui.Writer message methods, cli.ReportErrorf, database.Fatalf,
vaultik stdoutf) and all call sites updated
- revive: stuttering type names renamed (blob.Handler, blob.WithReader,
blob.ChunkPosition, storage.URL, storage.Info), doc comments added,
unused parameters blanked, package comments added
- contextcheck/noctx: ctx threaded through blob.Packer
(AddChunk/Flush/FinalizeBlob/PackChunks) and scanner call sites;
context-aware exec and sql variants used
- funlen/cyclop/gocognit/nestif/dupl: oversized or duplicated
functions split into focused helpers across production and test code
- paralleltest/tparallel/thelper/usetesting/testpackage: tests
parallelized where safe (global log.Initialize kept in the serial
phase), helpers marked, t.TempDir adopted, external test packages
where only exported API is used
- gosec: integer conversions clamped or justified, header timeouts
added, remaining findings suppressed with per-site justifications
- mnd/goconst/lll/wsl_v5/nlreturn/noinlineerr/errcheck and other
mechanical findings fixed directly
Remove the deprecated log.LogOptions alias (callers migrated to
log.Options). make check is green.
Adds regression tests for issue #28 (fixed in PR #33) to prevent
reintroduction of the double-close bug in CompressStream.
Tests cover:
- CompressStream with normal input
- CompressStream with large (512KB) input
- CompressStream with empty input
- CompressData close correctness
CompressStream had both a defer w.Close() and an explicit w.Close() call,
causing the compressor and encryptor to be closed twice. The second close
on the zstd encoder returns an error, and the age encryptor may write
duplicate finalization bytes, potentially corrupting the output stream.
Use a closed flag to prevent the deferred close from running after the
explicit close succeeds.
- Implement deterministic blob hashing using double SHA256 of uncompressed
plaintext data, enabling deduplication even after local DB is cleared
- Add Stat() check before blob upload to skip existing blobs in storage
- Add rclone storage backend for additional remote storage options
- Add 'vaultik database purge' command to erase local state DB
- Add 'vaultik remote check' command to verify remote connectivity
- Show configured snapshots in 'vaultik snapshot list' output
- Skip macOS resource fork files (._*) when listing remote snapshots
- Use multi-threaded zstd compression (CPUs - 2 threads)
- Add writer tests for double hashing behavior
- Add unified compression/encryption package in internal/blobgen
- Update DATAMODEL.md to reflect current schema implementation
- Refactor snapshot cleanup into well-named methods for clarity
- Add snapshot_id to uploads table to track new blobs per snapshot
- Fix blob count reporting for incremental backups
- Add DeleteOrphaned method to BlobChunkRepository
- Fix cleanup order to respect foreign key constraints
- Update tests to reflect schema changes
