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.
- Implement exclude patterns with anchored pattern support:
- Patterns starting with / only match from root of source dir
- Unanchored patterns match anywhere in path
- Support for glob patterns (*.log, .*, **/*.pack)
- Directory patterns skip entire subtrees
- Add gobwas/glob dependency for pattern matching
- Add 16 comprehensive tests for exclude functionality
- Add snapshot prune command to clean orphaned data:
- Removes incomplete snapshots from database
- Cleans orphaned files, chunks, and blobs
- Runs automatically at backup start for consistency
- Add snapshot remove command for deleting snapshots
- Add VAULTIK_AGE_SECRET_KEY environment variable support
- Fix duplicate fx module provider in restore command
- Change snapshot ID format to hostname_YYYY-MM-DDTHH:MM:SSZ
