With --continue, check stopped at the first file whose content or
checksum attribute it could not read, and at the first directory it
could not list. Each of these now counts as failed, its error, which
names the path, goes to stderr, and the walk goes on; the run still
exits non-zero. The walk shared with sum and clear takes the continue
setting, and they pass false. If the count that sizes the progress bar
cannot read a path, check --continue runs without the bar. Without
--continue the first such error still stops the run, and the summary
printed before it now counts an unreadable checksum attribute as
failed, as it already did for unreadable content.
Model: opus-5-5
Fix every golangci-lint finding under the repo's standard .golangci.yml
(from ~192 down to 0 under the pinned v2.10.1) without changing program
behavior:
- gochecknoglobals: replace the verbose/quiet/exclude* package globals with
an options struct threaded through the command implementations.
- err113: introduce package-level sentinel errors and wrap them with %w.
- errcheck: check or explicitly discard every previously unchecked error
(bar.Add/Finish, deferred Close, verbose writes).
- forbidigo: route verbose output through os.Stdout instead of fmt.Print*.
- noinlineerr / wsl_v5 / nlreturn / gofmt: split inline error checks and
normalize whitespace.
- complexity (cyclop/gocognit/nestif): extract small behavior-preserving
helpers (runOverPaths, countAndBar, walkSkip, clearOne, checkOne,
missingChecksum, reportCheck).
- mnd/lll/nonamedreturns/revive/modernize/nilnil: named constants, wrapped
lines, unnamed returns, doc comments, SplitSeq, non-(nil,nil) returns.
- paralleltest/thelper: mark tests parallel (now race-safe with no shared
globals) and add t.Helper(); probe the real xattr key so the guard is
accurate.
Also make the tests actually runnable in CI rather than skipping:
- move the xattr keys into the user.* namespace (user.berlin.sneak.app.*),
which Linux requires for regular-file xattrs; macOS treats the whole
string as an opaque name, so behavior is unchanged there.
- run the Docker builder's checks as an unprivileged user so the permission
tests are meaningful (root bypasses file mode bits).
Instead of creating a new progress bar for each path, count total files
across all paths upfront and use a single unified progress bar. This
provides clearer UX when processing multiple directories.
- Add -q/--quiet flag to suppress all output except errors
- Add progress bar with 250ms refresh, file count, and ETA display
- Print summary report to stderr on completion (files processed, skipped, failed, bytes, duration)
- Support reading paths from stdin with "-" argument (e.g., find | attrsum sum add -)
- Update README with new features and updated TODO section
