clawbot	c887f80f57	Escape tab, newline, CR and backslash in report paths (closes #7) ... A path holding a tab or newline split a row of the report or trees output. The path columns of both now write a backslash, tab, newline and carriage return as \\, \t, \n and \r; every other byte is written unchanged. Grouping and sorting still use the stored path. Warnings on stderr are escaped the same way in warnf, so each stays one line. In trees, the root directory's node now has the path "/" instead of an empty string, and its children's paths start with a single slash. README states the rule under "Report output format".

sneak	57efa64f18	Show progress while loading the record index ... On a database with tens of millions of records, indexing the existing rows before the walk takes real single-core time with no output, which is indistinguishable from a hang. Give the load its own spinner, and render every phase display the moment the phase starts instead of waiting for its first completed item.	2026-07-25 14:28:11 +07:00
sneak	b62b4f297f	Stat in the walk, hash only shared sizes, flush batches mid-scan ... Restructure scan into three phases: walk+stat, hash, update. The stat pass is folded into the walk workers: each regular file is lstatted as its directory is read, while the metadata is hot. The walk builds a scan-wide size census (walked files plus records outside the scan roots), and unchanged already-hashed files resolve during the walk without further work. Only files whose size at least one other file shares are ever read: a size-unique file cannot be a duplicate, so it is recorded without hashes (head and tail empty). When a later scan makes its size shared, the file is hashed then, even if otherwise unchanged. report excludes unhashed records; trees gives them a never-matching signature so a tree containing one never compares equal to another. Hashed records are committed in batched transactions while the hash phase runs, so an interrupted scan keeps everything hashed so far and the next run resumes cheaply. The hash phase total is exact, giving a meaningful ETA. Memory drops accordingly: the existing-record index holds only path, size, mtime, and a hashed flag (no hash values); the walk carries one small record per candidate file; overlapping operands are pruned up front instead of deduplicating every walked path in a scan-wide set. Files no bigger than one chunk are hashed with a single read.	2026-07-25 06:06:22 +07:00
sneak	065a533224	Make code lint-clean under the canonical golangci-lint config ... 150 findings fixed: linter autofixes for whitespace style (wsl_v5, nlreturn, noinlineerr), named returns removed, magic numbers replaced with named constants, static errNotRegular error, explicit Close/Parse error handling, unused cobra params renamed to _, and runReport/ runTrees/hashPass split into helpers to satisfy cyclop, gocognit, and funlen. Behavior verified unchanged against the README smoke test.	2026-07-23 05:36:05 +07:00
