sneak	e80c6541d2	Skip removed paths silently and fix the progress line (closes #133) ... A path removed while the scan runs gets no warning and no skipped count, in the walk or the hash phase. If the first of several hard links is gone, the next is read. Any other error is still warned about. On a terminal every display is the library's spinner, then the line. A phase with an exact total ends the padded line with its percent and a bar at a fixed column. sfdupes draws that bar: the library shows no spinner beside its own. The time remaining is labelled remain, not eta. Judgement call: an operand removed after the scan starts is passed over silently too. Deviation: README's 80-column promise for stalled lines is narrowed to its example. Model: opus-5-5	2026-10-26 04:06:11 +00:00
clawbot	68881f04f2	Store each hash as its raw 32 bytes in a BLOB column (closes #134) ... The head, tail and content columns of the files table are BLOB NOT NULL and hold the raw 32-byte SHA-256, half the size of the hex text, in the table and in the files_signature index. The hash phase, the records, report and trees carry each hash as a [sha256.Size]byte and compare it with ==; nothing is hex-encoded. Reading a record whose hash column is not 32 bytes is an error naming its path. In the tests, testHash is a stand-in hash: a string's bytes padded with zeros, so fixtures keep the sort order their strings give. Judgement call: a hash of the wrong length is refused on reading, not copied silently. Model: opus-5-5	2026-10-26 03:15:38 +01:00
clawbot	f7a746f912	Hash every file's head, tail and content in the hash phase (closes #132) ... Every file the walk records now gets three hashes: head and tail, of its first and last 64 KiB, and content. The content hash covers the whole file under 100 MiB, and 1 MiB at each gigabyte from 100 MiB up, so a large file is never read in full. One 100 MiB constant replaces the 10 MiB and 50 MiB thresholds. The size census, the records stored without hashes and the content phase are gone, so a rescan reads only new and changed files. report and trees no longer special-case a missing content hash. README "Duplicate detection" and "Rationale" are rewritten. Judgement call: info drops its two hash-count lines, which now always equal the record count. Model: opus-5-5	2026-10-26 02:02:48 +01:00
clawbot	e9e09effc6	Add sfdupes info: show the database's details (closes #117) ... info prints the database's path and source, the sizes of the database file and its -wal file, when the database file last changed, the schema version and the record counts, one per line as a name, a tab and the value. It opens the database as report does and shows an open and a count phase on stderr. The schema version and the counts come from one read-only transaction, the counts from one query. seedDatabase now closes test databases out of WAL mode, as scan does; otherwise info's own connection creates an empty -wal file. The open phase's name and text became constants for the linter, and the scan command moved to newScanCommand to keep newRootCommand short enough. Judgement call: the lines are written after the last display ends, so they skip the display's stdout writer. Model: opus-5-5	2026-10-16 22:41:16 +02:00
