| Summary: Next-generation license pattern matcher for Cavil | |
'Cavil::Matcher' turns source files into license and keyword matches for at https://github.com/openSUSE/cavil. It keeps the proven token-hash prefix-tree algorithm of its predecessor, Spooky::Patterns::XS, but stores the compiled patterns as immutable, memory-mapped *segments* described by a small *manifest*, so that adding or removing a pattern never rebuilds the whole cache and index workers share one physical copy of the data per host. The tokenizer and hashing are a frozen C++ core, bit-for-bit compatible with the previous engine; the segment lifecycle is pure Perl (see Cavil::Matcher::Index and Cavil::Matcher::Manifest). For the design and rationale see _docs/Architecture.md_.

- updated to 1.50.0 (1.05)
see /usr/share/doc/packages/perl-Cavil-Matcher/Changes
1.05 2026-09-03
- Removed the on-disk fingerprint index (fp_build/fp_open, the Cavil::Matcher::Fingerprints
package, and Cavil::Matcher::FpIndex); consumers now keep the searchable index in their own
database. The fingerprint_file and content_hash primitives are unchanged.
1.04 2026-08-27
- FpIndex now caches opened segments and reuses them across searches instead of reopening every
segment on every query. Opening a segment is a fixed per-query cost that otherwise dominated search
time on a long-lived query server, regardless of the query. Segments are immutable append-only
files, so a cached handle always maps the same bytes; a handle whose segment has been compacted out
of the manifest is dropped on the next search. Results are unchanged.
- score() and FpIndex::search() take an optional minimum containment; matches below it are dropped
inside the scorer instead of being returned for the caller to filter. A query dominated by common
fingerprints can match hundreds of thousands of contents, almost all coincidental, so applying the
floor at this level avoids building and returning them. Defaults to 0 (return everything).
- score() and FpIndex::search() also take an optional max_df: query fingerprints appearing in more
than that many records of a segment are ignored (boilerplate that matches nearly everything, adding
only coincidental hits and skewing containment). Off by default (0). Intended for a compacted
single-segment index, where a segment's record count for a fingerprint is its document frequency.
1.03 2026-08-27
- Fingerprint scoring now reports, for each matched fingerprint, the query fingerprint value it was,
appended to each region tuple after the existing start line and span. This lets a caller map
matches back to their query positions - enough to tell an aligned copy from scattered coincidental
hits, and to derive each query fingerprint's document frequency from a full result set. Backward
compatible: the (start_line, span) pair at the front of every region tuple is unchanged.
1.02 2026-08-27
- Snippet code search: a new winnowed-fingerprint index for "where does this code already exist"
provenance queries, alongside the license-pattern matcher. fingerprint_file winnows a file's
tokens (k tokens per gram, w grams per window) into content fingerprints; a fingerprint segment
stores them keyed by a 128-bit content hash rather than filenames (so it stays lean and joins to
the Cavil database), and scoring ranks candidates by both-direction containment with exact
matched-line spans for highlighting.
- Cavil::Matcher::FpIndex is the pure-Perl lifecycle over a directory of fingerprint segments
(incremental add_segment, manifest/generation, memory-mapped shared reads), reusing the same
on-disk discipline as the pattern index: versioned, CRC-checksummed, structure-validated on
every open, with corrupt or foreign files rejected rather than mis-read.
- Byte-identical files are de-duplicated by content hash, so the same source shipped across many
package versions is stored once, with no package-name parsing.
- Additive only: the license-pattern format is unchanged and no migration is needed.

- updated to 1.10.0 (1.01)
see /usr/share/doc/packages/perl-Cavil-Matcher/Changes
1.01 2026-08-04
- Big indexing speedup: the scan path (load/attach) no longer re-checksums a segment's whole
payload on every open. A compiled segment is an immutable, atomically-published cache that is
already CRC-checked when written, so re-CRCing hundreds of megabytes in every forked index job
was almost the entire cost of a load (~97% in a 160 MB corpus: ~293ms -> ~8ms). Structural
validation still always runs, so bad segments are rejected and scanning stays memory-safe;
only per-scan detection of on-disk bit-rot is dropped.
- CRC is now verified where it is meaningful: once at publish (dump() fully verifies before the
atomic rename) and on demand via the new Engine verify($file) method (an fsck for a cache dir).
- Same treatment for the closest-match "bag of patterns" cache (Bag::load, used by analyze): the
load path trusts the payload CRC (the record parse still bounds-checks every read), with a new
Bag verify($file) method and a publish-time check.
- No on-disk format change: existing segments load as-is, no reindex, and old/new engines
interoperate on the same files (in-place upgrade is seamless).
