From 186d1caf48ad71d584ecc6217849186c15ee7f9b Mon Sep 17 00:00:00 2001 From: Metbcy Date: Wed, 29 Apr 2026 20:40:41 -0700 Subject: [PATCH 1/7] feat(action): expose v0.7-v0.9.7 CLI flags as action.yml inputs Closes the action.yml/CLI parity gap. Every CLI flag that previously had to be driven through .bomdrift.toml or a direct cargo install is now a first-class action input: - VEX: vex (multi-line), emit-vex, vex-author, vex-default-justification - License policy: allow-licenses, deny-licenses, allow-exception, deny-exception, allow-ambiguous-licenses - Enrichment toggles: no-epss, no-kev, no-registry - Failure threshold: fail-on-epss - Calibration: recently-published-days, typosquat-similarity-threshold, young-maintainer-days, cache-ttl-hours, multi-major-delta (new in 0.9.7) - Attestation: before-attestation, after-attestation, cosign-identity, cosign-issuer, require-attestation - Plugins: plugin (multi-line) entrypoint.sh maps each input to the corresponding CLI flag through an extra_args array; empty inputs contribute nothing so existing workflows remain byte-identical. Multi-line inputs (vex, plugin) iterate one flag per non-empty line; comma-list inputs pass through as a single value. docs/src/github-action.md replaces the old single Inputs table with purpose-grouped reference tables (Core / Output / Suppression / License policy / Enrichment / Calibration / Failure thresholds / Attestation / Plugins / Release verification) and a 'What's new in v0.9.7' subsection listing the freshly exposed inputs.

The behavior is unchanged for v0.9.5 single-WITH cases — back-compat test asserts the bare matched_rule wording. For compound expressions (more than one leaf) the matched_rule now appends " (in )" so reviewers can locate the offending atom in expressions like '(Apache-2.0 WITH LLVM-exception) AND BSD-3-Clause'. Module doc-comment gains a 'WITH-chain inheritance' section that explains AND/OR semantics in plain English. Tests cover: AND with allowed exception permits; AND with denied exception violates and cites the leaf with compound context; OR with one allowed exception branch permits regardless of the sibling failure; OR with all exceptions denied violates; AND inherits exception denial from either side; back-compat regression for compound expressions without exceptions; SARIF/VEX synthetic id distinct between compound-exception and base-only violations.

Tests: - enrich_with default threshold matches enrich (back-compat) - threshold=1 trips on a single major bump (1.x → 2.x) - threshold=5 suppresses what default would flag (1.x → 4.x) - clap rejects 0 / -1 / non-numeric - smoke test that the flag wires through to a successful diff run Docs are owned by the platform agent (cli-reference.md update).

The crate provides a real platform-aware wait primitive — WaitForSingleObject on Windows; self-pipe + sigchld on Unix — making timeouts first-class on Windows instead of best-effort polling that could race the kill() against a finishing child. The protocol / JSON / finding-on-success path is unchanged; only the timeout-detection branch swaps to wait_timeout. Existing Unix-tagged plugin tests (success / timeout / non-zero-exit / malformed-JSON / two-plugin merge) all pass and now exercise the new code path.
