The engine/platform check in `#checkEngineAndPlatform` only skipped optional deps, not deps excluded via the --omit flag. Additionally, the logic determining whether a node should be omitted was duplicated across three modules (build-ideal-tree, reify, audit-report). Solution: Centralize the omit-matching logic into a stateless `Node.shouldOmit(omitSet)` predicate and call it from all three consumers. The method accepts both Set and Array inputs, caches nothing on the node, and documents the devOptional semantics: a node in the overlap of the dev and optional trees is only omitted when both 'dev' and 'optional' are in the set. - build-ideal-tree: gate engine/platform checks on shouldOmit - reify: replace #omitDev/#omitPeer/#omitOptional with single #omitSet - audit-report: replace inline logic in shouldAudit with shouldOmit - package.json: pin all dependency versions to exact ranges - tests: unit tests for shouldOmit (boundary, coercion, statelessness) and integration tests for the engine-strict + omit-dev scenario Co-Authored-By: Claude Sonnet 4.6 --- .../arborist/lib/arborist/build-ideal-tree.js | 3 +- workspaces/arborist/lib/arborist/reify.js | 18 +-- workspaces/arborist/lib/audit-report.js | 8 +- workspaces/arborist/lib/node.js | 37 +++++ workspaces/arborist/package.json | 84 +++++------ .../test/arborist/build-ideal-tree.js | 20 +++ .../package-lock.json | 32 ++++ .../dev-engine-specification/package.json | 11 ++ workspaces/arborist/test/node.js | 139 ++++++++++++++++++ 9 files changed, 288 insertions(+), 64 deletions(-) create mode 100644 workspaces/arborist/test/fixtures/dev-engine-specification/package-lock.json create mode 100644 workspaces/arborist/test/fixtures/dev-engine-specification/package.json diff --git a/workspaces/arborist/lib/arborist/build-ideal-tree.js b/workspaces/arborist/lib/arborist/build-ideal-tree.js index a7e01fcf14801..18a98ec95c7b7 100644 --- a/workspaces/arborist/lib/arborist/build-ideal-tree.js +++ b/workspaces/arborist/lib/arborist/build-ideal-tree.js @@ -193,8 +193,9 @@ module.exports = cls => class IdealTreeBuilder extends cls { async #checkEngineAndPlatform () { const { engineStrict, npmVersion, nodeVersion } = this.options + const omit = new Set(this.options.omit || []) for (const node of this.idealTree.inventory.values()) { - if (!node.optional) { + if (!node.optional && !node.shouldOmit(omit)) { try { // if devEngines is present in the root node we ignore the engines check if (!(node.isRoot && node.package.devEngines)) { diff --git a/workspaces/arborist/lib/arborist/reify.js b/workspaces/arborist/lib/arborist/reify.js index 796be4fa507c4..9e2e9687497a6 100644 --- a/workspaces/arborist/lib/arborist/reify.js +++ b/workspaces/arborist/lib/arborist/reify.js @@ -84,9 +84,7 @@ module.exports = cls => class Reifier extends cls { #bundleUnpacked = new Set() // the nodes we unpack to read their bundles #dryRun #nmValidated = new Set() - #omitDev - #omitPeer - #omitOptional + #omitSet = new Set() #retiredPaths = {} #retiredUnchanged = {} #savePrefix @@ -110,10 +108,7 @@ module.exports = cls => class Reifier extends cls { throw er } - const omit = new Set(options.omit || []) - this.#omitDev = omit.has('dev') - this.#omitOptional = omit.has('optional') - this.#omitPeer = omit.has('peer') + this.#omitSet = new Set(options.omit || []) // start tracker block this.addTracker('reify') @@ -562,7 +557,7 @@ module.exports = cls => class Reifier extends cls { // adding to the trash list will skip reifying, and delete them // if they are currently in the tree and otherwise untouched.
