From d57cc2910b4e9419554c7080b4b619605d198b56 Mon Sep 17 00:00:00 2001 From: Copilot <223556219+Copilot@users.noreply.github.com> Date: Sat, 2 May 2026 23:49:52 +0200 Subject: [PATCH 1/2] fix(install): anchor transitive local deps on declaring package (#857) A package's local_path references are now anchored on that package's own directory (npm/pip/cargo workspace parity), not on the consumer's project root. Previously a transitive '../sibling' declared inside packages/specialized/apm.yml resolved against the consumer's root, making mono-repos with sibling helper packages non-portable. Changes: - APMPackage.source_path tracks the on-disk dir each package was loaded from. Cache key is (apm_yml_path, source_path) so two loads with different anchors don't collide. - Resolver threads parent_pkg through the download_callback Protocol; legacy callbacks without the kwarg keep working via a signature introspection fallback (False on TypeError/ValueError). - Resolve phase persists a dep_key -> base_dir map to ctx so the integrate phase can copy transitive locals with the right anchor. - _copy_local_package now requires project_root (no silent skip) and enforces ensure_path_within with a red error + actionable hint on PathTraversalError. - Resolver dual-rejects local_path declared by a remote parent (relative AND absolute) at ERROR severity. - Download failures surface via _rich_warning with exc_info on a separate _logger.debug call (no more bare except: pass). - SECURITY comments on symlinks=True (preserved intentionally) and the TOCTOU race window. Tests: cache-key distinctness, source_path threading on from_apm_yml, _is_remote_parent _local/ exclusion, signature fallback, containment boundary on _copy_local_package. Closes #857. Supersedes #940.

Previously a transitive `../sibling` declared inside `packages/specialized/apm.yml` was anchored on the **consumer**'s project root, which made shared workspace layouts (mono-repos, side-by-side helper packages) impossible to express portably -- the same `apm.yml` worked or broke depending on where the consumer lived in their tree. **Security tightening:** remote-cloned packages can no longer declare a local-filesystem `local_path` dependency (`ERROR` severity, fail-closed at resolve time, both relative and absolute paths rejected). Authors of remote packages who previously relied on `local_path` should switch the dependency to a published reference (`owner/repo` or marketplace handle) before upgrading. Sibling and monorepo layouts authored by the consumer (e.g. `apm install ../pkg-a`) continue to work unchanged. (#940, closes #857) Thanks @JahanzaibTayyab. - `apm compile` no longer silently drops instructions without an `applyTo` pattern from generated `AGENTS.md` and `CLAUDE.md`; globals now render under a `## Global Instructions` section, matching the optimizer's existing `(global)` placement (#1088, closes #1072) - `apm install` no longer masks local-bundle install failures with `UnboundLocalError`. (#PR_NUMBER) - **`apm install @` no longer fails for all marketplace packages.** The install resolver now accepts both legacy and current marketplace key names: `repository`/`repo` for github sources, `url`/`repo` for git-subdir sources, and `type`/`source` as the source-type discriminator. A scheme guard rejects full URLs passed through the `url` fallback.

C2 (rejected remote-parent local_path still installed): track rejected dep keys on ApmDependencyResolver._rejected_remote_local_keys, then fold them into ctx.callback_failures in resolve phase so integrate.py's existing skip gate honors the rejection. C3 (dep_base_dirs key collision): detect divergent-anchor writes in the build loop, _logger.warning loudly, keep first-write semantics. Comment documents that collision is latent today (BFS dedupes by unique key) but the guard is defensive against future BFS changes. C4/C5 (false containment claim in docs): drop the 'must stay inside consuming project root' wording from both packages/apm-guide and docs/src/content/docs; clarify sibling layouts work and the security boundary is upstream remote-parent rejection. C6 (CHANGELOG entry too long, wrong PR number): condense the 5-clause Fixed entry to a single line ending '(#1111, closes #857) Thanks @JahanzaibTayyab.' Tests: TestRemoteParentLocalPathFailClosed (2 tests) covers C2; test_copy_local_package_logger_none_does_not_raise covers C1. Verified: ruff check + format silent; 7241 unit tests pass.

Previously a transitive `../sibling` declared inside `packages/specialized/apm.yml` was anchored on the **consumer**'s project root, which made shared workspace layouts (mono-repos, side-by-side helper packages) impossible to express portably -- the same `apm.yml` worked or broke depending on where the consumer lived in their tree. **Security tightening:** remote-cloned packages can no longer declare a local-filesystem `local_path` dependency (`ERROR` severity, fail-closed at resolve time, both relative and absolute paths rejected). Authors of remote packages who previously relied on `local_path` should switch the dependency to a published reference (`owner/repo` or marketplace handle) before upgrading. Sibling and monorepo layouts authored by the consumer (e.g. `apm install ../pkg-a`) continue to work unchanged.

(#1111, closes #857) Thanks @JahanzaibTayyab. - `apm compile` no longer silently drops instructions without an `applyTo` pattern from generated `AGENTS.md` and `CLAUDE.md`; globals now render under a `## Global Instructions` section, matching the optimizer's existing `(global)` placement (#1088, closes #1072) - `apm install` no longer masks local-bundle install failures with `UnboundLocalError`. (#PR_NUMBER) - **`apm install @` no longer fails for all marketplace packages.** The install resolver now accepts both legacy and current marketplace key names: `repository`/`repo` for github sources, `url`/`repo` for git-subdir sources, and `type`/`source` as the source-type discriminator. A scheme guard rejects full URLs passed through the `url` fallback.
