feat(dependency): support local CRD dependencies - #537
Adds a local source for crd dependencies, as discussed in #93: the project file can now point at a CRD file, or a directory of CRDs, inside the project.
dependencies:
- type: crdlocal:
path: vendor/crds
This lets people vendor third-party CRDs and get schemas for them without putting them in apis/, which is meant for resources that go into the Configuration.
Following the thread on the issue:
The path has to be relative to the project directory and can't escape it (checked in Validate).
A directory is used as-is, so non-CRD files are ignored by the generators. A single file is exposed on its own so its siblings aren't picked up.
It reuses the schema manager's existing lock/version handling: the source is keyed as fs://<path> and versioned by a content hash, so project build / dependency update-cache only regenerate when the CRDs change.
crossplane dependency add treats an argument starting with ./, ../ or file:// as local, since anything else may be a valid xpkg reference. The path is resolved against the working directory and stored relative to the project; paths outside the project are rejected. --api-only is rejected like for the other non-xpkg sources.
Entries are de-duplicated by cleaned path.
I also ran this end to end with a built binary: dependency add ./vendor and dependency add ./vendor/thing.yaml on a scratch project wrote the expected entries and generated Python models for the CRD, and ../x was rejected.
One thing I left alone: the fs:// key can collide if someone points a local dependency at the same path as spec.paths.apis. That seemed too unusual to add handling for, but happy to if you'd like.
Tests: validation cases for the new field, localSource unit tests (directory, unclean path, single file, missing path), a manager test covering directory/file/dedup/missing/regeneration on change, and buildDependency tests for the CLI path handling.
Add a `local` source for `crd` dependencies in the project file, pointing
at a CRD file or a directory of CRDs inside the project:
dependencies:
- type: crd
local:
path: vendor/crds
This makes it possible to vendor third-party CRDs and generate schemas for
them without putting them in `apis/`, which is reserved for resources that
are built into the Configuration package.
Details:
- The path must be relative to the project directory and must not escape
it; this is enforced when the project file is validated.
- A directory is used as-is, so non-CRD files are ignored by the schema
generators. A single file is exposed on its own so its siblings are not
picked up.
- The source is identified in the schema lock file as `fs://<path>` and
versioned by a hash of its contents, so schemas are regenerated by
`project build` and `dependency update-cache` only when the CRDs change.
- `crossplane dependency add` recognizes local sources by a `./`, `../` or
`file://` prefix, since other strings may be valid xpkg references. The
path is resolved against the working directory and stored relative to the
project directory; paths outside the project are rejected.
- Entries are de-duplicated by cleaned path, so re-adding `./vendor/crds/`
updates the existing `vendor/crds` entry.

The dependency API and add command now support local CRD paths within a project. The dependency manager loads local files or directories as schema sources and records their versions.
The API adds and validates a local dependency path. The add command recognizes ./, ../, and file:// references, resolves paths within the project, and rejects local references with --api-only. Tests and help text cover local files and directories.
Local schema source internal/schemas/manager/source.go, internal/schemas/manager/source_test.go
A local source loads resources from a project filesystem path. Directory sources return the directory filesystem; file sources stage only the selected file. The source computes a version from its resources.
The manager adds local sources, returns their configured paths, and matches paths after cleaning. Tests cover lock entries, missing paths, and version changes after CRD content changes.
Local CRD dependencies work for the common case of single-document CRD files. Multi-document YAML bundles can silently skip CRDs after the first document, a renamed file may not trigger regeneration, and symlinks inside the project can reach files outside it. These are bounded edge cases worth fixing or acknowledging before or shortly after merge.

Explanation
The title "feat(dependency): support local CRD dependencies" is 48 characters, under the 72-character limit. It names the main change: a local source for CRD dependencies, which the changeset implements across the API types, validation, CLI, manager, and schema source.
Full details: Description check
Explanation
The description states the change clearly. It says the PR adds a local source for CRD dependencies that points to a file or directory inside the project. It covers path validation, the fs:// keying and hashing, CLI handling of ./, ../ and file:// arguments, de-duplication, and the tests added. It also links issue #93 that the change addresses.
Full details: Linked Issues check
Explanation
Thank you for this change. It meets the coding requirement of #93: support a local CRD dependency that points to a CRD file or directory. The reviewed summary shows these implementation points:
apis/dev/v1alpha1/project_types.go: Dependency.Local (LocalDependency.Path) adds the new source type.
apis/dev/v1alpha1/validate.go: LocalDependency.Validate rejects empty, absolute, and escaping paths. Dependency.Validate counts local as a source.
internal/schemas/manager/source.go: localSource and NewLocalSource load a directory as-is, or a single file alone. The source ID is fs://<path>, and the version is a content hash.
internal/dependency/manager.go: local dependencies are added through the project filesystem and matched by cleaned path.
Tests cover validation, localSource, manager add and regeneration on change, and CLI path handling. The summary does not show a missing requirement. The fs:// key collision with spec.paths.apis is a known edge case that the author raised. It does not block #93. Evidence source: PR description and the provided summary. No repository inspection was made.
Full details: Out of Scope Changes check
Explanation
The changes stay within the scope of #93. Each change supports the local CRD dependency:
API types and validation for the local source.
Schema source and manager support for the local path, including lock versioning.
dependency add handling of ./, ../, and file:// arguments, with project-boundary checks and --api-only rejection.
Help text for the add command, which feeds the generated reference docs.
Unit tests for each of these areas.
The zz_generated.deepcopy.go file is excluded from review by the ignored-files rule. Its absence does not affect this result. No unrelated change appears in the summary. Evidence source: PR description and the provided summary. No repository inspection was made.
Full details: Breaking Changes
Explanation
Changed files under apis/** and cmd/** were inspected from the reviewed diff range. No breaking change matches the check's failure conditions, so the breaking-change label does not affect this result. - Public fields: The only new public API field is Dependency.Local *LocalDependency. It is tagged json:"local,omitempty" and +optional, so it is not required. No existing public field is removed or renamed. zz_generated.deepcopy.go changes are the matching generated additions. - Flags and args: The dependency addPackage argument is still the same positional argument. Only its help text changed, and it now also lists local paths. No flag is removed, renamed, or made required. - Behavior: Existing source handling for xpkg, git, HTTP, and k8s is unchanged. The new local branch is added after existing branches. The only removed lines are the old exactly one source error text, which now also lists local, and the old help text. These are wording changes that accompany the new source type. They do not remove a supported behavior. - Signature:buildDependency gained a projDir parameter. It is an unexported method, so it is not a public API change. Reviewer note: the primary PR author was not needed for this check. The label state was not checked, because no failure condition applies.
Full details: Feature Gate Requirement
Explanation
Thank you for the careful work on this. The PR adds a new local source for crd dependencies, and it touches apis/dev/v1alpha1/** (new Local field and LocalDependency type in project_types.go, plus validate.go and deepcopy changes). The check fails only when a new experimental feature is added without a feature flag. The evidence does not establish that this feature is experimental, so the check does not fail. Evidence gathered: - The repo has an alpha gate. cmd/crossplane/main.go maps maturity.LevelAlpha to cfg.Features.EnableAlpha, and that flag must be set explicitly. Alpha commands are tagged maturity:"alpha", for example operation, xr, and simulate. - The dependency command is tagged maturity:"beta" (cmd/crossplane/main.go:92). Beta is enabled by default unless features.disableBeta is set. dependency add sits inside that beta command. The diff does not add a new maturity tag. - The PR does not describe the feature as experimental or alpha. The help text in add.md presents it as a normal dependency type. The PR says it fixes issue #93, a user-facing request. - The existing CRD git and http sources ship without a per-source flag. The new source follows the same pattern. - The apis/dev change adds a field. It does not introduce a flag-gated or alpha-only type. Caveat: the check does not define "experimental." If maintainers treat this beta-level, default-on source as experimental, the check would need a flag or alpha tag. This verdict depends on that classification.
Resolution
No change is required for this check. Before merge, maintainers should confirm the intended maturity for the local CRD source. If they want it treated as experimental, gate it behind an alpha flag (for example, a maturity:"alpha" annotation or an EnableAlpha check in dependency add and Dependency.Validate).

Include resource paths in the local-source version.
If a.YAML is renamed to a.yaml, this content-only hash does not change. However, the Python generator skips .YAML and accepts .yaml. After the first version is recorded without Python models, Manager.Add returns early after the rename and never generates the missing models. (raw.githubusercontent.com)
Please include normalized file paths and file boundaries in the hash. Add a regression case that records the source, renames the file, and checks that generation runs.

Enforce project containment when reading local resources.
If vendor/crds is a symlink to a directory outside the project, vendor/crds/example.yaml passes both lexical path checks. BasePathFs then delegates Stat and reads to the OS filesystem, so this code loads the external file. This violates the stated project-containment requirement. (raw.githubusercontent.com)
Please enforce containment at this resource boundary, including ancestor symlinks and files reached during directory traversal. A CLI-only check would not protect hand-written project files.
Based on learnings, lexical path validation does not resolve symlinks.

Handle YAML document streams before passing local files to generators.
If a vendored directory contains bundle.yaml with a ConfigMap followed by a CRD, this branch exposes the file unchanged. The Python generator unmarshals one TypeMeta and skips the file because its first document is a ConfigMap. The later CRD produces no Python models. sigs.k8s.io/yaml v1.6.0 delegates to a decoder that reads only the first document. (raw.githubusercontent.com)
Please split YAML streams into resource documents at this boundary, or make the generators stream-aware. Cover both directory and single-file sources. The documented contract says every CRD is used and other resources are ignored.
