Summary

Re-point BytePort's NVMS parser from local implementation to the shared phenotype-tooling/nanovms/parser package as part of cross-repo consolidation (epic B).

Context

BytePort contained a local NVMS configuration parser (backend/nvms/) that duplicated parser logic. As part of epic B's cross-repo consolidation, this parser has been extracted into phenotype-tooling/crates/nanovms/parser so it can be shared across the phenotype ecosystem (BytePort, phenotype-sdk, etc.). This PR redirects BytePort's references to the external shared package.

Changes

  • go.mod: Added github.com/kooshapari/nanovms v0.0.0 dependency with replace directive pointing to ../../../phenotype-tooling/crates/nanovms
  • models/types.go: Replaced local NVMS, Service, and BuildPack struct definitions with type aliases pointing to parser.NVMS, parser.Service, parser.BuildPack — maintaining full backward compatibility
  • projectManager/parser.go: Replaced 60-line local parseNVMSConfig implementation with a thin delegation to parser.ParseNVMSConfig

Key Implementation Details

  • Uses Go type aliases (=) rather than type definitions, so all existing usages of models.NVMS, models.Service, models.BuildPack continue to compile without changes
  • The replace directive uses a relative path to the local clone so no remote publish is needed yet — the external package lives in the same monorepo-adjacent workspace
  • AWS-specific types (AWSConfig, AWSResource, etc.) remain local since they are BytePort-specific

Testing

cd backend/nvms
go mod tidy
go build ./models
go vet ./models

The models package builds and vets cleanly. The projectManager package has a pre-existing build failure from fermyon/spin-go-sdk (unrelated export comment mismatch) that exists on main as well.

CodeAnt-AI Description

Use the shared NVMS parser for config loading

What Changed

  • NVMS config parsing now uses the shared parser package instead of BytePort’s local copy
  • Existing NVMS model types now point to the shared parser types, so current code can keep using the same names
  • BytePort now depends on the shared parser package directly

Impact

✅ Consistent NVMS parsing across tools
✅ Fewer parser mismatches
✅ Easier NVMS parser updates

P1 Badge Pin the parser to an available module

In a normal BytePort checkout, this replacement resolves relative to backend/nvms/go.mod as /workspace/phenotype-tooling/crates/nanovms, which is not part of this repo; I checked the workspace and go list ./models reports replacement directory ../../../phenotype-tooling/crates/nanovms does not exist. Since the new imports in models/types.go and projectManager/parser.go depend on this module, the backend/nvms CI jobs that run go build ./... will fail unless every builder has a sibling phenotype-tooling checkout at exactly that path.

Useful? React with 👍 / 👎.

Suggestion: The replace points to a local relative path outside this repository, so fresh checkouts/CI runners that only clone BytePort will fail module resolution (github.com/kooshapari/nanovms cannot be found). Use a resolvable module source for shared builds (published version or vendored/submodule path available in CI), or gate the local replace to developer-only workflows. [api mismatch]

Severity Level: Major ⚠️
-`backend/nvms` module fails to build standalone.
- ❌ Go tooling unusable without extra sibling repo checkout.
- ⚠️ CI runners cloning only BytePort may break builds.
Steps of Reproduction ✅
1. Clone only the BytePort repository into a clean workspace so that the relative sibling
path `../../../phenotype-tooling/crates/nanovms` does not exist on disk.

2. From the `backend/nvms` directory containing `go.mod` with `replace
github.com/kooshapari/nanovms => ../../../phenotype-tooling/crates/nanovms` at line 25,
run `go mod tidy` or `go build ./...`.

3. The Go module resolution attempts to apply the `replace` directive for
`github.com/kooshapari/nanovms` and tries to read the module from
`../../../phenotype-tooling/crates/nanovms`, which is missing in this checkout.

4. The Go tooling reports an error similar to `stat
../../../phenotype-tooling/crates/nanovms: no such file or directory` and the
`backend/nvms` module fails to build in environments that only have the BytePort repo.
