diff --git a/CHANGELOG.md b/CHANGELOG.md index aafc1c556..1376d9bfc 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -17,6 +17,7 @@ First tagged release. ### Fixed +- **Project config provider keys** (`config`, `internal/backend`, `internal/acp`) — a project `.harness.json` cannot set `auth` or `api_key_env` on any provider, and cannot set `base_url`, `responses_path`, `extra_headers`, or `permission_mode` on a provider that the user config defines or that is built in (`anthropic`, `openai`). `LoadProject` fails with an error that names the key, the provider, and both files, in place of a warning and a dropped key. A project file can still define a new provider with an endpoint, and that provider sends no API key. Only the built-in `openai` entry reads `OPENAI_API_KEY` by default; an `openai` type entry under another name needs `api_key_env` in the user config. `harness acp` sends the load error in `data.reason` of the `session/new` error. This stops a checkout from sending an API key, or any environment variable, to an endpoint it chooses. - **Project config trust model** (`docs/architecture.md`, `README.md`) — the spec states that a project `.harness.json` is code, lists the keys that start a process or connect out (`binary_path`, `extra_args`, `permission_mode`, `api_key_env`, `mcp_servers`, `plugins`, `processes`, and the endpoint keys of `providers`), and advises that a user not open an untrusted checkout and that an embedder pass its own config and isolate the process. No behavior changes. - **Proxy base before validation** (`config`, `cmd/harness-wasm`, `sdk/embed`) — `proxy.baseURL` fills the `base_url` of a `providers` entry before the config is validated, so an entry of type `openai` with no `base_url` is valid in a browser or Node host that sets the proxy. `config.MergeProject` takes the proxy base as its last argument. `sdk/embed/README.md` and the WebAssembly section describe the same-origin proxy pattern and the demo-only direct Anthropic setup with `extra_headers`. - **Load answer order** (`internal/acp`) — the event pump of a session that `session/load` or `session/resume` opens queues its updates until the answer is sent. A record that the log gains between the read and the open no longer reaches the client before the answer. diff --git a/config/auth_test.go b/config/auth_test.go index 8c3d26909..d1c2ed144 100644 --- a/config/auth_test.go +++ b/config/auth_test.go @@ -51,28 +51,6 @@ func TestProjectConfigCannotSetTheCodexLoginFiles(t *testing.T) { } } -func TestProjectFileCannotMoveTheLogin(t *testing.T) { - user := &Config{Providers: map[string]Provider{"codex": {Type: TypeOpenAI, Auth: AuthChatGPT, BaseURL: "https://chatgpt.com/backend-api/codex", ResponsesPath: "/responses"}}} - project := &Config{Providers: map[string]Provider{ - "codex": {Auth: "other", BaseURL: "https://evil.example", ResponsesPath: "/evil", OmitResponseParams: []string{OmitResponseParamTopP}}, - "fresh": {Type: TypeOpenAI, Auth: AuthChatGPT, BaseURL: "https://evil.example"}, - }} - merged, err := mergeAndValidate(user, project) - if err != nil { - t.Fatal(err) - } - got := merged.Providers["codex"] - if got.Auth != AuthChatGPT || got.BaseURL != user.Providers["codex"].BaseURL || got.ResponsesPath != "/responses" { - t.Errorf("codex entry = %+v, want the user auth, base_url, and responses_path", got) - } - if len(got.OmitResponseParams) != 1 { - t.Errorf("omit_response_params = %v, want the project value, which does not move the login", got.OmitResponseParams) - } - if merged.Providers["fresh"].Auth != "" { - t.Errorf("fresh auth = %q, want none: a project file cannot set auth", merged.Providers["fresh"].Auth) - } -} - func TestCodexIssuerHasNoEnvironmentVariable(t *testing.T) { c := &Config{} env := map[string]string{"HARNESS_CODEX_ISSUER": "http://remote.example", "HARNESS_CODEX_AUTH_FILE": "/tmp/codex.json"} diff --git a/config/config_test.go b/config/config_test.go index fda5e0364..3e3cd1a40 100644 --- a/config/config_test.go +++ b/config/config_test.go @@ -836,7 +836,7 @@ func TestLoadProject(t *testing.T) { writeFile(t, filepath.Join(projDir, ".harness.json"), `{ "model": "openai/gpt-5", "aliases": {"smart": "openai/gpt-5-pro"}, - "providers": {"anthropic": {"base_url": "http://project"}} + "providers": {"anthropic": {"cache_ttl": "1h"}} }`) c, err := LoadProject(userPath, projDir) if err != nil { @@ -858,8 +858,8 @@ func TestLoadProject(t *testing.T) { if got.APIKeyEnv != "USER_KEY" { t.Errorf("anthropic api_key_env = %q, want inherited USER_KEY", got.APIKeyEnv) } - if got.BaseURL != "http://project" { - t.Errorf("anthropic base_url = %q, want project override", got.BaseURL) + if got.BaseURL != "http://user" || got.CacheTTL != "1h" { + t.Errorf("anthropic base_url, cache_ttl = %q, %q, want the user URL and the project TTL", got.BaseURL, got.CacheTTL) } }) // A project-only providers entry naming an unknown key with no type is diff --git a/config/load.go b/config/load.go index 5e3241654..b03001af7 100644 --- a/config/load.go +++ b/config/load.go @@ -5,8 +5,10 @@ import ( "encoding/json" "errors" "fmt" + "maps" "os" "path/filepath" + "slices" "strings" ) @@ -60,10 +62,47 @@ func MergeProject(user *Config, userName, dir, proxyBase string) (*Config, error if err := rejectSharedPlugins(user, proj, userName, projPath); err != nil { return nil, err } + if err := rejectProjectProviderKeys(user, proj, userName, projPath); err != nil { + return nil, err + } out := merge(user, proj).WithProxyBase(proxyBase) return &out, out.Validate() } +// rejectProjectProviderKeys fails when the project file sets auth, sets api_key_env on any provider, or +// sets a key that picks the endpoint of a request on a provider that the user config defines or that is +// built in.
