From 86a65d640a47747950e55a06e669eae4d322613c Mon Sep 17 00:00:00 2001 From: Rongsong Shen Date: Sat, 18 Apr 2026 11:56:31 +0000 Subject: [PATCH] test(apiserver): add integration tests for P0+P1 backend features MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Covers ~30 integration tests across 8 sections from the apiserver-backend-integration-test-plan: - §1: Cluster config push (store population, merge semantics, zero-preserve) - §2: Host control (OnHostUpdated merge, validateHost, preCheck, batch ops) - §3: Resource value push (all 7 value types, nil/unknown discriminant, overwrite) - §4: Heartbeat keep-alive (interval update, zero-preserve) - §5: Cross-feature (config+heartbeat, config+host, worker+config field preservation) - §6: RBAC (cluster_admin bypass, algorithm confusion, expired tokens, hostgroup bypass) - §7: Store thread safety (concurrent config pushes, host control+config, resource values) - §8: Input safety (hostname length, empty lists, malformed payloads) All tests use CGO_ENABLED=0 with //go:build !cgo build tag. §8.1 hostname-length skipped pending P1-2b implementation. --- ...apiserver-backend-integration-test-plan.md | 459 ++++++++++++ src/docs/apiserver-backend-tasks.md | 22 +- src/frontend/apiserver/backend/clib.go | 11 +- src/frontend/apiserver/backend/convert.go | 3 +- .../apiserver/backend/integration_test.go | 505 +++++++++++++ src/frontend/apiserver/backend/val_helpers.h | 19 + .../apiserver/controllers/integration_test.go | 678 ++++++++++++++++++ .../apiserver/store/concurrency_test.go | 132 ++++ 8 files changed, 1805 insertions(+), 24 deletions(-) create mode 100644 src/docs/apiserver-backend-integration-test-plan.md create mode 100644 src/frontend/apiserver/backend/integration_test.go create mode 100644 src/frontend/apiserver/backend/val_helpers.h create mode 100644 src/frontend/apiserver/controllers/integration_test.go create mode 100644 src/frontend/apiserver/store/concurrency_test.go diff --git a/src/docs/apiserver-backend-integration-test-plan.md b/src/docs/apiserver-backend-integration-test-plan.md new file mode 100644 index 0000000..2a03d52 --- /dev/null +++ b/src/docs/apiserver-backend-integration-test-plan.md @@ -0,0 +1,459 @@ +# Integration Test Plan — P0 + P1 Features + +## Purpose + +Verify end-to-end correctness of every feature delivered by tasks P0-1 through P1-3, +exercising the full stack: handler → store → handler merge → store readback. +These tests **do not** require a live C controller or CGO — they use the pure-Go stores +and `DefaultHandler` directly, which is what unit tests already do. The integration layer +adds: **multi-step sequences**, **cross-feature interactions**, and **edge-case coverage** +that unit tests leave out. + +--- + +## Test Environment + +- All tests run with `CGO_ENABLED=0` (pure Go) +- Each test calls `store.InitStores()` to reset all global state +- `utils.Log = zap.NewNop()` to suppress log output +- **§1–§5, §7, §8**: call handler/store methods directly — no HTTP server required +- **§6 (RBAC)**: requires a test HTTP server via `httptest.NewRecorder` with a full Gin router; JWT tokens must be real HS256-signed tokens using the configured signing secret (typically `"xce-api-key"` in test config); `ctx.Set("user", "admin")` does **not** satisfy `GetUsernameFromToken()` which reads and parses the `Authorization` header + - **JWT IP binding:** `isValidToken` checks `claims.IP == ctx.ClientIP()`; in `httptest`, `ClientIP()` reads from `req.RemoteAddr` — set `req.RemoteAddr = "127.0.0.1:0"` on every test request and embed `"ip": "127.0.0.1"` in the JWT claims; a mismatch returns 401 for the wrong reason, silently invalidating the test + - **Auth config:** `isValidToken` dereferences `utils.AuthenticationYamlConfig`, a package-level pointer that is `nil` until `LoadConfig()` is called — before any JWT test set `utils.AuthenticationYamlConfig = &utils.Authentication{Token: utils.TokenConfig{SecretKey: "xce-api-key"}}` directly; do not call `LoadConfig()` (reads a file that won't exist in CI) + +--- + +## 1. P0-1: Cluster Config Push + +### 1.1 Config push populates all stores in a single call + +**Steps:** +1. Call `dispatchConfigPush(handler, queues, resources, hostConfigs, cluster)` with non-nil data for all four. +2. Verify `store.Queues`, `store.Resources`, `store.Hosts`, `store.Clusters` all contain the pushed data. + +**Asserts:** A single config push updates all four store types in sequence (queues → resources → hosts → cluster); the four updates are NOT atomic — a concurrent reader may see a partial state. + +### 1.2 Second config push merges (does not replace) + +**Steps:** +1. Seed `store.Hosts` with worker-sourced data (HostStatus, CPUFactor, NumCPUs, etc.) +2. Call `h.OnHostConfigUpdated()` with config-sourced fields (HostModel, HostType, MaxSlot) +3. Call `h.OnHostConfigUpdated()` a second time with `HostModel: "modelB"` (distinct from step 2's "modelA") +4. Verify worker-sourced fields from step 1 are still preserved +5. Verify `HostModel == "modelB"` (config-sourced field reflects the second push, not the first) + +**Asserts:** Partial merge is idempotent and correctly preserves the other source's fields across multiple pushes. + +### 1.3 Cluster update with zero HeartbeatInterval preserves existing value + +**Steps:** +1. `store.Clusters.Put("c1", ClusterInfo{HeartbeatInterval: 45})` +2. Call `h.OnClusterUpdated(&ClusterInfo{ClusterName: "c1", HeartbeatInterval: 0, Vcpus: 8})` +3. Verify `HeartbeatInterval` is still 45 (zero is ignored per `if incoming.HeartbeatInterval > 0` guard) + +**Asserts:** Cluster push with `HeartbeatInterval=0` does not zero out the stored interval. + +### 1.4 Config push with nil cluster argument is a no-op + +**Steps:** +1. Call `dispatchConfigPush(handler, nil, nil, nil, nil)` +2. Verify `store.Clusters.Count() == 0` + +**Covers:** `dispatchConfigPush` skips the cluster update when the cluster argument is nil. (The empty-name guard lives in the CGO layer `cClusterConfToClusterInfo` and is not reachable in `CGO_ENABLED=0` tests; a `ClusterInfo{ClusterName:""}` passed directly would be stored under an empty key.) + +### 1.5 Config push with nil queues/resources/hosts is safe + +**Steps:** +1. Call `dispatchConfigPush(handler, nil, nil, nil, nil)` +2. Verify no panics, no store entries. + +**Covers:** Nil-safety of the dispatch loop. + +--- + +## 2. P0-2: Host Control via Backend + +### 2.1 Valid control action (open/close) routes through to backend + +**Steps:** +1. `store.Hosts.Put("node01", HostInfo{HostName: "node01"})` +2. Call `preCheckHostControlRequest(&HostControlRequest{ControlAction: "open", Hostname: []string{"node01"}})` +3. Assert `allFlag == false`, `err == nil` + +**Asserts:** Valid actions pass pre-check. + +### 2.2 Invalid action is rejected + +**Steps:** +1. Call `preCheckHostControlRequest(&HostControlRequest{ControlAction: "reboot", Hostname: []string{"node01"}})` +2. Assert error is returned. + +**Asserts:** Only "open" and "close" are accepted. + +### 2.3 Comment length limit (512 chars) + +**Steps:** +1. Call `preCheckHostControlRequest` with `Comment` of 513 chars +2. Assert error +3. Call with 512 chars — assert no error + +**Already covered in unit tests.** Integration adds: verify the error message is human-readable. + +### 2.4 Hostname validation checks store existence + +**Steps:** +1. `store.Hosts.Put("node01", HostInfo{HostName: "node01"})` +2. Call `validateHost(ctx, action, []string{"node01", "nonexistent"})` +3. Assert `node01` in success list, `nonexistent` in failed map + +**Note:** `validateHost` calls `GetUsernameFromToken()` internally, requiring the same JWT setup as §6 — set `utils.AuthenticationYamlConfig`, set `req.RemoteAddr = "127.0.0.1:0"`, embed `"ip": "127.0.0.1"` in the JWT claims, and pass the token via `Authorization` header. `ctx.Set("user", "admin")` is **not** sufficient. See §6 Test Environment notes for the full setup checklist. Unlike §2.1–2.3, this test is grouped with the §6 JWT-required tests in `controllers/integration_test.go`. + +### 2.5 RBAC: host:control requires cluster_admin role + +**Steps:** +1. Load RBAC config with `cluster_admin` having `host:control` +2. Use `httptest.NewRecorder` + Gin router with a spy handler that sets a response body +3. Call with a user that is NOT cluster_admin — assert 403 response +4. Call with cluster_admin user — assert 2xx and spy handler body present + +**Note:** `RequirePermission` short-circuits for `cluster_admin` via early `return` (without calling `ctx.Next()`). Asserting `ctx.IsAborted() == false` gives a **false pass** — the middleware doesn't abort, but the handler is also never called. Use an HTTP recorder to verify the handler response actually appeared. + +**Covers:** Route middleware integration. + +### 2.6 RBAC: host:view accessible to basic_user + +**Steps:** +1. Load RBAC config with `basic_user` having `host:view` +2. Call `RequirePermission("host:view")` with basic_user +3. Assert request proceeds + +### 2.7 Concurrent control requests do not race + +**Already covered:** `TestPreCheckHostControlRequest_NoRace` (50 goroutines). +Integration adds: test that concurrent `ControlHost` calls to the same host don't corrupt store state. + +### 2.8 Batch response construction + +**Steps:** +1. Build success and failed slices directly (do NOT call `ControlHost` — it calls the CGO stub which returns `errNoCGO` under `CGO_ENABLED=0`): + - `succeededItems := []map[string]interface{}{{"node": "node01"}, {"node": "node02"}}` + - `failedItems := []map[string]interface{}{{"node": "bad", "reason": "not found"}}` +2. Call `BuildBatchOperationResponse("close", "host", succeededItems, failedItems)` +3. Verify returned status is `"partially_accepted"`, success list has 2 entries, failed map has 1 + +**Covers:** Batch response construction logic; the CGO backend call is out of scope for pure-Go integration tests. + +--- + +## 3. P1-1: Resource Value Push + +### 3.1 All 7 value types convert correctly (pure-Go path) + +**Steps:** +1. For each value type (i32, i64, u32, u64, fval, sval, bval): + - Create `rawResvalData` with that type + - Call `rawResvalToDistribution(r)` + - Assert `ValueType`, `NumericValue`/`StringValue`/`BooleanValue` match expected + +**Already covered in unit tests.** Integration adds: round-trip through `OnResourceLocationUpdated`: +2. Call `h.OnResourceLocationUpdated(rd)` for each type +3. Read back from `store.ResourceLocations` using composite key `name:host` +4. Assert stored values match + +### 3.2 Nil val produces nil return (no store update) + +**Steps:** +1. Create `rawResvalData{valNil: true, ...}` +2. Assert `rawResvalToDistribution` returns nil +3. Assert `store.ResourceLocations.Count() == 0` + +### 3.3 Unknown discriminant produces nil return with warn log + +**Steps:** +1. Create `rawResvalData{valWhich: 99, ...}` +2. Assert `rawResvalToDistribution` returns nil +3. Assert `store.ResourceLocations.Count() == 0` + +### 3.4 Multiple resource values in a single push + +**Steps:** +1. Call `h.OnResourceLocationUpdated(rd1)` then `h.OnResourceLocationUpdated(rd2)` with different `name:host` keys +2. Assert `store.ResourceLocations.Count() == 2` +3. Assert each key returns the correct value + +### 3.5 Resource value update overwrites previous value + +**Steps:** +1. `h.OnResourceLocationUpdated(rd)` with `NumericValue: 100.0` +2. `h.OnResourceLocationUpdated(rd)` with same `name:host` but `NumericValue: 200.0` +3. Assert stored value is 200.0 (last-write-wins) + +**Covers:** Store `Put` is a full replacement, not merge. + +### 3.6 Composite key format is `res_name:location` + +**Steps:** +1. Push a resource with `ResourceName: "mem"` and `Location: "node01"` +2. Assert `store.ResourceLocations.Has("mem:node01") == true` +3. Assert `store.ResourceLocations.Has("mem") == false` + +--- + +## 4. P1-3: Heartbeat Keep-Alive + +> **Isolation requirement:** `heartbeatIntervalSecs` is a package-level `var int32` in the `backend` package shared across all tests in that package. Tests in this section MUST NOT call `t.Parallel()`. Run the full heartbeat test group sequentially to avoid cross-test interference via `SetHeartbeatInterval`. + +### 4.1 Heartbeat interval updates on cluster config push + +**Steps:** +1. `atomic.StoreInt32(&heartbeatIntervalSecs, 30)` (default) +2. Call `h.OnClusterUpdated(&ClusterInfo{ClusterName: "c1", HeartbeatInterval: 45})` +3. Assert `atomic.LoadInt32(&heartbeatIntervalSecs) == 45` + +**Covers:** The P1-3 integration point — cluster config push triggers heartbeat interval change. + +### 4.2 Cluster push with HeartbeatInterval=0 preserves current interval + +**Steps:** +1. `atomic.StoreInt32(&heartbeatIntervalSecs, 45)` +2. Call `h.OnClusterUpdated(&ClusterInfo{ClusterName: "c1", HeartbeatInterval: 0})` +3. Assert `atomic.LoadInt32(&heartbeatIntervalSecs) == 45` (unchanged) + +**Covers:** The `> 0` guard in `OnClusterUpdated` and `SetHeartbeatInterval`. + +--- + +## 5. Cross-Feature Integration + +### 5.1 Config push updates heartbeat interval AND stores cluster data + +**Steps:** +1. Default `heartbeatIntervalSecs = 30` +2. Call `dispatchConfigPush(h, nil, nil, nil, &ClusterInfo{ClusterName: "c1", HeartbeatInterval: 60, Vcpus: 32})` +3. Assert `store.Clusters.Get("c1")` has `HeartbeatInterval=60, Vcpus=32` +4. Assert `atomic.LoadInt32(&heartbeatIntervalSecs) == 60` + +**Covers:** P0-1 + P1-3 interaction in a single dispatch. + +### 5.2 Config push + host control on same host + +**Steps:** +1. `dispatchConfigPush(h, nil, nil, []HostInfo{{HostName: "node01", HostModel: "x86_64"}}, nil)` +2. Assert `store.Hosts.Get("node01")` has `HostModel="x86_64"` +3. Assert `store.Hosts.Has("node01") == true` — verifies config-push data is visible in the host store +4. Call `preCheckHostControlRequest(&HostControlRequest{ControlAction: "close", Hostname: []string{"node01"}})` — assert `allFlag == false`, `err == nil` (validates action format; store lookup is handled by `validateHost` which requires JWT — see §2.4 note) + +**Covers:** Data created by config push is written to the host store and is visible to subsequent operations. + +### 5.3 Resource push after host config push — same host referenced + +**Steps:** +1. `h.OnHostConfigUpdated(&HostInfo{HostName: "node01", HostModel: "x86_64"})` +2. `h.OnResourceLocationUpdated(&ResourceDistributionInfo{ResourceName: "mem", Location: "node01", NumericValue: 65536.0, ValueType: NUMERIC, IsDynamic: true})` +3. Assert `store.Hosts.Get("node01")` has `HostModel="x86_64"` (preserved) +4. Assert `store.ResourceLocations.Get("mem:node01")` has `NumericValue=65536.0` +5. Assert `store.Hosts.Get("node01").HostModel` still "x86_64" (host config was not overwritten) + +**Covers:** Two independent push paths don't interfere with each other's store data. + +### 5.4 Worker push after config push preserves config fields + +**Steps:** +1. `h.OnHostConfigUpdated(&HostInfo{HostName: "node01", HostModel: "x86_64", MaxSlot: 8})` +2. `h.OnHostUpdated(&HostInfo{HostName: "node01", HostStatus: 3, CPUFactor: 2.5, NumCPUs: 16})` +3. Assert `got.HostModel == "x86_64" && got.MaxSlot == 8` (config preserved) +4. Assert `got.HostStatus == 3 && got.CPUFactor == 2.5` (worker updated) + +**Covers:** Two-push merge correctness — already tested in unit tests but verified here at integration scope. + +### 5.5 Multiple sequential config pushes (idempotent) + +**Steps:** +1. Push config with `ClusterInfo{Vcpus: 16, HeartbeatInterval: 30}` +2. Push config with `ClusterInfo{Vcpus: 32, HeartbeatInterval: 60}` +3. Assert store has `Vcpus=32, HeartbeatInterval=60` (last-write-wins for config fields) +4. Assert `heartbeatIntervalSecs == 60` + +**Covers:** Rapid config push updates don't leave stale data. + +--- + +## 6. RBAC Integration (End-to-End) + +> **RBAC isolation:** Call `resetRBACState()` (not `store.InitStores()`) at the start of each RBAC test. `resetRBACState()` zeros `rbacConfig`, preventing `AddPermissionsForRole` from appending duplicate permissions across test reloads. `store.InitStores()` does not reset RBAC state. + +### 6.1 Full middleware chain: JWT → RBAC → handler + +**Steps:** +1. Set up Gin router with real middleware (`RequirePermission("host:control")`) +2. Create a valid JWT token for a cluster_admin user +3. POST `/xce/v1/hosts/control` with `action=close, host_name=["node01"]` +4. Assert 202 Accepted (or mocked backend response) + +5. Create a valid JWT token for a basic_user +6. POST `/xce/v1/hosts/control` — assert 403 Forbidden + +7. POST `/xce/v1/hosts/select` with basic_user — assert passes (host:view) + +**Note:** This requires spinning up a test HTTP server via `httptest.NewRecorder`. Do not mock at the middleware level — the purpose of §6 is to exercise the real middleware chain end-to-end. + +### 6.2 RBAC: cluster_admin bypasses permission check + +**Steps:** +1. Set up Gin router with `RequirePermission("host:control")` +2. Sign a JWT for "admin1" with role "cluster_admin" and issue `POST /xce/v1/hosts/control` +3. Assert response status is **not 403** — verifies the middleware did not block the request + +**Note:** `RequirePermission` returns early for `cluster_admin` without calling `ctx.Next()`, so downstream handlers are **never reached**. Do not assert a spy handler body or `ctx.IsAborted() == false` — both give false results. To verify full handler execution for a privileged user, write a separate test with a non-cluster_admin user that has explicit `host:control` permission (see §6.3). + +### 6.3 RBAC: basic_user cannot control hosts but can view + +**Steps:** +1. Assign user "user1" role "basic_user" +2. Call `RequirePermission("host:control")` — assert 403 +3. Call `RequirePermission("host:view")` — assert passes + +### 6.4 JWT algorithm confusion is rejected + +**Steps:** +1. Configure test server with HS256 signing secret `"xce-api-key"` +2. Craft a token header claiming `"alg": "none"` or a mismatched algorithm (RS256) +3. POST to `/xce/v1/hosts/control` with that token (use valid IP binding so IP mismatch is not the cause of rejection) +4. Assert 401 Unauthorized +5. Assert response body contains a token/signature error string (e.g., `"token"`, `"invalid"`, or `"signature"`) — not `"ip"` or `"expired"` — to confirm the rejection is due to algorithm/signature failure, not an unrelated check + +**Covers:** Prevents algorithm confusion attacks where an attacker downgrades signing to `none`. + +### 6.5 Expired JWT is rejected + +**Steps:** +1. Sign a JWT with `exp = time.Now().Unix() - 3600` (expired 1 hour ago) +2. POST to any protected endpoint +3. Assert 401 Unauthorized + +**Covers:** Token replay after expiry — ensures expired tokens cannot be reused. + +### 6.6 Known gap: hostgroup domain restriction bypass + +> **Documents a known limitation, not a working feature.** `validateHost` at `hosts.go:505-507` contains a `// TODO` that silently skips hostgroup domain enforcement. This test makes the gap explicit so it is visible in code review and prevents accidental regression if the TODO is removed. + +**Steps:** +1. Provision a user with `host:control` scoped to hostgroup "gpu-nodes" +2. Issue `POST /xce/v1/hosts/control` targeting a host NOT in "gpu-nodes" +3. **Assert request is accepted** (not 403) — documents that hostgroup scoping is not yet enforced + +**Note:** When P1-2b implements hostgroup enforcement, flip this assertion to assert 403 and remove the `// TODO` marker. + +### 6.7 Post-logout token reuse + +> **Design gap:** JWTs are stateless and the current server does not maintain a JTI blacklist. A token valid at logout time remains valid until expiry. This test documents the current behavior as an explicit design decision. + +**Steps:** +1. Sign a valid JWT with a 1-hour expiry +2. Call `POST /xce/v1/users/logout` (or equivalent) — record any logout response +3. Immediately reuse the same token on `GET /xce/v1/hosts` — assert **200 OK** (not 401) + +**Note:** If a JTI blacklist is added in future, flip this assertion to expect 401 and add the blacklist provisioning step. + +--- + +## 7. Store Thread Safety + +> **CI requirement:** All §7 tests must run with `-race`: `go test -race ./store/...`. A test that passes without `-race` provides no guarantee of absence of data races — the Go race detector instruments memory accesses at runtime and is the authoritative check. + +### 7.1 Concurrent config pushes don't corrupt data + +**Steps:** +1. Start 10 goroutines, each calling `h.OnHostConfigUpdated(&HostInfo{HostName: "node01", ...})` with slightly different HostModel values +2. Wait for all goroutines to complete +3. Assert `store.Hosts.Get("node01")` returns a valid HostInfo (no zero-value corruption) +4. Assert `HostName` field is "node01" + +**Race detection note:** A simple value-validity assertion cannot prove absence of a data race — concurrent writes all produce plausible values. Run this test with `go test -race ./store/...` to detect RMW races via the Go race detector. The assertion above verifies structural integrity; `-race` detects the underlying race condition. + +### 7.2 Concurrent host control + config push + +**Steps:** +1. Goroutine A: call `OnHostConfigUpdated` for "node01" in a loop +2. Goroutine B: call `validateHost` checking "node01" existence in a loop +3. Assert no panics and no store corruption after 100 iterations + +### 7.3 Concurrent resource value pushes for same key + +**Steps:** +1. Start 10 goroutines, each calling `OnResourceLocationUpdated` for `"mem:node01"` with different NumericValue +2. Assert final stored value is one of the 10 values (no corruption) +3. Assert key exists exactly once + +--- + +## 8. Input Safety + +### 8.1 Hostname length limits + +> **Skip until P1-2b is implemented.** No hostname length validation exists in `preCheckHostControlRequest` yet — this test will pass vacuously. Add `//go:build p1_2b` build tag or comment out pending that task. + +**Steps:** +1. Call `preCheckHostControlRequest` with hostname exceeding the P1-2b limit (>1024 chars) +2. Assert `err != nil` with message indicating length exceeded + +### 8.2 Empty hostname list + +**Steps:** +1. Call `preCheckHostControlRequest` with `Hostname: []` +2. Assert `err != nil` — inspect the actual error message from `preCheckHostControlRequest` and assert it contains the expected string (e.g., "no hostnames provided" or similar) + +### 8.3 Select expression length (current limit: 4094) + +**Steps:** +1. Call handler with `Select` string > 4094 chars +2. Assert error +3. Call with 4094 chars — assert accepted + +### 8.4 Special characters in hostnames + +**Steps:** +1. Call with hostname containing `` +2. Assert the hostname is stored as a string without interpretation (XSS safety at API layer) + +--- + +## Test File Organization + +| File | Tests | +|------|-------| +| `backend/integration_test.go` | §1 (config push), §3 (resource push), §4 (heartbeat), §5 (cross-feature) | +| `controllers/integration_test.go` | §2.1–2.3, §2.5–2.8 (host control — no JWT required), §2.4 (host validation — **requires full JWT setup; see §6 prerequisites**), §6 (RBAC middleware), §8 (input safety) | +| `store/concurrency_test.go` | §7 (thread safety) | + +All test files use `//go:build !cgo` or `CGO_ENABLED=0` compatible patterns. + +**Package declarations:** +- `backend/integration_test.go` must declare `package backend` (not `package backend_test`) to access unexported symbols: `heartbeatIntervalSecs`, `rawResvalToDistribution`, `dispatchConfigPush` +- `controllers/integration_test.go` may use `package controllers_test` for black-box tests, but any test accessing unexported helpers must use `package controllers` + +**JWT signing secret in tests:** Integration tests in `controllers/integration_test.go` that create real JWTs must use a test-only signing secret (e.g., `"xce-api-key"` from the test config file).
