cmd/server/service/providers.go (1)
97-110: Fail fast when both AUTH0_TENANT and AUTH0_DOMAIN are unsetIf both are empty,
auth0Domainbecomes “.auth0.com” and defers failure to runtime. Prefer explicit configuration failure.Apply this diff (and keep existing logging):
auth0Tenant := os.Getenv(constants.Auth0TenantEnvKey) auth0Domain := os.Getenv(constants.Auth0DomainEnvKey) + if auth0Tenant == "" && auth0Domain == "" { + log.Fatalf("missing Auth0 configuration: either %s or %s must be set", + constants.Auth0TenantEnvKey, constants.Auth0DomainEnvKey) + } + slog.DebugContext(ctx, "using Auth0 user repository implementation", "tenant", auth0Tenant, "domain", auth0Domain, ) if auth0Domain == "" { // Default to tenant.auth0.com if domain is not explicitly set auth0Domain = fmt.Sprintf("%s.auth0.com", auth0Tenant) }Based on learnings
Also applies to: 121-127
internal/infrastructure/auth0/user.go (1)
6-22: Import net/url for safe query encoding.We need URL-escape query params.
Apply this diff:
import ( "context" "fmt" "log/slog" "net/http" + "net/url" "slices" "strings" "time"
🧹 Nitpick comments (23)
pkg/converters/pointers_test.go (1)
58-61: Optional: drop the address-comparison check to reduce brittleness.Comparing &tt.input to the returned pointer depends on loop-scoped variables; the primary contract (returned pointer points to a copy) is already validated by TestStringPtrModification.
- // Verify it's actually a different address than the input - if &tt.input == result { - t.Error("StringPtr() returned pointer to input variable instead of creating new pointer") - } + // Implicitly validated by TestStringPtrModification; address comparison can be brittle in table-driven loops.pkg/redaction/redaction.go (2)
59-72: Prefer strings.Cut over Split for emails.Saves an allocation and handles “no @” cleanly.
- parts := strings.Split(email, "@") - if len(parts) != 2 { - // Invalid email format, redact the whole thing - return Redact(email) - } - - localPart := parts[0] - domain := parts[1] + localPart, domain, ok := strings.Cut(email, "@") + if !ok || domain == "" { + // Invalid email format, redact the whole thing + return Redact(email) + }
13-22: Add unit tests to lock behavior.Recommend adding table tests for Redact/RedactEmail (ASCII, Unicode, edge cases).
I can generate a redaction_test.go with table-driven cases if helpful.
pkg/httpclient/request.go (1)
26-34: Endpoint field appears unused.If not used in URL building, consider removing to reduce confusion or wire it into URL composition.
cmd/server/service/message_handler.go (2)
28-31: Minor perf: avoid per-call map allocation.Replace the ephemeral map with a switch or precomputed map on the struct to reduce allocations on hot paths.
Example switch:
switch subject { case constants.UserMetadataUpdateSubject: response, errHandler = mhs.messageHandler.UpdateUser(ctx, msg) case constants.UserEmailToUserSubject: response, errHandler = mhs.messageHandler.EmailToUsername(ctx, msg) default: // existing unknown subject path... }
56-57: Consider reducing response logging.Response may include usernames; consider logging length or hash at debug.
- slog.DebugContext(ctx, "responded to NATS message", "response", string(response)) + slog.DebugContext(ctx, "responded to NATS message", "response_len", len(response))internal/domain/port/user.go (1)
21-21: Clarify criteria contract (email/username) and prefer typed constants.Add a brief doc comment that valid criteria are constants.CriteriaTypeEmail and constants.CriteriaTypeUsername to avoid misuse downstream.
charts/lfx-v2-auth-service/values.yaml (1)
32-45: Add optional AUTH0_ORGANIZATION and secret sourcing hint.Token manager supports organization; include it as optional. Also consider sourcing these via Kubernetes Secrets, not plain values.
Proposed additions:
AUTH0_DOMAIN: value: null + # Optional organization for M2M context + AUTH0_ORGANIZATION: + value: nullinternal/domain/port/message_handler.go (1)
8-11: Minor doc nit: fix grammar in interface comment“The behavior of the all domain handlers” → “the behavior of all domain handlers”.
Apply this diff:
-// MessageHandler defines the behavior of the all domain handlers +// MessageHandler defines the behavior of all domain handlerscmd/server/service/providers.go (3)
145-147: Reuse a single UserReaderWriter instance (avoid double initialization and extra M2M token managers)
newUserReaderWriter(ctx)is invoked twice, creating two clients/token managers. Reuse one instance for both reader and writer wiring.Apply this diff:
- messageHandlerService := &MessageHandlerService{ - messageHandler: service.NewMessageHandlerOrchestrator( - service.WithUserWriterForMessageHandler( - service.NewUserWriterOrchestrator(service.WithUserWriter(newUserReaderWriter(ctx))), - ), - service.WithUserReaderForMessageHandler( - service.NewuserReaderOrchestrator(service.WithUserReader(newUserReaderWriter(ctx))), - ), - ), - } + userRW := newUserReaderWriter(ctx) + + messageHandlerService := &MessageHandlerService{ + messageHandler: service.NewMessageHandlerOrchestrator( + service.WithUserWriterForMessageHandler( + service.NewUserWriterOrchestrator(service.WithUserWriter(userRW)), + ), + service.WithUserReaderForMessageHandler( + service.NewuserReaderOrchestrator(service.WithUserReader(userRW)), + ), + ), + }Also applies to: 140-149
116-119: Log message suggests success before construction; tweak phrasingChange “initialized” → “initializing” or move the log after successful construction.
Apply this diff:
- slog.DebugContext(ctx, "Auth0 client initialized with M2M token support", + slog.DebugContext(ctx, "initializing Auth0 client with M2M token support", "tenant", auth0Tenant, "domain", auth0Domain, )
6-15: Optional: unify logging (log vs slog) for consistencyYou mix stdlib log.Fatalf and slog.*. Consider standardizing on slog (e.g., slog.ErrorContext + os.Exit) for uniformity.
Also applies to: 46-47, 55-56, 64-65, 74-77
internal/service/user_reader.go (4)
6-11: Prepare for error returns: import fmtNeeded for new error paths suggested below.
Apply this diff:
import ( "context" + "fmt" "github.com/linuxfoundation/lfx-v2-auth-service/internal/domain/model" "github.com/linuxfoundation/lfx-v2-auth-service/internal/domain/port" )
24-32: Comment accuracy: “writer” → “reader”Fix option doc to match the reader orchestrator.
Apply this diff:
-// userReaderOrchestratorOption defines the option for the user writer orchestrator +// userReaderOrchestratorOption defines options for the user reader orchestrator @@ -// WithUserReader sets the user writer for the user writer orchestrator +// WithUserReader sets the user reader for the user reader orchestrator
34-37: Guard against nil dependency to avoid panicsReturn a clear error if the orchestrator is constructed without a UserReader.
Apply this diff:
-// UpdateUser updates the user in the identity provider func (u *userReaderOrchestrator) GetUser(ctx context.Context, user *model.User) (*model.User, error) { - return u.userReader.GetUser(ctx, user) + if u == nil || u.userReader == nil { + return nil, fmt.Errorf("userReader is not configured") + } + return u.userReader.GetUser(ctx, user) }
39-41: Guard SearchUser similarlyAvoid nil deref on missing dependency.
Apply this diff:
func (u *userReaderOrchestrator) SearchUser(ctx context.Context, user *model.User, criteria string) (*model.User, error) { - return u.userReader.SearchUser(ctx, user, criteria) + if u == nil || u.userReader == nil { + return nil, fmt.Errorf("userReader is not configured") + } + return u.userReader.SearchUser(ctx, user, criteria) }internal/infrastructure/auth0/token.go (2)
6-21: Validate domain before creating the Auth0 client.Guard against empty config.Domain for a clearer failure early.
Apply this diff:
import ( "context" "encoding/base64" "fmt" "log/slog" "net/http" "os" + "strings" "time"And in NewM2MTokenManager:
func NewM2MTokenManager(ctx context.Context, config Config) (*TokenManager, error) { + if strings.TrimSpace(config.Domain) == "" { + return nil, errors.NewValidation("Auth0 domain configuration is missing") + } m2mConfig, err := loadM2MConfigFromEnv(ctx, config)
104-111: IsTokenExpired may refresh tokens implicitly.Calling Token() on a ReuseTokenSource can fetch/refresh a token, making this check always “not expired”. Consider tracking last token and checking its Expiry without triggering refresh.
internal/infrastructure/auth0/user_test.go (2)
812-819: Simplify substring helper.Use strings.Contains for clarity and correctness; current implementation is overcomplicated and error-prone.
Apply this diff:
+import "strings" @@ func containsString(s, substr string) bool { - return len(s) >= len(substr) && (s == substr || - (len(s) > len(substr) && - (s[:len(substr)] == substr || - s[len(s)-len(substr):] == substr || - containsSubstring(s, substr)))) + return strings.Contains(s, substr) } -func containsSubstring(s, substr string) bool { - for i := 0; i <= len(s)-len(substr); i++ { - if s[i:i+len(substr)] == substr { - return true - } - } - return false -} +// containsSubstring is no longer needed.
18-183: Add SearchUser unit tests.No tests assert email/username search behavior, connection filtering, URL-encoding of inputs, or M2M token fallback. Add table tests for:
- email with plus/uppercase → downcased and URL‑encoded, /users-by-email primary then /users fallback.
- username → search via /users and post-filter connection.
- missing domain → validation error.
Also applies to: 219-306, 308-343, 345-409, 411-559, 561-629, 631-695, 697-793
internal/infrastructure/auth0/user.go (3)
156-163: Don’t mutate input user.Token; use a local variable and fallback to M2M.Avoid side effects on the input model.
Apply this diff:
- if user.Token == "" { - m2mToken, errGetToken := u.config.M2MTokenManager.GetToken(ctx) + tokenToUse := strings.TrimSpace(user.Token) + if tokenToUse == "" { + m2mToken, errGetToken := u.config.M2MTokenManager.GetToken(ctx) if errGetToken != nil { return nil, errors.NewUnexpected("failed to get M2M token", errGetToken) } - user.Token = m2mToken + tokenToUse = m2mToken }And use tokenToUse below:
- httpclient.WithToken(user.Token), + httpclient.WithToken(tokenToUse),
164-171: Safer URL construction.Keep endpoint templates and only substitute encoded values.
Apply this diff:
- endpointWithParam := fmt.Sprintf(endpoint, param(criteria)) - url := fmt.Sprintf("https://%s/api/v2/%s", u.config.Domain, endpointWithParam) + endpointWithParam := fmt.Sprintf(endpoint, param(criteria)) + url := fmt.Sprintf("https://%s/api/v2/%s", u.config.Domain, endpointWithParam)Note: With the earlier change, param(criteria) is URL-encoded; keep the template strings unencoded.
190-200: Avoid shadowing parameter ‘user’.Rename loop variable to improve readability.
Apply this diff:
- for _, user := range users { + for _, au := range users { // identities.user_id:{{username}} AND identities.connection:Username-Password-Authentication // It doesn't work like an AND, it works like an OR // So it's necessary to check if the identity is the one we are looking for - for _, identity := range user.Identities { + for _, identity := range au.Identities { if identity.Connection == usernameFilter { - user.Username = identity.UserID - return user.ToUser(), nil + au.Username = identity.UserID + return au.ToUser(), nil } } }

Timestamp: 2025-09-22T14:09:00.504Z
Learning: In the LFX v2 Auth Service, mauriciozanettisalomao prefers explicit failure over silent fallbacks when Auth0 configuration (AUTH0_TENANT, AUTH0_DOMAIN) is incomplete. The service should continue with the Auth0 implementation and fail later during actual connection attempts rather than falling back to mock behavior, as this provides clearer debugging context and avoids masking configuration issues.

pkg/redaction/redaction_test.go (1)
10-131: Thorough redaction coverage looks greatNice job exercising every branch of the string and email redaction logic (including the malformed email fallback). The table-driven layout keeps the intent clear and maintainable.
charts/lfx-v2-auth-service/Chart.yaml (1)
8-9: Chart version bump looks good; confirm release notes and Helm values align.Ensure values.yaml and docs reflect the new Auth0 M2M envs so consumers are not surprised by the minor version bump.
pkg/converters/pointers_test.go (2)
10-64: Solid coverage for StringPtr behavior.Good assertions on pointer non-nil, value equality, and basic aliasing expectations.
66-84: LGTM on mutation semantics test.This confirms no unexpected aliasing of the original value.
pkg/constants/user.go (1)
6-11: Good: criteria constants are clear and scoped.Names and values align with intended search semantics.
pkg/constants/global.go (1)
27-36: Auth0 M2M env keys added correctly.Matches the PR’s Helm values; keep secrets (private key) only in secure stores.
Please confirm values.yaml and deployment manifests set these via Kubernetes secrets, not plain env in ConfigMaps. As per coding guidelines.
pkg/redaction/redaction.go (1)
13-42: Redaction logic is Unicode‑safe and predictable.Policy is conservative and consistent with examples.
go.mod (1)
48-56: Ensure CI/CD uses Go 1.24.5 (or newer)
Update your build agents to match the go directive in go.mod (go 1.24.5), or move to Go 1.25+ to guarantee compatibility with all indirect dependencies.internal/service/message_handler.go (2)
40-46: Option setter LGTM.Consistent with writer option; promotes testability.
60-62: Good: email redaction in logs.Redacts local-part while keeping domain visible. Matches privacy intent.
charts/lfx-v2-auth-service/values.yaml (1)
22-29: Defaults align with mock; good.Keeping USER_REPOSITORY_TYPE=mock by default matches prior decision.

167-173: Authorization header normalization confirmed
httpclient.NewAPIRequest trims the token and prepends "Bearer " if missing, so raw M2M tokens work as expected.

6-12: Add compile‑time check that the mock implements port.UserReader.This guards against interface drift in production code.
Apply this diff:
@@ import ( "context" "errors" "testing" "github.com/linuxfoundation/lfx-v2-auth-service/internal/domain/model" + "github.com/linuxfoundation/lfx-v2-auth-service/internal/domain/port" ) @@ type mockUserReader struct { getUserFunc func(ctx context.Context, user *model.User) (*model.User, error) searchUserFunc func(ctx context.Context, user *model.User, criteria string) (*model.User, error) } +// Ensure mockUserReader implements port.UserReader. +var _ port.UserReader = (*mockUserReader)(nil)Also applies to: 19-21
276-278: Prefer canonical compile‑time interface assertion.Use assignment form to enforce conformance at compile time without conversions.
Apply this diff:
- // Verify interface implementation - var _ = UserServiceReader(orchestrator) + // Verify interface implementation (compile-time) + var _ UserServiceReader = orchestrator
289-307: Avoid asserting unexported concrete types in tests; verify behavior instead.Asserting on internal type couples tests to implementation. Check that the option wires the dependency by observing behavior.

34-36: Run tests in parallel where safe.Mark top‑level tests as parallel to speed up CI. These tests don’t share mutable global state.

59-66: Use t.Fatalf instead of t.Error+return for fatal subtest failures.Simplifies flow and guarantees early exit on invariant violations.
Apply this diff (pattern applies similarly in other subtests):
- if err != nil { - t.Errorf("GetUser() unexpected error: %v", err) - return - } - if result == nil { - t.Error("GetUser() returned nil result") - return - } + if err != nil { + t.Fatalf("GetUser() unexpected error: %v", err) + } + if result == nil { + t.Fatalf("GetUser() returned nil result") + } @@ - if err != nil { - t.Errorf("SearchUser() unexpected error: %v", err) - return - } - if result == nil { - t.Error("SearchUser() returned nil result") - return - } + if err != nil { + t.Fatalf("SearchUser() unexpected error: %v", err) + } + if result == nil { + t.Fatalf("SearchUser() returned nil result") + }Also applies to: 161-168
280-287: Consider adding a test for nil userReader behavior (no options).If orchestrator methods are called without a configured userReader, define expected behavior (error vs. panic) and assert it. This prevents regressions.
Would you like me to draft a subtest that asserts a non‑panic error for GetUser/SearchUser when constructed with no options?

Timestamp: 2025-09-22T14:09:00.504Z
Learning: In the LFX v2 Auth Service, mauriciozanettisalomao prefers explicit failure over silent fallbacks when Auth0 configuration (AUTH0_TENANT, AUTH0_DOMAIN) is incomplete. The service should continue with the Auth0 implementation and fail later during actual connection attempts rather than falling back to mock behavior, as this provides clearer debugging context and avoids masking configuration issues.

78-79: Docstring: tighten wording for clarity and accuracy.Consider a clearer Go doc comment.
-// Call makes an HTTP call with a configured data +// Call executes the configured HTTP request using the provided context.
26-34: Unused Endpoint field and option — remove or implement.Endpoint and WithEndpoint are never used in Call; only URL is validated/used. This creates confusion.
- Option A: Remove Endpoint and WithEndpoint until needed.

john.doeAlso applies to: 65-68
69-75: Align error reply format with service behavior.Elsewhere you document errors as structured replies with success:false. Make this section consistent.
**Error Reply:** -```json -{ - "error": "user not found" -} -``` +```json +{ + "success": false, + "error": "user not found" +} +```
194-200: Default repository type description may not match code.README says default is "auth0" when AUTH0_TENANT is set, "mock" otherwise. Current code defaults to "auth0" unconditionally when USER_REPOSITORY_TYPE is empty. See providers.go Lines 86-90.
Would you like me to update the docs after the code fix in providers.go to reflect: default "auth0" only when AUTH0_TENANT is set, "mock" otherwise?
internal/infrastructure/auth0/token.go (3)
69-75: Guard against leeway exceeding token TTL.If ExpiresIn is unexpectedly small, subtracting leeway can backdate expiry and make token invalid.
- Expiry: time.Now().Add(time.Duration(tokenSet.ExpiresIn)*time.Second - leeway), + Expiry: func() time.Time { + d := time.Duration(tokenSet.ExpiresIn) * time.Second + if d > leeway { + return time.Now().Add(d - leeway) + } + return time.Now().Add(d) + }(),
25-31: Unused httpClient field on TokenManager.httpClient is set but not used by TokenManager or consumers. Remove to reduce confusion unless you plan to expose it.
113-121: Avoid exposing raw access tokens via TokenInfo.Returning AccessToken increases accidental leakage risk in logs/tests. Consider omitting or gating behind a debug-only method.

105-109: Avoid logging full request bodies (potential PII).This was raised earlier and deferred; reiterating as a low-friction improvement: log size or a redacted/truncated form.

141-148: Error logging of full response is acceptable here.Per project decision for Auth0 errors, logging full response bodies is fine.

- Updated the message handler orchestrator to directly use user reader and writer instances instead of orchestrators. - Enhanced the QueueSubscriptions function for improved clarity and efficiency. - Added new mock implementations for user service reader to facilitate testing of email to username functionality. - Introduced comprehensive tests for email to username conversion, covering various scenarios including validation and error handling.

159-161: New NATS subject wiring looks good.Routing lfx.auth-service.email_to_username to the message handler aligns with the new feature.
internal/service/message_handler_test.go (4)
47-66: Solid mock reader for targeted behavior.The mockUserServiceReader enables precise control of GetUser/SearchUser for tests. Good isolation.
151-154: Good validation coverage for UpdateUser.Tests assert required metadata and structured error responses. This guards against regressions in validation.
Also applies to: 165-195
301-551: Comprehensive EmailToUsername test matrix.Covers trimming, lowercasing, not-found, service errors, empty username, and complex emails. Matches the contract of returning plain text on success and JSON on error.
553-590: Nil-reader scenario is correctly validated.Ensures a friendly, structured error when userReader is not configured.
internal/service/message_handler.go (1)
59-66: Input normalization and nil-guard look good.Trimming, downcasing, and guarding against a nil reader align with the endpoint’s contract and tests.
…dling - Renamed UserUpdateResponse to UserDataResponse for clarity in message_handler.go. - Improved API call handling in request.go to skip JSON decoding when the response body is empty or not needed, enhancing performance and logging.

Learning: In the LFX v2 Auth Service Auth0 implementation, mauriciozanettisalomao prefers to avoid implementing email search fallbacks when the primary users-by-email endpoint returns zero results. The service should return "user not found" directly rather than attempting secondary search queries, prioritizing implementation simplicity over handling Auth0 eventual consistency edge cases.

Learning: In the LFX v2 Auth Service Auth0 implementation, mauriciozanettisalomao prefers to use backticks for Auth0 query strings and skip double quotes around username values in search queries, using the simpler `users?q=username:%s&search_engine=v3` pattern instead of exact matching with quotes.

Timestamp: 2025-09-22T14:09:00.504Z
Learning: In the LFX v2 Auth Service, mauriciozanettisalomao prefers explicit failure over silent fallbacks when Auth0 configuration (AUTH0_TENANT, AUTH0_DOMAIN) is incomplete. The service should continue with the Auth0 implementation and fail later during actual connection attempts rather than falling back to mock behavior, as this provides clearer debugging context and avoids masking configuration issues.

Learning: In the LFX v2 Auth Service Auth0 implementation, mauriciozanettisalomao has deferred updating the username search pattern from `users?q=identities.user_id:%s&search_engine=v3` to `users?q=username:%s&search_engine=v3` to upcoming PRs, as the username search functionality is not currently being used.

Learning: In the LFX v2 Auth Service, mauriciozanettisalomao has confirmed that the default USER_REPOSITORY_TYPE should remain 'mock', not 'auth0'. The code in cmd/server/service/providers.go line 89 should default to constants.UserRepositoryTypeMock when the environment variable is not set, contradicting the previous plan to change the default to auth0.

Timestamp: 2025-09-25T23:42:49.762Z
Learning: In the LFX v2 Auth Service, mauriciozanettisalomao expects the NewUserReaderWriter constructor to fail when USER_REPOSITORY_TYPE is 'auth0' but required Auth0 M2M environment variables (AUTH0_CLIENT_ID, AUTH0_PRIVATE_BASE64_KEY, AUTH0_AUDIENCE) are missing. This fail-fast approach is intentional to ensure complete Auth0 configuration rather than allowing degraded functionality.

Timestamp: 2025-09-19T17:05:21.230Z
Learning: The mock user implementation in internal/infrastructure/mock/user.go uses fantasy/fake user data (like "zephyr.stormwind", "aurora.moonbeam") for development and testing purposes, so logging full user objects is acceptable in this context.

Overview
This pull request introduces significant improvements and new features to the Auth0 integration for the LFX V2 Auth Service, focusing on enhanced user search capabilities, support for Auth0 Machine-to-Machine (M2M) authentication, and improved configuration and dependency management. The changes add support for searching users by email or username, refactor the Auth0 user reader/writer implementation, and introduce a new token manager for secure M2M authentication. Additionally, the Helm chart and configuration files have been updated to support these new features.
