app/src/main/java/me/capcom/smsgateway/data/AppDatabase.kt (1)
61-61: Consider implementing manual migration as fallback.While auto migration is configured, having a commented placeholder for
MIGRATION_14_15suggests awareness of potential complexity. Consider implementing the manual migration as a safety measure, especially for production environments.app/schemas/me.capcom.smsgateway.data.AppDatabase/15.json (1)
104-112: Single-columncreatedAtindex is probably redundant
index_Message_createdAtduplicates the leading column ofindex_Message_state_createdAt.
SQLite can satisfy a search on justcreatedAtby using the composite index, so the extra index costs ~1 MiB per million rows without improving query plans.- { - "name": "index_Message_createdAt", - "unique": false, - "columnNames": [ - "createdAt" - ], - "orders": [], - "createSql": "CREATE INDEX IF NOT EXISTS `index_Message_createdAt` ON `${TABLE_NAME}` (`createdAt`)" - },app/src/main/java/me/capcom/smsgateway/modules/localserver/routes/MessagesRoutes.kt (1)
46-97: Well-implemented GET endpoint with good validation and error handling.The new GET endpoint provides comprehensive functionality with:
- Proper parameter parsing and validation
- Date range validation (start <= end)
- Appropriate error handling with meaningful HTTP status codes
- Pagination support with X-Total-Count header
- Clean exception handling
Consider adding a maximum limit validation to prevent potential performance issues:
val limit = call.request.queryParameters["limit"]?.toIntOrNull() ?: 50 +val validatedLimit = limit.coerceAtMost(1000) // Prevent excessive queries

app/src/main/java/me/capcom/smsgateway/data/Migrations.kt (1)
86-86: LGTM: Cosmetic formatting improvement.The addition of a newline at the end of the file follows good formatting practices.
app/src/main/java/me/capcom/smsgateway/modules/localserver/domain/GetMessagesResponse.kt (1)
1-3: LGTM: Clean type alias definition.The type alias provides clear semantic meaning for message list responses and improves API readability.
app/src/main/java/me/capcom/smsgateway/modules/localserver/domain/PostMessageResponse.kt (1)
3-3: LGTM: Good consolidation of response types.Replacing the explicit data class with a type alias to
Messageeliminates duplication and ensures consistency across the domain model.app/src/main/java/me/capcom/smsgateway/data/entities/Message.kt (1)
16-20: Verify composite index usage in DAO queries
- Detected one DAO method in
app/src/main/java/me/capcom/smsgateway/data/dao/MessagesDao.kt:48
@query("… WHERE (:state IS NULL OR state = :state) AND createdAt BETWEEN … ORDER BY createdAt DESC …")
– This will leverage the[state, createdAt]composite index.- No DAO queries found filtering by
stateand ordering byprocessedAt
– Please confirm any queries that should use the[state, processedAt]index are present.- Double-check whether the standalone
createdAtindex is still required for queries without astatefilter.app/src/main/java/me/capcom/smsgateway/data/AppDatabase.kt (2)
27-27: Database version increment looks correct.The version bump to 15 aligns with the schema changes described in the PR.
42-42: AutoMigration v14→v15 only modifies indices on the Message table
All other tables, columns, foreign keys and defaults remain unchanged. Specifically, v14’sindex_Message_stateandindex_Message_processedAtare dropped and replaced with two composite indices (index_Message_state_createdAt,index_Message_state_processedAt). Room’s auto-migration fully supports adding and removing indices, so no manual migration is required.app/src/test/java/me/capcom/smsgateway/modules/messages/MessagesServiceTest.kt (2)
26-52: Good basic test for object creation.This test provides actual value by verifying
MessageWithRecipientsconstruction and basic property access. The test covers different recipient states which is useful.Consider enhancing this test to cover edge cases like empty recipient lists, null values, or invalid states.
26-52: LGTM - Good functional test for domain object construction.The test properly verifies the creation and properties of
MessageWithRecipientsobjects, including message attributes, recipient count, and processing states. This provides good coverage for the domain model construction.app/src/main/java/me/capcom/smsgateway/modules/messages/MessagesService.kt (6)
24-24: LGTM!The import is necessary for the new methods and correctly placed.
58-58: Excellent code organization with regions.The addition of region markers improves readability and maintainability of this large service class. The logical grouping (Health, Lifecycle, Send, Read) makes sense.
Also applies to: 76-76, 78-78, 88-88, 90-90, 103-103, 105-105, 143-143
126-130: Well-designed count method with proper delegation.The method signature is clean with appropriate parameters for filtering. The nullable
stateparameter allows for flexible filtering, and the delegation to DAO is correct.
132-142: Consistent and well-designed select method with pagination.The method follows the same filtering pattern as
countMessageswhile adding pagination support. Parameter order is logical and the DAO delegation is appropriate.
24-24: LGTM - Appropriate import addition.The
EntitySourceimport is correctly added to support the new query methods.
58-143: LGTM - Well-organized code with clear regional separation.The addition of region comments (
Health,Lifecycle,Send,Read) significantly improves code readability and logical organization. The newcountMessagesandselectMessagesmethods provide a clean service layer interface that appropriately delegates to the DAO layer.app/src/main/java/me/capcom/smsgateway/modules/localserver/domain/Message.kt (2)
6-20: Well-designed domain model with good encapsulation.The
Messageclass has a clean structure with appropriate property types. The nestedRecipientdata class is well-designed, and thestatesmap provides useful audit trail functionality.Consider if any property validations are needed (e.g., non-empty id, valid phone numbers in recipients).
6-20: LGTM - Well-designed domain model.The
Messageclass provides a comprehensive domain model with appropriate properties for tracking message state, recipients, and historical state transitions. The nestedRecipientdata class is well-structured, and the use ofMap<ProcessingState, Date>for state history provides good auditability.app/src/main/java/me/capcom/smsgateway/data/dao/MessagesDao.kt (7)
15-16: LGTM!The new imports are necessary for the added DAO methods and properly placed.
20-20: Good organization with region markers.The region grouping improves code organization and makes the DAO methods easier to navigate.
Also applies to: 57-57
38-42: Well-implemented count query with proper nullable handling.The SQL query correctly handles the nullable state parameter and uses proper parameter binding. The
BETWEENoperator for date range is inclusive on both ends - ensure this matches the intended behavior.
44-56: Excellent implementation of paginated select with proper transaction handling.The method correctly uses
@Transactionfor consistency, includes proper ordering (most recent first), and implements pagination correctly. Therowidinclusion is necessary for Room's relationship loading.
15-16: LGTM - Appropriate imports for new functionality.The imports for
EntitySourceandProcessingStateare correctly added to support the new query methods.
24-24: Good bug fix - Using processedAt instead of createdAt.The change from
createdAttoprocessedAtin thecountFailedFromquery is correct, as it should count failed messages based on when they were processed, not when they were created.
38-56: LGTM - Well-designed query methods with proper nullability handling.The new
countandselectmethods are well-implemented with:
- Proper SQL nullability handling using
(:state IS NULL OR state = :state)- Appropriate use of
@Transactionannotation for the select method- Consistent ordering by
createdAt DESC- Good parameter naming and documentation
app/src/main/java/me/capcom/smsgateway/modules/localserver/routes/MessagesRoutes.kt (9)
13-13: LGTM!The new imports are necessary for the added functionality and properly organized.
Also applies to: 17-17, 19-19
46-97: Comprehensive and well-implemented GET endpoint with proper error handling.The endpoint provides excellent filtering and pagination capabilities with proper parameter validation, error handling, and response formatting. The date validation and total count header are particularly good touches.
Consider adding parameter validation for negative limit/offset values to prevent potential issues.
244-245: Good refactoring to use consistent domain model.The changes properly integrate with the new domain model by using the
Message.Recipientclass andtoDomainmapping function. SettingisHashed = falseappears to be a reasonable default.Also applies to: 247-252, 272-272
292-309: Clean domain mapping function with proper property transformation.The extension function provides excellent encapsulation of entity-to-domain mapping logic. The states transformation correctly converts timestamps to Date objects.
The hardcoded
isHashed = falsesuggests this feature is planned but not yet implemented - consider adding a TODO comment if this is temporary.
13-19: LGTM - Appropriate imports for new functionality.The imports for
MessageWithRecipients,DateTimeParser, andGetMessageResponseare correctly added to support the new endpoint and domain mapping functionality.
244-245: LGTM - Consistent domain model usage.The addition of
isHashed = falseand proper positioning ofisEncryptedaligns with the new domain model structure.
247-252: LGTM - Updated to use domain Recipient class.The change to use
me.capcom.smsgateway.modules.localserver.domain.Message.Recipientis consistent with the new domain model design.
272-272: LGTM - Consistent use of domain mapping.The change to use the
toDomainextension function provides consistent mapping between database entities and domain models.
292-309: Device ID is safely initialized before route usageThe
toDomainextension cleanly mapsMessageWithRecipientsto the domainMessage, handling recipients and state history.
TheLocalServerService.startmethod assigns a generateddeviceIdif it’s null before callingWebService.start, so by the time anyMessagesRouteshandler invokesrequireNotNull(settings.deviceId), it’s guaranteed to be non-null.app/schemas/me.capcom.smsgateway.data.AppDatabase/15.json (1)
4-5: Migration from v14 → v15 is marked but not implementedThe schema declares database version 15. Unless a full auto-migration is registered and verified at runtime, Room will throw an
IllegalStateExceptionwhen the application starts.
Double-check thatAppDatabase.autoMigrations(or a manualMigration(14, 15)) is in place and covered by instrumentation tests before shipping.

94-106: Enum added forstatefilter – previous feedback fully addressedThe
statequery parameter now exposes an explicit enum with all five allowed values, aligning the contract withMessageStatus.stateand enabling strict validation in generated clients. Nicely done.
119-126: Add a lower-bound tolimitto avoid zero-item pages

160-167: Cap the array size in the 200-response schemaStatic-analysis (CKV_OPENAPI_21) warns that unbounded arrays may lead to runaway payloads.
The endpoint already controls throughput via thelimitparameter, so mirror that in the schema:- "type": "array", + "type": "array", + "maxItems": 100, "items": { "$ref": "#/components/schemas/MessageStatus" }This keeps the OpenAPI contract consistent with runtime behaviour and silences the linter.
765-789: Defaults on read-only fields are redundant
state,isHashed, andisEncryptedare markedreadOnly: true, so their defaults are never applied by client input.
Removing thedefaultkeywords (or relocating them toexample) tightens the schema and avoids confusion for code-gen tools that warn about inert defaults.

94-107: Enum added – previous concern resolvedThe
statequery parameter is now restricted to the same five values defined forMessageStatus.state, closing the validation gap flagged earlier. Nice cleanup.
119-127:limitlacks a lower boundYou capped the upper bound at 100 but omitted a
minimum, so callers may requestlimit=0and receive an empty list (or worse, undefined driver behaviour). Align with common practice and require at least one item:"schema": { "type": "integer", "maximum": 100, + "minimum": 1, "default": 50 }
