From a31235a98614dff95ee972ca480263d4b3e3ae3c Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 23 Jun 2025 03:50:02 +0000 Subject: [PATCH] Implement core improvements Batch 1 This commit includes the following improvements: 1. **DB: Ensure Chronological Message Ordering** * Modified `MessageDao.loadMessages` to include `ORDER BY created_at ASC`, ensuring messages are fetched in the correct order. 2. **DB: Add Index for Message Loading** * Added an `@Index` for `(chat_id, created_at)` to the `Message` entity to optimize query performance for loading ordered messages. 3. **UI: Stable Keys for ChatScreen LazyColumn** * Provided stable keys (`message.id`, timestamps) to `LazyColumn` items in `ChatScreen.kt` to improve Compose UI performance and state handling. 4. **Perf: Cache API Client Instances** * Implemented caching for `OpenAI` and `GenerativeModel` clients in `ChatRepositoryImpl`. Clients are now reused based on configuration (token, API URL, model name), reducing overhead from redundant instantiation. 5. **Test: Initial Unit Tests for Client Caching** * Created `ChatRepositoryImplTest.kt` with unit tests verifying the API client caching logic using reflection to inspect cache state. * Made internal config data classes in `ChatRepositoryImpl` accessible for testing. --- .../gptmobile/data/database/dao/MessageDao.kt | 2 +- .../gptmobile/data/database/entity/Message.kt | 4 +- .../data/repository/ChatRepositoryImpl.kt | 78 +++-- .../presentation/ui/chat/ChatScreen.kt | 23 +- .../data/repository/ChatRepositoryImplTest.kt | 275 ++++++++++++++++++ 5 files changed, 348 insertions(+), 34 deletions(-) create mode 100644 app/src/test/kotlin/dev/chungjungsoo/gptmobile/data/repository/ChatRepositoryImplTest.kt diff --git a/app/src/main/kotlin/dev/chungjungsoo/gptmobile/data/database/dao/MessageDao.kt b/app/src/main/kotlin/dev/chungjungsoo/gptmobile/data/database/dao/MessageDao.kt index e8cd32d9..22881205 100644 --- a/app/src/main/kotlin/dev/chungjungsoo/gptmobile/data/database/dao/MessageDao.kt +++ b/app/src/main/kotlin/dev/chungjungsoo/gptmobile/data/database/dao/MessageDao.kt @@ -10,7 +10,7 @@ import dev.chungjungsoo.gptmobile.data.database.entity.Message @Dao interface MessageDao { -
