Avoid unnecessary syncs in push-only sync mode #188
Conversation
WalkthroughThe recent updates to the Yorkie project primarily focus on enhancing synchronization functionality and testing. New methods and imports have been added to facilitate better real-time synchronization and to test these features more effectively. Specifically, a new test method was introduced to avoid unnecessary syncs, and a method was added to determine the need for real-time synchronization. Additionally, a timeout constant was standardized across tests. Changes

12-18: The implementation ofneedRealTimeSyncmethod correctly handles the sync logic based onsyncMode. This should effectively reduce unnecessary sync operations in push-only mode.yorkie/src/androidTest/kotlin/dev/yorkie/document/json/JsonTreeConcurrencyTest.kt (1)
5-5: Replacing hardcoded timeout values withGENERAL_TIMEOUTis a good practice for maintainability and ensures consistency across tests.yorkie/src/main/kotlin/dev/yorkie/core/Client.kt (1)
185-185: The modification to useneedRealTimeSyncfrom theAttachmentclass centralizes the sync logic, enhancing maintainability and reducing code duplication. Ensure this change integrates well with the rest of the system.Verification successful
The
needRealTimeSyncmethod in theAttachmentclass is correctly implemented and checks thesyncModeto determine if real-time synchronization is needed. The integration of this method in thefilterRealTimeSyncNeededfunction centralizes the sync logic, enhancing maintainability and reducing code duplication.
Attachment.kt:internal data class Attachment( val document: Document, val documentID: String, val syncMode: Client.SyncMode = Client.SyncMode.Realtime, val remoteChangeEventReceived: Boolean = false, ) { fun needRealTimeSync(): Boolean { return if (syncMode == Client.SyncMode.RealtimePushOnly) { document.hasLocalChanges } else { syncMode.needRealTimeSync } } }This change is well-implemented and should integrate seamlessly with the rest of the system.

14-16: Added imports forJsonObjectandJsonText.These imports are necessary for the new test method
test_avoid_unnecessary_syncs_in_push_onlyto function correctly.
703-771: New test methodtest_avoid_unecessary_syncs_in_push_onlyadded.This test method is crucial for ensuring that unnecessary synchronizations are avoided in push-only sync mode. It effectively simulates the scenario and checks the synchronization status and content of the documents to ensure they are as expected. The use of
withTimeoutensures that the test does not hang indefinitely, which is a good practice for asynchronous tests.

how about moving all the logic to Attachment.needRealTimeSync?

that's much better, I think. done in 6b7ebaf
