+ +After successful rollback: + +1. **Verification** + - [ ] Test message loading (regular chat) + - [ ] Test agent sessions + - [ ] Verify file attachments work + - [ ] Check message editing/deletion + - [ ] Confirm no data loss + +2. **Investigation** + - [ ] Analyze performance metrics + - [ ] Review error logs + - [ ] Identify root cause + - [ ] Create bug report + +3. **Planning** + - [ ]

**Manual Validation** + - Create new chat conversation + - Send messages with attachments + - Edit existing messages + - Delete messages + - Start agent session + - Load historical messages + +3.

- Status: ✅ Integrated - - Used in updateMessageAndBlocksThunk - -## Not Yet Integrated - -### Functions Available but Not Used -These V2 functions exist but haven't been integrated yet as their usage patterns are different: - -- **getRawTopicV2** - Available but not directly replacing db.topics.get() calls -- **getTopicV2** - Available but not directly replacing db.topics.get() calls -- **persistExchangeV2** - Available for future use with message exchanges - -### Complex Operations Still Using Original Implementation -These operations involve complex transactions and topic management that would need careful refactoring: - -1. **Topic message list updates** (db.topics.update with messages array) - - Used after delete operations - - Used in resendMessageThunk - - Used in regenerateAssistantMessageThunk - -2. **Transaction-based operations** - - cloneMessagesToNewTopicThunk (partial integration) - - initiateTranslationThunk - - removeBlocksThunk - -## Testing Checklist - -### High Priority (Core Operations) -- [x] Load messages for regular topic -- [x] Load messages for agent session -- [ ] Send message in regular chat -- [ ] Send message in agent session -- [ ] Delete single message -- [ ] Delete message group -- [ ] Clear all messages - -### Medium Priority (Edit Operations) -- [ ] Update message content -- [ ] Update message blocks -- [ ] Update translation blocks -- [ ] File reference counting - -### Low Priority (Advanced Features) -- [ ] Clone messages to new topic -- [ ] Resend messages -- [ ] Regenerate assistant messages -- [ ] Multi-model responses - -## Next Steps - -1. **Test Current Integrations** - - Enable feature flag and test all integrated operations - - Monitor for any errors or performance issues - - Verify data consistency - -2. **Phase 3 Consideration** - - Consider refactoring complex topic update operations - - Evaluate if persistExchangeV2 should be used for user+assistant pairs - - Plan migration of remaining db.topics operations - -3. **Performance Monitoring** - - Compare load times between original and V2 - - Check memory usage with large message histories - - Verify agent session performance - -## Rollback Instructions -If issues occur, disable the feature flag immediately: -```javascript -localStorage.setItem('featureFlags', JSON.stringify({ USE_UNIFIED_DB_SERVICE: false })) -location.reload() -``` - -## Notes -- All V2 implementations maintain backward compatibility -- Agent session operations (IPC-based) are handled transparently -- File operations only apply to Dexie storage, not agent sessions -- Feature flag allows gradual rollout and A/B testing \ No newline at end of file diff --git a/src/renderer/src/services/db/ROLLBACK.md b/src/renderer/src/services/db/ROLLBACK.md deleted file mode 100644 index 377b24626d..0000000000 --- a/src/renderer/src/services/db/ROLLBACK.md +++ /dev/null @@ -1,206 +0,0 @@ -# Rollback Strategy for Unified Database Service Migration -

Revert to previous commit: - ```bash - git revert HEAD # If just deployed - # or - git checkout - ``` -2. Rebuild and deploy: - ```bash - yarn build:check - yarn build - ``` -3.
