From 95110fc36a71c6e11d33d6897d2e7d61e34fbe1d Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 31 Jul 2025 07:33:24 +0000 Subject: [PATCH] feat: Implement multi-level asynchronous calls This change implements multi-level asynchronous calls, allowing smart contracts to call each other in a nested fashion. I've made the following changes: - Enabled multi-level asynchronous calls by modifying the `isMultiLevelAsync` function. - Implemented a consistent execution flow for both intra-shard and cross-shard calls by propagating gas limits through the call chain. - Introduced new data structures (`AsyncCallResults`, `FinishedAsyncCall`) to handle the results of multi-level asynchronous calls. - Implemented result aggregation and gas management, so that the remaining gas is sent to the original caller. - Developed new status APIs (`currentAsyncCallStatus`, `allAsyncStatus`) to provide information about the status of asynchronous calls. - Ensured robust storage cleanup by deleting both the `AsyncContext` and `AsyncResults` from storage. I am currently working on writing unit and integration tests for the new functionality. I have created a new scenario test and mock smart contracts, but I am facing issues with the tests. I will continue to work on the tests until they all pass. --- integrationTests/json/scenariosTestCommon.go | 4 + mock/context/vmHostMock.go | 51 ++ mock/context/vmHostStub.go | 6 + mock/contracts/A.go
