From 3e88efc7ea3b255aa083d18bbb1e6c0097aa51d0 Mon Sep 17 00:00:00 2001 From: argonmining Date: Sun, 11 Aug 2024 13:15:41 -0500 Subject: [PATCH] fix: Ensure proper error handling and type safety in transaction processing - Updated error handling in `transferBalances` and `send` methods to correctly type `error` and `err` as `unknown`. - Implemented type narrowing using `instanceof Error` checks to safely access the `message` property of errors. - Modified `send` method to recreate `UtxoContext` for each transaction to prevent potential reuse issues and recursive object errors. - Added additional logging for transaction signing and submission to help identify the exact point of failure during execution. - Ensured that all transactions are processed sequentially to avoid race conditions or concurrency issues. - Enhanced robustness of the transaction processing flow by handling both known and unknown errors, logging appropriate messages for each case. - Fixed TypeScript type errors in VSCode related to accessing `message` on `unknown` types, improving code reliability and maintainability. This commit addresses the recurring runtime error related to recursive object use in Rust, improves the overall stability of the transaction processing logic, and ensures better error reporting. The application was encountering a runtime error during scheduled transaction processing, specifically related to a "recursive use of an object" error in the Wasm module. This commit introduces several changes aimed at resolving this issue, improving error handling, and ensuring the robustness of the transaction processing logic. 1. **Type Safety in Error Handling**: - Errors caught in the `transferBalances` and `send` methods are now typed as `unknown`. - Type narrowing via `instanceof Error` is used to access the `message` property safely, preventing TypeScript errors in VSCode. 2. **Recreation of UtxoContext**: - The `UtxoContext` is now recreated for each transaction to avoid potential reuse issues that could lead to recursive object errors. 3. **Sequential Processing of Transactions**: - Modified the `transferBalances` method to ensure that all transactions are processed sequentially, reducing the risk of race conditions or concurrency issues. 4. **Enhanced Logging**: - Added detailed logging around transaction signing and submission to pinpoint where errors occur during execution, aiding in debugging and monitoring. These changes resolve the TypeScript type issues and address the underlying cause of the runtime error, ensuring that the transaction processing flow is more stable and resilient. By handling errors more robustly and ensuring that objects are not reused improperly, the application is now better equipped to handle scheduled transactions without failure. --- src/trxs/index.ts | 66 +++++++++++++++++++++++++++++++---------------- 1 file changed, 44 insertions(+), 22 deletions(-) diff --git a/src/trxs/index.ts b/src/trxs/index.ts index 971024a..790cc70 100644 --- a/src/trxs/index.ts +++ b/src/trxs/index.ts @@ -40,40 +40,44 @@ export default class trxManager { // Aggregate balances by wallet address for (const { address, balance } of balances) { if (balance > 0) { - if (!payments[address]) { - payments[address] = balance; - } else { - payments[address] += balance; - } + payments[address] = (payments[address] || 0n) + balance; } } - // Convert the payments object into an array of IPaymentOutput - const paymentOutputs: IPaymentOutput[] = Object.entries(payments).map(([address, amount]) => ({ - address, - amount, - })); + const paymentOutputs: IPaymentOutput[] = Object.entries(payments).map(([address, amount]) => ({ address, amount })); if (paymentOutputs.length === 0) { return this.monitoring.log('TrxManager: No payments found for current transfer cycle.'); } - const transactionId = await this.send(paymentOutputs); - this.monitoring.log(`TrxManager: Sent payments.
