Tx-Replayer

A lightweight transaction replay tool for debugging and analyzing transactions, as well as measuring resource usage during transaction verification with profiler tools such as heaptrack and samply.

Disclaimer: Use this tool only on a copy of your database. Running it on a live database may cause data loss or corruption.

Usage

Build

% make

To replay the whole transaction verification step.

% ./tx-replayer --database-path [DATABASE_PATH] --tx-hash [TX_HASH]

To replay only the Zk proof verification part.

% ./tx-replayer --zkp --database-path [DATABASE_PATH] --tx-hash [TX_HASH]

To replay only the wasm Runtime verification part.

% ./tx-replayer --wasm --database-path [DATABASE_PATH] --tx-hash [TX_HASH]

To replay only the signature verification part.

% ./tx-replayer --sig --database-path [DATABASE_PATH] --tx-hash [TX_HASH]

You can run samply to see the CPU usage of the transaction verification.

% samply record ./tx-replayer --database-path [DATABASE_PATH] --tx-hash [TX_HASH]
