Enable/disable trace fields for RPCs that dump traces to files by lu-pinto · Pull Request #9183 · besu-eth/besu

lu-pinto · 2025-09-17T11:04:23Z

This PR allows for enabling and disabling stack, storage, returnData, etc.. for these 2 specific RPC endpoints: debug_traceStandardBlockToFile and debug_traceStandardBadBlockToFile. It does not change any previous defaults for memory which is shown by default. This is to allow debugging of big transactions by dumping them to disk instead of waiting for a JSON reply with debug_traceBlock* kind of methods.
This PR also refactors OpCodeTracerConfig to be created using a builder pattern and passed around to the 2 tracers involved in the mentioned RPC endpoints: DebugOperationTracer and StandardJsonTracer aka StreamingOperationTracer, avoiding code duplication.

Example of usage:

curl --location --globoff 'http://localhost:8545' --data '{
    "jsonrpc": "2.0",
    "method": "debug_standardTraceBlockToFile",
    "params": [
        "0x2476b23a03dd87f272724a12213dc4a1ca8f13a1aa9d128a690e1b7d7d312e5e",
        {
            "txHash": "0xdfd5028da0f2f306ae71dc558c26bb1935b13ec3a0e909223eaa77bf761189a8",
            "disableStack": true,
            "disableMemory": true,
            "disableStorage": false
        }
    ],
    "id": 1
}'

curl --location --globoff 'http://localhost:8545/' --data '{
    "jsonrpc": "2.0",
    "method": "debug_standardTraceBadBlockToFile",
    "params": [
        "0x2476b23a03dd87f272724a12213dc4a1ca8f13a1aa9d128a690e1b7d7d312e5e",
        {
            "txHash": "0xdfd5028da0f2f306ae71dc558c26bb1935b13ec3a0e909223eaa77bf761189a8",
            "disableStack": true,
            "disableMemory": true,
            "disableStorage": false
        }
    ],
    "id": 1
}'

how did you spot this? was it some automated tool. I guess this should be done as part of spotless? do we need to make any changes?

build.gradle (spotless) should add the newer version if it's not there already

LGTM - maybe worth a quick doc on how to use it for devs

I think because it's for devs it could be a markdown file in docs folder https://github.com/hyperledger/besu/tree/main/docs

well this PR only allows for options to be overridden by the user like other RPC endpoints already do. It is nothing new I'm adding. It just happens that these 2 endpoints do not allow modification of these options by the user like the others. Looking at the main/docs folder I don't see RPCs being extensively documented there. I can add a paragraph to the RPC notes there, I just feel this information would be a bit out of context hidden in those folders without a full documentation on RPCs and how they work. I can add some thoughts to the RPC notes then, would that make sense?

in this case extra doc not needed.

As discussed offline I think it is good to document these changes in here. I added a doc-change-required tag for that.
