`--miner.callGasLimit` implementation is wrong

The purpose of the miner.callGasLimit option is to set a cap on gas that is used in an eth_call/eth_estimateGas RPC call (as in geth’s --rpc.gascap option). The purpose of this option is to prevent a DOS attack wherein a contract is uploaded with an infinite loop and eth_call is used on that contract, causing miners to work very very hard.

Currently, it’s used as a default gas limit for a transaction that is calling eth_call/eth_estimateGas.

Fix it!

Thanks for the additional information, we’ll look into it! I’ve opened https://github.com/trufflesuite/ganache/pull/3322 to correct the documentation issue.

Is there an update on this? I believe this is causing differential behavior b/w the latest release of ganache and the deprecated ganache-cli@6.12.2

eth_estimateGas is throwing an out-of-gas error when extremely large contracts are being deployed with the latest release (v7.3.2). This does not occur with the old ganache-cli. My working assumption is that it is because miner.callGasLimit is not being correctly used.

To reproduce, you can try to deploy ComptrollerHarness using hardhat (instead of saddle) + ganache.

This is the ganache-cli command: ganache-cli --deterministic --gasLimit 10000000000000000 --allowUnlimitedContractSize

This is the ganache command: ganache --deterministic --gasLimit 10000000000000000 --chain.allowUnlimitedContractSize

The ganache command returns the following error in hardhat:

     ProviderError: VM Exception while processing transaction: out of gas
      at HttpProvider.request (node_modules/hardhat/src/internal/core/providers/http.ts:78:19)

 {'message': 'VM Exception while processing transaction: out of gas', 'stack': 'RuntimeError: VM Exception while processing transaction: out of gas\n    at exactimate (/usr/local/lib/node_modules/ganache/dist/node/1.js:2:113332)', 'code': -32000, 'name': 'RuntimeError', 'data': {'hash': None, 'programCounter': 97, 'result': '0x', 'reason': None, 'message': 'out of gas'}}

The current working solution is to specify a gasLimit directly to the call for await ComptrollerHarness.deploy({gasLimit: some_limit}); however, this seems to hint at a larger problem.
