`unlimitedContractSize` option is not applied to calls to `eth_estimateGas`

Reporduction:

Clone https://github.com/anishnaik/ganache-bug and checkout the bug branch.

The testing script is called deploy.js.

Ganache@7.3.2 Terminal 1

npm uninstall -g ganache-cli (if applicable)
npm install -g ganache
ganache -d -l 100000000000 --chain.allowUnlimitedContractSize --miner.callGasLimit 0x1fffffffffffff

Terminal 2

npm install
npx hardhat test deploy.js

This should fail with the following error:

  Deploy contracts for Echidna
    1) Deploy


  0 passing (110ms)
  1 failing

  1) Deploy contracts for Echidna
       Deploy:
     ProviderError: VM Exception while processing transaction: out of gas
      at HttpProvider.request (node_modules/hardhat/src/internal/core/providers/http.ts:78:19)
      at GanacheGasMultiplierProvider._getMultipliedGasEstimation (node_modules/hardhat/src/internal/core/providers/gas-providers.ts:72:59)

You can try to set a gasLimit for the deploy() call and if it is large enough, the test will pass.

ganache-cli@6.12.2 Terminal 1

npm uninstall -g ganache
npm install -g ganache-cli
ganache-cli -d --gasLimit 100000000000 --allowUnlimitedContractSize

Terminal 2

npx hardhat test deploy.js

This test should pass

This could also be a dependency issue in the hardhat environment?

@anishnaik I’ve found the issue. callGasLimit is working in eth_estimateGas, but allowUnlimitedContractSize is not.

estimateGas makes a copy of the VM before running the transaction in order to estimate it. The allowUnlimitedContractSize property is not copied, as you can see here:

There is currently no work around but I hope to get a fix in for this very soon.

There is no timeline; we are working now to improve stability.
