PRIVATE TO PUBLIC BESU TESTER

Project to test the Besu bug founded in 27.1.4 when a private contract calls to a public contract that also calls to another public contract.

Besu test network

In order to simplify testing, a besu network is integrated with 3 nodes: 1 validator and two nodes with privacy and tessera.

In order to use this facility, it is necessary to have docker and docker-compose installed on the machine.

Starting besu

To start the network and configure the privacy group:

$ npm run start-besu

Throubleshooting

If during first start-besu, during the creation of the privacy group it fails with:

(node:46296) UnhandledPromiseRejectionWarning: Error: Returned error: Onchain Privacy group does not exist.

Run in the console:

$ npm run stop-besu
$ npm run start-besu

Stopping besu

Para parar la red y borrar los volúmenes docker:

$ npm run stop-besu

Reproducing the issue

With the Besu network started, run npm test from the console to reproduce the described problem, and the result will look like this:

$ npm test

> [email protected] test
> npx truffle exec scripts/private_public_test.js --network adminAro

Using network 'adminAro'.

On public space:
  * Deploying StoreDataContract
  * Deploying GenericContract on public space using StoreDataContract

 On private space:
  * Deploying PrivateContract using GenericContract's of public space
Waiting for transaction to be mined ...
  * Call to getPublicContractData
  * Call to getPublicStoreContractData. It fails


Result of the test: 

{
  "public": {
    "storeDataContract": {
      "address": "0x32C6E44A0cF079263d7bAE8794D1A475797c1e23",

    },

    }
  },

    "blockNumber": "0xcb5e"
  },
  "tests": {
    "Call to getPublicContractData": {
      "0": "123",
      "__length__": 1
    },
    "Call to getPublicStoreContractData. It fails": "Returned error: Invalid params"
  }
}

When a contract deployed in the private space calls another contract deployed in the public space that also calls another public contract, it fails with a result of 0x.
