4 years ago After updating the contracts on this branch and updating the transpiler, I now cannot even get the contracts to compile. Make sure you're using Node 10 (Node 12 can't install all dependencies), and use yarn --ignore-engines to install everything. Then try and compile with the command:
NODE_OPTIONS="--max-old-space-size=4096" yarn truffle compile --config ./truffle-config-ovm.js
we get an error in ColonyNetwork:
[Could not find CODECOPYed constant in transpiled deployed bytecode for PC 0x3c63. We originally recorded the constant as 0x4035866040518263ffffffff1660e01b815260040162002a63919062003f02565b60, but it does not exist in the post-transpiledwhich is then followed with the transpiled bytecode. There are a lot more errors after that, but my best guess is that this is a case of some of the tagging going wrong? The subsequent errors talk about opcodes that don't exist, so I guess they shouldn't be being processed as opcodes, but as constants? I really don't know though...
I've created an
ovmbranch where I've been trying to apply the OVM truffle guide.To try and run our tests with the OVM, use the command
yarn truffle test ./test/contracts-network/colony.js --config truffle-config-ovm.jsChanges so far:
selfdestructcalls - not supported, and will not ever be fully supported (see https://github.com/ethereum-optimism/optimism-monorepo/blob/e863d2fad8175bf55c08e9216fce8704ac679ff0/packages/docs/src/core/src/spec/transpilation-details.rst)address(this).balancecall, for similar reasons (this compiles to theSELFBALANCEopcode, 0x47` which is reasonably new, which isn't mentioned anywhere in their docs, but is clearly not supported as a result).This at least got the contracts compiling. But tests fall as soon as they try to
calla function, which happens in the fourth migration. This is as far as I've gotten so far :smile:
