@holiman On the private network, we have contract code as genesis contract. We want to update it in the running network. We are thinking it following way:
Add new field in genesis say contract_alloc and it will have block number n, contract address, and new code. At n block, it will take in affect at give contract address and remains after that nth block. To do so, we have to change the state DB.
Do you think is it the right approach? If yes, when and where should we make state DB changes? In engine.finalize of n-1?
trying to generate some go bindings from this sol file, but it is missing some functions from imported libraries.
https://github.com/tellor-io/TellorCore/blob/master/contracts/Tellor.sol
for example ./libraries/TellorLibrary.sol imports TellorGettersLibrary.sol which has didMine function but this is not added in the generated golang file.
Any idea if I am doing anything wrong or is this some limitation or expected behavior?
command is abigen --sol=abi/Tellor.sol --solc=solc0.5.16 --pkg=contract --type=Tellor --out=pkg/contract/contract.go
TellorGettersLibrary.sol directly it still doesn't create the didMine function call/home/krasi/bin/abigen-v1.9.23 --sol=abi/libraries/TellorGettersLibrary.sol --solc=/tmp/bin/solc --pkg=contract --type=Tellor --out=pkg/contract/contract.go
Hi all, I’m having trouble connecting my graph-node to my local geth node. I’m using this command to connect:
cargo run -p graph-node --release -- --postgres-url postgresql://postgres:postgres@localhost:5432/graph-node --ethereum-rpc mainnet:127.0.0.1:8545 --ipfs 127.0.0.1:8080 --debug
which gives this error:
thread 'main' panicked at 'Failed to connect to Ethereum RPC: Transport("RelativeUrlWithoutBase")', chain/ethereum/src/transport.rs:50:14
geth command used to sync the node:
geth --syncmode fast --cache 2048 --light.maxpeers 0 --datadir "./blockchain-data" --http --http.addr localhost --http.port 8545 --http.api personal,eth,web3,admin,txpool,debug --http.vhosts “*” --ws --ws.addr "0.0.0.0" --ws.port 8546 --ws.origins "*" --ws.api personal,eth,web3,admin,txpool,debug
I’m able to get a response via this web3 test script from the geth node. It properly returns the latest block:
var Web3 = require('web3');
var provider = 'http://127.0.0.1:8545';
var web3Provider = new Web3.providers.HttpProvider(provider);
var web3 = new Web3(web3Provider);
web3.eth.getBlockNumber().then((result) => {
console.log("Latest Ethereum Block is ",result);
});
If anyone has any insight into what the problem could be please let me know.
--ethereum-rpc mainnet:http://127.0.0.1:8545 instead of --ethereum-rpc mainnet:127.0.0.1:8545 I get this:Oct 28 02:14:02.198 INFO Connecting to Ethereum..., capabilities: archive, trace, network: mainnet

cargo run command used to sync the graph node outputs INFO Syncing 50 blocks from Ethereum., code: BlockIngestionLagging, blocks_needed: 50, blocks_behind: 85, latest_block_head: 11148790, current_block_head: 11148705, network_name: mainnet, component: BlockIngestor so this leads me to believe I'm connected. Also worth noting, I'm seeing on github/stackoverflow that using geth --syncmode full rather than fast potentially fixes the issue. I'm hoping that's not the solution. If anyone has any insight please let me know
