Error: oversized data

[basilji]

While deploying contract in ethereum private blockchain using web3

web3.eth.contract(JSON.parse(contractabi.toString('utf8')));
mycontract.new({
from: web3.eth.accounts[0],
data: codebin,
gas: 3141592
}

I am getting below error
Error: oversized data

same here

Same here. Not sure how to put the maxCodeSize in it

[nivida]

Which version of web3 are you using?

[nathanawmk]

Since maxCodeSize parameter in genesis.json does not work, I had to fix this issue by increasing the transaction size to 64KB in tx_pool.go. To be specified, this is for Quorum, a fork from Ethereum for enterprise use.

DOS is less applicable for private Ethereum networks such as Quorum.

Updated code as follows:
// Heuristic limit, reject transactions over 32KB to prevent DOS attacks

// UPDATED to 64KB to support the deployment of bigger contract due to the pressing need for sophisticated/complex contract in financial/capital markets - Nathan Aw

if tx.Size() > 64*1024 {
	return ErrOversizedData
}

we were using web3 - 0.19.0 version

@basilji
Maximum data you can pass along with single transaction is 32KB. Out of that Apprx 1KB is used for transaction details and rest is actually available to the sender to add payload. Modularize your smart contract code and use multiple transactions to deploy large smart contracts.
Error is thrown from Geth side, look at this line of code https://github.com/ethereum/go-ethereum/blob/6a33954731658667056466bf7573ed1c397f4750/core/tx_pool.go#L570 Limit is 32KB to prevent DOS attacks

@nathanawmk
I have done this if tx.Size() > 128*1024 { return ErrOversizedData }.Even after doing this when I am deploying my smart contract to my private network it is still giving Error: oversized data. I have also tried to find the deployedBytecode length in mycontract.json file. I found out that it is 71236.

this is the question we are discussing.

This is an issue of 0.20.7 and the last maintenance release happened some months ago. Because of this do I close this issue.
