bitcoind have some problem when support regtest mode

[wanggeng01041454]

bitcoin.conf 's content like this:

chain=regtest

txindex=1
server=1
rest=1

[regtest]
port=18444

rpcallowip=0.0.0.0/0
rpcbind=0.0.0.0
rpcport=18443
rpcuser=bitcoin
rpcpassword=opcatAwesome
rpcworkqueue=2048
rpcthreads=32
rpcservertimeout=120

maxconnections=50

run bitcoind

and then , run bitcoin-cli -generate 1 to generate a block.

bitcoind print following log:
"""
2024-09-29T10:23:17Z ERROR: CheckProofOfWork : block does not have our chain ID (got 8192, expected 8228, full nVersion 536871168)
2024-09-29T10:23:17Z ERROR: ProcessNewBlock: AcceptBlock FAILED (high-hash, proof of work failed)
"""

I guess the reason is that you forget to set ChainId of block.
BECAUSE I can avoid the problem in a extremly strange way!

bitcoind -blockversion=539230208

I get the number in the following way:

#include <stdio.h>
#include <stdlib.h>

// void SetChainId(u_int32_t chainId)
// {
//     nVersion %= VERSION_CHAIN_START;
//     nVersion |= chainId * VERSION_CHAIN_START;
// }

static const int32_t VERSION_CHAIN_START = (1 << 16);
u_int32_t chainId = 0x2024;
static const int32_t VERSION_AUXPOW = (1 << 8);

int main()
{
  u_int32_t nVersion = 536871168;
  nVersion %= VERSION_CHAIN_START;
  nVersion |= chainId * VERSION_CHAIN_START;

  nVersion &= ~(VERSION_AUXPOW);

  printf("nVersion: %u\n", nVersion);

  return 0;
}
