BUG: get block header on height pending failed #395
Description
Versions 0.9.1/ 0.9.1b:
OS: Linux
I run a pool with custom Open Ethereum Pool code. Every couple of days or so my unlocker receives this error from the MVSD:
Unlocking suspended due to last critical error: get block header on height pending failed.
Error returned from explorer/extensions/commands/fetchheaderext.cpp.
auto ret = miner.get_block_header(block_header, argument_.number);
consensus/miner.cpp:
bool miner::get_block_header(chain::header& block_header, const std::string& para)
{
if (para == "pending") {
block_ptr block = get_block();
if (block) {
block_header = block->header;
return true;
}
}
else if (!para.empty()) {
blockchain::block_chain_impl& block_chain = node_.chain_impl();
uint64_t height{0};
if (para == "latest") {
if (!block_chain.get_last_height(height)) {
return false;
}
}
else if (para == "earliest") {
height = 0;
}
else if (para[0] >= '0' && para[0] <= '9') {
height = std::stoull(para);
}
else {
return false;
}
if (block_chain.get_header(block_header, height)) {
block_header.transaction_count = block_chain.get_transaction_count(height);
return true;
}
}
return false;
}
block_ptr block = get_block();
This part must be failing somewhere. I thought the recent 0.9.1b "BUGFIX: getblock error from height: 3584831 3585067 3585179 because of parsing json format error caused by NaN raw data to resume user scaning MVS blocks." might have been related. But appears not. Any help appreciated.
