out of nowhere i started receiving floods of 0.00000001 nmc

0.0014 and rising in 0.00000001 lots... is this bad for anything?

This was noticed by the operator of blockexplorer.sytes.net and mentioned on IRC recently. I posted about it here. It can cause issues with the wallet. Litecoin recently had a 'dust spam attack' which caused issues with users, pools and exchanges. Their workaround (apart from adjusting fees) was to make the wallet ignore low value transactions.

my wallet.dat is up to 200MB and i get connection errors now :/

any idea on a fix i can do after the fact?

To purge my wallet from dust transactions (0.00000001 only), i used that script while number of reported tx is not 0 + a modified deletetransaction rpc command :

Code: Select all

while true; do echo -n "Deleted : "`nmc listtransactions "*" 1000|grep '"amount" : 0.00000001' -A2|grep '"txid" : "'|cut -d'"' -f4|sort|uniq|wc -l`" / "; for txid in `nmc listtransactions "*" 1000|grep '"amount" : 0.00000001' -A2|grep '"txid" : "'|cut -d'"' -f4|sort|uniq`; do nmc deletetransaction $txid; done |wc -l; sleep 0.1s; done

Here is the patch to allow deletion of transactions already in the blockchain :

Code: Select all

diff --git a/src/namecoin.cpp b/src/namecoin.cpp

       CWalletTx wtx = pwalletMain->mapWallet[hash];
       UnspendInputs(wtx);

ps : my wallet is still big due to a lot of address generated maybe ? (in my debug.log i have : mapKeys.size() = 129354)

I'm a windows user that uses the GUI

with the new binaries now it just crashes after a while (both the GUI and just namecoind)

what would happen if i tried to use an old backup of my wallet with the new binaries? it has the spammed address in it but not the spam (or whatever made it big)

is there a way to get my other addresses out of my wallet and make a new wallet that would work?

i deleted the spammed address from my pre spam backup wallet and tried that, seems to be working.
