This is the query that screws everything up Edit: WELL, found the problem: http://blockexplorer.com/testnet/tx/c333a53f0174166236e341af9cad795d21578fb87ad7a1b6d2cf8aa9c722083ca crazy block in testnet blockchain. Now I have to figure out how to skip this block. I don't know when I'll have time to fix this, but I'm glad we see it on testnet before main. Thanks. |

John, check the edit2, previous post: I included it. About the strange transaction: it's bread for gavin's teeths but since the block is old, I guess he already know about this.

Shows only the first block. The thing I do not understand.
When Abe loads many blocks but shows only the genesis block, it means that Abe is using the wrong algorithm to calculate the block header hash as it appears in the next block's hashPrev field. By default, Abe uses double-SHA256, the same as Bitcoin. Many coins use scrypt. I would like to make this selectable by datadir=[{...,"hashPrev":"scrypt"}], but for now it requires a few lines of code. Look for "NovaCoin" in the sources for an example. |

Shows only the first block. The thing I do not understand.
When Abe loads many blocks but shows only the genesis block, it means that Abe is using the wrong algorithm to calculate the block header hash as it appears in the next block's hashPrev field. By default, Abe uses double-SHA256, the same as Bitcoin. Many coins use scrypt. I would like to make this selectable by datadir=[{...,"hashPrev":"scrypt"}], but for now it requires a few lines of code. Look for "NovaCoin" in the sources for an example. is there a way to get a raw block before abe splits it and puts it in the database, maybe there are new fields added in this coin, or the data got moved around, I can then change the abe code to make it work |

Yep, read this and make everything as described. I found, that sudo make some troubles, hard to find it. So, i bypass it, truncate abe.fcgi to #!/usr/bin/python
import subprocess, sys, os
command=["/home/berg/exeblockexp/abe", str(os.getpid())]
subprocess.Popen(command, stdin=sys.stdin).wait()
this is sudo log, if it useful Mar 20 02:00:21 noc sudo: apache : TTY=unknown ; PWD=/var/www/localhost/htdocs/execoin ; USER=berg ; TSID=000028 ; COMMAND=/home/berg/exeblockexp/abe 13410

So my guess, and I'm no expert nor do I know how to fix this, is that Abe can't read the lenght of the block properly? or like the error says, the merkle root is off... I'm willing to help searching but I'm a bit over my head with this so a few pointers in the right direction would be appreciated. Thanks |

datadir=[] you will notice that I don't want abe to load in "server" mode and read the block chain, just want it to connect to the database and read it's content. I used another Abe instance to read the blockchain and update the database. If you followed the guide, it is mentioned how to add your "abe" user (the one that will run the FastCGI script) to the sudoers file so your apache user can access the FastCGI script without password and be able to run it. Make sure you edit your sudoers file with visudo and append to it # This allows the Apache account (www-data) to run Abe as USER.

Our coin Fuguecoin is very necessary Block Explorer. I now pronounce the bounty for fist Block Explorer. (Must be able to find the balance of addresses.) Bounty: 1000 FC (0.05 BTC)

is it safe to assume that when using the RPC loader rather than the blkfile loader that it doesn't matter the algo of the coin since bitcoin-abe is using rpc call to get data ? I'm trying to setup fuguecoin using RPC here's my config datadir += [{"dirname": "/home/azureuser/.fuguecoin",

maybe I have the syntax wrong I'm sorry for the cryptic message. The problem is that you have to give --config (or --dbtype and --connect-args) along with --query if the query involves the database, as this one does. |

Two possible reasons: bad timing (I am busy) and no obvious answer. You have several questions, and it is not clear what you are currently using in terms of configuration and modifications to the code. You mentioned commenting out the Merkle root check, but your latest error shows it still occurring. Are you able to load blocks without the check? I have converted your hex dump back to binary, commented out the Merkle root check, installed the ltc_scrypt module, and loaded the block with this command: python -m Abe.abe --dbtype sqlite3 --connect-args :memory: --port 2750 --datadir '[{"dirname":".", "chain":"GrowthCoin", "policy":"NovaCoin"}]' |
