datastore.py----------------------
    {"chain":"CinnamonCoin",
     "code3":"CIN", "address_version":"\x1c", "magic":"\xcd\xf2\xc0\xef"},

cin.conf--------------
default-loader = blkfile
dbtype MySQLdb
connect-args {"user":"abe","db":"abe_cin","passwd":"<xxx>"}
datadir = /home/xxx/.CinnamonCoin
upgrade
port 2755
host 12.10.2.222

shell------------
python -m Abe.abe --config config/cin.conf --commit-bytes 100000 --no-serve

error:
Opened /home/xxx/.CinnamonCoin/blk0001.dat
Chain not found for magic number dbc0dbf2 in block file /home/xxx/.CinnamonCoin/blk0001.dat at offset 0.

why?????????
Should not find cdf2c0ef thing?
Why instead to search dbc0dbf2?

I'm seeing the same thing with Coino.  I think its pulling dbc0dbf2 from the block file, not the Chain definition in Datasource.py.  It appears not to be reading the Datasource.py file at all.  Did you figure this out?

Ahh, I seem to have solved my problem, instead of using Datasource.py I put a section like this in to my abe.conf file.

datadir += [{
 "dirname" : "/root/.feathercoin",
 "chain" : "FeatherCoin",
 "code3" : "FTC",
 "address_version" : "u000e",
 "magic" : "u00fbu00c0u00b6u00db"
}]


It is now building the DB.

I've been failing to receive topic reply notifications since mid-August.  Apologies for not noticing sooner.  If you posted a question since then and would like me to read it, please repost it or send me a link to it via PM.

Can a change to the best-chain criteria protect against 51% to 90+% attacks without a hard fork?

Hi there,
and thanks for making this.

I'm currently trying to set up bitcoin-abe for Netcoin (https://github.com/netcoinproject/netcoin) and I'm having a bit of problems.
I'm running the latest from github and have added the following to Datastore.py:

  {"chain":"Netcoin",
     "code3":"NET", "address_version":"\x70", "magic":"\xfd\xb6\xa5\xdb"}

...
....
block_tx 4071 3398
Skipped 1 bytes at block end
Exception at 7099887448213790924

Failed to catch up {'blkfile_offset': 39107, 'blkfile_number': 1, 'chain_id': 9, 'loader': None, 'dirname': '/home/myuser/.netcoin', 'id': Decimal('32')}

    (i,) = struct.unpack_from(format, self.input, self.read_cursor)
error: unpack_from requires a buffer of at least 8 bytes

Any ideas on what I'm doing wrong ?

I am having the same problem.

Hi there,

few days ago i setup a explorer for the Altcoin TheCypherfunk, i used the last git clone from abe.

Today i changed the design and also the css stylesheet with some new designfeatures. Actually i am working on a design useable on mobil devices like iPhone or iPad. If anybody is interessed i can send the changed files.

Cheers tuxie

I'd be keen on checking those changes out. Been toying with the idea of adding some flare to the original design but have been bogged down with too many other things at work which has taken away what little time i've had free over the last few weeks.

I've been trying for hours to fix this...this is the error I get.
Code:
WSGIServer: missing FastCGI param REQUEST_METHOD required by WSGI!
WSGIServer: missing FastCGI param SERVER_NAME required by WSGI!
WSGIServer: missing FastCGI param SERVER_PORT required by WSGI!
WSGIServer: missing FastCGI param SERVER_PROTOCOL required by WSGI!

If I start Abe using its own server, it is fine. However, this is no good for me as I want to run it as a website.

I have googled for literally hours. I have tried everything I can find and anything I can think of. Sure I'm probably missing something stupid...any ideas?

Assuming you have read the directions in README-FASTCGI.txt, can you get this sample FastCGI app to run?  https://docs.python.org/2/howto/webservers.html#setting-up-fastcgi

Abe runs the same way, using flup.server.fcgi.WSGIServer.

I've let the current version grind away for a week or two, only to get stuck on importing the Bitcoin blockchain.  On block 234062, it fails pretty spectacularly.  I probably shouldn't have been running this branch anyway as it doesn't handle scrypt coins, but that still doesn't explain what's going horribly wrong.  I'm running bitcoind 0.9.1 and told it to verify the entire blockchain; it came back with nothing wrong.  All this is on a freshly setup Ubuntu Server LTS 14.04 box (had been running late betas or release candidates); I'm using PostgreSQL for the database.

What follows is what Abe.py spits out when I try to have it resume.  Take particular note of the line that starts with "InvalidOperation: Invalid literal for Decimal:"

Code:
Opened /home/bitcoind/.bitcoin/blocks/blk00057.dat

I've let the current version grind away for a week or two, only to get stuck on importing the Bitcoin blockchain.  On block 234062, it fails pretty spectacularly.  I probably shouldn't have been running this branch anyway as it doesn't handle scrypt coins, but that still doesn't explain what's going horribly wrong.  I'm running bitcoind 0.9.1 and told it to verify the entire blockchain; it came back with nothing wrong.  All this is on a freshly setup Ubuntu Server LTS 14.04 box (had been running late betas or release candidates); I'm using PostgreSQL for the database.

What follows is what Abe.py spits out when I try to have it resume.  Take particular note of the line that starts with "InvalidOperation: Invalid literal for Decimal:"

Code:

  File "/usr/lib/python2.7/decimal.py", line 3872, in _raise_error
    raise error(explanation)
InvalidOperation: Invalid literal for Decimal: 'N26...'

Yeah wow, it's a doozy!  As near as I can make out, lookup_txout is getting that 17kB string as its txout_pos argument, so import_tx must have got it in txin['prevout_n'], which it got from tx.  Since you are loading from blkfile, tx must have come from chain.ds_parse_block (DataStore.py Line 2889) and ultimately from deserialize.parse_Transaction.  That gets txin from parse_TxIn, which gets txin['prevout_n'] from BCDataStream's read_uint32 method, and ultimately from the standard struct.unpack_from function.  This whole code path is very common in Abe and must have run millions of times successfully during your load before the error.

I would really like to know whether struct.unpack_from returns a 17kB string and, if not, where my chain of reasoning fails.  If so, it seems like a serious Python bug, and I would like to create a minimal test case and report it.

Scrypt coin configuration could be patched in after the fact, so you are okay there.

Can a change to the best-chain criteria protect against 51% to 90+% attacks without a hard fork?

I have tried all I know to get the fcgi module working under apache 2.4.7 Ubuntu 14.04

Here is my /etc/apache2/sites-available/abe.conf
Code:
<VirtualHost *:80>
        ServerName chain.distroblitz.co.in
        Alias /static/ /usr/local/lib/python2.7/dist-packages/Abe/htdocs

        </Directory>

        <Directory /usr/lib/cgi-bin/>
        Order allow,deny
        Allow from all
        Require all granted
        </Directory>

        # Raise this if you get server errors mentioning "mod_fcgid:
        # read data timeout in 40 seconds"
        #FcgidIOTimeout 40

        # Uncomment to log Abe requests.
        ErrorLog /var/log/abe_error.log
        LogLevel info
        CustomLog /var/log/abe_access.log combined

</VirtualHost>

I have checked filesystem permissions and I am able to run the fcgi with
Code:
sudo -u www-data /usr/lib/cgi-bin/abe.fcgi
The output when run from the command line generates errors which I assume are caused by not running it with fcgi
Code:
Abe initialized.

We need block explorer or crawler for coming soon upgrade, we can donate some super. Can anyone help here?

https://bitcointalk.org/index.php?topic=618552.0 is our official topic.

The source updated for 1.3 and we need simple block crawler or explorer for v. 1.3

I'm setting up Abe for Gabencoin just for fun.
It is a scrypt coin, and I have the litecoin_scrypt module installed from https://github.com/CryptoManiac/bitcoin-abe.

When it tries to load the data it stops immediately with this error:

Code:
MerkleRootMismatch: Block header Merkle root does not match its transactions. block hash=c012dbbcf46d3fcf17e4d66292775c5e34e54df16c3c62d45af2917435080000

I don't even know what that means, does it think the data is corrupt? I tried deleting my copy of the blockchain and let it fully sync up again, then turned off the daemon, but I still get that error right away.

My config:

Code:
datadir = [{
        "dirname": "/home/gabencoin/.gabencoin",
        "chain":   "Gabencoin",
        "code3":   "GBN",
        "address_version": "\u0010" }]

In case the address_version is wrong, an example address is 7nAd9jmuvgxtzmSLJFirWCTyoYguf5mA9k and I believe that is version 10 in hex.

I'm not even sure what else to look at.
