[ANNOUNCE] Abe 0.7: Open Source Block Explorer Knockoff

[roundrobin]

Update you database (sqlite/mysql/etc):
Set the right chain in chain_policy field in chain table. Use google

PLNcoin is a scrypt, so sha256chain (search the right name!!).

Sorry but this doesn't help me. Why do I need to change the SQL schema when I can set the policy in config from start, and why sha256chain instead of LtcScryptChain?

Hi, every once in a while my abe gets stuck on a http request and to unstuck it I have to attach to screen and control+c it, any idea how to get around this ?

Mine only does this when I don't run the web server and database portions separately.

Hey guys,

I'm looking to implement ABE for gridcoin, and have run into issues regarding extra block fields that abe isn't configured for.

Specifically, when I run a 'getblock' command within the client, I get the following:

Code:

getblock 3b487dc22d48d25dcbdc8e83073ffa0d6d4e61a490313894678d8fe2e9dac5f6

How on earth do I go about grabbing this from the blockchain.dat file? Does ABE perform a getblock command at any point, or is it only grabbing the .dat file and interpreting its' contents?

Is anyone willing to share a postgres sql dump of a bitcoin-abe db (BTC)?

I miss running sql queries on the blockchain, but last time I tried to build a db it just slowed down so much (around block 180000) it didn't seem feasable to build it myself.

For people having problems setting up Abe for a normal Litecoin/Scrypt clone on CentOS 6, I ran into a problem that I'd like to share the solution for:

I was using CentOS 6.5 for Abe, and kept running into an error "MerkleRootMismatch: Block header Merkle root does not match its transactions". After some days of almost going insane I finally found the reason why: http://framer99.blogspot.com/2014/01/centos-6-python-crypto-version-and-abe.html

I removed the old broken Pycrypto 2.0.1 package and built+installed the latest version from https://pypi.python.org/pypi/pycrypto/2.6.1 and now Abe at least manages to build the database.

Still one problem to solve: why it keeps saying there is only block 0 in the database despite having 75k blocks and 135mb large db...

[animalroam]

Is there a repo for X11?  If not, how do we support the algorithm?  Do we change policy to X11 and that's it?

[geekz]

How is the chain policy determined, and how does it help? Can someone please explain this to me.

If you are asking how it's set, it's set via the "chain" parameter, unless "policy" is set which is supposed to override, but I noticed that even in latest version Abe pre-0.8 what's set with "policy" is ignored. The parameter has no effect. You need to either duplicate a Chain file in Abe/Chain/ or change the chain_policy field in the chain database, or create a new default set in Abe/DataStore.py. Abe is a huge mess.

It's okay. I've worked most of it out. I'm only having issues getting FastCGI working. Does this on startup: http://puu.sh/9VIoO/9643ab40bf.png - There wasn't an original cgi-bin in USER folder so I had to make one.
Can you help?
Thanks

Here's the standard set of parameters for FastCGI - the formatting is for NGINX, you mave to remove/change some things:

Code:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

Shouldn't it be edited on git if the fastcgi directions aren't correct and don't include those parameters?

Getting Abe to work with nginx is not that easy. Try implementing it in apache with instruction provided in Readme-FCGI.txt file.
To implement nginx, you have to spawn fcgi , then point the proxy address to your domain or site.
I am still testing this to work with nginx, If anyone has expirence, please share the details.

I've finally managed to get Abe to work with a standard Litecoin clone. I don't understand what the LtcScryptChain module is for when it's THE WRONG MODULE for Scrypt chains, it must use Sha256Chain policy............... why no mention of this in the bitcoin-abe docs?!?!?!?

Anyway too much work with this, it's a big mess, I will keep using RPC Ace instead only need to see so the blockchain is working and check hashrates etc, it's much simpler and easier than bitcoin-abe.

[infernoman]

just wondering if anyone has been successful with running this in windows?

[edn247]

Trying to get this thing working with an X13 coin, is there tricks to doing this?  I have managed to get it working except for it only shows block 0...   Been a long road to get it working at all.

just wondering if anyone has been successful with running this in windows?

and im also wondering if abe comes with address transactions? so that i am able to see 24 hour input/outputs of addresses and possibly a rich list?

[raskul]

is there a step-by-step guide anyone can PM me to set up a block explorer using ABE please?

[crypto_cuttlefish]

Is it possible to get the balance of a wallet up to a particular block (via an api command)?
I want to be able to crawl a block chain and create a top-100 list for every 100 blocks to create an animation showing change of distribution over time.
Thanks.

I am setting up abe for my coin, which switched to merged mining at block 100k, and I'm getting an error.

Maybe you guys should try RPC Ace in the meanwhile to atleast get to see your blockchain while you fight with configuring ABE...... https://bitcointalk.org/index.php?topic=686177.0

Shouldn't be a problem if you have a working Python environment installed with the necessary modules (pycrypto).
