[ANNOUNCE] Abe 0.7: Open Source Block Explorer Knockoff

[natecv8]

Hi John,

Thanks for all your work on ABE, it's a great piece of software. I have loaded in a few blockchains now, but there's one in particular I am having issues with and I see some strange behaviour that I haven't been able to understand. I am trying to load in the Datacoin blockchain which is a primecoin based chain with additional data structures for storing data in the blockchain.

I understand Abe won't be able to parse the data component which I am going to do separately with Datacoin tools, I am looking to import the transaction information via RPC however ABE is making a strange RPC call that the daemon doesn't like causing it to fail.

I have defined the coin details in abe.conf and specified the genesis block transaction:

Code:

import-tx += 01000000010000000000000000000000000000000000000000000000000000000000000000ffffffff350002e7033068747470733a2f2f626974636f696e74616c6b2e6f72672f696e6465782e7068703f746f7069633d3332353733352e30ffffffff0100e1f50500000000000000000000

datadir += [{
        "dirname": "/usr/src/dev/bitcoin/blockchain/datacoin/",
        "chain": "Datacoin",
        "code3": "DTC",
        "address_version": "\u001e",
        "loader": "rpc",
        "conf": "/usr/src/dev/bitcoin/blockchain/datacoin/datacoin.conf"
      }]

However when I run abe, it throws an error from the RPC call to get the next block:

Code:

python -m Abe.abe --config abe.conf

Falling back to default (Bitcoin) policy.
RPC failed: ('http protocol error', 0, 'got a bad status line', None)
Failed to catch up {'blkfile_offset': 0, 'blkfile_number': 1, 'chain_id': 11, 'loader': u'rpc', 'conf': u'/usr/src/dev/bitcoin/blockchain/datacoin/datacoin.conf', 'dirname': u'/usr/src/dev/bitcoin/blockchain/datacoin/', 'id': 18L}
Traceback (most recent call last):
  File "Abe/DataStore.py", line 2511, in catch_up
    raise Exception("RPC load failed")
Exception: RPC load failed

I did a tcpdump of the RPC request and I can see that for some reason, Abe is requesting block height 'x' which is causing the daemon to immediately drop the connection. The same command from the command line also throws an error:

Code:

POST http://127.0.0.1:11777 HTTP/1.0
Content-Type: application/x-www-form-urlencoded
Content-Length: 70
Authorization: Basic [...]
Host: 127.0.0.1:11777
User-Agent: Python-urllib/1.17

{"params": [0], "jsonrpc": "2.0", "method": "getblockhash", "id": "x"}

Any idea where the x is coming from? I looked all through DataStore.py at where get_blockhash is used and from what I can see it's meant to be requsting block height 0.

[unick]

Did you update the source recently?

Another odd behaviour I get is when I try to read the pubkey_hash from the database, I get gibberish characters, so my script fails since it can't recognize the actual public key.

I'm trying to pinpoint the issue, any ideas?

All my databases are configured the same so that's why I wonder if there was a code change influencing this.

EDIT: ok, I think I found it, the column type for pubkey_hash is now binary(20), previously it was char(40).  The first question that comes into mind is why this was changed ?

Would anyone be interested in creating a block explorer/rich list for XLB (LibertyCoin). We have a 3000 XLB balance and I'm willing to add a lil more if needed. Please PM me if interested, or irc.freenode.net #libertycoin

Thanks

Hi.
Tracking down a premine I want to understand better, I found this thing I think is anomalous:

cryptoblox.com/address/1JxY6A5jgjGysUFFpkYwA6g3ZVkDCyPjdM
cryptoblox.com/address/8xNzoDkDBA5dQhtuHiszNUqzX5e8kLqUiy

they belong to 2 different addresses but have same amount, TXID etc.

I'm kind of new to this blockchain things and I'm probabily missing something.

Anyone would care to clarify it for me please?

Thanks.

hi, I checkout the branch "geekz-patch-1".

It work fine except the block list(/chain/xxx). The browser shows

Code:

DataTables warning (table id = 'chain'): DataTables warning: JSON data from server could not be parsed. This is caused by a JSON formatting error.

It happened when enter a chian or changed the display number of per page. It just always display 10 blocks data and couldn't changed.

Can you tell me how to fix it?

I know it use the new API: /q/get_blocks_data

But when i directly browser this api with some json parameters, it shows error info like this:

Code:

Juse like:

His pages are OK without json errors. Why?

I also find someone's block chain worked fine while the error exist.
Juse like:
http://magichain.info/q/get_blocks_data

His pages are OK without json errors. Why?

Fixed these by myself.  There is the solution:

First bug is that /q/get_blocks_data shows python error because of the code here:

abe.py:

Code:

def q_get_blocks_data(abe, page, chain):
        """shows the latest blocks data in json format for datatable in chain page"""
        page['content_type'] = 'application/json'
        latest_blocks = []
       total_number_of_blocks = abe.get_max_block_height(chain)
        post_data = get_post_data(page)
        if chain is None:
            return 'Shows latest blocks.\n' \
                '/chain/CHAIN/q/get_latest_blocks[/INTERVAL[/START[/STOP]]]\n'

total_number_of_blocks = abe.get_max_block_height(chain)
chain is none before be checked:if chain is None

fix with code:

Code:

def q_get_blocks_data(abe, page, chain):
        """shows the latest blocks data in json format for datatable in chain page"""
        page['content_type'] = 'application/json'
        latest_blocks = []
       #total_number_of_blocks = abe.get_max_block_height(chain)
        post_data = get_post_data(page)
        if chain is None:
            return 'Shows latest blocks.\n' \
                '/chain/CHAIN/q/get_latest_blocks[/INTERVAL[/START[/STOP]]]\n'
       total_number_of_blocks = abe.get_max_block_height(chain)

Second bug is caused by mysql with the default abe.conf.

Code:

# To use MySQL binary types, set binary-type=binary. This may become the
# default on databases that support it.
#
# The binary-type setting affects only the first run, where Abe
# creates its tables.
#binary-type hex

The conf set binary-type=binary.

But abe.py created json like this code in:
def q_get_blocks_data(abe, page, chain)

Code:

latest_blocks.append([int(height), hash, format_time(int(nTime)), int(num_tx), format_satoshis(value_out, chain),
                                      util.calculate_difficulty(int(nBits)),format_satoshis(satoshis, chain), avg_age, '%5g' % (seconds / 86400.0), percent_destroyed])

The "hash" is binary. Json couldn't decode it.
So, replaced with abe.store.hashout_hex(hash)

Code:

latest_blocks.append([int(height), abe.store.hashout_hex(hash), format_time(int(nTime)), int(num_tx), format_satoshis(value_out, chain),
                                      util.calculate_difficulty(int(nBits)),format_satoshis(satoshis, chain), avg_age, '%5g' % (seconds / 86400.0), percent_destroyed])

Hi

I'm attempting to run a forked Abe (for ultracoin) using fastcgi on my server. I have root access and for the time being everything everything is setup as root.

I have downloaded the UTC blockchain data files and all my other files seem to be in the correct place but I still can't get Abe to run on my domain on port 80

I've spent a couple of days changing permissions, reinstalling etc but cannot get anywhere.

Instead when I view Abe @ http://mydomain.com  I am confronted with 'internal server error' - a look at the log says 'premature end of scripts headers on abe.fcgi

Code:

[Sun May 18 01:34:03 2014] [warn] [client ***.***.***.***] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[Sun May 18 01:34:03 2014] [error] [client ***.***.***.***] Premature end of script headers: abe.fcgi

I don't understand why this is as I have followed the be fastcgi instructions to the letter, creating the necessary files and directories, making them executable.  

I have repeated the process numerous times and am nearly ready to throw in the towel  and i'm no quitter.


My abe.conf file @ /home/ultra/abe-utc/abe.conf

Code:

This looks like a wrong port/server IP or port in use.

If I recall I couldn't make abe work with apaches sites enabled feature. So I used the default config and modify accordingly.

So instead of this in /etc/apache2/sites-enabled/abe

Hi

Thanks!  I tried this but still cant connect using fastcgi.  It's weird. I've tried everything about 5 times and still no luck.  It begins by successfully reading data via rpc but then buckles when it tries to establish a connection to apache2.  It looks like it could be permissions. perhaps python not being able to connect to apache rather than colliding with an existing connection on port 80. I've even disabled the default site so my httpd conf info in 'abe' is the only site running.  

I've removed the port & host data from abe.conf

Code:

Never saw this message before, what does it mean?

Thanks

EDIT: from what I understand, Abe test for the block to see if it's proof-of-stake...

EDIT: I used an older version of abe.py and the error went away. Still any clues on why I get this error would be appreciated

I made a VeriCoin block explorer (http://blocks.vericoin.info) which is a NovaCoin deriv. and am getting the same error as you. Could you pastebin your abe.py file? Thanks!

I'm trying to set a new block explorer... Abe reads the blockchain fine and loaded the database without a itch.

I get an error when I try to access the block details page.  Any other page loads fine. I use FastCGI

here's the error (last call)

Code:

is_stake_block undefined, is_stake_chain = True, b = {'chain_candidates': [{'chain': <Abe.Chain.AsiaCoin object>, 'in_longest': Decimal('1')}], 'chain_satoshi_seconds': 2517292340726300000000L, 'chain_satoshis': 3342705000000000, 'chain_work': 13618916087790469, 'fees': 57000, 'generated': 5000000000, 'hash': '00000000001930548377e3e15c927d8d79278cb8ba53b1d015468609e3085b13', 'hashMerkleRoot': '36f8065b8c6c95b37c426fbf95bb0bcf98dc04817de8257ffd624d8311cb2603', 'hashPrev': '000000000141a8721757560bb837c6d7be9aa85cf5333bfeaff2602c9d9a1d7a', 'height': Decimal('12441'), ...}

I was able to get around the error by commenting out the following lines of Abe.py:

        is_stake_chain = chain.has_feature('nvc_proof_of_stake')
        is_stake_block = is_stake_chain # and b['is_proof_of_stake']

and

  if tx is b['transactions'][0]:
      assert txout['value'] == 0
      assert len(tx['out']) == 1
      body += [
   #   format_satoshis(b['proof_of_stake_generated'], chain),
  ' included in the following transaction']


I think there's a bug in DataStore.py where the values b['is_proof_of_stake'] and b['proof_of_stake_generated'} are set.

Hi everyone, Are you facing any instability in your block explorer installation with the new design at https://github.com/bitcoin-abe/bitcoin-abe/tree/geekz-patch-1 ?

I had pushed/published the new design for ABE , you can view it at https://github.com/bitcoin-abe/bitcoin-abe/tree/geekz-patch-1 . But I myself have not been able to get stable performance using it.
Currently i am using digitalocean instance with 2GB RAM for site at http://ancblockchain.com and the site is not stable.  
This can also because of hosting provider.  Can anyone please suggest me a good hosting provider?

Please help me friends.
I would be able to push/publish more new features in Abe Explorer, for the benefit of community. But i need to get it working properly.  

[geekz]

Important change to be done to display correct address value in transaction pages , for new eXplorer theme design of Abe:

Visit this link to see the change https://github.com/geekz/bitcoin-abe/commit/f2cce3e6ff020b2655195e73e7a72824bf42bf50

In line number 744 , inside the function row_to_transaction function, you have the following.

Code:

                  body += hash_to_address_link(chain.address_version,row['binaddr'], '../')

Change the above mentioned line to

Code:

                body += abe.format_addresses(row, '../', chain)

Hello!

OPEC Coin needs a blockexplorer from launch (countdown)

Here's OPEC Coin thread https://bitcointalk.org/index.php?topic=633593

We've got a 2500 OPC bounty for setting up blockexplorer!

Please PM me if interested to reserve this bounty!

Thanks!

[geekz]

Finally , found the issue.
I had created sitemaps for the site , so that google can crawl the site.
But google started sending multiple requests per second to the site. And the site was not able to handle it.
Finally fixed it by requesting google to reduce crawl rate also increased maxconnection in apache configurations.  So, things are looking more stable now.  

Hurrey!

Hi geekz,

I am Dev of Magicoin, and we have a dedicated server available. I think you did a very good & nice block explorer. Magicoin's explorer benefits very much from your work too. For this, I will be happy to provid a host for you either for test purpose or for long-term hosting. PM for discussion if you are interested.

[unick]

This looks like a wrong port/server IP or port in use.

If I recall I couldn't make abe work with apaches sites enabled feature. So I used the default config and modify accordingly.

So instead of this in /etc/apache2/sites-enabled/abe

Code:

 <VirtualHost *:80>
        ServerName mydomain.com
        Alias /static/ /home/ultra/abe-utc/Abe/htdocs
        Alias /robots.txt /home/ultra/abe-utc/Abe/htdocs/robots.txt
        Alias /favicon.ico /home/ultra/abe-utc/Abe/htdocs/favicon.ico
        Alias / /usr/lib/cgi-bin/abe.fcgi/
        # FcgidIOTimeout 40
</VirtualHost>

try instead adding

Code:

        ServerName mydomain.com
        Alias /static/ /home/ultra/abe-utc/Abe/htdocs
        Alias /robots.txt /home/ultra/abe-utc/Abe/htdocs/robots.txt
        Alias /favicon.ico /home/ultra/abe-utc/Abe/htdocs/favicon.ico
        Alias / /usr/lib/cgi-bin/abe.fcgi/
        # FcgidIOTimeout 40

in /etc/apache2/sites-enabled/default <VirtualHost *:80></VirtualHost> tags.

Hi

Thanks!  I tried this but still cant connect using fastcgi.  It's weird. I've tried everything about 5 times and still no luck.  It begins by successfully reading data via rpc but then buckles when it tries to establish a connection to apache2.  It looks like it could be permissions. perhaps python not being able to connect to apache rather than colliding with an existing connection on port 80. I've even disabled the default site so my httpd conf info in 'abe' is the only site running.  

I've removed the port & host data from abe.conf

Code:

Try adding --no-serve switch to your execution command

Code:

python -m Abe.abe  --config /home/ultra/abe-utc/abe.conf --static-path /static/ --no-serve
