[ANNOUNCE] Abe 0.7: Open Source Block Explorer Knockoff

[bitspill]

Is this good software to use as a bitcoin block explorer on a web server that will get a moderate amount of traffic, or is it too slow/bulky?

If it is not good for that purpose, are there any open source alternatives?

Thanks in advance for any answers or thoughts!

What's your definition of “moderate traffic”? What are you anticipating in terms of page views per second?

Cheers

I'm willing to offer a bounty to anyone who will create a block explorer for a coin that already exists but has no current working block explorer. Is it possible or can only the dev make that ? PM me if you're interested. Thanks.

how to run abe without logs in console?

how to run abe without logs in console?

To run as daemon in background:

Code:

nohup ABE COMMAND TO RUN &

Log will be saved to nohup.out. You can create symlink to /dev/null if you do not want to save logs. Or if not in background:

Code:

ABE COMMAND TO RUN > /dev/null

thanks for reply. do you mean running commad may look like

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

?

Yes that would do it. However screen may be a better choice so you can check in if necessary.

Sudo apt-get install screen
screen python -m Abe...
Ctrl-A
D
Then if you want to check back later to see the console
screen -r

Hi,
I'm running bitcoin-Abe on fastcgi environment.
i make changes in the html code but it doesn't seem to effect my page at all.

I tried to delete .pyc files and restart apache with no success.

Thanks in advance

Any suggestions for the best way to get the raw hex of the genesis transaction for the file below?

https://github.com/bitcoin-abe/bitcoin-abe/blob/master/Abe/genesis_tx.py

Since RPC does not return this I'm guessing I need to parse the blockchain file.

It should be checkpoint #0 in the checkpoints.cpp file found in the source code. IIRC

Hi guys.

Hope all is well with everyone.  I'm fairly new to crypto so for the abe experts out there I've got a question.  Do you think it's technically feasible to modify abe to work with multi-difficulty-algo coins such as myriad coin or digibyte?  The reason I ask is I use abe's backend database to create mining stats / charts / richlist for a coin I follow as a hobby that is likely going to move to multi-algo.  see nlgstats.iblogger.org for an example of some of the things I get by using abe.  I'm not an html guy so it's not very pretty.  Am I better off transitioning to something like insight?  I really like working with abe, hate to move to something else.  Cheers.  All the best --Mark

Hi all,

Does anyone know the address_version for Bitbay or Mue
/Abe/Chain/ no Bitbay chain

and:
    {"chain":"Bitbay", "policy":"Sha256Chain",
     "code3":"BAY", "address_version":"\x49", "magic":"\xfb\xc0\xb6\xdb"},

    {"chain":"Bitbay", "policy":"XXX",
     "code3":"BAY", "address_version":XXX, "magic":"XXX"},

The XXX part I used from a other currency..

Hello

I've migrated my super node and dns seed to a high performance VPS. The last thing to do is moving bitcoin-abe.
Because my host gave me an offloaded mysql database, I couldn't import the SQL files genereted by mysqldump due to not having mysql "super privileges".
The only option left is rebuilding the database. This seems to fail unfortunately:

Code:

python -m Abe.abe --config minerals-abe/abe-min.conf --commit-bytes 100000 --no-serve
Reconnecting after rollback error: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")
Reconnecting to database.
Reconnecting after rollback error: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")
Reconnecting to database.

The connect-args are:

Code:

connect-­args {"user":"XXX","db":"XXX","passwd":"XXX","host":"19X.2X1.X5X.X4X","port":3306}

Although I can connect with the mysql command to my database, bitcoin-abe seems to be obstinately trying to connect using a unix socket. How is that even possible? If you don't give a remote server's IP, leave it empty or just enter 127.0.0.1 or localhost, it connects to the local MySQL DB by default, using the socket, but as soon as you specify and IP address, it should connect over TCP. Unless I misread the error log above, it still want to connect to a local MySQL DB? How do you use bitcoin-abe with a remote  database?

hey guys,

trying to get abe working for Lottocoin, getting this:

did try several things, nothings helps...

don't remember the exact option but in the config file set inttype to string or something along those lines

Edit:
Abe.conf

# Some databases have trouble with the large integers that Abe uses
# for statistics.  Setting int-type=str causes Abe to pass certain
# integers to the database as strings and cast them to floating point
# in SQL expressions that calculate statistics.  Try this if SQLite
# complains "OverflowError: long too big to convert".
#int-type str

thx for that, saw it and tried it but using MySQL. Still the same. known error in python 2.7 -> http://bugs.python.org/issue21816 ?
