Is it possible to make Abe from a version of Tenebrix that uses the original Berkeley DB and is a clone of Multicoin unchanged since September 2011? I understand I might be able to run a localhost version to test out while I run my full node. It's the first Scrypt coin - Litecoin was the third but I understand they forked Bitcoin code and not MultiCoin.

Yes you can. I guess the question is why would you want to?
Abe is (was) a nice project, but there are many better explorers out there at the moment.
Kind of like tenebrix, was interesting back in 2011 now.......

Hi all

I've been trying to get an instance of Abe up and running but have run into a bit of a snag. Hoping someone can help me out here. I am running MySQL 5.7.33 and everything seems to be OK on that side. Abe is configured as below, and the data directory is working and reading blk*****.dat files seems to be fine.

Code:

dbtype MySQLdb
connect-args {"user":"abe1","db":"abe"}
upgrade
port 2750

I let it run on initial startup and everything seemed to be working as expected but I quickly ran into an error. The snippet below is from trying to force a rescan, but the error itself is the same.

Code:

block 4175 already in chain 1
block 4176 already in chain 1
Exception at 969746
Failed to catch up {'blkfile_offset': 968753, 'blkfile_number': 100000, 'chain_id': 1, 'loader': u'blkfile', 'conf': None, 'dirname': 'G:/Users/****/Downloads/Bitcoin Database/Bitcoin', 'id': Decimal('1')}

b = chain.ds_parse_block(ds)
File "Abe\Chain\__init__.py", line 81, in ds_parse_block
for i in xrange(nTransactions):
OverflowError: Python int too large to convert to C long

I found this in the config, but it doesn't seem to do anything.

Code:

# 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
int-type str

I've already tried deleting the database and rebuilding it, no luck. I've also made sure I'm running 64bit python and not 32bit - heard there were issues with int lengths. OS = Win 10

Any ideas on how to get this up and running?

Thanks in advance

What happens if there is a catch-up triggered by request A, then request B comes in?

B tries to "help" A catch up. Which would be okay if the loader code were free of bugs. Probably the easiest fix (when I--or someone--has time) is to enforce single-threaded loading with a database lock.

Your suggested workaround (one instance with --no-load, one with --no-serve) works like a charm and solves the problem.

Haven't had a problem since, thank you 1000!

I agree using some db-lock to only ever have one "db updater" would likely solve it, too.

Helly guys,
I'm new here, and i would like to clarify some points that i don't really understand so far.
1 - Is Abe a feasible explorer at this date (feb. 01 2018 ) ? How long it takes to load a full database in average?
2 - Where do i find the API containing all the calls and functions from Abe?
3 - Could anyone explain to me what function abe allow to query the bitcoin database?

Hello all,
Need help with configuration for Paccoin , I have posted issue here https://github.com/bitcoin-abe/bitcoin-abe/issues/234

Pulled latest version from git (master) and configured it for Paccoin (PAC).
abe.conf

Code:

dbtype MySQLdb
connect-args {"user":"abe","db":"abe","passwd":"pass"}
port 2750
host 0.0.0.0
upgrade
datadir += [{"dirname": "/root/.paccoin","chain": "Paccoin","code3": "PAC","address_version": "18"}]
address-history-rows-max 100000
default-loader = blkfile

Datastore.py

Code:

CONFIG_DEFAULTS = {
"dbtype": None,
"connect_args": None,
"binary_type": None,
"int_type": None,
"upgrade": None,
"rescan": None,
"commit_bytes": None,

"import_tx": [],
"default_loader": "default",
"rpc_load_mempool": False,
}
WORK_BITS = 304 # XXX more than necessary.
CHAIN_CONFIG = [{"chain":"Paccoin"}]

Chain/Paccoin.py

Code:

from .Sha256Chain import Sha256Chain

class Paccoin(Sha256Chain):
def __init__(chain, **kwargs):
chain.name = 'Paccoin'
chain.dirname = '/root/.paccoin/'
chain.code3 = 'PAC'
# MultiChain handshake is randomly created, so use Bitcoin compatible network settings as the default.
chain.address_version = '\x18' # dec 24 = hex 18 -- FROM paccoin/src/base58.h dec value PUBKEY_ADDRESS
chain.script_addr_vers = '\x1e' # dec 30 = hex 1e.
chain.magic = '\xe4\xe8\xe9\xe5' # \xe4\xe8\xe9\xe5 -- FROM paccoin/src/main.cpp value char pchMessageStart
#chain.address_checksum = '\x00\x00\x00\x00'
Sha256Chain.__init__(chain, **kwargs)
datadir_conf_file_name = "paccoin.conf"

After start got this error:

Code:

After few hours of searching for solution, I tried edit next files.

in deserialize.py :

Code:

d['nTime'] = vds.read_uint32()
# if has_nTime:
# d['nTime'] = vds.read_uint32()

got error:

next recommendation was edit
in Datastore.py :

Code:

#if chain is not None:
# Verify Merkle root.
#if b['hashMerkleRoot'] != chain.merkle_root(tx_hash_array):
# raise MerkleRootMismatch(b['hash'], tx_hash_array)

Hey Guys.
I got Abe Explorer up and showing. Ran cmd to load chain data for my coin, but for some reason it started sync. with WorldCoin instead of my-coin. Hhhhhmmmm, can't seem to find anything in script depicting WorldCoin at all.
Any ideas...

Do I need to set another network config in *.conf file except these to get Abe running?

Code:

# Specify port and/or host to serve HTTP instead of FastCGI:
port 2750
host localhost

It does not work after python -m Abe.abe --config abe-my.conf
But this python -m Abe.abe --config abe-my.conf --commit-bytes 100000 --no-serve command works as expected
I am using Ubuntu 14.04.
Any suggestions?

You may ask your question at Ubuntu forum, you will get fast answer there.

It's better to use Apache or other web server instead of internal one. For every new coin you must make only new datadir += .... etc.
I use separated config files, because some of my coins are hard to support (separate database and virtualhost).

it's the raw hex of the genesis transaction since there is a bug in the RPC where you can't get info about the genesis without looking at the block data files yourself, there's a note about it at the bottom of the file

Code:

# Extract your chain's genesis transaction data from the first
   # block file and add it here, or better yet, patch your coin's
   # getrawtransaction to return it on request:
   #if tx_hash_hex == ""
   # return ""

So when you try

Code:

getrawtransaction [merkleroot of gen_block]

The result should be

Where I can see this raw hex?

Code:

I see this advice but what exactley I have to do?
