Eloipool AssertionError

Hi, I have problem with eloipool, my error:

Code:

Traceback (most recent call last):

Make sure stratum is running correctly, and is available on the port you specified in the config.py

Thanks for reply but error is before server running. My conf:

### Settings related to poolserver logging

# By default, significant events will be printed to the interactive console
# You can customize your logging using either simple parameters, or Python's advanced logging framework
# Note that using Python's logging framework will override the default console logging!

# To simply log everything to the system log (syslog) as well:
# LogToSysLog = True

# To make a log file:
# LogFile = 'filename.log'

# For a rotating log file:
LogFile = {
	'filename': 'filename.log',
	'when': 'midnight',
	'backupCount': 7,
}
# For details, see:
# http://docs.python.org/3/library/logging.handlers.html#logging.handlers.TimedRotatingFileHandler

This appears to be a common issue with this fork

Did anyone tried this:

https://github.com/Tydus/eloipool-litecoin

?

Works ?

I tried it, can't get it to work.

I'm currently hung up on the following error:

Traceback (most recent call last):
  File "./eloipool.py", line 80, in <module>
    from bitcoin.txn import Txn
  File "/home/ltc/eloipool-litecoin/bitcoin/txn.py", line 146, in <module>

AssertionError

I can find in the original source Assertion Error: http://gitorious.org/bitcoin/eloipool/blobs/52dbd36b88482c4c675f8925eaa01c57c2a22b09/stratumserver.py#line161 in the stratumserver.py and it appears it is having an issue with the txid "keys" for litecoin. I guess try to contact the creator of litecoin fork at https://github.com/Tydus

Not sure of a quick fix at the moment

Ok, thanks for help

[Sannin]

I found other version and problem disappear. But I have another problem:

Code:

I think problem is wrong rpc connection settings:

Code:

TemplateSources = (
	{
		'name': 'primary',
		'uri': 'http://rpcuser:rpcpass@localhost:9344',
		'priority': 0,
		'weight': 1,
	},
)

Code:

UpstreamBitcoindNode = ('127.0.0.1', 9344) 

Where is the difference?

bitbar.conf

Code:

rpcuser=rpcuser
rpcpassword=rpcpass
rpcallowip=*.*.*.*
rpcport=9344

server=1
daemon=1
gen=0

Sorry for my english.

[reich]

They look the same to me

[reich]

Hmm thats a very strange error.

[reich]

Anyone agree?

[mike b.]

Problem is in python-bitcoinrpc.
look at authproxy.py, that is in python-bitcoinrpc/bitcoinrpc dir.

You can see smth like that:

Code:

 
131	        return json.loads(http_response.read(),
132	                          parse_float=decimal.Decimal)

but

Code:

return json.loads(http_response.read()

goes wrong, so i reccomend you to do some changes like:

Code:

131	        return json.loads(http_response.read().decode('utf8'),
132	                          parse_float=decimal.Decimal)

after that everything is ok. The reason is that there is no decode of auth string in python-bitcoinrpc.

And,  Sannin, can you tell me, what version of litecoin-eloipool did you use to get it work?

[mike b.]

is eloipool-litecoin still supported project?
i do some research and found that last git commit, that provides moving from standart bitcoin sha256 to litecoin scrypt brokes many things deep into eloipool.
