[ANN] Eloipool - FAST Python3 pool server software - GBT/stratum/dyntarget/proxy

[tomaszsz]

Miner talks to Eloipool.

ok it is easy

MMP talks to namecoind.

ok, thats easy too but

Eloipool talks to bitcoind and MMP independently.

which params (MMP url, MMP host, MMP port ? )

in eloipool makes that eloipool talks to MMP ? 

or my configuration

mining proxy command

Code:

python merged-mining-proxy  -w 8330 -p http://ssecreteloipool:222@127.0.0.1:9947/ -x http://namecoinrpc:manecoinrpcpass@localhost:9377/

eloipool config.py

Code:

# Secret username allowed to use setworkaux
SecretUser = "ssecreteloipool"

# Addresses to listen on for JSON-RPC GBT/getwork server
JSONRPCAddresses = (
        ('', 9947),
)

namecoind config

Code:

rpcuser=namecoinrpc
rpcpassword=manecoinrpcpass
 
 
 rpcport=9377

is ok, and i should just point miner to eloipool (port 9947 ) , instead  MMP (port 8330)   ?

You're missing the GotWorkURI stuff.

You saw README, right?

You're missing the GotWorkURI stuff.

You saw README, right?

yes , i saw

README:

"Eloipool supports merged mining using the setworkaux/gotwork RPC interface."

and in config.py

# URI to send gotwork with info for every share submission
#GotWorkURI = ''

and thats ALL...


 

SO
finall configuration

mining proxy command

Code:

python merged-mining-proxy  -w 8330 -p http://ssecreteloipool:222@127.0.0.1:9947/ -x http://namecoinrpc:manecoinrpcpass@localhost:9377/

namecoind config

Code:

rpcuser=namecoinrpc
rpcpassword=manecoinrpcpass
 
 
 rpcport=9377

Code:

and user miner program connect to 9947 

is it ok ?

Looks okay. Does it work?

I got an error:

then i do some debug

Got this new error any idea what this means?

Code:

May 10 08:04:05 <12>Change from height 235474->235476; no longpoll merkleroots available!
May 10 08:04:05 <12>clearMerkleRoots running out! only 0 left

Can anyone tell me how do I upgrade eloipool to latest release? And always was curious why Longpoll woke up has 2 lines and which one of them is accurate one says 20 clients and the other 5 clients weird? Also got another question does increasing the difficulty of shares mining reduces server load?

Code:

Longpoll woke up 20 clients in 0.278 seconds
Waiting 4.58 seconds to longpoll
Longpoll woke up 5 clients in 0.000 seconds

***PLEASE HELP***
I tried to upgrade everything python + eloipool. Now my pool doesn't work! It all started with simple

Code:

 import jsonrpc
ImportError: No module named jsonrpc

I have tried

Code:

cd python-bitcoinrpc
python3 setup.py build
python3 setup.py install
ls
cp -Rf jsonrpc/ /usr/local/lib/python3.2/dis-packages/

And it made it worse!

Code:

*** Solution***
found old pantehicon's fix!
A quick fix is to decode the bytes into UTF-8. On line 72 of bitcoinrpc/authproxy.py change:

Code:

Code:
self.__auth_header = "Basic %s" % base64.b64encode(authpair)
to read:

Code:
self.__auth_header = "Basic %s" % base64.b64encode(authpair).decode()

Hope this helps

what config would be required to run as a sub pool of eligius?

[optimator]

I have Eloipool up and running on Testnet.

When I find a block I receive this message in the log file:

Code:

2013-05-20 17:21:33,131	blockSubmission	DEBUG	Upstream 'primary' accepted block
2013-05-20 17:21:33,241	redflag	CRITICAL	Upstream 'primary' block submission failed: rejected

However, it appears the network has accepted the block.

Any ideas why I'm getting the "redflag" message?

[tomaszsz]

Looks okay. Does it work?

yes  many thanks
merged mining work ! (but i dont find any block yet )

but from time to time i get

is it something with multithreading in eloipool  ?

[tomaszsz]

I got an error:

Code:

makeCoinbaseTxn	ERROR	Coinbaser failed!

then i do some debug
line 105 in eloipool.py raise an error

Code:

any ideas?

My guess would be a non-BASH default shell...

I found the reason

Code:

p.stdout.readline()

return

Code:

b'-e 1\n'

My default shell is Bash，I use Python 3.3.1 on Ubuntu

If your default shell was BASH, you wouldn't get that result.

i have the same with BASH, python 3.2 , on ubuntu 12.

commenting CoinbaserCmd, may help but it isn't good solution...

I'm using bitcoind 0.8.1 and I'm getting a GBT timeout error.

You can see eloipool receives the new block notification, attempts to build the merkle tree using the transactions from GBT but then times out.

It's almost 50 seconds later the new block is pushed to the clients.

Any idea what is causing this error?

ValueError: No JSON object could be decoded

Its caused by a failed authorization. I tried to print the AuthHeader and got this as result: "Basic b'dXNlcjpwYXNzd29yZA=='"
If I put the string (without the b') directly into __auth_header it works flawlessy.

I also tried python3.3 with the same result.

[ppcko]

Quick and dirty fix? Works for me.
Add .decode() to the following line (authproxy.py):

Code:

self.__auth_header = "Basic %s" % base64.b64encode(authpair).decode()

[kinlo]

The GBT timeout issues are solved with bitcoin 0.8.2, best to upgrade.


Yes 0.8.2 hasn't been released yet.  But all pools have backported the related fix(es) in order to solve this problem already....

Or just use an existing pool
