I'm trying to setup eloipool to replace my old pushpool install and I'm having a real hard time fixing an error that most ppl seem to have gotten past.

'No JSON object could be decoded'

I've tried 2 different builds of bitcond to connect to with eloipool but it always, always, always tells me that 'No JSON object could be decoded'.

These are the bitcoind builds I have compiled and run without any issues (connected to testnet) all RPC settings are correct and working as far as I can tell (Pushpool connects fine with the same RPC settings)

the standard - https://github.com/bitcoin/bitcoin
the precompiled sourceforge build - http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.8.2/bitcoin-0.8.2-linux.tar.gz/download

I've also followed these steps to build the source when all else failed - https://bitcointalksearch.org/topic/avalon-users-bitcoind-and-slushsgeneralfaults-mining-pool-setup-162788
I cant currently get the ubuntu ppa to download correctly so I haven't tried that one yet.

I've tried the few fixes that I have seen posted, like adding .decode() to the end of line 72 in authproxy.py, i've also tried rebuilding each one of the bitcoind's I downloaded and each time it always gives me the same error, I'm going crazy here trying to get eloipool to accept the returned JSON object from bitcoind.

What could the issue be?

Code:

Traceback (most recent call last):

FWIW, I don't intend to provide general support for patchsets which haven't even been proposed as merge requests yet (though anyone else is welcome to).
Hopefully this will encourage people to submit their changes upstream Wink

OK - i got rid of this strange message - it was just problem with python...

Bu i have a general problem with configuration: ShareTarget value is totally unclear for me and I used several calculators and can't get expected results as minimal difficulty. Can anyone help me with this?

feeleep

For pdifficulty 1, you want 0x00000000ffffffffffffffffffffffffffffffffffffffffffffffffffffffff; divide this by the desired difficulty for others.
For bdifficulty, it's the same, but based on a truncated value, 0x00000000ffff0000000000000000000000000000000000000000000000000000

If you enable dynamic targetting though, this is just a minimum, so I'd leave it at pdiff 1.

Hi,

I am testing litecoin fork of eloipool and i encountered an error which I can not pass through:

Hi, i am new to Python, started to learn it recently.
I have got Eloipool from https://gitorious.org/bitcoin/eloipool/commits/master

But there is no instructions on how to setup it on hosting server in README.
Also, does it support Litecoin mining?

What i am supposed to see is the site with frontend like http://eligius.st/~gateway (i know html/css3, so i need only up and running soft as site on hosting - then i will customize it)

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

It's better, but far from solved Sad

Perhaps the root cause hasn't been solved, but the problem is gone for now

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

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()

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.

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?

I got an error:

Code:

makeCoinbaseTxn	ERROR	Coinbaser failed!

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

Code:

nout = int(p.stdout.readline())

I guess CoinbaserCmd is invalid, then i run the command in terminal

Code:

echo -e "1\\n$((%d / 100))\\n1579aXhdwvKZEMrAKoCZhzGuqMa8EonuXU"

the result is:

Code:

bash: %d / 100: syntax error: operand expected (error token is "%d / 100")

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...

is it something with multithreading in eloipool ?

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 17:21:33,241	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?

***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:

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

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
