will pay for p2pool development.

[guugll]

Hi all, searching skilled p2pool developers.
send PM if you are interested.
 

[sudo23]

hi
how much do you want to pay for dev p2pool?

[guugll]

my idea was 5-10 LTC

[markm]

So maybe 15 minutes to 30 minutes work or thereabouts?

-MarkM-

[guugll]

yes exactly - i have already prepared the modifications but i still need to fix the payout.
skilled dev. could make it in 30min. i believe, maybe even less - its just me beeing an noob so...

[guugll]

anybody here able to work on p2pool and asking some reasonable bounty for that.

i have done most of the networks.py modifications and used the NVC or YAC p2pool as source.

here is the test pool: http://www.guugll.eu:15327/static/

everythink works except payout... so p2pool gods - how much? and how long?

so anybody interested to help me?

[guugll]

bump

[guugll]

nobody?
just let me know how much - or is it so hard to fix???
 

[meta.p02]

PM'd you. I can try to help.

[guugll]

thx - so we have a move here - will update later.
i think its interesting to move forward with the alt-coins p2pool development.
i will try to look at the PoS + PoS&PoW versions - will see how this will end up - still do not get the PoS+PoW stuff so need to learn a bit more...

still looking for more people to join the forces

thx meta.p02 for cooperation.

i hope more and more p2pool goods will help and stop lafing about my development...
 

[meta.p02]

The error comes from these two lines:

Code:

def _unpack(self, data):
        obj, (data2, pos) = self.read((data, 0))
        
        assert data2 is data
        
        if pos != len(data):
            raise LateEnd()
        
        return obj

def unpack(self, data):
        obj = self._unpack(data)
        
        if p2pool.DEBUG:
            if self._pack(obj) != data:
                raise AssertionError()
        
        return obj

def dataReceiver(self):
        while True:
            start = ''
            while start != self._message_prefix:
                start = (start + (yield 1))[-len(self._message_prefix):]
            
            command = (yield 12).rstrip('\0')
            length, = struct.unpack('<I', (yield 4))
            if length > self._max_payload_length:
                print 'length too large'
                continue
            checksum = yield 4
            payload = yield length
            
            if hashlib.sha256(hashlib.sha256(payload).digest()).digest()[:4] != checksum:
                print 'invalid hash for', self.transport.getPeer().host, repr(command), length, checksum.encode('hex'), hashlib.sha256(hashlib.sha256(payload).digest()).digest()[:4].encode('hex'), payload.encode('hex')
                self.badPeerHappened()
                continue
            
            type_ = getattr(self, 'message_' + command, None)
            if type_ is None:
                if p2pool.DEBUG:
                    print 'no type for', repr(command)
                continue
            
            try:
                self.packetReceived(command, type_.unpack(payload))
            except:
                print 'RECV', command, payload[:100].encode('hex') + ('...' if len(payload) > 100 else '')
                log.err(None, 'Error handling message: (see RECV line)')
                self.transport.loseConnection()

I'm not very familiar with Python, but what this appears to do is to check that read() consumes all the data. What data is the payload?  Also: type_ is getattr(self,'message_tx',None). What is the definition of message_tx?

[guugll]

ok so i wrote you an PM how to make this faster because now i do not have that error and it still does not payout.

if any p2pool gods or python gods see this and would like to help us just PM or write here and we can move on together - now its just me and meta.002

[guugll]

still working on this one - having correct transactions made by the pool but still no payout.
