Market Community cannot be initialized.

[StefanBoodt]

Please, fill all relevant items:

• [ ] I have read CONTRIBUTING.md
• [x] I have tried with the latest pre-release version and I still can reproduce the issue.

  Tribler version/branch+revision:

Tribler feature/market

Operating system and version:

Ubuntu 14.04

Expected behavior:

Tribler community starts.

Actual behavior:

TypeException is thrown.

Steps to reproduce the behavior:

It goes wrong as follows:

from twisted.internet.threads import blockingCallFromThread from Tribler.Core.Utilities.twisted_thread import reactor from Tribler.community.market.community import MarketCommunity

def start_market_community(): """This will start the market community, do not forget to start this in a seperate thread.""" keypair = self.dispersy.crypto.generate_key(u"curve25519") member = self.dispersy.get_member(private_key=self.dispersy.crypto.key_to_bin(keypair)) cls = MarketCommunity self.market_community = self.dispersy.define_auto_load(cls, member, (self.session, self.settings), load=True)[0]

blockingCallFromThread(reactor, start_market_community)

Relevant log file output:

File "ExitNode.py", line 207, in start blockingCallFromThread(reactor, start_market_community) File "/usr/lib/python2.7/dist-packages/twisted/internet/threads.py", line 122, in blockingCallFromThread result.raiseException() File "", line 2, in raiseException TypeError: initialize() takes exactly 1 argument (3 given)

Reason of it going wrong:

Dispersy create community calls initialize with 3 arguments. It specifies initialize as

def initialize(self, _args, *_kwargs) for subclasses.

[mitchellolsthoorn]

That is because you're giving it three arguments, dispersy itself only accepts one (the class). So you should remove the arguments (self.session, self.settings), because the community doesn't use these. We do need the multichain community, so that should be the second argument

[StefanBoodt]

We already started that community. I shall check again.
