kad.py's Issues

Message validator

Implements the ability to inject a validator function for messages. A message is processed only if the validator function return true

Persistent storage fail

Getting keys with persistent storage fails.
Below how to replicate the error

from kad import DHT
import shelve

# bootstrap node
host1, port1 = 'localhost', 3000

# this node
host2, port2 = 'localhost', 3001
dht2 = DHT(host2, port2, seeds=[(host1,port1)], storage=shelve.open ('storage_two.dat'))

print (dht2["file00"])	# blocking get
dht2.get("file00", lambda d: print(d)) # threaded get

  File "two.py", line 12, in <module>
    print (dht2["file00"])	# blocking get
  File "/Users/frag/Documents/kad.py/kad/kad.py", line 199, in __getitem__
    if hashed_key in self.data:
  File "/usr/local/Cellar/python3/3.6.2/Frameworks/Python.framework/Versions/3.6/lib/python3.6/shelve.py", line 102, in __contains__
    return key.encode(self.keyencoding) in self.dict
AttributeError: 'int' object has no attribute 'encode'

Logger

Implement a cool logger to display debug informations about:

  • peer network
  • data requests / handling

Data cache

Offline data cache to restore data after restart

Deletion

Hello,

It's not an issue only two simple questions about things which are not in the documentation.

It's possible to delete a key/value from the DHT ?
Is there an expiration time by default for the key/value ?

Thank you.
