Running the code:

• python3 main.py <test input file>
  (Ex: python3 main.py testcase.txt)

Building Testcase file:

• testcase file will contain a list of commands with a command in each line.
• each command will have its commandName first, followed by its parameters.
• An example testcase file is included with the project testcase.txt.
• Commands implemented and their format with examples below:
  • Creating/Adding a new node:
    addNode <node_name> <node_id>
    • Ex: addNode n1 30
  • Joining a node to DHT:
    join <new_node_name> <existing_node_name>
    • Ex: join n1 n0
  • pretty print fingerTable of a node:
    ppf <node_name>
    • Ex: ppf n0
  • insert key into DHT from a given node:
    insert <node_name>
    • Ex: insert n0 3 3
  • pretty print key value pairs stored in a node:
    ppk <node_name>
    • Ex: ppk n0
  • look up all keys from a given node:
    lookupall <node_name>
    • Ex: lookupall n2
  • leave a node from DHT:
    leave <node_name>
    • Ex: leave n1
  • find value of a key from a given node
    find <node_name>
    • Ex: find n0 3
  • remove a key from DHT from a given node
    remove <node_name>
    • Ex: remove n1 3

Files:

• main.py -> main file which needs to executed
• utils.py -> interface for commands in testcase to functionality in node objects.
• node.py -> contains class Node and its methods involved.
• fingerTable.py -> contains class fingerTable and its methods.
