pyethapp's Introduction

pyethapp

https://readthedocs.org/projects/pyethapp/badge/?version=latest

Deprecation notice

Pyethapp is officially deprecated. If you want to run a mainnet node, we recommend using either Geth or Parity. If you want to use Python to develop tooling or interact with the Ethereum ecosystem, we recommend that you shift you attention to Trinity which is based on py-evm.

Pyethapp will no longer receive updates.

Introduction

pyethapp is the python based client implementing the Ethereum cryptoeconomic state machine.

Ethereum as a platform is focused on enabling people to build new ideas using blockchain technology.

The python implementation aims to provide an easily hackable and extendable codebase.

pyethapp leverages two ethereum core components to implement the client:

pyethereum - the core library, featuring the blockchain, the ethereum virtual machine, mining
pydevp2p - the p2p networking library, featuring node discovery for and transport of multiple services over multiplexed and encrypted connections

Installation

Notes

Pyethapp runs on Python 2.7. If you don't know how to install an up-to-date version of Python, have a look here. It is always advised to install system-dependecies with the help of a package manager (e.g. homebrew on Mac OS X or apt-get on Debian).

Please install a virtualenv environment for a comfortable Pyethapp installation. Also, it is always recommended to use it in combination with the virtualenvwrapper extension.

The Homestead-ready version of Pyethapp is v1.2.0.

Installation on Ubuntu/Debian

First install the system-dependecies for a successful build of the Python packages:

$ apt-get install build-essential automake pkg-config libtool libffi-dev libgmp-dev

Installation of Pyethapp and it's dependent Python packages via PyPI:

($ mkvirtualenv pyethapp)
$ pip install pyethapp

Installation on OS X

(More detailed instructions can be found in the Mac OS X installation instructions)

First install the system-dependecies for a successful build of the Python packages:

$ brew install automake libtool pkg-config libffi gmp openssl

Installation of Pyethapp and it's dependent Python packages via PyPI:

($ mkvirtualenv pyethapp)
$ pip install pyethapp

Development version

If you want to install the newest version of the client for development purposes, you have to clone it directly from GitHub.

First install the system dependencies according to your Operating System above, then:

($ mkvirtualenv pyethapp)
$ git clone https://github.com/ethereum/pyethapp
$ cd pyethapp
$ USE_PYETHEREUM_DEVELOP=1 python setup.py develop

This has the advantage that inside of Python's lib/python2.7/site-packages there is a direct link to your directory of Pyethapp's source code. Therefore, changes in the code will have immediate effect on the pyethapp command in your terminal.

Connecting to the network

If you type in the terminal:

$ pyethapp

will show you all available commands and options of the client.

To get started, type:

($ workon pyethapp)
$ pyethapp account new

This creates a new account and generates the private key. The key-file is locked with the password that you entered and they are stored in the /keystore directory. You can't unlock the file without the password and there is no way to recover a lost one. Do not delete the key-files, if you still want to be able to access Ether and Contracts associated with that account.

To connect to the live Ethereum network, type:

($ workon pyethapp)
$ pyethapp run

This establishes the connection to Ethereum's p2p-network and downloads the whole blockchain on the first invocation.

For additional documentation how to use the client, have a look at the Wiki.

Data directory:

When running the client without specifying a data-directory, the blockchain-data and the keystore-folder will be saved in a default directory, depending on your Operating System.

on Mac OS X:

~/Library/Application\ Support/pyethapp

on Linux:

~/.config/pyethapp

This folder also holds the config.yaml file, in which you can modify your default configuration parameters.

To provide a different data-directory, e.g. for additionally syncing to the testnet, run the client with the -d <dir> / --data-dir <dir> argument.

Available Networks

Live (Frontier / Homestead)
Test (Morden)

Currently there are two official networks available. The "Live Network" is called Frontier (soon to be Homestead) and this is what the client will connect to if you start it without any additional options.

Additionally there is the official test network called Morden which can be used to test new code or otherwise experiment without having to risk real money. Use the --profile command line option to select the test network:

$ pyethapp --profile testnet run

Note

If you've previously connected to the live network you will also need to specify a new data directory by using the --data-dir option.

Interacting

You can interact with the client using the JSONRPC api or directly on the console.

Status

Working PoC9 prototype
interoperable with the go and cpp clients

pyethapp's Issues

Allow network_id to be set by config.yaml

In order to set network_id in current code one has to change his default value (0) in eth_protocol.py. May you please allow this important parameter to be set by config.yaml?

Gracefully handle wrong command line options

Currently wrong parametrization is mostly catched by asserts, which raise an AssertionError instead of a helpful error message.

Task:

Identify possibilities of wrong parametrization
Identify the asserts raised
Change these asserts to raised Exceptions with identifiable names
Catch these exceptions on startup and report a meaningful error message

Missing module

I am getting an error of missing module 'canary' after simple invoking 'pyethapp'. The error log is:

This package cannot be safely installed by EasyInstall, and may not

I was able to get around it by manually running pip install pbkdf2 and then python setup.py install

Readability of Exception: Database, network_id

For better understanding of the issue:

"Exception: This database was initialized with network_id 2 and can not be used when connecting to network_id 1"

"Exception: This database was initialized with network_id 2 and can not be used when connecting to network_id 1. Choose different datadir."

New blocks + genesis handling broke jsonrpc tests

@jnnk
b50e9da

i didn't take a closer look, but it seems that there are no funds to send txs (maybe need to add some alloc to the genesis). event tests stall if the tx fails.

Geth / pyethapp interoperability flaws

I'm trying to get pyethapp to play nice with geth. Pyethapp is on a virtual machine, both on a private network with custom genesis block. As soon as geth starts mining, pyethapp complains about "Block's difficulty is inconsistent with its parent's difficulty". Any ideas?

Documentation: Installation, py-scrypt failed

Just further documenting the installation and invocation process I'm having

When using: pyethapp run I got the following warning:

Failed to import scrypt. This is not a fatal error but does mean that you cannot create or decrypt privkey jsons that use scrypt

To fix it I tried to install the following, BUT DID NOT SOLVE THE WARNING:

$ sudo apt-get install mercurial
$ hg clone http://bitbucket.org/mhallin/py-scrypt
$ cd py-scrypt
$ python setup.py build
Become superuser (or use virtualenv):
$ python setup.py install
Run tests after install:
$ python setup.py test

Greacefully handle Empty Datadir

users tend to create the datadir instead of relying on creation by the app.
app fails if the datadir exists but has no config yet. reported by multiple users.

How to install required dependencies? (not a python user here)

Readme:

$ git clone https://github.com/ethereum/pyethapp
$ cd pyethapp
$ python setup.py install

Output:

Traceback (most recent call last):
  File "setup.py", line 5, in <module>
    from setuptools import setup
ImportError: No module named setuptools

I tried:

sudo easy_install setuptools
pip install setuptools
Requirement already satisfied (use --upgrade to upgrade): setuptools in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python

I'm not a Python guy but decided to try Python client because:

If you are interested in understanding how ethereum works and how to extend it, the code base of this client is probably the most readable and has a great contract tester library with fast development cycles.

Would be nice if I could run it without messing with dependencies.

SPV over webRTC

from discussion with Heiko;
It would be awesome to have a SPV client running purely in the browser. What is need to support this is

bridge nodes, browser can't talk TCP. instead we can use WebRTC. But we need bridge nodes to the "real" network
we need SPV protocol. Which i think python has implemented
the full eth subprotocol must be supported over WebRTC. But depending on the network traffic light clients don't want to know about all the new txs and new blocks. so maybe there should be some way to only selectivly get new txs and block

Genesis Configuration

handling in app.py

ideally integrates with the config file, default_config and -c option we have.
maybe add support to load configurations for a certain config namespace only e.g.
--load_config=eth.genesis:/path/to/config
default configs for frontier and olympic should be supported by cmd line options
check with db if genesis matches
load genesis block only if there is none in the db

handling in ethereum.blocks.py:

there should be a default_config and a config property in the module
external updates to the config can be made by updating setting config
json with hex encoded should be decoded to py types when loaded (type map), mot in blocks.py

how it could look like in blocks.py

default_config = AttrDict()
default_config.GASLIMIT_EMA_FACTOR = 1024 
default_config.GASLIMIT_ADJMAX_FACTOR = 1024 
default_config.genesis = AttrDict()
default_config.genesis.PREVHASH = b'\x00' * 32
default_config.genesis.COINBASE = b'\x00' * 20
config = deepcopy(default_config) # somehow

make sure none of these is set/used somewhere else on module load.

external modules should be able to set a new config.

Distribution misses genesis data files

ethash requirements during install

I was unable to sync the chain until cloning https://github.com/ethereum/ethash and then installing ethash with python setup.py install. Should these steps be mentioned in the readme?

Numerous errors after a fresh pyethapp install

After installing pyethapp on my machine for the first time I received a couple of errors. As I am new to pyethereum I may have made an installation error.

I use Mac OS X 10.10.4 with Python 2.7.10 in a virtualenv.

At least one of those errors was already reported elsewhere (e.g. ethereum/pyethereum#259 TypeError: function takes exactly 2 arguments (1 given)) so I won't repeat it. After this error a couple more errors occurred:

Apart from calling the executable which does not work in travis-ci context:

coinbase but no accounts is confusing

pyethapp/v1.0.1

It is confusing that there are no accounts, when a coinbase exists. For consistency with other clients, the coinbase should be included as the first account.

Looks like the call signature for mkcache may have changed. I had trouble introspecting pyethash but it all appears to be c libraries.

Load custom services from config folder

Load modules found in configdir/contrib on startup. If modules implement a BaseService they should add it to pyethapp.app.services in order to get initialized on startup.

This was started before, non working code can be found here:

jsonrpc: error objects

looks like we don't return proper errors yet. e.g. when not finding a filter.

[11.06.15 15:08:58] there is also some proposal, regarding errors:

[11.06.15 15:09:23] it's not yet implemented in cpp, but I think that go supports most of this errors

Documentation: Installation, c_secp256k1

When using: pyethapp run I got the following warning:

UserWarning: could not import c_secp256k1, fallback to bitcointools warnings.warn('could not import c_secp256k1, fallback to bitcointools')

To fix it I had to install:
// Download c_secp256k1
git clone https://github.com/czepluch/pysecp256k1.git
cd pysecp256k1

// Dependencies for c_secp256k1
sudo apt-get install libssl-dev
sudo apt-get install libffi-dev
sudo apt-get install libtool

// Set-up c_secp256k1
sudo python setup.py install

pypy3 support

The major challenge with py3 is to keep the code base clean.
The major challenge with pypy is that some c-module won't work and we'll either have to find a substitute or develop our own bindings.

For reference:
ethereum/pyethereum#132
ethereum/pyethereum#188

note: miniupnpc isn't used anymore.

for pypy3 we need gevent 1.1, currently it breaks neworking:
ethereum/pydevp2p#2

sha3 replacement:
