populus's Issues

Solidity Compiler Tests fail in platforms other than Mac OS X

Hi,

When I attempt to run the unit tests via tox in a Debian-based host, the solidity compiler tests fail because my solc compiler has a slightly different version number and library references. Please see the attached log.

py_tox_test_06DEC2015.txt

Solc Unit Tests Fail in Ubuntu

The unit tests related to the solc compilation fail due to a version number issue of the solc compiler in Ubuntu vs Mac OS X.

Please see the tox log here:
build-log.txt

Steal the migrations concept from Truffle

While populus deploy is reasonably helpful, I think that populus should move forward by deprecating the deploy command in favor of procedural migration scripts.

Make TODO ethereum app tutorial in docs

The docs should contain a tutorial. Probably a todo app.

pytest fixture accounts does not work

Populus Version: 0.8.0
OS: linux
py-ethereum Version: 1.3.6

What was wrong?

When trying to use accounts, I get the following error:

>   return tuple("0x" + tester.encode_hex(account) for account in tester.accounts)
E   AttributeError: 'module' object has no attribute 'encode_hex'

This is caused by interface changes in pyethereum. encode_hex should be imported from ethereum.utils.

I would gladly provide a PR to fix this.

I got no issue to do a little mkdir libraries but it would be simpler imho to create it with the init command.

Write chain class for externally running chain

Currently all of the populus.chain.Chain classes manage their own blockchains. We need one that represents someone running their own blockchain separately from populus.

Implement populus.chain.ChainProxy that just acts as a container for the chain properties that the rest of populus expects.
Write a helper in populus.utils.cli that does an interactive prompt to configure that chain.
Figure out a way to embed these in the populus.ini file so that people can use them like normal chains.

Populus 1.0.0 refactor changes. Request for Feedback

Introduction

I am currently working on a major revamp of the populus library. Below is a list that I will continue to update as my work progresses. I'm very interested in any feedback on these changes as many of them are going to be breaking changes.

This refactor will also mark the beginning of the 1.x.x line of releases. After this, any breaking changes to public API's will go through a deprecation process (to be determined).

Changes

Remove populus web command.
Switch to py-solc package for solidity compilation
Switch to py-geth for running geth nodes.
Switch to web3.py for all blockchain interactions.
Remove filtering from populus compile command.
populus compile command now runs with --optimize enabled by default.
Deprecate <project-dir>/libraries directory in favor of all source files being located in a single <project-dir>/contracts directory.

Details and Explanations

Switch to `web3.py`

The web3.py interface for working with contracts is compliant with the web3.js interface which is well documented. This should be an overall win for making use of populus easier for new adopters.

This change will break all uses of the populus.contracts.Contract objects as well as all uses of the blockchain_client. I recognize this is significant but I feel strongly this is the right way to go.

If I manually install the ethereum-ipc/rpc-client packages with pip, everything works fine. It does not seem to matter whether I use virtualenv or not. It seems that it is downloading the any package which is a binary distribution from macosx, and then attempts to run the "setup.py" method like it were a source package.

This was working fine in the 0.6.5 version, but has stopped working now.

Implement `Project` object abstraction

What was wrong?

In the pre 1.0.0 versions of populus there was a command populus attach that loaded the user into a python shell with their compiled contracts pre-loaded into the context. This was removed because of the fragility of the feature and inability to handle the maintenance overhead.

The removal of this feature has left a gap, which is easy access to things like the compiled contracts, a web3 instance, and the web3.eth.contract objects.

The proposed way to fix this would be as follows.

>>> from populus.project import default_project as my_project, Project
>>> my_project
<Project at "/path/to/my-project/">  # this would be automatically created an linked to `os.getcwd()`
>>> Project(project_dir="/path/to/some-other-project")
<Project at "/path/to/some-other-project">  # or you can instantiate your own instance if the root project directory is located elsewhere.
>>> my_project.web3  # this would somehow be auto-configured with a test chain or something like that.
>>> my_project.compiled_contracts  # All of the compiled contract data from your project.
{
    "MyContract": {
        "code": "0x...",
        "code_runtime": "0x...",
        "abi": "[...]",
    }
}
>>> contract_factories = project.contract_factories
>>> MyContract = contract_factories.MyContract
>>> MyContract
<web3.contracts.Contract object>
>>> MyContract.deploy()
"0x...."  # The deploy transaction from this contract factory.

This is all just in the idea phase. Feedback welcome. Please let me know any ways that you think this could be improved.

Granular control over deployment

This should support both the eth-testrpc server and the test chains managed by populus chain

Missing dependencies etc.

#1 the package actually depends on python-dev, solc (solidity compiler), and before installing you must install pip itself, and then pip install -r requirements.txt
#2 when solc is missing, the error message is totally non-human (something about subprocess.py execute_child and a messy stack-trace.

webserver and the rpccorsdomain flag

Populus Version: 0.7.5
OS: debian

What was wrong?

I was testing the populus web run command.
I spent some time wondering why I couldn't interact with the web3 instance, only to realize the populus chain run doesn’t pass args for the the rpccorsdomain flag.
is my diagnostic correct ?
That would be a good improvment :) I know the web command is very beta, but still that would be cool :)

Cute Animal Picture

deploy, can I pass arguments ?

Suppose I have a contract with some parameters that can be passed in the constructor, how am I suppose to pass them within the framework ?
I posted on http://ethereum.stackexchange.com/questions/2937/populus-how-do-i-deploy-a-contract-with-args-in-the-constructor as well, sorry if this is not the place on github but maybe someone may have the same interrogation one day and look here... dunno ;)

Scripts feature

What was wrong?

Concept for a new feature that sits somewhere in the middle of deploy and migrate. These would be pre-written scripts that can be executed from the command line. They are provided with full access to the project/chain/web3 objects as necessary. The idea is that there are programatic things that the user may want to do like querying for event logs. One prime example use case is the logic contained in ethereum-alarm-clock-client. Ideally, that entire codebase would become a script within the ethereum-alarm-clock codebase.

Access to project, chain, and web3 objects.
API for adding command line arguments so that scripts can be parametrized.

Support for LLL compilation.

Pluggable chain backends

Implement a backend system for the geth related stuff. This will allow for pluggable backends like parity or cpp-ethereum.

This abstraction already partially exists in the populus.chain.Chain class

Spurious BlockGasLimitReached exceptions while testing

Populus Version: 0.8.0
OS: Ubuntu
deploy_client_type: 'ethtester' (the default)

What's wrong?

During test runs, some Function.s() calls will fail as follows:

Traceback (most recent call last):
  […]
  File "[…]/python2.7/site-packages/populus/contracts/functions.py", line 64, in s
    txn_hash = self(*args, **kwargs)
  File "[…]/python2.7/site-packages/populus/contracts/functions.py", line 58, in __call__
    return self.sendTransaction(*args, **kwargs)
  File "[…]/python2.7/site-packages/populus/contracts/functions.py", line 88, in sendTransaction
    **kwargs
  File "[…]/python2.7/site-packages/populus/ethtester_client.py", line 220, in send_transaction
    raise result
BlockGasLimitReached: <Transaction(c400)>: 'gaslimit' actual:6283184 target:3141592

(The failing call in question is not big, and nowhere near the block limit in terms of gas usage.)

Diagnosis

I suspected that the problem is due to the test VM's blocks not being mined frequently enough, causing transactions to pile up in some circumstances until the limit is hit. Inserting an evm.mine() call in front of the failing transaction prevents the problem, and seems to confirm this hypothesis.

I haven't been able to diagnose the exact cause leading up to the BlockGasLimitReached failures, but I implemented a quick hacky fix in 142070f: this modifies populus.ethtester_client.EthTesterClient to simply perform a mine() before each transaction as well as after, which may be overkill, but seems to prevent the problem so far.

Cute Animal Picture

Runserver command needs an RPC server.

Currently the runserver command doesn't spin up an RPC server. It should.

Document the module level configuration for fixtures better

The documentation for the pytest fixtures is mediocre. It needs to be improved with examples.

Expand the supported contract return values

Currently, a contract function that returns anything other than an int256 or uint256 will throw an error.

Simply need to flesh out populus.contracts.decode_single

Crazy Ideas

Brainstorming Tickets

`populus install ...`

For installing contracts for use as library code.

More granular control over contract compilation and deployment

Currently the CLI interface just compiles/deployes all contracts. There needs to be better control for which contracts to compile/deploy.

Nice Error Messages

The commands that wrap subprocess stuff should produce nice error messages when the binary isn't present on the machine

geth
solc

Documentation for Chains

Write documentation for both the command $ populus chain run and the populus.chain.Chain objects that you can use programatically in your code.

Local test chains
Pre-configured mainnet and morden chains.
Using chains from code via project.get_chain('...')
The properties that the populus.chain.Chain object exposes.

5 test fail because of the same code

populus test : Error: No such command "test".

Populus Version: 0.8.0
OS: linux

is it available ?

Update othe parts of the project to use the `populus.project.Project` interface.

What was wrong?

The populus.project.Project object presents a friendly way to get at many different things from a project (compiled contracts, contract factories, directories, etc)

This interface is not really being used by most of the codebase.

Places that could benefit most from using this:

All of the CLI commands populus.cli.*
The pytest fixtures. populus.plugin

Make populus compile to accept input and output folders

What was wrong?

Currently populus compile makes assumptions about directory layout. It doesn't allow to set build folder target.

I want to use the following deployment model

populus compile to build .sol source
python setup.py sdist to package my app
Install application in its runtime environment
On the application run-time, access contracts.json using Python pkg_resources mechanism
However contracts.json folder is generated in the current project root, not inside my package namespace where I'd like to place it for sdist. This is naturally easy to move. I am not sure if this workflow is correct, just double checking here before suggesting a patch.

Abstract the Migration registrar into a pluggable backend

What was wrong?

The current implementation of migrations uses a Registrar contract to keep track of migration data. Some users will not like the added gas overhead of writing this data to the blockchain.

Possible solution is to abstract this into a generic API so that alternative backends can be written for things like LevelDB.

populus chain run fails with latest geth 1.5.0

Populus Version: 0.8.0
OS: Ubuntu 16.04
Geth: 1.5.0-unstable (current version from Ubuntu Repository)

What was wrong?

populus chain run fails with

Command 'nice -n 20 geth --genesis /usr/local/lib/python2.7/dist-packages/populus/genesis-test.json [...]' returned non-zero exit status 1

running the generated geth command manually returns

flag provided but not defined: -genesis

So apparently the "--genesis" flag was removed from geth.

Support for Mutan compilation

Documentation for pytest fixtures

All of the fixtures found in populus.plugin need to have documentation written for them in docs/testing.rst and docs/fixtures.rst.

Implement `contract_dirs` (plural)

Currently populous only looks in one single directory for contracts. This is dumb. You should be able to have a bunch of directories.

Add ability to configure contract_dirs and convert populus to search all of the provided directories.
Make it so that you can configure this in your populus.ini

Support for serpent compilation

Support compilation of serpant.

Implicit gevent.monkey.patch_all() considered harmful

What was wrong?

There is an implicit import time gevent.monkey.patch_all() in populus.__init__.

This is harmful as it might break other libraries within the same Python process, as gevent gives pretty invasive treatment to Python stdlib. Thus, mere action of importing Populus might break your software in subtle ways.

zopefoundation/transaction#21

If gevent event loop and monkey patching is required, I'd suggest to have an explicit init method that the user needs to call.

gas limit reached issues

Hi,

So I've been playing with your framework some. I've been banging my head against the wall trying to get a very simple contract to run for days. I've finally figured out how to get it work, and I think it may be because you have a very subtle bug in the default contract function "sendTransaction" method.

On line 62 of the file populus/contracts/function.py, you set the default 'gas' value if no 'gas' parameter is passed in the keyword arguments. You use the "get_max_gas" method which pulls the current gasLimit value from the running geth test chain. In my geth test chain, the "gasLimit" value seems to continuously decline all the time. I don't know why the gasLimit is constantly declining, but it seems to decline after every block.

The issue seems to be that by the time my transaction gets submitted to my test chain, the gasLimit value has declined below the "gas" value that is submitted with the transaction. The geth chain seems to then reject this transaction because it has exceeded the gasLimit.

Do you observe this behavior? To fix it, I've actually just divided the "get_max_gas" response by 2 and now all my transactions seem to go through perfectly. I realize this isn't a great way to do this. I'm thinking that using the 'solc' compiler's '--gas' option might be a better way to get estimates of the transaction gas requirement. Thoughts?

(As a side note, the VM rejecting transactions when the gas value is greater than gasLimit doesn't make any sense to me. It would seem to me that the more appropriate response, would be use a min function on the VM's gasLimit and the gas value sent in the transaction. Then, if the method would require more gas than the min of these two values, then the transaction should fail, not fail outright even for small low actual gas transactions. Do you have any idea why the geth transaction processing is implemented this way?)

populus deploy and populus chain run return "subprocess.CalledProcessError: Command returned non-zero exit status 1"

Extract the RPC client

The JSON RPC client should be it's own library.

Allow overriding `Project` properties with config file settings.

The Project class should allow overriding all of its various properties and methods from the populus.ini file.

Documentation for Deploy

All of the documentation for populus deploy needs to be updated in docs/deploy.rst

AttributeError: 'MyContractTest' object has no attribute '_address'

Populus Version: 0.8.0
OS: linux

What was wrong?

I'm trying to use populus in a flask app, "loading" the contracts and got this error, maybe the error is related to a misuse of the framework dunno, but if not I got a simple fix pushed on my fork :

  File "/home/lotso/PycharmProjects/populus/populus/contracts/core.py", line 24, in __str__
    return "{name}({address})".format(name=self.__class__.__name__, address=self._address)

this is how I try to get the contract

@app.route('/index')
def index():
    try:
        client = Client('127.0.0.1', '8545')
        project_dir = os.path.abspath('/home/lotso/PycharmProjects/')
        contracts_meta = utils.load_contracts(project_dir)
        context = {
            'contracts': package_contracts(contracts_meta),
            'client': client,
        }
        contracts = context['contracts']
        contract = contracts.MyContractTest(CONTRACT_ADDRESS, client)
        e = None
    except:
        pass

return render_template('index.html', client=contract)

Python 3 support

This is to track what's needed to make Populus run on Python 3.

At least the following should be needed:

Finish extracting ethereum-contract and ethereum-tester-client (#78)
Conditional imports, such as Queue / queue
String typing (str / bytes)

Python 3 support in upstream dependencies:

pyethereum (ethereum/pyethereum#132), or ethereum-abi-utils (ethereum/eth-abi#1)
ethereum-contract (pipermerriam/ethereum-contract#2)
ethereum-tester-client (pipermerriam/ethereum-tester-client#2)

Package, Publish/Release, and Install Feature

What was wrong?

The migrations functionality opens up a path for populus to evolve into a full ethereum package manager. This idea isn't fully baked but it would look something like the following.

$ populus install 0xd3cda913deb6f67967b99d67acdfa1712c293601/math-utils
$ populus install pipermerriam/math-utils
$ populus install 0xd3cda913deb6f67967b99d67acdfa1712c293601
$ populus release

TODO: flesh this out conceptually.

The following should be loosely defined or thought about.

IPFS integration is neat but ultimately, a URI is all that matters.
Releases can probably contain many combinations of things like ABI, code, runtime, deployed addresses, URIs to source code, digital signatures.

Documentation for Migrations

Documentation for migrations needs to be written.

Overview for what problem migrations try to solve.
How to generate a migration (populus makemigration my_migration_name)
How to initialize a chain for migrations (populus migrate init)
How to run migrations (populus migrate)
Available migration operations (see populus.migrations.operations)
About the Registrar contract (see populus.migrations.registrar)
What values are written to the registrar for each migration.
How to retrieve values from the registrar in your migrations (see populus.migrations.deferred.RegistrarValue and related subclasses)
How to link your contract libraries.

Event/Log Tracking

How are you managing events/log outputs with this framework? I'm thinking that a sub-command called "eventlog" could be useful:

$> populus eventlog --contract MyContract
{MyContract{0xbb348...}, topic=MyDummyEvent, data=["I generated an event"]}
{MyContract{0xbb348...}, topic=MyDummyEvent, data=["I generated another event"]}

As shown, eventlog command would start a new filter via RPC call and check for changes from the running geth chain. The user could pass a set of filters to this command so that only the events that they want to see would be printed out. With the above incantation, the "--contract" filter would allow this sub-command to only print event logs from the "MyContract" contract. Other filters would including the contract specific address, the topic itself (ie, what event name generated this), and possibly a filter on the data content. This is obviously not an exhaustive list.

The user would launch this in a separate terminal, similar to the attach vs chain commands.

The output above obviously is just an example, but it would show the contract, the address, the topic, and data for that particular event generation. I'm think that the user would be able to pass a format string (or reference a file with the appropriate config) that would determine what gets printed out. Alternatively, we could just print everything and expect the user to use sed or awk.

Thoughts? Do you have anything in the works for this or no ?

failures when running tests

I ran the tests and got some failures having to do with starting geth nodes.

Support contract Events

currently events are not implemented at all. They need to be.
