webthree-umbrella's Introduction

Former home of webthree-umbrella (cpp-ethereum)

cpp-ethereum is the Ethereum C++ client.

This repository was an "umbrella" repository which was the home for the various C++ projects betwen October 2015 and August 2016. Prior to that point all the work had happened under a single repository (cpp-ethereum), and that is where all C++ runtime development work has now returned, with solidity now being a standalone repository.

AlethZero, AlethOne and AlethFive have been retired
Mix has been retired
Solidity is now standalone, and development continues in that repo
The restored cpp-ethereum repository is the mainline for the C++ runtime client
- That is a merger of the libethereum, libweb3core, webthree and webthree-helpers repositories

Please do not create pull-requests against this repository. It is no longer in-use.

webthree-umbrella's Issues

VM trace BlockGasLimitReached exception

Moved here from cpp-ethereum

I am trying to get a VM trace for a historical transaction using the admin_eth_vmTrace JSON RPC in eth/cpp-ethereum.

I trigger the call with curl and get no result:

% curl -X POST --data '{"jsonrpc":"2.0","method":"admin_eth_vmTrace","params":["0x8fadc1f1bbfdbdafee19e358cd5e3731cedd871f24be078c3aef071b8c78f470",6,"XXXXXXXXXXX="],"id":1}' http://localhost:8545

{"id":1,"jsonrpc":"2.0","result":null}

I believe that should return a VM trace for the transaction at index six of the block 0x8fadc1f1bbfdbdafee19e358cd5e3731cedd871f24be078c3aef071b8c78f470 (block #237,298, tx 0x87bc16547fe2be8f7e360df63ed1b88ca7a0c8b69cbc400681bc0be0e30761a8). 'XXXXXXXXXXX=' is the JSON RPC admin session key--if incorrect, the RPC returns an 'Invalid privilege' message.

When eth runs the command, it outputs a message like this:

 ✘  15:43:52|  /tmp/cpp-ethereum20150914-80200-1jb1ne0/libethereum/Executive.cpp(196): Throw in function void dev::eth::Executive::initialize(const dev::eth::Transaction &)
Dynamic exception type: boost::exception_detail::clone_impl
std::exception::what: BlockGasLimitReached
[dev::tag_required*] = 5000
[dev::tag_got*] = 21000

The same thing happens with other transactions.

This is an OS X homebrew install with --with-vmtrace. Here is some status/version info:

% curl -X POST --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' http://localhost:8545
{"id":1,"jsonrpc":"2.0","result":"0x3caa5"}

(0x3caa5 = 248,485 > 237,298)

% curl -X POST --data '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":1}' http://localhost:8545

{"id":1,"jsonrpc":"2.0","result":"++eth-v0.9.41-ed7a8a35//Debug-Darwin/clang/int"}

% eth --version

eth version 0.9.41
eth network protocol version: 61
Client database version: 12041
Build: Darwin/clang/int/Debug

The same issue is reported under 0.9.42 here: https://forum.ethereum.org/discussion/3515/vm-trace-blockgaslimitreached-exception .

Blockchain tests refactoring

this one introduce new approach on blockchain tests
and separetes testing and mining logic

Illegal instruction: 4

Moved here from cpp-ethereum

I've compiled eth on my MacBook - but unfortunately it gives the error: "Illegal instruction: 4". Does anyone know how to avoid the problem?

probably should check the Hello protocol version against the subprotocol version (status)

Moved here from cpp-ethereum

tested on Alethzero; it will merry except a non-nonsensical eth subprotocol version number

solidity interface changes. removing get prefix

Mining suddenly stopped

Moved here from cpp-ethereum

While running mining node with 150 workers - node mined few blocks and then stucked, i saw it was generating valid getwork and receiving with submitHashrate, but it couldn't solve block for 12hours, while it's regularly solving at least one block per 1 hour, i thought it was bad luck, but i have reproduced this again.

CUDA mining support

Moved here from cpp-ethereum

I know you guys are busy reorganizing the whole repo, but after you've completed that work, it shouldn't be too difficult to merge this in.

Some work is still needed on copying the right DLLs into the release folder etc. Also untested on Linux.

CUDA implementation of Ethash

Moved here from cpp-ethereum

When linking against extdep OpenCL.lib, my hashrate is almost 10% lower than when I link against NVidia CUDA 7.5RC.

BlockQueue hang forever at stop function

There is a strange bug with BlockQueue which is hard to reproduce.
I got this one when importing over hundred of blocks into blockchain.
It happens ~ 1/10000 blocks imported into chain.

The debugger wont follow into the thread. Trace lead to function BlockQueue::stop
https://github.com/ethereum/libethereum/blob/develop/libethereum/BlockQueue.cpp#L72
verifier threads never join and thus application hang for unlimited time.

Verifier thread code apparently located at https://github.com/ethereum/libethereum/blob/develop/libethereum/BlockQueue.cpp#L97

Ethminer GPU failure handling

Moved here from cpp-ethereum

In multi AMD GPU rig if one GPU fails, ethminer does not produce hashes, but still polling for new work (sometimes it does not poll) and the rest of GPU still running under load and consume energy for nothing.

Rarely if one GPU fails, ethminer continue to run on the rest of GPUs, but failed GPU will never backup. I am wondering if it's possible to fix?

Can't make - llvm errors with new dependencies

Moved here from cpp-ethereum

llvm has a whole new set of dependencies...

Trying to build on Ubuntu 14.04.2 -
cpp build worked great up until last release...
get llvm error when trying to make.

Backing up in instructions, notice there's new prerequisites:
sudo apt-get -y install build-essential git cmake libboost-all-dev libgmp-dev libleveldb-dev libminiupnpc-dev libreadline-dev libncurses5-dev libcurl4-openssl-dev libcryptopp-dev libjson-rpc-cpp-dev libmicrohttpd-dev libjsoncpp-dev libargtable2-dev llvm-3.8-dev libedit-dev mesa-common-dev ocl-icd-libopencl1 opencl-headers libgoogle-perftools-dev qtbase5-dev qt5-default qtdeclarative5-dev libqt5webkit5-dev libqt5webengine5-dev ocl-icd-dev libv8-dev

Try to run above command and get this:
The following packages have unmet dependencies:
llvm-3.8-dev : Depends: libllvm3.8 but it is not going to be installed
Depends: libstdc++6 (>= 4.9) but 4.8.4-2ubuntu114.04 is to be installed
Depends: llvm-3.8 (= 1:3.8svn243996-1~exp1) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Try to manually install any of those and no dice for any of them...

Using any obscure or bleeding edge library dependencies?

Memory usage (Windows) way too high

Moved here from cpp-ethereum

eth.exe/altethzero.exe memory usage is about 1.4GB private bytes (+160M working set) after sync.
Even Bitcoin Core is not that memory hungry.
ethminer.exe is eating 90MB+ private and 1.1GB+ in working set

DAG file generation and update on epoch switch is unreliable

Moved here from cpp-ethereum

I noticed several issues with DAG:

After epoch switch some rigs still mine on old DAG:
Invalid header on mined block: Block's nonce is invalid.
This is very big loss (10% of the rigs are wasting power)
After node restart some rigs suddenly can start DAG regeneration without a reason (node in sync, epoch is the same).
After ethminer restart it can force DAG regeneration without a reason.

// ethminer, Windows rigs

Solution validation in ethminer fails when a new work package arrives and in the meantime a solution for previous package is found

Moved here from cpp-ethereum

The file MinerAux.h in the ethminer project contains the method doFarm. This method sets up a callback that gets called when a new solution is found:

            bool completed = false;
            EthashProofOfWork::Solution solution;
            f.onSolutionFound([&](EthashProofOfWork::Solution sol)
            {
                solution = sol;
                return completed = true;
            });

The inner loop is checking for new work packages and if there is a new work package it changes the current.headerHash, current.seedHash and current.boundary variables:

                if (hh != current.headerHash)
                {
                    current.headerHash = hh;
                    current.seedHash = newSeedHash;
                    current.boundary = h256(fromHex(v[2].asString()), h256::AlignRight);
                    minelog << "Got work package:";
                    minelog << "  Header-hash:" << current.headerHash.hex();
                    minelog << "  Seedhash:" << current.seedHash.hex();
                    minelog << "  Target: " << h256(current.boundary).hex();
                    f.setWork(current);
                }

The inner loop exists once completed is set to true - which happens in the callback. If a new solution is found in the same loop iteration as when a new work package was received the loop exits. The problem is that the solution is checked against the new work package:

            cnote << "Solution found; Submitting to" << _remote << "...";
            cnote << "  Nonce:" << solution.nonce.hex();
            cnote << "  Mixhash:" << solution.mixHash.hex();
            cnote << "  Header-hash:" << current.headerHash.hex();
            cnote << "  Seedhash:" << current.seedHash.hex();
            cnote << "  Target: " << h256(current.boundary).hex();
            cnote << "  Ethash: " << h256(EthashAux::eval(current.seedHash, current.headerHash, solution.nonce).value).hex();
            if (EthashAux::eval(current.seedHash, current.headerHash, solution.nonce).value < current.boundary)
            {
                bool ok = rpc.eth_submitWork("0x" + toString(solution.nonce), "0x" + toString(current.headerHash), "0x" + toString(solution.mixHash));
                if (ok)
                    cnote << "B-) Submitted and accepted.";
                else
                    cwarn << ":-( Not accepted.";
            }
            else
                cwarn << "FAILURE: GPU gave incorrect result!";

Because current.headerHash, current.seedHash and current.boundary were overridden when the new work package arrived the check fails and we get the warning "FAILURE: GPU gave incorrect result!".

Alethzero segfault when deleting web3 directory

Moved here from cpp-ethereum

When I deleted the .web3 directory along with my account, Alethzero segfaulted in this part of the code. Fix should be easy.

Support installing without JIT, thus on 32-bit

Moved here from cpp-ethereum

According to the Ubuntu build page,

The best supported platform as of December 2014 is Ubuntu 14.04, 64 bit, with at least 2 GB RAM

Doesn't appear, in any use of English I'm familiar with, to say that 32-bit is not supported, and I can imagine no reason why ethereum would require any 64-bit functionality, so I optimistically spent a couple of days attempting to build.
I failed.

If anyone has managed in any way to install on 32-bit, please let me know how!

My process was:

git clone https://github.com/ethereum/cpp-ethereum git checkout develop

followed by cmake.

It failed on the llvm 3.8 dependency, but got a little closer after additionally
sudo apt-get install cpp-ethereum

cmake still failed, essentially for the lack of llvm 3.7 / 3.8

I saw a workaround for broken llvm 3.7 /3.8 in evmjit/CMakeLists so I tried git cloning llvm to ~/llvm/build , then

cd ~/cpp-ethereum/ && rm -rf build && mkdir build && cd build cmake .. -DETHASHCL=1 -DOpenCL_INCLUDE_DIR=/usr/include/hwloc -DLLVM_DIR=~/llvm/build/share/llvm/cmake/ make -j2

cmake suceeded, but make failed, giving:
In file included from /home/mimi/llvm/include/llvm/IR/IntrinsicInst.h:30:0, from /home/mimi/cpp-ethereum/evmjit/libevmjit/Arith256.cpp:8: /home/mimi/llvm/include/llvm/IR/Intrinsics.h:40:34: fatal error: llvm/IR/Intrinsics.gen: No such file or directory #include "llvm/IR/Intrinsics.gen" ^ compilation terminated. make[2]: *** [evmjit/libevmjit/CMakeFiles/evmjit.dir/Arith256.cpp.o] Error 1 make[1]: *** [evmjit/libevmjit/CMakeFiles/evmjit.dir/all] Error 2

(apologies for the erratic formatting - this is a digest from paper notes)

Intrinstics.gen appears to be a restating of available number types, but that's way beyond me (anyone with a little experience might say that I'd reached and passed the 'way beyond me' stage earlier than that in any case ;)

So, where are we here?
It seems to me that the build fails on what appears to me to be a not-particularly-necessary dependency on llvm at 3.7 / 3.8, which are not available in any repositories I've found (apart from 64bit ubuntu).
On the other hand, though if I'm right, the root cause is trivial, fixing that problem is way beyond me (I guess it inolves sanitising the C code to make it backwards-compatible?) and it seems strange that there is apparently a whole ethereum ecosystem starting up and that all of those involved have spare 64-bit machines to turn over to testing it, so I'm guessing someone somewhere knows an easy way to install on a 32-bit machine.

My 32-bit machine is going to be dedicated (for now) to ethereum, so I am happy to choose (or complie) the OS to suit,

Fix utcTime() function

Moved here from cpp-ethereum

This PR is for implementing a utcTime() function that does not just use time(0) to return the current UTC timestamp. The reasoning behind this is that according to the documentation

The value returned generally represents the number of seconds since 00:00 hours, Jan 1, 1970 UTC (i.e., the current unix timestamp). Although libraries may use a different representation of time: Portable programs should not use the value returned by this function directly, but always rely on calls to other elements of the standard library to translate them to portable types (such as localtime, gmtime or difftime).

the time(0) function is not guaranteed to return a UTC timestamp, even though in most implementations, as we have seen, it will. Only way to do that seems to be to combine it with gmtime() as we do in this PR.

Alethzero v0.9.92 Key Import Crashes App

Moved here from cpp-ethereum

Importing a secret key file (created in Alethzero v0.9.40) into Alethzero v0.9.92 crashes Alethzero. FYI, I am on Win10...not sure about any other OS. Workaround: importing with v0.9.41 worked fine, then fired up v0.9.92 instead afterwards, and the account showed no obvious issues in v0.9.92.

web3.admin.net.connect() won't be able to add new peers dynamicly

Moved here from cpp-ethereum

Hi all:
Does anybody try to add new peers manually by call web3.admin.net.connect() in ethconsole?
My testing seem it won't work. Does I mis-used it or it's a defect?

the command line I used was :
web3.admin.net.connect("host:port")

the way to confirm if it's connect was
web3.admin.net.peers()

thanks.

Deterministic Addresses

It would be nice if cpp-ethereum supported creating deterministic private keys from a set passphrase.

Maybe BIP 0032 is worth implementing, of course it is important to remember criticisms of such HDM wallet schemes (see Buterin (2013)).

alethzero crashes when you try importing json key made by geth

If trying to import on alethzero an UTC-xxxx json file made by geth, alethzero crashes.

Solved editing the UTC-xxx json file. Just lower case the C of the word: "Crypro", from "Crypto" to "crypto"

Can you fix?

[OS X] boost w/c++11 support not needed

Moved here from cpp-ethereum

Going off of my exploration in #2643:

The default (precompiled) version of boost 1.58 was successfully installed using Homebrew.

I edited the cpp-ethereum brewfile to comment out the c++11 stuff

  depends_on 'boost' # => "c++11"
  depends_on 'boost-python' # => "c++11"

I installed cpp-ethereum using brew install ethereum/ethereum/cpp-ethereum --devel --build-from-source as per the the docs.
I chose not to compile latest version of LLVM for EVMJIT support.

Since compiling boost takes insanely long, and llvm takes insanely longer, this should be unnecessary unless there is no other way around it.

At least ethminer ran fine (after I specified the opencl device, see #2643).

The docs and brewfile should be updated to reflect this. Asking that a custom version of boost be compiled should be removed if it is not necessary (perhaps relegated to an option like --link-boost-c11).
