报错信息提示WTMSIG_BLOCK_SIGNATURES
查看合约更新日志
https://github.com/EOSIO/eosio.contracts/releases/tag/v1.9.1

The eosio.system and eosio.bios contracts contained in this release can only be deployed on an EOSIO blockchain after the activation of the WTMSIG_BLOCK_SIGNATURES consensus protocol upgrade.

只有开启WTMSIG_BLOCK_SIGNATURES共识才能使用此合约。
根据查看 https://github.com/EOSIO/eos/pull/7404

开启WTMSIG_BLOCK_SIGNATURES共识

目前开启WTMSIG_BLOCK_SIGNATURES共识,需要系统账户先部署eosio.boot,并且此合约在单独的合约分支(吐槽下EOSIO代码版本管理...)
先获取下add-boot-contract分支合约

git clone --branch add-boot-contract https://github.com/EOSIO/eosio.contracts.git
./[path]/eosio.contracts/build.sh

和之前部署一样先激活PREACTIVATE_FEATURE

curl -X POST http://127.0.0.1:8888/v1/producer/schedule_protocol_feature_activations -d '{"protocol_features_to_activate": ["0ec7e080177b2c02b278d5088611686b49d739925a92d9bfcacd7fc6b74053bd"]}' | jq

然后部署下eosio.boot合约

cleos set contract eosio [path]/eosio.contracts/build/contracts/eosio.boot -p eosio@active

激活WTMSIG_BLOCK_SIGNATURES协议

cleos -u http://127.0.0.1:8888 push transaction '{"delay_sec":0,"max_cpu_usage_ms":0,"actions":[{"account":"eosio","name":"activate","data":{"feature_digest":"299dcb6af692324b899b39f16d5a530a33062804e41f09dc97e9f156b4476707"},"authorization":[{"actor":"eosio","permission":"active"}]}]}'

最后查询下PREACTIVATE_FEATUREWTMSIG_BLOCK_SIGNATURES是否已成功激活

curl -X POST http://127.0.0.1:8888/v1/chain/get_activated_protocol_features -d '{}' | jq
{
  "activated_protocol_features": [
    {
      "feature_digest": "0ec7e080177b2c02b278d5088611686b49d739925a92d9bfcacd7fc6b74053bd",
      "activation_ordinal": 0,
      "activation_block_num": 1176,
      "description_digest": "64fe7df32e9b86be2b296b3f81dfd527f84e82b98e363bc97e40bc7a83733310",
      "dependencies": [],
      "protocol_feature_type": "builtin",
      "specification": [
        {
          "name": "builtin_feature_codename",
          "value": "PREACTIVATE_FEATURE"
        }
      ]
    },
    {
      "feature_digest": "299dcb6af692324b899b39f16d5a530a33062804e41f09dc97e9f156b4476707",
      "activation_ordinal": 1,
      "activation_block_num": 12770,
      "description_digest": "ab76031cad7a457f4fd5f5fca97a3f03b8a635278e0416f77dcc91eb99a48e10",
      "dependencies": [],
      "protocol_feature_type": "builtin",
      "specification": [
        {
          "name": "builtin_feature_codename",
          "value": "WTMSIG_BLOCK_SIGNATURES"
        }
      ]
    }
  ]
}

然后继续之前的步骤,继续部署eosio.bios合约,以及后面的步骤

cleos set contract eosio contracts/eosio.bios

EOS v2.0.x 打deb 包

测试系统

os: ubuntu 18.04 server
eos: v2.0.1

打包

编译完EOS后,切换到打包脚本目录

./scripts/eosio_build.sh -s EOS
cd ./build/packages

并执行打包操作

./generate_package.sh deb

如果是WSL 打包的话会报

dpkg-deb: error: control directory has bad permissions 777 (must be >=0755 and <=0775)

报错是因为当前打包的目录权限为777,需要修改为 0755到0775之间的某个权限。
由于WSL 默认是没有开启chmod的,所以需要先开启,才能修改目录权限。

WSL 启用chmod

新建配置文件

sudo vi /etc/wsl.conf

内容如下

[automount]
enabled = true
root = /mnt/
options = "metadata"

关闭所有bash,重新打开即可。

修改打包目录权限

chmod 775 eosio/* -R

再次执行打包即可

./generate_package.sh deb

EOS合约内判断账户是否部署了合约

根据社区小伙伴需求,需要合约内查看某账户是否部署了合约,
我们根据setabi action,看下系统合约代码
https://github.com/EOSIO/eosio.contracts/blob/636406b45a4e1d4c3d7b308f6064dfe61b962814/contracts/eosio.system/src/eosio.system.cpp#L361

  void native::setabi( const name& acnt, const std::vector<char>& abi ) {
      eosio::multi_index< "abihash"_n, abi_hash >  table(get_self(), get_self().value);
      auto itr = table.find( acnt.value );
      if( itr == table.end() ) {
         table.emplace( acnt, [&]( auto& row ) {
            row.owner = acnt;
            row.hash = eosio::sha256(const_cast<char*>(abi.data()), abi.size());
         });
      } else {
         table.modify( itr, same_payer, [&]( auto& row ) {
            row.hash = eosio::sha256(const_cast<char*>(abi.data()), abi.size());
         });
      }
   }

当账户部署合约时,会将合约的hash更新到abihash表,所以我们根据这个表,来判断是否部署了合约就好了

cleos -u https://api.eoslaomao.com get table eosio eosio abihash -L eosio.token -l 1

返回数据

{
  "rows": [{
      "owner": "eosio.token",
      "hash": "85fd4e647e88e595223e69d09a3368a14a45d29320ed1515f54fdfac6ca999df"
    }
  ],
  "more": true
}

当合约账户删除部署合约时,

cleos -u https://api.eoslaomao.com set abi -c

这个hash值为

0000000000000000000000000000000000000000000000000000000000000000
结论

判断下对应账户在该abihash表有记录,且hash值不为0000000000000000000000000000000000000000000000000000000000000000,即为已部署合约。

备注

cleos get code 拿到的是 wasm 和 abi 原数据,然后本地计算的hash(查看源代码),这个一般主要是判断 合约 有没有更新变化用。如果只是判断是否部署合约,还是本文更直接

【Ubuntu】Ubuntu 18.04 LTS 更换国内源——解决终端下载速度慢的问题

最近装了ubuntu18.04 LTS,下载软件有点慢,网上搜了下解决方案,大致是两种:一、把/etc/apt/sources.list文件里的源更换一下,改成阿里云或者其它的镜像的文件;二、更换software&updates里的select best server。

一、更换/etc/apt/sources.list文件里的源

1. 备份源列表

Ubuntu配置的默认源并不是国内的服务器,下载更新软件都比较慢。首先备份源列表文件sources.list:

# 首先备份源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

2. 打开sources.list文件修改

选择合适的源,替换原文件的内容,保存编辑好的文件, 以阿里云更新服务器为例(可以分别测试阿里云、清华、中科大、163源的速度,选择最快的):

# 打开sources.list文件
sudo gedit /etc/apt/sources.list

编辑/etc/apt/sources.list文件, 在文件最前面添加阿里云镜像源:

#  阿里源
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

3. 刷新列表

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential

下载速度瞬间就起飞了。

4. 其他源

中科大源:

WSL 编译EOS报 set: -i: invalid option

windows10 Linux子系统(Ubuntu 18.04)编译EOS报错如下

surou@DESKTOP-444S803:/mnt/c/github/eos$ ./scripts/eosio_build.sh
EOSIO Version: 1.8.6
Sat Jan  4 05:50:58 UTC 2020
User: surou
Current branch: develop
./scripts/eosio_build.sh: line 129: set: -i: invalid option
set: usage: set [-abefhkmnptuvxBCHP] [-o option-name] [--] [arg ...]

原因是子系统的系统名不是Ubuntu

( [[ ! $NAME == "Ubuntu" ]] && [[ ! $ARCH == "Darwin" ]] ) && set -i # Ubuntu doesn't support interactive mode since it uses dash + Some folks are having this issue on Darwin; colors aren't supported yet anyway

查看子系统的Name

surou@DESKTOP-444S803:/mnt/c/github/eos$ echo $NAME
DESKTOP-444S803

所以编译时设置下环境变量即可
编辑环境变量配置文件

vim ~/.bashrc

将下面参数添加到文件尾部

export NAME=Ubuntu
export VERSION_ID=18.04

备注:如果安装1.8.x的EOS,且没配置过环境变量的话,可以一起加上

export PATH=$PATH:/home/surou(当前用户名)/eosio/1.8/bin

然后刷新环境变量

source ~/.bashrc

然后再次执行

surou@DESKTOP-444S803:/mnt/c/github/eos$ ./scripts/eosio_build.sh
