error: "assertion failure with message: system contract must first be initialized"

2019-04-11　 Surou　阅读　 EOS-新手问答　 0 评论

部署完eosio.system后，执行

cleos push action eosio init '[0,"4,SYS"]' -p eosio@active

解决TortoiseGit的pull操作将Unix换行符自动转成dos换行符——$'\r': command not found

2019-04-11　 Surou　阅读　 EOS-新手问答　 0 评论

一些同学想用Windows + sub ubuntu 编译eos,在windows下使用TortoiseGit pull 后，导致sh换行符被默认转换成dos '\r',运行出错。

解决方法

对于git bash用户使用命令：

git config --global core.autocrlf false

为了保证文件的换行符是以安全的方法，避免windows与unix的换行符混用的情况，最好也加上这么一句

git config --global core.safecrlf true

对于使用TortoiseGit的同学来说可以“快捷菜单”->“Git"，将autocrlf去掉勾选

备注

现在的出块顺序是按ascii排序的，理想的是支持heartbeat,按地理位置顺序出块，可减少延迟不稳定等问题

cleos system claimrewards Error 3050003 “quantity exceeds available supply”

2018-11-09　 Surou　阅读　 EOS-新手问答　 0 评论

在测试网中，获取出块奖励时，报错

surou@bcskillsurou:~$ cleos -u http://127.0.0.1:8000 system claimrewards bcskillsurou -p bcskillsurou
Error 3050003: eosio_assert_message assertion failure
Error Details:
assertion failure with message: quantity exceeds available supply
pending console output:

查询supply

surou@bcskillsurou:~$ cleos -u http://127.0.0.1:8000 get currency stats eosio.token EOS
{
  "EOS": {
    "supply": "10000000000.0000 EOS",
    "max_supply": "10000000000.0000 EOS",
    "issuer": "eosio"
  }
}

发现supply已经不小于max_supply。
由于bp每次claimrewards时，根据距离上次claim的时间差先增发，然后再从奖池里面拿。所以每次claimrewards时，supply都会增加相应的值，但必须小于max_supply。
继续跟进

创建代币
cleos -u http://127.0.0.1:8000 push action eosio.token create '["eosio","10000000000.0000 EOS",0,0,0]' -p eosio.token
发布代币
cleos -u http://127.0.0.1:8000 push action eosio.token issue '["eosio","10000000000.0000 EOS","issue"]' -p eosio.token

发现是当时启动测试网时，issue发行了最大的值，一般应小余最大值10倍，及创建100亿代币的最大值，只发行10亿，之间的差额用于增发。

Returning WAST from get_code is no longer supported

2018-11-08　 Surou　阅读　 EOS-新手问答　 0 评论

问题来自 https://github.com/EOSIO/eos/issues/5640
解决方案：
To clarify: get code still works, but now retrieves wasm instead of wast. To function correctly your cleos version must match the api node’s version because of the changes.
澄清：获取代码仍然有效，但现在检索wasm而不是wast。要正常运行，由于更改，您的cleos版本必须与api节点的版本匹配。

在没有装cleos的机器无法获取，则在rpc机器添加运行参数code_as_wasm=true

还可以使用
get_raw_code_and_abi，然后把返回里的wasm字段先base64解密然后再求sha256

1.3.x没有这个get_code_hash，之后版本如果只要code_hash 的话不要用 get_code 直接用 get_code_hash 这个API。
