关于windows环境下CRLF line deliminator 的说明

1. git 有一个config 叫core.autocrlf 如果设置为true的话， windows下git会在

• checkout的时候把LF转换为CRLF (如果这时用eslint的linebreak-style进行较难的话会报错 message: 'Expected linebreaks to be 'LF' but found 'CRLF'. (linebreak-style)' )
• push 的时候把CRLF转换为LF (这样保证服务器上还是LF）
• 解决办法如2，3描述

2. .gitattributes这个文件里面可以控制git在clone代码时对于line deliminator的转换 添加如下规则：

*.js text eol=lf

reference I met a exception when execution as instructions on soot homepage

soot Exception in thread "main" java.lang.RuntimeException: Could not load classfile: java.lang.CharSequence

This is caused by a high version of JDK(1.8.0)

switching to a lower version of jdk (1.6 or 1.7) solves this problem

cheers!~

Aliyun Reference 按照他提供的方法：

1. 去掉DEFINER=root@`% 类似的子句

sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/ ' your.sql > your_revised.sql

2. 检查 SQL 文件，去除下面类似的语句

Reference when executing df -hl shows /tmp is mounted on overflow :

overflow          1.0M  1.0M     0 100% /tmp

If your “/tmp” mount on a linux filesystem is mounted as overflow (often sized at 1MB), this is likely due to you not specifying “/tmp” as its own partition and your root filesystem filled up and “/tmp” was remounted as a fallback. To fix this after you’ve cleared space, just unmount the fallback and it should remount at its original point:

sudo umount overflow
