您好 前辈 执行./coverage_build.sh 时有如下错误

Note: You need to delete the existing /tmp/coverage.index first for this testing!

我执行了删除/tmp/coverage.index的命令 还是不可以 一样的错误
执行./demo_build.sh都是没问题的

[begeekmyfriend]

你的机器是什么配置？32-bit等

[LiDing0611]

是64的

[begeekmyfriend]

没法复现，打印一下len和_block_size分别多少

[LiDing0611]

好的 我试下 或者换个环境吧 多谢多谢

[begeekmyfriend]

我在Ubuntu 16.04上很好地执行，你是否改了源代码？

[LiDing0611]

我的机器是SUSE Linux 看你这个代码比较精简 有在这个基础上加Anti-Caching的想法

[begeekmyfriend]

Then there are bugs in your modification absolutely.

[LiDing0611]

我还没开始加东西啊 就是执行你的这个代码 找了一下午没找出原因 会不会SUSE环境的影响吧 我刚试了下redhat 是ok的

[begeekmyfriend]

打印一下len和_block_size吧，这里可是用的系统调用pread，搞不定SUSE系统有bug呢

[LiDing0611]

嗯嗯 我找到原因了 我这个/tmp下还有一个coverage.index.boot文件 需要把这个也删掉才可以运行 还有一个小问题 你那个测试性能读写时间的结果是保存在了哪个文件里

[begeekmyfriend]

我不记得有测试性能读写时间的benchmark

[LiDing0611]

https://www.jianshu.com/p/a8d3432f3840 我看这个里有 没有的话我自己加一个

[begeekmyfriend]

没想到我的项目都有人改写并写成博客了，行，你自己加吧

[LiDing0611]

哈哈 点个赞 因为写的很棒

[begeekmyfriend]

我怀疑他这是内存版本，不然怎么会快400倍……

[begeekmyfriend]

哦，看错了，他之前是链表版本

[LiDing0611]

我还一直以为这个blog也是你更新的

[begeekmyfriend]

我会为了一个repo去写blog，还系列？
