Git如何永久删除历史文件
通过以下命令，就可以永久删除你想要删除的任何文件：
git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch path-to-your-remove-file' --prune-empty --tag-name-filter cat -- --all
将path-to-your-remove-file替换为删除文件的相对路径，并执行。如果有以下执行反馈，说明删除成功了
Ref 'refs/heads/master' was rewritten Ref 'refs/remotes/origin/master' was rewritten WARNING: Ref 'refs/remotes/origin/master' is unchanged Ref 'refs/tags/0.1' was rewritten Ref 'refs/tags/v0.2' was rewritten
如果所有分支都是unchanged说明要么是该分支没有要删除的文件，要么是删除文件的路径不对。
此时你会发现本地目录中的.git文件并不会马上就变小，而是与原来是一样的，
是因为Git仓库历史有个缓存期，如果不主动回收、清理仓库历史，一般的这些记录还会保存一段时间，以备你突然后悔了，没办法找回删掉的文件。
通过以下命令主动回收资源：
rm -rf .git/refs/original/ git reflog expire --expire=now --all git gc --prune=now git gc --aggressive --prune=now
执行以上命令，就会发现.git目录变小了。那么接下来只要把本地的记录，强制更新到远程仓库就行了。
git push origin --force --all git push origin --force --tags
# 查看历史大文件
git rev-list --objects --all | grep "$(git verify-pack -v .git/objects/pack/*.idx | sort -k 3 -n | tail -5 | awk '{print$1}')"

VS 2017 调试c++ dll的两种方式
环境状况：dll采用c++编写，宿主exe程序采用c#编写，两者不在同一解决方案中 方法一：手动附加 1、编译debug模式dll，放到exe所在目录 2、启动exe（非vs调试模式） 3、在dll项目中选择 调试-附加到进程，选中对应的exe进程，调试代码类型选择：本机。执行到dll调用时即可进入代码调试 注：可以在exe的main函数中加入一段sleep以等待被附加 方法二：自动附加 1、编译debug模式dll，放到exe所在目录 2、打开dll项目属性，调试-命令，输入exe的完整路径，命令参数中填入exe所需的参数（要确保选项“附加”为否） 3、在dll项目上点击右键-调试-启动新实例，即可自动启动exe并附加到此进程
用VC和MinGW导出dll的def和lib(a)文件
有了dll文件需要导出def文件： In msys2: pacman -S mingw-w64-x86_64-tools or x86: pacman -S mingw-w64-i686-tools gendef zlib1.dll In MinGW: pexports zlib1.dll > zlib1.def 有了dll和def文件，需要导出MinGW的.a文件： dlltool --dllname zlib1.dll --def zlib1.def --output-lib libz.dll.a 有了dll和def文件，需要导出一个VC的lib文件： 运行VS开发人员命令提示符 lib /machine:X64 /def:zlib1.def or x86: lib /machine:i386 /def:zlib1.def 注意： C++的dll不具有2进制级别的共享性，也就是说VC的MinGW的C++ dll不能混用。 而C的可以。 pexports和dlltool的MinGW的工具，lib是VC的工具。
