我应该将带有调试信息的发布版本编译为“完整"吗?还是“仅限 pdb"? [英] Should I compile release builds with debug info as "full" or "pdb-only"?

问题描述

在 C# 项目的 Visual Studio 中，如果您转到项目属性 >构建 >高级 >Debug Info 您有三个选项:none、full 或 pdb-only.

In Visual Studio for a C# project, if you go to Project Properties > Build > Advanced > Debug Info you have three options: none, full, or pdb-only.

哪种设置最适合发布版本?

Which setting is the most appropriate for a release build?

那么，full 和 pdb-only 有什么区别?

So, what are the differences between full and pdb-only?

如果我使用 full 会对性能产生影响吗?如果我使用 pdb-only 会更难调试生产问题吗?

If I use full will there be performance ramifications? If I use pdb-only will it be harder to debug production issues?

推荐答案

我会使用 pdb-only 构建.您将无法将调试器附加到已发布的产品，但如果您收到故障转储，您可以使用 Visual Studio 或 WinDBG 检查崩溃时的堆栈跟踪和内存转储.

I would build with pdb-only. You will not be able to attach a debugger to the released product, but if you get a crash dump, you can use Visual Studio or WinDBG to examine the stack traces and memory dumps at the time of the crash.

如果您使用 full 而不是 pdb-only，您将获得相同的好处，除了可执行文件可以直接附加到调试器.鉴于您的产品，您需要确定这是否合理.客户.

If you go with full rather than pdb-only, you'll get the same benefits, except that the executable can be attached directly to a debugger. You'll need to determine if this is reasonable given your product & customers.

请务必将 PDB 文件保存在某处，以便在出现崩溃报告时可以参考它们.如果您可以设置 符号服务器来存储那些调试符号，这样就更好了.

Be sure to save the PDB files somewhere so that you can reference them when a crash report comes in. If you can set up a symbol server to store those debugging symbols, so much the better.

如果您选择使用 none 进行构建，则在现场发生崩溃时您将无法追索.您将无法对事故进行任何事后检查，这可能会严重影响您追查问题的能力.

If you opt to build with none, you will have no recourse when there's a crash in the field. You won't be able to do any sort of after-the-fact examination of the crash, which could severely hamper your ability to track down the problem.

关于性能的说明:

John Robbins 和 Eric Lippert 已经写了博客关于 /debug 标志的帖子，它们都表明此设置对性能的零影响.有一个单独的 /optimize 标志指示编译器是否应该执行优化.

Both John Robbins and Eric Lippert have written blog posts about the /debug flag, and they both indicate that this setting has zero performance impact. There is a separate /optimize flag which dictates whether the compiler should perform optimizations.
