What are your best practices for C++ exception handling?

I searched the Internet and found a lot of articles about this topic. However, I found there is no complete checklist to verify our code's quality of exception-safety.

So, I want to collect valuable best practices for C++ exception handling from you.

I first list some practices of my own:

1. Catch all exceptions if any in destructors:

   struct A
   {
       ~A()
       {
           try
           {
               // Here may throw exceptions
           }
           catch (std::runtime_error& e)
           {}
           catch (...)
           {
               logging("...");
           }
       }
   };
   

2. Add function name, source file name and line numer in exception information. __func__, __FILE__ and __LINE__ are good friends.

3. Never use exception specifications. The reason is given in the book "C++ Coding Standards".

What are yours?
