#C google style code

When a member throws an exception it's game over for the constructor, and that exception MUST get propagated or else your program must terminate there and then. Why would I need to remember to do this? If a member throws in an initializer list, then the constructor has failed and that exception should be propagated. are you going to remember to use the special try.catch syntax to handle exceptions thrown by constructors in initializer lists?.I'm genuinely curious as to what these are. There's all kinds of gotchas associated with exception-throwing constructors in C++. On top of this, it is hardly a minority view that throwing exceptions in constructors is problematic in many respects. I accept the third explanation, and if the style guide wishes to revise itself to say that virtual functions should not get called in a constructor, then that is reasonable. Well, you accept the third explanation, and your response to the fourth is rather unclear. Coding guidelines are always going to be an area where reasonable people can disagree, but this guy writes like everyone at Google is an idiot. I was pointing to the tone of the criticism, and the fact that it has very little actual content. I don't think it's fair to say this person is a nightmare to work with because he criticizes Google's C++ guidelines.

(E.g., are you going to remember to use the special try.catch syntax to handle exceptions thrown by constructors in initializer lists? How good are you at keeping track of whether all of the memory allocated within the constructor gets deallocated on all code paths which throw an exception?) But then, how are we in any position to assess whether or not this is true for Google? It all depends on the technical details. You may think that they're wrong about this, and that the benefits of using exceptions would outweigh the costs. They explain in their guidelines that they choose to do this primarily due to the difficulty of integrating code that uses exceptions with their (presumably very large) legacy code base. As for the first and second, your responses depend on the assumption that Google has no good reason to ban the use of exceptions in C++, which is debatable. That is fair game for criticism and there's nothing wrong with pointing that out. I think many sensible C++ developers are scratching their head wondering how a company as great as Google is using a language like C++ in such an archaic fashion.Д¬++ is not Java, and yet much of this style-guide is written as if it was Java and that C++ code should be written in a Java-like fashion. Then this is a problem with their codebase then, plain and simple, it has nothing to do with doing work in constructors. If someone creates a global variable of this type (which is against the rules, but still), the constructor code will be called before main(), possibly breaking some implicit assumptions in the constructor code.Future modification to your class can quietly introduce this problem even if your class is not currently subclassed, causing much confusion.ДЄgreed, there is something very wrong about calling virtual functions from a constructor. If the work calls virtual functions, these calls will not get dispatched to the subclass implementations.No, the object will cease to exist, because when you fail in a constructor you throw an exception as is standard when programming in C++. If the work fails, we now have an object whose initialization code failed, so it may be an indeterminate state.The fact that exceptions are forbidden at Google is just a head scratcher. There is no easy way for constructors to signal errors, short of using exceptions (which are forbidden).Д®xceptions are a perfectly easy and normal way to signal an error in a constructor.Are you interested in promoting your own content?
