Clang Cannot Use 'throw' With Exceptions Disabled
Two general topics of discussion follow: exception neutrality and exception fexceptions android safety. Exception Safety What is exception-safe code? Will define this as reasonable and well-defined behavior by clang enable exceptions classes and functions from the standard library when used by user-defined classes and functions that are themselves exception safe. Please note that using exceptions in

combination with templates imposes an additional requirement for exception safety. Instantiating types are required to have destructors that do no throw. Using the layered approach from Abrahams, can classify library components as providing set levels of safety. These will be called exception guarantees, and can be divided into three categories. One.

throw. As specified in 23.2.1 general container requirements. Applicable to container and string classes. Member functions erase, pop_back, pop_front, swap, clear. And iterator copy constructor and assignment operator. Two. Don't leak resources when exceptions are thrown. This is also referred to as the “basic” exception safety guarantee. This applicable throughout the standard library. Three. Commit-or-rollback semantics. This is referred to as “strong” exception safety guarantee. As specified in 23.2.1 general container requirements. Applicable to container and string classes. Member functions insert of a single element, push_back, push_front, and rehash. Exception Neutrality Simply put, once thrown an exception object should continue in flight unless handled explicitly. In practice, this means propagating exceptions should not be swallowed in gratuitous catch(...) blocks. Instead, matching try and catch blocks should have specific catch handlers and allow un-handed exception objects to propagate. If a terminating catch(...) blocks exist then it should end with a throw to re-thr

In this post I will walk you through the features of this new window. For more information on exception classifications in Visual Studio, see Understanding Exceptions while Debugging with Visual Studio. Now in a Tool Window In previous versions of Visual Studio, when you wanted to configure exception settings you would have to go to the modal, slow-opening, hard-to-search Exceptions Dialog. We heard all of your feedback, so we built an improved Exception Settings window. We have taken all of the useful functionality of that old dialog and put it into this convenient and easy to use tool window. To access this window go to the Debug men
Nethercote| 17 Comments When Firefox is built with GCC, the -fno-exceptions option is used, which means that exception-handling is disabled. I've been told https://blog.mozilla.org/nnethercote/2011/01/18/the-dangers-of-fno-exceptions/ that this is because the performance of code that uses exceptions is unacceptable. Sounds simple, until you realize that libraries such as libstdc++.so are not built with this option. https://docs.oracle.com/cd/B13789_01/appdev.101/b10807/07_errs.htm This means, for example, that the vanilla operator new will throw an exception if it fails, because it's in libstdc++.so, but Firefox code cannot catch the exception, because -fno-exceptions cannot use is specified. (If you write a try-block, GCC will give you an error.) This has important consequences: if you compile your application with -fno-exceptions, you cannot use any standard library functions that might throw exceptions. SpiderMonkey's C++ coding standard is succinct, perhaps overly so: "No exceptions, so std is hard to use." Another fine example of the "so you with exceptions disabled think you'll be able to use a subset of C++, eh?" fallacy. See bug 624878 for a specific manifestation of this problem. I wonder if there are others case like that in Firefox. This entry was posted in Cplusplus, Firefox.

Sure would be nice if we fixed the performance problems (which are fixable -- at least for GCC the only actual issue is a bunch of extra runtime relocations, that could be gotten rid of, AFAIK) before we were up against the wall. Luke Wagner | January 18, 2011 at 4:57 pm | Fallacy? Isn't SM (after bug 624878 of course 🙂 a demonstration of us doing just that?

shot at without result. —Winston Churchill Run-time errors arise from design faults, coding mistakes, hardware failures, and many other sources. Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program. With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. With PL/SQL, a mechanism called exception handling lets you "bulletproof" your program so that it can continue operating in the presence of errors. This chapter contains these topics: Overview of PL/SQL Runtime Error Handling Advantages of PL/SQL Exceptions Summary of Predefined PL/SQL Exceptions Defining Your Own PL/SQL Exceptions How PL/SQL Exceptions Are Raised How PL/SQL Exceptions Propagate Reraising a PL/SQL Exception Handling Raised PL/SQL Exceptions Tips for Handling PL/SQL Errors Overview of PL/SQL Compile-Time Warnings Overview of PL/SQL Runtime Error Handling In PL/SQL, an error condition is called an exception. Exceptions can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions include division by zero and out of memory. Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define exceptions of your own in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. Unlike internal exceptions, user-defined exceptions must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements, which can also raise predefined exceptions. To handle raised exceptions, you write separate routi
