Some exception hierarchies can not be modified to make boost::(:link </string>
+ <string>(:auto !!!:)

Traditionally, when using exceptions to report failures, the throw site:

*creates an exception object of the appropriate type, and
*stuffs it with data relevant to the detected error.

A higher context in the program contains a catch statement which:

*selects failures based on exception types, and
*inspects exception objects for data required to deal with the problem.

The main issue with this "traditional" approach is that often, the data available at the point of the throw is insufficient for the catch site to handle the failure.

Here is an example of a catch statement:

[@catch( file_read_error & e )
 {
 std::cerr << e.file_name();
 }@]

And here is a possible matching throw:

[@void
read_file( FILE * f )
 {
 ....
 size_t nr=fread(buf,1,count,f);
 if( ferror(f) )
 throw file_read_error(???);
 ....&#
10; }@]

Clearly, the problem is that the handler requires a file name but the read_file function does not have a file name to put in the exception object; all it has is a FILE pointer!

In an attempt to deal with this problem, we could modify read_file to accept a file name:

[@void
read_file( FILE * f, char const * name )
 {
 ....
 size_t nr=fread(buf,1,count,f);
 if( ferror(f) )
 throw file_read_error(name);
 ....
 }@]

This is not a real solution: it simply shifts the burden of supplying a file name to the immediate caller of the read_file function.

->''In general, the data required to handle a given library-emitted exception depends on the program that links to it. Many contexts between the throw and the catch may have relevant information which must be transported to the exception handler.''

!!!Exception wrapping

The idea of exception wrapping is to catch an exce
ption from a lower level function (such as the read_file function above), and throw a new exception object that contains the original exception (and also carries a file name.) This method seems to be particularly popular with C++ programmers with Java background.

Exception wrapping leads to the following problems:

*To wrap an exception object it must be copied, which may result in slicing.
*Wrapping is practically impossible to use in generic contexts.

The second point is actually special case of violating the exception neutrality principle. Most contexts in a program can not handle exceptions; such contexts should not interfere with the process of exception handling.

!!!The boost::exception solution

*Simply derive your exception types from boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-11</id>
+ <id>-78</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) a base type. In this case, the (:link </string>
+ <string>:).
*Confidently limit the throw site to provide only data that is available naturally.
*Use exception-neutral contexts between the throw and the catch to augment exceptions with more relevant data as they bubble up.

For example, in the throw statement below we only add the errno code, since this is the only failure-relevant information available in this context:

[@struct exception_base: virtual std::exception, virtual boost::(:link </string>

`#include <(:link </string>
+ <string>:), what data a given exception object transports depends primarily on the context in which failures are reported (not on its type.) Since exception types need no members, it becomes very natural to throw exceptions that derive from more than one type to indicate multiple appropriate semantics:

[@struct exception_base: virtual std::exception, virtual boost::(:link </string>

struct file_error: virtual io_error { };

Using this approach, exception types become a simple tagging system for categorizing errors and selecting failures in exception handlers.

- <string>!!Introduction

The purpose of Boost Exception is to ease the design of exception class hierarchies and to help write exception handling and error reporting code.

It supports transporting of arbitrary data to the catch site, which is otherwise tricky due to the no-throw requirements (15.5.1) for exception types. Data can be added to any exception object, either directly in the throw-expression (15.1), or at a later time as the exception object propagates up the call stack.

The ability to add data to exception objects after they have been passed to throw is important, because often some of the information needed to handle an exception is unavailable in the context where the failure is detected. 

Boost Exception also supports (:link http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html|N2179:)-style (:link </string>
+ <string>:) objects in it. The syntactic sugar provided by (:link </string>

which saves typing compared to this possible alternative:

e.add(foo_info(foo));
e.add(bar_info(bar));
throw e;@]

and looks better than something like:

[@throw error().add(foo_info(foo)).add(bar_info(bar));@]

!!!Why is operator<< allowed to throw?

This question is referring to the following issue. Consider this throw statement example:

[@throw file_open_error() (:link </string>

- <string> mod="w":)
##(:link </string>
+ <string>|<<:) file_name(fn);@]

The intention here is to throw a file_open_error, however if (:link </string>
 <variant>1</variant>

##(:link </string>

Bjarne Stroustrup, The C++ Programming Language, 3rd Edition, page 371:

->''"Throwing an exception requires an object to throw. A C++ implementation is required to have enough spare memory to be able to throw bad_alloc in case of memory exhaustion. However, it is possible that throwing some other exception will cause memory exhaustion."''

So, an attempt to throw any exception may already result in propagating std::bad_alloc instead.

Traditionally, when using exceptions to report failures, the throw site:

*creates an exception object of the appropriate type, and
*stuffs it with data relevant to the detected error.

A higher context in the program contains a catch statement which:

*selects failures based on exception types, and
*inspects exception objects for data required to deal with the problem.

The main issue with this "traditional" approach is that often, the data available at the point of the throw is insufficient for the catch site to handle the failure.

Here is an example of a catch statement:

[@catch( file_read_error & e )
 {
 std::cerr << e.file_name();
 }@]

And here is a possible matching throw:

[@void
read_file( FILE * f )
 {
 ....
 size_t nr=fread(buf,1,count,f);
 if( ferror(f) )
 throw file_read_error(???);
 ....&#
10; }@]

Clearly, the problem is that the handler requires a file name but the read_file function does not have a file name to put in the exception object; all it has is a FILE pointer!

In an attempt to deal with this problem, we could modify read_file to accept a file name:

[@void
read_file( FILE * f, char const * name )
 {
 ....
 size_t nr=fread(buf,1,count,f);
 if( ferror(f) )
 throw file_read_error(name);
 ....
 }@]

This is not a real solution: it simply shifts the burden of supplying a file name to the immediate caller of the read_file function.

->''In general, the data required to handle a given library-emitted exception depends on the program that links to it. Many contexts between the throw and the catch may have relevant information which must be transported to the exception handler.''

!!!Exception wrapping

The idea of exception wrapping is to catch an exce
ption from a lower level function (such as the read_file function above), and throw a new exception object that contains the original exception (and also carries a file name.) This method seems to be particularly popular with C++ programmers with Java background.

Exception wrapping leads to the following problems:

*To wrap an exception object it must be copied, which may result in slicing.
*Wrapping is practically impossible to use in generic contexts.

The second point is actually special case of violating the exception neutrality principle. Most contexts in a program can not handle exceptions; such contexts should not interfere with the process of exception handling.

!!!The boost::exception solution

*Simply derive your exception types from boost::(:link </string>
+ <string>:) overload of (:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-11</id>
+ <id>-30</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:).
*Confidently limit the throw site to provide only data that is available naturally.
*Use exception-neutral contexts between the throw and the catch to augment exceptions with more relevant data as they bubble up.

For example, in the throw statement below we only add the errno code, since this is the only failure-relevant information available in this context:

[@struct exception_base: virtual std::exception, virtual boost::(:link </string>
+ <string>:) is equivalent to:

[@if( p )
 try
 {
 (:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-11</id>
+ <id>-69</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) { };
struct io_error: virtual exception_base { };
struct file_read_error: virtual io_error { };

typedef boost::(:link </string>
+ <string>:)(p);
 }

 {
 return (:link </string>

 if( ferror(f) )
 throw file_read_error() (:link </string>
+ <string>:)();
 }
else return <unspecified-string-value>;@]

*The returned string is ''not'' user-friendly.
*The returned string may include additional platform-specific diagnostic information.

Boost Exception responds to the following configuration macros:

'''BOOST_NO_RTTI'''\\
'''BOOST_NO_TYPEID'''

The first macro prevents Boost Exception from using dynamic_cast and dynamic typeid. If the second macro is also defined, Boost Exception does not use static typeid either. There are no observable degrading effects on the library functionality, except for the following:

Boost Exception responds to the following configuration macros:

'''BOOST_NO_RTTI'''\\
'''BOOST_NO_TYPEID'''

The first macro prevents Boost Exception from using dynamic_cast and dynamic typeid. If the second macro is also defined, Boost Exception does not use static typeid either. There are no observable degrading effects on the library functionality, except for the following:

->By default, the (:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-52</id>
+ <id>-14</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) are equivalent and compare equal if and only if they refer to the same exception.

The default constructor of (:link </string>
+ <string>:) function template can be called with any exception type. If BOOST_NO_RTTI is defined, (:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-52</id>
+ <id>-14</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) produces the null value of the type. The null value is equivalent only to itself.

!!!!Thread safety

* It is legal for multiple threads to hold (:link </string>
+ <string>:) can be used only with objects of type boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) references to the same exception object.
* It is illegal for multiple threads to modify the same (:link </string>
+ <string>:).

!!!!Note:

The library needs RTTI functionality. Disabling the language RTTI support enables an internal RTTI system, which may have more or less overhead depending on the platform.

'''BOOST_EXCEPTION_DISABLE'''

By default, (:link </string>
 <variant>1</variant>

 <shared_ptr>
- <id>-52</id>
+ <id>-45</id>
 </shared_ptr>

 </weak_ptr>

- <string>:) makes a copy of the current exception object, it is still possible for the two copies to share internal state. Therefore, in general it is not safe to call (:link </string>

 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) concurrently to throw the same exception object into multiple threads.

!!!!Nesting of exceptions:

An (:link </string>
+ <string>:) function. Defining BOOST_EXCEPTION_DISABLE disables this integration.

Note that on some non-conformant compilers, for example MSVC 7.0 and older, as well as BCC, BOOST_EXCEPTION_DISABLE is implicitly defined in (:link </string>
 <variant>1</variant>
 <weak_ptr>

- <string>:) instance for transporting the name of a relevant API function (which does not use exceptions to report errors) in exceptions deriving from boost::(:link </string>
+ <string>(:auto !!!:)

Exception types should use virtual inheritance when deriving from other exception types. This insight is due to Andrew Koenig. Using virtual inheritance prevents ambiguity problems in the exception handler:

[@#include <iostream>
struct my_exc1 : std::exception { char const* what() const throw(); };
struct my_exc2 : std::exception { char const* what() const throw(); };
struct your_exc3 : my_exc1, my_exc2 {};

int
main()
 {
 try { throw your_exc3(); }
 catch(std::exception const& e) {}
 catch(...) { std::cout << "whoops!" << std::endl; }
 }@]

The program above outputs "whoops!" because the conversion to std::exception is ambiguous.

The overhead introduced by virtual inheritance is always negligible in the context of exception handling. Note that virtual bases are initialized directly by the constructor of the most-derived-type (the type pass
ed to the throw statement, in case of exceptions.) However, typically this detail is of no concern when boost::(:link </string>

The purpose of Boost Exception is to ease the design of exception class hierarchies and to help write exception handling and error reporting code.

It supports transporting of arbitrary data to the catch site, which is otherwise tricky due to the no-throw requirements (15.5.1) for exception types. Data can be added to any exception object, either directly in the throw-expression (15.1), or at a later time as the exception object propagates up the call stack.

The ability to add data to exception objects after they have been passed to throw is important, because often some of the information needed to handle an exception is unavailable in the context where the failure is detected. 

Boost Exception also supports (:link http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html|N2179:)-style (:link </string>

- <string>:), virtual std::exception { }; //(2)

void
f()
 {
 throw my_error() << my_info(42); //(3)
 }@]

First, we instantiate the (:link </string>
+ <string>:) function.

- <string>:) template using a unique identifier -- tag_my_info, and the type of the info it identifies -- int. This provides compile-time type safety for the various values stored in exception objects.

Second, we define class my_error, which derives from boost::(:link </string>

- <string>|operator<<:) to store values in exception objects at the point of the throw.

The stored my_info value can be recovered at a later time like this:

- <string>:) should not be used to replace std::exception as a base type in exception type hierarchies. Instead, it should be included as a virtual base, in addition to std::exception (which should also be derived virtually.)

!!!Why is boost::exception abstract?

To prevent exception-neutral contexts from erroneously erasing the type of the original exception when adding (:link </string>

!!!What is the space overhead of the boost::exception base class?

- <string>:). Such concerns are dictated by the typical strict interpretation of a common principle in C and C++, that users only pay for features they actually use.

The problem is that users of Boost Exception can't by themselves cause a library to throw types that derive from boost::(:link </string>

#include <(:link </string>

 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:), and without this they can't use any of the Boost Exception facilities.

For example, if a user wants to use Boost Serialization in a separate thread, it is desirable to be able to transport exceptions emitted by that library into the main thread where they can be analyzed to generate a user-friendly message. This can be easily achieved using boost::(:link </string>
+ <string>:)>
#include <(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-52</id>
+ <id>-8</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:), but this requires that Boost Serialization throws exceptions using boost::(:link </string>
+ <string>:)>
#include <(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>
- <id>-28</id>

- <string>:). If Boost Serialization calls boost::(:link </string>
+ <string>:)>
#include <(:link </string>
 <variant>1</variant>
 <weak_ptr>

 <shared_ptr>
- <id>-26</id>
+ <id>-5</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) to throw, this behavior happens automatically and transparently.

The cost of this integration is:

* In terms of space: a pointer and 3 ints are added to the static size of exception objects.
* In terms of speed: the pointer is initialized to null at the point of the throw.
* In terms of coupling: about 400 self-contained lines of C++ with no external includes.

!!!Why use operator<< overload for adding info to exceptions?

#include <(:link </string>

- <string>:) allows this to be done directly in a throw expression:

[@throw error() (:link </string>

struct file_error : virtual error { };
struct file_open_error: virtual file_error { };
struct file_read_error: virtual file_error { };

boost::shared_ptr<FILE>
open_file( char const * file, char const * mode )
 {
 if( FILE * f=fopen(file,mode) )
 return boost::shared_ptr<FILE>(f,fclose);
 else

- <string>|<<:) bar_info(bar);@]

which saves typing compared to this possible alternative:

[@error e;
e.add(foo_info(foo));
e.add(bar_info(bar));
throw e;@]

and looks better than something like:

[@throw error().add(foo_info(foo)).add(bar_info(bar));@]

!!!Why is operator<< allowed to throw?

This question is referring to the following issue. Consider this throw statement example:

[@throw file_open_error() (:link </string>
+ <string>:)("fopen") <<
 boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>

 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>|<<:) file_name(fn);@]

The intention here is to throw a file_open_error, however if (:link </string>
+ <string>:)(errno) <<
 boost::(:link </string>
 <variant>1</variant>
 <weak_ptr>
 <expired>0</expired>
 <shared_ptr>

 </weak_ptr>
 <variant>2</variant>
- <string> mod="/":) fails to copy the std::string contained in the file_name (:link </string>

 <shared_ptr>
- <id>-57</id>
+ <id>-7</id>
 </shared_ptr>
 </weak_ptr>
 <variant>2</variant>
- <string>:) wrapper, a std::bad_alloc could propagate instead. This behavior seems undesirable to some programmers.

Bjarne Stroustrup, The C++ Programming Language, 3rd Edition, page 371:

->''"Throwing an exception requires an object to throw. A C++ implementation is required to have enough spare memory to be able to throw bad_alloc in case of memory exhaustion. However, it is possible that throwing some other exception will cause memory exhaustion."''

So, an attempt to throw any exception may already result in propagating std::bad_alloc instead.

Exception types should use virtual inheritance when deriving from other exception types. This insight is due to Andrew Koenig. Using virtual inheritance prevents ambiguity problems in the exception handler:

[@#include <iostream>
struct my_exc1 : std::exception { char const* what() const throw(); };
struct my_exc2 : std::exception { char const* what() const throw(); };
struct your_exc3 : my_exc1, my_exc2 {};

int
main()
 {
 try { throw your_exc3(); }
 catch(std::exception const& e) {}
 catch(...) { std::cout << "whoops!" << std::endl; }
 }@]

The program above outputs "whoops!" because the conversion to std::exception is ambiguous.

The overhead introduced by virtual inheritance is always negligible in the context of exception handling. Note that virtual bases are initialized directly by the constructor of the most-derived-type (the type pass
ed to the throw statement, in case of exceptions.) However, typically this detail is of no concern when boost::(:link </string>
