-[section Advanced] - -This section is a guide to advanced usages of this library. - -[section Pure Virtual Public Functions] - -In C++, pure virtual functions are allowed to have a /default implementation/ as long as such implementation is programmed out-of-line so defined outside the class declaring the pure virtual function `virtual ... = 0;`. - -Contracts for pure virtual public functions are programmed using the [funcref boost::contract::public_function] function like for (non-pure) virtual public functions (all consideration made in __Virtual_Public_Functions__ apply). -However, contracts have to be programmed out-of-line, in the default implementation of the pure virtual function. -For example (see [@../../example/features/pure_virtual_public.cpp =pure_virtual_public.cpp=]): - -[import ../example/features/pure_virtual_public.cpp] -[pure_virtual_public_base_begin] -[pure_virtual_public_base_end] -[pure_virtual_public_base_impl] - -This library will never actually execute the pure virtual function body while it is calling the pure virtual function default implementation to check contracts for subcontracting. -Therefore, programmers can safely `assert(false)` at the beginning of the body if they intend for that body to never be executed (or they can program a working body in case they need to use C++ pure virtual function default implementation as usual with C++). - -[heading Subcontracting Preconditions Always True/False] - -As seen in __Public_Function_Overrides__, preconditions of overriding public functions are checked in __OR__ with preconditions of overridden virtual public functions. -Therefore, if a virtual public function in a base class specifies no precondition then preconditions specified by all its overriding functions in derived classes will have no effect (because when checked in __OR__ with the overridden function from the base class that has no preconditions, they will always pass). -This correctly reflects the fact that the overridden function in the base class can be called from any context (because it has no precondition) and so must all its overriding functions in all derived classes in accordance to the __substitution_principle__. -This is equivalent to declare the virtual public function in a base class with a single precondition `BOOST_CONTRACT_ASSERT(true)` that will always pass: - - // In a virtual public function of a base class. - boost::contract::check c = boost::contract::public_function(v, this) - .precondition([&] { - BOOST_CONTRACT_ASSERT(true); // Prevent preconditions of overrides. - }) - ... - ; - -On the flip side, programmers might sometimes consider to declare a pure virtual public function in a base class with a single precondition `BOOST_CONTRACT_ASSERT(false)` that will always fail. -This indicates that the pure virtual public function can never be called unless it is redefined by a derived class (which is actually the case with C++ pure virtual functions) and also that the base class designers have intentionally left it up to derived classes to specify preconditions for the pure virtual function in question. -This technique might make sense only for preconditions of pure virtual public functions (otherwise `BOOST_CONTRACT_ASSERT(false)` will prevent calling virtual public functions in concrete bases). -For example (see [@../../example/features/named_override.cpp =named_override.cpp=]): - -[import ../example/features/named_override.cpp] -[named_override_pure_virtual_assert_false] - -That said, the need to declare such a precondition `BOOST_CONTRACT_ASSERT(false)` that will always fail might be an indication that the base class interface is not correctly designed. -In general, the base class interface should still contain all functions (eventually as pure virtual) that are necessary to program its contracts. - -[endsect] - -[section Optional Return Value] - -It is possible to use `boost::optional` to handle return values when programmers cannot construct the result variable at its point of declaration before the contract (e.g., because an appropriate constructor for the return type is not available at that point, or just because it would be too expensive to execute an extra initialization of the return value at run-time). -[footnote -*Rationale:* -`boost::optional` is used instead of `std::optional` because `std::optional` is not part of C++ standards prior to C++17. -] -For example (see [@../../example/features/optional_result.cpp =optional_result.cpp=]): - -[import ../example/features/optional_result.cpp] -[optional_result] - -In this example the return type is a reference so it does not have default constructor that can be used to initialize `result` when it is declared before the contract declaration. -In addition, `Index` needs to be validated to be smaller than `size()` by the precondition before it can be used to retrieve the reference to be assigned to `result` so `vect[Index]` cannot be used to initialize `result` when it is declared before the contract declaration. -Therefore, `boost::optional` is used to defer `result` proper initialization until the execution of the function body after the contract declaration when `Index` has been validated by the precondition and `vect[Index]` can be safely evaluated to initialize `result`. - -As seen in __Return_Value__, it is the responsibility of the programmers to ensure that `result` is always set to the return value (when the function exits without trowing an exception). -This also ensures that `result` is always set before the postconditions are checked so programmers can always dereference `result` in postconditions to access the return value (using `operator*` and `operator->` as usual with `boost::optional`, and without having to explicitly check if `result` is an empty `boost::optional` object or not). -This can be easily done by making sure that /all/ return statements in the function are of the form: - - boost::optional<...> result; - ... - return *(result = ...); // Assign `result` at each return. - -[heading Optional Results in Virtual Public Functions] - -Similarly, `boost::optional` can be used to handle the return value passed to contracts of virtual public functions (pure or not) and of public function overrides. -As seen in __Pure_Virtual_Public_Functions__, __Virtual_Public_Functions__, and __Public_Function_Overrides__, in these cases the return value `result` must be passed as a parameter to [funcref boost::contract::public_function] right after the parameter `v` of type [classref boost::contract::virtual_]`*`. -Then the functor passed to `.postcondition(...)` takes one single parameter of type `boost::optional<`[^['result-type]]` const&> const&`. -For example (see [@../../example/features/optional_result_virtual.cpp =optional_result_virtual.cpp=]): - -[import ../example/features/optional_result_virtual.cpp] -[optional_result_virtual] - -The inner `const&` in the postcondition functor parameter type `boost::optional<... const&> ...` is mandatory (while the outer `const&` in the postcondition functor parameter type `boost::optional<...> const&` is not). -[footnote -*Rationale:* -This library requires the postcondition functor parameter to be of type `boost::optional<... const&>` so the return value does not have to be copied (because of `&`) while postconditions are still not allowed to change its value (because of `const`, see __Constant_Correctness__). -In addition, programmers are encouraged to declare the postcondition functor to take its argument also as a constant reference `boost::optional<... const&> const&` to avoid possibly expensive copies of the `boost::optional` type. -] - -[endsect] - -[section Private and Protected Functions] - -Private and protected functions do not check class invariants (because they are not part of the public class interface) and they do not subcontract (because they are not accessible at the calling site where the __substitution_principle__ applies, see __Function_Calls__). -However, programmers may still want to specify preconditions and postconditions for private and protected functions when they want to check correctness of their implementation and usage from within the class, base classes, and friend classes or functions. -When programmers decide to specify contracts for private and protected functions, they shall use [funcref boost::contract::function] (like for non-member functions). -For example (see [@../../example/features/private_protected.cpp =private_protected.cpp=]): - -[import ../example/features/private_protected.cpp] -[private_protected] - -Considerations made in __Non_Member_Functions__ apply to private and protected functions as well. - -See __Constructors__ and __Destructors__ on how to program contracts for private and protected constructors and destructors instead. - -[heading Virtual Private and Protected Functions] - -When private and protected functions are virtual they should still declare the extra virtual parameter of type [classref boost::contract::virtual_]`*` with default value `0` (see __Virtual_Public_Functions__) even if that parameter does not have to be passed to [macroref BOOST_CONTRACT_OLDOF] and [funcref boost::contract::function] takes no argument (so the extra virtual parameter will remain unused and it does not need a name). -[footnote -Technically, the extra virtual parameter can still be passed to [macroref BOOST_CONTRACT_OLDOF] but that is not necessary and it has no effect so it is not done in this documentation. -] -That is necessary otherwise the private and protected virtual functions cannot be overridden by public functions in derived classes that specify contracts (because the [classref boost::contract::virtual_]`* = 0` parameter has to be part of signatures for public function overrides). -For example (see [@../../example/features/private_protected_virtual.cpp =private_protected_virtual.cpp=]): -

-[import ../example/features/overload.cpp] -[overload] - -Overloaded functions have the same function name so the same [^override_['function-name]] type can be reused as template parameter for all [funcref boost::contract::public_function] calls. -Therefore, [macroref BOOST_CONTRACT_OVERRIDE] only needs to be invoked once for any given function name even when that function name is overloaded. - -[endsect] - -[section Lambdas, Loops, Code Blocks (and `constexpr`)] - -While contracts are usually most useful to program specifications of functions and class interfaces, this library also allows to check contract conditions for implementation code (lambda functions, loops, code blocks, etc.). - -Lambda functions are not member functions, they are not part of class public interfaces so they do not check class invariants or participate int subcontracting. -They can use [funcref boost::contract::function] to specify preconditions, postconditions, and exception guarantees (considerations made in __Non_Member_Functions__ apply). -For example (see [@../../example/features/lambda.cpp =lambda.cpp=]): -

-[import ../example/features/code_block.cpp] -[code_block] - -Finally, at the moment this library does not support contracts for functions and classes declared `constexpr`. -[footnote -*Rationale:* -In general, it might be useful to specify contracts for `constexpr` functions and literal classes. -However, the implementation of this library cannot support contracts for these functions and classes because C++ does not currently allow `constexpr` functions to do the following: -Declare local variables of (literal) types with non-trivial `constexpr` destructors (this RAII technique is used by this library to check invariants, postconditions, and exceptions guarantees at exit); -Call other `constexpr` functions using try-catch statements (used by this library to report contract assertion failures and catch any other exception that might be thrown when evaluating the asserted conditions); -Use lambda functions (used by this library for convenience to program functors that that check preconditions, postconditions, and exception guarantees). -Also note that even if supported, contracts for `constexpr` functions probably would not use old values (because `constexpr` prevents functions from having any side effect visible to the caller and variables recording such side-effects are usually the candidates for old value copies) and subcontracting (because `constexpr` functions cannot be virtual). -] - -[endsect] - -[section Implementation Checks] - -This library provides a mechanism to check assertions within implementation code outside of preconditions, postconditions, exceptions guarantees, and class invariants. -These implementation checks can be programmed using [macroref BOOST_CONTRACT_ASSERT] in a nullary functor that is directly assigned to [classref boost::contract::check] at the place within the code where the checks have to be executed (so without using [funcref boost::contract::function], [funcref boost::contract::public_function], etc.). -For example (see [@ ../../example/features/check.cpp =check.cpp=]): - -[import ../example/features/check.cpp] -[check_class] - -Alternatively, this library provides the [macroref BOOST_CONTRACT_CHECK] macro that allows to completely remove run- and compile-time overhead of implementation checks when [macroref BOOST_CONTRACT_NO_CHECKS] is defined. -For example (see [@ ../../example/features/check.cpp =check.cpp=]): - -[check_macro] - -(See __Disable_Contract_Checking__ and __Disable_Contract_Compilation__ for macros to completely remove run- and compile-time overhead of preconditions, postconditions, exception guarantees, and class invariants.) - -These implementation checks are essentially equivalent to using the C-style `assert` macro a part from the following: - -* A failure of the implementation checks will call [funcref boost::contract::check_failure] (see [funcref boost::contract::set_check_failure] and [funcref boost::contract::get_check_failure]). -* Implementation checks are automatically disabled when other contract conditions specified using this libraries are already being checked (to avoid infinite recursion, see [macroref BOOST_CONTRACT_ALL_DISABLE_NO_ASSERTION]). -* Implementation checks are disabled defining [macroref BOOST_CONTRACT_NO_CHECKS] (instead of `NDEBUG` for disabling `assert`). - -[endsect] - -[section Old Copies at Body] - -In the examples seen so far, old value variables of type [classref boost::contract::old_ptr] are initialized to a copy of the expression passed to [macroref BOOST_CONTRACT_OLDOF] at the point of their declaration. -This is correctly done before the function body is executed but it is also done before the contract is declared, therefore even before class invariants (for public functions) and preconditions are checked at function entry. - -This might work well in most cases, however in general old values should be copied before executing the function body but after checking entry class invariants and preconditions (see __Assertions__). -Specifically, there could be cases in which it makes sense to evaluate the expressions passed to [macroref BOOST_CONTRACT_OLDOF] only assuming that the assertions programmed in the class invariants and preconditions are first checked to be true. - -This library allows to construct [classref boost::contract::old_ptr] variables using their default constructor (equivalent to a null pointer) and then to assign them later to a copy of the expression passed to [macroref BOOST_CONTRACT_OLDOF] in a nullary functor [^['d]]`()` passed to `.old(`[^['d]]`)`. -The functor [^['d]]`()` is called by this library before the function body is executed but only after class invariants and preconditions are checked: -[footnote -*Rationale:* -Functors for preconditions, old value assignments, postconditions, and exception guarantees are all optional but when specified, they must be specified in that order. -Such order is enforced by the fact that [classref boost::contract::specify_precondition_old_postcondition_except], [classref boost::contract::specify_old_postcondition_except], [classref boost::contract::specify_postcondition_except], [classref boost::contract::specify_except], and [classref boost::contract::specify_nothing] provide a progressively decreasing subset of the `.precondition(...)`, `.old(...)`, `.postcondition(...)`, and `.except(...)` member functions. -The enforced order for specifying preconditions, old value assignments, postconditions, and exception guarantees makes logical sense because it follows the order at which these are executed at run-time. -Other contract programming frameworks allow to mix this order, that could have been implemented for this library as well but it would have complicated somewhat the library implementation while adding no real value (arguably creating confusion in user code by not enforcing a consistent order for specifying contract conditions). -] -

... - }) - .except([&] { - BOOST_CONTRACT_ASSERT(*old_``[^['name]]`` ...); // Never null here. - ... - }) - ; - -For example, the following old value expression `s[index]` passed to [macroref BOOST_CONTRACT_OLDOF] is valid only after the precondition has checked that `index` is within valid range `index < s.size()`. -Therefore, `old_y` is first declared using its default constructor (i.e., initialized to a null pointer) and later assigned to a copy of `s[index]` in `.old(...)` after the precondition has checked `index` (see [@../../example/features/old.cpp =old.cpp=]): - -[import ../example/features/old.cpp] -[old] - -The functor passed to `.old(...)` should capture all variables it needs to evaluate to copy the old value expressions passed to [macroref BOOST_CONTRACT_OLDOF]. -In general, these variables should be captured by reference and not by value (because old values need to make copies of the values the captured variables will have just before executing the function body, and not copy the values these variables had when the functor passed to `.old(...)` was first declared). -In any case, the functor passed to `.old(...)` should modify only old values and not the values of other captured variables (see __Constant_Correctness__). - -This library will automatically call the failure handler [funcref boost::contract::old_failure] if calling the functor specified via `.old(...)` throws an exception (by default, this handler prints an error message to `std::cerr` and terminates the program calling `std::terminate`, but see __Throw_on_Failure__ to throw exceptions, exit the program with an error code, etc.). - -[note -If old value pointers are initialized at the point of their construction instead of using `.old(...)` then an exception thrown by the old value expression passed to [macroref BOOST_CONTRACT_OLDOF], or more in general any exception thrown by the old value pointer initialization, will result in that exception being thrown up the stack by the enclosing function. -This is arguably less correct than calling [funcref boost::contract::old_failure] because an exception thrown by an old value copy causes the program to fail checking its postconditions and exception guarantees but should not automatically causes the enclosing function to thrown an exception (this might not be a significant difference in practice, but it could be an additional reason to use `.old(...)` instead of copying old values when they are declared before the contract). -[footnote -*Rationale:* -It would be possible to wrap all old value operations ([classref boost::contract::old_ptr] copy constructor, [funcref boost::contract::make_old], etc.) in try-catch statements so this library will call [funcref boost::contract::old_failure] also when old values are copied when they are constructed outside `.old(...)`. -However, that will prevent this library from knowing the [enumref boost::contract::from] parameter and that would be problematic (specifically because destructors can have postconditions so that parameter is necessary to make sure user-defined failure handlers can be programmed to never throw from destructors as C++ usually requires). -] -] - -[endsect] - -[section Named Overrides] - -The function names passed to [macroref BOOST_CONTRACT_OVERRIDE] and [macroref BOOST_CONTRACT_OVERRIDES] should never start with an underscore to avoid generating names containing double underscores `override__...` (which are reserved by the C++ standard). -There is a separate macro [macroref BOOST_CONTRACT_NAMED_OVERRIDE] that can be used to explicitly specify the name of the type that will be passed to [funcref boost::contract::public_function] as a template argument: -[footnote -*Rationale:* -A different macro [macroref BOOST_CONTRACT_NAMED_OVERRIDE] is used instead of overloading [macroref BOOST_CONTRACT_OVERRIDE] using variadic macros because the override macros cannot be programmed manually by users so making it a variadic would prevent to use this library on compilers that do not support variadic macros (see __No_Macros__). -] - - BOOST_CONTRACT_OVERRIDE(``[^['function-name]]``) // Generate `override_...`. - BOOST_CONTRACT_NAMED_OVERRIDE(``[^['type-name]]``, ``[^['function-name]]``) // Generate `type-name`. - -For example, the following public function override is named `_1` so `BOOST_CONTRACT_OVERRIDE(_1)` would generate a type named `override__1` (which is reserved in C++ because it contains double underscores `__`), `BOOST_CONTRACT_NAMED_OVERRIDE(override1, _1)` is used to name the type `override1` instead (see [@../../example/features/named_override.cpp =named_override.cpp=]): -

-Note that there is not a `BOOST_CONTRACT_NAMED_OVERRIDES` macro so [macroref BOOST_CONTRACT_NAMED_OVERRIDE] needs to be invoked separately on each function name (there is instead a [macroref BOOST_CONTRACT_OVERRIDES] macro as seen in __Public_Function_Overrides__). -[footnote -*Rationale:* -The syntax for invoking a possible `BOOST_CONTRACT_NAMED_OVERRIDES` macro would need to be something like `BOOST_CONTRACT_NAMED_OVERRIDES(`[^['type-name1]]`, `[^['function-name1]]`, `[^['type-name2]]`, `[^['function-name2]]`, ...)`. -The authors felt this syntax is less readable than repeating single `BOOST_CONTRACT_NAMED_OVERRIDE` invocations `BOOST_CONTRACT_NAMED_OVERRIDE(`[^['type-name1]]`, `[^['function-name1]]`) BOOST_CONTRACT_NAMED_OVERRIDE(`[^['type-name2]]`, `[^['function-name2]]`) ...` so decided not to provide the `BOOST_CONTRACT_NAMED_OVERRIDES` macro. -] -

-This section gives an overview of Contract Programming (see __Meyer97__, __Mitchell02__, and __N1613__ for more detailed introductions to Contract Programming). -Readers that already have a basic understanding of Contract Programming can skip this section and maybe come back to it after reading the __Tutorial__. - -[note -The objective of this library is not to convince programmers to use Contract Programming. -It is assumed that programmes understand the benefits and trade-offs associated with Contract Programming and they have already decided to use this methodology in their code. -Then, this library aims to be the best and more complete Contract Programming library for C++ (that does not use preprocessors and other tools external to the C++ preprocessor and language itself). -] - -[section Assertions] - -Contract Programming is characterized by the following assertion mechanisms: - -* /Preconditions/: These are logical conditions that programmers expect to be true when a function is called (e.g., to check constraints on function arguments). -Operations that logically have no preconditions (i.e., that are always well-defined for the entire domain of their inputs) are often referred to as having a /wide contract/. -This is in contrast to operations that have preconditions which are often referred to as having a /narrow contract/ (note that operations with truly narrow contracts should not even throw exceptions). -[footnote -The nomenclature of wide and narrow contracts has gained some popularity in recent years in the C++ community (appearing in a number of more recent proposals to add contract programming to the C++ standard, see __Bibliography__). -This nomenclature is perfectly reasonable but it is not often used in this document because the authors generally prefer to explicit mention "this operation has no preconditions..." or "this operation has preconditions...". -] -* /Postconditions/: These are logical conditions that programmers expect to be true when a function exits without throwing an exception (e.g., to check the result and any side effect that a function might have). -Postconditions can access the function return value (for non-void functions) and /old values/ that expressions had before the function body was executed. -* /Exception guarantees/: These are logical conditions that programmers except to be true when a function exits throwing an exception. -Exceptions specifications can access old values (but not the function return value). -[footnote -*Rationale:* -Contract assertions for exception guarantees were first introduced by this library (even if exception safety guarantees have long been part of C++ STL documentation). -Contract assertions for exception safety guarantees are not part of __N1962__ or other references listed in the __Bibliography__. -] -* /Class invariants/: These are logical conditions that programmers expect to be true after a constructor exits without throwing an exception, before and after the execution of every non-static public non-static function (even if they throw exceptions), before the destructor is executed and if the destructor throws an exception (i.e., class invariants define valid states for all objects of a given class). -It is possible to specify a different set of class invariants for volatile public functions, namely /volatile class invariants/. -It is also possible to specify /static class invariants/ which are excepted to be true before and after the execution of any constructor, destructor (even if it does not throw an exception), and public function (even if static). -[footnote -*Rationale:* -Static and volatile class invariants were first introduced by this library to reflect the fact that C++ supports both static and volatile public functions. -Static and volatile class invariants are not part of __N1962__ or other references listed in the __Bibliography__. -] -* /Subcontracting/: This indicates that preconditions cannot be strengthen, while postconditions and class invariants cannot be weaken when a public function in a derived class overrides public functions in one or more of its base classes (this is formally defined according to the __substitution_principle__). - -Class invariants can also be used to specify /basic/ exception safety guarantees for an object (because they are checked at exit of public functions even when those throw an exception), while contract assertions for exception guarantees can be used to specify /strong/ exception safety guarantees for given operations on the same object. - -It is also a common requirement for Contract Programming to automatically disable contract checking while already checking assertions from another contract (in order to avoid infinite recursion while checking contract assertions). - -[note -This library implements this requirement but in order to globally disable assertions while checking another assertion some kind of global arbitrating variable needs to be used by this library implementation. -This library will automatically protect such a global variable from race conditions in multi-threated programs, but this will effectively introduce a global lock in the program (the [macroref BOOST_CONTRACT_DISABLE_THREADS] macro can be defined to disable this global lock but at the risk of incurring in race conditions). -[footnote -*Rationale:* -[macroref BOOST_CONTRACT_DISABLE_THREADS] is named after `BOOST_DISABLE_THREADS`. -] -] - -In general, it is recommended to specify different contract conditions using separate assertion statements and not to group them together into a single condition using logical operators (`&&`, `||`, etc.). -This is because when contract conditions are programmed together in a single assertion using logical operators, it is not be clear which condition actually failed in case the entire assertion fails at run-time. - -[heading C-Style Assertions] - -A limited form of Contract Programming is the use of the C-style `assert` macro. -Using `assert` is common practice for many programmers but it suffers of the following limitations: - -* `assert` does not distinguish between preconditions and postconditions. -In well-tested production code, postconditions can usually be disabled trusting the correctness of the implementation while preconditions might still need to remain enabled because of possible changes in the calling code (e.g., postconditions of a given library could be disabled after testing while its preconditions can be kept enabled given the library cannot predict the evolution of user code that will be calling it). -Using `assert` it is not possible to selectively disable only postconditions and all assertions must be disabled at once. -* `assert` requires to manually program extra code to check class invariants (extra member functions, try blocks, etc.). -* `assert` does not support subcontracting. -* `assert` calls are usually scattered within function implementations thus the asserted conditions are not immediately visible in their entirety by programmers (as they are instead when the assertions appear in the function declaration or at least at the very top of function definition). - -Contract Programming does not suffers of these limitations. - -[endsect] - -[section Benefits and Costs] - -[heading Benefits] - -The main use of Contract Programming is to improve software quality. -__Meyer97__ discusses how Contract Programming can be used as the basic tool to write ["correct] software. -__Stroustrup94__ discusses the key importance of class invariants plus advantages and disadvantages of preconditions and postconditions. -The following is a short summary of the benefits associated with Contract Programming inspired mainly by __N1613__: - -* Preconditions and postconditions: -Using function preconditions and postconditions, programmers can give a precise semantic description of what a function requires at its entry and what it ensures at its exit (if it does not throw an exception). -In particular, using postcondition old values, Contract Programming provides a mechanism that allows programmers to compare values of an expression before and after the function body execution. -This mechanism is powerful enough to enable programmers to express many correctness constraints within the code itself, constraints that would otherwise have to be captured at best only informally by documentation. -* Class invariants: -Using class invariants, programmers can describe what to expect from a class and the logic dependencies between the class members. -It is the job of the constructor to ensure that the class invariants are satisfied when the object is first created. -Then the implementation of the member functions can be largely simplified as they can be written knowing that the class invariants are satisfied because Contract Programing checks them before and after the execution of every public function. -Finally, the destructor makes sure that the class invariants held for the entire life of the object checking the class invariants one last time before the object is destructed. -Class invariants can also be used as a criterion for good abstraction: If it is not possible to specify an invariant, it might be an indication that the design abstraction maybe be poor and it should not have been made into a class. -* Self-documenting code: -Contracts are part of the source code, they are checked at run-time so they are always up-to-date with the code itself. -Therefore program specifications, as documented by the contracts, can be trusted to always be up-to-date with the implementation. -* Easier debugging: -Contract Programming can provide a powerful debugging facility because, if contracts are well written, bugs will cause contract assertions to fail exactly where the problem first occurs instead than at some later stage of the program execution in an apparently unrelated (and often hard to debug) manner. -Note that a precondition failure points to a bug in the function caller, a postcondition failure points instead to a bug in the function implementation. -[footnote -Of course, if contracts are ill-written then Contract Programming is of little use. -However, it is less likely to have a bug in both the function body and the contract than in the function body only. -For example, consider the validation of a result in postconditions. -Validating the return value might seem redundant, but in this case we actually want that redundancy. -When programmers write a function, there is a certain probability that they make a mistake in implementing the function body. -When programmers specify the result of the function in the postconditions, there is also a certain probability that they make a mistake in writing the contract. -However, the probability that programmers make a mistake twice (in both the body /and/ the contract) is in general lower than the probability that the mistake is made just once (in either the body or the contract). -] -* Easier testing: -Contract Programming facilitates testing because a contract naturally specifies what a test should check. -For example, preconditions of a function state which inputs cause the function to fail and postconditions state which outputs are produced by the function on successful exit (Contract Programming should be seen as a tool to complement, but obviously not to replace, testing). -* Formal design: -Contract Programming can serve to reduce the gap between designers and programmers by providing a precise and unambiguous specification language in terms of the contract assertions. -Moreover, contracts can make code reviews easier by clarifying some of the semantics and usage of the code. -* Formalized inheritance: -Contract Programming formalizes the virtual function overriding mechanism using subcontracting as justified by the __substitution_principle__. -This keeps the base class programmers in control as overriding functions always have to fully satisfy the contracts of their base classes. -* Replace Defensive Programming: -Contract Programming assertions can replace [@http://en.wikipedia.org/wiki/Defensive_programming Defensive Programming] checks localizing these checks within the contract and making the code more readable. - -Of course, not all formal contract specifications can be asserted in C++. -For example, in C++ is it not possible to assert the validity of an iterator range in the general case because the only way to check if two iterators form a valid range is to keep incrementing the first iterator until we reach the second iterator. -However, in case the iterator range is invalid, such a code would render undefined behaviour or run forever instead of failing an assertion. -Nevertheless, a large amount of contract assertions can be successfully programmed in C++ as illustrated by the numerous examples in this documentation and from the literature (for example see how much of STL [link N1962_vector_anchor `vector`] contract assertions can actually be programmed in C++ using this library). - -[heading Costs] - -In general, Contract Programming benefits come at the cost of performance as discussed in detail by both __Stroustrup94__ and __Meyer97__. -While performance trade-offs should be carefully considered depending on the specific application domain, software quality cannot be sacrificed: It is difficult to see value in software that quickly and efficiently provides incorrect results. - -The run-time performances are negatively impacted by Contract Programming mainly because of extra time require to: - -* Check the asserted conditions. -* Copy old values when these are used in postconditions and exception guarantees. -* Call additional functors that check preconditions, postconditions, exception guarantees, class invariants, etc. (especially for subcontracting). - -[note -In general, contracts introduce at least three extra functor calls to check preconditions, postconditions, and exception guarantees for any given non-member function call. -Public functions introduce also two more function calls to check class invariants (at entry and at exit). -For subcontracting, these extra calls (some of which become virtual calls) are repeated for the number of functions being overridden from the base classes (possibly deep in the inheritance tree). -In addition to that, this library introduces a number of function calls internal to its implementation in order to properly check the contracts. -] - -To mitigate the run-time performance impact, programmers can selectively disable run-time checking of some of the contract assertions. -Programmers will have to decide based on the performance trade-offs required by their applications, but a reasonable approach often is to (see __Disable_Contract_Checking__): - -* Always write contracts to clarify the semantics of the design embedding the specifications directly in the code and making the code self-documenting. -* Check preconditions, postconditions, class invariants, and maybe even exception guarantees during initial testing. -* Only check preconditions (and maybe class invariants, but not postconditions and exception guarantees) during release testing and for the final release. - -This approach is usually reasonable because in well-tested production code, validating the function body implementation using postconditions is rarely needed since the function has shown itself to be ["correct] during testing. -On the other hand, checking function arguments using preconditions is always needed because of changes that can be made to the calling code (without having to necessarily re-test and re-release the called code). -Furthermore, postconditions and also exception guarantees, with related old value copies, are often computationally more expensive to check than preconditions and even class invariants. - -[endsect] - -[section Function Calls] - -[heading Non-Member Functions] - -A call to a non-member function with a contract executes the following steps (see [funcref boost::contract::function]): - -# Check function preconditions. -# Execute the function body. -# If the body did not throw an exception, check function postconditions. -# Else, check function exception guarantees. - -[heading Private and Protected Functions] - -In Contract Programming, private and protected functions do not have to satisfy the class invariants because these functions are part of the class implementation and not of the class public interface. -Furthermore, the __substitution_principle__ does not apply to private and protected functions because these functions are not accessible to the user at the calling site where the __substitution_principle__ applies. - -Therefore, calls to private and protected functions with contracts execute the same steps as the ones indicated above for non-member functions (checking only preconditions and postconditions, but without checking class invariants and without subcontracting). - -[endsect] - -[section Public Function Calls] - -[heading Overriding Public Functions] - -Let's consider a public function in a derived class that overrides public virtual functions declared in a number of its public base classes (because of C++ multiple inheritance, the function could override from more than one base class). -We refer to the function in the derived class as the /overriding function/, and to the set of base classes containing all the /overridden functions/ as /overridden bases/. - -When subcontracting, overridden functions are searched (at compile-time) deeply in the public branches of the inheritance tree (i.e., not just the derived class's direct public parents are inspected, but also all its public grandparents, etc.). -In case of multiple inheritance this search also extends widely to all multiple public base classes following their order of declaration in the derived class inheritance list (as usual in C++, this search could result in multiple overridden functions and therefore in subcontracting from multiple public base classes). -Note that only public base classes are considered for subcontracting because private and protected base classes are not accessible to the user at the calling site where the __substitution_principle__ applies. - -A call to the overriding public function with a contract executes the following steps (see [funcref boost::contract::public_function]): - -# Check static class invariants __AND__ non-static class invariants for all overridden bases, __AND__ then check the derived class static __AND__ non-static invariants. -# Check preconditions of overridden public functions from all overridden bases in __OR__ with each other, __OR__ else check the overriding function preconditions in the derived class. -# Execute the overriding function body. -# Check static class invariants __AND__ non-static class invariants for all overridden bases, __AND__ then check the derived class static __AND__ non-static invariants (even if the body threw an exception). -# If the body did not throw an exception, check postconditions of overridden public functions from all overridden bases in __AND__ with each other, __AND__ then check the overriding function postconditions in the derived class. -# Else, check exception guarantees of overridden public functions from all overridden bases in __AND__ with each other, __AND__ then check the overriding function exception guarantees in the derived class. -

-[note -Given that C++ allows destructors to throw, this library handles the case when the destructor body throws an exception as indicated above. -However, in order to comply with STL exception safety guarantees and good C++ programming practices, programmers should implement destructor bodies to rarely, if ever, throw exceptions (in fact destructors are declared `noexcept` by default in C++11). -] - -[endsect] - -[section Constant-Correctness] - -Contracts should not be allowed to modify the program state because they are only responsible to check (and not to change) the program state in order to verify its compliance with the specifications. -Therefore, contracts should only have access to the object, function arguments, function return value, old values, and all other program variables in `const` context (via `const&`, `const* const`, `const volatile`, etc.). - -Whenever possible (e.g., class invariants and postcondition old values), this library automatically enforces this constant-correctness constraint at compile-time using `const`. -However, this library cannot automatically enforce this constraint in all cases (for preconditions and postconditions of mutable member functions, for global variables, etc.). -See __No_Lambda_Functions__ for ways of using this library that always and automatically enforce the constant-correctness constraint at compile-time (but these methods require a significant amount of boiler-plate code to be programmed manually so they are not recommended in general). - -[important -In general, it is the responsibility of the programmers to code assertions that only check, and do not change, program variables. -[footnote -Note that also when using C-style `assert` it is the responsibility of the programmers to code assertions that only check and do not change program variables. -] -] - -[endsect] - -[section Specification vs. Implementation] - -Contracts are part of the program specification and not of its implementation. -Therefore, contracts should ideally be programmed within C++ declarations, and not within definitions. - -In general, this library cannot satisfy this requirement. -However, even when the contracts are programmed together with the body in the function definition, it is still very easy for users to identify and read just the contract portion of the function definition (because the contract code must always be programmed at the very top of the function definition). -See __Separate_Body_Implementation__ for ways of using this library to program contract specifications outside of the body implementation but at the cost of writing one extra function for any given function (for applications were this requirement is truly important). - -Furthermore, contracts are most useful when they assert conditions only using public members (in most cases, the need for using non-public members to check contracts, especially in preconditions, indicates an error in the class design). -For example, the caller of a public function cannot in general make sure that the function preconditions are satisfied if the precondition assertions use private members that are not callable by the caller (therefore, a failure in the preconditions will not necessarily indicate a bug in the caller given that the caller was made unable to fully check the preconditions in the first place). - -However, given that C++ provides programmers ways around access level restrictions (`friend`, function pointers, etc.), this library leaves it up to the programmers to make sure that only public members are used in contract assertions (especially in preconditions). (__N1962__ follows the same approach not restricting contracts to only use public members, Eiffel instead generates a compile-time error if preconditions are asserted using non-public members.) -[footnote -*Rationale:* -If C++ [@http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#45 defect 45] had not been fixed, this library could have been implemented so to generate a compile-time error when precondition assertions use non-public members more similarly to Eiffel's implementation (but not necessary the best approach for C++). -] - -[endsect] - -[section On Contract Failure] - -If precondition, postcondition, exception guarantee, or class invariant assertions are either checked to be false or their evaluation throws an exception at run-time then this library will call specific /failure handler functions/. - -By default, these failure handler functions print a message to the standard error `std::cerr` (with detailed information about the failure) and then terminate the program calling `std::terminate`. -However, using [funcref boost::contract::set_precondition_failure], [funcref boost::contract::set_postcondition_failure], [funcref boost::contract::set_except_failure], [funcref boost::contract::set_invariant_failure], etc. programmers can define their own failure handler functions that can take any user-specified action (throw an exception, exit the program with an error code, etc., see __Throw_on_Failure__). -[footnote -*Rationale:* -This customizable failure handling mechanism is similar to the one used by C++ `std::terminate` and also to the one proposed in __N1962__. -] - -[note -In C++ there are a number of issues with programming contract failure handlers that throw exceptions instead of terminating the program. -Specifically, destructors check class invariants so they will throw if programmers change class invariant failure handlers to throw instead of terminating the program, but in general destructors should not throw in C++ (to comply with STL exception safety, etc.). -Furthermore, programming an exception guarantee failure handler to throw will throw an exception (the one reporting the contract failure) while there is already an active exception (the one that caused the exception guarantees to be checked in the first place), and this will force C++ to terminate the program anyway. -] - -Therefore, it is recommended to terminate the program at least for contract failures from destructors and exception guarantees (if not in all other cases of contract failures as it is done by default by this library). -The contract failure handler functions programmed using this library have information about the failed contract (preconditions, postconditions, etc.) and the operation that was checking the contract (constructor, destructor, etc.) so programmers can granularly distinguish all cases and decide when it is appropriate to terminate, throw, or take some other user-specific action. - -[endsect] - -[section Feature Summary] - -The Contract Programming features supported by this library are largely based on __N1962__ and on the Eiffel programming language. -The following table compares Contract Programming features among this library, __N1962__ (unfortunately the C++ standard committee rejected this proposal commenting on a general lack of need for adding Contract Programming to C++ at the time, even if __N1962__ itself is sound), a more recent proposal __P0380__ (which unfortunately only supports preconditions and postconditions, but does not support class invariants, old values, and subcontracting), the Eiffel and D programming languages: -

-However, in some other cases it might be desirable to skip assertions that use old values when the respective old value types are not copyable. -Programmers can do this by using [classref boost::contract::old_ptr_if_copyable] instead of [classref boost::contract::old_ptr] to program these old values and by checking if the old value pointer is not null before dereferencing it in postconditions. -For example, consider the following function template that could in general be instantiated for types `T` that are not copy constructible (that is for which [classref boost::contract::is_old_value_copyable]`::value` is `false`, see [@../../example/features/old_if_copyable.cpp =old_if_copyable.cpp=]): -[footnote -*Rationale:* -__N1962__ and other proposals to add contracts to C++ do not provide a mechanism to selectively disable copies for only old value types that are not copy constructible. -However, this library provides such a mechanism to allow to program contracts for template code without necessarily adding extra copy constructible type requirements that would not be present if it were not for copying the old values (so compiling the code with and without contracts will not necessarily alter the type requirements of the program). -Something similar could be achieved combing C++17 `if constexpr` with __N1962__ or __P0380__ so that old value expressions within template code could be guarded by `if constexpr` statements checking if the old value types are copyable or not. -For example, assuming old values are added to __P0380__ (e.g., via `oldof`) and that C++17 `if constexpr` can be used within __P0380__ contracts: -`` -

-The old value pointer `old_x` is programmed using [classref boost::contract::old_ptr_if_copyable] so if `T` is not copyable then `x` will simply not be copied and `old_x` will be left as a null pointer (here `old_x` must be checked to be not null `if(old_x) ...` before it is dereferenced in postconditions and exception guarantees). -If the above example used [classref boost::contract::old_ptr] instead then the library would have generated a compile-time error when `offset` is instantiated with types `T` that are not copy constructible (but only if `old_x` is actually dereferenced somewhere in the contract assertions using `*old_x ...`, `old_x->...`, etc.). - -When C++11 `auto` declarations are used with [macroref BOOST_CONTRACT_OLDOF], this library always defaults to using the [classref boost::contract::old_ptr] type (because this type requirements are more stringent, if programmers want to relax the copyable type requirement they must do so explicitly by using [classref boost::contract::old_ptr_if_copyable] instead of using `auto`). -For example, the following will use [classref boost::contract::old_ptr] and not [classref boost::contract::old_ptr_if_copyable] to declare `old_x`: - - auto old_x = BOOST_CONTRACT_OLDOF(x); // C++11 auto declarations always use `old_ptr` (never `old_ptr_if_copyable`). - -This library internally uses [classref boost::contract::is_old_value_copyable] to determine if an old value type is copyable or not, and then [classref boost::contract::old_value_copy] to actually copy the old value. -By default, [classref boost::contract::is_old_value_copyable]`` is equivalent to `boost::is_copy_constructible` and [classref boost::contract::old_value_copy]`` is implemented using `T`'s copy constructor. -However, these type traits can be specialized by programmers for example to avoid making old value copies of types even when they have a copy constructor (maybe because these copy constructors are too expensive), or to make old value copies for types that do not have a copy constructor, or for any other specific need programmers might have for the types in question. -For example, the following specialization of [classref boost::contract::is_old_value_copyable] intentionally avoids making old value copies for all expressions of type `w` even if that type has a copy constructor (see [@../../example/features/old_if_copyable.cpp =old_if_copyable.cpp=]): -

-In some cases it might be acceptable, or even desirable, to cause a compile-time error when a program uses types that do not provide all the operations needed to check contract assertions (because it is not possible to fully check the correctness of the program as specified by its contracts). -In these cases, programmers can specify contract assertions as we have seen so far, compilation will fail if user types do not provide all operations necessary to check the contracts. - -However, in some other cases it might be desirable to not augment the type requirements of a program because of contract assertions and to skip these assertions when user types do not provide all the operations necessary to check them. -Programmers can do this by using [funcref boost::contract::condition_if] (or [funcref boost::contract::condition_if_c]). - -For example, let's consider the following `vector` class template. -This class template does not usually require that its type parameter `T` has an equality operator `==` (it only requires `T` to be copy constructible, see `std::vector` documentation). -However, the contracts for the `vector::push_back(value)` public function include a postcondition `back() == value` that introduces the new requirement that `T` must also have an equality operator `==`. -Programmers can specify this postcondition as usual with `BOOST_CONTRACT_ASSERT(back() == value)` an let the program fail to compile when users instantiate `vector` with a type `T` that does not provide an equality operator `==`. -Otherwise, programmers can specify this postcondition using [funcref boost::contract::condition_if] to evaluate the asserted condition only for types `T` that have an equality operator `==` (and trivially evaluate to `true` otherwise). -On C++17 compilers, the same can be achieved using `if constexpr` instead of [funcref boost::contract::condition_if] resulting in a more concise and readable syntax. -For example (see [@../../example/features/condition_if.cpp =condition_if.cpp=]): -

-[endsect] - -[section Move Operations] - -As with all public operations of a class, also move operations should maintain class invariants (see __Stroustrup13__, p. 520). -Specifically, C++ requires the following: - -* The moved-from object can be copy assigned. -* The moved-from object can be move assigned. -* The moved-from object can be destroyed (if not for anything else, this requires that class invariants are maintained by move operations because the destructor of the moved-from object requires class invariants to be satisfied at its entry, as always with destructors see __Destructor_Calls__). - -Therefore, both the move constructor and the move assignment operator need to maintain the class invariants of the moved-from object so their contracts can be programmed using [funcref boost::contract::constructor] and [funcref boost::contract::public_function] as always for constructors and public functions. -For example (see [@../../example/features/move.cpp =move.cpp=]): - -[import ../example/features/move.cpp] -[move] - -This example assumes that it is possible to call the public function `moved()` on the moved-from object. -This allows to make explicit the precondition that except for destructor, copy and move assignments all other public functions cannot be called on a moved-from object. -This precondition is usually implicit in C++ (i.e., documented by the standard but not checked by the language at run-time). -If it is is not possible (e.g., due to some optimized implementation of the move operations) to have such a `moved()` public function, the private `moved_` member (or similar) can be used to program class invariants and preconditions (and that will just relay on the usual implicit C++ assumption on moved-from object because users will not be able to fully check preconditions and class invariants before calling functions of a moved-from object). - -[note -The default move constructor and move assignment operator generated by C++ will not automatically check contracts. -Therefore, unless the move operations are not public or they have no preconditions, no postconditions, and their class has no invariants, programmers should manually define them using [funcref boost::contract::constructor], [classref boost::contract::constructor_precondition], and [funcref boost::contract::public_function] instead of relying on their default implementations generated by C++. -(Same as for all other operations automatically implemented by C++.) -] - -[endsect] - -[section Unions] - -In C++, a `union` cannot have virtual functions, bases classes, and cannot be used as a base class thus subcontracting ([classref boost::contract::virtual_], [macroref BOOST_CONTRACT_OVERRIDE], etc.) do not apply to unions. -Also a `union` cannot inherit from [classref boost::contract::constructor_precondition] (because it cannot have base classes) so such a class is used to declare a local object that checks constructor preconditions (at the very beginning of the constructor before old value copies and other contracts, see declaration of `pre` in the example below). -A part from that, this library is used as usual to program contracts for unions. -For example (see [@../../example/features/union.cpp =union.cpp=]): - -[import ../example/features/union.cpp] -[union] - -[endsect] - -[section Disable Contract Checking] - -Checking contracts adds run-time overhead and can slow down program execution (see __Benefits_and_Costs__). -Therefore, programmers can define any combination of the following macros (`-D` option in Clang and GCC, `/D` option in MSVC, etc.) to instruct this library to not check specific kind of contract conditions at run-time: - -* Define [macroref BOOST_CONTRACT_NO_PRECONDITIONS] to not check preconditions. -* Define [macroref BOOST_CONTRACT_NO_POSTCONDITIONS] to not check postconditions. -* Define [macroref BOOST_CONTRACT_NO_EXCEPTS] to not check exception guarantees. -* Define [macroref BOOST_CONTRACT_NO_ENTRY_INVARIANTS] to not check class invariants at call entry. -* Define [macroref BOOST_CONTRACT_NO_EXIT_INVARIANTS] to not check class invariants at call exit. -* Or, define [macroref BOOST_CONTRACT_NO_INVARIANTS] to not check class invariants at both call entry and exit. (This is provided for convenience, it is equivalent to define both [macroref BOOST_CONTRACT_NO_ENTRY_INVARIANTS] and [macroref BOOST_CONTRACT_NO_EXIT_INVARIANTS].) -* Define [macroref BOOST_CONTRACT_NO_CHECKS] to not run implementation checks (programmed using [macroref BOOST_CONTRACT_CHECK], etc.). - -[note -In general, old values are used by both postconditions and exception guarantees so it is necessary to define both [macroref BOOST_CONTRACT_NO_POSTCONDITIONS] and [macroref BOOST_CONTRACT_NO_EXCEPTS] to disable old value copies. -] - -By default, none of these macros are defined so this library checks all contracts. -When these macros are defined by the user, the implementation code of this library is internally optimized to minimize as much as possible any run-time and compile-time overhead associated with checking and compiling contracts (see __Disable_Contract_Compilation__ for techniques to completely remove any run-time and compile-time overhead associated with contract code). - -For example, programmers could decide to check all contracts during early development builds, but later check only preconditions and maybe entry invariants for release builds by defining [macroref BOOST_CONTRACT_NO_POSTCONDITIONS], [macroref BOOST_CONTRACT_NO_EXCEPTS], [macroref BOOST_CONTRACT_NO_EXIT_INVARIANTS], and [macroref BOOST_CONTRACT_NO_CHECKS]. - -[endsect] - -[section Assertion Levels] - -This library provides three predefined /assertion levels/ that can be used depending on the computational complexity of the asserted conditions: -[footnote -The assertion levels predefined by this library are similar to the default, audit, and axiom levels proposed in __P0380__. -] - -* [macroref BOOST_CONTRACT_ASSERT] is used to assert conditions that are not computationally expensive, at least compared to the cost of executing the function body. -These assertions are always checked at run-time and cannot be disabled. -* [macroref BOOST_CONTRACT_ASSERT_AUDIT] is used to assert conditions that are computationally expensive compared to the cost of executing the function body. -These assertions are not checked at run-time unless programmers explicitly define [macroref BOOST_CONTRACT_AUDITS] (undefined by default), but the conditions are always compiled and validated syntactically (even when they are not actually evaluated and checked at run-time). -* [macroref BOOST_CONTRACT_ASSERT_AXIOM] is used to assert conditions that are computationally prohibitive, at least compared to the cost of executing the function body. -These assertions are never evaluated or checked at run-time, but the asserted conditions are always compiled and validated syntactically so these assertions can serve as formal comments in the code. - -In addition, [macroref BOOST_CONTRACT_CHECK_AUDIT] and [macroref BOOST_CONTRACT_CHECK_AXIOM] are similar to [macroref BOOST_CONTRACT_ASSERT_AUDIT] and [macroref BOOST_CONTRACT_ASSERT_AXIOM] but they are used to program audit and axiom levels for implementation checks instead of assertions (see __Implementation_Checks__). - -For example, [macroref BOOST_CONTRACT_ASSERT_AUDIT] can be used to program computationally expensive assertions (see [@../../example/features/assertion_level.cpp =assertion_level.cpp=]): - -[import ../example/features/assertion_level.cpp] -[assertion_level_audit] - -Also [macroref BOOST_CONTRACT_AUDITS] can be used to disable expensive old value copies and related assertions that use them (see [@../../example/features/assertion_level.cpp =assertion_level.cpp=]): - -[assertion_level_class_begin] -[assertion_level_audit_old] -[assertion_level_class_end] - -The condition passed to [macroref BOOST_CONTRACT_ASSERT_AXIOM] is compiled but not actually evaluated at run-time so this macro can be used to program computationally prohibitive assertions but also assertions that cannot actually be programmed in C++ using functions that are declared but left undefined. -For example, (see [@../../example/features/assertion_level.cpp =assertion_level.cpp=]): - -[assertion_level_no_impl] -[assertion_level_class_begin] -[assertion_level_axiom] -[assertion_level_class_end] - -In addition to the assertion levels predefined by this library, programmers are free to define their own. -For example, the following macro could be used to program and selectively disable assertions that have exponential computational complexity `O(e^n)`: - - #ifdef NO_EXPONENTIALLY_COMPLEX_ASSERTIONS - // Following will compile but never actually evaluate `cond`. - #define EXP_ASSERTION(cond) BOOST_CONTRACT_ASSERT(true || (cond)) - #else - // Following will compile and also evaluate `cond`. - #define EXP_ASSERTION(cond) BOOST_CONTRACT_ASSERT(cond) - #endif - - ... - - EXP_ASSERTION(``[^['some-exponentially-complex-boolean-condition]]``); - -[endsect] - -[section Disable Contract Compilation (Macro Interface)] - -This library provides macros that can be used to completely disable compile-time and run-time overhead introduced by contracts but at the cost of manually programming `#ifndef` statements around contract code: - -* This library defines [macroref BOOST_CONTRACT_NO_CONSTRUCTORS] when contract checking is disabled for constructors. -* This library defines [macroref BOOST_CONTRACT_NO_DESTRUCTORS] when contract checking is disabled for destructors. -* This library defines [macroref BOOST_CONTRACT_NO_PUBLIC_FUNCTIONS] when contract checking is disabled for public functions. -* This library defines [macroref BOOST_CONTRACT_NO_FUNCTIONS] when contract checking is disabled for (non-public) functions. -* This library defines [macroref BOOST_CONTRACT_NO_OLDS] when old value copies are disabled. -* This library defines [macroref BOOST_CONTRACT_NO_ALL] when checks are disabled for all contracts above. - -These macros are not configuration macros and they should not be defined directly by the users (otherwise this library will generate a compile-time error). -Instead, these macros are automatically defined by this library when users define [macroref BOOST_CONTRACT_NO_PRECONDITIONS], [macroref BOOST_CONTRACT_NO_POSTCONDITIONS], [macroref BOOST_CONTRACT_NO_EXCEPTS], [macroref BOOST_CONTRACT_NO_INVARIANTS] (or [macroref BOOST_CONTRACT_NO_ENTRY_INVARIANTS] and [macroref BOOST_CONTRACT_NO_EXIT_INVARIANTS]), and [macroref BOOST_CONTRACT_NO_CHECKS] (see __Disable_Contract_Checking__). - -Alternatively, this library provides a macro-based interface [headerref boost/contract_macro.hpp] that can be used to completely disable compile-time and run-time overhead introduced by contracts. -This macro interface is usually preferred because more concise and easier to use than programming `#ifdef` statements by hand, but it can make compiler errors more cryptic (because all macro code expands on a single line in C++ so line numbers in compiler errors are less useful than usual) and it leave a bit of contract decorations in the code but at no measurable overhead (extra [classref boost::contract::virtual_]`*` parameter, call to [classref boost::contract::constructor_precondition] default constructor which does nothing, [macroref BOOST_CONTRACT_BASE_TYPES] `typedef`, and [classref boost::contract::access] friendship, see example below). - -The following examples show how to use both the macro interface and alternatively the `#ifdef` statements to completely disable compile-time and run-time overhead introduced by contracts (see [@../../example/features/ifdef_macro.cpp =ifdef_macro.cpp=] and [@../../example/features/ifdef.cpp =ifdef.cpp=]): - -[import ../example/features/ifdef_macro.cpp] -[import ../example/features/ifdef.cpp] -[table -[ [Macro Interface] [`#ifdef` Statements] ] -[ [[ifdef_macro_function]] [[ifdef_function]] ] -] - -The same can be used to disable contract code complication for private and protected functions. -The [macroref BOOST_CONTRACT_OLD_PTR_IF_COPYABLE] macro is provided to handle non-copyable old value types (equivalently to [classref boost::contract::old_ptr_if_copyable]). -For constructors, destructors, and public functions instead (see [@../../example/features/ifdef_macro.cpp =ifdef_macro.cpp=] and [@../../example/features/ifdef.cpp =ifdef.cpp=]): - -[table -[ [Macro Interface] [`#ifdef` Statements] ] -[ [[ifdef_macro_class]] [[ifdef_class]] ] -] - -Static class invariants can be programmed using [macroref BOOST_CONTRACT_STATIC_INVARIANT] and volatile class invariants using [macroref BOOST_CONTRACT_INVARIANT_VOLATILE] (these macros expand code equivalent to the `static void `[macroref BOOST_CONTRACT_STATIC_INVARIANT_FUNC]`()` and `void `[macroref BOOST_CONTRACT_INVARIANT_FUNC]`() const volatile` functions respectively). - -Macro code expands on a single line so using the macro interface will cause all assertions within a given set of preconditions, postconditions, exception guarantees, and class invariants to list the same line number in their error messages if they fail at run-time (but the assertion code will be listed as well and it should allow programmers to identify the specific assertion that failed). -In general, the authors do not recommend to use the macro interface and the `#ifdef` statements unless strictly necessary because they both make the contract code more verbose, less readable, and can cause cryptic error messages. - -That said, disabling contract as shown in __Disable_Contract_Checking__ will still leave the overhead of compiling contract code plus some small run-time overhead due to the initialization of old value pointers (even if those will be all null and no old value will be actually copied), the calls to the contract functions used to initialize [classref boost::contract::check] and [classref boost::contract::constructor_precondition] (even if those calls will be internally optimized by this library to essentially do nothing), etc. -For truly performance critical code for which even such small run-time overhead might not be acceptable, the macro interface (or the `#ifdef` statements) shown here can be used to completely disable compile-time and run-time overheads of contracts. -However, for such performance-critical code even the overhead of checking simple preconditions might be too much so it might be best to not program contracts for such performance-critical code all together. - -Therefore, in most cases the compile-time overhead of contracts should not represent an issue and it should be sufficient to disable contract checking at run-time as indicated in __Disable_Contract_Checking__. - -[endsect] - -[section Separate Body Implementation] - -Contracts are part of the program specification and not of its implementation (see __Specification_vs_Implementation__). -However, this library uses function definitions to program contracts so contract code appears together with the function implementation code. -This is not ideal (even if contracts programmed using this library will always appear at the very beginning of the function definition so programmers will easily be able to distinguish contract code from the rest of the function implementation code and this might not be real problem in practise). - -In some cases, it might be desirable to completely separate the contract code from the function implementation code. -For example, this could be necessary for software that ships only header files and compiled object files to its users. -If contracts are programmed in function definitions that are compiled in the object files, users will not be able to see the contract code to understand semantics and usage of the functions (again, this might not be a real problem in practice for example if contracts are already somehow extracted from the source code and presented as part of the documentation of the shipped software). - -In any case, when it is truly important to separate contracts from function implementation code, function implementations can be programmed in extra /body functions/ (e.g., named `..._body`) that are compiled in object files. -Function definitions that remain in header files instead will contain just contract code followed by calls the extra body functions. -This technique allows to keep the contract code in header files while separating the implementation code to object files but at the cost of manually programming an extra function declaration for the body function (and with the limitation that constructor member initialization lists must be programmed in header files because that is where constructors need to be defined to list the constructor contract code). - -For example, the following header file only contains function declarations, contract code, and constructor member initializations, but it does not contain the code implementing the function bodies (see [@../../example/features/separate_body.hpp =separate_body.hpp=]): - -[import ../example/features/separate_body.hpp] -[separate_body_hpp] - -Instead, the function bodies are implemented in a separate source file (see [@../../example/features/separate_body.cpp =separate_body.cpp=]): - -[import ../example/features/separate_body.cpp] -[separate_body_cpp] - -The same technique can be used for non-member, private, and protected functions, etc. - -[note -When contracts are programmed only in =.cpp= files and also all this library headers are `#include`d only from the =.cpp= files, then these =.cpp= files can be compiled disabling specific contract checking (for example, [macroref BOOST_CONTRACT_NO_POSTCONDITIONS], [macroref BOOST_CONTRACT_NO_EXCEPTS], and [macroref BOOST_CONTRACT_NO_EXIT_INVARIANTS], see __Disable_Contract_Checking__). -Then the code in these =.cpp= files will always have such contract checking disabled even when linked to some other user code that might have been compiled with a different set of contracts disabled (i.e., a different set of `BOOST_CONTRACT_NO_...` macros defined). -This technique might be useful to ship compiled object files (e.g., for a library) that will never check some contracts (e.g., postconditions, exception guarantees, and exit invariants) regardless of the definition of the `BOOST_CONTRACT_NO_...` macros used to compile code that links against the shipped object files. - -On the contrary, if contracts are programmed only in header files (e.g., using extra `..._body` functions as shown in this section) and this library headers are `#include`d only in these header files that are being shipped, then end users can enable or disables contract checking of the shipped code by defining the `BOOST_CONTRACT_NO_...` macros when they compile the shipped header files as part of their code. -This technique might be useful in other situations when programmers that ship code want to leave it up the their end users to decide which contracts of the shipped code should be checked at run-time. -] - -[endsect] - -[section No Lambda Functions (No C++11)] - -This section shows how to use this library without C++11 lambda functions. -This has some advantages: - -* It allows to use this library on compilers that do not support C++11 lambda functions (essentially most C++03 compilers can be used in that case, see __No_Macros__ to also avoid using variadic macros). -* Contract functions (i.e., the `..._precondition`, `..._old`, and `..._postcondition` functions in the example below) can be programmed to fully enforce constant-correctness and other contract requirements at compile-time (see __Constant_Correctness__). -[footnote -If C++ allowed lambda functions to capture variables by constant reference (for example using the syntax `[const&] { ... }` and `[const& `[^['variable-name]]`] { ... }`, see [@https://groups.google.com/a/isocpp.org/forum/#!topic/std-proposals/0UKQw9eo3N0]) also lambdas could be used to program contract functors that fully enforce __Constant_Correctness__ at compile-time. -Note that C++11 lambdas allow to capture variables by value (`[=] { ... }` and `[`[^['variable-name]]`] { ... }`), these value captures are `const` (unless the lambda is explicitly declared `mutable`) but they are not suitable to program postconditions and exception guarantees using this library (because those require capturing by reference, see __Postconditions__ and __Exception_Guarantees__), plus they introduce a copy of the captured value that might be too expensive in general and therefore not suitable for preconditions either. -] -* Code of the contract functions is separated from function body implementations (see __Separate_Body_Implementation__). -[footnote -Alternatively, on compilers that do not support C++11 lambda functions, [@http://www.boost.org/doc/libs/release/libs/local_function/doc/html/index.html Boost.LocalFunction] could be used to program the contract functors still within the function definitions (for example, see [@../../example/features/no_lambdas_local_func.cpp =no_lambda_local_func.cpp=]). -In general, such a code is less verbose than the example shown in this section that uses contract functions programmed outside of the original function definitions (about 30% less lines of code) but the contract code is hard to ready. -Other libraries could also be used to program the contract functors without C++11 lambda functions (Boost.Lambda, Boost.Fusion, etc.) but again all these techniques will result in contract code either more verbose, or harder to read and maintain than the code that uses C++11 lambda functions. -] - -However, not using C++11 lambda functions comes to the significant cost of having to manually program the extra contract function and related boiler-plate code. -For example (see [@../../example/features/no_lambdas.hpp =no_lambdas.hpp=] and [@../../example/features/no_lambdas.cpp =no_lambdas.cpp=]): - -[import ../example/features/no_lambdas.hpp] -[no_lambdas_hpp] - -[import ../example/features/no_lambdas.cpp] -[no_lambdas_cpp] - -If programmers also want to fully enforce all contract programming constant-correctness requirements at compile-time, they should follow these rules when programming the contract functions (see __Constant_Correctness__): - -* Precondition functions (i.e., the `..._precondition` functions in the example above) can take their arguments either by `const` value or by `const&`, and when they are member functions they should be either `static` or `const` functions. -* Postcondition functions (i.e., the `..._postcondition` functions in the example above) should take their arguments by `const&`, and when they are member functions they should be either `static` or `const` functions. -* Similarly, exception guarantee functions (not shown in the example above) should take their arguments by `const&`, and when they are member functions they should be either `static` or `const` functions. -* Old value functions (i.e., the `..._old` functions in the example above) should take their arguments by `const&` a part from old value pointers that should be taken by `&` (so only old value pointers can be modified), and when they are member functions they should be either `static` or `const` functions. -* Constructor precondition, old value, and exception guarantee functions should be `static` (because there is no valid object `this` if the constructor body does not run successfully, see __Constructor_Calls__). -* Destructor postcondition functions should be `static` (because there is no valid object `this` after the destructor body runs successfully, but exception guarantee functions do not have to be `static` since the object `this` is still valid because the destructor body did not run successfully, see __Destructor_Calls__). - -Note that the extra contract functions also allow to keep the contract code in the header file while all function bodies are implemented in a separate source file (including the constructor member initialization list, that could not be done with the techniques shown in __Separate_Body_Implementation__). -[footnote -In this example, `bind` was used to generate nullary functors from the contract functions. -As always with `bind`, `cref` and `ref` must be used to bind arguments by `const&` and `&` respectively, plus it might be necessary to explicitly `static_cast` the function pointer passed to `bind` for overloaded functions. -] -Also note that the contract functions can always be declared `private` if programmers need to exactly control the public members of the class (this was not done in this example only for brevity). - -The authors think this library is most useful when used together with C++11 lambda functions. - -[endsect] - -[section No Macros (and No Variadic Macros)] - -It is possible to specify contracts without using most of the macros provided by this library and programming the related code manually instead (the only macros that cannot be programmed manually are [macroref BOOST_CONTRACT_OVERRIDE], [macroref BOOST_CONTRACT_OVERRIDES], and [macroref BOOST_CONTRACT_NAMED_OVERRIDE]). - -[note -Some of this library macros are variadic macros, others are not (see below). -Variadic macros were officially added to the language in C++11 but most compilers have been supporting them as an extension for a long time, plus essentially all compilers that support C++11 lambda functions also support C++11 variadic macros (and this library might rarely be used without the convenience of C++11 lambda functions, see __No_Lambda_Functions__). -[footnote -Compilation times of this library were measured to be comparable between compilers that support variadic macros and compilers that do not. -(See also [macroref BOOST_CONTRACT_MAX_ARGS] on compilers that do not support variadic macros. -*Rationale:* [macroref BOOST_CONTRACT_MAX_ARGS] is named after `BOOST_FUNCTION_MAX_ARGS`.) -] -Therefore, the rest of this section can be considered mainly a curiosity because programmers should seldom need to use this library without using its macros. -] - -[heading Overrides] - -As shown in __Public_Function_Overrides__ and __Named_Overrides__, this library provides the [macroref BOOST_CONTRACT_OVERRIDE] and [macroref BOOST_CONTRACT_NAMED_OVERRIDE] macros to program contracts for overriding public functions. -These macros cannot be programmed manually but they are not variadic macros so programmers should be able to use them on all C++ compilers. -[footnote -*Rationale:* -These macros expand SFINAE-based introspection templates that are too complex to be programmed manually by users (that remains the case even if C++14 generic lambdas were to be used here). -On a related note, in theory using C++14 generic lambdas, the [macroref BOOST_CONTRACT_OVERRIDE] macro could be re-implemented in a way that can be expanded at function scope, instead of class scope (but there is not really a need for that). -] -The [macroref BOOST_CONTRACT_OVERRIDES] macro is a variadic macro instead but programmes can manually repeat the non-variadic macro [macroref BOOST_CONTRACT_OVERRIDE] for each overriding public function name on compilers that do not support variadic macros. - -[heading Assertions (Not Variadic)] - -As shown in __Preconditions__, __Postconditions__, __Exception_Guarantees__, __Class_Invariants__, etc. this library provides the [macroref BOOST_CONTRACT_ASSERT] macro to assert contract conditions. -This is not a variadic macro and programmers should be able to use it on all C++ compilers. -In any case, the invocation `BOOST_CONTRACT_ASSERT(`[^['condition]]`)` expands to code equivalent to the following: -[footnote -*Rationale:* -No need to also support C++11 `__func__` because this will always expand to the name of `operator()` of the functor used to program the contract assertions (e.g., of the lambda function) and it will not expand to the name of the actual function specifying the contract. -] - - if(!(``[^['condition]]``)) { - throw boost::contract::assertion_failure(__FILE__, __LINE__, - BOOST_PP_STRINGIZE(``[^['condition]]``)); - } - -In fact, this library considers any exception thrown from within preconditions, postconditions, exception guarantees, and class invariants as a contract failure and reports it calling the related contract failure handler ([funcref boost::contract::precondition_failure], etc.). -If there is a need for it, programmers can always program contract assertions that throw specific user-defined exceptions as follow (see __Throw_on_Failure__): - - if(!``[^['condition]]``) throw ``[^['exception-object]]``; - -However, using [macroref BOOST_CONTRACT_ASSERT] is convenient because it always allows this library to show an informative message in case of assertion failure containing the assertion code, file name and line number, etc. - -The [macroref BOOST_CONTRACT_ASSERT_AUDIT] and [macroref BOOST_CONTRACT_ASSERT_AXIOM] macros are not a variadic macros and programmers should be able to use them on all C++ compilers. -Their implements are equivalent to the following: -

-[import ../example/features/base_types_no_macro.cpp] -[base_types_no_macro] - -The `base_types` member type must be a `boost::mpl::vector` which must list /all and only/ `public` base classes (because only public bases subcontract, see __Function_Calls__), and in the same order these public base classes appear in the derived class inheritance list. -If the [macroref BOOST_CONTRACT_BASE_TYPES] macro is not used, it is the responsibility of the programmers to maintain the correct list of bases in the `boost::mpl::vector` each time the derived class inheritance list changes (this might significantly complicate maintenance). - -In general, it is recommended to use the [macroref BOOST_CONTRACT_BASE_TYPES] macro whenever possible. - -[heading Old Values (Variadic)] - -As shown in __Old_Values__, this library provides the [macroref BOOST_CONTRACT_OLDOF] variadic macro to assign old value copies. -Programmers can also assign old values without using [macroref BOOST_CONTRACT_OLDOF] at the cost of writing a bit more code manually. -For example (see [@../../example/features/old_no_macro.cpp =old_no_macro.cpp=]): - -[import ../example/features/old_no_macro.cpp] -[old_no_macro] - -The ternary operator `boost::contract::copy_old(v) ? size() : boost::contract::null_old()` must be used here to avoid evaluating and copying the old value expression `size()` when [funcref boost::contract::copy_old] returns `false` (because old values are not being copied when postcondition and exception guarantees checking is disabled at run-time, an overridden virtual function call is not checking postconditions or exception guarantees yet, etc.). -The enclosing [funcref boost::contract::make_old] copies the old value expression and creates an old value pointer. -Otherwise, [funcref boost::contract::null_old] indicates that a null old value pointer should be created. -

-Some parts of this documentation use an operator [^['type-of](...)] to indicate an operator logically equivalent to C++11 `decltype(...)`. -However, this library implementation does not actually use type deduction in these cases (because the library already knows the types in question) so support for C++11 `decltype` and other type-of implementations are not actually required by this library (that is why [^['type-of]] and not the real `decltype` operator is used in this documentation). -

-[section Introduction] - -Contract Programming allows to specify preconditions, postconditions, and class invariants that are automatically checked when functions are executed at run-time. -These conditions assert program specifications within the source code itself allowing to find bugs more quickly during testing, making the code self-documenting, and increasing overall software quality (see __Contract_Programming_Overview__). - -For example, consider the following function `inc` that increments its argument `x` by `1` and let's write its contract using code comments (see [@../../example/features/introduction_comments.cpp =introduction_comments.cpp=]): - -[import ../example/features/introduction_comments.cpp] -[introduction_comments] - -The precondition states that at function entry the argument `x` must be strictly smaller than the maximum allowable value of its type (so it can be incremented by `1` without overflowing). -The postcondition states that at function exit the argument `x` must be incremented by `1` with respect to the /old value/ `x` had before executing the function indicated here by [^['oldof]`(x)` (note that postconditions shall be checked only when the execution of the function body did not throw an exception). - -Now let's program this function and its contract using this library (see [@../../example/features/introduction.cpp =introduction.cpp=] and __Non_Member_Functions__): - -[import ../example/features/introduction.cpp] -[introduction] - -When the above function `inc` is called, this library will: - -* First, execute the functor passed to `.precondition(...)` that asserts `inc` preconditions. -* Then, execute `inc` body (i.e., all the code that follows the `boost::contract::check c = ...` declaration). -* Last, execute the functor passed to `.postcondition(...)` that asserts `inc` postconditions (unless `inc` body threw an exception). - -For example, if there is a bug in the code calling `inc` so that the function is called with `x` equal to `std::numeric_limits::max()` then the program will terminate with an error message similar to the following (and it will be evident that the bug is in the calling code): - -[pre -precondition assertion "x < std::numeric_limits::max()" failed: file "introduction.cpp", line 17 -] - -Instead, if there is a bug in the implementation of `inc` so that `x` is not incremented by `1` after the execution of the function body then the program will terminate with an error message similar to the following (and it will be evident that the bug is in `inc` body): -[footnote -In this example the function body is composed of a single trivial instruction `++x` so it easy to check by visual inspection that it does not contain any bug and it will always increment `x` by `1` thus the function postcondition will never fail. -In real code, function bodies are rarely this simple and can hide bugs that make checking postconditions useful. -] - -[pre -postcondition assertion "x == *old_x + 1" failed: file "introduction.cpp", line 20 -] - -By default, when an assertion fails this library prints an error message such the ones above to the standard error `std::cerr` and terminates the program calling `std::terminate` (this behaviour can be customized to take any user-specified action including throwing exceptions, see __Throw_on_Failure__). -Note that the error messages printed by this library contain all the information necessary to easily and uniquely identify the point in the code at which the contract assertions fail. -[footnote -*Rationale:* -The assertion failure message printed by this library follows a format similar to the message printed by Clang when the C-style `assert` macro fails. -] - -[note -C++11 lambda functions are necessary to use this library without manually writing a significant amount of boiler-plate code to program the functors that assert the contracts (see __No_Lambda_Functions__). -Otherwise, this library does not use other C++11 features and should work on most modern C++ compilers (see __Getting_Started__). -] - -In addition to contracts for simple non-member functions as shown the in the example above, this library allows to program contracts for constructors, destructors, and member functions. -These can check class invariants and can also /subcontract/ inheriting and extending contracts from base classes (see [@../../example/features/introduction_public.cpp =introduction_public.cpp=] and __Public_Function_Overrides__): -[footnote -The `pushable` base class is used in this example just to show subcontracting, it is somewhat arbitrary and it will likely not appear in real code. -] - -[import ../example/features/introduction_public.cpp] -[introduction_public] - -[heading Language Support] - -The authors of this library advocate for contracts to be added to the core language. -Adding contract programming to the C++ standard has a number of advantages over any library implementation (shorter and more concise syntax to program contracts, specify contracts in declarations instead of definitions, enforce contract constant-correctness, expected faster compile- and run-time, vendors could develop static analysis tools to recognize and check contracts statically when possible, compiler optimizations could be improved based on contract conditions, etc.). - -Unfortunately, detailed and complete proposals to add contracts to the C++ standard such as __N1962__ were rejected by the C++ standard committee and it is not clear if the current proposal for adding contracts to C++ __P0380__ will actually be accepted by the standard. -[footnote -The authors find attractive the syntax that uses C++11 attributes `[[...]]` to specify contracts as indicated in __P0380__. -] -In any case, at least for now __P0380__ only supports pre- and postconditions while lacking basic features such as class invariants and old values in postconditions, not to mention the lack of more advanced features like subcontracting, all these features are instead supported by this library (see __Feature_Summary__ for a detailed comparison between the features supported by this library and the ones listed in different contract programming proposals, see __Bibliography__ for a list of references considered in designing and implementing this library including the vast majority of contract programming proposals submitted to the C++ standard committee). -

# The removed macros very hard to use because they required programmers to learn a domain-specific embedded language that replaced the usual C++ syntax for declaring functions and classes. - # The removed macros also made the code less readable, increased compilation time (because of extensive preprocessor meta-programming), and gave cryptic compiler errors. - # However, the removed macros more correctly specified contracts in code declarations instead of definitions, and they completely removed extra code when contracts were disabled (both of those can be done by the current version of this library but at the cost of manually writing some boiler-plate code which was previous automatically handled by the macros instead, see __Separate_Body_Implementation__ and __Disable_Contract_Compilation__). -# Simplified the library by removing some extra features that were not directly related to contract programming, specifically: - # Removed loop variants (because these are rarely if ever used). - # Removed named and deduced parameters (because these can be programmed directly using [@http://www.boost.org/doc/libs/release/libs/parameter/doc/html/index.html Boost.Parameter]). - # Removed concepts (because these can be programmed directly using [@http://www.boost.org/doc/libs/1_65_0/libs/concept_check/concept_check.htm Boost.ConceptCheck]). - # Removed emulation of virtual specifiers `override`, `final`, and `new` (because `override` can be programmed directly using C++11, while `final` and `new` are rarely if ever used). - # Removed `static_assert` emulation (because this can be programmed directly using C++11, or using [@http://www.boost.org/doc/libs/1_65_0/doc/html/boost_staticassert.html Boost.StaticAssert]). -# Ensuring that old values and return values are copied only once even when subcontracting is used with multiple inheritance. -# Improved template meta-programming algorithm that searches the inheritance tree for subcontracting when multiple inheritance is used. -# Exception specifications and function-try blocks apply also to exceptions thrown by the contracts, and not just to exceptions thrown by the body. -# Added contracts for exception guarantees (using `.except(...)`, etc.). -# Added predefined assertion levels for "audit" and "axiom". -# Added `call_if` and `condition_if` (assertions requirements were supported also by previous revisions of this library but they were handled by internal code generated by the contract macros). -

-August 20, 2012 - -Notes: - -# Using non-fix-spaced font in Full Table of Contents section. -# Added a couple of notes to the documentation. -# Changed `CONTRACT_MEMBER_BODY(class_type, function_name)` to `class_type::CONTRACT_MEMBER_BODY(function_name)` so the macro can also be used to declare derived classes avoiding using the library syntax even when the base class has contracts. -

-Notes: - -# Simplified syntax by reducing extra parenthesis to the bare necessary minimum (using some of the preprocessor parsing techniques originally introduced by Boost.LocalFunction). -# Postcondition old values only copy the old-of expression (e.g., copy just vector size instead of entire vector). -This improves performance and introduces the `ConstantCopyConstructible` requirement just for the old value expression type (e.g., a vector might not be copyable while its size always is because it is an integral type). -Removed the `copyable` tag. -# Body defined outside the macros (so compiler-errors for definitions retain their usual meaning). -# Added `CONTRACT_CLASS` macro and removed the need to duplicate declaration elements (do not repeat function declaration, do not repeat class name in function declaration, etc). -# Using `_TPL` macros so to reduce compile-time (instead of internally making all templates contract functions so to use `typename` freely). -# Overloading no longer requires unique parameter names. -# Added C++11-like virtual specifiers. -# Added constant assertions plus constant-expressions for select assertion if-conditions and for loop variants. -# Added named and deduced parameters. -# Added concept checking. -# Removed the interface to use the library without the macro (programmers were required to write too much boiler-plate code for the non-macro interface to be actually usable, plus supporting both the macro and non-macro interfaces limited what the macros could do). - -Released [@https://github.com/lcaminiti/boost-contract/tree/release/0_4_0 files] (e.g., select "Clone or download" and then "Download ZIP"). - -[endsect] - -[section Release 0.3.490] - -March 7, 2010 -

-Notes: - -# Removed use of `self`, `variable.now`, and `variable.old` in writing contracts. -Object `this` and variables are now accessed as usual in member functions. -`CONTRACT_OLDOF(variable)` is used to access old values in postconditions. -# Added `(precondition)`, `(postcondition)`, and `(body)` to specify contracts within the function signature sequence. -If no preconditions then `(precondition) ({...})` is simply omitted from the sequence (same for postconditions, body is mandatory instead). -For non-void functions, users can name the result argument with `(postcondition) (result-name) ({...})`. -# Changed contract class template to use same syntax as Boost.Function (i.e., `F` function type). -# Added support for free functions and static member functions. -# Added support for subcontracting with multiple inheritance. -# Added static class invariants which are always checked (also at constructors entry, destructor exit, and by static member functions). -# Added block invariants and Eiffel-like loop variants. -# Added handlers to customize action on contract failure (default to `std::terminate()`). -# Removed feature for automatic contract documentation using Doxygen (this is not compatible with added `(precondition)`, `(postcondition)`, and `(body)` because Doxygen preprocessor is not capable to handle Boost.Preprocessor sequences). -# Rewritten entire documentation (now using Boost.QuickBook instead of Doxygen). -

-Notes: - -# Compiled using both GCC (Linux and Cygwin) and MSVC (Windows XP). -# Required to use void to specify empty function argument list. -This is to comply with C++03 standard that does not allow to pass empty macro parameters so it does not support empty preprocessor sequences `()`. -

-[import ../example/features/non_member.cpp] -[non_member] - -All necessary header files of this library are included by `#include `. -Alternatively, programmers can selectively include only the header files they actually need among =boost/contract/*.hpp= (see __Getting_Started__). - -It is possible to specify preconditions, postconditions, and exception guarantees for non-member functions (see __Preconditions__, __Postconditions__, and __Exception_Guarantees__). - -The [funcref boost::contract::function] function returns an RAII object that must always be assigned to a local variable of type [classref boost::contract::check] (otherwise this library will generate a run-time error, see [macroref BOOST_CONTRACT_ON_MISSING_CHECK_DECL]). -[footnote -The name of this local variable is arbitrary, but `c` is often used in this documentation. -] -Furthermore, C++11 `auto` declarations cannot be used here and the [classref boost::contract::check] type must be explicitly specified (otherwise this library will generate a compile-time error). -The function body is programmed right after the declaration of the RAII object. - -[note -In some cases, it might be necessary to program some code before the contract. -For example for acquiring resources that will be used while checking the contract like old values, but also to lock mutexes (or other synchronization mechanisms) in multi-threaded programs. -] - -At construction, the [classref boost::contract::check] RAII object for non-member functions does the following (enclosing function entry): - -# Check preconditions, by calling the nullary functor [^['r]]`()` passed to `.precondition(`[^['r]]`)`. - -At destruction instead (enclosing function exit): - -# If the function body did not throw an exception: - # Check postconditions, by calling the nullary functor [^['s]]`()` passed to `.postcondition(`[^['s]]`)`. -# Else: - # Check exception guarantees, by calling the nullary functor [^['e]]`()` passed to `.except(`[^['e]]`)`. - -This ensures that non-member function contracts are correctly checked at run-time (see __Function_Calls__). -(Also note that functions will correctly check their contracts even when they are called via function pointers, function objects, etc.) - -[note -A non-member function can avoid calling [funcref boost::contract::function] for efficiency but only when it has no preconditions, no postconditions, and no exception guarantees. -] - -[endsect] - -[section Preconditions] - -When preconditions are specified, they are programmed using a functor [^['r]] passed to `.precondition(`[^['r]]`)` that can be called with no parameters as [^['r]]`()`. -Contracts that do not have preconditions simply do not call `.precondition(...)`. -Preconditions must appear before postconditions and exception guarantees when these are all present (see __Postconditions__ and __Exception_Guarantees__). - -C++11 lambda functions are convenient to program preconditions, but any other nullary functor can be used (see __No_Lambda_Functions__). -[footnote -Lambda functions with no parameters can be programmed in C++11 as `[...] () { ... }` but also equivalently as `[...] { ... }`. -This second from is often used in this documentation omitting the empty parameter list `()` for brevity. -] -For example, for [funcref boost::contract::function] (same for public functions, but destructors do not have preconditions and constructors use [classref boost::contract::constructor_precondition] instead, see __Destructors__ and __Constructors__): - - boost::contract::check c = boost::contract::function() // Same for all other contracts. - .precondition([&] { // Capture by reference or value... - BOOST_CONTRACT_ASSERT(...); // ...but should not modify captures. - ... - }) - ... - ; - -The precondition functor should capture all the variables that it needs to assert the preconditions. -These variables can be captured by value when the overhead of copying such variables is acceptable. -[footnote -In this documentation preconditions often capture variables by reference to avoid extra copies. -] -In any case, precondition assertions should not modify the value of the captured variables, even when those are captured by reference (see __Constant_Correctness__). - -Any code can be programmed in the precondition functor, but it is recommended to keep this code simple using mainly assertions and if-statements (to avoid programming complex preconditions that might be buggy and also slow to check at run-time). -It is also recommended to use [macroref BOOST_CONTRACT_ASSERT] to program precondition assertions because this enables the library to print informative error messages when the asserted conditions are evaluated to be false (this is not a variadic macro, see __No_Macros__): - - BOOST_CONTRACT_ASSERT(``/boolean-condition/``) - // Or, if boolean-condition contains commas `,` not already within parenthesis `()`... - BOOST_CONTRACT_ASSERT((``/boolean-condition/``)) // ...use extra parenthesis. - -This library will automatically call the failure handler [funcref boost::contract::precondition_failure] if any of the [macroref BOOST_CONTRACT_ASSERT] conditions are `false` and, more in general, if calling the functor specified to `.precondition(...)` throws any exception. -By default, this failure handler prints an error message to `std::cerr` and terminates the program calling `std::terminate` (see __Throw_on_Failure__ to change the failure handler to throw exceptions, exit the program with an error code, etc.). - -[note -Contracts are most useful when their assertions only use public members that are accessible to the caller so the caller can properly check and use the contract. -In particular, preconditions of a public function or constructor that use non-public members are essentially incorrect because they cannot be fully checked by the caller (in fact, Eiffel generates a compile-time error in this case). -However, this library does not enforce such a constraint and it leaves it up to programmers to only use public members when programming contracts, and especially when asserting preconditions (see __Specification_vs_Implementation__). -] - -[endsect] - -[section Postconditions] - -When postconditions are specified, they are programmed using a functor [^['s]] passed to `.postcondition(`[^['s]]`)` that can be called with no parameters as [^['s]]`()`. -Contracts that do not have postconditions simply do not call `.postcondition(...)`. -Postconditions must appear after preconditions but before exception guarantees when these are all present (see __Preconditions__ and __Exception_Guarantees__). -

-For non-void virtual public functions and public function overrides, the functor [^['s]] passed to `.postcondition(`[^['s]]`)` is not a nullary functor, instead it is a unary functor taking a variable holding the return value as its one parameter [^['s]]`(`[^['result]]`)` (this is to properly support subcontracting, see __Virtual_Public_Functions__ and __Public_Function_Overrides__). - -[endsect] - -[section Return Value] - -In non-void functions, postconditions can access the function return value to program assertions. -In this case, programmers are responsible to declare a local variable before the contract and to assign it to the return value at function exit (when the function does not throw an exception). -[footnote -The name of the local variable that holds the return value is arbitrary, but `result` is often used in this documentation. -] -For example, for [funcref boost::contract::function] (but same for all other contracts): - - ``/return-type/`` result; // Must be assigned to return value. - boost::contract::check c = boost::contract::function() // Same for all other contracts. - ... - .postcondition([&] { // Also capture `result` reference... - BOOST_CONTRACT_ASSERT(result ...); // ...but should not modify captures. - ... - }) - ... - ; - -At any point where the enclosing function returns, programmers are responsible to assign the result variable to the expression being returned. -This can be easily done by making sure that /all/ `return` statements in the function are of the form: - - return result = ``/expression/``; // Assign `result` at each return. - -The functor used to program postconditions should capture the result variable by reference and not by value (because postconditions must access the value the result variable will have at function exit, and not the value the result variable had when the postcondition functor was first constructed). -The return value should never be used in preconditions, old value copies, or exception guarantees (because the return value is not yet correctly evaluated and set when preconditions are checked, old values are copied, or if the function throws an exception). -In any case, programmers should not modify the result variable in the contract assertions (see __Constant_Correctness__). - -It is also possible to declared the result variable using `boost::optional` when the function return type does not have a default constructor, or if the default constructor is too expensive or undesirable to execute when declaring the result variable (see __Optional_Return_Value__). - -Non-void virtual public functions and public function overrides must always declare and use a result variable even when postconditions do not directly use the function return value (this is to properly support subcontracting, see __Virtual_Public_Functions__ and __Public_Function_Overrides__). - -[endsect] - -[section Old Values] - -When old values are used in postconditions or in exception guarantees, programmes are responsible to declare local variables before the contract and to assign them to related old value expressions using [macroref BOOST_CONTRACT_OLDOF]. -[footnote -The name of a local variable that holds an old value is arbitrary, but [^old_['variable-name]] is often used in this documentation. -] -For example, for [funcref boost::contract::function] (but same for all other contracts): - - boost::contract::old_ptr<``/type/``> old_``/name/`` = BOOST_CONTRACT_OLDOF(``/expression/``); - boost::contract::check c = boost::contract::function() // Same for all other contracts. - ... - .postcondition([&] { // Capture by reference... -

... - }) - ; - -Old values are handled by this library using the smart pointer class template [classref boost::contract::old_ptr] (so programmers do not directly manage allocation and deallocation of the pointed memory). -[footnote -*Rationale:* -Old values are optional values because they need to be left uninitialized in case postconditions and exception guarantees are disabled defining [macroref BOOST_CONTRACT_NO_POSTCONDITIONS] and [macroref BOOST_CONTRACT_NO_EXCEPTS] to avoid old value copies in that case (so a pointer or better a `boost::optional` can be used for that). -In addition, old values need to be pointers internally allocated by this library so that they are never copied twice even when calling an overridden function multiple times to check preconditions, postconditions, etc. to implement subcontracting (so a smart pointer class template was used). -] -The pointed old value is automatically qualified as `const` (so old values cannot be mistakenly changed by contract assertions, see __Constant_Correctness__). -This library ensures that old value pointers are always not null by the time postconditions and exception guarantees are checked (so programmers can safely dereference these pointers in postcondition and exception guarantee assertions using `operator*` or `operator->` without having to check if old value pointers are not null first). - -Old values should not be used in preconditions and this library does not guarantee that old value pointers are always not null when preconditions are checked. -[footnote -For example, old value pointers might be null in preconditions when postconditions and exception guarantees are disabled defining [macroref BOOST_CONTRACT_NO_POSTCONDITIONS] and [macroref BOOST_CONTRACT_NO_EXCEPTS], when checking an overridden virtual public function contract via subcontracting, and possibly in other cases. -] -See __Old_Copies_at_Body__ for delaying the assignment of old values until after class invariants (for constructors, destructors, and public functions) and preconditions are checked (this allows to program old value expressions under the simplifying assumption that class invariant and precondition assertions are satisfied already). - -[macroref BOOST_CONTRACT_OLDOF] is a variadic macro and it takes an extra parameter when used in virtual public functions or public function overrides (see __Virtual_Public_Functions__ and __Public_Function_Overrides__). -C++11 auto declarations can be used with [macroref BOOST_CONTRACT_OLDOF] for brevity `auto `[^old_['variable-name] = BOOST_CONTRACT_OLDOF(['expression])]. -See __No_Macros__ to program old values without using [macroref BOOST_CONTRACT_OLDOF] (e.g., on compilers that do not support variadic macros). - -[note -This library ensures that old values are copied only once. -This library also ensures that old values are never copied when postconditions and exception guarantees are disabled defining both [macroref BOOST_CONTRACT_NO_POSTCONDITIONS] and [macroref BOOST_CONTRACT_NO_EXCEPTS] (note that both these two macros must be defined, defining only [macroref BOOST_CONTRACT_NO_POSTCONDITIONS] or only [macroref BOOST_CONTRACT_NO_EXCEPTS] is not sufficient to prevent the run-time cost of old value copies). -] - -[endsect] - -[section Exception Guarantees] - -When exception guarantees are specified, they are programmed using a functor [^['e]] passed to `.except(`[^['e]]`)` that can be called with no parameters as [^['e]]`()`. -Contracts that do not have exception guarantees simply do not call `.except(...)`. -Exception guarantees must appear after both preconditions and postconditions when these are all present (see __Preconditions__ and __Postconditions__). - -C++11 lambda functions are convenient to program exception guarantees, but any other nullary functor can be used (see __No_Lambda_Functions__). -For example, for [funcref boost::contract::function] (but same for all other contracts): - - boost::contract::check c = boost::contract::function() // Same for all other contracts. - ... - .except([&] { // Capture by reference... - BOOST_CONTRACT_ASSERT(...); // ...but should not modify captures. - ... - }) - ; - -The exception guarantee functor should capture all variables that it needs to assert the exception guarantees. -In general, these variables should be captured by reference and not by value (because exception guarantees need to access the value that these variables will have when the function throws, and not the value these variables had when the exception guarantee functor was first constructed). -Exception guarantees can also capture old values (see __Old_Values__) but they should not access the return value instead (because the return value will not be properly set when the function throws an exception). -In any case, exception guarantee assertions should not modify the value of the captured variables (see __Constant_Correctness__). - -[note -In real code, it might be difficult to program meaningful exception guarantees without resorting to expensive old value copies that will slow down execution. -Therefore, the authors recognize that exception guarantees, even if supported by this library, might not be used often in practice (and they are not used in most of the examples listed in the rest of this documentation). -Instead, exception guarantees might be useful in those cases when they can be programmed just reusing the old value copies already present because used by postconditions. -] -

-[import ../example/features/base_types.cpp] -[base_types] - -For convenience, a local macro named `BASES` can be used to avoid repeating the base list twice (first in the derived class declaration `class `[^['class-name]]` : `[^['base-list]] and then again when invoking [macroref BOOST_CONTRACT_BASE_TYPES]`(`[^['base-list]]`)`). -Being a local macro, `BASES` must be undefined using `#undef BASES` after it has been used to declare `base_types` (to avoid name clashes and macro redefinition errors). -[footnote -The name of this local macro is arbitrary, but `BASES` is often used in this documentation. -] - -[macroref BOOST_CONTRACT_BASE_TYPES] is a variadic macro and accepts a list of bases separated by commas (see __No_Macros__ to program `base_types` without using macros). -As already noted in __Constructors__, when the extra base [classref boost::contract::constructor_precondition] is used to program constructor preconditions, its inheritance access level must always be `private` and it must be specified as the very first base. - -[important -Each base passed to [macroref BOOST_CONTRACT_BASE_TYPES] must /explicitly/ specify its inheritance access level `public`, `protected`, or `private` (but `virtual` is optional and can be specified either before or after the access level as usual in C++). -[footnote -*Rationale:* -This library explicitly requires the inheritance access level because derived classes must subcontract only from public bases, but not from protected or private bases (see __Public_Function_Calls__). -Therefore, [macroref BOOST_CONTRACT_BASE_TYPES] inspects each inheritance access level (using preprocessor meta-programming) and removes non-public bases from the list of bases inspected for subcontracting (i.e., from `base_types`). -] -This library will generate a compile-time error if the first base is missing its inheritance access level, but this library will not be able to always generate an error if the access level is missing for bases after the first one. -It is the responsibility of the programmers to make sure that all bases passed to [macroref BOOST_CONTRACT_BASE_TYPES] explicitly specify their inheritance access level (inheritance access levels are instead optional in C++ because `private` is implicitly assumed for `class` types and `public` for `struct` types). -Remember: -[:Always explicitly specify the inheritance access level `public`, `protected`, or `private` for base classes of derived classes with contracts.] -] - -See __Access_Specifiers__ to avoid making the `base_types` member type `public`. -[footnote -In this documentation the `base_type` member type is often declared `public` for simplicity. -However, in production code it might not be acceptable to augment the public members of a class adding the `base_types` type (and that can be avoided using [classref boost::contract::access] as explained in __Access_Specifiers__). -] -See [macroref BOOST_CONTRACT_BASES_TYPEDEF] to use a name different from `base_types` (e.g., because `base_types` clashes with other names in user-defined classes). - -[endsect] - -[section Static Public Functions] - -Contracts for public functions are programmed using [funcref boost::contract::public_function]. -In this section, let's consider static public functions. -For example (see [@../../example/features/static_public.cpp =static_public.cpp=]): - -[import ../example/features/static_public.cpp] -[static_public] - -It is possible to specify preconditions, postconditions, and exception guarantees for static public functions (see __Preconditions__, __Postconditions__, and __Exception_Guarantees__). -However, when called from static public functions, [funcref boost::contract::public_function] cannot take the object `this` as a parameter (because there is no object `this` in static member functions) so the enclosing class type is is specified as an explicit template parameter (because the class type is necessary to check static class invariants, see __Class_Invariants__): -
