CodePorting.Native Cs2Cpp 21.12

Major Features

1. The compilation issues with GCC 10.0 and Clang 13.0 were fixed across our headers and in the generated code.
2. The performance of the Stream and TextWriter methods was improved. The methods of these classes no longer copy the smart pointers that are passed to them. The API for these classes and their subclasses was changed accordingly.
3. The System::Collections::Generic::IEnumerable<T>::get_Current() method now returns const references to pointers and strings to avoid the copying where possible. This increases the performance. The porter avoids returning reference to the temporary variables by generating service code which assigns such temporary values to enumerator’s field. The CppDisableEnumeratorCurrentValueHolder and CppEmitEnumeratorCurrentValueHolder attributes and the emit_enumerator_current_value_holder option were introduced. They can be used to impose manual control over such behavior.
4. The packaging scheme for the Linux OS was changed. The single CodePorting.Native.Cs2Cpp_x86_64_libstdcpp_21.12.zip package is now provided instead of compiler-specific versions. The single libaspose_cpp_x86_64_libstdcpp_libc2.23.so library should now be used with any compiler on the Linux OS.

Minor fixes

1. The exceptions thrown by the Socket and Dns classes were improved.
2. The class_ptr_alias option was supported by the porter. For each public class, the porter generates Ptr member type which is an alias to the smart pointer for this class when this option is enabled.
3. The code of Array::CopyTo() and ArrayView::CopyTo() methods was simplified.
4. The overloads were added to RandomNumberGenerator and RNGCryptoServiceProvider methods that work with ArrayView and StackArray instead of ArrayPtr.
5. The access violation was fixed in the HttpWebResponse::GetResponseHeader() method.
6. The HMACSHA512 class was implemented.
7. The porter no longer generates unwanted ToString() calls when translating the additional test failure message.
8. The porter no longer generates unwanted forward declarations when translating the generic delegates.
9. More usage examples were added to the API reference.
10. The indentation was fixed in the generated code for the member initializers.
11. The conditions of generating the SetTemplateWeakPtr() method were fixed.
12. Unwanted Boost symbols are no longer exported from Linux builds.
13. The System::String to std::*string conversion operators were moved to the string.h header.
14. The memory management issue was fixed inside the System::String::Join() method.
15. The force_const_ref_return_type_simple_properties porter option was improved. When it is enabled, the porter generated incorrect code for the properties where the property type didn’t match the type of the field being returned. This was fixed. Also, this option now supports the properties with more than one return statement and with the field of the field (of the field, and so on) being returned. Previously, only a single return statement with this class’es fields were supported.
16. The bug was fixed in the porter. The overload methods with iostream-like arguments were ill-formed in case of non-void return types. This was fixed.

Full List of Issues Covering all Changes in this Release

Public API and Backward Incompatible Changes

1. The get_Current method of the IEnumerable class and its inheritors now returns the value by reference instead of returning by value when a collection stores reference types or strings. The implementations of this method should be updated where applicable.
2. Methods of Stream, TextWriter and their inheritor classes now accept arguments by const reference instead of copying pointers. The overriding methods should be updated where applicable.
3. The suffix of the library built for Linux OS was changed. Now the code built using any compiler should be linked against libaspose_cpp_x86_64_libstdcpp_libc2.23.so. libaspose_cpp_gcc6.so and libaspose_cpp_clang3_libstdcpp.so are no longer provided.
4. The supported glibc version may be changed in the upcoming releases.
5. The new implementation of the classes that belong to the System::Xml namespace will be provided in one of the upcoming releases. Minor API changes are to be expected.
6. The new IEnumerable-level iterators and iterators for collections with duck typing will be introduced in one of the upcoming releases. The code which is dependent on EnumeratorBasedIterator or DuckTypedIterator may require some changes.
7. The CODEPORTING_CURRENT_RETTYPE macro was deprecated. It will be removed in one of the upcoming releases.
