Major Features

Following major improvements and fixes are applied in this regular monthly release:

1. Tests translation approach is improved. Now, virtual function called from methods marked with TestFixtureSetUp, TestFixtureTearDown, SetUp and TearDown attributes are fully supported. Also, TestFixture objects are now created once before running tests from current fixture, and deleted afterwards. ‘cleanup_tests’ option is now ignored by porter
2. Named mutex implementation is added
3. Compilation of library code using Visual Studio 2015 is explicitly disabled
4. Possible static initialization fiasco is now detected by porter and reported as warning
5. PreserveWhitespace mode is enabled for XmlDocument class
6. New ‘obfuscate_cpp_headers’ option is supported. It allows generating headers with some type and name information removed for non-public fields
7. New ‘nunit_assert_class_aliases’ option is supported. It allows treating calls into methods of some ported classes same way calls into NUnit’s Assert class methods are treated
8. Graphics::FillRegion() method is implemented
9. Threading::Thread class’es behavior is improved to match .Net behavior better. Now the thread is detached after start, so dropping thread object reference doesn’t result in interthreading errors
10. Several System::Diagnostics::Process methods are implemented for Linux platform
11. A way to detect multiimage gifs is added
12. Simple string raw pointer operations are supported inside ‘fixed’ statement

Minor fixes

1. StringBuilder now calls proper version of ToString() method even if not marked with CppConstMethod attribute
2. NS deduction mechanism is fixed in System::Xml::Node::SetAttribute() method
3. Array::Sort() implementation is fixed for value types supporting CompareTo method
4. Types of enumerators of collections from System::Collections namespace being treated as value types is fixed
5. Porter crash when having ambiguity between two or more methods, one having ‘params’-typed argument block, is fixed
6. Dot in subject string expression now properly matched against ‘any symbol’ dot by Regex class
7. ‘aspose_cpp’ library suffixes for Visual Studio 2017 are switched from ‘vc150’ to ‘vc141’ which is more common
8. System::String::Contains behavior is fixed for empty string used as argument
9. XmlTextReader::get_AttributeCount() is fixed when situations when reader is currently pointed to attribute node
10. Porter behavior is fixed for situations when method parameter name matches such of one of the class’es parameters
11. Graphics::MeasureString() behavior is fixed for some corner cases
12. Buffer::BlockCopy() method is fixed to work with rvalues when compiled with GCC
13. GraphicsPath::AddBeziers() overloads are implemented
14. PlatformNotSupportedException exception type is supported
15. Environment::GetFolderPath() is supported on Linux for SpecialFolder::Personal folder type
16. Visualizations of System::String and System::SmartPtr inside Visual Studio are fixed and improved
17. Accuracy of Graphics::MeasureString() method is improved. Special treatment of leading spaces is added. Behavior when no glyphs are present in the font used is fixed
18. ‘exclude’ parameter of ‘cut_namespaces’ option is fixed to work with delegates
19. Some errors within FileStream class are fixed
20. Header name resolving mechanism is fixed when porter-generated header name matches name of existing header file
21. Few memory issues within the library are fixed
22. Complex assignment operators on indexers are fixed. There is an expression duplication issue causing increment or other similar operations to be executed twice
23. List and Array sorting order is fixed for NaN values to match C# behavior
24. GraphicsPath::AddPolygon() behavior is fixed for some cases.
25. Tiff format with CMYK color model is now supported
26. XmlConvert::ToString() method now uses correct invariant culture with DateTime objects.
27. Quality of hashes provided by Object::GetHashCode() method is improved.
28. False positive ‘Failed to parse constructor initializer’ porter errors are downgraded to warnings. The aren’t removed totally to avoid loosing true alerts.
29. String::Join() method is fixed for empty input array to return empty string instead of null string.
30. Missing include when using cascaded CppConstexpr attribute is fixed.

Full List of Issues Covering all Changes in this Release

Public API and Backward Incompatible Changes

1. The way tests were translated is changed. If you have tests in your solution, you must re-port full solution instead of individual project, as tests ported by previous porter versions won’t be compatible with tests ported by actual porter.
2. In System::Threading::Mutex class, Mutex(bool, String) constructor and Remove(String) static method are added.
3. System::Details::Skia namespace is moved to System::Drawing::Details::Skia. No clients’ code should be impacted.
4. IsMultiImage() method is added into Bitmap and Image classes.
