- STEP low-level parser is converted to C++; required minimal version of flex is elevated to 2.5.37.
- Added possibility to import STEP from stream, see new method XSControl_Reader::ReadStream() (now implemented in STEP only).
- Parsers ported to win_flex_bison 2.5.23 (flex 2.6.4, bison 3.7.1)
- Added support of C++ flex and bison scanners in in CMake scripts
- Some code clean-up in StepFile and around (unused files and functions are eliminated)
- Option to read from stream is added in DRAW command testreadstep for testing ReadStream() function
- Added test bugs step bug27342
Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms.
The class Message_ProgressIndicator is only an interface to the user application.
It accumulates the progress provided by progress scopes.
The counter is protected by mutex for thread-safety.
The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress.
The scopes are nested to each other to reflect the nested nature of operations.
The new class Message_ProgressRange should be used to pass the progress to sub-scopes.
All OCCT algorithms involving progress indication have been updated to new API.
Improvements in Draw_ProgressIndicator:
- Separate console mode has been added in order to make possible to put the progress into std::cout instead
or in addition to the draw interpreter, instead of trigger option "-tclOutput".
- Treatment of Ctrl-Break signal has been added.
Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke.
Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
Operators << for Handle(Message_Messenger) are removed; their use is replaced by use of Message_Messenger::StreamBuffer
Message_Messenger has been replaced by Standard_OStream within Interface_InterfaceModel,IFSelect,IGES,STEP dump interfaces.
"endl" manipulator for Message_Messenger is renamed to "Message_EndLine".
The following entities from std namespace are now used
with std:: explicitly specified (from Standard_Stream.hxx):
std::istream,std::ostream,std::ofstream,std::ifstream,std::fstream,
std::filebuf,std::streambuf,std::streampos,std::ios,std::cout,std::cerr,
std::cin,std::endl,std::ends,std::flush,std::setw,std::setprecision,
std::hex,std::dec.
All occurrences of Standard_EXPORT attached to inline methods in OCCT code are eliminated.
Some unused classes and C++ files producing no code are deleted.
Automatic upgrade of OCCT code by command "occt_upgrade . -nocdl":
- WOK-generated header files from inc and sources from drv are moved to src
- CDL files removed
- All packages are converted to nocdlpack
