Added DRAW command dlocale to set and query current locale of the C subsystem
Equivalents of C functions working with conversions of strings to/from reals added in Standard_CString, providing locale-independent behavior (using always "C" locale)
In DRAW packages, calls to atof() and atoi() are replaced by direct calls to Draw::Atof() and Draw::Atoi(), respectively, instead of substituting by #define
Use of atof(), strtod(), and *scanf() involving floating point conversions in OCCT code replaced by locale-independent Atof() and Strtod()
Calls to sprintf() involving floating point in OCCT code are replaced by call to locale-independent Sprintf(), except a few places where converted strings are used immediately for display in the 3d viewer
Changes of global locale are eliminated throughout OCCT code
Proposed correction for GNU libC where v*printf_l functions are absent
Added test case (bugs xde bug22898) for data exchange operations with non-standard locale
Use xlocale on Mac OS X and within glibc
Corrected strtod_l wrapper
Generate error rather than warning
Introduce Standard_CLocaleSentry replacement for removed OSD_Localizer
Standard_CLocaleSentry - copy locale string
Standard_CLocaleSentry - use _configthreadlocale on Windows
Standard_CLocaleSentry::GetCLocale() - return locale_t rather than void*
Corrected misprint in ~Standard_CLocaleSentry()
Use French locale in bug22898 test case
Mark test case as skipped if locale is unavailable on tested system.
Use fr_FR locale for tests on Mac OS X
Commit details:
1) in OSD_PerfMeter, use static functions of OSD_Chronometer class for time measurements instead of specific code to avoid incorrect results on CentOS (due to wrong valus of CLK_TCK);
2) changed definition of OSD_PerfMeter from .c to .cxx to avoid problems with C-functions;
3) fixed OSD_PerfMeter.h for building on Unix systems;
4) removed platform-specific #defines;
5) added test case for OSD_PerfMeter as bugs fclasses bug23237;
6) Removed DebugTools package (duplicates OSD_PerfMeter)
7) Avoid compiler (GCC) error casting BRepPrimAPI_Make* instances to TopoDS_Shape
Added Graphic3d_GraphicDriver::MemoryInfo() function.
Added vfps command to estimate average frame rate of 3D Viewer
Simplified vdrawsphere command
Removed turnVbo and performance measurements from vdrawsphere.
Added vvbo command to control VBO usage flag.
Added vmemgpu command to display GPU memory info from graphic driver
