0030551: Foundation Classes - Integer overflow in NCollection_CellFilter HashCode
Signed integers are not used in hash code functions now to prevent undefined behavior on left shift operations with signed integers.
A possibility of negative values of hash codes is eliminated.
INT_MAX → IntegerLast() in hash code functions.
All found hash code functions behaves uniformly now: they return a value in the range [1, theUpperBound]. Relevant comments are added to such functions.
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.
New macro OCCT_NO_RVALUE_REFERENCE is introduced to disable methods using move semantics on obsolete compilers that do not support rvalue references.
TCollection_AsciiString, TCollection_ExtendedString, NCollection_UtfString - added method Swap(), move constructor, and move assignment operator.
Draw command QATestArrayMove is added to test for memory corruption if NCollection_Array1<> bound to local C buffer is returned from function by value.
TCollection_ExtendedString/TCollection_AsciiString description
has been updated to reflect usage of this classes for Unicode strings.
TCollection_ExtendedString now defines constructor taking wchar_t* (all platforms)
and method ::ToWideString() returning wchar_t* (Windows only).
TCollection_AsciiString now defines constructor taking wchar_t*.
TCollection_ExtendedString/TCollection_AsciiString now defines
auxiliary methods ::StartsWith() and ::EndsWith().
TCollection_ExtendedString internals has been updated to eliminate
duplicated code for converting between UTF-16 and UTF-8.
Code has been cleaned up from redundant explicit conversions to wchar_t*.
Global method OSD_OpenStream()/OSD_OpenFileBuf() have been replaced
by C++ template to eliminate copy-paste for different STL collections.
OSD_SharedLibrary now uses wide-char system API call LoadLibraryExW()
on Windows for consistency.
New macro Standard_UNUSED has been added for marking possibly unused functions and variables
(to suppress gcc/clang compiler warnings).
New method V3d_View::DiagnosticInformation() has been introduced
providing the access to low-level OpenGL context information
for diagnostic automated reports or displaying in application About System.
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
