Standard_Failure now holds an optional stack trace dump.
Added function Standard::StackTrace() dumping backtrace to the string.
SegvHandler within OSD_signal now appends backtrace to the message
if OSD::SignalStackTraceLength() is set to non-zero value
or environment variable "CSF_DEBUG_MODE" is set for debugging.
Added auxiliary macros Standard_NOINLINE disallowing function inlining.
Command "dsetsignal" has been extended by -strackTraceLength argument
for defining stack trace length within signals redirected to C++ exceptions.
Added "ddebugtraces" command for debugging purposes (adding stack traces to all exceptions).
New overload for method OSD::SetSignal() is added accepting argument specifying how to set or unset handlers.
New enum OSD_SignalMode describes different modes of signal handlers setting used in extended version of OSD::SetSignal().
Method OSD::SignalMode() returns mode set by the last call to SetSignal().
Method OSD::IsFloatingSignalSet() is changed to return value based on actual floating point exception flags (rather than on variable set by previous call to SetSignal()).
Added new method OSD::SetThreadLocalSignal() intended to setup thread-specific handlers (e.g. _set_se_translator() on Windows) and FPE settings.
OSD_ThreadPool and Media_PlayerContext now use new method instead of OSD::SetSignal(), to avoid overriding global handlers.
dsetsignal syntax has been extended to support choice of signal handling mode.
DRAW command OCC30775 is added allowing to test signal handling in multithreaded process.
Fixed license statements within files BRepGProp_MeshProps.cxx, BRepGProp_MeshProps.hxx,
OSD_ThreadPool.cxx and OSD_ThreadPool.hxx.
Removed non-ASCII char from BRepMesh_ModelHealer.hxx.
OSD_Parallel::ToUseOcctThreads() - new flag allowing to use OCCT threads implementation even when compiled with TBB (for testing).
Added new command dparallel for managing default Thread Pool.
OSD_Parallel::For() now avoid creation of universal iterator in simplest case.
BOPTools_Parallel - eliminated redundant typedefs/explicit instantiations of templates.
Added functor using array of per-thread context instead of a map.
New class OSD_ThreadPool has been introduced to define a Thread Pool for multi-threading algorithm.
Thread Pool assigns a serial number for each thread allowing Multi-Threading algorithm to allocate thread-local storage variables as an array whose size is the same as the number of threads.
OSD_ThreadPool also redirects exceptions to a thread calling parallel execution and consistently initializes FPE exception handling.
New class Standard_Condition provides a platform-independent tool similar to Event in WinAPI.
A new auxiliary function Standard_Atomic_CompareAndSwap() has been introduced
for performing atomic compare and swap of integer number.
Standard_Atomic_Increment/Standard_Atomic_Decrement fallback implementation
using ASM code for x86 processors for GCC has been dropped;
instead, it is expected that GCC should be properly configured targeting modern x86 architectures.
OSD_Signal now declares fFltExceptions as thread_local variable accessible through OSD::ToCatchFloatingSignals() property.
Standard_THREADLOCAL macro (wrapping thread_local attribute) has been moved to public header Standard_Macro.hxx.
OSD_Parallel::ForEach() has been extended with new optional parameter theNbItems and uses OSD_ThreadPool::DefaultPool().
