read_string() looped on stream_.peek() to scan a STEP string/binary
literal, assuming peek() returns 0 at EOF. It actually throws
std::out_of_range("peek at EOF"). A fuzzed file with a missing or
relocated closing quote leaves the decoder with no terminator before
it, so the loop runs the cursor past the end of the buffer and the
exception comes up uncaught, aborting the process.
Check stream_.eof() in the loop condition so an unterminated literal
ends the scan at EOF instead of throwing, and log a SYN warning for
the unterminated case (tracked via a "closed" flag so this doesn't
fire for the pre-existing null-byte early exit).
Fixes builds with newer GCC/libstdc++ that no longer provide <cstdint>,
<cstring>, <cfloat>, <memory>, <algorithm> etc. transitively. Also
disambiguates visit<> calls in taxonomy.h with the full namespace and
casts the character value in IfcCharacterDecoder to uint32_t to silence
ambiguous overload warnings.
* Preliminary MSYS2 + MinGW build scripts and instructions.
* CMakeLists.txt: MinGW tweaks, enforce C++03, suppress warnings for now.
* Fix some GCC warnings.
* Fix unused parameter warnings coming from Ifc*.h.
* Fix warning regarding unreachable code (++jt) on MSVC.
* Add IfcParse_EXPORT for IfcInvalidTokenException
* Fix potentially uninitialized pointer variables.
* Note about OpenCASCADE cyclic dependencies fix.
* GCC warning fix: don't generate 'current_enum' variable that is only set and not used for anything ever
* Work around -Wmaybe-uninitialized warnings about boost::optional constructs. Also prevent passing of negative values for --bounds.
* Remove unused variable.
* CMakeLists.txt: ENABLE_BUILD_OPTIMIZATIONS for GCC (simply enforce -03)
* CMake: moved setting link directories before all the projects.
* Added IfcParse_Export header for declaring export macro.
* Added IFCPARSE_STATIC_DEFINE macro to all projects.
* Added include for export macro to swig file.
* Added IfcParse_EXPORT macro for all classes in headers generated by express parser.
* Allow removing boost.regex dependency by defining macro IFCPARSE_NO_REGEX.
* Fixed bug in deletion of ICU converter.
* Added export macro to most of the classes across headers
* Fixed memory leak: delete nested IfcAbstractEntity in EntityArgument.
* Fixed memory leak in destructor of IfcWritableEntity (args values).
====================================================================
- Use boost::optional for optional IFC arguments
- Use boost::uuid for the creation of GlobalIds
- New IfcGeomObjects setting to force alignment of TopoDS_Face normal to CCW orientation
- Removed static Ifc class, renamed to non-static IfcFile. IfcFile renamed to IfcSpfStream
- Introduced Logger class
- Introduced EntityBuffer class that keeps track of all writable entities created to add them all in once to the IfcFile class
