63b7b25289 FlatBuffers 64 for C++ (#7935)
* First working hack of adding 64-bit. Don't judge :)

* Made vector_downward work on 64 bit types

* vector_downward uses size_t, added offset64 to reflection

* cleaned up adding offset64 in parser

* Add C++ testing skeleton for 64-bit

* working test for CreateVector64

* working >2 GiB buffers

* support for large strings

* simplified CreateString<> to just provide the offset type

* generalize CreateVector template

* update test_64.afb due to upstream format change

* Added Vector64 type, which is just an alias for vector ATM

* Switch to Offset64 for Vector64

* Update for reflection bfbs output change

* Starting to add support for vector64 type in C++

* made a generic CreateVector that can handle different offsets and vector types

* Support for 32-vector with 64-addressing

* Vector64 basic builder + tests working

* basic support for json vector64 support

* renamed fields in test_64bit.fbs to better reflect their use

* working C++ vector64 builder

* Apply --annotate-sparse-vector to 64-bit tests

* Enable Vector64 for --annotate-sparse-vectors

* Merged from upstream

* Add `near_string` field for testing 32-bit offsets alongside

* keep track of where the 32-bit and 64-bit regions are for flatbufferbuilder

* move template<> outside class body for GCC

* update run.sh to build and run tests

* basic assertion for adding 64-bit offset at the wrong time

* started to separate `FlatBufferBuilder` into two classes, 1 64-bit aware, the other not

* add test for nested flatbuffer vector64, fix bug in alignment of big vectors

* fixed CreateDirect method by iterating by Offset64 first

* internal refactoring of flatbufferbuilder

* block not supported languages in the parser from using 64-bit

* evolution tests for adding a vector64 field

* conformity tests for adding/removing offset64 attributes

* ensure test is for a big buffer

* add parser error tests for `offset64` and `vector64` attributes

* add missing static that GCC only complains about

* remove stdint-uintn.h header that gets automatically added

* move 64-bit CalculateOffset internal

* fixed return size of EndVector

* various fixes on windows

* add SizeT to vector_downward

* minimze range of size changes in vector and builder

* reworked how tracking if 64-offsets are added

* Add ReturnT to EndVector

* small cleanups

* remove need for second Array definition

* combine IndirectHelpers into one definition

* started support for vector of struct

* Support for 32/64-vectors of structs + Offset64

* small cleanups

* add verification for vector64

* add sized prefix for 64-bit buffers

* add fuzzer for 64-bit

* add example of adding many vectors using a wrapper table

* run the new -bfbs-gen-embed logic on the 64-bit tests

* remove run.sh and fix cmakelist issue

* fixed bazel rules

* fixed some PR comments

* add 64-bit tests to cmakelist

c992eafb5b [fuzzer] Add monster_debug target (#6513)

82836a62be [idl_parser] Improve stack overflow protection (#6364)
* [idl_parser] Improve stack overflow protection

Add stack overflow protection for Flexbuffer and nested Flatbuffer parsers.
Replaces the `Recurse()` method by the new ParseDepthGuard RAII class.

* Remove move operator from Parser.

It was wrong decision to add move ctor and assignment into Parser class.
These operators will make it extremely difficult to add constant or reference fields in the future.

* Remove ';' from definition of FLATBUFFERS_DELETE_FUNC

* Format code

* Make this PR compatible with MSVC2010 (it doesn't support inherited ctor)

92a806b4e8 [fuzzer] Rename fuzzing dictionaries for oss-fuzz (#6318)
This commit makes the names of fuzzing dictionaries the same as the target binary names.
Also it explicitly limits size of test inputs to prevent failures in `regex` and fuzzing time-outs.

9b034eee12 Fix interpretation of 'nan(number)' by the idl_parser (#5810)
* Parser reject "nan(n)" string as it does with nan(n)

* Adjust scalar fuzzer to ignore '$schema' substrings

- Scalar fuzzer ignores '$schema' substrings at the input
- Added 'scalar_debug' target to simplify research of fuzzed cases

* Improve formatting of './tests/fuzzer/CMakeLists.txt'
