Wouter van Oortmerssen 8f56990f6c FlexBuffers: C++: scalar-only typed vectors were not aligned.
This means data written with older versions of this code has
potentially misaligned data, which we'll need to support.
This isn't a problem on most architectures, but could be on
older ARM chips. To support them properly may require swapping
out uses of `flatbuffers::ReadScalar` with a version that does a
memcpy internally.

sjoblom65 47026ea6ba Added the code to embed the binary schema to the source (--bfbs-gen-embed). (#5701)
* Added the code to embed the binary schema to the source.
This is pulled forward from a old PR #5162 that will be closed.

* Update idl_gen_cpp.cpp

Added a small comment to trigger a new build. The build was failing in a strange location and doesn't look like it has anything to do with the code.

* Moved the EscapeAndWrapBuffer to util.cpp and did some formating.

* One more camelCases removed and renamed some variables.

* wrapped_line_xxx should have been passed as a const reference in the first place.

* Moved the bfbs embed sample to it's own file.

* Missed moving the namespace back.

* Moved the embedded bfbs to test.cpp instead of using a sample.

* Missed adding the generation of embedded bfbs to the build.

* See if this makes the build happier.

* Fixed a in-compatable cpp output of the generated header.

* Did some changes to reflect the code review comments.
1. Update the EscapeAndWrapBuffer to BufferToHexText and fixed a variable name.
2. Moved the include of the embedded binary schema to all the other includes.

* Moved some code to inline the instead of using a local variable.

* Moved the BufferToHexText back to be a inline function in util.h

Paulo Pinheiro 3f677f2414 [Java][FlexBuffers] Deprecate typed vector strings due to design flaw (#5722)
* [Java][FlexBuffers] Deprecate typed vector strings due to design flaw

It will still be possible to read buffers with this type, but the
elements will be treated as FBT_KEY and will be read as null-terminated
string.

Trying to build a vector of strings as typed will throw an exception.

More information on https://github.com/google/flatbuffers/issues/5627

Also, fix another bug on strings, where long strings were not properly
aligned.

* [Java][FlexBuffers] Make FBT_VECTOR_STRING_DEPRECATED considered typed.

The logic for FlexBuffers.isVectorType() was changed
to not consider FBT_VECTOR_STRING_DEPRECATED a typed
vector, but that can lead to missinterpretation for
existing serialized data. So we are reverting.

Max Burke 6da1cf79d9 [rust] Add use declarations to Rust-generated bindings for imported FB definitions (#5645)
* Bugfix for Rust generation of union fields named with language keywords

Looking at ParseField, it appears that in the case of unions, an extra field with a `UnionTypeFieldSuffix` is added to the type definition, however, if the name of this field is a keyword in the target language, it isn't escaped.

For example, if generating code for rust for a union field named `type`, flatc will generate a (non-keyword escaped) field named `type_type` for this hidden union field, and one (keyword escaped) called `type_` for the actual union contents.

When the union accessors are generated, they refer to this `type_type` field, but they will escape it mistakenly, generating code like this:

```
  #[inline]
  #[allow(non_snake_case)]
  pub fn type__as_int(&self) -> Option<Int<'a>> {
    if self.type__type() == Type::Int {
      self.type_().map(|u| Int::init_from_table(u))
    } else {
      None
    }
  }
```

Which will fail to build because the field is called `self.type_type()`, not `self.type__type()`.

* [Rust] Add crate-relative use statements for FBS includes.

At present if a flatbuffer description includes a reference to a type in
another file, the generated Rust code needs to be hand-modified to add
the appropriate `use` statements.

This assumes that the dependencies are built into the same crate, which
I think is a reasonable assumption?

* Revert "[Rust] Add crate-relative use statements for FBS includes."

This reverts commit d554d79fec.

* Add updated generated test files.

* Fixing Rust test harness to handle new includes.

Test binaries need to add references to generated code that's
transitively included.

This also has the knock-on in that this code (which is referenced by
include directives directly in the flatbuffer schema files) also needs
to be generated, hence the changes to generate_code.sh.

* Test harnesses expect test data to be checked in.

Put include_test2 files into the same directory as the include_test2
schema definition.

Update all code generation scripts (forgot the batch file from last
time).

David P. Sicilia a5d9d0f7d3 [C++17] Add Traits class for Tables and Factory function within it. (#5678)
* Include flattests_cpp17 in unit tests when C++17 build is enabled.

* [C++17] Generate generic table factory function.

1. For each table, generate a convenient free-standing factory
   function that allows creating the table in a generic way by
   specifying only the type.  This is the first change in a series
   of changes to make Flatbuffers generated C++ code more friendly
   to code bases that make use of C++ template metaprogramming
   techniques to manage the serialization process.  Example:

     Before :(

       // The name of the Flatbuffers type (and namespace) must
       // be hard-coded when writing the factory function.
       auto monster = MyGame::Example::CreateMonster(fbb, ...);

     After  :)

       using type_to_create = MyGame::Example::Monster;
       // No namespace needed on CreateByTagType.
       auto monster = CreateByTagType((type_to_create*)nullptr,
                                      fbb, ...);

   This feature requires building with C++14 or greater, and thus
   it is guarded behind --cpp-std >= c++17 in the flatbuffers C++
   generator.

2. Fix a CMake bug to include C++17 unit tests in test suite.

* [C++17] Replace standalone variadic factory function with type_traits.

Add a `type_traits` to each table class.  This `type_traits` can be
populated with various compile-time info about the table.  Initially,
we have the Create* function and type, but is extensible in the future.

* Remove empty line and fix stale comments.

* Rename type_traits to Traits and move fwd declaration.

* Fix parameter evaluation order issue and use lambda for scope.
