90c8ded449 gRPC: fix memory leak (#4351)
SerializationTraits<T>::Deserialize _transfers_ ownership of the buffer,
so we must destroy it.

This commit also includes some misc fixes:
- Use grpc::Status::OK rather than default ctor for clarity.
- Check for a null buffer passed into Deserialize, and handle it the
  same way as the protobuf deserializer.

86b505e412 [C++] Remove std::iterator usage (#4340) (#4341)
* [C++] Remove std::iterator usage (#4340)

Inheriting from std::iterator has never been required, and it's
deprecated in C++17. It can be replaced by directly providing typedefs.

Include <iterator> for std::random_access_iterator_tag.

Note that structs default to public access control.

* [C++] Change whitespace style in typedefs.

da67c0a71f [C++] Improve flatbuffers + gRPC integration (#4310)
* Rework flatbuffers + gRPC integration

- Introduce `flatbuffers::grpc::Message<T>`, a `grpc_slice`-backed
message buffer that handles refcounting and allows flatbuffers to
transfer ownership to gRPC efficiently. This replaces
`flatbuffers::BufferRef<T>`, which required a copy call and was also
unsafe w.r.t. buffer lifetime.
- Introduce `flatbuffers::grpc::MessageBuilder`, a gRPC-specific builder
that forces a `grpc_slice`-backed allocator and also adds some helpful
`Message<T>`-related methods.
- Update serializers accordingly (now zero-copy between flatbuffers and
gRPC).

* gRPC: verify messages by default, but allow user to override

* gRPC: fix some formatting issues

* Disable verification by default, but add helper method

* Make FlatBufferBuilder fields protected + remove vec accessor

* Use bool add_ref parameter to toggle refcount incr

* Remove unnecessary inline specifiers

01c50d57a6 [C++] Remove std::move around a raw pointer in flatbuffers.h (#4339)
* Remove std::move around a raw pointer

Calling std::move on a raw pointer has no advantage to just copying its value. Moreover, it is confusing, because it indicates that the argument is movable in some non-trivial way (e.g., is it actually meant to be a smart pointer?). More context in https://crbug.com/729393.

* Remove the move constructor altogether

43611fcc0b refactor flatbuffers.h and util.h so FlexBuffers do not depend on flatbuffers.h (#4331)
FlexBuffers are actually completely unrelated to FlatBuffers and can be used separately.
However, since they utilize several utility functions from flatbuffer.h, they require this header file, which creates unreasonable dependency.
By moving those utility functions to separate base header, both libraries can use same code but still be independent

* Track included files in PATH-agnostic way.

include path as a value, in order to put it to the generated file.

* Fix tests by accepting null |include_filename|.

22743ca45a Fixed --keep-prefix functionality.
Changing to keep include prefixes had two side effects: the main
file being parsed wasn't filtered out anymore, and include directory
paths would be added to the path in the include statement.

Also moved the include_test*.fbs files to sub directories so we
can actually test the handling of -I etc.

tested: on Linux.

fb87c0d3c6 [C++] Improve Allocator handling (#4312)
* Improve Allocator handling

- Templatize Allocator on vector_downward, and make it own the allocator
instance so it can manage lifetimes.
- Templatize + rename FlatBufferBuilderT accordingly, and add a typedef
to FlatBufferBuilder so old code continues to work.
- Fix some issues with the release deleter
- More details in github issue #4311

* Fix constexpr for older MSVC

* Reimplement allocator improvements via inheritance

Instead of templates, use an abstract base class and some unique_ptrs to
implement the new and improved allocator.

* Fix misplaced newline

* Add missing override keyword

* Add macro for func delete to support older compilers

* Explicitly move BufferDeleter (maybe fixes VS 10?)

* Revert previous attempt at VS10 fix

* Try yet another workaround for MS 10

* Use FLATBUFFERS_NOEXCEPT macro

* Add FLATBUFFERS_OVERRIDE macro

* Fix some issues with MSVC 16 hack

* Remove dep on unique_ptr

* Update DEPRECATED macro with a message

* Sigh, no delegating ctors before c++11

* Fix simple_allocator stub

* Relax FlatBufferBuilder ctor

* Add vector_downward reset + assert in clear

* Rename DetachedBuffer to FlatBuffer + remove unnecessary deprecations

* Add flatbuffers::FlatBufferBuilder::Release()

* Address remaining allocator-improvements comments

aaf5598a03 Standardized internal path handling on Posix separators.
There were several possible bugs involving paths not being
recognized as being the same on Windows. Rather than trying
to ensure all code deals with / and \ correctly, paths now
get transformed to / on input, fixing all current and
future such bugs.

Tested: on OS X.

c559eb451e Made codegen always output a file, even on an empty schema.
Previously, we had a check to simply skip such files, but this
tends to make build systems unhappy.

This only affects C++ and JS, since other language output per-class
files.

9aeeddf5ac C++/Go: Update gRPC related code to work with gRPC 1.3+ (#4305)
* Don't fail the build on unused parameters

gRPC headers have unused parameters so this breaks the test build.

* Pull in updated compiler files from gRPC

There have been some API breaks in gRPC lately. This commit
pulls in the most recent version of the files in this repo
that are just copied from gRPC.

* Modify the gRPC files so that they can work with Flatbuffers

The files taken from gRPC do not work out-of-the-box with Flatbuffers.
This commit modifies them so that they work. Hopefully this commit
will be able to serve as a guide or maybe even be cherry-picked on
top of new versions of those files as newer versions from gRPC are
pulled in.

* Adjust the rest of Flatbuffers to work with the new gRPC

* Change idl_gen_grpc.cpp to work with the new API
* Add missing #include in flatbuffers/grpc.h
* Run tests/generate_code.sh and check in the results
* Don't link with grpc++_unsecure and (secure) grpc. That's just weird

* Revert unrelated JS/TS test changes

* Simplify compiler/config.h

There is no need to import this file from gRPC. In fact, it probably
makes sense to not do so, since it seems to be intended to have
project specific configuration in it.

* Don't emit C++ types in the Go gRPC code generator

* Don't emit C++ #includes in generated gRPC code

Before this PR, there was a Go-specific additional_includes method
in schema_interface.h, which is shared with the gRPC repo. The
additional parameter to FlatBufFile in idl_gen_grpc.cpp makes that
unnecessary, which means we need less Flatbuffer-specific changes
in gRPC.

8b92122f33 Made the verifier catch zero-offsets.
Zero offsets are non-sensical in FlatBuffers (since offsets are
relative to themselves) but were allowed by the verifier. This could
cause buffers made up of all zeroes to be interpreted as correct
buffers with an empty root object.

Generally, not allowing such offsets will make the verifier more
likely to catch problems earlier.

* fix bounds checking on integer parsing

this patch fixes bounds checking for 8-bit, 16-bit and 32-bit types.
testing for both acceptable values and unacceptable values at the
boundaries are also improved.

bounds checking on 64-bit types isn't addressed by this patch.
