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.

* Blank lines
* Reverted changes related to top-level list parsing
* Styling: newline before else
* Taking out ProcessTableFields which is no longer needed as the top level list change was reverted.
* [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.
* 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).

* 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
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.
Use full paths as keys in the map of included files. Store logical
include path as a value, in order to put it to the generated file.
* Fix tests by accepting null |include_filename|.
* Fix self-includes code generators.
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.

* 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.

* 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.
This is because it trips up the Closure compiler with errors like:
ERROR - assignment to property bb of SomeTable

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.

Allow tables to be mapped to native types directly. For example, a table
representing a vector3 (eg. table Vec3 { x:float; y:float; z:float; }) can
be mapped to a "mathfu::vec3" native type in NativeTables. This requires
users to provide Pack and UnPack functions that convert between the
Table and native types. This is done by adding the "native_type" attribute
to the table definition.
To support user-defined flatbuffers::Pack and flatbuffers::UnPack functions,
support a "native_include" markup that will generate a corresponding
Also add an UnPackTo function which allows users to pass in a pointer to
a NativeTable object into which to UnPack the Table. The existing UnPack
function is now simply:
NativeTable* UnPack() {
NativeTable* obj = new NativeTable();
Table::UnPackTo(obj);
return obj;
}
Finally, allow native types to be given a default value as well which are
set in the NativeTable constructor. This is done by providing a
"native_default" attribute to the member of a table.

The conditions to add the "NONE" or "ANY" value in the enum were useless
because the user cannot provide a zero value or a bitmask (for "ANY") in
the bit_flags enum type.
Helps simplify code generation code. Instead of this:
code += "inline const " + cpp_qualified_name + " *Get";
code += name;
code += "(const void *buf) {\n return flatbuffers::GetRoot<";
code += cpp_qualified_name + ">(buf);\n}\n\n";
You do this:
code.SetValue("NAME", struct_def.name);
code.SetValue("CPP_NAME", cpp_qualified_name);
code += "inline const {{CPP_NAME}} *Get{{NAME}}(const void *buf) {";
code += " return flatbuffers::GetRoot<{{CPP_NAME}}>(buf);";
code += "}";
code += "";
Updated the CPP code generator to use the CodeWriter class. Most of the
changes in the generated code are white-space changes, esp. around new
lines (since the code generator class automatically appends new lines
when appending a string). Actual code changes include:
* Renamed "rehasher" to "_rehasher" for consistency with other args in
Pack function.
* Renamed "union_obj" to "obj: in UnPack function.
* Always do "(void)_o;" to prevent unused variable warning in Create
function (instead of only doing it if there are no fields) in order
to avoid two-passes.
* Renamed padding variables from __paddingX to paddingX__.
"Each name that contains a double underscore (_ _) [...] is reserved
to the implementation for any use." C++ standards 17.4.3.1.2.
* Add braces around switch cases.
* Calculate index as a separate statement in EnumName function, eg.
const size_t index = ...;
return EnumNamesX()[index];
vs.
return EnumNamesX()[...];
* Stored end table offset in variable in Finish() functions, eg.
const auto end = fbb_.EndTable(start_, ...);
auto o = flatbuffers::Offset<T>(end);
vs.
auto o = flatbuffers::Offset<T>(fbb_.EndTable(start, ...));
* Separate reinterpret_cast calls from function calls in Union
functions, eg.
auto ptr = reinterpret_cast<const T *>(obj);
return ptr->UnPack(resolver);
vs.
return reinterpret_cast<const T *>(obj)->UnPack(resolver);
* Removed unecessary (void)(padding__X) no-ops from constructors, eg.
Test(int16_t a, int8_t b) : ... {
(void)__padding0; // <-- Removed this line.

This commit fixes the BufferRef call site by adding a nullptr argument.
Unions own the NativeTable* value member because they need to destroy them
when the Union goes out of scope. Currently, the data is destroyed by calling
delete, which means that the member needs to be allocated with new. However,
making the allocation the responsibility of the client and the destruction
the responsibility of the Union can lead to potential errors. Adding a
Set function will ensure that the memory is allocated correctly so that it
can be deleted later.

Similar to what protobufs does with its `Message` interface, introduce here such interface and create a generic `GetRootAs` method to deserialize a flatbuffer.
They were overloaded, but also had default arguments, so would
become ambiguous when used with few arguments.

This avoid to put the pom.xml file into the source directory. Normally the pom file is in a parent (/parent) folder and it is not mixed with the java source code.
An other thing is: this will make import of the project more easy from a IDE.
The side effect is that the target folder where maven build artifacts will move from the <flatbuffers>/java/target to <flatbuffers>/target therefore the gitignore file has been updated in consequences.
This is useful because many JSON generators will sort the fields,
cause X_type to follow X.

Java developer are mostly comfortable with maven project structure. One one the main concept behind maven is convention. If you follow the maven project convention then your development team will get more effective as they now this project structure and can easily find the production code versus the test code.
In this pull request I have structured the java project around 2 main parts:
* the `flatbuffers` project. This project is the api / lib project and contains the test code structure + an example of code generation for testing. This avoid to commit generated code. Pre-configure JUnit for test driven development and make this project OSGi compliant.
* the `jmh` project. This project aims to provide a placeholder for micro-benchmarking. JMH is a 'de facto' standard for micro benchmarking you can find more details here: http://openjdk.java.net/projects/code-tools/jmh/
For now I didn't move the JavaTest class but it could be a next step with a migration to the JUnit framework.
The only impacts are the move of the class and the project structure => no code change.

GetObject and GetMutableObject are similar to GetRoot and GetMutableRoot,
and can be useful when wanting to access data that has just been created.
Unfortunately there is a danger in using these methods, as it is possible
that the buffer reallocates which will invalidate the pointers.
This avoids the following allocations over repeated use:
- A ``CharsetEncoder``
- A byte array to contain the contents of the string
- A wrapper, via ``ByteBuffer#wrap``, for the previously mentioned byte
array
This also removes a copy of the temporary byte array. This extra copy
is needed because ``String#getBytes`` returns a byte array and its
length must match the exact size of the contents.
This implementation requires that the builder retain a ``ByteBuffer``
and ``CharEncoder``. This is considered slower only for users that
will only allocate a single string in their buffers or none at all.
The improvement is especially potent if the builder is constantly reused
by its caller. This also eliminates the penalty for users that do not
use strings at all since the cost of allocating these fields is
now amortized.
The only allocation left in this code is a ``CharBuffer`` wrapper. It's
possible to eliminate this allocation using an additional copy but need
further profiling to see which is the bigger problem.
Removes the following allocations:
- ``CharsetDecoder`` is reused between calls
- ``CharBuffer#wrap`` removed in favor of heap
based char buffer that is reused
- Temporary ``char[]``, an intermediate copy inside ``StringCoding``
- Another ``char[]``, this is needed because ``StringCoding`` uses
a ``CharBuffer`` internally but returns a ``char[]``. Extra
characters need to be trimmed so this means yet another allocation
- Yet another ``char[]`` directly from ``__string`` for non-heap
based buffers
Removes the following copies
- No copy is performed to trim the allocation since a ``CharBuffer``
is used directly
- For non-heap based byte buffers, removes the copy that was
previously done in the __string function
This does need to get the TLS entry which implies at least some
contention on the thread object table and a fence.

CreateUninitializedVector was performing the following actions:
1. call StartVector.
2. call make_space, and set buf to point to the reserved space.
3. call EndVector.
The problem is that a call to EndVector can ultimately call make_space, which
if the buffer is full, will cause a reallocation, invalidating the value stored
in buf. So setting buf needs to be delayed until after EndVector.
The following code, when run under valgrind shows a write to free'd memory before
the change, but no such error after:
int main()
{
flatbuffers::FlatBufferBuilder fbb(128);
char *buf = nullptr;
fbb.CreateUninitializedVector(128, &buf);
*buf = 0;
}
This overflow could allow malformed FlatBuffers to pass the verifier.

To support the use case described in issue google/flatbuffers#3826, a new command line option --gen-name-strings
has been added, which will cause a static GetFullyQualifiedName function to be added
to the C++ output for tables/structs.
Currently in order to get a value type of [ubyte] in PHP, iteration is
necessary which is not efficient. Helper __vector_as_bytes has been
implemented in order to return the byte arrays in PHP efficiently.
Appropriate methods also been added to use aforementioned method to return
the byte array. (e.g. get*Bytes()).
The reason the methods are named get*Bytes() and not for instance
get*ByteArray() is the fact that PHP doesn't support byte arrays and the
binary safe string implementation in PHP is used to simulate byte arrays
and since there is chance for PHP users to confuse this with PHP arrays
the name get*Bytes() has been chosen.
In the future __vector_as_bytebuffer() method can also be implemented to
return PHP implementation of ByteBuffer.
Certain architectures, such as ARM, use unsigned chars by default
so require the `-fsigned-char` for certain value comparisons to
make sense and in order to compile.
This is the first step in RPC support. Actual code generation
to follow.

Bug: 20122696
There was no way to pass an already-encoded string to
`builder.CreateString` in Python 2.7:
- Passing a `bytearray` raised a TypeError because `bytearray` was not
recognized as an instance of `compat.binary_type`.
- Passing a utf-8 encoded `str` would cause the string to be
double-encoded, because `compat.string_types = (basestring,)` and
`basestring` is the base class of `str` and `unicode`, so the logic
would never reach the `elif isinstance(s, compat.binary_type)` case.
- Converting a utf-8 encoded bytearray to `bytes` like
`builder.CreateString(bytes(encoded_string))` does not work because
in Python 2.7, bytes is just an alias for `str` so it behaves as
above.
This change allows either `bytes` or `bytearray` as an already-encoded
string to be passed to `CreateString` in versions of Python that support
`bytearray`, and falls back to `str` in older versions.
In Python 2, it restricts unencoded string types to `unicode`, so `str`
can be used as an encoded, binary representaiton.
The code generator was assuming all declarations for the current
file sit in the same namepace. Now uses the "on demand" namespace
switching we had for the forward declarations.
Also fixed a bug related to namespace lookup.

Fix for Issue 1741
Minor bug where python versions 2.7.x where x < 5 do not support
unpacking from memoryview objects. Versions 2.7.5 and above will
use memoryview while 2.7 versions below 2.7.5 will use buffer
objects.
Manual testing was performed on versions 2.7.5 and 2.7.2 to
confirm both worked correctly.
It's slightly faster to convert the value to signed value in PHP as
opposed to use pack and unpack.
For 1M get operation the difference is:
getShort in 3.3272678852081 seconds
getInt in 3.8338589668274 seconds
getLong in 5.6381590366364 seconds
getLong (neg) in 5.6149101257324 seconds
vs
getShort in 2.7564418315887 seconds
getInt in 3.1612701416016 seconds
getLong in 3.1369340419769 seconds
getLong (neg) in 3.1478710174561 seconds
And since pack("P") and unpack("q") has been removed now ByteBuffer
works for PHP >= 5.4
I updated idl_gen_general.cpp to add support for generating a Get Bytes
method for a vector to the generated C# source code. Given a byte vector
field named Foo, a method named GetFooBytes() will be generated in the
C# source code that will return an ArraySegment<byte> value referencing
the vector data in the underlying ByteBuffer.
I added a method to Table.cs named __vector_as_arraysegment that is used
by the code generated by the change to the C# generator.
__vector_as_arraysegment will take the offset of the vector and will
return the ArraySegment<byte> value corresponding to the bytes that
store the vector data.
I updated FlatBuffersExampleTests.cs to add tests to validate my
implementation of Table.__vector_as_arraysegment. I added tests to
demonstrate that the bytes for the monster's name can be extracted from
the underlying byte array. I also added tests to show that
Table.__vector_as_arraysegment returns a null value if the vector is not
present in the FlatBuffer.
I used the updated flatc.exe program to regenerate the C# source files
for the MyGame example. The new Monster class includes the GetXXXBytes
methods to return the byte arrays containing data for vectors.

This adds an optional argument to generated getters for string fields to
specify the encoding type and overloads the createString() function. It's
now possible to use either JavaScript UTF-16 string objects or C-style
UTF-8 byte arrays (Uint8Array) for string data.
JavaScript uses UTF-16 but FlatBuffers uses UTF-8. This commit tests the code
that does the conversion between the two encodings. The last entry in the array
is tricky because each code point actually requires two UTF-16 code units,
unlike the other examples. The current JSON output of flatc actually handles
this case incorrectly (it generates invalid JSON with UTF-8 code units). The
generated JavaScript code passes these tests fine, however.
This adds a JavaScript language target. The generated JavaScript uses Google
Closure Compiler type annotations and can be compiled using the advanced
compilation mode, which performs type checking and optimizations such as
inlining and dead code elimination. The generated JavaScript also exports all
generated symbols for use with Node.js and RequireJS. This export behavior
can be turned off with the --no-js-exports flag for use with Google Closure
Compiler.
The pop_back function was added to strings in C++11 and it appears not
all compilers we target support it. The call to pop_back has been

This allows you to use these functions with a flatbuffer whose root
table type does't correspond with the root table type of the schema.
If you don't specify the table name, it will use the root table from
the schema by default (mimicing the current behavior).
This pull request should fix#232.
Pass field name instead of struct name as nameprefix for nested structures. Continuously concatenate nameprefix arguments to support deeper nested structures.
Before this change, requesting a large initial allocation could cause the
backing store to grow to an unaligned size. Since memory inside vector_downward
is relative to the end of the buffer, this then caused all memory in the buffer
to be misaligned and also misaligns any further loads and stores. Misaligned
loads and stores are undefined behavior and don't work in environments such as
emscripten (a JavaScript to C++ compiler).
On Android builds, set FLATBUFFERS_FLATC_ARGS to change the arguments
passed to the flatc cmdline. Do this in your Android makefile where
you include the flatbuffers include.mk (before or after).
