* Add flatc '--cpp_std' switch and sandbox for C++17 code generator
- Added 'flac --cpp_std legacy' for compatibility with old compilers (VS2010);
- Added experimental switch 'flac --cpp_std c++17' for future development;
- Added C++17 sandbox test_cpp17.cpp;
- C++ code generator generates enums with explicit underlying type to avoid problems with the forward and backward schema compatibility;
- Adjusted CMakeLists.txt, CI and generate code scripts to support of introduced '--cpp_std';
* Fix --cpp_std values: c++0x, c++11, c++17
* Add 'cpp::CppStandard' enum
* Add testing engine into test_cpp17
* Rebase to upstream/master
* Set default '--cpp-std C++0x'
* Fix code generation (--cpp_std C++11) in CMakeLists.txt
- Fix dependency declaration of grpctest target
* Revert --cpp-std for the tests from explicit C++11 to flatc default value (C++0x)
* Keep include prefix when converting from proto.
This change preserves the include prefix when generating flatbuffers
from proto (with FBS_GEN_INCLUDES) defined.
* Improve handling of imports in proto conversion.
Previously, there was no runtime flag to make proto->fbs conversion keep
the import structure of a collection of files. This change makes proto
conversion respect the --no-gen-includes flag and skip the output of
"generated" symbols.
* Make Rust constants public
Otherwise they cannot be accessed by code that consumes the generated
bindings.
* Re-generate test code
* Add a test for enum constants
Having a static_assert on MSAN and ASAN prevents
the fuzzers from being used with different engines,
like TSAN, UBSAN, … but also with fuzzers that aren't
using MSAN/ASAN like afl for example.
* Flatbuffers Python Object API
Implement the logic to generate the Python object API that can
unpack the data from a buf class into an object class, and pack
the data of an object class to a buf class.
* Fix the build issues
Remove unused parameters and replace auto in the for-loop statement
with std::string to make it compatible with VS2010.
* Fix the build issues.
* Add support for Array type
Added logic to handle Array type in Python Object API. Updated the
generated code accordingly.
* Fix the old style casting from int to char
* Fixed another conversion from int to char
* Fixed the import for typing
Importing typing may cause errors when a machine do not have the
moduel typing installed. This PR fixes the issue by guarding
"import typing" with the "try/except" statement.
* Fix issue of iterating the vector of import list
* Update the generated examples using generate_code.sh
* Fix the import order for typing
The import list was stored in unordered_set, so that each generated
codes may have different import order. Therefore, it failed in the
consistency test where two generated copies need to have exactly the
same apperance.
* Optimize unpack using numpy
Use numpy to unpack vector whenever it is possible to improve unpack
performance.
Also, added codegen command for Python specificly in generate_code.sh,
because --no-includes cannot be turn on for Python.
* Fix the import order
* Update generate_code.bat for windows accordingly
* Replace error message with pass
Avoid printing error message for every Python2 users about typing.
Replace it with pass.
* Add C++ build testing with clang and gcc
This adds Dockerfiles which test building flatc and the C++ library against clang
and gcc. See discussion at #5119. It is derived from the Travis CI tooling.
The GRPC tests are failing due to #5099 so those are commented out.
These are run from the .travis.yml file rather than the tests/docker/languages
folder because the builds may each take longer than 30 minutes and were hitting
Travis timeouts.
Parallel builds and build caching attempt to keep the build times low.
* Add GCC 8.3 and Clang 7.0 with sanitizers into CI (based on #5130)
- Add a docker based on Debian Buster.
- Add C++ building scripts for the docker.
- Leak-sanitizer requires SYS_PTRACE.
* Added basic schema evolution tests
* Add BUILD targets for evolution tests. Added to test/generate_code scripts
* Use vector.front() instead of vector.data()
* Added --scoped-enums option for evolution test
* Automatic refractor of C++ headers to Google C++ style guide
* Automatic refractor of C++ source to Google C++ style guide
* Automatic refractor of C++ tests to Google C++ style guide
* Fixed clang-format issues by running clang-format twice to correct itself. Kotlin was missing clang-format on after turning it off, so it was changed,
Kolin uses java library as dependency, which changed the way it access union vector recently
(e365c502ff).
This changes updates kotlin code generation to match Java's changes.
* Add forceDefaults opt to python Builder
* Add test functions for force_default option for python builder
* Simplify
* Add force default test for UOffsetTFlags
* Fix C/C++ Create<Type>Direct with sorted vectors
If a struct has a key the vector has to be sorted. To sort the vector
you can't use "const".
* Changes due to code review
* Improve code readability
Empty objects that inherit from Sized would try to access internal
ByteBuffer when Sized::size was called. So we add a single byte in
the empty buffer, so when size() is called it would return 0
The real position of a string is calculated by using the indirect() method,
which should be based on parentWidth and not byteWidth, as it was implemented.
We are also fixing the flag BUILDER_FLAG_SHARE_STRINGS on FlexBuffersBuilder
that was set as '1', same value as BUILDER_FLAG_SHARE_KEYS.
* Draft with Array specialization (#5508)
* Array specialization + SFINAE to fold copy-paste (#5508)
* Add implicit specialization of Array<scalar> and Array<struct> (#5508)
- Tag dispatching is used for implicit specialization
- Array<scalar> and Array<struct> have different iterators and accessors
- Array<scalar> and Array<struct> have different Mutate() methods
* Add implicit specialization of Array<scalar> and Array<struct> (#5508)
- Tag dispatching is used for implicit specialization
- Array<scalar> and Array<struct> have different iterators and accessors
- Array<scalar> and Array<struct> have different Mutate() methods
* Add element size parameter to __vector_as_arraysegment
Add element size parameter to __vector_as_arraysegment fixing issue where VectorAsBytes returns incorrect size span for multibyte element types.
* Update codegen
Update codegen and Table to return typed span.
* update test files
update test files
* [FlexBuffers][Java] Implementation of FlexBuffers API
This is the initial attemp to implement FlexBuffer on Java.
There is some limitations as compared to the C++ implementation:
1 - No mutations implemented yet
2 - Does not parse from json
Also, this initial implementation is not focused and performance, but
get the basics write. So there is many opportunities for optimization, for instance,
remove all enums, return CharSequence instead of Strings and object pooling.
* [FlexBuffers][Java] Optimizations and simplification of the Builder API.
This change removes BitWidth enum in favor of static ints. Also
make all "reads" APIs closer to C++ implementation (try to cast or convert
as much as possible, assuming user knows what he is doing). Finally,
we remove the helper classes for building vectors and maps.
There is no official benchmarks, but the unit tests are running in less
than 50% for previous runs, which mean those optimizations are worth it.
* [FlexBuffers][Java] Fix Reference::asString behavior
There was a incorrect assumption that strings would be null-terminated, which
could lead to truncated strings. S now it relies size instead of null-termination.
Other minor improvements
