Some generic C++ and Rust code is not generated when unions use type
aliases because of potential ambiguity. Actually check for this
ambiguity and only disable offending code only if it is found.
This is because they are incompatible with C++ and possibly other
languages that make them minimum size 1 (to make sure multiple
such objects don't reside at the same address). Forcing them to size
1 was also not practical, as that is requires updating the logic
of a lot of implementations and thus possibly backwards incompatible.

Change-Id: I2bfdc8597b7cfd2235bb4074bb2ae06f81f8e57d
* Add '-fsanitize' optional flags to flattests and flatc targets
Control: -DFLATBUFFERS_CODE_SANITIZE=(ON | OFF | "=memory,undefined")
Travis-CI: building with -DFLATBUFFERS_CODE_SANITIZE=ON
* Fix -pie flag
* Cleanup
Give the vtable offset enum inside each table the name
"FlatBuffersVTableOffset" and base type voffset_t so it can be used as a
dependent type in IsFieldPresent. This makes that function slightly
safer since it prevents calling it with arbitrary, non-table types.
Now, the only way to use IsFieldPresent incorrectly is to create your
own type which does not inherit from flatbuffers::Table but has a
dependent voffset convertible type "FlatBuffersVTableOffset".
* call reflection code generation from tests
This simplifies instructions to contributors so they don't forget to update
reflection code.
* add error handling to generate_code scripts
Let them propagate their errors instead of swallowing them so they show
up when called in CI.
* apply editorconfig to shell scripts
* use ordered map in dart codegen
Using an unordered map in the codegen can lead to spurious diffs in the
generated dart code.
* add CI check for generate_code being run
* update reflection_generated.h
* disable diff-check for monster_test.bfbs
Work around #5008.
* forbid enum values that are out of range
Enum values that are out of range can lead to generated C++ code that does
not compile. Also forbid boolean enums.
* update enum and union documentation slightly
* Efficient conversion of FlatBufferBuilder to grpc::MessageBuilder
* Added a variety of tests to validate correctness of the MessageBuilder move operations.
Disable MessageBuilder half-n-half tests on MacOS.
* Fix failing Android build
* Generalized the MessageBuilder move constructor to accept a deallocator
* Refactoring of numbers parser
More accurate parse of float and double.
Hexadecimal floats.
Check "out-of-range" of uint64 fields.
Check correctness of default values and metadata.
* Remove locale-independent code strtod/strtof from PR #4948.
* small optimization
* Add is_(ascii) functions
* is_ascii cleanup
* Fix format conversation
* Refine number parser
* Make code compatible with Android build
* Remove unnecessary suppression of warning C4127
Make an out-of-bounds check for enum values before using them to index the
names array. For consistency with non-sparse enums an empty string is
returned.
Fixes#4821
armeabi support was removed from the Android NDK so we should no
longer build it. Since this fixes the Android build failures this
commit also re-enables Travis Android builds.
While re-enabling Android builds, some recent changes broke C++98
support so this fixes those issues as well which include:
- Conditionally compiling use of move constructors, operators and
std::move.
- Changing sample to use flatbuffers::unique_ptr rather than
std::unique_ptr.
Finally, added the special "default_ptr_type" value for the
"cpp_ptr_type" attribute. This expands to the value passed to
the "--cpp-ptr-type" argument of flatc.
As recommended by https://golang.org/pkg/cmd/go/internal/generate/:
To convey to humans and machine tools that code is generated,
generated source should have a line early in the file that
matches the following regular expression (in Go syntax):
^// Code generated .* DO NOT EDIT\.$
With the old-style code, the test fails with a borrow-checker error:
```
#[inline]
pub fn name(&'a self) -> &'a str {
self._tab.get::<flatbuffers::ForwardsUOffset<&str>>(Monster::VT_NAME, None).unwrap()
}
```
```
error[E0597]: `e` does not live long enough
--> tests/integration_test.rs:273:57
|
273 | let enemy_of_my_enemy = monster.enemy().map(|e| e.name());
| ^ - `e` dropped here while still borrowed
| |
| borrowed value does not live long enough
274 | assert_eq!(enemy_of_my_enemy, Some("Fred"));
275 | }
| - borrowed value needs to live until here
```
* Fixed MakeCamelCase behavior when supplied Upper_Camel_Case,
snake_case and UPPERCASE strings.
* Modified the rust integration test to reflect changes.
* Add FlatBufferBuilder move semantics tests to main
Do not eagerly delete/reset allocators in release and release_raw functions
Update android, vs2010 build files
New tests for various types of FlatBufferBuilders and move semantics
* Improve test failure output with function names
* Add operator== for c++ genated code
New "--gen-compare" option for flatc to generate compare operators. The operators are defined based on object based api types.
Inspired by issue #263.
* Improve compare operator for c++.
Thanks for the code review.
- Improve robustness against future schema extensions
- Code style
- Fix --rust generation in generate_code.sh
This is a port of FlatBuffers to Rust. It provides code generation and a
runtime library derived from the C++ implementation. It utilizes the
Rust type system to provide safe and fast traversal of FlatBuffers data.
There are 188 tests, including many fuzz tests of roundtrips for various
serialization scenarios. Initial benchmarks indicate that the canonical
example payload can be written in ~700ns, and traversed in ~100ns.
Rustaceans may be interested in the Follow, Push, and SafeSliceAccess
traits. These traits lift traversals, reads, writes, and slice accesses
into the type system, providing abstraction with no runtime penalty.
Public access to the backing buffer uses Span<T> instead of ArraySegment<T>.
Writing to the buffer now supports Span<T> in addition to T[].
To maintain backwards compatibility ENABLE_SPAN_T must be defined.
* Added preprocessor define for C++ if Template Aliases are supported by the compiler
* Revert "Revert "Performance Increase of Vector of Structures using .NET BlockCopy (#4830)""
This reverts commit 1f5eae5d6a.
* Put<T> method was inside #if UNSAFE_BYTEBUFFER which caused compilation failure when building in unsafe mode
* Revert "Added preprocessor define for C++ if Template Aliases are supported by the compiler"
This reverts commit a75af73521.
