* Enable --gen-onefile in Python
Made it possible to generate all python code in one file. Modified
py_test.py so that it can switch between the multi-file code and
the one-file code.
Updated PythonTest.sh and py_test.py so that the multi-file code
and the one-file code can be tested based on the same test code.
* Sync with google/flatbuffers
* Add --gen-onefile to generate_code.py
* Remove a lot of redundancy from the Python generated code.
Update tutorial to reflect new Python generated code.
* Add aliases for newly deprecated Python generated methods.
This should help with backwards compatibility.
* Fix incorrect names in deprecated comments.
* Add vectorNumElements attribute to Builder for simpler vector creation.
This adds a default to EndVector which should simplify its use.
* Update tutorial to reflect new default arg in Python EndVector.
* Remove optional argument to Python EndVector.
* Add generated files.
* Unset Builder.vectorNumElems when not in use.
* 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.

Mostly to make CI run again
* More formatting fixes

* ran generate_code.sh
* Extend the test of MonsterExtra
- Extend C++ test of MonsterExtra
- Add conversion of fbs/json NaNs to unsigned quiet-NaN
- Update documentation (cross-platform interoperability)
* Fix declaration of infinity constants int the test
* Use a hash table to index existing vtables
This allows for quick deduplication even in situations where there
might be thousands of vtables due to 'combinatoric explosion'.
This fixes issue #5301.
* Refactor 0-offset trimming
* Improve deduplication benchmark
The routine now generates a set of realistic logical layouts and
uses a timer function that randomly picks a layout for each iteration.
The benchmark runs in batches of # of logical layouts = 1, 10, 100, 1000.
(Note that due to alignment, the actual number of vtables is usually slightly
higher.)

* Fix issue #4389, bytes is returned when field is omitted
* Fix issue #4389, added generated python code after generator modification
This is something the format supports, but none of the builders
were doing. Can save 10-20% on FlatBuffer binary size!
Also fixed the Go tests.

Tested: on Linux.
When passing a unicode string to builder.CreateString, the
default encoding assumed all characters can be encoded
using ascii. Added a fix so a user can specify the
encoding and how to handle errors when creating strings.
+ Add state to the Builder object to track if we are inside a table,
and if we are finished building the buffer.
+ Use this data to check that a buffer is being built correctly.
+ Raise an exception if a buffer is not being built correctly.
+ Test that the exceptions happen as expected.
Based on d236dea.
Implement code generation and self-contained runtime library for Python.
The test suite verifies:
- Correctness of generated Python code by comparing output to that of
the other language ports.
- The exact bytes in the Builder buffer during many scenarios.
- Vtable deduplication correctness.
- Edge cases for table construction, via a fuzzer derived from the Go
implementation.
- All code is simultaneously valid in Python 2.6, 2.7, and 3.4.
The test suite includes benchmarks for:
- Building 'gold' data.
- Parsing 'gold' data.
- Deduplicating vtables.
All tests pass on this author's system for the following Python
implementations:
- CPython 2.6.7
- CPython 2.7.8
- CPython 3.4.2
- PyPy 2.5.0 (CPython 2.7.8 compatible)
