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)
This commit contains the first step in providing mutable FlatBuffers,
non-const accessors and mutation functions for existing fields generated
from --gen-mutable.

(Java doesn't support unsigned types).
ubyte/ushort return as int
uint returns as long
(all with correct masking)
ulong still returns as long, as before.
Tested: on Linux & Windows.

FlatBuffer schema files can now optionally specify a hash attribute that
will allow someone writing json files to enter a string to be hashed
rather than a specific value. The hashing algorithm to use is specified
by the schema.
Currently the only algorithms are fnv1 and fnv1a. There are 32 bit and
64 variatns for each. Additionally, a hashing command line tool was
added so that you can see what a string will hash to without needing to
inspect the flatbuffer binary blob.

changes.

Since part of it is based on the filename, which may contain

This would cause double definition linker errors when included in
multiple compilation units.

Theoretically, an attacker could construct a FlatBuffer with the
sole purpose of making verification really expensive, essentially
DOS-ing a server that uses verification on FlatBuffers. This adds
a max table depth and max table amount at which point the
verifier declares the buffer malformed.

Previously, it would ignore the fact that the type comes from a
different namespace. Now they are pre-declared in their own namespace,
and referenced with a qualified name if necessary.

It was outputting the type instead of the field name, and didn't deal
with NULL fields. Added test case.
Also fixed token enums having the wrong value, resulting in
unreadable error messages.

New attribute:
- `id: n` (on a table field): manually set the field identifier to `n`.
If you use this attribute, you must use it on ALL fields of this table,
and the numbers must be a contiguous range from 0 onwards.
Additionally, since a union type effectively adds two fields, its
id must be that of the second field (the first field is the type
field and not explicitly declared in the schema).
For example, if the last field before the union field had id 6,
the union field should have id 8, and the unions type field will
implicitly be 7.
IDs allow the fields to be placed in any order in the schema.
When a new field is added to the schema is must use the next available ID.
