py-cffi: updated to 1.11.3
v1.11.3
Fix on CPython 3.x: reading the attributes __loader__ or __spec__ from the \
cffi-generated lib modules gave a buggy SystemError. (These attributes are \
always None, and provided only to help compatibility with tools that expect them \
in all modules.)
More Windows fixes: workaround for MSVC not supporting large literal strings in \
C code (from ffi.embedding_init_code(large_string)); and an issue with \
Py_LIMITED_API linking with python35.dll/python36.dll instead of python3.dll.
Small documentation improvements.

Log message:
py-cffi: update to 1.11.0
v1.11
Support the modern standard types char16_t and char32_t. These work like \
wchar_t: they represent one unicode character, or when used as charN_t * or \
charN_t[] they represent a unicode string. The difference with wchar_t is that \
they have a known, fixed size. They should work at all places that used to work \
with wchar_t (please report an issue if I missed something). Note that with \
set_source(), you need to make sure that these types are actually defined by the \
C source you provide (if used in cdef()).
Support the C99 types float _Complex and double _Complex. Note that libffi \
doesn’t support them, which means that in the ABI mode you still cannot call C \
functions that take complex numbers directly as arguments or return type.
Fixed a rare race condition when creating multiple FFI instances from multiple \
threads. (Note that you aren’t meant to create many FFI instances: in inline \
mode, you should write ffi = cffi.FFI() at module level just after import cffi; \
and in out-of-line mode you don’t instantiate FFI explicitly at all.)
Windows: using callbacks can be messy because the CFFI internal error messages \
show up to stderr—but stderr goes nowhere in many applications. This makes it \
particularly hard to get started with the embedding mode. (Once you get started, \
you can at least use @ffi.def_extern(onerror=...) and send the error logs where \
it makes sense for your application, or record them in log files, and so on.) So \
what is new in CFFI is that now, on Windows CFFI will try to open a non-modal \
MessageBox (in addition to sending raw messages to stderr). The MessageBox is \
only visible if the process stays alive: typically, console applications that \
crash close immediately, but that is also the situation where stderr should be \
visible anyway.
Progress on support for callbacks in NetBSD.
Functions returning booleans would in some case still return 0 or 1 instead of \
False or True. Fixed.
ffi.gc() now takes an optional third parameter, which gives an estimate of the \
size (in bytes) of the object. So far, this is only used by PyPy, to make the \
next GC occur more quickly (issue 320). In the future, this might have an effect \
on CPython too (provided the CPython issue 31105 is addressed).
Add a note to the documentation: the ABI mode gives function objects that are \
slower to call than the API mode does. For some reason it is often thought to be \
faster. It is not!

Log message:
Updated py-cffi to 1.10.0.
v1.10
Issue #295: use calloc() directly instead of PyObject_Malloc()+memset()
to handle ffi.new() with a default allocator. Speeds up
ffi.new(large-array) where most of the time you never touch
most of the array.
Some OS/X build fixes (âonly with Xcode but without CLTâ).
Improve a couple of error messages: when getting mismatched
versions of cffi and its backend; and when calling functions
which cannot be called with libffi because an argument is a
struct that is âtoo complicatedâ (and not a struct pointer,
which always works).
Add support for some unusual compilers (non-msvc, non-gcc,
non-icc, non-clang)
Implemented the remaining cases for ffi.from_buffer. Now all
buffer/memoryview objects can be passed. The one remaining check
is against passing unicode strings in Python 2. (They support
the buffer interface, but that gives the raw bytes behind the
UTF16/UCS4 storage, which is most of the times not what you
expect. In Python 3 this has been fixed and the unicode strings
donât support the memoryview interface any more.)
The C type _Bool or bool now converts to a Python boolean when
reading, instead of the content of the byte as an integer. The
potential incompatibility here is what occurs if the byte
contains a value different from 0 and 1. Previously, it would
just return it; with this change, CFFI raises an exception in
this case. But this case means âundefined behaviorâ in C; if
you really have to interface with a library relying on this,
donât use bool in the CFFI side. Also, it is still valid to use
a byte string as initializer for a bool[], but now it must only
contain \x00 or \x01. As an aside, ffi.string() no longer works
on bool[] (but it never made much sense, as this function stops
at the first zero).
ffi.buffer is now the name of cffiâs buffer type, and ffi.buffer()
works like before but is the constructor of that type.
ffi.addressof(lib, "name") now works also in in-line mode, not
only in out-of-line mode. This is useful for taking the address
of global variables.
Issue #255: cdata objects of a primitive type (integers, floats,
char) are now compared and ordered by value. For example, <cdata
'int' 42> compares equal to 42 and <cdata 'char' b'A'> compares
equal to b'A'. Unlike C, <cdata 'int' -1> does not compare equal
to ffi.cast("unsigned int", -1): it compares smaller, because
-1 < 4294967295.
PyPy: ffi.new() and ffi.new_allocator()() did not record âmemory
pressureâ, causing the GC to run too infrequently if you call
ffi.new() very often and/or with large arrays. Fixed in PyPy
5.7.
Support in ffi.cdef() for numeric expressions with + or -.
Assumes that there is no overflow; it should be fixed first
before we add more general support for arbitrary arithmetic on
constants.

Log message:
Updated py-cffi to 1.9.1.
v1.9
Structs with variable-sized arrays as their last field: now we
track the length of the array after ffi.new() is called, just
like we always tracked the length of ffi.new("int[]", 42). This
lets us detect out-of-range accesses to array items. This also
lets us display a better repr(), and have the total size returned
by ffi.sizeof() and ffi.buffer(). Previously both functions
would return a result based on the size of the declared structure
type, with an assumed empty array. (Thanks andrew for starting
this refactoring.)
Add support in cdef()/set_source() for unspecified-length arrays
in typedefs: typedef int foo_t[...];. It was already supported
for global variables or structure fields.
I turned in v1.8 a warning from cffi/model.py into an error:
'enum xxx' has no values explicitly defined: refusing to guess
which integer type it is meant to be (unsigned/signed, int/long).
Now Iâm turning it back to a warning again; it seems that
guessing that the enum has size int is a 99%-safe bet. (But
not 100%, so it stays as a warning.)
Fix leaks in the code handling FILE * arguments. In CPython 3
there is a remaining issue that is hard to fix: if you pass a
Python file object to a FILE * argument, then os.dup() is used
and the new file descriptor is only closed when the GC reclaims
the Python file objectâand not at the earlier time when you
call close(), which only closes the original file descriptor.
If this is an issue, you should avoid this automatic convertion
of Python file objects: instead, explicitly manipulate file
descriptors and call fdopen() from C (...via cffi).
