- update to 1.9.1
  - 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 I’m 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 object—and 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).
  - When passing a void * argument to a function with a different pointer type,
    or vice-versa, the cast occurs automatically, like in C. The same occurs
    for initialization with ffi.new() and a few other places. However, I
    thought that char * had the same property—but I was mistaken. In C you get
    the usual warning if you try to give a char * to a char ** argument, for
    example. Sorry about the confusion. This has been fixed in CFFI by giving
    for now a warning, too. It will turn into an error in a future version.
  - Issue #283: fixed ffi.new() on structures/unions with nested anonymous
    structures/unions, when there is at least one union in the mix. When
    initialized with a list or a dict, it should now behave more closely like
    the { } syntax does in GCC.
  - CPython 3.x: experimental: the generated C extension modules now use the
    “limited API”, which means that, as a compiled .so/.dll, it should work
    directly on any version of CPython >= 3.2. The name produced by distutils
    is still version-specific. To get the version-independent name, you can
    rename it manually to NAME.abi3.so, or use the very recent setuptools 26.
  - Added ffi.compile(debug=...), similar to python setup.py build --debug but
    defaulting to True if we are running a debugging version of Python itself.
  - Removed the restriction that ffi.from_buffer() cannot be used on byte
    strings. Now you can get a char * out of a byte string, which is valid as
    long as the string object is kept alive. (But don’t use it to modify the
    string object! If you need this, use bytearray or other official
    techniques.)
  - PyPy 5.4 can now pass a byte string directly to a char * argument (in older
    versions, a copy would be made). This used to be a CPython-only
    optimization.
  - ffi.gc(p, None) removes the destructor on an object previously created by
    another call to ffi.gc()
  - bool(ffi.cast("primitive type", x)) now returns False if the value is zero
    (including -0.0), and True otherwise. Previously this would only return
    False for cdata objects of a pointer type when the pointer is NULL.
  - bytearrays: ffi.from_buffer(bytearray-object) is now supported. (The reason
    it was not supported was that it was hard to do in PyPy, but it works since
    PyPy 5.3.) To call a C function with a char * argument from a buffer
    object—now including bytearrays—you write lib.foo(ffi.from_buffer(x)).
    Additionally, this is now supported: p[0:length] = bytearray-object. The
    problem with this was that a iterating over bytearrays gives numbers
    instead of characters. (Now it is implemented with just a memcpy, of
    course, not actually iterating over the characters.)
  - C++: compiling the generated C code with C++ was supposed to work, but
    failed if you make use the bool type (because that is rendered as the C
    _Bool type, which doesn’t exist in C++).
  - help(lib) and help(lib.myfunc) now give useful information, as well as
    dir(p) where p is a struct or pointer-to-struct.
- drop upstreamed python-cffi-avoid-bitshifting-negative-int.patch

-------------------------------------------------------------------
Tue Dec  6 14:39:52 UTC 2016 - jmatejek@suse.com

- update for multipython build

-------------------------------------------------------------------
Sun May 29 05:23:27 UTC 2016 - badshah400@gmail.com

- Add python-cffi-avoid-bitshifting-negative-int.patch to actually
  fix the "negative left shift" warning by replacing bitshifting
  in appropriate places by bitwise and comparison to self; patch
  taken from upstream git. Drop cffi-1.5.2-wnoerror.patch: no
  longer required.

-------------------------------------------------------------------
Fri May 27 13:00:22 UTC 2016 - jmatejek@suse.com

- disable "negative left shift" warning in test suite to prevent
  failures with gcc6, until upstream fixes the undefined code
  in question (boo#981848, cffi-1.5.2-wnoerror.patch)

-------------------------------------------------------------------
Thu May 26 02:33:02 UTC 2016 - badshah400@gmail.com

- Update to version 1.6.0:
  * ffi.list_types()
  * ffi.unpack()
  * extern “Python+C”
  * in API mode, lib.foo.__doc__ contains the C signature now.
  * Yet another attempt at robustness of ffi.def_extern() against
    CPython’s interpreter shutdown logic.

-------------------------------------------------------------------
Mon Apr 11 14:45:11 UTC 2016 - jmatejek@suse.com

- update to 1.5.2
  * support for cffi-based embedding
  * more robustness for shutdown logic

-------------------------------------------------------------------

- update to version 1.4.2:
  * Nothing changed from v1.4.1.
- changes from version 1.4.1:
  * Fix the compilation failure of cffi on CPython 3.5.0. (3.5.1
    works; some detail changed that makes some underscore-starting
    macros disappear from view of extension modules, and I worked
    around it, thinking it changed in all 3.5 versions—but no: it was
    only in 3.5.1.)
- changes from version 1.4.0:
  * A better way to do callbacks has been added (faster and more
    portable, and usually cleaner). It is a mechanism for the
    out-of-line API mode that replaces the dynamic creation of
    callback objects (i.e. C functions that invoke Python) with the
    static declaration in cdef() of which callbacks are needed. This
    is more C-like, in that you have to structure your code around the
    idea that you get a fixed number of function pointers, instead of
    creating them on-the-fly.
  * ffi.compile() now takes an optional verbose argument. When True,
    distutils prints the calls to the compiler.
  * ffi.compile() used to fail if given sources with a path that
    includes "..". Fixed.
  * ffi.init_once() added. See docs.
  * dir(lib) now works on libs returned by ffi.dlopen() too.
  * Cleaned up and modernized the content of the demo subdirectory in
    the sources (thanks matti!).
  * ffi.new_handle() is now guaranteed to return unique void * values,
    even if called twice on the same object. Previously, in that case,
    CPython would return two cdata objects with the same void *
    value. This change is useful to add and remove handles from a
    global dict (or set) without worrying about duplicates. It already
    used to work like that on PyPy. This change can break code that
    used to work on CPython by relying on the object to be kept alive
    by other means than keeping the result of ffi.new_handle()
    alive. (The corresponding warning in the docs of ffi.new_handle()
    has been here since v0.8!)
- changes from version 1.3.1:
  * The optional typedefs (bool, FILE and all Windows types) were not
    always available from out-of-line FFI objects.
  * Opaque enums are phased out from the cdefs: they now give a
    warning, instead of (possibly wrongly) being assumed equal to
    unsigned int. Please report if you get a reasonable use case for
    them.
  * Some parsing details, notably volatile is passed along like const
    and restrict. Also, older versions of pycparser mis-parse some
    pointer-to-pointer types like char * const *: the “const” ends up
    at the wrong place. Added a workaround.
- changes from version 1.3.0:
  * Added ffi.memmove().
  * Pull request #64: out-of-line API mode: we can now declare
    floating-point types with typedef float... foo_t;. This only works
    if foo_t is a float or a double, not long double.
  * Issue #217: fix possible unaligned pointer manipulation, which
    crashes on some architectures (64-bit, non-x86).
  * Issues #64 and #126: when using set_source() or verify(), the
    const and restrict keywords are copied from the cdef to the
    generated C code; this fixes warnings by the C compiler. It also
    fixes corner cases like typedef const int T; T a; which would
    previously not consider a as a constant. (The cdata objects
    themselves are never const.)
  * Win32: support for __stdcall. For callbacks and function pointers;
    regular C functions still don’t need to have their calling
    convention declared.
  * Windows: CPython 2.7 distutils doesn’t work with Microsoft’s
    official Visual Studio for Python, and I’m told this is not a
    bug. For ffi.compile(), we removed a workaround that was inside
    cffi but which had unwanted side-effects. Try saying import
    setuptools first, which patches distutils...

- Update to version 1.2.1
  * No changes entry for this version
- Changes from version 1.2.0
  * Out-of-line mode: ``int a[][...];`` can be used to declare a structure
    field or global variable which is, simultaneously, of total length
    unknown to the C compiler (the ``a[]`` part) and each element is
    itself an array of N integers, where the value of N   *is  * known to the
    C compiler (the ``int`` and ``[...]`` parts around it).    Similarly,
    ``int a[5][...];`` is supported (but probably less useful: remember
    that in C it means ``int (a[5])[...];``).
  * PyPy: the ``lib.some_function`` objects were missing the attributes
    ``__name__``, ``__module__`` and ``__doc__`` that are expected e.g. by
    some decorators-management functions from ``functools``.
  * Out-of-line API mode: you can now do ``from _example.lib import x``
    to import the name ``x`` from ``_example.lib``, even though the
    ``lib`` object is not a standard module object.    (Also works in ``from
    _example.lib import   *``, but this is even more of a hack and will fail
    if ``lib`` happens to declare a name called ``__all__``.    Note that
    ``  *`` excludes the global variables; only the functions and constants
    make sense to import like this.)
  * ``lib.__dict__`` works again and gives you a copy of the
    dict---assuming that ``lib`` has got no symbol called precisely
    ``__dict__``.    (In general, it is safer to use ``dir(lib)``.)
  * Out-of-line API mode: global variables are now fetched on demand at
    every access.    It fixes issue #212 (Windows DLL variables), and also
    allows variables that are defined as dynamic macros (like ``errno``)
    or ``__thread`` -local variables.    (This change might also tighten
    the C compiler's check on the variables' type.)
  * Issue #209: dereferencing NULL pointers now raises RuntimeError
    instead of segfaulting.    Meant as a debugging aid.    The check is
    only for NULL: if you dereference random or dead pointers you might
    still get segfaults.
  * Issue #152: callbacks__: added an argument ``ffi.callback(...,
    onerror=...)``.    If the main callback function raises an exception
    and ``onerror`` is provided, then ``onerror(exception, exc_value,
    traceback)`` is called.    This is similar to writing a ``try:
    except:`` in the main callback function, but in some cases (e.g. a
    signal) an exception can occur at the very start of the callback
    function---before it had time to enter the ``try: except:`` block.
  * Issue #115: added ``ffi.new_allocator()``, which officializes
    support for `alternative allocators`__.
    .. __: using.html#callbacks
    .. __: using.html#alternative-allocators

- update to version 1.1.0 (fate#318838):
  * Out-of-line API mode: we can now declare integer types with
    typedef int... foo_t;. The exact size and signedness of foo_t
    is figured out by the compiler.
  * Out-of-line API mode: we can now declare multidimensional
    arrays (as fields or as globals) with int n[...][...]. Before,
    only the outermost dimension would support the ... syntax.
  * Out-of-line ABI mode: we now support any constant declaration,
    instead of only integers whose value is given in the cdef. Such
    “new” constants, i.e. either non-integers or without a value
    given in the cdef, must correspond to actual symbols in the
    lib. At runtime they are looked up the first time we access
    them. This is useful if the library defines extern const
    sometype somename;.
  * ffi.addressof(lib, "func_name") now returns a regular cdata
    object of type “pointer to function”. You can use it on any
    function from a library in API mode (in ABI mode, all functions
    are already regular cdata objects). To support this, you need
    to recompile your cffi modules.
  * Issue #198: in API mode, if you declare constants of a struct
    type, what you saw from lib.CONSTANT was corrupted.
  * Issue #196: ffi.set_source("package._ffi", None) would
    incorrectly generate the Python source to package._ffi.py
    instead of package/_ffi.py. Also fixed: in some cases, if the C
    file was in build/foo.c, the .o file would be put in
    build/build/foo.o.
- additional changes from version 1.0.3:
  * Same as 1.0.2, apart from doc and test fixes on some platforms
- additional changes from version 1.0.2:
  * Variadic C functions (ending in a ”...” argument) were not
    supported in the out-of-line ABI mode. This was a bug—there was
    even a (non-working) example doing exactly that!
- additional changes from version 1.0.1:
  * ffi.set_source() crashed if passed a sources=[..] argument.
    Fixed by chrippa on pull request #60.
  * Issue #193: if we use a struct between the first cdef() where
    it is declared and another cdef() where its fields are defined,
    then this definition was ignored.
  * Enums were buggy if you used too many ”...” in their definition
- additional changes from version 1.0.0:
  * The main news item is out-of-line module generation:
    + for ABI level, with ffi.dlopen()
    + for API level, which used to be with ffi.verify(), now
      deprecated
- add python-cffi-rpmlintrc: cffi specifically installs C headers
  in site-packages
- add new test dependency gcc-c++
- skip the tests on SLE11 since they fail on i586
