Pyobjc

* Update metadata for Xcode 9.4 beta 2 (no changes)

* Restore autodetection of --with-system-ffi, but ignore this python setting
for /usr/bin/python because Apple doesn't ship libffi headers.

* Add bindings to the BusinessChat framework introduced in macOS 10.13.4

* Update metadata for Xcode 9.3

* Issue 233 Fix crash in Security.AuthorizationCopyRights() wrapper

* Issue 234 Fix crash in AuthorizationExecuteWithPrivileges() wrapper

Reported by Vangelis Koukis

* Ensure doctest can work with modules containing subclasses of NSObject

Reported by Just van Rossum

* Issue 236 : Importing can sometimes fail in multi-threaded scenarios

Fix by Max Bélanger

* Undeprecate treating struct wrappers as sequences. Removing this feature would
break too much existing code, hence deprecating is not really an option. Furthermore,
this would also break some nice idioms.


* Pull request 17: Fix python 3 issues in PyObjCTools.AppHelper and PyObjCTools.Conversion

Fix by Max Bélanger

* Protection agains buffer overflow and negative indexes in
``__getitem__`` and ``__setitem__`` for ``objc.varlist`` instances.

* Fix incorrect metadata for ``+[NSEvent addLocalMonitorForEventsMatchingMask:handler:]``

* Fix incorrect and misleading error message in the exception
that is raised when return a value from a block that should not
return a value.

* Issue 223: Fix hard crash when executing ``help(Cocoa)``

Fetching the help for PyObjC framework wrappers isn't very useful due
to the sheer size of the output (4.5 million lines of output for
``help(Cocoa)`` at the moment), but shouldn't cause a hard crash of
the interpreter.

* Issue 218: Explictly cause an ImportError when reloading objc._objc

Reloading the PyObjC core extension now raises an ImportError because
this cannot work and used to raise a rather vague error.

* Updated metadata for Xcode 9.2

* Added missing MAC_OS_X_VERSION_* constants

* Fix memory error in struct wrappers which resulted in
a use-after-free error in the initializer for structs.

* 135: Add bindings for frameworks :doc:`Security </apinotes/Security>`,
:doc:`SecurityFoundation </apinotes/SecurityFoundation>` and
and :doc:`SecurityInterface </apinotes/SecurityInterface>`.

The bindings for the Security framework don't expose a
number of older APIs that were deprecated in macOS 10.7.

* 129: Add bindings to libdispatch.

These bindings require macOS 10.8 or later, libdispatch was
available earlier but macOS 10.8 changed the API in such a
way that wrapping became a lot easier.

* Issue 213: Fix signature for -[NSObject forwardInvocation:]

Reported by user "pyrocat"

* Updated metadata for Xcode 9.1

* Changes to PyObjCTools.TestSupport to be able to include/exclude tests
based on the minor release of macOS.

* Some tweaks to fix test failures when running on OSX 10.5, 10.6, 10.9.

NOTE:

The stacktrace formatting of in ``PyObjCTools.Debugging`` (from the
ExceptionHandling bindings) don't work for PPC binaries because symbol
resolution doesn't work.

This is a known issue that won't be fixed.

* Issue 204: Metadata for CGPDFDictionaryGetObject was wrong

Reported by Nickolas Pohilets.

* Updated metadata for Xcode 9 GM.

* Fix 202: Add bindings for ``CGPDFDictionaryRef``, ``CGPDFScannerRef``
``CGPDFStreamRef`` and ``CGPDFStringRef`` to the Quartz bindings (including
some minor updates to function metadata)

Reported by Nickolas Pohilets.

* Issue 205: Add ability to read bytes from ``objc.varlist``

Instances of ``objc.varlist`` now have a method to return a memoryview
that refers to the first section of the list::

def as_buffer(self, count : int) -> memoryview

This returns a memoryview the references the underlying memory for
the first *count* elements in the list.

Reported by Nickolas Pohilets.

* Added bindings for the :doc:`GameKit </apinotes/GameKit>` framework introduced in macOS 10.8.

* Added bindings for the :doc:`GameplayKit </apinotes/GameplayKit>` framework introduced in macOS 10.11.

Note that these bindings are less useful than they could be because
PyObjC currently does not support "vector" types that are used in
some APIs.

* Removed PyObjCTools.TestSupport.filterWarnings, use warnings.catch_warnings
instead.

* Building pyobjc-core using "python setup.py develop" will use 'ccache'
when available.

* Building pyobjc-core will compile the source files from new to old files,
to speed up feedback while working on the source code.

* Legacy BridgeSupport files on macOS 10.13 (which aren't used by default
by PyObjC) can contain junk data in typestring data. Cleanup that data
before using it.

* Deal with loading bundle variables of a C string type, that used to crash
to do an oddity of locating that information.

* Using wrappers for C structs as sequences is deprecated, this
feature was introduced a long while ago when the framework wrappers
were very incomplete and is no longer usefull.

* Add ``objc.options.structs_indexable``. When this option is True
(the default) wrappers for C structs behave as before, when the
option is False these wrappers can no longer be used as writable
tuples, that is all "sequence" methods will raise ``TypeError``.

* Add ``objc.options.structs_writable``. When this option is True
(the default) wrappers for C structs behave as before, when the
option is False these wrappers can no longer be modified.

* Add availability macro ``MAC_OS_X_VERSION_10_13`` to ``objc``.

* New framework wrappers:

- :doc:`ColorSync </apinotes/ColorSync>` (new in macOS 10.13)
- :doc:`CoreML </apinotes/CoreML>` (new in macOS 10.13)
- :doc:`ExternalAccessory </apinotes/ExternalAccessory>` (new in macOS 10.13)
