v8.5

This release continues the work on test coverage in pyobjc-core,
resulting in a number of minor bug fixes.

• Added two options to the build_ext command in the setup.py
  of pyobjc-core:

  • --no-lto: Disable link time optimization

  • --no-warnings-as-errors: Disable -Werror

• For struct bindings in frameworks the "in" operator no longer
  swallows exceptions raised by the __eq__ method.

• Improved handing of invalid type encodings for struct types.

• Fix crash while handling a struct wrapper with an invalid
  type encoding.

• Fix handling of empty structs (such as struct foo { }; in
  :func:objc.repythonify.

• The type for NSObject.pyobjc_instanceMethod and
  NSObject.pyobjc_classMethods now supports the GC protocol
  to avoid garbage collection issues when the value for these
  properties is stored as an attribute (which introduces a
  reference cycle)

• PyObjC should work with Python 3.11 alpha release, starting
  at alpha 6. Earlier alpha's are not supported due to reverting
  a workaround for a bug that was fixed in alpha 6.

• NSObject.alloc = 42 now fails. It was already impossible
  to replace a selector by something else through instances
  (NSObject.new().description = 42 raises).

• Added :data:objc.ObjCPointer.typestr with the same
  value as :data:objc.ObjCPonter.type. The latter is now
  deprecated and will be removed in PyObjC 9.

• Better error messages when a class implementing a protocol
  inherits a method of the wrong kind ("class" vs. "instance").

• The value of __slots__ in a class definition is now
  kept in the created class (previous versions always set
  the attribute to an empty tuple).

  This is primarily useful when __slots__ is a :class:dict
  that is used to document attributes.

• Raise the correct exception when the name of a method is
  not an ASCII string.

• :func:objc.loadSpecialVar now better enforces that the
  module_globals argument is a Python dictionary.

• Fixed a crash in :func:objc.loadSpecialVar due to a
  missing pointer dereference.

• pip install pyobjc-framework-... for a framework
  that is not present on the current machine will now
  give a better error message when the "wheel" package
  is not installed.

• Setting an integer option in :data:objc.options to
  a value of an incompatible type (such as a string) will
  now raise an exception as intended, instead of breaking
  the interpreter.

• Trying to delete an attribute from :data:objc.options
  now raises :type:AttributeError instead of :type:TypeError.

• :class:objc.selector now copies the default signature
  from its argument when that argument is another :class:objc.selector.

  Until now this would raise an exception.

• Added some missing error checking in calls to :c:func:PyObject_New
  and :c:func:PyObject_GC_New.

• It is now possible to create an :class:objc.selector from
  a callable that is not a function or bound method. This may
  require specifying the method signature in the call
  to :class:objc.selector.

• For pyobjc-core the build_ext command in setup.py
  now includes the command-line option from the standaard
  command, which means python setup.py build_ext -j 4
  can now be used for parallel builds.

  On my M1 laptop using python setup.py build_ext -j 8
  halves the time needed to build the extension.

• The test command setup.py now supports
  the -v option to print test cases while they are run,
  in previoius versions this required using the --verbosity
  option.

• Improve error handling when dealing with "isHidden" selectors.

• Added pyobjc_hiddenSelectors(classmethods) to :class:objc.objc_class

  This method returns a copy of the dictionary with "hidden" selectors,
  that is Objective-C selectors that are hidden from view.

  The method is primarily a debugging aid for development of
  PyObjC itself.

• #456: ApplicationServices.AXIsProcessTrustedWithOptions and
  Quartrz.CGPDFArrayGetObject had incorrect metadata.

  The testsuites for the various framework bindings now have a test
  that does some basic checks on function and selector metadata. This
  test found the problem with CGPDFArrayGetObject.

• Added :data:objc._C_ATOMIC and :data:objc._C_COMPLEX, both
  extracted from the clang sources after finding some type encodings
  that PyObjC could not decode.

  :data:objc._C_ATOMIC is ignored by PyObjC (for now), and
  :data:objc._C_COMPLEX is not yet supported.

• #456: Fix internal error for _C_OUT argument markup on
  arguments that are CoreFoundation types.

  This can only happen with invalid metadata definitions in framework
  bindings, and earlier versions this resulted in an internal
  assertion error. With this change the "output" argument is always
  None in the result.

• #463: Fix metadata for a number of functions with a C string argument

  The metadata for the following functions was changed to have
  the correct type encoding for string argument, to fix issues with
  using non-ASCII (byte) strings.

  • ApplicationServices.PMWorkflowSubmitPDFWithOptions
  • CoreServices.LocaleRefGetPartString
  • Foundation.NSGetSizeAndAlignment
  • Network.nw_advertise_descriptor_create_bonjour_service
  • Network.nw_browse_descriptor_create_bonjour_service
  • Network.nw_browse_descriptor_get_bonjour_service_domain
  • Network.nw_browse_descriptor_get_bonjour_service_type
  • Network.nw_connection_copy_description
  • Network.nw_content_context_create
  • Network.nw_content_context_get_identifier
  • Network.nw_endpoint_copy_address_string
  • Network.nw_endpoint_copy_port_string
  • Network.nw_endpoint_create_bonjour_service
  • Network.nw_endpoint_create_host
  • Network.nw_endpoint_create_url
  • Network.nw_endpoint_get_bonjour_service_domain
  • Network.nw_endpoint_get_bonjour_service_name
  • Network.nw_endpoint_get_bonjour_service_type
  • Network.nw_endpoint_get_hostname
  • Network.nw_framer_create_definition
  • Network.nw_framer_message_access_value
  • Network.nw_framer_message_copy_object_value

  • Network.nw_listener_create_with_port

  • Network.nw_quic_set_application_error
  • Network.nw_txt_record_access_key
  • Network.nw_ws_options_add_additional_header

  • Quartz.CGContextSelectFont

  • Quartz.CGPDFContentStreamGetResource
  • Quartz.CGPDFDictionaryGetArray
  • Quartz.CGPDFDictionaryGetBoolean
  • Quartz.CGPDFDictionaryGetName
  • Quartz.CGPDFDocumentUnlockWithPassword
  • Quartz.CGPDFScannerPopName
  • Quartz.CGPDFTagTypeGetName

  While fixing this issue I found problems with the metadata for these functions:

  • CoreMIDI.MIDIExternalDeviceCreate
  • CoreMedia.CMBlockBufferAccessDataBytes
  • CoreMedia.CMBlockBufferGetDataPointer
  • CoreMedia.CMBufferQueueInstallTriggerHandler
  • CoreMedia.CMBufferQueueInstallTriggerHandlerWithIntegerThreshold
  • CoreMedia.CMTextFormatDescriptionGetJustification
  • CoreServices.TECGetTextEncodingFromInternetNameOrMIB
  • DVDPlayback.DVDGetScanRate
  • MediaAccessibility.MACaptionAppearanceAddSelectedLanguage

  There's also a new test that checks for this problem in all
  exposed functions.

• Fix incorrect reset of the "inline_list" attribute of the lazy importer,
  this could result in an incorrect TypeError when trying to access
  an non-existing attribute after looking at __all__.

• Fix uniqueness of symbols exposed in the OpenDirectory bindings.

• Unhide manual bindings for Security.SecKeychainFindGenericPassword and
  Security.SecKeychainFindInternetPassword.
