[Pyobjc-dev] [ANN] PyObjC 5.0b1

[Ronald O. <ron...@ma...>]

Hi,

I just uploaded PyObjC 5.0b1 to PyPI. This is the first beta of the version of PyObjC that includes support for macOS 10.14 (Mojave). I expect to release 5.0 soon after the GM release of Xcode 10. 

The primary new “feature” as compared with the 5.0a1 is that this release includes binary wheels for all supported versions of Python (2.7, 3.4, 3.5, 3.6 and 3.7, and for 2.7, 3.6 and 3.7 there are wheels for both the older “intel” installer and the newer 64-bit installer on Python.org) 

Changes w.r.t. PyObjC 5.0a1:

* Bindings updated for Xcode 10 beta 6.

* Add a custom binding for a number of structure types in
  CoreAudio:

  - AudioBuffer
  - AudioBufferList
  - AudioChannelDescription
  - AudioChannelLayout
  - AudioValueTranslation

  With this patch using APIs with these types should actually
  work.

* PR19: Fix deprecation warning in bridgesupport support module

  Patch by: Mickaël Schoentgen

* Creating objc.ObjCPointer instances now results in a
  Python warning, instead of an unconditional message on
  stdout.

  .. note::

     The creation of these objects is a sign that APIs are
     not wrapped correctly, these objects are created for
     pointers where the bridge doesn't know how to handle
     them properly.

* System bridgesupport XML files (normally not used by PyObjC)
  can contain constant numbers with value "inf", PyObjC now
  knows how to handle those.

* Added bindings for the "Metadata" subframework of the
  "CoreServices" framework.

* Added bindings for the "CarbonCore" subframework of the
  "CoreServices" framework.

  Most APIs in this subframework are not available to Python,
  only those APIs that are not deprecated and seem interesting
  are exposed.

* The separate framework wrappers DictionaryServices,
  LaunchServices and SearchKit are deprecated, use
  the CoreServices bindings instead.

  These framework wrappers still exists, but are effectively
  aliases for CoreServices with this release. Because of this
  these bindings can expose more symbols than previously.

* Fix unexpected exception when trying to call getattr
  on a framework wrapped with a name that isn't a valid
  identifier.

* #244: Bad metadata for CGPDFOperatorTableSetCallback

* #247: Fix crash in regression test case

  One specific test in pyobjc-core crashed the interpreter
  when run separately. Because of this I've disabled an
  optimization that uses alloca instead of PyMem_Malloc to
  allocate memory for now.
