12.2

Update framework bindings for macOS 26.5 SDK

The following code failed at the last line in previous versions:

 class MyObject(NSObject):
     pass

 obj = MyObject()
 obj.alloc = MyObject.alloc
 print(obj.alloc) # Raised AttributeError
Backward incompatible changes: CFBagCreate and CFBagCreateMutable now match the \ 
API in Objective-C, that is, a value for the callbacks argument must be passed \ 
(must be kCFTypeBagCallBacks).

* Fix retain count management for the callbacks registered with \ 
DARegisterDiskEjectApprovalCallback, DARegisterDiskMountApprovalCallback, and \ 
DARegisterDiskUnmountApprovalCallback in DiskArbitration bindings.

“Hidden” instance methods were not hidden when looking them up as an \ 
attribute on the class, but found an unbound method as if the method was not \ 
hidden.

“Hidden” instance methods were visible in dir(SomeClass).

* Fix anObject.methodForSelector_(some_selector) resolving to a class method IMP \ 
when a bound selector object for some_selector is a class attribute.

Fixed some memory leaks on unlikely error paths.

* numbers.Number values are proxies as an NSNumber value.

* the new of Objective-C classes now also support keyword arguments derived from \ 
class selectors of the form valueWithKey1:key2: (with an arbitrary prefix \ 
instead of value).

The following calls are now possible (as examples):

Foundation.NSHost(address="www.python.org"), returns \ 
Foundation.NSHost.hostWithAddress_("www.python.org").

AppKit.NSImage(systemSymbolName="multiply.circle.fill", \ 
accessibilityDescription="multiply icon"), returns \ 
AppKit.NSColor.colorWithSystemSymbolName_accessibilityDescription_("multiply.circle.fill", \ 
"multiply icon").

Add NSMutableData.take_bytes on Python 3.15 to mirror the new bytearray method \ 
of the same name.

Rewrite the construction of objects representing method and function metadata, \ 
this should result in (slightly) less memory usage.

This release gets the testsuite for pyobjc-core to a point where there is \ 
comprehensive test coverage for the entire bridge. All extension modules now \ 
have 100% test coverage according to lcov, although with use for exclusion \ 
comments to ignore code blocks that cannot be reached for various reasons (e.g. \ 
PyDict_New can fail, but that only happens when running out of memory and it not \ 
preproducable during testing).

This enables refactoring the code in pyobjc-core with more confidence that this \ 
won’t result in unexpected changes in behaviour.

Fix error message for invalid argument to a callable with a variable length \ 
output buffer argument.

Fix error handlign for incomplete struct encodings.

Raise better error when specifying a negative array size for (Objective-)C \ 
arguments where the size of a buffer is passed as one of the arguments to a \ 
method or function.

A side effect of this is that a number of manual bindings no longer support \ 
passing -1 as the size of a buffer to derive the size from the Python sequence.

A Python implementation for a method that returns void and has a single output \ 
parameter used to leak a reference to the return value.

Fix crash when a Python implementation with a pass-by-reference output argument \ 
or return value returns an Objective-C instance that is no longer referenced in \ 
Python when the function returns, e.g.:

@objc.objc_method(signature=b"@@:o^@")
def myOutput_(self, a):
    return (1, NSObject.alloc().init())
The bridge could pass a null pointer for a function pointer argument in some \ 
(unlikely) edge cases instead of raising an error.

Fix various crashes related to edge cases in pass-by-reference argument handling \ 
(none of which happen are used in bindings for Cocoa frameworks)

Metadata with a tuple as the value for c_array_length_in_arg for an output \ 
argument is now honored for methods implemented in Python.

Fix crash when c_array_length_in_arg metadata refers to an non-existing argument.

Fix handling of transient proxy value, such as when Objective-C calls a Python \ 
method when the object is kept alive from Objective-C (no active reference in \ 
Python).

Edge case found while debugging an unexpected crash in the free-threaded build \ 
which uncovered a bug that also affected the regular build (but was not \ 
triggered there in the test suite).

aValue.methodForSelector_ now works when the selector is implemented in Python, \ 
the result will be the Python callable (not wrapped in an objc.IMP value).

* A number of constants in the CoreAudio bindings evaluated to byte strings, \ 
while the framework expects regular strings.

Foundation.NSDecimalNumber can no longer be subclassed in Python.

Subclasses was possible in older versions, but this is something that isn’t \ 
supported in Objective-C and has unexpected behaviour.

The cobject and c_void_p arguments for opaque pointer types and objc.objc_object \ 
are now keyword only.

This should not affect user code because passing these values by value isn’t \ 
useful (esp. because the c_void_p argument is the only one that’s useful for \ 
interop with 3th-party code).

* “frozendict” is supported with Python 3.15a7 and later.

Instances roundtrip to Objective-C objects similarly as the dict type, including \ 
for keyed archiving. For non-keyed archiving a frozendict value is read back as \ 
a plain dict.

The metadata method on objc.function, objc.selector, and objc.IMP now returns a \ 
frozendict instead of a regular dict to indicate that changing the value has no \ 
effect.

* Drop GIL when sending KVO notifications

PR by github user Max Bélanger.Update framework bindings for macOS 26.5 SDK

Log message:
py-pyobjc: updated to 12.1

12.1

12.0 incorrectly has support for Python 3.9 in
packaging metadata.

Update framework bindings for the macOS 26.1 SDK

Instances of :type:bytearray can be used as the argument for
a function or selector that expects a null-terminated C char array.

Automatically disable KVO usage for subclasses of NSProxy defined
in Python.

Fix SystemError when calling objc.propertiesForClass(objc.objc_object).

objc.classAddMethods no longer supports callable's whose __name__
attribute is a byte string.

Clearer error messages when an entry in the methods added with
objc.classAddMethod is invalid.

Using objc.classAddMethods to add a method for which a custom
IMP helper has been registered now works correctly (previously
the default libffi IMP implementation was used in these cases),
and likewise for using :funcsetattr to assign methods.

It is no longer possible to use :func:objc.classAddMethods to
override an existing method with an incompatible Objective-C signature,
and likewise for using :func:setattr to do the same.

It was already not possible to override a method from a super class
with an incompatible Objective-C signature.

It is now possible to use an :class:objc.objc_method instance
in the method list argument for :func:objc.classAddMethod.

-[OC_PythonObject copy] now actually copies the value if the
value is not known to be immutable (such as subclasses of the
builtin number types).

Log message:
py-pyobjc*: updated to 11.1

11.1

The major change in this release is aligning behaviour of the core bridge
with clang's documentation for automatic reference counting \ 
<https://clang.llvm.org/docs/AutomaticReferenceCounting.html>_
for initializer methods. In particular, PyObjC now correctly models
that methods in the "init" family steal a reference to self and return
a new reference.

Log message:
py-pyobjc*: fix for setuptools>=78; bump revisions

Log message:
py-pyobjc: updated to 11.0

Version 11.0
The major change in this release is experimental support for free-threading (PEP \ 
703) which was introduced as an experimental feature in Python 3.13.

This required fairly significant changes in the core of PyObjC to change C \ 
Python API use and PyObjC internal APIs (mostly related to the use of borrowed \ 
references).

Dropped support for Python 3.8. PyObjC 11 supports Python 3.9 and later.

Updated metadata for the macOS 15.2 SDK, including bindings for the following \ 
frameworks:

MediaExtension
DeviceDiscoveryExtension
Added minimal bindings to the Carbon framework.

At this time only some functions and constants related to hotkeys are available. \ 
Please file an issue if you have a usecase for other APIs.

Struct wrappers now support a number of functions from copy: copy.replace() (new \ 
in Python 3.13), copy.copy() and copy.deepcopy().

The __pyobjc_copy__ method has been removed from struct wrappers. This was never \ 
a public API. Use copy.deepcopy() instead.

objc.FSRef.from_path`() now supports os.PathLike values as its arguments (as \ 
well as strings).

Experimental support for the free-threading mode introduced in Python 3.13.

The core bridge and framework bindings claim compatibility with free-threading \ 
as introduced as an experimental feature in Python 3.13.

The support in PyObjC is also an experimental feature: I’ve reviewed code for \ 
free-threading issues and adjusted it where needed, but the code has seen only \ 
light testing w.r.t. concurrency.

Some functionality that’s explicitly not thread-safe:

Defining an Objective-C class with the same name in multiple threads concurrently.

Splitting calls to alloc and init and calling init multiple times concurrently. E.g.:

import threading
from Cocoa import NSObject

v = NSObject.alloc()

t_list = []
for _ in range(2):
    t = threading.Thread(target=lambda: v.init())
    t_list.append(t)
    t.start()

for t in t_list:
    t.join()
The internal mapping from Python values to their active Objective-C proxy value \ 
now uses weak references. This should not affect user code, other than being a \ 
bit more efficient.

The internal interfaces for updating this mapping, and the reverse mapping from \ 
Objective-C values to their active Python proxy was changed to remove a small \ 
race condition. This was required for free threading support, but could in \ 
theory also bit hit when using the GIL.

The data structure for mapping Python values to their Objective-C proxy has been \ 
rewritten to support free threading. This also simplifies the code, and should \ 
be small performance improvement for the regular build of Python.

The TypeError raised when passing a non-sequence value to some APIs implemented \ 
in C now has a __cause__ with more detailed information.

This is a side effect of dropping the use of PySequence_Fast in the \ 
implementation of PyObjC.

Removed objc.options._nscoding_version, a private option that is no longer used.

Changing the __block_signature__ of a block value when the current value of the \ 
signature is not None is no longer possible.

Please file an issue if you have a use case for changing the signature of a block.

Fix compatibility with Python 3.14 (alpha 3)

Removed private function objc._sizeOfType because its unused.

Fix memory leak when using Python callables as blocks.

The memory leak also resulted in leaking a reference to the callable (and hence \ 
anything kept alive by that reference).

The generic __new__ implementation now works as intended when registering \ 
methods that other than init... methods.

Dropped ‘%n’ support in handling printf-format strings for variadic \ 
functions and methods.

Two reasons for that: 1) supporting this properly should return the value \ 
writing to the %n location (requiring significant changes) and 2) Apple’s \ 
libraries require using static strings for ‘%n’ to work (at least on some \ 
platforms and versions of the OS)

Fix manual bindings for AVAudioPCMBuffer methods for getting channel data \ 
(floatChannelData, int16ChannelData and int32ChannelData)

fix broken bindings for CGWindowListCreateImageFromArray.

The private __is_magic attribute on objc.objc_object has been renamed to \ 
__pyobjc_magic_coookie__.

Various fixes to edge case behaviour that were found while improving test coverage.

Log message:
py-pyobjc*: updated to 10.3.1

Version 10.3.1

Ensure __init__ can be used when user implements __new__.

Version 10.3 dropped support for calling __init__, but that breaks a number of \ 
popular projects. Reintroduce the ability to use __init__ when a class or one of \ 
its super classes contains a user implemenentation of __new__.

Code relying on the __new__ provided by PyObjC still cannot use __init__ for the \ 
reason explained in the 10.3 release notes.

Log message:
py-pyobjc*: updated to 10.2

Version 10.2
Fix a number of warnings found by adding -Wpendantic to the CFLAGS for pyobjc-core

Fix undefined behaviour warnings:

Suppress the undefined behaviour warning about out of range values in double to \ 
(unsigned) long long in the OC_PythonNumber implementation as these are \ 
unavoidable when matching NSNumber behaviour.
Switch to using memcpy instead of direct assignment in converting plain C values \ 
to/from Python because “packed” structs might result in accessing values \ 
through unaligned pointers.
Updated bindings for the macOS 14.4 SDK (Xcode 15.3)

Added bindings for the “BrowserEngineKit” framework on macOS 14.4 or later.

Add obj.registerPathType() to register a Python type as a path like type with \ 
PyObjC. By default only pathlib.Path is registered as such.

A minor backward compatibility issue is that instances of the registered types \ 
will be written to NSArchive and NSKeyArchive archives as instances of NSURL and \ 
won’t roundtrip back to the original Python type. This might change in future \ 
versions of PyObjC, at least for pathlib.Path.

Instances of pathlib.Path (and other types registered with \ 
objc.registerPathType) are bridged into Objective-C as instances of NSURL.

This means that these types can be used as values passed to APIs expecting a \ 
filesystem URL, e.g.:

```python

path = pathlib.Path(“/Applications/Numbers.app”) bundle = \ 
NSBundle.bundleWithURL_(path) ```

Fix some warnings in pyobjc-core when testing with Python 3.13a4.

Add support for NSBezierPathElementQuadraticCurveTo in \ 
NSBezierPath.elementAtIndex_associatedPoints_.

Fix compilation error in pyobjc-framework-Cocoa with a recent deployment target.

Log message:
py-pyobjc*: updated to 10.1

Version 10.1
Upgrade framework bindings for the macOS 14.2 SDK

Make sure the install.py and develop.py scripts in the repository work when run \ 
out of tree.

os.fspath(someURL) will not work with Cocoa URLs (NSURL, CFURLRef) that refer to \ 
local filesystem paths. TypeError will be raised for other URLs.

This enables using regular Python filesystem APIs with URLs that refer to local \ 
filesystem paths.

Fix compilation issue when building on macOS 13 or earlier

Fix build error on ancient macOS versions where clang doesn’t support -flto=thin.

Add a workaround for a crash in pyobjc-core when running the testsuite on macOS \ 
10.14.

Fix some issues found while running the testsuite on macOS 10.9 to macOS 13, \ 
instead of only testing on the latest macOS version. Most issues found where \ 
problems in the testsuite itself, but not all.

Some of the changes skip tests on older macOS versions (10.12, 10.13 and 10.14) \ 
due to running into what appears to be crashing platform bugs.

Fix dependencies between framework binding packages

Fix build error with the current Python 3.13 alpha release (3.13a2).
