Subject: [PATCH] Fix ABI breakage wrt QAudioSink/Source::stateChanged signals
|

Amends edaec2bf714c98d65f12c8ed9a2ffbd1603635a7, which
|
|
||||||
removed the QAudioSink/Source::stateChanged(QAudio::State)
|
|
||||||
symbols from the API, thus breaking binary compatibility to
|
|
||||||
Qt 6.6. Since moc-generated code compares pointer-to-member-
|
|
||||||
functions, we cannot bring that symbol back and still have
|
|
||||||
such connections work.
|
|
||||||
|
|
||||||
The only reasonable way to fix this is to reverse the
|
|
||||||
namespace aliasing: QAudio is the real namespace, QtAudio
|
|
||||||
becomes an alias. All symbols are then exported with the
|
|
||||||
QAudio type in their signature, even if declared with
|
|
||||||
QtAudio types as parameters, so we don't need any removed_api
|
|
||||||
tricks to bring the old symbols back.
|
|
||||||
|
|
||||||
We just need to trick qdoc into seeing the namespace as
|
|
||||||
QtAudio, which is trivial and has no ABI implications. The
|
|
||||||
previous caveat that string-based connections need to use
|
|
||||||
QAudio doesn't change with this.
|
|
||||||
|
|
||||||
[ChangeLog][Binary Compatibility Note] Qt 6.7.0 broke binary
|
|
||||||
compatibility by renaming the QAudio namespace to QtAudio.
|
|
||||||
Qt 6.7.1 restores compatibility with previous Qt 6 versions
|
|
||||||
again by making QtAudio an alias for the QAudio namespace,
|
|
||||||
but breaks BC with 6.7.0. Code previously built against 6.7.0
|
|
||||||
needs to be recompiled.
|
|
||||||
|
|
||||||
Pick-to: 6.7
|
|
||||||
Fixes: QTBUG-123997
