`super()` is using the MRO to find the first `__init__()` function, if the blender-defined type is not the first inherited type, it may never be called that way.
See #133183
While in theory it would be good to have calls to super classes'
`__del__()` destructors in subclasses, matching the ones to
`__init__()`, several limitations of current CPython implementation do
not make it a practical requirement.
So remove `__del__` from examples, and add a note summarizing the
current problems with using it (aka `tp_finalize` in C++ code).
Also see !132476 for some discussion about that topic.
According to the Python API release notes, this is required now along
with super().__init__() which was already done.
Also fixes mistake in example in API docs.
Pull Request: https://projects.blender.org/blender/blender/pulls/132476
This PR:
* Splits the `Gotchas` page into several sub-sections. This was getting too big and hard to navigate.
* Adds some information regarding Python instances life-time of objects wrapping Blender internal data.
* Adds some information about usage of constructors and destructors for sub-classes of Blender-defined types.
Pull Request: https://projects.blender.org/blender/blender/pulls/129814
Exceptions:
* Links to personal wiki pages
* Pages that are not in the new developer docs yet (like Human Interface Guidelines)
* tools\check_wiki\check_wiki_file_structure.py needs a refactor
The side-bar included both title and description for documentation
pages including quickstart, tips & tricks .. etc.
Titles often wrapped and took up a lot of vertical space in the side-bar.
Now these pages are linked on the main page, with the side-bar
used for top-level Python modules.
We still had a few deprecated assignements of `bpy.props.xxx` to class
members in our API documentation and one of our py tests. Annotations
are to be used now.
Also remove the section about `register_module` utils, this has been
removed in 2.8.
