In Nautilus 43, NautilusFile is no longer available (in the past, NautilusFileInfo was its alias).

https://gitlab.gnome.org/GNOME/nautilus/-/commit/7e2605c681d065e6b0a3d779c30b892932597991

Similarly, the old names of interfaces that were renamed to use Interface suffix instead of Iface
will not be available in Nautilus 43.

That way, we can easily test them and apply other development tools.

In Python 3 urllib was split into multiple libraries,
we do not need to support the Python 2 variant any longer.

It was not used for anything since https://gitlab.gnome.org/GNOME/nautilus-python/commit/d14849670f834e81f2061afc1e6879c6a166379b.

So that the style is consistent.

This will make it easier to port to Meson.

Previously, they were just empty.

nautilus-python-object.c: Remove the extra reference on the PyObject file wrappers when adding them to the python list

PyObjects start with a refcount of 1. Adding them to a PyList adds a second - which gets removes during the list's destruction. The additional ref was keeping its associated NautilusFile from ever being finalized.

Steps to reproduce problem:

1) Install nautilus-python and some python MenuProvider extension.
2) Create a folder with a couple of image files inside. Be sure to allow thumbs to generate.
3) Enter the folder, select one or more files (so menus are generated). De-select and leave the folder (but do not close Nautilus). If you were to watch for the files' finalize to run, you'd notice it does not.
4) touch or otherwise modify one of the image files from a terminal
5) Re-enter the folder in nautilus.
6) See that loading status runs forever, modified file(s) never display. Note: even if you only modify one file, it could cause all of the files to fail to load, depending on their order during enumeration.

When no more views are displaying a file, that file should be finalized. When it's not it ends up in an undefined state, as it has no monitors flag it as needing to be updated.

It is no longer supported.

PyObject_GetAttrString() returns new reference:

https://docs.python.org/3/c-api/object.html#c.PyObject_GetAttrString

We install all other extensions from docs. Also correct the name.

When overriding constructors, we need to call the parent constructor, otherwise GObject will not be properly initialized:

>>> from importlib import import_module; ufia = import_module('examples.update-file-info-async')
>>> ufia.UpdateFileInfoAsync()
<update-file-info-async.UpdateFileInfoAsync object at 0x7f5fe326b5c0 (uninitialized at 0x(nil))>


Furthermore, we can drop the constructors where we are not initializing any extra properties –
then the constructor of the parent class (GObject will be called).

We also need to ensure that GObject is the first parent class listed since otherwise,
Python will try to call the constructor of the provider, which does not exist since it is an abstract class.

We will keep it for TestExtension since it is the first example people reading the docs will see
and hopefully that will reduce the amount of forgotten parent constructor calls.


Noticed in https://github.com/linuxmint/nemo-extensions/commit/67a5d42489a1ae1715f620f281b62b8cc444d2d0

This should make it clearer what each function does, even though they are not checked.

Also switched the tuples for proper lists since the API expects `GList`s.

Picked from https://github.com/linuxmint/nemo-extensions/commit/bd48a2da9012f81e0e3a1a09ca0069947a198de5

The `CONVERT_LIST` part is already merged as https://gitlab.gnome.org/GNOME/nautilus-python/-/merge_requests/8

The `Py_XDECREF(py_uri)` is not necessary since `N` arguments of `PyObject_CallMethod` do not increase reference count https://docs.python.org/3/c-api/arg.html#c.Py_BuildValue
It would cause a crash and was reverted in https://github.com/linuxmint/nemo-extensions/commit/74b9e778cfa71daa619e16b3c4f945d2725d24e2.

Formatted with Prettier.

Mostly removed GTK-based API:
https://gitlab.gnome.org/GNOME/nautilus/-/merge_requests/927

This replaces NautilusPropertyPageProvider from Nautilus-3.0.
