Include AddFileDescriptor, AddDescriptor, AddEnumDescriptor,
AddExtensionDescriptor, AddServiceDescriptor.
Those Deprecated APIs may add unlinked descriptors to descriptor_pool which is
is wrong. Should use Add() or AddSerializedFile() instead. Those APIs were
raising deprecated warnings since 2019

`bind()` targets are deprecated and unsupported with Bzlmod. Specifying the dependency directly as a mitigation.
Alternative: Define an `alias()` within `/third_party/BUILD`.

This check enforces that each C++ build target has the correct dependencies for
all headers that it includes. We have many targets that were not correct with
respect to this check, so I fixed them up.
I also cleaned up the C++ targets related to the well-known types. I created a
cc_proto_library() target for each one and removed the :wkt_cc_protos target,
since this was necessary to satisfy the layering check. I deleted the
//src/google/protobuf:protobuf_nowkt target and deprecated :protobuf_nowkt,
because the distinction between the :protobuf and :protobuf_nowkt targets was
not really correct. Neither one exposed the headers for the well-known types in
a way that was valid with respect to the layering check, and the idea of
bundling all the well-known types together is not idiomatic in Bazel anyway.
This is a breaking change, because the //:protobuf target no longer bundles the
well-known types. From now on they should be accessed through the new
//:*_cc_proto aliases in our top-level package.
I renamed the :port_def target to :port, which simplifies things a bit by
matching our internal name.
The original motivation for this change was that to move utf8_range onto our CI
infrastructure, we needed to make its dependency rules_fuzzing compatible with
Bazel 6. The rules_fuzzing project builds with the layering check, and I found
that the process of upgrading it to Bazel 6 made it take a dependency on
protobuf, which caused it to break due to layering violations. I was able to
work around this, but it would still be nice to comply with the layering check
so that we don't have to worry about this kind of thing in the future.

To satisfy the layering check, we need to depend on :gtest for the headers, in
addition to :gtest_main which provides the main() function.
There are a bunch of formatting changes as a side effect of this, but they
should be harmless.

Users should use the add-on unknown_fields.py support.
Old usage example:
unknown_field_set = msg.UnknownFields()
New usage should be:
from google.protobuf import unknown_fields
unknown_field_set = unknown_fields.UnknownFieldSet(msg)

This has been replaced by edition and feature getters. Any code depending on syntax will likely be broken by editions files, and should be migrated to the finer-grained feature helpers.

As a prerequisite of enabling go/protobuf-weak-speed-messages downcasts using built-in cast operations need to be changed to cast functions recommended by protobuf team (go/protobuf-downcast-recommendation)

This also fixes a few minor bugs in the editions implementation that were caught in python/conformance tests, and adds a new SetFeatureSetDefaults API to the def pool for consistency with C++ and other python implementations.

This was already fully implemented in C++, but we need to expose features methods to the Python runtime to fully enable it. This also enables conformance and unit-testing for C++.

This makes third_party/utf8_range no longer a Git subtree, but instead the
permanent location and source of truth for utf8_range. It is also now
incorporated into the @com_google_protobuf Bazel repo. Utf8_range still has its
own separate CMake build for now, though.

There's a test run in test_python.yml that is non-trivial to get working with
Python 3.12 due to some refactoring of our Docker images that would be needed.
But this change updates everything else to add coverage for Python 3.12.
The main changes necessary to get the builds working were to upgrade some Pip
packages via requirements.txt, including in a patch to `rules_fuzzing` that I
plan to upstream soon. I also had to take an explicit dependency on
`setuptools`.
I removed tox.ini, since it was outdated and we have not been actively
maintaining it.
PiperOrigin-RevId: 580548224
This change only covers pure python, and follow-up changes will handle C++/upb variants and actually enable editions support. The C++ one works (as evident from the conformance tests), but needs some APIs added to allow for testing.

This should address the issue in #14600 by avoiding a conflict on with the
`build` directory created by setup.py on a case-insensitive filesystem.
Closes#14600.

Add PyObject_GC_UnTrack() in deallocation functions for Python types that
have PyTPFLAGS_HAVE_GC set, either explicitly or by inheriting from a type
with GC set. Not untracking before clearing instance data introduces
potential race conditions (if GC happens to run between the partial clearing
and the actual deallocation) and produces a warning under Python 3.11.
(The warning then triggered an assertion failure, which only showed up when
building in Py_DEBUG mode; this therefor also fixes that assertion failure.)

Previously we were allocating memory on the message's arena every time we performed a `map[key]` or `map.get(key)` operation. This is unnecessary, as the key's data is only needed ephemerally, for the duration of the lookup, and we can therefore alias the Python object's string data instead of copying it.
This required fixing a bug in the convert.c operation. Previously in the `arena==NULL` case, if the user passes a bytes object instead of a unicode string, the code would return a pointer to a temporary Python object that had already been freed, leading to use-after-free. I fixed this by referencing the bytes object's data directly, and using utf8_range to verify the UTF-8.

Because pure python builds all descriptors at runtime via reflection, it's unable to parse options during the build of descriptor.proto (i.e. before we've built the options schemas). We always lazily parse these options to avoid this, but that still means options can't be *used* during this build. Since the current build process makes heavy use of features (which previously just relied on syntax), this poses a problem for editions.
To get around this, we just embed the resolved features directly into the gencode for this one file. This will allow us to skip feature resolution for these descriptors and still consider features in their build.

Python 3.12 has removed the `distutils` module, so we need to stop relying on
it. Most of the parts we were using had a straightforward replacement in
`setuptools` or elsewhere in the Python standard library. I couldn't find a
good replacement for `distutils.command.clean`, though. We were only using it
to enable `python setup.py clean`, so I just removed that functionality since
directly invoking setup.py is deprecated anyway.
While I was looking at this I realized that our python/release.sh script is
unused, so I also removed that.
