This prevents these from using abc.ABCMeta metaclass to avoid deprecation warning:
```
DeprecationWarning: Type google._upb._message.MessageMapContainer uses PyType_Spec with a metaclass that has custom tp_new. This is deprecated and will no longer be allowed in Python 3.14.
```

The replacement always_print_without_presence_fields should be used instead, which is very similar but has consistent handling of optional fields by not affecting them.

This copy of `setup.py` is obsolete, as it builds the old C++ backend for Protobuf, which has been deprecated and
unused since 4.21.0 when
[the backend was switch to upb](https://protobuf.dev/news/2022-05-06/#python-updates).
The `setup.py` that we actually distribute in our source packages is located in [`python/dist/setup.py`](https://github.com/protocolbuffers/protobuf/blob/main/python/dist/setup.py). It is not possible to build this `setup.py` directly from the GitHub repo or GitHub release tarball, because it depends on the file layout of our Python source package ([as distributed on PyPI](https://pypi.org/project/protobuf/#files)). The Python source package uses a layout that pulls together all of the things Python needs:
|Python Source Package Path|GitHub Repo Path|Description|
|-----|-----|-----|
|`setup.py`|`python/dist/setup.py`|
|`google/protobuf/*`|`python/google/protobuf/*`|pure Python sources|
|`python/*`|`python/*`|C extension sources|
|`utf8_range/*`|`third_party/utf8_range`|C UTF-8 Validation Library|
|`upb/*`|`upb/upb/*`|C Protobuf Library|
Users who want to build their own Python packages should build from our source package on PyPI, not from our GitHub repo or our GitHub release tarball.
It is also possible to build our source package from GitHub using the following command (this requires Bazel):
```
$ bazel build //python/dist:source_wheel
```

This disables all checks of json_name for upb and protoc under both proto2 and proto3. This option is deprecated that will be removed in future versions, and is only meant as a temporary solution. This also fixes a latent bug in the calculation of camelcase name in Python/upb.
Fixes#12525
PiperOrigin-RevId: 603158026
This flag has consistent behavior between proto2 and proto3 optionals (by not including either one), unlike including_default_value_fields which does include proto2 optional but excludes proto3 optionals.
including_default_value_fields is now deprecated and will be removed in an upcoming release.

Also hardened the text format printer against invalid UTF-8 in string fields. The output string will always be valid UTF-8, even if string fields contain invalid UTF-8.
PiperOrigin-RevId: 600990001
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++.
