This copy of `setup.py` is obsolete, as it builds the old C++ backend for Protobuf, which has been deprecated and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.

The previous limit of 127 was causing error messages to get truncated when long identifiers are in use.
This will increase the stack usage of any code that is allocating a `upb_Status` on the stack. If we want to support smaller stacks in the future, we could change `upb_Status` to store its capacity inline, so different users can allocate error buffers with different capacity.

Protobuf php lib encodes 123_000_000 nano like this: 2000-01-01T00:00:00.**123**Z but then it gets decoded into 123 nanoseconds instead of 123_000_000.
There were issue opened some time ago that also describes this behaviour #4335Closes#12396

for Edition 2023 and beyond.
Since ctype option is visible to all languages than just C++, this CL moves
the ctype validation to DescriptorBuilder for Edition 2023 and beyond. This
may cause failures to proto files that were never built for C++ but still
have the issue. Note that this CL does not affect proto2 or proto3.

The PHPDoc escaping in PHP is aggressive in that it escapes some character sequences that don't need to be escaped (`/*`), and it uses HTML entities to escape others (`*/` and `@`) instead of the recommended PHPDoc escape sequences.
For Example, in [`Google\Api\RoutingParameter`](https://github.com/googleapis/common-protos-php/blob/main/src/Api/RoutingParameter.php#L42):
```
* path_template: "projects/*/{table_location=instances/*}/tables/*"
```
Should be escaped as:
```
* path_template: "projects/{@*}{table_location=instances/*}/tables/*"
```
according to [the PHPDoc guide](https://manual.phpdoc.org/HTMLframesConverter/default/phpDocumentor/tutorial_phpDocumentor.howto.pkg.html#basics.desc):
- For `@`: "if you need an actual "@" in your DocBlock's description parts, you should be careful to either ensure it is not the first character on a line, or else escape it ("\\@") to avoid it being interpreted as a PhpDocumentor tag marker."
- For `*/`: " If you need to use the closing comment "\*/" in a DocBlock, use the special escape sequence "{@*}."

Crate names must not contain '-'. So we replace any '-' by a '_' to form a valid crate name.
Bazel supports many special characters as target names: !%-@^_"#$&'()*-+,;<=>?[]{|}~/. We don't have to support all of them in Protobuf Rust, but '-' seems used widely enough and is a common alternative to '_' in naming.

Add convenience _opt for singular message fields.
Users can detect if the message is set or unset, and unwrap via into_inner.

This is the final CL (part 4 of 4) in the ProxiedWithPresence chain.
In the past, we had returned Mut directly for the `_mut` accessors.
This was a temporary engagement in order to get the other submsg machinery checked in.
As we prep for the finalization of v0.6, we can finally conform to the rest of the `_mut` getters.
$field$_mut now correctly returns $pb$::FieldEntry<'_, $msg_type$> as a part of this.
All test callsites have been updated to `.or_default` in order to test the mutational pathway as before.

The old flag accidentally had inconsistent behavior between proto2 optional and proto3 optional fields, the new flag treats them consistently (and is consistent with the preexisting behavior of the Go JSON serializer).

# Motivation

This is for completeness - I am not blocked by this change in any way, so feel free to close the PR or treat is a low priority.
# Changes
Implement JsonIgnoreUnknownParsingTest in C# conformance test runner.

It seems possible that old data is stored with serialized descriptors. If we
reject old descriptors due to invalid ctype, the change effectively becomes
breaking changes. We should apply this stricter check for edition 2023 or beyond.

There are no restrict calls, so the manifest asserts that.
The CocoaPods support now ensures you are using CocoaPods >= 1.12 as that
avoids all the know bugs in CocoaPods support needed to capture the
Privacy Manifest in a resource bundle.

Instead of silently ignoring `[ctype = XXX]` for non string or bytes fields,
this CL starts failing to build descriptors to call out the issue. This may
cause failures to existing proto schemas but fixing them should be straightforward.

right kind of extension. This way you get a compile time failure instead of a
runtime one.
Other extension accessors already have this kind of SFINAE restrictions.

RepeatedPtrField had been updated to handle Add/MergeFrom when holding an abstract type MessageLite, hence ExtentionSet no longer needs to have custom workarounds.

CocoaPods fails spec validation for some warnings, so use a local
to avoid warnings for 64->32bit implicit conversions. This comes up
for watchOS builds.
