Ref: https://bugs.ruby-lang.org/issues/20311
C global variable that contain references to Ruby object MUST be declared to the Ruby GC to prevent these objects from being collected or moved.
There are a few exceptions to that, such as classes defined using the C APIs such as `rb_define_class` etc.
Up to Ruby 3.4 however, there was a bug that caused classes created from Ruby with the `Struct.new("Name")` API to also be marked as immortal and immovable.
GRPC has been relying on this bug, which I fixed in Ruby 3.4, and now GRPC is crashing when `Struct::Status` is moved around by the GC.

PiperOrigin-RevId: 616152904
In grpc v1.46.2 and later versions, #29155 caused the Ruby client to return `GRPC::Core::CallError`, a non-standard error, with a message: `grpc_call_start_batch failed with outstanding read or write present (code=8)`. However, the actual error should have been `GRPC::DeadlineExceeded`. This occurred because when `GRPC::DeadlineExceeded` is raised, the `@metadata_received` flag doesn't get flipped. When `receive_and_check_status` runs to determine
the error, the `RECV_INITIAL_METADATA` is erroneously sent again.
To avoid this, flip the flag in an `ensure` block whenever the `RECV_INITIAL_METADATA` op is set.

As announced in https://discourse.llvm.org/t/clang-16-notice-of-potentially-breaking-changes/65562, clang 16 defaults `-Wincompatible-function-pointer-types` to be on. This causes a number of hard errors due to implicit conversions between `void *` and `void`, such as:
```

`GPR_BACKWARDS_COMPATIBILITY_MODE` was devised to support old Linux kernel with old glibc but gRPC is now expected to support glibc 2.17 and later (2.17 is derived from the oldest but supported Linux distro, CentOS 7). Effectively, gRPC doesn't need `GPR_BACKWARDS_COMPATIBILITY_MODE` anymore. Hence, let's remove it.
gRPC Python and Ruby that distribute binary artifacts already began to use `manylinux` environment dealing with this issue in a better way so they don't need this flag anymore.
Closes#35602

The `grpc_channel_args` is retained on the Ruby object and used for recreating the channel after forking in
grpc_rb_channel_maybe_recreate_channel_after_fork(). Previously, the key for each argument was taken from a Ruby string directly, which could be invalidated if the Ruby string is modified or moved by the GC. Duplicate the string for the key instead, so we own it.

This commit upgrades gRPC to protobuf v25.0 and makes some fixes to
account for upb changes. One major change is that upb has been merged
into the protobuf repo, so we can now drop the separate `@upb`
dependency. Another is that `.upb.c` files no longer exist and there are
new `.upb_minitable.h` and `.upb_minitable.c` files. The longer
filenames exceeded a Windows restriction, so to work around that I
renamed the `upb-generated` directory to just `upb-gen`, and likewise
for `upbdefs-generated`.
Currently it is very easy to use the `TlsCredentialsOptions` in such a
way that it produces a memory leak. For example, the code block
```
{
TlsCredentialsOptions options;
}
```
produces a memory leak. This PR fixes up the ownership bugs in this
class and its `grpc_tls_credentials_options`, the C-core analogue.
Introduce `grpc-native-debug` gems containing debug symbol packages that
complement the shared libraries shipped in pre-compiled binary gems.
src/ruby/nativedebug/README.md has details on usage.

https://github.com/grpc/grpc/pull/33538 added `-weak_framework
CoreFoundation` in `DLDFLAGS` for only `arm64-darwin` builds, but the
issue reported in https://github.com/grpc/grpc/issues/33483 can also
happen on `x86-darwin` builds. This can happen if:
1. The Ruby interpreter is compiled without
`-Wl,-undefined,dynamic_lookup`.
2. This happens if the Ruby interpreter is built with XCode 14.0 to 14.2
(https://bugs.ruby-lang.org/issues/19005).
Simplify the logic and always include `-weak_framework CoreFoundation`
for macOS builds.
grpc 1.57.0 crashes win ruby and alpine due to no `strdup` in musl libc.
This diff replace `strdup` with `grp_strdup`

This was done manually due to a problem with
`tools/distrib/python/make_grpcio_tools.py`. ~I fixed it in this PR
(depends on cl/547979185), so there is a fair chance this upgrade will
work normally for the next release.~ The fix may be problematic for
upgrading protobuf on older release branches, so the improvement will be
worked on separately. CC @jtattermusch
This also updates the UPB dep to the latest commit on the 23.x branch.
So far, we've structured global C-core init/shutdown as follows:
1) every grpc-ruby object calls `grpc_init` when allocated, and
`grpc_shutdown` when finalized
2) grpc-ruby background threads are each wrapped in a
`grpc_init/shutdown` pair - for example see
b32d94de05/src/ruby/ext/grpc/rb_event_thread.c (L122)
and
b32d94de05/src/ruby/ext/grpc/rb_event_thread.c (L136)
But because ruby doesn't join ruby threads when the process is
terminating, the `init/shutdown` pairs in 2) are always left open. I.e.,
thus far we have never been invoking the final call to `grpc_shutdown`
which actually does C-core global shutdown. Thus our calls to
`grpc_shutdown` are useless.
So we might as well keep things simple and not even attempt to call
`grpc_shutdown`. Now we just call `grpc_init` before using C-core, and
then never even attempt global shutdown (in non-forking situations).
As a bonus, this fixes the issue with the event thread's
`grpc_ruby_init` racing with `prefork` that is mentioned in
https://github.com/grpc/grpc/pull/33666
Adds experimental fork support to gRPC/Ruby
Works towards https://github.com/grpc/grpc/issues/8798 (see caveats for why this wasn't marked fixed yet)
Works towards https://github.com/grpc/grpc/issues/33578 (see caveats for why this wasn't marked fixed yet)
This leverages existing `pthread_atfork` based C-core support for
forking that python/php use, but there's a bit extra involved mainly
because gRPC/Ruby has additional background threads.
New tests under `src/ruby/end2end` show example usage.
Based on https://github.com/grpc/grpc/pull/33495
Caveats:
- Bidi streams are not yet supported (bidi streams spawn background
threads which are not yet fork safe)
- Servers not supported
- Only linux supported
Remove `src/ruby/ext/grpc/objs/` and strip `src/ruby/ext/grpc/libs/` in
ruby build dir to save some space.
This can reduce the grpc gem size from more than 1G to about 70~80M.
This only affects opt build, dbg build remains the same.
A proper fix maybe use the same makefile to build c-core and the
extension rather than building c-core when generating the extension
makefile.

This PR does the following: for the TLS server credentials, stops
calling `SSL_CTX_set_client_CA_list` by default in
`ssl_transport_security.cc`, and gives users a knob to re-enable calling
this API.
## What does the `SSL_CTX_set_client_CA_list` API do?
When this API is called, a gRPC TLS server sends the following data in
the ServerHello: for each certificate in the server's trust bundle, the
CA name in the certificate.
This API does not change the set of certificates trusted by the server
in any way. Rather, it is just providing a hint to the client about what
client certificate should be sent to the server.
## Why are we removing the use of `SSL_CTX_set_client_CA_list` by
default for the TLS server credentials?
Removing the use of this API by default has 2 benefits:
1. Calling this API makes gRPC TLS unusable for servers with a
sufficiently large trust bundle. Indeed, if the server trust bundle is
too large, then the server will always fail to build the ServerHello.
2. Calling this API is introducing a huge amount of overhead (1000s of
bytes) to each ServerHello, so removing this feature will improve
connection establishment latency for all users of the TLS server
credentials.
Add -weak_framework CoreFoundation to the ruby extension link line on
arm64-darwin, to address "undefined symbols" issues from #33483
This is a variation on #33513 in response to feedback and so I've made
sure @alto-ruby is credited as co-author.

The function grpc_rb_call_run_batch has many places that could raise
errors, including in child functions. Since a raised error will longjump
out of the function, it will cause memory leaks since the function
cannot perform any clean up. This commit fixes the issue by wrapping the
whole function in an rb_ensure, which will ensure that a cleanup
function is ran before the error is propagated upwards.

re2 previously failed to compile if:
1. An old `re2` version is installed with a non-standard system prefix,
such as `/opt/local`.
2. The environment variable is set: `CPPFLAGS=-I/opt/local/include`.
Running `make` would result in function prototype mismatches because the
Makefile would previously attempt to use the headers from
`/opt/local/include/re2` before the `third_party/re2/re2` directory.
https://github.com/grpc/grpc/pull/27660 caused `CPPFLAGS` to inherit
from the environment, but this can cause the Makefile to use external
include files for re2 and other libraries if `-I` flags are defined.
This commit reverts to the original behavior of only using
`RbConfig::CONFIG` values to avoid using the wrong headers.
Let's see if this fixes the "Bus error" flakes that have been happening
in CI.
If it does, then we can narrow things down a bit. If flakes continue,
then we can revert this PR.
* src/proto/grpc/core/stats.proto no longer exists
* remove PHP generated file for proto that no longer exists
