This pulls in a patch that increases the max iteration limit, which is useful for extra-small microbenchmarks.
Closes#38163
PiperOrigin-RevId: 698524219
This is to unblock https://github.com/grpc/grpc/pull/38038 but gRPC needs to use one of released versions so later it should be updated once they release new one.
Closes#38140

- Adding two experiments for promises based HTTP2 transport.
- We have kept client and server transport experiments separate to help with smoother roll outs and also help with interop testing.
- The experiments are disabled, we expect this project to take several months.

We're about to completely change the wire format here... land one additional copy of the transport and tests as a hedge against bugs. Enable the hedge with an experiment.

Also remove a now-unnecessary dependency from the dump_args target that
previously had been needed just to get the right includes to be used.

Currently the destructive reclaimer single threaded cancels existing requests, but we admit new rpcs on every channel (to be eventually cancelled, probably).
We've got evidence that this (shockingly) doesn't scale and senders can easily overwhelm and oom a server.
Instead under this experiment now we'll always reject new work under very high load, and allow the reclaimer to mop up any remaining work to get back to within bounds.

Follow up from #37917 to add `noexcept` to multiple Cython functions using `nogil` with a `void` return type.
Below are the performance hints that were encountered as part of the Cython translation which are solved by this PR:
The below performance hint still exists, and is not resolved.
This is because `noexcept` expects that the function doesn't raise an exception, or a raised exception is just displayed as a warning and not propagated. But `_poll` raises an `AssertionError` at `QUEUE_TIMEOUT`, and hence cannot use `noexcept` with `_poll`.
As [PR 37917](https://github.com/grpc/grpc/pull/37917) and this PR now solves the Cython Asyncio test timeouts caused by Cython upgrade, this PR also reverts the Bazel Cython downgrade PR #37884
### Testing for timeout
Tested using `bazel test -c dbg --runs_per_test=3000 --test_timeout=10 "//examples/python/auth:_auth_example_test"`
```
//examples/python/auth:_auth_example_test PASSED in 4.6s
Stats over 3000 runs: max = 4.6s, min = 2.6s, avg = 3.2s, dev = 0.2s
```

To prepare for the upcoming upgrade to C++17, the following changes were made:
Increased minimum supported operating system versions:
- iOS: 11 (previously 10)
- macOS: 10.14 (previously 10.12)
- tvOS: 13.0 (previously 12.0)
In addition to this, version requirements across different projects were updated to use these for consistency.

This eliminates the need for the `grpc_cc_proto_library` bazel BUILD rule introduced in #37863.
To make this work, I had to upgrade several bazel dependencies and apply a patch to rules_go to work around https://github.com/bazelbuild/bazel/issues/11636.

This is a trial baloon to see if we can actually make this work. If it does, I'll change the remaining xDS tests to use the real xDS protos and completely remove our local copies.

We really should not have our own copy of these protos in the first
place, but there's some tech debt here that hasn't been cleaned up yet.
Until we do that, we should at least ensure that this tech debt doesn't
spread by having more code depend on them.

This was put in as a temporary kludge to carry us until `work_serializer_dispatch` was ready, however since #37637 this is a no-op for all known use cases (and I think it's time for `work_serializer_dispatch` to stick).

This PR adds templating for Python versions and updates the maximum supported Python version to 3.13. The following major changes related to templating are added:
- Minimum supported Python version and list of supported versions in `setup.py` are fetched using new template generated files called `python_version.py`
- Dockerfiles for the different Python Linux builds are now template generated.
- The "Supported Python Versions" section from READMEs of ancillary and main packages have been removed
Note: All the `python_version.py` files and Linux build `Dockerfiles` except `tools/dockerfile/grpc_artifact_python_linux_armv7/Dockerfile` in the PR are generated from the respective templates.
Further non-templated additions to add support for Python 3.13:
- install scripts and artifacts for windows, macos and linux are added manually. Later, these can be templated as well.
- updated cython bounds to 3.x
- updated twine version to solve [cgi module import error](https://github.com/pypa/twine/issues/1046)
- the twine update introduces a dependency on cryptography>=2.0. But the cryptography package doesn't support 32-bit Linux images and hence `twine check` has been disabled for x86 manylinux and x86 musllinux artifacts.
Closes#37643

This change adds an experiment to move time caching from `ExecCtx` (which is the wrong place for this mechanism) and moves it to the party update path (the expectation being that a single poll of a call is the granularity at which we expect time caching to be a useful optimization, whilst avoiding the unbounded hold times associated with the current mechanism).
This requires fixing up a few tests that grew to depend on time caching (would appreciate close eyes on the credentials test, as it's unclear to me why this is required or what the effect is).
This should also fix b/232544809.
