Proposed alternative to https://github.com/grpc/grpc/pull/34024.
This version has a simpler, faster busy-count implementation based on a
sharded set of atomic counts: fast increment/decrement operations,
relatively slower summation of total counts (which need to happen much
less frequently).
- Extract build metadata for some external dependencies from bazel
build. This is achieved by letting extract_metadata_from_bazel_xml.py
analyze some external libraries and sources. The logic is basically the
same as for internal libraries, I only needed to teach
extract_metadata_from_bazel_xml.py which external libraries it is
allowed to analyze.
* currently, the list of source files is automatically determined for
`z`, `upb`, `re2` and `gtest` dependencies (at least for the case where
we're building in "embedded" mode - e.g. mostly native extensions for
python, php, ruby etc. - cmake has the ability to replace some of these
dependencies by actual cmake dependency.)
- Eliminate the need for manually written gen_build_yaml.py for some
dependencies.
- Make the info on target dependencies in build_autogenerated.yaml more
accurate and complete. Until now, there were some depdendencies that
were allowed to show up in build_autogenerated.yaml and some that were
being skipped. This made generating the CMakeLists.txt and Makefile
quite confusing (since some dependencies are being explicitly mentioned
and some had to be assumed by the build system).
- Overhaul the Makefile
* the Makefile is currently only used internally (e.g. for ruby and PHP
builds)
* until now, the makefile wasn't really using the info about which
targets depend on what libraries, but it was effectively hardcoding the
depedendency data (by magically "knowing" what is the list of all the
stuff that e.g. "grpc" depends on).
* After the overhaul, the Makefile.template now actually looks at the
library dependencies and uses them when generating the makefile. This
gives a more correct and easier to maintain makefile.
* since csharp is no longer on the master branch, remove all mentions of
"csharp" targets in the Makefile.
Other notable changes:
- make extract_metadata_from_bazel_xml.py capable of resolving workspace
bind() rules (so that it knows the real name of the target that is
referred to as e.g. `//external:xyz`)
TODO:
- [DONE] ~~pkgconfig C++ distribtest~~
- [DONE} ~~update third_party/README to reflect changes in how some deps
get updated now.~~
Planned followups:
- cleanup naming of some targets in build metadata and buildsystem
templates: libssl vs boringssl, ares vs cares etc.
- further cleanup of Makefile
- further cleanup of CMakeLists.txt
- remote the need from manually hardcoding extra metadata for targets in
build_autogenerated.yaml. Either add logic that determines the
properties of targets automatically, or use metadata from bazel BUILD.

Intercepted call class expect a timeout as parameters but a deadline is
provided instead. Only the UnaryUnary class is correctly created with a
timeout while the others remains with the deadlines. This commit fix the

Implement DNS using dns service for iOS.
Current limitation:
1. Using a custom name server is not supported.
2. Only supports `LookupHostname`. `LookupSRV` and `LookupTXT` are not
implemented.
3. Not tested with single stack (ipv4 or ipv6) environment
4. ~Not tested with multiple ip records per stack~ manually tested with
wsj.com
5. Not tested with multiple interface environment
Refactored OpenCensus context propagation flow, now propagation happens
for each call and context will be automatically propagated from gRPC
server to gRPC client.
We're using `execution_context` in OpenCensus since the context is
related to OpenCensus and it helps wrap `contextVar` for us.
### Testing
* Added a new Bazel test case for context propagation.

.
This change adds `__reduce__` to `AioRpcError` to allow pickle.
### Testing
Added bazel unit test, without this change, test will fail with error:
```
TypeError: AioRpcError.__init__() missing 3 required positional arguments: 'code', 'initial_metadata', and 'trailing_metadata'
```
Why: Cleanup for chttp2_transport ahead of promise conversion - lots of
logic has become interleaved throughout chttp2, so some effort to
isolate logic out is warranted ahead of that conversion.
What: Split configuration and policy tracking for each of ping rate
throttling and abuse detection into their own modules. Add tests for
them.
Incidentally: Split channel args into their own header so that we can
split the policy stuff into separate build targets.

This PR:
- Fixes the xds-protos Python package, which was broken when the `udpa`
submodule was removed
- This required re-adding the protoc-gen-validate submodule
- Adds non-Bazel tests for xds-protos and all of its dependent packages
- Versions xds-protos the same way as the rest of the Python packages
- Fixes Python 3.11 support in `run_tests.py`, which is necessary for
the testing mentioned above
CC @sergiitk You won't be able to consume this in the interop tests
until it makes it into a release. I'm thinking I'll want to backport
this to the 1.57.x branch to make that happen faster.
CC @drfloob to inform him about the likely backport.
This PR implements a c-ares based DNS resolver for EventEngine with the
reference from the original
[grpc_ares_wrapper.h](../blob/master/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.h).
The PosixEventEngine DNSResolver is implemented on top of that. Tests
which use the client channel resolver API
([resolver.h](../blob/master/src/core/lib/resolver/resolver.h#L54)) are
ported, namely the
[resolver_component_test.cc](../blob/master/test/cpp/naming/resolver_component_test.cc)
and the
[cancel_ares_query_test.cc](../blob/master/test/cpp/naming/cancel_ares_query_test.cc).
The WindowsEventEngine DNSResolver will use the same EventEngine's
grpc_ares_wrapper and will be worked on next.
The
[resolve_address_test.cc](https://github.com/grpc/grpc/blob/master/test/core/iomgr/resolve_address_test.cc)
which uses the iomgr
[DNSResolver](../blob/master/src/core/lib/iomgr/resolve_address.h#L44)
API has been ported to EventEngine's dns_test.cc. That leaves only 2
tests which use iomgr's API, notably the
[dns_resolver_cooldown_test.cc](../blob/master/test/core/client_channel/resolvers/dns_resolver_cooldown_test.cc)
and the
[goaway_server_test.cc](../blob/master/test/core/end2end/goaway_server_test.cc)
which probably need to be restructured to use EventEngine DNSResolver
(for one thing they override the original grpc_ares_wrapper's free
functions). I will try to tackle these in the next step.

In preparation for implementing the promise based version, separate out
the legacy call data from the filter.
There are two commits here, each representing one phase of this code
movement:
66676d398c moves `class RetryFilter` into
the header and the vtable name into that class, as this will be shared
code between the implementations
4c84f115ad then moves `class
RetryFilter::CallData` into `class RetryFilterLegacyCallData`, and moves
*that* into its own file
Doing so makes me less confused as to what I'm editing going forward.
No functionality should be affected.

More work on the dualstack backend design:
- Change round_robin to delegate to pick_first instead of creating
subchannels directly.
- Change pick_first such that when it is the child of a petiole policy,
it will unconditionally start a health watch.
- Change the client-side health checking code such that if client-side
health checking is not enabled, it will return the subchannel's raw
connectivity state.
- As part of this, we introduce a new endpoint_list library to be used
by petiole policies, which is intended to replace the existing
subchannel_list library. The only policy that will still directly
interact with subchannels is pick_first, so the relevant parts of the
subchannel_list functionality have been copied directly into that
policy. The subchannel_list library will be removed after all petiole
policies are updated to delegate to pick_first.
The address attribute interface was intended to provide a mechanism to
pass attributes separately from channel args, for values that do not
affect subchannel behavior and therefore do not need to be present in
the subchannel key, which does include channel args. However, the
mechanism as currently designed is fairly clunky and is probably not the
direction we will want to go in the long term.
Eventually, we will want some mechanism for registering channel args,
which would provide a cleaner way to indicate that a given channel arg
should not be used in the subchannel key, so that we don't need a
completely different mechanism. For now, this PR is just doing an
interim step, which is to establish a special channel arg key prefix to
indicate that an arg is not needed in the subchannel key.
With some delay, this is a PR for
https://github.com/grpc/grpc/issues/32564 (and previously
https://github.com/grpc/grpc/pull/31791).
I looked into adding a regular `py_test` for this change [as
suggested](https://github.com/grpc/grpc/pull/31791#issuecomment-1423245116)
but I am not aware of any effect that the presence of a .pyi stub file
would have at runtime and where some sort of type-checking in a .py
script would be affected. Stub files are only for use by type checkers &
IDE's. I mean, something like this would work:
```
import helloworld_pb2
py_file = helloworld_pb2.__file__
pyi_file = py_file + 'i’
self.assertTrue(os.path.exists(pyi_file))
```
But that seems really hacky to me. Instead I created a simple rule test
for `py_proto_library` with Bazel Skylib which tests the declared
outputs for an example `py_proto_library` target. Indirectly, this also
tests that the declared output files are actually generated. Please let
me know if this is sufficient.
- Switched from yapf to black
- Reconfigure isort for black
- Resolve black/pylint idiosyncrasies
Note: I used `--experimental-string-processing` because black was
producing "implicit string concatenation", similar to what described
here: https://github.com/psf/black/issues/1837. While currently this
feature is experimental, it will be enabled by default:
https://github.com/psf/black/issues/2188. After running black with the
new string processing so that the generated code merges these `"hello" "
world"` strings concatenations, then I removed
`--experimental-string-processing` for stability, and regenerated the
code again.
To the reviewer: don't even try to open "Files Changed" tab 😄 It's
better to review commit-by-commit, and ignore `run black and isort`.

This is a hack to get around an issue on Apple devices caused by the
PosixEventEngine's `poll` poller not supporting fork. This PR disables
the EventEngine poller entirely in Python builds. It will therefore
prevent the release of the EventEngine generally, and prevent any
testing of EventEngine integration with gRPC Python, until the `poll`
poller is fixed.

The VSOCK address family facilitates communication between
virtual machines and the host they are running on.
This patch will introduce new scheme: [vsock:cid:port] to
support VSOCK address family.
Fixes#32738
Most of these data structures need to scale a bit like per-cpu, but not
entirely. We can have more than one cpu hit the same instance in most
cases, and probably want to cap out before the hundreds of shards some
platforms have.

The internal test is failing because after the change, transitive
dependencies will be included in response too, thus we need add
`empty2_pb2` to response since it's a dependency of
`empty2_extensions_pb2`.
We already did that in OSS test, we need do the same for internal test
case.
The logger uses `absl::FPrintF` to write to stdout. After reading a
number of sources online, I got the impression that `std::fwrite` which
is used by `absl::FPrintF` is atomic so there is no locking required
here.
