This bug occurred when the same xDS server was configured twice in the
same bootstrap config, once in an authority and again as the top-level
server. In that case, we were incorrectly failing to de-dup them and
were creating a separate channel for the LRS stream than the one that
already existed for the ADS stream. We fix this by canonicalizing the
server keys the same way in both cases.
As a separate follow-up item, I will work on trying to find a better way
to key these maps that does not suffer from this kind of fragility.
We shouldn't depend on how much the compression algorithm compresses the
bytes to. This is causing flakiness internally.

The very non-trivial upgrade of third_party/protobuf to 22.x
This PR strives to be as small as possible and many changes that were
compatible with protobuf 21.x and didn't have to be merged atomically
with the upgrade were already merged.
Due to the complexity of the upgrade, this PR wasn't created
automatically by a tool, but manually. Subsequent upgraded of
third_party/protobuf with our OSS release script should work again once
this change is merged.
This is best reviewed commit-by-commit, I tried to group changes in
logical areas.
Notable changes:
- the upgrade of third_party/protobuf submodule, the bazel protobuf
dependency itself
- upgrade of UPB dependency to 22.x (in the past, we used to always
upgrade upb to "main", but upb now has release branch as well). UPB
needs to be upgraded atomically with protobuf since there's a de-facto
circular dependency (new protobuf depends on new upb, which depends on
new protobuf for codegen).
- some protobuf and upb bazel rules are now aliases, so `
extract_metadata_from_bazel_xml.py` and `gen_upb_api_from_bazel_xml.py`
had to be modified to be able to follow aliases and reach the actual
aliased targets.
- some protobuf public headers were renamed, so especially
`src/compiler` needed to be updated to use the new headers.
- protobuf and upb now both depend on utf8_range project, so since we
bundle upb with grpc in some languages, we now have to bundle utf8_range
as well (hence changes in build for python, PHP, objC, cmake etc).
- protoc now depends on absl and utf8_range (previously protobuf had
absl dependency, but not for the codegen part), so python's
make_grpcio_tools.py required partial rewrite to be able to handle those
dependencies in the grpcio_tools build.
- many updates and fixes required for C++ distribtests (currently they
all pass, but we'll probably need to follow up, make protobuf's and
grpc's handling of dependencies more aligned and revisit the
distribtests)
- bunch of other changes mostly due to overhaul of protobuf's and upb's
internal build layout.
TODOs:
- [DONE] make sure IWYU and clang_tidy_code pass
- create a list of followups (e.g. work to reenable the few tests I had
to disable and to remove workaround I had to use)
- [DONE in cl/523706129] figure out problem(s) with internal import

This enables the EventEngine experiments in end2end tests, excluding the
ResourceQuota tests which have known failures.
Some Windows tests are hanging, so they will be enabled later.

If an engine is created, it should be fully functional regardless of
whether gRPC-core experiments are on or off. The trade-off for now is
that when the core experiments are not enabled, the engine will be
slowly polling with nothing to do.

Expand server promises to run with C++ end2end tests.
Across connected_channel/call/batch_builder/pipe/transport:
- fix a bug where read errors weren't propagated from transport to call
so that we can populate failed_before_recv_message for the c++ bindings
- ensure those errors are not, however, used to populate the returned
call status
Add a new latch call arg to lazily propagate the bound CQ for a server
call (and client call, but here it's used degenerately - it's always
populated). This allows server calls to be properly bound to
pollsets.(1)/(2)
In call.cc:
- move some profiling code from FilterStackCall to Call, and then use it
in PromiseBasedCall (this should be cleaned up with tracing work)
- implement GetServerAuthority
In server.cc:
- use an RAII pattern on `MatchResult` to avoid a bug whereby a tag
could be dropped if we cancel a request after it's been matched but
before it's published
- fix deadline export to ServerContext
In resource_quota_server.cc:
- fix some long standing flakes (that were finally obvious with the new
test code) - it's legal here to have client calls not arrive at the
server due to resource starvation, work through that (includes adding
expectations during a `Step` call, which required some small tweaks to
cq_verifier)
In the C++ end2end_test.cc:
- strengthen a flaky test so it passes consistently (it's likely we'll
revisit this with the fuzzing efforts to strengthen it into an actually
robust test)
(1) It's time to remove this concept
(2) Surprisingly the only test that *reliably* demonstrates this not
being done is time_change_test

This error can trigger for either initial or trailing metadata (and
we've had outages where the latter was the cause).
I don't think we know at this layer if we're parsing initial or trailing
- though it'd be a good exercise to plumb that through.
For now remove the word initial because it's better to give less
information than wrong information.

This reverts commit 4b46dbc19e.
Reason: this seems to be breaking load reports in certain cases,
b/276944116
Let's revert so this doesn't accidentally get released.
This PR aims to de-experimentalize the APIs for GCP Observability.
We would have ideally wanted public feedback before declaring the APIs
stable, but we need stable APIs for GA.
Changes made after API review with @markdroth@veblush, @ctiller and the
entire Core/C++ team -
* The old experimental APIs `grpc::experimental::GcpObservabilityInit`
and `grpc::experimental::GcpObservabilityClose` are now deprecated and
will be deleted after v.1.55 release.
* The new API gets rid of the Close method and follows the RAII idiom
with a single `grpc::GcpObservability::Init()` call that returns an
`GcpObservability` object, the lifetime of which controls when
observability data is flushed.
* The `GcpObservability` class could in the future add more methods. For
example, a debug method that shows the current configuration.
* Document that GcpObservability initialization and flushing (on
`GcpObservability` destruction) are blocking calls.
* Document that gRPC is still usable if GcpObservability initialization
failed. (Added a test to prove the same).
* Since we don't have a good way to flush stats and tracing with
OpenCensus, the examples required users to sleep for 25 seconds. This
sleep is now part of `GcpObservability` destruction.
Additional Implementation details -
* `GcpObservability::Init` is now marked with `GRPC_MUST_USE_RESULT` to
make sure that the results are used. We ideally want users to store it,
but this is better than nothing.
* Added a note on GCP Observability lifetime guarantees.

Notes:
- `+trace` fixtures haven't run since 2016, so they're disabled for now
(7ad2d0b463 (diff-780fce7267c34170c1d0ea15cc9f65a7f4b79fefe955d185c44e8b3251cf9e38R76))
- all current fixtures define `FEATURE_MASK_SUPPORTS_AUTHORITY_HEADER`
and hence `authority_not_supported` has not been run in years - deleted
- bad_hostname similarly hasn't been triggered in a long while, so
deleted
- load_reporting_hook has never been enabled, so deleted
(f23fb4cf31/test/core/end2end/generate_tests.bzl (L145-L148))
- filter_latency & filter_status_code rely on global variables and so
don't convert particularly cleanly - and their value seems marginal, so
deleted

This PR also centralizes the client channel resolver selection. Resolver
selection is still done using the plugin system, but when the Ares and
native client channel resolvers go away, we can consider bootstrapping
this differently.
This commit adds support for using CIDR blocks defined in the `no_proxy`
environment variable. For example:
```
http_proxy=http://localhost:8080 no_proxy=10.10.0.0/24
```
The example above would bypass the proxy if the server IP matched
10.10.0.0 - 10.10.0.255.
Closes#22681

The logic is straightforward: attempt to read the
`GRPC_ALTS_MAX_CONCURRENT_HANDSHAKES` environment variable and, if it
set to an integer, instantiate the handshake queues based on this
integer.
Based on go/grpc-alts-concurrent-handshake-cap.

Implement listeners, connection, endpoints for `FuzzingEventEngine`.
Allows the fuzzer to select write sizes and delays, connection delays,
and port assignments.
I made a few modifications to the test suite to admit this event engine
to pass the client & server tests:
1. the test factories return shared_ptr<> to admit us to return the same
event engine for both the oracle and the implementation - necessary
because FuzzingEventEngine forms a closed world of addresses & ports.
2. removed the WaitForSingleOwner calls - these seem unnecessary, and we
don't ask our users to do this - tested existing linux tests 1000x
across debug, asan, tsan with this change
Additionally, the event engine overrides the global port picker logic so
that port assignments are made by the fuzzer too.
This PR is a step along a longer journey, and has some outstanding
brethren PR's, and some follow-up work:
* #32603 will convert all the core e2e tests into a more malleable form
* we'll then use #32667 to turn all of these into fuzzers
* finally we'll integrate this into that work and turn all core e2e
tests into fuzzers over timer & callback reorderings and io
size/spacings

(hopefully last try)
Add new channel arg GRPC_ARG_ABSOLUTE_MAX_METADATA_SIZE as hard limit
for metadata. Change GRPC_ARG_MAX_METADATA_SIZE to be a soft limit.
Behavior is as follows:
Hard limit
(1) if hard limit is explicitly set, this will be used.
(2) if hard limit is not explicitly set, maximum of default and soft
limit * 1.25 (if soft limit is set) will be used.
Soft limit
(1) if soft limit is explicitly set, this will be used.
(2) if soft limit is not explicitly set, maximum of default and hard
limit * 0.8 (if hard limit is set) will be used.
Requests between soft and hard limit will be rejected randomly, requests
above hard limit will be rejected.

Previously we triggered a flow control update when `announced <
target/2`, but if `target==1` then we fail to send a flow control update
(announced is never less than 1/2==0) and break our forward progress
guarantees.
