This code is not compiled by default and has fallen out of sync with the
rest of the codebase. There's a good chance it won't be used, given our
current work to use an iomgr-drive EventEngine instead.
This code will continue to live in git history, should we need to bring
pieces of it back.

We've had a post init function on channel stack builder for a very long
time, an it serves to run some code after initialization completes.
We need the functionality for a few things, but the function passed in
is intimately tied to the filter in use - we never vary it between
multiple functions for the same filter... which means it makes more
sense to locate this functionality as part of the filter interface.

priority:
- go back to starting failover timer upon CONNECTING, but only if seen
READY or IDLE more recently than TRANSIENT_FAILURE
ring_hash:
- don't flap back and forth between IDLE and CONNECTING; once we go
CONNECTING, we stay there until either TF or READY
- after the first subchannel goes TF, we proactively start another
subchannel connecting, just like we do after a second subchannel
reports TF, to ensure that we don't stay in CONNECTING indefinitely if
we aren't getting any new picks
- always return ring hash's picker, regardless of connectivity state
- update the subchannel connectivity state seen by the picker upon
subchannel list creation
- start proactive subchannel connection attempt upon subchannel list
creation if needed

* Fixes a flake with the LoadReporter end2end test.
I *believe* the test is wrong, based on the .proto description of the
LoadReporter.
The protocol described in src/proto/grpc/lb/v1/load_reporter.proto has
the ReportLoad rpc returns a stream of LoadReportResponse, which itself
has a repeated field of Load messages. The comment before it states:
"It is not strictly necessary to aggregate all entries into one entry
per <tag, user_id> tuple, although it is preferred to do so."
Debugging the issue shows we are in fact properly getting all 3 expected
load report types, just in two separate messages instead of a single
one.
This new test codepath will coalesce the load report responses, and also
addresses the fact the original test wasn't verifying that we were
getting the 3 expected types.

Based on a handful of https://abseil.io/tips, it's generally advised to
only fully-qualify namespaces when in a `using` statement, or when it's
otherwise required for compilation. In all other cases, the general
recommendation is to not fully-qualify.
This change fixes most `grpc.*` namespace uses. There are potential
challenges in trying to make blanket changes to non-gRPC namespace uses,
such as `::testing`, since there is also a `grpc::testing` namespace.

* [issue #28771] Fix pick_first policy to clear selected_ when promoting
a pending subchannel list to the active subchannel list when all
subchannels have been attempted and are in an error state.
* address comments
* revert idle_filter
Instead of passing transport optionally as an argument adjacent to channel args, pass it as a channel arg directly.
Doing so does not affect semantics, but does allow a cleaner API for channel creation which will become increasingly important as we move towards promises.

* Upgrade benchmark to 1.6.0 and remove hacks.
Details:
- GRPC currently uses an old version of benchmark (from Sept 2020). It should probably upgrade because downstream, in google3, everyone is already using 1.6.0)
- Removed the hack added in PR/27629 to allow benchmarks in GRPC to continue to work with both pre-1.6.0 and 1.6.0 benchmarks.
(This was needed to allow importing benchmarks 1.6.0 into google3 without breaking GRPC)

Backports sourcing the test driver install script from master.
This is a backport of #27389, #27462 and #27658:
* Add missing quatation marks.
These were missed when creating the Python virtual env.
* xds-k8s tests: Use test driver from master branch (#27462)
Instead of directly sourcing the test driver provisioning script from the same branch, the script is downloaded (with curl) and sourced from the master branch.
This allows changes made to the test driver to be reflected in all future release branches. A separate PR will backport this change to existing release branches.

It used to be that we could run the hpack deserializer into an arbitrary
sink - that's about to change and the hpack deserializer will buffer
directly into a map. That being the case, it's really hard to compare
performance of the current and the new system. With this PR, I'm
updating the relevant scenario to be more similar to the eventual
scenario that we plan, so that as the new work finishes up, we can get a
clearer idea of what changes we're really making.
* Make generated code compile with -Wunused-parameters
-Wunused-parameters is turned on by -Werror -Wextra. gRPC code
generation creates header files with unused parameters. So let's modify
the generator to not generate code which will make -Wunused-parameters
unhappy.
* Fix unsigned vs signed comparisons and 32 bit string formats
Fix unsigned vs signed comparison warnings.
For 64 bit numbers printed in gRPC, the string formats assume that you
are running on a 64 bit machine. Use inttypes.h to make it portable.
Also, use size_t format strings for the same reason.
* Fix unaligned memory access
cost_entry_ptr has no alignment guarentees that ubsan can find. So it
fails the test with an alignment problem. Use memcopy to read the data
from the pointer to fix this.
* Fix undefined behavior with memcpy and memcmp
Passing in a 0 length piece of data and a null pointer is undefined
behavior. If the length is 0, don't pass it in. This fixes ubsan
failures.
* Clang-format
* Automated change: Fix sanity tests
* Fix OOM issues in qps tests
* Add more verbose logging.
* Fix clang error
* Fix race between IsCancelled and Read
* Fix build errors from using bool in C code
* Ensure that per route retry policy (even when there are no supported
retry_on statuses) still takes precedence over virtual host level retry
policy.
Added a test to guard this case.
* Taking care of code review comments and removing unnecessary block
* xDS Security: Use new way to fetch certificate provider plugin instance
config
* Reviewer comments
* Additional fields to NACK
* Move NACKing tests for tls_certificates and tls_certificate_sds_securet_configs to client-side
* fix retry code to fail batches instead of creating attempt if previously cancelled from surface
* add xDS end2end tests covering the FI use-case that triggered the bug
* fix memory leak
If we continue to call `Write()` after `WriteLast()` (because client is still sending us data and thus `Read()` returns `true`), the buffer might become invalid and results in assertion failures.
This temporarily unblocks a related gtest upgrade. The ultimate goal is
to upgraade our gtest dependencies, but I don't have the cycles to
manage a potentially messy migration until at least next week. This PR
is coordinated with an internal change.
See code commentary for an explanation.
Add an additional constructor to allow `log_linux.cc` to compile with
GPR_PTHREAD_TLS. Without it:
```
../../third_party/grpc/src/core/lib/gpr/log_linux.cc:78:33: error: no viable conversion from 'int' to 'grpc_core::PthreadTlsImpl<long>'
static GPR_THREAD_LOCAL(long) tid = 0;
^ ~
../../third_party/grpc/src/core/lib/gpr/tls.h:64:3: note: candidate constructor not viable: no known conversion from 'int' to 'const grpc_core::PthreadTlsImpl<long> &' for 1st argument
PthreadTlsImpl(const PthreadTlsImpl&) = delete;
^
1 error generated.
```
* Implement type safety for TLS
This is mostly free when compiler support is available, but requires
careful templating when implemented using pthread.
Significantly slimmed the tls.h interface; it now only defines the "TLS
keyword" for each supported compiler, delegating enforcement of correct
usage (i.e. must be static) to the compiler itself.
Implemented implicit conversion for the pthread wrapper so it can be
used (mostly) the same as native support. Notable exception to this is
that static_cast<void*> is needed when printing a pointer stored in TLS
as %p.
* Use GPR_THREAD_LOCAL macros consistently
* Buffer HPACK parsing until the end of a header boundary
HTTP2 headers are sent in (potentially) many frames, but all must be
sent sequentially with no traffic intervening.
This was not clear when I wrote the HPACK parser, and still indeed quite
contentious on the HTTP2 mailing lists.
Now that matter is well settled (years ago!) take advantage of the fact
by delaying parsing until all bytes are available.
A future change will leverage this to avoid having to store and verify
partial parse state, completely eliminating indirect calls within the
parser.

This exposes a bug in clang, reported upstream as
https://bugs.llvm.org/show_bug.cgi?id=51368.
The clang bug is mitigated using a fake scoped lock; that allows the
current code to compile while also serving as a change detector to
prevent it from going stale; if the compiler bug is fixed, the compiler
will see an overlapping locking requirement, and reject this code, which
will prompt a human being to remove this workaround.
It is not possible for such a function to be implemented in a way that
is understood by annotalysis. Mark it deprecated and replace instances
of its use with direct mutex/condvar usage.
Add a bunch of missing thread safety annotations while I'm here.

This is a fairly low effort migration of the current codebase into a C++ class, instead of free standing C code.
It builds upon #26657 as a necessary first step.
I've tried to minimize any changes to semantics or logic in this change, except where required to get a minimal amount of encapsulation - which is the major aim of this change.
A future change in this series will buffer slices until all HPACK headers are in memory for a stream prior to decoding -- it's important to have an encapsulated API to the parser before doing so however (hence this CL).
The next change after that will be an almost complete rewrite of the parsing functionality -- since we'll have the total set of header bytes, we'll no longer need to support suspending decoding at arbitrary points. This will allow us to move to a simple recursive descent parser, eliminate a bunch of indirection in this code, and end up in a much more malleable place for when we start doing metadata API changes.
(we likely also end up with some good performance wins!)

This code adds an iomgr implementation that's backed by an EventEngine. This uses the EventEngine API alone, and separate work will introduce an EventEngine prototype to plug into it.
See also drfloob#1: @nicolasnoble has a pull request against this branch, implementing the libuv-based EventEngine. One goal here is to implement the iomgr code such that it can be merged independently without affecting normal builds.
This implementation can be built using bazel build --cxxopt='-DGRPC_USE_EVENT_ENGINE' :all
Some shortcuts are being taken to get a working, testable version of the engine. EventEngines are not pluggable, for example.

* xds_end2end_test: avoid flakes from lingering shutdown from previous test
The urgent argument is a platform-specific flag that leaked into the (ideally) platform-independent HTTP/2 transport layer. In an effort to clean up the cross-platform API surface, it would be helpful if we can remove this argument from the TCP Read api without losing the performance optimization that was introduced along with it (see #18240).
Interop reported an error for a present match and it is discovered this
case is missing from unit test. We have test for present (false) and we
have special case test but we don't have the normal present (true) test.
We also had a bug in a our code:
if (!value.has_value()) {
if (header_matcher.type ==
XdsApi::Route::Matchers::HeaderMatcher::HeaderMatcherType::PRESENT) {
return !header_matcher.present_match;
} else {
// For all other header matcher types, we need the header value to
// exist to consider matches.
return false;
}
}
switch (header_matcher.type) {
case XdsApi::Route::Matchers::HeaderMatcher::HeaderMatcherType::EXACT:
return value.value() == header_matcher.string_matcher;
case XdsApi::Route::Matchers::HeaderMatcher::HeaderMatcherType::REGEX:
return RE2::FullMatch(value.value().data(), *header_matcher.regex_match);
case XdsApi::Route::Matchers::HeaderMatcher::HeaderMatcherType::RANGE:
int64_t int_value;
if (!absl::SimpleAtoi(value.value(), &int_value)) {
return false;
}
return int_value >= header_matcher.range_start &&
int_value < header_matcher.range_end;
case XdsApi::Route::Matchers::HeaderMatcher::HeaderMatcherType::PREFIX:
return absl::StartsWith(value.value(), header_matcher.string_matcher);
case XdsApi::Route::Matchers::HeaderMatcher::HeaderMatcherType::SUFFIX:
return absl::EndsWith(value.value(), header_matcher.string_matcher);
default:
return false;
}
Note if header has value, we will go into the swtich but there is no case
XdsApi::Route::Matchers::HeaderMatcher::HeaderMatcherType::PRESENT,
which means we would have gone into default and decleared not a match.
The same day this bug was discovered by interop test, https://github.com/grpc/grpc/pull/25122
was submitted and the refactoring fixed the bug.
Nevertheless, I added the test case for the future.
was not the correct fix and caused window test issues.
The correct fix is to ensure the test uses the same time apis as the
product code: grp_get_cycle_counter (which is platform dependent) to get
current time.
Tested both in open source and patched into google3 to ensure successful
import:

Google's internal version of the gRPC codebase uses a version of
protobuf with a different namespace and include paths. This commit makes
parse_json.cc rely on config_protobuf.h for protobuf types so that it
will work properly in that environment. I also replaced a call to
Status::error_code() with a call to Status::code() instead. This way the
code will work with absl::Status, which has a somewhat different API
compared to google::protobuf::util::Status.
Code used absl::string_view to point into FLAG_xxx, when we changed
to uses absl::GetFlag, absl::string_view is pointing into temp variables
which results in undefined behaviour for the flags.
This replaces gflags. Added TODOs where use of `absl::Duration` or `absl::FlagSaver` might be preferred in follow-up cleanup. Fixes#24493.
This reverts commit da66b7d14e.
NEW:
* Adds references to `absl/flags/declare.h`, new to LTS 2020923.2 imported in commit 5b43440.
* Works around MSVC 2017 compiler error with large help text on flags by reducing the help text.

It is observed that ADS is shutdown, but it's possible that

This request should not update the ADS resource_type_response_state_ as
they were cleared by the shutdown.
This fix ensures this.
