We don't want other APIs to copy the stub-based API to attach the
interceptor. The API has a shorter name, but isn't actually all that
easier to use and isn't fluent like using the interceptor API.
These are _very_ old methods, so we won't be quick to delete them. Seems
we should have them deprecated at least a year or two; they are easy to
maintain in the mean time.
See API Review notes in #1789
Rebased PR #8343 into the first commit of this PR, then (the 2nd commit) reverted the part for metric recording of retry attempts. The PR as a whole is mechanical refactoring. No behavior change (except that some of the old code path when tracer is created is moved into the new method `streamCreated()`).
The API change is documented in go/grpc-stats-api-change-for-retry-java
The unit tests in RetriableStreamTest do not really test buffer limit from end to end, because the buffer limit is implemented using ClientStreamTracer.Factory, and the tracer callback outboundMessageSize() is only triggered in AbstractClientStream after message serialization. In fact, it was broken without failing any existing tests (#8343 (comment))
This PR adds a retry buffer limit test that runs through the AbstractClientStream code path.

Previously, rpc-behavior values in the request headers are handled in tow different places, one in interceptor and the other in service implementation via Context. I moved all the rpc-behavior handling in interceptor, Context is not needed any more.
This can be used by annotation processors to avoid processing the
gRPC-generated code. The normal Generated annotation only has SOURCE
retention, so isn't available to annotation processors.
I don't include the service name within the annotation as that assumes
we'll never have need for any other type of generated class. If there's
a request for exposing service name via an annotation in the future, we
can make an RpcService annotation or the like.
Fixes#8158
Because we are emulating aarch64 during testing the tests run slower
than normal. Bumping the timeout seems easy and obvious for
StressTestClientTest. The warmup for BinlogHelperTest mirrors what we've
done with timing-based tests in the past. Hopefully that is enough to
lower variance so that it passes consistently; seems likely. I'd rather
not increase the timing fuzziness if I can avoid it, as that reduces the
test's ability to detect issues.
Fixes#8135 (mostly+hopefully)
failOnVersionConflict has never been good for us. It is equivalent to
Maven dependencyConvergence which we discourage our users to use because
it is too tempermental and _creates_ version skew issues over time.
However, we had no real alternative for determining if our deps would be
misinterpeted by Maven.
failOnVersionConflict has been a constant drain and makes it really hard
to do seemingly-trivial upgrades. As evidenced by protobuf/build.gradle
in this change, it also caused _us_ to introduce a version downgrade.
This introduces our own custom requireUpperBoundDeps implementation so
that we can get back to simple dependency upgrades _and_ increase our
confidence in a consistent dependency tree.
To separately manage services/classes with and without protobuf dependency in services package, we are moving classes with protobuf dependency into io.grpc.protobuf.services. This includes healthchecking, reflection, channelz, and binlogging.
Forwarding classes are created to avoid breaking existing users, while they are marked as deprecated to notify users to migrate.
Updates TestServiceClient to support creating channel without target port (mostly useful for xDS that uses the channel target as the resource name).
Adds an env var for overriding the TD URI used in cloud-to-prod test.
Starting in Netty 4.1.60, Netty will validate Content-Length headers
using getAll() and setLong(). While getAll() was documented as only used
in tests, it doesn't appear it was currently used in any tests.
While Http2NettyTest.contentLengthPermitted() was added to confirm that
Content-Length works, it won't actually exercise any interesting
behavior until we upgrade to Netty 4.1.60. However, I did test with
Netty 4.1.60 and it reproduced the failure in
https://github.com/grpc/grpc-java/issues/7953 and passed with this
change.
Since Netty is now observing/modifying the headers, it would seem
appropriate to implement a substantial portion of the Http2Headers API.
However, the surface is much larger than we'd want to implement for a
'quick fix' that could be backported. In addition, it seems much of the
API is just convenience methods, so it is probably appropriate to split
out a AbstractHeaders class from DefaultHeaders in Netty that doesn't
make any assumptions about the header storage mechanism.
Changes the xDS interop test client to support timeout test.
- Synced xDS test proto messages with grpc-proto.
- Changed RpcConfig to be the configuration for per test method type. Added timeoutSec for its deadline configuration.
- Changed accumulated stats to include RPC status instead of just succeeded/failed.
Resolves#7741
Some of the static methods in generated code have the same method name but different package name, such `ClientCalls.asyncClientStreamingCall` and `ServerCalls.asyncClientStreamingCall`. It's less readable using static import than using full-qualified method name in-place.
The proto field is named as num_failures but its comment is saying it is for number of RPCs that failed to record a remote peer. RPC failed == RPC failed to record a remote peer was true previously (so no existing tests should be affected by this changed) as server completed RPCs immediately. It is no longer true with server capability to keep the call open/delayed.
This change clarifies the proto definition for stats RPC. rpcs_by_peer is for recording RPCs succeeded and num_failures is for RPCs failed. RPCs in the flight when the stats call times out are not counted towards any of the stats.
Update xDS interop test proto to aggregate accumulated stats based on RPC methods (mirroring 643e5bcd1e8db931cf76a3be19cd9bba223ee987 in C-core's change). Updated the xDS interop test client to support querying accumulated stats aggregated to RPC methods.
The main() Thread will call tearDown() itself. It appears this
redundancy has existed since e813eaae2f, where the normal error handling
was enhanced at the same time as cleaning up resource management. The
cleanup should have made it obvious the hook was no longer needed, but
alas. Technically, it did originally provide a purpose if setup()
failed, but it would have been better to just move setup() into the
try-catch instead. Today it doesn't even provide that purpose.
Most of these are easy "replace X with Y."
The CreateStartScripts changes were because the scripts were being included in
the output zip/tar multiple times. The was because they were all using the same
output directory, and the entire output directory was being included for each.
The output directory tmp/ was particularly poor because other tasks were
dumping things into it, so our zip/tar was including those junk files as well.
This prevents grpc-xds and its transitive dependencies from being included
twice in distTar and distZip, which reduces the size from 60 MB to 40 MB. It
does mean that interop-testing as a whole depends on xds, but that should not
be an issue any longer. It was an issue before we started providing grpc-xds on
Maven Central.
