These tests are for the new HTTP/2 test server (grpc/grpc#8900). They are designed to test client behavior when the server sends unexpected responses during rpcs.
GrpcServerRule configures an in-process server and channel. It is
useful for asserting requests being made to a service. A consumer can
create a mock implementation of their service that records each
request, then make assertions on those records in their test.
* interop-testing: modify the stress test client to accept the same --use_tls, --use_test_ca, and --server_host_override arguments as the interop client.
Clarify usage of --use_test_ca=true for stress and interop clients.
Resolves#1936
Two bugs fixed:
- NPE in `ServerImpl#streamCreated()` when stream listener not set before
stream closed
- It is possible that `internalCancel()` is called during
`InProcessClientStream#start()` due to early server `onComplete()` or server `onError()`,
in this case no need to enlist `streams`, otherwise the channel can not be shutdown by `shutdown()`.
core: adds @Nullable Object getAttachedObject() to ServiceDescriptor
compiler: Plumbing necessary to access proto file descriptors via
the reflection service
This prevents an assertion in the cross-language interop test suite:
Exception in thread "main" java.lang.AssertionError: No record found

Highlights
==========
StatsTraceContext
-----------------
The bridge between gRPC library and Census. It keeps track of the total
payload sizes and the elapsed time of a Call. The rest of the gRPC code
doesn't invoke Census directly.
Context propagation
-------------------
StatsTraceContext carries CensusContext (and the upcoming TraceContext)
and is attached to the gRPC Context.
1. StatsTraceContext is created by ManagedChannelImpl, by calling
createClientContext(), which inherits the current CensusContext if available.
2. ManagedChannelImpl passes StatsTraceContext to ClientCallImpl, then
to the stream, then to the framer and deframer explicitly.
3. ClientCallImpl propagates the CensusContext to the headers.
1. ServerImpl creates a StatsTraceContext by implementing a new callback
method StatsTraceContext methodDetermined(MethodDescriptor, Metadata) on
ServerTransportListener.
2. NettyServerHandler calls methodDetermined() before creating the
stream, and passes the StatsTraceContext to the stream.
3. When ServerImpl creates the gRPC Context for the new ServerCall, it
calls the new method statsTraceContext() on ServerStream and puts the
StatsTraceContext in the Context.
Metrics recording
-----------------
1. Client-side start time: when ClientCallImpl is created
2. Server-side start time: when methodDetermined() is called
3. Server-side end time: in ServerStreamListener.closed(), but before
calling onComplete() or onCancel() on ServerCall.Listener.
4. Client-side end time: in ClientStreamListener.closed(), but before
calling onClonse() on ClientCall.Listener
Message sizes are recorded in MessageFramer and MessageDeframer. Both
the uncompressed and wire (possibly compressed) payload sizes are
counted.
TODOs
=====
The CensusContext created from headers on the server side should be
attached to the gRPC Context for the call. It's not done at this moment
because Census lacks the proper API to do it. It only affects tracing
and resource accounting, but doesn't affect stats functionality
Called whenever a ServerTransport is ready and terminated. Has the
ability to modify transport attributes, which ServerCall.attributes()
are based on.
Related changes:
- Attribute keys for remote address and SSL session are now moved from
ServerCall to a neutral place io.grpc.Grpc, because they can also be
used from ServerTransportFilter, and probably will be used on the
client-side too. The old keys on ServerCall is marked deprecated and
are equivalent to the new keys.
- Added transportReady() to ServerTransportListener.
Resolves#2132
After debugging #2153, it would have been nice to know what the exact
parameter was that was null. This change adds a name for each
checkNotNull (and tries to normalized on static imports in order to
shorten lines)
The value of nodeCount depended on deadlines expiring after the chain
was constructed. This is effectively the same as using Thread.sleep()
and would commonly fail if the machine was under load.
Instead of checking nodeCount after the deadline expires, we now wait
for the chain to be constructed and then cancel the RPC. This also
ensures that the cancel propagates instead of each hop just enforcing
the deadline. As a bonus, this also reduces test execution time by one
second. A new test was added for deadline propagation.
Fixes#1852
partially resolving #1469
The added option for java_plugin `enable_deprecated` is `true` by default in `java_plugin.cpp`, so the generated code for `TestService.java` (`compiler/build.gradle` not setting this option) has all deprecated interfaces and static bindService method.
`./build.gradle` and `examples/build.gradle` set this option explicitly to `false`, so all the other generated classes do not have deprecated code.
Will set `enable_deprecated` to `false` by default in future PR when we are ready.
conscrypt at some point which would allow ALPN to function
Clarify the SSLContext.getDefault is not used when constructing the
default SSLSocketFactory.
first step to address issue #1469:
- leave and deprecate interfaces in codegen
- introduce `ServiceImplBase`,
- `AbstractService` is deprecated and extends `ServiceImplBase`
- static `bindService()` is deprecated
Resolves#1756
The thread-unsafe method `io.grpc.testing.TestUtils.pickUnusedPort` causes flakes (#1756) in windows. Need to avoid use of this method in test as in windows the tests are running in different jvms and concurrent calls of this method in multiple processes tend to return the same port number.
There are some usages of this method in benchmarks, so moved the method to `io.grpc.benchmarks.Utils` and the method will only be used in benchmarks and not in test.
This allows us to play with zero-copy and proto3 support for lite.
Unfortunately, it introduced some warnings, so deprecated warnings are
now ignored for benchmarks and interop-testing.
This reverts commit 3df1446deb.
The commit was adding to the difficulty of integration for testing. By
itself it isn't bad, so this is a temporary revert until the many other
commits are absorbed and then it will be reapplied.
This does have a manual edit for ClientCallsTest.
It converts Google Auth Library Credentials to CallCredentials, and
supersedes ClientAuthInterceptor, which is now deprecated.
Also swaps out the ClientAuthInterceptor implementation.
Caveat: This in fact changes ClientAuthInterceptor's behavior. Before
this change, if multiple ClientAuthInterceptors were attached, their
effects would be additive. After this change, only the last executed one
would take effect, and it would also overwrite the CallCredentials set
in CallOptions. We don't think it's an issue, since other languages also
only allow one call credentials to be attached to an RPC.
This does not enable compression by default, but if the application
chooses to enable compression for a Call, messages will be compressed
without also needing to enable per-message compression.
Disabling per-message compression is intended as a security feature and
should be relatively rarely used, but it was the default. Thus we
required clients to use more advanced interfaces unnecessarily.
To keep client and server behavior consistent, the server also has
per-message compression enabled by default. However, to prevent
compressing on the wire by default, servers no longer enable compression
for the response by default.
This change updates the behavior of the core compression semantics. Previously,
if the codec was "identity", nothing was set on the wire. This is allowed by
the spec, but doesn't match what wrapped languages do.
Additionally, the interop tests will now attempt to honor the requested
compression.
Without the warm up I saw large deltas, like 2,262,968ns and
1,712,558ns, on my machine. With the single-line warm up the deltas
decreased dramitically, like 385ns and 536ns. Since our times are so
much better now, decreasing the required delta to 10ms seems reasonable.
This would seem to support the theory that the flakiness was caused by
the class loader, which may even be doing I/O.
Fixes#1646
This reverts commit 8825f355df.
The commit changed the package name of services that were used across
languages. That broke their functionality pretty severely. The changes
require more coordination with others.
As of the discussion in #1584, the client does not
support TLS and interop tests that require auth are
yet to be implemented.
It has the same functionality as the C++ stress test client.
A call's timeout as specified in its metadata should be set depending
on the deadline of the call's context. If a call has an explicit deadline
set (through CallOptions), then the smaller deadline (from context and call options)
should be used to compute the timeout.
Also, a new method Contexts.statusFromCancelled(Context) was introduced that attempts
to map a canceled context to a gRPC status.
- Made CallOptions use the Deadline type instead of a
long to represent a deadline.
- Added new methods CallOptions.withDeadline(Deadline) and
AbstractStub.withDeadline(Deadline). The methods are
marked experimental, as the Deadline class is marked
experimental. These methods are meant to replace
CallOptions.withDeadlineNanoTime(Long) and
AbstractStub.withDeadlineNanoTime(Long), which have
been deprecated.
- Updated CallOptions.toString() to include all fields.
There are two AbstractTransportTests. The newest one is the more aptly
named, so rename the older one to AbstractInteropTest to remove name
collision when speaking.
Fixes#1484
This reduces the necessary number of threads in the application executor
and provides a small improvement in latency (~15μs, which is normally in
the noise, but would be a 5% improvement).
Benchmark (direct) (transport) Mode Cnt Score Error Units
Before:
TransportBenchmark.unaryCall1024 true INPROCESS avgt 10 1566.168 ± 13.677 ns/op
TransportBenchmark.unaryCall1024 false INPROCESS avgt 10 35769.532 ± 2358.967 ns/op
After:
TransportBenchmark.unaryCall1024 true INPROCESS avgt 10 1813.778 ± 19.995 ns/op
TransportBenchmark.unaryCall1024 false INPROCESS avgt 10 18568.223 ± 1679.306 ns/op
The benchmark results are exactly what we would expect, assuming that
half of the benefit of direct is on server and half on client:
1566 + (35769 - 1566) / 2 = 18668 ns --vs-- 18568 ns
It is expected that direct=true would get worse, because
SerializingExecutor is now used instead of
SerializeReentrantCallsDirectExecutor plus the additional cost of
ThreadlessExecutor.
In the future we could try to detect the ThreadlessExecutor and ellide
Serializ*Executor completely (as is possible for any single-threaded
executor). We could also optimize the queue used in ThreadlessExecutor
to be single-producer, single-consumer. I don't expect to do those
optimizations soon, however.
When triggered, it caused the ClientCall.Listener never to complete.
Fixes#1343
The new test doesn't actually fail on my machine with the old code, but
we would hope it would be flaky. Since a race is involved, I don't
expect a more reliable test.
The client didn't have the trust manager set, so the RPC would fail due
to server-certificate verification, not lack of client auth.
With this change, noClientAuthFailure now fails with tcnative but still
passes with Jetty ALPN.
basicClientServerIntegrationTest seems to be working for me, so I'm
enabling it.
This reduces the number of classes defined, which reduces memory usage.
It also reduces the number of methods defined, which is important
because of the dex limit.
This should have virtually zero performance degradation because the
contiguous switch uses tableswitch bytecode.
This reverts commit eca1f7c1d6.
We want to preserve the status message identical to what the server
sent. We'll need a better way to communicate debugging details.
There is no need to use ServerMethodDefinition in codegen. The create()
method itself could be helpful to a dynamic HandlerRegistry
implementation, so we won't remove it.
Client:
* New ManagedChannel abstract class.
* Adding ping to Channel.
* Moving builders and implementations to internal.
Server:
* Added lifecycle management API to Server (mirroring ManagedChannel).
* Moved ServerImpl, AbstractServerBuilder and handler registries to internal.
* New ServerBuilder abstract class (mirroring ManagedChannelBuilder).
Fixes#545
Using a JWT is a bit more work than it should be, but improving that
will come later.
At present, this test fails, but it is believed to be due to the auth
library.
Reserve io.grpc for public API only, and all internal stuff in core to
io.grpc.internal, including the non-stable transport API.
Raise the netty/okhttp/inprocess subpackages one level up to io.grpc,
because they are public API and entry points for most users.
Details:
- Rename io.grpc.transport to io.grpc.internal;
- Move SharedResourceHolder and SerializingExecutor to io.grpc.internal
- Rename io.grpc.transport.{netty|okhttp|inprocess} to
io.grpc.{netty|okhttp|inprocess}
