Ciphers have been "fast enough" for testing since early Java 8 updates;
we haven't needed to override ciphers since we dropped Java 7 support.
Java 8u252 had ALPN, so Conscrypt or Jetty ALPN hasn't been necessary
for basic testing for a while. We still want specialized testing for
Conscrypt, but only tests testing Conscrypt need to care.
TlsTesting.loadCert() is a public API and so should be preferred over
our internal utility. It avoids creating a temp file that has to be
deleted by a shutdown hook. Usages that needed a file were not migrated.
%s is fairly safe (requires a Formattable to use Locale), so %d is the
main risk item. Places that really didn't need to use String.format()
were converted to plain string concatenation. Logging locations were
generally converted to using the log infrastructure's delayed
formatting, which is generally locale-sensitive but we're okay with
that. That wasn't done in okhttp, however, because Android frequently
doesn't use MessageFormat so we'd lose the parameters. Everywhere else
was explicitly defined to be Locale.US, to be consistent independent of
the default system locale.
This allows using GrpcCleanupRule with JUnit 5 when combined with
ExternalResourceSupport. We don't really lose anything important when
running with JUnit 4 and this eases migration to JUnit 5.
ExternalResource is now responsible for combining exceptions. after()
cannot throw checked exceptions, so we must now wrap the
InterruptedException. When used with JUnit 5 we are unable to detect the
test failed; we accept that for now but it may be fair to create a new
class for JUnit 5 to be used with `@RegisterExtension` that implements
BeforeEachCallback and AfterTestExecutionCallback to restore the JUnit 4
behavior.
See #5331
Fix an issue in GrpcCleanupRule when tests are retried and the
teardown() method is invoked multiple times, causing Stopwatch instance
to throw an IllegalStateException.

This allows io.grpc.testing.integration.Http2OkHttpTest to pass on ARM.
Currently Concrypt doesn't offer an ARM version of the native
components for OpenJDK, so running Http2OkHttpTest ends up with a
failure when ran on an ARM machine:
java.lang.UnsatisfiedLinkError: no conscrypt_openjdk_jni-linux-aarch_64 in java.library.path
Change InternalServer to handle multiple addresses and implemented in NettyServer.
It makes ServerImpl to have a single transport server, and this single transport server (NettyServer) will bind to all listening addresses during bootstrap. (#7674)
It deprecates ExpectedException and Assert.assertThat(T, org.hamcrest.Matcher).
Without Java 8 we don't want to migrate away from ExpectedException at
this time. We tend to prefer Truth over Hamcrest, so I swapped the one
instance of Assert.assertThat() to use Truth. With this change we get a
warning-less build with JUnit 4.13. We don't yet upgrade because we
still need to support JUnit 4.12 for some use-cases, but will be able to
upgrade to 4.13 soon when they upgrade.
Decouples grpc-core with census, while still preserve the default integration of census in grpc-core. Users wishing to enable census needs to add grpc-census to their runtime classpath.
- Created a grpc-census module:
- Moved CensusStatsModule.java and CensusTracingModule.java into grpc-census from grpc-core. CensusModuleTests.java is also moved. They now belong to io.grpc.census package.
Moved DeprecatedCensusConstants.java into io.grpc.census.internal (is this necessary?) in grpc-census.
- Created CensusStatsAccessor.java and CensusTracingAccessor.java, which are used to create census ClientInterceptor and ServerStreamTracer.Factory.
- Everything in grpc-census are package private, except the accessor classes. They only publicly expose ClientInterceptor and ServerStreamTracer.Factory, no Census specific types are exposed.
- Use runtime reflection to load and apply census stats/tracing to channel/server builders, if grpc-census is found in runtime classpath.
- Removed special APIs on AbstractManagedChannelImplBuilder and AbstractServerImplBuilder for overriding census module. They are only used for testing. Now we changed tests to apply Census ClientInterceptor and ServerStreamTracer.Factory just as normal interceptor/stream tracer factory. Test writer is responsible for taking care of the ordering concerns of interceptors and stream tracer factories.
We depend on Conscrypt to help ensure Conscrypt 2.1.0 or newer is used.
It's not 100% clear this is the best approach, but it is the simplest at
present. If Conscrypt is not available then we will just use the JDK's
slower implementation of AES-GCM.
Fixes#6213
The `method` and `status` shouldn't be propagated in the first place,
but in previous OpenCensus implementation all tags are propagating by
default. Now with the TagMetadata it may make sense to change them to
local tags.
This will be a breaking change to users who depend on the behavior that
these tags propagate through process boundaries.
Also updated CensusModule to use the new helper methods ContextUtils.withValue() instead of directly manipulating the context keys. See census-instrumentation/opencensus-java#1864.
This will be a new override. The old override is now deprecated.
In order to pass new information without adding new overrides, I shoved most information
into an object called StreamInfo. The Metadata is left out to draw attention because
it's mutable.
Motivation: this is needed for correctly supporting pick_first in GRPCLB. GRPCLB needs to
add a token to the headers, and the token varies among servers. With round_robin, GRPCLB
create a Subchannel for each server, thus can attach the token when the Subchannel is picked.
To implement pick_first, all server addresses will be put in a single Subchannel, we will
need to add the header in newClientStreamTracer(), by looking up the server address from
the transport attributes and deciding which token to add.
We've been on newer versions of Guava for a while now; these no longer
do anything.
Reworded the comment for Stopwatch.createUnstarted(), because it is not
safe (it doesn't matter if the method isn't marked Beta; you have to use
Ticker), except for the fact it is only used in our tests.
Following the [spec](https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md) on duplicate header names:
**Custom-Metadata** header order is not guaranteed to be preserved except for values with duplicate header names. Duplicate header names may have their values joined with "," as the delimiter and be considered semantically equivalent. Implementations must split Binary-Headers on "," before decoding the Base64-encoded values.
Returns a Channel that allows a LoadBalancer to make auxiliary RPCs on already-established application connections. We need this to implement client-side health-checking (#4932)
See comments on the API for its semantics.
Notable changes:
- Transports are modified to use InUseStateAggregator so that they can exclude RPCs made on Subchannel.asChannel() when reporting in-use state for idle mode.
- OobChannel shares the same Executor as Subchannel.asChannel(). Because the latter is not a ManagedChannel and doesn't have life-cycle, thus can't determine when to return the Executor to a pool, the Executor is now returned only when ManagedChannelImpl is terminated.
The transport test flakes at the timeout(100) about .05% of the time.
There's really no reason it should have a smaller timeout compared to
the other timeouts.
The timeout(250) wasn't flaking at all, but it should follow the
convention.
This is the first step of smoothly changing the CallCredentials API.
Security level and authority are parameters required to be passed to
applyRequestMetadata(). This change wraps them, along with
MethodDescriptor and the transport attributes to RequestInfo, which is
more clear to the implementers.
ATTR_SECURITY_LEVEL is moved to the internal GrpcAttributes and
annotated as TransportAttr, because transports are required to set it,
but no user is actually reading them from
{Client,Server}Call.getAttributes().
ATTR_AUTHORITY is removed, because no transport is overriding it.
All involved interfaces are changed to abstract classes, as this will
make further API changes smoother.
The CallCredentials name is stabilized, thus we first introduce
CallCredentials2, ask CallCredentials implementations to migrate to
it, while GRPC accepting both at the same time, then replace
CallCredentials with CallCredentials2.
This attempts to fix a flake seen exactly once with the
currently-disabled OkHttpTransportTest.flowControlPushBack:
```
java.lang.AssertionError
at org.junit.Assert.fail(Assert.java:86)
at org.junit.Assert.assertTrue(Assert.java:41)
at org.junit.Assert.assertTrue(Assert.java:52)
at io.grpc.internal.testing.AbstractTransportTest.flowControlPushBack(AbstractTransportTest.java:1300)
```
That was a failure for assertTrue(serverStream.isReady()), because the
awaitOnReady was finding the previous invocation of onReady. We now
track how many times it has been called. This was a bug introduced in
a8db154702 but wouldn't have been noticed since the in-process transport
is deterministic.
This is an API used to coordinate across packages and must live in
`io.grpc`.
Prepending `Internal` makes it easier to detect and hide this class
from public visibility when using certain build tools.
fixes#4796
Most of the changes are changing the signature of newClientTransport.
Since this is annoying, I choose to introduce a ClientTransportOptions
object to avoid the churn in the future.
With ClientTransportOptions in place, there's only a few lines necessary
of plumbing for the Attributes: add the field to ClientTransportOptions
and populate it in InternalSubchannel. There are no consumers of the
field in this commit.
