* okhttp: add PerfMark tracing for okhttp transport
* change task for AsyncSink to give more accurate task description
* add final to field tag
* add PerfMark dependency in okhttp package bazel
The former is deprecated and replaced by the latter in Mockito 2.
However, there is a functional difference: ArgumentMatchers will reject
`null` and check the type if the matcher specified a type (e.g.
`any(Class)` or `anyInt()`). `any()` will remain to accept anything.
As mentioned in 5188[1], the default used with the enableKeepAlive API
conflicted with the default server enforcement. Instead of fixing it,
remove it. These APIs were deprecated in v1.3.0 in April 2017.

io.grpc has fewer dependencies than io.grpc.internal. Moving it to a
separate artifact lets users use the API without bringing in the deps.
If the library has an optional dependency on grpc, that can be quite
convenient.
We now version-pin both grpc-api and grpc-core, since both contain
internal APIs.
I had to change a few tests in grpc-api to avoid FakeClock. Moving
FakeClock to grpc-api was difficult because it uses
io.grpc.internal.TimeProvider, which can't be moved since it is a
production class. Having grpc-api's tests depend on grpc-core's test
classes would be weird and cause a circular dependincy. Having
grpc-api's tests depend on grpc-core is likely possible, but weird and
fairly unnecessary at this point. So instead I rewrote the tests to
avoid FakeClock.
Fixes#1447
* okhttp: add verbose logging for OkHttp HTTP/2 frames to include brief frame content.
* fix small details and typo issues
* fix branch condition (it's a typo) for logging the whole buffer
* remove redudent log level checking, always not log entire buffer
* convert ByteString to String to avoid printing 'hex=' prefix
* add test for OkHttpFrameLogger for inbound http frames
* refactor OkHttpFrameLogger's help method
* add Constructor for testing and missing logHeaders
* add http/2 framelogger test for outbound side
* use ArgumentMatchers instead of Matchers
* replace assertTrue with Truth.assertThat
* assert buffer log with exact length match instead of <=
This is needed for GRPCLB pick_first support, which needs to attach
tokens to headers, and the tokens are per server. In pick_first, all
addresses are in a single Subchannel, thus the LoadBalancer needs to
know which backend is used for a new stream.
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.
Context: [#4159 (comment)](https://github.com/grpc/grpc-java/issues/4159#issuecomment-415827641)
`Attributes` is appropriate for plumbing optional objects, especially useful for a long plumbing path where components in the middle may not care or see all objects in the container. It's not the case for the `params` on `newNewResolver()`. Both the default port and the proxy detector are guaranteed to be there and the plumbing path is very short. In this case, a first-class object is more appropriate and easier to use.
The `Helper` will also have `getSynchronizationContext()` (#2649) and a method to parse and validate service config. We we also considering merging `Listener` into the `Helper`, to make `NameResolver` match the `LoadBalancer` API.
Combine the public `ProxyParameters` and the internal `ProxySocketAddress` as `HttpConnectProxiedSocketAddress`. The more specific name signifies the type of the proxy we currently support, and makes room for other proxy types (e.g., SOCKS) in the future. The combination simplifies NameResolver implementation.
Introduce `ProxiedSocketAddress` as the base class that is returned by `ProxyDetector`, mainly for clarification and documentation. Added documentation about proxy in general on `ProxyDetector`.
This will reduce the method count, as okhttp's copy of ConnectionSpec will no
longer be retained when ProGuarded. It was deprecated in 25f357699, 10 months
ago.
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.
Optimize OkHttp transport's memory use by getting rid of queuing writes in
AsyncFrameWriter. If any write is pending due to connection issue or by flow
control, AsyncFrameWriter can use at least 8K per each task (task includes
buffer) even if the actual payload is very small. To merge pending writes,
Async mechanism is moved from AsyncFrameWriter to AsyncSink (AsyncSink
is used by okio's FrameWriter). AsyncSink is still relying on okio's buffer to
decide merging writes or not.
Resolves#4860
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.
This will allow enabling Error Prone on JDK 10+ (after
updating the net.ltgt.errorprone plugin), and is also a
prerequisite to that plugin update.
Also remove net.ltgt.apt plugin, as Gradle has native
support for annotationProcessor.
This is a rename of the pre-existing Netty builder method, so aliases
were added to the Netty builders.
Fixes#4050. This API was a minor rename to the pre-existing Netty API,
so has already undergone API review and thus is not ExperimentalApi.
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.
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.
