This commit aligns the naming of the Bazel Maven jars with the names
used by Bazel's migration-tooling project:
https://github.com/bazelbuild/migration-tooling
Unfortunately, we can't fix @com_google_protobuf_java because it's
required by Bazel itself.
Fixes#3328
This API change allows storage implementations to put some state
information into the return value, giving it the ability to act
as a cookie. In environments where contexts can be replaced, the
current original context can be stashed there and be restored
when detach is called.
null class loader means to use the bootstrap class loader, which would
normally make sense. However, Robolectric tests run on OpenJDK and
provide the Android environment as part of the application, so "Android"
won't be present in the bootstrap class loader.
EmbeddedChannel now runs all pending tasks when the Channel is closed.
This caused the Http2ConnectionHandler to clear deframer references (on
channelInactive) on errors when it previously didn't. Now that the
errors were handled more fully, it exposed bugs in tests.
This is a big, but mostly mechanical change. The newly added Test*StreamTracer classes are designed to be extended which is why they are non final and have protected fields. There are a few notable things in this:
1. verifyNoMoreInteractions is gone. The API for StreamTracers doesn't make this guarantee. I have recovered this behavior by failing duplicate calls. This has resulted in a few bugs in the test code being fixed.
2. StreamTracers cannot be mocked anymore. Tracers need to be thread safe, which mocks simply are not. This leads to a HUGE number of reports when trying to find real races in gRPC.
3. If these classes are useful, we can promote them out of internal. I just put them here out of convenience.
This fixes sign-compare and maybe-unintialized. An unused-value warning
remains.
I changed LogHelper to always call abort so the compiler would know the
method does not return, which fixed the maxbe-uninitialized warning.
If onTransportActive ran while SendPing was already scheduled, we would
schedule another SendPing, which seems fine, but the server might observe
us sending pings too quickly, and make us GOAWAY.
Fixes#3274.
Previously only when all addresses returned by NameResolver are
balancers would GRPCLB be forced. This change is a follow-up of
https://github.com/grpc/grpc/pull/10258
As discussed in #1914, we need CallCredentials and MoreCallCredentials
to be stable, but there's less of a strong need for the contents of
CallCredentials to be stable. We're willing to commit to the name,
without needing to commit to the plumbing.
* netty: support `status()` on Headers
Recent Netty change a91df58ca1
caused the `status()` method to be invoked, which AbstractHttp2Headers does not implement.
This change is necesary to upgrade to Netty 4.1.14
```

Use deadline on client calls lead to create TimeoutException even
if deadline not occurs yet. fillStacktrack very expensive operation
that allocate many unnecessary objects in heap. Now exception
creates only when deadline occurs.
Close#3272
Coupled with the similar change on server-side, this removes the need for a
thread when using Netty. For InProcess and OkHttp, it would allow us to let the
user to provide the scheduler for tests or application-wide thread sharing.

Using static initialization is possible, but quite complex to handle
logging and circular loading. Lazy loading prevents an entire class of
circular dependencies.
This is only implementing how subchannel state changes are hooked up to channel state APIs. Debates in state semantics and transition rules for loadbalanced channel such as #2873 are not addressed. Any changes in state semantics and transition rules in the future can be easily adapted.
For Netty, this reduces the number of threads necessary for servers (although
until channel is converted, actual number of threads isn't impacted) and
naturally reduces contention and timeout latency.
For InProcess, this gets us closer to allowing applications to provide all
executors, which is especially useful during tests.
Class.forName(String) is understood by ProGuard, removing the need for
manual ProGuard configuration and allows ProGuard to rename the provider
classes. Previously the provider classes could not be renamed.
Fixes#2633
Previously anyone could create metadata keys with a leading ":", due to not having a way to prevent it. This change effectively only allows internal code to make use of this.
