This avoids the dependency on animalsniffer-annotations. grpc-api, and
particularly grpc-context, are used many low-level places and it is
beneficial for them to be very low dependency. This brings grpc-context
back to zero-dependency.
In 61f19d707a I swapped the signatures to use the version catalog. But I
failed to preserve the `@signature` extension and it all seemed to
work... But in fact all the animalsniffer tasks were completing as
SKIPPED as they lacked signatures. The build.gradle changes in this
commit are to fix that while still using version catalog.
But while it was broken violations crept in. Most violations weren't
too important and we're not surprised went unnoticed. For example, Netty
with TLS has long required the Java 8 API
`setEndpointIdentificationAlgorithm()`, so using `Optional` in the same
code path didn't harm anything in particular. I still swapped it to
Guava's `Optional` to avoid overuse of `@IgnoreJRERequirement`.
One important violation has not been fixed and instead I've disabled the
android signature in api/build.gradle for the moment. The violation is
in StatusException using the `fillInStackTrace` overload of Exception.
This problem [had been noticed][PR11066], but we couldn't figure out
what was going on. AnimalSniffer is now noticing this and agreeing with
the internal linter. There is still a question of why our interop tests
failed to notice this, but given they are no longer running on pre-API
level 24, that may forever be a mystery.
[PR11066]: https://github.com/grpc/grpc-java/pull/11066
* Add S2AStub cleanup handler.
* Give TLS and Cleanup handlers name + update comment.
* Don't add TLS handler twice.
* Don't remove explicitly, since done by fireProtocolNegotiationEvent.
* plumb S2AStub close to handshake end + add integration test.
* close stub when TLS negotiation fails.
Combined success / error status passed via ResolutionResult to the NameResolver.Listener2 interface's onResult2 method - Addresses in the success case or address resolution error in the failure case now get set in ResolutionResult::addressesOrError by the internal name resolvers.
* S2AHandshakerServiceChannel doesn't use custom event loop.
* use executorPool.
* log when channel not shutdown.
* use a cached threadpool.
* update non-executor version.
Bazel had the dependency added because of #5046, where Guava was
depending on it as compile-only and Bazel build have "unknown enum
constant" warnings. Guava now has a compile dependency on j2objc, so
this workaround is no longer needed. There are currently no version skew
issues in Gradle, which was the only usage.
Today, deframer errors cancel the stream without communicating a status code
to the peer. This change causes deframer errors to trigger a best-effort
attempt to send trailers with a status code so that the peer understands
why the stream is being closed.
Fixes#3996
`sendGrpcFrame` owns the buffer in `SendGrpcFrameCommand`. If the frame is not handed off to netty, it needs to be released in the method.
https://github.com/grpc/grpc-java/issues/11115
Handles Netty write frame failures caused by issues in the Netty
itself.
Normally we don't need to do anything on frame write failures because
the cause of a failed future would be an IO error that resulted in
the stream closure. Prior to this PR we treated these issues as a
noop, except the initial headers write on the client side.
However, a case like netty/netty#13805 (a bug in generating next
stream id) resulted in an unclosed stream on our side. This PR adds
write frame future failure handlers that ensures the stream is
cancelled, and the cause is propagated via Status.
Fixes#10849
The recommended way to load dependencies from `rules_jvm_external`
is to make use of the `@maven` workspace, and the most readable
way of doing that is to use the `artifact` macro provides.
This removes the need to generate the "compat" namespaces, which
`rules_jvm_external` provided for backwards compatibility with
older releases. This change also sets things up for supporting
`bzlmod`: this requires all workspaces accessed by a library to
be named "up front" in the `MODULE.bazel` file. This way, the
only repo that needs to be exported is `@maven`, rather than the
current huge list.
* Allow the queued byte threshold for a Stream to be ready to be configurable
- on clients this is exposed by setting a CallOption
- on servers this is configured by calling a method on ServerCall or ServerStreamListener
`project(':grpc-netty').configurations` requires the grpc-netty project
to be configured, which requires evaluationDependsOn. Without
evaluationDependsOn, project loading order is arbitrary and you can get
random errors after small configuration changes.
SelfSignedCertificate is not available on Java 17 because
OpenJdkSelfSignedCertGenerator is not available. This only impacted
tests.
AccessController is being removed, and these locations are doing simple
reflection which is unlikely to require it even when a security policy
is in effect. There's other places we do reflection without the
AccessController, so either no security policies care or the users can
update their policies to allow it.
`-link` does I/O to download the package list, for every javadoc
invocation. There is no caching, so this happens many times per build.
Swap to offline mode to avoid spamming the servers, and avoid build
failures if the servers aren't entirely healthy.
It wasn't actually being used. Since Java 8u252 in early 2020 we've been
using ALPN from the JDK. The Jetty ALPN Agent has been a noop.
We do keep the Jetty ALPN support in the code and tests, but we don't
have the infrastructure to actually run it.
Add the 'fake' dependency to grpc-netty instead of grpc-core.
grpc-okhttp already depends on grpc-util and probably would be fine
without round_robin on Android.
There's not actually a circular dependency, but some tools can't handle
the compile vs runtime distinction. Such tools are broken, but fixes
have been slow and this approach works with no real downfalls.
Works around #10576#10701
* netty: improve server handling of writes to reset streams
A server stream can be reset by the client while server writes are still queued. After the stream is reset, the netty connection will forget the stream object. The `NettyServerHandler` must deal with that situation. `sendResponseHandlers` already had some code to do that. This change standardizes that code and adds it to `sendGrpcFrame`. This fixes a potential bug where a `SendGrpcFrameCommand` with `endOfStream=true` would raise an `AssertionError` if written to a reset stream. (This bug is not currently reachable because `endOfStream=false` for all server `SendGrpcFrameCommand` objects.)
* Do not call into the encoder when we know the stream is gone.
6efa9ee3 added `volatile` to `attributes` after TSAN detected a data
race that was added in 91d15ce4. The race was because attributes may be
read from another thread after `transportReady()`, and the
post-filtering assignment occurred after `transportReady()`. The code
now filters the attributes separately so they are updated before calling
`transportReady()`.
Original TSAN failure:

The KeepAliveManager clamps the keepalive and keepalive time values such that the result is larger than the minimum values specified here. Therefore, a second check here is unnecessary.
All the changes outside libs.versions.toml and examples were
because of ErrorProne. It didn't actually find anything to fix; signal
vs noise has gotten pretty bad with the newer checks.
Status was changed for ErrorProne's SuperCallToObjectMethod. With the
old code it didn't notice the trivial implementation. The fail-for-test
code wasn't used, so it was easiest to just remove it.
Some of the libs had their versions inlined; now that we have
:checkForUpdates it isn't much of a risk for versions to diverge when
there's only a few artifacts sharing a version. If we need 4+ artifacts
to have the same version, then it makes sense to still use a shared
version.
Dependencies not upgraded: google-auth-libray, mockito, netty, cronet
The behavior purposefully mirrors that of Netty's
AbstractHttp2ConnectionHandlerBuilder.decoderEnforceMaxRstFramesPerWindow().
That API is not available to our code as we extend the
Http2ConnectionHandler, but we want our API to be able to delegate to
Netty's in the future if that ever becomes possible.
Huffman in the datacenter doesn't add much value in the common cases. It could be useful to turn on huffman based on the connection latency (say, >10ms means "assume cross-datacenter") but the Netty API doesn't lend it to that. The savings here aren't huge and it is expensive; the table provides the biggest savings.
* core, netty, okhttp: implement new logic for nameResolverFactory API in channelBuilder
fix ManagedChannelImpl to use NameResolverRegistry instead of NameResolverFactory
fix the ManagedChannelImplBuilder and remove nameResolverFactory
* Integrate target parsing and NameResolverProvider searching
Actually creating the name resolver is now delayed to the end of
ManagedChannelImpl.getNameResolver; we don't want to call into the name
resolver to determine if we should use the name resolver.
Added getDefaultScheme() to NameResolverRegistry to avoid needing
NameResolver.Factory.
