It is only safe to shutdown the executor if onClose() is called. Normal
RPC completions (both success and failure) will see the future complete,
so this only avoids shutting down in stranger cases like an interceptor
throwing an exception.
* stub: Have ClientCalls.ThreadlessExecutor reject Runnables after end of RPC
Changes originally proposed as part of #7106.
Fixes#3557
* add environment variable rejectExecutedException

Previous versions of error prone were incompatible with Java 17 javac.
In grpc-api, errorprone is now api dependency because it is on a public
API. I was happy to see that Gradle failed the build without the dep
change, although the error message wasn't super clear as to the cause.
It seems that previously -PerrorProne=false did nothing. I'm guessing
this is due to a behavior change of Gradle at some point. Swapping to
using the project does build without errorProne, although the build
fails with Javac complaining certain classes are unavailable. It's
unclear why. It doesn't seem to be caused by the error-prone plugin.
I've left it failing as a pre-existing issue.
ClientCalls/ServerCalls had Deprecated removed from some methods because
they were only deprecated in the internal class, not the API. And with
Deprecated, InlineMeSuggester complained.
I'm finding InlineMeSuggester to be overzealous, complaining about
package-private methods. In time we may figure out how to use it better,
or we may request changes to the checker in error-prone.
setOnCancelHandler tells gRPC that the application is handling
cancellation. But it's fine to have noop behavior within the handler
itself if the application doesn't need it. It is just a way to opt-in to
the more recent no-exception-from-onNext behavior. Let's mention this
use-case in the docs to make it more obvious it is a possibility.
Came up as part of #8409.
We don't want other APIs to copy the stub-based API to attach the
interceptor. The API has a shorter name, but isn't actually all that
easier to use and isn't fluent like using the interceptor API.
These are _very_ old methods, so we won't be quick to delete them. Seems
we should have them deprecated at least a year or two; they are easy to
maintain in the mean time.
See API Review notes in #1789
This can be used by annotation processors to avoid processing the
gRPC-generated code. The normal Generated annotation only has SOURCE
retention, so isn't available to annotation processors.
I don't include the service name within the annotation as that assumes
we'll never have need for any other type of generated class. If there's
a request for exposing service name via an annotation in the future, we
can make an RpcService annotation or the like.
Fixes#8158
This reverts commit 61e0f30 (#7798).
Our stub/core implementation had a bug (#7921) that might make it possible to leak cancellation through to the executor multiple times, typically when a custom interceptor is used. Revert this commit because import of grpc to google internal fails. We think the bug found in the import is legit and in our code. So we revert this change to avoid hurting users until the underlying issue is fixed.
Unary are far more common than streaming, and we're throwing for unary even
though it doesn't help the service. Let's stop doing that. We also stop
throwing in onComplete() for all cases, because it doesn't help any service;
it doesn't stop the service's processing and isn't even all that informative
since the cancellation can happen even after onComplete() is called.
This avoids the "changes" description, which could be understood to mean that
the transition is important instead of the steady-state and thus a callback
might not be called (which is not the case).
Much of the language was copied from ServerCall.
This can provide a ~2x performance increase to Netty and 40% increase
for OkHttp. Netty async saw a ~3x gain from MigratingDeframer, so
blocking trails behind a bit. But OkHttp's async gains from
MigratingDeframer were also 40%, so this provides the same gain to
blocking.
This splits server-side flow control from client-side, but tailors the API for
each case. Client-side continues having disableAutoRequestWithInitial(). While
client-side could have disableAutoRequest(), it seems like it will only rarely
be used and disableAutoRequestWithInitial(0) isn't that bad. So we leave it off
for now; we can always add it in the future.
Add a new disableAutoRequest method that disables all automatic requests while disableAutoInboundFlowControl maintains existing behavior.
The default behavior of requesting initial messages is applied even if disableAutoInboundFlowControl is called. ServerCalls disables all automatic flow control which is much more useful in case the user can't handle incoming messages until some time after the call has started. This change creates a new StartableListener that has an onStart method that is invoked when the call is started which makes initial requests if necessary.
See #6806
This is already in the documentation in CallStreamObserver, but if the user
gets here the error didn't provide an actionable next step. The message now
provides more help of how they should have called the methods instead of
feeling more like a brick wall.
