The new plugin uses a newer version of animalsniffer, allows overriding
the animalsniffer version used, and has up-to-date handling. The
up-to-date handling cuts fully incremental parallel build times in half,
from 5.5s to 2.7s.
The previous plugin was supposed to be verifying tests. However, either
it wasn't verifying them or its verification was broken.
The LBv2 setter was added in #2658 as an abstract method, which breaks
anyone who implements ManagedChannelBuilder. Here we add a default
implementation that throws.
This is needed because in interceptor tests, often the types cannot
be changed. The void methods stay for users who are writing tests
where they actually don't care about types. The noop methods
require types to be specified. This is for users who don't care
about the implementation. These represent different levels of
commitment.
This eases the transition of code Mocking MethodDescriptor, which
breaks in this release.
In some environments DNS is not available and is performed by the
CONNECT proxy. Nothing "special" should need to be done for these
environments, but the previous support took shortcuts which knowingly
would not support such environments.
This change should fix both OkHttp and Netty. Netty's
Bootstrap.connect() resolved the name immediately whereas using
ChannelPipeline.connect() waits until the address reaches the end of the
pipeline. Netty uses NetUtil.toSocketAddressString() to get the name of
the address, which uses InetSocketAddress.getHostString() when
available.
OkHttp is still using InetSocketAddress.getHostName() which may issue
reverse DNS lookups. However, if the reverse DNS lookup fails, it should
convert the IP to a textual string like getHostString(). So as long as
the reverse DNS maps to the same machine as the IP, there should only be
performance concerns, not correctness issues. Since the DnsNameResolver
is creating unresolved addresses, the reverse DNS lookups shouldn't
occur in the common case.
Because "core"'s test source already depends on "testing", e.g.,
`core/src/test/java/io/grpc/internal/ServerCallImplTest.java` uses
`testing/src/main/java/io/grpc/internal/testing/StatsTestUtils.java`,
which forms a circular dependency.
This change moves the StatsContext setter accessors from "core"'s test
source to "testing".
Resolves#2651
This removes an abuse of scheduled executor in ManagedChannelImpl. The executor
was used to avoid deadlocking. Now we run the work on the same thread, but
delay it until locks have been released.
There is no need to fix ManagedChannelImpl2. Due to its different
threading model it didn't have need to abuse the scheduledExecutor.
Fixes#2444
These are only used in internal tests. In production,
StatsContextFactory is loaded by the "Instrumentation" library and must
be one per process, thus we won't allow setting it on a per-channel or
per-server basis.
* Remove else, make it easier to read
* Ready subchanns list will be at max the same as the input list
* Make status private, add pkg-private getter for tests
* Remove empty field, cache size, simplify logic
Make list unmodifiable. Document index with GuardedBy (see #nextSubchannel())
add `getAttributes()` to `ClientStream` and `ClientCall` to be able to share clientTransport
information such as socket TOS with higher lever API's, once the RPC picks up an active transport that is ready to use.
Previously it does it at shutdown, which was wrong because executor may
still be used before the server is terminated.
Resolves#2034
Uses ObjectPool to make this change testable. Cleans up test and makes
it mostly single-threaded, except for two deadlock tests that have to be
multi-threaded.
If a LoadBalancer2 is passed in, the builder will create ManagedChannelImpl2 instead of ManagedChannelImpl. This allows us to test the LBv2 classes on a large scale.
1. Adapt to LoadBalancer2 interface. Channel holds on to a single
DelayedClientTransport2.
2. Lock-free: every channel state mutation, including Subchannel
mutations, calling into LoadBalancer, idleness and shutdown, is made
from channelExecutor.
3. Idleness grace period is no longer needed.
In upstream, Census is renamed to "Instrumentation". `com.google.census` is renamed to `com.google.instrumentation.stats`.
In gRPC, "census" in every name is replaced by "stats".
Besides API changes, this implementation is also up-to-date with the
latest design:
1. Delegate to round-robin and pick-first policies if requested by
the naming system.
2. OOB channels to LoadBalancer always use the LB authority provided by
the naming system.
3. Never send application RPCs to balancer addresses, even if the
address returns UNIMPLEMENTED error.
"Because of spurious wakeups, wait() must always be called in a loop".
Got rid of wait().
"If you return or throw from a finally, then values returned or thrown from the try-catch block will be ignored. Consider using try-with-resources instead."
Ignored the exception thrown from finally.
