ea65746947 fix(filer): end metadata subscriptions before gRPC GracefulStop on shutdown (#11663)
* fix(filer): end metadata subscriptions before gRPC GracefulStop on shutdown

GracefulStop waits for every open stream. The filer's own MetaAggregator
subscription and, under -s3, the S3 gateway's IAM subscription live in
the same process and only end when the filer shuts down, which happens
after GracefulStop - so every shutdown sat out the full 15s timeout.

StopSubscriptions ends them (and any started later) right after leaving
the lock ring; the handlers derive their context from the stream and
this signal. Measured on weed server -s3: stop 25.6s -> 10.7s, and
0.6s with -volume.preStopSeconds=0.

* fix(filer): end stopped subscriptions with Unavailable, not cleanly

A subscription that StopSubscriptions cut short returned nil. The client
reads that as io.EOF, "caught up, done", and util.RetryUntil - which the
S3 gateway and mount follow with - stops on nil. A separate S3 gateway
therefore never resubscribed after its filer restarted (measured: 0
subscriptions in 25s after the restart; upstream master and this fix: it
is back within a second).

endOfSubscription now turns that clean end into codes.Unavailable, which
is what a dropped connection looks like, so followers reconnect. Errors
pass through, and so does the end of a stream the client closed.

A subscriber that has stopped reading is still left to GracefulStop's
timeout: its handler sits in stream.Send, which only the end of the
stream releases, and grpc-go does not allow Send after the handler
returns. Documented at StopSubscriptions. Shutdown under weed server -s3
is unchanged at 10.7s.

* fix(filer): interrupt in-flight subscription reads and end them Unavailable

StopSubscriptions only reached the wait points: a handler replaying the
ring or the persisted log kept streaming until the pass ended, and a pass
cut short at a ctx.Err() boundary (the replay semaphore, chunk ref
collection, ref sends) returned a wrapped context.Canceled, which reads as
codes.Canceled on the wire - a code transient-error classifiers treat as
non-retryable.

eachLogEntryFn and sendRefsBatched now check the subscription context per
entry/batch, and endOfSubscription reports a context.Canceled cut short by
the stop signal as codes.Unavailable, same as a clean end it interrupted.

* filer: honor the subscription context in the pipelined sender

A subscriber that stops reading wedges sendLoop in stream.Send; Send and
Close then blocked past StopSubscriptions, so GracefulStop still waited out
its timeout. Both now return when the subscription context ends, letting the
handler return and gRPC tear the stream down.

* filer: stop sendLoop from starting sends after the subscription ends

With Send and Close released by the subscription context, sendLoop could
still issue a stream.Send after the handler returned. Gate every send on
the context so at most the in-flight Send overlaps teardown - and the
stream's own teardown is what unblocks it.
