When GracefulStop is called gRPC waits for current requests to finish before closing. While this is generally the behavior we want, it is not always same for the History.Listen endpoint. That endpoint is usually open even if buildkit is not actively processing any builds, because client may be waiting for new events. The new logic is that if GracefulStop will happen, history will close active listeners if there are no active builds. If there are active builds then active listeners will be closed after all the active builds have completed their finalizers. Signed-off-by: Tonis Tiigi <[email protected]>

depends on #5515When GracefulStop is called, gRPC waits for current requests to finish
before closing. While this is generally the behavior we want, it is
not always the same for the History.Listen endpoint. That endpoint is
usually open even if buildkit is not actively processing any builds,
because the client may be waiting for new events.
The new logic is that if GracefulStop happens, history will
close active listeners if there are no active builds. If there are
active builds, then active listeners will be closed after all the
active builds have completed their finalizers.
