From 11eff929e24cae59ed21c2f3a0bde22a6dbe0d91 Mon Sep 17 00:00:00 2001 From: Guantao Liu Date: Mon, 7 Jan 2019 18:22:50 -0800 Subject: Avoid the thread jump in server callback APIs. Add a utility function in iomgr to check whether the caller thread is a worker for any background poller, and keep grpc combiner from offloading closures to the default executor if the current thread is a worker for any background poller. --- src/core/lib/iomgr/iomgr_internal.cc | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/core/lib/iomgr/iomgr_internal.cc') diff --git a/src/core/lib/iomgr/iomgr_internal.cc b/src/core/lib/iomgr/iomgr_internal.cc index b6c9211865..e68b1cf581 100644 --- a/src/core/lib/iomgr/iomgr_internal.cc +++ b/src/core/lib/iomgr/iomgr_internal.cc @@ -45,3 +45,7 @@ void grpc_iomgr_platform_shutdown() { iomgr_platform_vtable->shutdown(); } void grpc_iomgr_platform_shutdown_background_closure() { iomgr_platform_vtable->shutdown_background_closure(); } + +bool grpc_iomgr_platform_is_any_background_poller_thread() { + return iomgr_platform_vtable->is_any_background_poller_thread(); +} -- cgit v1.2.3
