Stephen J Day	cd72819b53	archive, cio, cmd, linux: use buffer pools To avoid buffer bloat in long running processes, we try to use buffer pools where possible. This is meant to address shim memory usage issues, but may not be the root cause. Signed-off-by: Stephen J Day <stephen.day@docker.com>	2018-01-22 13:52:06 -08:00

Daniel Dao	8e53465842	use epoll to manage console i/o in linux this adds a `platform` interface for shim service to manage platform-specific behaviors such as I/O (which uses epoll in linux to work around bugs with applications that closes all consoles i.e. https://github.com/opencontainers/runc/pull/1434 and https://github.com/moby/moby/issues/27202) Its expected that we only have 1 epollfd per containerd_shim to manage all processes. Since all the work are done outside of the container runtime, upgrading of runc is not required and should be done separately. Signed-off-by: Daniel Dao <dqminh89@gmail.com>	2017-07-30 10:50:39 +01:00
