From 2622d2f39e85027b0b8baef693510ef4222818a1 Mon Sep 17 00:00:00 2001 From: Andrii Grynenko Date: Wed, 18 May 2016 22:57:40 -0700 Subject: [PATCH] Move fibers out of experimental Summary: folly::fibers have been used by mcrouter for more than 2 years, so not really experimental.

First fiber-task will grab a lock and then suspend waiting on a fibers::Baton. Then second fiber-task will be run and it will try to grab a lock. Unlike system threads, fiber-task can be only suspended explicitly, so the whole system thread will be blocked waiting on the lock, and we end up with a dead-lock.

There're generally two ways we can solve this problem. Ideally we would re-design the program to never not hold any locks when fiber-task is suspended. However if we are absolutely sure we need that lock - folly::fibers library provides some fiber-task-aware lock implementations (e.g. -TimedMutex).

Similarly to system threads, every fiber-task has some stack space assigned to it. Stack usage goes up with the number of nested function calls and objects allocated on the stack. folly::fibers implementation only supports fiber-tasks with fixed stack size. If you want to have many fiber-tasks running concurrently - you need to reduce the amount of stack assigned to each fiber-task, otherwise you may run out of memory.

NOTE: folly::fibers doesn't support killing fiber-tasks in-flight (for similar reasons you can't kill a thread). If fibers::FiberManager has any outstanding fiber-tasks, when folly::EventBase is being destroyed, it will keep running the event loop until all those tasks are finished.

GDB integration

folly::fibers provide some GDB extensions which can be very useful for debugging. To load them simply the following in dbg console:
