This commit changes how the event loop determines if it needs to stay alive. Previously, an internal counter was increased whenever a handle got created and decreased again when the handle was closed. While conceptually simple, it turned out hard to work with: you often want to keep the event loop alive only if the handle is actually doing something. Stopped or inactive handles were a frequent source of hanging event loops. That's why this commit changes the reference counting scheme to a model where a handle only references the event loop when it's active. 'Active' means different things for different handle types, e.g.: * timers: ticking * sockets: reading, writing or listening * processes: always active (for now, subject to change) * idle, check, prepare: only active when started This commit also changes how the uv_ref() and uv_unref() functions work: they now operate on the level of individual handles, not the whole event loop. The Windows implementation was done by Bert Belder. |
