Demonstrates temporary event loop stall with uv-unix. The issue is that pending
requests aren't processed until the next event (I/O, timeout, etc.) happens.
See #446, #447 and #448.
Previously the only option was to create a pipe or an ipc channel. This
patch makes it possible to inherit a handle that is already open in the
parent process. There is also room for setting more than just stdin,
stdout and stderr, although this is not supported yet.
uv_timer_start() no longer returns an error when the timer is already active,
now it just updates the timer. Consistent with the uv-win implementation.
Fixes#425.
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.
Detaching doesn't work yet, the setsid() call fails and leaves the child process
attached to the parent's session.
Revert "test: Add test case for spawning detached child processes."
Revert "win: Implement options.detached for uv_spawn() for Windows."
Revert "unix: Implement options.detached for uv_spawn() for unix."
Revert "Add "detached" member to uv_process_options_t to denote whether a child
process should spawn detached from its parent."
