Invalidate file descriptor when closing `uv_fs_event_t` handle. Note
that `uv__io_stop` is just removing `fd` from `loop->watchers` and not
actually invalidating all consequent events in a `kevent()` results.
fixjoyent/node#1101
Reopen the file descriptor when it refers to a tty. This lets us put the
tty in non-blocking mode without affecting other processes that share it
with us.
This brings back commit 31f9fbc, which was reverted in 20bb1bf. The OSX
select trick is working now.
Original patch by @bnoordhuis
If the same file description is open in two different processes, then
closing the file descriptor is not sufficient to deregister it from the
epoll instance (as described in epoll(7)), resulting in spurious events
that cause the event loop to spin repeatedly. So always explicitly
deregister it.
Fixes#1099.

Introduce `int uv_pipe_pending_count(uv_pipe_t*)` and
`uv_handle_type uv_pipe_pending_type(uv_pipe_t*)`. They should be
used in IPC pipe's read cb to accept incoming handles:
int count = uv_pipe_pending_count(pipe);
int i;
for (i = 0; i < count; i++) {
uv_handle_type type = uv_pipe_pending_type(pipe);
/* ... */
uv_accept(...);
}
When the supplied buffer is not big enough and UV_ENOBUFS is
returned, hint the user about the required size by setting
the len paramemeter to the required value.
Applies to:
- uv_pipe_getsockname
- uv_fs_event_getpath
- uv_fs_poll_getpath
This improves API consistency with uv_read and uv_write and may
improve efficiency for some uses. Vectored IO is emulated when the
requisite system calls are unavailable.
These functions supersede uv_loop_new and uv_loop_delete.
uv_loop_init initialized a user allocated loop and uv_loop_close
removes all associated resources a loop uses after it has finished
execution.
uv_loop_new and uv_loop_delete are now deprecated.

Replace the red-black tree with a heap. The most common operation that
libuv performs on timers is looking up the first timer to expire. With
a red-black tree, that operation is O(log n). With a heap, it's O(1).
The event_handle field of unused accept requests was not being
initialized properly. As a result, uv_tcp_endgame would try to close
an invalid handle and this could lead to unexpected behavior.
This fixes node.js test test-cluster-disconnect.js on Windows.
