Make the statbuf field public. This means you no longer have to use
req->ptr - though that still works and will continue to work for the
foreseeable future.
Fixes#704.
This changes the prototype of uv_run() from:
int uv_run(uv_loop_t* loop);
To:
int uv_run(uv_loop_t* loop, uv_run_mode mode);
Where `mode` is UV_RUN_DEFAULT, UV_RUN_ONCE or UV_RUN_NOWAIT.
Fixes#683.
Allows for running the event loop in 3 modes:
* default: loop runs until the refcount drops to zero
* once: poll for events only once and block until one is handled
* nowait: poll for events only once but don't block if there are
no pending events
Bert Belder informs me the current approach where a request is immediately
cancelled, is impossible to implement on Windows.
Rework the API to always invoke the "done" callback with an UV_ECANCELED error
code.
This can be used in conjuction with uv_run_once() to poll in one thread and run
the event loop's event callbacks in another.
Useful for embedding libuv's event loop in another event loop.
You can now select to build a shared object at configure time:
$ ./gyp_uv -Dcomponent=shared_library -Dlibrary=shared_library
And build it with:
$ make -C out BUILDTYPE=Debug # or BUILDTYPE=Release
Or, if you use ninja:
$ ninja -C out/Debug
Adds initial libuv build/platform support for AIX. Builds work using gcc or the
IBM XL C compiler using its gxlc wrapper. Platform support is added for
uv_hrtime, uv_exepath, uv_get_free_memory, uv_get_total_memory, uv_loadavg,
uv_uptime, uv_cpu_info, uv_interface_addresses.
uv_fs_poll_t has an embedded uv_timer_t handle that got closed at a time when
the memory of the encapsulating handle might already have been deallocated.
Solve that by moving the poller's state into a structure that is allocated on
the heap and can be freed independently.
The Sun Studio compiler did not define any of the symbols used to determine if
the system was a unix-like system or not causing it to include the windows
header.

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.
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.
