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.
It makes the assumption that if you try to write to a localhost socket
often enough, eventually its send queue will fill up - which doesn't
happen if the machine it's running on is fast enough.
On i386, it does not need packing; it's 12 bytes packed or unpacked.
On ARM, it's actively harmful: the struct is 12 bytes when packed and
16 bytes when unpacked.
uv_guess_handle is currently squelching both fifo and all
sockets on to the UV_NAMED_PIPE type. Rather than treating
all sockets as UV_NAMED_PIPE, use getsockopt() and
getsockaddr() to determine if the socket is an AF_UNIX
stream (in which case return UV_NAMED_PIPE), or an AF_INET
stream (in which case return UV_TCP), or an AF_INET datagram
socket (in which case return UV_UDP).
Additionally, currently all other file descriptor types are
squelched to the UV_FILE type. Instead, only file descriptors
that are marked as regular files are treated as UV_FILE. All
other types (such as directories, character and block devices)
are now treated as UV_UNKNOWN_HANDLE.
Replace `void f()` with `void f(void)`; the former means "a function
that takes any number of arguments, including none" while the latter
is what is actually intended: a function taking no arguments.
The first form also isn't strictly conforming ANSI/ISO C.
`#if FOO` (where FOO is undefined) is a legal construct in C89 and C99
but gcc, clang and sparse complain loudly about it at higher warning
levels.
Squelch those warnings. Makes the code more consistent as well.
Fixes a bug where timers expire prematurely when the following
conditions hold:
a) libuv first spends some time blocked in the platform poll function
b) a callback then calls uv_timer_start()
Cause: uv_timer_start() uses an out-of-date loop->time in its
'when should the timer callback run?' calculations.
Solution: Update loop->time before invoking any callbacks.
Fixes#678.
This commit renames the various uv_hrtime() implementations to uv__hrtime().
Libuv uses the high-res timer internally in performance-critical code paths.
Calling the non-public version avoids going through the PLT when libuv is
compiled as a shared object.
The exported uv_hrtime() now has a single definition in src/unix/core.c that
calls uv__hrtime().
A future optimization is to lift the uv__hrtime() declarations into header
files so they can be inlined at the call sites. Then again, linking with -flto
should accomplish the same thing.
Introduced in 0db3274f but no longer necessary; uv__write() no longer
runs when the handle has been closed. Write callbacks receive a special
status code that informs them that the handle has been closed.
Wake up the event loop with uv_async_send() when a request is cancelled.
Ensures the done_cb is run on the next tick of the event loop.
Not sending a wakeup signal results in the done_cb not getting called until
another request completes, which may be a long time coming when it's the only
request in the queue or when other requests are executing long-running jobs.
Fixes#669.
A common way to check if a uv_fs_t request failed is to check that
req->errorno != 0.
With uv_fs_sendfile(), when the sendfile() syscall fails, req->errorno is set
to (for example) ENOTSOCK, even when the emulation code path succeeds.
Zero errno before the call to uv__fs_sendfile_emul() to prevent that from
happening.
