Debug build failed on mingw32 because CRT assertion disable code was stubbed out.
Replace __declspec(thread) with UV_THREAD_LOCAL which is defined as __thread on GCC.
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(...);
}
If passed and invalid FD, _get_osfhandle() sets an error code
through errno, not _doserrno. Hence we need to use
SET_REQ_WIN32_ERROR insted of SET_REQ_RESULT.
In debug builds, _get_osfhandle() also raises a superfluous
assert. I implemented a wrapper that disables all asserts
around the call to _get_osfhandle().
This fixes node.js unit tests test-fs-read-stream.js and
test-listen-fd-ebadf.js.
Passing or returning structs as values makes life hard for people that
work with libuv through a foreign function interface. Switch to a
pointer-based approach.
Fixes#684.
This commit changes the libuv API to return error codes directly rather
than storing them in a loop-global field.
A code snippet like this one:
if (uv_foo(loop) < 0) {
uv_err_t err = uv_last_error(loop);
fprintf(stderr, "%s\n", uv_strerror(err));
}
Should be rewritten like this:
int err = uv_foo(loop);
if (err < 0)
fprintf(stderr, "%s\n", uv_strerror(err));
The rationale for this change is that it should make creating bindings
for other languages a lot easier: dealing with struct return values is
painful with most FFIs and often downright buggy.
This patch adds the `uv_stream_set_blocking` API which makes all
uv_write calls to that stream blocking. It currently only works for
pipes, on windows.
We use GetQueuedCompletionStatus(Ex) to sleep the thread until the next
timer expires (provided that no other events happen before that).
However after waking up from a sleep the GetTickCount() return value may
not immediately reflect that some time has passed. This happens because
gqcs can sometimes sleep for periods shorter than the GetTickCount clock
resulution. This patch changes time tracking so the amount of time
waited by gqcs is taken into account.
This has the following advantages:
* Excessive loop iterations are avoided.
* Small timeouts are fired more precisely.
* The `loop-stop` test that used to be flaky on Windows now passes
consistently.
No longer explictly check wheter an IPv6 stack is present when the user
tries to use IPV6 sockets. Instead realy on the operating system
to report the lack of protocol support via appropriate error messages.
Formerly spawn errors would be reported as a message printed to the
process' stderr, to match unix behaviour. Unix has now been fixed to
be more sensible, so this hack can now be removed.
This also fixes a race condition that could occur when the user closes
a process handle before the exit callback has been made.
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.
Not needed anymore now that support for isolates has been removed from Node.
