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.
The documentation in uv.h states that the status argument to the
uv_getaddrinfo() callback is either 0 or -1 but uv-unix actually
passed it the addrinfo error code. Rectify that and add a regression
test.
Fixes#754.
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.
If the uv_getaddrinfo_t handle is owned by its
data pointer, deleting the data in the callback
could cause uv_getaddrinfo_done to call freeaddrinfo
on an invalid pointer.
This patch also fixes#155. Since we no longer
memset clear the uv_getaddrinfo_t, the user can
now set the `uv_getaddrinfo_t->data` field without
problems.
