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(...);
}
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).
Useful to know when the the event loop is empty, this can't be done with
uv_run() without possibly blocking, or running some events (which might
empty the event loop as a side-effect).
`uv_try_write(stream, buf, size)` acts like `uv_write()`,
but without queueing actual write until UV_POLLOUT (or IOCP completion).
This is useful for doing writes using on-stack `uv_write_t` requests.
fix#1025
When using configure, there are situations where libuv will attempt
to build uv-dtrace.h, even if it is configured with --disable-dtrace.
For example, if libuv is first configured with dtrace enabled, then
built, the .deps files will contain references to include/uv-dtrace.h.
After a make clean and configure --disable-dtrace, the build will still
attempt to create include/uv-dtrace.h and fail. make will see the
dependency reference (which survives the make clean), use the rule
(which is always added to the Makefile), and fail since DTRACE is not
defined.
This commit protects the rules to make uv-dtrace.h with the proper
conditionals to ensure the rules are not written if --disable-dtrace
is chosen.
Fix#963.
Fix a bug that was introduced in commit 3ee4d3f ("unix, windows:
return error codes directly") and add a regression test for good
measure.
Hat tip to Fedor for pointing out the issue.
Fixes#1007.
Work around an epoll quirk where it sometimes reports just the EPOLLERR
or EPOLLHUP event. In order to force the event loop to move forward,
we merge in the read/write events that the watcher is interested in;
uv__read() and uv__write() will then deal with the error or hangup in
the usual fashion.
Fixes#982.
Load the required symbols at run-time rather than linking against the
CoreFoundation (and CoreServices and ApplicationServices) frameworks
at build time.
Should make integration easier for people that bundle libuv with their
own projects because they no longer have to replicate magic -framework
incantations in their top-level build system.
Squelches (justified) warnings with automake 1.14.
Object files are built in subdirectories now so fix up the dtrace
postprocessing step to scan for *.lo files in said subdirectories.
Fixes#866.
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.
Switch to the build tool everyone loves to hate. The Makefile has
served us well over the years but it's been acquiring more and more
features that autotools gives us for free, like easy static+shared
library building, sane install targets, and so on.
This commit drops MinGW support. If there is demand for it, we'll
re-add it.
