This fixes the problem that calling pause() on a socket would not
actually prevent 'data' events from being emitted. It also replaces
the existing test by a more elaborate one.
Ref: #3118
Problem: calling `server.listen()` (no port) on a net.Server triggered the
following libuv assertion:
node: ../deps/uv/src/unix/stream.c:406: uv__write: Assertion `fd_to_send >= 0'
failed.
Cause: uv_tcp_t handles are lazily initialized. Omitting the port made the
handle get initialized even more lazily. Too lazily - it wasn't initialized
when the handle was sent over to the child process.
Solution: implicitly bind to a random port in listen() when the port number
is omitted, it forces the handle to initialize. This is not a change in
behavior, listen() has always been identical to listen(0).
Fixes#3325.
Fix#3455.
The remoteAddress and remotePort properties are
dynamically retrieved from _getpeername().
While _getpeername() checks if the _handle is
null, it is also possible for the tcp_wrapped
_handle.getpeername() to return null on error.
Such a condition happens when the remote closes
and one of these properties is accessed before
_handle is set to null.
This implements server.listen({ fd: <filedescriptor> }). The fd should
refer to an underlying resource that is already bound and listening, and
causes the new server to also accept connections on it.
Not supported on Windows. Raises ENOTSUP.
The server 'close' event was emitted before the last client 'close' event. Not
exactly fatal but potentially confusing.
Before this commit the order looked something like [client, server, client],
now it looks like [client, client, server].
See #3340 for more details.
In case a worker would spawn a new subprocess with process.env, NODE_UNIQUE_ID
would have been a part of the env. Making the new subprocess believe it is a
worker, this would result in some confusion if the subprocess where to listen to
a port, since the server handle request would then be relayed to the worker.
This patch removes the NODE_UNIQUE_ID flag from process.env on startup so any
subprocess spawned by a worker is a normal process with no cluster stuff.
child_process.fork() support sending native hander object, this patch add support for sending
net.Server and net.Socket object by converting the object to a native handle object and back
to a useful object again.
Note when sending a Socket there was emitted by a net Server object, the server.connections
property becomes null, because it is no longer possible to known when it is destroyed.
This commit fixes a bug where the cluster module failed to propagate EADDRINUSE
errors.
When a worker starts a (net, http) server, it requests the listen socket from
its master who then creates and binds the socket.
Now, OS X and Windows don't always signal EADDRINUSE from bind() but instead
defer the error until a later syscall. libuv mimics this behaviour to provide
consistent behaviour across platforms but that means the worker could end up
with a socket that is not actually bound to the requested addresss.
That's why the worker now checks if the socket is bound, raising EADDRINUSE if
that's not the case.
Fixes#2721.
