Don't emit a 'connect' event on sockets that are handed off to
net.Server 'connection' event listeners.
1. It's superfluous because the connection has already been established
at that point.
2. The implementation is arguably wrong because the event is emitted on
the same tick of the event loop while the rule of thumb is to always
emit it on the next one.
This has been tried before in commit f0a440d but was reverted again in
ede1acc because the change was incomplete (at least one test hadn't
been updated).
Fixes#1047 (again).
Previously, we were only destroying sockets on end if their readable
side had already been ended. This causes a problem for non-readable
streams, since we don't expect to ever see an 'end' event from those.
Treat the lack of a 'readable' flag the same as if it was an ended
readable stream.
Fix#4751
Let ECONNRESET network errors bubble up so clients can detect them.
Commit c4454d2e suppressed and turned them into regular end-of-stream
events to fix the then-failing simple/test-regress-GH-1531 test. See
also issue #1571 for (scant) details.
It turns out that special handling is no longer necessary. Remove the
special casing and let the error bubble up naturally.
pummel/test-https-ci-reneg-attack and pummel/test-tls-ci-reneg-attack
are updated because they expected an EPIPE error code that is now an
ECONNRESET. Suppression of the ECONNRESET prevented the test from
detecting that the connection has been severed whereupon the next
write would fail with an EPIPE.
Fixes#1776.
This commit breaks simple/test-stream2-stderr-sync. Need to figure out
a better way, or just accept that `(function W(){stream.write(b,W)})()`
is going to be noisy. People should really be using the `'drain'` event
for this use-case anyway.
This reverts commit 02f7d1bfd8.
Always defer the _write callback. The optimization here was only
relevant in some oddball edge cases that we don't actually care about.
Our benchmarks confirm that just always deferring the Socket._write cb
is perfectly fine to do, and in some cases, even slightly more
performant.
TCPWrap::Initialize() and PipeWrap::Initialize() should be called before
any data will be read from received socket. But, because of lazy
initialization of these bindings, Initialize() method isn't called.
Init bindings manually upon socket receiving.
See #4669
Keeping list of all sockets that were sent to child process causes memory
leak and thus unacceptable (see #4587). However `server.close()` should
still work properly.
This commit introduces two options:
* child.send(socket, { track: true }) - will send socket and track its status.
You should use it when you want to receive `close` event on sent sockets.
* child.send(socket) - will send socket without tracking it status. This
performs much better, because of smaller number of RTT between master and
child.
With both of these options `server.close()` will wait for all sent
sockets to get closed.

socket.readyState, .readable, and .writable behavior changed as
a result of the new streaming interfaces. Updated to be backwards
compatible with current API and adds regression test.

This commit reverts the following commits (in reverse chronological order):
74d076c errnoException must be done immediately
ddb02b9 net: support Server.listen(Pipe)
085a098 cluster: do not use internal server API
d138875 net: lazy listen on handler
Commit d138875 introduced a backwards incompatible change that broke the
simple/test-net-socket-timeout and simple/test-net-lazy-listen tests - it
defers listening on the target port until the `net.Server` instance has at
least one 'connection' event listener.
The other patches had to be reverted in order to revert d138875.
Fixes#3832.
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.
Passing a non-buffer or non-string argument to Socket.prototype.write triggered
an assert:
Assertion failed: (Buffer::HasInstance(args[0])), function Write,
file ../src/stream_wrap.cc, line 289.
Fixes#2532.
This makes it so that the stdin TTY-wrap stream gets ref'ed on
.resume() and unref'ed on .pause()
The semantics of the names "pause" and "resume" are a bit weird, but the
important thing is that this corrects an API change from 0.4 -> 0.6
which made it impossible to read from stdin multiple times, without
knowing when it might end up being closed. If no one has it open, this
lets the process die naturally.

Don't allow `socket.destroy()` to run twice. The self-destruct sequence itself
is idempotent but it makes the 'close' and 'error' events fire more than once,
which may confuse listeners.
Fixes#2223.
Just a syntactic sugar for doing, for example:
var server = net.createServer(function (c) {
c.end('goodbye, cruel world!\r\n');
server.close().on('close', function () {
console.log('really, goodbye!');
});
}).listen(1337);
Fixes#1922.
This commit fixes two bugs in the handling of write requests when the connect()
call is still in progress.
1. The deferred write request's size was counted twice towards `.bytesWritten`.
2. The callback was not called. After connecting, `Socket.write()` was called
with three arguments (data, encoding, cb) but it ignored the third argument.
Coincidentally fixes test/simple/test-net-connect-buffer.js.
Only register once for listening when passing a callback to Server.listen(),
this prevents servers recycled using close() from invoking the callback when
Server.listen() is called later.
Sockets emitted by the 'connection' event are always connected, having
them emit the 'connect' event makes no sense. It only confused people,
as it's not clear if you have to listen to 'connect' or not.
That try..catch block was also very scary. It would silently swallow
exceptions in 'connect' listeners and destroy the socket. Makes no
sense.
Fixes#1047.
setImplementationMethods checks the type of a socket and defines different
behavior based on the type, so auto detect it if type not implicitly
specified.
Change to end() behavior in 33c339 was breaking it. end() should wait for
connection before dumping. Changed test-net-connect-timeout to use destroy()
instead.
Users too often would forget to add
socket.on('end', function () {
socket.end();
});
Which is a mistake. Therefore we default to this behavior and
only optionally let people handle the 'end' case themselves.
When a server hit EMFILE it would continue to try to accept new connections
from the queue. This patch introduces a timeout of one second where it will
stop trying to accept new files. After the second is over it tries again.
This is a rather serious bug that has been effecting many highly concurrent
programs. It was introduced in 4593c0, version v0.2.0.
TODO: A test for this situation. Currently I test it like this
termA% cd projects/node
termA% ulimit -n 256
termA% ./node benchmark/idle_server.js
termB% cd projects/node
termB% ./node benchmark/idle_clients.js
And watch how the server process behaves.
- Without this, recvMsg can be invoked before the event emitter gets a
chance to run. In this case, recvMsg.fd will be overwritten and the
original caller can end up emitting null.
This is needed in case the provided socket is not the default 'tcp4' type
(i.e. and needs different read/write/etc methods). With this patch, one can
call listenFD(sock, 'unix') to bind to existing UNIX domain sockets.
Now that FD passing is in master, it'd be great to be able to use a received
socket (which has already had bind(2) and listen(2) called on it) to fire up a
new net.Server instance. This patch adds a net.Server.listenFD() method which
will start up the accept watcher on the provided FD.
a) create a layer of indirection in net.Stream to allow swapping in
different read/write implementations and
b) emit an 'fd' event when file descriptors are received over a UNIX pipe,
as finally as a tangential benefit
c) remove a bunch of conditionals from the primary codepaths for
ease-of-reading.
There is a difference between errors which happen to a socket - like
receiving EPIPE - an exceptional situation but ultimately okay and the
situation where code throws in a callback - which is not okay.
Fixes test/simple/test-http-exceptions.js
TODO: explain this in docs.
- setTimeout should active the timeout too. (test-net-set-timeout tests
this.)
- 'timeout' event is not automatically followed by an 'error' event. That
is the user is now responsible for destroying the stream if there is an
idle timeout.
When making a TCP connection, readyState returns 'opening' while resolving
the host. However between the resolving period and the establishing a
connection period, it would return 'closed'. This fixes it.
This change also ensures that the socket is closed before the 'end' event is
emitted in the case that the socket was previously shutdown.
