When sending a socket to a child process via IPC pipe,
`child_process.js` picks a raw UV handle from `_handle` property, sends
it, and assigns `null` to the property. Sending the same socket twice
was resulting in a runtime error, since we weren't handling the empty
`_handle` case.
In case of `null` `_handle` we should send just a plain text message
as passed it was passed to `.send()` and ignore the handle, letting
users handle such cases themselves instead of throwing the error at
runtime.
fix#5469
If two timers run on the same tick, and the first timer uses a domain,
and then catches an exception and disposes of the domain, then the
second timer never runs. (And even if the first timer does not dispose
of the domain, the second timer could run under the wrong domain.)
This happens because timer.js uses "process.nextTick()" to schedule
continued processing of the timers for that tick. However, there was
an exception inside a domain, then "process.nextTick()" runs under
the domain of the first timer function, and will do nothing if
the domain has been disposed.
To avoid this, we temporarily save the value of "process.domain"
before calling nextTick so that it does not run inside any domain.
This makes it so that the user may pass in a
`createConnection()` option, and they don't have
to pass `agent: false` at the same time.
Also adding a test for the `createConnection` option,
since none was in place before.
See #7014.
Ensure that the behavior of `assert.deepEqual` does not depend on
argument ordering when comparing an `arguments` object with a
non-`arguments` object.
The reason this wasn't working was because after restart, when restoring
breakpoints the scripts wasn't loaded, so the breakpoint.script was
undefined. As a fix I added another check to use breakpoint.scriptReq
instead of breakpoint.script, which is the same except when the
breakpoint is a function.

Don't use argument as callback if it's not a valid callback function.
Throw a valid exception instead explaining the issue. Adds to #7070
("DNS — Throw meaningful error(s)").
Even if stdio streams are opened as file streams, we should not ever try
to close them. This could be accomplished by passing `autoClose: false`
in options on their creation.
Spawn's arguments were documented to be optional, as they are for the
other similar child_process APIs, but the code was missing. Result was
`child_process.spawn('node', {})` errored when calling slice() on an
Object, now it behaves as the documentation said it would.
domain.create().exit() should not clear the domain stack if the domain
instance does not exist within the stack.

If a write is above the highWaterMark, _write still manages to
fully send it synchronously, _writableState.length will be adjusted down
to 0 synchronously with the write returning false, but 'drain' will
not be emitted until process.nextTick.
If another small write which is below highWaterMark is issued before
process.nextTick happens, _writableState.needDrain will be reset to false,
and the drain event will never be fired.
So we should check needDrain before setting it up, which prevents it
from inproperly resetting to false.
NOTE: Also removed `.receivedShutdown` method of `Connection` it wasn't
documented anywhere, and was rewritten with `true` after receiving
`close_notify`.
fix#6638
When calling `encOut` in loop, `maybeInitFinished()` may invoke
`clearOut`'s loop, leading to the writing of interleaved data
(encrypted and cleartext) into the one shared pool.
Move `maybeInitFinished()` out of the loop and add assertion for
future.
Check that `listeners` is actually an array before trying to manipulate it
because it won't be if no regular event listeners have been registered yet
but there are 'removeListener' event listeners.
Emitting an event within a `EventEmitter#once` callback of the same
event name will cause subsequent `EventEmitter#once` listeners of the
same name to be called multiple times.
var emitter = new EventEmitter();
emitter.once('e', function() {
emitter.emit('e');
console.log(1);
});
emitter.once('e', function() {
console.log(2);
});
emitter.emit('e');
// Output
// 2
// 1
// 2
Fix the issue, by calling the listener method only if it was not
already called.
Fix invalid `hasOwnProperty` function usage.
For example, before in the REPL:
```
> Ar<Tab>
Array
Array ArrayBuffer
```
Now:
```
> Ar<Tab>
Array
ArrayBuffer
```
Fixes#6255.
Closes#6498.
If a client sends a lot more pipelined requests than we can handle, then
we need to provide backpressure so that the client knows to back off.
Do this by pausing both the stream and the parser itself when the
responses are not being read by the downstream client.
Backport of 085dd30
Destroying the TLS session implies destroying the underlying socket but
before this commit, that was done with net.Socket#destroy() rather than
net.Socket#destroySoon(). The former closes the connection right away,
even when there is still data to write. In other words, sometimes the
final TLS record got truncated.
Fixes#6107.
fs.truncate() and its synchronous sibling are implemented in terms of
open() + ftruncate(). Unfortunately, it opened the target file with
mode 'w' a.k.a. 'write-only and create or truncate at open'.
The subsequent call to ftruncate() then moved the end-of-file pointer
from zero to the requested offset with the net result of a file that's
neatly truncated at the right offset and filled with zero bytes only.
This bug was introduced in commit 168a5557 but in fairness, before that
commit fs.truncate() worked like fs.ftruncate() so it seems we've never
had a working fs.truncate() until now.
Fixes#6233.
Otherwise the data ends up "on the wire" twice, and
switching between consuming the stream using `ondata`
vs. `read()` would yield duplicate data, which was bad.
The NPN protocols was set on `require('tls')` or `global` object instead
of being a local property. This fact lead to strange persistence of NPN
protocols, and sometimes incorrect protocol selection (when no NPN
protocols were passed in client options).
fix#6168
Since the encoding is no longer relevant once it is decoded to a Buffer,
it is confusing and incorrect to pass the encoding as 'utf8' or whatever
in those cases.
Closes#6119
`maybeInitFinished()` can emit the 'secure' event which
in turn destroys the connection in case of authentication
failure and sets `this.pair.ssl` to `null`.
If such condition appeared after non-empty read - loop will continue
and `clearOut` will be called on `null` object instead of
`crypto::Connection` instance. Resulting in the following assertion:
ERROR: Error: Hostname/IP doesn't match certificate's altnames
Assertion failed: handle->InternalFieldCount() > 0
fix#5756
In this situation:
writable.on('error', handler);
readable.pipe(writable);
writable.removeListener('error', handler);
writable.emit('error', new Error('boom'));
there is actually no error handler, but it doesn't throw, because of the
fix for stream.once('error', handler), in 23d92ec.
Note that simply reverting that change is not valid either, because
otherwise this will emit twice, being handled the first time, and then
throwing the second:
writable.once('error', handler);
readable.pipe(writable);
writable.emit('error', new Error('boom'));
Fix this with a horrible hack to make the stream pipe onerror handler
added before any other userland handlers, so that our handler is not
affected by adding or removing any userland handlers.
Closes#6007.
Add range checks for the offset, length and port arguments to
dgram.Socket#send(). Fixes the following assertion:
node: ../../src/udp_wrap.cc:264: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`offset < Buffer::Length(buffer_obj)' failed.
And:
node: ../../src/udp_wrap.cc:265: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`length <= Buffer::Length(buffer_obj) - offset' failed.
Interestingly enough, a negative port number was accepted until now but
silently ignored. (In other words, it would send the datagram to a
random port.)
This commit exposed a bug in the simple/test-dgram-close test which
has also been fixed.
This is a back-port of commit 41ec6d0 from the master branch.
Fixes#6025.
On windows, libuv will immediately make a `ReadConsole` call (in the
thread pool) when a 'flowing' `uv_tty_t` handle is switched to
line-buffered mode. That causes an immediate issue for some users,
since libuv can't cancel the `ReadConsole` operation on Windows 8 /
Server 2012 and up if the program switches back to raw mode later.
But even if this will be fixed in libuv at some point, it's better to
avoid the overhead of starting work in the thread pool and immediately
cancelling it afther that.
See also f34f1e3, where the same change is made for the opposite
flow, e.g. move `resume()` after `_setRawMode(true)`.
Fixes#5927
This is a backport of dfb0461 (see #5930) to the v0.10 branch.
If an error listener is added to a stream using once() before it is
piped, it is invoked and removed during pipe() but before pipe() sees it
which causes it to be emitted again.
Fixes#4155#4978
Before this commit, events were set to undefined rather than deleted
from the EventEmitter's backing dictionary for performance reasons:
`delete obj.key` causes a transition of the dictionary's hidden class
and that can be costly.
Unfortunately, that introduces a memory leak when many events are added
and then removed again. The strings containing the event names are never
reclaimed by the garbage collector because they remain part of the
dictionary.
That's why this commit makes EventEmitter delete events again. This
effectively reverts commit 0397223.
Fixes#5970.
