A child process created with .fork() needed to call `process.exit()` explicitly
because the communication channel with the parent kept the event loop alive.
Fix that by only ref'ing the channel when there are 'message' event listeners.
Fixes#3799.
With this patch the IPC socket is no longer available in the
ChildProcess.stdio array. This shouldn't be very problematic, since
this socket was effectively non-functional; it would never emit any
events.
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.
Previously, a command with a short stdio array would result in the child's
stdout and stderr objects set to null. For example:
var c = child_process.spawn(cmd, args, {stdio: ['pipe']});
// results in c.stdout === null.
The expected behavior is the above line functioning the same as this one:
var c = child_process.spawn(cmd, args, {stdio: ['pipe', null, null]});
// provides correct (non-null) c.stdout; as does the above, after this fix.

* When the process is already dead, but the `exit` signal wasn't raised
yet, the ESRCH error should be ignored.
* When an invalid signal is specified, kill() should throw.
* Like process.kill(), child_process.kill() now preserves a `0` signal
which can be used to check the liveliness of the child process.
* process.kill() and child_process.kill() will now return true if the
signal was actually delivered, and false otherwise.
* When an `exec`-ed process is automatically killed because a time or
buffer limit is exceeded, and the kill() fails, this error should be
reported through the `exec` callback.
Fixes: #3409
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.
Currently, a child process does not emit the 'exit' event until 'close' events
have been received on all three of the child's stdio streams. This change makes
the child object emit 'exit' when the child exits, and a new 'close' event when
all stdio streams are closed.
It was decided that the performance benefits that isolates offer (faster spin-up
times for worker processes, faster inter-worker communication, possibly a lower
memory footprint) are not actual bottlenecks for most people and do not outweigh
the potential stability issues and intrusive changes to the code base that
first-class support for isolates requires.
Hence, this commit backs out all isolates-related changes.
Good bye, isolates. We hardly knew ye.
When using isolate the .fork would break because it had
no .disconnect method. This remove the exit handler there
would call .disconnect since it was not required.
It also change .disconnect to throw if the channel is closed,
this was not possible before because .disconnect would be called
twice.
This is mostly working, but not completely ideal for two reasons.
1. Rather than emitting an error on the ChildProcess object when the
setgid/setuid fails, it is simply printing the error to stderr and
exiting. The same happens with the cwd, so that's not completely
terrible.
2. I don't have a good test for this. It fails with an EPERM if you try
to change the uid or gid as a non-root user.
Originally added in commit 078a48a9, this code dealt with an optional
env parameter that was passed to `exec`. The parameter was removed, but
this code was left. As it serves no purpose, removing it.
