If an http response has an 'end' handler that throws, then the socket
will never be released back into the pool.
Granted, we do NOT guarantee that throwing will never have adverse
effects on Node internal state. Such a guarantee cannot be reasonably
made in a shared-global mutable-state side-effecty language like
JavaScript. However, in this case, it's a rather trivial patch to
increase our resilience a little bit, so it seems like a win.
There is no semantic change in this case, except that some event
listeners are removed, and the `'free'` event is emitted on nextTick, so
that you can schedule another request which will re-use the same socket.
From the user's point of view, there should be no detectable difference.
Closes#5107
The tests did not agree with the test comments. Tests first and second
were both testing the !state.reading case. Now second tests the
state.reading && state.length case.

In cases where a stream may have data added to the read queue before the
user adds a 'readable' event, there is never any indication that it's
time to start reading.
True, there's already data there, which the user would get if they
checked However, as we use 'readable' event listening as the signal to
start the flow of data with a read(0) call internally, we ought to
trigger the same effect (ie, emitting a 'readable' event) even if the
'readable' listener is added after the first emission.
To avoid confusing weirdness, only the *first* 'readable' event listener
is granted this privileged status. After we've started the flow (or,
alerted the consumer that the flow has started) we don't need to start
it again. At that point, it's the consumer's responsibility to consume
the stream.
Closes#5141
A llvm/clang bug on Darwin ia32 makes these tests fail 100% of
the time. Since no one really seems to mind overly much, and we
can't reasonably fix this in node anyway, just accept both types
of NaN for now.
Calling `this.pair.encrypted._internallyPendingBytes()` before
handling/resetting error will result in assertion failure:
../src/node_crypto.cc:962: void node::crypto::Connection::ClearError():
Assertion `handle_->Get(String::New("error"))->BooleanValue() == false'
failed.
see #5058
Since _tickCallback and _tickDomainCallback were both called from
MakeCallback, it was possible for a callback to be called that required
a domain directly to _tickCallback.
The fix was to implement process.usingDomains(). This will set all
applicable functions to their domain counterparts, and set a flag in cc
to let MakeCallback know domain callbacks always need to be checked.
Added test in own file. It's important that the test remains isolated.
It's possible to read multiple messages off the parent/child channel.
When that happens, make sure that recvHandle is cleared after emitting
the first message so it doesn't get emitted twice.
Commit f53441a added crypto.getCiphers() as a function that returns the
names of SSL ciphers.
Commit 14a6c4e then added crypto.getHashes(), which returns the names of
digest algorithms, but that creates a subtle inconsistency: the return
values of crypto.getHashes() are valid arguments to crypto.createHash()
but that is not true for crypto.getCiphers() - the returned values are
only valid for SSL/TLS functions.
Rectify that by adding tls.getCiphers() and making crypto.getCiphers()
return proper cipher names.
In process#send() and child_process.ChildProcess#send(), use 'utf8' as
the encoding instead of 'ascii' because 'ascii' mutilates non-ASCII
input. Correctly handle partial character sequences by introducing
a StringDecoder.
Sending over UTF-8 no longer works in v0.10 because the high bit of
each byte is now cleared when converting a Buffer to ASCII. See
commit 96a314b for details.
Fixes#4999 and #5011.
Throw a TypeError if size > 0x3fffffff. Avoids the following V8 fatal
error:

Fixes#5126.
The stall is exposed in the test, though the test itself asserts before
it stalls.
The test is constructed to replicate the stalling state of a complex
Passthrough usecase since I was not able to reliable trigger the stall.
Some of the preconditions for triggering the stall are:
* rs.length >= rs.highWaterMark
* !rs.needReadable
* _transform() handler that can return empty transforms
* multiple sync write() calls
Combined this can trigger a case where rs.reading is not cleared when
further progress requires this. The fix is to always clear rs.reading.
Before this patch calling `socket.setTimeout(0xffffffff)` will result in
signed int32 overflow in C++ which resulted in assertion error:
Assertion failed: (timeout >= -1), function uv__io_poll, file
../deps/uv/src/unix/kqueue.c, line 121.
see #5101
Also, set paused=false *before* calling resume(). Otherwise,
there's an edge case where an immediately-emitted chunk might make
it call pause() again incorrectly.
Commit a804347 makes fs function rethrow errors when the callback is
omitted. While the right thing to do, it's a change from the old v0.8
behavior where such errors were silently ignored.
To give users time to upgrade, temporarily disable that and replace it
with a function that warns once about the deprecated behavior.
Close#5005
This solves the problem of calling `readable.pipe(writable)` after the
readable stream has already emitted 'end', as often is the case when
writing simple HTTP proxies.
The spirit of streams2 is that things will work properly, even if you
don't set them up right away on the first tick.
This approach breaks down, however, because pipe()ing from an ended
readable will just do nothing. No more data will ever arrive, and the
writable will hang open forever never being ended.
However, that does not solve the case of adding a `on('end')` listener
after the stream has received the EOF chunk, if it was the first chunk
received (and thus, length was 0, and 'end' got emitted). So, with
this, we defer the 'end' event emission until the read() function is
called.
Also, in pipe(), if the source has emitted 'end' already, we call the
cleanup/onend function on nextTick. Piping from an already-ended stream
is thus the same as piping from a stream that is in the process of
ending.
Updates many tests that were relying on 'end' coming immediately, even
though they never read() from the req.
Fix#4942
In the function that pre-emptively fills the Readable queue, it relies
on a recursion through:
stream.push(chunk) ->
maybeReadMore(stream, state) ->
if (not reading more and < hwm) stream.read(0) ->
stream._read() ->
stream.push(chunk) -> repeat.
Since this was only calling read() a single time, and then relying on a
future nextTick to collect more data, it ends up causing a nextTick
recursion error (and potentially a RangeError, even) if you have a very
high highWaterMark, and are getting very small chunks pushed
synchronously in _read (as happens with TLS, or many simple test
streams).
This change implements a new approach, so that read(0) is called
repeatedly as long as it is effective (that is, the length keeps
increasing), and thus quickly fills up the buffer for streams such as
these, without any stacks overflowing.
so `ee.emit('error')` doesn't throw when domains are active
create an empty error only when handled by a domain
test for when no error is provided to an error event
Fix#4948
This adds a check before setting the incoming parser
to null. Under certain circumstances it'll already be set to
null by freeParser().
Otherwise this will cause node to crash as it tries to set
null on something that is already null.
When calling setImmediate with extra arguments the this keyword in the
callback would refer to the global object, but when not calling
setImmediate with extra arguments this would refer to the returned
handle object.
This commit fixes that inconsistency so its always set handle object.
The handle object was chosen for performance reasons.
Also, this seems to occasionally cause some annoying file-locking
errors in Windows. Not sure if this is the best fix, but it seems
to make the warnings go away in that spot.
If you call z.flush();z.write('foo'); then it would try to write 'foo'
before the flush was done, triggering an assertion in the zlib binding.
Closes#4950
Consider the following example:
console.log(Buffer('ú').toString('ascii'));
Before this commit, the contents of the buffer was used as-is and hence it
prints 'ú'.
Now, it prints 'C:'. Perhaps not much of an improvement but it conforms to what
the documentation says it does: strip off the high bits.
Fixes#4371.

child.send can send net servers and sockets. Now that we have support
for dgram clusters this functionality should be extended to include
dgram sockets.
This adds the following to HTTP:
* server.setTimeout(msecs, callback)
Sets all new connections to time out after the specified time, at
which point it emits 'timeout' on the server, passing the socket as an
argument.
In this way, timeouts can be handled in one place consistently.
* req.setTimeout(), res.setTimeout()
Essentially an alias to req/res.socket.setTimeout(), but without
having to delve into a "buried" object. Adds a listener on the
req/res object, but not on the socket.
* server.timeout
Number of milliseconds before incoming connections time out.
(Default=1000*60*2, as before.)
Furthermore, if the user sets up their own timeout listener on either
the server, the request, or the response, then the default behavior
(destroying the socket) is suppressed.
