Problem 1: If stream.push() triggers a 'readable' event, and the user
calls `read(n)` with some n > the highWaterMark, then the push() will
return false (indicating that they should not push any more), but no
future 'readable' event is coming (because we're above the
highWaterMark).
Solution: return true from push() when needReadable is set.
Problem 2: A read(n) for n != 0, after the stream had encountered an
EOF, would not trigger the 'end' event if the EOF was pushed in
synchronously by the _read() function.
Solution: Check for ended in stream.read() and schedule an end event if
the length now equals 0.
Fix#4585
Improved assert check order of execution and added additional checks on
parameters to ensure no bad values make it through (e.g. negative offset
values).
Improvements:
* floating point operations are approx 4x's faster
* Now write quiet NaN's
* all read/write on floating point now done in C, so no more need for
lib/buffer_ieee754.js
* float values have more accurate min/max value checks
* add additional benchmarks for buffers read/write
* created benchmark/_bench_timer.js which is a simple library that
can be included into any benchmark and provides an intelligent tracker
for sync and async tests
* add benchmarks for DataView set methods
* add checks and tests to make sure offset is greater than 0
There was previously an assert() in there, but this part of the code is
so high-volume that the added cost made a measurable dent in http_simple.
Just checking inline is fine, though, and prevents a lot of potential
hazards.
Say that a stream's current read queue has 101 bytes in it, and the
underlying resource has ended (ie, reached EOF).
If you do something like this:
stream.read(100); // leave a byte behind
stream.read(0); // read(0) for some reason
then the read(0) will get 0 from the howMuchToRead function. Since the
stream was ended, this was incorrectly treating the 0 as a "there is no
more in the buffer", and emitting 'end' before that last byte was read.
Why have the read(0) in the first place? We do this in some cases to
trigger the last few bytes of a net socket (such as a child process's
stdio pipes). This was causing issues when piping a `git archive` job
to a file: the resulting tarball was incomplete, because it occasionally
was not getting the last chunk.
Fix the following exception:
http.js:974
this._httpMessage.emit('close');
^
TypeError: Cannot call method 'emit' of null
at Socket.onServerResponseClose (http.js:974:21)
at Socket.EventEmitter.emit (events.js:124:20)
at net.js:421:10
at process._tickCallback (node.js:386:13)
at process._makeCallback (node.js:304:15)
Fixes#4586.
This also slightly changes the semantics, in that a 'readable'
event may be triggered by the first write() call, even if a
user has not yet called read().
This happens because the Transform _write() handler is calling
read(0) to start the flow of data. Technically, the new behavior
is more 'correct', since it is more in line with the semantics
of the 'readable' event in other streams.
When switching into compatibility mode by setting `data` event listener,
`_read()` method will be called immediately. If method implementation
invokes callback in the same tick - all emitted `data` events will be
discarded, because `data` listener wasn't set yet.
Raise a TypeError when the argument to send() or sendto() is anything
but a Buffer.
Fixes the following assertion:
$ node -e 'require("dgram").createSocket("udp4").send("BAM")'
node: ../../src/udp_wrap.cc:220: static v8::Handle<v8::Value>
node::UDPWrap::DoSend(const v8::Arguments&, int): Assertion
`Buffer::HasInstance(args[0])' failed.
Aborted (core dumped)
Fixes#4496.
Allows for arbitrary path to executable spawned using `fork`. This
fixes some issues around running multiple versions of node with workers
and allows arbitrary IPC with compatible executables.
Fixes#3248.
In JS, the expression ".1" is a floating point number. Issue 4268 concerns the
REPL interpreting floating point numbers that lead with a "." as keywords. The
original bugfix worked for this specific case but not for the general case:
var x = [
.1,
.2,
.3
];
The attached change and test (`.1+.1` should be `.2`) fix the bug.
Closes#4513.
Don't give names of built-in libraries special treatment.
Changes the REPL's behavior from this:
> var path = 42
> path
A different "path" already exists globally
To this:
> var path = 42
> path
42
Fixes#4512.
Calling send() on an unbound socket forces an implicit bind to
a random port.
332fea5 made the 'listening' event asynchronous. Unfortunately,
it also introduced a bug where the implicit bind was tried more
than once if send() was called again before the first bind operation
completed.
Address that by keeping track of the bind status and making sure that
bind() is called only once.
Fixes#4499.
While it's true that error objects have a history of getting snake_case
properties attached by the host system, it's a point of confusion to
Node users that comes up a lot. It's still 'experimental', so best to
change this sooner rather than later.
This adds a process._fatalException method which is called into from
C++ in order to either emit the 'uncaughtException' method, or emit
'error' on the active domain.
The 'uncaughtException' event is an implementation detail that it would
be nice to deprecate one day, so exposing it as part of the domain
machinery is not ideal.
Fix#4375
Make `fs.createReadStream({ end: 42 })` work.
Before this commit, it worked only when used like this:
`fs.createReadStream({ start: 0, end: 42 })` - only when `start` was specified
by the caller.
Fixes#4423.
socket.readyState, .readable, and .writable behavior changed as
a result of the new streaming interfaces. Updated to be backwards

Consider a production server that uses a REPL to debug. Creating the instance
would wipe out the global cache of modules, and subsequent "require" calls in
the server would be reloaded from disk. The REPL should observe only, without
altering, its environment.
Apply the same optimization to res.end(buf) that is applied to res.end(str).
Speeds up `node benchmark/http_simple_auto -k -c 1 -n 25000 buffer/1`
(non-chunked response body) by about 750x. That's not a typo.
Chunked responses:
$ cat tmp/http-chunked-client.js
// Run `node benchmark/http_simple` in another terminal.
var http = require('http'), url = require('url');
var options = url.parse('http://127.0.0.1:8000/buffer/1/1');
options.agent = new http.Agent({ maxSockets: 1 });
for (var i = 0; i < 25000; ++i) http.get(options);
Before:
$ time out/Release/node tmp/http-chunked-client.js
real 16m40.411s
user 0m9.184s
sys 0m0.604s
After:
$ time out/Release/node tmp/http-chunked-client.js
real 0m5.386s
user 0m2.768s
sys 0m0.728s
That's still a 185x speed-up.
Fixes#4415.
Make parser errors bubble up to the ClientRequest instead of the underlying
net.Socket object.
This is a back-port of commit c78678b from the master branch.
Fixes#3776.
Work around an issue with the glibc malloc() implementation where memory blocks
are never returned to the operating system when they are allocated with brk()
and have overlapping lifecycles.
Fixes#4283.
Because of some of the peculiarities of http, this has a bit of special
magic to handle cases where the IncomingMessage would wait forever in a
paused state.
In the server, if you do not begin consuming the request body by the
time the response emits 'finish', then it will be flushed out.
In the client, if you do not add a 'response' handler onto the request,
then the response stream will be flushed out.
This is a combination of 6 commits.
* XXX net fixup lcase stream
* net: Refactor to use streams2
Use 'socket.resume()' in many tests to trigger old-mode behavior.
* net: Call destroy() if shutdown() is not provided
This is important for TTY wrap streams
* net: Call .end() in socket.destroySoon if necessary
This makes the http 1.0 keepAlive test pass, also.
* net wtf-ish stuff kinda busted
* net fixup
Otherwise (especially with stdin) you sometimes end up in cases
where the high water mark is zero, and the current buffer is at 0,
and it doesn't need a readable event, so it never calls _read().
This fixes the CONNECT/Upgrade HTTP functionality, which was not getting
sliced properly, because readable wasn't emitted on this tick.

Don't allow connections to stall indefinitely if the SSL/TLS handshake does

Enable long stacktraces if NODE_DEBUG=fs is set in the environment. Only
applies to the default rethrow callback; it's to help you find places where
you forgot to pass in a callback.
Use a default callback if the user omitted one. Avoids errors like the one
below:

if (err) return callback(err);
^
TypeError: object is not a function
at fs.appendFile (fs.js:777:21)
at Object.oncomplete (fs.js:297:15)
This commit fixes the behavior of fs.lchmod(), fs.lchown() and fs.readFile()
when the callback is omitted. Before, they silently swallowed errors.
Fixes#4352.
Fix#4331
Using double negate forces values into 32bit space. Because of this
Math.ceil needs to be used. Since NaN comparisons are always false, use
that to our advantage to return 0 if it is.
Also added two tests to verify the changes.
* Added isIP method to make use of inet_pton to cares_wrap.cc
* Modified net.isIP() to make use of new C++ isIP method.
* Added new tests to test-net-isip.js.
This is a back-port of commit fb6377e from the master branch.
While updating the readline test cases to test both "terimal: false" and
"terminal: true" mode, it turned out that the test case testing utf8 chars
being sent over multiple write() calls was failing. The solution is to use
a string_decoder instance when parsing the "keypress" events.
Before this commit, readline was inconsistent in whether or not it would emit
"line" events with or without the trailing "\n" included. When "terminal"
mode was true, then there would be no "\n", when it was false, then the "\n"
would be present. However, the trailing "\n" doesn't add much, and most of the
time people just end up stripping it manually.
Part of #4243.
* Added isIP method to make use of inet_pton to cares_wrap.cc
* Modified net.isIP() to make use of new C++ isIP method.
* Added new tests to test-net-isip.js.
`url.format` should escape ? and # chars in pathname, and # chars in
search, because they change the semantics of the operation otherwise.
Don't escape % chars, or anything else. (see: #4082)
In zlibBuffer(), don't wait for the garbage collector to reclaim the zlib memory
but release it manually. Reduces memory consumption by a factor of 10 or more
with some workloads.
Test case:
function f() {
require('zlib').deflate('xxx', g);
}
function g() {
setTimeout(f, 5);
}
f();
Observe RSS memory usage with and without this commit. After 10,000 iterations,
RSS stabilizes at ~35 MB with this commit. Without, RSS is over 300 MB and keeps
growing.
Cause: whenever the JS object heap hits the high-water mark, the V8 GC sweeps
it clean, then tries to grow it in order to avoid more sweeps in the near
future. Rule of thumb: the bigger the JS heap, the lazier the GC can be.
A side effect of a bigger heap is that objects now live longer. This is harmless
in general but it affects zlib context objects because those are tied to large
buffers that live outside the JS heap, on the order of 16K per context object.
Ergo, don't wait for the GC to reclaim the memory - it may take a long time.
Fixes#4172.
Always add domain, _events, and _maxListeners properties, set to the
default values at first.
Leads to a very very slight perf improvement when using setMaxListeners,
or dealing with a lot of EE objects that don't have any listeners.
This is a flag to make it easier for users to upgrade through the
breaking crypto change, and easier for us to switch it back if it's a
problem.
Explicitly set default encoding to 'buffer' in other tests, in case it
ever changes back.
crypto: Hash and Hmac default to buffers
crypto: Move Cipher encoding logic to JS
crypto: Move Cipheriv encoding logic to JS
crypto: Move Decipher encoding logic to JS
crypto: Move Decipheriv into JS, default to buffers
crypto: Move Sign class to JS
crypto: Better encoding handling in Hash.update
crypto: Move Verify class to JS
crypto: Move DiffieHellman to JS, default to buffers
crypto: Move DiffieHellmanGroup to JS, default to buffers
Also, create a test for this feature
Before there was this weird module-scoped "context" variable which seemingly
shared the "context" of subsequent REPL instances, unless ".clear" was invoked
inside the REPL. To be proper, we need to ensure that each REPL gets its own
"context" object. I literally don't know why this "sharing" behavior was in place
before, but it was just plain wrong.
Consolidates all the formatting options into an "options" object argument.
This is so that we don't have to be constantly remembering the order of
the arguments and so that we can add more formatting options easily.
Closes#4085.
Listen for the 'clientError' event that is emitted when a renegotation attack
is detected and close the connection.
Fixes test/pummel/test-https-ci-reneg-attack.js
Make the 'listening' event handler in the master process see the actual port
that the worker bound to when the worker specified port 0, i.e. a random port.
Encoding failures can be somewhat confusing, especially when they are due to
control flow frameworks auto-filling parameters from the previous step output
values to functions (such as toString and write) that developers don't expect
to take an encoding parameter. By outputting the value as part of the message,
should make it easier to track down these sort of bugs.
This reverts commit 790d651f0d.
This makes Duplex streams unworkable, and would only ever be a special
case for HTTP responses, which is not ideal.
Intead, we're going to just bless the 'finish' event for all Writable
streams in 0.10
