Wildcard server names should not match subdomains.
Quote from RFC2818:
...Names may contain the wildcard
character * which is considered to match any single domain name

not bar.foo.a.com. f*.com matches foo.com but not bar.com.

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.
The null signal test existed, but only tested the case where the target
process existed, not when it did not exist.
Also clarified that SIGUSR1 is reserved by Node.js only for receiveing,
its not at all reserved when sending a signal with kill().
kill(pid, 'O_RDWR'), or any other node constant, "worked". I fixed this
by also checking for 'SIG'. The same as done in the isSignal() function.
Now the signal names supported by process.kill() are the same as those
supported by process.on().
HTTP Parser instance was freed twice, leading to the reusal of it
in several different requests simultaneously.
The flow:
`socketCloseListener` is firing, which calls `socket.read()` to flush
any queued data, `socket.buffer` has data which emits and fires
`socketOnData` in sync, this triggers a parser error which frees the
parser, `socketCloseListener` resumes execution only to have the wrong
parser associated with the socket.
The fix is to only cache the parser after the flushing from the socket,
and to assert in `socketOnData` that `socket === parser.socket`

context._asyncQueue shouldn't be exposed as asyncQueue, as it allows
modification of queues already attached to an event. Which is not
supposed to happend. Instead context._asyncQueue should be copied.
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.
Removing the depth counter while processing the nextTickQueue made it
possible to run out of memory if in an infinite recursive loop using
nextTick(). There was also an edge case where too many callbacks were
pushed onto the nextTickQueue, while not actually being recursive.
This is being done to prevent possible cryptic FATAL ERROR messages from
popping up, and issues being posted about them.
v8's `messages.js` file's `CallSiteGetMethodName` is running through all
object properties and getter to figure out method name of function that
appears in stack trace. This run-through will also read `fd` property of
`UDPWrap` instance's javascript object, making `UNWRAP()` fail.
As a simple alternative to the test case above, one could just keep
reference to the dgram handle and try accessing `handle.fd` after it has
been fully closed.
fix#6536
Before this commit, passing --debugger and other V8 debug switches to
node.js made node print a usage message and exit.
Rewrite the debug argument parser so it only consumes switches that we
understand and pass everything else as-is to V8.
A side effect of this change is that switches like --debugger_agent and
--debugger_port now work. That kind of obsoletes our debugger switches
because they implement pretty much the same functionality but let's
leave them in for now for the sake of convenience and backwards
compatibility.
Fixes#6526.
Emitting an event within a `EventEmitter#once` callback of the same

This commit removes the simple/test-event-emitter-memory-leak test for
being unreliable with the new garbage collector: the memory pressure
exerted by the test case is too low for the garbage collector to kick
in. It can be made to work again by limiting the heap size with the
--max_old_space_size=x flag but that won't be very reliable across
platforms and architectures.
Otherwise the string triggers an assertion error in node_http_parser.c,
line 370:
assert(Buffer::HasInstance(args[0]) == true);
because the first argument is not a Buffer object.
When socket, passed in `tls.connect()` `options` argument is not yet
connected to the server, `_handle` gets assigned to a `net.Socket`,
instead of `TLSSocket`.
When socket is connecting to the remote server (i.e. not yet connected,
but already past dns resolve phase), derive `_connecting` property from
it, because otherwise `afterConnect()` will throw an assertion.
fix#6443
The domain module has been switched over to use the domain module API as
much as currently possible. There are still some hooks in the
EventEmitter, but hopefully we can remove those in the future.
Since RandomBytesRequest makes a call to MakeCallback, needed it to be
a class so AsyncWrap could handle any async listeners.
Also added a simple test for an issue had during implementation where
the memory was being released and returned.
AsyncListener is a JS API that works in tandem with the AsyncWrap class
to allow the user to be alerted to key events in the life cycle of an
asynchronous event. The AsyncWrap class has its own MakeCallback
implementation that core will be migrated to use, and uses state sharing
techniques to allow quicker communication between JS and C++ whether the
async event callbacks need to be called.
When `tls.connect()` is called with `socket` option, it should try to
reuse hostname previously passed to `net.connect()` and only after that
fall back to `'localhost'`.
fix#6409
Currently fs.watch does not have an option to specify if a directory
should be recursively watched for events across all subdirectories.
Several file watcher APIs support this. FSEvents on OS X > 10.5 is
one example. libuv has added support for FSEvents, but fs.watch had
no way to specify that a recursive watch was required.
fs.watch now has an additional boolean option 'recursive'. When set
to true, and when supported, fs.watch will return notifications for
the entire directory tree hierarchy rooted at the specified path.
Previous behaviour was to drop to an openssl prompt
("Enter PEM pass phrase:") when supplying a private key with a
passphrase. This change adds a fourth, optional, paramter that
will be used as the passphrase.
To include this parameter in a backwards compatible way it was
necessary to expose the previously undocumented (and unexposed)
feature of being able to explitly setting the output encoding.
This addresses a current shortcoming of the V8 SetNamedPropertyHandler
function.
It does not provide a way to intercept Object.defineProperty(..) calls.
As a result, these properties are not copied onto the contextified
sandbox when a new global property is added via either a function
declaration or a Object.defineProperty(global, ...) call.
Note that any function declarations or Object.defineProperty() globals
that are created asynchronously (in a setTimeout, callback, etc.) will
happen AFTER the call to copy properties, and thus not be caught.
The way to properly fix this is to add some sort of a
Object::SetNamedDefinePropertyHandler() function that takes a callback,
which receives the property name and property descriptor as arguments.
Luckily, such situations are rare, and asynchronously-added globals
weren't supported by Node's VM module until 0.12 anyway. But, this
should be fixed properly in V8, and this copy function should be removed
once there is a better way.
Fix#6416
The list of supported HTTP methods is available in JS land now so there
is no longer any need to pass a stringified version of the method to the
parser callback, it can look up the method name for itself.
Saves a call to v8::Eternal::Get() in the common case and a costly
v8::String::NewFromOneByte() in the uncommon case.
When the socket closes, the client's http incoming message object was
emitting an 'aborted' event if it had not yet been ended.
However, it's possible, when a response is being repeatedly paused and
resumed (eg, if piped to a slow FS write stream), that there will be a
final chunk remaining in the js-land buffer when the socket is torn
down.
When that happens, the socketCloseListener function detects that we have
not yet reached the end of the response message data, and treats this as
an abrupt abort, immediately (and forcibly) ending the incoming message
data stream, and discarding that final chunk of data.
The result is that, for example, npm will have problems because tarballs
are missing a few bytes off the end, every time.
Closes GH-6402
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
Before this commit, the SIGUSR1 signal handler wasn't installed until
late in the bootstrapping process and we were prone to miss signals
sent by other processes.
This commit installs an early-boot signal handler that merely records
the fact that we received a signal. Once the debugger infrastructure
is in place, the signal is re-raised, kickstarting the debugger.
Among other things, this means that simple/test-debugger-client is
now _much_ less likely to fail.
Commit 30e5366b ("core: Use a uv_signal for debug listener") changed
SIGUSR1 handling from a signal handler to libuv's uv_signal_*()
functionality to fix a race condition (and possible hang) in the
signal handler.
While a good change in itself, it made it impossible to interrupt
long running scripts. When a script is stuck in a busy loop, control
never returns to the event loop, which in turn means the signal
callback - and therefore the debugger - is never invoked.
This commit changes SIGUSR1 handling back to a normal signal handler
but one that treads _very_ carefully.
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.

Don't emit the 'disconnect' event until all workers have gone away.
Before this commit, the event was emitted when all open handles were
closed, which usually - but not always - amounts to the same thing.
Fixes#6346.
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.

The `options` that were being passed in before here are specific to a
single request, which kinda defeats the purpose of using an Agent in the
first place.
On a worse note, these `options` have not yet been "processed" by the
`http.ClientRequest` class, so if `port: null` is set (like it is as the
result of a `url.parse()` call), then they take preference over the
processed values since the agent's "options" get mixed in last in the
`createSocket()` function.
Fixes#6197.
Fixes#6199.
Closes#6231.
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.
Functions created using: `vm.runInNewContext('(function() { })')` will
reference only `proxy_global_` object and not `sandbox_`. Thus in case,
where there're no references to sandbox (such as in example above),
`ContextifyContext` will be destroyed and use-after-free might happen.
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
Slowness being somewhat subjective but determined by running the
test suite a few times and picking off everything that consistently
clocks in at 2 seconds or more.
Honorable mention for simple/test-tls-server-large-request, it often
runs for 10 (!) seconds or more.
Since it is Unix tradition to use exit code 1 for general-purpose script
bail-out, and the way of doing that in Node is to throw an exception and
not catch it, it makes the most sense to exit with 1 when an exception
goes uncaught.
Move the `Invalid Argument` exit to 9, so that it's something specific,
and clear that it's a node internal error.
Also, document the exit codes that we use.
From commit 756ae2c all the WRAP/UNWRAP were moved to a single location
for ease of use. In a single location NO_ABORT should have been used but
wasn't. This caused HandleWrap::Close to abort. Below is the applicable
code change as demonstration there was no abort specified when
unwrapping the object.
void HandleWrap::Close(const FunctionCallbackInfo<Value>& args) {
HandleScope scope(node_isolate);
- HandleWrap *wrap = static_cast<HandleWrap*>(
- args.This()->GetAlignedPointerFromInternalField(0));
+ HandleWrap* wrap;
+ UNWRAP(args.This(), HandleWrap, wrap);
Also included a test that will reproduce the abort.
In cases where the Agent has maxSockets=Infinity, and
keepAlive=false, there's no case where we won't immediately close the
connection after the response is completed.
Since we're going to close it anyway, send a `connection:close` header
rather than a `connection:keep-alive` header. Still send the
`connection:keep-alive` if the agent will actually reuse the socket,
however.
Closes#5838
Adding a new `repl-harmony` test file here because adding the
`--use_strict --harmony` flags on the main repl test file was causing
lots of unrelated failures, due to global variable assignments and
things like that. This new test file is based off of the original
repl.js test file, but has a lot of the tests stripped out. A test case
for this commit is included though.
Fixes#6132.
Replace the growing list of 'isSyntaxError' whackamole conditions with a
smarter approach. This creates a vm Script object *first*, which will
parse the code and raise a SyntaxError right away.
We still do need the test function, but only because strict mode syntax
errors are not recoverable, and should be raised right away. Really, we
should probably *only* continue on "unexpected end of input" SyntaxErrors.
Also fixes a very difficult-to-test nit where the '...' indentation is
not properly cleared when you ^C out of a syntax error.
Closes#6093
This is useful when we need to push some debugging messages out to

This change is not entirely ready for prime time: it's making ~50 tests
fail on Windows, mostly due to timeouts. It's up for debate who is
at fault here: node.js or libuv.
It does however expose a libuv bug on OS X, where the event loop
sometimes gets stuck in uv__io_poll() when there is a single
UV_SHUTDOWN request left in the queue. Needs further investigation.
This reverts commit 4915884da6.
Commit 556b890 added a call to uv_loop_delete() with the intent of
catching handle lifecycle bugs. It worked because it exposed one:
process.on('exit', function() {
console.log('bye'); // Asserts.
});
When run, it asserts with the following message:
Assertion failed: (!uv__has_active_reqs(loop)), function
uv__loop_delete, file ../deps/uv/src/unix/loop.c, line 150.
That's because libuv as of joyent/libuv@3f2d4d5 checks that there are
no in-flight requests when the event loop is destroyed. In the test
case above, the write request for the string hasn't completed yet by
the time node.js exits: the string itself has most likely been written
but libuv hasn't had the opportunity to return the write request to
node.js.
That's why this commit adds a cleanup step right before exit where it
explicitly closes all open handles, then waits until the event loop
exits naturally.
Named pipes (UNIX domain sockets) are shut down first in order to flush
pending write requests. Should go some way towards fixing the Windows
issue where output on stdout/stderr sometimes gets truncated.
Fixesjoyent/libuv#911.
Passing a filename is still supported in place of certain options
arguments, for backward-compatibility, but timeout and display-errors
are not translated since those were undocumented.
Also managed to eliminate an extra stack trace line by not calling
through the `createScript` export.
Added a few message tests to show how `displayErrors` works.
In `Timer.now` always update the loop time by calling uv_update_time.
Previously we were trying to cache the loop time to prevent extra
syscalls. While a noble goal, it can cause timers to fire early in
certain circumstances. Especially seen in cpu bound work loads or work
loads with synchronous file operations.
Previously, calling `vm.createContext(o)` repeatedly on the same `o`
would cause new C++ `ContextifyContext`s to be created and stored on
`o`, while the previous resident went off into leaked-memory limbo.
Now, repeatedly trying to contextify a sandbox will do nothing after
the first time.
To detect this, an independently-useful `vm.isContext(sandbox)` export
was added.
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
This is an important part of the repl use-case.
TODO: The arg parsing in vm.runIn*Context() is rather wonky.
It would be good to move more of that into the Script class,
and/or an options object.
As documented in #3042 and in [1], the existing vm implementation has
many problems. All of these are solved by @brianmcd's [contextify][2]
package. This commit uses contextify as a conceptual base and its code
core to overhaul the vm module and fix its many edge cases and caveats.
Functionally, this fixes#3042. In particular:
- A context is now indistinguishable from the object it is based on
(the "sandbox"). A context is simply a sandbox that has been marked
by the vm module, via `vm.createContext`, with special internal
information that allows scripts to be run inside of it.
- Consequently, items added to the context from anywhere are
immediately visible to all code that can access that context, both
inside and outside the virtual machine.
This commit also smooths over the API very slightly:
- Parameter defaults are now uniformly triggered via `undefined`, per
ES6 semantics and previous discussion at [3].
- Several undocumented and problematic features have been removed, e.g.
the conflation of `vm.Script` with `vm` itself, and the fact that
`Script` instances also had all static `vm` methods. The API is now
exactly as documented (although arguably the existence of the
`vm.Script` export is not yet documented, just the `Script` class
itself).
In terms of implementation, this replaces node_script.cc with
node_contextify.cc, which is derived originally from [4] (see [5]) but
has since undergone extensive modifications and iterations to expose
the most useful C++ API and use the coding conventions and utilities of
Node core.
The bindings exposed by `process.binding('contextify')`
(node_contextify.cc) replace those formerly exposed by
`process.binding('evals')` (node_script.cc). They are:
- ContextifyScript(code, [filename]), with methods:
- runInThisContext()
- runInContext(sandbox, [timeout])
- makeContext(sandbox)
From this, the vm.js file builds the entire documented vm module API.
node.js and module.js were modified to use this new native binding, or
the vm module itself where possible. This introduces an extra line or
two into the stack traces of module compilation (and thus into most
stack traces), explaining the changed tests.
The tests were also updated slightly, with all vm-related simple tests
consolidated as test/simple/test-vm-* (some of them were formerly
test/simple/test-script-*). At the same time they switched from
`common.debug` to `console.error` and were updated to use
`assert.throws` instead of rolling their own error-testing methods.
New tests were also added, of course, demonstrating the new
capabilities and fixes.

`dns.lookup` defaults to selecting IPv4 record even if IPv6 is available
for the desired zone. Generally, this approach works, but if IPv4
address is unavailable - there'll be no other way to opt-out and connect using
IPv6 address than calling `dns.lookup` and passing it to `.connect()`
directly.
This commit adds `family` option to `net.connect` method to figure out
this issue.
It only fails once in about 1000 times, but that's too many.
It's timing dependent, and the main behavior is covered by the other
assertions in the test anyway.
This allows automatically-inserted headers to be removed permanently by
calling OutgoingMessage.removeHeader() on them, as if they were normal
headers.
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.

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.)

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)`.

In other Writable streams, the 'finish' event means that all of the data
was written, and flushed to the underlying system.
The 'prefinish' event means that end() was called, and all of the data
was processed, but not necessarily completely flushed.
This change brings the http OutgoingMessage classes more in sync with
the other Writable classes throughout Node.
Unfortunately, this change highlights an issue with http
IncomingMessages, where the _dump() method will not actually pull the
data off the wire. This is a minor issue that is typically only
relevant in test cases, and will be addressed in the next commit.
This removes a dubious performance "optimization" where strings body
chunks were concatenated to one another (and to the headers) without any
regard for their encoding.

v0.10 allows strings for the offset, length and port arguments to
dgram.send() and dgram.sendto() but master before this commit would

Go beyond what v0.10 does and also add range checks: offset and length
should be >= 0, port should be between 1 and 65535.
That particular change needs to be back-ported to v0.10 because passing

Interestingly enough, a negative port number is accepted in v0.10 but
is silently ignored.
This commit exposed a bug in the simple/test-dgram-close test which
has also been fixed.
smalloc.alloc now accepts an optional third argument which allows
specifying the type of array that should be allocated. All available
types are now located on smalloc.Types.
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
It shouldn't ignore it!
There're two possibile cases, which should be handled properly:
1. Having a default `SNICallback` which is using contexts, added with
`server.addContext(...)` routine
2. Having a custom `SNICallback`.
In first case we may want to opt-out setting `.onsniselect` method (and
thus save some CPU time), if there're no contexts added. But, if custom
`SNICallback` is used, `.onsniselect` should always be set, because
server contexts don't affect it.
* Numeric values passed to alloc were converted to int32, not uint32
before the range check, which allows wrap around on ToUint32. This
would cause massive malloc calls and v8 fatal errors.
* dispose would not check if value was an Object, causing segfault if a
Primitive was passed.
* kMaxLength was not enumerable.
Run the garbage collector before running the actual test. It doesn't
matter now but if in the future something in node.js core creates a lot
of reclaimable garbage, that will break the test's expectation.
* Run the garbage collector before creating the big array. It doesn't
matter now but if in the future something in node.js core creates
a lot of reclaimable garbage, that will break the test's expectation.
* The first RSS check was being done too late. The garbage collector
might have run before the check, throwing off the 'reclaimed memory'
calculation.
* Due to changes in how V8 represents the big array internally, the
actual memory usage is just below 256 MB on x64. Update the test's
expectation.
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.
Use the StringBytes::IsValidString() function introduced in commit
dce26cc to ensure that the input string meets the expectations of the
other StringBytes functions before processing it further.
Fixes the following assertion:
Assertion failed: (str->Length() % 2 == 0 && "invalid hex string
length"), function StorageSize, file ../../src/string_bytes.cc,
line 301.
Fixes#5725.
Don't throw an exception when the argument to %j is an object that
contains circular references, it's not helpful. Catch the exception
and return the string '[Circular]'.
Passing the number of sent bytes to the callback is superfluous;
datagram sockets operate in atomic mode: either the sendmsg() system
call succeeds or it fails but it never does partial writes.
Instead, report send errors to the callback. UDP error reporting is
fairly haphazard on most platforms. You should not expect reliable
delivery of anything besides EMSGSIZE and (possibly) ENETDOWN and
ENETUNREACH.
Fixes#2608.
This prevents the following sort of thing from being confusing:
```javascript
stream.on('data', function() { console.error('got data'); });
stream.pause(); // stop reading
// turns out no data is available
stream.push(null);
// Hand the stream to someone else, who does stuff...
setTimeout(function() {
// too late! 'end' is already emitted!
stream.on('end', function() { console.error('got end'); });
});
```
With this change, the `end` event is not emitted until you call `read()`
*past* the EOF null. So, a paused stream will not swallow the `end`
event and emit it before you `resume()` the stream.
The title shouldn't be too long; libuv's uv_set_process_title() out of
security considerations no longer overwrites envp, only argv, so the
maximum title length is possibly quite short.
Fixes#5908.
SlowBuffer(0) passes NULL instead of doing malloc(0). So when someone
attempted to SlowBuffer(0).slice(0, 1) an assert would fail in
smalloc::SliceOnto.
It's important that the check go where it is because the resulting
Buffer needs to have external array data allocated. In the case a user
tries to slice a zero length Buffer it will also have NULL passed as the
data argument.
Also fixed where the .parent attribute was set for zero length Buffers.
There is no need to track the source of slice if the slice isn't
actually occurring.
Closes#5860
In streams2, there is an "old mode" for compatibility. Once switched
into this mode, there is no going back.
With this change, there is a "flowing mode" and a "paused mode". If you
add a data listener, then this will start the flow of data. However,
hitting the `pause()` method will switch *back* into a non-flowing mode,
where the `read()` method will pull data out.
Every time `read()` returns a data chunk, it also emits a `data` event.
In this way, a passive data listener can be added, and the stream passed
off to some other reader, for use with progress bars and the like.
There is no API change beyond this added flexibility.
It will be confusing if later on we add Buffer#dispose(), and smalloc is
its own cpp api anyways. So instead create a new require('smalloc') to
expose the previous Buffer.alloc/dispose methods, and expose copyOnto
and kMaxLength as well.
Other changes:
* Added documentation and additional tests.
* smalloc::CopyOnto has changed from using assert() to throwing errors
on bad argument values because it is not exposed to the user.
* Minor style fixes.
When using url.parse(), path and pathname usually return '/' when there
is no path available. However when you have a protocol that contains
non-lowercase letters and the input string does not have a trailing
slash, both path and pathname will be undefined.
