Make vm.runInContext() and vm.runInNewContext() stop copying the Proxy
object from the parent context into the new context when --harmony or
--harmony_proxies is in effect because it overwrites the new context's
native Proxy object.
This commit also adds a regression test for Harmony symbols. They work
okay in the current implementation and the test should ensure it stays
that way.

Add a new 'tracing' module with a v8 property that lets the user
register listeners for gc events. The listeners are invoked after
every garbage collection cycle with 'before' and 'after' statistics.
Useful for monitoring tools that want to keep track of memory usage.
Create a new HandleScope before looking up the object context with
v8::Object::CreationContext(), else we leak the Local<Context> into
the current HandleScope.
That's relatively harmless unless the HandleScope is long-lived and
MakeCallback() is called a lot. In a scenario like that, we may end
up leaking a lot of memory.
What is unfortunate about this change is that we're trying hard to
eradicate the node_isolate global. Longer term, we will probably have
to change the MakeCallback() prototype to one that requires an explicit
v8::Isolate* argument.
Make it possible to invoke MakeCallback() on a v8::Value but only for
the variant that takes a v8::Function as the thing to call.
The const char* and v8::String variants still require a v8::Object
because the function to call is looked up as a property on the receiver,
but that only works when the receiver is an object, not a primitive.

The ability to add/remove an AsyncListener to an object after its

Before this commit, verification exceptions had err.message set to the
OpenSSL error code (e.g. 'UNABLE_TO_VERIFY_LEAF_SIGNATURE').
This commit moves the error code to err.code and replaces err.message
with a human-readable error. Example:
// before
{
message: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE'
}
// after
{
code: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE',
message: 'unable to verify the first certificate'
}
UNABLE_TO_VERIFY_LEAF_SIGNATURE is a good example of why you want this:
the error code suggests that it's the last certificate that fails to
validate while it's actually the first certificate in the chain.
Going by the number of mailing list posts and StackOverflow questions,
it's a source of confusion to many people.
Before when an AsyncListener object was created and the "create"
callback returned a value, it was necessary to construct a new Object
with the same callbacks but add a place for the new storage value.
Now, instead, a separate storage array is kept on the context which is
used for any return value of the "create" callback. This significantly
reduces the number of Objects that need to be created.
Also added a flags property to the context to quickly check if a
specific callback was available either on the context or on the
AsyncListener instance itself.
Few other minor changes for readability that were difficult to separate
into their own commit.
This has not been optimized yet.
This is a slightly modified revert of bc39bdd.
Getting domains to use AsyncListeners became too much of a challenge
with many edge cases. While this is still a goal, it will have to be
deferred for now until more test coverage can be provided.
Instead of checking the uid on the array index of the queue, instead the
object property "uid" was checked on the queue iteself. Because this
will always evaluate to "undefined" the same listener could be added
multiple times to the same context.
There was a flaw in the old API that has been fixed. Now the
asyncListener callback is now the "create" object property in the
callback object, and is optional.
Eliminate a race condition between uv_async_send and the closing of the

This is a comment change, where it originally says disabling TLS
Compression protects against BEAST attack. But in fact, it is the
CRIME attack(Compression Ratio Info-leak Made Easy) that makes use
of TLS Compression and not BEAST.
BEAST(Browser Exploit Against SSL/TLS) is an entirely another variant
making use of the chosen boundary attack against CBC mode in
encryption.
Just making sure, that the exact reason for disabling TLS compression
must be made clear and not be misleading with some other attack.

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().
Replace call to Number::New() with a call to Integer::NewFromUnsigned().

has dropped from the 'most costly functions' top ten altogether.

context._asyncQueue shouldn't be exposed as asyncQueue, as it allows
modification of queues already attached to an event. Which is not

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

Fixes a 4 byte leak on handles closing. AKA The Walmart leak.
MakeCallback doesn't have a HandleScope. That means the callers scope
will retain ownership of created handles from MakeCallback and related.
There is by default a wrapping HandleScope before uv_run, if the caller
doesn't have a HandleScope on the stack the global will take ownership
which won't be reaped until the uv loop exits.
If a uv callback is fired, and there is no enclosing HandleScope in the
cb, you will appear to leak 4-bytes for every invocation. Take heed.

The domain module has been switched over to use the domain module API as

pbkdf2_req has been renamed to PBKDF2Request and converted to a class.
It now uses AsyncWrap::MakeCallback.
Also includes, using env()->ondone_string() instead of "ondone" and
using malloc instead of new char[].
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.
Profiling suggested that on Linux sometimes over 10% of CPU time was
being spent inside the systemtap probe entry points in the binding
layer, even when the process was not actively being traced with the
`stap` tool.
That's why this commit makes it possible to use the *_ENABLED() macros
and bail out early when we're not being traced, reducing the overhead
of unused probes to (almost) zero.
Said macros were already being generated by `dtrace -h` but were not
usable because they rely on external definitions. To remedy that, we
now generate the accompanying object files with `dtrace -G`.
This commit includes a change to libuv that has been landed upstream in
commit joyent/libuv@3c172ea.
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.
There was no need to share state between C++ and JS for these two
values. So they have been moved to their respective locations. This will
help performance only a tiny bit, but it does help code complexity much
more.
We need to keep ObjectWrap around for module authors (we think), but
v8 3.21 broke node_object_wrap.h with respect to MSVC. Coincidentally,
we no longer use ObjectWrap at all in core, and native modules might
as well use their own entirely internal implementation if they need it.
Turns out that we don't use node_object_wrap.h any more in core,
and, with v8 3.21, it's breaking our Windows build. Removing refs
to it everywhere (and adding node.h in one case where it was the
only way node.h was being included), we have restored the Windows
build.
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

v8::String::NewFromOneByte() in the uncommon case.
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.
Because it's possible for the data within a Buffer instance to be

The previous commit changes the profiler idle notifier so that it only
gets started when a --prof or --prof_lazy argument is specified on the
command line.
This commit adds two internal methods to the process object that allows
one to start and stop the idle notifier programmatically.
The previous commit adds a notifier that tells the V8 profiler when
node.js is idle, i.e. when it's about to start sleeping in the
platform's equivalent of epoll_wait().
This commit adds a heuristic that only starts the notifier when the
V8 profiler is started from the command line.
Inform V8's CPU profiler when we're idle. The profiler is
sampling-based but not all samples are created equal; mark the wall
clock time spent in epoll_wait() and friends so profiling tools can
filter it out. The samples still end up in v8.log but with state=IDLE
rather than state=EXTERNAL.
Drop the ObjectWrap dependency in favor of an internal WeakObject class.
Let's us stop worrying about API and ABI compatibility when making
changes to the way node.js deals with weakly persistent handles
internally.
The default entropy source is /dev/urandom on UNIX platforms, which is
okay but we can do better by seeding it from OpenSSL's entropy pool.
On Windows we can certainly do better; on that platform, V8 seeds the
random number generator using only the current system time.
Fixes#6250.
The test case from the previous commit exposed a regression in the way
that c-ares errors are reported to JS land. Said regression was
introduced in commit 756b622 ("src: add multi-context support").
Fixes the following test failure:
$ out/Release/node test/simple/test-dns-regress-6244
util.js:675
var errname = uv.errname(err);

at Object.exports._errnoException (util.js:675:20)
at errnoException (dns.js:43:15)
at Object.onresolve [as oncomplete] (dns.js:145:19)
lib/dns.js erroneously assumed that the error code was a libuv error
code when it's really a c-ares status code. Libuv handles getaddrinfo()
style lookups (which is by far the most common type of lookup), that's
why this bug wasn't discovered earlier.
Don't forget to initialize the c-ares task tree head when creating a
new Environment. Oversight from the multi-context work that landed
in commit 756b622.

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.
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.
Fix pointer unwrapping when T is a class with more than one base class.
Before this commit, the wrapped void* pointer was cast directly to T*
without going through ObjectWrap* first, possibly leading to a class
instance pointer that points to the wrong vtable.
This change required some cleanup in various files; some classes
used private rather than public inheritance, others didn't derive
from ObjectWrap at all...
Fixes#6188.
This commit makes it possible to use multiple V8 execution contexts
within a single event loop. Put another way, handle and request wrap
objects now "remember" the context they belong to and switch back to
that context when the time comes to call into JS land.
This could have been done in a quick and hacky way by calling
v8::Object::GetCreationContext() on the wrap object right before
making a callback but that leaves a fairly wide margin for bugs.
Instead, we make the context explicit through a new Environment class
that encapsulates everything (or almost everything) that belongs to
the context. Variables that used to be a static or a global are now
members of the aforementioned class. An additional benefit is that
this approach should make it relatively straightforward to add full
isolate support in due course.
There is no JavaScript API yet but that will be added in the near
future.
This work was graciously sponsored by GitHub, Inc.
From commit 756ae2c all the WRAP/UNWRAP were moved to a single location

unwrapping the object.

The new libuv API allows for more cleanup and deduplication but I'm
saving that for another day.
If the string is external then the length can be quickly retrieved. This
is especially faster for large strings that are being treated as UTF8.
Also, if the string is external then there's no need for a full
String::WriteUtf8 operation. A simple memcpy will do.
This is useful when we need to push some debugging messages out to
stderr, without going through the Writable class, or triggering any kind
of nextTick or callback behavior.
* Exit with an error message when the option is not a node or V8 option.
* Remove the option_end_index global. Needs to happen anyway for
the multi-context work, might as well land it in master now.
* Add a smidgen of const-correctness.
* Pay off a few years of accrued technical debt.
Don't call uv_loop_delete() until we've figured out a way to gracefully
close open handles. See also commit 4915884 and its subsequent revert
in commit 980cbd5.
This reverts commit 556b890ad9.
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.
Remove NodeBIO::GetMethod() and replace calls to BIO_new() with calls
to the new NodeBIO::New() function.
This commit basically reshuffles some code in order to make it explicit
that the NodeBIO BIO_METHOD is const.
Before this commit it was declared static (in a header file!), meaning
it got duplicated in every file that includes it.
A few duplicated pointers is not the end of the world but it introduces
a lot of potential for confusion because root_cert_store in file A is
not the root_cert_store in file B.
Moral of the story: don't declare static variables in header files.
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.
This was a remnant of the original Contextify code, wherein
ContextifyContext was a user-exposed object. In vm, it is not, so all
of the ObjectWrap and function-template stuff for the ContextifyContext
constructor is now unnecessary.
Due to a lot of the util.is* checks there was much unnecessary overhead
for the most common use case of Buffer. Which is creating a new Buffer
instance for data from incoming I/O. NativeBuffer is a simple way to
bypass all the unneeded checks and simply hand back a Buffer instance
while setting the length.
On windows process exit codes can be greater than INT32_MAX. This used
to be not much of a problem - greater values would just come out
negative. However since ca9eb71 a negative result value indicates that
uv_spawn() has failed, so this is no longer acceptable.
Instead of doing all the domain handling in core, allow the domain to
set an error handler that'll take care of it all. This way the domain
error handling can be abstracted enough for any user to use it.
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.

The C++ API has been changed so the passed length is the byte size of
the data, not the length of the array.
This was done so users need to explicitly define how much memory they
want allocated.
Commit 03e008d introduced src/tls_wrap.cc and src/tls_wrap.h but
said files copied on the order of 1 kLoC from src/node_crypto.cc
and src/node_crypto.h. This commit undoes some of the duplication.
Fixes#6024.
RandomBytes() allocated memory with new[] which was then handed off to
Buffer::Use() which eventually releases it again with free().
Mixing the two is technically a violation of the spec and besides, it's
generally frowned upon.
Achieve a minor speed-up by looking up the timeout callback on the timer
object by using an array index rather than a named property.
Gives a performance boost of about 1% on the misc/timers benchmarks.
Code cleanup: don't call a Connection object `p` in some places, `c` in
other places and `ss` in yet other places. Let's just call it `conn`.
This also fixes about a million style errors in one fell swoop.
Don't create an Integer when setting a numeric index on an object or an
array, use the version of v8::Object::Set() that takes an uint32_t.
Change the types of the variables from int to uint32_t and clean up
some code consistency issues while we're here.
Don't set the oncomplete property in src/cares_wrap.cc, we can do it
just as easily in lib/dns.js.
Switch two closures to the 'function with _this_ object' model. Makes
it impossible for an overzealous closure to capture too much context
and accidentally hold on to too much memory.
Use v8::Integer::NewFromUnsigned() when updating the writeQueueSize
field.
Before this commit, it used v8::Integer::New() but that takes an
int32_t. It's unlikely for a write queue to grow beyond 2**31-1 bytes
but let's use the unsigned integer constructor anyway, just in case.
Change process.domain to use a getter/setter and access that property
via an array index. These are much faster to get from c++, and it can be
passed to _setupDomainUse and stored as a Persistent<Array>.
InDomain() and GetDomain() as trivial ways to access the domain
information in the native layer. Important because we'll be able to
quickly access if a domain is active. Instead of just whether the domain
module has been loaded.
Don't use v8::Object::SetHiddenValue() to keep a reference alive to the
buffer, we can just as easily do that from JS land and it's a lot faster
to boot.
Because the buffer is now a visible property of the write request
object, it's essential that we do *not* log it - we'd be effectively
serializing the whole buffer to a pretty-printed string.
* Change calls to String::New() and String::NewSymbol() to their
respective one-byte, two-byte and UTF-8 counterparts.
* Add a FIXED_ONE_BYTE_STRING macro that takes a string literal and
turns it into a v8::Local<v8::String>.
* Add helper functions that make v8::String::NewFromOneByte() easier to
work with. Said function expects a `const uint8_t*` but almost every
call site deals with `const char*` or `const unsigned char*`. Helps
us avoid doing reinterpret_casts all over the place.
* Code that handles file system paths keeps using UTF-8 for backwards
compatibility reasons. At least now the use of UTF-8 is explicit.
* Remove v8::String::NewSymbol() entirely. Almost all call sites were
effectively minor de-optimizations. If you create a string only once,
there is no point in making it a symbol. If you are create the same
string repeatedly, it should probably be cached in a persistent
handle.
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.
* Moved the ToObject check out of smalloc::Alloc and into JS. Direct
usage of that method is for internal use only and so can bypass the
possible coercion.
* Same has been done with smalloc::SliceOnto.
* smalloc::CopyOnto will now throw if passed argument is not an object.
* Remove extra TargetFreeCallback function. There was a use for it when
it was working with a Local<T>, but that code has been removed making
the function superfluous.
Add is_named_pipe(), is_named_pipe_ipc() and is_tcp() and update the
code base to use those rather than `stream->type == UV_FOO` and
`reinterpret_cast<uv_pipe_t*>(handle)->ipc` style checks.
Hide member fields behind getters. Make the fields themselves const
in the sense that the pointer is non-assignable - the pointed to object
remains mutable.
Makes reasoning about lifecycle and mutability a little easier.
