Replace call to Number::New() with a call to Integer::NewFromUnsigned().
Profiling a Real World(TM) application with perf(1) suggests that the
conversion of its argument from integer to double is disproportionally
costly: over 60% of CPU cycles accountable to WriteStringImpl() are
attributable to the conversion.
After changing it to Integer::NewFromUnsigned(), WriteStringImpl()
has dropped from the 'most costly functions' top ten altogether.
Add a 'serialNumber' property to the object that is returned by
tls.CryptoStream#getPeerCertificate(). Contains the certificate's
serial number encoded as a hex string. The format is identical to
`openssl x509 -serial -in path/to/certificate`.
Fixes#6583.
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.
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.
BaseObject is a class that just handles the Persistent handle attached
to the class instance.
This also removed WeakObject. Reordering the inheritance chain helps
prevent unneeded calls on instances that don't call MakeCallback.
Make it more difficult to accidentally leak handles by removing the
top-level HandleScope. Now if there's no valid HandleScope now, V8
will complain and, in debug builds, abort.

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.

Create a HandleScope before calling the Environment::GetCurrent() that
takes a v8::Isolate* as an argument because it creates a handle with
the call to v8::Isolate::CurrentContext().
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.
Update the list of root certificates in src/node_root_certs.h with

Fixes#6013.
CONTAINER_OF was introduced a while ago but was not used consistently
everywhere yet. This commit fixes that.
Why CONTAINER_OF instead of container_of? The former makes it crystal
clear that it's a macro, not a function.
Unbreak the build when linking against a shared version of OpenSSL that
doesn't support NPN (Next Protocol Negotiation.)
Fixes the following build error:

Otherwise it might get stall (`Peek()` will return zero-length chunk)

|i| and |j| arent't used when building without crypto support. Hat tip
to Brian White.
Rename |l| to |k| while we're here because it's quite hard to discern
from |i| or |j| with some fonts.
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.
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
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.
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
altered after instantiation, or in case a user attempts to do something
like the following:
Buffer.prototype.fill.call({}, 10, 0, 10);
It doesn't result in a segfault.
This change makes several improvements to the ustack helper and MDB
support:
- ustack helper and MDB: add support for two-byte strings
(necessary to print many filenames in stacktraces in 0.10 and later).
- ustack helper: fix position numbers, which were off by a factor of two
- ustack helper: fix frames with undefined Scripts (e.g., "RegExp")
- ustack helper: add stub frames
- MDB: add support for sliced strings
- MDB: sync up with changes from the illumos version of the module
Fixes#6309Closes#6318
Mea culpa, I didn't properly resolve a merge conflict in the last two
commits. The resulting segmentation fault only happened on Linux and
only sometimes.
Fixes#6306.
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);
^
Error: err >= 0
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.
Fixes#6244.
Apparently, context->Global() won't be destroyed if the context itself
isn't marked as weak and independent.
Also, the weakness flag should be cleared once the weak callback is
executed, otherwise we'll get crashes in Debug builds.
fix#6115 and #6201
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
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.
Stop gcc from getting confused, explicitly cast the return value from

This commit changes src/tcp_wrap.cc and src/udp_wrap.cc just enough to
get by (i.e. to compile and function correctly.)
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.

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.
Don't create a superfluous Number object, just use the version of
v8::Object::Get() that takes an unsigned int. Convert the index to
unsigned int while we're here.
The type of the expression `(uint16_t) server_names_len + 2` gets
implicitly widened to int. Change the type of server_names_len to
uint32_t to avoid the following warnings:
../../src/node_crypto_clienthello.cc:144: warning: comparison
between signed and unsigned integer expressions
../../src/node_crypto_clienthello.cc:146: warning: comparison
between signed and unsigned integer expressions
Update a few more `Local<T>::New(isolate, persistent)` call sites to
`PersistentToLocal(isolate, persistent)` - the latter has a fast path
for non-weak persistent references.
When doing `FreeEmpty`, `NodeBIO` skips pre-allocated `head_` buffer.
However this might lead to double-freeing buffers since in `~NodeBIO()`
we're starting deallocation from `head_` buffer.
Commit 78d9094 updated src/*.cc to use the version of PersistentToLocal
that takes a v8::Isolate* as its first argument. This commit removes
the non-isolate version.
Build breakage accidentally introduced in 8e29ce9 during code cleanup.
HAVE_OPENSSL is always defined (as either 0 or 1) so use #if rather
than #ifdef.
Fixes#5979.
To prevent all unnecessary calls to JS from MakeCallback, the remaining
two immediate return variables inTick and lastThrew have been added to
infoBox. Now MakeCallback should never need to call into JS unless it
absolutely has to.
Also removed Tock. Performance tests showed it was at least as fast or
faster than using a normal object, and this is more readable.
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.
Performs a quick, non-exhaustive check on the input string to see if
it's compatible with the specified string encoding.
Curently it only checks that hex strings have a length that is a
multiple of two.
Prior, strings would first be converted to a Buffer before being written
to disk. Now the intermediary step has been removed.
Other changes of note:
* Class member "must_free" was added to req_wrap so to track if the
memory needs to be manually cleaned up after use.
* External String Resource support, so the memory will be used directly
instead of copying out the data.
* Docs have been updated to reflect that if position is not a number
then it will assume null. Previously it specified the argument must be
null, but that was not how the code worked. An attempt was made to
only support == null, but there were too many tests that assumed !=
number would be enough.
* Docs update show some of the write/writeSync arguments are optional.
* Use ARRAY_SIZE() rather than scanning until we hit a NULL entry.
* Fix `-fsigned-char -Wnarrowing` compiler warnings. Harmless but
numerous and annoying.
* Static-ify the modp_group and mod_groups arrays.
* Const-ify the modp_groups array.
It imports the definition into every source file that includes
string_bytes.h, as evidenced by the build suddenly breaking left
and right because of missing Handle/Local/String/Value imports.
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.
V8 3.20.9 enforces that external pointers are aligned on a two-byte
boundary.
We cannot portably guarantee that for the source code strings that
tools/js2c.py generates so simply stop using String::NewExternal()
altogether (and by extension String::ExternalAsciiStringResource).
Fixes the following run-time assert:
FATAL ERROR: v8::String::NewExternal() Pointer is not aligned
And process.getgid() too.
Commit ed80638 changed fs.chown() and fs.fchown() to only accept
unsigned integers. Make process.getuid() and process.getgid() follow
suit.
This commit should unbreak npm on OS X - it's hitting the new 'uid must
be an unsigned int' check when installing as e.g. user 'nobody' (which
has an UID of -2 in /etc/passwd or 4294967294 when cast to an uid_t.)
Fixes#5904.

This incarnation of macros.py is only used to disable the (d)trace
macros. Rename it so it better reflects its purpose. A new macros.py
will be added in a follow-up commit.
Before this commit, fs.chown() and fs.fchown() coerced the uid and gid
arguments to signed integers which is wrong because uid_t and gid_t are
unsigned on most all platforms and IDs that don't fit in a signed
integer do exist.
This commit changes the aforementioned functions to take unsigned ints
instead. No test because we can't assume the system has [GU]IDs that
large.
This change depends on joyent/libuv@d779eb5.
Fixes#5890.
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.
Just forward declare struct sockaddr, the struct is never actually
dereferenced in src/node_internals.h.
Before this commit, it included sys/socket.h but that header doesn't
exist on Windows.
Libuv now returns errors directly. Make everything in src/ and lib/
follow suit.
The changes to lib/ are not strictly necessary but they remove the need
for the abominations that are process._errno and node::SetErrno().
Prep work for removing process._errno. The handle.getsockname() function
will return a status code in the future and set the address and port
properties on the object that's passed in from JS land.
Commit 636ca7c adds an optimization that casts strong Persistent<T>
handles directly to Local<T> handles to avoid the overhead of creating
new HandleScope-rooted Local<T> handles all the time.
One gotcha that I missed is that it's no longer legal to reference the
Local<T> after calling Persistent<T>::Dispose(). This commit addresses
that.
Helps catch bugs early on. Without it, V8 throws the fairly
unhelpful exception "TypeError: undefined is not a function" -
unhelpful because there is no stack trace.
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.
In fa10b75 the assert to check if data == NULL was remove for
smalloc::Alloc with no callback. It should have also been removed where
a callback is accepted.
No sense in making sure that length == 0 if data == NULL because devs
already have to be responsible for checking that length is the same as
the char* they're passing in.
It hits a compiler bug in gcc <= 4.4 similar to the issue that was
recently addressed in commit 157d2bc:

Remove the helper function, it was only used in a couple of places.
Should fix the build on Ubuntu 10.04.
Fixes#5844.
Previously there was no way to pass a Function callback directly to
MakeCallback and support domains. The check has been added so that users
never have to worry about supporting domains while using MakeCallback.
X509_STORE_add_cert increment reference of passed `x509` cert,
`X509_free` must be called to avoid memory leak.

Fix bug where if dev passed a callback to Alloc then called AllocDispose
it wouldn't bother to pass the data to the callback and instead would
just free it.
This is a big commit that touches just about every file in the src/
directory. The V8 API has changed in significant ways. The most
important changes are:
* Binding functions take a const v8::FunctionCallbackInfo<T>& argument
rather than a const v8::Arguments& argument.
* Binding functions return void rather than v8::Handle<v8::Value>. The
return value is returned with the args.GetReturnValue().Set() family
of functions.
* v8::Persistent<T> no longer derives from v8::Handle<T> and no longer
allows you to directly dereference the object that the persistent
handle points to. This means that the common pattern of caching
oft-used JS values in a persistent handle no longer quite works,
you first need to reconstruct a v8::Local<T> from the persistent
handle with the Local<T>::New(isolate, persistent) factory method.
A handful of (internal) convenience classes and functions have been
added to make dealing with the new API a little easier.
The most visible one is node::Cached<T>, which wraps a v8::Persistent<T>
with some template sugar. It can hold arbitrary types but so far it's
exclusively used for v8::Strings (which was by far the most commonly
cached handle type.)
UsingDomains() assigned process_tickCallback when it had already
been set by MakeCallback() a few frames down the call stack.
Dispose the handle first or we'll retain whatever is in the lexical
closure of the old process._tickCallback function.
Fixes#5795.
Now that Buffer instantiation has improved, the SlabAllocator is an
unnecessary layer of complexity preventing further performance
optimizations.
Currently there is a small performance loss with very small stream
requests, but this will soon be addressed.
Most TryCatch blocks have SetVerbose flag on, this tells V8 to report
uncaught exceptions to debugger.
FatalException handler is called from V8 Message listener instead from
the place where TryCatch was used. Otherwise uncaught exceptions are
logged twice.
See comment in `deps/v8/include/v8.h` for explanation of SetVerbose
flag:
> By default, exceptions that are caught by an external exception
> handler are not reported. Call SetVerbose with true on an
> external exception handler to have exceptions caught by the
> handler reported as if they were not caught.
The flag is used by `Isolate::ShouldReportException()`, which is called
by `Isolate::DoThrow()` to decide whether an exception is considered
uncaught.
Might cause write head running over read head, when there were no
allocation and `Commit()` was called. Source of at least one test
failure on windows (`simple/test-https-drain.js`).
gcc 4.2 on OS X gets confused about the call to node::Buffer::Data().
Fully qualify the function name to help it along.
Fixes the following build error:
../../deps/v8/include/v8.h: In function ‘char*
node::Buffer::Data(v8::Handle<v8::Value>)’:
../../deps/v8/include/v8.h:900: error: ‘class v8::Data’
is not a function,
../../src/node_buffer.h:38: error:
conflict with ‘char* node::Buffer::Data(v8::Handle<v8::Object>)’
../../src/node_buffer.cc:94: error:
in call to ‘Data’
Buffer(<String>) used to pass the string to js where it would then be
passed back to cpp for processing. Now only the buffer object
instantiation is done in js and the string is processed in cpp.
Also added a Buffer api that also accepts the encoding.
Old fill would take the char code of the first character and wrap around
the int to fit in the 127 range. Now fill will duplicate whatever string
is given through the entirety of the buffer.
Note: There is one bug around ending on a partial fill of any character
outside the ASCII range.
Memory allocations are now done through smalloc. The Buffer cc class has
been removed completely, but for backwards compatibility have left the
namespace as Buffer.
The .parent attribute is only set if the Buffer is a slice of an
allocation. Which is then set to the alloc object (not a Buffer).
The .offset attribute is now a ReadOnly set to 0, for backwards
compatibility. I'd like to remove it in the future (pre v1.0).
A few alterations have been made to how arguments are either coerced or
thrown. All primitives will now be coerced to their respective values,
and (most) all out of range index requests will throw.
The indexes that are coerced were left for backwards compatibility. For
example: Buffer slice operates more like Array slice, and coerces
instead of throwing out of range indexes. This may change in the future.
The reason for wanting to throw for out of range indexes is because
giving js access to raw memory has high potential risk. To mitigate that
it's easier to make sure the developer is always quickly alerted to the
fact that their code is attempting to access beyond memory bounds.
Because SlowBuffer will be deprecated, and simply returns a new Buffer
instance, all tests on SlowBuffer have been removed.
Heapdumps will now show usage under "smalloc" instead of "Buffer".
ParseArrayIndex was added to node_internals to support proper uint
argument checking/coercion for external array data indexes.
SlabAllocator had to be updated since handle_ no longer exists.
If the user knows the allocation is no longer needed then the memory can
be manually released.
Currently this will not ClearWeak the Persistent, so the callback will
still run.
If the user passed a ClearWeak callback, and then disposed the object,
the buffer callback argument will == NULL.
smalloc is a simple utility for quickly allocating external memory onto
js objects. This will be used to centralize how memory is managed in
node, and will become the backer for Buffers. So in the future crypto's
SlabBuffer, stream's SlabAllocator will be removed.
Note on the js API: because no arguments are optional the order of
arguments have been placed to match their cc counterparts as closely as
possible.
Libuv may provide a NULL buffer to the uv_read callback in case of an
error, so with this assert we'd be using the api incorrectly. None of
the current DoRead implementations rely on this constraint, either.
Resolves minor discrepancies between android and standard POSIX systems.
In addition, some configure parameters were added, and a helper-script
for android configuration. Ideally, this script should be merged into
the standard configure script.
To build for android, source the android-configure script with an NDK
path:
source ./android-configure ~/android-ndk-r8d
This will create an android standalone toolchain and export the
necessary environment parameters.
After that, build as normal:
make -j8
After the build, you should now have android-compatible NodeJS binaries.
Suppress the following warning:
../../src/cares_wrap.cc: In function ‘v8::Handle<v8::Value>

When large strings are used they cause v8's GC to spend a lot more time
cleaning up. In these cases it's much faster to use external string
resources.
UTF8 strings do not use external string resources because only one and
two byte external strings are supported.
EXTERN_APEX is the value at which v8's GC overtakes performance.
The following table has the type and buffer size that use to encode the
strings as rough estimates of the percentage of performance gain from
this patch (UTF8 is missing because they cannot be externalized).
encoding 128KB 1MB 5MB
-----------------------------
ASCII 58% 208% 250%
HEX 15% 74% 86%
BASE64 11% 74% 71%
UCS2 2% 225% 398%
BINARY 2234% 1728% 2305%
BINARY is so much faster across the board because of using the new v8
WriteOneByte API.
v8 has a new API to write out strings to memory. This has been
implemented.
One other change of note is BINARY encoded strings have a new
implementation. This has improved performance substantially.
Before this commit NodeBIO never shrank, possibly consuming a lot of
memory (depending on reader's haste).
All buffers between write_head's child and read_head should be
deallocated on read, leaving only space left in write_head and in the
next buffer.
Commit 0bba5902 accidentally (or maybe erroneously) added node_isolate
to src/node.h and src/node_object_wrap.h.
Undo that, said variable is not for public consumption. Add-on authors
should use v8::Isolate::GetCurrent() instead.
I missed that while reviewing. Mea culpa.
Fixes#5639.
Remove the need to call start/stop the uv_idle spinner between
MakeCallbacks. The one place where the tick processor needs to be kicked
is where a user catches uncaughtException. For that we'll now use
setImmediate, which accomplishes the same task.
maxTickDepth checks have been removed for domains and replaced with a
flag that checks if the last callback threw. If it did then execution of
the remaining tickQueue is deferred to the spinner.
This is to prevent domains from entering a continuous loop when an error
callback also throws an error.
Removes the check for maxTickDepth for non-domain callbacks. So a user
can starve I/O by setting a recursive nextTick.
The domain case is more complex and will be addressed in another commit.
Previous code was calling uv_loop_delete() directly on a running loop,
which led to race condition aborts/segfaults within libuv. This change
changes the watchdog thread to call uv_run() with UV_RUN_ONCE so that
the call exits after either the timer times out or uv_async_send() is
called from the main thread in Watchdog::Destroy(). The timer/async
handles are then closed and uv_run() with UV_RUN_DEFAULT is called so
that libuv has a chance to cleanup before the thread exits. The main
thread meanwhile calls uv_thread_join() and then uv_loop_delete() to
complete the cleanup.
Quote from SSL_shutdown man page:
The output of SSL_get_error(3) may be misleading,
as an erroneous SSL_ERROR_SYSCALL may be flagged even though
no error occurred.
Also, handle all other errors to prevent assertion in `ClearError()`.
This saves a few calls to gettimeofday which can be expensive, and
potentially subject to clock drift. Instead use the loop time which
uses hrtime internally.
fixes#5497
Because of variations in different base64 implementation, it's been
decided to strip all padding from the end of a base64 string and
calculate its size from that.
Instead of String::New every time, use a Persistent sym. This can be
accomplished in two ways:
1) Local<String> str = *persistent_str_sym;
2) Handle<String> str = persistent_str_sym;
I've chosen to use the latter method for simplicity's sake.
Other small changes include creating syms on Initialize and removing
unnecessary Local casting on return values.
The default encoding is 'buffer'. When the input is a string, treat it
as 'binary'. Fixes the following assertion:
node: ../src/string_bytes.cc:309: static size_t
node::StringBytes::StorageSize(v8::Handle<v8::Value>, node::encoding):
Assertion `0 && "buffer encoding specified but string provided"'
failed.
Introduced in 64fc34b2.
Fixes#5482.
getServers returns an array of ips that are currently being used for
resolution
setServers takes an array of ips that are to be used for resolution,
this will throw if there's invalid input but preserve the original
configuration
This also templatizes the Buffer::*Slice functions, and the template
function probably cannot be safely used outside of Node. However, it
also SHOULD not be used outside of Node, so this is arguably a feature
as well as a caveat.
uv_async_t handles for dispatching of debug messages and
emitting NODE_DEBUG_ENABLED used to be initialized every time
node::EnableDebug() was called, which happened every time
user sends a SIGUSR1.
Now they are initialized only once from node::Init() during
application start.
Implement support for debugging cluster workers. Each worker process
is assigned a new debug port in an increasing sequence.
I.e. when master process uses port 5858, then worker 1 uses port 5859,
worker 2 uses port 5860, and so on.
Introduce new command-line parameter '--debug-port=' which sets debug_port
but does not start debugger. This option works for all node processes, it
is not specific to cluster workers.
Fixesjoyent/node#5318.
Add a watchdog class which executes a timer in a separate event loop in
a separate thread that will terminate v8 execution if it expires.
Add timeout argument to functions in vm module which use the watchdog
if a non-zero timeout is specified.
