I am experiencing memory leaks using v8js with PHP 5.5 and mod_php.
<?php
$v = new V8Js;
With a simple php file that creates a V8Js
instance, I see memory used by apache increasing on every request. I also see the thread count increasing every request.
Making 100 requests to this simple script takes the memory usage from 1.1MB to 234.5MB. I see the thread count go from 1 to 506 threads.
Hi all,
pulled latest v8 from github, installed, copied all headers and libs, make fails with the following output:

any clue? )
It would be great if the README stated which version of v8 was known working by the developers. I was trying with v8 3.22.5 with a bunch of errors.
The following code runs as expected in PHP 5.3.3 but crashes PHP 5.4.4
<?php
class V8Wrapper extends V8Js {
public $testing; // remove line to make it work :-)
public function __construct() {
parent::__construct();
$this->testing = 23;
}
}
$v8 = new V8Wrapper();
$v8->executeString("print('foo');");
Backtrace of crashed PHP 5.4.4 instance:

If the public $testing;
property declaration is removed from the code everything works well, even with PHP 5.4.4
I probably will have a go to fix this, but do we want to fix this, or do you consider it expected behaviour? (after all it shouldn't crash no matter what)

I have had a lot of trouble compiling on OS X using the method described in the readme.
I have got it working with the following instead (requires g++-4.7).
cd /tmp
git clone https://github.com/v8/v8.git
cd v8
make dependencies
export CXX=/usr/local/bin/g++-4.7
export LINK=/usr/local/bin/g++-4.7
make native component=shared_library snapshot=off -j8
# Important to turn snapshot off
sudo mkdir -p /tmp/v8-install/lib /tmp/v8-install/include
# Copy the dylib as an "so" doesn't get built
sudo cp out/native/lib*.dylib /tmp/v8-install/lib/
sudo cp include/v8* /tmp/v8-install/include
cd /tmp
git clone https://github.com/preillyme/v8js.git

Just to let you know, v8 API has changed once more breaking V8Js.
Will have a look the next days if noone else has a look.
Hi there,
if I call a PHP function from JavaScript context and the PHP function returns a object, the object seems not to be correctly garbage collected even if the passed back object is not stored at all.
Code snippet to reproduce:
<?php
ini_set("v8js.flags", "--trace_gc");
$v8 = new V8Js();
class Failer {
function call() {
return new stdClass();
}
}
$v8->failer = new Failer();
$v8->executeString('
for(;;) {
PHP.failer.call();
}
');
... after running for some twenty seconds the memory consumption hits roughly 1,5 GB, then the loop performs very poorly and v8 garbage collects on almost every instruction ... however it doesn't get rid of all those objects ...
No problem if you pass back an array or immediate values from the function though ...
I've just started using v8js the other day, neither am I a PHP "backend" developer, hence I currently have no clue on how to fix that...
cheers

V8Js::executeString() now compiles and runs scripts each time it's called. It might be worth to add a V8Js::compileString() method which returns a resource for the compiled script and a V8Js::runScript() function to execute them.
I am new to v8js and trying it out today for the first time. I'm running CentOS 6.4 64-bit with PHP 5.5.4. I followed the instructions listed in README.md to compile the latest versions of both v8 and php-v8js, but when compiling php-v8js, I'm getting the below error. I just pasted the first few errors, but a list of them occurs. Can you please let me know what might be causing it? Please also let me know if I can supply more information. Thanks for your help.

The V8Js object is treated as a special case, and has its own handlers both on the V8 and the PHP sides. Now that V8 wrapping of PHP objects works much better (since f6a6d1e) I think it makes sense to remove a bunch of this code and just expose the V8Js object using the standard zval_to_v8js
wrappers.
However, there are some methods of the V8Js object which we don't want to directly expose to JS (like the executeString
method), so I'm actually proposing that the V8Js object reference a separate "blank" object for user properties. Adding/removing/querying properties from the PHP side would be proxied over to the user properties object. The V8 wrapper for V8Js would be the standard zval_to_v8js of the user properies object.
I think that would end up removing a bunch of now-redundant code (like all of v8js_variables.cc
) and simplifying the codebase (like php_v8js_write_property
etc).
Hi!
Is it possible to persist V8 instance between requests in web server? I found old issue on this topic #4 and seems it was impossible back than. Do you have plans to implement it? I think it would be useful feature, like persistent connections in mysql extensions.
Hi guys, for some time I've been playing with deb packaging and there's a question:

What am I doing wrong?
Thanks a lot
The following code sample is the minimum required to reproduce the problem. As you can see, the problem occurs via __get and via an existing method.
I'm testing with PHP-5.3.10 and libv8.so version 3.17.13.
<?php
class Service
{
public function method()
{
print("method\n");
}
}
class Container
{
private $service = null;
public function __get($name)
{
if ($name == 'crash') {
return new Service;
} else {
$this->service = new Service;
return $this->service;
}
}
public function getService()
{
return new Service;
}
}
$v8Js = new V8Js('PHP');
$v8Js->container = new Container;
$code = <<<EOT
var container = PHP.container;
// This works OK
//container.ok.method();
// These both cause seg fault
container.crash.method();
container.getService().method();
EOT;
$v8Js->executeString($code, 'test');
The seg fault happens during the zend_get_class_entry (via Z_OBJCE_P) call in the php_v8js_php_callback function (line 46 in v8js_convert.cc).
I have limited knowledge of Zend internals, but this looks like an object referencing issue. The pointer that is passed into Z_OBJCE_P is coming via the SetAlignedPointerInInternalField. Perhaps we need to explicitly add a reference to the object and use that in the SetAlignedPointerInInternalField call instead?
I'm willing to help fix this if anybody can provide any insights into why this might be happening.
Hi, I'm trying to compile v8js for my php on a windows platform, but so far failed. I don't much experience of compiling from source, can a guide be created for compiling V8js on windows?
It would be nice to have a released version with the time/memory limits!
Hi again :-)
got another one, inspired by the function template thing ... the objects passed back to from PHP to JavaScript have a constructor attribute pointing to the constructor function (i.e. function template from before). If you call that one in JavaScript you get fresh extra objects, ... however if you call back to PHP everything crashes since v8js relies on the internal fields, which are not initialized however.
Example code, first showing use of constructor attribute in JavaScript, then with PHP & JavaScript in combination:
$v8 = new V8Js();
class Greeter {
function sayHello($a) {
echo "Hello $a\n";
}
}
$v8->greeter = new Greeter();
$v8->executeString('
function JsGreeter() { };
JsGreeter.prototype.sayHello = function(a) {
print("Hello " + a + "\n");
};
jsGreeter = new JsGreeter();
jsGreeter.sayHello("Paul");
jsGreeterNg = new jsGreeter.constructor();
jsGreeterNg.sayHello("George");
// ----- now the same using v8Js -----
PHP.greeter.sayHello("John"); // prints "Hello John" as expected
print(PHP.greeter); // prints "[object Greeter]" as expected
print("\n");
// What about the constructor function of greeter?
print(PHP.greeter.constructor);
// ... yields "function Greeter() { [native code] }"
// ... super, so let me create more greeters
var ngGreeter = new PHP.greeter.constructor();
ngGreeter.sayHello("Ringo"); // well, segfaults
');
cheers,

Hi,
I'm planning to use your library for triggers / data processing, and it would be nice to have time limiting (and probably memory limiting, which is not that important).
This can be passed to executeString as an array of options after $flags parameter. Also, I can try to pullrequest if you can point where to change, but my C knowledge is not that good )
Hello,
I'd need to persist the v8 object so that I do not need to instantiate
and process the javascript scripts from PHP during every http request. Is that
possible?
I have tried using apc_store to store in memory the v8 object but when I fetch
it from the cache then when I try to use it I get:
PHP Fatal error: V8 not initialized in
I'd like to think about the cleanup of php_v8js_ctx some more. I think it might be possible for the ctx to be deallocated before all of the objects created in that context have been dereferenced -- like if you return a javascript object to PHP, store it in a property somewhere, and then the V8JS object falls out of scope. Any ideas on how best to handle that situation? Maybe we should ref the V8JS object whenever we create a new PHP wrapper of a JS object? V8 also has some "object group" features which might be relevant.
I am trying to use php to retrieve a html page via curl
Is there a way to execute the whole html page & JS of the curl response via v8js so you can get access to the env variables? of the page?
We need to call v8::V8::InitializePlatform
on startup now and v8::V8::ShutdownPlatform
on shutdown.

Once an extension is loaded with registerExtension, is there a way to unregister an extension or overwrite it with new JS code? I was able to do it by restarting apache, but is there another way that it can be done that doesn't require restarting apache? Thanks for your help.
Hello,
My name is Fernando and I installed the extension v8js in my PHP 5.3.10-1ubuntu3.6
But when i try to set the memory limit e time limit it doesn't work.
I'm using the following scripts that i found in the repository at github for test:
v8js / tests / memory_limit.phpt
v8js / tests / time_limit.phpt
This is the link of my phpinfo: http://198.199.111.114/teste03.php
For Example:
executeString($JS, 'basic.js', V8Js::FLAG_NONE, 0, 10000000)); } catch (V8JsMemoryLimitException $e) { var_dump($e); } ?>Result: Null
executeString($JS, 'basic.js', V8Js::FLAG_NONE)); } catch (V8JsMemoryLimitException $e) { var_dump($e); } ?>Result: endint(3)
Note: I switched var_dump($v8->executeString($JS, 'basic.js', V8Js::FLAG_NONE, 0, 10000000)); to var_dump($v8->executeString($JS, 'basic.js', V8Js::FLAG_NONE));
I downloaded the files from repository on github and i tried to compile and install (phpize,./configure, make, make install) v 0.1.4.
But when i execute the command make, I get the following error:
make: *** [v8js.lo] Error 1
I also tried to download from pecl (http://pecl.php.net/get/v8js-0.1.3.tgz) and compile/install and everything worked ok.
This is the link of file with the output of the command make:

I am looking at your v8 engine for PHP and it looks very promising, however I am not able to find any more details about your quote:
“The extension allows you to execute Javascript code in a secure sandbox from PHP. The executed code can be restricted using a time limit and/or memory limit. This provides the possibility to execute untrusted code with confidence.”.
I am mainly interested how secure this environment is. For example is it possible for the JS to include external libraries which in turn may be able to access the disk or the network? How safe would I be to expose a scripting interface in my a control panel, what is the worst types of scripts that can be ran from this. Are there any other methods of controlling the security level?

We currently test against 3.21.12, so this should work...
I'm trying to set up a server-side LESS compiler using V8Js, but I can't load less.js because it initially attempts to interact with the DOM.
Once less.js is initialized, I can easily compile less using its built-in functions - but getting past that initialization process isn't possible without a DOM for less to interact with.
I found jsdom, but I'm at a loss to figure out how to load it in the V8Js environment as it uses require to load pieces of itself.
The Travis configuration doesn't seem to check for test suite errors correctly.
See build output of https://travis-ci.org/stesie/v8js/builds/12743962 (I'm currently preparing another pull request, which broke the PHP 5.3 build however)

I tried some workarounds to this, like removing the locking before calling IdleNotification in php_v8js_free_storage but that results in memory leaks. Adding v8::TerminateExecution before IdleNotification doesn't help either. I also tried moving the whole script->Run() into a new thread, but basically the code never returns from it.

Some functions doesn't work with default parameters (see result.fetchArray())
<?php
$script=<<<EOT
PHP.sql.exec('CREATE TABLE foo(bar STRING)');
PHP.sql.exec('INSERT INTO foo(bar) VALUES("test")');
var result=PHP.sql.query('SELECT bar FROM foo');
while(data=result.fetchArray()) {
print(data.bar, "\\n");
}

$foo = $v8js->executeString("String.fromCharCode(65)");
var_dump($foo);
$foo = $v8js->executeString("String.fromCharCode(0)");
var_dump($foo);
Since both JS and PHP can handle strings with NULL-bytes I would expect even the latter to return a string of one byte length, ... well but:
string(1) "A"
string(0) ""
Hi,
Not sure if this is intended behaviour or not, but it seems like a regression given the number of test cases that have comments saying private/protected properties shouldn't be accessible from the JS side.
Test code:
<?php
class Foo {
private $privBar = "privBar";
protected $protBar = "protBar";
public $pubBar = "pubBar";
}
$js = new V8Js();
$js->foo = new Foo();
$script = <<<END
print(PHP.foo.privBar);
print(PHP.foo.protBar);
print(PHP.foo.pubBar);
END;
$js->executeString($script);
This prints all three strings instead of throwing an error or printing undefined for the non-public ones.

If this is the desired behaviour, would it be possible to allow configuring this? From my point of view it's not desirable to expose priv/prot properties from PHP classes to JS.
Thanks,

Issue #31 added a test case which demonstrates the problem, but it hasn't been fixed yet.
The following code:
$v8 = new V8Js();
$v8->executeString("var foo='bar';");
$v8->executeString("print(foo)");
...prints bar
-- that is, the variable foo
is retained between invocations of executeString
. Further, foo
then leaks if it's a reference to a PHP object, for example:
class Bar { }
$v8 = new V8Js();
$v8->bar = new Bar;
$v8->executeString("var foo=PHP.bar;");
Somehow we're not cleaning up the v8 global object when the V8Js object is destroyed.
We should do that -- perhaps even doing that between executions of executeString
, as I'm not sure that behavior in the first code example is not a bug. Maybe this is as easy as wrapping executeString
's execution in a new v8 scope so it's not running in global scope? Perhaps we also want to define a globals
object like node does which exposes the global scope if you want to share context between executeString
calls.
I'm using v8->executeString
to evaluate some code like:
(function(exports) {
// begin module code
exports.hello = function() { return 'hello' };
// end module code
return exports;
})({})
That's a pretty standard wrapper for a CommonJS-style module definition. I get the exports
object back in PHP land. I'd like to then call various (JavaScript) methods from it. But $exports->hello()
gives me a V8 exception ("v8::HandleScope::CreateHandle() Cannot create a handle without a HandleScope"), and the other various ways I've tried to do this, like:
$v8->func = get_object_vars( $exports )['hello'];
$result = $v8->executeString("PHP.func()");
gives me complaints in JS land that func
is "not a function" (it's a [object V8Function]
apparently). What am I doing wrong?

make: *** [v8js.lo] Error 1
... which seems to be caused by commit 8d8c671, which passes v8::Isolate
to v8::HandleScope::HandleScope
From v8's ChangeLog:
2013-03-15: Version 3.17.11
Added a version of the v8::HandleScope constructor with an v8::Isolate
parameter and made AdjustAmountOfExternalAllocatedMemory an instance
method of v8::Isolate.
(issue 2487)
... hence I ask you to please update the README to reflect the requirement.

Is it possible to use a static build of the libv8 to build php-v8js. This would be very useful as the required libv8 version is not even included in recent linux distributions (like Ubuntu 14.04). Therefore a simple installation via pecl or similar is not possible.
As the following code shows there seems a few properties from the object missing. PHP returns '1'. V8 returns 'undefined'.
loadXML(''); $elements=$dom->getElementsByTagName('node'); echo $elements->length, "\n"; $v8=new V8Js(); $v8->dom=$dom; $v8->executeString($script); ?>Thank you for a very useful extension. Would it be possible to add an executeFile() method that works just like executeString() except it takes a filename as its first argument? This would avoid having to call file_get_contents when the javascript to execute is in an external file.
For example, rather than doing:
$v8->executeString(file_get_contents('test.js'));
executeFile would allow calls like:
$v8->executeFile('test.js');
Thanks.
Currently we require v8 version 3.22.3 or newer, however older ones aren't actively maintained by Google. I think it's a bit intransparent which versions are actively maintained, according to https://code.google.com/p/v8/wiki/Source usually the last two branches.
According to http://omahaproxy.appspot.com/ currently stable Google Chrome browser uses v8 version 3.27.34.17
So almost certainly there's no maintenance for 3.26.x and earlier and we currently have a whole lot of preprocessing macros to achieve compatibility with those rather old versions. Especially the V8JS_NEW, V8JS_INT, V8JS_UINT and V8JS_DATE ones are really ugly ... and could be dropped, if we require 3.27.0 or newer ..
I don't see any reason why to support older versions and would step up and remove that glue stuff.
Any objections? @preillyme @rosmo @cscott
(and after all, someone who needs a older v8 version could pick a slightly older v8js, i.e. current master)
Shouldn't be hard to write, but there's a // Not implemented yet
comment in v8js.cc

I ran into this while trying to use PHP's property_exists
method on an object returned to PHP from JavaScript.

make: *** [v8js.lo] Error 1
when searching for the error on Google, I found a link to #19 but none of the solution I found there worked.
I just stumbled across #84 which looks very much like it, but I am already building all this on bash.
Oh and if that can help : Ubuntu 14.04 LTS 64b
I can't install v2js on OpenSuse 11.2, there is no way to update gcc to 4.6+ version, and the early ones do not support C++11.
Can you make a patch for install it with gcc < 4.6 (4.4.1 for example)?
Thanks!
I'm getting error when try make php-v8js.
I'm using gcc version 4.8.1.
Versions of v8 library which I used to install: 3.20-3.24.
(Ubuntu 13.10, PHP 5.5.3-1)
Also I used gcc 4.7.3 but had same result. Install via pecl fails too.
What release and version of gcc I must use to install it correctly?
