uopz's Introduction

UOPZ

User Operations for Zend

The uopz extension is focused on providing utilities to aid with unit testing PHP code.

It supports the following activities:

Intercepting function execution
Intercepting object creation
Hooking into function execution
Manipulation of function statics
Manipulation of function flags
Redefinition of constants
Deletion of constants
Runtime creation of functions and methods

Note: All of the above activities are compatible with opcache

Requirements and Installation

If you use XDebug you need to use version 2.9.4 or higher.

See INSTALL.md

I've got "seagfault (core dumped)" when run this script https://gist.github.com/antonvolkov/b1ac2e4faad546d7278d with the same command "phpunit --repeat=10 UopzTest2.php"

By the way could you please clarify are you planning to make Uopz works with php7?

Thank you in advance

Install with composer is possible?

Can we have a version on packagist to install It with composer?

Support of magic methods redefining?

It would be nice to have ability to redefine magic methods.
Currently there is error message "will not override magic methods, too magical" occurs when trying to redefine one.

Are you going to implement this feature in future?
Or there are some critical impediments?

Problem with typehinted callable passed to uopz_add_function

Hello,

The following code:

class	dbClass {}

class	testClass
{
	static private function	db() : dbClass
	{
		return new dbClass();
	}
}

uopz_add_function(testClass::class, 'phpunit_db', static function() : dbClass { return self::db(); }, ZEND_ACC_PUBLIC | ZEND_ACC_STATIC);
$db = testClass::phpunit_db();

produces the following error:

PHP Fatal error: Uncaught TypeError: Return value of testClass::{closure}() must be an instance of , instance of dbClass returned in ...

Environment:

Array constant

Hello,

uopz_redefine() refuses to redefine a constant as array.

class	testClass
{
	const	ARR = [ 1, 2, 3 ];
}

uopz_redefine(testClass::class, 'ARR', [ 1, 2, 4 ]);

Results in:

PHP Fatal error: Uncaught RuntimeException: failed to redefine the constant testClass::ARR, type not allowed

Using master, following PHP environment:

Extends for final class, return of arbitrary class instance.

I am experimenting a little bit with uopz extension as weaving engine for implementation of aspect oriented paradigm in PHP by using proxies.

This seams perfect fit, in general it is possible to do it with "set mock" end "extends" functions, and it seams that it is possible to do it without modifying original source code.

However, two functionalities are missing

Possibility to remove "final" modifier from class in order to extend it in runtime, it would help generating proxies without modifying original source code.
In order to support "initialization" interception, it is required to have possibility to return arbitrary class instance for "new" keyword. This was possible in uopz for PHP v < 7, it is not possible now.

Stated 1. and 2. can be achieved as in GoAOP - by modifying original source code. However, it would be awesome if it could be supported by uopz, in that matter, AOP implementation in userland could be implemented much, much easier, and as it seams from initial experiments, it would be much more performant.

So, since I am not C developer and I don't have a knowledge about PHP internals, I was wondering if 1 and/or 2 are possible and if there are plans to implement those in future?

Thanks!

Allow returning an arbitrary object from the mocked "new" call

Feature request:

allow ZEND_NEW to be overloaded in such a way that it returns an arbitrary object coming from the overload callback (call to constructor is skipped unconditionally in such case)

I'd be happy to hear back if that feature fits the general roadmap of uopz.

Background story:

Wikia currently uses PHP 5.4 and with help of runkit + modified version of php-test-helpers (Wikia/php-test-helpers@9a28725) we were able to have a robust testing environment that satisfies our needs in the area of testing MediaWiki-derived code base.
As we're transitioning to PHP 5.6 we found out that uopz gives us all the functionality of the previous tandem in a single extension except the feature described above. We'd be very happy if we could get the missing piece implemented.

module can not be loaded on Windows Bitnami WAMP stack

I already tried to put zend_extension=php_uopz.dll before opcache and restarted the server but it always says Failed loading C:/Bitnami/wampstack-5.6.16-0/php/ext\php_uopz.dll but the file is there.

I tried php_uopz-2.0.7-5.6-nts-vc11-x64 and php_uopz-2.0.7-5.6-ts-vc11-x64 but still get the same error.

Is there something else we have to configure or change before this works? Any other requirements? Did someone else get it working under Windows?

Hey @krakjoe awesome extension, excited to start using it!

Currently it seems like xdebug breaks uopz when both are loaded (and load order doesn't matter) I didn't try a lot of stuff but the following exits with no output. (From the README)

<?php
uopz_overload(ZEND_EXIT, function($status = 0){});

class Test {
    public function method() {
        exit();
    }
}

class Unit {
    public function test() {
        $test = new Test();
        $test->method();

        return true;
    }
}
$unit = new Unit();
var_dump($unit->test());
uopz_overload(ZEND_EXIT, null);
var_dump($unit->test());
echo "failed";
?>

Is it possible to have two extensions in this area? (so I could submit a PR to xdebug/uopz) or do you know if the Zend VM was designed to only have one at a time.

thanks

Mocking new does not work properly in a few cases

The cases which appear not to be handled by uopz (php7):

new $variable
use Ns\X as Y; new Y;
uopz_set_mock('\\Ns\\X',....);

The issues are showcased in the code below:

a.php

<?php

class Foo {}
class Bar {}

$foo = 'Foo';
uopz_set_mock('Foo', 'Bar');

echo get_class(new Foo) . PHP_EOL;  // prints: Bar
echo get_class(new Bar) . PHP_EOL;  // prints: Bar
echo get_class(new $foo) . PHP_EOL; // prints: Foo - incorrect!

ns.php

<?php

namespace SomeNamespace {
    class NsFoo {}
    class NsBar {}
    class NsFoo2 {}
    class NsBar2 {}

    uopz_set_mock('SomeNamespace\\NsFoo', 'SomeNamespace\NsBar');
    uopz_set_mock('\\SomeNamespace\\NsFoo2', '\\SomeNamespace\\NsBar2');

    $nsfoo1 = 'SomeNamespace\\NsFoo';
    $nsfoo2 = '\\SomeNamespace\\NsFoo2';
    echo get_class(new NsFoo) . PHP_EOL;   // prints: SomeNamespace\NsBar
    echo get_class(new NsBar) . PHP_EOL;   // prints: SomeNamespace\NsBar
    echo get_class(new $nsfoo1) . PHP_EOL; // prints: SomeNamespace\NsFoo - incorrect!
    echo get_class(new $nsfoo2) . PHP_EOL; // printf: SomeNamespace\NsFoo2 - incorrect!
}

b.php

<?php

include "ns.php";

use SomeNamespace\NsFoo2 as Foox2;

echo '--- from b.php ---' . PHP_EOL;
echo get_class(new SomeNamespace\NsFoo) . PHP_EOL;  // prints: SomeNamespace\NsBar
echo get_class(new \SomeNamespace\NsFoo) . PHP_EOL; // prints: SomeNamespace\NsBar

uopz
uopz support => enabled
Version => 5.0.2-dev

I'd bet all of the constructor calls should return an object of one of the Bar classes but that's not the case as shown in the code even though I actually requested uopz to mock all the Foo classes.

Is it something that could be fixed?

exception from ZEND_EXIT overload

with older versions of uopz I used to be able to raise an exception from a ZEND_EXIT overload, which I would catch/expect in PHPUnit.
the latest changes seem to make this impossible, since I now have to return something from the overload function in order to continue execution.
is this change supposed to break behaviour? can I still throw exceptions in the overload somehow or do I have to refactor my testsuite?

Segmentation fault

Test case:

class Test {
    public $s = 'def';

    public function __construct($x) {
        $this->s = $x;
    }
}

uopz_function(Test::class, '__construct', function(){$this->s = 'redefined';});
var_dump((new Test('vvv')));

uopz_restore(Test::class, '__construct');
var_dump((new Test('vvv')));

$ php ~/1.php
/home/axp/1.php:12:
class Test#1 (1) {
  public $s =>
  string(9) "redefined"
}
Segmentation fault (core dumped)

php -i
strace

workaround is to use uopz_copy instead of restore:

$backup = uopz_copy(Test::class, '__construct');
uopz_function(Test::class, '__construct', function(){$this->s = 'redefined';});
var_dump((new Test('vvv')));

uopz_function(Test::class, '__construct', $backup);
var_dump((new Test('vvv')));

Compile guide?

Want a PR for a compile guide?

pretty much (at least on xenial)

Some ZEND_ACC_* constants have been removed in 5.0.0

The constants ZEND_ACC_CLASS, ZEND_ACC_INTERFACE and ZEND_ACC_TRAIT seem to have been removed in uopz 5.0.0, even though they appear to be still useful for uopz_flags($class, null, …) (at least 0 can be passed as $flags to "un-final-ize" a class in uopz 5.0.2). If these constants won't be re-introduced, I can fix the PHP manual accordingly.

Furthermore, obviously ZEND_ACC_FETCH has also been removed as of uopz 5.0.0. However, the constant is still mentioned in the README, what is rather confusing, particularly, as the $flags parameter of uopz_flags() apparently is now optional.

Setting hook on __invoke method doesn't work on call_user_func

PHP 7

class Handler {
    public function __invoke($arg)
    {
        echo $arg;
    }
}

uopz_set_hook(Handler::class, '__invoke', function (...$args)
{
    echo "hi!";
});

$h = new Handler();
$h(1); // works!
$h->__invoke(2); //work
call_user_func($h, 3); //doesn't

uopz breaks zend.assertions setting

Test script:

<?php
$testvar="a";
assert(is_bool($testvar), 'foo');
print "this is a test\n";

Without uopz

$ php -n -d zend.assertions=-1 foo.php 
this is a test

With uopz

$ php -n -d extension=uopz.so -d zend.assertions=-1 foo.php 
Warning: assert(): foo failed in /tmp/foo.php on line 5
this is a test

uopz breaks user-level session storage

Call to php_uopz_clean_user_function and php_uopz_clean_user_class in PHP_RSHUTDOWN_FUNCTION (uopz.c:690-691) removes all user-defined functions, including user-defined session storage handlers which may still be needed later in RSHUTDOWN for PHP's session module in order to write session data and close the session properly.

This results in bogus PHP Warning: "Unknown: Failed to write session data (user). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0" and breaks user-level session storage when uopz module is enabled.

tests/016.phpt incomatible with php 5.4

::class is 5.5 only

 sed -e s/A::class/"A"/ tests/016.phpt

solves this.

Unable to overload exit in PHP 5.5.14 and PHP 5.4.30

Test Script:

<?php

if (function_exists('uopz_overload')) {
    if (ini_get('uopz.overloads')) {
        echo "overloading exit()\n";
        uopz_overload(ZEND_EXIT, function(){});
    }
}
exit();

echo "This does not get output despite exit being overloaded.\n";

Output:

% php overload.php 
overloading exit()

Despite uopz being installed and overloads being enabled in php.ini, it simply doesn't work.

Do you have any pointers how to debug or fix this?

List Supported PHP Version(s)

I couldn't easily find the supported versions of PHP in the README, and while it might be obvious to some - or that a good majority of users are on 5.4 and above, for some of us unlucky folk who are stuck on 5.3 (stuck behind the 🎱 unfortunately) it would be nice to have that reminder that we need to affect change and upgrade our PHP version. :)

Mocking base class methods doesn't work properly

Hi!
It seems that it's impossible to mock base class method and get this method mocked in all derrived classes. Any workarounds?
Runkit is able to do such thing, btw.

opcache do not update class constant after uopz_redefine

see https://bugs.php.net/bug.php?id=74576

Description:

I use uopz_redefine to redefine class constants
(uopz called zend_declare_class_constant)

when opcache is enabled, I cannot get the new class constant through Foo::BAR.

Test script:

<?php

class Foo
{
	const BAR = '123';
}

var_dump(Foo::BAR);// A1: try to comment this

(function () {
	var_dump(Foo::BAR);	// B1: try to comment this
	uopz_redefine('Foo', 'BAR', '456');
	var_dump(Foo::BAR);	// B2: compare
})();

(function () {
	var_dump(Foo::BAR);	// new scope
})();

var_dump((new ReflectionClass('Foo'))->getConstant('BAR'));	// also OK

var_dump(Foo::BAR);	// A2: compare

Expected result:

'123'
'123'
'456'
'456'
'456'
'456'

Actual result:

'123'
'123'
'123' (it is '456' if line B1 is commented)
'456'
'456'
'123' (it is '456' if line A1 is commented)

uopz_set_return and uopz_set_hook apply to parents of class

class Bar {
    public function test() {
        return "Bar::test\n";
    }
}

class Foo extends Bar {
    public function test() {
        return "Foo::test\n";
    }
}

echo "Before set return\n";
echo (new Foo)->test();
echo (new Bar)->test();
uopz_set_return(Foo::class, 'test', "redefined return\n");
echo "After set return\n";
echo (new Foo)->test();
echo (new Bar)->test();
uopz_unset_return(Foo::class, 'test');
echo "After unset return\n";
echo (new Foo)->test();
echo (new Bar)->test();

output

Before set return
Foo::test
Bar::test
After set return
redefined return
redefined return
After unset return
Foo::test
redefined return

same with uopz_set_hook

block optimization (opcache) fails when exit is overloaded

<?php
class Uopz_Test extends PHPUnit_Framework_TestCase
{

    public function testExit()
    {
        uopz_overload(ZEND_EXIT, function($status = 0) { return false; });
        exit();
        uopz_overload(ZEND_EXIT, null);
    }

}
?>

Still researching the problem ... this bug is present only in the last release (2.0.7)

Unconditional exit code overloading

This is just a @alexjay 's comment copy from #2

I expiriencing the same trouble with uopz 2.0.6. Exit code spicified in exit() is missing.

How to reproduce:

enable uopz

zend_extension=uopz.so

create test.php file with exit

<?php
exit(42);

run it

php test.php; echo $?

expected is 42
actual is 0

Exit code will be 0 regardless the value that was specified in the script.
I've tried to remove php_uopz_overload_exit at zend extension initialization and recomplie the uopz extension... and it helped. It seems that the default exit() uopz handler misses its exit code.

We simply removed exit overloading from uopz since we don't need it so far, but others can experience the same problem even not noticing it. So proper patch would be nice.

uopz doesn't work on Windows if a replaced function was called before from a function

The following code that works perfectly fine on Linux (output should be a random byte in hex and then ffffffff) does not work on Windows (PHP 5.6.14, tried both x64 and x86, TS and NTS builds, enabled and disabled opcache, uopz binary 2.0.7 from https://pecl.php.net/package/uopz).

<?php

function printRandomByte() {
    echo bin2hex(openssl_random_pseudo_bytes(1)) . "\n";
}

printRandomByte();
uopz_backup('openssl_random_pseudo_bytes');
uopz_function('openssl_random_pseudo_bytes', function($length, &$strong = null) {
    return hex2bin('ffffffff');
});
printRandomByte();
uopz_restore('openssl_random_pseudo_bytes');

It just outputs two random bytes instead (as if the openssl_random_pseudo_byte function wasn't replaced at all).

If I remove the first printRandomByte() call before the uopz_backup, then it works. If I remove the first call plus add a printRandomByte() call after the uopz_restore, PHP crashes.

If I replace the printRandomByte(); calls with just the function body (echo bin2hex(openssl_random_pseudo_bytes(1)) . "\n";), then it works as it should.

It behaves similarly for other functions (I also tried time())

Test failing on PHP 5.4.39 on CentOS

I installed uopz using the pecl installer. In phpinfo() it seems to be installed perfectly. Then I added uopz.overloads=1 in php.ini.

Then I tried to run the first test and it worked well.
But the second test fails.

Here is my PHP code:

uopz_overload(ZEND_FETCH_CLASS,
    function (&$class) {
        if ($class == "stdClass") {
            $class = "myClass";
        }
    });

class myClass {
}

$class = new stdClass();
var_dump($class instanceof myClass);
uopz_overload(ZEND_NEW, null);
$class = new stdClass();
var_dump($class instanceof stdClass);

Output is:

boolean false
boolean true

The anonymous overload function does not get executed.

Have I configured something wrong?

Segfault after uopz_set_static()

Running this causes an invalid read in both current PHP 7.1 and 7.2:

<?php
class A {
    function fn() {
        static $a = 1;
        $a++;
    }
}

print_r(uopz_get_static(A::class, "fn"));
uopz_set_static(A::class, "fn", ['a'=>3, 'b'=>7]);
$a = new A;
$a->fn();
print_r(uopz_get_static(A::class, "fn"));

The gdb output from PHP 7.2 is:

Array
(
    [a] => 1
)

Program received signal SIGSEGV, Segmentation fault.

Request: Tagged release

last release is quite a while back and isn't building against 7.1 for a lot of people.
A new "convenience release" as you called it for 5.0.1 would be much appreciated.

Installation error

Hi,
I'm trying to install uopz inside my OSX(Sierra) with php7.1

I have done this:

sudo pecl install uopz

But it can't install and this is the output of some errors, how can I install this extension?

call_user_func() ignores uopz_set_return hooks

If a hook is set via uopz_set_return() it is called when the function is called directly or as variable function as desired. However, calling the function via call_user_func() circumvents the hook, and calls the original function instead.

Reproduce code:

function foo() {echo 1;}
uopz_set_return('foo', function () {echo 2;}, true);
foo(); // => 2 
$f = 'foo';
$f(); // => 2
call_user_func('foo'); // => 1

Crash on module shutdown

Hi,

I'm experiencing a crash in uopz with php 5.4.28 & uopz 2.0.4.
Basically I'm just adding uopz.so without calling any uopz function, and it crashes :

Program received signal EXC_BAD_ACCESS, Could not access memory.

uopz_set_mock hangs when using an anonymous class as mock

When uopz_set_mock is called with an anonymous class as the mock, attempting to instantiate that class with an argument to the constructor causes the process to hang.

Minimal reproduction:

<?php
class X {}
uopz_set_mock(X::class, new class { public function __construct() {} });
$x = new X(0);

uopz support => enabled
Version => 5.0.2

I cannot reproduce this with xdebug on, but I assume that is actually just issue #61.

phpmd breaks once uopz.overload=1 is set

If the uopz is installed and uopz.overloads = 1 is configured, phpmd breaks:

[vinai@Sayyadina:/usr/local/etc/php/5.6/conf.d on master]
% cat ext-uopz.ini

Once uopz.overloads is not set (or the uopz extension is removed completely) phpmd works fine.
The same behavior can also be found in php 5.5.25.

Do you have any idea what in phpmd might cause this issue or how to work around it? I would really like to use both phpmd and uopz.overload in CI.

Since I don't know if this or phpmd is a better repository to report the issue I've cross posted here: phpmd/phpmd#284

Function uopz_set_mock don't work when Xdebug extension is loaded

test code:

<?php

class A1 {
  public function test() {
    print "a1\n";
  }
}

class A2 {
  public function test() {
    print "a2\n";
  }
}

uopz_set_mock('A1', 'A2');

$a = new A1();
$a->test();

print get_class($a) . "\n";

output:

a1
A1

expected output:

a2
A2

Handle to the original function/method?

Use case:

uopz_set_return(Foo::CLASS, 'myMethod', function(...$args){
    echo "entering myMethod with args:\n"
    print_r($args);

    // $_ is an handle to the "decorated" method/function
    // basically the original Foo::myMethod
    $result = $_(...$args);

    echo "leaving myMethod with return:\n";
    print_r($result);

    return $result;
}, true) : bool;

Would this be possible?
Thanks.

Breaking PHPRedis connect

Hi,

I am simply trying to grab the params used in the method of the Redis class.

Here is my code:

        uopz_backup('Redis', 'connect');
        $redisConnect = uopz_copy('Redis', 'connect');

        uopz_function('Redis', 'connect', function($ip, $port, $timeout, $a, $b) use ($redisConnect)
        {
            var_dump('================================================');
            var_dump('================================================');
            var_dump('================================================');
            var_dump($ip);
            var_dump($port);
            var_dump($timeout);
            var_dump($redisConnect($ip, $port, $timeout, $a, $b));
            var_dump('================================================');
            var_dump('================================================');
            var_dump('================================================');

            return $redisConnect($ip, $port, $timeout, $a, $b);
        });

I tried this code without uopz_backup function. But it did not change anything.

Here is the first error I get. It seems it is the uopz_copy function that is throwing it.

Warning: Cannot bind function Redis::connect to object of class Mindray_Core_Hooks

The following error I get is this:

Fatal error: Uncaught exception 'DataProvider_Exception' with message 'All servers timed out'

So clearly using this code causes the PHPRedis to not connect. When I take out the code everything is fine. So it is this code that is the source of the problem.

What am I doing wrong?

Thanks in advance for any help.
