Zephir is a compiled high-level language aimed to ease the creation of C-extensions for PHP

zephir's Issues

Performance of compiled extension

I want to start off with saying I'm a very performance oriented person when it comes to my code. Which is the number one reason for my interest in Zephir. Also, this is less of a bug, and more of an issue/area of concern.

I decided to make a side-by-side comparison of execution times between an extension compiled with Zephir and native php code.

To make my test, I first wrote my php function. It's a simple function only 28 lines long, that takes a router signature string (to define a route in a framework) and compiles it into a regular expression. I then literally copy and pasted the php function into a zep file, altered the php accordingly to become zephir code.

so now I have these two identical functions, one in native php, and one in a compiled extension.

I then made a script to run each of them 1000 times (with the same signature, it was just a simple for loop)

What I saw kind of blew my mind... the php code was consistantly outperforming the compiled code!

I'm seeing results like the following:

PHP Execution Time 0.24159812927246s
Compiled Execution Time 0.28048205375671s

That was on my little machine dedicated to Zephir work. so then i compiled the extension on my big server and ran the tests.. still it's the same deal (though the time is lower, the difference is about the same)!

PHP Execution Time 0.071985960006714
Compiled Execution Time 0.075214147567749

I think it's important to point out that in my code, I'm calling the following php functions (which means that the compiled code is calling them also):

trim() x 5
explode() x 1
substr() x 6

If anyone would like to see my code just let me know, maybe i'm not writing my Zephir code "correctly"

While loop not working with evaluated expression

I have the following block of code (echoes added for diagnostic purposes)

    private function getTrieNodeByKey(string key, create = false)
    {
        var trieNode, keyLen, i, character;
        let trieNode = this->trie;
        let keyLen = strlen(key);
        let i = 0;

echo "key = [", key, "]", PHP_EOL;
echo "keyLen = [", keyLen, "]", PHP_EOL;
echo "i = [", i, "]", PHP_EOL;

        while (i < keyLen) {
echo "In while loop", PHP_EOL;
            let character = substr(key,i,1);
            if (!isset(trieNode->children[character])) {
                if (create) {
                    let trieNode->children[character] = new tries\trienode();
                } else {
                    return false;
                }
            }
            let trieNode = trieNode->children[character];
            let i += 1;
        }

        return trieNode;
    }

which compiles successfully, but the while loop is never executed

The output I get is:

key = [adder]
keyLen = [5]
i = [0]
key = [addled]
keyLen = [6]
i = [0]
key = [advance]
keyLen = [7]
i = [0]

As you can see, the In while loop message is never displayed, despite the fact that the keyLen and I values clearly show that it should be

The only way I've been able to get this to work is to evaluate an intermediate variable j, but that is more of a workround.

Is there any syntax I can use to handle the evaluated expression in the while itself?

What version of php we need to support?

Hi
In commit i failed on $variableVariable->getClassTypes()[0]
because this simple code supports on php 5.4 >=
I think we need on run see php language and if if < 5.4 exception on it and write this requriment in docs

Not cached method call in validation.zep

In the Validation:

for scope in validators {

        if typeof scope != "array" {
                throw new Phalcon\Validation\Exception("The validator scope is not valid");
        }

        let attribute = scope[0],
                validator = scope[1];

        if typeof validator != "object" {
                throw new Phalcon\Validation\Exception("One of the validators is not valid");
        }

        /**
         * Check if the validation must be canceled if this validator fails
         */
        if validator->validate(this, attribute) === false {
                if (validator->getOption(cancelOnFail)) {
                        break;
                }
        }
}

validate() method of Validator is cached:

validator->validate(this, attribute)

is converted to:

zephir_call_method_p2_cache(_0, validator, "validate", &_4, this_ptr, attribute);

and always validate first Validator in the scope. How to call not cached method zephir_call_method_p2? This issue is related to phalcon/cphalcon#1696

Increment/decrement operator not working as expected on object property?

The documentation at http://zephir-lang.com/control.html#let suggests that the increment and decrement operator can be used on an object property. However, I've found with a very simple test that this doesn't appear to be so.

My simple test class (which is basically the 'hello world' from the tutorial), php calling code and results are be seen here:

https://gist.github.com/amnuts/8633535

In essence; neither of these work:

let this->counter1++;
let this->revcounter1--;

These always produce the value 1:

let this->counter2 += 1;
let this->revcounter2 -= 1;

These reliably work:

let this->counter3 = this->counter3 + 1;
let this->revcounter3 = this->revcounter3 - 1;

This is using Zephir 0.3.0a.

Incorrect class name

Zephir code is....

namespace magento;

final class Mage {
    static private _app;
    static private _events;

    public static function app(code = "", type = "store", options = []) {
        let self::_app      = new Mage_Core_Model_App();
        let self::_events   = new Varien_Event_Collection();

        Varien_Profiler::start("self::app::init");
        Varien_Profiler::stop("self::app::init");

        return self::_app;
    }
}

when compiling zephir code above, I got this error.

[hopsoed@localhost]$ zephir compile
Type=ternary
int
CompilerException:
Incorrect class name: Varien_Profiler in /var/www/shell/zephir/magento/test.zep on line 12

          Varien_Profiler::start("self::app::init");
        -------------------------------------------^

what is the problem ?

[NFR] Obfuscation

What would be really nice in zephir is a way to obfuscate variables so that they won't be visible as raw string in binary extension thus preventing from easy reverse-engineering.

Imagine you have something that you need to distribute with your application but need to keep it secret. Like a RSA public keys or some API keys.

Currently one can define these in following way:

class Secret {
   const RSA_PUB_KEY = '------ PUB KEY -------\nBlaBlaBla';
   private _apiName = 'secret Login';
   private _apiKey = 'secret Password';
}

However, both will be visible from compiled binary extension in hex mode.
The nice way, for instance could be something like:

class Secret {
   const obf RSA_PUB_KEY = '------ PUB KEY -------\nBlaBlaBla';
   private obf _apiName = 'secret Login';
   private obf _apiKey = 'secret Password';
}

Before compilation a zaphir macro would obfuscate variables declared in such way.

I don't want to start discussion on how safe this is, as almost everyone armed with debugger or reflection would be able to reverse-engineer it (unless there's some technique to prevent this I'm not aware of) but it's a nice and easy way to stop 99% of attacks at the application.

It might or may not be a good way to make things safer and a good alternative to Zend Encoder or IonCube.
It could be opensource or a paid add-on for Zephir you could use to make money on it.

What are your thoughts on this?

Can't call function "eval()" in php

while i'm try this code in .zep:
.....
eval("echo 'hahaha';");
...

i recieved error:

"Warning: Function "eval" does not exist at compile time in /root/zephir/utils/utils/Greeting.zep on 44 [nonexistent-function]"

please fix this error!
thanks

mb_strpos($string, "\x00") (as well as strpos) causes warning Empty delimiter

Subject. When I edit C source directly, wrapping "\x00" as '\x00' or '\0', I get segmentation fault after compilation.

Cleaning up the ext directory

Would it be ok if I moved the clean and install files to templates? Also, the ext/kernel directory could be moved to template and the ext directory cleaned up from the repo and git-ignored? It would be rebuilt on the next zephyr command anyway. I think it might look cleaner at the end.
I imagine the final hierarchy as being something like that:

zephir
  |- bin
  |- Library
  |- parser
  |- scripts
  |- tempates
  |- test
      |-ext
      |-test (all test zep files)
      |- unit-tests (all test php files)

Please let me know if it's ok

Creating classes with the same name as a Zephir type

Suppose you want to make a class that represents a data type:

    class Boolean {}

This throws a ParserException:

    ParseException: Syntax error in /path/to/my/extension/Boolean.zep on line 3

    class Boolean
    -----------^

Do while loop

I would like to use do while loop:

do {
    let key = key(variable);
    let value = current(variable);
} while next(variable);

but I've got the message:

Call to undefined method CodePrinter::outputLineBreak() in ../zephir-master/Library/Statements/DoWhileStatement.php on line 49

Branch prediction operators

if unlikely empty this->checkKnownWords([word]) {
    // do something
} else {
    // do something else
}

Trying to do something like this (or even with the empty() function from PHP) seems to kill the branch entirely (it switches to "something else" even when the condition evaluates to TRUE. If I remove unlikely, it all works as expected.

windows support: add equivalents of bash scripts and more

re2c and json-c are both available there, so it should not be too much of an hassle to port...

make zephir installable via composer

to give it wider adoption, being installable via composer is a must.
Imho a composer.json file and registration on packagist.org would be nice - even if there is still a compilation step involved after download

instanceof does not transverse the hierarchy

If we have a class hierarchy such as:

interface I {}
class A implement I {}
class B extends A {}

Then the following returns false:

let b = new B();
b instanceof A;  // evaluates to false
b instanceof I;  // evaluates to false

This returns true:

b instanceof B  // evaluates to true

Is that the expected behaviour?

Thanks

[Parser] Wrong parser

We have many problems about lexer parser and wee need tests for it.

Example

if (!empty(eventName) && isset(this->events[eventName])) {

generate

array(5) {
  'type' =>
  string(5) "empty"
  'left' =>
  array(6) {
    'type' =>
    string(3) "and"
    'left' =>
    array(5) {
      'type' =>
      string(4) "list"
      'left' =>
      array(5) {
        ...
      }
      'file' =>
      string(61) "/media/projects/ZephirEvm/cyant/eventmanager/eventmanager.zep"
      'line' =>
      int(147)
      'char' =>
      int(32)
    }
    'right' =>
    array(5) {
      'type' =>
      string(5) "isset"
      'left' =>
      array(5) {
        ...
      }
      'file' =>
      string(61) "/media/projects/ZephirEvm/cyant/eventmanager/eventmanager.zep"
      'line' =>
      int(147)
      'char' =>
      int(64)
    }
    'file' =>
    string(61) "/media/projects/ZephirEvm/cyant/eventmanager/eventmanager.zep"
    'line' =>
    int(147)
    'char' =>
    int(64)
  }
  'file' =>
  string(61) "/media/projects/ZephirEvm/cyant/eventmanager/eventmanager.zep"
  'line' =>
  int(147)
  'char' =>
  int(64)
}

but works like

if ((!empty(eventName)) && isset(this->events[eventName])) {

Error while generating phalcon 2.0

I get this error

PHP Fatal error: Can't inherit abstract function CommandInterface::getCommand() (previously declared abstract in CommandAbstract) in /home/xxxx/Downloads/zephir/Library/Commands/Abstract.php on line 26

I know phalcon 2 is not support and all, but do you have an idea what might be the problem ? (i'm on centOS 6, PHP 5.3.3 (cli))

I followed this guide https://github.com/phalcon/cphalcon/tree/2.0.0

if empty

When I, for example, create successfully socket with fsockopen, statement 'if empty socket {throw new Exception;}', exception is still being thrown, empty does not work as expected.

Unset from array not looks working

Looks like unset not works properly or i am making something wrong:

public function has(var key)
{
    return isset this->keys[key];
}

public function set(var key, value)
{
    let this->keys[key] = true;
    let this->archive[key] = value;
}

public function remove(var key)
{
    if !this->has(key) {
        return;
    }

    unset this->archive[key];
    unset this->keys[key];
}   

var_dump($this->has('foo')); //return false
$this->set('foo','bar');
var_dump($this->has('foo')); //return true
$this->remove('foo');
var_dump($this->has('foo')); //return true

Syntax

Why has zephir a different syntax for things like foreach ?

It would make sense to be able to compile simple php files.

Magic constants

Can we use magic constants as DIR or METHOD with zephir, compiler return me an error when i use DIR

strtok CompilerException

strtok tokenizes a string and allows you to "iterate" through the given results. The first call to strtok requires both the string and a token. In order to iterate through the tokens, subsequent calls to strtok need to be made giving just the token.

Attempts to call strtok with just a single parameter result in:

CompilerException: The number of parameters passed is less than the number of requiered parameters by 'strtok'

Example code:

namespace Testing;

class Tokenizer
{
    public static function parse()
    {
        var first_token;
        var second_token;

        let first_token = strtok("/something", "/");
        let second_token = strtok("/");

        var_dump(first_token, second_token);
    }
}

Accessing MySQL Functions

Hello,

I would like to access mysql functions like accessing other php functions (strpos, strlen etc.).

How can I access?

namespace MySQLTest;

class TestingDB
{

    public function mysql_func(var id)
    {
    var result;
        mysql_connect("localhost", "root", "");
        mysql_select_db("cdcol");
        result = mysql_query("SELECT * cds WHERE id=" . id);
        // var row;

        // while (var row = mysql_fetch_assoc(result)){
        //  echo row["id"].' '.row["titel"];
        // }

        for key, value in mysql_fetch_assoc(result) {
            echo key.' '.value.'\n';
        }

    }
}

I got error like:

ParseException: Syntax error in /root/mysqltest/mysqltest/testingdb.zep on line 11

            result = mysql_query("SELECT * cds WHERE id=" . id);
    ---------------^

No Bitwise Operators

Currently Zephir doesn't understand PHP bitwise operators, i.e. |, &, etc. Bitwise or is particularly useful for constructing and evaluating flags.
Work around: Of course, strictly speaking, bitwise or is really the same as +.

Use typeof on Class Properties

A call like the following:

if typeof this->prop == "array" { ...

generates a compiler exception: "CompilerException: Typeof operator on non-variable"

Use of call_user_func/call_user_func_array function

Currently there is very difficult to implement __callStatic magic to functions with variable number of arguments because call_user_func/call_user_func_array functions has no access to protected/private methods of extension class.

Such code will compile OK, but runtime error will appear when we'll try to call own private or protected method with these functions.

Appending array with integer key generate //missing line but works with string key

Here is my code

class Example
{
    protected props;

    public function set(int idx, string name) -> void
    {
        if !isset this->props[idx] {
            let this->props[idx] = [];
        }

        var arr;
        let arr = this->props[idx];
        let arr[] = idx;
        let this->props[idx] = arr;
    }
}

It's produce some c code like this

PHP_METHOD(Test_Example, setHandler) {

    ...

    _0 = zephir_fetch_nproperty_this(this_ptr, SL("props"), PH_NOISY_CC);
    if (!(zephir_array_isset_long(_0, method))) {
        ZEPHIR_INIT_VAR(_1);
        array_init(_1);
        //missing
    }
    _2 = zephir_fetch_nproperty_this(this_ptr, SL("props"), PH_NOISY_CC);
    ZEPHIR_OBS_VAR(arr);
    zephir_array_fetch_long(&arr, _2, method, PH_NOISY TSRMLS_CC);
    zephir_array_update_zval(&arr, idx, &name, PH_COPY | PH_SEPARATE);
    //missing
    ZEPHIR_MM_RESTORE();

}

But no problem when use string as key.

Building with 5.5.3 causes a good lot of warnings - and errors.

Hey!

Compiling Zephir goes okay, but running ./bin/zephir gives me:

http://puu.sh/5Qfas.txt

Note, thats the 2nd run, so not everything may be contained.

Kind regards,
Ingwie

Missing require

require filePath; in .zep is converted to //missing require in .c

Allow PHP 5.3 use of new static()

I'd like to see support for late binding available in PHP 5.3 such as:

class A
{
  public static function makeNew()
  {
    return new static();
  }
}

class B extends A
{ }

$a = A::makeNew(); // $a is an A
$b = B::makeNew(); // $b is a B

Of course, this is only an over simplified example.

Constructor of classes extended from PHP Userland do not run.

This is an interesting little find (at least I think so)

I have a Zephir class: NOTICE; it's abstract with a final constructor

abstract class Test {
     public someValue;
     final public function __construct(){
          echo "This Ran";
          let this->someValue = "foobar";
     }
}

I have a PHP class:

class ChildTest extends \Ext\Test {
     public function whatever(){
     }
}

Now, here's the issue:

I have a method in my extension that takes a class name, creates an instance, and returns that instance (this is not what i'm actually doing, but this is what you can do to recreate the issue) NOTICE: I'm calling the class in a dynamic way.

class SomeKindOfLoader {
     // the method in a zephir class
     public function createInstance(className) 
     {
          return new {className}();
     }
}

now in php:

$somekindofloader = new \Ext\SomeKindOfLoader();
$ChildTest = $somekindofloader->createInstance('ChildTest');
var_dump($ChildTest);  // outputs object(ChildTest); however "This Ran" never shows up and $ChildTest->someValue is null

So... the constructor for \Ext\Test never runs. I DO however get an error if I try to override the final constructor from \Ext\Test.

Typeof produces a warning

Hi,

First all thanks for create this excellent language.

I am testing zephir and when i use typeof in this way:

 if typeof root == "object" {
...
}

produces a weird warning:

/Users/mcuadros/workspace/zephir/mongator/ext/mongator/zephirdocument.c:314:28: warning: equality comparison with extraneous parentheses [-Wparentheses-equality]
                        if ((Z_TYPE_P(embedded) == IS_OBJECT)) {
                             ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
/Users/mcuadros/workspace/zephir/mongator/ext/mongator/zephirdocument.c:314:28: note: remove extraneous parentheses around the comparison to silence this warning
                        if ((Z_TYPE_P(embedded) == IS_OBJECT)) {
                            ~                   ^           ~
/Users/mcuadros/workspace/zephir/mongator/ext/mongator/zephirdocument.c:314:28: note: use '=' to turn this equality comparison into an assignment
                        if ((Z_TYPE_P(embedded) == IS_OBJECT)) {

i know that is just a warning but can be interest fix it.

Regards!

new Dynamic Class Name variables passed as null.

Example: in the following each of these variables will be passed as null.

new {fullClassName}("variable one", "variable two", "variable three")

[NFR] Support for list()

It would be nice to can use list():

var width, height;
list(width, height) = getimagesize(value["tmp_name"]);

How to write this echo (5 & 1);

I got a ParseException: Syntax error. at here '&'

Break checking conditions if first not pass

I'm trying to use:

let value = 1;
if typeof value == "array" && isset value["error"] && value["error"] === 1 {
}

And I'm receiving:

Notice: Cannot use a scalar value as an array

Issue with type-hinted method parameters that have default values

Sorry I can't provide too much info, I've just observed this strange behavior:

I have a method defined as such:

class Thing {
     public function test(string! param1, string param2 = null)
     {
          var_dump(param1);
          var_dump(param2);
     }
}

This compiles just fine.

The issue comes when you attempt to call the method:

$thing->test('foo','bar');

This results in a php log entry:

 [17-Jan-2014 14:30:05.337043] WARNING: pid 768, fpm_children_bury(), line 252: [pool www] child 770 exited on signal 11 (SIGSEGV - core dumped) after 3.073586 seconds from start

The (userland) fix is to remove either the type or the default. Just thought I'd put this on your radar.

func_get_args

Could I call this function or get all args from method?

Multiline comments before class closing brace causes ParseException

Taking this as an example:

namespace Amnuts;

class Utils
{
    public function test() -> void
    {
        echo PHP_VERSION, PHP_EOL;
        /*
            This is OK
        */
        // as is this
    }

//
// This is OK
//

/*
    This produces parse error
*/
}

With the multiline comment at the end of the class it'll throw a ParseException due to a syntax error with the closing brace.

Output source codes brackets :D

router.c

if (((((((((ch >= 'a') && (ch <= 'z'))) || (((ch >= 'A') && (ch <= 'Z')))) || (((ch >= '0') && (ch <= '9')))) || (ch == '-')) || (ch == '_')) || (ch == ':'))) {

Work on this

@phalcon I would like to contribute project can your supervise me for next time like create task and milestones or etc mm?

Syntax error when use extends and implements

I encountered a problem that the parser generates an error when I extends from the other class and implements an interface

namespace Igor;

abstract class MyClassA
{
   // some methods here
}

namespace Igor;

interface MyInterfaceB
{
 // some methods here
}

namespace Igor;

abstract class MyClassC extends Igor\MyClassA implements Igor\MyInterfaceB
{
 // methods here
}

p.s. if in this class not use "abstract" then all works fine.

error:

ParseException: Syntax error in ....myclassc.zep

abstract class MyClassC extends Igor\MyClassA implements Igor\MyInterfaceB
-----------------------------------------------------^

can not support the dynamic class names

when I run ./bin/zephir compile in zephir directory

there is a warning:

Warning: Class "fullClassName" does not exist at compile time in zephir/test/oo/oodynamica.zep on 15 [nonexistent-class]

Missing implementation of the magic getters/setters

Shortcuts in Zephir aren't exported as real methods

class Event
{
    protected _type { set, get };

is compiled to:

PHP_METHOD(Phalcon_Events_Event, setType) {
        zval *type;
        zephir_fetch_params(0, 1, 0, &type);
}

PHP_METHOD(Phalcon_Events_Event, getType) {
}

but should be something like this:

PHP_METHOD(Phalcon_Events_Event, setType){
        zval *event_type;
        phalcon_fetch_params(0, 1, 0, &event_type);
        phalcon_update_property_this(this_ptr, SL("_type"), event_type TSRMLS_CC);
}

PHP_METHOD(Phalcon_Events_Event, getType){
        RETURN_MEMBER(this_ptr, "_type");
}

how to save value in static varibles ??

my zephir code is .......

// mage.zep
namespace magento;

final class Mage {
    static private _registry = null;

    public static function registry(key) {
        var __isset__;
        if fetch __isset__, self::_registry[key] {
            return self::_registry[key];
        }
        return null;
    }

    public static function register(key, value, graceful = false) -> void {
        if self::_registry === null { let self::_registry = []; }
        var __isset__;
        if fetch __isset__, self::_registry[key] {
            if (graceful){ return; }
            self::throwException("Mage registry key \"".key."\" already exists");
        }
        let self::_registry[key] = value; // this code is NOT woring...WHY?????
    }

    public static function throwException(message, messageStorage = null) {
        throw new Mage_Core_Exception(message);
    }
}

then build extension

zephir compile
cd ext
phpize && configure && make && make install 
echo "extension=magento.so" > /etc/php.d/magento.ini
service httpd restart

then My PHP Code for test is.......

<?php
use \Magento\Mage as Mage;
Mage::register("myid", "4535363");
var_dump( Mage::registry("myid") );
?>

the webpage result is .........

null

It is not working the zephir code below. not saved...
self::_registry[key] = value;

why is not saved static variables ?

Array_keys causes a memory leak

I'm trying to use array_keys:

let byteUnits = ["B": 0, "K": 10, "M": 20, "G": 30, "T": 40, "KB": 10, "MB": 20, "GB": 30, "TB": 40];
let tmp = implode("|", array_keys(byteUnits));

and I have memory leak:

Fatal error:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 32 bytes) in /home/mruz/Dropbox/osc/test/app/frontend/controllers/IndexController.php on line 40

Exceptions handling

I couldn't find the way how to handle exceptions.
Will the Zephir support something like "try {} catch ()"?
