$compiler->compileString() returns FALSE instead of a string #2198

dedalozzo · 2014-03-18T19:40:38Z

This code used to work in the past, but I have tried to downgrade with no success. After many tests I figured out that any calls to compileString() returns FALSE:

$volt = new \Phalcon\Mvc\View\Engine\Volt($this->view, $this->di);
$compiler = $volt->getCompiler();
$compiler->addFilter('ucwords', 'ucwords');
var_dump($compiler->compileString('{{ "hello"|ucwords }}'));

should return:

// string '<?php echo ucwords('hello'); ?>' (length=31)

instead it returns:

// false

Since the compileString() returns FALSE, I'm not able to get a valid response, unless I don't use a custom filter. In case of a custom filter in fact I get a "no data received" Chrome blank page.

This is the service:

<?php

use Phalcon\Mvc\View\Engine\Volt;

// Creates an instance of Volt template engine and return it.
$di->setShared('volt',
  function($view, $di) use ($root, $config) {
    $volt = new Volt($view, $di);

    $volt->setOptions(
      [
        'compiledPath' => $root.$config->application->cacheDir.'volt/',
        'compiledExtension' => '.compiled',
        'compiledSeparator' => '_',
        'compileAlways' => TRUE
      ]
    );

    $compiler = $volt->getCompiler();

    $compiler->addFilter('minustospace',
      function($resolvedArgs, $exprArgs) {
        return "str_replace('-', ' ', '".$resolvedArgs."')";
      }
    );

    return $volt;
  }
);

This instead is the template when I'm using the filter:

{% if subsectionMenu is defined  %}
<ul class="list pills small">
  {% for i, item in subsectionMenu %}
    <li{{ (i == subsectionIndex) ? ' class="active pull-right"' : ' class="pull-right"' }}><a href="{{ controllerPath~actionPath~item }}">{{ item|minustospace|upper }}</a></li>
  {% endfor %}
</ul>
{% endif %}

I can only use a built-in filter, because any custom filter produces the issue described.

1.2.6 only had a change in Phalcon\Security, there's no way it could affect Volt

dedalozzo · 2014-03-18T20:01:28Z

Using git I see that my last commit to the volt.php file is dated June 9, 2013 with the message: "added the 'minustospace' filter, that replaces minus with spaces".
Maybe something related to 1.2.5? I can try to downgrade Phalcon to see what happens.

dedalozzo · 2014-03-19T21:04:01Z

Tried to downgrade and nothing changed. Probably is something I have changed but I can't figure out what. If I remove the following statement

  $compiler->addFilter('minustospace',
    function($resolvedArgs, $exprArgs) {
      return "str_replace('-', ' ', '".$resolvedArgs."')";
    }
  );

I get an exception because the program can't find the filter, else I get a "No data received" in Chrome and the page is not displayed. Any idea? I can't even debug because the template is not generated when the filter is added. At this point I don't think it's a Phalcon bug, but any hint can be useful to find a solution.

dedalozzo · 2014-03-21T16:14:32Z

OK, dunno what happens here, but this code returns FALSE:

$volt = new \Phalcon\Mvc\View\Engine\Volt($this->view, $this->di);
$compiler = $volt->getCompiler();
$compiler->addFilter('ucwords', 'ucwords');
var_dump($compiler->compileString('{{ "hello"|ucwords }}'));

should return:

// string '<?php echo ucwords('hello'); ?>' (length=31)

instead it returns:

// false

So it's definitely a bug. Please try it and let me know how can I help you.

phalcon · 2014-03-23T22:51:45Z

Executing this test:

<?php

$di = new Phalcon\DI\FactoryDefault();

$di['view'] = function(){
    return new Phalcon\Mvc\View();
};

$volt = new \Phalcon\Mvc\View\Engine\Volt($di['view'], $di);
$compiler = $volt->getCompiler();
$compiler->addFilter('ucwords', 'ucwords');
var_dump($compiler->compileString('{{ "hello"|ucwords }}'));

It outputs:

string(31) "<?php echo ucwords('hello'); ?>"

Could you please update my test to demonstrate the bug?

dedalozzo · 2014-03-27T18:40:24Z

When a closure is provided the filter doesn't work. See the code below:

$volt = new \Phalcon\Mvc\View\Engine\Volt($di['view'], $di);

$compiler = $volt->getCompiler();

$compiler->addFilter('minustospace',
  function($resolvedArgs, $exprArgs) {
    return "str_replace('-', ' ', '".$resolvedArgs."')";
  }
);

$compiler->addFilter('ucwords', 'ucwords');

$compiler->addFilter('likeucwords',
  function($resolvedArgs, $exprArgs) {
    return "ucwords('".$resolvedArgs."')";
  }
);

var_dump($compiler->compileString('{{ "it-works"|ucwords }}')); // Works.
var_dump($compiler->compileString('{{ "it-works"|upper }}')); // Works.
var_dump($compiler->compileString('{{ "it-does-not-work"|likeucwords }}')); // Doesn't work.
var_dump($compiler->compileString('{{ "it-does-not-work"|minustospace }}')); // Doesn't work.

maxgalbu · 2014-04-02T07:26:12Z

I have just tested it under php 5.5 and it works. Are you on windows? see #2269

dedalozzo · 2014-04-02T12:37:16Z

I'm on Mac OS X version 10.7.5 with PHP 5.5.10. Did you try on Linux?

maxgalbu · 2014-04-02T13:52:22Z

Yes I did, CentOS with php 5.5.9 from CLI. Did you try from cli? Just put the test code in a file and then run

php -f [your_filename].php

Here's my full test file:

<?

$di = new Phalcon\DI\FactoryDefault();

$di['view'] = function(){
    return new Phalcon\Mvc\View();
};

$volt = new \Phalcon\Mvc\View\Engine\Volt($di['view'], $di);

$compiler = $volt->getCompiler();

$compiler->addFilter('minustospace',
  function($resolvedArgs, $exprArgs) {
    return "str_replace('-', ' ', '".$resolvedArgs."')";
  }
);

$compiler->addFilter('ucwords', 'ucwords');

$compiler->addFilter('likeucwords',
  function($resolvedArgs, $exprArgs) {
    return "ucwords('".$resolvedArgs."')";
  }
);

var_dump($compiler->compileString('{{ "it-works"|ucwords }}')); // Works.
var_dump($compiler->compileString('{{ "it-works"|upper }}')); // Works.
var_dump($compiler->compileString('{{ "it-does-not-work"|likeucwords }}')); // Doesn't work.
var_dump($compiler->compileString('{{ "it-does-not-work"|minustospace }}')); // Doesn't work.
?>

I'm getting

string(34) "<?php echo ucwords('it-works'); ?>"
string(46) "<?php echo Phalcon\Text::upper('it-works'); ?>"
string(44) "<?php echo ucwords(''it-does-not-work''); ?>"
string(58) "<?php echo str_replace('-', ' ', ''it-does-not-work''); ?>"

maxgalbu · 2014-04-02T13:59:34Z

Wait LOL I think i saw the problem, there's double quotes around the string when the closure is used, how did I not see that?

Let me try with php 5.3.

dedalozzo · 2014-04-02T14:05:28Z

php -f lippo.php

string(34) ""
string(46) ""
Segmentation fault: 11

dedalozzo · 2014-04-02T14:09:15Z

This is the lippo.phpcontent:

<?php

use Phalcon\DI\FactoryDefault as DependencyInjector;
use Phalcon\Mvc\Application as Application;

$loader = new \Phalcon\Loader();
$loader->register();

$di = new DependencyInjector();

$di['view'] = function(){
    return new Phalcon\Mvc\View();
};

$volt = new \Phalcon\Mvc\View\Engine\Volt($di['view'], $di);
$compiler = $volt->getCompiler();

$compiler->addFilter('minustospace',
  function($resolvedArgs, $exprArgs) {
    return "str_replace('-', ' ', '".$resolvedArgs."')";
  }
);

$compiler->addFilter('ucwords', 'ucwords');

$compiler->addFilter('likeucwords',
  function($resolvedArgs, $exprArgs) {
    return "ucwords(".$resolvedArgs.")";
  }
);

var_dump($compiler->compileString('{{ "it-works"|ucwords }}'));
var_dump($compiler->compileString('{{ "it-works"|upper }}'));
var_dump($compiler->compileString('{{ "it-does-not-work"|likeucwords }}'));
var_dump($compiler->compileString('{{ "it-does-not-work"|minustospace }}'));

It's a segmentation fault, something related memory allocation I think.

maxgalbu · 2014-04-02T14:34:16Z

Tested under MacOSX 10.8.5 and php 5.3 (default installed), no segmentation fault. Can you rebuild phalcon in debug mode and then run it under gdb? See these instructions:

cd cphalcon/ext

#reinstall phalcon in debug mode
sudo ./install

#run gdb with php cli
gdb --args /usr/bin/php -f testvolt.php

#when you see gdb cli, input:
run

#when it segfaults, input:
bt

#and then paste your input here

Sorry, i forgot the --args parameter:

Same result, except for the starting program now is /usr/bin/php -f lippo.php

OK, it's an issue related to xdebug. I disabled it and the everything works:

string(34) "<?php echo ucwords('it-works'); ?>"
string(46) "<?php echo Phalcon\Text::upper('it-works'); ?>"
string(42) "<?php echo ucwords('it-does-not-work'); ?>"
string(56) "<?php echo str_replace('-', ' ', 'it-does-not-work'); ?>"

Program exited normally.

Now I'm asking, why this happen? It's a Phalcon bug or an xdebug issue? It seems that xdebug is trying to read a memory location that can't be read.

maxgalbu · 2014-04-03T08:30:32Z

It could be a phalcon stack trace that xdebug is trying to inspect or some leak from phalcon that affect xdebug. I had some issues too with xdebug, disabled it and had no issue since that.

Also, see #2239.

Added a pull request on xdebug to fix the problem: xdebug/xdebug#120
