Contribution Detail Report - DOMPDF Failure - render() -
March 01, 2013, 07:58:59 am
Module failing: \htdocs\drupal\sites\all\modules\civicrm\CRM\Utils\PDF\Utils.php

Code starting at line 108:

-------------------------------------------------

  static function _html2pdf_dompdf($paper_size, $orientation, $html, $output, $fileName) {
    require_once 'packages/dompdf/dompdf_config.inc.php';
    spl_autoload_register('DOMPDF_autoload');
    $dompdf = new DOMPDF();
    $dompdf->set_paper($paper_size, $orientation);
    $dompdf->load_html($html);
   
//Debug   

echo $html; exit;

ini_set('memory_limit', '-1');
ini_set('max_execution_time', 0);
ini_set('max_input_time', 0);

$dompdf->render();

echo 'Here 400!!'; echo $html; exit;

-----------------------------------------------------

With the exit in place, the report shows up on the screen as expected.

When I remove the exit statement, the code fails in the render() code ... ie, I never see the output from echo 'Here 400!!'

Help would be appreciated

dompdf most likely is running out of memory int the render function due to the large size of the html

you might want to try using wkhtmltopdf which is a lot more scalable, faster and memory efficient (its also a binary rather than php)

Can you point me in the direction concerning how to make this configuration change?
I don't mind researching it, just if I can get in the right direction ...
Thanks,
Roy

Thanks for the help.
I thought I'd pass along this last obstacle I encountered ... since I'm not familiar with the development/issues tracking/etc. platforms, I thought I'd share it here ...

In this modeule: //Hqinternal01\e$\Apache24\htdocs\drupal\sites\all\modules\civicrm\packages\snappy\src\Knp\Snappy\AbstractGenerator.php
   
 protected function executeCommand($command)
    {   
        $stdout = $stderr = $status = null;
        $descriptorspec = array(
           1 => array('pipe', 'w'),  // stdout is a pipe that the child will write to
           2 => array('pipe', 'a') // stderr is a pipe that the child will write to     //<----------------- Line 391 changed from 'w' to 'a'
        );

was hanging in the stream_get_contents code just below this.

Yes, it appears there is a newer version of the Snappy code on Github.  It doesn't use the pipe method.

I have another question if you don't mind - it's the same report I you helped me with earlier. The PDF version is working well. I'm grateful for you help on that.

When I do the print function, the complete report only prints if I chose legal sized paper, portrait mode with 70% fit to page. Other settings cause it to print, but anywhere from 1/2 to 2/3 of the rows don't end up in the printed report.

I commented out the window.print dialog initiator in the .tpl - so I could view the page source - doesn't have any css reference (@import, <style>, or <link> statements related to css).

On the wkhtmltopdf generated output, it looks perfect.

Any ideas?

Thanks,
Roy

can you take a look and update your local site and if it does work, please create an issue and file a patch with the changes to the newer version. Or you can send us a pull request with a jira created issue number

r u talking about this page:

http://sandbox.drupal.civicrm.org/civicrm/report/instance/21?snippet=2 (u'll need to login)

If i do a view source, i do see an import of print.css

thanx
