Weasyprint Process Timeout

[Daniel-FDS]

Good day

I have a Codeigniter PHP web app that implements php-weasyprint. I sometimes (5% of the time) get the following error when a user generates a document:

The process "/usr/local/bin/weasyprint '/tmp/php_weasyprint6489782e31d4e8.37601559.html' '.../d9cb68c13f6489782e30fcf.pdf'" exceeded the timeout of 10 seconds.

I cannot seem to see why this happens. It is also interesting, because when the error appears, it is almost immediately after the quotation generation has been initiated, not 10 seconds later.

Is there any reason why this could be happening? I am not sure what code to share, but at least this is my document generator function:

`

          class Document_Generator
          {
              function create_pdf(
                  $html,
                  $complete_relative_path
              ) {

                  $pdf = new Pdf('/usr/local/bin/weasyprint');
                  if (file_exists($complete_relative_path)) {
                      unlink($complete_relative_path);
                  }
                  return $pdf->generateFromHtml($html, $complete_relative_path);
              }
          }

Hi @Daniel-FDS , the timeout of WeasyPrint command is managed by Symfony Process component, it should just work. To increase the timeout you can set its value using the setTimeout method:

$pdf = new Pdf('/usr/local/bin/weasyprint');
$pdf->setTimeout(60); //set timeout to one minute

To further debug your issue you can attach a Psr\Log\LoggerInterface compatible logger (like Monolog) with setLogger() method:

use MonologLogger;
use MonologHandlerStreamHandler;

$logger = new Logger('logger');
$logger->pushHandler(new StreamHandler(__DIR__ . '/weasyprint.log', Logger::DEBUG));

$pdf = new Pdf('/usr/local/bin/weasyprint');
$pdf->setTimeout(60); //set timeout to one minute
$pdf->setLogger($logger);

Hi Manuel

Thank you so much for your reply, I appreciate it. Both the timeout increase and the logging will be very helpful in this case. I will try and report if anything noteworthy arises hereafter.

Thank you once again 🙏🏼
