Xdebug 3 research

Support

Xdebug hooks into PHP's internals deeply in order to offer it's fetures of step debugging, tracing, profiling and others. So each PHP version has a matching Xdebug version.

The latest version of Xdebug, Xdebug 3, only supports PHP versions back to 7.2. However, that's a longer support period than even PHP itself provides.

See the compatibility table for more info: https://xdebug.org/docs/compat#supported-versions

Magento Debugging Cheatsheet: Cron Edition

• Verify the cron is installed properly in the crontab. Run php bin/magento cron:install to install the cron.
• Verify it is installed for the web server user. Use crontab -l to list the crontab for the current user.
  • The command Magento runs is: /usr/bin/php /var/www/vhosts/magento-project/html/bin/magento cron:run 2>&1 | grep -v "Ran jobs by schedule" >> /var/www/vhosts/magento-project/html/var/log/magento.cron.log
• Verify that the line in crontab is not commented out (i.e. Does not start with #).
• Verify the cron is running properly. Run php bin/magento cron:run to run the cron. This prompts Magento to generate new cron schedules in the cron_schedule table.
• Verify other cron jobs are running
