New in Symfony 6.1: Profiler Improvements (part 1)

In Symfony 6.1 we've added lots of new features to the Symfony Profiler. We already highlighted the new Serializer profiler panel in a previous blog post. In this two-part series we're going to highlight the other new profiler features.

Checking if Profiler is Enabled

        Contributed by Bilge
         in #45265.

The Symfony Profiler can be disabled entirely or programmatically to adapt it to your needs. If it's disabled, you might still have services that collect information for it, even if that information will be later discarded. That's why in Symfony 6.1 we've added a new isEnabled() method to the main profiler object. Use that method to check if you should collect information or if you should instead skip that collection to improve performance.

Displaying Inherited Security Roles

        Contributed by Jonathan Scheiber
         in #44284.

Symfony security allows you to define hierarchical roles. That's why users in your application usually have more roles than the ones granted explicitly to them. In Symfony 6.1 we're improving the debug toolbar to display inherited roles in addition to the regular roles:

Better Email Debugging

        Contributed by Thomas Lallement
         in #45765.

In dev environment it's common to send all emails to the same address, regardless of their original address, to ease their debugging. In Symfony 6.1 we've improved the profiler to display both the to email address and the recipient, if it exists (it's taken from the envelope of the message):

        Contributed by Daniël Brekelmans
         in #44917.

If some email message includes file attachments, the profiler lists the name of those files. In Symfony 6.1 we've improved this feature so you can also download the file attachments. This will help you debug many issues related to the generation of those files.
