Question: How much ignored messages should be within a regular expression until the performance gets down?

Hi,

due to the fact that many exceptions are coming from 3rd party extension it's not that easy to fix all of them.

Is there a max number of messages which you put in the regular expression as a maximum value?

I bet preg_match() has a limit, never checked.

It could be cleaner to have a list of regular expressions (that needs to go to EXTCONF)

EXTCONF:
  sentry_client:
    ignoreMessageRegexp:
      # Bots on Powermail forms
      - 'Required argument.*mail.*Powermail.*FormController.*create'
      # Forbidden backend access (https://review.typo3.org/c/Packages/TYPO3.CMS/+/84726)
      - 'The IP address of your client does not match the list of allowed IP addresses'

What do you think?

That looks very clean to me. However, do I understand correct: each array item represents an regex? With that approach it's also easily possible to add some regexps for exact matching and not exact matching which is pretty useful!
