FileValidationEvent may not report the correct file size

o'briat → made their first commit to this issue’s fork.

Don't know if it's revelant, but file_validate_image_resolution was removed without replacement, see https://www.drupal.org/node/3363745 → & https://www.drupal.org/project/drupal/issues/3221793 📌 Move file upload validation from file.module to constraint validators Fixed

Don't think it is relavant, as ClamAV only uses/used hook_file_validate where the file size passed is incorrect if the file is resized

I push the same patch to the new constraint part:
Works for me.
kerneltest is ok.

There's another usage of $image->save() in "navigation" experimental module core/modules/navigation/src/Form/SettingsForm.php:286.

But the resize is done after the validation.

opened the MR but putting into NW because the summary is incomplete, please keep the full template and fill in relevant sections

Updated issue to use full template and filled out to best of my knowledge

Update description and put back the issue to needs review.
The "PHPUnit Build" pipeline task failed, but it doesn't seem to be related to this issue.

I confirm the merge request fixes the issue with ClamAV not working with resized images.

The MR also applied cleanly to 10.5.x

Tests are failing and comments in #9 need to be addressed. See https://www.drupal.org/docs/develop/issues/fields-and-other-parts-of-an-... → for details on what makes an issue RTBC.

Re-ran the tests and they are back to green.

I do believe as per rules you linked it was RTBC, also as per o'briat judgement of why tests were failing, but I will not leave to someone else to RTBC this issue/MR :)

@kim.pepper
To me #9 was with #12.

Since the tests are now OK, I put back the issue as "Needs review".

As per my comment #15, RTBC from my side

I think this is ready to go.

Committed and pushed 29704ed8d21 to 11.x and 74feffe03e3 to 11.2.x and d60071fb257 to 10.6.x and cbd00a5f38a to 10.5.x. Thanks!
