Hi David, many thanks for the quick and good work. We installed and tested the example plugin and it absolutely does the job!!! Just one thing: When we hit “duplicate”, the duplication takes place, but the resulting page shows no content, as if it has not worked correctly. However, checking again the available media confirms that the duplication has taken place (I also checked the actual creation of the various files with different dimension – they are always created as they should).

Many many thanks! I just sent a 100 USD donation to your ALS charity – you are doing such great work there. All the best to you and Ilana!

Thanks for looking into this! I agree that a separate example plugin may be the best solution for our case. We look forward to hearing from you how it could work.

Now, I also took a look at the WP core code. It seems that new opcache-related code was introduced 2 weeks ago. They do not reset the whole opcache but rather use PHP’s opcache_invalidate function to selectively invalidate the opcache for individual files that have changed.

Without such a mechanism auto-updates would be too risky to implement. But to me it looks like the new functionality works also on standard updates.

Thanks for the quick answer, @satollo !

@alignak Thank you so much!

It took a little reading/trying to find out, where to put the remove_action. But now it works as intended! Great!

Maybe someone else will need this info too: I put this in the functions.php of my child theme to prevent html minification on the page with the stub “email-newsletter”.

add_action('template_redirect', 'remove_htmlmin_in_newsletter');

function remove_htmlmin_in_newsletter() {
    if(is_page('email-newsletter')){
        remove_action('template_redirect', 'fastvelocity_min_html_compression_start', PHP_INT_MAX);
    }
}

Thanks – I really should have read your blog!!!

I absolutely agree that there is no silver bullet and that each setup needs testing to see what works best in the particular situation.

But we are just dipping our feet in HTTP/2 and thus we start playing it by the book (which, of course, says: no concatenation anymore).

Looking forward to the new feature! Good luck and thanks again for your great work!
