Xdebug 3.0.0

Hi, when is the included xdebug 2.9.0 going to be updated to the recently released 3.0.0 (Nov. 25, 2020)? Version 3 offers several significant performance improvements to the debugging experience.

Just wanted to let you know that PhpStorm 2020.3 does not work with Xdebug < v2.9.6, see https://youtrack.jetbrains.com/issue/WI-57282.
While this issue will be fixed in 2020.3.1, Local should definitely update Xdebug, at least to the latest v2.* version, which is v2.9.8 as of time of writing, see https://xdebug.org/announcements/2020-09-28.

xDebug is now at 3.0.1 and Local Beta is testing PHP 8 with xDebug 3.0. It’s probably time to consider updating the other PHP lightning services to use xDebug 3.x. This should now be more painless with the lightning services updater

Working default settings for xDebug 3.x and Local can be found here, Install PHP 8

It would require updates to have xDebug 3.x listening on port 9003 for any add-ons that set these values.

I don’t have an eta on when this will be worked on, but I have put it on our development radar!

I’m not sure what the difficulty is in updating the default configuration in LocalWP but I was able to determine a workaround based on how I observed the settings changed when moving between PHP 7 and 8 for my site in LocalWP.

Here’s my workaround to backport xdebug 3 to PHP 7.4:

1. Download the latest php_xdebug DLL that matches the PHP version running for the site in LocalWP from Xdebug: Downloads
   In my case on a Windows OS it was to download this one PHP 7.4 VC15 (64 bit)
2. Copy that DLL into the Local lightning-services folder for the respective PHP version (e.g. %APPDATA%\Local\lightning-services\php-7.4.1+14\bin\win64\ext
3. For simplicity, I renamed the downloaded DLL to php_xdebug3.dll
4. Edit the LocalWP site’s php.ini.hbs config file’s [xdebug] section with the following (I kept the old xdebug settings in {{!-- --}} comment blocks just in case I want to go back to the built-in xdebug v2:

{{!--
[xdebug]
{{#if os.windows}}
zend_extension = php_xdebug.dll
{{else}}
zend_extension = {{extensionsDir}}/xdebug.so
{{/if}}

xdebug.remote_enable=1
xdebug.remote_connect_back=Off
xdebug.remote_port="9000"
xdebug.profiler_enable=0
--}}

[xdebug]
{{#if os.windows}}
zend_extension = php_xdebug3.dll
{{else}}
zend_extension = {{extensionsDir}}/xdebug.so
{{/if}}

xdebug.mode=debug
xdebug.client_port="9000"
xdebug.start_with_request=yes
xdebug.discover_client_host=yes

5. Restart your LocalWP site and confirm the upgrade by visiting your PHP info page (/local-phpinfo.php):

Great!
It is working,just the location of the file is:

%APPDATA%\Roaming\Local\lightning-services\php-7.4.1+14\bin\win64\ext

Thank you!
