Given this as a PR to @nikosdion https://github.com/akeeba/angie/pull/76 so we can try and get an official version of the restore.php code with this in. Rather than starting to monkey patch this ourselves. If we do need to patch this way we'll need to modify the copyright at the top of restore.php similar to how we did in fof with 4889f00

[SharkyKZ]

Should we make changes to FoF too? And what about other libraries like idna_convert and lessphp?

Never change an upstream library. If needed submit a pull request to that libraries vendor

[SharkyKZ]

Those libraries aren't maintained. We did make changes to FoF in the past https://github.com/joomla/joomla-cms/commits/staging/libraries/fof.

[wilsonge]

FOF is fine to change. idna convert is also fine as it's something internal to string and doesn't exist on packagist. i already did that one in the framework joomla-framework/string@33944ac

Let's try submitting lessphp back to them - leafo/lessphp@v0.5.0...master but there hasn't been a release in nearly 5 years - so unsure whether they'll actually accept it or not.

[SharkyKZ]

Submitted leafo/lessphp#647.

[nikosdion]

Hey, guys. Thank you for the PR! George made it to the wrong repo but don't worry, I know where else to apply it :)

@wilsonge Do you want me to make a PR with the new version of restore.php? If so, only J3 or both J3 and J4?

[wilsonge]

Thankyou very much! Sorry for the wrong repo thing. Just to j3 please and it will get merged upto j4

[wilsonge]

@SharkyKZ can you remove the restore.php changes from this PR please and they'll be covered in @nikosdion 's separate PR

[SharkyKZ]

Done.

[nikosdion]

I PR'ed the new restore.php, see #25793

BTW, has anyone managed to reliably run PHP 7.4 betas on either macOS or Ubuntu 19.04? I don't want to have to pull in half of the known universe to compile it myself on Ubuntu, I really don't have the time anymore :/

[wilsonge]

I haven't yet - but we're doing it in drone with the php 7.4 nightly docker container - so i think that's where i'm going to start at https://github.com/joomla/joomla-cms/blob/4.0-dev/.drone.yml#L73

[nikosdion]

@wilsonge OK, that's pretty much what I thought I would have to do. I am not a huge fan of dockerizing everything because of various issues I've had with XDebug, hostnames, testing CLI applications and ownership / permissions of files in mounted volumes but I digress. I am now using https://github.com/devilbox/docker-php-fpm-7.4 because it solves the ownership / permissions issue and creates a tidy PHP-FPM server I can use with my localhost setup, e.g.:

docker run \
	--rm -d --name devilbox-php74 \
	-e NEW_UID=$(id -u) \
	-e NEW_GID=$(id -g) \
	-e TIMEZONE="Europe/Athens" \
	-e DOCKER_LOGS=0 \
	-e FORWARD_PORTS_TO_LOCALHOST="3306:host.docker.internal:3306, 1025:host.docker.internal:1025, 6379:host.docker.internal:6379" \
	-p 127.0.0.1:9074:9000 \
	-v $(pwd)/logs:/var/log/php \
	-v $(pwd)/php_config:/etc/php-custom.d \
	-v /path/to/my/sites:/path/to/my/sites \
	-v /path/to/my/git/repos:/path/to/my/git/repos \
	-t devilbox/php-fpm:7.4-work

to start the PHP-FPM server and then a couple of lines in my .htaccess to use it:

<FilesMatch "\.php$">
SetHandler "proxy:fcgi://127.0.0.1:9074/"
</FilesMatch>

R.E the lessphp library, it looks like one of the forks has a lot of PR ported from the original repo and has more interaction: https://github.com/MarcusSchwarz/lesserphp

May be an idea to submit your PR there

[SharkyKZ]

@C-Lodder I don't think that library is compatible with ours.

Files in libraries/idna_convert need a notification they have been altered.

[SharkyKZ]

@mbabker Added note. Thanks.

[HLeithner]

Thanks for fixing deprecated the syntax.
