Publish extension assets during installation

[Guite]

When an extension is installed, it's assets should be copied into the appropriate subfolder of web.

And when an extension is upgraded? Removed when uninstalled?

[Guite]

Yes.

This needs to be done for modules as well as themes.

the difficulty here is that the web user (php?) may not have rights to the /web directory. The assets are typically installed by composer being run at the CLI by a user with rights to the directory. The php user typically has rights only to the cache directory.

If the rights issue is worked out, then this is pretty straightforward, I think.

core/src/lib/Zikula/Bundle/CoreBundle/Command/AssetsInstallCommand.php

Line 68 in 1eb9e37

protected function execute(InputInterface $input, OutputInterface $output)

Modules should also be able to perform custom push/copy operations. For example if images are dynamically generated they need to be copied into the web folder again after they have been updated.

again - I don't see how this can be done as there will be a rights/access issue to the /web directory

[Guite]

possible if we depend that on #3438 ;-)

[craigh]

actually, this was originally implemented

core/src/system/ExtensionsModule/Controller/ModuleController.php

Line 350 in 68f862e

// $this->get('zikula_extensions_module.extension_helper')->installAssets();

but it is commented because the feature takes too long.

refs #3804

[Guite]

Moved to 3.0.0 because index.php will be moved into public folder!

[craigh]

FYI - this is now done 'on demand' when the asset is needed and not found, it is copied from the bundle public directory to the project public directory and served from there. This could be sped up further (maybe) by

1. symlink instead of full copy
2. do not check files for existence (and similar later in class)

[Guite]

Proposal for a first solution of this task:

An event handler should remove all assets from public/modules/acmefoomodule/ when AcmeFooModule is updated (to ensure renewal) or removed (to cleanup).
