Upgrade to Nextcloud 20

Note

Critical changes were collected on GitHub. See the original ticket for links to the pull requests and tickets.

Front-end changes

Body theme

The body theme classes are now theme--highcontrast, theme--dark and/or theme--light.

jQuery update

jQuery was updated to v2.2. The most notable change is that $(document).ready(...) or $(...) for short fires sooner than before. Use the DOMContentLoaded event instead.

Search

The unified search replaces the traditional search input, hence OCA.Search became a noop. For backwards compatibility, the code will not raise any errors now, but it does not have any functionality.

Removed globals

• escape-html: use the escape-html package <https://www.npmjs.com/package/escape-html> or similar

Deprecated global variables

• humanFileSize: use formatfilesize from https://www.npmjs.com/package/@nextcloud/files

• OC.getCanonicalLocale: use getCanonicalLocale from https://www.npmjs.com/package/@nextcloud/l10n

Removed jQuery plugins

• $.tipsy

Back-end changes

App bootstrap logic

The code that initializes an app or anything that should run for every request and command is now moved to a dedicated and typed API. The appinfo/app.php is therefore obsolete and deprecated. See bootstrapping for details.

PSR-3 integration

Nextcloud 20 is the first major release of Nextcloud that brings full compatibility with PSR-3: Logger Interface. From this point on it is highly recommended to use this interface mainly as the old \OCP\ILogger got deprecated with the last remaining changes. The majority of methods are identical between the Nextcloud-specific interface and the PSR one. Pay attention to usages of \OCP\ILogger::logException as that method does not exist on the PSR logger. However, you can specifcy an exception key in the $context argument of any \Psr\Log\LoggerInterface method and Nextcloud will format it like it did with the old logException.

PSR-11 integration

Nextcloud 20 is the first major release of Nextcloud that brings full compatibility with PSR-11: Container Interface. From this point on it is highly recommended to use this interface mainly as the old \OCP\IContainer got deprecated with this change.

The interfaces \OCP\AppFramework\IAppContainer and \OCP\IServerContainer will remain, but they won’t extend the IContainer anymore once that interface gets removed. As a result, IAppContainer and IServerContainer will eventually become tagging interfaces with the sole purpose of making it possible to have either the app or server container injected explicitly.

If your app requires Nextcloud 20 or later, you can replace any of the old type hints with one of \Psr\Container\ContainerInterface and replace calls of query with get, e.g. on the closures used when registering services:

// old
$container->registerService('DecryptAll', function (IAppContainer $c) {
  return new DecryptAll(
    $c->query('Util'),
    $c->query(KeyManager::class),
    $c->query('Crypt'),
    $c->query(ISession::class)
  )
})

becomes

// new
$container->registerService('DecryptAll', function (ContainerInterface $c) {
  return new DecryptAll(
    $c->get('Util'),
    $c->get(KeyManager::class),
    $c->get('Crypt'),
    $c->get(ISession::class)
  )
})

Note

For a smoother transition, the old interfaces were changed so they are based on ContainerInterface, hence you can use has and get on IContainer and sub types.
