Bug introduced by
It seems like you code against a concrete implementation and not the interface OC\Hooks\Emitter as the method emit() does only exist in the following implementations of said interface: OCA\Files_Sharing\Scanner, OC\App\CodeChecker\CodeChecker, OC\App\CodeChecker\InfoChecker, OC\Files\Cache\Scanner, OC\Files\Config\MountProviderCollection, OC\Files\Node\LazyRoot, OC\Files\Node\Root, OC\Files\ObjectStore\NoopScanner, OC\Files\Utils\Scanner, OC\Group\Manager, OC\Hooks\BasicEmitter, OC\Hooks\ForwardingEmitter, OC\Hooks\LegacyEmitter, OC\Hooks\PublicEmitter, OC\SubAdmin, OC\Updater, OC\User\Manager.

Let’s take a look at an example:

interface User
{
    /** @return string */
    public function getPassword();
}

class MyUser implements User
{
    public function getPassword()
    {
        // return something
    }

    public function getDisplayName()
    {
        // return some name.
    }
}

class AuthSystem
{
    public function authenticate(User $user)
    {
        $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
        // do something.
    }
}

In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break.

Available Fixes

  1. Change the type-hint for the parameter:

    class AuthSystem
    {
        public function authenticate(MyUser $user) { /* ... */ }
    }
    
  2. Add an additional type-check:

    class AuthSystem
    {
        public function authenticate(User $user)
        {
            if ($user instanceof MyUser) {
                $this->logger->info(/** ... */);
            }
    
            // or alternatively
            if ( ! $user instanceof MyUser) {
                throw new \LogicException(
                    '$user must be an instance of MyUser, '
                   .'other instances are not supported.'
                );
            }
    
        }
    }
    
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.

Documentation introduced by
$quota is of type false|double, but the function expects a integer.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

Bug introduced by
It seems like you code against a concrete implementation and not the interface OC\Hooks\Emitter as the method emit() does only exist in the following implementations of said interface: OCA\Files_Sharing\Scanner, OC\App\CodeChecker\CodeChecker, OC\App\CodeChecker\InfoChecker, OC\Files\Cache\Scanner, OC\Files\Config\MountProviderCollection, OC\Files\Node\LazyRoot, OC\Files\Node\Root, OC\Files\ObjectStore\NoopScanner, OC\Files\Utils\Scanner, OC\Group\Manager, OC\Hooks\BasicEmitter, OC\Hooks\ForwardingEmitter, OC\Hooks\LegacyEmitter, OC\Hooks\PublicEmitter, OC\SubAdmin, OC\Updater, OC\User\Manager.

Let’s take a look at an example:

interface User
{
    /** @return string */
    public function getPassword();
}

class MyUser implements User
{
    public function getPassword()
    {
        // return something
    }

    public function getDisplayName()
    {
        // return some name.
    }
}

class AuthSystem
{
    public function authenticate(User $user)
    {
        $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
        // do something.
    }
}

In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break.

Available Fixes

  1. Change the type-hint for the parameter:

    class AuthSystem
    {
        public function authenticate(MyUser $user) { /* ... */ }
    }
    
  2. Add an additional type-check:

    class AuthSystem
    {
        public function authenticate(User $user)
        {
            if ($user instanceof MyUser) {
                $this->logger->info(/** ... */);
            }
    
            // or alternatively
            if ( ! $user instanceof MyUser) {
                throw new \LogicException(
                    '$user must be an instance of MyUser, '
                   .'other instances are not supported.'
                );
            }
    
        }
    }
    
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types inside the if block in such a case.
  1. Add the method to the interface:

    interface User
    {
        /** @return string */
        public function getPassword();
    
        /** @return string */
        public function getDisplayName();
    }
