[bug] CacheItem must be compatible

[c-o-m-m-a-n-d-e-r]

Hi,
i'm getting the same Error like here:
https://community.humhub.com/comment/perma?id=51033

The Error is :
Declaration of Detection\Cache\Cache::get(string $key, mixed $default = null): ?Detection\Cache\CacheItem must be compatible with PsrExt\SimpleCache\CacheInterface::get($key, $default = <default>)

Already tried reinstalling via composer without luck.

Usage is only:
use Detection\MobileDetect; $detect = new MobileDetect(); $isMobile = $detect->isMobile();

@c-o-m-m-a-n-d-e-r thanks for mentioning this issue as well as the community message with my comments about the issue;

@serbanghita currently for a number of my clients that are using @humhub as of v1.17.0-beta.4 which introduces this package can not be updated correctly due to the Cache class not being compatible with the interface, and I've had to use the following complete code and manually do this with a number of instances already;

Complete Code

Replace https://github.com/serbanghita/Mobile-Detect/blob/4.8.x/src/Cache/Cache.php to be compatible with CacheInterface class. I leave this code to be either adapted or modified by the maintainer.

<?php

namespace Detection\Cache;

use Psr\SimpleCache\CacheInterface;
use Psr\SimpleCache\InvalidArgumentException;

class Cache implements CacheInterface
{
    protected array $cache_db = [];

    public function count(): int
    {
        return count($this->cache_db);
    }

    /**
     * @return array{string}
     */
    public function getKeys(): array
    {
        return array_keys($this->cache_db);
    }

    public function get($key, $default = null)
    {
        if (!is_string($key) || $key === '') {
            throw new InvalidArgumentException('Invalid cache key');
        }

        return $this->cache_db[$key] ?? $default;
    }

    public function set($key, $value, $ttl = null): bool
    {
        if (!is_string($key) || $key === '') {
            throw new InvalidArgumentException('Invalid cache key');
        }

        $this->cache_db[$key] = ['value' => $value, 'ttl' => $ttl];
        return true;
    }

    public function delete($key): bool
    {
        unset($this->cache_db[$key]);
        return true;
    }

    public function clear(): bool
    {
        $this->cache_db = [];
        return true;
    }

    public function getMultiple($keys, $default = null): iterable
    {
        $results = [];
        foreach ($keys as $key) {
            $results[$key] = $this->get($key, $default);
        }
        return $results;
    }

    public function setMultiple($values, $ttl = null): bool
    {
        foreach ($values as $key => $value) {
            $this->set($key, $value, $ttl);
        }
        return true;
    }

    public function deleteMultiple($keys): bool
    {
        foreach ($keys as $key) {
            $this->delete($key);
        }
        return true;
    }

    public function has($key): bool
    {
        return isset($this->cache_db[$key]);
    }
}

@c-o-m-m-a-n-d-e-r how do you install and update HumHub?

From the zip? https://docs.humhub.org/docs/admin/installation#download-and-extract
From git? https://docs.humhub.org/docs/develop/environment#gitcomposer-installation
A mix of both (e.g. also using the Updater module)?

It seems that you install it from git if you use composer.

• When you do a composer update, have you any warning?
• What is your PHP version (in command line, when updating composer)?
• Could you copy/paste here the result of composer show -i? (@ArchBlood that could be interesting too, to have your list)

What cache are you using? Have you got specific configuration in your common.php file, such as some similar to:

        'cache' => [
            'class' => \yii\caching\DummyCache::class,
        ],

Thank you for your help.

[c-o-m-m-a-n-d-e-r]

@marc-farre sorry i don't use HumHub ... i had the same error in another project so i do some research and found the solution from @ArchBlood

[marc-farre]

@c-o-m-m-a-n-d-e-r Sorry, by receiving a notification about this topic, I thought I was writing in the HumHub Git repository...

However, if both of you could send me the result of composer show -i, it could interesting to see what library versions you are using.

[ArchBlood]

composer show -i

From my end I see no issues;

[marc-farre]

@ArchBlood Thanks. I compared with a diff tool, and I have the same list (some versions could be updated, but I doubt it will fix this issue).

[ArchBlood]

@marc-farre here is my final judgement about this issue, the Cache class doesn't fully comply with PSR-16 due to the following;

1. Return Type of get Method

• Issue: PSR-16's get method must return mixed. This get method returns CacheItem|null, which is incompatible.
• Fix: Update the get method's return type to mixed.

---

2. get and set Exceptions

• Issue: The PSR-16 specification states that get and set should only throw Psr\SimpleCache\InvalidArgumentException if the key is invalid. The code throws a custom CacheException, which is not part of PSR-16.
• Fix: Ensure CacheException implements Psr\SimpleCache\InvalidArgumentException or replace it with the appropriate exception type.

---

3. getMultiple Return Type

• Issue: PSR-16 requires getMultiple to return an iterable where the keys map to their corresponding values or $default. This implementation does not respect the $default parameter for keys that are missing.
• Fix: Update getMultiple to properly handle missing keys by returning $default for them.

---

4. setMultiple Parameter Type

• Issue: According to PSR-16, the $values parameter in setMultiple must be an iterable of key-value pairs. The PHPDoc specifies array<array{key:string, value:string}>, which is incompatible.
• Fix: Adjust the PHPDoc and ensure that $values is processed as key-value pairs.

---

5. set TTL Handling

• Issue: PSR-16 mandates that the $ttl parameter should accept null (for no expiration), an int (time in seconds), or a DateInterval. This implementation appears correct here, but needs to ensure that these cases are handled appropriately.

---

6. Custom CacheItem Class

• Issue: PSR-16 does not use or require a CacheItem class. The CacheItem in the code is not defined here, and its compatibility with the interface is unclear.
• Fix: Avoid using a custom CacheItem unless necessary and ensure compliance with PSR-16.

---

7. count and getKeys Methods

• Issue: These methods are not part of PSR-16 and add unnecessary API surface area. While they are harmless in a broader sense, they deviate from the interface.
• Fix: Remove methods not defined in the PSR-16 interface or document them clearly as extensions.

[ArchBlood]

#978 (comment) will fix the issue, but it can always be improved for backwards compatibility which is what I think was the intent of the current implementation?

[serbanghita]

@ArchBlood thank you so much about the details, I will provide a patch asap. I'd need a bit of help with reviewing the final PR, do you mind If I add you as a reviewer of that?
