Is it possible to disable cache? about glide HOT 12 CLOSED

Not at the moment, no. I had no idea anyone would ever want to that, but that makes sense if you're using Varnish. Can you leave this with me to add a new method for this? For the time being maybe just save the cached files to sys_get_temp_dir()?

I probably found the solution. IIRC there is a null adapter in flysystem. That might work.

Haha, yep, that would probably work too. ;)

Is this repo free for pull requests? I'd like to add something like this:

Current situation:

    /**
     * Get the source file system.
     * @return FilesystemInterface The source file system.
     */
    public function getSource()
    {
        $source = null;

        if (isset($this->config['source'])) {
            $source = $this->config['source'];
        }

        if (is_string($source)) {
            return new Filesystem(new Local($source));
        }

        if ($source instanceof FilesystemInterface) {
            return $source;
        }

        throw new InvalidArgumentException('Invalid `source` parameter.');
    }

Preferred situation:

    /**
     * Get the source file system.
     * @return FilesystemInterface The source file system.
     */
    public function getSource()
    {
        $source = null;

        if (isset($this->config['source'])) {
            $source = $this->config['source'];
        }

        if (is_string($source)) {
            return new Filesystem($this->adapter($source, $adapterclass));
        }

        if ($source instanceof FilesystemInterface) {
            return $source;
        }

        throw new InvalidArgumentException('Invalid `source` parameter.');
    }
// Add the source and the adapter, f.e. 'League\Flysystem\Adapter\Null'
    public function adapter($source, $class)
    {
        return new $class($source);
    }

Hi @xtrasmal, can you explain to me exactly what you're trying to do? I'm sort of confused. If you're simply trying to pass the Null adapter to the Glide factory you can just do this:

$server = League\Glide\ServerFactory::create([
    'source' => 'path/to/source/folder',
    'cache' => new League\Flysystem\Adapter\Null(),
]);

from glide.

Hi @reinink, passing an instance of Flysystem's NullAdapter (there is no Null) as you suggested does not work:

InvalidArgumentException in ServerFactory.php line 90:
Invalid `cache` parameter.

I believe it has to do with the following check on line 86 of ServerFactory.php just before the InvalidArgumentException gets thrown:

if ($cache instanceof FilesystemInterface) {
    return $cache;
}

Because: NullAdapter extends AbstractAdapter which implements AdapterInterface which extends ReadInterface. So it is not an instance of FilesystemInterface.

I believe this is a bug as there is currently no way to turn off caching, which I would like to so as to let a CDN handle caching managed by headers.

Thoughts?

Yeah, agreed, I'll add the option to disable the cache in an upcoming release.

Is there a way to delete the cached files for a particular image?
Say i have a profile image getting uploaded to the S3 which is scaled at different ui, when the user changes the image it wont change the image endpoints but glide actually serves the old cached images based on old requests.

@shyam-achuthan What you're describing is cache invalidation; something that is discussed in another issue.

From my understanding, there is currently no cache invalidation handling in Glide. I submitted a pull request to allow disabling of the cache so that caching - and invalidation - could simply be handled by another layer like a CDN (e.g. Amazon CloudFront) or a reverse proxy (e.g. Nginx).

cache invalidation 👍

That is my problem

Hey all, I've finally got a good solution to this cache disabling problem. See #56.
