Bug description
The config setting 'use_presigned_url' => true does not produce presigned URLs.
When I force it to set true adding it directly to the function __construct(array $parameters) it starts to work correctly though.
It's very likely it's because getConnection() in file lib/private/Files/ObjectStore/S3ConnectionTrait.php is called lazily, not at construct time.
isUsePresignedUrl() (line 298) can be called before getConnection() has ever been invoked- in that case,
$this->connection is still null, but the early-return guard means the assignment on line 112 hasn't run yet
- so
isUsePresignedUrl() returns the hardcoded default false, regardless of the config
Steps to reproduce
- 'use_presigned_url' => true
- No presigned URLs in DAVs request:
