Christoph Wurst 2c9cdc1cdb Add our own DB exception abstraction Right now our API exports the Doctrine/dbal exception. As we've seen with the dbal 3 upgrade, the leakage of 3rdparty types is problematic as a dependency update means lots of work in apps, due to the direct dependency of what Nextcloud ships. This breaks this dependency so that apps only need to depend on our public API. That API can then be vendor (db lib) agnostic and we can work around future deprecations/removals in dbal more easily. Right now the type of exception thrown is transported as "reason". For the more popular types of errors we can extend the new exception class and allow apps to catch specific errors only. Right now they have to catch-check-rethrow. This is not ideal, but better than the dependnecy on dbal. Signed-off-by: Christoph Wurst <christoph@winzerhof-wurst.at>	2021-01-12 16:38:23 +01:00
