There is a failure on Queue tests, but this PR touches only FileStorage, maybe future merges can solve this. |

Would be nice to use exception filters here

In this specific case, trace/debug logging I think isn't needed, because in case of not-managed error, an exception is thrown to the caller. |

We definitely don't want to have exceptions that are unique to each implementation where a user would need to check for different kinds of exceptions depending on which implementation they are using.

@frabe1579 I think this was the main concern with merging this PR. We don't want to have different exceptions being thrown per implementation.

Sorry I'm not comfortable with branches and pull-requests. I've removed S3FileStorageException and corrected code. Can you see it?

Yes, thank you, we can delete this file.

I'm going to work towards merging this pr then create a StorageException in the core library and update the core implementations and then update this line (post merge) to use this new exception type.
Thanks again for the pr!

@frabe1579 could you please address Erics comments, would love to get this merged. |
Use more generic exception for error in GetFileInfo
This PR changes GetFileStreamAsync, GetFileInfoAsync, and ExistsAsync.
The changes test for precise response status code, in order to avoid silent catching of particular S3 errors.
All tests passes, but not new tests were added because of the difficult to simulate errors. A classic error simulation is network error, but this already throws other exceptions.
