upload_pass not called on error

[ghost]

Hello @fdintino, @vkholodkov ,

First of all, congratulations on this upload module that is very interesting.

On upload errors, the location hook defined within the upload_pass <location> directive is not called. In my application, I would like to perform internal operations when the upload fails.

The directive upload_cleanup <codes> does not accept a location to call on error.

Is there an existing option to implement a directive upload_error @error_hook for being notified on all errors ? Or maybe upload_cleanup <codes> <error_hook> ?

Thanks in advance.
