Extension:UploadWizard/Error behavior
From Linux Web Expert
Invalid extension:
- Report on first step and reject this file (but accept other valid files)
Too large:
- Report on first step and reject this file (but accept other valid files)
Duplicate file contents:
- Report on first step (immediately after upload) and reject this file (but accept other valid files)
File was previously deleted:
- Minimally acceptable behavior: Report on first step (immediately after upload) and reject this file (but accept other valid files)
- Ideal: As above, but trigger an interactive warning that allows the user to override.
File with same name was previously deleted:
- Discard and ignore this warning (this is pretty useless information in almost all cases)
File name checks:
- File name matches title blacklist,
- File name exists
- File name exists once name is normalized (e.g. "JPEG" to "jpg")
- File name is protected
- File name includes invalid characters
- Because the file is initially uploaded to the temporary stash using a unique identifier, all these checks only need to be performed at the third stage ("Describe"), at which point the user should be forced to choose valid titles for all files
- If for whatever reason a bad name slips through the third step, there is a final catch-all in the fourth step allowing the user to correct file names.
