Hence, WHAT exactly has been deleted here? :-)


That removed revision files for me.



Hi,
so at last I see why not only the webserver user should be in eprints' main group but also vice versa: For instance, only then eprints user can delete files created by a webserver process.
Now I got still to figure out why deletion fails for some files. $file->remove returns a false value in those cases. The sources suggest that can happen only when the file path is undefined (how come?), or when system call unlink() returns false. The latter is rather unlikely as I succeeded deleting the file manually as user eprints.
Therefore I debugged a bit and it turned out that method EPrints::Plugin::Storage::Local::_filename (line 203ff) returns an empty array in the case that $eprint is undefined... does that mean I cannot get rid of histories and revisions associated with eprints that have already been removed? Is it intended that those survive the deletion at all?
By the way, while testing that, there I guess would be no need for run/restore loops if EPrints removed the file record *upon successful* deletion of the file itself.
By another way heading a better users' experience: When cancelling the creation of an eprint in the web interface workflow, i.e. with all fields left empty, you still have to delete the eprint entry from the database manually in order to keep your inbox clear. Potentially annoying.

You may need to manually remove revision files if they have no
associated history object ...
