Set ignore status.

is_active

download active?

is_complete

is_ghost

Shining a light on the naming and paths mess:

hash=xxx for i in d.name d.base_filename d.base_path d.directory d.directory_base d.is_multi_file; do

echo -n “$(printf ‘%20.20s ‘ $i)”; rtxmlrpc $i $hash

done

Basics:
  • d.base_filename is always the basename of d.base_path
  • d.directory_base and d.directory are always the same
  • d.base_filename and d.base_path are empty on closed items, after a restart, i.e. not too useful (since 0.9.1 or so)
Behaviour of d.directory.set + d.directory_base.set (tested with 0.9.4):
  • d.base_path always remains unchanged, and item gets closed
  • d.start sets d.base_path if resume data ok
  • single:
    • d.directory[_base].set → d.name NEVER appended (only in d.base_path)
    • after start, d.base_path := d.directory/d.name
  • multi:
    • d.directory.set → d.name is appended
    • d.directory_base.set → d.name is NOT appended (i.e. item renamed to last path part)
    • after start, d.base_path := d.directory
Making sense of it (trying to at least):
  • d.directory is always a directory (thus, single items auto-append d.name in d.base_path and cannot be renamed)
  • d.directory_base.set means set path PLUS basename together for a multi item (thus allowing a rename)
  • only d.directory.set behaves consistently for single+multi, regarding the end result in d.base_path
