Add preference exclude_by_attribute (boolean). If true:

  • macOS: will exclude all files that have xattr that contain the value
  • Linux: will excluded all files that have xattr dulicacy_exclude.

Tests Included, tested on macOS afps and Debian ext4

Fixes #478

I named the preference "exclude_by_attribute" and not "exclude_attribute" to make it clear this doesn't affect the storage of attributes on the files.
Alternatively this could be named something like "file_exclude_attribute"


  • Reading Attributes
    • I see that attributes are not always read based on backups size and DUPLICACY_ATTRIBUTE_THRESHOLD. I didn't change the existing code to force a read of the attributes when this occurs. However I think that if exclude_by_attribute is true that it should read the attributes and discard them at least (or call xattr.Getxattr directly on the file if discardAttributes is true). Based on input I can update the pull request.
  • Configurable Attributes
    • I started building out other preferences to make this configurable and possibly support multiple attributes. However I was hesitant to add event more new preferences and adding more parameters to ListEntries(). I can update the pull request with input on design if requested. I think the best design would be to change the bool into a map[string]string like the Keys preference. Based on input I can update the pull request.
