I recognize that git annex importfeed is reloading old files for a second time while prepending the file name with "2_".
So if there is a podcast file called "foo_bar_in_baz_20170101.mp3" it now imports the same file again naming it "2_foo_bar_in_baz_20170101.mp3".
As I cannot imaging that the feed provider is renaming the files I guess that something else is triggerin this behaviour. Any ideas?
TIA juh
RSS feeds have unique IDs that are attached to a post in the feed. They are supposed to be allocated once and remain unchanged. It's not entirely uncommon for the unique IDs to change (due to broken feed generation software, changing feed generation software, etc), and then git-annex thinks this is a new file in the feed, that happens to have the same title as another file, so it makes up a unique name for it with the "2_".
Since the alternative is to miss downloading new files from the RSS feed if they happen to have the same title as a previous file, I think we have to live with this.
(git-annex was improved in version 5.20150727 to avoid some cases of this)
