break_torrent
- TriggerRepair

repair_torrent
- Repair: started repair process

mark_as_repaired
- convertToTorrent: if all links are intact
- mergeTorrents: file statistics brokenCount==0, okCount > 0
- repair: after reinsert the whole torrent, progress == 100, checked broken links
- assignLinks: when the only link is a rar, then it's not really broken (just unplayable)

-----------------------------

break_file
- DownloadFile: cannot be unrestricted
- streamFileToResponse: error downloading the url
- streamFileToResponse: status code != 2xx

repair_file
- convertToTorrent: if all links are intact
- assignLinks: when we find the matching file
- isStillBroken: same approach as convertToTorrent (all links are intact), this is only called on repair method no.1 and progress == 100 immediately

delete_file
- HandleDeleteFile: when only the file is deleted, not the whole torrent
