File duplicates are not handled and may cause important issues

[midenok]

What came wrong with qbittorrent? Apart from ugly toolbar design it introduced feature with '.unwanted' directory which works wrong. The usage pattern is torrent redownload with some files added. The operations were done in roughly such order:

1. Pause old torrent
2. Add new torrent (with same location to old torrent)
3. Pause new torrent
4. Uncheck files in new torrent that were downloaded in the old torrent
5. Delete old torrent (keeping files)
6. Start new torrent

After that it complained multiple times that file is absent in .unwanted and paused. After several start attempts it finally continued the downloading. Which looks weird by itself, so the complain looks needless (groundless). But after that I discovered that all old files were gone...

qBittorrent does not handle file duplicates well at the moment (it never has). This is on my TODO list.

I'm extremely busy at the moment but I'll do my best to fix it before next release.

Thank you! You are doing great job.

Btw, creating .unwanted directory is not always friendly. This better should be configurable. If this is all about traffic saving then in our days of terrabyteful traffic this is rarely needed.

If I delete files in .unwanted it starts naggily complaining about absent files and stopping. The user interaction here is not needed. It should handle this situation by itself, silently.

I have a similar problem (I think its someway similar)...
For example... i downloaded a torrent with another client... and now i want to seed it with Qbittorrent... but i cant recheck it... it just does not recognizes the already downloaded files... it starts downloading all over again... just sometimes (by unknown reasons) it recognizes the files and rechecks them correctly.

¿It is the same problem?

Thanks

This should be fixed for v2.7.3. Please reopen if you still experience the problem. The fix is already on my PPA if you're using Ubuntu.

@pandarean: No, your problem is unrelated. As far as I know, torrent checking/resuming is working fine provided that you use the exact same download path as before.

Hi, then.. I should open a new bug or a questiion.. bacause Im experiencing some problems with the checking thing. I'll review this and post it later. Thanks
