Bug Description

Some torrent files includes files with cyrrilic names and length more than 128 chars. For example: http://rutracker.org/forum/viewtopic.php?t=1445641
When qbittorrent tries to create this file on linux, it emits error: "I/O Error: File name is too large"
Please, add workaround for this bug. For example if file name is too long, rename it to something else

Could you please attach the torrent instead of the link? I'm not registered with this tracker.

And why do you say 128 chars? As far as I know, ext3 and ext4 support 255 chars. 255 bytes in UTF-8 (1 byte per character).

However, I do agree that renaming on the fly to avoid this problem would be useful.

This was fixed n SVN for v2.7.1, thanks a lot!

You were actually partially right. Some languages such as Russian and Chinese need more than 1 byte per character/idiogram (2 bytes for Cyrillic and 3 bytes for Chinese idiograms). The patch should work for all languages and I confirmed that it works fine with the torrent you provided.

How exactly does this patch fix the issue?

I installed Debian unstable's 2.9.2-1 package to try to download http://www.nyaa.eu/?page=torrentinfo&tid=256613 and when I load the .torrent as an argument, qbittorrent seems to ignore it, and when I load it with 'add', it ignores it; when I use the import-existing-torrent function, the moment I select that torrent, qbittorrent immediately tells me that it is an invalid .torrent.

So does all this patch do is not let one run a torrent with long file names?
