Check if you can write to the Torrent's Directory before starting to download

[puunjab]

I use TrueCrypt? for Mac in order to encrypt all my downloads and I leave a 20 gig encrypted directory as the default location for Transmission torrents.

If I forget to mount the encrypted drive first, Transmission still starts to download the torrent for up to a couple of minutes before it figures out that the drive is not there. I am guessing you use a temp space buffer/file in the beginning or it's done in memory. Then the torrent fails with an "unable to write to directory" type message.

If I save the torrent files, delete them, and then re-add them after I mount the TrueCrypt? drive, Transmission crashes. It's probably due to some pointer held over in memory. It's not a major issue and I always can work around it.

But, I think it would be better for you to simply check if you have write permission to the torrent's directory before you start downloading. Doesn't matter if it's a magnet or an actual torrent file. You need permission to write to the torrent's directory or why start downloading?

Otherwise, I can kick one off expecting it to have completed before I ever realize I forgot to mount the drive.

Thanks.
