Start all torrents auto-managed to prevent simultaneous checking
of multiple torrents.
Handle checking state of paused torrent to prevent it from being
resumed when qBittorrent is closed until checking isn't complete.
TorrentInfo::origFilePath will return the very original path from
.torrent file, not the most recent file path before the rename operation
and thus the code would not be working as we expected.
Add/restore all torrents in "paused" state and then resume those
that need to be really "resumed" (added/restored in "resumed" state).
Keep torrents with missing files paused.
Force recheck torrent with missing files when it's resumed by the user.
Updating file priorities is an async operation in libtorrent, when we
just updated it and immediately query it, we might get the
old/wrong values, so we rely on `updatedFilePrio` in this case.
Don't post "torrent resumed" event when torrent starts in "resumed"
state.
Fix confusing names. Now "resumed torrent" means "unpaused torrent"
only. When we load previously added torrent it is called "restored
torrent".
This is another indication to the user that something is happening
behind the scenes.
Uses the same icon/color as "Checking" status.
Torrents in the `Moving` state are considered as "Active". This should
prevent accidental program exit from the user and inhibit system sleep.
Libtorrent can recheck only unpaused torrents. We get around this by
unpausing the torrent, issuing the recheck and pausing again after we
get alerted by libtorrent that the recheck has finished. This alert is
asyncronous. There is a small time frame where the program might start
downloading and writing data to the file before we pause it. This can
lead to data corruption if the file on disk is totally different that
the one expected by the torrent AND the file on disk is a valid file on
its own. OR in case the user points the new torrent to the wrong
directory by mistake.
To get around this the torrent is placed in upload_mode and out of
automanagement.
